Description

Technical Field

[0001] This utility model relates to the field of soil loosening technology, specifically a device for rapidly loosening cohesive soil. Background Technology

[0002] Early manual soil loosening methods relied mainly on simple tools such as hoes and shovels, which were extremely labor-intensive and inefficient. Farmers had to spend a lot of time and energy to loosen the soil in a limited area, making it difficult to meet the needs of large-scale farmland operations. Moreover, manual operation could not guarantee the depth and uniformity of loosening, resulting in poor soil improvement. With the development of agricultural mechanization, some simple mechanical loosening equipment emerged. However, most of these devices have rudimentary structures and poor support stability. When working on clay soils, they are prone to shaking and sinking, affecting the continuity and accuracy of operations. For example, some equipment relies only on ordinary wheels for support. In areas with heavy clay soil, the wheels are prone to sinking into the soil, making the equipment unable to move normally. At the same time, their loosening devices are designed in a simple way and cannot effectively break up deep soil compaction. For the unique compact structure of clay soil, it is difficult to achieve comprehensive and deep loosening, resulting in little improvement in soil structure and no fundamental optimization of the crop growth environment.

[0003] Traditional equipment also has shortcomings in power transmission and control. The power system often cannot accurately match the loosening operation requirements. When the power is insufficient, the loosening effect is greatly reduced; when the power is excessive, it leads to energy waste and is prone to excessive damage to the soil structure. Furthermore, existing equipment is difficult to flexibly adjust the loosening force and speed according to the differences in soil cohesion in different regions, and cannot meet the requirements of diverse farmland operation scenarios. In view of the various drawbacks of traditional cohesive soil loosening methods and equipment, it is urgent to develop a rapid cohesive soil loosening equipment that integrates efficient support, precise loosening, and flexible power adjustment to improve agricultural production efficiency, improve soil quality, and promote increased crop yields and income. To this end, we propose a rapid cohesive soil loosening equipment to solve the above-mentioned problems. Utility Model Content

[0007] Preferably, the transmission device includes an engine, which is fixedly connected to the upper surface of the fixed plate.

[0012] This utility model provides an improved device for rapidly loosening cohesive soil, which has the following improvements and advantages compared with the prior art:

[0013] Firstly, this utility model, through the complementary support and loosening device, greatly improves work efficiency and quality. The connecting parts in the support device are firmly connected to the fixed plate, and the round rod and wheels at both ends give the equipment good mobility, making it easy to move flexibly on cohesive soils in different areas. The unique design of the trenching block and baffle not only breaks the surface layer of the soil during movement, preparing for subsequent loosening operations, but also effectively prevents soil splashing and keeps the working environment clean. In the loosening device, the first and second sprockets in the sprocket protective cover drive the third transmission rod and the loosening disc to rotate at high speed through chain transmission. The loosening disc powerfully stirs and breaks up the deep cohesive soil. Combined with the preliminary work of the support device, it can quickly and comprehensively loosen the soil, break up the soil compaction layer, improve the soil structure, and create excellent soil conditions for crop growth.

[0014] Secondly, this utility model achieves efficient power transmission and precise loosening control through the coordinated operation of the transmission and amplification devices. The engine, as the core power source, stably transmits power to the rotating rod via a first pulley, a belt, and a second pulley. The rotating rod connects to the fourth transmission rod in the amplification device, activating the multi-stage gear meshing transmission within the device. For example, the interaction between the first and second gears, and the third and fourth gears, enables multi-stage power transmission and speed adjustment. This design not only provides strong and stable power to the loosening device but also allows for flexible adjustment of the speed and loosening force of the fourth transmission rod according to the viscosity of the soil in different areas. In areas with high soil viscosity, the speed of the fourth transmission rod can be increased through the amplification device to enhance the loosening effect; in areas with low viscosity, the speed can be appropriately reduced to save energy. This achieves precise and efficient loosening of sticky soil, meeting diverse agricultural operation needs. Attached Figure Description

[0022] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. 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 protection scope of the present invention.

[0023] This utility model provides an improved device for rapidly loosening cohesive soil. The technical solution of this utility model is as follows:

[0024] like Figure 1 - Figure 4 As shown, a rapid loosening device for cohesive soil includes a fixed plate 1, a handrail 2 fixedly connected to the upper surface of the fixed plate 1, a support device provided on the lower surface of the fixed plate 1, a transmission device provided on the upper surface of the fixed plate 1, an actuation device provided on the upper surface of the fixed plate 1, and a loosening device provided on the lower surface of the fixed plate 1.

[0025] Furthermore, the support device includes two connectors 3, which are fixedly connected to the lower surface of the fixed plate 1. The inner walls of the two connectors 3 are rotatably connected to the same round rod 4. The two connectors 3 are fixedly connected to the same trenching block 5, which is rotatably connected to the round rod 4. The two side walls of the trenching block 5 are fixedly connected to baffles 6. Both ends of the round rod 4 are fixedly connected to wheels 7. The connectors 3 are firmly connected to the fixed plate 1 to provide stable support for the equipment. The round rod 4 and wheels 7 facilitate flexible movement of the equipment to adapt to different working areas. The trenching block 5 pre-breaks the surface soil layer, and the baffles 6 prevent soil splashing, which protects the equipment and improves the convenience and efficiency of operation.

[0026] Furthermore, the transmission device includes an engine 8, which is fixedly connected to the upper surface of the fixed plate 1. The output end of the engine 8 is fixedly connected to a first pulley 9, and a second pulley 10 is provided on the upper surface of the fixed plate 1. The surfaces of the first pulley 9 and the second pulley 10 are fitted with the same belt 11. A rotating rod 12 is fixedly connected to the left end of the second pulley 10. The engine 8 outputs power stably, which is smoothly transmitted through the first pulley 9 and the second pulley 10. It not only has overload protection function, but also allows for flexible adjustment of the rotation speed of the rotating rod 12 according to the operation requirements, ensuring efficient, safe and precise power transmission.

[0027] Furthermore, the booster device includes a gearbox 13, which is fixedly connected to the upper surface of the fixed plate 1. A fourth transmission rod 26 is rotatably connected to the inner wall of the gearbox 13. A first gear 14 is fixedly connected to the surface of the fourth transmission rod 26. A first transmission rod 15 is rotatably connected to the inner wall of the gearbox 13. A second gear 16 is fixedly connected to the surface of the first transmission rod 15. The first gear 14 and the second gear 16 are meshed together. A third gear 17 is fixedly connected to the surface of the first transmission rod 15. A second transmission rod 18 is rotatably connected to the inner wall of the gearbox 13. A fourth gear 19 is fixedly connected to the surface of the second transmission rod 18. The third gear 17 and the fourth gear 19 are meshed together. The gearbox 13 supports multi-stage gear transmission, which can precisely adjust the power and speed according to the differences in soil viscosity. Under different soil conditions, it can ensure that the loosening disc 28 loosens the soil with appropriate force and speed, thus expanding the applicability of the equipment.

[0028] Furthermore, the loosening device includes a sprocket guard 27, which is fixedly connected to the inner wall of the fixed plate 1. A first sprocket 20 is rotatably connected to the inner wall of the sprocket guard 27, and a second sprocket 24 is rotatably connected to the inner wall of the sprocket guard 27. Multiple chains 25 are meshed between the second sprocket 24 and the first sprocket 20. Two symmetrically arranged connecting rods 21 are fixedly connected to the lower surface of the fixed plate 1. The same fixed block 22 is fixedly connected to the lower surface of the two connecting rods 21. The same third transmission rod 23 is rotatably connected to the inner wall of the two fixed blocks 22. The third transmission rod 23 is rotatably connected to the inner wall of the second sprocket 24. Two symmetrically arranged loosening discs 28 are fixedly connected to the surface of the third transmission rod 23. The sprocket guard 27 protects the internal transmission structure and ensures stable operation. The symmetrically arranged loosening discs 28 rotate at high speed, powerfully breaking up soil compaction, uniformly loosening the soil, effectively improving soil quality, and significantly improving the quality of loosening operations.

[0029] Furthermore, the left end of the rotating rod 12 penetrates the outer wall of the gearbox 13 and extends into the interior. The rotating rod 12 is fixedly connected to the fourth transmission rod 26. The direct connection between the rotating rod 12 and the fourth transmission rod 26 reduces power transmission loss, enables the equipment to respond quickly, enhances the synergy between the transmission device and the booster device, and improves overall work efficiency.

[0030] Furthermore, the left end of the second transmission rod 18 penetrates the inner wall of the gearbox 13 and extends to the outside, and the left end of the second transmission rod 18 penetrates the outer wall of the sprocket protective cover 27 and extends to the inside. The second transmission rod 18 is fixedly connected to the right end of the first sprocket 20. The second transmission rod 18 runs through the power transmission path, and the power transmission from the power source to the loosening component is smooth and unobstructed, ensuring that the equipment operates stably under different working conditions and efficiently completes the soil loosening operation.

[0031] Working principle: When the engine 8 is started, its output end drives the first pulley 9, which is fixedly connected to it, to rotate at high speed. The first pulley 9 transmits power to the second pulley 10 through the belt 11. The second pulley 10 rotates accordingly. Since the left end of the second pulley 10 is fixedly connected to the rotating rod 12, the rotating rod 12 also starts to rotate. The left end of the rotating rod 12 passes through the outer wall of the gearbox 13 and is fixedly connected to the fourth transmission rod 26 in the booster device, thereby driving the fourth transmission rod 26 to rotate. The first gear 14 fixed on the surface of the fourth transmission rod 26 also rotates together. The first gear 14 meshes with the second gear 16 on the surface of the first transmission rod 15, driving the first transmission rod 15 to rotate. A third gear 17 is also fixed on the first transmission rod 15. The third gear 17 meshes with a fourth gear 19 on the surface of the second transmission rod 18, thereby driving the second transmission rod 18 to rotate. This realizes multi-stage gear transmission within the booster device, transmitting and regulating the power transmitted from the engine 8. The left end of the second transmission rod 18 passes through the outer wall of the gearbox 13 and the sprocket protective cover 27, and is fixedly connected to the right end of the first sprocket 20. The rotation of the second transmission rod 18 drives the first sprocket 20 to rotate. The first sprocket 20 and the second sprocket 24 are connected by multiple chains 25, so the second sprocket 24 also begins to rotate. The inner wall of the second sprocket 24 is rotatably connected to the third transmission rod 23. Two symmetrically arranged fourth transmission rods 26 are fixed on the surface of the third transmission rod 23. This causes the loosening discs 28 in the loosening device to start rotating at high speed, stirring and breaking up the sticky soil below, thus achieving soil loosening. In terms of moving the equipment, the operator holds the handle 2 fixed to the upper surface of the fixed plate 1 and pushes the equipment. The two connecting parts 3 in the support device are fixed to the lower surface of the fixed plate 1. The round rod 4 rotatably connected to the inner wall of the connecting part 3 has wheels 7 fixed at both ends, allowing the equipment to move flexibly. During the movement, the trenching block 5 fixed between the connecting parts 3 is rotatably connected to the round rod 4. The trenching block 5 can open shallow trenches in the soil surface. The baffles 6 fixed on its two side walls can prevent soil from splashing, and at the same time create more favorable conditions for subsequent loosening operations, so as to better complete the rapid loosening of sticky soil in conjunction with the loosening device.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this invention.
