A circular machine mechanism sand production is with crushing and grinding equipment

Abstract

This utility model relates to the field of manufactured sand production technology, and in particular to a crushing and grinding equipment for producing circular manufactured sand. It includes a controller fixedly installed on the surface of the housing, a hopper fixedly installed in the middle of the top of the housing, and dust collection boxes fixedly installed on both sides of the top of the housing. Through the two partitions, when raw materials are poured into the hopper, they come into contact with the partitions. The partitions are compressed by the downward force of the raw materials, allowing the elastic seat to deform and open, thus allowing the raw materials to enter the housing for crushing. After all the material has been discharged, the elastic seat returns to its original shape, allowing the two partitions to close again. This prevents dust generated during crushing from escaping from the hopper. Simultaneously, a fan draws the dust into the dust collection boxes, where it is adsorbed onto the filter plates, further preventing dust from spreading and avoiding harm to the human body.

Description

Technical Field

[0001] This utility model relates to the field of manufactured sand production technology, and in particular to a crushing and grinding equipment for producing circular manufactured sand. Background Technology

[0002] Manufactured sand refers to sand processed by sand making machines and other auxiliary equipment. The finished product is more regular and can be processed into sand of different shapes and sizes according to different process requirements, better meeting daily needs. However, the production process requires crushing and grinding the raw sand and gravel. Existing manufactured sand preparation equipment requires a separate screening device after crushing to screen the raw materials, resulting in a large workload for workers and a significant time expenditure, leading to low production efficiency. Furthermore, it is inconvenient to classify and transport the screened raw materials, making it easy for the two types of materials to mix during feeding. Additionally, the dust generated during raw material crushing is easily released into the air, causing harm to human health. Therefore, we propose a circular crushing and grinding equipment for manufactured sand production to solve the above problems. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of the prior art by proposing a crushing and grinding equipment for the production of circular manufactured sand.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a crushing and grinding equipment for producing circular manufactured sand, comprising a box, a controller, a hopper, a dust collector, a first conveyor belt, and a second conveyor belt. The controller is fixedly installed on the surface of the box, the hopper is fixedly installed in the middle of the top of the box, the dust collectors are fixedly installed on both sides of the top of the box, the first conveyor belt is fixedly installed at the bottom of the box, and the second conveyor belt is fixedly installed on the right side of the box.

[0005] The housing includes a first motor, a second motor, a first side seat, a crushing roller, a second side seat, a grinding roller, a screening plate, a vibrating motor, a feed port, and a discharge port. The first motor is fixedly installed on both sides of the top front of the housing, and the second motor is fixedly installed on both sides of the bottom front of the housing. The first side seat is fixedly installed on both sides of the top inside the housing. Two crushing rollers are movably installed between the two first side seats, with one end of each crushing roller rotatably connected to the inner wall of the housing and the other end fixedly connected to the output end of the first motor. The second side seat is fixedly installed on both sides of the middle inside the housing, with two grinding rollers movably installed between the two second side seats. One end of each grinding roller is rotatably connected to the inner wall of the housing and the other end fixedly connected to the output end of the second motor. A screening plate is fixedly installed at the bottom inside the housing, and a vibrating motor is fixedly installed on the left side of the bottom of the screening plate. A feed port is fixedly installed at the bottom of the housing, and a discharge port is fixedly installed at the bottom right side of the housing.

[0006] The hopper includes a shaft seat, a partition, and an elastic seat. Shaft seats are fixedly installed on both sides inside the hopper, and elastic seats are rotatably connected to both shaft seats.

[0007] The dust collector includes an inner seat, a filter plate, hanging ears, and an exhaust fan. The inner seat is fixedly installed on the inner wall of the dust collector, and the filter plate is movably installed on the top of the inner seat. Hanging ears are fixedly installed on both ends of the filter plate, and multiple exhaust fans are fixedly installed at the bottom of the dust collector.

[0008] Preferably, the two crushing rollers are meshed together.

[0009] Preferably, the two grinding rollers are meshed together.

[0010] Preferably, the screening plate is inclined to the right, the discharge port corresponds to the first conveyor belt, and the outlet corresponds to the second conveyor belt.

[0011] Preferably, the two partitions are arranged in a symmetrical structure.

[0012] Preferably, the two dust collection boxes are arranged symmetrically, and the filter plate is embedded in the interior of the dust collection box.

[0013] Preferably, the controller is electrically connected to the first motor, the second motor, the vibrating motor, the first conveyor belt, the second conveyor belt, and the exhaust fan.

[0014] Compared with the prior art, this utility model has the following advantages:

[0015] (1) The vibrating motor can drive the screen plate to vibrate and screen the fine material of the manufactured sand, so that the smaller particles of manufactured sand can pass through the screen plate and fall down, and then fall down from the discharge port to the first conveyor belt. The smaller particles of manufactured sand can be conveyed by the first conveyor belt; the larger particles of manufactured sand can flow to the right and flow out from the discharge port to the second conveyor belt, so the larger particles of manufactured sand can be conveyed by the second conveyor belt; thus, the raw materials after crushing can be automatically screened, and the workers do not need to use a separate screening device to screen the raw materials after crushing, which reduces the workload of the workers. The smaller and larger particles of manufactured sand can be separated and conveyed by the first and second conveyor belts, which can prevent the two from mixing together.

[0016] (2) Through the two partitions, when the raw material is poured into the hopper, the raw material can contact the partition. The partition is subjected to the downward gravity of the raw material, which causes the elastic seat to compress and deform, so that the two partitions can open and the raw material can enter the box for crushing. When all the material is discharged, the elastic seat can restore its deformation, so that the two partitions can be reset and closed, thereby preventing the dust generated during crushing from being emitted from the hopper. At the same time, the exhaust fan can draw the dust into the dust collection box, so that the dust can be adsorbed onto the filter plate, thereby further preventing the dust from being emitted everywhere and avoiding harm to the human body.

[0027] The housing 1 includes a first motor 101, a second motor 102, a first side seat 103, a crushing roller 104, a second side seat 105, a grinding roller 106, a screening plate 107, a vibrating motor 108, a discharge port 109, and a discharge port 110.

The first side seats 103 are fixedly installed on both sides of the top inside the housing 1. Two crushing rollers 104 are movably installed between the two first side seats 103, and one end of each crushing roller 104 is rotatably connected to the inner wall of the housing 1. The other end of the crushing roller 104 is fixedly connected to the output end of the first motor 101. The second side seat 105 is fixedly installed on both sides of the middle part of the box body 1. Two grinding rollers 106 are movably installed between the two second side seats 105. One end of the grinding roller 106 is rotatably connected to the inner wall of the box body 1, and the other end of the grinding roller 106 is fixedly connected to the output end of the second motor 102. A screening plate 107 is fixedly installed at the bottom of the box body 1. A vibration motor 108 is fixedly installed on the left side of the bottom of the screening plate 107. A discharge port 109 is fixedly installed at the bottom of the box body 1. A discharge port 110 is fixedly installed at the bottom right side of the box body 1.

[0028] The hopper 3 includes a bearing 301, a partition 302, and an elastic seat 303. The bearing 301 is fixedly installed on both sides inside the hopper 3, and the elastic seat 303 is rotatably connected to both bearings 301.

[0029] The dust collector 4 includes an inner seat 401, a filter plate 402, hanging ears 403, and an exhaust fan 404. The inner seat 401 is fixedly installed on the inner wall of the dust collector 4. The filter plate 402 is movably installed on the top of the inner seat 401. The hanging ears 403 are fixedly installed on both ends of the filter plate 402. Multiple exhaust fans 404 are fixedly installed at the bottom of the dust collector 4.

[0030] In this embodiment, the two crushing rollers 104 are meshed together.

[0031] In practical use, the first motor 101 can drive the two crushing rollers 104 to rotate relative to each other, so that the two crushing rollers 104 can crush the raw materials, thereby obtaining relatively homogeneous manufactured sand coarse material.

[0032] In this embodiment, the two grinding rollers 106 are meshed together.

[0033] In practical use, the second motor 102 can drive the two grinding rollers 106 to rotate in opposite directions, so that the two grinding rollers 106 can grind the coarse manufactured sand, thereby obtaining fine manufactured sand that meets the requirements of use.

[0034] In this embodiment, the screening plate 107 is inclined to the right, and the discharge port 109 corresponds to the first conveyor belt 5, and the discharge port 110 corresponds to the second conveyor belt 6.

[0035] In practical use, the vibrating motor 108 drives the screening plate 107 to vibrate and screen the fine manufactured sand, allowing smaller particles of manufactured sand to pass through the screening plate 107 and fall downwards, then fall downwards from the discharge port 109 onto the first conveyor belt 5, which conveys the smaller particles of manufactured sand. The larger particles of manufactured sand flow to the right and flow out from the discharge port 110 onto the second conveyor belt 6, which conveys the larger particles of manufactured sand. This allows for automatic screening of the crushed raw materials, eliminating the need for workers to use a separate screening device after crushing, thus reducing the workload of workers. Furthermore, the first conveyor belt 5 and the second conveyor belt 6 can separate and transport the smaller and larger particles of manufactured sand, preventing them from mixing together.

[0036] In this embodiment, the two partitions 302 are arranged in a symmetrical structure.

[0037] In practical use, after the raw material is poured into the hopper 3, it can come into contact with the partition 302. The partition 302 is subjected to the downward gravity of the raw material, which causes the elastic seat 303 to compress and deform, allowing the two partitions 302 to open and the raw material to enter the box 1 for crushing. After all the material is discharged, the elastic seat 303 can return to its original shape, allowing the two partitions 302 to reset and close, thereby preventing dust generated during crushing from being emitted from the hopper 3 and avoiding harm to the human body.

[0038] In this embodiment, the two dust collection boxes 4 are arranged in a symmetrical structure, and the filter plate 402 is embedded in the interior of the dust collection box 4.

[0039] In practical use, the exhaust fan 404 can draw dust into the dust collection box 4, so that the dust can be adsorbed onto the filter plate 402, thereby preventing the dust from spreading everywhere. The filter plate 402 is embedded in the dust collection box 4, making it easy to disassemble, clean and replace.

[0040] In this embodiment, the controller 2 is electrically connected to the first motor 101, the second motor 102, the vibration motor 108, the first conveyor belt 5, the second conveyor belt 6, and the exhaust fan 404.

[0041] In practical use, the controller 2 can control the working status of the first motor 101, the second motor 102, the vibrating motor 108, the first conveyor belt 5, the second conveyor belt 6, and the exhaust fan 404.

[0042] In addition, the structure, working principle, and corresponding supporting equipment of each exhaust fan, conveyor belt, motor, and related equipment all adopt existing technologies, which will not be described in detail here.

[0043] The working principle of the crushing and grinding equipment for producing circular manufactured sand mentioned in this utility model is as follows:

[0044] In use, when the raw material is poured into the hopper 3, it can come into contact with the partition 302. The partition 302 is subjected to the downward gravity of the raw material, which causes the elastic seat 303 to compress and deform, allowing the two partitions 302 to open and allowing the raw material to enter the box 1 for crushing. After all the material has been discharged, the elastic seat 303 can return to its original shape, allowing the two partitions 302 to reset and close, thereby preventing dust generated during crushing from escaping from the hopper 3 and avoiding harm to the human body.

[0045] Meanwhile, the exhaust fan 404 can draw dust into the dust collection box 4, so that the dust can be adsorbed onto the filter plate 402, thereby preventing the dust from spreading everywhere. The filter plate 402 is embedded in the dust collection box 4, making it easy to disassemble, clean and replace.

[0046] Then, the first motor 101 can drive the two crushing rollers 104 to rotate relative to each other, so that the two crushing rollers 104 can crush the raw material, thereby obtaining relatively homogeneous coarse manufactured sand, and the coarse manufactured sand can fall downward onto the grinding roller 106. Then, the second motor 102 can drive the two grinding rollers 106 to rotate relative to each other, so that the two grinding rollers 106 can grind the coarse manufactured sand, thereby obtaining fine manufactured sand that meets the requirements for use.

[0047] Then, the fine manufactured sand can fall downwards onto the screening plate 107. The vibrating motor 108 drives the screening plate 107 to vibrate and screen the fine manufactured sand, allowing smaller particles of manufactured sand to pass through the screening plate 107 and fall downwards through the discharge port 109 onto the first conveyor belt 5. The first conveyor belt 5 can transport the smaller particles of manufactured sand. The larger particles of manufactured sand can flow to the right and flow out from the discharge port 110 onto the second conveyor belt 6, which can transport the larger particles of manufactured sand. Thus, the crushed raw materials can be automatically screened, eliminating the need for workers to use a separate screening device after crushing, reducing the workload of workers. Furthermore, the first conveyor belt 5 and the second conveyor belt 6 can separate and transport the smaller and larger particles of manufactured sand, preventing them from mixing together.

[0048] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
