The first oil cylinder and the second oil cylinder are respectively hinged to the base. The piston rod of the first oil cylinder is hinged to the first side housing, and the piston rod of the second oil cylinder is hinged to the second side housing. Bearing seats are respectively arranged on the front and rear sides of the base. Both ends of the crushing rotor assembly respectively pass through the middle housing and are rotatably matched with the two bearing seats correspondingly. A long sieve plate is arranged on the first side housing, and a short sieve plate is fixed on the second side housing. When the first side housing and the second side housing respectively turn inward and lean against both sides of the middle housing, the base, the first side housing, the middle housing, and the second side housing form a hollow housing, and the long sieve plate and the short sieve plate cooperate to form a crushing chamber arranged on the outer periphery of the crushing rotor assembly. A feed inlet is arranged on the middle housing, and the feed inlet is communicated with the crushing chamber. When the first side housing and the second side housing respectively turn outward and away from the middle housing, the crushing rotor assembly, the long sieve plate, and the short sieve plate are all exposed. One end of the crushing rotor assembly is connected to the motor through a speed reducer. The first oil cylinder and the second oil cylinder are respectively connected to the pump station.

[0007] Further, there are two maintenance openings provided on the first side housing, and quick-opening maintenance doors are provided on the maintenance openings.

[0008] Further, the pumping station is a mobile pumping station.

[0009] Further, it further includes adjusting rods. The upper end of the long sieve plate is hinged to the upper end of the first side housing. One ends of the two adjusting rods are respectively hinged to the middle of the long sieve plate. The other ends of the two adjusting rods both pass through the first side housing to the left and are connected to the driving device. The two adjusting rods are aligned front and back.

[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0011] The present utility model provides hydraulic power for the first oil cylinder and the second oil cylinder through the pumping station, which is used to flip the first side housing and the second side housing, so that most of the components of the crushing rotor assembly and the crushing chamber can be exposed. With such a setting, when it is necessary to remove or replace internal components and perform maintenance on the equipment inside, the operation is convenient, there is no need to remove the upper feeding pipe, the maintenance workload is reduced, and the work efficiency is improved.
