Detailed Implementation

[0036] 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.

[0037] Those skilled in the art will understand that although some embodiments herein include certain features included in other embodiments but not others, combinations of features from different embodiments are intended to be within the scope of this invention and form different embodiments. For example, in the claims, any of the claimed embodiments can be used in any combination.

[0038] The following is a reference to the appendix. Figure 1 To be continued Figure 14 This utility model describes a soil conditioner that can be used on lawns, seedbeds, paddy fields, and other types of land. When used on lawns, it can break up the soil and aerate it; when used on seedbeds and paddy fields, it can refine the soil and remove weeds.

[0039] Currently, land maintenance mainly relies on single-function equipment, such as lawnmowers, aeration aerators, and soil shredders. While these devices can meet some maintenance needs, they have the following limitations:

[0040] Limited functionality: Each device can only perform a specific task, such as a lawnmower that is only used for mowing and a soil aerator that is only used for soil aeration, which cannot meet the comprehensive maintenance needs.

[0041] Inefficiency: Rotating multiple devices increases operational complexity and time costs, reducing maintenance efficiency.

[0042] High costs: Purchasing and maintaining multiple types of equipment increases the financial burden, especially for small and medium-sized land management units.

[0043] Therefore, this soil maintenance device includes a handheld rod 1, a connecting component 2 connected to the rod 1, and a soil maintenance component 3 connected to the rod 1 via the connecting component 2. The soil maintenance component 3 can rotate relative to the connecting component 2 to break up soil, aerate, and remove weeds. Specifically, the soil maintenance component 3 includes a soil maintenance roller and multiple soil maintenance toothed rings 32. The soil maintenance roller and the soil maintenance toothed rings 32 are detachably connected. The soil maintenance toothed rings 32 are arranged in a first direction with the soil maintenance roller as the axis. When the soil maintenance component 3 rotates to maintain the soil, the soil maintenance toothed rings 32 are always inserted into the soil.

[0044] Existing soil breakers have parallel rows of breaking teeth, resulting in mostly large pieces of soil being broken up during use, and the breaking effect is poor. This curing device, however, features multiple curing tooth rings 32 arranged in a first direction with the curing roller as the axis. (See reference...) Figure 2 This arrangement ensures that each angle of the curing roller's arc-shaped profile has a curing tooth ring 32, resulting in better soil breaking effect when the curing device is used.

[0045] The existing soil shredder has parallel rows of shredding teeth. As a result, when the teeth are inserted into the soil, the roller 31 comes into contact with the soil, causing bumps and uneven rolling. However, this curing device has multiple curing tooth rings 32 arranged in a first direction with the curing roller as the axis. This ensures that when the curing device is in use, there are always curing tooth rings 32 inserted into the soil, resulting in more balanced rolling.

[0046] Existing weed cutters have parallel rows of weeding teeth, which means they can only remove weeds in the axial direction between the teeth, resulting in poor weed removal. However, this maintenance device has multiple maintenance tooth rings 32 arranged in a first direction with the maintenance roller as the axis, so that the maintenance tooth rings 32 can remove weeds in the soil in both the radial and axial directions when the device is in use.

[0047] See Figure 3 The first direction is a direction line with an inclined angle that rotates along the axis of the curing roller, so that the curing toothed rings 32 are staggered, thus ensuring that there are curing toothed rings 32 at every angle. (See reference...) Figure 2 Preferably, the axial spacing between each maintenance toothed ring 32 is the same, and the angle of rotation of each maintenance toothed ring 32 along the first direction is the same.

[0048] The maintenance tooth ring 32 includes a ring body 321 and a plurality of maintenance teeth 322. The ring body 321 is fixedly connected to the plurality of maintenance teeth 322. The plurality of maintenance teeth 322 are arranged in an array along the arc-shaped contour of the ring body 321. Preferably, the angle of the plurality of maintenance teeth 322 arranged along the arc-shaped contour of the ring body 321 is the same, and each row of maintenance teeth 322 is arranged in a first direction.

[0049] Preferably, the angle between the head maintenance tooth 322 of each row of maintenance teeth 322 and the tail maintenance tooth 322 of the adjacent row of maintenance teeth 322 is the same as the angle of rotation of each row of maintenance teeth 322 in the first direction, and the angle between the tail maintenance tooth 322 of each row of maintenance teeth 322 and the head maintenance tooth 322 of the adjacent row of maintenance teeth 322 is the same as the angle of rotation of each row of maintenance teeth 322 in the first direction.

[0050] Regarding the rotation method of the curing roller, the curing roller includes a roller body 31 and a rotating shaft 33. The roller body 31 is connected to the curing toothed ring 32 and the rotating shaft 33. The roller body 31 drives the curing toothed ring 32 to rotate relative to the connecting assembly 2 with the rotating shaft 33 as the center.

[0051] The roller body 31 includes a first roller 311, a second roller 312, and a cover plate 313. Multiple first rollers 311 are connected together. The first rollers 311 at both ends are respectively connected to the second rollers 312. The second rollers 312 are connected to the cover plate 313, and the cover plate 313 is fixedly connected to the rotating shaft 33. Specifically, multiple first rollers 311 are connected to each other, and the two first rollers 311 at both ends are respectively connected to the second rollers 312. The second rollers 312 have… There are two rollers, which are connected to the first roller 311 located at both ends. The end of the second roller 312 away from the first roller 311 is connected to the cover plate 313. The cover plate 313 is fixedly connected to the rotating shaft 33. A first slot 314 is provided between adjacent first rollers 311 and between adjacent first rollers 311 and second rollers 312. The first slot 314 engages with the maintenance tooth 322, so that when the rotating shaft 33 rotates, the first roller 311 drives the maintenance tooth 322 to rotate.

[0052] In most existing soil shredders or weeders, the teeth are directly welded to the roller body 31. This connection method is not secure and teeth are prone to falling off during use. Furthermore, it is impossible to replace the teeth when they are damaged. In contrast, this curing device has a first groove 314 between adjacent first rollers 311 and between adjacent first rollers 311 and second rollers 312. The first groove 314 engages with the curing teeth 322, making the connection between the curing teeth 322 and the roller body 31 secure and preventing teeth from falling off. In addition, if the curing teeth 322 are damaged, the curing tooth ring 32 can be directly replaced.

[0053] The first roller 311 has a first connecting groove 3111 and a second connecting groove 3112 at both ends. The second connecting groove 3112 and the first connecting groove 3111 are arranged in an array along a first direction. When adjacent first rollers 311 are connected, the adjacent first connecting groove 3111 and the second connecting groove 3112 combine to form a first locking groove 314. The first roller 311 has a second locking groove 3114 and a second locking block 3113 at both ends. When adjacent first rollers 311 are connected, the second locking groove 3114 and the second locking block 3113 engage. Specifically, the first connecting groove of each first roller 31 is... The groove 3111 and the second connecting groove 3112 are both staggered, and the first connecting groove 3111 and the second connecting groove 3112 are staggered with the first direction. When adjacent first roller pieces 311 are connected, the adjacent first connecting groove 3111 and the second connecting groove 3112 are combined to form the first slot 314. At this time, the adjacent first connecting groove 3111 and the second connecting groove 3112 completely overlap and are combined to form the first slot 314. When assembling the first roller body 31, the first roller body 31 is connected to the first roller body 31 through the second slot 3114 and the second locking block 3113, which improves the assembly efficiency.

[0054] The second roller 312 has a third connecting groove 3121 at one end near the first roller 311. When the second roller 31 is connected to the first roller 31, the adjacent third connecting groove 3121 combines with the first connecting groove 3111 or the second connecting groove 3112 to form a first locking groove 314. The two second rollers 312 are respectively provided with a third locking block 3122 and a third locking groove. When the adjacent first roller 311 and second roller 312 are connected, the third locking block 3122 locks into the second locking groove 3114. Then, the third slot engages with the second slot block 3113. Specifically, when the second roller body 31 is connected to the first roller body 31, the adjacent third connecting slot 3121 and the first connecting slot 3111 combine to form the first slot 314, and the other adjacent third connecting slot 3121 and the second connecting slot 3112 combine to form the first slot 314. When assembling the first roller body 31, the first roller body 31 and the second roller body 31 are connected through the third slot and the second slot block 3113, which improves the assembly efficiency.

[0055] The second roller 312 is provided with a fourth slot 3131 or a fourth block 3123, and the cover plate 313 is provided with a fourth block 3123 or a fourth slot 3131. When the second roller 312 is connected to the cover plate 313, the fourth slot 3131 engages with the fourth block 3123. Specifically, when the second roller 312 is provided with a fourth slot 3131, the cover plate 313 is provided with a fourth block 3123, and when the second roller 312 is provided with a fourth block 3123, the cover plate 313 is provided with a fourth slot 3131. The second roller 31 is connected to the cover plate 313 through the fourth slot 3131 and the fourth block 3123, which improves the assembly efficiency.

[0056] The rotating shaft 33 includes a shaft body 331 and a bolt 332. The shaft body 331 is connected to the head of the bolt 332. The cover plate 313 and the connecting assembly 2 are sleeved on the rod body 1 of the bolt 332. A nut 333 is screwed onto the rod body 1 of the bolt 332, and the cover plate 313 and the connecting assembly 2 are fixed by the nut 333.

[0057] Specifically, a first washer 334 is fitted on the shank 1 of bolt 332, and a first gap 337 is provided between the first washer 334 and the head of bolt 332. The cover plate 313 is located within the first gap 337. A second washer 335 is fitted on the shank 1 of bolt 332, and a second gap 338 is provided between the second washer 335 and the first washer 334. The connecting component 2 is located within the second gap 338. The nut 333 is located at the end of the second washer 335 away from the first washer 334. By tightening the nut 333, the assembled roller 31 and the connecting component 2 are fixed. The nut 333 and the bolt facilitate assembly and disassembly. Preferably, a collar 336 is provided inside the first washer 334 and the second washer 335. The collar 336 is fitted onto the shank 1 of bolt 332, and both the first washer 334 and the second washer 335 are fitted onto the collar 336.

[0058] The connecting component 2 has a first through hole 23, and the rod body 1 has a second through hole. After the connecting component 2 contacts the rod body 1 and the first through hole 23 coincides with the second through hole, the fastening component passes through the first through hole 23 and the second through hole to fix the connecting component 2 and the rod body 1. Specifically, the fastening component can be a nut 333 and a bolt 332, which fix the connecting component 2 and the rod body 1. In other embodiments of this utility model, the fastening component can also be a fixing pin, etc., as long as it can fix the connecting component 2 and the rod body 1.

[0059] The connecting component 2 includes two connecting plates 21, each with a first through hole 23 and an integrally formed reinforcing rib 22. During use, the connecting plates 21 are easily affected by stress and deform. The reinforcing rib 22 improves the strength of the connecting plates 21 and prevents deformation.

[0060] This curing device consists of multiple parts, all of which are detachable. During transportation or packaging, the rods 1 are packed together, the connecting components 2 are packed together, the cover plates 313 are packed together, the curing toothed rings 32 are packed together, the first roller 31 is packed together, and the rotating shaft 33 is packed together. This reduces the transportation area, facilitates transportation, and eliminates safety hazards.
