Technical Field
[0001] The utility model relates to the technical field of highway construction, in particular to a sand and gravel desludging device for highway construction. Background Art
[0002] In highway construction, sand and gravel are important materials that constitute the base and surface layers of the highway. Their quality and performance directly affect the durability, bearing capacity and service life of the highway. Through desludging treatment, the soil, organic matter and other impurities in the sand and gravel can be removed, thereby improving the purity and quality of the sand and gravel, which helps to improve the mechanical properties and stability of the highway.
[0003] Traditional sand and gravel desludging devices mostly use a simple screening method, which uses a vibrating screen or a fixed screen to screen the sand and gravel to remove the dirt on the surface of the sand and gravel. However, this method exposes some problems in actual application, which affects the desludging effect. For example, it is difficult to remove the dirt attached to the surface of the sand and gravel. This attached dirt not only reduces the quality of the sand and gravel, but also affects the strength and durability of the concrete. Therefore, a sand and gravel desludging device for highway construction is proposed to solve the above problems. Utility Model Content

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:
[0006] A sand and gravel desludging device for highway construction includes a scrubbing box with a rotating scrubbing structure provided inside the scrubbing box;
[0007] The rotating mud brush structure includes two fixed cylinders rotatably mounted on the front and rear walls of the scrubbing box, a screen cylinder located inside the scrubbing box is rotatably mounted between the two fixed cylinders, a guide spiral belt is fixedly mounted on the inner wall of the screen cylinder, a three-pronged bracket is fixedly mounted near the top of the two fixed cylinders, a rotating shaft located inside the screen cylinder is rotatably mounted inside the two three-pronged brackets, a wire brush located inside the screen cylinder is fixedly mounted outside the rotating shaft, the wire brush is located on the inner side of the guide spiral belt, a concave plate is fixedly mounted on the top of the scrubbing box, and a driving structure is provided on the top of the concave plate;
[0008] The driving structure includes a motor fixedly mounted on the top of the concave plate, the motor is located in the front groove of the concave plate, a driving rod is fixedly mounted on the output end of the motor, a gear is fixedly mounted on the outside of the driving rod, a gear ring meshing with the bottom of the gear is welded on the outer wall of the screen cylinder, a No. 1 belt pulley is fixedly mounted in front of the driving rod, a No. 2 belt pulley located below the No. 1 belt pulley is fixedly mounted in front of the rotating shaft, and a transmission belt is sheathed on the outside of the No. 1 and No. 2 belt pulleys.
[0009] The beneficial effects of the utility model are as follows: after water is added to the inside of the scrubbing box, sand and gravel are added into the screen drum from the back, and the motor drives the gear to rotate, driving the screen drum and the internal sand and gravel to rotate, and the surface dirt is removed by the mutual friction of the sand and gravel in the water.
