[0027] This specific embodiment is a rapid screening crusher for construction waste.

[0028] The above-mentioned utility model cannot ensure that construction waste of different sizes is crushed. Small construction waste is likely to fall into the inside between the blades during the rotation of the crushing knives in the crushing mechanism and cannot be crushed a second time, reducing the completeness of crushing. Moreover, there is a lot of dust in the construction waste, including non-solid waste such as silt, which is not convenient to handle.

[0029] Its structural schematic diagram is as Figures 1-4As shown in the figure. A rapid screening and crushing machine for construction waste includes a chassis 4 installed on the ground. The top of the chassis 4 is supported and installed with a screening box body 2 through vibration box plates 41 and vibration springs 42. The vibration box plates 41 are symmetrically arranged up and down, and the vibration springs 42 are fixedly installed between the vibration box plates 41. At one end of the chassis 4, two groups of protective side plates 43 are fixedly installed at the top, and between the other end of the chassis 4 and the vibration box plate 41, they are fixedly installed through a frame plate 44. The vibration box plates 41 and the vibration springs 42 cooperate to carry the screening box body 2 and achieve the effect of vibration screening, and the screening box body 2 and the chassis 4 are set as an inclined box body. Construction waste generally refers to muck, waste concrete, waste bricks and stones, and other wastes generated by people in the production activities of the construction industry such as demolition, construction, decoration, and repair. It has a certain weight, and after being crushed, due to the inclination of the screening box body 2, it will roll down according to its own weight, and cooperate with the vibration springs 42 to make the screening box body 2 vibrate, so as to achieve the effect of vibration screening.

[0030] Inside the screening box body 2, an A sieve plate layer 22, a B sieve plate layer 23, a C sieve plate layer 24, and a D sieve plate layer 25 are respectively fixedly installed. A limiting plate 21 is fixedly installed at the bottom end of the screening box body 2, and the aperture sizes of the A sieve plate layer 22, the B sieve plate layer 23, the C sieve plate layer 24, and the D sieve plate layer 25 are arranged in sequence. During the process of construction waste rolling down according to its own weight, the settings of the A sieve plate layer 22, the B sieve plate layer 23, the C sieve plate layer 24, and the D sieve plate layer 25 enable the construction waste to be screened through sieve meshes with different apertures. At the bottom position of the screening box body 2, multiple groups of storage boxes 3 are correspondingly placed. A filter plate is placed and installed inside the storage box 3. It is convenient for the construction waste dust and silt that can be washed by the dust reduction mechanism 6 to enter the storage box 3 for filtration, and at the same time, it is convenient for the recovery and treatment of sewage.

[0031] At the higher end of the screening box body 2, a crusher housing 1 is welded and installed. A protective part 13 is arranged on the crusher housing 1. Welding plates 11 and fixed side plates 12 are respectively welded and installed outside the crusher housing 1. Inside the crusher housing 1, a protective mesh plate 26 is fixedly installed at the position of the dust reduction mechanism 6, and the aperture of the protective mesh plate 26 is smaller than the aperture of the D sieve plate layer 25. The setting of the protective mesh plate 26 plays a protective role for the dust reduction mechanism 6, and at the same time, it assists the construction waste to fall down relying on the inclined surface of the protective mesh plate 26 after being crushed.

[0032] Moreover, a crushing mechanism 5 is installed inside the crusher housing 1. The crushing mechanism 5 includes a fixed roller 52 fixedly installed on one side of the protection part 13, a driving roller 51 fixedly installed on one side of the fixed roller 52 through a bearing, a driven roller 53 fixedly installed at the bottom of the fixed roller 52 and the driving roller 51 through a bearing, and a driving motor 54 fixedly installed on the fixed side plate 12 for driving the driving roller 51 and the driven roller 53. The driving motor 54 drives the driving roller 51 and the driven roller 53 to rotate through a pulley group 55. The fixed roller 52 is fixedly installed inside the crusher housing 1, and the driven roller 53 is installed at the bottom between the driving roller 51 and the fixed roller 52. After the construction waste is crushed once by the driving roller 51 and the fixed roller 52, it is then crushed a second time by the driving roller 51 and the driven roller 53 or the fixed roller 52 and the driven roller 53, thereby ensuring the completeness of the crushing of the construction waste.

[0033] At the bottom of the crushing mechanism 5, a dust reduction mechanism 6 is fixedly installed inside the crusher housing 1. The dust reduction mechanism 6 includes a plurality of groups of water spray pipes 63 installed through the crusher housing 1, a fixed pipe 64 butt-jointed and installed at the end of the water spray pipe 63, a delivery pump 65 fixedly installed on the welding plate 11, a connecting pipe 62 butt-jointed and installed between the delivery pump 65 and the fixed pipe 64, and an external hose 61 butt-jointed and installed at the input port of the delivery pump 65. By connecting an external water source through the dust reduction mechanism 6, water is sprayed inside the crusher housing 1, which is convenient for dust reduction inside the crusher housing 1 during the crushing process, and at the same time, other smaller particles of construction waste are washed, causing them to fall into the storage box 3 for filtration. Moreover, the dust reduction mechanism 6 can also wash and treat the sludge that is likely to exist in the construction waste, ensuring the completeness of the treatment of the construction waste and achieving the effect of dust reduction at the same time.

[0034] First, the crushing mechanism 5 installed inside the crusher housing 1 crushes the construction waste, causing it to fall into the screening box body 2. During the crushing process, after the construction waste is crushed once by the driving roller 51 and the fixed roller 52, it is then crushed a second time by the driving roller 51 and the driven roller 53 or the fixed roller 52 and the driven roller 53, thereby ensuring the completeness of the crushing of the construction waste. By connecting an external water source through the dust reduction mechanism 6, water is sprayed on the crushed construction waste inside the crusher housing 1, which is convenient for dust reduction inside the crusher housing 1 during the crushing process, and at the same time, other smaller particles of construction waste are washed, causing them to fall into the storage box 3 for filtration. Moreover, the dust reduction mechanism 6 can also wash and treat the sludge that is likely to exist in the construction waste. During the rolling process of the crushed construction waste according to its own weight, the A sieve plate layer 22, B sieve plate layer 23, C sieve plate layer 24, and D sieve plate layer 25 are arranged to screen the construction waste through different aperture sieves, causing it to fall into the corresponding storage box 3.

[0035] All the technical features in this embodiment can be freely combined according to actual needs.

[0036] The above embodiments are preferred implementation solutions of the present utility model. In addition, the present utility model can also be implemented in other ways. Any obvious substitution without departing from the concept of the technical solution is within the protection scope of the present utility model.
