[0018] like Figs. 1-3 This invention relates to a double-toothed roll crusher with easily adjustable toothed roll spacing. The crusher body includes a first crushing roll 11 and a second crushing roll 12 that are parallel to each other. The first crushing roll 11 is driven by a first drive motor 13, and the second crushing roll 12 is driven by a second drive motor 14. It includes two spaced-apart bases 1, each with a top seat 2. Both ends of the bases 1 and top seats 2 are baffles 20. The connecting shafts at both ends of the first crushing roll 11 are rotatably connected to movable bearing seats 3, and the connecting shafts at both ends of the second crushing roll 12 are rotatably connected to fixed bearing seats 4. The movable bearing seat 3 and the fixed bearing seat 4 on the same side are located between the base 1 and the top seat 2. The movable bearing seat 3 is slidably disposed with the base 1 and the top seat 2. An adjusting screw 7 is provided between the two opposite sides of the movable bearing seat 3 and the fixed bearing seat 4. An adjusting nut 8 and a fixing nut 21 are connected to the adjusting screw 7. A fixing mechanism is provided on the side of the movable bearing seat 3. One end of the adjusting screw 7 is threadedly connected to the fixed bearing seat 4 and fixed by the fixing nut 21. The other end of the adjusting screw 7 is slidably connected to the movable bearing seat 3.

[0019] Specifically, the adjustment process is as follows: turn the adjusting nut 8 to move it to the right. Since the adjusting nut 8 and the movable bearing seat 3 are connected by a smooth hole, the adjusting nut can slide inside the movable bearing seat 3. Move the movable bearing seat 3 to the right to adjust the distance between the crushing roller 11 and the crushing roller 22. After adjustment, the movable bearing seat 3 is fixed by the fixing mechanism to prevent it from moving.

[0020] Furthermore, the fixing mechanism includes a fixing plate 9, which is fixed to the side of the movable bearing seat 3. An adjusting screw 10 is connected to the end face of the fixing plate 9 away from the movable bearing seat 3, and the adjusting screw 10 passes through the guard plate.
