[0019] The following is a detailed description of the embodiments of the present invention with reference to the accompanying drawings. DETAILED DESCRIPTION

[0020] The present invention will be further described below in conjunction with the accompanying drawings and embodiments:

[0021] like Figure 1 to Figure 3 As shown, a reusable construction site clearing device is characterized in that it includes: a skeleton 1, steel rake teeth 2, a screen 3 and a connecting shaft 4, the skeleton 1 and the screen 3 are fixedly connected by skeleton bolts 5, the steel rake teeth 2 are welded to the bottom of the skeleton 1, the screen 3 includes a transverse screen 31 and two end side screens 32, the tooth tips of the steel rake teeth 2 are directed toward the front and downward away from the transverse screen 31, and the connecting shaft 4 is connected to the skeleton 1 by a connecting shaft bolt 6.

[0022] Specifically, the frame 1 and the steel rake teeth 2 contact and rub against the ground, scraping the plants and stones on the surface of the soil layer when moving, and the screen 3 mainly performs the function of screening sand and garbage, grass and trees and storing a certain amount of garbage, grass and trees. The connecting shaft 4 can be connected to the tail of the tractor, and the tractor is driven to complete the surface clearing work.

[0023] The frame 1 includes a front top frame 11, a front bottom frame 12 and a side frame 13. The front top frame 11 is a door-shaped frame made by welding three angle steels. The front bottom frame 12 is a strip steel plate. The front bottom frame 12 is welded to the bottom of the front top frame 11. The side frame 13 is an arc angle steel.

[0024] Specifically, after the device skeleton 1 is manufactured, the screen 3 can be installed by the skeleton bolts 5. If the screen 3 is damaged, it can be replaced in time.

[0025] The transverse screen 31 is formed by bending a whole piece of perforated steel plate or steel wire mesh, and the end side screen 32 is formed by cutting a perforated steel plate or steel wire mesh according to the shape and size of the side frame 13 .

[0026] Specifically, the length and height can be flexibly selected according to actual needs during use. The size of the mesh holes of the screen 3 is determined according to project requirements, soil conditions, etc.

[0027] The connecting shaft 4 includes: a vertical shaft 41, a force transmission rod 42, and a connecting pair 43. The top of the vertical shaft 41 is fixedly connected to the middle of the front end top frame 11, the bottom of the vertical shaft 41 is fixedly connected to the middle of the front end bottom frame 12, one end of the force transmission rod 42 is fixedly connected to the middle of the vertical shaft 41, and the other end of the force transmission rod 42 is fixedly welded to the connecting pair 43.

[0028] Specifically, the surface clearing task is achieved by connecting the connecting pair 43 to the rear end of the tractor through bolts.

[0029] The transverse screen 31 has a transverse length of 1.8-2.2 m, a molding height of 0.3-0.6 m, a front-to-rear width of 0.4-1.0 m after molding, and a perforated steel plate or steel wire mesh thickness of 1-3 mm.

[0030] The steel rake teeth 2 are made of a steel plate with a thickness of 5 mm. The angle between the plate surface direction of the steel rake teeth 2 and the horizontal direction is 15°-45°. The length from the bottom edge to the tooth top of the steel rake teeth 2 is set to 3-10 cm. The number of teeth of the steel rake teeth 2 is determined according to the length of the device. The steel rake teeth 2 are made of 16Mn steel plate Q345B.

[0031] The specification of the angle steel used for the front top frame 11 is 50×50×5, the width of the strip steel plate used for the front bottom frame 12 is 5 cm and the thickness is 5 mm, and the specification of the arc angle steel used for the side frame 13 is 50×50×5.

[0034] In summary, the device is connected to the rear end of the tractor by bolts through the connection pair 43, and the device is dragged by the tractor, so that the frame 1 and the steel rake teeth 2 are in contact with the ground and rubbed. When moving, the steel rake teeth 2 scrape the plants and rocks on the surface of the soil layer, and the screen 3 collects the plants and rocks and filters out the sand. The present invention solves the shortcomings of conventional surface clearing machinery, such as high cost, slow surface clearing speed and incompleteness. The connecting bolts, angle steels, steel plates and wire meshes are all easy-to-obtain and can be purchased as finished products. After being hung on the back of a small tractor, the on-site surface clearing operation can be carried out. After the surface clearing operation is completed, it only needs to be unloaded from the back of the tractor and can be reused for the next construction.

[0035] The present invention is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as various improvements are made using the method concept and technical solution of the present invention, or are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
