Description

Technical Field

[0001] This utility model relates to the field of straw treatment technology, and in particular to a straw composting and returning device. Background Technology

[0002] With the development of modern agriculture, crop yields have increased significantly, making agricultural waste disposal a pressing issue. Among these, the treatment of crop straw after harvest is particularly prominent. Traditional straw disposal methods mainly include burning and piling, which not only waste valuable biomass resources but also easily cause environmental pollution, such as air pollution and soil compaction.

[0003] In recent years, in response to the call for sustainable development and to promote green agriculture, the government and all sectors of society have actively advocated for the composting and returning of straw to the fields to increase soil organic matter content, improve soil structure, and promote crop growth.

[0004] However, in practice, some straw composting devices do not spray the microbial agent evenly onto the straw, resulting in insufficient composting and a reduced composting rate. Consequently, crops and soil cannot effectively absorb the nutrients from the straw, thus affecting the fertility of the straw when returned to the field. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the existing technology that the inoculant is not evenly sprayed onto the straw, resulting in insufficient straw decomposition and a reduced decomposition rate. Therefore, this invention proposes a straw decomposition and return-to-field device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A straw composting and returning device includes a connecting frame for connecting to an agricultural tractor, and further includes: a support base fixedly installed on the connecting frame; a mixing tank fixedly installed on the support base; and a spraying unit rotatably installed on the side of the connecting frame away from the agricultural tractor. A feed pipe is fixedly connected between the spraying unit and the mixing tank. The mixing tank contains a stirring component, which is connected to the spraying unit via a belt drive, causing the spraying unit to oscillate on the connecting frame.

[0008] To ensure uniform mixing of the medicine, preferably, the stirring component mainly includes a rotating shaft and a stirring paddle, the stirring paddle is horizontally mounted on the rotating shaft, and a motor is fixedly mounted on the mixing tank, the output end of the motor being connected to the rotating shaft via a coupling.

[0009] To loosen the soil and facilitate better penetration and mixing of the pesticide, the end of the rotating shaft away from the motor extends through the connecting frame and is fixedly mounted with a first harrow.

[0010] To expand the spraying range and ensure that the pesticide can be more evenly distributed in the field, the spraying unit mainly includes a crossbar, a U-shaped connecting rod, and a nozzle. The crossbar is rotatably installed below the connecting frame, and the U-shaped connecting rod is fixedly installed on the crossbar. A sliding pin is slidably installed on the U-shaped connecting rod, and the sliding pin is connected to the belt eccentric drive.

[0011] To facilitate disassembly and replacement of the nozzle, the nozzle further includes a clamping end with a locking bolt installed thereon, wherein the end of the feed tube furthest from the mixing tank is fixedly connected to the nozzle.

[0012] To ensure that the pesticide can penetrate deep into the soil and reduce waste caused by surface evaporation or runoff, a vertical shaft is rotatably mounted on the connecting frame. One end of the vertical shaft is connected to a belt drive, and a second harrow is fixedly mounted on the other end of the vertical shaft.

[0013] Compared with the prior art, this utility model provides a straw composting and returning device, which has the following beneficial effects:

[0014] 1. This straw composting and returning device uses a mixing component to mix the pesticide, ensuring that it is always in a uniform state. At the same time, the mixing component drives the spraying unit to swing through the belt drive, so that the spraying unit can cover a wider area during its movement, and evenly spray the pesticide onto the straw in the field to promote its rapid composting.

[0015] 2. In this straw composting and returning device, the first and second harrows work together. The former is responsible for deep tillage, while the latter focuses on loosening the surface soil. The combination of the two can achieve the best soil treatment effect and ensure that the pesticide can better penetrate into the soil. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0023] Example:

[0024] Reference Figures 1-4 A straw composting and returning device includes a connecting frame 1 for connecting to an agricultural tractor, using the power of the tractor's movement to drive the entire device. It also includes: a support base 2, fixedly mounted on the connecting frame 1; a mixing tank 3, fixedly mounted on the support base 2, for storing and mixing the composting agents or microbial agents required; and a spraying unit 4, rotatably mounted on the side of the connecting frame 1 away from the agricultural tractor. A feed pipe 5 is fixedly connected between the spraying unit 4 and the mixing tank 3 for spraying the agents from the mixing tank 3 onto the field. The mixing tank 3 contains a stirring component 6 for stirring the agents to ensure uniform mixing. The stirring component 6 is connected to the spraying unit 4 via a belt drive, allowing the spraying unit 4 to oscillate on the connecting frame 1 to cover a larger spraying area.

[0025] Before starting the operation, add the required pesticide or fungicide to the mixing tank 3 and start the agitator 6 to mix thoroughly. When the tractor moves, the connecting frame 1 moves the entire device, and at the same time, the agitator 6 continues to mix the pesticide to ensure that it is always in a uniform state. The agitator 6 drives the spraying part 4 to swing through the belt drive, so that the spraying part 4 can cover a wider area during the movement, and spray the pesticide evenly onto the straw in the field to promote its rapid decomposition.

[0026] The mixing component 6 mainly includes a rotating shaft 601 and a mixing blade 602. The mixing blade 602 is horizontally mounted on the rotating shaft 601. Preferably, the mixing blade 602 is designed with multiple blade-like structures, which can effectively cut and mix the agent, ensuring its uniform distribution. The shape and number of mixing blades 602 can be optimized and adjusted according to actual needs. A motor 603 is fixedly mounted on the mixing tank 3, and the output end of the motor 603 is connected to the rotating shaft 601 through a coupling.

[0027] When the motor 603 starts, its output end transmits power to the rotating shaft 601 through a coupling, which in turn drives the agitator 602 to rotate. During rotation, the agitator 602 cuts and mixes the reagents in the mixing tank 3, ensuring uniform mixing.

[0028] The end of the rotating shaft 601 away from the motor 603 passes through the connecting frame 1 and is fixedly installed with the first harrow 7.

[0029] As the rotating shaft 601 rotates, the first harrow 7 moves synchronously, loosening the soil and making it more porous, which is conducive to better penetration and mixing of pesticides.

[0030] The spraying unit 4 mainly includes a crossbar 401, a U-shaped connecting rod 402 and a nozzle 403. The crossbar 401 is rotatably installed below the connecting frame 1, and the U-shaped connecting rod 402 is fixedly installed on the crossbar 401. A sliding pin 404 is slidably installed on the U-shaped connecting rod 402, and the sliding pin 404 is connected to the belt eccentric drive.

[0031] When the mixing component 6, i.e. the rotating shaft 601, rotates, the sliding pin 404 is driven by the belt drive to move back and forth on the U-shaped connecting rod 402. Since the sliding pin 404 is eccentrically connected to the belt, this eccentric movement allows the spraying part 4 to swing with amplitude, expanding the spraying range and ensuring that the pesticide can be more evenly distributed in the field.

[0032] The nozzle 403 has a clamping end 405, on which a locking bolt 406 is installed, so that the nozzle 403 can be firmly fixed on the U-shaped connecting rod 402. The end of the material tube 5 away from the mixing box 3 is fixedly connected to the nozzle 403.

[0033] The nozzle 403 is fixed to the U-shaped connecting rod 402 by the locking bolt 406 on the clamping end 405. This design not only facilitates the disassembly and replacement of the nozzle 403, but also ensures that it remains stable during operation. The end of the material pipe 5 away from the mixing tank 3 is directly fixedly connected to the nozzle 403, ensuring the smoothness and reliability of the agent transmission.

[0034] A vertical shaft 8 is rotatably mounted on the connecting frame 1. One end of the vertical shaft 8 is connected to a belt drive, obtaining power from the mixing component 6 via the belt. A second harrow 9 is fixedly mounted on the other end of the vertical shaft 8 and operates as the vertical shaft 8 rotates. The design of the second harrow 9 is intended to further deepen and refine soil tillage, improving the mixing effect between the soil and the pesticide. It works in conjunction with the first harrow 7 to ensure that the pesticide can penetrate deep into the soil, reducing waste caused by surface evaporation or runoff, while also promoting soil loosening and aeration, which is beneficial to the development of crop roots.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
