Description

Technical Field

[0001] This utility model relates to the technical field of supporting equipment for garden planting, specifically to a soil leveling device for garden planting. Background Technology

[0002] Traditional soil leveling devices for landscaping typically use a single scraper, which is driven by a traction machine to level the soil. The improved soil leveling device is a combination structure of a single row of loosening shovels and a scraper. The loosening shovels are arranged in a row in front of the scraper. The loosening shovels are driven by a traction machine to insert into the soil to loosen it, and then the scraper levels the loosened soil.

[0003] Although the traditional single-row loosening shovel has a simple structure, it has the following technical bottlenecks in practical applications: the single-row loosening shovel can only cut into the soil at a fixed depth. If the loosening is too shallow, the deep compacted soil cannot be effectively broken up; if the loosening is too deep, the operating resistance is concentrated. In hard or severely compacted soil, the single-row loosening shovel has to overcome the resistance of the entire soil layer at once, which leads to a sharp increase in the traction load of the equipment, and may even cause the loosening shovel to deform or the power system to overload.

[0004] Therefore, we propose a soil leveling device for garden planting. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a soil leveling device for garden planting. It overcomes the deficiencies of existing technologies, has a reasonable design, is easy to adjust, and solves the technical problems of high resistance, deformation of the loosening shovel, or overload of the power system when using existing soil leveling devices.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A soil leveling device for garden planting, characterized in that it includes a connecting frame and a soil loosening mechanism and a leveling mechanism installed on the front and rear sides of the connecting frame;

[0010] The soil loosening mechanism includes soil loosening shovels arranged in a rectangular array below the connecting frame. Each soil loosening shovel in the same row is fixed to the same lower crossbeam. The lower crossbeam is movably installed below the connecting frame and its installation height is adjustable. The soil loosening shovels in the rear row are lower than those in the front row.

[0011] Furthermore, the base of the connecting frame is composed of an upper crossbeam and an upper longitudinal beam forming a frame structure. Below each upper crossbeam of the base is a lower crossbeam. Vertically extending end screws and middle screws are installed in the two end areas and the middle area of ​​the lower crossbeam. Vertically extending end holes and middle holes are installed in the two end areas and the middle area of ​​the upper crossbeam. The end screws pass through the end holes. A spring is sleeved on the part of the end screw located between the upper and lower crossbeams. A limiting nut that presses against the upper surface of the upper crossbeam is threaded onto the upper part of the end screw. The middle screw passes through the middle hole. Locking nuts that press against the upper and lower surfaces of the upper crossbeam are threaded onto the middle screw.

[0012] Furthermore, insert blocks are installed at both ends and in the middle of the lower crossbeam, and the end screws and the middle screws are threadedly connected to the corresponding insert blocks.

[0013] Furthermore, the limiting nut on the end screw is replaced by a rotary joint. The rotary joint has a hexagonal screwing part at the top, an outer annular limiting part extending radially outward at the bottom, and a threaded through hole running from top to bottom at the center.

[0015] (III) Beneficial Effects

[0016] This utility model provides a soil leveling device for garden planting, which has the following beneficial effects:

[0017] 1. Differentiated configuration of soil loosening shovel depth in front and rear rows: shallow loosening in the front row breaks up the surface hard shell, while deep loosening in the rear row penetrates the compacted layer, achieving progressive soil breaking in layers.

[0018] 2. Coaxial straight layout: The front and rear shovels correspond one-to-one, ensuring that the rear deep loosening shovels work along the loosened area of ​​the front row, minimizing cutting resistance.

[0019] 3. Front and rear load distribution: The front and rear shovels share the soil loosening load in stages, reducing or avoiding deformation of the shovels and overload of the power system, thus improving the stability of equipment operation. Attached Figure Description

[0047] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0048] See attached document Figure 1-4 A soil leveling device for garden planting, characterized in that it includes a connecting frame 1 and a soil loosening mechanism 2 and a leveling mechanism 3 installed on the front and rear sides of the connecting frame 1.

[0049] The soil loosening mechanism 2 includes soil loosening shovels 21 arranged in a rectangular array below the connecting frame 1, that is, each soil loosening shovel in the front row corresponds to each soil loosening shovel in the back row. Each soil loosening shovel 21 in the same row is fixed on the same lower crossbeam 22. The lower crossbeam 22 is movably installed below the connecting frame 1 and its installation height is adjustable. The soil loosening shovels 21 in the back row are lower than the soil loosening shovels 21 in the front row.

[0050] The scraper 33 mechanism includes an end plate 31, side plates 32 integrally formed on both sides of the end plate 31, and a scraper 33 detachably installed at the bottom of the end plate 31. The side plates 32 on both sides are connected to the connecting frame 1 through connecting arms 34.

[0051] In this embodiment, the base of the connecting frame 1 is a rectangular frame structure composed of a pair of upper crossbeams 11 and four upper longitudinal beams 12. Each upper crossbeam 11 of the base is provided with a lower crossbeam 22. The two ends and the middle of the lower crossbeam 22 are equipped with vertically extending end screws 23 and middle screws 27. The two ends and the middle of the upper crossbeam 11 are equipped with vertically extending end through holes 13 and middle through holes. The end screws 23 pass through the end through holes 13. A spring 24 is sleeved on the part of the end screw 23 located between the upper crossbeam 11 and the lower crossbeam 22. The upper part of the spring screw 24 is threadedly connected to a limiting nut 25 that is pressed onto the upper surface of the upper crossbeam 11. The middle screw 27 passes through the middle through hole. The middle screw 27 is threadedly connected to a locking nut 28 that is pressed onto the upper and lower surfaces of the upper crossbeam 11. Additionally, a backrest bracket (not shown in the figure) can be installed on the side of the base near the leveling mechanism 3. The base and the backrest bracket form an L-shaped structure, which provides stable support after the base is tilted, facilitating the adjustment of the relative position of the loosening shovel 21. When adjusting the relative position of the loosening shovel 21, tilt the base to the side with the loosening shovel 21 bent upwards, loosen the upper and lower locking nuts 28 on the middle screw 27, and simultaneously tighten the limiting nuts 25 on the end screws 23 on both sides (if there are double limiting nuts 25, the upper limiting nut 25 needs to be loosened). Adjust the relative position of the lower crossbeam 22 and the loosening shovel 21. The spring 24 is in a compressed state, which facilitates pushing the lower crossbeam 22 outwards. Then tighten the locking nuts 28.

[0052] In this embodiment, insert blocks 26 are installed at both ends and in the middle of the lower crossbeam 22, and the end screws 23 and the middle screws 27 are threadedly connected to the corresponding insert blocks 26. By setting the insert blocks 26, the strength of the lower crossbeam 22 is improved and its service life is extended.

[0053] In other embodiments, the limiting nut 25 on the end screw 23 is replaced by a rotary joint 29. The rotary joint 29 has a hexagonal screwing part at the top, an outer annular limiting part 291 extending radially outward at the bottom, and a threaded through hole running from top to bottom at the center. A threaded sleeve 14 coaxial with the end through hole 13 is welded and fixed on the upper crossbeam 11. The annular limiting part 291 is installed in the threaded sleeve 14. A locking cap 15 is threadedly connected to the threaded sleeve 14. The top of the locking cap 15 has an inner annular limiting part 291 extending radially inward. The inner annular limiting part 291 is used to limit the outer annular limiting part 291. The screwing part is exposed outside the locking cap. The rotary joint 29 is threadedly connected to the end screw 23 through the threaded through hole. That is, through the cooperation of the outer ring-shaped limiting part 291, the threaded sleeve 14 and the locking cap 15, the rotary joint 29 is rotated and supported on the upper crossbeam 11. Loosen the locking nuts 28 on the upper and lower parts of the middle screw 27, attach the handle with the hexagonal perforation in the center to the screwing part of the rotary joint 29, and rotate the handle (the rotary joints 29 on both sides rotate synchronously) to achieve rapid adjustment of the relative height of the upper crossbeam 11 and the lower crossbeam 22, that is, to achieve rapid adjustment of the relative height of the loosening shovel 21. Even if the spring 24 loses its elasticity after long-term use and cannot push the lower crossbeam 22 to move away from the upper crossbeam 11 after the limiting nut 25 is loosened, the improved version only requires rotating the rotary joint 29 to drive the end screw 23 and its connected lower crossbeam 22 to move.
