Description
Technical Field
[0001] This utility model relates to the field of construction waste recycling technology, and more specifically, to a construction waste recycling screening device. Background Technology
[0002] Construction waste recycling refers to the process of processing and transforming construction waste into reusable building materials or resources. This process not only helps reduce environmental pollution but also conserves resources and promotes sustainable development. In common processing, construction waste is typically crushed into small pieces using a crusher, and then separated into materials of different particle sizes using a screening machine. However, some problems still exist in practical use. For example, some screening machines use vibrating filter plates to screen and separate materials; however, during material collection, when the collection bin is full, workers need to stop the machine, change the bin, and then restart the equipment to prevent material spillage during the bin-changing process. This operation not only reduces production efficiency but also the frequent start-ups and shutdowns can adversely affect the equipment. Utility Model Content
[0003] In order to overcome the above-mentioned defects of the prior art, the present invention provides a construction waste recycling and screening device to solve the problem that in the prior art, when the container is full during the material collection process, the machine needs to be stopped to replace the container, which leads to reduced production smoothness and frequent start-up and shutdown are detrimental to the equipment.
[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a construction waste recycling and screening device, comprising...
[0005] A base plate, on the top of which a screening box is fixedly installed, and inside the screening box are arranged a screen plate, a baffle, a material blocking component, and a collection box one in sequence. The outer surface of the end of the baffle is fixedly installed with the inner wall of the top of the screening box, and the outer edge of the collection box one is slidably installed with the inner wall of the bottom of the screening box. A vibration component is installed on the outside of the screen plate.
[0006] The material blocking assembly includes a hollow frame, a frame plate, and a slider. The top of the hollow frame is provided with several protruding posts, and the outer surfaces of the protruding posts are movably sleeved with the mesh gap of the screen plate. The frame plate is fixedly installed on the inner wall of the screening box. A lead screw is rotatably installed in the middle of the frame plate. A motor is fixedly installed at the bottom of the frame plate. The output end of the motor is fixedly sleeved with the bottom end of the lead screw. The inner surface of the slider is threadedly connected to the outer surface of the lead screw. The upper surface of the slider side is fixedly installed on the bottom of the hollow frame.
[0007] The material blocking assembly further includes an electric push rod and a push plate. The outer surface of the electric push rod is fixedly sleeved with the middle part of the screening box. The middle part of the push plate is fixedly installed with the side end of the electric push rod. The outer edges of both ends of the push plate are slidably installed with the inner surface of the screening box. The bottom of the push plate is slidably installed with the upper surface of the screen plate.
[0008] The vibration assembly includes an eccentric vibrator and springs. The bottom of the eccentric vibrator is fixedly installed on the upper surface of the base plate. The side end of the top of the eccentric vibrator is rotatably sleeved with the middle of the side edge of the sieve plate. Four springs are provided at the four corners of the bottom of the sieve plate.
[0009] The system also includes a support platform, a second collection box, and a cover assembly. The bottom of the support platform is fixedly installed on the upper surface of the base plate, the second collection box is placed on top of the support platform, and the cover assembly is located outside the discharge port of the screening box.
[0010] The cover assembly includes a column, an L-shaped plate, a cover plate, gears, and a second motor. The bottom of the column is fixedly installed on the upper surface of the discharge port of the screening box. The bottom of the L-shaped plate is fixedly sleeved on the outer surface of the shaft, and both ends of the shaft are rotatably sleeved with the inner wall of the top of the column. The middle part of the side edge of the cover plate is fixedly installed with the end of the L-shaped plate away from the column. There are two gears, one of which is fixedly sleeved with the end of the shaft, and the other is fixedly sleeved with the output end of the second motor. The two gears mesh with each other.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] In the above solution, by setting up a material blocking component, when changing the collection box 1 at the bottom of the screening box, the operator can control the motor 1 to start. The lead screw connected to the output end of the motor 1 rotates in the middle of the frame plate. The slider threaded on it drives the installed hollow frame and protrusions to move upward along the surface of the frame plate until the protrusions coincide with the gap of the screen plate mesh. At this time, the material put in from the top of the screening box is blocked at the top of the screen plate and will not fall downward. Therefore, when the operator pulls the collection box 1 filled with small particles out of the bottom of the screening box for replacement, the material will not continue to be thrown downward, thus avoiding the damage caused by frequent start-up and shutdown of the vibration component that drives the screen plate vibration.
[0013] In the above scheme, by setting up a cover assembly, when changing the second collection box, the operator can control the second motor to start, so that the gear connected to its output end rotates and drives another meshing gear to rotate. The shaft fixedly sleeved with the gear rotates along the inner wall of the column, causing the L-shaped plate fixed on it to deflect, so that the cover plate installed at the end of the L-shaped plate is rotated to fit against the discharge port of the screening box, thereby blocking the material inside.

[0021] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.
[0022] As attached Figure 1 To be continued Figure 5 An embodiment of this utility model provides a construction waste recycling and screening device, including...
[0023] The bottom plate 1 has a screening box 2 fixedly installed on the top of the bottom plate 1. Inside the screening box 2, there are screen plates 4, baffles 5, blocking components 6, and collection boxes 7 arranged in sequence. The outer surface of the end of the baffle 5 is fixedly installed with the inner wall of the top of the screening box 2. The outer edge of the collection box 7 is slidably installed with the inner wall of the bottom of the screening box 2. A vibration component 3 is installed on the outside of the screen plate 4.
[0024] The material blocking assembly 6 includes a hollow frame 60, a frame plate 62, and a slider 65. The top of the hollow frame 60 is provided with several protruding posts 61, and the outer surfaces of the protruding posts 61 are movably sleeved with the mesh gap of the screen plate 4. The frame plate 62 is fixedly installed on the inner wall of the screening box 2. A lead screw 64 is rotatably installed in the middle of the frame plate 62. A motor 63 is fixedly installed at the bottom of the frame plate 62. The output end of the motor 63 is fixedly sleeved with the bottom end of the lead screw 64. The inner surface of the slider 65 is threadedly connected to the outer surface of the lead screw 64. The upper surface of the side of the slider 65 is fixedly installed with the bottom of the hollow frame 60.
[0025] The material blocking assembly 6 also includes an electric push rod 66 and a push plate 67. The outer surface of the electric push rod 66 is fixedly sleeved with the middle part of the screening box 2. The middle part of the push plate 67 is fixedly installed with the side end of the electric push rod 66. The outer edges of both ends of the push plate 67 are slidably installed with the inner surface of the screening box 2. The bottom of the push plate 67 is slidably installed with the upper surface of the screen plate 4.
[0026] By setting up an electric push rod 66 and a pusher plate 67, after a single material screening is completed, before the next material feeding, the operator can control the electric push rod 66 to extend and push the bottom of the connected pusher plate 67 to move laterally along the upper surface of the screen plate 4 and with both ends attached to the inner walls of the screening box 2. This allows large particles of material at the top of the screen plate 4 to be discharged through the outlet of the screening box 2 into the inside of the collection box 2 9, thereby reducing the accumulation of large particles of material at the top of the screen plate 4 and causing mesh blockage, and improving the actual material screening efficiency.
[0027] The vibration assembly 3 includes an eccentric vibrator 30 and springs 31. The bottom of the eccentric vibrator 30 is fixedly installed on the upper surface of the base plate 1. The side end of the top of the eccentric vibrator 30 is rotatably sleeved with the middle of the side edge of the screen plate 4. Four springs 31 are provided at the four corners of the bottom of the screen plate 4.
[0028] It also includes a support platform 8, a second collection box 9, and a cover assembly 10. The bottom of the support platform 8 is fixedly installed on the upper surface of the base plate 1, the second collection box 9 is placed on top of the support platform 8, and the cover assembly 10 is set outside the discharge port of the screening box 2.
[0029] The cover assembly 10 includes a column 100, an L-shaped plate 101, a cover plate 102, a gear 103, and a motor 104. The bottom of the column 100 is fixedly installed on the upper surface of the discharge port of the screening box 2. The bottom of the L-shaped plate 101 is fixedly sleeved on the outer surface of the shaft, and the two ends of the shaft are rotatably sleeved with the inner wall of the top of the column 100. The middle part of the side edge of the cover plate 102 is fixedly installed with the end of the L-shaped plate 101 away from the column 100. There are two gears 103, one of which is fixedly sleeved with the end of the shaft, and the other is fixedly sleeved with the output end of the motor 104. The two gears 103 mesh with each other.
[0030] By setting up the cover assembly 10, when changing the collection box 2 9, the operator can control the motor 2 104 to start, so that the gear 103 connected to its output end rotates, and drives another meshing gear 103 to rotate. The shaft fixedly sleeved with the gear 103 rotates along the inner wall of the column 100, causing the L-shaped plate 101 fixed on it to deflect, so that the cover plate 102 installed at the end of the L-shaped plate 101 is rotated to fit against the discharge port of the screening box 2, thereby blocking the material in it.
[0031] The working process of this utility model is as follows:
[0032] When replacing the collection box 7 at the bottom of the screening box 2, the operator can start the motor 63. The lead screw 64 connected to the output end of the motor 63 rotates in the middle of the frame plate 62. The slider 65 threaded on it drives the installed hollow frame 60 and protrusion 61 to move upward along the surface of the frame plate 62 until the protrusion 61 coincides with the mesh gap of the screen plate 4. At this time, the material put into the top of the screening box 2 is blocked at the top of the screen plate 4 and will not fall downward. Therefore, when the operator pulls the collection box 7 filled with small particles out of the bottom of the screening box 2 for replacement, the material will not continue to be thrown downward, thus avoiding the damage caused by the frequent start-up and shutdown of the vibration component 3 that drives the vibration of the screen plate 4.
