Description

Technical Field

[0001] This utility model belongs to the field of agricultural machinery technology, and in particular to a soil clod separation and crushing device for a trenching seeder. Background Technology

[0002] In agricultural planting, furrow-opening seeders are commonly used equipment, capable of completing furrowing and sowing operations in one go, greatly improving planting efficiency. However, in actual use, it has been found that existing furrow-opening seeders turn up soil during furrowing, forming clods of varying sizes. If these clods are not effectively treated, they will adversely affect subsequent sowing, seed germination, and seedling growth. When the cleaning effect is weak, clods, weeds, and other debris will adhere to and become entangled in large quantities on the surface of the pulverizer and between the roller teeth. These deposits increase the resistance to the rotation of the pulverizing wheel, causing the pulverizing wheel speed to decrease and reducing pulverizing efficiency.

[0003] A search revealed Chinese patent documents (authorization announcement number CN214708601U), which discloses a furrow seeder, relating to the field of seeder technology. This invention utilizes a crushing mechanism to crush larger clods of soil, preventing damage and improving the device's applicability and lifespan. A lifting mechanism allows adjustment of the crushing mechanism's height, enabling the device to adapt to different working positions and further enhancing its practicality. While the device meets basic usage requirements, when the clearing effect is weak, clods of soil, weeds, and other debris tend to adhere to and become entangled on the crusher surface and between the roller teeth. These deposits increase the resistance to the crushing wheel's rotation, reducing its speed and crushing efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a soil clod separation and crushing device for a trenching seeder, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a soil clod separation and crushing device for a furrowing seeder, comprising a moving frame, a fixed frame welded inside the moving frame, and a fixed plate welded to the end of the fixed frame;

[0006] The fixed plate has guide grooves on both sides for movement. Springs are connected inside each guide groove. A movable disk is connected to one end of each spring. The movable disk is slidably disposed inside the guide groove. A rotating rod is rotatably connected inside the movable disk. A cleaning wheel for cleaning is installed on the outer periphery of the rotating rod. A motor is slidably installed on one side of the fixed plate. The output shaft of the motor is connected to the end of the rotating rod through a coupling.

[0007] Preferably, the bottom of the fixed plate is welded with two connecting plates, and a rotating column is rotatably connected inside the two connecting plates. A crushing wheel for separating and crushing soil clods is installed on the outer periphery of the rotating column, and multiple separation plates are installed on the bottom of the fixed plate.

[0008] Preferably, the bottom of the walking frame is equipped with four walking wheels for movement, the four walking wheels are connected by a rotating shaft, a connecting part is installed on the outer periphery of the rotating shaft, and a connecting shaft is connected to the movable part of the connecting part.

[0009] Preferably, a seed box for holding seeds is installed on the top of the walking frame, and the connecting shaft is rotatably installed inside the seed box.

[0010] Preferably, two seeding wheels are installed on the outer periphery of the connecting shaft, and multiple seed inlet grooves for seed entry are provided on the outer periphery of the two seeding wheels.

[0013] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0014] This clod separating and crushing device for a furrowing seeder benefits from the structure of the crushing wheel. When the walking frame moves, the rake installed at the front of the walking frame turns over the soil, and the crushing wheel comes into contact with the turned soil, crushing the soil. Compared with the traditional clod separating and crushing device for furrowing seeders, which has a weaker cleaning effect, this structure can improve the cleaning ability, prevent soil clods, weeds and other debris from adhering and tangling in large quantities on the surface of the crusher and between the roller teeth, reduce the resistance of the crushing wheel rotation, increase the speed of the crushing wheel, and improve the crushing efficiency.

[0015] This trenching seeder's soil clod separation and crushing device benefits from the structure of the cleaning wheel. The motor drives the rotating rod and the cleaning wheel to rotate, and the cleaning wheel cleans the soil on the surface of the crushing wheel to prevent excessive soil accumulation from affecting the crushing efficiency. The spring presses the moving disc downward to increase the contact pressure between the cleaning wheel and the crushing wheel, thereby improving the cleaning effect of the cleaning wheel on the crushing wheel.

[0025] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0026] like Figures 1 to 5 The soil clod separation and crushing device of the trenching seeder shown includes a walking frame 1 for movement, a fixed frame 106 welded inside the walking frame 1, and a fixed plate 3 welded to the end of the fixed frame 106.

[0027] The fixed plate 3 has guide grooves 301 for movement on both sides. Springs 302 are connected inside the two guide grooves 301. One end of the spring 302 is connected to a moving disk 303. The moving disk 303 is slidably disposed inside the guide groove 301. A rotating rod 304 is rotatably connected inside the moving disk 303. A cleaning wheel 305 for cleaning is installed on the outer periphery of the rotating rod 304. A motor 306 is slidably installed on one side of the fixed plate 3. The output shaft of the motor 306 is connected to the end of the rotating rod 304 through a coupling. When the walking frame 1 moves, the plow installed at the front of the walking frame 1 turns over the soil. The crushing wheel 402 contacts the turned soil and crushes the soil.

[0028] Two connecting plates 4 are welded to the bottom of the fixed plate 3. A rotating column 401 is rotatably connected inside the two connecting plates 4. A crushing wheel 402 for separating and crushing soil clods is installed on the outer periphery of the rotating column 401. Multiple separation plates 403 are installed at the bottom of the fixed plate 3. When the motor 306 is turned on, the motor 306 drives the rotating rod 304 and the cleaning wheel 305 to rotate. The cleaning wheel 305 cleans the soil on the surface of the crushing wheel 402 to prevent excessive soil accumulation, which would affect the crushing efficiency. The spring 302 presses the moving disc 303 downward to increase the contact pressure between the cleaning wheel 305 and the crushing wheel 402, thereby improving the cleaning effect of the cleaning wheel 305 on the crushing wheel 402.

[0029] The bottom of the walking frame 1 is equipped with four walking wheels 101 for movement. A rotating shaft 103 is connected between the four walking wheels 101. A connecting part 104 is installed on the outer periphery of the rotating shaft 103. A connecting shaft 105 is connected to the movable part of the connecting part 104. A seeding box 2 for holding seeds is installed on the top of the walking frame 1. The connecting shaft 105 is rotatably installed inside the seeding box 2.

[0030] Two seeding wheels 201 are mounted on the outer periphery of the connecting shaft 105. Multiple seed inlet slots 202 for seed entry are provided on the outer periphery of the two seeding wheels 201. A seed outlet 203 is located at the bottom of the seed box 2, and a seeding tube 204 for sowing is connected to the bottom of the seed outlet 203. A soil covering plate 102 and a furrowing plow 205 are mounted on the bottom of the traveling frame 1. The furrowing plow 205 mainly consists of a plowshare, plowshare, and plow column. Its working principle is that it is connected to a power machine, and during travel, it utilizes the plowshare... The plow cuts into the soil, breaks it up, and flips it to one side to create a trench that meets the requirements. The walking frame 1 is connected to an external power mechanism, and the walking frame 1 is pulled to move. Seeds are placed in the seeding box 2. When the walking wheel 101 moves, the rotating shaft 103 drives the connecting part 104 to rotate. The connecting part 104 drives the connecting shaft 105 to rotate. The connecting shaft 105 drives the seeding wheel 201 to rotate. The seed inlet trough 202 puts the seeds in the seeding box 2 into the seed outlet 203 and discharges them from the seeding tube 204.

[0031] Working principle

[0032] In use, the soil clod separating and crushing device of this furrowing seeder is first connected to the external power mechanism. The walking frame 1 is then moved, and seeds are placed in the seed box 2. As the walking wheels 101 move, the rotating shaft 103 drives the connecting part 104 to rotate, which in turn drives the connecting shaft 105 to rotate. The connecting shaft 105 then drives the seeding wheel 201 to rotate. The seed inlet trough 202 feeds the seeds from the seed box 2 into the seed outlet 203, from which the seeds are discharged through the seeding tube 204. As the walking frame 1 moves, the walking... The plow installed at the front of frame 1 turns over the soil. The crushing wheel 402 comes into contact with the turned soil and crushes it. The motor 306 is turned on, which drives the rotating rod 304 and the cleaning wheel 305 to rotate. The cleaning wheel 305 cleans the soil on the surface of the crushing wheel 402 to prevent excessive soil accumulation, which would affect the crushing efficiency. The spring 302 presses the moving disc 303 downward to increase the contact pressure between the cleaning wheel 305 and the crushing wheel 402, thereby improving the cleaning effect of the cleaning wheel 305 on the crushing wheel 402.
