Working principle of corn combine harvester

The 4YW-Q corn harvester developed and produced by Tianjin Fukang Agricultural Development Co., Ltd. for many years has passed the appraisal of the Ministry of Agriculture and obtained 2 national patents. This machine can harvest corn at any planting row spacing within the designed cutting width range, and can harvest corn without rows. At the same time, it can crush the stalks and return them to the field or for silage. This machine is matched with Tieniu 55C, 60, 650, JDT600, JDT654, JDT720, JDT724, JDT800, JDT804, Foton 70 series, Dongfanghong 70 series tractors, and can also be used with self-propelled grain harvesters to replace corn headers, thereby increasing Machine utilization. This machine has the characteristics of scientific and reasonable overall machine design, simple mechanism, high strength, convenient operation, flexibility and high production efficiency. The straw crushing and returning part adopts a light working principle, with low power consumption, self-sharpening tools, good crushing effect and long service life. The machine has good passability during the harvesting process, with no broken stems, no clogging, and low impurity content. The grain loss rate, ear loss rate, and grain damage rate are all lower than the national standard.

In 2004, it was designated as the "National Key Promotion Plan for Scientific and Technological Achievements" by the Ministry of Science and Technology.

A new principle The compound corn combine harvester was successfully developed

In recent years, the development, production, promotion and application of corn combine harvesters have always been a hot spot in agricultural mechanization, attracting many scientific research institutions and production enterprises. According to incomplete statistics, by the end of 2000, there were more than 60 companies in my country that had developed corn combine harvesters, with more than 20 types of products and more than 80 models. However, due to the complexity of my country's corn planting and harvesting methods, the limitations 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 work efficiency, Problems such as poor straw crushing effect and the inability to process the stubble at one time have made corn harvest a "bottleneck" restricting the development of agricultural mechanization in our country. Now, after three years of hard exploration and unremitting efforts, a new compound corn combine harvester based on the utilization of the whole corn straw, with a new breakthrough in working principle, and has obtained three national patents (one of which is an invention patent) has been launched in Shandong Province. Qingzhou Huatai Machinery Research Institute successfully developed it. Compared with the currently promoted corn combine harvester, it is completely free from the constraints of traditional principles, has a unique and innovative structural design, and pioneers the use of the entire corn straw. Its main performance can be summarized as three major innovative breakthroughs and eight unique advantages. Three major innovative breakthroughs: First, innovative breakthroughs in working principles. Different from the traditional principle, the operation process of this machine is: self-clearing the path to pull out the whole corn plant → the root stubble is lifted off the ground and the rotary knife removes the root soil → the whole plant is transported to the picking roller → the ears are picked, and then divided into two roads, one road One is ear lifting → header → hydraulic lifting and unloading of grain in the header; the other is post-conveying and separation of straw → straw juice extraction, followed by juice collection or spraying and returning to the field, straw crushing and returning to the field or straw residue collection, etc. . The second is an innovative breakthrough in the comprehensive development and utilization of straw. This machine can extract corn straw juice used as livestock and poultry feed and fertilizer for flowers, fruits and vegetables. The straw residue after juice extraction and crushing is easy to collect and utilize. Especially when used in pulp production, it can reduce environmental pollution during the production process. The third is an innovative breakthrough in corn stubble treatment. This machine completely solves the root problem of stubble that troubles farmers and saves them one stubble-breaking operation.

Eight unique advantages: First, it consumes less power, saving about 40% of power compared with traditional models; second, the straw is chopped inside the machine, and the effect is good; third, it adopts a vertical combination of counter-rolling ear picking rollers, which is small in size and light in weight. The ear picking effect is good and the harvest loss is small; fourth, the ear lifting mechanism also has the function of removing debris; fifth, the ear collection box is hydraulically lifted and then tilted to unload grain. The mechanism is light and practical, and the lifting height is adjustable, which greatly facilitates grain unloading. , saving the time of unloading grain; Sixth, extensive use of chain and belt transmission, using a unique chain box to replace the traditional gear box, simplifying the structure, reducing the cost, and facilitating maintenance; Seventh, widely using the large number of items in the society There are mature parts and components for small four-wheel tractors and three-wheel agricultural vehicles, and there are abundant social supporting resources and repair parts. Eighth, the structure of the whole machine is simple, compact, and easy to maintain. Based on the above principles and drawing on the prototype structure, large, medium and small series products can be formed according to the needs of different user groups, with good market prospects. Compared with traditional models, this model has significant advantages such as low cost, low energy consumption, stubble removal, and the ability to separate and comprehensively utilize straw, making it highly competitive in the market. Currently, Huatai Machinery Research Institute is seeking partners, which can adopt various cooperation methods such as technology transfer or cooperative production.
