Description
Technical Field
[0001] This utility model relates to the field of waste recycling technology, specifically to an engineering waste recycling device. Background Technology
[0002] The recycling of construction waste can not only reduce environmental pollution, but also realize the reuse of resources and promote sustainable development. For example, waste concrete blocks, bricks, gypsum boards, etc., can be ground and crushed into recycled aggregates, which can be used to produce recycled concrete, recycled bricks and other building materials.
[0003] Currently, when using grinding and pulverizing equipment to process industrial waste, only the rotation of one grinding head can be used to pulverize the industrial waste, resulting in low grinding efficiency and affecting the recycling efficiency of engineering waste. Summary of the Invention
[0004] This invention addresses the problem of low grinding efficiency in engineering waste recycling by providing an engineering waste recycling device that improves the recycling efficiency of engineering waste.
[0005] To solve the above problems, the technical solution of this utility model is:
[0006] An engineering waste recycling device includes a shell with a discharge gate on the lower part of its peripheral wall, a grinding cylinder, a grinding body, and a driving component. The grinding cylinder is a cylinder with a discharge hole in the middle, rotatably connected to the upper part of the shell. A vertical cylinder is provided on the bottom surface of the shell. The grinding body is rotatably mounted on the upper end of the vertical cylinder and coaxially disposed in the discharge hole. The distance between the peripheral wall of the grinding body and the inner wall of the discharge hole gradually decreases from top to bottom. The driving component includes a driving ring and a screw. A sliding hole is provided on the peripheral wall of the shell outside the grinding cylinder, and a spiral groove is provided on the outer wall of the grinding cylinder. The driving ring is sleeved on the outside of the shell, and a driving rod is connected to the inner ring of the driving ring. The free end of the driving rod passes through the sliding hole and extends into the spiral groove. The driving ring is driven by the screw to move upward or downward. When the driving ring moves upward or downward, the grinding body and the grinding cylinder move in opposite directions of rotation.
[0007] Furthermore, the feeding hole is a frustum-shaped hole that is larger at the top and smaller at the bottom, and the grinding body is a frustum-shaped columnar body that is larger at the top and smaller at the bottom. The inner wall of the feeding hole is evenly distributed with protrusion one, and the peripheral wall of the grinding body is evenly distributed with protrusion two.
[0008] Furthermore, the lower end of the vertical cylinder is fixedly connected to the bottom plate of the shell; a guide plate is provided inside the shell, which is an elliptical plate with a lower left side and a higher right side. The guide plate is sleeved on the outside of the vertical cylinder through a through hole in the middle. The peripheral wall of the guide plate is fixedly connected to the inner wall of the shell. The discharge gate is located on the left side of the peripheral wall of the shell and is higher than the left end of the guide plate.
[0009] Furthermore, a horizontal plate is fixed to the upper end of the right outer wall of the housing, a motor is fixed to the top surface of the horizontal plate, a screw threadedly connects to the drive ring, and the upper end of the screw passes through the horizontal plate to connect to the motor output end.
[0010] Furthermore, the screw and the grinding body are connected by a transmission component, which includes a rotating rod one and a rotating rod two. The rotating rod one is located inside the vertical cylinder, and its upper end passes through the top plate of the vertical cylinder and connects to the grinding body. The rotating rod one is rotatably connected to the top plate of the vertical cylinder. A bevel gear one is fixedly fitted on the rotating rod one, with the bevel gear one being larger at the top and smaller at the bottom. One end of the rotating rod two passes through the peripheral wall of the vertical cylinder and is connected to a bevel gear two that meshes with the bevel gear one. The other end of the rotating rod two passes through the peripheral wall of the housing and is connected to a bevel gear three. The small ends of the bevel gear two and the bevel gear three are opposite to each other. The lower end of the peripheral wall of the screw is connected to a bevel gear four that meshes with the bevel gear three, with the bevel gear four being larger at the top and smaller at the bottom. The rotating rod two is rotatably connected to the peripheral wall of the housing.
[0011] Furthermore, the spiral groove has a right-hand spiral direction, and when the screw rotates counterclockwise, the drive ring moves downward.
[0012] The beneficial effects of this utility model through the above technical solution are as follows:
[0013] When this invention is in use, the motor drives the screw to rotate counterclockwise or clockwise, and both the grinding cylinder and the grinding body can rotate in opposite directions. The engineering waste between the grinding body and the grinding cylinder can be ground and crushed by both the second protrusion on the grinding body and the first protrusion on the grinding cylinder. Since the grinding body and the grinding cylinder rotate in opposite directions, the engineering waste can be subjected to forces in different directions. Therefore, this invention can crush the engineering waste more quickly.
[0014] This invention enables convenient collection of engineering waste after grinding and pulverizing, guided by a feed plate. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:
[0021] like Figures 1-4 As shown, an engineering waste recycling device includes a housing 1, which is a cylinder with an open top. A discharge gate 2 is provided on the lower part of the peripheral wall of the housing 1. The device also includes a grinding cylinder 3, a grinding body 4, and a driving component. The grinding cylinder 3 is a cylinder with a discharge hole 5 in the middle. The grinding cylinder 3 is rotatably connected to the upper part of the housing 1. A vertical cylinder 6 is provided on the bottom surface of the housing 1. The grinding body 4 is rotatably mounted on the upper end of the vertical cylinder 6 and coaxially disposed within the discharge hole 5. The distance between the peripheral wall of the grinding body 4 and the inner wall of the discharge hole 5 gradually decreases from top to bottom. The driving component includes a driving ring 7 and a screw 8. The outer wall of the outer shell 1 of the grinding cylinder 3 is provided with a sliding hole 9, which is a rectangular hole opened along the height direction of the shell 1. The outer wall of the grinding cylinder 3 is provided with a spiral groove 10. The driving ring 7 is a ring body whose inner diameter matches the outer diameter of the shell 1. The driving ring 7 is sleeved on the outer shell 1. A driving rod 11 is connected to the inner ring of the driving ring 7. The free end of the driving rod 11 passes through the sliding hole 9 and extends into the spiral groove 10. The driving ring 7 is driven by the screw 8 to move upward or downward. When the driving ring 7 moves upward or downward, the grinding body 4 and the grinding cylinder 3 move in opposite directions of rotation.
[0022] Limiting ring 12 is fixed on the inner wall of the shell 1 on the upper side of the grinding cylinder 3, and limiting ring 23 is fixed on the inner wall of the shell 1 on the lower side of the grinding cylinder 3. The upper and lower sides of the grinding cylinder 3 are in sliding contact with limiting ring 12 and limiting ring 23 respectively, and the discharge gate 2 is lower than limiting ring 23.
[0023] The feeding hole 5 is a frustum-shaped hole that is larger at the top and smaller at the bottom, and the grinding body 4 is a frustum-shaped column that is larger at the top and smaller at the bottom. The inner wall of the feeding hole 5 is evenly distributed with protrusion 14, and the peripheral wall of the grinding body 4 is evenly distributed with protrusion 25.
[0024] The vertical cylinder 6 is a cylindrical body with an open bottom end, and the bottom plate of the housing 1 is fixedly connected to the bottom end of the vertical cylinder 6. A guide plate 16 is provided inside the housing 1. The guide plate 16 is an elliptical plate with a lower left side and a higher right side. The guide plate 16 is sleeved on the outside of the vertical cylinder 6 through a through hole in the middle. The periphery of the guide plate 16 is fixedly connected to the inner wall of the housing 1. The discharge gate 2 is located on the left side of the periphery of the housing 1 and is higher than the left end of the guide plate 16.
[0025] A horizontal plate 17 is fixed to the upper end of the right outer wall of the housing 1. A motor 18 is fixed to the top surface of the horizontal plate 17. A screw 8 is threadedly connected to a drive ring 7. The upper end of the screw 8 passes through the horizontal plate 17 and connects to the output end of the motor 18. The motor 18 selected in this utility model is model F5D200-24GU-18S. The output shaft of this model of motor 18 can rotate forward or backward.
[0026] The screw 8 and the grinding body 4 are connected by a transmission component, which includes a rotating rod 19 and a rotating rod 20. The rotating rod 19 is located inside the vertical cylinder 6. The upper end of the rotating rod 19 passes through the top plate of the vertical cylinder 6 and connects to the grinding body 4. The rotating rod 19 is rotatably connected to the top plate of the vertical cylinder 6 via a bearing 1. A bevel gear 21 is fixedly fitted on the rotating rod 19. The bevel gear 21 is larger at the top and smaller at the bottom. One end of the rotating rod 20 passes through the peripheral wall of the vertical cylinder 6 and is connected to a bevel gear 22 that meshes with the bevel gear 21. The other end of the rotating rod 20 passes through the peripheral wall of the housing 1 and is connected to a bevel gear 23. The small ends of the bevel gears 2 and 3 are opposite to each other. The lower end of the peripheral wall of the screw 8 is connected to a bevel gear 24 that meshes with the bevel gear 23. The bevel gear 24 is larger at the top and smaller at the bottom. The rotating rod 20 is located below the guide plate 16 and is rotatably connected to the peripheral wall of the housing 1 via a bearing 2.
[0027] The spiral groove 10 has a right-hand spiral direction. When the screw 8 rotates counterclockwise, the drive ring 7 moves downward; the counterclockwise rotation of the screw 8 is... Figure 2 A bird's-eye view.
[0028] In use, the engineering waste that needs to be ground and pulverized is fed into the gap between the grinding body 4 and the grinding cylinder 3. The motor 18 first drives the screw 8 to rotate counterclockwise (the counterclockwise rotation of the screw 8 is...). Figure 2(From a top-down perspective), driven by the screw 8, the drive ring 7 drives the drive rod 11 to move downwards. The free end of the drive rod 11 presses against the spiral groove 10. Since the spiral groove 10 rotates to the right, the downward movement of the drive rod 11 drives the grinding cylinder 3 to rotate counterclockwise. When the screw 8 rotates counterclockwise, the bevel gear 24 rotates counterclockwise along with the screw 8. When the bevel gear 24 rotates, it meshes with the bevel gear 23 on the rotating rod 20, and the bevel gear 22 on the rotating rod 20 meshes with the bevel gear 21 on the rotating rod 19. When the screw 8 rotates, it drives the rotating rod 19 through the transmission of the rotating rod 20. When rotated clockwise, the grinding body 4 rotates clockwise along with the rotating rod 19. The grinding body 4 and the grinding cylinder 3 rotate in opposite directions. The engineering waste between the grinding body 4 and the grinding cylinder 3 can be ground and crushed by both the protrusions 15 on the grinding body 4 and the protrusions 14 on the grinding cylinder 3. When the drive rod 11 moves to the lower end of the sliding hole 9, the motor 18 drives the screw 8 to rotate clockwise. At this time, the drive ring 7 moves upward, the grinding cylinder 3 rotates clockwise, and the grinding body 4 rotates counterclockwise. When the drive rod 11 moves to the upper end of the sliding hole 9, the motor 18 drives the screw 8 to rotate counterclockwise again.
[0029] Therefore, when the motor 18 drives the screw 8 to rotate counterclockwise or clockwise, the grinding cylinder 3 and the grinding body 4 can rotate in opposite directions, and the engineering waste between the grinding body 4 and the grinding cylinder 3 can be ground and crushed more quickly; the crushed engineering waste falls onto the guide plate 16 through the lower end of the discharge hole 5, and moves to the left under the guidance of the guide plate 16, opening the discharge gate 2 to collect the crushed engineering waste.

However, the present utility model is not limited to the above embodiments. Any equivalent or equivalent modifications or substitutions to the technical solutions of the present utility model without departing from the spirit of the present utility model or the scope of disclosure shall fall within the protection scope of the present utility model.
