Description

Technical Field

[0001] The present application relates to the technical field of landscaping, and in particular to a lawn rolling device. Background Art

[0002] Lawn rolling is an important part of lawn maintenance. Rolling can make the lawn soil more compact, which is conducive to the growth of lawn grass and keeps the lawn smooth and beautiful.

[0003] At present, the lawn rolling devices available on the market mainly include two categories: manual rolling equipment and mechanical rolling equipment. Mechanical rolling equipment is generally powered by power, with heavy equipment weight and good rolling effect, but there are also some problems. First, the weight adjustment of this equipment is relatively complicated, requiring professional operation, and the adjustment range is limited. Secondly, the weight of the mechanical rolling equipment is too heavy, and rolling the lawn may cause excessive compaction, which may not only affect the aesthetics of the lawn, but also inhibit the normal growth and recovery ability of the lawn. Over-rolled lawns may lose their original softness and elasticity, become hard and lack vitality. Manual rolling equipment is generally pushed by the operator, and the lawn is rolled by the weight of the equipment itself. This equipment has a simple structure and is easy to operate, but it has some shortcomings. First, due to the fixed weight of the equipment, it is difficult for the operator to adjust the weight of the rolling according to actual needs, which may result in unsatisfactory rolling effect. Secondly, the operating height of this equipment is generally fixed, and it cannot adapt to operators of different heights, making the operator prone to fatigue when used for a long time.

DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0026] Example:

[0027] See also Figure 1 , Figure 3 A lawn rolling device comprises a push rod 1 and an anti-skid sleeve 3 sleeved on the outer wall of the push rod 1.

[0028] The push rod 1 is the main operating part of the device. The push rod 1 is made of a light but strong material, such as aluminum alloy or carbon fiber. Its length can be adjusted according to the length and requirements of the roller 21 to adapt to rollers 21 of different lengths. The outer wall of the push rod 1 is covered with an anti-slip cover 3 to improve the stability and safety of holding.

[0029] The anti-skid sleeve 3 is made of soft rubber or silicone material and has good anti-skid performance. It is tightly sleeved on the outer wall of the push rod 1 to ensure that the operator can firmly hold the push rod when pushing the device to prevent sliding or slipping.

[0030] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 A lawn rolling device includes a rolling mechanism 2 welded at both ends of a push rod 1, the rolling mechanism 2 is composed of a rolling member 21, a hinge member 22, a telescopic member 23 and a limit member 24, wherein the rolling member 21 includes a rolling cylinder 211, two card slots 212, a filler 213, two card blocks 214 and two sealing gaskets 215; the hinge member 22 includes two grooves 221, a bearing 222, two threaded heads 223, two holes 224 and a locking nut 225; the telescopic member 23 includes two sleeve rods 231 and two telescopic rods 232; the limit member 24 includes two groups of adjusting nuts 241, two groups of adjusting screws 242 and a plurality of hole slots 243.

[0031] Among them, the design of the roller 21 is for rolling the lawn, and the rolling cylinder 211 is made of solid metal to ensure that it can withstand the pressure generated during the rolling process. The length and diameter of the rolling cylinder 211 are determined according to the expected rolling effect and the size of the lawn. At both ends of the rolling cylinder 211, we have opened two slots 212, which are used to fix the block 214, and the block 214 is tightly glued with the sealing pad 215 to ensure the sealing and fixation of the filler 213. The filler 213 can be sand, water or other weight media, which can be selected according to the type of lawn to be rolled and the soil conditions. The block 214 is connected to the inside of the slot 212 by bolts to ensure the stability of the structure. The sealing pad 215 ensures that the filler 213 will not leak out and keeps the weight of the rolling cylinder 211 stable. In this way, the operator can add or reduce the filler 213 inside the rolling cylinder 211 as needed, thereby adjusting the weight of the roller 21 to adapt to different lawn rolling needs. This design makes the lawn rolling device highly flexible and practical.

[0032] The hinge 22 is designed to ensure that the roller 21 can rotate smoothly while maintaining its stability during the rolling process. The groove 221 is located at the separated end of the block 214 and is used to embed the bearing 222. The selection of the bearing 222 depends on the load and rotation speed it can withstand, and reduces friction and improves efficiency. The thread head 223 is fixedly connected to the bearing 222 through the inner ring of the bearing 222, and its separated end passes through the hole 224 on the side wall of the telescopic member 23. These thread heads 223 are threadedly connected with the inner ring of the locking nut 225, so that the locking nut 225 can be fixed on the telescopic member 23, and the inner wall of the locking nut 225 fits with the outer side wall of the telescopic member 23 to ensure the stability of the structure. The design of the hinge 22 improves the flexibility and durability of the lawn rolling device, allowing operators to adjust and operate the equipment more easily, thereby improving the efficiency and effect of lawn rolling.

[0033] Among them, the design of the telescopic member 23 enhances the adaptability and humanization of the lawn rolling device, so that different users can use the device efficiently under different working conditions. Holes 224 are provided on the bottom side wall of the sleeve rod 231, which are convenient for the threaded head 223 to pass through. The design of the sleeve rod 231 makes it fit closely with the opposite ends of the rolling cylinder 211 and the locking nut 225, ensuring the stability of the structure. The bottom end of the telescopic rod 232 is plugged into the top end of the sleeve rod 231. This design allows the telescopic rod 232 to slide inside the sleeve rod 231, thereby facilitating the adjustment of the applicability height of the rolling device. The top of the telescopic rod 232 is fixedly connected to the two ends of the push rod 1 to form a sturdy support structure. If the operator is shorter, they can shorten the length of the telescopic rod 232 to make the position of the push rod 1 more suitable for their height. On the contrary, if the operator is taller, they can extend the length of the telescopic rod 232 to adapt to their height.

[0034] The push rod 1 and the telescopic rod 232 are integrally formed, which means that they are formed from the same material at one time, or are combined into a whole by welding, riveting or other fixing methods during the manufacturing process. This design improves the overall stability and durability of the structure, reduces the connection points between components, and thus reduces potential failure points.

[0035] The design of the limiter 24 is used to control the telescopic range of the telescopic rod 232 to prevent structural damage caused by excessive telescopic extension. Two sets of adjusting nuts 241 are respectively embedded in the opposite surfaces of the two sleeve rods 231, which is convenient for installing the adjusting screw 242. The outer wall of the adjusting screw 242 is threadedly connected with the inner circle of the adjusting nut 241, so that the adjusting screw 242 can rotate in the adjusting nut 241, and the bottom end is held and connected with the corresponding hole groove 243. The hole groove 243 is provided on the opposite surface of the telescopic rod 232. When the bottom end of the adjusting screw 242 is held in the hole groove 243, it can limit the telescopic length of the telescopic rod 232. In this way, the operator can adjust the length of the telescopic rod 232 as needed, but it will not exceed the safety range set by the adjusting screw 242 and the hole groove 243. The design of the limiter 24 enhances the safety and reliability of the lawn rolling device and ensures the stability and durability of the device in long-term use.

[0036] The working principle of the lawn rolling device is as follows: when the lawn needs to be rolled, the operator can add or reduce fillers 213 such as sand, water or other weight media to the rolling cylinder 211 as needed to adjust the weight of the roller 21. This can adapt to different types of lawns and soil conditions and ensure the rolling effect. By rotating the adjustment screw 242, the operator can adjust the length of the telescopic rod 232, thereby changing the extension of the telescopic rod 232. The adjustment screw 242 is then rotated in the opposite direction to support the corresponding hole groove 243, so that the adjusted telescopic rod 232 can be fixed. This design enables the lawn rolling device to adapt to the use of operators of different heights, improving the comfort and efficiency of operation. When the operator pushes the lawn rolling device, the integrated manufacturing design of the push rod 1 and the telescopic rod 232 ensures the stability of the structure. The rolling cylinder 211 rolls under the action of the hinge 22, exerting uniform pressure on the lawn soil.

[0037] It should be noted that the specific models and specifications of the rolling cylinder 211, filler 213, bearing 222, and adjusting screw 242 need to be selected and determined according to the actual specifications of the device, and the specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail.

[0038] It is obvious to those skilled in the art that the present application is not limited to the details of the exemplary embodiments described above, and that the present application can be implemented in other specific forms without departing from the spirit or essential features of the present application. Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects, and the scope of the present application is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present application. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
