The output end of the synchronous reversing gearbox is fixedly connected to the other end of the main shaft of another crushing roll.

[0007] Preferably, the crushing teeth of the tooth ring on the crushing roll are in the shape of an eagle's beak.

[0008] Further preferably, the tooth rings on two adjacent crushing rolls are arranged in a cross pattern.

[0009] Preferably, the comb tooth plate is provided with perforations, and the side plates of the frame are provided with a plurality of threaded holes arranged in parallel. One end of the bolt passes through the perforation and is screwed into one of the threaded holes.

[0010] More preferably, both ends of the main shaft are mounted on the frame through eccentric cups.

[0011] The beneficial effects of the present utility model are as follows:

[0012] In the present utility model, each motor drives a group of crushing rolls. The transmission mode is stable, reliable, and low in energy consumption, and can provide strong torque. The comb tooth plate is designed to be a structure that can be adjusted up and down to change the gap between the comb teeth and the tooth rolls, so as to better realize the combing function of the material. The distance between two adjacent crushing rolls can be adjusted, so as to realize adjustable discharge particle size. After the multi-roll crusher with the above characteristics is applied in the crushing field, not only is the production capacity high, but also the particle size of the crushed material is uniform and adjustable, creating considerable economic benefits for the market.

[0019] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the drawings in the embodiments of the present utility model. Many specific details are set forth in the following description in order to fully understand the present utility model, but the present utility model can also be implemented in other ways different from those described herein. Those skilled in the art can make similar generalizations without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0020] As Figure 1As shown in the figure, this embodiment provides a new type of double-tooth roll coal slime crusher, which includes two motors 1, four crushing rolls and a frame. The four crushing rolls are arranged side by side on the frame, and the two motors 1 are respectively arranged at two ends of the frame. Among them, the rotation directions of any two adjacent crushing rolls among the four crushing rolls are opposite, so that the two adjacent crushing rolls jointly crush the material. The motor 1 is used to drive the crushing roll to rotate. Specifically, one motor 1 controls the rotation of the two adjacent crushing rolls located in the upper part, and the other motor 1 controls the rotation of the two adjacent crushing rolls located in the lower part.

[0021] In this embodiment, the crusher further includes a hydraulic coupling 2, a speed reducer 3, a coupling 4 and a synchronous reversing gearbox 11. The output shaft of the motor 1 is fixedly connected to the input end of the hydraulic coupling 2, the output end of the hydraulic coupling 2 is fixedly connected to the input end of the speed reducer 3, the output end of the speed reducer 3 is fixedly connected to the input end of the coupling 4, the output end of the coupling 4 is fixedly connected to one end of the main shaft 8 of the crushing roll, and the other end of the main shaft 8 passes through the frame and is fixedly connected to the input end of the synchronous reversing gearbox 11. The output end of the synchronous reversing gearbox 11 is fixedly connected to the other end of the main shaft 8 of another crushing roll. Through the transmission of the above-mentioned various transmission components, the rotation of the crushing roll is finally stabilized. In addition, both ends of the main shaft 8 are installed on the frame through eccentric cups 6 (the eccentric cups 6 can use mature products on the market, and the eccentric cups 6 are installed on the bearing seats 5), and the width between two adjacent crushing rolls is adjusted by rotating the eccentric cups 6.

[0022] A comb tooth plate 10 is provided on the side plate 7 of the frame, and the gap between the comb tooth plate 10 and the crushing roll can be adjusted. Specifically, the comb tooth plate 10 is provided with through holes, and the side plate 7 of the frame is provided with a plurality of threaded holes arranged side by side. One end of the bolt passes through the through hole and is screwed into one of the threaded holes. By installing the comb tooth plate 10 in combination with different threaded holes, the installation height of the comb tooth plate 10 is adjusted, thereby changing the gap between the comb teeth and the crushing roll, so as to better realize the comb tooth function of the material.

[0023] In this embodiment, the crushing teeth of the tooth ring 9 on the crushing roll are eagle beak-shaped. At the same time, the tooth ring 9 is spirally arranged on the crushing roll, and the tooth rings 9 on two adjacent crushing rolls are cross-arranged.
