Description

Technical Field

[0001] This invention relates to the field of crushing equipment technology, and specifically to a concrete block crushing system. Background Technology

[0002] After concrete processing, some concrete may solidify into blocks if not used promptly. These solidified blocks can generally be crushed and reused as raw materials in new concrete. Current technology typically uses crushing equipment to break up these concrete blocks. However, the blocks may vary in size, leading to splashing during crushing and posing a safety hazard to the area around the crushing equipment. Furthermore, if small particles generated during crushing remain within the crushing equipment, it can increase the workload on the screening and crushing components. Summary of the Invention

[0003] To address the aforementioned technical shortcomings, the present invention aims to provide a concrete block crushing system that prevents splashing during crushing and improves safety.

[0004] To solve the above-mentioned technical problems, the present invention provides a concrete block crushing system, comprising: Vertical crusher; Feeding box; The discharge box, feeding box, and discharge box are respectively installed on the opposite side walls of the vertical crusher; The screening and crushing components are installed inside the discharge box. The vertical crusher includes a casing located between the feeding box and the discharge box. Both the feeding box and the discharge box are connected to the casing. A vertical cylinder is installed on the top of the casing. A rotary motor is installed on the piston rod of the vertical cylinder. A crushing disc is installed on the output shaft of the rotary motor. Multiple pressure plate assemblies are evenly distributed on the outer peripheral wall of the rotary motor. The screening and crushing assembly includes a drive motor installed on the inner wall of the discharge box, a rotating drum installed on the output shaft of the drive motor, multiple feeding slots evenly distributed along the circumference on the outer peripheral wall of the rotating drum, and an electric crushing hammer assembly corresponding to the position of the rotating drum installed at the end of the discharge box away from the machine casing.

[0005] Preferably, the feeding box has an opening slot on the side wall near the machine casing, and the feeding box is connected to the machine casing through the opening slot. An inclined guide plate is provided inside the feeding box. The guide plate has a screen-like structure, and a receiving plate is horizontally movable below the guide plate. After the concrete block is added into the feeding box, the small particles in the concrete block can be screened by the guide plate. The screened small particles pass through the guide plate and fall onto the receiving plate for easy collection. At the same time, the screened concrete block can enter the machine casing through the opening slot for crushing.

[0006] Preferably, the crushing disc is coaxially mounted on the output shaft of the rotating motor, and multiple crushing blades are provided on the circular end face of the crushing disc away from the rotating motor. The rotating motor drives the crushing disc to rotate, thereby crushing the concrete block through the crushing blades.

[0007] Preferably, the rotating motor is externally fixedly fitted with a motor base, which is mounted on the piston rod of the vertical cylinder. The rotating motor is embedded in the bottom of the motor base. Two pressure plate assemblies are provided, and the two pressure plate assemblies are symmetrically arranged on opposite side walls of the motor base. The pressure plate assembly includes: The arc-shaped pressure plate has one end of its arc-shaped opening set on the side wall of the motor base, and the other end of its arc-shaped opening is slidably set on the inner wall of the machine housing. The crushing disc is located between the two arc-shaped pressure plates. The stabilizer bar has one end mounted on the side wall of the motor base and the other end vertically extending through the top surface of the casing. The arc-shaped pressure plate helps to keep the concrete blocks concentrated when they are crushed by the crusher blade, and also reduces or avoids the splashing of concrete blocks during crushing.

[0008] Preferably, a sliding groove is vertically provided on the inner wall of the housing, the arc-shaped opening of the arc-shaped pressure plate faces the sliding groove, and the other end of the arc-shaped opening of the arc-shaped pressure plate is hinged to a secondary arc-shaped plate through a rotating shaft with a torsion spring. A roller is rotatably provided at the end of the secondary arc-shaped plate away from the arc-shaped pressure plate, and the roller is slidably provided in the sliding groove, so that the height can be adjusted by driving the arc-shaped pressure plate up and down in the housing according to the height of the concrete blocks accumulated in the housing through a vertical cylinder.

[0009] Preferably, the loading trough has a fan-shaped structure, and multiple arc-shaped opening slots are spaced apart on the arc-shaped outer periphery of the loading trough. A tilting motor base is provided on the side wall of the discharge box away from the machine casing. A tilting motor is provided on the tilting motor base. A breaker hammer mounting base is provided on the output shaft of the tilting motor. The electric breaker hammer group includes multiple electric breaker hammers arranged side by side on the breaker hammer mounting base. The number of electric breaker hammers is the same as the number of arc-shaped opening slots on the same loading trough, and the position of the electric breaker hammer corresponds one-to-one with the position of the arc-shaped opening slot on the same loading trough. After the concrete block in the machine casing enters the loading trough through the arc-shaped opening slot on the same loading trough, it is convenient to be crushed by the electric breaker hammer.

[0010] Preferably, the side wall of the machine casing near the discharge box is open, and a partition is provided in the opening of the side wall of the machine casing near the discharge box. The partition is provided with multiple material channels that correspond one-to-one with the arc-shaped opening slots, so that the concrete blocks in the machine casing can enter each arc-shaped opening slot through the material channels.

[0011] Preferably, the top of the discharge box is open, and the bottom of the top opening of the discharge box and the bottom of the opening of the side wall of the machine housing are on the same horizontal plane. A pushing cylinder is embedded in the side wall of the machine housing away from the discharge box. A pushing plate is horizontally arranged on the piston rod of the pushing cylinder, and the pushing plate is in contact with the bottom surface inside the machine housing. The pushing cylinder pushes the pushing plate to push the concrete blocks inside the machine housing that have been crushed by the crushing disc into the loading trough.

[0012] The beneficial effects of the present invention are as follows: 1. The present invention sequentially crushes concrete blocks through the crushing disc in the vertical crusher and the electric breaker hammer group in the screening and crushing component, thereby improving the crushing effect; at the same time, when crushing in the vertical crusher, small particles in the concrete blocks can be screened by the guide plate, thereby reducing the burden on the screening and crushing component.

[0013] 2. The pressure plate assembly installed in the machine casing can be positioned by a vertical cylinder according to the different heights of the concrete blocks piled up inside the machine casing when using the crushing disc for crushing. This helps to keep the concrete blocks concentrated and also reduces or avoids the splashing of concrete blocks during crushing, thus improving safety.

[0014] 3. Multiple fan-shaped loading troughs are provided along the circumference of the rotating drum to facilitate the sequential loading of concrete blocks. Simultaneously, the crushing is completed under the action of the electric breaker hammer assembly, which can achieve different crushing effects according to different needs.

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Example 1 like Figure 1 , Figures 3 to 6As shown, the present invention provides a concrete block crushing system, including a vertical crusher 1; a feeding box 2; the feeding box 2 and the discharge box 3 are respectively disposed on opposite side walls of the vertical crusher 1; a screening and crushing assembly 4 is disposed inside the discharge box 3; the vertical crusher 1 includes a housing 11 disposed between the feeding box 2 and the discharge box 3, both of which are connected to the housing 11; a vertical cylinder 12 is disposed on the top of the housing 11; a rotary motor 13 is disposed on the piston rod of the vertical cylinder 12; a crushing disc 14 is disposed on the output shaft of the rotary motor 13; and multiple crushing discs 14 are evenly distributed on the outer peripheral wall of the rotary motor 13. The pressure plate assembly 15; the screening and crushing assembly 4 includes a drive motor 41 installed on the inner wall of the discharge box 3, a rotating drum 42 installed on the output shaft of the drive motor 41, and multiple feeding slots 43 evenly distributed circumferentially on the outer peripheral wall of the rotating drum 42. An electric crushing hammer assembly 44 corresponding to the position of the rotating drum 42 is installed at the end of the discharge box 3 away from the housing 11; the feeding box 2 has an opening slot 22 on the side wall near the housing 11, and the feeding box 2 is connected to the housing 11 through the opening slot 22. A guide plate 21 is inclinedly installed inside the feeding box 2. The guide plate 21 has a screen-like structure, and a receiving plate 23 is horizontally movable below the guide plate 21.

[0025] Concrete blocks are added to the feeding box 2 (the top of the feeding box 2 is open). Small particles in the concrete blocks are screened by the guide plate 21. The screened small particles fall through the guide plate 21 onto the receiving plate 23 for easy collection. At the same time, the screened concrete blocks enter the bottom surface of the machine casing 11 through the opening slot 22. According to the height of the concrete blocks falling to the bottom surface of the machine casing 11, the vertical cylinder 12 is activated to drive the rotating motor 13 and the crushing disc 14 to adjust their positions in the vertical direction. At the same time, the rotating motor 13 is activated to drive the crushing disc 14 to rotate, so that the crushing disc 14 can be used to crush the concrete blocks. When the vertical cylinder 12 drives the rotating motor 13 and the crushing disc 14 to adjust their positions in the vertical direction, the pressure plate assembly 15 can also be adjusted in the vertical direction. This helps to keep the concrete blocks concentrated on the bottom surface of the machine casing 11 and also reduces or avoids the splashing of concrete blocks during crushing.

[0026] The drive motor 41 drives the rotating drum 42 to rotate, so that the concrete blocks crushed by the crushing disc 14 enter the machine casing 11 one by one into each loading trough 43, and then the electric breaker hammer group 44 completes the crushing operation of the concrete blocks in each loading trough 43 in sequence.

[0027] Example 2 Based on Example 1, such as Figure 2 and Figure 4As shown, the crushing disc 14 is coaxially mounted on the output shaft of the rotating motor 13. Multiple crushing blades 141 are provided on the circular end face of the crushing disc 14 away from the rotating motor 13. The rotating motor 13 is externally fixedly fitted with a motor base 16, which is mounted on the piston rod of the vertical cylinder 12. The rotating motor 13 is embedded in the bottom of the motor base 16. Two pressure plate assemblies 15 are provided, and the two pressure plate assemblies 15 are symmetrically arranged on the opposite side walls of the motor base 16. The pressure plate assembly 15 includes an arc-shaped pressure plate 151. One end of the arc-shaped opening of the arc-shaped pressure plate 151 is located on the side wall of the motor base 16, and the other end of the arc-shaped opening of the arc-shaped pressure plate 151 is slidably mounted on the inner wall of the housing 11. The crushing disc 14 is located between the two arc-shaped pressure plates 151. One end of the stabilizing rod 152 is located on the side wall of the motor base 16, and the other end of the stabilizing rod 152 vertically moves through the top surface of the housing 11.

[0028] When the concrete block enters the housing 11, the rotating motor 13 is started to drive the crushing disc 14 to rotate, so that the concrete block can be crushed by the crushing blade 141. According to the height of the concrete block accumulation in the housing 11, the vertical cylinder 12 can drive the motor base 16 and the arc-shaped pressure plate 151 to move up and down in the housing 11 to adjust the height (the other end of the stabilizer 152 can slide in the top surface of the housing 11 at the same time, which helps to keep the moving position of the motor base 16 and the arc-shaped pressure plate 151 stable). The arc-shaped pressure plate 151 can help keep the concrete block concentrated when the concrete block is crushed by the crushing blade 141, and can also reduce or avoid the concrete block from splashing during crushing.

[0029] A vertical groove 111 is provided on the inner wall of the housing 11. The arc-shaped opening of the arc-shaped pressure plate 151 faces the groove 111. The other end of the arc-shaped opening of the arc-shaped pressure plate 151 is hinged to a secondary arc-shaped plate 154 through a rotating shaft 153 with a torsion spring. A roller 155 is rotatably provided at the end of the secondary arc-shaped plate 154 away from the arc-shaped pressure plate 151, and the roller 155 is slidably disposed in the groove 111. When the vertical cylinder 12 drives the motor base 16 and the arc-shaped pressure plate 151 to move up and down in the housing 11 to adjust the height, the roller 155 can move in the groove 111 at the same time. When the secondary arc-shaped plate 154 abuts against the concrete block on the bottom of the housing 11, the secondary arc-shaped plate 154 can rotate with the rotating shaft 153 with a torsion spring as the axis, thereby ensuring that the other end of the arc-shaped opening of the arc-shaped pressure plate 151 continues to move under the push of the vertical cylinder 12.

[0030] Example 3 Based on Example 1, such as Figure 1 , Figures 5 to 6As shown, the loading trough 43 has a fan-shaped structure, and multiple arc-shaped opening slots 431 are spaced apart on the arc-shaped outer periphery of the loading trough 43. A tilting motor base 5 is provided on the side wall of the discharge box 3 away from the housing 11. A tilting motor 51 is provided on the tilting motor base 5. A breaker hammer mounting base 52 is provided on the output shaft of the tilting motor 51. The electric breaker hammer assembly 44 includes multiple electric breaker hammers 441 arranged side by side on the breaker hammer mounting base 52. The number of electric breaker hammers 441 is the same as that of the same loading trough 43. The number of arc-shaped opening slots 431 on the 3 is the same, and the position of the electric breaker hammer 441 corresponds one-to-one with the position of the arc-shaped opening slots 431 on the same loading trough 43; the top of the discharge box 3 is open, and the bottom of the top opening of the discharge box 3 and the side wall opening of the housing 11 are on the same horizontal plane. A pusher cylinder 7 is embedded in the side wall of the housing 11 away from the discharge box 3. A pusher plate 71 is horizontally arranged on the piston rod of the pusher cylinder 7, and the pusher plate 71 is in contact with the bottom surface inside the housing 11.

[0031] The pusher cylinder 7 pushes the pusher plate 71, which allows concrete blocks inside the housing 11 to enter the loading trough 43 through the arc-shaped opening slot 431 on the same loading trough 43. Then, the flip motor 51 drives the breaker mounting base 52 to flip, causing the electric breaker assembly 44 to flip towards the loading trough 43. This allows each breaker head on the electric breaker 441 to be inserted into the corresponding arc-shaped opening slot 431, thereby crushing the concrete blocks in the loading trough 43. After crushing, the drive motor 41 drives the rotating drum 42 to continue rotating, allowing the crushed concrete blocks to be poured out of the loading trough 43. At the same time, it is convenient for other loading troughs 43 to continue to hold concrete blocks.

[0032] The side wall of the casing 11 near the discharge box 3 is open, and a partition 6 is provided in the opening of the side wall of the casing 11 near the discharge box 3. The partition 6 is provided with multiple material channels 61 that correspond one-to-one with the arc-shaped opening slots 431. Concrete blocks can enter the corresponding arc-shaped opening slots 431 from inside the casing 11 through the material channels 61 on the partition 6, which facilitates the feeding of concrete blocks into the loading trough 43.

Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
