Description

Technical Field

[0001] The invention relates to a concrete recycling technology, in particular to an asphalt concrete block crushing device. Background Art

[0002] There are many solid wastes in construction sites, among which concrete waste is the most numerous and difficult to handle. The accumulation of concrete waste limits the construction conditions on the construction site and affects the construction efficiency. The cone crusher is a mining machine used to crush stones. Its working principle is to drive the eccentric rotation of the movable cone main shaft group through the eccentric mechanism. The movable cone liner on the movable cone main shaft group and the fixed cone liner on the fixed cone frame cooperate with each other to crush stones, which can quickly and thoroughly handle concrete waste.

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

[0004] When existing equipment is used, since concrete blocks often contain metal parts such as steel bars, the internal steel bars are mostly sorted manually, but smaller metal parts are difficult to detect, resulting in a large number of metal parts in the crushed concrete, affecting the subsequent use of the crushed concrete. At the same time, after the metal parts in the concrete are removed, the concrete needs to be manually put into the crushing equipment again for a secondary operation, which is not only cumbersome but also requires a lot of labor. Therefore, an asphalt concrete block crushing device has been developed. Summary of the Invention

[0036] The following will provide a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0037] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the devices or components referred to must have a specific direction, be constructed and operate in a specific direction. Therefore, they should not be understood as limiting the present invention. The terms "first", "second", and "third" are used for descriptive purposes only and should not be understood as indicating or implying relative importance. In addition, unless otherwise expressly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, they can be fixedly connected, detachably connected, or integrally connected; they can be mechanically connected or electrically connected; they can be directly connected or indirectly connected through an intermediate medium, or they can be internal communication between two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0038] Example: See Figures 1-10 A device for crushing asphalt concrete blocks includes a base 1, a crushing piece 12 is fixedly mounted on the end of the base 1, and a protective ring 11 is fixedly mounted on one side of the base 1. A screening component 2 is clamped on the inner wall of the protective ring 11, and the end of the screening component 2 is connected to the crushing piece 12. The metal parts in the concrete block are screened out through the screening component 2.

[0039] In this embodiment, the crushing element 12 comprises a motor and two crushing rollers. The motor drives the two crushing rollers to rotate, thereby initially crushing the concrete blocks. The protective ring 11 is composed of two half rings, which are locked with bolts or other fixing components after the splicing is completed, thereby ensuring that the screening assembly 2 remains stable during operation.

[0040] Furthermore, the screening assembly 2 includes a cylinder 21 clamped with the protective ring 11, and a transmission plate 22 is fixedly mounted on the inner wall of the cylinder 21, and the cross section of the transmission plate 22 is trapezoidal.

[0041] In this embodiment, the crushed concrete is guided out of the interior of the transmission plate 22 by the crushing member 12. Since the cross-section of the transmission plate 22 is trapezoidal, the diameter of the upper end of the transmission plate 22 is larger than the diameter of the lower end, thereby aggregating the concrete and guiding it onto the protective plate 28 through the small diameter at the lower end of the transmission plate 22.

[0042] Furthermore, a guide block 23 is fixedly mounted on the inner wall of the cylinder 21 , and one side of the guide block 23 passes through and extends to the outside of the cylinder 21 , and a support rod 24 is fixedly mounted on the end of the guide block 23 .

[0043] Specifically, the support rod 24 is located in the middle position of the cylinder 21. At the same time, the inner cavity of the support rod 24 is provided with a device with telescopic function such as an electric telescopic rod, and is connected to an external control device, so that when the electric telescopic rod is started, the ring 25 slidably installed on the outer surface of the support rod 24 is driven to move.

[0044] Furthermore, a circular ring 25 is slidably installed on the outer surface of the support rod 24, and multiple groups of moving rods 251 are rotatably installed on the outer surface of the circular ring 25, and the multiple groups of moving rods 251 are evenly distributed on the outer surface of the circular ring 25. The end of the moving rod 251 is rotatably installed with a magnetic sector plate 26, and the end of the magnetic sector plate 26 is rotatably installed with a limiting rod 27, and the end of the limiting rod 27 is fixedly connected to the outer surface of the support rod 24.

[0045] Specifically, when the ring 25 moves, it synchronously drives the moving rod 251 installed on its outer surface to move. Since the end of the moving rod 251 is rotatably installed with a magnetic sector plate 26, when the moving rod 251 moves, the magnetic sector plate 26 is driven to move.

[0046] At the same time, the magnetic sector plate 26 is rotatably mounted on one end away from the moving rod 251 with the limiting rod 27 , and the limiting rod 27 is fixedly mounted 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 .

[0047] The magnetic sector plate 26 is an electromagnet that allows for real-time control of the magnetic force. When the magnetic sector plate 26 contracts, the power is turned off, allowing the adsorbed metal parts to fall into the outlet block 23 for subsequent collection. After cleaning, the magnetic sector plate 26 returns to its initial position. This reciprocating operation is used to remove metal parts from concrete, preventing these metals from entering subsequent processing equipment, thereby preventing metal impurities from causing wear or damage to the equipment.

[0048] Furthermore, a protective plate 28 is fixedly mounted on the end of the output block 23. The outer surface of the protective plate 28 is provided with a docking groove 281 corresponding to the magnetic sector plate 26. 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 mounted on the end of the protective plate 28. The buffer block 29 passes through and extends to the inner cavity of the transmission plate 22.

[0049] Specifically, the protective plate 28 is in a truncated cone shape as a whole. When the transmission plate 22 guides the concrete out of 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 .

[0050] The ends of the buffer block 29 and the protective plate 28 are provided with springs and other components with a buffering effect. The buffer block 29 buffers the concrete when it falls, making the equipment run more smoothly and extending the service life of the equipment.

[0051] Furthermore, a through hole 231 is formed at the end of the outlet block 23 , and the other end of the through hole 231 is communicated with the inner cavity of the protective plate 28 .

[0052] Specifically, the collected metal parts are transported through the through hole 231 on the export block 23. At the same time, the through hole 231 is tilted as a whole. When the parts fall into the hole 231, they are exported through the tilted hole 231, which facilitates the collection of the collected metal parts.

[0053] Furthermore, a compacting assembly 3, mounted at the lower end of the screening assembly 2, performs secondary processing on the screened concrete blocks. The compacting assembly 3 includes a fixed plate 31 fixedly connected to the cylinder 21, with a rotating block 32 fixedly mounted at the end of the fixed plate 31. Multiple sets of extrusion plates 321 are fixedly mounted at the end of the rotating block 32, and the multiple extrusion plates 321 are evenly distributed at the end of the rotating block 32. The ends of the multiple extrusion plates 321 merge into a tapered block.

[0054] In this embodiment, a docking plate is provided on the outer surface of the fixed plate 31, and the docking plate is fixedly connected to the inner wall of the cylinder 21. The entire rolling assembly 3 is fixed in the middle position of the inner cavity of the cylinder 21 through the docking plate. The outer surface of the rotating block 32 is provided with a protrusion corresponding to the extrusion plate 321, and the protrusion passes through and extends to the outside of the positioning plate 34. It is fixedly connected to the extrusion plate 321 through the protrusion, so that when the rotating block 32 rotates, the entire extrusion plate 321 is synchronously driven to rotate.

[0055] At the same time, a pressing plate 39 is fixedly installed on the inner wall of the cylinder 21 and at the upper end of the extrusion plate 321. The pressing plate 39 is cone-shaped as a whole. When concrete falls inside the pressing plate 39, the extrusion plate 321 cooperates with the concrete to perform secondary rolling.

[0056] Furthermore, a rotating disk 33 is fixedly mounted on the end of the rotating block 32, and a drive rod 331 is rotatably mounted on the outer surface of the rotating disk 33. A positioning plate 34 is fixedly mounted on the end of the fixed plate 31. The end of the positioning plate 34 is defined by multiple sets of guide grooves 341, and these sets of guide grooves 341 are evenly distributed along the end of the positioning plate 34. A guide block 35 is slidably mounted on the inner wall of the guide groove 341, and the end of the guide block 35 is rotatably connected to the end of the drive rod 331.

[0057] Specifically, when the turntable 33 rotates, the drive rod 331 installed on its outer surface is synchronously driven to move. Since the end of the drive rod 331 is rotatably connected to the end of the guide block 35, when the drive rod 331 moves, the guide block 35 is driven to move along the inner wall of the guide groove 341 until it reaches the optimal position and stops.

[0058] Furthermore, a driving member 38 is fixedly mounted on one end of the positioning plate 34 away from the turntable 33 . The output end of the driving member 38 passes through and extends into the interior of the positioning plate 34 . The output end of the driving member 38 is fixedly connected to the end of the turntable 33 .

[0059] 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, it synchronously drives the turntable 33 provided at its output end to rotate.

[0060] Furthermore, a guide rod 36 is fixedly mounted on the end of the guide block 35 , and the end of the guide rod 36 passes through and extends to the outside of the positioning plate 34 . At the same time, an arc plate 37 is fixedly mounted on the end of the guide rod 36 , and the concrete is compacted by the arc plate 37 .

[0061] Specifically, when the guide block 35 moves, it simultaneously drives the guide rod 36 fixed to its end to move. Since the end of the guide rod 36 is fixedly mounted with a curved plate 37, the curved plate 37 moves to further compress the concrete, squeezing the concrete against the cylinder 21 until the concrete meets the requirements. This results in the crushed concrete particles being of higher purity and free of metallic impurities after removing metallic impurities, thus improving the quality of the final concrete crushing.

[0062] The control device can use a single-chip microcomputer as the control terminal. In this embodiment, the single-chip microcomputer is a typical embedded microcontroller (MCU), consisting of an arithmetic unit, a controller, memory, and input / output devices, equivalent to a miniature computer. Compared to the general-purpose microprocessors used in personal computers, it emphasizes self-sufficiency (no external hardware required) and cost savings. Its greatest advantages are its small size, allowing it to be placed inside the instrument, low memory capacity, simple input / output interfaces, and low functional consumption.

[0063] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.
