Description

Technical Field

[0001] This utility model relates to the field of sand making machine technology, and in particular to a vertical sand making machine with a grading screen and vibrating feeding mechanism. Background Technology

[0002] A sand making machine is a mechanical device used to process raw materials such as stone and ore into sand particles. Sand making machines are widely used in industries such as construction, transportation, and mining, mainly for producing construction sand and concrete aggregates. With the rapid development of the construction industry, the demand for sand and gravel aggregates is increasing daily. Traditional sand making equipment faces many challenges in terms of production efficiency, finished sand quality, and energy consumption. Therefore, a vertical sand making machine with a grading and vibrating feeding mechanism is needed.

[0003] Traditional sand making machines can usually only crush sand and gravel into particles of a single size. When production needs change and materials need to be crushed into different sizes, operators have to change to different types of sand making machines. This process not only increases the purchase and maintenance costs of equipment and reduces the practicality and flexibility of the equipment, but also traditional vertical crushing machines usually do not have effective dust suppression devices during the crushing process, resulting in a large amount of dust being released into the air during operation. This not only causes serious air pollution, but also poses a threat to the health of workers. Long-term exposure to high dust environments may lead to respiratory diseases, occupational diseases and other health problems. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a vertical sand making machine with a grading screen and vibrating feeding mechanism.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A vertical sand making machine with a grading and screening feeding mechanism includes a housing. A feed hopper is fixed to the top of the housing. Horizontal grooves are symmetrically formed on both outer walls of the feed hopper. A second rotating shaft is slidably connected to the inner walls of the two horizontal grooves. A reset mechanism for resetting the second rotating shaft is provided on one outer wall of the feed hopper. A crushing mechanism is provided on the inner wall of the feed hopper. Vertical grooves are symmetrically formed on both outer walls of the housing. A third rotating shaft is provided on the inner walls of the two vertical grooves. A sprocket is sleeved on one outer wall of both the second and third rotating shafts. A chain is provided on one outer wall of the housing, with both ends of the chain meshing with the two sprockets. A rotating mechanism for rotating the third rotating shaft is provided on the other outer wall of the housing. A moving mechanism for moving the third rotating shaft is provided on the other outer wall of the housing. The inner wall of the chamber is inclined with two U-shaped plates, and a first filter screen is fixed to the inner wall of each U-shaped plate. The mesh diameter of the first filter screen gradually decreases. A vibration mechanism is provided at the bottom of each U-shaped plate to vibrate the two U-shaped plates respectively. A through hole is opened at the bottom of the chamber, and a second filter screen is fixed in the through hole. A water tank is fixed at the bottom of the chamber and is connected to the through hole. A filtration mechanism is provided inside the water tank. A dust suppression mechanism is provided inside the chamber. During use, this device can crush sand and gravel materials of different particle sizes according to actual needs without changing equipment, which improves the practicality and flexibility of the device. Through the design of the dust suppression mechanism, dust can be treated in the crushing process, reducing the release of dust in the air, reducing environmental pollution, and protecting the health of workers.

[0007] Preferably, the moving mechanism includes a second support plate fixed to the outer wall of one end of the housing. A hydraulic push rod is fixed to the top of the second support plate, and a first ring is fixed to the output end of the hydraulic push rod, which is sleeved on one end of the third rotating shaft. The resetting mechanism includes a connecting plate fixed to the outer wall of one end of the housing. A slide rod is provided through the side wall of the connecting plate, and a second ring is fixed to one end of the slide rod, which is sleeved on one end of the second rotating shaft. A second spring is sleeved on the side wall of the slide rod, and both ends of the second spring are fixed to the connecting plate and the second spring, respectively. Driving the hydraulic push rod drives the third rotating shaft along the two vertical grooves. The device moves up and down, and in conjunction with the chain and two sprockets, drives the second rotating shaft to move left and right along the two transverse grooves. This causes the second crushing roller to gradually move away from or closer to the first crushing roller, thus adjusting the distance between the two crushing rollers. This allows for the crushing of sand and gravel materials of different particle sizes according to actual needs without the need to change equipment, improving the practicality and flexibility of the device. When the size of the second and first crushing rollers increases or decreases, the second spring is in a stretched or compressed state. When it is not necessary to change the distance between the second and first crushing rollers, the hydraulic push rod drives the third rotating shaft to rise or fall, which, in conjunction with the second spring, allows the second crushing roller to reset.

[0008] Preferably, the crushing mechanism includes a first rotating shaft rotatably connected to the inner wall of the feed hopper. A first crushing roller is sleeved on the side wall of the first rotating shaft. A first motor is fixed to the other end of the outer wall of the feed hopper, and the output shaft of the first motor is fixed to the first rotating shaft. A second crushing roller is sleeved on the side wall of the second rotating shaft. The rotating mechanism includes a circular seat. A circular seat is provided on the outer wall of the other end of the housing near one of the vertical grooves. The other end of the third rotating shaft is rotatably connected to the circular seat. A second motor is fixed to the outer wall of the circular seat, and the output shaft of the second motor is fixed to the third rotating shaft. The first motor is driven to rotate in conjunction with the first rotating shaft to drive the first crushing roller to rotate. At the same time, the second motor is driven to rotate the third rotating shaft. The chain and two sprockets drive the second rotating shaft to rotate, thereby driving the second crushing roller to rotate. At this time, the first crushing roller and the second crushing roller rotate in a counter-rotating manner, which can perform the crushing of sand and gravel materials.

[0009] Preferably, the vibration mechanism includes four first support plates, which are respectively fixed at the four corners of the inner side wall of the housing. A guide rod is provided through the top of each of the four first support plates, and one end of each guide rod is fixed to the bottom of a U-shaped plate. A first spring is sleeved on the side wall of each of the four guide rods, and one end of each first spring is fixed to the U-shaped plate. The other end of each first spring is fixed to one of the four first support plates. A third motor is fixed to the outer side wall of the housing. The output shaft of the third motor is sleeved with a cam, and the cam is adapted to the U-shaped plate. The third motor drives two cams to rotate rapidly. When the cam contacts the bottom of the U-shaped plate, the U-shaped plate moves upward, and the four guide rods move upward along the top of the four first support plates. At this time, the four first springs are compressed. When the cam and the U-shaped plate are no longer in contact, the reaction force of the four compressed first springs causes the U-shaped plate to move downward. This rapid, repeated operation causes the first filter to vibrate, preventing the first filter from becoming clogged.

[0010] Preferably, the dust suppression mechanism includes two connecting pipes, which are symmetrically fixed to the top of the inner side wall of the tank. Multiple atomizing nozzles are linearly fixed at equal intervals on the side walls of the two connecting pipes. A water pump is fixed to the bottom of the water tank, and a T-junction is fixed to the outlet of the water pump, with both ends of the T-junction connected to the two connecting pipes respectively. The filtration mechanism includes multiple filter layers, all fixed to the inner side wall of the water tank and located above the water pump. During the crushing process, the water pump draws clean water from the tank into the two connecting pipes through the T-junction and sprays it evenly onto the surface of the sand and gravel material through the multiple atomizing nozzles to suppress dust, preventing the release of large amounts of dust generated during crushing into the air, thus preventing air pollution and protecting the health of workers. The wastewater after dust suppression is filtered through multiple filter layers and then re-enters the water tank for recycling, avoiding water waste.

[0011] Preferably, the outer wall of the box is provided with a first discharge port and a second discharge port, and the lower edges of the first discharge port and the second discharge port are flush with the lowest ends of the two U-shaped plates. A first guide plate and a second guide plate are fixed on the outer wall of the box near the first discharge port and the second discharge port, respectively, and the bottom of the first guide plate and the second guide plate are inclined. A third discharge port is provided on the outer wall of the box near the bottom. During crushing, the crushed sand and gravel material first falls onto the upper surface of the first filter screen with a larger mesh diameter. At this time, the particle size that meets the actual requirements falls onto the upper surface of the first filter screen with a smaller mesh diameter. It is further screened and refined by the first filter screen with a smaller mesh diameter. A part of it falls into the second guide plate through the second discharge port for collection, and the other part of the smaller particles falls onto the surface of the second filter screen and is collected through the third discharge port. The particles that do not meet the actual requirements enter the first guide plate through the first discharge port and are collected for secondary crushing.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. During use, the second rotating shaft is moved by the moving mechanism, which can adjust the distance between the first crushing roller and the second crushing roller. It can crush sand and gravel materials of different particle sizes according to actual needs without changing equipment, thus improving the practicality and flexibility of the device.

[0014] 2. Through the design of the dust suppression mechanism, dust can be suppressed in the crushing process of sand and gravel materials, reducing the release of dust in the air, reducing environmental pollution, and protecting the health of workers.

[0015] 3. A graded screening and feeding mechanism is achieved through two spiral plates and two first filters. The vibration mechanism prevents the first filters from clogging, ensuring that particles are effectively screened according to size, thereby improving the accuracy and efficiency of screening.

[0016] 4. Wastewater generated during the crushing process can be filtered through a filtration system and then recycled back into the water tank, effectively avoiding water waste. Attached Figure Description

The moving mechanism of unit 2 has two inclined U-shaped plates 14 on the inner side wall of the housing 1. A first filter screen 17 is fixed on the inner side wall of each U-shaped plate 14, and the mesh diameter of the first filter screen 17 gradually decreases. A vibration mechanism for vibrating the two U-shaped plates 14 is provided at the bottom of each U-shaped plate 14. A through hole is opened at the bottom of the housing 1, and a second filter screen 9 is fixed in the through hole. A water tank 3 is fixed at the bottom of the housing 1, and the water tank 3 is connected to the through hole. A filtration mechanism is provided inside the water tank 3. A dust suppression mechanism is provided inside the housing 1. During use, this device can crush sand and gravel materials of different particle sizes according to actual needs without changing equipment, which improves the practicality and flexibility of the device. Through the design of the dust suppression mechanism, dust can be treated on the sand and gravel materials during the crushing process, reducing the release of dust in the air, reducing environmental pollution, and protecting the health of workers.

[0027] In this utility model, the moving mechanism includes a second support plate 30, which is fixed to the outer wall of one end of the housing 1. A hydraulic push rod 21 is fixed to the top of the second support plate 30, and a first ring is fixed to the output end of the hydraulic push rod 21. The first ring is sleeved on one end of the third rotating shaft 22. The resetting mechanism includes a connecting plate 25, which is fixed to the outer wall of one end of the housing 1. A slide rod 26 is provided through the side wall of the connecting plate 25. A second ring is fixed to one end of the slide rod 26, and the second ring is sleeved on one end of the second rotating shaft 29. A second spring 27 is sleeved on the side wall of the slide rod 26, and the two ends of the second spring 27 are fixed to the connecting plate 25 and the second spring 27, respectively. Driving the hydraulic push rod 21 drives the third rotating shaft 22 to move up and down along the two vertical grooves 19. The second crushing roller 12 moves left and right along the two transverse grooves 18, driven by the chain 24 and two sprockets 23. This causes the second crushing roller 12 to move away from or closer to the first crushing roller 11, thus adjusting the distance between them. This allows for the crushing of sand and gravel materials of different particle sizes according to actual needs without the need to change equipment, improving the practicality and flexibility of the device. When the distance between the second crushing roller 12 and the first crushing roller 11 increases or decreases, the second spring 27 is in a stretched or compressed state. When it is not necessary to change the distance between the second crushing roller 12 and the first crushing roller 11, the hydraulic push rod 21 drives the third rotating shaft 22 to rise or fall. With the help of the second spring 27, the second crushing roller 12 can be reset.

[0028] In this invention, the crushing mechanism includes a first rotating shaft 28, which is rotatably connected to the inner wall of the feed hopper 2. A first crushing roller 11 is sleeved on the side wall of the first rotating shaft 28. A first motor 13 is fixed to the other end of the outer wall of the feed hopper 2, and the output shaft of the first motor 13 is fixed to the first rotating shaft 28. A second crushing roller 12 is sleeved on the side wall of a second rotating shaft 29. The rotating mechanism includes a circular seat 38. A circular seat 38 is provided on the outer wall of the other end of the housing 1 near one of the vertical grooves 19. The other end of the third rotating shaft 22 is connected to the circular seat 38. The circular seat 38 is rotatably connected, and a second motor 37 is fixed on the outer wall of the circular seat 38. The output shaft of the second motor 37 is fixed to the third rotating shaft 22. The first motor 13 drives the first crushing roller 11 to rotate in conjunction with the first rotating shaft 28. At the same time, the second motor 37 drives the third rotating shaft 22 to rotate. The chain 24 and two sprockets 23 drive the second rotating shaft 29 to rotate, which in turn drives the second crushing roller 12 to rotate. At this time, the first crushing roller 11 and the second crushing roller 12 rotate in a counter-rotating manner, which can carry out the crushing of sand and gravel materials.

[0029] In this invention, the vibration mechanism includes four first support plates 31, which are respectively fixed at the four corners of the inner side wall of the housing 1. A guide rod 32 is provided through the top of each of the four first support plates 31, and one end of each guide rod 32 is fixed to the bottom of a U-shaped plate 14. A first spring 33 is sleeved on the side wall of each of the four guide rods 32, and one end of each first spring 33 is fixed to the U-shaped plate 14. The other ends of each first spring 33 are fixed to the four first support plates 31. A third motor 10 is fixed to the outer side wall of the housing 1. The output shaft of the third motor 10 is sleeved with a cam 34, and the cam... The wheel 34 and the guide plate 14 are adapted to drive two third motors 10 to drive two cams 34 to rotate rapidly. When the bottom of the cam 34 and the guide plate 14 are in contact, the guide plate 14 moves upward and the four guide rods 32 move upward along the top of the four first support plates 31. At this time, the four first springs 33 are in a compressed state. When the cam 34 and the guide plate 14 are no longer in contact, the guide plate 14 moves downward under the reaction of the four compressed first springs 33. By repeating this operation quickly, the first filter screen 17 can be made to vibrate, thus preventing the first filter screen 17 from becoming clogged.

[0030] In this invention, the dust suppression mechanism includes two connecting pipes 16, which are symmetrically fixed to the top of the inner wall of the housing 1. Multiple atomizing nozzles 36 are linearly fixed at equal intervals on the sidewalls of the two connecting pipes 16. A water pump 35 is fixed to the bottom of the water tank 3, and a three-way pipe 20 is fixed to the outlet of the water pump 35. Both ends of the three-way pipe 20 are connected to the two connecting pipes 16 respectively. The filtration mechanism includes multiple filter layers 15, all of which are fixed to the inner wall of the water tank 3 and located near the water pump 3. Above 5, during the crushing process, the driving water pump 35 draws clean water from the water tank 3 into the two connecting pipes 16 through the three-way pipe 20, and sprays it evenly onto the surface of the sand and gravel material through multiple atomizing nozzles 36 to suppress dust, prevent the release of a large amount of dust generated during crushing into the air, prevent air pollution, and prevent the impact on the health of workers. The wastewater after dust suppression is filtered through multiple filter layers 15 and then re-enters the water tank 3 for recycling, avoiding waste of water resources.

[0031] In this invention, the outer wall of the box body 1 is provided with a first discharge port 4 and a second discharge port 6, and the lower edges of the first discharge port 4 and the second discharge port 6 are flush with the lowest ends of the two U-shaped plates 14, respectively. A first guide plate 5 and a second guide plate 7 are fixed to the outer wall of the box body 1 near the first discharge port 4 and the second discharge port 6, respectively, and the bottom of the first guide plate 5 and the second guide plate 7 are both inclined. A third discharge port 8 is provided near the bottom of the outer wall of the box body 1. During crushing, the crushed sand and gravel material first falls into the first discharge port with a larger mesh diameter. On the upper surface of filter screen 17, particles that meet the actual size requirements fall onto the upper surface of the first filter screen 17 with a smaller mesh diameter. They are then further sieved and refined by the first filter screen 17 with a smaller mesh diameter. A portion of the particles fall into the second guide plate 7 through the second discharge port 6 for collection, while the smaller particles fall onto the surface of the second filter screen 9 and are collected through the third discharge port 8. Particles that do not meet the actual size requirements enter the first guide plate 5 through the first discharge port 4 and are collected for secondary crushing.

[0032] Working Principle: During operation, a large amount of clean water is first injected into the water tank 3. The distance between the first crushing roller 11 and the second crushing roller 12 is adjusted according to the required sand particle size. During adjustment, the hydraulic push rod 21 drives the third rotating shaft 22 to move up and down along the two vertical grooves 19. This, in conjunction with the chain 24 and two sprockets 23, drives the second rotating shaft 29 to move left and right along the two horizontal grooves 18. This causes the second crushing roller 12 to gradually move away from or closer to the first crushing roller 11, thus adjusting the distance between them. This allows for the crushing of sand and gravel materials of different particle sizes according to actual needs without requiring equipment replacement, improving the practicality and flexibility of the device. When using, first connect the first motor 13... The power switch activates the first motor 13, which, in conjunction with the first rotating shaft 28, drives the first crushing roller 11 to rotate. Simultaneously, the power switch of the second motor 37 is activated, driving the second motor 37 to rotate the third rotating shaft 22. This, in conjunction with the chain 24 and two sprockets 23, drives the second rotating shaft 29 to rotate, which in turn drives the second crushing roller 12 to rotate. At this point, the first crushing roller 11 and the second crushing roller 12 rotate in a counter-rotating manner, enabling the crushing of sand and gravel. The crushed sand and gravel first falls onto the upper surface of the first filter screen 17, which has a larger mesh diameter. Then, the power switches of the two third motors 10 are activated, driving them to drive the two cams 34 to rotate rapidly. When the cams 34 contact the bottom of the guide plate 14, the guide plate 14 moves upward. At this time, the four guide rods 32 move upward along the top of the four first support plates 31 respectively. At this time, the four first springs 33 are all in a compressed state. When the cam 34 and the guide plate 14 are no longer in contact, the four compressed first springs 33 cause the guide plate 14 to move downward. This rapid repeated operation can make the first filter screen 17 vibrate, avoiding clogging of the first filter screen 17. At this time, the particles that meet the actual requirements fall into the upper surface of the first filter screen 17 with a smaller mesh diameter. They are further screened and refined by the first filter screen 17 with a smaller mesh diameter. A part of them fall into the second guide plate 7 through the second discharge port 6 for collection, while the other part, which is even smaller, falls into the surface of the second filter screen 9 and is further processed by the second guide plate 7. The material can be collected at the three discharge ports 8. If the particle size does not meet the actual requirements, it will be collected in the first guide plate 5 through the first discharge port 4 and prepared for secondary crushing. During the crushing process, the power switch of the water pump 35 is turned on, and the water pump 35 drives the clean water in the water tank 3 to be drawn into the two connecting pipes 16 through the three-way pipe 20. The water is then evenly sprayed on the surface of the sand and gravel material through multiple atomizing nozzles 36 to reduce dust and prevent a large amount of dust generated during crushing from being released into the air, thus preventing air pollution and protecting the health of workers. The wastewater after dust reduction is filtered through multiple filter layers 15 and then re-enters the water tank 3 for recycling, thus avoiding waste of water resources.
