Description

Technical Field

[0001] The present application belongs to the technical field of straw crushing and returning to the field, and in particular relates to a straw crushing and returning to the field device. Background Art

[0002] Straw crushing and returning to the field refers to an agricultural technology in which the straw remaining after crop harvest is mechanically crushed and then directly pressed or covered into the soil. This practice can increase soil organic matter, improve soil structure, and increase soil permeability and water retention capacity, thereby promoting the development of crop roots and microbial activity, and helping to improve soil fertility and crop yields.

[0003] The existing utility model with authorization announcement number CN220693671U discloses a corn straw crushing and returning device to the field, including a shell, a power transfer assembly fixedly installed on the top of the shell, the power transfer assembly is connected to the output end of the external agricultural machinery, an inclined surface is provided on the right side of the shell, a first mounting seat is fixedly installed on the inclined surface, a blocking plate is fixedly installed on the right side of the shell, and four groups of plows for turning over the soil are arranged in an array at the bottom of the blocking plate.

[0004] By adopting the above technical solution, the soil clods inside the soil are broken up by the soil-planing roller, the crushed powder and soil are fully mixed, and finally the mixed land is leveled by the provided leveling roller, which can promote soil decomposition. When cultivating, there is no need to additionally turn over the soil, dig out the roots, and level the land, which is more convenient. However, in the process of using the above technical solution, although the standing straw can be pushed to a part by the field returner, the pushed straw will still be at a certain height from the ground. The taller straw is not easy to mix with the soil after being crushed. At the same time, the taller straw may also accumulate at the feeding inlet of the field returner, which may cause the machine to be blocked, and will also have a certain impact on the crushing quality of the straw, affecting the crushing efficiency of the device, and thus leading to the problem of poor practicality.

[0005] To this end, we proposed a straw crushing and returning device to the field to solve the above problems. Utility Model Content

[0006] The purpose of this application is to solve the problem in the prior art that the distance between straw and the land is large, resulting in low crushing efficiency and difficulty in mixing with the soil, and to propose a straw crushing and returning device to the field.

[0007] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0008] The lifting of the lifting of the lifting of the lifting of the lifting plate is increased, and the lifting of the lifting plate is increased in number and the amount of lifting of the lifting plate is increased.

[0009] Preferably, a mounting bracket is fixedly connected to the upper surface of the shell, and a limit pin is threadedly connected to the inner wall of the mounting bracket.

[0010] Preferably, the outer surface of the shell is rotatably connected to two fixing frames, and the inner walls of the two fixing frames are jointly rotatably connected to a leveling roller.

[0011] Preferably, six reinforcement blocks are fixedly connected to the right side of the fixing plate, and the bottom surface of each reinforcement block is fixedly connected to the upper surface of the support plate.

[0012] Preferably, a rotating motor is fixedly connected to the upper surface of the housing, and an output end of the rotating motor power is fixedly connected to a rotating shaft.

[0013] Preferably, a fixed cover is fixedly connected to the outer surface of the rotating motor, a bottom surface of the fixed cover is fixedly connected to the upper surface of the outer shell, and a cover plate is slidably connected to the inner wall of the fixed cover.

[0014] Preferably, a crushing roller is provided below the rotating motor, and the outer surface of the crushing roller is rotatably connected to the inner wall of the shell.

[0015] Preferably, two gears are provided on the outside of the crushing roller, wherein the inner wall of one of the gears is fixedly connected to the outer surface of the crushing roller, and the inner wall of the other gear is fixedly connected to the outer surface of the rotating shaft, and the outer surfaces of the two gears are meshed with a toothed synchronous belt.

[0016] In summary, the technical effects and advantages of this application are:

[0017] 1. By setting the fixing plate, the supporting plate, the first combing plate and the second combing plate, the first combing plate can push a part of the straw with a higher height during the movement, and the second combing plate can further push the straw pushed by the first combing plate, so that the straw can be lying on the surface of the ground, which is convenient for entering the shell through the feeding port, and also convenient for subsequent crushing work;

[0018] 2. By setting a fixed frame, a support frame, a flattening roller, a connecting column, a limiting cylinder and a spring, the support frame can provide a good limiting effect for the flattening roller. At the same time, the flattening roller can further crush the fallen straw to prevent the straw from standing up again after the second combing plate passes. The connecting column, the limiting cylinder and the spring can facilitate the flattening roller to move up slightly during rolling, so that it can roll more smoothly, thereby effectively avoiding the impact of high straw height on crushing efficiency and quality, and improving the mixing of crushed straw and soil.

By providing the reinforcement blocks 17, the firmness of the fixed plate 3 can be further increased to avoid separation during use.

[0028] The inner wall of the outer shell 1 is fixedly connected to a fixed frame 16, the inner wall of the fixed frame 16 is slidably connected to a support frame 20, the upper surface of the outer shell 1 is fixedly connected to a rotating motor 10, and the output end of the power of the rotating motor 10 is fixedly connected to a rotating shaft 11. By setting the rotating motor 10 and the rotating shaft 11, the power required for crushing can be provided, thereby quickly carrying out the straw crushing work.

[0029] The inner wall of the support frame 20 is rotatably connected to a flattening roller 21, the upper surface of the support frame 20 is fixedly connected to seven connecting columns 22, the outer surface of the rotating motor 10 is fixedly connected to a fixed cover 6, the bottom surface of the fixed cover 6 is fixedly connected to the upper surface of the outer shell 1, and the inner wall of the fixed cover 6 is slidably connected to a cover plate 7.

At the same time, the cover plate 7 is fixed by bolts, and a dust cover is fixed inside the cover plate 7 to prevent dust from entering the interior of the rotating motor 10.

[0030] The outer surface of each connecting column 22 is slidably connected to the limiting cylinder 23. By setting the limiting cylinder 23 and the fixed frame 16, the inner wall of the fixed frame 16 has a certain curvature, so a part of the limiting cylinder 23 is fixed on the inclined surface of the fixed frame 16, and the limiting cylinder 23 can play a certain limiting role. The outer surface of each limiting cylinder 23 is fixedly connected to the inner wall of the outer shell 1. A crushing roller 14 is provided below the rotating motor 10.

After that, the staff fixes the device behind a tractor or other driving machinery through the mounting bracket 4 and the limit latch 5, and then performs the straw crushing and returning work. When performing the straw crushing and returning work, first turn on the rotating motor 10. After the rotating motor 10 is turned on, it can generate power rotation. The rotating motor 10 can drive the rotating shaft 11 and a gear 12 to rotate, and then it can drive the toothed synchronous belt 13, another gear 12 and the crushing roller 14 to rotate, thereby facilitating the straw crushing work. The first combing plate 15 can push a part of the straw with a higher height during the movement, and then the device continues to move forward. At the same time, the second combing plate 19 can further push the straw pushed by the first combing plate 15, so that the straw can be fallen on the surface of the ground, which is convenient for entering the shell 1 through the feeding port. The plow 18 of the device can turn the soil up for easy mixing with the crushed straw, and then the flattening roller 21 can further crush the fallen straw to prevent the straw from standing up again after the second combing plate 19 passes.
