The push head oil cylinder and the material lifting oil cylinder are controlled by a hydraulic control system arranged in the power unit. The hydraulic control system includes a first oil pump, a second oil pump, a linkage position, and a split position. In the linkage position, the hydraulic control system controls the first oil pump and the second oil pump to jointly supply oil to the push head oil cylinder. In the split position, the hydraulic control system controls the first oil pump to supply oil to the push head oil cylinder and controls the second oil pump to supply oil to the material lifting oil cylinder.

[0003] When the mobile garbage compression equipment is in operation, garbage first enters the interior of the equipment, and then the push head extrudes and pushes the garbage into the compression chamber. The fixed broken knife inside the equipment cuts open the garbage bag to break the bag. However, there are problems with this design. Since the broken knife is fixedly installed, the gap below the broken knife is small, which makes it difficult for large-volume bagged garbage to enter the compression chamber, and other compressed garbage is prone to rebound.

[0007] As a further improvement of the utility model, the fixed knife seat includes two left-right symmetrical fixed plates, a transverse bolt is arranged between the two fixed plates, the bolt is sequentially arranged through the two fixed plates, a nut for pressing the fixed plate is arranged on the end of the bolt, and the broken knife is rotationally connected with the bolt on the corresponding fixed knife seat. A through hole through which the bolt passes is formed in the broken knife, and the broken knife is rotationally connected with the bolt through the through hole. The broken knife is designed in a movable manner.

[0008] As a further improvement of the utility model, the fixed plate is trapezoidal, and the limiting plate is fixed to the side of the two fixed plates close to the push head. The limiting plate limits the broken knife to prevent the broken knife from continuing to rotate towards the feeding port.

[0009] As a further improvement of the utility model, the lower part of the broken knife is inclined, the cutting part is a right-angled triangle, each cutting part is sequentially arranged from top to bottom, and the side of the broken knife away from the push head is provided with a triangular protruding part. The cutting part is used to cut open the garbage bag.

[0010] As a further improvement of the utility model, the cross section of the mounting beam is U-shaped, and the mounting beam is fixedly connected with the fixed beam on the box. A plurality of mounting grooves are formed in the front and rear sides of the mounting beam, and the fastener is fixedly connected with the fixed beam through the mounting groove.
