A new compound corn combine has been developed successfully.
In recent years, the development, production, popularization and application of corn combine harvester has been a hot spot of agricultural mechanization, attracting many scientific research units and production enterprises. According to incomplete statistics, by the end of 2000, there were more than 60 corn combine harvesters in China, with more than 20 products and more than 80 models. However, due to the complexity of corn planting and harvesting methods in China, the limitation of the working principle of traditional corn harvesting machinery, the immaturity of technical design and the instability of manufacturing quality, many products have problems such as high power consumption, low working efficiency, poor straw crushing effect and the inability to treat stubble at one time, which makes corn harvesting a bottleneck restricting the development of agricultural mechanization in China. Now, after three years of hard exploration and unremitting efforts, Huatai Machinery Research Institute of Qingzhou City, Shandong Province has successfully developed a new compound corn combine harvester based on the utilization of whole corn stalk, with a new breakthrough in working principle and three national patents (including an invention patent). Compared with the popular corn combine harvester at present, it completely gets rid of the shackles of traditional principles, and its structural design is unique and innovative, which creates a precedent for the utilization of corn straw as a whole. The main performance can be summarized as three major innovation breakthroughs and eight unique advantages. Three major innovation breakthroughs: First, the innovation breakthrough of working principle. Different from the traditional principle, the mechanical operation flow is: digging the whole corn by itself → rotating the cutter to remove the root soil after the stubble leaves the ground → conveying the whole corn to the ear-picking roller → picking ears, and then dividing the soldiers into two ways, one way is ear-lifting → cutting table → hydraulic lifting and unloading, and the other way is straw transportation and separation → squeezing juice, followed by juice collection or spraying, and straw crushing and returning to the field or straw residue. The second is the innovative breakthrough of comprehensive development and utilization of straw. This machine can not only extract corn straw juice used as livestock feed and fertilizer for flowers, fruits and vegetables, but also conveniently collect and utilize crushed straw residues, especially for pulp production, which can reduce environmental pollution in the production process. The third is the innovative breakthrough of corn stubble treatment. This machine completely solves the problem of stubble cleaning that puzzles farmers and reduces a stubble breaking operation for farmers. Eight unique advantages: first, it consumes less electricity, saving about 40% electricity compared with traditional models; Secondly, the straw is chopped in the machine, and the effect is good; Thirdly, the vertical combined counter-rolling ear picking roller is adopted, which is small in size, light in weight, good in ear picking effect and small in harvest loss; Fourthly, the ear lifting mechanism has the function of removing impurities; Fifth, the hydraulic lifting and tilting mechanism of the ear box is light and practical, and the lifting height is adjustable, which greatly facilitates the unloading of grain and saves the unloading time; Sixth, a large number of chain and belt drives are used, and the traditional gear box is replaced by a unique chain box, which simplifies the structure, reduces the cost and is convenient for maintenance; Seventh, the mature parts of small four-wheeled tractors and three-wheeled agricultural vehicles are widely used in society, and the social supporting resources and maintenance parts are rich; Eighth, the whole machine has simple and compact structure and convenient maintenance. According to the above principles and prototype structure, large, medium and small series products can be formed according to the needs of different user groups, which has good market prospects. Compared with the traditional model, this model has obvious advantages such as low cost, less energy consumption, stubble cleaning and comprehensive utilization of straw, and has strong market competitiveness. At present, Huatai Machinery Research Institute is looking for partners, which can adopt various cooperation methods such as technology transfer or cooperative production.
