This paper mainly introduces how the small-sized corn harvester realizes straw crushing and what are the main points of daily maintenance of the small-sized corn harvester. First of all, the small-sized corn harvester realizes straw crushing by starting the motor and driving the pulley according to the principle of hammer strike, which drives the rotor disc and hammer of the main shaft to repeatedly rotate and strike the corn straw, and the straw with crushing fineness is filtered out through the screen. Secondly, the daily maintenance essentials of small corn harvester include checking the reliability of steering and braking system and checking the oil level of oil tank in hydraulic system. Let's take a closer look at the specific text! 1. How does a small corn harvester realize straw crushing?

Small corn stalk crusher is a machine for crushing straws, so how does a small corn harvester crush straws?

The small-sized corn stalk pulverizer mainly starts the motor and the belt pulley to drive the rotor disc and the hammer of the main shaft to repeatedly rotate and hit the corn stalk through the hammer blade striking principle, so that the pulverized straw can be filtered out through the screen.

Second, what are the daily maintenance essentials of small corn harvesters?

In recent years, driven by the national subsidy policy, small corn harvesters have been widely used in the vast rural areas because of their small size, flexible rotation, compact structure, low failure rate, low power consumption, good working quality and high efficiency. Mechanical equipment should be maintained and overhauled in daily use, which can not only effectively reduce the occurrence of faults, but also prolong the service life of the machine, and small corn harvesters are no exception. Small corn harvester is a new type of agricultural machinery and equipment, and many friends don't know much about its daily maintenance and overhaul. The following summarizes some matters that should be paid attention to in the daily maintenance of small corn harvester, and now introduces them in detail:

1, check whether the instruments and holding mechanisms in the cab are normal.

2, check whether the conveyor trough, inclined conveyor chain rake is loose, whether the tension is appropriate, adjust and tighten in time.

3. Check the reliability of the steering and braking system.

4. Check the position of adjustable telescopic teeth, and revise the deformed auger blades.

5. Check whether the tension of the V-belt and chain of the small corn harvester is appropriate, and whether the pulley and sprocket are loose. Adjust the tensioner in time and tighten the pulley and sprocket.

6. Check the oil level of the oil tank of the hydraulic system, whether the connecting joints of the oil circuit are leaking, and whether the flange connection and fixation are loose. If the hydraulic oil is insufficient, it should be added in time. If leakage or looseness is found, it should be welded, fastened or replaced in time.

7. Check the water level of the engine water tank, the oil level of the fuel tank and the bottom shell of the diesel engine, and add them in time if they are insufficient.

8. Check the connection and margin of electrical circuits, and repair any damage or poor contact in time.

9. Check the sealing state of the sealing plate, shaking plate, threshing part and hole cover at the entrance of the drum, and there shall be no grain leakage.

10, check whether the fastening parts of the frame, the gear train, the tie-rod fastening nuts or locking pins are loose or fall off, and fasten and replace them in time.
