Description

Technical Field

[0001] This utility model relates to the field of construction waste cleaning technology, specifically a construction waste cleaning device. Background Technology

[0002] Construction waste refers to the garbage generated during the construction process. With the rapid pace of urban modernization, numerous construction sites inevitably emerge in cities. The construction or demolition of buildings generates a large amount of construction waste, including waste concrete blocks and asphalt concrete blocks. These waste bricks must be cleaned up by waste disposal equipment to prevent pollution.

[0003] Existing construction waste cleaning equipment has poor filtration effect when filtering crushed waste because the filter screen is stationary. Over time, the filter screen may even become clogged. At the same time, the waste that is not completely crushed needs to be manually picked and collected again for secondary crushing, which increases the workload and reduces work efficiency.

[0004] The patent document with publication number CN217450323U discloses a construction waste cleaning device for civil engineering. The device consists of a drive wheel, a driven wheel, a filter screen, a rotating block, ball bearings, a guide plate, a receiving box, and a recycling box, all housed within a cleaning box. While the waste is being crushed, the rotating block strikes the filter screen, accelerating the filtration process. The crushed waste passes through the filter screen and is then guided to the recycling box for recovery. Incompletely crushed waste passes through the filter screen and is directly guided to the receiving box for centralized collection and secondary crushing. This eliminates the need for manual sorting and improves the efficiency of waste cleaning.

[0005] However, when the construction waste cleaning device for civil engineering is crushing, the crushed construction waste falls directly onto the top of the filter screen, which may cause the construction waste to accumulate on the top of the filter screen, resulting in serious damage to the filter screen and large-scale blockage of the filter screen, thus reducing the screening efficiency. Therefore, it is necessary to propose a construction waste cleaning device with better crushing and screening effect. Utility Model Content

[0006] The purpose of this utility model is to provide a construction waste cleaning device to solve the construction waste disposal problem mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a construction waste cleaning device, comprising a screening box and a crushing box disposed on the top of the screening box, wherein a screening mechanism is disposed inside the screening box and a crushing mechanism is disposed inside the crushing box;

[0008] The screening mechanism includes a fixed plate, a motor, a distribution plate, a screening plate, a trough, rollers, a fixed seat, a connecting rod, a rotating shaft, a crank, and a rotating shaft. The fixed plate is located on the right side of the screening box, the motor is located on the right side of the fixed plate, the distribution plate is fixedly connected to the upper left side of the fixed plate, the screening plate is fixedly connected to the lower left side of the fixed plate, the trough is opened through one side of the screening box, the rollers are located at the bottom of the inner wall of the trough, the fixed seat is fixedly connected to the right side of the fixed plate, the connecting rod is rotatably connected to one side of the fixed seat, the rotating shaft is rotatably connected to one side of the connecting rod, the crank is rotatably connected to one side of the connecting rod, and the rotating shaft is fixedly connected to one side of the crank.

[0009] Preferably, the crushing mechanism includes a gear cover, a first crushing roller, a second crushing roller, a first gear, a second gear, and a second motor. The gear cover is located on the right side of the crushing chamber. The first crushing roller and the second crushing roller are rotatably connected inside the crushing chamber. The first gear and the second gear are rotatably connected to the right side of the crushing chamber. The second motor is located on the right side of the first gear.

[0010] Preferably, a connector is fixedly connected to the top of the screening box, a discharge port one is provided on one side of the screening box, a discharge port two is provided at the bottom of the screening box, an inlet is fixedly connected to the top of the crushing box, and a foot is provided at the bottom of the discharge port two, with four feet evenly distributed.

[0011] Preferably, gear one and gear two mesh, but gear one and gear two do not contact the right side of the crushing box. During operation, gear one drives crushing roller one to rotate clockwise, and gear two drives crushing roller two to rotate counterclockwise.

[0012] Preferably, the crushing box has two through holes on the right side, and each of the crushing roller one and crushing roller two has a rotating shaft at its center. The two rotating shafts pass through the two through holes and are fixedly connected to gear one and gear two, respectively. The output end of motor two is connected to gear one, and when motor two rotates, it drives gear one to rotate.

[0013] Preferably, the equalizing plate and the screening plate are set in an inclined state. The inclined state can improve the efficiency of screening. The through holes on the surface of the equalizing plate are larger than the screening holes of the screening plate. The equalizing plate does not actually perform screening. It mainly spreads the crushed construction waste evenly on the surface of the screening plate, thus avoiding the direct input of piled construction waste onto the surface of the screening plate, which would cause the screening plate to break.

[0016] 1. This construction waste cleaning device, through its screening mechanism, ensures that after construction waste passes through the crushing box, it is first evenly spread by a distribution plate, and then falls onto the top of the screening plate for screening. This avoids the crushed construction waste from directly accumulating behind the screening plate, which could cause damage or blockage. Furthermore, rollers are installed on the inner wall of the channel to reduce friction during reciprocating motion and improve screening efficiency.

[0017] 2. The construction waste cleaning device, through the set crushing mechanism, allows construction waste to enter the crushing box after being fed into the inlet. When motor 2 is started, gear 1 and gear 2 drive crushing roller 1 and crushing roller 2 to rotate clockwise and counterclockwise respectively.

[0024] Please see Figures 1-4 This utility model provides a technical solution:

[0025] Example 1:

[0026] A construction waste cleaning device includes a screening box 1 and a crushing box 2 disposed on the top of the screening box 1, and a screening mechanism is provided inside the screening box 1.

[0027] The screening mechanism includes a fixed plate 101, a motor 102, a distribution plate 103, a screening plate 104, a through groove 105, a roller 106, a fixed seat 107, a connecting rod 108, a rotating shaft 109, a crank 110, and a rotating shaft 111. The fixed plate 101 is located on the right side of the screening box 1, and the motor 102 is located on the right side of the fixed plate 101. The rotating shaft 111 connected to the output end of the motor 102 will drive the crank 110 to rotate, which in turn drives the connecting rod 108, which is rotatably connected to one side of the crank 110, to move. Finally, the fixed seat 107 moves accordingly. At this time, the fixed seat 107 drives the fixed plate 101 to perform linear reciprocating motion, and the distribution plate 103 and the screening plate 104, which are fixedly connected to one side of the fixed plate 101, will also perform linear reciprocating motion. The equalizing plate 103 is fixedly connected to the upper left side of the fixed plate 101, and the screening plate 104 is fixedly connected to the lower left side of the fixed plate 101. The equalizing plate 103 and the screening plate 104 are set in an inclined state, which can improve the efficiency of screening. The through holes on the surface of the equalizing plate 103 are larger than the screening holes of the screening plate 104. The equalizing plate 103 does not actually perform screening; its main function is to spread the crushed construction waste evenly on the surface of the screening plate 104, thus preventing piles of construction waste from being directly thrown onto the surface of the screening plate 104 and causing damage to the screening plate 104. The through groove 105 is opened through one side of the screening box 1. Roller 106 is located at the bottom of the inner wall of the through groove 105. Roller 106 contacts the bottom of the screening plate 104 to reduce friction during movement. Fixed seat 107 is fixedly connected to the right side of fixed plate 101. Connecting rod 108 is rotatably connected to one side of fixed seat 107. Rotating shaft 109 is rotatably connected to one side of connecting rod 108. Crank 110 is rotatably connected to one side of connecting rod 108. Rotating shaft 2 111 is fixedly connected to one side of crank 110. The output end of motor 102 is connected to one end of rotating shaft 2 111. When motor 102 starts, it drives rotating shaft 2 111 and crank 110 to rotate. After passing through the crushing box 2, the crushed construction waste enters the screening box 1 through the connecting piece 3. It then passes through the equalizing plate 103 and the screening plate 104 in sequence. The reciprocating fixed plate 101 drives the equalizing plate 103 and the screening plate 104 to move. The construction waste falling on the surface of the equalizing plate 103 will be spread evenly on the surface of the equalizing plate 103 and fall evenly into the surface of the screening plate 104 through the through holes opened on the surface of the equalizing plate 103. Finally, the finely crushed construction waste is screened through the through holes opened on the surface of the screening plate 104.

[0028] Example 2:

[0029] Based on Embodiment 1, a crushing mechanism is provided inside the crushing box 2. The crushing mechanism includes a gear cover 201, a first crushing roller 202, a second crushing roller 203, a first gear 204, a second gear 205, and a second motor 206. The gear cover 201 is located on the right side of the crushing box 2. The first crushing roller 202 and the second crushing roller 203 are rotatably connected inside the crushing box 2. The first gear 204 and the second gear 205 are rotatably connected to the right side of the crushing box 2. The first gear 204 and the second gear 205 mesh, but the first gear 204 and the second gear 205 do not engage with the crushing box 2. On the right side, during operation, gear 1 204 drives crushing roller 1 202 to rotate clockwise, and gear 2 205 drives crushing roller 2 203 to rotate counterclockwise. Two through holes are provided on the right side of the crushing box 2. A rotating shaft is located at the center of both crushing roller 1 202 and crushing roller 2 203. The two rotating shafts pass through the two through holes and are fixedly connected to gear 1 204 and gear 2 205, respectively. The output end of motor 2 206 is connected to gear 1 204. When motor 2 206 rotates, it drives gear 1 204 to rotate. Motor 2 206 is located to the right of gear 1 204. After starting motor 2 206, gears 1 204 and 2 205 drive crushing roller 1 202 and crushing roller 2 203 to rotate clockwise and counterclockwise, respectively, thus crushing the construction waste located between crushing roller 1 202 and crushing roller 2 203.

[0030] The top of the screening box 1 is fixedly connected to the connector 3. The screening box 1 has a discharge port 4 on one side. The side of the discharge port 4 is set as an inclined surface to facilitate discharge. The bottom of the screening box 1 has a discharge port 5. The top of the crushing box 2 is fixedly connected to the inlet 6. The bottom of the discharge port 5 is equipped with a foot bracket 7. There are four foot brackets 7 evenly distributed.

[0031] Working principle:

[0032] First, through the crushing mechanism, the construction waste is fed into the crushing box 2 after being fed into the inlet 6. The motor 206 is started, and at this time, the gear 1 204 and the gear 2 205 drive the crushing roller 1 202 and the crushing roller 2 203 to rotate clockwise and counterclockwise respectively. At this time, the construction waste between the crushing roller 1 202 and the crushing roller 2 203 is crushed so as to facilitate further processing of the construction waste.

[0033] Furthermore, through the screening mechanism, after the construction waste passes through the crushing box 2, the crushed construction waste will enter the screening box 1 through the connecting part 3. First, it will pass through the equalizing plate 103, and then through the screening plate 104. The reciprocating fixed plate 101 drives the equalizing plate 103 and the screening plate 104 to move. The construction waste falling on the surface of the equalizing plate 103 will be spread evenly on the surface of the equalizing plate 103 under the reciprocating action. Then, it will fall evenly into the surface of the screening plate 104 through the through holes opened on the surface of the equalizing plate 103. Finally, the fine construction waste will be screened through the through holes opened on the surface of the screening plate 104. The crushed construction waste passes through the equalizing plate 103 first and then through the screening plate 104. That is, it is spread evenly first and then screened, which improves the screening efficiency and avoids the screen plate 104 from being directly piled up and damaged or blocked.

[0034] Furthermore, under the action of motor 102, the rotating shaft 111 connected to the output end of motor 102 will drive crank 110 to rotate, thereby driving the connecting rod 108 rotatably connected to one side of crank 110 to move. Finally, the fixed seat 107 moves accordingly. At this time, the fixed seat 107 drives the fixed plate 101 to perform linear reciprocating motion, and the equalizing plate 103 and screening plate 104 fixedly connected to one side of the fixed plate 101 will also perform linear reciprocating motion, thereby achieving the effect of reciprocating screening.

[0035] Furthermore, a through groove 105 is provided on one side of the screening box 1, and a roller 106 is provided at the bottom of the inner wall of the through groove 105. The roller 106 contacts the bottom of the screening plate 104 to reduce friction during movement.

[0036] Furthermore, a discharge port 4 is provided on one side of the screening box 1, and the side of the discharge port 4 is set as an inclined surface to facilitate material discharge.
