Description

Technical Field

[0001] The utility model relates to the technical field of greening, and more specifically, to a lawn loosening device. Background Art

[0002] A lawn is a densely planted patch of perennial, short, herbaceous plants, cultivated or maintained artificially for greening and beautification purposes. In modern gardens, lawns are often used for greening. Maintaining a lawn requires loosening the soil to increase the permeability and air permeability of the lawn's surface soil.

[0003] For example, patent publication number CN210406094U discloses a lawn loosening device for forestry greening projects, belonging to the technical field of forestry greening project equipment. The device comprises a fixed base, a battery pack mounted on the left side of the upper end of the fixed base, a fixed cylinder mounted in the middle of the upper end of the fixed base, a rotating inclined column mounted on the upper end of the fixed cylinder, a rotating shaft mounted on the upper end of the rotating inclined column, a driving pulley mounted in the middle of the rotating shaft, a lifting inclined column in contact with the lower end of the rotating inclined column, a lifting groove provided in the middle of the left end of the lifting inclined column, a lifting block provided in the lifting groove, a lifting shaft mounted in the middle of the lower end of the lifting inclined column, the lower end of the lifting shaft passing through the bottom end of the fixed cylinder and the fixed base, connected to a loosening plate, the loosening plates evenly provided with loosening needles, a walking frame mounted on the right side of the lower end of the fixed base, and a walking shaft mounted in the middle of the walking frame. This utility model enables the entire loosening device to move while in operation, while ensuring the loosening of the entire lawn, and the functional components of both movement and loosening utilize the same power system.

[0004] In the above patent, the inventor believes that although the patent loosens the soil by drilling holes on the surface of the lawn during use, the hollow holes are easily disappeared and closed due to human trampling. Therefore, the instability of the hollow holes on the lawn will affect the subsequent water permeability and air permeability of the lawn. Utility Model Content

[0023] See also Figure 1-Figure 4The present invention provides a lawn loosening device, which is arranged on a vehicle body, which is not shown in the figure. The vehicle body is mainly used as a mobile device for the lawn loosening device, which is convenient for walking operations on the lawn. It includes a mobile plate 1, a pair of fixed side plates 2 are fixedly connected to the bottom of the mobile plate 1, a fixed support rod 3 is fixedly connected to the pair of fixed side plates 2, an eccentric rotating shaft 4 is rotatably connected to the pair of fixed side plates 2, and a plurality of rotating sleeves 41 are rotatably connected to the eccentric rotating shaft 4. One of the fixed side plates 2 is provided with a rotating motor 5 for driving the eccentric rotating shaft 4 to rotate. The rotating motor 5 can be driven by a controller and an external power supply is required. Each rotating sleeve 41 is provided with a reciprocating transmission mechanism 1 6 and a reciprocating transmission mechanism 2 11. The reciprocating transmission mechanism 1 6 arranged on the rotating sleeve 41 is movably connected to the fixed support rod 3, and a loosening cone 7 is detachably connected to the reciprocating transmission mechanism 1 6. The end of the loosening cone 7 is pointed, which can facilitate drilling holes in the lawn.

[0024] The reciprocating transmission mechanism 6 includes a connecting rod 61 fixedly connected to the rotating sleeve 41 and a sliding rod 62 hinged to the connecting rod 61. The sliding rod 62 is slidably connected to the fixed support rod 3.

[0025] One end of the loosening cone 7 is fixedly connected with a threaded head 71, and the loosening cone 7 is threadedly connected to the slide rod 62 through the threaded head 71. The setting of the threaded head 71 can facilitate the disassembly, assembly and replacement of the loosening cone 7.

[0026] Specifically, the eccentric shaft 4 is driven to rotate by the rotating motor 5, and the eccentric shaft 4 can pull the rotating sleeve 41 to rotate on a limited path, so that the slide rod 62 can slide back and forth on the fixed support rod 3 to provide a reciprocating up and down movement for the loosening cone 7, so that the loosening cone 7 can punch holes in the surface of the lawn to form holes to loosen the lawn, which can promote the water permeability and air permeability of the lawn.

[0027] A sand storage box 8 is provided on the top of the movable plate 1, in which sand can be stored. The sand can be used to fill the holes on the lawn. The bottom of the sand storage box 8 is fixedly connected to a number of sand guide pipes 9, and the sand guide pipes 9 are fixedly connected to a sand discharge pipe 10. The sand discharge pipe 10 is located on one side of the loosening cone 7. A sand-taking rod 12 is provided on the reciprocating transmission mechanism 11, and the sand-taking rod 12 is movably connected to the sand guide pipe 9. A scraper 13 is suspended at the bottom of the movable plate 1, and the scraper 13 can be used to level the sand discharged through the sand discharge pipe 10.

[0028] The sand discharge pipe 10 and the loosening cone 7 are arranged in the same straight line. Such a position setting allows the sand discharged onto the lawn to be in the same straight line with the hole opened by the loosening cone 7, which facilitates accurate filling of the hole.

[0029] The sand taking rod 12 is slidably connected to the sand inlet pipe 9. A sand taking trough 121 is provided on the sand taking rod 12. The sand taking trough 121 is arranged facing the port of the sand discharge pipe 10, so that the sand in the sand taking trough 121 can be conveniently introduced into the sand discharge pipe 10. The inner bottom of the sand taking trough 121 is provided with a slope, and the setting of the slope can improve the thoroughness of sand discharge.

[0030] The bottom of the movable plate 1 is fixedly connected to a suspension rod 131 , and the scraper 13 is fixedly connected to one end of the suspension rod 131 .

[0031] Specifically, during the rotation of the eccentric shaft 4, the sand-taking rod 12 is slidably arranged in the sand-drawing pipe 9. The connecting rod 2 111 can drive the sliding rod 2 112 to provide a reciprocating motion for the sand-taking rod 12 through the cooperation of the rotating sleeve 41 and the eccentric shaft 4. In this way, the sand-taking rod 12 can slide back and forth in the sand-drawing pipe 9 and explore the sand storage box 8. The sand-taking trough 121 provided can be used to carry sand into the sand-drawing pipe 9. With the function of connecting the sand-drawing pipe 9 and the sand-discharging pipe 10, the sand can be discharged to the rear of the hole through the sand-discharging pipe 10. Because the entire lawn loosening device can be moved by the vehicle body, the movement of the scraper 13 can level the sand and fill the sand into the holes formed by the loosening cone 7 on the lawn. By filling the holes with sand, the problem of the holes being closed due to human trampling can be prevented.
