Description

Technical Field

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

[0002] To improve soil quality and increase crop yield, it is necessary to loosen the soil regularly or before each crop sowing season. Loosening the soil can improve soil structure, allow air circulation, and increase soil temperature.

[0003] Currently, soil loosening is typically carried out using soil loosening machines. Existing soil loosening machines mainly consist of an engine, reduction gears, a walking mechanism, and loosening shovels. The engine provides power and is connected to the reduction gear shaft via a coupling. The loosening shovels are used to agitate the soil, thus loosening it.

[0004] Soil loosening machines can effectively improve planting efficiency and reduce people's workload. The device that plays a working role is the soil loosening shovel. Existing soil loosening shovels are usually shovel-shaped structures with an arc cross-section. When working, they will come into direct contact with the soil. When shoveling harder soil, the soil loosening shovel will bear a lot of force. After frequent use, the soil loosening shovel is prone to deformation and damage, and its durability is poor. Utility Model Content

[0005] The purpose of this utility model is to provide a soil loosening device to solve the above-mentioned problems.

[0006] This utility model achieves the above-mentioned objective through the following technical solution: a soil loosening device, including a connecting arm, a soil loosening shovel provided on the connecting arm, the connecting arm including a plurality of connecting seats, a plurality of connecting parts rotatably connected inside the connecting seats provided on the soil loosening shovel, a support rod provided on the connecting seat, tension springs connected to both ends of the support rod, a bracket provided on the soil loosening shovel, a plurality of lifting rings provided on the bracket, and the end of the tension spring away from the support rod connected to the lifting ring.

[0007] As a further feature of this utility model, one end of the tension spring is provided with a first hook and the other end is provided with a second hook. The first hook is engaged with the lifting ring. Both ends of the support rod are provided with connecting shafts. A limiting ring is sleeved on the connecting shaft. The second hook is used to engage between the limiting ring and the support rod. A locking pin is provided on the connecting shaft to limit the limiting ring.

[0008] As a further feature of this invention, each of the connecting shafts is provided with a socket for inserting a locking pin.

[0009] As a further feature of this invention, the lifting ring is provided with a threaded rod, the bracket is provided with several through holes for the threaded rod to pass through, and the threaded rod is threadedly connected with a fastening sleeve.

[0010] As a further feature of this invention, the loosening shovel is provided with a reinforcing plate, which is fixedly connected to the loosening shovel by a connecting assembly, which includes a bolt and a nut for matching the bolt.

[0011] As a further feature of this invention, the reinforcing sheet is made of stainless steel.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] When the soil is moved by the loosening shovel, the soil exerts a thrust on the shovel in the opposite direction. The shovel is deflected by the force, causing the connecting piece to rotate inside the connecting seat. This pulls on the tension spring, causing it to stretch and deform to cushion the impact. After the soil is loosened, the shovel is freed from the external force, and the tension spring automatically contracts and returns to its original shape, thus resetting the shovel. This design allows the shovel to actively rotate and buffer when subjected to force, without directly resisting the external force, thereby preventing deformation and damage to the shovel and improving its durability.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1As shown, a soil loosening device includes a connecting arm 1, on which a soil loosening shovel 2 is mounted. The connecting arm 1 includes several connecting seats 3. Several connecting parts rotatably connected to the connecting seats 3 are mounted on the soil loosening shovel 2. A support rod 4 is mounted on the connecting seat 3, and tension springs 5 ​​are connected to both ends of the support rod 4. A bracket 6 is mounted on the soil loosening shovel 2, and several lifting rings 7 are mounted on the bracket 6. The end of the tension spring 5 away from the support rod 4 is connected to the lifting ring 7. Therefore, when the soil loosening shovel 2 scoops the soil, the soil will be applied in the opposite direction to the soil loosening shovel 2. When a thrust is applied, the loosening shovel 2 will deflect accordingly, causing the connecting piece to rotate inside the connecting seat 3. This will pull the tension spring 5, causing it to stretch and deform to cushion the impact. After the soil is loosened, the loosening shovel 2 will be freed from the external force, and the tension spring 5 will automatically contract and return to its original shape, thus causing the loosening shovel 2 to reset. This design allows the loosening shovel 2 to actively rotate and buffer when subjected to force, without directly resisting the external force, thereby preventing deformation and damage to the loosening shovel 2 and improving its durability.

[0020] Please see Figure 1-3 As shown, a first hook 8 is provided at one end of the tension spring 5, and a second hook 9 is provided at the other end. The first hook 8 is engaged with the lifting ring 7. A connecting shaft 10 is provided at both ends of the support rod 4, and a limiting ring 11 is sleeved on the connecting shaft 10. The second hook 9 is used to engage between the limiting ring 11 and the support rod 4. A locking pin 12 is provided on the connecting shaft 10 to limit the limiting ring 11. Therefore, when installing the tension spring 5, the first hook 8 can be engaged with the lifting ring 7 first. Then remove the limiting ring 11, fasten the second hook 9 into the connecting shaft 10, and then put the limiting ring 11 back onto the connecting shaft 10. The locking pin 12 is used to secure the second hook 9 between the limiting ring 11 and the support rod 4, thus installing the tension spring 5. When it is necessary to remove the tension spring 5, first remove the locking pin 12, then remove the limiting ring 11, then remove the second hook 9 from the connecting shaft 10, and finally remove the first hook 8 from the lifting ring. The tension spring 5 can be removed by disengaging it from the inner part of the ring 7. This design makes the disassembly and assembly of the tension spring 5 convenient, allowing for replacement and extending the service life of the device. The connecting shaft 10 has holes for inserting the locking pin 12. By inserting the locking pin 12 into the holes, the locking pin 12 is fixed to the connecting shaft 10. The locking pin 12 blocks the limiting ring 11, preventing it from falling off the connecting shaft 10 and ensuring its restraining effect. A threaded rod 13 is provided on the lifting ring 7, and several through holes are provided on the bracket 6 for the threaded rod 13 to pass through. A fastening sleeve 14 is threaded onto the threaded rod 13. When the lifting ring 7 needs to be replaced, the fastening sleeve 14 can be unscrewed from the threaded rod 13, and the threaded rod 13 can be pulled out of the through holes to remove the lifting ring 7 and replace it with a new one. The operation is convenient and simple.

[0021] Please see Figure 1 As shown, a reinforcing plate 15 is provided on the loosening shovel 2. The reinforcing plate 15 is fixedly connected to the loosening shovel 2 by a connecting assembly, which includes bolts and nuts for matching the bolts. By providing the reinforcing plate 15, the structural strength and durability of the loosening shovel 2 can be improved. Since the reinforcing plate 15 is detachable, it can be replaced, further extending the service life of the loosening shovel 2. The reinforcing plate 15 is made of stainless steel, which has high strength and hardness, is not easy to rust, and has good durability.
