Description

Technical Field

[0001] The utility model relates to the technical field of agricultural planting, and more particularly to a soil loosening device for agricultural planting soil. Background Art

[0002] Among existing technologies, traditional manual soil loosening operations not only require a lot of time and manpower, but are also labor-intensive and difficult to adapt to the high efficiency demands of modern agriculture. As the scale of agriculture continues to expand, higher requirements are placed on land utilization efficiency, while the speed and effectiveness of manual soil loosening are far from meeting the needs of large-scale agricultural production. In addition, the lack of professional soil loosening tools often leads to the destruction of soil structure, which may affect the air permeability and water retention of the soil, and thus affect the growth and development of crops. The increased compaction of the soil not only restricts the penetration and expansion of the root system, but may also prevent water and nutrients from effectively penetrating deep into the soil, affecting the ability of crops to absorb water and nutrients.

[0003] At the same time, the adaptability of existing loosening devices is also a significant problem. Since different types of loosening knives cannot be quickly adjusted or replaced, these devices are powerless when faced with different soil conditions. Operators may need to use tools to install and replace the loosening knives, which not only increases the complexity of the operation, but also increases the labor intensity. This limitation is particularly obvious in situations where the loosening depth and width need to be adjusted frequently. Therefore, in order to improve the efficiency and adaptability of agricultural production, there is an urgent need for a loosening device that can quickly and conveniently adjust and replace the loosening knives to adapt to different soil types and planting needs.

The quick-loading mechanism includes a clamping rod 9, a clamping groove 10, a clamping sleeve 11, a clamping block 12, a locking sleeve 13, a rotating wheel 14 and a spring 15. The clamping rod 9 is arranged on the mounting plate 7, the clamping groove 10 is arranged on the outer wall of the clamping rod 9, the clamping sleeve 11 is arranged on the outer wall of the clamping rod 9, the clamping block 12 is provided with multiple groups of rotatable installations on the clamping sleeve 11, the locking sleeve 13 slides on the outer wall of the clamping sleeve 11, the rotating wheel 14 is provided with multiple groups of installations on the locking sleeve 13, and the spring 15 is fixedly arranged on the top of the locking sleeve 13.

[0031] The output end of the motor 2 is connected to a reducer 16, and a transmission rod 17 is installed at the output end of the reducer 16. The two sets of transmission rods 17 are rotatably connected to the two sets of connecting rods 6. The gear transmission system 3 is connected to the transmission rod 17. The function of the reducer 16 is to reduce the output speed of the motor and increase the torque, so that the transmission is smoother and more powerful. The transmission rod 17 transmits the power of the reducer to the connecting rod 6, driving it to rotate. This design enables the loosening knife 8 to obtain sufficient power to loosen the soil, while ensuring the uniformity and efficiency of the operation.

[0032] Moving wheels 18 are installed on both sides of the gear transmission system 3. The design of the moving wheels 18 allows the entire loosening device to be flexibly moved in the field, making it convenient to adjust the working position. It reduces the friction resistance of the device during movement, reduces energy consumption, and also protects the gear transmission system 3 from the impact of uneven ground.

[0033] A limit rod 19 is provided on the clamping sleeve 11. There are multiple groups of limit rods 19 and they are slidably connected to the locking sleeve 13. The sliding connection between the limit rod 19 and the locking sleeve 13 limits the position of the loosening knife 8 to prevent it from penetrating too deep into the soil, thereby protecting the mechanism and soil structure.

[0034] A positioning block 20 is provided at the top of the clamping rod 9, and a positioning groove 21 is provided at the top of the clamping sleeve 11. The coordinated use of the positioning block 20 and the positioning groove 21 ensures the correct position of the loosening knife 8 during installation and improves the stability and accuracy of the connection.

[0035] There are handles 22 on both sides of the base frame 1, and both sets of handles 22 are provided with handle covers 23. The design of the handles 22 allows the operator to easily hold and operate the loosening device, thereby improving the convenience and efficiency of the operation. The handle covers 23 cover the handles 22, providing a better grip, reducing hand fatigue during operation, and also increasing the safety of operation to prevent the hands from slipping or getting injured.

[0036] In this embodiment, the operator starts the motor 2, and the motor 2 drives the support rod 4 and the connecting rod 6 through the gear transmission system 3. The gear transmission system 3 drives the hinges 5 and the connecting rod 6 on both sides of the support rod 4 to move, thereby driving the mounting plate 7 and the loosening knife 8 to loosen the soil. The two groups of designs of the support rod 4 allow the device to be stably mounted on the base frame 1, and the flexible movement of the hinges 5 and the connecting rod 6 ensures that the loosening knife 8 can penetrate deep into the soil for effective loosening. The quick-install mechanism makes the installation and removal of the loosening knife 8 quick and convenient. The clamping rod 9 is arranged on the mounting plate 7, and the clamping groove 10 is located on the outer wall of the clamping rod 9. The clamping sleeve 11 and the clamping block 12 are used in conjunction with the rotary wheel 14 and the spring 15. The loosening knife 8 is quickly installed and removed. When the connecting rod 9 is on, the clamping block 12 will be pushed by the clamping rod 9 and rotate. When the position of the clamping block 12 corresponds to the position of the clamping groove 10, the spring 15 will push the locking sleeve 12 downward. At this time, the locking sleeve 12 presses one end of the clamping block 12 through the rotating wheel 14 to make the other end of the clamping block 12 embedded in the clamping groove 10, so that the clamping sleeve 11 can be fixed to the connecting rod 9. When the connecting rod 9 and the clamping sleeve 11 need to be separated, it is only necessary to move the locking sleeve 12 so that the rotating wheel 14 on the locking sleeve 12 is separated from the clamping block 12. At this time, the clamping block 12 is free from the restriction of the rotating wheel 14 and leaves the clamping groove 10, which can complete the separation of the clamping sleeve 11 and the connecting rod 9. The loosening knife 8 can be quickly fixed or released, and the limiting assembly further completes the installation and tightening of the loosening knife 8.

[0037] See also Figure 4 As an implementation method of the limit assembly: a limit assembly is provided on the snap sleeve 11, and the limit assembly includes a rotating sleeve 24, a vertical rod 25, a stop block 26, a limit sleeve 27 and a clearance groove 28. The rotating sleeve 24 is rotatably installed on the top of the lock sleeve 13, and the vertical rod 25 is provided with multiple groups installed on the top surface of the rotating sleeve 24. The stop block 26 is provided with multiple groups and is respectively installed on multiple groups of vertical rods 25. The limit sleeve 27 is installed on the top of the snap sleeve 11 and is fixedly connected to the top of the spring 15. The clearance groove 28 is provided on the limit sleeve 27. The design of the limit assembly further ensures the precise control of the working depth and position of the loosening knife 8. When the loosening knife 8 reaches the set depth, the stop block 26 will contact the limit sleeve 27 to prevent it from moving further.

[0038] The diameters of the multiple groups of stoppers 26 are all smaller than the clearance grooves 28. The clearance grooves 28 allow the stoppers 26 to have a certain amount of movement space when in the extreme position, thereby avoiding damage to the mechanism due to excessive pressure and improving the service life and reliability of the device.

[0039] More specifically, the rotating sleeve 24 is installed at the top of the locking sleeve 13, the vertical rod 25 is installed on the top surface of the rotating sleeve 24, the stop block 26 is installed on the vertical rod 25, the limit sleeve 27 is installed at the top of the clamping sleeve 11, and the clearance groove 28 is set on the limit sleeve 27. When the loosening knife 8 reaches a certain position, the stop block 26 will contact the limit sleeve 27 to prevent the loosening knife 8 from continuing to move, thereby limiting its working depth. The design of the clearance groove 28 allows the stop block 26 to have a certain amount of room for movement when it reaches the limit position, thereby avoiding damage to the mechanism due to excessive pressure.

[0040] In summary, when the overall equipment is in use or running: the operator starts the motor 2, and the motor 2 drives the support rod 4 and the connecting rod 6 through the gear transmission system 3. The gear transmission system 3 drives the hinges 5 and the connecting rod 6 on both sides of the support rod 4 to move, thereby driving the mounting plate 7 and the loosening knife 8 to loosen the soil. The two-group design of the support rod 4 allows the device to be stably mounted on the base frame 1, and the flexible movement of the hinges 5 and the connecting rod 6 ensures that the loosening knife 8 can penetrate deep into the soil for effective loosening. The quick-install mechanism makes the installation and removal of the loosening knife 8 quick and convenient. The clamping rod 9 is arranged on the mounting plate 7, and the clamping groove 10 is located on the outer wall of the clamping rod 9. The clamping sleeve 11 and the clamping block 12 are used in conjunction with the rotary wheel 14 and the spring 15 to achieve quick installation and removal of the loosening knife 8. When the clamping rod 9 is sleeved, the clamping block 12 will be pushed by the clamping rod 9 and rotate. When the position of the clamping block 12 corresponds to the position of the clamping groove 10, the spring 15 will push the locking sleeve 12 downward. At this time, the locking sleeve 12 presses one end of the clamping block 12 through the rotating wheel 14 to make the other end of the clamping block 12 embedded in the clamping groove 10, so that the clamping sleeve 11 can be fixed to the clamping rod 9. When the clamping rod 9 and the clamping sleeve 11 need to be separated, it is only necessary to move the locking sleeve 12 so that the rotating wheel 14 on the locking sleeve 12 is separated from the clamping block 12. At this time, the clamping block 12 is free from the restriction of the rotating wheel 14 and leaves the clamping groove 10, which can complete the separation of the clamping sleeve 11 and the clamping rod 9. The loosening knife 8 can be quickly fixed or released, and the limiting assembly further completes the installation and tightening of the loosening knife 8.

[0041] The rotating sleeve 24 is installed at the top of the locking sleeve 13, the vertical rod 25 is installed on the top surface of the rotating sleeve 24, the stop block 26 is installed on the vertical rod 25, the limit sleeve 27 is installed at the top of the clamping sleeve 11, and the clearance groove 28 is set on the limit sleeve 27. When the loosening knife 8 reaches a certain position, the stop block 26 will contact the limit sleeve 27 to prevent the loosening knife 8 from continuing to move, thereby limiting its working depth. The design of the clearance groove 28 allows the stop block 26 to have a certain amount of room for movement when it reaches the limit position, thereby avoiding damage to the mechanism due to excessive pressure.

[0042] In all the schemes mentioned above, the connection between the two components can be selected according to actual conditions by welding, bolt and nut connection, bolt or screw connection or other well-known connection methods, which will not be listed here one by one. In the above, all fixed connections are preferably welded.
