Description

Technical Field

[0001] The utility model relates to the technical field of tillers, in particular to a tiller for improving garden soil. Background Art

[0002] In landscaping, the use of soil should be based on the soil conditions required by the biological characteristics of garden plants. Garden plants should be planted in soil suitable for their growth. For the soil where garden plants have already grown, the soil fertility factors should be artificially adjusted and improved according to the needs of garden plants for soil regulation. Soil turning is one of the ways to improve it. Usually the soil turning process needs to be achieved by a tiller.

[0003] However, when using the existing tillers for garden soil improvement, the inclination angle of the handrails of the tillers is usually fixed, and the inclination angle cannot be flexibly adjusted according to the user's own situation, which makes the tillers more laborious to use and inconvenient for users to operate. In addition, when the existing tillers are used for deep tillage of the soil, the compacted soil turned out is usually only stirred by the tilling blades. However, since the compacted soil after partial stirring still does not reach the ideal volume, the tilling effect is poor, and the tilling action needs to be repeated, resulting in a time-consuming process of tilling. Utility Model Content

[0004] The utility model aims to provide a tiller for improving garden soil, so as to solve the problems raised in the above-mentioned background technology.

In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0022] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] like Figures 1 to 4 As shown, the tiller for garden soil improvement in this embodiment includes a bracket 1, both sides of the bottom end of the bracket 1 are fixedly connected with a collar 17, the inner wall of the collar 17 is fixedly connected with a hub 13, the outer wall of the hub 13 is movably sleeved with an outer wheel 12, the middle part of the hub 13 is rotatably connected with a rotating column 14, the middle part of the rotating column 14 is engaged with a tilling tooth plate 15, one side of the rotating column 14 is provided with a retaining plate 9, the inner side of the retaining plate 9 is provided with a spring 10, one end of the spring 10 is fixedly connected with a ball 11, the top of the bracket 1 is fixedly connected with a gripping rod 2, the middle part of the gripping rod 2 is provided with a sleeve 7, one side wall of the sleeve 7 is movably penetrated with a fastening bolt 8, the other side wall of the sleeve 7 is fixedly connected with a sleeve 3, the interior of the sleeve 3 is provided with a docking rod 4, and a telescopic rod lock buckle 6 is installed at the junction of the sleeve 3 and the docking rod 4.

[0024] Specifically, the bracket 1 and the grip rod 2 form a "冂-shaped" structure, which serves as the armrest of this rotary tiller. The collar 17 plays a role in fixing the wheel hub 13, enabling the wheel hub 13 to be connected and fixed to the bottom end of the bracket 1, so that the bracket 1 can smoothly adjust the tilt angle. The inner diameter of the outer wheel 12 is adapted to the outer diameter of the wheel hub 13, enabling the outer wheel 12 to rotate along the outer wall of the wheel hub 13, so that the wheel hub 13 can move forward along the ground through the outer wheel 12, thereby realizing the movement of the rotary tiller on the soil surface. Both ends of the rotating column 14 are respectively connected to the two wheel hubs 13 through rotating parts, enabling the rotating column 14 to maintain its connection with the wheel hub 13 during rotation. The inner wall of the soil retaining plate 9 is arc-shaped, which can adapt to the circular path formed by the rotation of the soil turning tooth plate 15, enabling the turned soil to smoothly fly towards the baffle and collide with the ball 11 inside the baffle. The ball 11 is a solid structure, which can drive the deformation of the spring 10 and be continuously shaken by the acting force generated by the deformation of the spring 10, thereby realizing the collision and fragmentation of the turned compacted soil blocks, thus enhancing the soil turning effect of the rotary tiller. The surface of the grip rod 2 is treated with frosting, which is anti-slip, wear-resistant and not easy to slip off. The inner diameter of the sleeve 7 is adapted to the outer diameter of the grip rod 2, enabling the sleeve 7 to smoothly rotate along the outer wall of the grip rod 2, thereby realizing the change of the angle between the sleeve 3 and the grip rod 2, so that the tilt angle of the bracket 1 can be flexibly adjusted.

[0025] Further, the docking rod 4 is movably connected to the sleeve 3 through the telescopic rod lock 6. An auxiliary wheel 5 is installed at the bottom end of the docking rod 4. The auxiliary wheel 5 can prevent a large frictional resistance from being generated when the bottom end of the docking rod 4 contacts the soil surface, thus facilitating the operation by the user.

[0026] Further, a rubber pad is fixedly connected to the bottom end of the fastening bolt 8. The grip rod 2 is movably connected to the rubber pad. The sleeve 7 is movably sleeved on the grip rod 2 through the fastening bolt 8. The rubber pad is made of silicone and has a rough surface, enabling the end of the fastening bolt 8 to closely adhere to the outer surface of the grip rod 2, thereby realizing the temporary locking and fixing of the sleeve 7.

[0027] Further, the soil retaining plate 9 is fixedly connected to the bracket 1. The soil retaining plate 9 is movably connected to the soil turning tooth plate 15 through the bracket 1, enabling the soil retaining plate 9 to be adjusted to a position corresponding to the soil turning tooth plate 15 along with the adjustment of the bracket 1, realizing the soil retaining function of the soil retaining plate 9.

[0028] Further, one end of the spring 10 away from the ball 11 is fixedly connected to the soil retaining plate 9. The ball 11 is movably connected to the soil turning tooth plate 15 through the spring 10. The ball 11 can shake on the inner wall of the soil retaining plate 9 along with the deformation of the spring 10, thereby realizing the knocking of the ball 11 on the turned compacted soil blocks.

[0029] Furthermore, a drive motor 16 is fixedly installed in the middle of one of the wheel hubs 13, and the output end of the drive motor 16 is engaged and connected with the rotating column 14. After the drive motor 16 is connected to an external power supply, it drives the rotating column 14 to rotate along the wheel hub 13, thereby realizing the rotation of the rotating column 14 in the middle of the wheel hub 13.

[0030] Furthermore, the rotating column 14 is rotatably connected to the wheel hub 13 via a driving motor 16. When the rotating column 14 is driven to rotate by the driving motor 16, the soil turning tooth plates 15 on the rotating column 14 turn the soil, so that the deep soil can be turned out.

[0031] The method of using the present embodiment is as follows: when using the tiller for garden soil improvement, it is necessary to first connect the tiller to an external power source, and then according to one's own situation, the sleeve 7 can be rotated along the gripping rod 2, so that the sleeve 3 and the docking rod 4 at the bottom end of the sleeve 3 are rotated to be not in the same straight line with the gripping rod 2, and then the docking rod 4 is pulled out of the sleeve 3 to extend the length of the sleeve 3, and when the auxiliary wheel 5 at the bottom end of the docking rod 4 contacts the soil ground, the telescopic rod lock 6 is locked, and the fastening bolt 8 is tightened at the same time, at this time, the telescopic rod structure composed of the sleeve 3 and the docking rod 4 will form a stable triangular structure with the bracket 1 and the soil ground, so that the user can push the handle 2 while holding it. When the tiller is moving, it is more labor-saving. After pushing the handle 2, the outer wheel 12 outside the wheel hub 13 will rotate in contact with the soil ground, so that the wheel hub 13 moves along the soil ground, and at the same time, the driving motor 16 will drive the rotating column 14 to rotate, and drive the tilling tooth plate 15 on the rotating column 14 to till along the soil surface, so that the deep soil is turned out, and then the turned out compacted soil will fly to the baffle and collide with the ball 11 on the inner wall of the baffle, so that the ball 11 drives the spring 10 to deform, so that the ball 11 continues to shake under the action of the deformation of the spring 10, and the compacted soil flying to the retaining plate 9 is crushed for the second time, so that the turned out soil can be crushed to an ideal state.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein with equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
