Description

Technical Field

[0001] This utility model relates to the field of sand making technology, and in particular to a sand making device with a discharge grading structure. Background Technology

[0002] Sand making equipment is specifically designed for producing construction sand and road sand. It can address some shortcomings in the material processing process, such as:

[0003] Conventional sand making equipment cannot screen and classify the output material, resulting in all the material flowing out at once. This leads to the presence of many large particles in the material, resulting in poor product quality. Furthermore, dust is released into the environment during the operation of the sand making equipment, which is detrimental to its normal operation. Utility Model Content

[0004] The purpose of this invention is to provide a sand making device with a discharge grading structure to solve the problems mentioned in the background art.

[0005] A sand making device with a discharge grading structure includes a box body, a first fixed plate, and extrusion rollers: the upper end of the box body is provided with a first fixed plate, the upper end of the first fixed plate is provided with a feed hopper, the upper end of the feed hopper is provided with a dust removal mechanism, the outer side of the dust removal mechanism is provided with a protective mechanism, the extrusion rollers are symmetrically arranged inside the box body, the lower end of the box body is provided with a discharge port, and a screening mechanism is provided between the discharge port and the extrusion rollers, the screening mechanism being located inside the box body.

[0006] When the device is in use, materials are fed into the box through the feed hopper, then the materials are squeezed by the extrusion rollers, then the sand is graded by the screening mechanism, and finally the sand is discharged through the discharge port; the box and the first fixed plate are fixed by bolts, so the equipment can be opened by disassembling the two.

[0007] Preferably, the dust removal mechanism includes a water inlet pipe and an atomizing hole, the water inlet pipe is disposed inside the feed hopper, and the lower end of the water inlet pipe is provided with an atomizing hole.

[0008] The water inlet pipe is connected to an external water source, and water can be atomized and discharged through the atomizing holes, thereby achieving the purpose of dust removal.

[0009] Preferably, the protective mechanism includes a fixing ring and baffles. The fixing ring is rotatably disposed on the outer side of the water inlet pipe. The fixing ring does not overlap with the position of the atomizing hole. Baffles are disposed on both sides of the fixing ring.

[0010] When material is placed on the baffle, the material will cause the baffle and the fixed ring to rotate under the action of gravity, causing the material to flow into the inside of the feed hopper. Afterwards, the baffle and the fixed ring will return to their original positions under their own gravity.

[0011] Preferably, inclined guide plates are provided on both sides of the inside of the box, and the guide plates are located between the feed hopper and the extrusion roller.

[0012] After the material flows into the inside of the box through the feed hopper, the material will come into contact with the extrusion rollers through the guide plate, and the extrusion rollers will crush the material into sand.

[0013] Preferably, the screening mechanism includes a screen, a circulation port, and a vibration mechanism. The circulation port is located on one side of the inside of the housing, and the vibration mechanism is located on the other side of the inside of the housing. One end of the screen is rotatably disposed inside the circulation port, and the other end of the screen is connected to the screen.

[0014] When the device is in use, the screen will screen and filter the sand. The screen will move downward under the action of the material's gravity. The vibration mechanism drives the screen to vibrate, preventing material from remaining on the screen surface. Because the screen is inclined, the material will flow downward through the screen and flow out to the outside through the circulation port. The screen is "L" shaped, which can prevent material from flowing out through the gaps.

[0015] Preferably, the vibration mechanism includes a second fixed plate, a fixed column, a connecting column, and a fixed spring. The second fixed plate is disposed on the side of the housing. The fixed column is rotatably disposed at the lower end of the second fixed plate. The connecting column is slidably disposed inside the fixed column. The connecting column passes through the fixed column and is rotatably connected to the screen. The fixed spring is disposed on the outside of the connecting column and is located inside the fixed column.

[0016] When the screen is subjected to the weight of the material, it will cause the connecting column to move downwards, and at the same time, it will compress the fixing spring. Then, the fixing spring will drive the connecting column and the screen to return to their original positions, thereby causing the screen to vibrate. This prevents the material from not moving downwards on the surface of the screen. When the screen vibrates, the second fixing plate and the fixing column will rotate, and the connecting column and the screen will also rotate, thus ensuring the stability of the connecting column when it moves.

[0017] Preferably, a lifting column is connected to the side of the circulation port, the upper side of the lifting column is connected to the feed hopper, a motor is provided at the upper end of the lifting column, and an auger is connected to the output end of the motor. The auger is rotatably arranged inside the lifting column.

[0018] Larger materials enter the lifting column through the circulation port, and then the motor drives the auger to rotate, thereby lifting the material into the feed hopper, where it is then crushed and sanded again.

[0019] The beneficial effects of this utility model are:

[0020] 1. When the device is in use, it will classify and screen the materials through the screen, so that the larger materials will flow back to the top through the auger for re-sanding, while the smaller materials will flow down through the screen. The screen will vibrate under the action of gravity of the materials, thereby preventing the materials from staying on the surface of the screen.

[0021] 2. When materials are fed into the hopper, the materials will move the baffle. Then the baffle will return to its original position under its own gravity. The baffle prevents dust from overflowing, and water is sprayed through the atomizing holes to reduce the dust content in the air. Attached Figure Description

[0028] 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.

[0029] In practical implementation: such as Figure 1-4 As shown, a sand making device with a discharge grading structure includes a box body 1, a first fixed plate 2, and extrusion rollers 9. The upper end of the box body 1 is provided with the first fixed plate 2, the upper end of the first fixed plate 2 is provided with a feed hopper 3, the upper end of the feed hopper 3 is provided with a dust removal mechanism, the outer side of the dust removal mechanism is provided with a protective mechanism, the extrusion rollers 9 are symmetrically arranged inside the box body 1, the lower end of the box body 1 is provided with a discharge port, and a screening mechanism is provided between the discharge port and the extrusion rollers 9. The screening mechanism is located inside the box body 1.

[0030] When the device is in use, materials are fed into the housing 1 through the feed hopper 3, and then the materials are extruded by the extrusion roller 9. The sand is then graded by the screening mechanism and discharged through the discharge port. The housing 1 and the first fixed plate 2 are fixed by bolts, so the device can be opened by disassembling the two.

[0031] The dust removal mechanism includes a water inlet pipe 4 and an atomizing hole 5. The water inlet pipe 4 is located inside the feed hopper 3, and the lower end of the water inlet pipe 4 is provided with an atomizing hole 5.

[0032] The water inlet pipe 4 is connected to an external water source, and water can be atomized and discharged through the atomizing hole 5, thereby achieving the purpose of dust removal.

[0033] The protective mechanism includes a fixing ring 6 and a baffle 7. The fixing ring 6 is rotatably installed on the outside of the water inlet pipe 4. The fixing ring 6 does not overlap with the position of the atomizing hole 5. Baffles 7 are installed on both sides of the fixing ring 6.

[0034] When material is placed on baffle 7, the material will cause baffle 7 and fixed ring 6 to rotate under the action of gravity, causing the material to flow into the interior of feed hopper 3. Afterwards, baffle 7 and fixed ring 6 will return to their original positions under their own gravity.

[0035] Inclined guide plates 8 are provided on both sides of the inside of the box 1, and the guide plates 8 are located between the feed hopper 3 and the extrusion roller 9.

[0036] When the material flows into the interior of the box 1 through the feed hopper 3, the material will come into contact with the extrusion roller 9 through the guide plate 8, and the extrusion roller 9 will crush the material into sand.

[0037] The screening mechanism includes a screen 14, a circulation port 15, and a vibration mechanism. The circulation port 15 is located on one side of the inside of the box 1, and the vibration mechanism is located on the other side of the inside of the box 1. One end of the screen 14 is rotated and located inside the circulation port 15, and the other end of the screen 14 is connected to the screen 14.

[0038] When the device is in use, the screen 14 will screen and filter the sand. The screen 14 will move downward under the action of the material's gravity. The vibration mechanism drives the screen 14 to vibrate, which prevents the material from remaining on the surface of the screen 14. Since the screen 14 is inclined, the material will flow downward through the screen 14 and flow out to the outside through the circulation port 15. The screen 14 is "L" shaped, which can prevent the material from flowing out from the gap.

[0039] The vibration mechanism includes a second fixed plate 10, a fixed column 11, a connecting column 12, and a fixed spring 13. The second fixed plate 10 is disposed on the side of the housing 1. The fixed column 11 is rotatably disposed at the lower end of the second fixed plate 10. The connecting column 12 is slidably disposed inside the fixed column 11. The connecting column 12 passes through the fixed column 11 and is rotatably connected to the screen 14. The fixed spring 13 is disposed on the outside of the connecting column 12 and is located inside the fixed column 11.

[0040] When the screen 14 is subjected to the weight of the material, it will cause the connecting column 12 to move downward, and at the same time, it will compress the fixing spring 13. Then, the fixing spring 13 will cause the connecting column 12 and the screen 14 to return to their original positions, thereby causing the screen 14 to vibrate, preventing the material from not moving downward on the surface of the screen 14. When the screen 14 vibrates, the second fixing plate 10 and the fixing column 11 will rotate, and the connecting column 12 and the screen 14 will also rotate, thereby ensuring the stability of the connecting column 12 when it moves.

[0041] A lifting column 16 is connected to the side of the circulation port 15. The upper side of the lifting column 16 is connected to the feed hopper 3. A motor 17 is installed at the upper end of the lifting column 16. The output end of the motor 17 is connected to an auger 18. The auger 18 is rotatably installed inside the lifting column 16.

[0042] Larger materials enter the interior of the lifting column 16 through the circulation port 15. Then, the motor 17 drives the auger 18 to rotate, thereby lifting the material into the interior of the feed hopper 3, where it is then crushed and pressed into sand.
