Description

Technical Field

[0001] The utility model relates to the technical field of recycled manufactured sand, in particular to a crusher for recycled manufactured sand production. Background Art

[0002] Manufactured sand is a kind of sand mold material for casting, usually composed of quartz sand and binder. Recycled manufactured sand refers to the treatment of used manufactured sand to make it reach a reusable state again. The treatment process of recycled manufactured sand usually includes steps such as crushing, screening, sintering, and degreasing.

[0003] In the existing related technologies, there are often the following defects: when using a crusher to recycle and crush manufactured sand, when the manufactured sand is put into the crusher from the feed inlet for crushing, some of the manufactured sand is likely to pop out due to the impact force in the feed inlet, and the popped manufactured sand may cause harm to workers.

[0004] Therefore, the utility model provides a crusher for recycled manufactured sand production. Content of the Utility Model

[0005] The purpose of the utility model is to solve the defect that in the prior art, manufactured sand is likely to pop out due to the impact force in the feed inlet, and a crusher for recycled manufactured sand production is proposed.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme: a crusher for recycled manufactured sand production, including a crusher body, a feed inlet is arranged on the surface of the crusher body, a conveyor belt is installed on the surface of the crusher body, and a shielding structure is arranged on the surface of the crusher body. The shielding structure includes a bracket, the bracket is fixedly connected to the surface of the crusher body, a rectangular plate is rotatably connected to the inner wall of the bracket, a traction belt is fixedly connected to one side of the rectangular plate, a baffle is slidably inserted on the surface of the crusher body, one side of the baffle is fixedly connected to the traction belt, and two springs are fixedly connected to the surface of the baffle. Both of the two springs are fixedly connected to the surface of the crusher body.

[0007] The effects achieved by the above components are as follows: by setting the shielding structure, it is convenient to shield the feed inlet, thus avoiding the situation that when the manufactured sand is put into the crusher from the feed inlet for crushing, some of the manufactured sand is likely to pop out due to the impact force in the feed inlet, and further playing a role in protecting workers from being injured during the recycled processing of manufactured sand.

[0008] Preferably, two round rods penetrate through the baffle plate in a sliding manner, the round rods penetrate through the springs, and a round block is fixedly connected to the end of the round rod far away from the crusher body.

[0009] The effects achieved by the above components are as follows: When the baffle moves, it will slide along the surface of the round rod. After the baffle moves to a suitable position, the round block at one end of the round rod will restrict the baffle to prevent the baffle from disengaging from the crusher body.

[0010] Preferably, a plurality of protective pads are fixedly connected to one side of the baffle, and the protective pads are made of rubber.

[0011] The effects achieved by the above components are as follows: After the baffle moves to a suitable position, it will drive the protective pads to closely fit against the inner wall of the feeding port. The protective pads play a role in preventing the baffle from hitting the inner wall of the feeding port and being damaged when it is reset by the spring.

[0012] Preferably, a plurality of anti-slip grooves are formed on the surface of the rectangular plate, and all the anti-slip grooves are "V"-shaped.

[0013] The effects achieved by the above components are as follows: The anti-slip grooves on the surface of the rectangular plate increase the friction force, preventing workers from slipping when stepping on the surface when there is machine-made sand scattered on the surface of the rectangular plate.

[0014] Preferably, an adjusting structure is provided on the surface of the crusher body. The adjusting structure includes an extension plate fixedly connected to the surface of the crusher body. A threaded rod passes through the extension plate in a threaded manner, and a pressing block is rotatably connected to one end of the threaded rod close to the conveyor belt.

[0015] The effects achieved by the above components are as follows: By setting the adjusting structure, it is convenient to adjust the tightness of the conveyor belt on the crusher body, so that the conveyor belt is tightened on the surface of the crusher body, thereby improving the conveying effect of the conveyor belt.

[0016] Preferably, a groove is formed on the surface of the pressing block, and a rotating wheel is rotatably connected to the inner wall of the groove.

[0017] The effects achieved by the above components are as follows: When the conveyor belt moves, it will slide along the surface of the rotating wheel, and the rotating wheel will rotate in the groove. The rotating wheel plays a role in reducing the friction force between the conveyor belt and the pressing block, thereby preventing excessive friction and wear when the conveyor belt moves on the surface of the pressing block.

[0018] Preferably, a limiting rod slidably passes through the extension plate, and the limiting rod is fixedly connected to the surface of the pressing block.

[0019] The effects achieved by the above components are as follows: When the pressing block moves, it will drive the limiting rod to slide in the extension plate. The extension plate restricts the moving path of the limiting rod, and further restricts the moving path of the pressing block, preventing the pressing block from rotating when it moves.

[0020] Preferably, a turntable is fixedly connected to one end of the threaded rod away from the pressing block, and the cross-section of the turntable is in the shape of a "plus" sign.

[0021] The effects achieved by the above components are as follows: the rotation of the turntable drives the rotation of the threaded rod, and the turntable serves to facilitate the rotation of the threaded rod.

[0022] In summary:

[0023] 1. In the present utility model, by providing a shielding structure, the rectangular plate rotates within the bracket by virtue of the gravity of the worker stepping on it. The rotation of the rectangular plate pulls the traction belt to move, and the movement of the traction belt drives the baffle to move. The baffle slides within the crusher body during movement, and the spring is stretched when the baffle moves. When the baffle moves to an appropriate position, the feeding port is in an open state at this time, so that the machine-made sand can be poured into the crusher body for crushing. When the worker moves from the surface of the rectangular plate, the baffle is reset by the force of the spring contraction, and the baffle covers the feeding port, thus avoiding the splashing of the machine-made sand from the feeding port when using the crusher body to crush the machine-made sand.

[0024] 2. In the present utility model, by providing an adjustment structure, the threaded rod is rotated. The rotation of the threaded rod causes it to move within the extension plate by means of the thread. The movement of the threaded rod drives the pressing block to move towards the conveyor belt. When the pressing block moves to an appropriate position, the pressing block squeezes the conveyor belt, and the conveyor belt is gradually tightened on the surface of the crusher body under the extrusion of the pressing block, thereby improving the conveying effect of the conveyor belt.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0031] Refer to Figure 1 As shown, the utility model provides a technical solution: a crusher for producing recycled manufactured sand, which includes a crusher body 1. A feed inlet 2 is provided on the surface of the crusher body 1. A conveyor belt 3 is installed on the surface of the crusher body 1. A shielding structure 4 is provided on the surface of the crusher body 1. By setting the shielding structure 4, it is convenient to shield the feed inlet 2, so as to avoid the situation that when part of the manufactured sand is easily ejected by the impact force in the feed inlet 2 when the manufactured sand is put into the crusher through the feed inlet 2 for crushing, thereby ensuring that workers are not injured during the recycling process of the manufactured sand. An adjusting structure 5 is provided on the surface of the crusher body 1. By setting the adjusting structure 5, it is convenient to adjust the tightness of the conveyor belt 3 on the crusher body 1, so that the conveyor belt 3 is tightened on the surface of the crusher body 1, thereby improving the conveying effect of the conveyor belt 3.

[0032] Next, specifically describe the specific settings and functions of its shielding structure 4 and adjusting structure 5.

[0033] Refer to Figure 2 and Figure 3 With Figure 4 As shown, in this implementation: The shielding structure 4 includes a bracket 41, the bracket 41 is fixedly connected to the surface of the crusher body 1. A rectangular plate 42 is rotatably connected to the inner wall of the bracket 41. One side of the rectangular plate 42 is fixedly connected to a traction belt 43. A baffle 44 is slidably inserted on the surface of the crusher body 1. One side of the baffle 44 is fixedly connected to the traction belt 43. Two springs 45 are fixedly connected to the surface of the baffle 44, and both springs 45 are fixedly connected to the surface of the crusher body 1. Two round rods 46 penetrate through the surface of the baffle 44, the round rods 46 penetrate through the springs 45, and a round block 47 is fixedly connected to the end of the round rod 46 away from the crusher body 1. The baffle 44 will slide along the surface of the round rod 46 when moving. When the baffle 44 moves to a suitable position, the round block 47 at one end of the round rod 46 will limit the baffle 44 to prevent the baffle 44 from coming out of the crusher body 1. A plurality of protective pads 48 are fixedly connected to one side of the baffle 44. The protective pads 48 are made of rubber. After the baffle 44 moves to a suitable position, it will drive the protective pads 48 to closely fit the inner wall of the feed inlet 2. The protective pads 48 play a role in preventing the baffle 44 from hitting the inner wall of the feed inlet 2 and being damaged when resetting by means of the spring 45. A plurality of anti-slip grooves 49 are provided on the surface of the rectangular plate 42. All the anti-slip grooves 49 are "V"-shaped. The anti-slip grooves 49 on the surface of the rectangular plate 42 play a role in increasing the friction force and preventing workers from slipping when stepping on the surface when there is manufactured sand on the surface of the rectangular plate 42.

[0034] Refer to Figure 5As shown in the figure, specifically, the adjusting structure 5 includes an extension plate 51, which is fixedly connected to the surface of the crusher body 1. A threaded rod 52 penetrates through the surface of the extension plate 51. One end of the threaded rod 52 close to the conveyor belt 3 is rotatably connected to a pressing block 53. A groove 54 is formed on the surface of the pressing block 53, and a rotating wheel 55 is rotatably connected to the inner wall of the groove 54. When the conveyor belt 3 moves, it will slide along the surface of the rotating wheel 55, and the rotating wheel 55 will rotate in the groove 54. The rotating wheel 55 serves to reduce the friction between the conveyor belt 3 and the pressing block 53, thereby avoiding excessive friction when the conveyor belt 3 moves on the surface of the pressing block 53 and causing wear. A limiting rod 56 penetrates through the surface of the extension plate 51 in a sliding manner, and the limiting rod 56 is fixedly connected to the surface of the pressing block 53. When the pressing block 53 moves, it will drive the limiting rod 56 to slide in the extension plate 51. The extension plate 51 serves to limit the movement path of the limiting rod 56, and further limit the movement path of the pressing block 53, avoiding the rotation of the pressing block 53 when it moves. One end of the threaded rod 52 away from the pressing block 53 is fixedly connected to a turntable 57. The cross-section of the turntable 57 is in the shape of a "plus" sign. Rotating the turntable 57 will drive the threaded rod 52 to rotate. The turntable 57 serves to facilitate the rotation of the threaded rod 52.

[0035] Working principle: When it is necessary to crush the machine-made sand, first start the crusher body 1, and then the worker shovels up the machine-made sand and pours it into the feeding port 2. When the worker pours the machine-made sand, they will move towards the direction close to the crusher body 1. When the worker moves to a suitable position to pour, they will step on the surface of the rectangular plate 42. The anti-slip grooves 49 on the surface of the rectangular plate 42 serve to increase the friction force, avoiding the worker slipping when stepping on the surface when there is machine-made sand scattered on the surface of the rectangular plate 42. The rectangular plate 42 will rotate in the support 41 by virtue of the gravity of the worker's stepping. The rotation of the rectangular plate 42 will pull the traction belt 43 to move. The movement of the traction belt 43 will drive the baffle 44 to move. The movement of the baffle 44 will slide in the crusher body 1. When the baffle 44 moves, the spring 45 will be stretched. At this time, the spring 45 is in a stretched state. The baffle 44 will slide along the surface of the round rod 46 when it moves. When the baffle 44 moves to a suitable position, the round block 47 at one end of the round rod 46 will limit the baffle 44 to prevent the baffle 44 from coming out of the crusher body 1. When the baffle 44 moves to a suitable position, at this time the feeding port 2 is in an open state, so that the machine-made sand can be poured into the crusher body 1 for crushing. When the worker moves away from the surface of the rectangular plate 42, the baffle 44 will move in the opposite direction by virtue of the contracting force of the spring 45. After the baffle 44 moves to a suitable position, it will drive the protective pad 48 to closely fit the inner wall of the feeding port 2. The protective pad 48 serves to prevent the baffle 44 from hitting the inner wall of the feeding port 2 and being damaged when it is reset by the spring 45. At this time, the baffle 44 will cover the feeding port 2, thereby avoiding the machine-made sand splashing out of the feeding port 2 when using the crusher body 1 to crush the machine-made sand.

[0036] When it is necessary to adjust the tightness of the conveyor belt 3, first rotate the turntable 57. The rotation of the turntable 57 will drive the rotation of the threaded rod 52. The rotation of the threaded rod 52 will cause it to move within the extension plate 51 by means of the thread. The movement of the threaded rod 52 will drive the pressing block 53 to move towards the conveyor belt 3. When the pressing block 53 moves, it will drive the limiting rod 56 to slide within the extension plate 51. The extension plate 51 restricts the movement path of the limiting rod 56, and thus restricts the movement path of the pressing block 53, playing the role of preventing the pressing block 53 from rotating when it moves. After the pressing block 53 moves to an appropriate position, the pressing block 53 will drive the runner 55 to squeeze the conveyor belt 3. The conveyor belt 3 will be gradually tightened on the surface of the crusher body 1 under the extrusion of the runner 55, thereby improving the conveying effect of the conveyor belt 3. When the conveyor belt 3 moves, it will slide along the surface of the runner 55, and the runner 55 will rotate within the groove 54. The runner 55 plays the role of reducing the friction between the conveyor belt 3 and the pressing block 53, thus preventing excessive friction from causing wear when the conveyor belt 3 moves on the surface of the pressing block 53.
