However, the aforementioned patent has the following shortcomings: during use, the soil conditioner inside the storage column falls from the conduit only by gravity, failing to achieve uniform application of the soil conditioner and affecting the overall consistency of the soil improvement effect. Therefore, this utility model proposes a new solution. Utility Model Content

[0004] The purpose of this invention is to solve the problem that when the soil conditioner inside the storage column of the above-mentioned patent is used, it relies solely on gravity to fall from the inside of the conduit, which makes it impossible to achieve uniform spraying of the soil conditioner and affects the overall soil improvement effect. Therefore, this invention proposes a soil improvement device for seedling planting.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A soil improvement device for seedling planting includes a first crossbeam and a second crossbeam, which are fixedly connected by a longitudinal beam. A connecting rod is fixedly installed on the side wall of the first crossbeam away from the second crossbeam. Soil loosening mechanisms are installed on both the first crossbeam and the longitudinal beam. The device also includes: The storage box is detachably mounted on the second crossbeam via multiple connecting mechanisms. A trapezoidal discharge hopper is installed at the bottom of the storage box, and openings are provided at both the top and bottom of the discharge hopper. A feeding roller is disposed inside the discharge hopper and rotatably connected to the storage box. Both ends of the feeding roller extend out of the storage box and are fixedly installed with rollers located outside the storage box. The first crushing roller and the second crushing roller are symmetrically arranged above the feeding roller and are rotatably connected to the storage box. The first crushing roller and the second crushing roller are connected by a first transmission mechanism, and the first crushing roller and the feeding roller are connected by a second transmission mechanism.

[0006] As a preferred technical solution of this utility model, the connecting mechanism includes a mounting plate fixedly connected to the outer wall of the storage box, a plug rod fixedly connected to the bottom of the mounting plate, a through hole for the second crossbeam that cooperates with the plug rod, and a limiting bolt threadedly connected to the plug rod.

[0007] As a preferred technical solution of this utility model, a first protective cover is provided on the outer side of the first transmission mechanism and installed on the outer wall of the storage box, and a second protective cover is provided on the outer side of the second transmission mechanism and installed on the outer wall of the storage box.

[0008] As a preferred technical solution of this utility model, the first transmission mechanism includes a first gear fixedly installed at one end of the first crushing roller, and a second gear that meshes with the first gear is fixedly installed at one end of the second crushing roller.

[0009] As a preferred technical solution of this utility model, the second transmission mechanism includes a first sprocket fixedly installed at the other end of the first crushing roller, and a second sprocket fixed at one end of the feeding roller. The first sprocket and the second sprocket are connected by chain drive.

[0010] As a preferred technical solution of this utility model, the feeding roller includes a mounting shaft, and a plurality of evenly distributed feeding plates are fixedly mounted on the outer wall of the feeding roller.

[0011] As a preferred technical solution of this utility model, limit guide rods are fixedly installed at the four corners of the bottom of the discharge hopper, and a shaking plate that is inclinedly arranged below the bottom opening of the discharge hopper is slidably installed on the four limit guide rods. A spring located at the bottom of the shaking plate is sleeved on the outer side of the limit guide rod, and a cam that cooperates with the shaking plate is fixedly installed on the outer wall of the mounting shaft.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. In this soil amendment device for seedling planting, the rollers in contact with the ground drive the feeding roller to rotate inside the discharge hopper, thereby quantitatively dispensing the soil amendment from the storage box from the discharge hopper through the feeding roller. This solves the problem in the existing technology that the soil amendment cannot be evenly distributed by relying solely on gravity to spread it, thus ensuring the consistency of the soil amendment effect.

[0013] 2. The soil amendment device for seedling planting, when in use, the rotating first and second crushing rollers can disperse the clumps of soil amendment inside the storage box into uniform particles, preventing the clumps of soil amendment from clogging between the feeding roller and the discharge hopper, avoiding the problem of material interruption during the sowing process, and ensuring the continuity of operation.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0019] like Figures 1-5As shown, this embodiment proposes a soil improvement device for seedling planting, including a first crossbeam 1 and a second crossbeam 2, which are fixedly connected by a longitudinal beam 3. A connecting rod 4 is fixedly installed on the side wall of the first crossbeam 1 away from the second crossbeam 2. Soil loosening mechanisms 5 are installed on both the first crossbeam 1 and the longitudinal beam 3. The device also includes: a storage box 7, which is detachably installed on the second crossbeam 2 via multiple connecting mechanisms 6. A trapezoidal discharge hopper 12 is installed at the bottom of the storage box 7, with openings at both the top and bottom of the discharge hopper 12; and a feeding roller 11, which is installed at the discharge point. The inner side of the bucket 12 is rotatably connected to the storage box 7. Both ends of the feeding roller 11 extend out of the storage box 7, and both ends of the feeding roller 11 are fixedly installed with rollers 10 located outside the storage box 7. The first crushing roller 8 and the second crushing roller 9 are symmetrically arranged above the feeding roller 11 and rotatably connected to the storage box 7. The first crushing roller 8 and the second crushing roller 9 are connected by a first transmission mechanism, and the first crushing roller 8 and the feeding roller 11 are connected by a second transmission mechanism. Both the first crushing roller 8 and the second crushing roller 9 include roller shafts, and the outer walls of the roller shafts are fixedly connected to... With multiple evenly distributed crushing teeth, the roller 10 in contact with the ground during use drives the feeding roller 11 to rotate inside the discharge hopper 12. This feeding roller 11 quantitatively dispenses the soil conditioner from the storage tank 7 through the discharge hopper 12, solving the problem in existing technologies where soil conditioner is spread only by gravity and cannot be evenly distributed, ensuring consistent soil improvement results. During use, the rotating first crushing roller 8 and second crushing roller 9 disperse any clumps of soil conditioner inside the storage tank 7 into uniform particles through the crushing teeth, preventing further clumping. The soil conditioner is blocked between the feeding roller 11 and the discharge hopper 12 to avoid material interruption during the spreading process and ensure the continuity of the operation. When in use, the roller 10 can drive the feeding roller 11 to rotate. The rotating feeding roller 11 can drive the first crushing roller 8 to rotate through the second transmission mechanism. The rotating first crushing roller 8 can drive the second crushing roller 9 to rotate through the first transmission mechanism. In the process of quantitative feeding and crushing, no additional motor is needed. The crushing, feeding and spreading process can be completed by relying only on the traveling power of the traction mechanism connected to the connecting rod 4.

[0020] in, like Figures 1-4As shown, the connecting mechanism 6 includes a mounting plate 61 fixedly connected to the outer wall of the storage box 7. A plug rod 62 is fixedly connected to the bottom of the mounting plate 61. A plug hole 20 that mates with the plug rod 62 is opened through the second crossbeam 2. A limiting bolt 63 that is threadedly connected to the plug rod 62 is installed through the plug rod 62. It should be noted that in use, the plug rod 62 is inserted into the plug hole 20, and then the limiting bolt 63 is screwed onto the plug rod 62 to limit its movement, thus completing the connection between the storage box 7 and the second crossbeam 2. When the storage box 7 needs to be disassembled, the limiting bolt 63 is unscrewed and the plug rod 62 is pulled out from the plug hole 20. This facilitates the installation and disassembly of the storage box 7, allowing the device to be disassembled and separated during transportation, reducing the space occupied.

[0021] like Figure 1 and Figure 3 As shown, the first transmission mechanism includes a first gear 14 fixedly installed at one end of the first crushing roller 8, and a second gear 15 fixedly installed at one end of the second crushing roller 9, meshing with the first gear 14. It should be noted that during use, the rotating first crushing roller 8 can drive the meshing second gear 15 to rotate via the first gear 14, thereby driving the second crushing roller 9 to rotate. During the simultaneous rotation of the first crushing roller 8 and the second crushing roller 9, the soil conditioner inside the storage tank 7 is crushed, thus preventing clumps of soil conditioner from getting stuck between the first crossbeam 1 and the discharge hopper 12.

[0022] like Figure 1 and Figure 4 As shown, the second transmission mechanism includes a first sprocket 16 fixedly mounted on the other end of the first crushing roller 8, and a second sprocket 17 fixed to one end of the feeding roller 11. The first sprocket 16 and the second sprocket 17 are connected by a chain 18. It should be noted that during use, the rotating feeding roller 11 drives the first sprocket 16 to rotate through the second sprocket 17 and the chain 18, thereby driving the first crushing roller 8 to rotate, without the need for an additional motor for the first crushing roller 8.

[0023] To further explain, such as Figures 1-4 As shown, a first protective cover 13 is installed on the outer wall of the storage box 7 on the outer side of the first transmission mechanism, and a second protective cover 19 is installed on the outer wall of the storage box 7 on the outer side of the second transmission mechanism. It should be noted that the first protective cover 13 and the second protective cover 19 can protect the first and second transmission mechanisms and prevent soil, stones, and other debris from entering the interior of the first and second transmission mechanisms during use.

[0024] In this embodiment, as Figure 5As shown, the feeding roller 11 includes a mounting shaft 111, and multiple evenly distributed dispensing plates 112 are fixedly mounted on the outer wall of the feeding roller 11. It should be noted that during use, the rollers 10 connected to both ends of the mounting shaft 111 will drive the mounting shaft 111 to rotate, thereby driving the multiple dispensing plates 112 to rotate. The dispensing plates 112 will then dispense the soil conditioner from the inside of the discharge hopper 12, allowing it to be evenly spread into the soil.

[0025] like Figure 5 As shown, limit guide rods 22 are fixedly installed at the four corners of the bottom of the discharge hopper 12. A dispersing plate 21, inclined and positioned below the bottom opening of the discharge hopper 12, is slidably mounted on the four limit guide rods 22. A spring 23 is sleeved on the outer side of the limit guide rods 22, located at the bottom of the dispersing plate 21. A cam 24, cooperating with the dispersing plate 21, is fixedly installed on the outer wall of the mounting shaft 111. It should be noted that as the mounting shaft 111 rotates with the roller 10, it drives the cam 24 to rotate, thereby causing the dispersing plate 21 to slide up and down along the limit guide rods 22. This disperses the soil conditioner particles falling onto the dispersing plate 21, making them fall more evenly into the soil, further improving the soil improvement effect. The spring 23 allows the dispersing plate 21 to return to its original position.

[0026] Specifically, the working principle of this soil amendment device for seedling planting is as follows: Before use, the device is connected to a tractor or other traction mechanism via the connecting rod 4. Then, the granular soil amendment is poured into the storage box 7. When the tractor drives the device forward, the roller 10 in contact with the ground will drive the feeding roller 11 to rotate, thereby spreading the soil amendment evenly through the discharge hopper 12. At the same time, the rotating feeding roller 11 will drive the first sprocket 16 to rotate through the second sprocket 17 and the chain 18, thereby driving the first crushing roller 8 to rotate. The rotating first crushing roller 8 can drive the second gear 15 meshing with it to rotate through the first gear 14, thereby driving the second crushing roller 9 to rotate. During the simultaneous rotation of the first crushing roller 8 and the second crushing roller 9, the clumps of soil amendment inside the storage box 7 will be broken up, thereby preventing the clumps of soil amendment from getting stuck between the first crossbeam 1 and the discharge hopper 12.

[0027] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the invention, are covered within the scope of the claims of the present utility model.
