Description

Technical Field

[0001] This invention relates to the field of solid waste recycling technology, specifically to a solid waste recycling mechanism for tunnel construction. Background Technology

[0002] Tunnel construction generates a significant amount of solid waste, such as tunnel slag, shield excavation material, and concrete fragments. To achieve waste reduction, harmlessness, and resource utilization, solid waste recycling facilities are typically used to crush and refine the waste for subsequent recycling.

[0003] For example, the Chinese patent with announcement number CN213559098U, patent application title: An environmentally friendly construction waste recycling device, and announcement date: 2021-06-29, includes a waste recycling bin. The lower surface of the waste recycling bin is fixedly connected to a support leg, the upper surface of the waste recycling bin is fixedly connected to a feed inlet, a crushing hammer is provided on the inner top of the waste recycling bin, and a counter-rotating gear is fixedly connected to the left side of the crushing hammer.

[0004] The existing technologies mentioned above have the following technical problems: When the existing waste recycling equipment is in use, it achieves multiple crushing of waste through rotating crushing parts and reciprocating crushing parts. However, the crushing and crushing parts are operated separately. This means that the waste recycling equipment requires multiple electrical control devices and a large internal space to accommodate the separate crushing and crushing parts, which undoubtedly increases the overall size of the equipment. However, when tunneling, the space inside the tunnel is limited, and the large size of the waste recycling equipment can easily lead to occupying too much effective space.

[0005] Therefore, this application proposes a solid waste recycling mechanism for tunnel construction in order to solve the problems mentioned above. Summary of the Invention

[0006] The purpose of this invention is to provide a solid waste recycling mechanism for tunnel construction, so as to solve the problems currently found in the market as described in the background.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a solid waste recycling mechanism for tunnel construction, comprising an outer casing and a feeding hopper installed on the upper end of the outer casing. The outer casing has a waste-guiding outlet inside, and a separating screen plate is fixed inside the outer casing. A storage hood is located below the separating screen plate, and discharge plates are installed on both sides of the front of the storage hood for conveying the shredded waste onto a conveyor belt. A servo motor is fixed inside the outer casing, and a transmission rod is installed at the output end of the servo motor. A snap-fit ​​block fixed to the side of the transmission rod is inserted into a mating groove opened inside the sleeve pipe. The sleeve pipe and the transmission rod are connected to each other by an auxiliary spring. A shredding unit is connected to the upper end of the sleeve pipe. A main gear is keyed to the transmission rod, and a power rack is meshed to the side of the main gear. The upper end of the power rack is fixed to a side pressure plate. By the relative movement of the side pressure plates located on both sides of the shredding unit and the rotation of the shredding unit, shredding and crushing functions are integrated within the same chamber.

[0008] Preferably, the outer wall of the side locking block of the transmission rod and the inner wall of the mating groove inside the sleeve are in close contact with each other, and the sleeve can move along the vertical direction of the transmission rod.

[0009] By adopting the above technical solution, through the cooperation of the snap-fit ​​block and the mating groove, the sleeve can be driven to rotate synchronously when the transmission rod rotates, without affecting the movement of the sleeve on the transmission rod.

[0010] Preferably, the sleeve can slide on the separation screen plate, and the chopping unit at the upper end of the sleeve is located in the middle of the two side pressure plates.

[0011] By adopting the above technical solution, the rotation of the sleeve is driven by the transmission rod, which enables the shredding unit to shred the solid waste material. At the same time, the downward movement of the sleeve can also cause the shredding unit to move downward synchronously, thereby enabling the shredding unit to play a certain crushing role on the solid waste material.

[0012] Preferably, the chopping unit includes an adjusting column installed on the upper end of the sleeve pipe, and a chopping plate is installed on the side of the adjusting column. A linkage gear is fixed on the rotating shaft of the chopping plate, and the linkage gear is located inside the adjusting column. A guide gear is provided on the side of the linkage gear, and the guide gear is fixed on the upper end of the transmission rod.

[0013] By adopting the above technical solution and adjusting the circumferential shredding plates of the column, the shredding effect on solid waste materials can be improved when the column rotates.

[0014] Preferably, the chopping plate can rotate on the adjusting column via a rotating shaft, and the linkage gear connected by a key on the rotating shaft of the chopping plate forms a meshing transmission structure with the guide gear frame.

[0015] By adopting the above technical solution, when the adjusting column moves downward, the chopping plate can move downward synchronously. After the chopping plate moves downward, the meshing connection between the linkage gear and the guide gear frame can enable the linkage gear to drive the chopping plate to rotate synchronously.

[0016] Preferably, the power rack is located on the front and rear sides of the main gear, and the side pressure plate fixed at the upper end of the power rack can slide on the separation screen plate, and the side of the side pressure plate that contacts the solid waste material is provided with crushing teeth.

[0017] By adopting the above technical solution, the reciprocating rotation of the main gear enables the meshing power rack to drive the side pressure plate to move synchronously, and the movement of the side pressure plate crushes the solid waste material on the separation screen plate.

[0018] Preferably, the lower end of the side pressure plate is connected to the bracket and the limiting sleeve, and the limiting sleeve is installed on the sleeve tube. The limiting sleeve has a guide groove inside, and a connecting plate is inserted into the guide groove. The connecting plate is fixed on the sleeve tube.

[0019] By adopting the above technical solution, the movement of the side pressure plate can be used to make the limiting sleeve move downward along the sleeve connector by utilizing the bracket.

[0020] Preferably, the lower ends of the limiting sleeve and the side pressure plate are hinged to the ends of the sub-supports, and the sub-supports are symmetrically distributed about the central axis of the limiting sleeve, with each sub-support corresponding to one of the side pressure plates.

[0021] By adopting the above technical solution and connecting the sub-supports with hinges, power transmission can be achieved using the sub-supports.

[0022] Preferably, the cross-section of the guide groove inside the limiting sleeve is set to a circular structure, and the inner wall of the guide groove inside the limiting sleeve and the outer wall of the connecting plate fit together, and the connecting plate can rotate in the guide groove inside the limiting sleeve.

[0023] By adopting the above technical solution, through the cooperation of the connecting plate and the guide groove, not only can the sleeve be rotated normally, but also the limiting sleeve can be pushed down synchronously by the connecting plate after moving downward.

[0024] Compared with the prior art, the beneficial effects of the present invention are: the solid waste recycling mechanism for tunnel construction integrates the dual effects of crushing and chopping by setting a crushing component inside the equipment and by rotating and reciprocating up and down of the crushing component, thereby minimizing the size of the device by utilizing integrated functional equipment; 1. Equipped with a shredding unit and a side pressure plate, the rotation of the transmission rod, through the cooperation of the snap-fit ​​block and the docking groove, enables the sleeve to drive the shredding unit to rotate. The rotation of the shredding unit shreds the solid waste material on the separation screen plate. At the same time, the reciprocating rotation of the main gear drives the side pressure plate to move back and forth through the meshing power rack. The movement of the side pressure plate also crushes the solid waste material. By integrating shredding and crushing functions within the same cavity, the size of the device is reduced. 2. A limiting sleeve is set up. The reciprocating movement of the side pressure plate can drive the limiting sleeve to move synchronously through the hinged bracket. The movement of the limiting sleeve can cause the sleeve pipe and the adjusting column to move down synchronously through the connecting plate. The downward movement of the adjusting column can also use the circumferential chopping plate to crush the solid waste material on the separation screen plate, thus giving the chopping plate the dual function of chopping and crushing. 3. Equipped with a shredding plate, the shredding plate moves down synchronously when the adjusting column moves downward. When the shredding plate moves downward, the linkage gear on its rotating shaft meshes with the guide gear frame, thereby driving the shredding plate to rotate on the adjusting column. The rotation of the shredding plate can further improve the shredding effect on solid waste materials. Attached Figure Description

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Example 1: Please refer to Figures 1-9Existing waste recycling equipment uses rotating crushing components and reciprocating crushing components to repeatedly crush waste materials. However, these components operate separately, requiring multiple electrical control devices and a large internal space to accommodate them, thus increasing the overall size of the equipment. In tunnel construction, where space is limited, a large waste recycling system can easily occupy excessive usable space. To address this technical problem, this embodiment discloses the following technical content: a solid waste recycling system for tunnel construction. The receiving mechanism includes an outer casing 1 and a feed hopper 2 installed on the upper part of the outer casing 1. The outer casing 1 has a waste material guiding port 3 inside, and a separating screen plate 4 is fixed inside the outer casing 1. A storage cover 5 is installed below the separating screen plate 4, and discharge plates 6 are installed on both sides of the front of the storage cover 5 to transfer the shredded waste material to the conveyor belt. A servo motor 7 is fixed inside the outer casing 1, and a transmission rod 8 is installed at the output end of the servo motor 7. A snap-fit ​​block 9 fixed on the side of the transmission rod 8 is inserted into a docking groove 11 opened inside the sleeve pipe 10, and the sleeve pipe 10 and the transmission rod 8 are connected by an auxiliary... The auxiliary springs 12 are interconnected. The upper end of the sleeve 10 is connected to the chopping unit 13. The transmission rod 8 is keyed to the main gear 14, and the side of the main gear 14 is meshed with the power rack 15. The upper end of the power rack 15 is fixed to the side pressure plate 16. By the relative movement of the side pressure plates 16 on both sides of the chopping unit 13 and the rotation of the chopping unit 13, the chopping and crushing functions are integrated in the same chamber. The outer wall of the side locking block 9 of the transmission rod 8 and the inner wall of the mating groove 11 inside the sleeve 10 fit together, and the sleeve 10 can move along the vertical direction of the transmission rod 8. The shredding unit 13 at the upper end of the sleeve 10 is located in the middle of the two side pressure plates 16. The power rack 15 is located on the front and rear sides of the main gear 14. The side pressure plate 16 fixed at the upper end of the power rack 15 can slide on the separation screen plate 4. The side of the side pressure plate 16 that contacts the solid waste material is provided with crushing teeth. The lower end of the side pressure plate 16 is connected to the limiting sleeve 18 through the bracket 17. The limiting sleeve 18 is installed on the sleeve 10. The limiting sleeve 18 has a guide groove inside, and a connecting plate 19 is inserted inside the guide groove. The connecting plate 19 is fixed on the sleeve 10.

[0029] When solid waste materials need to be recycled during tunnel construction, they are fed into the outer casing 1 through the feed hopper 2. The solid waste materials then enter the separating screen plate 4 through the distribution port 3. Next, the servo motor 7 is activated, controlling the transmission rod 8 to rotate reciprocally. When the transmission rod 8 rotates, the engagement of the locking block 9 and the docking groove 11 causes the transmission rod 8 to drive the sleeve pipe 10 to rotate synchronously. The rotation of the sleeve pipe 10 drives the chopping unit 13 to rotate synchronously. The rotation of the chopping unit 13 then chops the solid waste materials on the separating screen plate 4. Simultaneously, the rotation of the transmission rod 8 causes the main gear 14 to... When the main gear 14 rotates back and forth, it enables the power rack 15, which is meshed with the front and rear sides, to move back and forth. Since the upper end of the power rack 15 is connected to the side pressure plate 16, the movement of the power rack 15 will cause the side pressure plate 16 to move synchronously. The reciprocating movement of the side pressure plate 16 can crush the solid waste material on the separation screen plate 4. By integrating the crushing and crushing functions into the same chamber, the size of the device is reduced. The crushed solid waste material leaks through the holes on the separation screen plate 4 into the storage hood 5 below. The solid waste material in the storage hood 5 is discharged outward through the discharge plate 6 onto the conveyor for subsequent recycling.

[0030] Example 2: The technical content disclosed in this example is a further improvement based on Example 1 described above. The following technical content is disclosed in this example: Figures 3-9 As shown, the chopping unit 13 includes an adjusting column 131 mounted on the upper end of the sleeve 10, and a chopping plate 132 is mounted on the side of the adjusting column 131. A linkage gear 133 is fixed on the rotating shaft of the chopping plate 132, and the linkage gear 133 is located inside the adjusting column 131. A guide gear frame 134 is provided on the side of the linkage gear 133, and the guide gear frame 134 is fixed on the upper end of the transmission rod 8. The chopping plate 132 can rotate on the adjusting column 131 via the rotating shaft, and the rotating shaft of the chopping plate 132 is keyed to... The linkage gear 133 and the guide gear 134 form a meshing transmission structure. The lower ends of the limiting sleeve 18 and the side pressure plate 16 are hinged to the end of the sub-support 17. The sub-support 17 is symmetrically distributed about the central axis of the limiting sleeve 18. The sub-support 17 and the side pressure plate 16 correspond one-to-one. The cross-section of the guide groove inside the limiting sleeve 18 is set as a circular structure. The inner wall of the guide groove inside the limiting sleeve 18 and the outer wall of the connecting plate 19 fit together. The connecting plate 19 can rotate in the guide groove inside the limiting sleeve 18.

[0031] When the transmission rod 8 rotates, the sleeve 10 rotates synchronously. Since the connecting plate 19 on the sleeve 10 can rotate within the guide groove inside the limiting sleeve 18, it does not affect the rotation of the sleeve 10. The rotation of the sleeve 10 causes the chopping plate 132 on the side of the adjusting column 131 to rotate synchronously, thus chopping the solid waste material. Simultaneously, when the side pressure plate 16 moves towards the center of the separation screen plate 4, the movement of the side pressure plate 16 can push the limiting sleeve 18 downwards via the hinged bracket 17. The movement of the limiting sleeve 18 can then push the sleeve 10 downwards synchronously via the connecting plate 19. After the sleeve 10 moves downwards, the adjusting column 131 at its upper end can also move synchronously. At this time, the movement of the adjusting column 131 can also utilize the circumferential chopping plate 132 to chop the separation screen. The solid waste material on plate 4 plays a certain crushing role, thus giving the shredding plate 132 the dual function of shredding and crushing. After the adjusting column 131 moves downward, the shredding plate 132 moves downward synchronously. When the shredding plate 132 moves downward, the linkage gear 133 on its rotating shaft meshes with the guide gear frame 134 on the transmission rod 8. At this time, the linkage gear 133 drives the shredding plate 132 to rotate. The rotation of the shredding plate 132 can further improve the shredding effect on the solid waste material. When the side pressure plate 16 moves away from the center of the separation screen plate 4 to reset, the side pressure plate 16 is reset and then pulls the limiting sleeve 18 upward synchronously through the bracket 17. After the limiting sleeve 18 moves upward, the sleeve pipe 10 and the adjusting column 131 are reset synchronously. This cycle repeats, thereby improving the crushing and refining effect on the solid waste material.
