Description

Technical Field

[0001] The utility model relates to the field of construction, in particular to a device for quickly crushing building material waste. Background Art

[0002] Construction waste refers to the collective term for slag, waste concrete, waste bricks and stones, and other waste generated during demolition, construction, renovation, and repair activities in the construction industry. By source, construction waste can be divided into construction slag, renovation waste, demolition waste, and construction mud. By composition, construction waste can be divided into slag, concrete blocks, crushed stone, brick and tile fragments, waste mortar, mud, asphalt blocks, waste plastics, waste metal, and waste bamboo and wood.

[0003] When recycling construction waste, the waste needs to be crushed. After the commonly used construction waste crushing equipment crushes the construction waste, stones, mortar, steel bars, etc. are mixed together. The crushed slag needs to be transferred to other equipment for screening before the recyclable metals can be recycled. The process is time-consuming and labor-intensive. Utility Model Content

[0006] Furthermore, a first motor and a second motor are provided on the back of the shell, a feed hopper is provided on the top of the shell, a discharge port is provided on one side of the shell, a crushing box and a support plate are provided on the upper part of the shell, a discharge port is provided at the bottom of the crushing box, a roller is provided inside the crushing box, a crushing roller is connected to the outside of the roller, a gear is sleeved on the outside of the roller, and one end of the roller is connected to the output end of the first motor, and the output end of the second motor is connected to the first rotating shaft.

[0007] By adopting the above technical solution, construction waste enters the crushing box through the feed hopper, and the staff starts the first motor. Driven by the output end of the first motor, the gears engage, so that the roller drives the crushing roller to rotate and crush the construction waste into debris, which then falls onto the dividing plate through the discharge port.

[0008] Furthermore, the gears, rollers and crushing rollers are each provided with two groups, and the two groups of gears, rollers and crushing rollers are symmetrically distributed.

[0009] By adopting the above technical solution, driven by the output end of the first motor, the two rollers drive the crushing rollers to move in opposite directions through gear meshing, crushing the construction waste in the crushing box into debris, which is convenient for subsequent processing.

[0010] Furthermore, the sprockets, chains, collision blocks and eccentric wheels are each provided in two groups, and the two groups of sprockets, chains, collision blocks and eccentric wheels are symmetrically distributed.

[0011] By adopting the above technical solution, the eccentric wheel and the collision block collide with each other, causing the distribution plate to vibrate up and down, thereby accelerating the movement speed of the slag on the distribution plate. The chain is driven by the sprocket to move, and under the magnetic effect of the magnetic strip, metals such as iron that can be magnetically adsorbed are moved to the collection frame for recovery.

[0012] Furthermore, the dividing plate is in an inverted "J" shape.

[0013] By adopting the above technical solution, through chain sprocket transmission, when the magnetically absorbable debris moves to one side of the dividing plate, it is isolated and guided by the guide plate, increasing the distance between the debris and the magnetic strip, thereby achieving the purpose of weakening the magnetism.

[0014] Furthermore, there are a plurality of magnetic strips, and the plurality of magnetic strips are in contact with the bottom of the dividing plate.

[0015] By adopting the above technical solution, under the action of magnetism, the magnetic strips drive the magnetically adsorbed metal debris on the dividing plate, and the sprocket chain drives the metal to move to the collection frame to recover the metal.

By cooperating with the vibration spring, the distribution plate vibrates up and down to screen the debris. Metal debris containing iron and other metals that can be magnetically absorbed are attracted by the magnetic strip and driven by the sprocket and chain to move to the side of the collection frame. The debris that is not magnetically absorbed is quickly discharged through the discharge port.

[0018] Furthermore, a receiving groove is provided in the connecting plate, and the pull rod is slidably connected to the receiving groove.

[0021] By adopting the above technical solution, the metal-containing debris is collected by the collection frame. When a certain amount is collected, the collection frame is pulled out of the device from the chute by pulling the handle, and the debris in the frame is collected and put back into the device.

[0022] Furthermore, a water tank is provided in the middle of the top of the connecting plate, a water inlet is provided on the top of the water tank, a water pump is provided inside the water tank, the output end of the water pump is connected to a delivery pipe, one end of the delivery pipe is connected to a nozzle, and the outer surface of the nozzle is connected to an atomizing nozzle.

The output end of the second motor drives the first rotating shaft to rotate, and the first rotating shaft drives the eccentric wheel to rotate. By cooperating with the vibration spring, the distribution plate vibrates up and down to screen the slag. The metal slag containing iron and other magnetically attracted metals moves to the side of the collection frame under the adsorption of the magnetic strip. The slag that is not magnetically attracted quickly passes through the discharge port and is discharged, thereby accelerating the screening speed.

[0026] 2. The utility model is provided with a distribution chain, a sprocket and a magnetic strip. Under the action of magnetism, the magnetic strip drives the metal debris that can be magnetically absorbed on the distribution plate, and transmits the power through the chain sprocket. When the debris that can be magnetically absorbed moves to one side of the distribution plate, it is isolated and guided by the guide plate, thereby increasing the distance between the debris and the magnetic strip and weakening the magnetism, so that the debris falls into the collection frame for concentration, which is convenient for the subsequent metal recovery.

[0033] The following describes an embodiment of the present invention based on its overall structure.

Construction waste enters the crushing box 8 through the feed hopper 7, and the staff starts the first motor 2. Driven by the output end of the first motor 2, the gear 4 is engaged, so that the roller 3 drives the crushing roller 5 to rotate and crushes the construction waste into debris, which then falls onto the dividing plate 14 through the discharge port 32.

[0035] See Figure 1 and Figure 2 In the above embodiment, there are two groups of gears 4, rollers 3 and crushing rollers 5, and the two groups of gears 4, rollers 3 and crushing rollers 5 are symmetrically distributed. Driven by the output end of the first motor 2, the gears 4 are engaged, so that the two rollers 3 drive the crushing rollers 5 to move in opposite directions, crushing the construction waste in the crushing box 8 into slag, which is convenient for subsequent processing.

[0036] See Figure 2 and Figure 3 In the above embodiment, there are two groups of sprockets 17, chains 18, collision blocks 20 and eccentric wheels 19, and the two groups of sprockets 17, chains 18, collision blocks 20 and eccentric wheels 19 are symmetrically distributed. The eccentric wheels 19 and the collision blocks 20 collide with each other, causing the dividing plate 14 to vibrate up and down, thereby accelerating the movement speed of the slag on the dividing plate 14. The chain 18 is driven to move by the sprocket 17, and under the magnetic action of the magnetic strip 25, metals containing iron and other magnetically adsorbable metals are moved to the collection frame 11 for recovery.

[0037] See Figure 2In the above embodiment, the dividing plate 14 is in an inverted "J" shape and is driven by the chain 18 and sprocket 17. When the magnetically absorbable debris moves to one side of the dividing plate 14, it is isolated and guided by the guide plate 21, thereby increasing the distance between the debris and the magnetic strip 25, thereby achieving the purpose of weakening the magnetism.

[0038] See Figure 2 and Figure 3 In the above embodiment, a plurality of magnetic strips 25 are provided, and the plurality of magnetic strips 25 are in contact with the bottom of the dividing plate 14. Under the action of magnetism, the magnetic strips 25 drive the metal debris that can be magnetically adsorbed on the dividing plate 14 to move to the collection frame 11 through the sprocket 17 and the chain 18 to recover the metal.

[0039] See Figure 2 In the above embodiment, the collision block 20 abuts against the eccentric wheel 19. When the slag falls into the distribution plate 14, the staff starts the second motor 6. The output end of the second motor 6 drives the first rotating shaft 15 to rotate. The first rotating shaft 15 drives the eccentric wheel 19 to rotate. By cooperating with the vibration spring 13, the distribution plate 14 vibrates up and down to screen the slag. Metal slag containing iron and other metals that can be magnetically absorbed are attracted by the magnetic strip 25 and driven by the sprocket 17 and the chain 18 to move to the side of the collection frame 11. The slag that is not magnetically absorbed is quickly discharged from the device through the discharge port 10.

[0040] See Figure 4 In the above embodiment, a receiving groove is provided in the connecting plate 22, and the pull rod 24 is slidably connected to the receiving groove. When the magnetic strip 25 absorbs the column debris, the pull rod 24 is driven to slide in the receiving groove by the telescopic spring 23, so that the magnetic strip 25 vibrates up and down following the dividing plate 14, thereby preventing the distance between the debris and the magnetic strip 25 from increasing and losing magnetism. At the same time, when the magnetic strip 25 rotates to the bottom, it is limited by the pull rod 24 to prevent the magnetic strip 25 from detaching from the chain 18.

[0041] Referring to FIG. 2 , in the above embodiment, a chute is provided on the other side of the housing 1 , a handle 31 is provided on one side of the collection frame 11 , and the collection frame 11 is slidably connected to the chute. The collection frame 11 is used to collect metal-containing debris. When a certain amount of debris is collected, the collection frame 11 is pulled out of the chute by pulling the handle 31, and the debris in the frame is collected and placed back into the device.

[0042] Example 2: In order to avoid the harm to the workers caused by dust generated during crushing, Example 2 is improved on the basis of Example 1. Figure 2A water tank 26 is provided in the middle of the top of the connecting plate 22, and a water inlet 33 is provided on the top of the water tank 26. A water pump 27 is provided inside the water tank 26, and the output end of the water pump 27 is connected to a delivery pipe 28, and one end of the delivery pipe 28 is connected to a nozzle 29. The outer surface of the nozzle 29 is connected to an atomizing nozzle 30. Water is injected into the water tank 26 through the water inlet 33, and then driven by the output end of the water pump 27, the water is delivered to the nozzle 29 through the delivery pipe 28, and sprayed out through the atomizing nozzle 30 to spray the construction waste in the device, thereby suppressing the dust generated during crushing.

[0043] The implementation principle of the present utility model is as follows: construction waste is fed into the crushing box 8 through the feed bin, the staff starts the first motor 2, and under the drive of the output end of the first motor 2, the gear 4 is engaged, and the two rollers 3 respectively drive the crushing rollers 5 to rotate in opposite directions to grind the construction waste into slag, and the slag falls onto the distribution plate 14 through the discharge port 32. At this time, the second motor 6 is turned on, and the output end of the second motor 6 drives the first rotating shaft 15 to rotate. Under the drive of the first rotating shaft 15, the eccentric wheel 19 intermittently hits the collision block 20, and the vibration spring 13 cooperates to make the distribution plate 14 vibrate up and down, which will not be crushed. The adsorbed debris is quickly discharged from the device through the discharge port 10, and the debris that can be magnetically adsorbed is adsorbed on the dividing plate 14. At the same time, the sprocket 17 drives the chain 18 to move, and then drives the magnetic strip 25 to move. The iron-containing debris slowly moves to the side of the dividing plate 14 under the magnetic action of the magnetic strip 25. When it rotates to the guide plate 21, it is guided and isolated by the guide plate 21, so that the distance between the magnetic strip 25 and the debris increases and loses its magnetism. The debris falls into the collection frame 11 for concentration. When a certain amount is collected, the collection frame 11 is pulled out of the device by the handle 31 to recycle the metal debris inside.
