Description

Technical Field

[0001] This invention relates to the field of soil structure improvement technology, and in particular to a soil loosening device for soil structure improvement. Background Technology

[0002] Soil structure improvement is crucial for the sustainable development of agriculture, the ecological environment, and human society. A well-structured soil can retain nutrients and reduce nutrient loss. Soil aggregates have good permeability and water and fertilizer retention capacity; they can adsorb nutrients on the surface or inside the aggregates, preventing nutrient loss with water. Improving soil structure increases soil porosity and aeration. Plant roots and soil microorganisms require sufficient oxygen for respiration. If soil aeration is poor, root and microbial respiration will be inhibited, affecting plant growth and the balance of the soil ecosystem.

[0003] In existing technologies, when the soil moisture content is too high or the clay mineral content is high, which increases the soil adhesion, the sticky soil will tightly wrap around the loosening shovel and the transmission parts of the equipment. This will cause the equipment to have difficulty entering the soil and increase the traction resistance, which will slow down the equipment's movement speed, reduce the area of ​​loosening soil per unit time, and fail to fully break up the soil aggregate structure, which is not conducive to improving the soil's aeration and permeability. Therefore, a soil loosening device for soil structure improvement is proposed. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies, where when soil moisture content is too high or clay mineral content is high, resulting in increased soil adhesion, the sticky soil will tightly wrap around the loosening shovel and the transmission components of the equipment. This leads to difficulties in soil entry, increased traction resistance, slower equipment movement, reduced loosening area per unit time, and inability to fully break up soil aggregates, which is detrimental to improving soil aeration and permeability. Therefore, this invention proposes a soil loosening device for soil structure improvement.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A soil loosening device for soil structure improvement includes a vehicle body and a base plate. A linkage loosening mechanism is provided below the base plate. The linkage loosening mechanism includes a first motor located below the base plate, a drive rod located at the output end of the first motor, a worm gear fixedly connected to the side of the drive rod near the first motor, a worm wheel meshing with the side of the worm gear, a transmission rod fixedly connected below the worm wheel, a first bevel gear fixedly connected to the side of the transmission rod, a second bevel gear meshing with the side of the first bevel gear, a pressure plate fixedly connected to the side of the second bevel gear, a circular frame seat located below the pressure plate, a connecting shaft slidably connected below the circular frame seat, a fixed connection between the transmission rod and the connecting shaft, a hollow cylinder fixedly connected below the side of the circular frame seat away from the lower pressure cylinder, a sliding plate fixedly connected to the connecting shaft near the interior of the hollow cylinder, a spring for generating vibration located below the side of the circular frame seat near the connecting shaft, and a loosening shovel for loosening soil located at the bottom of the hollow cylinder.

[0006] The worm and worm wheel are arranged in multiple sets in a linear arrangement outside the drive rod, and other components below each set of worm and worm wheel are also arranged in multiple sets, which can form regional operation.

[0007] The above technical solution further includes: The base plate is fixedly connected to the first motor. A limiting groove is provided inside the hollow shaft cylinder on the side near the slide plate. The limiting groove allows the slide plate to slide only up and down and not left and right.

[0008] The spring is disposed in a groove opened inside the connecting shaft and is fixedly connected to the connecting shaft. Multiple sets of the spring are arranged in a circular pattern between the annular frame seat and the connecting shaft.

[0009] The second bevel gear is fixedly connected to a first support rod on the side near the pressure plate, and the first support rod is rotatably connected to the base plate.

[0010] A second support rod is fixedly connected above the worm gear, and the second support rod is rotatably connected to the base plate.

[0011] A groove plate is fixedly connected to the top of the vehicle body.

[0012] A second motor is provided on the top of the slot plate, and a threaded rod is provided at the output end of the second motor. A movable plate is threadedly connected to the side of the threaded rod near the base plate.

[0013] The movable plate is fixedly connected to the base plate, the movable plate is disposed in the groove opened in the slot plate, and the movable plate is slidably connected to the slot plate.

[0014] A storage box is provided above the side of the vehicle body closest to the trough plate.

[0015] The storage bin is provided with a feed inlet at the top and a discharge pipe at the bottom.

[0016] The present invention has the following beneficial effects: 1. In this invention, the first motor drives the drive rod to rotate, which in turn drives the transmission rod to rotate. The transmission rod, through the transmission of the first and second bevel gears, drives the pressure plate to rotate in a circular motion. The pressure plate periodically presses the lower pressure cylinder, which in turn drives the circular frame seat to press down. The transmission rod drives the connecting shaft to rotate. The connecting shaft engages with the limiting groove inside the hollow shaft cylinder through a sliding plate, causing the hollow shaft cylinder to vibrate vertically while rotating. This, in turn, drives the loosening shovel to rotate and vibrate vertically, breaking down the cohesion between soil particles, making the soil particles loose, reducing soil adhesion, thereby reducing the difficulty of the equipment entering the soil and the traction resistance. This allows the equipment to operate more smoothly in the soil, increasing the travel speed, increasing the loosened area per unit time, and significantly improving work efficiency.

[0017] 2. In this invention, when the second motor is started, the threaded rod rotates on the inner wall of the trough plate, generating spiral power to drive the moving plate to slide on the inner wall of the trough plate, thereby driving the base plate and the linkage loosening mechanism to move up and down. In actual operation, the operator can adjust the working depth of the linkage loosening mechanism at any time according to different soil conditions and operation requirements, so that this invention can adapt to a variety of different soil environments and operation scenarios, and meet diverse needs.

[0018] 3. In this invention, a storage box is installed on the vehicle body, providing a more comprehensive solution for soil structure improvement. The storage box can store a variety of materials for soil improvement. Through the feed port set on the top of the storage box, these improvement materials can be easily added to the storage box. During the operation of the equipment, the feed pipe set at the bottom of the storage box can evenly spread the improvement materials into the soil. Combined with the loosening operation of the linked loosening mechanism, the improvement materials can be better mixed with the soil, giving full play to their improvement effect, thereby improving the soil structure faster and more effectively.

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

[0022] Please see Figures 1-7 As shown, this invention is a soil loosening device for soil structure improvement, including a vehicle body 1 and a base plate 2. A linkage loosening mechanism is provided below the base plate 2. The linkage loosening mechanism includes a first motor 3 located below the base plate 2. A drive rod 4 is provided at the output end of the first motor 3. A worm gear 5 is fixedly connected to the side of the drive rod 4 near the first motor 3. A worm wheel 6 is meshed with the side of the worm gear 5. A transmission rod 7 is fixedly connected below the worm wheel 6. A first bevel gear 8 is fixedly connected to the side of the transmission rod 7. A second bevel gear 9 is meshed with the side of the first bevel gear 8. A pressure plate 10 is fixedly connected to the side, and a circular frame seat 12 is provided below the pressure plate 10. A connecting shaft 13 is slidably connected below the circular frame seat 12. The transmission rod 7 is fixedly connected to the connecting shaft 13. A hollow shaft cylinder 14 is fixedly connected to the lower side of the circular frame seat 12 away from the lower pressure cylinder 11. A sliding plate 16 is fixedly connected to the connecting shaft 13 near the inside of the hollow shaft cylinder 14. A spring 17 for generating vibration is provided on the lower side of the circular frame seat 12 near the connecting shaft 13. A soil loosening shovel 18 for loosening soil is provided at the bottom of the hollow shaft cylinder 14.

[0023] The base plate 2 is fixedly connected to the first motor 3. A limiting groove 15 is provided inside the hollow shaft cylinder 14 on the side near the slide plate 16. The limiting groove 15 makes the slide plate 16 only able to slide up and down and not left and right.

[0024] The spring 17 is set in a groove inside the connecting shaft 13 and is fixedly connected to the connecting shaft 13. Multiple sets of springs 17 are arranged in a circular pattern between the annular frame seat 12 and the connecting shaft 13.

[0025] In this embodiment, the linkage loosening mechanism located below the base plate 2 is activated. The first motor 3, which is fixedly installed below the base plate 2 in the linkage loosening mechanism, starts to run. When the first motor 3 runs, it controls the drive rod 4 located at its output end to rotate. When the drive rod 4 rotates, it drives the worm gear 5 fixedly connected to its side to rotate. When the worm gear 5 rotates, it drives the worm wheel 6 meshing with its side to rotate. This causes the worm wheel 6 to drive the transmission rod 7 fixedly installed below it to rotate. At the same time, the rotation of the transmission rod 7 drives the first bevel gear 8 fixedly connected to its side to rotate. When the first bevel gear 8 rotates, it drives the second bevel gear 9 to rotate synchronously through its meshing connection with the second bevel gear 9. When the second bevel gear 9 rotates, it drives the pressure plate 10, which is fixedly connected to its side, to rotate in a circular motion. This causes the pressure plate 10 to press down on the lower pressure cylinder 11 once per revolution. A circular frame seat 12 is fixedly connected to the lower pressure cylinder 11. The lower pressure cylinder 11 drives the circular frame seat 12 to press down. A spring 17 is provided between the circular frame seat 12 and the connecting shaft 13. When the circular frame seat 12 presses down, it causes the spring 17 to gradually compress into the groove of the connecting shaft 13, thereby generating an elastic potential. Yes, and multiple sets of springs 17 are provided to ensure sufficient accumulation of elastic potential energy. When the annular frame seat 12 is not compressed, the springs 17 will use their elastic potential energy to drive the annular frame seat 12 to rotate up and down. At the same time, when the transmission rod 7 rotates, it will drive the connecting shaft 13 to rotate synchronously. The other end of the connecting shaft 13 is located inside the hollow shaft cylinder 14, and the hollow shaft cylinder 14 is fixedly connected to the annular frame seat 12. A sliding plate 16 is fixedly connected to the side of the hollow shaft cylinder 14, and the sliding plate 16 is slidably connected to the inner wall of the limiting groove 15 opened inside the hollow shaft cylinder 14, so that the connecting shaft 13 can drive the hollow shaft cylinder 12 to rotate up and down. 4. When the circular frame seat 12 rotates synchronously and the circular frame seat 12 drives the hollow shaft cylinder 14 to vibrate vertically up and down, the slide plate 16 can only slide up and down on the inner wall of the limiting groove 15 and cannot slide left and right. This allows the hollow shaft cylinder 14 to rotate and form vertical vibration up and down. The hollow shaft cylinder 14 will drive the loosening shovel 18 set below to rotate and maintain vertical vibration up and down. This can effectively break the cohesion between soil particles and make the originally tightly bound soil particles loose. When the cohesion between soil particles is destroyed, the adhesion of the soil will decrease, thereby reducing the difficulty of the equipment entering the soil.

[0026] In one embodiment, the first support rod 19 is fixedly connected to the side of the pressure plate 10, and the first support rod 19 is rotatably connected to the substrate 2.

[0027] In this embodiment, when the second bevel gear 9 rotates, the second bevel gear 9 will drive the first support rod 19, which is fixedly connected to its side, to rotate. The other end of the first support rod 19 will rotate on the inner wall of the substrate 2. The first support rod 19 can ensure the stability of the second bevel gear 9 when it rotates and fix the second bevel gear 9 in that position so that its position will not change with the rotation of the first bevel gear 8.

[0028] In one embodiment, for the worm gear 6, a second support rod 20 is fixedly connected above the worm gear 6, and the second support rod 20 is rotatably connected to the base plate 2.

[0029] In this embodiment, when the worm gear 6 rotates, it will drive the second support rod 20, which is fixedly connected to it above, to rotate. The other end of the second support rod 20 will rotate under the inner wall of the substrate 2 to ensure the structural stability at that location.

[0030] In one embodiment, for the vehicle body 1, a groove plate 21 is fixedly connected to the top of the vehicle body 1.

[0031] A second motor 22 is provided on the top of the slot plate 21. A threaded rod 23 is provided at the output end of the second motor 22. A movable plate 24 is threadedly connected to the side of the threaded rod 23 near the base plate 2.

[0032] The movable plate 24 is fixedly connected to the base plate 2, and the movable plate 24 is disposed in the groove opened in the groove plate 21. The movable plate 24 and the groove plate 21 are slidably connected.

[0033] In this embodiment, a groove plate 21 is provided above the vehicle body 1. The groove plate 21 has a groove inside. When the second motor 22 is activated, it can control the threaded rod 23 to rotate on the inner wall of the groove plate 21. The threaded rod 23 will rotate through the inside of the moving plate 24 and generate spiral power. When the threaded rod 23 rotates, it can drive the moving plate 24 to slide on the inner wall of the groove inside the groove plate 21. Thus, the moving plate 24 can drive the base plate 2 and the linkage loosening mechanism to move up and down, and the soil structure improvement depth can be adjusted at any time.

[0034] In one embodiment, for the vehicle body 1, a storage box 25 is provided above the side of the vehicle body 1 near the trough plate 21.

[0035] The storage bin 25 is provided with a feed inlet 26 at the top and a discharge pipe 27 at the bottom.

[0036] In this embodiment, a storage box 25 is provided above the vehicle body 1. The storage box 25 can store sand, which can improve the soil texture and reduce soil stickiness. It can also store humic acid, peat, etc., which contain rich organic matter and a variety of active groups. They can combine with soil particles to form a stable aggregate structure, improve soil aeration and permeability, and reduce soil stickiness. The material is put in through the feed port 26 provided at the top of the storage box 25, and the discharge pipe 27 provided at the bottom of the storage box 25 can discharge the soil improvement material stored in the storage box 25 to help improve the soil structure quickly.

[0037] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
