Description

Technical Field

[0001] This application relates to the field of concrete recycling, and more specifically, to a device for recycling concrete construction waste. Background Technology

[0002] Concrete construction waste recycling equipment is a device that uses mechanical crushing, screening, and washing processes to convert waste concrete generated during construction into recycled aggregates. This can reduce waste landfill, dust and sewage pollution, and recycled aggregates can replace natural sand and gravel, saving resources and reducing waste disposal costs. Some recycled materials can also be sold.

[0003] In existing concrete construction waste recycling devices, the screening device is a key link in ensuring the quality of recycled aggregates. The material jumps forward by vibrating the screen, and particles smaller than the screen hole size fall down while larger ones remain on the screen surface, thus screening the particles after the concrete is crushed.

[0004] However, the existing screening devices still have the following shortcomings in use: after the concrete particles are screened by the vibrating screen, the larger particles left on the screen surface still need to be manually removed from the screen before the material can be added to the screen and the vibrating screen can continue to screen. Manually removing the particles from the screen is time-consuming and labor-intensive. Utility Model Content

[0005] To overcome the above shortcomings, this application provides a concrete construction waste recycling device, which aims to improve the problem of requiring manual handling to remove particles from the screen before adding material to the screen and continuing to vibrate the screen for screening.

[0006] This application provides a concrete construction waste recycling device, including a workbench, a screen for screening crushed concrete particles above the workbench, a prying mechanism for driving the screen to vibrate above the workbench, and a material feeding mechanism for feeding material above the workbench.

[0007] The actuating mechanism includes a top plate, which is positioned above the workbench. A rotating shaft is rotatably connected to the inner side of the top plate. A screen is connected to the outer surface of the rotating shaft. A U-shaped plate is connected to the top of the screen. A baffle is rotatably connected to one end of the U-shaped plate via a hinge. A counterweight is connected to the bottom of the baffle.

[0008] In one specific implementation, a mounting bracket is connected to the top of the top plate, a motor is connected to the bottom of the mounting bracket, and a rotating plate is connected to the output shaft of the motor.

[0009] In the above implementation process, by setting up a motor, the rotating plate can be driven to rotate by controlling the motor, and the rotation of the rotating plate can drive one side of the screen to move up and down.

[0010] In one specific implementation, the outer surface of the rotating plate is connected to multiple sets of actuating elements, the outer surface of the rotating plate is provided with a notch, and the outer surface of the rotating plate is connected to a triangular element.

[0011] In the above implementation process, by setting up the actuating component, the rotation of the rotating plate can drive the actuating component to rotate, thereby driving one side of the screen to move up and down.

[0012] In one specific implementation, a horizontal plate is connected to one side of the screen, and a protrusion is connected to the bottom of the horizontal plate. The protrusion is movably inserted between two sets of actuating parts.

[0013] In the above implementation process, by setting the protrusion, the protrusion can be inserted between two sets of actuating parts. By rotating the actuating parts, the protrusion is squeezed, causing the protrusion to move up and down, which in turn drives the horizontal plate to move up and down, and drives one side of the screen to move up and down.

[0014] In one specific implementation, the bump has inclined surfaces on both sides to facilitate its movement.

[0015] In the above implementation process, by setting the inclined surface, it is easier for the actuating component to squeeze the two sides of the protrusion, and the actuating component squeezing the inclined surface makes it easier for the protrusion to move up and down.

[0016] In one specific implementation, the crossbar cannot pass between the two sets of actuating elements, and the crossbar can move up and down at the notch.

[0017] In the above implementation process, since the horizontal plate cannot pass between the two sets of actuating parts, the horizontal plate is always positioned above the actuating parts when the protrusion has not moved to the notch.

[0018] In one specific implementation, the bottom of the top plate is connected to a discharge pipe, which is connected to the top of the workbench. The discharge pipe is internally connected to multiple sets of first springs, the other end of which is connected to the bottom of the screen.

[0019] In the above implementation process, by setting up the discharge pipe, the concrete particles passing through the screen can be output through the discharge pipe. When the screen is in a horizontal state, the first spring is already in a certain tension state. When the protrusion moves to the notch, the first spring will release elastic potential energy to contract, causing one side of the screen connecting the horizontal plate to tilt downward.

[0020] In one specific implementation, the feeding mechanism includes a collection box connected to the top of the workbench, and a feeding port is provided on one side of the collection box.

[0021] In the above implementation process, by setting the feed inlet, when one side of the screen connecting plate is tilted downward, concrete particles that have not passed through the screen will enter the inside of the collection box through the feed inlet.

[0022] In one specific implementation, the inside of the collection box is provided with a sloping surface to facilitate the movement of concrete particles.

[0023] In the above implementation process, by setting the slope surface, the concrete particles collected inside the collection box can move towards the direction of the lower slope surface and be discharged from the collection box later.

[0024] In one specific implementation, a fixing plate is fixedly connected to one side of the collection box, the fixing plate has a cavity inside, a telescopic plate is slidably connected to the inner wall of the cavity, one end of the telescopic plate is connected to multiple sets of second springs, the other end of the second springs is connected to the inner wall of the cavity, and a lever is connected to one side of the telescopic plate.

[0025] In the above implementation process, by setting the toggle block, the telescopic plate can be moved by moving the toggle block, which compresses the second spring, opens an outlet in the collection box, and discharges the concrete particles inside the collection box.

[0026] Compared with the prior art, the beneficial effects of this application are as follows: By setting the actuation mechanism, the rotation of the rotating plate can drive the screen to move up and down, thereby achieving a vibration effect. After the screen vibrates for a certain period of time, the protrusion will move to the notch, causing one side of the screen to tilt downwards, and the concrete particles above the screen will be transported to the inside of the collection box through the discharge port. This solves the problem of having to manually remove the particles from the screen before adding material to the screen and continuing to vibrate the screen for screening.

[0037] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0038] Please see Figure 1 This application provides a concrete construction waste recycling device, including a workbench 1.

[0039] Please see Figure 1 Above the workbench 1 is a screen 4 for screening the crushed concrete particles, above the workbench 1 is a prying mechanism 2 for driving the screen 4 to vibrate, and above the workbench 1 is a feeding mechanism 3 for feeding materials.

[0040] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 The actuating mechanism 2 includes a top plate 2015, which is located above the workbench 1. A rotating shaft 204 is rotatably connected to the inner side of the top plate 2015. A screen 4 is connected to the outer surface of the rotating shaft 204. A U-shaped plate 5 is connected to the top of the screen 4. A baffle 2014 is rotatably connected to one end of the U-shaped plate 5 via a hinge 205. A counterweight 207 is connected to the bottom of the baffle 2014.

[0041] In the specific setup, the top of the top plate 2015 is connected to the mounting bracket 201, the bottom of the mounting bracket 201 is connected to the motor 202, and the output shaft of the motor 202 is connected to the rotating plate 203. The motor 202 can be controlled to drive the rotating plate 203 to rotate, and the rotation of the rotating plate 203 can drive one side of the screen 4 to move up and down.

[0042] In a specific configuration, the outer surface of the rotating plate 203 is connected to multiple sets of actuating elements 2011. The outer surface of the rotating plate 203 is provided with a notch 2012 and a triangular element 2013 is connected to the outer surface of the rotating plate 203. The actuating elements 2011 can be rotated by the rotation of the rotating plate 203, thereby causing one side of the screen 4 to move up and down.

[0043] A horizontal plate 206 is connected to one side of the screen 4, and a protrusion 208 is connected to the bottom of the horizontal plate 206. The protrusion 208 is movably inserted between two sets of actuating members 2011. The protrusion 208 can be inserted between the two sets of actuating members 2011. By rotating the actuating members 2011, the protrusion 208 is squeezed, causing the protrusion 208 to move up and down, which in turn drives the horizontal plate 206 to move up and down, and thus drives one side of the screen 4 to move up and down.

[0044] In a specific configuration, both sides of the protrusion 208 are provided with inclined surfaces 209 to facilitate the movement of the protrusion 208. The inclined surfaces 209 facilitate the pressing of the sides of the protrusion 208 by the actuating member 2011, and the pressing of the inclined surfaces 209 by the actuating member 2011 makes it easier for the protrusion 208 to move up and down.

[0045] In a specific configuration, the horizontal plate 206 cannot pass between the two sets of actuating members 2011. The horizontal plate 206 can move up and down at the notch 2012. Since the horizontal plate 206 cannot pass between the two sets of actuating members 2011, the horizontal plate 206 is always positioned above the actuating member 2011 when the protrusion 208 is not moved to the notch 2012.

[0046] In the specific setup, the bottom of the top plate 2015 is connected to the discharge pipe 6, which is connected to the top of the workbench 1. The discharge pipe 6 is connected to multiple sets of first springs 2010 inside, and the other end of the first spring 2010 is connected to the bottom of the screen 4. The discharge pipe 6 allows concrete particles passing through the screen 4 to be output through the discharge pipe 6. When the screen 4 is in a horizontal state, the first spring 2010 is already in a certain stretched state. When the protrusion 208 moves to the notch 2012, the first spring 2010 will release its elastic potential energy and contract, causing the side of the screen 4 connected to the horizontal plate 206 to tilt downward.

[0047] In a specific configuration, the material feeding mechanism 3 includes a collection box 301, which is connected to the top of the workbench 1. A feed inlet 308 is provided on one side of the collection box 301. With the feed inlet 308, when the side of the screen 4 connected to the horizontal plate 206 is tilted downward, concrete particles that have not passed through the screen 4 will enter the interior of the collection box 301 through the feed inlet 308.

[0048] In the specific configuration, the inside of the collection box 301 is provided with a slope surface 302 to facilitate the movement of concrete particles. The slope surface 302 allows the concrete particles collected inside the collection box 301 to move towards the lower slope surface 302 and be discharged from the collection box 301 later.

[0049] In the specific setup, a fixing plate 303 is fixedly connected to one side of the collection box 301. A cavity 304 is opened inside the fixing plate 303. A telescopic plate 306 is slidably connected to the inner wall of the cavity 304. Multiple sets of second springs 305 are connected to one end of the telescopic plate 306. The other end of the second springs 305 is connected to the inner wall of the cavity 304. A lever 307 is connected to one side of the telescopic plate 306. By setting the lever 307, the telescopic plate 306 can be moved by moving the lever 307, which compresses the second springs 305, opens an outlet in the collection box 301, and discharges the concrete particles inside the collection box 301.

[0050] The working principle of this concrete construction waste recycling device is as follows: When using the device, concrete particles to be screened are added above the screen 4. The motor 202 drives the rotating plate 203 to rotate, which in turn drives the actuating element 2011. The rotation of the actuating element 2011 squeezes the protrusion 208, causing it to move up and down. This movement drives the horizontal plate 206 up and down, and consequently, one side of the screen 4. When the protrusion 208 is not at the notch 2012, the horizontal plate 206 remains above the actuating element 2011. The up-and-down movement of the protrusion 208, combined with the first spring 2010, creates a vibration effect. When the screen 4 is in a horizontal state, the first... Spring 2010 is already under a certain tension. When protrusion 208 moves to notch 2012, spring 2010 will release elastic potential energy and contract, causing one side of the screen 4 connected to the horizontal plate 206 to tilt downward. After the screen 4 tilts, baffle 2014 is still in a vertical downward state under the action of counterweight. A gap will be generated between baffle 2014 and U-shaped plate 5. Concrete particles that do not pass through screen 4 will enter the inside of collection box 301 through feed inlet 308. By moving the toggle block 307, the telescopic plate 306 is moved, compressing the second spring 305, opening an outlet in collection box 301, and discharging the concrete particles inside collection box 301.

[0051] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
