[0019] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0020] Those skilled in the art can understand that although some embodiments herein include certain features included in other embodiments rather than other features, the combination of features of different embodiments means that it is within the scope of the present invention and forms different embodiments. For example, in the claims, any one of the claimed embodiments can be used in any combination.

[0021] The following refers to the attached Figure 1 to the attached Figure 14 Describe a cultivator of the present invention. This cultivator can be used for lands such as lawns, seedling fields, and paddy fields. When used on lawns, it can break up the soil and aerate the lawn; when used on seedling fields and paddy fields, etc., it can level the land and at the same time remove weeds.

[0022] Currently, land cultivation mainly relies on single-function equipment, such as lawn mowers, aeration hole punchers, and soil breakers, etc. Although these equipment can meet some cultivation needs, they have the following limitations: Single function: Each piece of equipment can only complete specific tasks. For example, a lawn mower is only used for trimming, and a hole puncher is only used for soil aeration, unable to meet the comprehensive cultivation needs.

[0023] Low efficiency: The rotation use of multiple equipment increases the operation complexity and time cost, reducing the cultivation efficiency.

[0024] High cost: Purchasing and maintaining multiple equipment increases the economic burden, especially for small and medium-sized land management units.

[0025] Therefore, this cultivator includes a rod body 1 for holding by hand. A connecting component 2 is connected to the rod body 1. The rod body 1 is connected with a cultivation component 3 through the connecting component 2. The cultivation component 3 can rotate relative to the connecting component 2 to break up the soil, aerate the soil and remove weeds from the land. Specifically, the cultivation component 3 includes a cultivation roller and a plurality of cultivation tooth rings 32. The cultivation roller and the cultivation tooth rings 32 are detachably connected. The cultivation tooth rings 32 are arrayed along the first direction with the cultivation roller as the axis. When the cultivation component 3 rotates to cultivate the land, the cultivation tooth rings 32 are always inserted into the land.

[0026] The soil-breaking teeth on the existing soil breaker are parallel in each row. Therefore, when the existing soil breaker is used, most of the broken soil is in large chunks and the soil-breaking effect is poor. However, in this cultivator, since a plurality of cultivation tooth rings 32 are arrayed along the first direction with the cultivation roller as the axis, referring to Figure 2 , so that on the cross-section of the arc-shaped contour of the cultivation roller, there are cultivation tooth rings 32 at each angle. Therefore, when this cultivator is used, the cultivation tooth rings 32 have a better soil-breaking effect through this arrangement.

[0027] In the existing soil crusher, the soil crushing teeth thereon are parallel in each row. Therefore, during use, after the teeth are inserted into the soil, the roller body 31 contacts the soil, causing bumps and unbalanced rolling. However, in this maintainer, since multiple maintenance tooth rings 32 are arrayed along the first direction with the maintenance roller as the axis, when this maintainer is in use, there is always a maintenance tooth ring 32 inserted into the soil, so the rolling is more balanced.

[0028] In the existing weeder, the weeding teeth thereon are parallel in each row. Therefore, during use, only the weeds in the axial direction between the weeding teeth can be removed, and the weeding effect is poor. However, in this maintainer, since multiple maintenance tooth rings 32 are arrayed along the first direction with the maintenance roller as the axis, when this maintainer is in use, the maintenance tooth rings 32 can remove the weeds in the soil both radially and axially.

[0029] Refer to Figure 3 , the first direction is a direction line with an inclination angle and formed by rotating around the maintenance roller as the axis, so that the maintenance tooth rings 32 are staggered, and thus there is a maintenance tooth ring 32 at each angle. Refer to Figure 2 , preferably, the axial intervals between each maintenance tooth ring 32 are the same, and the angles of rotation of each maintenance tooth ring 32 along the first direction are the same.

[0030] The maintenance tooth ring 32 includes a ring body 321 and multiple maintenance teeth 322. The ring body 321 is fixedly connected to the multiple maintenance teeth 322, and the multiple maintenance teeth 322 are arrayed along the arc contour of the ring body 321. Preferably, the angles at which the multiple maintenance teeth 322 are arrayed along the arc contour of the ring body 321 are the same, and each row of maintenance teeth 322 is arrayed in the first direction.

[0031] Preferably, the angle between the head maintenance teeth 322 of each row of maintenance teeth 322 and the tail maintenance teeth 322 of the adjacent row of maintenance teeth 322 is the same as the angle of rotation of each row of maintenance teeth 322 along the first direction, and the angle between the tail maintenance teeth 322 of each row of maintenance teeth 322 and the head maintenance teeth 322 of the adjacent row of maintenance teeth 322 is the same as the angle of rotation of each row of maintenance teeth 322 along the first direction.

[0032] Regarding the rotation mode of the maintenance roller, the maintenance roller includes a roller body 31 and a rotating shaft 33. The roller body 31 is connected to the maintenance tooth ring 32, and the roller body 31 is connected to the rotating shaft 33. The roller body 31 drives the maintenance tooth ring 32 to rotate relative to the connecting component 2 with the rotating shaft 33 as the center.

[0033] The roller body 31 includes a first roller member 311, a second roller member 312, and a cover plate 313. A plurality of first roller members 311 are connected to each other. The first roller members 311 at both ends are respectively connected to the second roller members 312. The second roller members 312 are connected to the cover plate 313. The cover plate 313 is fixedly connected to the rotating shaft 33. Specifically, a plurality of first roller members 311 are connected to each other. The two first roller members 311 at both ends are respectively connected to the second roller members 312. The specific number of the second roller members 312 is two, which are respectively connected to the first roller members 311 at both ends. One end of the second roller member 312 away from the first roller member 311 is connected to the cover plate 313. The cover plate 313 is fixedly connected to the rotating shaft 33. First card slots 314 are provided between adjacent first roller members 311 and between adjacent first roller members 311 and second roller members 312. The first card slots 314 are clamped with the maintenance teeth 322. Thus, when the rotating shaft 33 rotates, the first roller member 311 drives the maintenance teeth 322 to rotate.

[0034] For the tooth bodies on the existing soil crushers or weeding machines, most of them directly weld the tooth bodies on the roller body 31. This connection method is not firm, and the teeth are likely to fall off during use. At the same time, when the tooth bodies are damaged, the tooth bodies cannot be replaced. However, in this maintenance device, first card slots 314 are provided between adjacent first roller members 311 and between adjacent first roller members 311 and second roller members 312. The first card slots 314 are clamped with the maintenance teeth 322, making the connection between the maintenance teeth 322 and the roller body 31 firm and not easy to lose teeth. At the same time, after the maintenance teeth 322 are damaged, the maintenance tooth ring 32 can be directly replaced.

[0035] First connection grooves 3111 and second connection grooves 3112 are respectively formed at both ends of the first roller member 311. The second connection grooves 3112 are arranged in an array along the first direction with the first connection grooves 3111. When adjacent first roller members 311 are connected, the adjacent first connection grooves 3111 and second connection grooves 3112 are combined into the first card slots 314. Second card slots 3114 and second clamping blocks 3113 are respectively provided at both ends of the first roller member 311. When adjacent first roller members 311 are connected, the second card slots 3114 are clamped with the second clamping blocks 3113. Specifically, the first connection grooves 3111 and second connection grooves 3112 of each first roller body 31 are staggered, and the first connection grooves 3111 and second connection grooves 3112 are staggered with the first direction. When adjacent first roller members 311 are connected, the adjacent first connection grooves 3111 and second connection grooves 3112 are combined into the first card slots 314. At this time, the adjacent first connection grooves 3111 and second connection grooves 3112 are completely overlapped and combined into the first card slots 314. When assembling the first roller body 31, the first roller body 31 is connected to the first roller body 31 through the second card slots 3114 and second clamping blocks 3113, improving the assembly efficiency.

[0036] One end of the second roller member 312 close to the first roller member 311 is provided with a third connection groove 3121. When the second roller body 31 is connected to the first roller body 31, the adjacent third connection groove 3121 and the first connection groove 3111 or the second connection groove 3112 are combined into a first clamping groove 314. Third clamping blocks 3122 and third clamping grooves are respectively provided on two second roller members 312. When the adjacent first roller member 311 and second roller member 312 are connected, the third clamping block 3122 is clamped with the second clamping groove 3114, and the third clamping groove is clamped with the second clamping block 3113. Specifically, when the second roller body 31 is connected to the first roller body 31, the adjacent third connection groove 3121 and the first connection groove 3111 are combined into a first clamping groove 314, and another adjacent third connection groove 3121 and the second connection groove 3112 are combined into a first clamping groove 314. When assembling the first roller body 31, the first roller body 31 and the second roller body 31 are connected through the third clamping groove and the second clamping block 3113, improving the assembly efficiency.

[0037] The second roller member 312 is provided with a fourth clamping groove 3131 or a fourth clamping block 3123, and the cover plate 313 is provided with a fourth clamping block 3123 or a fourth clamping groove 3131. When the second roller member 312 is connected to the cover plate 313, the fourth clamping groove 3131 is clamped with the fourth clamping block 3123. Specifically, when the second roller member 312 is provided with a fourth clamping groove 3131, the cover plate 313 is provided with a fourth clamping block 3123. When the second roller member 312 is provided with a fourth clamping block 3123, the cover plate 313 is provided with a fourth clamping groove 3131. The second roller body 31 and the cover plate 313 are connected through the fourth clamping groove 3131 and the fourth clamping block 3123, improving the assembly efficiency.
