Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and in particular to a soil loosening device for horticulture. Background Technology

[0002] In horticulture, home garden maintenance, and small nursery management, loosening the soil is a key step in ensuring plant root respiration and promoting nutrient absorption. Therefore, horticultural soil loosening devices have become an indispensable tool.

[0003] Regarding the aforementioned and existing related technologies, the inventors believe that the following defects often exist: In existing horticultural soil loosening devices, the operating rods mostly adopt a one-piece molded fixed structure. For users of different heights or different working scenarios, the fixed structure of the operating rod can easily cause users to bend over excessively or have unbalanced arm force, which not only reduces the comfort of operation but also affects the soil loosening efficiency. On the other hand, the connection method of the soil loosening rod is mostly welding or one-piece injection molding. When it is necessary to replace the soil loosening rod, it is not possible to replace the damaged soil loosening rod individually. The soil loosening rod can only be replaced as a whole, which not only increases the operating cost of the equipment but also wastes the resources of the undamaged operating rod. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the existing technology has the disadvantages of low operating comfort and affected soil loosening efficiency due to the fixed structure of the operating rod in the horticultural soil loosening device, and the high replacement cost and waste of resources due to the connection method of the soil loosening rod. Therefore, we propose a horticultural soil loosening device.

[0005] To achieve the above objectives, this application adopts the following technical solution: a horticultural soil loosening device, comprising a base frame, a reinforcing frame fixed to the top of the base frame, a height-adjustable operating lever assembly provided on the top of the reinforcing frame, a handle assembly provided on the top of the operating lever assembly, and a insert rod assembly provided at the bottom of the base frame. The operating lever assembly includes an outer rod and an inner rod, the inner rod sliding inside the outer rod, and an adjustment hole provided on the surface of the inner rod. The number of adjustment holes is multiple and arranged longitudinally at equal intervals. A first fastening bolt is provided on the outer rod. One end of the first fastening bolt passes through the outer rod and is threadedly connected to the inner thread of the adjustment hole. The height of the inner rod is fixed by the first fastening bolt and the adjustment hole. The insertion rod assembly includes a soil loosening insertion rod, a limiting ring, and a second fastening bolt. The number of soil loosening insertion rods, limiting rings, and second fastening bolts is multiple and distributed in a rectangular array. The surface of the base frame has multiple insertion holes that match the second fastening bolts. The second fastening bolts are movably inserted into the insertion holes. The bottom end of the second fastening bolt is threadedly connected to the top end of the soil loosening insertion rod. The limiting ring is fixed to the outer surface of the top of the soil loosening insertion rod.

[0006] Preferably, the handle assembly includes a handle frame and a handle sleeve, the bottom of the handle frame is fixed to the top of the inner rod, and the handle sleeve is two in number and fixed on both sides of the handle frame respectively.

[0007] Preferably, the top of the loosening rod has a threaded groove that matches the bottom end of the second fastening bolt.

[0014] Based on the technical solution of this utility model, without changing the essential spirit of this utility model, those skilled in the art can propose various interchangeable structural methods and implementation methods. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model, and should not be regarded as the entirety of this utility model or as a limitation or restriction of the technical solution of this utility model.

[0015] Refer to Figure 1- Figure 4 As shown, this utility model provides a technical solution: a horticultural soil loosening device, including a base frame 1, a reinforcing frame 2 fixed to the top of the base frame 1, a height-adjustable operating rod assembly 3 provided on the top of the reinforcing frame 2, a handle assembly 4 provided on the top of the operating rod assembly 3, and a plug assembly 5 provided at the bottom of the base frame 1. The operating rod assembly 3 includes an outer rod 301 and an inner rod 302, the inner rod 302 sliding inside the outer rod 301, and adjustment holes 303 formed on the surface of the inner rod 302. The number of adjustment holes 303 is multiple and arranged longitudinally at equal intervals. The outer rod 301 is provided with a first fastening bolt 304. One end of the first fastening bolt 304 passes through the outer rod 301 and is threadedly connected to the inner thread of the adjustment hole 303. The height of the inner rod 302 is fixed by the first fastening bolt 304 and the adjustment hole 303. The insertion rod assembly 5 includes a soil loosening insertion rod 501, a limiting ring 502 and a second fastening bolt 503. There are multiple soil loosening insertion rods 501, limiting rings 502 and second fastening bolts 503, which are distributed in a rectangular array. The surface of the base frame 1 is provided with multiple insertion holes 504 that match the second fastening bolts 503. The second fastening bolts 503 are movably inserted into the insertion holes 504. The bottom end of the second fastening bolts 503 is threadedly connected to the top end of the soil loosening insertion rod 501. The limiting ring 502 is fixed to the outer surface of the top of the soil loosening insertion rod 501. Specifically: By setting up a height-adjustable operating lever assembly 3, users can flexibly adjust the height of the operating lever according to their own height or the needs of the work scenario. When it is necessary to raise the operating lever, simply loosen the first fastening bolt 304, slide the inner rod 302 upward to the appropriate height, align the corresponding adjustment hole 303 with the first fastening bolt 304, and then tighten the first fastening bolt 304 to fix the position of the inner rod 302. To lower the operating lever height, reverse the above steps. This adjustable design effectively avoids the problem of excessive bending of the user and imbalance of arm force caused by the fixed structure of the operating lever, greatly improving the operating comfort and soil loosening efficiency. At the same time, the insertion rod assembly 5 is a detachable design. When a soil loosening insertion rod 501 is damaged, it is not necessary to replace the entire insertion rod assembly 5. Simply loosen the second fastening bolt 503, remove the damaged soil loosening insertion rod 501 from the base frame 1, replace it with a new soil loosening insertion rod 501, and re-tighten the second fastening bolt 503. Once secured, it not only reduces the cost of using the equipment but also avoids wasting resources by not damaging the operating lever. In addition, the addition of the reinforcing frame 2 enhances the structural stability of the entire device, enabling it to better withstand the reaction force of the soil during the loosening process and ensuring the smooth progress of the operation.

[0016] Reference Figure 2 As shown, in this embodiment: the handle assembly 4 includes a handle frame 401 and a handle glove 402. The bottom of the handle frame 401 is fixed to the top of the inner rod 302. There are two handle gloves 402, which are fixed on both sides of the handle frame 401 respectively. The surface of the handle gloves 402 is provided with anti-slip threads and distributed along the axial direction of the handle gloves 402. Specifically, by setting handle gloves 402 on both sides of the handle frame 401, and the surface of the handle gloves 402 has anti-slip threads distributed along the axial direction, when the user holds the handle assembly 4 to perform soil loosening operations, the anti-slip threads can increase the friction between the hand and the handle gloves 402, preventing the hand from slipping during operation and affecting the control of the device. Even when the hands are wet or muddy, a stable grip can be guaranteed, further improving the convenience and safety of operation.

[0017] Reference Figure 4 As shown, in this embodiment: the top of the loosening rod 501 is provided with a threaded groove 505 that matches the bottom end of the second fastening bolt 503, and a pad 6 is fixedly provided at the bottom of the base frame 1. The pad 6 is located between the limiting ring 502 and the base frame 1, and the top of the limiting ring 502 abuts against the bottom of the pad 6. Specifically: By creating a threaded groove 505 at the top of the loosening rod 501 that matches the bottom of the second fastening bolt 503, the second fastening bolt 503 can pass through the base frame 1 and the pad 6 to more securely connect with the loosening rod 501. This avoids the problem of the loosening rod 501 shaking or falling off due to the second fastening bolt 503 loosening during use, ensuring the stability of the loosening operation. The pad 6, fixedly installed at the bottom of the base frame 1, is located between the limiting ring 502 and the base frame 1, with the top of the limiting ring 502 abutting against the bottom of the pad 6. The pad 6 plays a role in buffering and supporting. When the loosening rod 501 is inserted into the soil and receives a reaction force, the pad 6 can disperse some of the force, reducing the direct impact of the limiting ring 502 on the base frame 1, extending the service life of the device, and making the entire device more stable during operation.

[0018] Referring to Figure 1, in this embodiment: an elastic washer 305 is fitted onto the surface of the first fastening bolt 304; Specifically: When the first fastening bolt 304 is tightened to fix the inner rod 302, the elastic washer 305 undergoes elastic deformation, filling the tiny gaps between the first fastening bolt 304 and the contact surfaces of the outer rod 301 and the adjusting hole 303. This not only increases the tightness of the connection of the first fastening bolt 304, preventing it from loosening due to device vibration during use and ensuring the stability of the operating lever assembly 3 after height adjustment, but also provides a certain buffering effect, reducing the rigidity between the first fastening bolt 304 and the contact surface. Friction reduces wear and extends the service life of various components.

[0019] Working Principle: The user grips the handle assembly 4 and, depending on their height or the work environment, first loosens the first fastening bolt 304. At this time, the elastic washer 305 recovers some elasticity, reducing resistance during loosening. The inner rod 302 is then slid up or down to a suitable height, aligning the corresponding adjustment hole 303 with the first fastening bolt 304. The first fastening bolt 304 is then tightened. During tightening, the elastic washer 305 is compressed, filling the small gaps between the first fastening bolt 304, the outer rod 301, and the adjustment hole 303, fixing the position of the inner rod 302. After determining the operating rod height, the device is moved to the area requiring soil loosening. The loosening rod 501 is aligned with the soil, and the handle assembly 4 is pressed down forcefully to insert the loosening rod 501 into the soil for loosening operations. During the loosening process, the reinforcing frame 2 enhances the structural stability of the entire device, enabling it to better withstand the reaction force of the soil. If a certain loosening rod 501... If damage occurs, simply loosen the second fastening bolt 503 and remove the damaged loosening rod 501 from the base frame 1. During this process, the pad 6 acts as a buffer to reduce the direct impact of the limiting ring 502 on the base frame 1. Then replace it with a new loosening rod 501, align the bottom end of the second fastening bolt 503 with the threaded groove 505 on the top of the new loosening rod 501 and tighten it. Once it is re-fixed, the loosening operation can continue.

[0020] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
