Description

Technical Field

[0001] This invention relates to the field of concrete processing technology, and in particular to an energy-saving device for processing concrete for building applications. Background Technology

[0002] In the concrete processing, crushing equipment is used to break construction waste or large concrete raw materials into smaller particles for subsequent processing and resource reuse. Uncrushed large concrete blocks are bulky, inconvenient to transport and reprocess, and difficult to use directly as recycled aggregate. After being processed by crushing equipment equipped with energy-saving motors, the particle size can be effectively reduced and the processing efficiency improved. Since the crushed concrete particles are of different sizes, they need to be further sorted by a screening structure. The screening structure can separate particles of different sizes to achieve standardization and classification management of aggregates, making it easier to select materials with appropriate particle sizes according to different engineering or process requirements.

[0003] In existing concrete crushing and screening equipment, after prolonged use, stones can become embedded in the filter holes of the filter structure, causing blockage and severely affecting the filtration effect. In such cases, the concrete crushing and screening equipment needs to be stopped, and users need to use special unclogging tools to unclog each filter hole before the equipment can resume operation. This process is cumbersome, labor-intensive, and inefficient. Summary of the Invention

[0004] The purpose of this invention is to solve the problem that in existing concrete crushing and screening equipment, after prolonged use, stones become embedded in the filter holes of the filter structure, causing blockage and severely affecting the filtration effect. In such cases, the concrete crushing and screening equipment needs to be stopped, and users need to use special unclogging tools to unclog each filter hole before the equipment can continue to operate.

[0013] Optionally, the self-avoidance component includes an extension block, an inclined rod, a common block, and an end face cam. The top side of the edge plate has a top horizontal groove, the top of the guide plate has an inclined surface, and the other end of the horizontal cylinder is fixedly provided with an edge cover. The top side of the edge cover has a discharge groove.

[0014] Optionally, the bottom end of the inclined surface faces the side of the discharge trough, an extension block is fixedly provided on the side of the guide plate, a guide frame is fixedly provided on the edge plate at the middle position of the top horizontal groove, and the inner wall of the guide frame is fixedly connected to one end of the horizontal spring.

[0016] Optionally, the inner wall of the horizontal cylinder is symmetrically and fixedly provided with an edge frame, and the side of the guide plate is movably inserted into the side of the edge frame.

[0017] Optionally, the workbench has a material drop chute below the horizontal cylinder, and an extension box is fixedly installed at the bottom of the material drop chute.

[0018] Optionally, the end face cam is concentrically fixed at one end of the horizontal column, the end face cam is hollow, the top column extends into the end face cam, and one end of the end face cam is provided with an inclined section and a top horizontal section in sequence.

[0019] Compared with the prior art, the present invention has the following advantages:

[0020] 1. This invention features a horizontal cylinder rotatably mounted below the crushing assembly, with a storage box inside for screening crushed concrete blocks. Concrete particles conforming to the screening size flow out of the storage box, while stones larger than the screening size are intercepted. One end of the horizontal cylinder is equipped with a drive assembly and a self-clearing hole assembly that tilts the intercepted stones. When the drive assembly rotates the horizontal cylinder to tilt the intercepted stones, the purely mechanical self-clearing hole assembly automatically clears the screening holes of the storage box without manual intervention. This invention offers advantages such as simple operation, automatic clearing, and continuous operation, effectively avoiding downtime maintenance caused by stone blockage in the screening holes. It significantly improves screening efficiency and equipment stability, reduces manual labor intensity and safety risks, and enhances overall operational continuity and economy.

[0021] 2. The present invention is provided with a driving component for tilting the intercepted stones, a self-passing hole component, and a material guiding component at one end of the horizontal cylinder. When the material guiding component performs screening in the storage box inside the horizontal cylinder, it can not only guide the concrete particles that meet the screening size from the storage box, but also prevent the concrete particles that meet the screening size from falling into the top of the material guiding component, thus preventing the material guiding component from passing through the screening hole of the storage box to clear the blockage.

[0022] 3. This invention features an edge plate at the bottom side of the storage box, with a self-avoidance component at the bottom side of the edge plate. When the material guiding component performs screening within the storage box inside the horizontal cylinder, the two guide plates merge, guiding concrete particles that meet the screening size from the storage box. When the drive component rotates the horizontal cylinder to dump intercepted stones, the purely mechanical self-avoidance component separates the two guide plates as the horizontal cylinder rotates, providing an avoidance path for the purely mechanical self-through-hole component and sufficient space for its unblocking action. It requires no electrical control or sensors, relying entirely on mechanical linkage to achieve automatic avoidance and unblocking. This not only reduces system complexity and failure rate but also avoids the problem of guide plates interfering with the unblocking path, improving the coordination, reliability, and maintenance convenience of the equipment, achieving true full-process automatic linkage.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0038] Reference Figure 1-12An energy-saving processing device for concrete in construction includes a workbench 3, a suspension platform 1 fixedly mounted on the top of the workbench 3, a guide hopper 7 fixedly mounted on the top of the suspension platform 1, and an installation box 71 fixedly mounted on the bottom of the guide hopper 7. A crushing component for crushing concrete raw materials is mounted on the side of the installation box 71. The crushing component includes a drive motor 9, a dual-shaft reducer 10, and crushing rollers 11. The drive motor 9 is fixedly mounted on the top of an edge frame 2, which is fixedly connected to the top of the workbench 3. A dual-shaft reducer 10 is fixedly mounted at the output end of the drive motor 9, and crushing rollers 11 are fixedly mounted at the output ends of the dual-shaft reducer 10. The dual-shaft reducer 10 is a common motor accessory in the prior art, having one input end and two output ends with opposite rotation directions. The two crushing rollers 11 mesh with each other and rotate in opposite directions, crushing the material fed into the guide hopper 7. To save energy, both the drive motor 9 and the switching motor 19 described below are energy-saving motors.

[0039] A guide cone 13 is fixedly installed at the bottom of the mounting box 71. A large support plate 8 is fixedly installed below the guide cone 13 on the workbench 3. A horizontal cylinder 16 is rotatably connected to the side of the large support plate 8. A storage box 20 for temporarily storing aggregates to be separated is installed inside the horizontal cylinder 16. The horizontal cylinder 16 is attached to the bottom of the guide cone 13. The guide cone 13 has a structure that is wider at the top and narrower at the bottom, which guides the material crushed by the crushing component into the storage box 20. In order for the horizontal cylinder 16 to remain in contact with the bottom of the guide cone 13 when it rotates, the top of the storage box 20 is set as an arc surface. A material drop chute 5 is opened below the horizontal cylinder 16 on the workbench 3. An extension box 4 is fixedly installed at the bottom of the material drop chute 5 on the workbench 3. The material drop chute 5 and the extension box 4 are used to guide the intercepting stones released when the opening of the storage box 20 is facing downwards into the storage device.

[0040] A drive assembly is provided at one end of the horizontal cylinder 16 to automatically tilt the storage box 20 to screen stones. The drive assembly includes a driven belt ring 161, a drive belt 17, and a drive pulley 18. A switching motor 19 is fixedly installed on the side of the small support plate 6. The output end of the switching motor 19 is fixedly installed with the drive pulley 18. The driven belt ring 161 is fixedly installed at one end of the horizontal cylinder 16. The driven belt ring 161 and the drive pulley 18 are jointly fitted with the drive belt 17, and the diameter of the driven belt ring 161 is larger than that of the drive pulley 18. The switching motor 19 can drive the horizontal cylinder 16 to rotate slowly and decelerate through the driven belt ring 161, the drive belt 17, and the drive pulley 18. The switching motor 19 is selected as a servo motor. The driven belt ring 161 and the drive pulley 18 are both set as synchronous pulleys. The drive belt 17 is selected as a synchronous belt. Therefore, by reasonably setting the controller of the switching motor 19, the driven belt ring 161, the drive pulley 18, and the drive belt 17 can be used to drive the horizontal cylinder 16 to rotate at a specific angle.

[0041] The inner cavity of the horizontal cylinder 16 is equipped with a self-clearing hole assembly that automatically clears the blocked mesh of the storage box 20 when the storage box 20 is tilted to screen stones. The self-clearing hole assembly includes a horizontal column 22, a common plate 26, a drive cam 23, and a connecting block 33. The driven belt ring 161 is a hollow ring. An edge plate 21 is fixedly installed on the side wall of the storage box 20. Above the self-clearing hole assembly, the edge plate 21 is equipped with a material guiding assembly that guides the screened particles to discharge. The material guiding assembly includes a material guiding plate 25, an extension block 29, and a self-avoidance assembly that drives the material guiding plate 25 to automatically avoid when the storage box 20 is tilted to screen stones.

[0042] A drive cam 23 is fixedly installed on the outer wall of the horizontal column 22. One end of the horizontal column 22 is rotatably connected to the head of the internal support column 15, and the other end of the horizontal column 22 is fixedly connected to the side of the small support plate 6. The small support plate 6 is fixedly connected to the top of the workbench 3. The bottom of the internal support column 15 is fixedly connected to the inner wall of the horizontal cylinder 16. The top of the common plate 26 is provided with equidistant unblocking columns 261, and the bottom of the storage box 20 is provided with equidistant screening holes 201. The unblocking columns 261 and the screening holes 201 have the same diameter and their positions correspond one-to-one.

[0043] A connecting block 33 is symmetrically fixed on the side of the common plate 26, and a vertical groove 211 is symmetrically opened on the side of the edge plate 21. The connecting block 33 extends into the vertical groove 211, and a vertical column 34 is movably inserted into the top of the connecting block 33. The vertical column 34 is fixedly connected to the top of the vertical groove 211. A vertical spring 35 is sleeved on the top of the vertical column 34 and the connecting block 33. The small end of the drive cam 23 is at the top. When the vertical spring 35 is not subjected to external force, the bottom of the common plate 26 remains in contact with the outer contour of the drive cam 23.

[0044] The self-avoidance assembly includes an extension block 29, an inclined rod 30, a common block 31, and an end face cam 24. The top side of the edge plate 21 has a top horizontal groove 210, and the top of the guide plate 25 has an inclined surface 251. The other end of the horizontal cylinder 16 is fixedly provided with an edge cover 12. The top side of the edge cover 12 has a discharge groove 121. The bottom end of the inclined surface 251 faces the side of the discharge groove 121. The side of the guide plate 25 is fixedly provided with an extension block 29. The inner wall of the horizontal cylinder 16 is symmetrically fixedly provided with an edge frame 14. The side of the guide plate 25 is movably inserted into the side of the edge frame 14. The edge frame 14 prevents material from leaking into the gaps of the multiple drainage columns 261 on the top of the common plate 26 when the two guide plates 25 are in contact with each other.

[0045] A guide frame 27 is fixedly installed in the middle of the top horizontal groove 210 on the edge plate 21. The inner wall of the guide frame 27 is fixedly connected to one end of the horizontal spring 28. The other end of the horizontal spring 28 is fixedly connected to the side of the common block 31. A top column 32 is fixedly installed on the top of the common block 31. The common block 31 is rotatably connected to one end of the inclined rod 30. The other end of the inclined rod 30 is rotatably connected to the side of the extension block 29. The end face cam 24 is concentrically fixed at one end of the horizontal column 22. The end face cam 24 is hollow. The top column 32 extends into the end face cam 24. An inclined section 242 and a top horizontal section 241 are sequentially provided at one end of the end face cam 24. The top horizontal section 241 is parallel to the plane where the end of the end face cam 24 is located.

[0046] The specific implementation steps and principles of this invention are as follows:

[0047] When the entire crushing and screening equipment is working normally, the top opening of the storage box 20 is vertically upward, the common plate 26 is in contact with the top of the drive cam 23, and the top column 32 is in contact with the top of the inclined section 242 of the end face cam 24. At this time, the two guide plates 25 are in a fully contacted state. The worker feeds the material into the space between the two crushing rollers 11 through the guide hopper 7. The two crushing rollers 11 crush the material. The material to be screened enters the storage box 20. The storage box 20 screens the material. The material that meets the screening particle size flows out from the screening hole 201 and is finally discharged from the discharge chute 121 after passing through the inclined surface 251.

[0048] When the storage tank 20 intercepts the falling stones, the switching motor 19 drives the horizontal cylinder 16 to rotate by a set angle via the driving pulley 18, the drive belt 17, and the driven belt ring 161.

[0049] At this time, the opening of the storage box 20 faces downward, and the intercepted stones are discharged from the discharge chute 5 and the extension box 4. During this period, the top column 32 moves from the inclined section 242 to the top horizontal section 241 in sequence. The top column 32 will gradually move away from the small support plate 6. The two inclined rods 30 push the two guide plates 25 away from each other. At the same time, the bottom of the common plate 26 rotates and is pushed by the outer contour of the drive cam 23, which pushes the unblocking column 261 at the top of the common plate 26 through the screening hole 201, thus unblocking all the screening holes 201.

[0050] After waiting for a period of time, the switching motor 19 drives the horizontal cylinder 16 to rotate to a certain angle through the active pulley 18, drive belt 17, and driven belt ring 161. The top opening of the storage box 20 is vertically facing upwards again, the common plate 26 is in contact with the top of the drive cam 23, the top column 32 is in contact with the top of the inclined section 242 of the end face cam 24, and the two guide plates 25 are in a completely contacted state. The entire processing equipment is restored to the working state of crushable screening.

[0051] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
