Description

Technical Field

[0001] The present invention relates to concrete recycling technology, and particularly to a crushing device for asphalt concrete blocks. Background Art

[0002] There are many solid wastes in construction sites. Among them, concrete waste is the most numerous and difficult to handle solid waste. The accumulation of concrete waste restricts the construction conditions of construction sites and affects construction efficiency. The cone crusher is a mining machine used for crushing stones. Its working principle is that the eccentric mechanism drives the dynamic cone main shaft group to swing eccentrically. The dynamic cone liner on the dynamic cone main shaft group and the fixed cone liner on the fixed cone frame cooperate with each other to crush stones, and can quickly and thoroughly process concrete waste.

[0003] In the Chinese invention patent with the publication number CN116943842A, a crushing treatment device for waste concrete is disclosed. In this waste concrete crushing treatment device, the waste concrete is put into the mixing cylinder, and the crushing mechanism in the mixing cylinder crushes the concrete. The crushed concrete is filtered and screened through the vibration mechanism. At the same time, the adsorption mechanism adsorbs the iron blocks in the concrete. The iron blocks on the outer circumferential side wall of the support cylinder fall into the first collection box. The fourth connecting shaft drives the fan to rotate, and the fan blows the wood chips and the like in the concrete into the third collection box. The concrete is transported to the second collection box through the discharging mechanism, and can comprehensively remove the impurities in the waste concrete and thoroughly crush the waste concrete.

[0004] When the existing equipment is in use, since the concrete blocks often contain metal parts such as steel bars, most of the internal steel bars are sorted manually. However, smaller metal parts are difficult to be found, resulting in a large number of metal parts in the crushed concrete, which affects the subsequent utilization of the crushed concrete. At the same time, after removing the metal parts in the concrete, it is necessary to manually put the concrete into the crushing equipment again for secondary operation, which is not only cumbersome but also consumes a large amount of labor.

[0023] Embodiment: Please refer to Figures 1 - 10, An asphalt concrete block crushing device, including a base 1, a crushing part 12 is fixedly installed at the end of the base 1. At the same time, a protective ring 11 is fixedly installed on one side of the base 1. A screening component 2 is clamped on the inner wall of the protective ring 11. The end of the screening component 2 is communicated with the crushing part 12. The metal parts in the concrete block are screened out through the screening component 2.

[0024] In this solution, the crushing part 12 is composed of a motor and two crushing rollers. The two crushing rollers are driven to rotate by the motor, and then the concrete block is initially crushed. The protective ring 11 is composed of two half-rings spliced together, and after splicing, it is locked by bolts and other fixing components to ensure that the overall screening component 2 remains stable during operation.

[0025] Further, among them, the screening component 2 includes a cylinder 21 clamped with the protective ring 11. A transmission plate 22 is fixedly installed on the inner wall of the cylinder 21, and the cross-section of the transmission plate 22 is trapezoidal.

[0026] In this embodiment, the crushed concrete is exported into the interior of the transmission plate 22 through the crushing part 12. Since the cross-section of the transmission plate 22 is trapezoidal, the caliber at the upper end of the transmission plate 22 is larger than that at the lower end, so as to aggregate the concrete and introduce it from the small caliber at the lower end of the transmission plate 22 onto the protective plate 28.

[0027] Further, a guide block 23 is fixedly installed on the inner wall of the cylinder 21. At the same time, one side of the guide block 23 penetrates and extends to the outside of the cylinder 21, and a support rod 24 is fixedly installed at the end of the guide block 23.

[0028] Specifically, the support rod 24 is located in the middle of the cylinder 21. At the same time, a telescopic device such as an electric telescopic rod is arranged in the inner cavity of the support rod 24 and is connected to an external control device, so that when the electric telescopic rod is started, a ring 25 slidably installed on the outer surface of the support rod 24 is driven to move.

[0029] Further, a ring 25 is slidably installed on the outer surface of the support rod 24. A plurality of moving rods 251 are rotatably installed on the outer surface of the ring 25, and the plurality of moving rods 251 are evenly distributed on the outer surface of the ring 25. A magnetic sector plate 26 is rotatably installed at the end of the moving rod 251. A limiting rod 27 is rotatably installed at the end of the magnetic sector plate 26, and the end of the limiting rod 27 is fixedly connected to the outer surface of the support rod 24.

[0030] Specifically, when the ring 25 moves, it synchronously drives the moving rods 251 rotatably installed on its outer surface to move. Since the magnetic sector plate 26 is rotatably installed at the end of the moving rod 251, when the moving rod 251 moves, the magnetic sector plate 26 is driven to move.

[0031] At the same time, a limiting rod 27 is rotatably installed at one end of the magnetic sector plate 26 away from the moving rod 251, and the limiting rod 27 is fixedly installed on the outer surface of the support rod 24, so that the magnetic sector plate 26 rotates around the end of the limiting rod 27.

[0032] The magnetic sector plate 26 is an electromagnet, which is convenient for controlling the magnetic force in real time. When the magnetic sector plate 26 contracts, the power supply is stopped, and then the adsorbed metal parts fall into the interior of the export block 23, which is convenient for subsequent collection. After cleaning is completed, the magnetic sector plate 26 is restored to its initial position, and this reciprocating operation is used to remove metal parts in the concrete. Prevent these metal substances from entering the subsequent processing equipment, thereby avoiding wear or damage to the equipment caused by metal impurities.

[0033] Furthermore, a protective plate 28 is fixedly installed at the end of the export block 23. A docking groove 281 corresponding to the magnetic sector plate 26 is formed on the outer surface of the protective plate 28, and the inner wall of the docking groove 281 is slidably connected to the outer surface of the magnetic sector plate 26. The cross-section of the protective plate 28 is trapezoidal. At the same time, a buffer block 29 is fixedly installed at the end of the protective plate 28, and the buffer block 29 penetrates and extends into the inner cavity of the transfer plate 22 Specifically, the protective plate 28 is integrally frustum-shaped. When the transfer plate 22 exports the concrete to the outer surface of the protective plate 28, the concrete moves downward along the outer surface of the protective plate 28, and the metal in the concrete is adsorbed by the magnetic sector plate 26.

[0034] A buffer component such as a spring is provided between the buffer block 29 and the end of the protective plate 28. The buffer block 29 buffers the falling concrete, making the operation of the equipment more stable and extending the service life of the equipment.

[0035] Furthermore, a through hole 231 is formed at the end of the export block 23, and the other end of the through hole 231 communicates with the inner cavity of the protective plate 28.

[0036] Specifically, the collected metal parts are conveyed through the through hole 231 on the export block 23. At the same time, the through hole 231 is overall in an inclined state. When the parts fall into the hole 231, they are exported through the inclined hole 231, which is convenient for collecting the collected metal parts.

[0037] Furthermore, the rolling component 3 is assembled at the lower end of the screening component 2, and the screened concrete blocks are processed secondarily through the rolling component 3; the rolling component 3 includes a fixing plate 31 fixedly connected to the cylinder 21, and a rotating block 32 is fixedly installed at the end of the fixing plate 31. A plurality of extrusion plates 321 are fixedly installed at the end of the rotating block 32, and the plurality of extrusion plates 321 are evenly distributed at the end of the rotating block 32. At the same time, the ends of the plurality of extrusion plates 321 are combined into a tapered block.

[0038] In this embodiment, a docking plate is provided on the outer surface of the fixing plate 31, and the docking plate is fixedly connected to the inner wall of the cylinder 21. The entire rolling assembly 3 is fixed at the middle position of the inner cavity of the cylinder 21 through the docking plate. A convex block corresponding to the pressing plate 321 is provided on the outer surface of the rotating block 32, and the convex block penetrates and extends to the outside of the positioning plate 34. The convex block is fixedly connected to the pressing plate 321, so that when the rotating block 32 rotates, the entire pressing plate 321 is driven to rotate synchronously.

[0039] At the same time, a pressing plate 39 is fixedly installed on the inner wall of the cylinder 21 and above the pressing plate 321, and the pressing plate 39 is generally conical. When the concrete falls inside the pressing plate 39, it cooperates with the pressing plate 321 to perform secondary rolling on the concrete.

[0040] Furthermore, a turntable 33 is fixedly installed at the end of the rotating block 32, and a driving rod 331 is rotatably installed on the outer surface of the turntable 33. A positioning plate 34 is fixedly installed at the end of the fixing plate 31. A plurality of guiding grooves 341 are provided at the end of the positioning plate 34, and the plurality of guiding grooves 341 are evenly distributed at the end of the positioning plate 34. A guiding block 35 is slidably installed on the inner wall of the guiding groove 341, and the end of the guiding block 35 is rotatably connected to the end of the driving rod 331.

[0041] Specifically, when the turntable 33 rotates, the driving rod 331 rotatably installed on its outer surface is synchronously driven to move. Since the end of the driving rod 331 is rotatably connected to the end of the guiding block 35, when the driving rod 331 moves, the guiding block 35 is driven to move along the inner wall of the guiding groove 341 until it reaches the optimal position and stops.

[0042] Furthermore, a driving member 38 is fixedly installed at one end of the positioning plate 34 away from the turntable 33. The output end of the driving member 38 penetrates and extends into the positioning plate 34, and the output end of the driving member 38 is fixedly connected to the end of the turntable 33.

[0043] Specifically, the driving member 38 is a device with power output such as a motor and is connected to an external control device. When the driving member 38 is started, the turntable 33 provided at its output end is synchronously driven to rotate.

[0044] Furthermore, a guiding rod 36 is fixedly installed at the end of the guiding block 35. The end of the guiding rod 36 penetrates and extends to the outside of the positioning plate 34. At the same time, an arc-shaped plate 37 is fixedly installed at the end of the guiding rod 36, and the concrete is rolled by the arc-shaped plate 37.

[0045] Specifically, when the guiding block 35 moves, it synchronously drives the guiding rod 36 fixedly installed at its end to move. Since the arc-shaped plate 37 is fixedly installed at the end of the guiding rod 36, the concrete is rolled again through the movement of the arc-shaped plate 37, so that the concrete is extruded with the cylinder 21 until the concrete meets the requirements and then stops. After removing metal impurities, the purity of the crushed concrete particles is relatively high, without metal impurities, improving the quality of the final concrete crushing.

[0046] The control device can select a single-chip microcomputer as the control terminal. In this embodiment, the single-chip microcomputer is a typical embedded microcontroller (Micro controller Unit), which is composed of an arithmetic unit, a controller, a memory, input and output devices, etc., equivalent to a microcomputer. Compared with the general-purpose microprocessor applied in personal computers, it emphasizes more on self-supply (without external hardware) and cost savings. Its greatest advantage is its small size, which can be placed inside the instrument, but its storage capacity is small, the input and output interfaces are simple, and the function consumption is low.

[0047] Only some exemplary embodiments of the present invention have been described above by way of illustration. Undoubtedly, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present invention.
