Description

Technical Field

[0001] This utility model belongs to the technical field of garden tools, and in particular relates to a soil tiller. Background Technology

[0002] If soil is not loosened for a long time, it will easily clump together, which reduces the aeration of plant roots, as if sealing the roots. Loosening the soil increases the gaps between soil particles, allowing air to enter more easily, increasing root cell respiration. Enhanced respiration strengthens transpiration, promotes the exchange of mineral elements between root hairs and the soil, and thus promotes the absorption of mineral elements by the roots. Therefore, regular soil loosening is necessary, which is why soil loosening tools are used.

[0003] In existing garden tillers, the loosening claws and connectors at the bottom are not detachable. However, the loosening claws are prone to severe deformation after prolonged use, which affects the loosening effect. Once the loosening claws are deformed, the entire tiller needs to be scrapped, thus shortening the product's lifespan. Therefore, improvements are needed. Utility Model Content

[0004] The purpose of this utility model is to provide a soil tiller that solves the problem that the soil tiller's lower soil tiller uses a non-removable connection between the soil tiller claw and the connecting part. As a result, the soil tiller claw is prone to severe deformation after long-term use, which affects the soil tiller effect. Once the soil tiller claw is deformed, the entire soil tiller needs to be scrapped, thus shortening the product's service life.

Detailed Implementation

[0026] 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 in conjunction with the embodiments of this utility model. 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.

[0027] Example 1

[0028] Please see Figure 1-8As shown, this embodiment discloses a soil loosening device, including a soil loosening component 1 and a connecting rod 2. The soil loosening component 1 includes a connecting seat 101 and a plurality of spirally shaped soil loosening claws 102 disposed on the connecting seat 101. The connecting seat 101 includes a connecting upper cover 1011 and a connecting lower cover 1012 that cooperate with each other. A connecting tube 1013 that can be inserted into the lower end of the connecting rod 2 is disposed above the connecting upper cover 1011. A mounting through hole 3 is provided on both sides of the connecting tube 1013. 3. Symmetrical arrangement: The corresponding position of the connecting rod 2 is provided with a second mounting through hole 4 aligned with the first mounting through hole 3. A long screw 5 is inserted between the first mounting through hole 3 and the second mounting through hole 4. The long screw 5 passes through the first mounting through holes 3 on both sides and is threadedly connected to a locking nut 6. One end of the loosening claw 102 is inserted into the cavity formed by the upper connecting cover 1011 and the lower connecting cover 1012. The upper connecting cover 1011 and the lower connecting cover 1012 are locked together by a locking screw 18 to limit and fix the loosening claw 102.

[0029] Preferably, for ease of positioning, each loosening claw 102 is provided with a T-shaped limiting post 7 at one end. The lower part of the connecting upper cover 1011 is provided with one or more locking grooves 8, and the upper part of the connecting lower cover 1012 is provided with a locking groove 9 corresponding to the locking groove 8. The corresponding locking grooves 8 and the locking grooves overlap to form a limiting hole for fixing the T-shaped limiting post 7. Through the above structural setting, the upper end of each loosening claw 102 can be limited, avoiding the loosening claw 102 from detaching after fixing or causing the loosening claw 102 to be unreliably fixed.

[0030] Preferably, for ease of positioning, the lower side of the connecting upper cover 1011 is provided with one or more limiting notches 11, and the upper part of the connecting lower cover 1012 is provided with one or more limiting trapezoidal protrusions 12. Each limiting trapezoidal protrusion 12 is inserted into a limiting notch 11. In this embodiment, when the connecting upper cover 1011 and the connecting lower cover 1012 are closed, the limiting notch 11 and the limiting trapezoidal protrusion 12 are aligned and inserted to facilitate the fixing and positioning of the two. Then, the connecting upper cover 1011 and the connecting lower cover 1012 are connected by screwing through the through hole in the center of the connecting lower cover 1012 and screwing it into the connecting upper cover 1011. This also facilitates disassembly later.

[0031] Preferably, for easy adjustment of the overall length, the connecting rod 2 includes an upper connecting rod body 201 and a lower connecting rod body 202. The lower end of the lower connecting rod body 202 is used to insert the connecting pipe 1013, and the upper end of the lower connecting rod body 202 is inserted into the lower end of the upper connecting rod body 201. A mounting through hole 33 is provided on both sides of the upper end of the lower connecting rod body 202, and the two mounting through holes 33 are symmetrically arranged. A corresponding position on the lower end of the upper connecting rod body 201 is provided with a mounting through hole 33. The upper connecting rod 201 has three aligned mounting through holes 14, and two mounting through holes 14 are provided on each side of the lower end of the upper connecting rod 201. A long screw 15 is inserted between the mounting through hole 3 13 and the mounting through hole 14. The long screw 15 passes through the mounting through holes 3 13 on both sides and is threaded to a locking nut 16. A handle 17 is inserted into the upper end of the upper connecting rod 201. Through the above structure, the upper connecting rod 201 can be adjusted to be inserted into the lower connecting rod according to the length requirements. To fix the upper connecting rod 201 and the lower connecting rod 202 to the depth 202, simply align the two mounting through holes 14 and 13 at the same height, then pass the long screw 15 from left to right through the left mounting through hole 13, the left mounting through hole 14, the right mounting through hole 14, and the right mounting through hole 13, and finally lock it with the locking nut 16. Similarly, the installation method for the lower connecting rod 202 and the connecting pipe 1013 is the same. Insert the connector 1013 into the lower connecting rod 202, ensuring that the first mounting through hole 3 and the second mounting through hole 4 are aligned. Then, let the long screw 5 pass through the left mounting through hole 3, the left mounting through hole 4, the right mounting through hole 4, and the right mounting through hole 3 from left to right, and lock it with the locking nut 6 to fix the connector 1013 to the lower connecting rod 202. The installation method of the handles above the upper connecting rod 201 and below the handle 17 along the lifting rod is the same, so it will not be described in detail.

[0032] Preferably, the end of the loosening claw 102 away from the connecting seat 101 is formed into a pointed part 102, so that the loosening claw 102 can be inserted into the soil. The diameter of the longitudinal rod of the T-shaped limiting post 7 is larger than the maximum diameter of the loosening claw 102, so as to limit one end of the loosening claw 102 during installation and prevent the loosening claw 102 from coming out of the limiting hole after the connecting upper cover 1011 and connecting lower cover 1012 are locked by the locking screw 18.

[0033] Preferably, for ease of insertion, the lower connecting rod 202 is provided with a support groove 2021 at both the top and bottom. By providing the support groove 202, the lower connecting rod 202 can be appropriately supported when the corresponding connecting pipe 1013 or the upper connecting rod 201 is inserted, further facilitating insertion.

[0034] As a preferred option, to prevent slippage when gripping, the handle 17 is provided with anti-slip sleeves 10 at both ends. By providing anti-slip sleeves 10 at both ends of the handle 17, it is convenient to grip and prevent slippage.

[0035] The soil loosening component 1 in this structure includes a connecting seat 101 and several spirally arranged soil loosening claws 102 disposed on the connecting seat 101. The connecting seat 101 includes a separable upper connecting cover 1011 and a lower connecting cover 1012. The soil loosening claws 102 are disposed in the cavity where the upper connecting cover 1011 and the lower connecting cover 1012 mate. The upper connecting cover 1011 and the lower connecting cover 1012 are locked with locking screws 18 to limit and fix the soil loosening claws 102. Later, when one of them is used for a long time, if it is found that one of the loosening claws is not properly positioned, the loosening claws will be fixed in place. When the root loosening claw 102 is severely deformed or broken, simply loosen the locking screw 18 to separate the connecting upper cover 1011 and the connecting lower cover 1012. The corresponding loosening claw 102 can then be removed for replacement, further improving the product's service life. At the same time, the connecting upper cover 1011 is equipped with a connecting tube 1013, which can be inserted into the connecting rod 2 and locked with the long screw 5 and the locking nut 6. This improves the connection strength between the connecting upper cover 1011 and the connecting rod 2 and also facilitates later disassembly.

[0036] The above are merely preferred embodiments of the present utility model and do not limit the present utility model. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall fall within the protection scope of the present utility model.
