Description

Technical Field

[0001] This utility model relates to the field of acidified farmland remediation technology, specifically to an acidified farmland remediation spreading device. Background Technology

[0002] The core hazards of soil acidification include damaging soil structure, inhibiting plant root development, reducing nutrient availability, increasing heavy metal toxicity, reducing microbial activity, and exacerbating pests and diseases, ultimately leading to reduced crop yields and lower quality. Soil acidification must be remedied, typically by applying alkaline substances such as lime, smoky manure, and organic fertilizers to the soil.

[0003] Soil acidification typically occurs over large areas, making manual application of neutralizing materials insufficient. Large-scale treatment of soil acidification requires the use of spreaders to apply neutralizing materials. For example, a solid fertilizer spreading device, as described in paragraph

[0029] of the specification, involves moving the hopper using wheels, starting a second motor to rotate a first sprocket, which in turn rotates a conveyor chain, which in turn rotates a second sprocket, moving the fertilizer to the crushing assembly. A third motor then rotates a first crushing roller, which in turn rotates a first gear. The meshing of the first and second gears rotates a second crushing roller, crushing the solid fertilizer. Finally, the first motor rotates a spreading wheel, which spreads the fertilizer, thus achieving thorough crushing and spreading of the solid fertilizer. The current method involves spreading fertilizer using a motor-driven spreading wheel. However, the motor requires a continuous power supply, which becomes a problem for large-scale soil treatment and is unsuitable for such operations. Therefore, we propose a fertilizer spreading device for acidified farmland remediation. Utility Model Content

[0021] The technical solution of this utility model will be clearly and completely described below with reference to its embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] Reference Figures 1 to 4 This utility model provides a technical solution: an acidified farmland treatment spreading device, including a frame 6, with spring plate shock absorbers 11 respectively provided on the bottom of both sides of the frame 6, and an axle 20 provided below the spring plate shock absorbers 11, that is, the two spring plate shock absorbers are connected through the axle 20, and a traveling wheel 8 is rotatably installed at both ends of the axle 20, and the traveling wheel 8 is located on both sides of the frame 6. The spring plate shock absorbers 11 have a large supporting force and can effectively and stably support the frame 6. A material container 1 is located on the top of the frame 6. Multiple supports 7 are located between the material container 1 and the frame 6 on both sides. A discharge channel 15 is located at the bottom of one end of the material container 1. For example... Figure 1 As shown, a connecting frame 3 is installed at the end of the frame 6 away from the discharge channel 15. The end of the connecting frame 3 is provided with a pin hole. The connecting frame 3 is used to connect with the trailer (agricultural machinery), so that the trailer can drive the frame 6 to travel in the field. The spring plate shock absorber can play a certain role in shock absorption.

[0023] Corresponding to the discharge channel 15, a spiral shaft 2 is provided at the bottom of the material holding box 1. The two ends of the spiral shaft 2 are rotatably connected to the material holding box 1. When the spiral shaft 2 rotates, it can drive the material in the material holding box 1 to be continuously discharged from the discharge channel 15. Corresponding to acidic soil, the material in the material holding box 1 is alkaline, such as lime powder, alkaline organic fertilizer or alkaline soil, etc. The material falls from the discharge channel 15 onto the acidic soil.

[0024] In this application, a spreading disc 10 is provided below the discharge channel 15. The spreading disc 10 and the spiral shaft 2 move synchronously and are simultaneously driven to rotate by the trailer. The specific driving structure is shown below: like Figure 4 As shown, the end of the spiral shaft 2 furthest from the discharge channel 15 is connected to the first T-shaped commutator 4 via the third universal joint 19. The first T-shaped commutator 4 is connected to the frame 6 and is installed at one end of the frame 6. For example... Figure 4 As shown, the spreading disc 10 is installed on the top of the second T-type commutator 9. The spreading disc is connected to the top of the second T-type commutator 9 through a flange, which is located on the top of the shaft of the second T-type commutator 9. The second T-type commutator 9 is connected to the frame 6. The second T-type commutator 9 is mounted at the other end of the frame 6. The second T-type commutator 9 is connected to the frame 6 via a transmission mechanism. Figure 4 As shown, the transmission mechanism includes a second universal joint 16 connected to the second T-type commutator 9. The other end of the second universal joint 16 is connected to the drive shaft 18. The other end of the drive shaft 18 is connected to the first T-type commutator 4. The drive shaft 18 is rotatably mounted under the frame 6. Specifically, at least two support seats 17 are rotatably mounted on the drive shaft 18. The support seats 17 are mounted under the frame 6. Specifically, the first T-shaped commutator 4 is equipped with a first universal joint 5 at the end away from the discharge channel 15. In actual use, the first universal joint 5 needs to be connected to the drive shaft of the trailer. So when the trailer drives the first universal joint 5 to rotate, the first universal joint 5 drives the third universal joint 19 and the drive shaft 18 to rotate simultaneously through the first T-shaped commutator 4. The third universal joint 19 can drive the spiral shaft 2 to rotate, so that the material of the spiral shaft 2 is discharged from the discharge channel 15. The drive shaft 18 will drive the second T-shaped commutator 9 to rotate through the second universal joint 16. The second T-shaped commutator 9 can drive the spreading disc 10 to rotate rapidly. Therefore, in this application, the spiral shaft 2 and the spreading disc 10 are driven to rotate simultaneously by the trailer without the need for additional power. like Figure 2 As shown, in order to throw the material out faster, multiple arc-shaped ridges 12 are symmetrically arranged on the top of the spreading disc 10. In order to prevent the material from being thrown into the frame 6, the side of the spreading disc 10 closest to the frame 6 is located inside the arc-shaped baffle 13. The arc-shaped baffle 13 is set on the frame 6. So, under the rotation of the spreading disc 10, the material is scattered in a fan shape behind the frame 6, and the spreading area is large and uniform.

[0025] Based on the above embodiments, further optimizations can be made, such as... Figure 2 As shown, a pull plate 14 is movably inserted into the top of the discharge channel 15. The pull plate 14 can seal or open the discharge channel 15. When transporting materials, the pull plate 14 can be inserted into the discharge channel 15 to prevent a small amount of material from leaking out.

[0026] Based on the above embodiments, it should be further explained that the T-type commutator is also called the T-series steering box or the T-type bevel gear steering box. It contains two vertically meshing bevel gears. Therefore, in actual use, the size of the bevel gears in the commutator can be changed to achieve different transmission ratios, thereby allowing the spiral shaft 2 and the spreading disc 10 to achieve different speed requirements. After the spreading disc 10 spreads the material onto the surface of acidic soil, the soil can be tilled once by a rotary tiller to fully mix the material with the acidic soil.

[0027] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
