Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically a device for processing renewable building materials. Background Technology

[0002] Demolition of old buildings generates a lot of construction waste, such as concrete blocks, bricks, and boards. In underdeveloped areas and cities, most of the waste is directly transported to the suburbs or countryside and dumped in the open or landfilled. If these wastes are not treated or recycled, they will cause environmental pollution. Therefore, the demand for renewable construction waste recycling equipment is increasing. In order to improve the recycling efficiency of renewable construction waste, it is usually necessary to crush the renewable construction waste first.

[0003] In existing renewable waste processing devices, construction waste is typically crushed to meet recycling standards. After crushing, the waste needs to be screened through a sieve. The crushed waste falls below the sieve, and as more waste accumulates on the sieve, it can easily cause clogging, potentially interrupting waste processing and damaging the sieve, thus reducing the efficiency of crushing. To address these issues, we provide a renewable building material processing device. Utility Model Content

[0004] The purpose of this invention is to provide a renewable building material processing device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0007] The ring frame and the screen are connected by a first linkage structure. When the ring frame rotates, it will drive the screen to move up and down.

[0008] The sleeve and the ring frame are connected by a second linkage structure. When the ring frame rotates, it pulls the sleeve downward.

[0010] A renewable building material processing device as described above: a motor is fixed on the barrel lid, and the output end of the motor is connected to a rotating shaft through a coupling. The motor is used to drive the rotating shaft to rotate.

[0011] A renewable building material processing device as described above: the outer edge of the screen is provided with an arc-shaped protrusion, and the center of the screen is provided with a through hole whose inner diameter matches the outer diameter of the sleeve.

[0012] A renewable building material processing device as described above: the snap-fit ​​assembly includes a first snap-fit ​​groove formed in the inner wall of the crushing barrel and a protrusion fixed to the outer edge of the screen. The protrusion is slidably snapped into the first snap-fit ​​groove and can slide up and down in the first snap-fit ​​groove.

[0013] A renewable building material processing device as described above: the first linkage structure includes a plurality of circumferentially arranged arc-shaped protrusions fixed on the upper surface of a ring frame and a plurality of rollers disposed at the bottom of a screen. A plurality of supports are fixed at the bottom of the screen, and the rollers are rotatably mounted on the supports and roll on the upper surface of the arc-shaped protrusions.

[0015] A renewable building material processing device as described above: a keyway is provided on the rotating shaft, a key is fixed on the inner wall of the sleeve, and the key is movably engaged inside the keyway and can slide up and down inside the keyway.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: A rotating shaft is installed inside the crushing barrel, and the screen is movably engaged inside the crushing barrel via a snap-fit ​​assembly, allowing it to move up and down.

The crushed material falls below the screen after being sieved.

[0017] A ring frame is fixed at the bottom of the rotating shaft; the sleeve and the ring frame are connected by a second linkage structure. When the ring frame rotates, it will pull the sleeve downward, so that the rotating shaft will rotate and drive the ring frame to rotate. The ring frame pulls the sleeve downward and applies a downward pulling force to the extrusion roller, so that the extrusion roller can fully extrude the building material on the screen when it rolls on the screen, thereby improving the crushing effect of the building material.

[0018] In addition, the ring frame and the screen are connected by a first linkage structure. When the ring frame rotates, it will drive the screen to move up and down. In turn, when the rotating shaft rotates, it will drive the ring frame to rotate synchronously, thereby causing the screen to move up and down and shake. Through the reciprocating shaking of the screen, the crushed building materials on the screen can be shaken off by vibration, avoiding excessive accumulation of waste on the screen and causing the screen holes to be blocked, thereby improving the screening effect of the screen and increasing the efficiency of crushing.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] Please see Figures 1 to 8 As an embodiment of this utility model, a renewable building material processing device includes a crushing barrel 1 with a top opening, a barrel cover 2 installed at the top opening of the crushing barrel 1, a discharge pipe 3 fixed at the bottom of the crushing barrel 1, a feed hopper 5 fixed at the top, a rotating shaft 6 rotatably installed inside the crushing barrel 1, a screen 8 installed inside the crushing barrel 1, the screen 8 being movably snapped into the inside of the crushing barrel 1 by a snap-fit ​​assembly and being able to move up and down, a sleeve 11 being movably snapped onto the rotating shaft 6, a plurality of extrusion rollers 12 being rotatably installed on the outer peripheral wall of the sleeve 11, a bevel gear ring 13 being fixed on the inner wall of the crushing barrel 1, a bevel gear 14 meshing with the bevel gear ring 13 being fixed at one end of the extrusion roller 12, and an annular frame 15 being fixed at the bottom end of the rotating shaft 6;

[0030] The ring frame 15 and the screen 8 are connected by a first linkage structure. When the ring frame 15 rotates, it will drive the screen 8 to move up and down.

[0031] The sleeve 11 and the ring frame 15 are connected by a second linkage structure. When the ring frame 15 rotates, it will pull the sleeve 11 to move downward.

[0032] In this embodiment, a rotating shaft 6 is rotatably mounted inside the crushing barrel 1. A screen 8 is movably engaged inside the crushing barrel 1 via a snap-fit ​​assembly and can move up and down. A sleeve 11 is movably engaged on the rotating shaft 6. Multiple extrusion rollers 12 are rotatably mounted on the outer periphery of the sleeve 11. A bevel gear ring 13 is fixed to the inner wall of the crushing barrel 1. One end of each extrusion roller 12 is fixed with a bevel gear 14 that meshes with the bevel gear ring 13. Thus, when the rotating shaft 6 rotates, it drives the extrusion rollers 12 to roll on the screen 8, crushing the building materials on the screen 8. The crushed material falls below the screen 8 after being sieved.

[0033] A ring frame 15 is fixed at the bottom of the rotating shaft 6; the sleeve 11 and the ring frame 15 are connected by a second linkage structure. When the ring frame 15 rotates, it will pull the sleeve 11 downward. Thus, the rotating shaft 6 will rotate and drive the ring frame 15 to rotate. When the ring frame 15 pulls the sleeve 11 downward, it will apply a downward pulling force to the extrusion roller 12, so that the extrusion roller 12 can fully extrude the building material on the screen 8 when it rolls on the screen 8.

[0034] In addition, the ring frame 15 and the screen 8 are connected by a first linkage structure. When the ring frame 15 rotates, it will drive the screen 8 to move up and down. Then, when the rotating shaft 6 rotates, it will drive the ring frame 15 to rotate synchronously, thereby driving the screen 8 to move up and down and shake. Through the up and down reciprocating shaking of the screen 8, the broken building materials on the screen 8 can be shaken off by vibration.

[0035] As a further embodiment of this utility model, a plurality of support legs 4 are fixed on the outer periphery of the crushing barrel 1, and the support legs 4 are used to support the crushing barrel 1.

[0036] In this embodiment, the crushing barrel 1 is stably supported by multiple support legs 4.

[0037] As a further embodiment of this utility model, a motor 7 is fixed on the bucket lid 2, and the output end of the motor 7 is connected to the rotating shaft 6 through a coupling. The motor 7 is used to drive the rotating shaft 6 to rotate.

[0038] In this embodiment, the starter motor 7 can drive the rotating shaft 6 to rotate, so that when the rotating shaft 6 rotates, it can drive the sleeve 11 and the ring frame 15 to rotate.

[0039] As a further embodiment of this utility model, the outer edge of the screen 8 is provided with an arc-shaped protrusion, and the center of the screen 8 is provided with a through hole whose inner diameter is adapted to the outer diameter of the sleeve 11.

[0040] In this embodiment, the outer edge of the screen 8 is provided with an arc-shaped protrusion, which allows the building materials falling on the screen 8 to automatically slide down to the surface of the screen 8 under the action of gravity, avoiding accumulation at the edge of the screen 8 and ensuring that the building materials on the screen 8 are fully broken. The screen 8 has a through hole at its center with an inner diameter that matches the outer diameter of the sleeve 11, allowing the sleeve 11 to slide up and down inside the screen 8.

[0041] As a further embodiment of this utility model, the snap-fit ​​assembly includes a first snap-fit ​​groove 9 formed on the inner wall of the crushing barrel 1 and a protrusion 10 fixed on the outer edge of the screen 8. The protrusion 10 is slidably snapped into the first snap-fit ​​groove 9 and can slide up and down within the first snap-fit ​​groove 9.

[0042] In this embodiment, the protrusion 10 is slidably engaged inside the first slot 9, and the crushing barrel 1 provides limiting support for the screen 8. The protrusion 10 can slide up and down inside the first slot 9, ensuring that the screen 8 has space to shake up and down.

[0043] As a further embodiment of this utility model, the first linkage structure includes a plurality of circumferentially arranged arc-shaped protrusions 16 fixed on the upper surface of the ring frame 15 and a plurality of rollers 17 disposed at the bottom of the screen 8. A plurality of supports are fixed at the bottom of the screen 8, and the rollers 17 are rotatably mounted on the supports and roll on the upper surface of the arc-shaped protrusions 16.

[0044] In this embodiment, since multiple arc-shaped protrusions 16 are arranged and distributed, there are crests and troughs between the multiple arc-shaped protrusions 16. When the roller 17 rolls on the arc-shaped protrusions 16, it will pass through the crests and troughs in sequence, thereby moving up and down, so that the screen 8 can move up and down, and then shake up and down when the roller 17 rolls.

[0045] As a further embodiment of this utility model, the second linkage structure includes multiple grooves 18 fixed to the inner wall of the ring frame 15. A locking block 19 is slidably engaged in the groove 18. A hinge rod 20 is fixed between the locking block 19 and the inner wall of the groove 18. A spring 21 is provided between the locking block 19 and the sleeve 11. The two ends of the spring 21 are respectively connected to the sleeve 11 and the locking block 19. A sliding groove 25 is provided at the bottom of the groove 18. A counterweight block 22 is fixed at the bottom of the locking block 19 and slidably engaged in the sliding groove 25.

[0046] In this embodiment, when the rotating shaft 6 rotates, it drives the sleeve 11 to rotate synchronously, thereby driving the counterweight 22 to rotate. The centrifugal force generated by the rotation of the counterweight 22 pulls the locking block 19 to the side away from the sleeve 11. As the locking block 19 moves, it pulls the spring 21 to the outward side, thereby using the spring 21 to apply a vertical downward component force to the sleeve 11, thus dragging the sleeve 11 downward. The squeezing roller 12, which is rotatably mounted on the sleeve 11, applies a downward pulling force to the squeezing roller 12.

[0047] As a further embodiment of this utility model, a keyway 23 is provided on the rotating shaft 6, and a key 24 is fixed on the inner wall of the sleeve 11. The key 24 is movably engaged inside the keyway 23 and can slide up and down inside the keyway 23.

[0048] In this embodiment, the key 24 is movably engaged inside the keyway 23 and can slide up and down inside the keyway 23, so that when the rotating shaft 6 rotates, it will drive the sleeve 11 to rotate synchronously, and the sleeve 11 can also move up and down around the outer periphery of the rotating shaft 6.

[0049] The working principle of this utility model is as follows: Building materials are added into the crushing barrel 1 through the feeding hopper 5. A rotating shaft 6 is installed inside the crushing barrel 1. The screen 8 is movably engaged inside the crushing barrel 1 through a snap-fit ​​assembly and can move up and down. A sleeve 11 is movably engaged on the rotating shaft 6. Multiple extrusion rollers 12 are rotatably mounted on the outer peripheral wall of the sleeve 11. A bevel gear ring 13 is fixed to the inner wall of the crushing barrel 1. One end of the extrusion roller 12 is fixed with a bevel gear 14 that meshes with the bevel gear ring 13. Thus, when the rotating shaft 6 rotates, it drives the extrusion roller 12 to rotate. By utilizing the meshing of the bevel gear ring 13 and the bevel gear 14, the extrusion roller 12 also rotates on its own axis while rotating. Thus, the extrusion roller 12 rolls on the screen 8 to crush the building materials on the screen 8. The crushed material falls below the screen 8 after being screened. During the crushing process, an annular frame 15 is fixed to the bottom of the rotating shaft 6. The sleeve 11 and the annular frame 15 are connected by a second linkage structure. As the ring frame 15 rotates, it pulls the sleeve 11 downwards, causing the rotating shaft 6 to rotate and simultaneously drive the ring frame 15 to rotate. The ring frame 15 pulls the sleeve 11 downwards, applying a downward pulling force to the extrusion roller 12. This allows the extrusion roller 12 to fully compress the building materials on the screen 8 as it rolls, thus improving the crushing effect. Furthermore, the ring frame 15 and the screen 8 are connected by a first linkage structure. As the ring frame 15 rotates, it drives the screen 8 to move up and down. Consequently, the rotating shaft 6 rotates, causing the ring frame 15 to rotate synchronously, resulting in the screen 8 moving up and down and vibrating. This reciprocating vibration of the screen 8 dislodges the crushed building materials, preventing excessive waste accumulation and screen clogging, thereby improving the screening effect of the screen 8. The crushed building materials fall to the bottom of the crushing barrel 1 and are eventually discharged through the discharge pipe 3.

[0050] The above embodiments are exemplary and not restrictive. Therefore, without departing from the spirit or basic characteristics of this utility model, any technical solutions that can be implemented in other specific forms are included in this utility model.
