Description

Straw pulling and residual film recycling combined operation machine

technical field

The invention relates to a machine for pulling out straws and recovering residual film on the surface after harvesting crops, in particular to a combined operation machine for pulling out straws and recovering residual film.

Background technique

At present, agricultural plastic film mulching cultivation technology is widely used, and the use of plastic film cannot be recycled in time, causing serious pollution to the agricultural ecological environment. In order to solve the problem of residual film pollution, a variety of residual film recovery machines have been developed at home and abroad, which belong to straw crushing and returning to the field. There are 4JSM-1800 combined operation machine for residual film recovery and 4FS2 combined plastic film recovery machine for residual film recovery, and MSM-3 residual film recovery machine for seedling stage and MS-2 type plastic film recovery machine for residual film recovery. Corn seedling film harvesting machine, the models used for film harvesting after harvest include 1ZSM-800 residual film recycling machine, 4FS2 combined plastic film recycling machine and QS-2 residual film recycling machine. In addition, according to the working principle of the residual film picking mechanism, there are telescopic rod tooth type residual film recovery machines, spring tooth type stubble residual film recovery machines, gear tooth type residual film recovery machines, and tooth chain type residual film recovery machines.

The mulch film used in the year after crop harvest has a certain strength, and it is exposed in pieces on the ground surface. It is the best time to mechanically recycle the residual film. The covering soil fixes the residual film on the surface, which makes it difficult to recycle the residual film. The above straw crushing and returning to the field and residual film recycling combined operation machine can not effectively separate the crushed straw from the surface residual film to be collected, and the crushed straw stubble still affects the residual film recovery, and the recycling machine uses a "tooth" mechanism to directly recover the residual film , It is not easy to lift the residual film, the recovery rate of the residual film is low, and the recovered residual film contains a large amount of impurities. If the straw is uprooted and separated from the residual film on the surface, the residual film on the surface will no longer be bound by the root stubble, which is conducive to the recovery of the residual film. Therefore, it is of great significance to study a working tool with high operating efficiency, which can not only uproot straws but also recover residual film, to control farmland residual film pollution.

Contents of the invention

The object of the present invention is to provide a machine tool that can pull out straws and recover residual film in one operation. When the machine works, the straw is pulled up from the ground, and the straw is separated from the residual film, which is convenient for the recovery of residual film. The membrane is recovered cleanly and the recovered residual membrane contains less impurities.

The invention relates to a combined operation machine for straw pulling and residual film recovery, comprising a traction device, a transmission system, a frame, a residual film box, ground wheels, a straw pulling device and a residual film recovery device, characterized in that the traction device is arranged in front of the machine tool The straw pulling device is set on the rear side of the traction device, the residual film recovery device is set on the back or lower side of the straw pulling device, the residual film box is set on the rear side of the residual film recovery device, and the ground wheels and transmission system are set on the frame. , the straw pulling device is composed of a feeding chain rake, an upper straw pulling roller, a lower straw pulling roller, a scraper conveyor and a tail plate, and the above feeding chain rake is arranged in front of the upper straw pulling roller and the lower straw pulling roller side, the reel is set on the feeding chain rake, the upper stalk roller is set on the upper side of the lower stalk roller, the scraper conveyor is set on the rear side of the upper stalk roller and the lower stalk roller, and the tail plate is set on the scraper conveyor On the lower side of the upper end of the device, the residual film recovery device is composed of a film lifting roller, a film lifting shovel, a film lifting chain, a film picking tooth, a stripping wheel, a stripping blade and a stripping wheel shell, and the above film stripping roller is located at At the lower end of the film lifting chain, the film lifting shovel is set behind the lower side of the film lifting roller, the film picking teeth are set on the film lifting chain, the stripping wheel is set on the rear side of the upper end of the film lifting chain, and the stripping wheel shell is set around the stripping wheel On the outside, a plurality of stripping blades are arranged around the above-mentioned stripping wheel.

The feeding chain rake of the straw pulling device may be a reel.

The front side of the upper stalk pulling roller and the lower stalk pulling roller of the straw pulling device can be provided with a straw lifter.

The film removal roller may not be set on the described residual film recovery device.

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 and the implement of the present invention form a working unit, and the tractor can be driven by the above-mentioned transmission system The straw pulling device works, and the rolling of the ground wheel drives the residual film recovery device to work. During operation, the unit advances along the row of crop seedlings, and the feeding chain rake of the straw pulling device moves the upper end of the straw upright on the ground to the upward pulling roller and the lower pulling roller, and the upper pulling roller and the lower pulling roller rotate relatively, and the upper end of the straw Under the action of the upper stalk roller, it enters between the upper stalk roller and the lower stalk roller and is clamped. With the rotation of the upper and lower stalk rollers, the straw is continuously pulled between the upper and lower stalk rollers until the straw Pulled out from the surface soil, the pulled straw is transported to the upper end of the scraper conveyor by the scraper conveyor, and then the straw falls into the field along the tail plate under the action of gravity. At the same time, the film removal roller of the residual film recovery device rolls on the surface where the straw is pulled out, and the film removal shovel scoops up the surface residual film and a certain thickness of surface soil, and the scooped-up film and soil mixture move backward along the film removal shovel , and finally fall on the film-lifting chain, the film-picking teeth on the film-lifting chain hook the residual film, and move upward with the film-lifting chain, and the soil or straw and other sundries mixed in the residual film will be lifted from the film under the action of gravity Scattering on the chain, when the residual film is transported to the stripping wheel on the upper side of the film chain, the residual film will fall into the residual film box under the action of the stripping blade of the stripping wheel. The depth of entry into the soil of the film shovel can be adjusted by adjusting the up and down positions of the film film shovel and the film film shovel.

The invention has the advantages of simple structure, high operation speed, good ground profiling, clean residual film recovery and less impurity in the recovered residual film, and can meet the requirements of straw plucking and residual film recovery.
