Description

Technical Field

[0001] This utility model belongs to the field of crushing and sorting technology of waste buildings and structures, specifically a crushing and sorting device for waste buildings and structures. Background Technology

[0002] Crushing equipment: Machinery that uses mechanical force to crush solid materials into small pieces, fine powder, or pulverized powder. The characteristics of crushing operations using crushing machinery include high energy consumption, large quantities of wear-resistant materials and grinding media, severe dust generation, and high noise levels. Sorting equipment is an important piece of equipment in solid waste treatment; its purpose is to separate recyclable or unsuitable substances from solid waste for subsequent treatment and disposal processes.

[0003] Meanwhile, application number CN218107969U, entitled "A Waste Building Structure Crushing and Sorting Equipment," describes a waste building structure crushing and sorting equipment that includes a screening plate. An iron plate is fixedly connected to the upper side of the screening plate, and screening holes are formed on the surface of the iron plate. Two support frames are slidably connected to both the front and rear ends of the screening plate. A motor is fixedly connected to the right side of the iron plate, and a turntable is fixedly connected to the output end of the motor. A connecting rod is fixedly connected to the rear edge of the turntable, and a rotating rod is rotatably connected to the rear end of the connecting rod. A cylinder is rotatably connected inside the rotating rod, and the front side of the cylinder is fixedly connected to the rear side of the screening plate. The screening plate is equipped with a screening hole adjustment device and a screening hole size fixing device. This waste building structure crushing and sorting equipment allows for the adjustment of the screening hole size by rotating a handle, thereby screening the crushed structures according to their size as needed, facilitating the classified collection of waste building structures.

[0004] The above-mentioned technical solution has the following drawbacks during use: because abandoned buildings contain waste metals, wood, plastic products, and concrete, these materials can easily damage or accumulate on the screening plate when it is used for a long time. Furthermore, the device cannot disassemble, replace, or clean the screening plate, which affects the sorting effect of the abandoned buildings and makes the sorting efficiency of the abandoned buildings worse. In addition, a large amount of abandoned buildings will clog the screening plate, affecting the sorting efficiency of the subsequent abandoned buildings.

[0005] Therefore, a crushing and sorting device for abandoned buildings and structures is proposed to address the above problems. Utility Model Content

[0006] To address the problems mentioned in the background art, this utility model provides a crushing and sorting device for waste building structures, which has the advantages of being able to disassemble and process screen plates that are damaged or have accumulated large amounts of waste building materials, thereby replacing the damaged screen plates and facilitating the cleaning of accumulated waste building materials.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a crushing and sorting device for waste building structures, including a processing frame, a crushing mechanism installed on the surface of the processing frame, a sorting plate provided on the surface of the processing frame, and a disassembly and replacement component installed on the surface of the processing frame;

[0008] The disassembly and replacement assembly includes a support plate. The support plate is symmetrically mounted on the surface of the processing frame. Disassembly blocks are symmetrically arranged on the surface of the sorting plate. The support plate has a positioning groove adapted to the disassembly block. The support plate and the sorting plate are slidably connected through the disassembly block and the positioning groove. A disassembly rod is slidably connected in a through hole on the surface of the support plate. One end of the disassembly rod passes through the support plate and is inserted into a hole on the surface of the disassembly block. An adjustment block is mounted on the surface of the disassembly block. The disassembly block is slidably connected in a groove on the surface of the sorting plate through the adjustment block. A drive disassembly assembly is mounted on the surface of the sorting plate.

[0009] Preferably, a guide rod is slidably connected in the through hole on the surface of the adjusting block, and both ends of the guide rod pass through the adjusting block and are installed in the groove on the surface of the sorting plate.

[0010] Preferably, a return spring is sleeved on the surface of the guide rod, one end of the return spring is connected to the adjusting block, and the other end of the return spring is installed in a groove opened on the surface of the sorting plate.

[0011] Preferably, a second return spring is sleeved on the surface of the disassembly rod, one end of the second return spring is connected to the disassembly rod, and the other end of the second return spring is connected to the support plate.

[0012] Preferably, the drive disassembly assembly includes a drive mechanism, the drive mechanism is mounted on the surface of the support plate, a connecting plate is mounted on the pull rod of the drive mechanism, a fixing block is mounted on the side surface of the connecting plate near the sorting plate, an mounting block is mounted on one side surface of the sorting plate, and the fixing block is inserted into the interior of the mounting block.

[0013] Preferably, a threaded rod is slidably connected in a through hole on the surface of the mounting block, one end of which passes through the mounting block and the fixing block in sequence and extends to the bottom of the mounting block.

[0014] Preferably, both ends of the threaded rod are threaded with nuts, which fit against the surface of the mounting block.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. This utility model incorporates a disassembly and replacement component. Since building structures contain waste metal, wood, plastic products, and concrete, the sorting plate will be damaged over time as the crushed materials continuously fall onto it. The operator first pulls the disassembly rod, which causes the second return spring to deform and reset its position, facilitating operation. During the pulling process, one end of the disassembly rod disengages from the insertion hole on the surface of the disassembly block. The operator then pulls the sorting plate, causing the disassembly block to slide in the positioning groove on the support plate. Once the disassembly block disengages from the positioning groove, the sorting plate can be disassembled. This allows for the replacement and cleaning of damaged sorting plates or large accumulations of building material impurities, further improving the sorting efficiency of subsequent building materials.

[0017] 2. This utility model incorporates a drive disassembly assembly. When disassembling the sorting plate, the nut is first rotated to disengage from the surface of the threaded rod. Then, the threaded rod is pulled to disengage from the mounting block and the fixing block. The threaded rod secures the positions of the fixing block and the mounting block, preventing the drive mechanism from separating from the sorting plate during use. The drive mechanism then drives the connecting plate, causing the connecting plate to disengage the fixing block from the interior of the mounting block, thereby separating the drive mechanism from the sorting plate and facilitating the disassembly of the sorting plate.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1 to 5 As shown, this utility model provides a crushing and sorting device for waste building structures, including a processing frame 1, a crushing mechanism 12 installed on the surface of the processing frame 1, a sorting plate 13 provided on the surface of the processing frame 1, and a disassembly and replacement component 2 installed on the surface of the processing frame 1.

[0026] The disassembly and replacement assembly 2 includes a support plate 21. The support plate 21 is symmetrically mounted on the surface of the processing frame 1. The disassembly blocks 22 are symmetrically arranged on the surface of the sorting plate 13. The surface of the support plate 21 is provided with a positioning groove 23 that matches the disassembly block 22. The support plate 21 and the sorting plate 13 are slidably connected through the disassembly block 22 and the positioning groove 23. A disassembly rod 24 is slidably connected in a through hole on the surface of the support plate 21. One end of the disassembly rod 24 passes through the support plate 21 and is inserted into a hole on the surface of the disassembly block 22. An adjustment block 25 is mounted on the surface of the disassembly block 22. The disassembly block 22 is slidably connected in a groove on the surface of the sorting plate 13 through the adjustment block 25. The surface of the sorting plate 13 is provided with a drive disassembly assembly 3.

[0027] Specifically, such as Figure 1 As shown, a guide rod 26 is slidably connected in the through hole on the surface of the adjusting block 25. Both ends of the guide rod 26 pass through the adjusting block 25 and are installed in the groove on the surface of the sorting plate 13. A return spring 27 is sleeved on the surface of the guide rod 26. One end of the return spring 27 is connected to the adjusting block 25, and the other end of the return spring 27 is installed in the groove on the surface of the sorting plate 13. A return spring 28 is sleeved on the surface of the disassembly rod 24. One end of the return spring 28 is connected to the disassembly rod 24, and the other end of the return spring 28 is connected to the support plate 21.

[0028] In this implementation plan: when crushing building structures, the building structures are first poured into the crushing mechanism 12. Then the crushing mechanism 12 is started to crush the building structures. After crushing, the crushed building structures fall onto the sorting plate 13 for sorting.

[0029] When sorting the crushed building structures, the drive mechanism 31 is activated, which moves the sorting plate 13. During the movement, the sorting plate 13 slides on the surface of the adjusting block 25 installed on the surface of the disassembly block 22 through the sliding groove on its surface. At this time, the guide rod 26 in the sliding groove on the surface of the sorting plate 13 slides inside the adjusting block 25. The guide rod 26 can guide the movement of the sorting plate 13 and prevent the sorting plate 13 from shifting position during movement. When the sorting plate 13 presses the return spring 27 during the sliding process, the return spring 27 deforms under pressure and can reset the movement of the sorting plate 13, thereby greatly improving the efficiency of the device during use.

[0030] Because the building structures contain waste metal, wood, plastic products, and concrete, the sorting plate 13 will be damaged after prolonged use as the crushed building structures continuously fall onto it. In this case, the operator first pulls the dismantling rod 24, which causes the return spring 28 to deform. The return spring 28 resets the position of the dismantling rod 24, making it easier for the operator to use. During the pulling of the dismantling rod 24, one end of the dismantling rod 24 disengages from the insertion hole on the surface of the dismantling block 22. Then, the operator pulls the sorting plate 13, causing the dismantling block 22 to slide in the positioning groove 23 on the surface of the support plate 21. Once the dismantling block 22 disengages from the positioning groove 23, the sorting plate 13 can be dismantled. This allows for the replacement and cleaning of damaged sorting plates 13 or large accumulations of building structure impurities, further improving the sorting efficiency of subsequent building structures.

[0031] Please refer to Example 2 Figures 1-5 The difference between this embodiment and embodiment 1 is that the drive disassembly assembly 3 includes a drive mechanism 31, the drive mechanism 31 is mounted on the surface of the support plate 21, a connecting plate 32 is mounted on the pull rod of the drive mechanism 31, a fixing block 33 is mounted on the side surface of the connecting plate 32 near the sorting plate 13, an mounting block 34 is mounted on one side surface of the sorting plate 13, and the fixing block 33 is inserted into the interior of the mounting block 34.

[0032] Specifically, such as Figure 1-5 As shown, a threaded rod 35 is slidably connected in the through hole opened on the surface of the mounting block 34. One end of the threaded rod 35 passes through the mounting block 34 and the fixing block 33 in sequence and extends to the bottom of the mounting block 34. Both ends of the threaded rod 35 are threadedly connected with nuts 36, which fit against the surface of the mounting block 34.

[0033] In this implementation scheme: when disassembling the sorting plate 13, first rotate the nut 36 so that the nut 36 disengages from the surface of the threaded rod 35. Then pull the threaded rod 35 so that the threaded rod 35 disengages from the mounting block 34 and the fixing block 33. The threaded rod 35 can fix the position of the fixing block 33 and the mounting block 34, preventing the drive mechanism 31 from separating from the sorting plate 13 during use. At this time, the drive mechanism 31 drives the connecting plate 32, so that the connecting plate 32 drives the fixing block 33 to disengage from the inside of the mounting block 34, thereby realizing the separation of the drive mechanism 31 from the sorting plate 13, which facilitates the disassembly of the sorting plate 13.

[0034] It should be noted that the drive mechanism 31 in this device is a mature existing technology and works on the same principle as the published patent CN218107969U, "A Waste Building Structure Crushing and Sorting Equipment". For specific operation, please refer to the published patent. Both involve moving the sorting plate 13 through structures such as turntables and pull rods.

[0035] The structures (such as electric motors) are existing technology and will not be described in detail. Additionally, this invention also includes a power supply, controller, and switches, which are not the main technical points of this patent and will not be described in detail. The wiring diagram of the motor in this invention is common knowledge in the field, and its working principle is already known technology. The appropriate model is selected based on actual use; therefore, the control method and wiring layout of the motor will not be explained in detail.

[0036] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
