Description

Technical Field

[0001] The invention relates to the technical field of agricultural equipment, in particular to a straw crushing, clearing and winding type residual film recycling machine. Background Art

[0002] Film-laying for crop cultivation helps conserve and increase soil moisture, raise ground temperature, and eliminate weeds and insects, ensuring early crop maturity, increased yields, and increased income for farmers. Therefore, thoroughly removing residual film from fields has become a key research topic. To address the problem of residual film in the soil and its contamination, agricultural machinery researchers in my country have developed a variety of residual film collection machines over the past few decades. However, the numerous uncertainties in the field after film-laying, such as soil specific resistance, soil moisture content, weathering of residual film from the previous crop, surface straw coverage, soil cover, and the season for film recovery, pose challenges to the development of residual film recovery machines. Furthermore, the film-wrapping roller of existing residual film recovery machines is an integrated design. Removing the residual film from the wrapping roller after recovery is time-consuming, labor-intensive, and inefficient. Summary of the Invention

[0003] In response to the above technical problems, the present invention provides a straw crushing and removing winding type residual film recovery machine, which can effectively solve the problem that the current residual film recovery machine cannot adapt to various working environments, and the removal of residual film is time-consuming and labor-intensive, and the labor intensity is high, resulting in the inability to carry out residual film recovery work efficiently.

[0004] In order to achieve the above object, the technical solution of the present invention is as follows:

[0005] The straw crushing and removing winding type residual film recycling machine includes a straw stubble destroying device, a reversing speed gear box is arranged in the front of the straw stubble destroying device, the reversing speed gear box and the power equipment are connected to each other, the straw stubble destroying device is connected to the reversing speed gear box, and a residual film winding and collecting device is arranged at the rear of the straw stubble destroying device, and the residual film winding and collecting device includes a frame, a winding device, a rotating frame, rake teeth and a film shovel, the frame is arranged at the rear of the straw stubble destroying device, a film shovel is arranged at the bottom of the front end of the frame, a rotating frame is arranged on the frame, and several winding devices are installed on the rotating frame, the winding device is connected to the reversing speed gear box, and several rake teeth are vertically arranged at the rear of the winding device, the rake teeth are fixedly mounted on the frame, and the rake teeth are wrapped and arranged on the rear side of the winding device.

[0006] A depth-limiting roller is installed between the straw stubble destroying device and the residual film winding and collecting device.

[0007] Two winders are arranged in the middle of the frame, and the two winders are arranged parallel to each other.

[0008] The winder is a cylindrical structure, and a plurality of detachable winder film teeth are radially arranged on the winder. The winder film teeth are rod-shaped structures with sharp heads. The winder consists of a conical cylinder I and a conical cylinder II. The large diameter end of the conical cylinder I is arranged on the rotating frame, and the small diameter end of the conical cylinder I and the small diameter end of the conical cylinder II are movably connected to each other by mortise and tenon joints.

[0009] A mounting hole is radially provided on the winder, a positioning assembly is provided in the mounting hole, the film tooth of the winder is fixedly provided in the mounting hole through the positioning assembly, the positioning assembly includes a mounting cylinder axially provided in the winder, one end of the mounting cylinder is closed, and the other end of the mounting cylinder is communicated with the mounting hole, a spring is provided inside the mounting cylinder, a top ball is provided at the end of the spring, and the top ball presses on the film tooth of the winder.

[0010] The straw stubble-chopping device includes a casing, a stubble-chopping roller is arranged at the front lower part of the casing, a spiral propeller is horizontally arranged inside the casing, the spiral propeller is located behind the stubble-chopping roller, the spiral propeller pushes the straw out from one side of the casing, and the reversing speed gear box is respectively connected to the spiral propeller and the stubble-chopping roller.

[0011] The horizontally arranged spiral propeller inside the casing is replaced by a throwing cylinder arranged on the top of the casing. The bottom of the throwing cylinder is communicated with the inside of the casing, and the top of the throwing cylinder is connected to the wind suction device.

[0012] The film scraping shovel is height-adjustable and comprises an equilateral trapezoidal mounting plate and a shovel plate. A plurality of the shovel plates are horizontally arranged on the lower surface of the equilateral trapezoidal mounting plate.

[0013] The horizontally arranged plurality of shovel plates are arranged in an undulating manner along the contour of the equilateral trapezoidal mounting plate.

[0014] The top of the rake teeth is fixedly mounted on a rake tooth connecting frame arranged on the upper part of the frame.

[0015] The beneficial effects of the present invention are:

[0016] (1) When the present invention moves in the field, the straw stubble-crushing device breaks up the surface stubble, straw, and weeds and transports them to the surface where the work has been done. The film-lifting shovel can adjust the depth of penetration into the soil according to the surface conditions, and lift up the surface soil, stubble, and residual film where the straw stubble-crushing device has worked. The surface soil, stubble, and residual film then fall down, keeping the surface soil, stubble, and residual film from adhering to each other. The rake teeth pass along the loosened shallow surface layer, and the loosened residual film is brought up and collected in front of the rake teeth. The winder arranged in front of the rake teeth rotates, and the residual film is rolled into a roll. The stubble, soil blocks, and broken straw are leaked from the middle of the rake teeth, completing the collection of the residual film. The present invention can adapt to various different surface working environments and has strong practicality. (2) In order to improve the residual film recovery efficiency and reduce the work intensity, the number of winders arranged inside the frame is two. The two winders are arranged in parallel with each other, and each winder is provided with rake teeth at the rear. (3) In order to improve the efficiency of film wrapping and film stripping, the winder is designed to be a cylindrical structure, and a mounting hole is set on the winder. The film teeth of the winder are inserted into the mounting hole. The film teeth of the winder are rod-shaped structures with sharp ends. When the winder rotates, the film teeth will be inserted into the residual film on the surface and the residual film will be completely attached to the winder. When removing the residual film, only the film teeth are removed, and then the mortise and tenon joints of the two conical cylinders are pulled apart to both sides. Since there is no obstruction of the film teeth, the residual film can be easily detached, which greatly facilitates the removal of the residual film from the winder and improves the efficiency of film wrapping and film stripping. (4) In order to improve the working efficiency of the straw stubble destroying device, the horizontal spiral propeller inside the casing is replaced with a throwing cylinder set on the top of the casing. The wind suction device connected to the top of the throwing cylinder is used to quickly suck the crops thrown by the stubble destroying roller out of the casing. (6) In order to improve the strength and working efficiency of the film-removing shovel, the working ends of the horizontally arranged shovel plates of the present invention are arranged along the contour of the equilateral trapezoidal mounting plate, so that the working ends of the shovel plates do not contact the ground surface at the same time, which can make the surface soil, stubble and residual film fall at different times after being arched and raised, further ensuring that the stubble, soil and residual film are not stuck together, thereby improving the residual film recovery efficiency.
