[0025] See also Figure 1-4 The utility model provides a technical solution: a construction waste crushing device, including a crushing table 1, a crushing trough 2 is opened on the top of the crushing table 1, two crushing rollers 3 are rotatably connected inside the crushing trough 2, one end of the two crushing rollers 3 rotates and penetrates one side of the crushing table 1, the outer surfaces of the two crushing rollers 3 are fixedly sleeved with gears 4, the outer surfaces of the two gears 4 are meshed and connected, and an automatic material dividing component is provided inside the crushing trough 2.

[0026] Furthermore, the automatic material distribution component includes a rotating column 13, the two ends of which are rotatably connected to the two sides of the inner wall of the crushing trough 2, the outer surface of the rotating column 13 is fixedly connected with four flaps 14, the interior of the four flaps 14 is provided with a through groove 15, the inner walls of the four through grooves 15 are fixedly connected with a first filter screen 16, a filter groove 17 is provided on the bottom surface of the inner wall of the crushing trough 2, the inner wall of the filter groove 17 is fixedly connected with a second filter screen 18, and a connecting groove 19 is provided on one side of the inner wall of the crushing trough 2.

[0027] Furthermore, a second collecting trough 11 is provided on one side of the crushing table 1, and the interior of the second collecting trough 11 is communicated with the interior of the connecting trough 19, and the inner wall of the second collecting trough 11 is slidably connected to the second collecting box 12. A first collecting trough 9 is provided on one side of the crushing table 1, and the interior of the first collecting trough 9 is communicated with the interior of the filter trough 17, and the inner wall of the first collecting trough 9 is slidably connected to the first collecting box 10. A connecting column 7 is rotatably connected to one side of the crushing table 1, and the end of the connecting column 7 close to the rotating column 13 rotates through the interior of the crushing trough 2 and is fixedly connected to one end of the rotating column 13. The connecting column 7 is transmission-connected to the outer surface of the corresponding crushing roller 3 with a belt 8. A fixed block 5 is fixedly connected to one side of the crushing table 1, and a motor 6 is fixedly connected to one side of the fixed block 5. The output end of the motor 6 is fixedly connected to one end of the corresponding crushing roller 3.

[0028] Furthermore, when the staff uses the device, the motor 6 is started, and the motor 6 drives the crushing roller 3 connected thereto to rotate. Then, through the meshing action of the two gears 4, the two crushing rollers 3 rotate relative to each other. At the same time, through the transmission of the belt 8, the connecting column 7 also rotates synchronously. Then the connecting column 7 drives the rotating column 13 to rotate, and then the rotating column 13 drives the four flaps 14 to rotate, and when the four flaps 14 rotate, they will respectively make rotational contact with the top surface of the second filter 18.

[0029] Furthermore, the construction waste is poured into the crushing trough 2. After the construction waste is crushed by the two crushing rollers 3, the crushed construction waste will fall on the flap 14. Then, the crushed construction waste is rotated and screened by the cross flap composed of four flaps 14. The smaller granular waste materials will pass through the inside of the first filter screen 16 and fall into the inside of the second filter screen 18, thereby entering the inside of the first collecting box 10. Then, the larger waste construction materials will be flipped by the flap 14 to the inside of the connecting trough 19, and then enter the inside of the second collecting box 12, so that the material screening of the crushed construction waste can be completed.

[0030] Furthermore, through the rotating screening design of the flap 14, after the crushed garbage material is filtered on the second filter 18, the larger garbage material will automatically enter the interior of the connecting groove 19, thereby automatically screening the construction waste material. At the same time, through the setting of the first filter 16, the flap 14 can be rotated to screen the garbage material, and the fine garbage material can be preliminarily screened, thereby improving the secondary screening efficiency of the second filter 18. In this way, not only the crushing device has the function of automatically screening material collection, but also strengthens the screening function of fine garbage materials, thereby improving the practicality of the crushing device.

[0031] Furthermore, by contacting the top surface of the second filter screen 18 when rotating, the flap 14 can clean the top surface of the second filter screen 18 to prevent more fine particles from being blocked inside the second filter screen 18, thereby enabling the second filter screen 18 to better filter smaller garbage particles.

[0032] Working principle: When the staff uses the device, the motor 6 is started, and the motor 6 drives the crushing roller 3 connected thereto to rotate. Then, through the meshing action of the two gears 4, the two crushing rollers 3 rotate relative to each other. At the same time, through the transmission of the belt 8, the connecting column 7 also rotates synchronously. Then the connecting column 7 drives the rotating column 13 to rotate, and then the rotating column 13 drives the four flaps 14 to rotate, and the four flaps 14 will respectively make rotational contact with the top surface of the second filter 18 when rotating. Then, the construction waste is poured into the inside of the crushing trough 2. After the construction waste is crushed by the two crushing rollers 3, the crushed construction waste will fall on the flap 14, and then through the combination of the four flaps 14 The cross flap is used to perform rotational screening on the crushed construction waste. Smaller granular waste materials will pass through the inside of the first filter 16 and fall into the inside of the second filter 18, thereby entering the inside of the first collection box 10. Then, larger waste construction materials will be flipped by the flap 14 to the inside of the connecting groove 19, and then enter the inside of the second collection box 12, so that the crushed construction waste can be screened. At the same time, the flap 14 will contact the top surface of the second filter 18 when rotating, so that the flap 14 can clean the top surface of the second filter 18 to prevent more fine granular materials from being blocked in the inside of the second filter 18, so that the second filter 18 can better filter smaller garbage granular materials.

[0033] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments.
