Description

Technical Field

[0001] This invention relates to the field of building material waste recycling technology, specifically to a device for recycling and reusing building material waste. Background Technology

[0002] Construction waste refers to the slag, waste soil, waste materials, silt and other waste generated by construction units or individuals during the construction, laying or demolition and repair of various buildings, structures, pipelines, etc. In order to achieve the recycling of construction waste, it is generally recycled and processed. In this process, construction waste is crushed by construction waste crushing equipment.

[0003] See Figure 8 Traditional construction waste crushing devices typically use two crushing teeth rotating in opposite directions to crush the construction waste placed between them. Since construction waste contains hard stones and concrete, the crushing teeth will suffer wear and chipping after a certain number of years of use. If not repaired in time, the crushing quality and efficiency will be affected. The crushing teeth of traditional crushing devices are welded or machined into one piece, which makes replacement and maintenance inconvenient.

[0004] Based on this, the present invention designs a device for recycling and reusing building material waste to solve the above problems. Summary of the Invention

[0007] The blocking device includes a fixed shaft, which is fixedly connected to the side of the crushing roller. A torsion spring is sleeved on the surface of the fixed shaft. One end of the torsion spring is fixedly connected to the crushing roller, and the other end of the torsion spring is fixedly connected to an L-shaped blocking rod. The L-shaped blocking rod is rotatably connected to the surface of the fixed shaft, and the end of the L-shaped blocking rod is in contact with a trapezoidal block. A plurality of circularly arrayed mounting blocks are fixedly connected to the side of the crushing roller. The side of each mounting block is in contact with the L-shaped blocking rod. A pushing rod that penetrates the mounting block is slidably connected to the side of each mounting block. A pushing spring is sleeved on the surface of the pushing rod, and both ends of the pushing spring are fixed to the mounting block and the pushing rod, respectively.

[0008] The release device includes a rectangular sliding shell, which is fixedly connected to the side of the crushing shell. The side of the crushing shell has a through groove adapted to the rectangular sliding shell. The bottom inner wall of the rectangular sliding shell has a through mounting groove. The inner wall of the mounting groove is rotatably connected to a mounting shaft that passes through the mounting groove. A gear is rotatably connected to the surface of the mounting shaft. The gear is adapted to a first toothed plate. A closing plate is fixedly connected to the inner wall of the end of the rectangular sliding shell. A rectangular shell is fixedly connected to the bottom of the rectangular sliding shell. A touch plate is slidably connected to the inner wall of the rectangular shell. The touch plate passes through the crushing shell. A second toothed plate is provided on the side of the touch plate. The second toothed plate is adapted to the gear. The end of the touch plate is inclined. The touch plate is adapted to a push rod and a rectangular groove.

[0009] As a further embodiment of the present invention, a reset plate is fixedly connected to the end surface of the irregular rod, a reset spring is connected to the side of the reset plate, and the other end of the reset spring is fixedly connected to the surface of the trapezoidal block.

[0010] As a further embodiment of the present invention, the power device includes two first gears, the first gears being fixedly connected to the end of the rotating shaft, a motor being fixedly connected to the side of the crushing housing, a second gear being fixedly connected to the end of the output shaft of the motor, and a third gear being rotatably connected to the side of the crushing housing. The second gear meshes with the first gear and the third gear, and the second gear and the third gear are gears of the same specification.

[0011] As a further embodiment of the present invention, a mounting plate is fixedly connected to the side of the first gear, and a level is fixedly connected to the top surface of the mounting plate, with an arrow provided on the side of the level.

[0012] As a further embodiment of the present invention, two fixing blocks are fixedly connected to the top of the connecting rod, and a placement groove is provided on the top surface of the trapezoidal block, and the fixing blocks are slidably connected to the inner wall of the placement groove.

[0013] As a further embodiment of the present invention, two limiting plates are fixedly connected to the inner wall end of the rectangular shell, and the touch plate and the limiting plates are slidably connected.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. This invention features a detachable structure including a trapezoidal block and crushing teeth. A first spring guides the trapezoidal block into the inner wall of a rectangular sliding shell. Simultaneously, a gear drives the trapezoidal block to continue sliding within the shell. The trapezoidal structure of the inner wall prevents the block from bouncing up and down, thus preventing it from engaging with the gear. The sealing plate presses against the shaped rod, causing the connecting rod to enter the large hole of the figure-eight shaped hole. This releases the crushing teeth from their restricted position, allowing damaged crushing teeth to be easily removed for repair or replacement. This method offers high repair efficiency, is simple and quick, and avoids the inconvenience caused by welding or integral machining of the crushing teeth.

[0016] 2. This invention, by setting an eight-shaped hole on the irregularly shaped rod, makes limiting and releasing the connecting rod simple and convenient. When the connecting rod is in the small hole position, the inner wall of the small hole and the inner wall of the recessed groove are precisely interlocked. At the same time, the narrowest point where the inner walls of the large hole and the small hole meet is slightly smaller than the diameter of the inner wall of the recessed groove, ensuring that the connecting rod will not leave the center of the small hole and is stably limited in the small hole. Only external force can cause the irregularly shaped rod to enter the large hole and thus escape the limitation of the small hole. See [link to relevant documentation]. Figure 16 , Figure 17 .

[0017] 3. In order to ensure the accurate positioning of the trapezoidal groove and the through groove, and to ensure that the trapezoidal block can slide smoothly into the through groove, the present invention requires that when rotating the shaft, the bubble in the level indicator at the stop position of the shaft be in the position indicated by the arrow. At this time, the accurate positioning of the trapezoidal groove and the through groove can be guaranteed. Attached Figure Description

[0038] 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.

[0039] Please see Figure 1-17This invention provides a technical solution: a device for recycling and reusing construction material waste, comprising a crushing shell 1, characterized in that: two rotating shafts 2 are rotatably connected to the inner wall of the crushing shell 1, and crushing rollers 3 are fixedly connected to the surfaces of the two rotating shafts 2; multiple rectangular grooves 4 arranged in a circular array are opened on the side of the crushing rollers 3, and multiple trapezoidal grooves 5 arranged in a circular array are opened on the surface of the crushing rollers 3; two guide rods 41 are fixedly connected to the inner wall of the trapezoidal grooves 5, and a first spring 6 is sleeved on the surface of the guide rods 41; one end of the first spring 6 is fixedly connected to the inner wall of the trapezoidal grooves 5; a trapezoidal block 7 is slidably connected to the inner wall of the trapezoidal grooves 5; a first toothed plate 8 is provided at the bottom of the trapezoidal block 7; a through-hole 9 and two guide holes 10 are opened on the side of the trapezoidal block 7, and the guide holes 10 are composed of two holes of different diameters combined; the guide holes 10 and the guide rods 41 are connected... The long groove 9 is slidably connected to the inner wall of a special-shaped rod 11. The surface of the special-shaped rod 11 is provided with multiple figure-eight holes 42, which are divided into large holes 12 and small holes 13. The top of the long groove 9 is provided with a through connecting hole 14. The inner wall of the connecting hole 14 is slidably connected to a connecting rod 15. The bottom of the connecting rod 15 is provided with a recessed groove 16. The inner wall of the recessed groove 16 is in contact with the inner wall of the small hole 13. The bottom inner wall of the long groove 9 is fixedly connected to multiple second springs 17. The other end of the second spring 17 is in contact with the bottom of the connecting rod 15. The top of the connecting rod 15 is fixedly connected to a crushing tooth 18. The side of the crushing roller 3 is connected to a blocking device that blocks the movement of multiple circumferentially distributed trapezoidal blocks 7. The side of the crushing shell 1 is connected to four sets of release devices that release the limit of the crushing tooth 18. The side of the crushing shell 1 is connected to a power device.

[0040] The blocking device includes a fixed shaft 19, which is fixedly connected to the side of the crushing roller 3. A torsion spring 20 is sleeved on the surface of the fixed shaft 19. One end of the torsion spring 20 is fixedly connected to the crushing roller 3, and the other end of the torsion spring 20 is fixedly connected to an L-shaped blocking rod 21. The L-shaped blocking rod 21 is rotatably connected to the surface of the fixed shaft 19. The end of the L-shaped blocking rod 21 is in contact with the trapezoidal block 7. Multiple circular array mounting blocks 22 are fixedly connected to the side of the crushing roller 3. The side of the mounting block 22 is in contact with the L-shaped blocking rod 21. A pushing rod 23 that passes through the mounting block 22 is slidably connected to the side of the mounting block 22. A pushing spring 24 is sleeved on the surface of the pushing rod 23. The two ends of the pushing spring 24 are fixed to the mounting block 22 and the pushing rod 23, respectively.

[0041] The release device includes a rectangular sliding shell 25, which is fixedly connected to the side of the crushing shell 1. The side of the crushing shell 1 has a through groove 26 that matches the rectangular sliding shell 25. The bottom inner wall of the rectangular sliding shell 25 has a through mounting groove 43. The inner wall of the mounting groove 43 is rotatably connected to a mounting shaft 44 that passes through the mounting groove 43. A gear 27 is rotatably connected to the surface of the mounting shaft 44. The gear 27 matches the first toothed plate 8. A closing plate 28 is fixedly connected to the inner wall of the end of the rectangular sliding shell 25. A rectangular shell 29 is fixedly connected to the bottom of the rectangular sliding shell 25. A touch plate 30 is slidably connected to the inner wall of the rectangular shell 29. The touch plate 30 passes through the crushing shell 1. A second toothed plate 31 is provided on the side of the touch plate 30. The second toothed plate 31 matches the gear 27. The end of the touch plate 30 is inclined. The touch plate 30 matches the push rod 23 and the rectangular groove 4.

[0042] During operation, first stop the equipment. Manually rotate the shaft 2 to rotate the damaged crushing tooth 18 to the position corresponding to the release device, i.e., the position corresponding to the trapezoidal groove 5 and the through groove 26. Install the touch plate 30 into the rectangular shell 29 and push the touch plate 30 to slide along the inner wall of the rectangular shell 29. After the touch plate 30 slides to the position of the gear 27, the second toothed plate 31 on its side will mesh with the gear 27 and drive the gear 27 to rotate. As the touch plate 30 continues to move, the inclined surface at its end will press the push rod 23. The pressed push rod 23 will compress the push spring 24 and its end will press the L-shaped... The L-shaped blocking rod 21 will rotate under the pressure of the jacking rod 23 until it stops blocking the trapezoidal block 7. At this point, the inclined end of the touch plate 30 is just about to enter the rectangular groove 4. After the trapezoidal block 7 is released from the obstruction, it pops out under the action of the first spring 6. The trapezoidal block 7 slides along the trapezoidal groove 5 and enters the inner wall of the through groove 26 and the rectangular sliding shell 25. At this time, the first toothed plate 8 at the bottom of the trapezoidal block 7 will mesh with the gear 27. Since the inner wall of the rectangular sliding shell 25 is a trapezoidal structure, the trapezoidal block 7 will not jump up and down, thus preventing it from meshing with the gear 27. The actuating plate 30 then enters the rectangular groove 4 and continues to slide, simultaneously driving the gear 27 to continue rotating. The rotating gear 27 drives the trapezoidal block 7 to continue moving into the rectangular sliding shell 25. The trapezoidal block 7 will gradually drive the end of the shaped rod 11 to contact the sealing plate 28. The shaped rod 11 will be squeezed and move backward. At this time, the recessed groove 16 will gradually detach from the contact with the inner wall of the small hole 13 and gradually enter the large hole 12. When the center of the recessed groove 16 and the center of the large hole 12 are basically coincident, since the diameter of the large hole 12 is slightly larger than the diameter of the connecting rod 15, the connecting rod 15 will pop out under the action of the second spring 17, thereby driving the crushing tooth 18 to pop out, so that the crushing tooth 18 is released from the limited state. At this time, the actuating plate 30 has moved to the calibrated position and no longer pushes the actuating plate 30 to move. The damaged crushing tooth 18 can be easily removed for repair or replacement. The repair efficiency is high, simple and quick. After the repair is completed, it can be reset.

[0043] As a further embodiment of the present invention, a reset plate 32 is fixedly connected to the end surface of the irregular rod 11, and a reset spring 33 is connected to the side of the reset plate 32. The other end of the reset spring 33 is fixedly connected to the surface of the trapezoidal block 7. During operation, after the crushing tooth 18 is replaced, the irregular rod 11 needs to be reset. When the irregular rod 11 is pressed, it drives the reset plate 32 to squeeze the reset spring 33, so that the reset spring 33 stores elastic potential energy. When the irregular rod 11 is reset and the pressure is released, the elastic potential energy of the reset spring 33 is converted into kinetic energy to drive the irregular rod 11 to reset.

[0044] As a further embodiment of the present invention, the power unit includes two first gears 34, which are fixedly connected to the end of the rotating shaft 2. A motor 45 is fixedly connected to the side of the crushing housing 1, and a second gear 35 is fixedly connected to the end of the output shaft of the motor 45. A third gear 36 is rotatably connected to the side of the crushing housing 1. The second gear 35 meshes with the first gear 34 and the third gear 36. The second gear 35 and the third gear 36 are gears of the same specification. During operation, since the second gear 35 and the second gear 34 are gears of the same specification, i.e., the module, number of teeth and other parameters are the same, when driving the first gear 34 to rotate, the rotation speed of the two first gears 34 remains the same, thereby ensuring the crushing efficiency.

[0045] As a further embodiment of the present invention, a mounting plate 46 is fixedly connected to the side of the first gear 34, and a level 37 is fixedly connected to the top surface of the mounting plate 46. An arrow is provided on the side of the level 37. During operation, in order to ensure that the corresponding positions of the trapezoidal groove 5 and the through groove 26 are accurate, and to ensure that the trapezoidal block 7 can slide smoothly along the trapezoidal groove 5 into the through groove 26, when the rotating shaft 2 is rotated, it is necessary to ensure that the bubble in the level 37 at the stop position of the rotating shaft 2 is at the position indicated by the arrow. At this time, the corresponding positions of the trapezoidal groove 5 and the through groove 26 are accurate.

[0046] As a further embodiment of the present invention, two fixing blocks 38 are fixedly connected to the top of the connecting rod 15, and a placement groove 39 is provided on the top surface of the trapezoidal block 7. The fixing blocks 38 are slidably connected to the inner wall of the placement groove 39. During operation, since the connecting rod 15 at the bottom of the crushing tooth 18 is circular, it can rotate. In order to prevent it from rotating, the fixing blocks 38 are provided so that when the crushing tooth 18 is installed in place, the fixing blocks 38 will enter the placement groove 39, thus avoiding the problem of the crushing tooth 18 rotating.

[0047] As a further embodiment of the present invention, two limiting plates 40 are fixedly connected to the inner wall end of the rectangular shell 29, and the touch plate 30 and the limiting plates 40 are slidably connected. During operation, by setting the limiting plates 40, the left and right sliding of the touch plate 30 is limited, so that it can move in a predetermined direction, and the problem of the touch plate 30 not being able to enter the rectangular groove 4 due to excessive left and right shaking occurs.
