Description

Technical Field

[0001] The present application relates to the technical field of solid waste treatment and recycling, and particularly to a road solid waste treatment and recycling device. Background Art

[0002] During the process of excavating and turning over the abandoned old asphalt pavement, road solid waste will be generated. After being recycled, the road solid waste can be reused again. Among them, the crushing of waste asphalt is an important step in the road solid waste recycling process.

[0003] The existing crushing equipment includes a box body, a crushing component arranged in the box body, and a feeding plate. An inlet groove is formed on the top surface of the box body. The feeding plate is inclined and the bottom end is located directly above the inlet groove. The conveyor belt conveys the asphalt fragments to the feeding plate. Since the feeding plate is inclined, the asphalt fragments slide downward from the feeding plate and are conveyed to the crushing component through the inlet groove, which is convenient for crushing the asphalt fragments.

[0004] During the crushing process of the above-mentioned asphalt fragments, since the asphalt fragments are randomly distributed on the conveyor belt, the number of asphalt fragments crushed by the crushing component each time is different. As a result, the crushing rollers of the crushing component will run idly or overload, leading to low efficiency of solid waste recycling. Summary of the Invention

[0005] In order to improve the efficiency of solid waste recycling, the present application provides a road solid waste treatment and recycling device.

[0006] The road solid waste treatment and recycling device provided by the present application adopts the following technical solutions: A road solid waste treatment and recycling device includes a box body, a crushing component arranged in the box body. An inlet is arranged on the top surface of the box body. The device further includes: A feeding hopper, vertically arranged directly above the inlet. The bottom of the feeding hopper is tapered from top to bottom. The feeding hopper is fixedly connected to the box body; A feeding plate, inclined and arranged in the feeding hopper. The top of the feeding plate is fixedly connected to the feeding hopper. A distance for the asphalt fragments to flow through is left between the bottom end of the feeding plate and the side wall of the feeding hopper. The feeding plate is used for transporting the asphalt fragments; A metering component, including a metering rod, a first metering piece and a second metering piece. The metering rod is of a telescopic rod structure and is vertically arranged below the feeding plate. The top end of the metering rod is fixedly connected to the feeding plate; the first metering piece is located below the metering rod and is fixedly connected to the bottom end of the metering rod; the second metering piece is located below the first metering piece and is fixedly connected to the feeding hopper. There is a repulsive force between the second metering piece and the first metering piece; A closing component, arranged on the feeding hopper and used for closing the space between the bottom end of the feeding plate and the side wall of the feeding hopper; A connecting component, which is arranged at the bottom of the feed hopper and is used to control the connection state between the discharge part at the bottom end of the feed hopper and the outside; A transmission component, which is arranged on the feed hopper and includes a first transmission part and a second transmission part. The first transmission part adjusts the working state of the closing component based on the extension length of the metering rod; the second transmission part adjusts the working state of the connecting component based on the working state of the closing component.

[0007] By adopting the above technical solution, the asphalt fragments are conveyed to the feed plate by the conveyor belt and slide obliquely downward on the feed plate by relying on their own gravity. The asphalt fragments fall to the bottom of the feed hopper through the space reserved between the bottom end of the feed plate and the side wall of the feed hopper; Since the bottom of the feed hopper is isolated from the outside, the asphalt fragments at the bottom of the feed hopper gradually increase. During the process of the increase of the asphalt fragments, the asphalt fragments will gradually accumulate between the first metering piece and the second metering piece, so that the repulsive force between the first metering piece and the second metering piece gradually decreases, and then the piston of the metering rod gradually moves downward by relying on its own gravity; When the piston of the metering rod moves downward to a preset range, the first transmission part drives the closing component to close the space between the bottom end of the feed plate and the side wall of the feed hopper, so that the asphalt fragments on the feed plate cannot enter below the feed hopper; After the closing component is adjusted, the second transmission part adjusts the working state of the connecting component to connect the bottom of the feed hopper with the outside, so that the asphalt fragments at the bottom of the feed hopper enter the crushing component in the box through the feed port, thereby realizing the quantitative crushing of the asphalt fragments, avoiding the idling state of the crushing component, enabling the crushing component to effectively carry out the crushing work, and thus improving the efficiency of solid waste recycling.

[0008] Optionally, the closing component includes a closing telescopic plate and a closing spring. Among them, the closing telescopic plate is horizontally arranged below the feed plate. The fixed end of the closing telescopic plate is fixedly connected to the feed plate, and the movable end of the closing telescopic plate is used to abut against the side wall of the feed hopper; the closing spring is arranged inside the closing telescopic plate and is used to drive the closing telescopic plate to contract.

[0009] Optionally, the connecting component includes a connecting piece and a connecting spring. Among them, the connecting piece is a telescopic plate structure. The connecting piece is horizontally arranged. The fixed end of the connecting piece is fixedly connected to the outer wall of the feed hopper. The movable end of the connecting piece is inserted into the side wall of the feed hopper and is used to abut against the inner wall of the feed hopper; the connecting spring is arranged inside the connecting piece and is used to drive the connecting piece to extend.

[0010] Optionally, the first transmission part includes a transmission box, a first slider, and a first connecting pipe. The transmission box is horizontally arranged on one side of the metering rod and fixedly connected to the fixed end of the metering rod. The first slider is slidably arranged in the transmission box along the length direction of the transmission box. The first slider divides the interior of the transmission box into a water-free area and a water storage area in sequence along the direction away from the metering rod. There is a fluid preset in the water storage area. There is a mutual repulsive force between the first slider and the piston of the metering rod. When the first slider and the piston of the metering rod are within a preset range, the first slider can be driven to move by the piston of the metering rod. One end of the first connecting pipe is communicated with the water storage area, and the other end is communicated with the plate-free cavity of the closed expansion plate. Fluids are preset in the first connecting pipe, the water storage area, and the plate-free cavity of the closed expansion plate.

[0011] Optionally, the second transmission part includes a second slider and a second connecting pipe. The second slider is slidably arranged in the water storage area. The sliding direction of the second slider is the same as that of the first slider. The second slider divides the water storage area into a first transmission water storage area and a second transmission water storage area in sequence along the direction away from the first slider. Among them, the first connecting pipe is communicated with the first transmission water storage area. One end of the second connecting pipe is communicated with the second transmission water storage area, and the other end is communicated with the plate cavity of the connecting part. Fluids are preset in the second connecting pipe and the plate cavity of the connecting part.

[0012] Optionally, the elastic force of the connecting spring is always greater than the elastic force of the closed spring.

[0013] By adopting the above technical solution, when the piston of the metering rod moves downward to a preset range, due to the large mutual repulsive force between the piston of the metering rod and the first slider, the first slider slides in the direction away from the metering rod, and further the first slider squeezes the fluid in the first transmission water storage area into the plate-free cavity of the closed expansion plate through the first connecting pipe, so that the closed expansion plate extends, and further the closed expansion plate closes the space between the bottom end of the feeding plate and the side wall of the feeding hopper. Then, the first slider continues to move away from the metering rod under the drive of the piston of the metering rod, so that the first slider squeezes the second slider through the fluid in the first transmission water storage area, and the second slider and the first slider move away from the metering rod together. During the sliding process of the second slider, the second slider squeezes the fluid in the second transmission water storage area into the plate cavity of the connecting part through the second connecting pipe, so that the connecting part contracts, and further the asphalt fragments at the bottom of the feeding hopper can be quantitatively dropped onto the crushing assembly.

[0014] Optionally, when the piston of the metering rod and the first slider are within a preset range, there is a one-way damping effect between the piston of the metering rod and the fixed end of the metering rod.

[0015] By adopting the above technical solution, during the process of discharging the asphalt fragments at the bottom of the feed hopper, as the asphalt fragments between the first measuring piece and the second measuring piece gradually decrease, the repulsive force between the first measuring piece and the second measuring piece gradually increases, causing the first measuring piece and the piston of the measuring rod to move upward; When the piston of the measuring rod and the first slider are within a preset range and the piston of the measuring rod moves upward, the piston of the measuring rod is subjected to a damping effect, which prolongs the time for the piston of the measuring rod to move upward out of the preset range, facilitating the discharge of the fragments at the bottom of the feed hopper.

[0016] Optionally, during the synchronous movement of the first slider and the second slider, the first slider is used to block the connection between the first connecting pipe and the transmission box.

[0017] By adopting the above technical solution, after all the asphalt fragments at the bottom of the feed hopper are discharged, the distance between the upward moving piston of the measuring rod and the first slider exceeds the preset range, causing the connecting spring to drive the connecting piece to extend; During the extension process of the connecting piece, the plate chamber of the connecting piece gradually decreases, causing the fluid in the plate chamber of the connecting piece to enter the second transmission water storage area through the second connecting pipe, and then causing the second slider to slide towards the measuring rod; during the process of the second slider approaching the measuring rod, the second slider pushes the first slider through the fluid in the first transmission water storage area, causing the first slider and the second slider to approach the measuring rod synchronously; When the connecting piece extends and resets, the second slider synchronously resets, and due to the sliding stroke limit provided in the transmission box, the second slider will not further approach the measuring rod after resetting; when the second slider resets, the first slider continues to approach the measuring rod by its own inertia, causing the first connecting pipe and the first transmission water storage area to resume the connected state, and then enabling the closed telescopic plate to complete the reset under the action of the closing spring.

[0018] Optionally, the cross-section of the discharge part at the bottom end of the feed hopper is the same as the cross-section of the feed inlet.

[0019] In summary, the present application includes at least one of the following beneficial technical effects: By setting up a measuring component, a closing component, a connecting component and a transmission component, the measuring component monitors the amount of asphalt fragments at the bottom of the feed hopper. When the amount of asphalt fragments reaches the preset range, the transmission component drives the closing component to start, stopping the feeding at the bottom of the feed hopper. Then, the transmission component drives the adjustment of the state of the connecting component, making the bottom of the feed hopper communicate with the outside, so that the asphalt fragments can be quantitatively transported to the crushing component, avoiding the idling state of the crushing component, thereby improving the efficiency of solid waste recycling.

Detailed implementation manners

[0022] The following further elaborates on the present application in conjunction with the attached Figures 1-4 drawings.

[0023] An embodiment of the present application discloses a road solid waste treatment and recycling device. Referring to Figures 1 to 4 , a road solid waste treatment and recycling device includes a box body 1, a crushing assembly 2, a feed hopper 3, a feed plate 4, a metering assembly 5, a sealing assembly 6, a connecting assembly 7, and a transmission assembly 8. The top surface of the box body 1 is provided with a feed inlet 11, and the crushing assembly 2 is arranged inside the box body 1. The crushing assembly 2 is used for crushing asphalt fragments that enter the box body 1 through the feed inlet 11; the feed hopper 3 is vertically arranged directly above the feed inlet 11, the bottom of the feed hopper 3 is constricted from top to bottom, and the feed hopper 3 is fixedly connected to the box body 1; the feed plate 4 is inclined and arranged inside the feed hopper 3, the top of the feed plate 4 is fixedly connected to the feed hopper 3, and there is a distance for the asphalt fragments to flow between the bottom end of the feed plate 4 and the side wall of the feed hopper 3. The feed plate 4 is used for transporting asphalt fragments.

[0024] It should be noted that the crushing assembly 2 is a prior art, and no specific limitation is imposed on the crushing assembly 2 in the present application.

[0025] The asphalt fragments are transported to the feeding plate 4 through a conveyor belt and slide obliquely downward on the feeding plate 4 by relying on their own gravity. The asphalt fragments fall to the bottom of the feeding hopper 3 through the space reserved between the bottom end of the feeding plate 4 and the side wall of the feeding hopper 3; the metering assembly 5 monitors the amount of asphalt fragments at the bottom of the feeding hopper 3. When the amount of asphalt fragments reaches the preset range, the transmission assembly 8 drives the closing assembly 6 to start, so that the feeding at the bottom of the feeding hopper 3 stops. Then, the transmission assembly 8 drives the state of the connecting assembly 7 to be adjusted, so that the discharging part at the bottom end of the feeding hopper 3 is communicated with the outside, and thus the asphalt fragments can be quantitatively transported to the crushing assembly 2.

[0026] The metering assembly 5 includes a metering rod 51, a first metering member 52 and a second metering member 53. The metering rod 51 is a telescopic rod structure and is vertically arranged below the feeding plate 4. The top end of the metering rod 51 is fixedly connected to the feeding plate 4; the first metering member 52 is located below the metering rod 51 and is fixedly connected to the bottom end of the metering rod 51; the second metering member 53 is located below the first metering member 52 and is fixedly connected to the feeding hopper 3. There is a repulsive force between the second metering member 53 and the first metering member 52.

[0027] The closing assembly 6 includes a closing telescopic plate 61 and a closing spring 62. Among them, the closing telescopic plate 61 is horizontally arranged below the feeding plate 4. The fixed end of the closing telescopic plate 61 is fixedly connected to the feeding plate 4, and the movable end of the closing telescopic plate 61 is used to abut against the side wall of the feeding hopper 3; the closing spring 62 is arranged inside the closing telescopic plate 61 and is used to drive the closing telescopic plate 61 to contract.

[0028] The connecting assembly 7 includes a connecting member 71 and a connecting spring 72. Among them, the connecting member 71 is a telescopic plate structure. The connecting member 71 is horizontally arranged. The fixed end of the connecting member 71 is fixedly connected to the outer wall of the feeding hopper 3. The movable end of the connecting member 71 is inserted into the side wall of the feeding hopper 3 and is used to abut against the inner wall of the feeding hopper 3; the connecting spring 72 is arranged inside the connecting member 71 and is used to drive the connecting member 71 to extend.

[0029] The transmission assembly 8 includes a first transmission part 81 and a second transmission part 82; the first transmission part 81 includes a transmission box 811, a first slider 812, and a first connecting pipe 813. The transmission box 811 is horizontally arranged on one side of the metering rod 51 and fixedly connected to the fixed end of the metering rod 51; the first slider 812 is slidably arranged in the transmission box 811 along the length direction of the transmission box 811. The first slider 812 divides the interior of the transmission box 811 into a waterless area 8111 and a water storage area in sequence along the direction away from the metering rod 51. There is a fluid preset in the water storage area. There is a repulsive force between the first slider 812 and the piston 511 of the metering rod 51. When the first slider 812 and the piston 511 of the metering rod 51 are within a preset range, the first slider 812 can be driven to move by the piston 511 of the metering rod 51; one end of the first connecting pipe 813 is communicated with the water storage area, and the other end is communicated with the plate-free cavity of the closed expansion plate 61. Fluids are preset in the first connecting pipe 813, the water storage area, and the plate-free cavity of the closed expansion plate 61.

[0030] The second transmission part 82 includes a second slider 821 and a second connecting pipe 822. The second slider 821 is slidably arranged in the water storage area. The sliding direction of the second slider 821 is the same as that of the first slider 812. The second slider 821 divides the water storage area into a first transmission water storage area 8112 and a second transmission water storage area 8113 in sequence along the direction away from the first slider 812; among them, the first connecting pipe 813 is communicated with the first transmission water storage area 8112; one end of the second connecting pipe 822 is communicated with the second transmission water storage area 8113, and the other end is communicated with the plate cavity of the connecting member 71. Fluids are preset in the second connecting pipe 822 and the plate cavity of the connecting member 71.

[0031] The connecting spring 72 and the closing spring 62 are always in a compressed state, and the elastic force of the connecting spring 72 is always greater than that of the closing spring 62; during the synchronous movement of the first slider 812 and the second slider 821, the first slider 812 is used to block the communication part between the first connecting pipe 813 and the transmission box 811; when the piston 511 of the metering rod 51 and the first slider 812 are within a preset range, there is a one-way damping effect between the piston 511 of the metering rod 51 and the fixed end of the metering rod 51.

[0032] The implementation principle of the road solid waste treatment and recycling equipment in the embodiment of the present application is as follows: The asphalt fragments are conveyed to the feeding plate 4 by a conveyor belt and slide obliquely downward on the feeding plate 4 by relying on their own gravity. The asphalt fragments fall to the bottom of the feeding hopper 3 through the space reserved between the bottom end of the feeding plate 4 and the side wall of the feeding hopper 3. Since the discharging part at the bottom end of the feeding hopper 3 is isolated from the outside, the asphalt fragments at the bottom of the feeding hopper 3 gradually increase. During the process of the increase of the asphalt fragments, the asphalt fragments will gradually accumulate between the first measuring piece 52 and the second measuring piece 53, so that the repulsive force between the first measuring piece 52 and the second measuring piece 53 gradually decreases, and then the piston 511 of the measuring rod 51 gradually moves downward by relying on its own gravity.

[0033] When the piston 511 of the measuring rod 51 moves downward to a preset range, the piston 511 of the measuring rod 51 generates a repulsive force on the first slider 812, causing the first slider 812 to slide in a direction away from the measuring rod 51. Then, the first slider 812 squeezes the fluid in the first transmission water storage area 8112 into the plate-free cavity of the closed telescopic plate 61 through the first connecting pipe 813, causing the closed telescopic plate 61 to extend. Further, the closed telescopic plate 61 closes the space between the bottom end of the feeding plate 4 and the side wall of the feeding hopper 3.

[0034] After the closed telescopic plate 61 completes the closing work, the first slider 812 continues to move away from the measuring rod 51 under the drive of the piston 511 of the measuring rod 51, causing the first slider 812 to squeeze the second slider 821 through the fluid in the first transmission water storage area 8112, so that the second slider 821 and the first slider 812 move away from the measuring rod 51 together. During the sliding process of the second slider 821, the second slider 821 squeezes the fluid in the second transmission water storage area 8113 into the plate cavity of the connecting part 71 through the second connecting pipe 822, causing the connecting part 71 to contract. Further, the asphalt fragments at the bottom of the feeding hopper 3 can be quantitatively dropped onto the crushing component 2, avoiding the idling state of the crushing component 2, thereby improving the efficiency of solid waste recycling.

[0035] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
