Description

Technical Field

[0001] This utility model relates to the field of civil engineering, specifically a civil engineering vibrating screen. Background Technology

[0002] The types of civil engineering materials are diverse, and large particles in the screen box need to be cleaned regularly to prevent blockage. The vibrating screen needs to be designed with a convenient cleaning structure to achieve quick disassembly and installation, reduce manual intervention, and lower maintenance costs.

[0003] Currently, the screen box of vibrating screens is usually a closed or semi-closed structure, and manual cleaning is required to remove the remaining granular material, which is complicated and time-consuming. Utility Model Content

[0004] To overcome the above-mentioned shortcomings, this utility model provides a civil engineering vibrating screen.

[0005] The technical solution adopted by this utility model is as follows:

[0006] A vibrating screen for civil engineering includes a belt conveyor with a hopper at its top and a support frame on its outer side. The hopper is fixedly connected to the top of the support frame. A transverse moving mechanism is located above the belt conveyor and below the hopper. The transverse moving mechanism includes a moving frame with a screen box inside. Slide rails are fixedly connected to the top left and right sides of the moving frame. Support plates are fixedly connected to the middle of the left and right side walls of the screen box, above the slide rails. Sliding blocks are fixedly connected to the front and rear ends of the bottom of the support plates, slidingly engaging with the slide rails. A reciprocating drive mechanism is provided at the front of the screen box. The top and bottom of the screen box are open. The screen box has fixing holes on the bottom of the left and right side walls and the front and back sides. The bottom of the inner side of the screen box has a movable frame. The outer wall of the movable frame slides with the inner wall of the screen box. The screen is fixedly connected to the inner wall of the movable frame. The left and right side walls and the front and back sides of the movable frame have insertion holes, which correspond to the fixing holes. The inner side of the rear insertion hole and the rear fixing hole are slidably inserted into the fixing shaft. Both ends of the fixing shaft pass through the outer side of the fixing hole. Nut 1 is threaded onto the outer wall of both ends of the fixing shaft. The inner side of the front insertion hole and the front fixing hole are slidably inserted into the pin. The left end of the pin passes through the outer side of the fixing hole. Nut 2 is threaded onto the outer wall of the left end of the pin. The outer wall of nut 2 is pressed against the outer wall of the screen box. The right end of the pin is a handle.

[0007] The lateral movement mechanism includes a lateral frame, the front half of which protrudes from the front of the belt conveyor. Support legs are fixedly connected to the four bottom corners of the lateral frame. Slide rails are fixedly connected to the top left and right sides of the lateral frame. The moving frame is located between the tops of the two slide rails. Slider 1 is fixedly connected to the front and rear ends of the bottom left and right sides of the moving frame. Slider 1 is slidably engaged with slide rail 1. An electric push rod is fixedly installed on the top rear side of the lateral frame. The front end of the electric push rod is fixedly connected to the middle of the rear end of the moving frame.

[0008] The reciprocating drive mechanism includes a mounting frame, which is angle iron in shape. The bottom of the mounting frame is horizontal, and the right side of the mounting frame is vertical. The bottom of the mounting frame is fixedly connected to the top front side of the moving frame. A connecting column one is fixedly connected to the front side of the right side wall of the screen box. The connecting column one is located above the support plate. A motor is fixedly installed at the bottom upper part of the mounting frame. The output shaft of the motor passes through the right side of the mounting frame and is rotatably connected to the right side of the mounting frame. A flywheel is fixedly sleeved on the outer wall of the right end of the motor's output shaft. A connecting column two is fixedly connected to the outer side of the right side wall of the flywheel. There is a connecting rod between the connecting column one and the connecting column two. The two ends of the connecting rod are rotatably connected to the connecting column one and the connecting column two, respectively.

[0009] The left and right ends of the active frame are rounded.

[0010] The beneficial effects of this utility model are:

[0011] This invention uses a motor to drive a flywheel to rotate, and a connecting rod to move the screen box back and forth. This movement allows the material to tumble and bounce fully inside the screen box, increasing the contact frequency and area between the material and the screen, thereby effectively improving screening efficiency and quality, ensuring that small particles can pass through the screen and large particles remain inside the screen box.

[0012] When large particles need to be cleaned from the screen box, the electric push rod can easily push the screen box forward to the front of the belt conveyor, making it convenient for operators to carry out cleaning operations. At the same time, the movable frame is connected to the screen box through the fixed shaft and the pin, making disassembly and installation very simple. Just pull out or insert the pin and tighten or loosen the nut, which greatly shortens the cleaning time and improves work efficiency. Attached Figure Description

Fixing holes 18 are provided on the front and rear sides of the bottom of the wall. The inner bottom of the screen box 8 has a movable frame 19. The outer wall of the movable frame 19 slides with the inner wall of the screen box 8. The screen 20 is fixedly connected to the inner wall of the movable frame 19. Insertion holes 21 are provided on the front and rear sides of the left and right side walls of the movable frame 19. The insertion holes 21 correspond to the fixing holes 18. The inner side of the rear insertion hole 21 and the rear fixing hole 18 is slidably inserted into the fixing shaft 22. Both ends of the fixing shaft 22 pass through the outer side of the fixing hole 18. Nut 23 is threaded onto the outer wall of both ends of the fixing shaft 22. Pin 24 is slidably inserted into the inner side of the front insertion hole 21 and the front fixing hole 18. The left end of the pin 24 passes through the outer side of the fixing hole 18. Nut 25 is threaded onto the outer wall of the left end of the pin 24. The outer wall of nut 25 abuts against the outer wall of the screen box 8. The right end of the pin 24 is a handle.

[0022] The lateral movement mechanism includes a lateral frame 2, the front half of which protrudes from the front of the belt conveyor 1. Support legs 3 are fixedly connected to the four bottom corners of the lateral frame 2. Slide rails 4 are fixedly connected to the top left and right sides of the lateral frame 2. The moving frame 5 is located between the tops of the two slide rails 4. Slider 6 is fixedly connected to the front and rear ends of the bottom left and right sides of the moving frame 5. Slider 6 is slidably engaged with slide rails 4. An electric push rod 7 is fixedly installed on the top rear side of the lateral frame 2. The front end of the push rod of the electric push rod 7 is fixedly connected to the middle of the rear end of the moving frame 5.

[0023] The reciprocating drive mechanism includes a mounting frame 13, which is in the shape of an angle iron. The bottom of the mounting frame 13 is horizontal, and the right side of the mounting frame 13 is vertical. The bottom of the mounting frame 13 is fixedly connected to the top front side of the movable frame 5. The front side of the right side wall of the screen box 8 is fixedly connected to the connecting column 12, which is located above the support plate 10. The motor 14 is fixedly mounted on the upper bottom of the mounting frame 13. The output shaft of the motor 14 passes through the right side of the mounting frame 13 and is rotatably connected to the right side of the mounting frame 13. The outer wall of the right end of the output shaft of the motor 14 is fixedly sleeved with a flywheel 15. The outer side of the right side wall of the flywheel 15 is fixedly connected to the connecting column 16. There is a connecting rod 17 between the connecting column 12 and the connecting column 16. The two ends of the connecting rod 17 are rotatably connected to the connecting column 12 and the connecting column 16, respectively.

[0024] The left and right ends of the active frame (19) are arc-shaped.

[0025] The material falls from the bottom of the feed hopper 27 into the screen box 8 located below it.

[0026] When motor 14 starts, its output shaft drives flywheel 15 to rotate. Since connecting column 2 16 is fixedly connected to the outer side of the right side wall of flywheel 15, and connecting column 2 16 is rotatably connected to one end of connecting rod 17, and the other end of connecting rod 17 is rotatably connected to connecting column 12 on the front side of the right side wall of screen box 8, when flywheel 15 rotates, it drives screen box 8 to move back and forth along slide rail 2 9 in moving frame 5 through the transmission action of connecting rod 17, and screens the material in screen box 8. During this process, small particles fall through screen 20 onto belt conveyor 1 below and are transported to the designated position by belt conveyor 1, while large particles remain in screen box 8.

[0027] When a certain amount of large particles that need to be cleaned accumulate in the screen box 8, the push rod of the electric push rod 7 extends forward, pushing the moving frame 5 to slide forward on the slide rail 4 of the transverse frame 2, thereby driving the entire transverse moving mechanism and the screen box 8 to move forward, so that the screen box 8 is in front of the belt conveyor 1.

[0028] Then pull out the pin 24 in the front insertion hole 21 and the fixing hole 18 to release the fixing of the front of the movable frame 19. At this time, the movable frame 19 can rotate downward with the fixing shaft 22 as the center, thereby opening the bottom of the screen box 8 and emptying the large particles in the screen box 8.

[0029] After the large particles are cleaned, the movable frame 19 is reset, the pin 24 is reinserted and fixed with nut 25, the electric push rod 7 retracts, and the screen box 8 returns to the initial position to continue the material screening work.

[0030] The belt conveyor 1 in this utility model is an existing technology device, and its structure will not be described in detail. This utility model only protects the mechanical part, and the functions implemented by the software control part are not within the scope of protection of this utility model.
