Description

Cotton boll residual film recovery and cotton stalk crushing and returning to the field combined operation machine

technical field

The invention relates to a combined operation machine for recovering cotton boll residual film and crushing and returning cotton stalks to the field.

Background technique

Xinjiang has unique climatic conditions and a large scale of cotton planting. It is the main production base of high-quality cotton in my country. Large-scale cotton planting generally adopts mulching technology. The use of a large number of plastic mulches has caused serious white pollution of farmland, which has a serious impact on cotton germination, growth and cotton production, which is not conducive to the sustainable development of farmland. After the cotton is harvested, there are still some bolls on the cotton plants, which affect the recovery rate of mechanically recovered residual film.

Cotton has been planted for a long time in Xinjiang, and the accumulation of residual film in cotton fields is serious. It is urgent to control the pollution of residual film in cotton fields. The presence of bolls on cotton plants after cotton harvest provides a good source of feed for cattle and sheep. Adding the cotton boll recycling process before the residual film recovery operation of the traditional residual film recycling machine can not only maximize the rational use of resources but also reduce the impact on the recovery of residual film. Studies have shown that crushed cotton stalks can help improve soil organic matter content and soil improvement.

Contents of the invention

The purpose of the present invention is to provide a combined operation machine for recovering cotton boll residual film and crushing cotton stalks, which can integrate the functions of cotton boll recovery, residual film recovery, and cotton stalk crushing and returning to the field, so as to reduce the number of operations of agricultural machinery in the field and improve The use efficiency of agricultural machinery can reduce the maintenance cost of agricultural machinery. It is safe, reliable, reasonable in structure, high in operation efficiency, and stable in operation quality. The recovered cotton bolls can be eaten by cattle and sheep, the recycled residual film has a low impurity rate, and the cotton stalks are crushed and returned to the field. stable quality.

The purpose of the present invention is achieved in this way. A combined operation machine for recovering cotton boll residual film and crushing cotton stalks for returning to the field includes a frame. A depth-limiting wheel is respectively installed on both sides of the front end of the frame. The machine between the two depth-limiting wheels A comb-toothed boll recovery shovel is horizontally installed under the frame, and a boll recovery box is connected to the rear of the boll recovery shovel. The outlet at the lower end of the tee extends into the boll collection box on the top surface of the frame. A drive sprocket shaft is horizontally arranged under the frame behind the boll recovery box. The middle part of the frame and the rear top surface The transition sprocket shaft and the driven sprocket shaft are arranged horizontally on the top, and the conveyor chains are respectively arranged on the sprockets on both sides of the three sprocket shafts. The film-picking tooth support plates are evenly spaced horizontally between the two conveyor chains. The tooth support plates are vertically evenly spaced and fixed to the film-picking teeth. An auxiliary film delivery plate is installed obliquely under the frame behind the driving sprocket shaft. Cotton stalk crushing and returning device, cotton stalk crushing and throwing knives are evenly distributed on the rotating shaft of the cotton stalk crushing and returning device, a film collecting box is arranged under the frame behind the cotton stalk crushing and returning device, and the machine behind the film collecting box There are traveling wheels on both sides of the bottom of the frame, and a film-removing roller brush is installed horizontally above the rear end of the frame. The rotation is driven by a tractor.

When the present invention works, the frame is suspended and connected with the tractor's traction device through a three-point suspension device, and the power output shaft of the tractor is connected with the power input shaft of the transmission device of the present invention through a transmission shaft, thereby forming a combined operation unit. The tractor transmits power through the transmission device to drive the comb-type cotton boll recovery device, the driving sprocket shaft, the cotton stalk crushing and returning device, and the film-removing roller brush to work. During the working process, the unit moves forward at a constant speed along the cotton field seedling row, and the comb-toothed boll recovery shovel strokes the bolls and cotton leaves on the cotton stalks, and the bolls and cotton leaves are continuously entered during the forward movement of the machine. Cotton boll recovery hopper, the bolls and cotton leaves in the boll recovery hopper are transported to the tee along the conveying hose under the suction force generated by the negative pressure fan, and the bolls and cotton leaves in the tee are installed on the side of the tee close to the negative pressure fan Under the blocking effect of the blocking screen, it enters the boll collection box along the three-way outlet connected with the inlet of the boll collection box, thereby realizing the boll recovery operation. When the machine is moving forward, the transmission device drives the driving sprocket shaft through the chain transmission to drive the conveying chain to carry out the residual film recovery operation. During the operation, the film picking teeth at the bottom of the machine continuously pick up the residual film on the surface and transport the residual film to the The auxiliary film conveying plate, with the help of friction between the film picking teeth, residual film, and film conveying auxiliary plate, conveys the residual film to the top of the film collecting box, most of the remaining film falls into the film collecting box under the action of gravity, some Due to the sticky soil on the film picking teeth, the residual film does not fall into the film collecting box, and the film stripping roller brush produces non-stop rotating motion under the action of the transmission device, and removes the residual film that has not fallen from the film picking teeth from the film picking teeth When the upper brush is down, by adjusting the two depth-gauge wheels in front of the machine frame, the depth of the film picking teeth at the bottom of the machine can be controlled, so as to control the strength of residual film recovery, and the whole process can realize the recovery of residual film. Cotton stalk crushing and returning device Under the action of the transmission device, the cotton stalk crushing knife rotates continuously at high speed to crush the upright cotton stalks into short pieces. Complete the efficient crushing and returning of cotton stalks to the field, and at the same time adjust the two depth-limiting wheels in front of the frame to control the height of cotton stalk residues after the cotton stalks are crushed. The combined operation machine composed of tractors and implements completes the three operations of cotton boll recovery, residual film recovery, and cotton stalk crushing and returning to the field in one operation.

The invention has the advantages of compact structure, strong practicability, high operation efficiency and stable operation quality, and can complete the operations of boll recovery, residual film recovery and cotton stalk crushing and returning to the field in one operation. Recycled cotton bolls can be used as feed for cattle and sheep, with a high recovery rate of residual film, low impurity content of recycled residual film, and controllable degree of cotton stalk crushing. It is suitable for the combination of cotton boll recovery, residual film recovery and cotton stalk crushing and returning to the field under the cotton planting mode in Xinjiang Operation.
