Two rotating shafts 2 arranged parallel to each other are rotatably installed in the box body 1. A plurality of crushing rods 21 are fixedly installed on both rotating shafts 2. Rotating pins are damping rotatably installed on a plurality of crushing rods 21, and crushing blocks 22 are radially fixedly installed at both ends of the rotating pins. The plurality of crushing rods 21 on the two rotating shafts 2 are arranged staggeredly. A motor 3 is fixedly installed on one side of the box body 1 close to the dust collection box 4. A driving gear 31 is fixedly sleeved on the output shaft of the motor 3. One ends of the two rotating shafts 2 close to the dust collection box 4 extend outside the dust collection box 4 and are respectively fixedly sleeved with driven gears 32. The driving gear 31 meshes with the two driven gears 32, capable of driving the two rotating shafts 2 to rotate. The box body 1 and the dust collection box 4 are communicated through the connecting pipe 401. A circular opening is formed on one side of the dust collection box 4 away from the box body 1. A net plate is fixedly installed in the circular opening. A spherical filter plate 43 adapted to the circular opening is fixedly installed in the dust collection box 4. A horizontal shaft 41 is rotatably installed on the dust collection box 4. One end of the horizontal shaft 41 is axially fixedly connected to the output shaft of the motor 3. The end of the horizontal shaft 41 away from the motor 3 extends into the spherical filter plate 43 and is fixedly sleeved with a fan blade 42, capable of controlling the fan blade 42 to discharge the air in the dust collection box 4 outwards through the circular opening when the motor 3 works, so as to be able to extract and collect the dust raised in the box body 1 into the dust collection box 4 under the action of the connecting pipe 401;

[0042] Two connecting cylinders arranged parallel to each other are fixedly installed on one side of the box body 1 and the dust collection box 4 close to each other. Two mounting cylinders are fixedly installed at the bottom of one side of the dust collection box 4 away from the box body 1. Two mounting cylinders, two connecting cylinders and two support shafts 5 arranged parallel to each other are rotatably installed in the box body 1. Spiral blades 51 are fixedly installed on both support shafts 5, capable of discharging the construction waste crushed in the box body 1 through the dust collection box 4 when the support shafts 5 rotate, and at the same time discharging the dust collected in the dust collection box 4 synchronously. The two rotating shafts 2 and the two support shafts 5 both extend to the right side of the box body 1 and are respectively fixedly sleeved with belt pulleys 52. The same belt 53 is drivingly connected to the two belt pulleys 52 located on the same vertical axis, in order to be able to provide driving force for the support shafts 5 when the rotating shafts 2 rotate. The sieve plate 13 is fixedly installed in the box body 1 and is located at a position between the lower side of the movement range of the crushing blocks 22 and the movement track of the spiral blades 51.

[0043] Specifically, a support bar is fixedly installed on the inner wall of the mounting cylinder away from the dust collection box 4. The left end of the support shaft 5 is rotatably installed on the support bar, capable of providing support for the support shaft 5 while reducing the influence on the discharge of materials.

[0044] Specifically, in order to be able to divert the materials entering the box body 1 and avoid the situation of excessive concentration in the crushing areas of the crushing rods 21 and the crushing blocks 22, two diversion plates 12 are fixedly installed on the inner walls of both sides of the box body 1, and the two diversion plates 12 are respectively located directly above the corresponding rotating shafts 2.

[0045] Specifically, in order to avoid the phenomenon of material accumulation on the diversion plate 12, the top side of the diversion plate 12 is arranged in an arc shape.

[0046] Specifically, in order to be able to keep the distance between the sieve plate 13 and the movement trajectories of the crushing blocks 22 at a relatively close position all the time, so as to be able to greatly reduce the phenomenon of material accumulation on the sieve plate 13 and the occurrence of crushing blind spots, the sieve plate 13 is arranged in a W shape.

[0047] Specifically, in order to be able to improve the discharging efficiency of the spiral blade 51 and at the same time avoid the situation where the materials on the inner wall of the bottom of the box body 1 cannot be discharged normally, the inner wall of the bottom of the box body 1 is arranged in a W shape, and the spiral blade 51 is located at the lowest point of the inner wall of the bottom of the box body 1.

[0048] Working principle: First, connect the power supply and start the motor 3. Pour the construction engineering materials or garbage to be crushed into the box body 1 from the feed hopper 11. Under the action of the diversion plate 12, it is diverted, so as to avoid the phenomenon of material concentration. The motor 3 controls the rotation of the two rotating shafts 2 through the driving gear 31 and the two driven gears 32, so that the crushing rods 21 and the crushing blocks 22 rotate around the corresponding rotating shafts 2 as the center. Since the crushing blocks 22 are rotationally installed on the crushing rods 21 through the rotating pins with damping, the crushing efficiency can be effectively improved. The crushed part is screened under the action of the sieve plate 13. Since the position below the movement trajectory of the crushing blocks 22 is relatively close to the sieve plate 13, the materials on the sieve plate 13 can be stirred, which can not only improve the screening efficiency of the sieve plate 13, but also crush the parts that are not completely crushed on the sieve plate 13 again, effectively ensuring the crushing effect.

[0049] While the motor 3 is working, it drives the fan blade 42 to rotate rapidly through the horizontal shaft 41, so as to be able to extract the air in the dust collection box 4 and extract the dust raised in the box body 1 into the dust collection box 4 under the action of the connecting pipe 401, which can effectively avoid the phenomenon of dust pollution during the crushing process. The dust entering the dust collection box 4 is intercepted under the action of the spherical filter plate 43, so that the dust is collected in the dust collection box 4. While the rotating shaft 2 rotates, it can control the support shaft 5 to drive the spiral blade 51 to convey the crushed part in the box body 1 to the dust collection box 4 through the connecting cylinder and discharge it together with the dust collected in the dust collection box 4 from the installation cylinder position.

[0050] The above has introduced in detail an environmentally friendly crushing device for construction engineering provided by the present utility model. Specific embodiments are applied in this article to elaborate on the principle and implementation manner of the present utility model. The description of the above embodiments is only used to help understand the method and its core idea of the present utility model. It should be noted that for those of ordinary skill in the art of this technology, without departing from the principle of the present utility model, several improvements and modifications can still be made to the present utility model, and these improvements and modifications also fall within the protection scope of the claims of the present utility model.
