Description

Technical Field

[0001] This utility model relates to the technical field of earthwork leveling equipment, and more specifically, to an earthwork leveling device. Background Technology

[0002] A grader is an earthmoving machine that uses a scraper to level the ground. The scraper is installed between the front and rear axles of the machine and can be raised, lowered, tilted, rotated and extended. Its movements are flexible and accurate, and it is easy to operate. It has a high precision in leveling the site and is widely used in land leveling work.

[0003] A search revealed a Chinese patent application with patent number 202321577198.0, which discloses an earthwork leveling device. The device includes a frame, on which a straight shaft for transmission is rotatably mounted on the bottom surface of the frame. Multiple straight shafts are provided. A shaped column for connection is fitted to the end of the straight shaft away from the frame. A tube seat for auxiliary support is slidably mounted to the end of the shaped column away from the straight shaft. A disc seat for connection is fitted to the end of the tube seat away from the shaped column. A slot for connection is provided to the end of the disc seat away from the tube seat. A plate for earthwork leveling is fitted to the inside of the slot by bolts.

[0004] While the aforementioned patent allows for adjustment based on usage needs, making it easier to move the earthmoving leveling equipment for soil leveling, the following shortcomings still exist during use: 1. When using the plate to level soil, if the soil is hard, the plate encounters significant resistance during the leveling process. This not only reduces work efficiency but also easily damages the plate structure, affecting the equipment's lifespan and operational continuity; 2. During soil leveling, the plate is not easily adaptable to changes in terrain and soil conditions, thus affecting the overall leveling effect and hindering the improvement of work quality and efficiency.

[0005] Therefore, there is an urgent need for an earthwork leveling device to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide an earthwork leveling device to solve the problems mentioned in the background art.

[0007] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0028] like Figure 1-4 As shown, the earthwork leveling device proposed in this embodiment includes a pusher 100 and a leveling frame 101 fixedly connected to the top wall of the pusher 100.

An arc-shaped ring 107 is also fixedly connected to one end of the soil-removing shaft 105 that passes through the soil-breaking frame 102. Under the action of the crushing shaft 103 and the soil-removing shaft 105, the soil loosening effect is improved, making it more practical.

[0030] like Figure 1-4 As shown, in a preferred embodiment, based on the above method, a support plate 110 is fixedly connected to the side wall of the height adjustment plate 109, a first rotating shaft 111 is rotatably connected to the side wall of the support plate 110, and a protective shell 112 is fixedly connected to the side wall of the support plate 110. The protective shell 112 can protect the first bevel gear 113 and the second bevel gear 115, making it more convenient to use.

[0031] like Figure 1-5 As shown, in a preferred embodiment, based on the above method, a first bevel gear 113 is fixedly connected to one end of the first rotating shaft 111 that passes through the protective shell 112, and a second rotating shaft 114 is rotatably connected to the top wall of the protective shell 112. A second bevel gear 115 is fixedly connected to one end of the second rotating shaft 114 that passes through the protective shell 112. The first bevel gear 113 and the second bevel gear 115 are meshed and connected. The transmission of driving force can be realized through the arrangement of the first bevel gear 113 and the second bevel gear 115, thereby improving synchronization.

[0032] like Figure 1-4As shown, in a preferred embodiment, based on the above method, a reciprocating handle 116 is fixedly connected to the top wall of the second rotating shaft 114. The reciprocating handle 116 is slidably connected to the inner wall of the arc-shaped ring 107. The crushing shaft 103 is connected to the first rotating shaft 111 via a pulley group 117. A drive motor 118 is fixedly connected to the side wall of the height adjustment plate 109. The output end of the drive motor 118 is fixedly connected to the crushing shaft 103. By sliding the reciprocating handle 116 on the inner wall of the arc-shaped ring 107, the soil-removing shaft 105 can be driven to reciprocate, which is beneficial to improving work efficiency.

[0033] like Figure 1-5 As shown, in a preferred embodiment, based on the above method, the side wall of the leveling frame 101 is further provided with an adjustment groove 120. There are two adjustment grooves 120 symmetrically arranged about the central axis of the leveling frame 101. The side wall of the leveling frame 101 is slidably connected to a lifting frame 121 through the adjustment groove 120. The side wall of the lifting frame 121 is rotatably connected to a leveling plate 122. Under the action of the lifting frame 121, it can adapt to different usage locations and has stronger applicability.

[0034] like Figure 1-5 As shown, in a preferred embodiment, based on the above method, a first electric push rod 123 is rotatably connected to the side wall of the lifting frame 121. The output end of the first electric push rod 123 is rotatably connected to the flat plate 122. The flat plate 122 can be deflected by the first electric push rod 123, which is beneficial to adapting to different construction sites.

[0035] like Figure 1-3 As shown, in a preferred embodiment, based on the above method, a second electric push rod 124 is fixedly connected to the top wall of the leveling frame 101. The output end of the second electric push rod 124 is fixedly connected to the lifting frame 121. The second electric push rod 124 can drive the lifting frame 121 to move up and down, which is beneficial to improving the convenience of use.

[0036] like Figure 1-4 As shown, in a preferred embodiment, based on the above method, a third electric push rod 125 is fixedly connected to the top wall of the soil breaking frame 102. The output end of the third electric push rod 125 is fixedly connected to the height adjustment plate 109. The height of the height adjustment plate 109 can be adjusted by the third electric push rod 125, thereby adjusting the soil loosening depth to achieve the best working effect.

[0037] Specifically, in use, the device works as follows: First, the second electric push rod 124 is activated to drive the lifting frame 121 to slide downwards. After the lifting frame 121 adjusts the leveling plate 122 to a suitable height, the third electric push rod 125 drives the height adjustment plate 109 to move upwards. The height adjustment plate 109 drives the breaking blade 104 and the soil-inserting blade 106 to insert into the soil to loosen it. Then, the trolley frame is pushed to move. When the trolley frame moves, the drive motor 118 is activated to drive the breaking shaft 103 to rotate. When the breaking shaft 103 rotates, the breaking blade 104 loosens the soil and drives the first rotating shaft 111 to rotate via the pulley assembly 117. When the first rotating shaft 111 rotates, the first bevel gear 113... The second bevel gear 115 is driven to rotate, which in turn drives the second rotating shaft 114 to rotate. The reciprocating handle 116 on the second rotating handle slides on the inner wall of the arc ring 107, which in turn drives the soil-pulling shaft 105 to reciprocate. When the soil-pulling shaft 105 swings, it drives the soil-inserting blade 106 to penetrate into the soil and then pull it out, which helps to improve the soil loosening effect. Then, when pushing the pusher 100, the leveling plate 122 scrapes the soil flat, which helps to improve the efficiency of soil leveling. At the same time, the first electric push rod 123 can be activated to push the leveling plate 122 to deflect, thereby realizing the adjustment of the deflection angle of the leveling plate 122, which is conducive to adapting to different application sites.
