Grain processing machinery According to the process is divided into two categories: one class is used for rice, sorghum, corn and millet and other raw grains dehulled and peeled, milled into finished rice. For example, the original rice grain is first removed by a variety of removal and cleaning equipment to remove various impurities, enter the huller and separation of rice husk. The discharged grain and brown mixture into the grain and brown separation sieve. Separation sieve using rice and brown rice in the particle size, density and surface characteristics of the difference, the unhulled rice separated out and sent back to the huller. The brown rice then enters the rice milling machine to be milled into white rice, and then through the finished product grading screen to remove the chaff and broken rice, that is, the finished white rice. Another category is used for wheat, corn, barley, buckwheat and oat and other raw grains to remove the skin and germ, grinding into finished powder. For example, wheat grains by a variety of impurity removal and cleaning equipment to remove a variety of impurities and dirt, dust attached to the surface of the wheat grain, into the mill grinding powder, and a set of flat sieve sieve to extract the finished flour. The intermediate material then enters another mill to grind, and so on repeatedly to extract the flour, and finally by brushing the bran machine will be discharged bran.

Oilseed processing machinery oil production process is mainly divided into pressing method, leaching method. Different oil production process using different machinery and equipment, but the oil raw materials are first cleaned up by the oil cleaning machinery to remove impurities, and with various types of oil shelling machine to remove the shell and make the shell kernel separation, and then pressed into the embryo with the embryo rolling machine embryo material. With the leaching method, the embryo material will be immersed in the solvent (hexane or light gasoline) to leach the oil, by filtration, evaporation and vaporization equipment to make the oil and solvent separation, solvent recovery can be used repeatedly; with the pressing method, the embryo material will be placed in the steam frying pan after the frying, sent to the spiral oil press or hydraulic oil press to extrude the oil. Leaching or pressing out of the gross oil and then by a variety of refining equipment, filtration, hydration, alkaline refining, acid refining, decolorization and deodorization refining into essential oil or finished oil.

Livestock industry machinery

In the grazing and housing poultry, livestock rearing production process used in a variety of mechanical equipment.

Grassland maintenance and improvement of machinery, including the killing of pasture rodents with bait spreading machine, improve the pasture to improve pasture production of soil replenishment seeding machine and pasture sprinkler irrigation equipment and so on.

Rangeland management equipment, including electric fences and their erection of machinery, mobile epidemic prevention vehicles and drug shower equipment. ① electric pasture fence: the electric pulse generator produces high-voltage pulse current into the electric fence, so that livestock in the touch of the electric fence by the non-lethal electric shock, so that it is surrounded by the electric fence in the electric pasture fence activities, foraging. Installation of solar energy or wind generator, can provide convenient and cheap power for the electric grazing fence. ② mobile epidemic prevention vehicle: a cross-country performance of a special car, the car is equipped with epidemic prevention and veterinary laboratory, disinfection, treatment equipment and internal combustion generator sets, etc., can carry several epidemic prevention or veterinary personnel in a timely manner to the infected area. ③ Medicine drenching equipment: mainly used for the prevention and control of grazing sheep scabies and body surface parasites.

Pasture and green fodder harvesting machinery in the field to collect pasture and the formation of loose grass, grass bundles, grass stacks and grass and other machinery, mainly including mowing or mowing modulator, raking machine, picking up the pressure of bundling machine, set grass stacking machinery, pasture loading and transportation of machinery and green fodder harvester and so on. There are two types of mowers, reciprocating and rotary, and the rotary mowers developed in the 70's, compared with the traditional reciprocating, have the advantages of high speed of cutting and advancing, smooth work, and strong adaptability to the pasture, which is suitable for high-yield pasture, but the cutting is not neat enough, and the re-cutting is more, and the energy consumption is larger. The addition of pressure rollers on the mower becomes the mowing modulator, which can flatten and squeeze the cut fresh forage stalks to accelerate the drying process. Straddling machine has two types of lateral and lateral, used to cut down the scattered spread on the ground grass straddling into different forms of grass. Pick up the press bale machine is used to pick up from the ground into strips of hay, and will be compressed into a rectangular or round cross-section of the tight bale, in order to facilitate transportation and storage. There are two types of green fodder harvester, the dumping knife type and general-purpose type. The former with a high-speed rotating knife-type chopper to the green forage crop cut, chopped and thrown to the trailer, mainly used for harvesting low green forage crops. The latter is equipped with three kinds of attachments: full-width cutting harvesting platform, row harvesting platform and picking device, so it can harvest all kinds of green fodder crops.

Feed processing machinery mainly includes: processing a variety of coarse and concentrate feed milling machine, hoeing machine and green fodder chopper; preparation of mixed feed feed mixer; powdered feed into granular feed pelletizer; processing of straw fodder stalk modifier; for the processing of potatoes, melons and vegetables, such as juicy fodder washer, slicing machine, shredding machine, pulper, vegetable puree machine and feed grain cooker and so on.

The poultry and livestock rearing and management machinery mainly includes: livestock house ventilation, temperature control and lighting and other environmental control equipment; livestock feeding and drinking water equipment; livestock epidemic prevention equipment; in addition to manure and feces treatment equipment, as well as egg collection and milking equipment, and so on. Modern laying hen house includes a complete set of mechanized and automated equipment from hatching and brooding to egg crating, which can automatically control the environment of the house according to the requirements under the condition of isolation from the outside world. According to different age and laying hens' needs, full-price feed is fed in quantitative quantities, and automatic water dispenser and regular feces removal equipment are installed. Eggs are automatically collected through an egg collection system, cleaned and graded, and then boxed for transportation.

Crop Harvesting Machinery

Crop harvesting machinery includes a variety of machinery used to collect a variety of crops or agricultural products. Different crops are harvested in different ways and the machinery used. Some machines are only a single harvesting process, such as rice, wheat, corn and sugar cane stalks with ears of cutting; potatoes, sugar beets and peanuts, such as the underground part of the excavation; cotton, tea and fruit picking; flax, jute, such as stalks of plucking and so on. Some harvesting machinery can be carried out at a time all or more than one harvesting process, known as the combine harvester. For example, grain combine harvester can be stalk cutting, grain threshing, straw separation and grain cleaning and other operations; potato combine harvester can be excavated, separated from the soil and potato collection operations. (See color map)

Grain combine harvester consists of harvesting platform, conveying device, threshing device, separation device, cleaning device, grain tank and transmission device. According to the crop feeding method there are two kinds of full-feeding type and half-feeding type. Europe and the United States are using full-feed grain combine harvester (Figure 6), mainly used for harvesting wheat and other wheat crops, can also be used for harvesting corn, beans, rice and sunflower after some modifications and adjustments. During operation, the reciprocating cutter at the front end of the harvesting platform, with the cooperation of the paddle wheel, cuts down the stalks with ears on the harvesting platform, and sends them to the threshing device through the harvesting platform conveyor and the intermediate conveyor, and then they are threshed by the action of rubbing and striking when passing through the gap between the threshing drum and the concave plate. Most of the grain through the concave plate sieve into the cleaning device, a small amount of grain entrained in the concave plate in the dislodged material is thrown to the separation device, in the chain separation device up and down, before and after the reciprocating shaking of the grain is separated out into the cleaning device, the stem draft and other large debris is conveyed backward and thrown out of the machine. Into the cleaning device of the grain by the fan and sieve to remove small impurities, clean grain is sent to the grain tank. After the grain tank is full, start the unloading conveyor, the grain will be unloaded into the grain truck. in the mid and late 70s, in North America appeared in a variety of types of axial drum full-feeding grain combine harvester, which will be threshing device and separating device is combined into a single unit, so as to dispense with the huge chain separating device, to shorten the length of the whole machine. In southern China and Japan have developed semi-feed grain combine harvesters mainly for rice harvesting. Operation, cut rice straw in the clamping conveyor process only the head part into the threshing device, after threshing straw is more complete, easy to comprehensive utilization. Mixed in the grain in the amount of broken straw is small, generally do not set up a separate separation device, so compared with the full-feeding type, the structure is simple and less power consumption.

Cotton picker It uses a rotating picking spindle with teeth, will bloom the seed fibers in the cotton peanuts to catch and bring out and by airflow into the cotton box. There are two main types of cotton picking machine: in the United States use horizontal spindle picking machine, its picking rate is higher, but the structure is complex, manufacturing precision requirements and high cost; in the Soviet Union, most of the use of vertical spindle picking machine, its structure is simpler, lower cost, but the picking rate is lower, more cotton on the ground, more damage to the cotton plant.

The machine picking seed cotton has a high rate of impurity, the quality level is significantly lower than the hand-picked seed cotton. Machine-picked seed cotton needs to be equipped with a complete set of cotton cleaning equipment, picking the cotton before and after ginning to repeatedly clean up before being used as textile raw materials. Agricultural transportation machinery

Agricultural transportation machinery used to transport a variety of agricultural by-products, agricultural means of production, construction materials and rural means of subsistence, including a variety of agricultural vehicles, by the car or tractor trailers and semi-trailers, livestock rubber wheeled carts, rubber wheelbarrows, and farm boats and so on.

Tractor-drawn trailers and semi-trailers and automobile-drawn trailers and semi-trailers are similar, but the location of the hook-up point is lower, and there are many different forms of compartments to adapt to the transport of different agricultural materials, such as bulk grains and feed trailers; pasture and green fodder trailers; hay bale transporters; sugarcane transporters; fresh livestock transporters; stable fertilizers, fertilizers, and liquid fertilizers transporters; and agricultural implements, such as transporters. Part of the weight of the semi-trailer is pressed on the tractor's traction device through the traction bar, so that the tractor driving wheel is weighted to facilitate the traction force of the tractor.
