s road sign" 4YZ-3 self-propelled corn glutinous rice with harvest l Zhang Weijun Meng Jianhua-3 self-propelled corn combine harvester is a corn harvesting machine jointly developed and designed by the Zhongcheng Yucheng Combine Harvester Factory and Ukraine. (See the color insert ad for this issue). It directly introduces the harvesting parts such as the picking table, the ear conveying device and the straw pulverizer of the KCKY series corn combine harvester produced by the internationally advanced Kherson Kangbyin Co., Ltd., and adopts the harvesting and harvesting machine. The reliable power, chassis, walking, hydraulic, electrical and other components of the plant have been properly configured to complete the three-row corn picking, collecting box and straw crushing and returning to the field. After expert appraisal, the performance of the whole machine has reached the international advanced level and was recognized as the “2001 Key New Product†by the State Economic and Trade Commission. The slope of the farmland is not more than 8 degrees, the moisture content of the grain is not more than 30%, the lodging rate of the plant is not more than 5%, the sagging rate of the ear is not more than 15%, and the height of the lowest ear is not less than 35 cm, which can be harvested normally. 82.5kW harvest row number 3 rows grain loss rate at 2% ear loss rate 矣3% This machine is mainly composed of chassis part, power part, picking table part, elevator part, ear box part, straw pulverizer part, hydraulic part , the bridge part and the electrical parts are composed. The structure and performance of the main part of the machine are briefly described as follows: The picking table is composed of a picking device, a screw conveyor, a transmission device, a cover plate and a guard device. The picking device includes a pulling stem roll, a picking plate, a feeding chain, a transfer box and a remover for picking up the corn ears and delivering the picked ears to the ear screw conveyor. The spiral conveyor of the ear consists of welded pipes, blades and dials. During operation, the harvester travels along the erect corn row, and the corn stalk with the ear is guided by the stalk supporter and is fed by the feeding chain into the powder picking device, and then a pair of reversely rotating puller rolls Pulling the corn stalk through the working gap of the picking board, the ear is removed due to the large diameter and can not be removed through the picking gap, and is sent to the ear screw conveyor by the chain with the plucking board, and then enters the corn combine harvester. Ear conveyor. The picking table cover can directionalally flow the stems and ears, and prevent the stalk fragments and debris from obstructing the picking device. The lift section includes a conveyor chain, a cover, a movable cover, a fan, a straw eliminator, a drive shaft and an outer casing. The effect is to transport and pour the ears from the ear screw conveyor into the ear box. The fan is used to separate the lighter dopants (leaves, mink, stalk skin) in the ear between the lift section and the ear box. The straw cull is used to exclude the stalk leaves contained in the ear by the lifting device, and the dopant separated by the fan is secondarily chopped. The part of the ear box is a flip type box that can be directly unloaded onto the transport vehicle by hydraulically tilting back 135°. Part of the straw pulverizer is to directly smash the stem after picking the ear and throw it back into the field. The hydraulic part consists of two parts, steering and steering. The steering part is used to control the steering of the steering wheel, and the steering part is used to control the picking up, the straw shredder lifting, the clutch disengagement of the main clutch, the tipping of the ear box, and the stepless shifting of the walking. The chassis part is composed of a frame, a walking continuously variable transmission system, a drive wheel bridge, a steering wheel bridge and the like. The walking continuously variable transmission system is located on the left side of the machine, which uses a two-stage belt ratio to achieve stepless speed change. The drive axle is composed of a gearbox with a clutch and a differential, a side reducer and the like. The steering wheel axle is handed over to the rear pipe beam of the body, and is guided by different terrains and road conditions. (1) The engine with bidirectional output is selected as the power mechanism, and the main power and the traveling power are operated separately, the power transmission is reliable, and the work is stable. (2) The picking device adopts the world's advanced pull-roller structure, which is reliable in picking and has little loss of ear and grain. (3) The straw crushing motor knife adopts the world's advanced “self-sharpening†material and wear-resistant spraying technology. The tool keeps the tough and sharp, and the wear is very small, which effectively ensures the straw shredding performance and greatly reduces the crushing. Power consumption. (4) The ear box is hydraulically flipped to unload the grain, which is easy to operate and convenient.
