[0001] This utility model relates to the field of earthwork slag removal technology, and in particular to an earthwork slag removal device that is easy to clean. Background Technology

[0002] Earthwork engineering includes site leveling, excavation of foundation pits and trenches, roadbed excavation and filling, civil defense engineering excavation, ground filling and foundation pit backfilling, etc. The soil produced during the excavation process is usually mixed with a large amount of stone particles. In order to improve soil utilization and ensure project quality, the stone debris in the soil needs to be cleaned and treated.

[0003] A search revealed that patent CN222969897U discloses a slag removal device for easy cleaning of earthwork. It is equipped with a crushing component. When the servo motor on the U-shaped frame is started, it works with the drive gear and driven gear to rotate the crushing roller, thereby crushing the material. At the same time, the round rod, inclined plate, hinge seat and servo hydraulic rod can receive the crushed material to avoid damage to subsequent parts. With the help of the screen plate and discharge port, it can be easily screened.

[0004] However, the above-mentioned device has the following drawbacks: Although the device can crush and screen materials, the two bottom screen plates work simultaneously. When screening materials and the screen plates become clogged and need cleaning, the entire device must be stopped and the internal screen plates opened to clean them. This not only affects work efficiency but also makes it inconvenient to disassemble and clean the screen plates. Therefore, further improvements are needed. To this end, we propose an easy-to-clean earthwork slag removal device. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1-3 As shown, a slag removal device for easy cleaning of earth and rock excavation includes a base plate 1. Multiple support rods 2 are fixed on the upper surface of the base plate 1. The tops of the multiple support rods 2 are fixedly connected to a box body 3. Two symmetrical discharge ports 31 are opened on both sides of the bottom of the box body 3. A hopper 4 is fixed on the top of the box body 3. A crushing component is set on the top of the box body 3 and below the hopper 4. A central shaft 8 is rotatably connected inside the box body 3 and below the crushing component. An adjusting plate 9 is fixed on the surface of the central shaft 8. A second motor 10 is fixed on the outer wall of the box body 3. The output end of the central shaft 8 is fixedly connected to the output end of the second motor 10. Screening components 11 are horizontally arranged inside the two discharge ports 31. Side openings 32 are opened on both sides of the box body 3 near the screening components 11. A controller is installed on the outer wall of the box body 3.

[0022] In this embodiment, the controller uses a Siemens SIMATIC S7-1500 series CPU 1516-3PN / DP (6ES7516-3AN00-0AB0) to control the operation of the second motor 10.

[0023] The crushing assembly includes two horizontal shafts 5 that are rotatably connected to the housing 3 via bearings. Each horizontal shaft 5 has a pressing roller 6 fixed on its surface. Each horizontal shaft 5 has a gear fixed at one end outside the housing 3, and the two gears mesh with each other. A first motor 7 is fixed to the outer wall of the housing 3, and any horizontal shaft 5 is fixedly connected to the output end of the first motor 7.

[0024] In this embodiment, the first motor 7 is controlled by a controller. After the first motor 7 drives the horizontal shaft 5 corresponding to its output end to rotate, the gears on the two horizontal shafts 5 mesh with each other, and the other horizontal shaft 5 will also rotate, thereby driving the two extrusion rollers 6 to rotate. When material passes between the two extrusion rollers 6, the two extrusion rollers 6 are used to crush the material.

[0025] Two guide plates 15 are fixed at the top of the inside of the box 3.

[0026] After the material is fed from the hopper 4 into the box 3, the material can slide down along the surface of the two guide plates 15 into the space between the two extrusion rollers 6.

[0027] Both sides of the inner wall of the housing 3 are fixed with horizontal plates 13, and a contact switch 14 is fixed on the lower surface of the horizontal plate 13. The contact switch 14 and the second motor 10 are both electrically connected to the controller.

[0028] By controlling the second motor 10 to drive the central shaft 8 to rotate, the tilt direction of the adjusting plate 9 can be changed, allowing the crushed material to slide down the adjusting plate 9 onto the surface of the corresponding screening component 11 below for screening. Therefore, the two screening components 11 below can be used alternately, and when one is in use, the other screening component 11 can be disassembled for cleaning. Furthermore, each time the adjusting plate 9 is rotated, after the top of the adjusting plate 9 contacts the contact switch 14, the controller controls the second motor 10 to stop rotating, and the contact switch 14 acts as a limit switch.

[0029] The screening component 11 includes a frame plate 111, and a screen 112 is fixedly installed inside the frame plate 111.

[0030] When material falls onto the surface of screen 112, screen 112 can be used to screen the material.

[0031] One end of the frame plate 111 passes through the side opening 32 and is fixedly connected to the end plate 113. The bottom end of the end plate 113 has a mounting hole. A screw 12 is fixed on the outer side wall of the box body 3 near the mounting hole. The screw 12 passes through the mounting hole and is threaded with a nut.

[0032] The screw 12 and nut securely install the end plate 113. When disassembling, the nut is unscrewed from the surface of the screw 12, and the frame plate 111 can be pulled out from the side opening 32, making the disassembly and installation of the screening component 11 simpler and more convenient.

[0033] Working principle: First, start the first motor 7 to drive the two extrusion rollers 6 to rotate. Then, feed the material from the hopper 4. After being guided by the two guide plates 15, the material falls between the two extrusion rollers 6 and is crushed. The crushed material falls along the adjusting plate 9 onto the surface of the screen 112 of one of the screening components 11. The material is screened by the screen 112. If it is necessary to clean the screen 112, control the second motor 10 to drive the central shaft 8 and the adjusting plate 9 to rotate. Use the adjusting plate 9 to guide the material to the screening component 11 on the other side, so that the unused screening component 11 can be disassembled and cleaned.

[0034] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it.
