[0003] Among them, commonly used building materials are cement bricks, which are mainly used in construction applications such as building walls, foundations, and retaining walls.
[0004] When cement bricks are used in construction, if you are not careful, they will be damaged by collisions. These damaged cement brick wastes are generally crushed into aggregates for later recycling. Therefore, a crushing device for construction cement brick waste is needed.
[0005] At present, the existing crushing device for construction cement brick waste will generate a lot of light dust during the crushing process. The light dust will fly from the feeding pipe into the working environment, thereby causing pollution to the working environment, greatly reducing the dust resistance of the feeding pipe on the crushing device for construction cement brick waste.
[0006] In addition, the existing crushing devices for construction cement brick waste have crushing boxes that are mostly fixedly installed on the ground in the working environment. If they are not used for a long time, the crushing box as a whole may occupy the working environment space, thereby reducing the flexible mobility and adaptability of the crushing devices for construction cement brick waste.
[0007] The above problems are widespread and urgently need to be improved. Utility Model Content

DETAILED DESCRIPTION
[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0028] Reference Figure 1-5A building material crushing device comprises a crushing box 1, on which a first crushing roller group 11 and a second crushing roller group 12 are arranged, a slag discharge pipe 2 and a bottom support plate 3 are arranged at the bottom of the crushing box 1, a valve 21 is arranged on the slag discharge pipe 2, a mounting plate 31 is arranged on the bottom support plate 3, a moving wheel 32 is arranged on the mounting plate 31, a box cover 5 is arranged on the upper cover of the crushing box 1, a bolt 51 and a feeding pipe 6 are arranged on the box cover 5, and a secondary dust suction pipe 61 is connected to the feeding pipe 6, and the box The cover 5 is provided with a dust box 8, a suction pump 9, and a control switch 52. The suction pump 9 is provided with a suction pipe 91 and an exhaust pipe 92. The dust box 8 is provided with a box cover plate 81 and a main dust suction pipe 7. The main dust suction pipe 7 is connected with a vertical branch suction pipe 71. The box cover plate 81 is provided with a screw pin 82. The crushing box 1 is provided with a push handle 4. The first crushing roller group 11 and the second crushing roller group 12 are both related structures of the crushing device, which are prior art and have their own motors. Some existing structures are not drawn and marked, and there is no need to repeat them.
[0029] In detail, the auxiliary dust suction pipe 61 is connected to the vertical branch suction pipe 71, and the main dust suction pipe 7 and the suction pipe 91 are both connected to the inner cavity of the dust storage box 8. The auxiliary dust suction pipes 61 are divided into two symmetrical groups on the left and right, each group of three are arranged vertically and connected to the inner cavity of the feeding pipe 6. The symmetrical three vertical auxiliary dust suction pipes 61 improve the extraction efficiency of light dust.
[0030] Furthermore, there are two suction pumps 9 that are symmetrical on the left and right, and the control switch 52 is electrically connected to the two suction pumps 9. Two buttons are preset on the control switch 52, which can control the opening and closing of the two suction pumps 9 at the same time.
[0031] Furthermore, the box cover 81 is arranged at the front end of the dust box 8, and the screw pin 82 passes through the box cover 81 and is threadedly connected to the dust box 8. When the dust box 8 is full of light dust, first turn the screw pin 82 counterclockwise and remove it, and then rotate the box cover 81 downward to open it, so that the light dust in the dust box 8 can be cleaned.
[0032] A dustproof net is preset in the dust storage box 8 to prevent light dust from entering the suction pump 9.
[0033] In more detail, a protective net 611 is provided in the inner cavity of the auxiliary dust suction pipe 61. The protective net 611 is a metal mesh structure. When the auxiliary dust suction pipe 61 sucks light dust, it can prevent the thrown-in construction cement brick waste from entering the auxiliary dust suction pipe 61 to avoid blockage.
[0034] In general, the moving wheels 32 are installed at the lower end of the mounting plate 31 . There are four moving wheels 32 symmetrically arranged. The moving wheels 32 are universal brake casters, which are durable and have high bearing capacity.
[0035] The push handle 4 is provided with two positioning grip grooves 41 symmetrically arranged front and back and having an inner arc-shaped cross section in top view, so that the push handle 4 can be stably held and pushed by both hands.
[0036] Finally, the inner groove wall of the positioning grip groove 41 is provided with an anti-skid layer 42 . The anti-skid layer 42 is made of elastic fiberglass material and has a thickness of eight to ten millimeters. The elastic fiberglass material has excellent elastic anti-skid properties.
[0037] Working method: Start the first crushing roller group 11 and the second crushing roller group 12, and then put the construction cement brick waste into the crushing box 1 through the feeding pipe 6. The construction cement brick waste will be crushed by the first crushing roller group 11 and the second crushing roller group 12, and the crushed aggregate debris will be discharged through the slag discharge pipe 2. At this time, press the left button on the control switch 52, and the suction pumps 9 on both sides will start, which will form a suction force on each auxiliary dust suction pipe 61. During the crushing process, light dust flies upward into the feeding pipe 6 and will be fully and quickly extracted by each auxiliary dust suction pipe 61. The extracted light dust enters the dust storage box 8 through the vertical sub-suction pipe 71 and the main dust suction pipe 7 for storage, so as to avoid the light dust directly flying into the working environment to cause pollution, thereby improving the dust resistance of the feeding pipe 6 on the crushing device for construction cement brick waste.
[0038] Moreover, if the crushing box 1 is not used for a long time, first loosen the brake of the moving wheel 32, then hold the push handle 4, and use the moving wheel 32 to conveniently move the crushing box 1 to the corner of the working environment space, and then brake the moving wheel 32 to position it, so as to avoid the crushing box 1 directly occupying the working environment space as a whole, thereby improving the flexible mobility and adaptability of the crushing device for construction cement brick waste.
[0039] In addition, when pushing, both hands can hold the positioning grip grooves 41 on both sides, and the anti-skid layer 42 will contact the skin of both hands, which greatly improves the anti-skid stability of the hand holding the push handle 4 when pushing the crushing box 1.
[0040] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
