Abstract
Description
Technical Field
[0001] This utility model relates to the field of crushing equipment technology, and in particular to a crushing device for construction waste. Background Technology
[0002] Construction waste refers to various solid wastes generated during the construction and renovation of buildings. It generally includes magnetic metal waste such as steel bars, wires, nails, screws, and nuts, and has high recycling value.
[0003] In the prior art, Chinese utility model patent CN212284230U discloses a construction waste crushing and recycling device for construction projects. During operation, waste is poured in through the inlet. As the waste passes through the first crushing roller group, the first crushing roller rotates in the opposite direction to the first and second auxiliary crushing rollers on the left and right sides. This, combined with the first auxiliary crushing teeth, crushes the waste. Spraying nozzles one and three spray water during operation to prevent dust from being stirred up. After being crushed by the first crushing roller group, the waste... After passing through the sorting baffle, the waste material is sorted. Smaller pieces fall directly onto the screw conveyor and are conveyed out, while larger pieces enter the second crushing roller group. The second crushing roller group works on the same principle as the first crushing roller group, causing the waste material to be crushed a second time. After being crushed, the waste material passes through the magnetic suction plate, where iron objects are separated out. The remaining waste material falls into the screw conveyor wheel. The motor drives the bearing rod, causing the screw conveyor wheel to rotate and convey the waste material out, thus completing the crushing process.
[0004] During operation, the device uses magnetic plates to magnetically attract iron objects mixed in with construction waste, thereby separating the iron objects from the construction waste. However, the iron objects separated by the magnetic plates cannot be actively discharged and need to be manually cleaned by the user, which results in poor ease of use. Utility Model Content

[0062] Preferred, such as Figure 1 , 2 As shown in Figure 5, in this embodiment, the third conveying device 49 includes: a conveying housing 491, a pair of drive shafts 492, a driving device (not shown in the figure), a third conveyor belt 493, and several conveying plates 494; the conveying housing 491 is fixedly mounted on the frame body, the bottom of the inner cavity of the conveying device is connected to the second discharge port, and the top of the inner cavity of the conveying housing 491 is connected to the discharge channel 4911; a pair of drive shafts 492 are disposed in the inner cavity of the conveying housing 491, the pair of drive shafts 492 are arranged in parallel, and both ends of any one drive shaft 492 are rotatably connected to the inner wall of the conveying housing 491; the driving device is fixedly mounted on the conveying housing 491, and the driving end of the driving device is connected to one of the drive shafts 494. 92 are connected to drive one of the drive shafts 492 to rotate; the third conveyor belt 493 is sleeved on the pair of drive shafts 492, and the third conveyor belt 493 is linearly displaced along its circumference under the drive of one of the drive shafts 492; several conveyor plates 494 are fixedly arranged on the outer circumferential surface of the third conveyor belt 493, and the several conveyor plates 494 are spaced apart along the circumference of the third conveyor belt 493.

During the linear displacement of the third conveyor belt 493 along its circumference, the several conveyor plates 494 are driven by the third conveyor belt 493 to convey the construction waste located at the bottom of the inner cavity of the conveyor housing 491 to the discharge channel 4911.
[0063] Furthermore, such as Figures 1-3As shown, the device also includes: a fourth conveying device 8; the fourth conveying device 8 is disposed at the bottom of the inner cavity of the main body 2, the fourth conveying device 8 is connected to the tail end of the partition 3, and the output end of the fourth conveying device 8 is connected to the third discharge port 22 of the main body 2 for conveying construction waste. In this embodiment, the fourth conveying device 8 is preferably a belt conveyor.
[0064] When the equipment is running, the user feeds construction waste into the crusher 1 through the input end of the crusher 1. The crusher 1 crushes the waste and outputs it through the output end to the upper side of the partition plate 3, where it is stored in the storage cavity 23 of the main body 2. At the same time, the motor 42 drives the main shaft 41 to rotate synchronously with several metal plates 411 and several actuating plates 4111 mounted on the main shaft 41. During this process, construction waste of the appropriate size stored in the storage cavity 23 passes through the metal plate on the lower side of the main shaft 41. The waste passes through the gap between the metal plates 411 and slides down along the guide plate 3 onto the fourth conveying device 8, where it is discharged to the outside of the main body 2 via the third discharge port 22. During the process of the construction waste passing through the gap between the metal plates 411, the second permanent magnet 4121 magnetically attracts the metal waste mixed in with the construction waste onto itself and the metal plates 411. As the main shaft 41 rotates further, the second permanent magnet 4121 and the metal plates 411 drive the metal waste magnetically attracted to their surfaces, as well as the non-metallic materials carried by the metal waste. Construction waste made of magnetic metal is moved clockwise along the circumference of the main shaft 41 until it is driven to the position of the first baffle 43. There, the metal waste and non-magnetic metal construction waste are scraped off by the first baffle 43 and slide along the guide of the first baffle 43 toward the discharge gap 432. During this sliding process along the guide of the first baffle 43, the metal waste is attracted to the bottom surface of the conveyor belt of the belt conveyor device 6 under the magnetic force of the first permanent magnet 7, and is moved toward the output end of the belt conveyor device 6 by the drive of the conveyor belt. The metal waste is then moved to the position of the belt conveyor... After the output end of the conveying device 6 is positioned, the metal waste is weakened by the magnetic constraint of the first permanent magnet 7, and the metal waste falls onto the top surface of the first conveyor belt on the first conveying device 5 under the action of gravity. Driven by the first conveyor belt, the metal waste is output to the outside of the main body 2 of the machine casing through the first discharge port 21. The non-magnetic metal construction waste scraped off by the first baffle 43 finally falls onto the fourth conveying device 8 through the discharge gap 432, and is discharged to the outside of the main body 2 of the machine casing through the third discharge port 22 by the fourth conveying device 8.
[0065] In this embodiment, multiple actuating plates 4111 disposed around the metal plate 411 continuously actuate the excessively large construction waste mixed in the storage cavity 23 as the main shaft 41 rotates, causing it to move away from the main shaft 41, thereby promoting the sinking of smaller construction waste. During this process, the stop bar 45, driven by the linear module 462, periodically moves axially back and forth through the guide hole 461, thereby controlling the timed opening of the feeding window. When the stop bar 45 moves towards the third conveying device 49 under the drive of the linear module 462, it flips... After the rotating plate 44 loses the support of the stop bar 45, the bottom end of the rotating plate 44 reverses towards the third conveyor 49 under the action of gravity, causing the unloading window to open. The construction waste accumulated in the storage cavity 23 falls through the unloading window onto the second conveyor 47, and the second conveyor 47 conveys the construction waste to the bottom of the inner cavity of the conveyor housing 491 through the second discharge port. As the third conveyor 49 operates, the third conveyor 49 drives the third conveyor belt 493 and the multiple conveyor plates 494 arranged on the third conveyor belt 493 along the third conveyor belt 493. The circumferential linear motion conveys the construction waste accumulated at the bottom of the inner cavity of the conveying housing 491 to the discharge channel 4911. The construction waste then flows back into the crusher 1 along the discharge channel 4911 for further crushing. As the construction waste slides down the discharge channel 4911, larger volumes of magnetic metal waste mixed in with it are retained in the discharge channel 4911 under the magnetic attraction of the third permanent magnet 4912. This allows the user to retrieve the metal waste from the discharge channel 4911 when the device is not in operation. Alternatively, the user can use tools to obtain the metal waste in the discharge channel 4911 while the device is in operation. In this embodiment, the discharge channel is a groove-shaped part made of magnetic metal. The tools used by the user to obtain the metal waste in the discharge channel 4911 while the device is in operation include, but are not limited to, garbage tongs, fire tongs, etc. Secondly, after the stop bar 45 is displaced and reset under the drive of the linear module 462, the stop bar 45 pushes the flip plate 44 to close the discharge window again, so that the construction waste falling from the output end of the crusher 1 is stored in the storage cavity 23 again.
[0066] Above, refer to Figures 1-5 A construction waste crushing device according to an embodiment of the present invention is described, which has the following beneficial effects:

This device, by setting a belt conveyor 6 and a first permanent magnet 7 inside the main body 2 of the casing, uses the magnetic force of the first permanent magnet 7 to magnetically attract the metal waste picked up by the sorting module to the belt conveyor 6, and the belt conveyor 6 to transport the metal waste to the first conveying device 5, and finally the first conveying device 5 to transport the metal waste to the outside of the main body 2 of the casing, enhances the ease of use of this device and solves the problems existing in the prior art.
[0068] 2. This device uses multiple actuating plates 4111 set on the circumferential outer edge of the metal plate 411. During the rotation of the metal plate 411, the actuating plates 4111 continuously actuate the excessively large construction waste, causing it to move away from the main shaft 41. This promotes the sinking of smaller construction waste in the storage cavity and prevents excessively large construction waste from being retained at the bottom of the storage cavity, thereby improving the working efficiency of the device.
[0069] 3. This device uses a push plate 4111 with an arc-shaped side 41111 and a second baffle 48 with a second assembly notch 481 to push over large construction waste. This can effectively prevent large construction waste from flipping over the main shaft 41 under the action of the push plate 4111, thus avoiding adverse effects on the waste picking and separation effect of this device.
[0070] 4. This device is equipped with a feeding window, drive assembly 46, baffle 45, tilting plate 44, second conveyor 47, and third conveyor 49. However, excessively large construction waste is conveyed back to the crusher 1 by the second conveyor 47 and the third conveyor 49 for secondary crushing, thereby improving the crushing effect of construction waste in this device.
