Description

Technical Field

[0001] This utility model relates to the field of lawn maintenance equipment technology, specifically a device that facilitates lawn aeration and loosening. Background Technology

[0002] A lawn aerator is a specialized piece of equipment used for lawn maintenance. Its core function is to mechanically create evenly distributed holes in the lawn soil, thereby breaking up soil compaction, enhancing soil aeration, promoting water penetration and root respiration, and ultimately improving the lawn's growth. In landscaping, sports field maintenance, and municipal lawn care, this type of device is one of the key pieces of equipment for ensuring healthy lawn growth. With the increasing demand for refined lawn maintenance, the necessity of aeration and loosening the soil has become increasingly apparent. Over time, lawn soil is prone to compaction due to trampling, irrigation, and other factors, leading to root hypoxia, hindered nutrient absorption, and consequently, yellowing and wilting. Aeration effectively breaks up this compaction, increases soil porosity, creates a suitable environment for root growth, promotes efficient use of fertilizers and water, and reduces maintenance costs. Currently, most lawn aeration and soil loosening devices on the market have fixed installation structures for their aeration components, or can only achieve depth adjustment through cumbersome mechanical disassembly and replacement of aeration rods of different lengths. The operation process is complicated and time-consuming, making it difficult to quickly switch the aeration depth according to different lawn types (such as cool-season lawns and warm-season lawns), soil hardness, and growth stages. This seriously affects the efficiency and adaptability of the operation and fails to meet the actual needs of refined maintenance. Utility Model Content

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.

[0013] Please see Figure 1-3 This utility model provides a technical solution: a device for facilitating lawn aeration and loosening, comprising: The bracket 1 is in the shape of an inverted "U". A pair of hollow connecting cylinders 4 are rotatably mounted on the bracket 1. A pair of rotating wheels 10 are mounted on the pair of connecting cylinders 4. A hollow rotating cylinder 5 is mounted between the pair of connecting cylinders 4. When the rotating wheels 10 rotate, they can drive the pair of connecting cylinders 4 to rotate, and the pair of connecting cylinders 4 drive the rotating cylinder 5 to rotate. A rotating shaft 7 is rotatably disposed in a pair of connecting cylinders 4. At least one connecting cylinder 4 is provided with a shaft locking device 6 for fixing the rotating shaft 7. The rotating shaft 7 is used to operate the adjustment assembly to adjust the extension length of each punching rod 9. The rotating shaft 7 is locked and fixed by the shaft locking device 6, thereby fixing the position of multiple punching rods 9. Multiple sets of punch rods 9 are provided, each set of punch rods 9 is set on the rotating cylinder 5 and can move radially along the rotating cylinder 5. Multiple sets of punch rods are set on the rotating cylinder 5 and are arranged at equal intervals along the axial direction of the sleeve 11. Multiple sets of adjustment components for adjusting the position of the punch rods 9 are provided inside the rotating cylinder 5.

[0014] As one embodiment of this utility model, each set of adjustment components includes: Multiple sets of sleeves 11 are fixed and evenly arranged in the radial direction of the rotating cylinder 5, and the punching rod 9 is slidably arranged inside the sleeve 11. Multiple rotating plates 15 are equally spaced on the rotating shaft 7 and located inside the rotating cylinder 5. Each rotating plate 15 has multiple arc-shaped grooves 16. The end of the punching rod 9 located inside the sleeve 11 is provided with a sliding rod 14. A sliding groove is provided on the side wall of the sleeve 11. The sliding rod 14 is slidably disposed in the arc-shaped groove 16 and the sliding groove. Multiple limiting rings 13 are provided, each of which is mounted on the punch rod 9 and located inside the sleeve 11; Multiple springs 12 are fitted on the punch rod 9. Each spring 12 is located inside the sleeve 11 with one end abutting against the inner wall of the sleeve 11 and the other end abutting against the limiting ring 13.

[0015] As an embodiment of this utility model, a bearing 3 is provided between the bracket 1 and the connecting cylinder 4. The bearing 3 is used to reduce the friction generated when the connecting cylinder 4 rotates relative to the bracket 1.

[0016] As an embodiment of this utility model, a handwheel 8 is provided at one end of the rotating shaft 7, and the operator rotates the handwheel 8 to operate the rotating shaft 7.

[0017] As one embodiment of this utility model, a pull rod 2 is provided on the bracket 1, and a person pulls the pull rod 2 to move the bracket 1.

[0018] Those skilled in the art should connect all electrical components and their compatible power supplies in this case via wires, and should select appropriate controllers according to actual conditions to meet control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical connections between the various electrical components are completed in sequence. The detailed connection methods are well-known technologies in the field. The following mainly introduces the working principle and process, and will not describe the electrical control further.

[0019] The working principle and usage process of this utility model are as follows: When in use, the operator rotates the handwheel 8, which drives the rotating shaft 7 to rotate. The rotating shaft 7 drives the connected multiple rotating plates 15 to rotate. When the rotating plates 15 rotate, the sliding rod 14 rotates in the groove on the arc groove 16 and the sleeve 11, thereby causing the sliding rod 14 to drive the drilling rod 9 to move radially in the rotating cylinder 5. When the drilling rod 9 moves, it can drive the limiting ring 13 to move. The limiting ring 13 causes the spring 12 sleeved on the drilling rod 9 to deform. After the positions of the multiple drilling rods 9 are adjusted, the position of the rotating shaft 7 is fixed by the shaft locking device 6. The operator pulls the pull rod 2 to move, which drives the bracket 1 to move. The bracket 1 drives a pair of rotating wheels 10 to rotate. When the pair of rotating wheels 10 rotate, they drive a pair of connecting cylinders 4 to rotate. The pair of connecting cylinders 4 drive the rotating cylinder 5 to rotate, which drives the multiple drilling rods 9 to rotate, thereby causing the multiple drilling rods 9 to drill holes and loosen the soil in the lawn.

[0020] This invention allows operators to rotate a shaft 7 to adjust the extension length of multiple punching rods 9, and then use a shaft locking device 6 to fix the position of the shaft 7, thereby fixing the position of the multiple punching rods 9. This makes the operation convenient, allows for quick switching of punching depth, and improves the adaptability of the device.

[0021] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
