detailed description

Below in conjunction with accompanying drawing, the utility model is further described.

As shown in Figure 1-3, a toothed roller crusher that can automatically adjust the clearance of the movable jaw plate includes a crushing motor, a pin shaft 1 installed on the crusher, and a rotating movable jaw plate mounted on the pin shaft 1 The two sides of the movable jaw plate are symmetrically provided with a tie rod device 3 that can rotate the movable jaw plate to increase the gap between it and the toothed roller of the crusher, and the pull rod device 3 is respectively installed at both ends of the pin shaft 1; 3. It is connected with a driving device that controls its movement. The driving device and the crushing motor are connected to the single-chip microcomputer. The single-chip microcomputer judges the size of the load through the fluctuation of the input current of the crushing motor, thereby outputting a control signal to the driving device.

The pull rod device 3 is composed of a pull rod 3-1, a slider 3-2 and a spring 3-4; the slider 3-2 is connected with the pull rod 3-1 by sliding fit, and one end of the pull rod 3-1 is provided with a pin hole 3 -3; the other end is connected with a spring 3-4 set on the rod body through a spring seat 3-5, and a lock nut 3-6 is threaded at the end; the slider 3-2 is connected to the block through the movable jaw plate 2. It is fixedly connected with the movable jaw plate, and the movable jaw plate connecting block 2 can move horizontally on the pull rod 3-1 of the pull rod device 3 with the slider 3-2, thereby driving the movable jaw plate to rotate and adjusting the gap between it and the crusher tooth roller. Clearance.

The pin hole on the pull rod 3-1 is in interference fit with the pin shaft 1, and the movable jaw plate is in clearance fit with the pin shaft 1.

The bottom surface of the slider 3-2 is provided with a chute along its length, and key grooves are symmetrically provided on both sides of the chute close to the end of the spring 3-4.
