Description

Technical Field

[0001] The utility model relates to the technical field of other special machinery specially suitable for land preparation with crops, in particular to a lawn loosening device. Background Art

[0002] In the construction of municipal gardens, greening planting is a relatively important urban garden construction. Greening planting usually includes lawn planting and tree planting. In lawn planting, the lawn needs to be loosened regularly during maintenance to avoid soil compaction and allow the roots of the grass to have sufficient air.

[0003] Different types of grass are planted on existing lawns, and the root lengths of different types of grass are also different. This leads to differences in the thickness of the soil turned over when the lawn is loosened. However, the position of the loosening roller of most existing loosening devices is fixed, which leads to the loosening roller being able to only turn over soil of a single thickness, thereby reducing the loosening effect of the loosening device on the lawn. Since the existing loosening roller needs to turn over the soil, the bottom of the loosening roller is lower than the horizontal position of the pulley. In this way, when the staff pushes the loosening device to move on the plane, the bottom of the loosening roller will contact the ground, which increases the difficulty for the staff to push the loosening device to move. In response to the above-mentioned problems, the utility model designs a lawn loosening device. Utility Model Content

[0004] The purpose of the utility model is to solve at least one of the technical problems existing in the prior art and to provide a lawn loosening device that can solve the problem that the loosening roller is fixed in position, so that the loosening roller can only turn over soil of a single thickness, thereby reducing the loosening effect of the loosening device on the lawn.

DETAILED DESCRIPTION

[0021] See also Figure 1-4 The utility model provides a technical solution: a lawn loosening device, including a body 1, four supporting legs 2 are fixedly connected at the four corners of the lower surface of the body 1, and pulleys are provided on the lower sides of the four supporting legs 2, so that the pulleys support the body and also facilitate the movement of the loosening device.

[0022] Furthermore, a loosening roller 3 is provided on the lower side of the vehicle body 1, and a plurality of blades are fixedly connected to the outer surface of the loosening roller 3, and a connecting shell 4 is provided on the opposite side surfaces of the loosening roller 3, and two control panels 5 are provided on the lower side of the vehicle body 1, and the two control panels 5 are respectively arranged on the two sides of the loosening roller 3 and there is no contact between the two, and the lower surface of the control panel 5 is rotatably connected to two rotating plates 6, and the other side of the rotating plate 6 is rotatably connected to the outer surface of the connecting shell 4, and two support plates 7 are fixedly connected to the lower surface of the vehicle body 1, and the two support plates 7 are respectively arranged on the outer sides of the two control panels 5, and a push rod cylinder 8 is fixedly connected to the surface of the support plate 7 facing the control panel 5, and one end of the telescopic rod of the push rod cylinder 8 is fixedly connected to the control panel 5, so by starting the push rod cylinder 8, the telescopic rods of the two push rod cylinders 8 can synchronously control the two control panels 5 to move relative to each other. When the two control plates 5 are displaced in relative directions, the control plate 5 will form a thrust on the rotating plate 6, and the rotating plate 6 will push the connecting shell 4 to move downward, thereby controlling the loosening roller 3 to move downward; when the two control plates 5 are displaced in opposite directions, the rotating plate 6 will form an upward pulling force on the connecting shell 4, so that the loosening roller 3 is synchronously displaced upward, and the purpose of controlling the loosening roller 3 to move upward or downward is achieved through the above structure. Therefore, the height of the loosening roller 3 can be adjusted according to the actual loosening needs of the lawn, further improving the practicability of the loosening device and ensuring the loosening effect on the lawn. At the same time, the loosening device can move the loosening roller 3 to the upper side of the pulley when moving, so the loosening roller 3 will not contact the ground, reducing the difficulty of the staff in pushing the loosening device to move.

[0023] Furthermore, a support slide bar 9 is fixedly connected between the two horizontal support legs 2, and the two control plates 5 are slidably mounted on the outer surface of the support slide bar 9. In this way, the support slide bar 9 forms a supporting effect on the control plate 5, thereby avoiding the problem of tilting of the control plate 5 as much as possible and ensuring the stability of the loosening roller 3 when adjusting its height.

[0024] Furthermore, a connecting shaft 11 is fixedly connected to the surface of the loosening roller 3 facing the connecting shell 4, and the other end of the connecting shaft 11 rotates and penetrates into the connecting shell 4. The connecting shaft 11 is located at one end of the connecting shell 4 and is fixedly connected to a bevel gear 12. A rotating shaft 10 is provided on the upper side of the connecting shell 4, and the lower end of the rotating shaft 10 rotates and penetrates into the connecting shell 4. The lower end of the rotating shaft 10 is also fixedly connected to a bevel gear 12. The two bevel gears 12 are meshed and connected. Therefore, by controlling the rotating shaft 10 to rotate, the two bevel gears 12 are meshed and transmitted, and the connecting shaft 11 is synchronously driven to rotate, thereby achieving the purpose of driving the loosening roller 3 to rotate.

[0025] Furthermore, a motor 13 is fixedly connected to the upper surface of the vehicle body 1, and the lower end of the output shaft of the motor 13 rotates and passes through the lower surface of the vehicle body 1. A control sleeve 14 is fixedly connected to the lower end of the output shaft of the motor 13. The control sleeve 14 is slidably sleeved on the outer surface of the rotating shaft 10. Two limiting slide grooves 15 are provided on the inner walls on both sides opposite to each other. Two limiting sliders 16 are fixedly connected to the outer surface of the rotating shaft 10 located inside the control sleeve 14. The limiting slider 16 is slidably connected to the limiting slide groove 15. When the loosening roller 3 is adjusted upward or downward, the rotating shaft 10 is synchronously moved in the control sleeve 14. The limiting slider 16 slides in the limiting slot 15. At the same time, since the rotating shaft 10 is restricted by the limiting slider 16, when the motor 13 starts and drives the control sleeve 14 to rotate, the rotating shaft 10 rotates synchronously driven by the limiting slider 16, thereby achieving the purpose of driving the loosening roller 3 to rotate. Through the above-mentioned structural setting, after the height of the loosening roller 3 is adjusted, the motor 13 can also drive the loosening roller 3 to rotate through the driving structure, without the need to specifically replace a certain component, thereby improving the efficiency and speed of adjusting the loosening roller 3.

[0026] Working principle: When the device is used, by starting the push rod cylinder 8, the telescopic rods of the two push rod cylinders 8 can synchronously control the two control plates 5 to move in relative or opposite directions. When the two control plates 5 move in relative directions, the control plate 5 will form a thrust on the rotating plate 6, and at the same time, the rotating plate 6 will push the connecting shell 4 to move downward, thereby controlling the loosening roller 3 to move downward. When the two control plates 5 move in opposite directions, the rotating plate 6 will form an upward pulling force on the connecting shell 4, so that the loosening roller 3 moves upward synchronously. The above structure is used to achieve the purpose of controlling the upward or downward displacement of the loosening roller 3.

[0027] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
