[0026] 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.

[0027] See also Figures 1 to 5 In an embodiment of the present invention, a construction waste treatment device includes a shell 1 and a crushing structure 4; the crushing structure 4 is installed in the shell 1, and the crushing structure 4 includes crushing rollers 43 symmetrically installed inside the shell 1, and auxiliary plates 3 located on the surfaces of the crushing rollers 43 are relatively installed in the shell 1, and the surface of the auxiliary plate 3 is inclined relative to the vertical plane, and one end of the auxiliary plate 3 is inserted between two crushing rollers 43, and a plurality of auxiliary hammers 32 are installed on the auxiliary plate 3; auxiliary grooves 21 are installed on both sides of the shell 1, and a telescopic structure 2 is installed in the auxiliary groove 21, and a finger support frame 31 is installed on the outer side of the auxiliary plate 3, and the two ends of the support frame 31 are respectively connected to the telescopic structures 2 on both sides;

[0028] The telescopic structure 2 is used to drive the auxiliary plate 3 to reciprocate along the axis direction of the crushing roller 43;

[0029] The housing 1 is provided with a transmission structure 7 , which is respectively connected to the telescopic structures 2 on both sides of the housing 1 , and the transmission structure 7 synchronously controls the telescopic structures 2 on both sides at the same time.

[0030] The device uses a pair of crushing rollers 43 that can rotate relative to each other in the shell 1. When working, construction waste falls on the crushing rollers 43. As the crushing rollers 43 rotate toward the middle, the construction waste is squeezed and crushed until the crushed particles are smaller than the distance between the two crushing rollers 43 and can fall. At the same time, the device is provided with a relative auxiliary plate 3 on the surface of the crushing roller 43. A plurality of auxiliary hammers 32 with pointed ends are installed on one side of the auxiliary plate 3 located in the middle of the shell 1. When the construction waste is too large or the position is just stuck, resulting in the two crushing rollers 43 being unable to rotate relative to each other, the telescopic structures 2 located on both sides of the shell 1 act at the same time, driving the auxiliary plates 3 through the support frame 31, so that the two auxiliary plates 3 move rapidly toward the middle at the same time to hit the stuck construction waste, so as to solve the problem of the crushing roller 43 being stuck.

[0031] The auxiliary hammer 32 that repeatedly strikes the middle can cause the stuck construction waste to move to one side and escape from the stuck position, and can also partially crush the waste through the clamping of the two crushing plates, so that the subsequent crushing work is easier to carry out normally after the volume is reduced. In addition, the auxiliary plate 3 is tilted upward and the bottom of the auxiliary plate 3 extends downward and inserts between the two crushing rollers 43. While pushing the waste to move, the waste will also be impacted obliquely upward, causing the waste to bounce or roll, thereby maximally changing the contact angle between the waste and the crushing roller 43 to avoid the problem of continued jamming in the future.

[0032] When the device encounters the problem of equipment jamming caused by waste materials, the stuck waste materials can be quickly resolved without manual processing, which significantly improves the user experience of the double-roll crusher, reduces the demand for manpower, and improves the efficiency of use.

[0033] As another embodiment of the present invention, please refer to Figure 1 , Figure 4 and Figure 5 The telescopic structure 2 includes a scissor mechanism 24 located in the auxiliary groove 21, and the scissor mechanism 24 is composed of a plurality of connecting rods 241 connected in an X-shaped cross-connection. The two ends of the scissor mechanism 24 are respectively connected to a sliding plate 22, and the sliding plate 22 is connected to the support frame 31. The plurality of connecting rods 241 of the scissor mechanism 24 form a plurality of diamond structures connected to each other, wherein the length of the entire scissor mechanism 24 can be changed by changing the internal angle of any diamond, so as to achieve the purpose of controlling the extension and retraction of the sliding plate 22. The scissor mechanism 24 is not a restrictive structure, and the structure using a screw rod with a threaded barrel, a linear motor, a crank rocker structure, or directly using a hydraulic rod, etc., also conforms to the structural design of the present device.

[0034] See also Figure 1 , Figure 4 and Figure 5, a plurality of transverse slide bars 23 are installed in the auxiliary groove 21, a through hole 221 is formed on the sliding plate 22, and the slide bars 23 pass through the corresponding through holes 221, a horizontal slide groove 211 is formed on the auxiliary groove 21, and the support frame 31 passes through the slide groove 211. The slide bars 23 pass through the through hole 221 on the sliding plate 22 to limit the position of the sliding plate 22 and enhance the stability of the sliding plate 22. When the auxiliary plate 3 collides with the construction waste, different torques may be generated on the auxiliary plate 3 due to the instability of the force position. Therefore, by enhancing the stability of the sliding plate 22, the auxiliary plate 3 can be prevented from twisting after long-term use.

[0035] See also Figure 1 , Figure 4 and Figure 5 A symmetrical threaded barrel 242 is installed in the middle of the scissor mechanism 24, and a bidirectional screw 25 is rotatably installed in the auxiliary groove 21. The threaded barrel 242 is respectively located at both ends of the bidirectional screw 25 and is threadedly engaged with the bidirectional screw 25. One end of the bidirectional screw 25 passes through the housing 1. The bidirectional screw 25 cooperates with the threaded barrel 242. By rotating the bidirectional screw 25, the two threaded barrels 242 can be synchronously moved closer or farther away, and the threaded barrel 242 is used to change the shape of the scissor mechanism 24, thereby controlling the movement of the auxiliary plate 3.

[0036] See also Figure 1 , Figure 3 and Figure 5 The transmission structure 7 includes a mounting groove 11 located on the surface of the housing 1. The mounting groove 11 is U-shaped. A rotating shaft 72 is installed at the corner of the mounting groove 11. One end of the bidirectional screw 25 is inserted into the mounting groove 11. A pulley 74 is installed on both the rotating shaft 72 and the mounting groove 11. The pulley 74 is connected through a transmission belt 73. A primary motor 71 is installed on the mounting groove 11. The primary motor 71 is connected to the pulley 74. The mounting groove 11 is used to protect the internal transmission belt 73 and the pulley 74. The connection is made through the pulley 74 on the rotating shaft 72, so that the two bidirectional screws 25 on both sides of the housing 1 can rotate synchronously, so that the sliding plates 22 on both sides can be ensured to move synchronously during the sliding process of the auxiliary plate 3.

[0037] See also Figures 1 to 4, a plurality of crushing hammers 431 are installed on the surface of the crushing roller 43, one end of the crushing roller 43 is connected to a driven gear 41 located outside the housing 1, a transmission gear 42 is rotatably installed on the housing 1, the transmission gear 42 is located between the driven gears 41 and meshed with the driven gears 41, a secondary motor 44 is installed on the housing 1, and the secondary motor 44 is connected to the crushing roller 43. The rotation of the crushing roller 43 drives the crushing hammer 431 to squeeze and crush the construction waste, the transmission gear 42 is connected between the driven gears 41, and the number of linearly connected transmission gears 42 is an even number, the secondary motor 44 drives one of the crushing rollers 43 to rotate, and the other crushing roller 43 rotates in the opposite direction synchronously, and the construction waste is pressurized and crushed into the gap between the two crushing rollers 43.

[0038] See also Figure 1 and Figure 3 , an inclined screen 5 is installed in the shell 1, a plurality of vibration motors 51 are installed inside the shell 1, the vibration motors 51 are connected to the screen 5, an inclined guide plate 6 is installed inside the shell 1, the guide plate 6 is located at one end of the shell 1 away from the crushing structure 4, and the inclination direction of the guide plate 6 is opposite to the inclination direction of the screen 5. The screen 5 can screen the broken waste fragments. Since the crushing process is uncontrollable, the broken waste fragments are of various sizes, and there will be a lot of powder mixed in them. Therefore, the vibration motor 51 is used to control the vibration of the screen 5 to screen the waste fragments. The fragments with a particle size within a certain range remain on the screen 5, and other powders and residues pass through the screen 5 and fall down and are discharged through the guide plate 6.

[0039] See also Figures 1 to 3 The shell 1 is provided with a feed port 12 pointing to the middle area of ​​the two crushing rollers 43, a discharge port 13 located on one side of the screen 5, a slag discharge port 15 located on one side of the guide plate 6, and a plurality of support legs 14 are installed outside the shell 1. Construction waste enters the shell 1 from the feed port 12 and falls between the two crushing rollers 43. After crushing and screening, the fragments with qualified particle size are discharged from the discharge port 13, and the remaining residues are discharged from the slag discharge port 15. The support legs 14 are used to provide support for the shell 1.

[0040] The working principle of the present invention is:

[0041] The device is provided with two symmetrical crushing rollers 43 inside the shell 1, which squeeze and crush the construction waste through relative rotation. At the same time, a slidable auxiliary plate 3 is installed above the crushing roller 43, and multiple groups of auxiliary hammers 32 are installed on the auxiliary plate 3, and one end of the auxiliary plate 3 inserted between the two crushing rollers 43 is inclined toward the middle area. When a large piece of construction waste jams the crushing roller 43, the auxiliary plate 3 is driven by the telescopic structure 2 on both sides to impact the construction waste, which can cause the construction waste to move and partially crush, change the current jamming situation, and restore the crushing roller 43 to normal use. The device can solve the jamming problem that may occur in the double-roll crusher, and can restore the normal use of the equipment without manual processing, which significantly improves the user experience.
