[0017] Beneficial effects of the present invention:

[0018] 1. The present invention can collect larger construction waste that does not meet the crushing requirements and transport it between two crushing rollers for re-crushing through the arrangement of multiple crushing units, thereby effectively ensuring that the construction waste particles falling through the sieve holes on the sieve plate meet the standards. The crushed construction waste falls onto the magnetic suction unit, and the metal impurities in the construction waste are adsorbed by the magnetic suction unit. At this moment, the separation and collection of metal impurities in the construction waste are completed. Compared with the existing device, the present invention can peel off the metal impurities in the construction waste when crushing it, and at the same time, crush the larger particles that do not meet the crushing requirements.

[0019] 2. The present invention allows the fallen construction waste particles to fall into a cleaning box, and the water pre-injected into the cleaning box is used to soak and clean them. During the soaking and cleaning, the sand and gravel after the construction waste is crushed can be cleaned. At this time, the dust in the construction waste is integrated with the water, and can fall through the water curtain through the setting of the dust reduction unit. Therefore, a large amount of dust generated when the crushing roller crushes the construction waste is adsorbed and resisted, thereby effectively achieving dust reduction, and the water curtain that adsorbs the dust falls into the cleaning box, so that the dust is precipitated in the cleaning box. At the same time, the dust reduction unit can circulate the water in the cleaning box for dust reduction, soaking to fuse the dust and water, and finally achieving the separation of sand and gravel and dust while completing the cleaning of the crushed construction waste.

[0020] 3. The present invention enables multiple shovels to move at one time by opening the conveyor belt. When the shovel moves, the substandard construction waste that falls into the receiving bucket is scooped up and transported, and then transported to between two crushing rollers for re-crushing. The setting of multiple crushing units can effectively avoid the occurrence of incomplete crushing when the construction waste is crushed. At the same time, when the shovel scoops up the construction waste in the receiving bucket, when the shovel moves out of the receiving bucket, the rotating plate can be flipped and reset.

[0021] 4. The present invention manually pushes the push rod to move the scraper to the side away from the spring, and then the electric slider opens to make the bottom of the scraper contact with the surface of the magnetic plate, and then loosens the push rod. Under the action of the spring, the push rod drives the scraper to scrape the metal particles adsorbed on the magnetic plate into the outer edge box, and finally completes the falling collection through the discharge port.

[0022] 5. The present invention drives the rotating wheel to rotate by rotating the rotating shaft. When the rotating wheel rotates, the piston rod is driven by the push plate to perform compression movement in the air cylinder, and then the water on one side of the cleaning box is transported to the annular water tank through the delivery pipe. Then the annular water tank supplies water to the water curtain box. The water in the water curtain box falls into the working box to form a surrounding water curtain. The dust generated when the construction waste is crushed can be adsorbed and resisted through the formation of the water curtain. Finally, the water curtain falls into the cleaning box to realize circulating water supply. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] The invention discloses a device for crushing, decomposing and reusing solid construction waste, which decomposes solid waste in construction waste and recycles it as a resource. Specifically, the metal in concrete blocks is recovered by crushing, and sand and dust are separated during soaking and washing of the crushed construction waste so as to recycle the sand and gravel.

[0036] like Figure 1-Figure 8As shown in the figure, it includes an operation box 1. On the upper part of the inner cavity of the operation box 1, connecting plates 20 are symmetrically installed. Between the two connecting plates 20, support rods 201 are fixedly installed. A lower plate 203 is installed on the two support rods 201 together. A crushing roller 202 is rotatably installed between the two support rods 201 through an electric slider. A cleaning plate 204 is installed on the lower plate 203 through multiple groups of springs. Below the crushing roller 202, U-shaped frames 21 connected to the inner cavity side wall of the operation box 1 are symmetrically installed. Inside the U-shaped frames 21, rectangular blocks 22 are fixedly installed. A central rod 221 is fixedly installed between the two rectangular blocks 22. Sieve plates 215 rotatably connected to the central rod 221 are arranged on both sides of the central rod 221. Multiple crushing units 2 are symmetrically arranged between the two U-shaped frames 21. The multiple crushing units 2 can re-convey the construction waste that has not fallen through the sieve plates 215 to between the two crushing rollers 202 for multiple crushing. Below the multiple crushing units 2, a magnetic attraction unit 3 connected to the operation box 1 is provided. At the lower part of the operation box 1, a cleaning box 4 is fixedly installed. In the middle of the cleaning box 4, a slope panel 41 is fixedly installed. A dust reduction unit is installed between the operation box 1 and the cleaning box 4.

[0037] After starting the electric slider to drive the two crushing rollers 202 to rotate towards each other, the construction waste is put into the middle of the operation box 1. Subsequently, after being crushed by the crushing rollers 202, the construction waste evenly falls onto the two sieve plates 215. The construction waste that meets the crushing requirements falls on the sieve plates 215. Since the sieve plates 215 are inclined, when the construction waste falls onto the sieve plates 215, it falls in an inclined manner. Thus, it can ensure that the construction waste that meets the crushing requirements fully falls when spreading evenly, avoiding the situation that when the crushed construction waste falls, the construction waste that meets the crushing requirements is mixed and cannot fully fall due to accumulation. Through the setting of the multiple crushing units 2, the larger construction waste that does not meet the crushing requirements can be collected and conveyed between the two crushing rollers 202 for re-crushing, thereby effectively ensuring that the construction waste particles falling through the sieve holes on the sieve plates 215 meet the standards;

[0038] The crushed construction waste falls onto the magnetic attraction unit 3. The magnetic attraction unit 3 adsorbs the metal impurities in the construction waste. At this moment, the separation and collection of the metal impurities in the construction waste are completed. The fallen construction waste particles fall into the cleaning box 4 and are soaked and cleaned by the water pre-injected into the cleaning box 4. When soaking and cleaning, the sand and gravel after the construction waste is crushed can be cleaned. At this time, the dust in the construction waste is fused with the water. Through the setting of the dust reduction unit, it can fall through the water curtain, so as to adsorb and resist a large amount of dust and the like generated when the crushing rollers 202 crush the construction waste, thereby effectively achieving dust reduction. And the water curtain adsorbing dust falls into the cleaning box 4, making the dust precipitate in the cleaning box 4. At the same time, the dust reduction unit can recycle the water in the cleaning box 4 for dust reduction;

[0039] Compared with the existing device, the present invention can strip metal impurities from construction waste during crushing, and at the same time re-crush larger particles that do not meet the crushing requirements. By soaking, the dust is fused with water, and finally, while the crushed construction waste is being cleaned, the sand and dust can be separated.

[0040] In the middle of the U-shaped frame 21, a driving wheel 211 is slidably installed through an electric slider. Both the upper and lower parts of the driving wheel 211 are engaged with racks 212 that are slidably connected to the U-shaped frame 21. On both sides of the driving wheel 211, through grooves are provided on the U-shaped frame 21. A moving box 213 is slidably installed in the through grooves. The two moving boxes 213 on both sides are respectively connected to the racks 212 on both sides. A T-shaped groove is provided in the middle of the moving box 213. A connecting block 214 is slidably installed in the groove. One side of the connecting block 214 is fixedly connected to a sieve plate 215. A U-shaped discharge plate 216 is jointly installed on both sides of the sieve plate 215.

[0041] When the electric slider is started to drive the driving wheel 211 to rotate, when the driving wheel 211 rotates, it drives the two racks 212 to move closer to or away from each other. When the two racks 212 move, they respectively drive the moving boxes 213 on both sides to adjust the distance, thereby facilitating the adjustment of the inclination angles of the two sieve plates 215 on both sides. By adjusting the inclination angles of the two sieve plates 215, the screening speed of the crushed construction waste can be controlled. The larger construction waste that does not pass through the sieve plate 215 finally slides into the receiving hopper 231 through the gap between the sieve plate 215 and the discharge plate 216, thus facilitating the next round of crushing.

[0042] An electric push rod 222 is fixedly installed on the upper end surface of the rectangular block 22. A guide plate 223 is jointly fixedly installed between the electric push rods 222 on the two rectangular blocks 22. The top of the guide plate 223 is placed directly below the two crushing rollers 202. A notch is provided in the slope surface of the guide plate 223 and communicates with the middle. On both sides of the lower end surface of the U-shaped frame 21, hanging plates are symmetrically installed. A hydraulic rod 23 is fixedly installed on one side of the hanging plate. A receiving hopper 231 is jointly installed between the two corresponding hydraulic rods 23.

[0043] Through the setting of the receiving hopper 231, the construction waste that does not meet the crushing standard can be collected for re-crushing.

[0044] A support frame 24 fixedly connected to the inner cavity of the operation box 1 is provided above the receiving hopper 231. A conveyor belt 241 is provided in the middle of the support frame 24. A plurality of shovel plates 242 are equally spaced and installed on the upper part of the conveyor belt 241. A rotating plate 232 is rotatably installed on one side of the receiving hopper 231. Below the rotating plate 232, a plurality of L-shaped blocks fixedly connected to the receiving hopper 231 are provided. Springs fixedly connected to the rotating plate 232 are provided on the L-shaped blocks.

[0045] By opening the conveyor belt 241, multiple shovel plates 242 are moved at one time. When the shovel plates 242 move, they scoop up the substandard construction waste that falls into the receiving bucket 231 and transport it, and then transport it to between the two crushing rollers 202 for further crushing. The setting of multiple crushing units can effectively avoid incomplete crushing of the construction waste. At the same time, when the shovel plates 242 scoop up the construction waste in the receiving bucket 231, when the shovel plates 242 move out of the receiving bucket 231, the rotating plate 232 can be flipped over and reset.

[0046] The magnetic unit 3 includes a rotating rod 31, which is rotatably connected to the work box 1 through an electric slider. A clamping plate 32 is circumferentially installed on the outer wall of the rotating rod 31. A front side frame 33 is provided on the side of the clamping plate 32 away from the rotating rod 31. The front side frame 33 and the clamping plate 32 are connected by a spring. A magnetic plate 34 is commonly installed between the front side frame 33 and the clamping plate 32. Side grooves 35 are opened on both sides of the front side frame 33. L-shaped stoppers 36 for resisting the magnetic plate 34 are connected in the side grooves 35 by springs.

[0047] The magnetic plate 34 can be provided to absorb metal impurities in the crushed construction waste, thereby completing the separation of metal particles in the construction waste. At the same time, as the rotating rod 31 rotates, the multiple magnetic plates 34 are driven to rotate in opposite positions. On the one hand, the received construction waste can be spread out, and on the other hand, the crushed construction waste can be dumped into the cleaning box 4 for soaking and cleaning to remove dust from the sand and gravel.

[0048] An outer edge box 37 is rotatably installed on one side of the working box 1. A pushing rod 371 is provided on the outer edge box 37 and slides inside the outer edge box 37. A spring is provided on the outer sleeve of the pushing rod 371. A scraping piece 372 is slidably installed on one end of the pushing rod 371 through an electric slider. A discharge port 373 is opened at the lower part of the outer edge box 37.

[0049] The push rod 371 is manually pushed to move the scraper 372 to the side away from the spring, and then the electric slider is opened to make the bottom of the scraper 372 contact the surface of the magnetic plate 34, and then the push rod 371 is loosened. Under the action of the spring, the push rod 371 drives the scraper 372 to scrape the metal particles adsorbed on the magnetic plate 34 into the outer edge box 37, and finally complete the falling and collection through the discharge port 373.

[0050] The dust reduction unit includes an annular water tank 51 supported on the upper part of the inner cavity of the working box 1, and a water curtain box 52 is installed at the lower part of the annular water tank 51. A plurality of delivery pipes 53 are installed at equal intervals on one side of the annular water tank 51, and a one-way valve is provided at the lower part of the delivery pipe 53. Through the setting of the one-way valve, when the piston rod 59 is compressed, the delivery pipe 53 can only transport the water in the cleaning box 4 to the annular water tank 51, and the lower end of the delivery pipe 53 is placed in the cleaning box 4, and the lower parts of the plurality of delivery pipes 53 are connected together with a conduction pipe 54.

[0051] An air cylinder 58 is fixedly installed on one side of the cleaning box 4, and the end of the conduction tube 54 away from the delivery tube 53 is connected to the air cylinder 58. A piston rod 59 is slidably installed in the air cylinder 58. A rotating shaft 55 rotatably connected to the working box 1 is provided directly below the rotating rod 31. A rotating wheel 56 is fixedly installed on the end of the rotating shaft 55 away from the working box 1. A pushing plate 57 is rotatably installed on one side of the rotating wheel 56, and one side of the pushing plate 57 is located in the piston rod 59 and slides.

[0052] The rotation of the rotating shaft 55 drives the rotating wheel 56 to rotate. When the rotating wheel 56 rotates, the piston rod 59 is driven by the push plate 57 to perform compression movement in the air cylinder 58, and then the water on one side of the cleaning box 4 is transported to the annular water tank 51 through the delivery pipe 53. Then the annular water tank 51 supplies water to the water curtain box 52. The water in the water curtain box 52 falls into the working box 1 to form a surrounding water curtain. The formation of the water curtain can absorb and resist the dust generated when the construction waste is crushed. Finally, the water curtain falls into the cleaning box 4 to realize circulating water supply.

[0053] The slope plate 41 separates the cleaning box 4 into two spaces, and the higher side of the slope plate 41 is close to the conveying pipe 53 .

[0054] Both the rotating shaft 55 and the rotating rod 31 are provided with pulleys, and a belt is commonly connected between the pulleys.

[0055] When the present invention is in use, construction waste is put into the middle of the working box 1, and then the construction waste is crushed by the crushing roller 202 and falls evenly onto the two sieve plates 215. The construction waste that meets the crushing requirements falls on the sieve plates 215. Since the sieve plates 215 are inclined, the construction waste falls on the sieve plates 215 in an inclined manner, thereby ensuring that the construction waste that meets the crushing requirements falls fully when it is evenly spread, and avoiding the construction waste that meets the crushing requirements from being mixed and unable to be fully crushed due to accumulation when the crushed construction waste falls. When the driving wheel 211 rotates, it drives the two racks 212 to approach or turn to each other. When the two racks 212 move, they drive the moving boxes 213 on both sides to adjust the spacing, so as to facilitate the regulation of the inclination angles of the two sieve plates 215 on both sides. By adjusting the inclination angles of the two sieve plates 215, the sieving speed of the crushed construction waste can be controlled. The larger construction waste that has not been sieved by the sieve plate 215 will eventually slide between the sieve plate 215 and the discharge plate 216 into the receiving bucket 231, so as to facilitate the next round of crushing.

[0056] The conveyor belt 241 is opened to allow the multiple shovel plates 242 to be displaced and moved at one time. When the shovel plates 242 move, the substandard construction waste that falls into the receiving bucket 231 is scooped up and transported, and then transported to between the two crushing rollers 202 for re-crushing. The setting of multiple crushing units can effectively avoid the situation that the construction waste is not completely crushed when being crushed. At the same time, when the shovel plates 242 scoop up the construction waste in the receiving bucket 231, when the shovel plates 242 move out of the receiving bucket 231, the rotating plate 232 can be reversed and reset. The setting of the magnetic suction plate 34 can absorb the metal impurities in the crushed construction waste to complete the separation of the metal particles in the construction waste. At the same time, as the rotating rod 31 rotates, the multiple magnetic suction plates 34 are driven to rotate in different positions. On the one hand, the received construction waste can be spread out, and on the other hand, the crushed construction waste can be dumped into the cleaning box 4 for soaking and cleaning to remove dust in the sand and gravel.

[0057] The push rod 371 is manually pushed to move the scraper 372 to the side away from the spring, and then the electric slider is opened to make the bottom of the scraper 372 contact the surface of the magnetic plate 34, and then the push rod 371 is loosened. Under the action of the spring, the push rod 371 drives the scraper 372 to scrape the metal particles adsorbed on the magnetic plate 34 into the outer edge box 37, and finally completes the falling collection through the discharge port 373. The rotation of the rotating shaft 55 drives the rotating wheel 56 to rotate. When the rotating wheel 56 rotates, it drives the piston rod 59 to perform compression movement in the air cylinder 58 through the push plate 57, and then the water on one side of the cleaning box 4 is transported to the annular water tank 51 through the delivery pipe 53. Then the annular water tank 51 supplies water to the water curtain box 52, and the water in the water curtain box 52 falls into the working box 1 to form a surrounding water curtain. The formation of the water curtain can adsorb and resist the dust generated when the construction waste is crushed, and finally the water curtain falls into the cleaning box 4 to realize circulating water supply.

[0058] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements all fall within the scope of the present invention to be protected.
