When crushing, if the adjusting hydraulic cylinder (16) of the automatic set adjustment mechanism (17) is adjusted to the set pressure for the place where the object to be crushed is normally crushed, pressure fluctuations within the set pressure range can be avoided. , hydraulic actuator (20
) moves and the cylinder rod (18) of the rod (18
) and the sleeve (19), the opening of the crushed material outlet (15) is maintained in a stable state, and a load exceeding the set pressure is applied to the trouble plate (12). In this case, pressure oil flows into the inner surface of the sleeve (19), expanding the sleeve (19) in the circumferential direction, removing interference between the sleeve (19) and the rod (18), and allowing the rod (18) to move freely with minimal resistance. back up to the stroke of
The swing jaw (3) retreats relative to the fixed teeth (6) in accordance with the amount of retreat, and the gap between the fixed teeth (6) and the movable teeth (2) expands, allowing foreign matter that is difficult to crush to flow into the crushed material outlet (15). ),
The abnormal load is reduced, and if the pressure is automatically removed through the unlock boat (25) of the hydraulic actuator (20) at the same time as the foreign object passes, the rod (18) returns to its original position and regains its holding function and swings at the same time. Joe (
3) returns to its original position, so toggle plate (12
) breakage and damage to the crusher body (1) can be prevented, and since the abnormal load applied to the hydraulic actuator (20) is only in the axial direction, the movement of the cylinder rod (18) is performed smoothly, and the hydraulic actuator This can prevent damage to itself.

(Effects) The present invention, which has the configuration and operation as described above, adjusts the set pressure range applied to the swing jaw during crushing by an automatic cellar Y adjustment WJ mechanism using a hydraulic cylinder, and comprises a hydraulic actuator interlocked with the hydraulic cylinder. The safety device locks the movement of the cylinder rod of the actuator in any position using the sleeve and frictional force in response to the pressure within the set pressure range, so the swing jaw is maintained in a stable state and prevents abnormal loads caused by foreign objects that are difficult to crush. When this occurs and the swing jaw receives this pressure, the lock between the cylinder rod and sleeve is released and the rod V
Since the shredded material discharge port is expanded by retreating, this has excellent effects such as preventing breakage of the toggle plate and damage to the crusher main body, automatic set adjustment mechanism, and safety device.

If a foreign object that is difficult to crush is caught between the movable tooth (32) and the fixed tooth (37) and a load exceeding the pressure set in (45) is applied, the sleeve (20) of the hydraulic actuator (20) Pressure oil flows into the inner surface of the sleeve (19), expands the sleeve (19) in the circumferential direction, releases the interference between the sleeve (19) and the rod (18), and causes the rod (18) to expand.
) retreats to the desired stroke with minimum resistance, and the swing jaw (34) moves away from the fixed tooth (37) according to the amount of retreat, and the gap between the moving tooth (32) and the fixed tooth (37) expands and fractures. Difficult foreign objects will pass through the crushed material outlet (5G) and the abnormal load will be removed.If the pressure is automatically removed through the unlock board (25) of the hydraulic actuator (2O) at the same time as the foreign object passes, the rod (18 ) returns to its original position and restores its holding function, while at the same time swinging jaw (
34) will return to its original position, so there will be no trouble)
(45) and damage to the crusher body (31) can be prevented, and since the abnormal load on the hydraulic actuator (26) is only in the axial direction, the cylinder rod (18) can be moved smoothly. This can prevent damage to the actuator (26) itself, and the crusher according to the embodiment
A) is crushing 1! This has the same effect as (A).

A swing jaw having movable teeth on the front surface is swingably mounted, fixed teeth are provided on the front wall of the crusher main body in correspondence with the movable teeth, and a swing jaw is swingably mounted on the lower rear surface of the swing jaw. Through the toggle plate installed between the toggle blocks, the frictional force between the cylinder rod and the sleeve built into the cylinder of the block is connected to a hydraulic actuator operated by pressure changes from a separate hydraulic cylinder for adjustment, which crushes the toggle blocks. The exit opening of the machine is automatically set, and when a load exceeding the set frictional force is applied, the frictional force is automatically released and the rod is retracted to the desired stroke to expand the exit opening. A crusher with a safety device that has an automatic set adjustment mechanism.
