Description

Technical Field

[0001] This utility model relates to a concrete recycled aggregate preparation device, specifically a concrete recycled aggregate preparation device, belonging to the technical field of building material production equipment. Background Technology

[0002] Construction waste, such as discarded concrete blocks, generated during building construction can lead to resource waste and environmental pressure if not properly disposed of. Converting it into recycled aggregate is an important way to achieve the resource utilization of construction waste. In the crushing stage, jaw crushers are commonly used equipment. A jaw crusher has a moving jaw and a fixed jaw, both equipped with jaw plates. During the reciprocating motion of the moving jaw, the jaw plates continuously impact the material to be crushed, thereby breaking the material.

[0003] However, the jaw plates of traditional jaw crushers are of a one-piece structure. Over long-term use, due to continuous impact and friction with the material, the jaw plates are prone to localized damage. Because of this one-piece design, once a part is damaged, the entire jaw plate needs to be replaced, significantly increasing operating costs and hindering the economical and efficient operation of the equipment. Utility Model Content

[0004] The purpose of this invention is to provide a concrete recycled aggregate preparation device to solve the above problems. When a part of the jaw plate is damaged, it is not necessary to replace the entire jaw plate. Only the damaged part needs to be replaced. This design greatly reduces the replacement cost of the jaw plate, improves the maintenance efficiency of the equipment, and makes the concrete recycled aggregate preparation device more economical and practical in long-term operation, better meeting the needs of efficient and low-cost operation of equipment in the production process of building materials.

[0005] This utility model achieves the above-mentioned objective through the following technical solution: a concrete recycled aggregate preparation device, comprising a jaw crusher body, wherein connecting seats are fixedly connected to both the moving jaw and the fixed jaw of the jaw crusher body, a movable seat is slidably connected to the connecting seat, four clamping seats are fixedly connected to the movable seat, four jaw plates are provided on one side of the movable seat, one side of the jaw plate is slidably connected to two clamping seats, adjacent jaw plates abut against each other, and the jaw plates abut against the connecting seats. A fixing structure is provided on the movable seat, the fixing structure including clamping plates and clamping blocks, clamping plates are slidably connected to the movable seat, one end of the clamping plate is engaged with the connecting seat, two clamping blocks are slidably connected to the movable seat, one end of the clamping blocks is engaged with the clamping plate, two connecting columns are fixedly connected to the movable seat, the connecting columns pass through adjacent clamping blocks, and knobs are threadedly connected to the connecting columns, the knobs abut against the clamping blocks.

[0006] Preferably, the overall cross-section of the card plate is L-shaped, and the cross-section of the card plate near the connecting seat is trapezoidal.

[0007] Preferably, the card block has a waist groove, and the cross-section of the card block near the card plate is trapezoidal.

[0008] Preferably, the card block is provided with a card slot, and one end of the knob engages with the card slot.

[0009] Preferably, the cross-section of the card holder is trapezoidal, and the sliding direction of the movable seat on the connecting seat and the sliding direction of the jaw plate on the card holder are perpendicular to each other.

[0010] Preferably, a support base is fixedly connected to the jaw crusher body, a rotating base is rotatably connected to the support base, and a guide hopper is fixedly connected to the rotating base.

[0011] Preferably, the support base is provided with a limiting structure, the limiting structure including a long shaft and a limiting block, the long shaft is rotatably connected to the support base, two limiting blocks are threadedly connected to the long shaft, the limiting blocks are engaged with the rotating base, the limiting blocks are slidably connected to the guide block, and the guide block is fixedly connected to the support base.

[0012] Preferably, the two threaded grooves on the long shaft have opposite thread directions, and a rotating rod is fixedly connected to the long shaft.

[0013] Preferably, the jaw crusher body is provided with multiple mounting holes, and the cross-section of the mounting holes is circular.

[0014] The beneficial effects of this utility model are as follows: When one of the jaw plates is damaged during use, the knob can be rotated. As the knob rotates, it moves away from the locking block. After the knob moves a certain distance, it can push the locking block to slide on the moving seat. When one end of the locking block is no longer engaged with the locking plate, the pushing of the locking block is stopped. Through the above operation, both locking blocks are not engaged with the locking plate. Then, the locking plate can be pulled to prevent it from engaging with the connecting seat. Next, the moving seat can be pulled out from inside the connecting seat. After the moving seat is pulled out, since there is no connecting seat to support one side of the jaw plate, it is only necessary to pull the damaged jaw plate to disengage it from the two locking seats. Then, the new jaw plate can be inserted. The plate is pushed onto two mounting brackets and pushed to make it abut against the adjacent jaw plates. Then, the moving seat is moved to slide into the interior of the connecting seat until one side of the moving seat abuts against the connecting seat. The mounting plate can then be locked against the connecting seat again. At this point, the moving seat cannot move, and multiple jaw plates also cannot move, thus enabling the replacement of the damaged jaw plate. Since only the damaged jaw plate needs to be replaced, instead of replacing the entire plate, the replacement cost of the jaw plates is greatly reduced, the maintenance efficiency of the equipment is improved, and the concrete recycled aggregate preparation device is more economical and practical in long-term operation, better meeting the needs of efficient and low-cost operation of equipment in the production process of building materials.

[0022] 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.

[0023] Please see Figures 1-6 As shown, a concrete recycled aggregate preparation device includes a jaw crusher body 1. Connecting seats 2 are fixedly connected to both the moving jaw and the fixed jaw of the jaw crusher body 1. A movable seat 3 is slidably connected to the connecting seat 2. Four clamping seats 4 are fixedly connected to the movable seat 3. Four jaw plates 5 are provided on one side of the movable seat 3. One side of each jaw plate 5 is slidably connected to two clamping seats 4. Adjacent jaw plates 5 abut against each other, and the jaw plates 5 abut against the connecting seats 2. A fixing structure 6 is provided on the movable seat 3. The fixed structure 6 includes a locking plate 601 and locking blocks 602. The locking plate 601 is slidably connected to the movable base 3, and one end of the locking plate 601 is engaged with the connecting base 2. Two locking blocks 602 are slidably connected to the movable base 3, and one end of the locking blocks 602 is engaged with the locking plate 601. Two connecting posts 605 are fixedly connected to the movable base 3. The connecting posts 605 pass through adjacent locking blocks 602. A knob 606 is threadedly connected to the connecting posts 605, and the knob 606 abuts against the locking blocks 602.

[0024] As a technical optimization of this utility model, the overall cross-section of the card plate 601 is L-shaped, which makes it easy to pull the card plate 601. The cross-section of the card plate 601 near the connecting seat 2 is trapezoidal, which can play a guiding role when the card plate 601 and the connecting seat 2 are engaged.

[0025] As a technical optimization of this utility model, the locking block 602 is provided with a waist groove 603, which allows the connecting column 605 to move inside the waist groove 603, thereby limiting the movement range of the locking block 602. The cross-section of the locking block 602 near the locking plate 601 is trapezoidal, which can play a guiding role when the locking block 602 and the locking plate 601 are engaged.

[0026] As a technical optimization of this utility model, the card block 602 is provided with a card slot 604, and the card block 602 can be fixed by engaging one end of the knob 606 with the card slot 604.

[0027] As a technical optimization of this utility model, the cross-section of the card seat 4 is trapezoidal, which can prevent the jaw plate 5 and the card seat 4 from separating. The sliding direction of the moving seat 3 on the connecting seat 2 and the sliding direction of the jaw plate 5 on the card seat 4 are perpendicular to each other.

[0028] As a technical optimization of this utility model, a support base 8 is fixedly connected to the jaw crusher body 1, a rotating base 9 is rotatably connected to the support base 8, and a guide hopper 10 is fixedly connected to the rotating base 9. The guide hopper 10 can guide the material to be crushed, so that the material can flow accurately between the two connecting bases 2.

[0029] As a technical optimization of this utility model, the support base 8 is provided with a limiting structure 7, which includes a long shaft 701 and a limiting block 702. The long shaft 701 is rotatably connected to the support base 8, and two limiting blocks 702 are threadedly connected to the long shaft 701. The limiting block 702 can be engaged with the rotating seat 9 to prevent the guide hopper 10 from rotating. The limiting block 702 is engaged with the rotating seat 9, and the limiting block 702 is slidably connected to the guide block 703. Therefore, the limiting block 702 can be guided by the guide block 703. The guide block 703 is fixedly connected to the support base 8.

[0030] As a technical optimization of this utility model, the two threaded grooves on the long shaft 701 have opposite thread directions, so when the long shaft 701 rotates in one direction, the two limiting blocks 702 can move in opposite directions. A rotating rod 704 is fixedly connected to the long shaft 701, so the long shaft 701 can be easily rotated by holding the rotating rod 704.

[0031] As a technical optimization of this utility model, the jaw crusher body 1 is provided with a plurality of mounting holes 11, which can be used to install and fix the jaw crusher body 1. The cross-section of the mounting holes 11 is circular.

[0032] In use, this invention guides the material through the guide hopper 10, ensuring that the material to be crushed falls precisely into the two connecting seats 2. During the reciprocating motion of the jaw crusher body 1, the moving jaw drives one of the connecting seats 2. The four jaw plates 5 on one of the connecting seats 2 move synchronously with it, thus repeatedly impacting the material. Combined with the multiple jaw plates 5 on the other connecting seat 2, this achieves material crushing. If one of the jaw plates 5 is damaged during use, the long shaft 701 can be rotated by hand using the rotating rod 704. Unidirectional rotation of the long shaft 701 will threadedly drive the two limit blocks 702 to move in opposite directions. The guide block 703 guides the movement of the limiting block 702. When neither limiting block 702 is engaged with the rotating seat 9, the rotating seat 9 can be rotated. The rotating seat 9 drives the guide hopper 10 to move away from the connecting seat 2. This rotation continues until the guide hopper 10 no longer blocks the connecting seat 2. Then, by rotating the knob 606, the knob 606 moves away from the locking block 602. After the knob 606 moves a certain distance, it can push the locking block 602 to slide on the moving seat 3. When one end of the locking block 602 is no longer engaged with the locking plate 601, the pushing of the locking block 602 stops. Through the above operations, neither locking block 602 is engaged with the locking plate 601. Then, pull the locking plate 601 to disengage it from the connecting seat 2. Next, pull the movable seat 3 out of the connecting seat 2. After the movable seat 3 is pulled out, since there is no connecting seat 2 to block one side of the jaw plate 5, simply pull the damaged jaw plate 5 to disengage it from the two locking seats 4. Next, insert the new jaw plate 5 into the two locking seats 4 and push it to make it abut against the adjacent jaw plate 5. Then, move the movable seat 3 to slide it into the connecting seat 2 until one side of the movable seat 3 abuts against the connecting seat 2. Then, the locking plate 601 can be locked back into the connecting seat 2. Then, push the locking block 602 towards the locking plate 601. When the locking block 602 engages with the locking plate... After the plates 601 engage, the knob 606 can be rotated to engage one end with the slot 604. At this time, the locking block 602 cannot move. Repeat the above operation to engage the other locking block 602 with the locking plate 601. At this time, the moving seat 3 cannot move, and multiple jaw plates 5 also cannot move, thus realizing the replacement of the damaged jaw plate 5. Since only the damaged jaw plate 5 needs to be replaced, instead of replacing the whole plate, the replacement cost of the jaw plate 5 is greatly reduced, the maintenance efficiency of the equipment is improved, and the concrete recycled aggregate preparation device is more economical and practical in long-term operation, better meeting the needs of efficient and low-cost operation of equipment in the production process of building materials.
