Description

Technical Field

[0001] This utility model relates to the field of agricultural fertilizer spreading technology, specifically to a disc-type fertilizer spreading mechanism. Background Technology

[0002] Disc-type fertilizer spreaders are used for large-scale application of base fertilizer to farmland crops. They are used to spread a large amount of fertilizer evenly on the soil surface before or at the same time as sowing, and then mix the fertilizer into the soil through plowing or rotary tillage.

[0003] However, when using a disc fertilizer spreader for fertilizer application, the fertilizer needs to be pre-treated. When the fertilizer has a high moisture content, the water forms "liquid bridges" between the fertilizer particles, generating strong adhesion and causing the particles to stick together. The damp fertilizer is vibrated and squeezed in the fertilizer tank, which will form clumps. The size, weight, and density of the clumps vary greatly, resulting in uneven particle distribution. During spreading, this affects the dynamic balance and the spreading trajectory, leading to uneven fertilizer distribution.

[0004] Therefore, it is necessary to invent a disc-type fertilizer spreading mechanism to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a disc-type fertilizer spreading mechanism that solves the problem of uneven fertilizer spreading when dealing with organic fertilizer with high moisture content and clumps of fertilizer during actual use.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A disc-type fertilizer spreading mechanism includes a fertilizer spreading assembly. The fertilizer spreading assembly includes a fertilizer spreading disc and a transmission column mounted on the drive shaft of a fertilizer spreading vehicle. Multiple guide components are detachably installed on the top of the fertilizer spreading disc. Each guide component includes a guide plate. A crushing component is sleeved on the outside of the transmission column. The crushing component is used to crush large granular fertilizer particles. The crushing component includes a bushing. The bushing is rotatably connected to the transmission column. A locking part is provided at the top of the bushing.

[0007] As a preferred embodiment of this utility model, the crushing component further includes a plurality of crushing mesh surfaces, the same number as the guide plate, wherein the crushing mesh surfaces and the cylindrical surface of the bushing are detachably connected.

[0008] As a preferred embodiment of this utility model, the locking part includes arc-shaped grooves evenly spaced at the top of the bushing, and locking bolts for pressing the bushing. The locking bolts are threadedly connected to the transmission column through the arc-shaped grooves.

[0009] As a preferred embodiment of this utility model, a guide post is provided at the top of the transmission column, and a circular hole is provided at the center of the bushing, which is fitted onto the outside of the guide post.

[0010] As a preferred embodiment of this utility model, the cylindrical surface of the bushing is provided with multiple adjusting grooves at equal intervals, and the fertilizer spreading surface of the guide plate is equipped with an adjustable guide plate. When the bushing rotates along the arc groove, the crushing mesh surface is transferred from the rear end of the fertilizer spreading surface of the guide plate to the front end of the fertilizer spreading surface of the adjacent guide plate.

[0011] In a preferred embodiment of this utility model, one end face of the adjusting chute is in contact with the end face of the crushing mesh; when the end face of the adjusting chute is in contact with the rear side of the guide plate, the end face of the crushing mesh is in contact with the rear side of the guide plate.

[0012] As a preferred embodiment of this utility model, the top of the fertilizer spreading disc is provided with a plurality of adjustment holes for adjusting the position of the guide component, and the bottom of the fertilizer spreading surface of the guide disc is provided with a positioning hole that corresponds to the position of the adjustment hole.

[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows: In this invention, an angle-adjustable crushing component is fitted around the outside of the guide column. When the crushing mesh rotates to the front of the fertilizer spreading disc, the fertilizer spreading disc rotates at high speed. The rotation of the crushing mesh breaks up clumps of fertilizer. The crushed fertilizer, through inertia, is impacted and guided by the spreading disc and spread to the designated area. This overcomes the problem of uneven fertilization caused by clumps and large particles of fertilizer during disc fertilization. When performing conventional fertilization, the fertilizer spreading effect can be ensured by disassembling the crushing component or adjusting the position of the crushing mesh.

[0016] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention.

[0017] This utility model provides, for example Figure 1-4 The illustrated disc-type fertilizer spreading mechanism includes a fertilizer spreading assembly 2, which comprises a fertilizer spreading disc 201 and a transmission column 203 mounted on the drive shaft of a fertilizer spreading vehicle 1. Multiple guide components 3 are detachably mounted on the top of the fertilizer spreading disc 201. Each guide component 3 includes a guide plate 301. A crushing component 4 is sleeved on the outer side of the transmission column 203. The crushing component 4 is used to crush large granular fertilizer particles. The crushing component 4 includes a bushing 401, which is rotatably connected to the transmission column 203. A locking part is provided at the top of the bushing 401. The guide components 3 are used to adjust the spreading distance and direction of the fertilizer. The crushed fertilizer particles are broken by the crushing mesh 402, and the crushed fertilizer is then spread through the guide components 3, thus improving the applicability of the fertilizer spreading device.

[0018] like Figure 3 , 4 As shown, the crushing component 4 also includes a plurality of crushing mesh surfaces 402, the same number as the guide plate 301. The crushing mesh surface 402 and the cylindrical surface of the bushing 401 are detachably connected. The mesh structure of the crushing mesh surface 402 can be sheet-like to avoid the mesh surface from breaking during rotation.

[0019] The locking part includes arc-shaped grooves 403 evenly spaced at the top of the bushing 401, and locking bolts 404 for pressing the bushing 401. The locking bolts 404 are threadedly connected to the transmission column 203 through the arc-shaped grooves 403. When angle adjustment is required, the bushing 401 can be rotated by loosening multiple locking bolts 404. By rotating the bushing 401, the distance between the crushing mesh 402 and the guide plate 301 can be adjusted, thereby switching the crushing function and performing fertilizer spreading operations for fertilizers in different states.

[0020] like Figure 5As shown, a guide post 204 is provided at the top of the transmission post 203, and a circular hole 406 is provided at the center of the bushing 401, which is fitted onto the outside of the guide post 204. The guide post 204 is used to ensure the centering effect of the bushing 401 and to avoid vibration due to instability of the shaft center during rotation.

[0021] The cylindrical surface of the bushing 401 is provided with multiple adjustable grooves 405 at equal intervals. An adjustable guide plate 302 is installed on the fertilizer spreading surface of the guide plate 301. When the bushing 401 rotates along the arc-shaped groove 403, the crushing mesh surface 402 moves from the rear end of the fertilizer spreading surface of the guide plate 301 to the front end of the fertilizer spreading surface of the adjacent guide plate 301. To ensure the crushing effect, the optimal angle between the crushing mesh surface 402 and the front end of the fertilizer spreading surface of the guide plate 301 is 1-10 degrees. The adjustable guide plate 302 is installed on the fertilizer spreading surface of the guide plate 301 and is used to knock up the fertilizer conveyed to the top of the fertilizer spreading plate 201 and spread it to the designated area.

[0022] One end face of the adjusting chute 405 is in contact with the end face of the crushing mesh 402; when the end face of the adjusting chute 405 is in contact with the rear side of the guide plate 301, the end face of the crushing mesh 402 is in contact with the rear side of the guide plate 301. When the crushing mesh 402 is in contact with the guide plate 301, it can avoid the situation where the crushing mesh 402, during the rotation process, might affect the smooth flow of fertilizer into the guide plate 301, which might result in some fertilizer being thrown a shorter distance, thus affecting the throwing effect.

[0023] The top of the fertilizer spreading disc 201 has multiple adjustment holes 202 for adjusting the position of the guide component 3, and the bottom of the fertilizer spreading surface of the guide disc 301 has positioning holes 303 that correspond to the positions of the adjustment holes 202. By installing on different adjustment holes, the tilt angle of the guide disc 301 can be adjusted, thereby adjusting the spreading distance and spreading height. The crushing mesh 402 is detachable and can be adjusted to a suitable aperture and angle as needed.

[0024] This invention utilizes an angle-adjustable crushing component 4 fitted around the outside of the guide post 204. When the crushing mesh 402 rotates to the front of the fertilizer spreading disc 301, the fertilizer spreading disc 201 rotates at high speed. The rotation of the crushing mesh 402 breaks up clumps of fertilizer. The crushed fertilizer, through inertia, is impacted and guided by the guide disc 301 and spread to the designated area, overcoming the problem of uneven fertilization caused by clumps and large particles of fertilizer during disc fertilization. During conventional fertilization, the fertilizer spreading effect can be ensured by disassembling the crushing component 4 or adjusting the position of the crushing mesh 402.

[0025] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
