AI Technical Summary
Existing lawn rollers are assembled and welded as a whole. When a part of the structure wears out, the entire roller needs to be replaced, which shortens the lifespan and is not conducive to subsequent use.
The design employs a split-structure mesh unit and end cap, which are connected by nuts and bolts to allow for the disassembly and replacement of partial components, forming a cage-like structure for use.
This allows for the replacement of only a single component when there is localized wear, extending the service life of the lawn roller and improving its practicality.

Abstract
Description
Technical Field
[0001] This utility model belongs to the field of lawn rollers, and specifically relates to an assembled lawn roller that is easy to transport. Background Technology
[0002] Currently, landscaping lawns are artificial grasslands made by densely planting and mowing perennial, low-growing herbaceous plants. Large lawns appeared in English landscape gardens in the mid-18th century. Lawns also appeared in modern Chinese gardens, with main varieties including Kentucky bluegrass, tall fescue, evergreen turf, cool-season turf, and mixed-species lawns. Lawns require appropriate lawn rollers for trampling and fertilization.
[0003] However, existing lawn rollers are mostly assembled and welded as a whole. When excessive wear occurs in a local structure, the entire lawn roller needs to be replaced, which greatly reduces the lifespan of the lawn roller and is not conducive to subsequent use.
[0004] Therefore, in view of the shortcomings of the above-mentioned solutions in actual production and implementation, modifications and improvements have been made. At the same time, in the spirit and concept of seeking excellence, and with the assistance of professional knowledge and experience, and after much ingenuity and experimentation, this utility model was created. It provides a convenient transportable assembled lawn roller to solve the problem that existing lawn rollers, which are mostly integrally assembled and welded, require the replacement of the entire lawn roller when excessive wear occurs in some parts of the structure, which greatly reduces the lifespan of the lawn roller and is not conducive to subsequent use. Utility Model Content
[0005] This utility model proposes an assembled lawn roller that is easy to transport, solving the problem that existing lawn rollers, which are mostly integrally assembled and welded, require the entire lawn roller to be replaced when excessive wear occurs in some parts, thus greatly reducing the lifespan of the lawn roller and hindering its subsequent use.
[0006] The technical solution of this utility model is implemented as follows: the convenient transportable assembled lawn roller includes: end caps, of which there are two end caps arranged opposite each other. The end caps have a disc-shaped structure, and a rotating shaft is installed inside the end cap. Locks are fixedly connected to the outer sides of both end caps. The end caps and the rotating shaft together form a connecting structure, and nuts are riveted in a circular array inside the end caps.
[0007] In a preferred embodiment, a fixing bolt is screwed into the inside of the nut, and a mesh unit A is installed through the fixing bolt.
[0008] In a preferred embodiment, the mesh unit A is provided in three locations, and the three mesh units A are arranged in a ring array and installed on the inner side of the two end caps.
[0009] In a preferred embodiment, the mesh unit A has an arc-shaped structure, and an inner buckle plate is fixedly connected to the inner wall of each mesh unit A. The inner buckle plate and the mesh unit A together form a connection structure.
[0010] In a preferred embodiment, the mesh unit A has an internal mounting hole that matches the fixing bolt installed in the nut.
[0011] In a preferred embodiment, a hinge is fixedly connected to the top of the upper mesh unit A. There are two hinges, which are fixedly connected in a straight line array to the top of the outer peripheral surface of the mesh unit A. A mesh unit B is fixedly connected to the side of the two hinges away from the mesh unit A. A hook is fixedly connected to the outer side of the mesh unit B. There are two hooks, which are fixedly connected to the left and right sides of the mesh unit B in opposite directions and match the lock fixedly connected to the outer surface of the end cap.
[0012] After using the above technical solution, the beneficial effects of this utility model are:
[0013] 1. In this utility model, a hinge is fixedly connected to the outside of the mesh unit A. A mesh unit B is fixedly connected to the side of the hinge away from the mesh unit A. When the mesh unit B and the mesh unit A are used, they can be assembled to form a cage-like structure, thereby achieving a more practical purpose.
[0014] 2. In this utility model, by setting a split structure mesh unit A and end cap, if a single mesh unit A is excessively worn and affects its use, the fixing bolt can be removed from the inside of the mesh unit A and the nut, and the single mesh unit A can be replaced, thereby achieving a more practical purpose.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] like Figures 1-6 As shown, the convenient transportable assembled lawn roller includes: end caps 1, two end caps 1 are provided, the two end caps 1 are arranged opposite each other, the end caps 1 are disc-shaped structures, the inside of the end caps 1 are installed with a rotating shaft 101, and the outside of the two end caps 1 are fixedly connected with locks 102. The end caps 1 and the rotating shafts 101 together form a connection structure, and the inside of the end caps 1 are riveted with nuts 103 in a ring array. The side of the two hinges 3 away from the mesh unit A2 is fixedly connected to the mesh unit B301. The outside of the mesh unit B301 is fixedly connected with hooks 302. There are two hooks 302, the two hooks 302 are fixedly connected opposite each other to the left and right sides of the mesh unit B301, and match the locks 102 fixedly connected to the outside of the end caps 1.
[0025] The nut 103 is screwed with a fixing bolt 104 inside, and a mesh unit A2 is installed through the fixing bolt 104. There are three mesh units A2 in total, and the three mesh units A2 are installed in a ring array on the inner side of the two end caps 1.
[0026] Among them, the mesh unit A2 has an arc-shaped structure, and an inner buckle plate 201 is fixedly connected to the inner wall of the mesh unit A2. The inner buckle plate 201 and the mesh unit A2 together form a connection structure. The mesh unit A2 has an installation hole 202 inside, which matches the fixing bolt 104 installed in the nut 103. The top of the mesh unit A2 located on the upper side is fixedly connected to a hinge 3. There are two hinges 3 in total, and the two hinges 3 are fixedly connected to the top of the outer peripheral surface of the mesh unit A2 in a straight line array.
[0027] When using the lawn roller, during assembly, the inner nut pieces 103 of both end caps 1 are riveted together, and the three mesh units A2 and the mesh unit B301 that is rotatably connected to the outside of the mesh unit A2 via the hinge 3 are sequentially fitted onto the outer positions of the two end caps 1. Then, the fixing bolts 104 are sequentially passed through the mounting holes 202 opened in the mesh unit A2 and the mesh unit B301 from the outside to the inside, and connected and assembled with the nut pieces 103 provided in the end caps 1.
[0028] Furthermore, after assembly, the mesh unit B301 can be limited by two fixing methods: fixing bolt 104 and locking device 102. If it is necessary to limit it separately by locking device 102, the mesh unit B301 can be folded open, and the seeds and fertilizers to be cultivated can be put into the mesh unit A2 at the same time. Then, the corresponding bracket is used to connect with the rotating shaft 101 set on the outside of the end cover 1, and the whole device is rolled and pushed to achieve the purpose of sowing or fertilizing.
