Description

Technical Field

[0001] This utility model relates to the field of soil loosening devices, specifically a soil loosening device for landscaping and greening maintenance. Background Technology

[0002] During the construction of gardens, some landscape plants are usually planted according to the local climate and characteristics to achieve the desired effect of garden greening. In the process of planting garden greening, it is usually necessary to loosen the soil so that the roots of the plants can attach quickly.

[0003] In the process of loosening soil for greening, in some narrow areas where it is not convenient for mechanized equipment to operate, farm tools such as rakes, hoes and shovels are usually used. When loosening soil with these farm tools, the long handles are used to generate torque and the work mainly relies on the arms, which is more physically demanding for workers.

[0004] To address the aforementioned issues, a search revealed Chinese patent CN220108624U, which discloses a soil-loosening device for landscaping. The device includes loosening teeth and a handle mounted on top of the loosening teeth. An extension rod is threaded to the top of the handle, and a connecting strip is movably hinged to the bottom of the handle. Multiple loosening teeth are movably engaged with the bottom of the connecting strip. A foot pedal is movably hinged to the back of the connecting strip, and the foot pedal is used to apply force by foot, causing the loosening teeth to lift and loosen the soil.

[0005] Although the above-mentioned device allows one foot to step on the foot pedal while the other foot is lifted, thus transferring the body's weight onto the foot pedal and causing it to move downwards, causing the front end of the loosening teeth to flip upwards to achieve the effect of loosening the soil, in actual use, when bearing weight on one foot, the body's center of gravity is biased to one side, making it easy to sway or even tip over. This is especially true when the soil is hard, requiring more force and increasing the risk of imbalance, which can easily lead to falls and injuries. Utility Model Content

[0006] The purpose of this utility model is to provide a soil loosening device for landscaping maintenance, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, a soil loosening device for landscaping maintenance is provided, comprising a soil loosening mechanism, a stable cutting mechanism at the end of the soil loosening mechanism, and a main frame structure installed on its upper side. A connecting frame is provided on the main frame structure, and a fixed frame is fixedly connected to the connecting frame. The soil loosening mechanism includes a diagonal support frame fixed to the bottom of the fixed frame, and a docking sleeve is provided at the bottom of the diagonal support frame. A fixed plowing plate and a movable plowing plate are installed at the bottom of the docking sleeve.

[0008] Furthermore, the connecting frame is U-shaped, and the main shaft is connected inside the connecting frame via bearings. The fixed frame is provided with a connecting column, and a handle is fixed to the end of the connecting column. The handle is T-shaped.

[0009] Furthermore, the soil loosening mechanism also includes a support base, which is fixed to the bottom of the inclined support frame. Two sets of the inclined support frame are arranged in parallel at the bottom of the main frame structure, and multiple sets of tie rods are connected between the two sets of the inclined support frame.

[0010] Furthermore, a reinforcing frame is fixed at the bottom of the diagonal brace, and a fixed frame is connected to the top of the reinforcing frame. The diagonal brace, the reinforcing frame, and the fixed frame are arranged in a triangular pattern.

[0011] Furthermore, a mating sleeve is inserted at the bottom of the support base, and a U-shaped hole is opened on the outside of the mating sleeve. At the same time, multiple sets of studs are inserted inside the U-shaped hole. The studs are fixed to the end of the support base, and a fixing nut is screwed to the end of the stud.

[0012] Furthermore, the bottom sides of the docking sleeve are respectively connected to a loosening column and an adjusting sleeve, and multiple sets of fixed plowing plates are equidistantly arranged on the loosening column, while a movable plowing plate is provided on one side of the adjusting sleeve.

[0013] Furthermore, both the movable and fixed plowing plates are V-shaped, and their ends are tapered. The upper and lower parts of the adjusting sleeve are fixed with adjusting tracks, and locking pins are inserted inside the adjusting tracks. An adjusting pin is fixed at the end of the locking pin, and the adjusting pin is inserted inside the adjusting sleeve. At the same time, the movable plowing plate is fixed at the end of the adjusting pin.

[0014] Furthermore, the stable cutting mechanism includes an end plate, which is circular in shape. A main shaft is fixed on the end plate, and multiple sets of docking posts are equidistantly arranged on the inner side of the end plate. A transverse cutting blade is fixed on each of the multiple sets of docking posts, and multiple sets of longitudinal cutting blades are equidistantly arranged on the transverse cutting blades. Multiple sets of openings are opened on the longitudinal cutting blades.

[0015] Furthermore, the longitudinal cutting blade is annular, the transverse cutting blade is rectangular, both the transverse and longitudinal cutting blades have blades at their ends, and the angle between the transverse and longitudinal cutting blades is 90 degrees.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This solution utilizes a triangular distribution structure formed by the main frame, diagonal bracing, and reinforcing frame, along with multiple sets of tie rods connecting the two sets of parallel diagonal bracing, to significantly improve the overall stability and load-bearing capacity of the structure. During operation, it can effectively distribute the force, preventing structural swaying when large forces are required due to hard soil. The loosening operation can be completed stably through the equipment's own structure without relying on single-leg footing for load-bearing, fundamentally solving the problem of body center of gravity shift caused by single-leg weight-bearing and reducing the risk of swaying, tipping, and falls.

[0018] 2. This solution provides space for the stud to be adjusted up and down through the U-shaped hole on the outside of the docking sleeve. The operator can loosen the fixing nut at the end of the stud and move the docking sleeve up and down along the U-shaped hole, thereby driving the fixed plowing plate and the movable plowing plate connected to the docking sleeve to adjust their height synchronously. This easily achieves precise control of the plowing depth, adapting to different soil types, such as soft soil and hard compacted soil, and operational needs, such as shallow tillage and deep tillage, greatly improving the versatility and applicability of the equipment.

[0019] 3. This solution uses locking posts inserted inside the adjustment tracks fixed at the upper and lower parts of the adjustment sleeve. The adjustment post at the end of the locking post is inserted inside the adjustment sleeve and the end is fixed to the movable ploughing piece. By adjusting the position of the locking post in the adjustment track, the adjustment post can be moved, thereby adjusting the distance between the movable ploughing piece and the fixed ploughing piece to adapt to different soil conditions and soil loosening needs.

Detailed Implementation

[0030] Please see Figures 1-9 This utility model provides a soil loosening device for garden greening maintenance, including a soil loosening mechanism 200. The soil loosening mechanism 200 has a stable cutting mechanism 300 at its end, and a main frame structure 100 is installed on its upper side. The main frame structure 100 has a connecting frame 11, and a fixed frame 12 is fixedly connected to the connecting frame 11. The soil loosening mechanism 200 includes a diagonal support frame 21 fixed to the bottom of the fixed frame 12, and a docking sleeve 24 is provided at the bottom of the diagonal support frame 21. A fixed plowing plate 28 and a movable plowing plate 29 are installed at the bottom of the docking sleeve 24.

[0031] In a preferred embodiment, the connecting frame 11 is U-shaped, and the main shaft 31 is connected to the inside of the connecting frame 11 through a bearing. The fixed frame 12 is provided with a connecting column 13, and a handle 14 is fixed to the end of the connecting column 13. The handle 14 is T-shaped.

[0032] The soil loosening mechanism 200 also includes a support base 23, which is fixed to the bottom of the inclined support frame 21. Two sets of inclined support frames 21 are arranged in parallel at the bottom of the main frame structure 100, and multiple sets of tie rods 22 are connected between the two sets of inclined support frames 21.

[0033] The bottom of the diagonal brace 21 is fixed with a reinforcing frame 210, and the top of the reinforcing frame 210 is connected to a fixed frame 12. The diagonal brace 21, the reinforcing frame 210 and the fixed frame 12 are arranged in a triangular pattern.

[0034] A mating sleeve 24 is inserted at the bottom of the support base 23, and a U-shaped hole 25 is opened on the outside of the mating sleeve 24. At the same time, multiple sets of studs 26 are inserted inside the U-shaped hole 25. The studs 26 are fixed to the end of the support base 23, and a fixing nut is screwed to the end of the stud 26.

[0035] like Figure 1 and Figures 5-6As shown: The bottom of the diagonal brace 21 is also fixed with a support base 23. The outer side of the mating sleeve 24 inserted at the bottom of the support base 23 has a U-shaped hole 25. Multiple sets of studs 26 inserted inside the U-shaped hole 25 are fixed to the end of the support base 23. The mating sleeve 24 can be firmly limited by the fixing nut at the end of the stud 26.

[0036] The U-shaped hole 25 on the outside of the connecting sleeve 24 provides space for the stud 26 to be adjusted up and down. The operator can loosen the fixing nut at the end of the stud 26 and move the connecting sleeve 24 up and down along the U-shaped hole 25. This will drive the fixed plowing plate 28 and the movable plowing plate 29 connected to the connecting sleeve 24 to adjust their height synchronously, easily achieving precise control of the plowing depth. This adapts to different soil types, such as soft soil and hard compacted soil, and to different operational needs, such as shallow tillage and deep tillage, greatly improving the versatility and applicability of the equipment. During the adjustment process, the structural design of the U-shaped hole 25 can precisely limit the movement trajectory of the connecting sleeve 24 to avoid deviation during adjustment. Combined with the stable locking of the stud 26 and the fixing nut, it can ensure that the plowing depth remains stable after adjustment. During operation, there will be no displacement due to soil resistance or equipment vibration, ensuring the uniformity and consistency of the soil loosening operation.

[0037] Depth adjustment can be completed without disassembling the equipment, making operation convenient and efficient, reducing the labor intensity of operators, while adapting to the needs of different farming scenarios, reducing the cost of replacing equipment due to changes in operational needs, and improving overall operational efficiency and economy; by precisely adjusting the plowing depth, the loosening range can be controlled according to the crop planting needs, avoiding incomplete improvement of soil compaction due to excessively shallow loosening, or loss of soil nutrients due to excessively deep loosening, thus ensuring the loosening effect and benefiting subsequent crop growth, improving the practicality and reliability of agricultural production.

[0038] The bottom sides of the connecting sleeve 24 are respectively connected to the loosening column 27 and the adjusting sleeve 292, and multiple sets of fixed plowing plates 28 are equidistantly arranged on the loosening column 27, and a movable plowing plate 29 is provided on one side of the adjusting sleeve 292.

[0039] Both the movable plowing piece 29 and the fixed plowing piece 28 are V-shaped, and their ends are tapered. The upper and lower parts of the adjusting sleeve 292 are fixed with adjusting rails 293, and a locking post 294 is inserted inside the adjusting rails 293. An adjusting post 291 is fixed at the end of the locking post 294, and the adjusting post 291 is inserted inside the adjusting sleeve 292. At the same time, the movable plowing piece 29 is fixed at the end of the adjusting post 291.

[0040] Working principle: During use, the main frame structure 100 serves as the core supporting component. The soil loosening mechanism 200 installed at its end is responsible for completing the soil loosening operation. The stabilizing cutting mechanism 300 assembled at its front can assist in breaking up soil clods and improve the soil breaking effect. The fixed frame 12 fixed on the connecting frame 11 is not only fixed to the "T"-shaped handle 14 through the connecting column 13, making it convenient for the operator to hold and adjust, but also provides the installation foundation for other components of the soil loosening mechanism 200. In the soil loosening mechanism 200, two sets of diagonal braces 21 are arranged in parallel at the bottom of the fixed frame 12. Multiple sets of tie rods 22 connected between the two sets of diagonal braces 21 enhance the structural stability. The top of the reinforcing frame 210 fixed at the bottom of the diagonal brace 21 is connected to the fixed frame 12, so that the diagonal brace 21, the reinforcing frame 210 and the fixed frame 12 form a triangle. The distribution further enhances the overall structural strength. The bottom sides of the connecting sleeve 24 are connected to the loosening column 27 and the adjusting sleeve 292, respectively. Multiple sets of fixed plowing plates 28 are equidistantly arranged on the loosening column 27 and cooperate with the movable plowing plate 29 on one side of the adjusting sleeve 292. Both are V-shaped and tapered at the end, which can efficiently cut into the soil for loosening operations. The adjusting track 293 fixed at the upper and lower parts of the adjusting sleeve 292 has a locking column 294 inserted inside. The adjusting column 291 at the end of the locking column 294 is inserted inside the adjusting sleeve 292 and the movable plowing plate 29 is fixed at the end. By adjusting the position of the locking column 294 in the adjusting track 293, the adjusting column 291 can be moved, thereby adjusting the distance between the movable plowing plate 29 and the fixed plowing plate 28 to adapt to different soil conditions and loosening needs.

[0041] The overall structure features a triangular distribution design and multiple sets of reinforcing ribs 22, providing excellent stability and load-bearing capacity, making it resistant to deformation and damage during operation. The "V"-shaped plowing blades with tapered ends enhance soil breaking and loosening efficiency, while the adjustable function of the movable plowing blades 29 increases the equipment's versatility, adapting to various operating scenarios. The handle 14 facilitates operator control, and the overall assembly is reasonable and easy to operate, effectively improving the quality and efficiency of soil loosening operations.

[0042] In a preferred embodiment, the stabilizing cutting mechanism 300 includes an end piece 32, which is circular. A main shaft 31 is fixed on the end piece 32, and multiple sets of docking posts 33 are equidistantly arranged on the inner side of the end piece 32. A transverse cutting blade 35 is fixed on each of the multiple sets of docking posts 33, and multiple sets of longitudinal cutting blades 34 are equidistantly arranged on the transverse cutting blades 35. Multiple sets of openings 341 are opened on the longitudinal cutting blades 34.

[0043] The longitudinal cutting blade 34 is ring-shaped, and the transverse cutting blade 35 is rectangular. Both the transverse cutting blade 35 and the longitudinal cutting blade 34 have cutting edges at their ends, and the included angle between the transverse cutting blade 35 and the longitudinal cutting blade 34 is 90 degrees.

[0044] like Figures 1-5As shown: The triangular distribution structure formed by the main frame structure 100, the diagonal bracing frame 21, and the reinforcing frame 210, along with multiple sets of tie rods 22 connecting the two sets of parallel diagonal bracing frames 21, significantly improves the overall stability and load-bearing capacity of the structure. During operation, it effectively distributes the force, preventing structural swaying when applying significant force due to hard soil. The equipment can stably complete soil loosening operations without relying on single-leg weight-bearing, fundamentally solving the problem of body center of gravity shift caused by single-leg weight-bearing and reducing the risk of swaying, tipping, and falls. The support base 23 is securely connected to the U-shaped hole 25 of the connecting sleeve 24 via studs 26, further strengthening... The structural stability during operation ensures the overall stability of the equipment, even when working in hard soil where significant resistance needs to be overcome, preventing imbalance caused by uneven force. The fixed plowing blade 28 and movable plowing blade 29, which are V-shaped and tapered at the ends, can cut into hard soil more efficiently, reducing the external force required for operation and lowering the possibility of loss of balance due to excessive force. At the same time, the adjustable column 291, adjustable sleeve 292 and locking column 294 work together to adjust the spacing of the movable plowing blade 29, which can be adapted to the optimal loosening spacing according to the hardness of the soil, further reducing operating resistance and difficulty, and indirectly improving operational safety.

[0045] The "T"-shaped handle 14 makes it easy for operators to grip and control. Combined with the stable overall structure, it allows operators to maintain their balance during operation without relying on single-leg weight-bearing. This completely avoids the risk of imbalance when stepping on one foot with traditional equipment, ensuring the personal safety of operators and improving the efficiency and quality of soil loosening operations.
