Description

Technical Field

[0001] The utility model relates to the field of construction tools, in particular to a ground leveling device for construction. Background Art

[0002] During the construction of a building site or road, it is usually necessary to level the road surface or the ground soil. The land leveling effect will affect the quality of cement pouring in the later stage. At the same time, insufficient flatness or uneven soil layer will easily lead to the cement layer breaking after pouring cement due to the uneven support of the soil layer on the cement layer. Therefore, before pouring cement, the flatness of the construction site is very important for the quality of later pouring.

[0003] At present, the commonly used method of leveling construction land mainly uses excavators to level the road surface or the ground. However, in places with small construction areas, the construction operations of excavators are limited and can only be leveled manually. Therefore, small-scale land leveling equipment for construction land came into being. The commonly used land leveling devices on the market usually use multi-tooth types to perform rotary tillage and leveling of the ground. When using multi-tooth leveling equipment, due to the sparse tooth structure, it is easy to cause depressions at the position where the rotating teeth pass after leveling, which is inconvenient for the next step of land compaction. Utility Model Content

[0004] In view of the problems existing in the background technology, the utility model proposes a ground leveling device for construction, which adopts a two-stage rotary tillage method. The soil is rotary tilled once by a multi-tooth support arm, and then the soil is leveled by a plate-shaped support arm, so as to improve the soil flatness of the construction ground and facilitate the subsequent soil compaction operation.

[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a ground leveling device for construction, comprising a bracket, the bracket comprising a lower plate and an upper plate, the lower plate is fixedly mounted with a guide rod perpendicular to the lower plate, the upper plate and the lower plate are configured to form a spacing and are slidably connected to the guide rod; the lower plate is also rotatably connected with an adjustment rod, the adjustment rod is threadedly connected to the upper plate, and the upper plate is moved away from the lower plate by rotating the adjustment rod; and

[0006] A leveling component rotatably mounted on the upper plate body, wherein a boss and an arm seat a are fixedly mounted on the rotating shaft of the leveling component, an arm seat b is also slidably connected to the rotating shaft between the arm seat a and the boss, and the arm seat b is threadedly connected to a screw rotatably connected to the arm seat a and the boss; a first arm and a second arm are respectively fixedly mounted on the arm seat a and the arm seat b, and plow-shaped teeth downwardly arranged along the plumb direction are arranged on the first arm at intervals, and plate-shaped teeth are arranged on the second arm; the screw can be rotated to drive the arm seat to move downward along the plumb direction, so that the end of the plate-shaped tooth extends out of the end of the plow-shaped tooth;

[0007] Furthermore, the end of the plow-shaped teeth is inclined downward along the rotary tillage direction of the leveling assembly, and the end of the plate-shaped teeth is inclined downward away from the rotary tillage direction of the entire assembly;

[0008] Furthermore, the construction ground leveling device further comprises a motor, the motor shaft of which is fixedly connected to the rotating shaft of the leveling assembly;

[0009] Furthermore, the lower plate body is provided with an opening for the leveling assembly to pass up and down, and a moving wheel is provided at the bottom of the lower plate body.

[0010] The beneficial effects of the utility model are as follows: when the utility model is in use, the motor is started to rotate the leveling component, and the adjusting rod is manually adjusted to move the upper plate body downward.

DETAILED DESCRIPTION

[0017] In order to make the purpose, technical solution and beneficial effects of the present invention clearer, the preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings to facilitate understanding by technicians.

[0018] As shown in the figure, direction A is downward along the plumb bob, and direction B is the rotary tillage direction of the leveling assembly.

[0019] like Figures 1 to 5 The figure shows a ground leveling device for construction, which mainly includes a bracket 1, and the bracket 1 includes a lower plate body 101 and an upper plate body 102. A guide rod 1012 perpendicular to the lower plate body 101 is fixedly installed on the upper end surface. A spacing is formed between the upper plate body 102 and the lower plate body 101, and the upper plate body 102 is slidably connected to the guide rod 1012. In order to improve stability, the guide rod 1012 can be set to a plurality of guide rods, and a limit bolt (not shown in the figure) can be set on the guide rod 1012. After the upper plate body 102 moves a certain distance along the plumb bob direction, it is fixed by the limit bolt. The lower plate body 101 is also rotatably connected to an adjustment rod 2, and the adjustment rod 2 is threadedly connected to the upper plate body 102. Rotating the adjustment rod 2 moves the upper plate body 102 away from or close to the lower plate body 101. The end of the adjustment rod 2 is set to be a rotating hand wheel. By rotating the hand wheel to rotate the adjustment rod 2, the force of manual adjustment can be reduced.

[0020] like Figures 2 to 5 The construction ground leveling device shown also includes a leveling assembly 4 rotatably mounted on the upper plate 102, a boss 3011 and an arm seat a403 are fixedly mounted on the rotating shaft 301 of the leveling assembly 4, and an arm seat b404 is slidably connected to the rotating shaft 301 between the arm seat a403 and the boss 3011. The arm seat b404 is threadedly connected to a screw rod 4041 rotatably connected to the arm seat a403 and the boss 3011, and the screw rod 4041 can be rotated to adjust the arm seat b404 to slide back and forth between the arm seat a403 and the boss 3011.

[0021] like Figures 1 to 4 The shown construction ground leveling device also includes a motor 3, a motor shaft of the motor 3 is fixedly connected to the rotating shaft 301 of the leveling component 4, and the motor 3 is fixedly installed on the upper plate body 102. When in use, the upper plate body 102 can be moved downward by rotating the adjusting rod 2, and the motor 3 and the leveling component 4 can be further adjusted to move downward.

[0022] like Figure 1 , 2The lower plate 101 is provided with an opening 1011 for the leveling assembly 4 to pass up and down. When the leveling assembly 4 is adjusted to move downward, the leveling assembly 4 can move downward through the opening 1011, so that the leveling assembly 4 can contact the ground and level the soil. The bottom of the lower plate 101 is provided with a moving wheel 1013, and the upper plate 102 or in some preferred embodiments, the lower plate 101 is fixed with a handrail 1021 (not shown in the figure). During the construction of leveling the land, the whole device can be pushed to move by holding the handrail 1021, so as to perform a small area of ​​land leveling operation.

[0023] like Figure 5 The arm seat a403 and the arm seat b404 are respectively fixedly mounted with a first arm 401 and a second arm 402, and the first arm 401 is provided with a plough-shaped tooth 4011 downward along the plumb direction at intervals, and the second arm 402 is provided with a plate-shaped tooth 4021. The motor 3 can be started so that the plough-shaped tooth 4011 or the plate-shaped tooth 4021 can be respectively rotated to perform a rotary tillage and leveling operation on the land, and can also be rotated at the same time to perform a rotary tillage and leveling operation on the construction land. When in use, the screw 4041 rotates to drive the arm seat to move downward along the plumb direction, so that the end of the plate-shaped tooth 4021 extends out of the end of the plough-shaped tooth 4011, thereby switching the plough-shaped tooth 4011 or the plate-shaped tooth 4021 to contact the ground, and performing a secondary leveling operation on the construction land. During construction, the plough-shaped tooth 4011 can first be used to perform rotary tillage and crushing on the ground soil layer, and then the plate-shaped tooth 4021 can be switched to level the soil layer.

[0024] like Figure 5 The end of the plow-shaped tooth 4011 is tilted downward along the tillage direction of the leveling component 4, which can improve the crushing efficiency of the soil layer, while the end of the plate-shaped tooth 4021 is tilted downward away from the tillage direction of the entire component, so that during the soil leveling process, the resistance of the soil to the plate-shaped tooth 4021 is reduced, further reducing the load of the motor 3.

[0025] When the utility model is used, the motor 3 is started to rotate the leveling component 4, and the adjusting rod 2 is manually adjusted to move the upper plate body 102 downward. When the plow-shaped teeth 4011 of the first arm 401 are embedded in the soil layer, the soil layer can be rotary tilled to break the soil. After the rotary tillage is completed, the adjusting rod 2 is rotated to move the upper plate body 102 upward, so that the plow-shaped teeth 4011 are separated from the soil layer, and then the plate-shaped teeth 4021 are moved downward by adjusting the screw 4041, so that the end of the plate-shaped teeth 4021 extends downward and exceeds the end of the plow-shaped teeth 4011, and is embedded in the soil layer to level the soil depression caused by the plow-shaped teeth 4011, thereby facilitating the next step of compacting the soil on the construction site. The utility model can crush and level the soil, and can improve the flatness of the soil on the construction site.

[0026] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the utility model.
