Description

A combined operation machine for straw crushing and returning to the field and residual film recovery

technical field

The invention relates to a machine for crushing and returning farmland crop straws to the field and recovering residual film on the surface, in particular to a combined operation machine for crushing and returning straws to the field and recovering residual film. the

Background technique

At present, due to the large-scale promotion and use of plastic film cultivation technology, farmland is seriously polluted by residual film. In order to solve the problem of residual film pollution, a variety of residual film recovery machines have been developed at home and abroad. 4JSM-1800 Residual Film Recycling Combined Operating Machine and 4FS2 Plastic Film Recycling Machine are only used to recycle residual film. There are MSM-3 Residual Film Recycling Machine at Seedling Stage and MS-2 Residual Film Recycling Machine for Corn Seedling Stage, which are used for harvesting After harvesting, there are 1ZSM-800 residual film recovery machine, 1MC-70 plastic film recovery stubble machine, 4FS2 combined plastic film recovery machine and QS-2 residual film recovery machine. The machines used for soil preparation and residual film recovery before sowing include ISM -5 type close-packed elastic teeth residual film recovery machine. In addition, according to the working principle of the residual film picking mechanism, there are telescopic rod tooth type residual film recovery machines, shovel type stubble residual film recovery machines, gear tooth type residual film recovery machines, and tooth chain type residual film recovery machines. the

The above straw crushing and returning to the field and residual film recovery combined operation machine mainly use vertical axis type slinger or horizontal axis type slinger to crush straw, and use "shovel type" or "tooth type" mechanism installed in front of residual film box to recover residual film. This kind of operation method has high energy consumption for crushing straw, and the operation speed of residual film recovery is low, and the operation speed of straw crushing is high. The speed of the two does not match, resulting in a decrease in the operation efficiency of the whole machine, and the residual film is easy to wrap around the working parts of the film. After the crops are harvested, it is the best time to recycle the residual film. Due to the presence of straw in the field, it is difficult to simply recycle the residual film. Therefore, it is of great significance to develop a combined operation machine with high efficiency that can crush the straw and return it to the field and recycle the residual film. . the

Contents of the invention

The purpose of the present invention is to provide an operating tool with high operating speed and low energy consumption, which can crush straw and return it to the field and recover residual film. the

The invention relates to a combined operation machine for straw crushing and returning to the field and residual film recovery, which includes a traction device, a transmission system, a frame, a residual film box, ground wheels, loose soil rod teeth, a straw crushing device and a residual film recovery device. The straw crushing device is arranged in front of the residual film box, and the straw crushing device is composed of a reciprocating cutter, a transverse conveyor belt, a disc cutter, a shield and a transmission device, and the reciprocating cutter is installed in the straw crushing device. The bottom of the horizontal conveyor belt is above the above-mentioned reciprocating cutter, and a disc-type chopper is provided on one side of the horizontal conveyor belt. On the outside of the above-mentioned disc-type chopper, the residual film recovery device is arranged behind the residual film box, one end is connected to the upper side entrance of the residual film box, and the other end is in contact with the ground. , a bottom plate and a profiling wheel, the above-mentioned sprocket rake has a tooth bar, the film-holding spring teeth are arranged on the rear side of the end of the residual film recovery device in contact with the ground, and the bottom plate is on the lower side of the sprocket rake , there is a certain gap between the bottom plate and the above-mentioned gear rod, and the above-mentioned ground profiling wheel is installed on the lower side of the end of the residual film recovery film device in contact with the ground. When working, the profiling wheel contacts the ground and supports the lower end of the residual film recovery device. The ripper rod teeth of the ripper are arranged on the front part of the residual film box. the

The disc cutter head of the disc chopper can be a disc saw blade or a rotary blade. the

There may be multiple teeth of the loosening rod. the

The working process of the present invention is as follows: the tractor is connected with the implement of the present invention through the traction device, the power output shaft of the tractor is connected with the transmission system of the implement of the present invention through the transmission shaft, and the tractor can drive the straw crushing device and the residual film recovery device to work through the above transmission system , the tractor and the tool of the present invention form a working unit. During operation, the unit advances along the row of crop seedlings, and the reciprocating cutter at the bottom of the straw crushing device cuts off the crop straw from the root, and the cut crop straw is transported to the side of the straw crushing device near the disc cutter by the horizontal conveyor belt. The high-speed rotating blade on the disc chopper cuts and pulverizes the delivered crop stalks, and under the shielding effect of the shield, the chopped stalks fall to the side of the working unit, and at the same time, the teeth of the loosening rod dig loose and press on the For soil clods on the residual film, the transmission system drives the residual film recovery device to work, the sprocket rake on the residual film recovery device rolls, and when the tooth bar on the sprocket rake continuously rotates through the ground in sequence, the residual film on the ground is picked up and picked up. The residual film picked up is transported to the residual film box in the gap between the gear bar and the bottom plate, and the residual film missed by the gear bar on the ground can be picked up by the film-holding elastic teeth and transported to the residual film box through the sprocket rake. By adjusting the height of the profiling wheel, the distance between the gear rod and the ground can be adjusted to achieve the purpose of adjusting the strength of the film. the

The invention has the advantages of high operating speed, clean recovery of residual film, low energy consumption, separation of membrane rods, and difficulty in winding working parts with residual film, and can meet the requirements of crushing straw and recovering residual film. the
