Description

Technical Field

[0001] The utility model relates to the field of land leveling devices, in particular to a land leveling device. Background Art

[0002] Ground leveling is of vital importance. On the one hand, it can lay a solid and stable foundation for various subsequent projects and ensure the quality and safety of the projects. Whether it is construction or road paving, a flat ground can make the building stand more firmly and effectively reduce the uneven structural stress caused by uneven ground.

[0003] In the process of land leveling, the land leveling device plays a vital role. A common land leveling device currently on the market is mainly composed of a ramming head, a connecting rod, an electric motor and other parts. The motor drives the ramming head up and down with the help of the connecting rod, thereby generating an impact force on the ground, and compacting loose soil, sand and gravel and other materials with a powerful impact force. This device has the advantages of simple structure and easy operation, and plays a positive role in land leveling operations.

[0004] However, this common existing land leveling device has certain disadvantages. When not in use, due to its heavy overall weight, it often requires at least two operators to carry out the lifting and loading and unloading of the device. This process is extremely laborious and inconvenient, so it needs to be improved. Utility Model Content

Moreover, the cooperation between the slider and the shock absorber can play a good shock-absorbing role when encountering uneven roads during transportation, protecting the device body and internal components from damage, and extending the service life of the device.

[0008] Furthermore, the sliders are symmetrically arranged on both sides of the device body, and a sliding groove corresponding to the sliders is opened inside the device body.

[0009] By adopting the above technical solution, when encountering uneven road surface during transportation, the slider can slide smoothly in the device body, thereby achieving the purpose of shock absorption.

[0010] Furthermore, the sleeve is located outside the device body, and two groups of sleeves are symmetrically arranged, and a through groove for the lifting rod to slide is opened inside the sleeve.

When in use, the lifting rod 4 is raised to ensure that the device is stable and the protective plate 5 can effectively protect the operator's legs when the device is working, reducing the risk of accidents and greatly improving the safety of operation. The outer wall of the sleeve 3 is rotatably installed There is a connecting rod 51 rotatably connected to the outer wall of the protective plate 5, a connecting block 42 is fixedly installed on the outer wall of the lifting rod 4, and an electric push rod 6 whose end is connected to the connecting block 42 is fixedly installed on the outer wall of the device body 1, so that the electric push rod 6 can accurately control the lifting and lowering of the lifting rod 4, thereby easily realizing the switching of the device between the movable state and the working state. A shock absorber 21 corresponding to the slider 2 is provided in the device body 1. The cooperation between the slider 2 and the shock absorber 21 can play a good shock-absorbing role when encountering uneven roads during transportation, protect the device body 1 and internal components from damage, and extend the service life of the device.

[0030] See also Figure 3 and Figure 4 The sliders 2 are symmetrically arranged on both sides of the device body 1. A sliding groove corresponding to the sliders 2 is opened inside the device body 1, so that when encountering uneven roads during transportation, the sliders 2 can slide smoothly in the device body 1, thereby achieving the purpose of shock absorption.

[0031] See also Figure 1 - Figure 4 The sleeve 3 is located outside the device body 1, and two groups of sleeves 3 are symmetrically arranged, and a through groove for the lifting rod 4 to slide is opened inside the sleeve 3, so that the lifting rod 4 can be lifted and lowered smoothly, thereby enhancing stability.

[0032] See also Figure 1 - Figure 4 There are two groups of lifting rods 4 symmetrically arranged, and the length of the lifting rods 4 is greater than the distance between the sleeve 3 and the bottom of the device body 1, so that after the lifting rods 4 are unfolded, the universal wheels 41 can fully contact the ground, thereby achieving the purpose of convenient transportation.

[0033] See also Figure 1 - Figure 4 The cross section of the protective plate 5 is T-shaped, and the surface of the protective plate 5 is made of silicone material, so that the protective plate 5 will not be hindered when rotating, and the silicone material will not cause damage to the operator, thereby achieving effective protection.

[0034] See also Figure 3 and Figure 4 The shock absorber 21 is symmetrically arranged at both ends of the slider 2, and one end of the shock absorber 21 is in contact with the slider 2, and the other end of the shock absorber 21 is in contact with the inside of the device body 1, so that it can play a good shock-absorbing role when encountering uneven roads during transportation, protecting the device body 1 and internal components from damage, and extending the service life of the device.

[0035] See also Figure 1 - Figure 4 The connecting block 42 is located between the two sets of lifting rods 4, and the top of the connecting block 42 fits with the bottom of the sleeve 3, so that the electric push rod 6 pushes the connecting block 42 to achieve the lifting and lowering of the two sets of lifting rods 4, increasing the convenience of operation.

[0036] The working principle of the present utility model is as follows: when it is necessary to move the device main body 1, the electric push rod 6 is first started. At this time, the electric push rod 6 pushes the connecting block 42, prompting the lifting rod 4 to slide downward in the sleeve 3. As the lifting rod 4 descends, the angle of the connecting rod 51 changes, thereby driving the protective plate 5 to rotate upward between the lifting rods 4 until the universal wheel 41 contacts the ground and the protective plate 5 is fully retracted. Then, the device main body 1 is tilted to the side of the handle, so that the movement and transportation of the device main body 1 can be easily achieved. During the transportation process, if an uneven road surface is encountered, the slider 2 will slide up and down under the action of the shock absorber 21, thereby achieving the purpose of shock absorption. When the device main body 1 needs to be used, the electric push rod 6 is turned on again to make the lifting rod 4 rise. During the rising process, the connecting rod 51 is squeezed, and the protective plate 5 is reopened. When the lifting rod 4 is completely retracted, the protective plate 5 can protect the operator's legs.

The specific features, structures, materials, or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and purpose of the present invention, but as long as they are within the scope of the claims of the present invention, they are protected by patent law.
