Description

Technical Field

[0001] This utility model relates to the field of crushed stone and soil separation technology, specifically a crushed stone and soil separation device for roadbed excavation. Background Technology

[0002] Roadbed excavation refers to earthwork excavation operations carried out during the construction of infrastructure such as highways, railways, and airports to establish a stable roadbed. The main purpose of roadbed excavation is to provide sufficient bearing capacity and stability for the roadbed, while ensuring good drainage to extend its service life. Roadbed excavation gravel-soil separation equipment is a specially designed device for separating earth and gravel. It is commonly used in the construction of infrastructure such as highways, railways, and airports. It can improve construction efficiency, reduce the amount of manual sorting work, and help to effectively utilize and manage materials at the construction site.

[0003] Existing stone-soil separation devices typically use screens to separate and filter stones and soil. However, in actual use, the screens are easily clogged by soil, resulting in slow separation and longer separation time, which reduces the efficiency of stone-soil separation. Utility Model Content

[0025] One of the two vertical plates 11 and one of the two second fixed seats 13 are rotatably mounted with a first sprocket 20. One end of each of the two connecting shafts 14 passes through one of the two second fixed seats 13 and is fixedly connected to one of the two first sprockets 20 respectively.

[0029] It should be noted that this utility model is a roadbed excavation crushed stone and soil separation device. In use, the crushed stone and soil are poured into the separation frame 4, and then the motor 19 is started. The specific model of the motor 19 is not described here; the appropriate model depends on the equipment. The motor 19 will drive one of the connecting shafts 14 to rotate, thereby driving the first sprocket 20 to rotate. Then, the first chain 21 drives the second sprocket 20 to rotate, causing one of the rotating shafts 22 to drive one of the polygonal bars 23 to rotate. This, in turn, causes one of the rotating shafts 26 to drive one of the sprockets 24 to rotate, and then the second chain 25 drives another sprocket 24 to rotate. This causes another rotating shaft 26 to drive another polygonal bar 23 to rotate, thus... The first shaft 22 and the third sprocket 20 are rotated, and the fourth sprocket 20 is rotated through the first chain 21, which in turn drives the second connecting shaft 14 to rotate. The two connecting shafts 14 drive the two first bevel gears 15 to rotate, which in turn drive the two second bevel gears 16 to mesh and rotate, causing the two half gears 17 to rotate. This, in turn, drives the four racks 18 to mesh and move, causing the separation frame 4 to swing left and right, thereby improving the stone and soil separation effect of the screen 6. No manual turning is required, which improves the efficiency of the device. The separated soil will fall from the bottom of the separation frame 4 into the collection frame 7 for unified collection, while the stones will remain on the top of the screen 6. After the separation is completed, the stones will be processed uniformly.

[0030] During the rotation of the two polygonal bars 23, the two polygonal bars 23 will drive the two reciprocating screws 8 to rotate, thereby driving the two moving blocks 9 connected to the outer threads of the two reciprocating screws 8 to move back and forth, thereby driving the cleaning brush 10 between the two moving blocks 9 to move accordingly, thereby cleaning the screen 6, preventing the screen 6 from becoming clogged during the stone and soil separation process, which would reduce the separation efficiency and effectively improve the practicality of the device.

[0031] During the left and right movement of the separation frame 4, the two sides of the separation frame 4 will come into contact with the four rubber pads 30 respectively. Then, the movement of the separation frame 4 can be effectively buffered by the action of the damping rod 27 and the shock-absorbing spring 28.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
