Although the crushing machine has various types, there are methods of crushing materials such as extrusion, bending, impact, shearing, and grinding, depending on the method of application of force. In a crushing machine, the force application condition is complex, several kinds of force application often exist at the same time, and only one or two kinds of main force application exist in a certain crushing machine. Because the shape of the material particles is irregular and the physical properties of the material are different, the adopted crushing method is different, and the crushing method mainly comprises the following steps: the method is generally suitable for crushing large materials and splitting: between a plane and a working plane with sharp edge, when the working plane with sharp edge extrudes the material, the material will be split along the direction of the pressure action line, the splitting is caused because the tensile stress on the splitting plane reaches or exceeds the limit of the tensile strength of the material. The tensile strength limit of the material is much smaller than the compressive strength limit, and the material is broken: the material is crushed by the left and right bending stress, and when the bending stress of the crushed material reaches the bending strength of the material, the crushed material is broken and crushed. However, when the steel scrap material is treated, some materials with high hardness and bending strength may exist in the steel scrap material, and may not be screened out, when the materials with high hardness and bending strength are put into the crusher, the cutter head in the crusher may be damaged due to the fact that the ordinary crusher does not have the automatic stopping function, and the whole equipment may be seriously damaged, so that the cost of a user is increased, the maintenance is inconvenient, and the production efficiency is reduced, at present, some equipment has the automatic stopping function, when the materials with high hardness and bending strength are encountered, the crusher may automatically stop working to avoid the damage to the equipment, but when the equipment is stopped, the materials are already blocked in the crushing cutter head group, the roller cannot rotate, a large amount of manpower is required to take out the materials blocked in the equipment, although the equipment is protected, but still requires a lot of manpower to maintain, reducing production efficiency. The device can solve the existing problems, the materials to be crushed are put into the case 1, the stop block 11 fixed on the piston rod of the telescopic cylinder 10 is positioned at one side of the slide block 3 close to the inner wall of the case 1 to prevent the slide block 3 from moving towards the inner wall of the case 1, and the baffle 8 on the guide rod 6 is clung to the side wall of the case 1 to effectively prevent the two crushing rollers from colliding with the knife, the stop block 11 and the baffle 8 can fix the two rollers during normal operation, so that the normal operation of the equipment cannot be influenced, the stability is high, when the materials with higher hardness and large bending strength are put between the two crushing rollers in the case, the current can be increased because the gap between the two crushing rollers can not be changed, when the current is increased to a certain value, the control system can send out electric signals to the telescopic cylinder motor, and the telescopic cylinder motor starts to work, the telescopic cylinder 10 is contracted to drive the stop dog 11 fixed on the piston rod of the telescopic cylinder 10 to move downwards, the slide block 3 is not blocked by the stop dog 11 and can move freely, the distance between the two crushing rollers is changed, meanwhile, the crushing rollers continue to rotate to drive the material between the two crushing rollers to be discharged, the material is prevented from being clamped between the two crushing rollers, thereby not only protecting equipment, but also saving a large amount of manpower and increasing the production efficiency, when the harder and high-bending-strength material is rotated away by the crushing rollers, the two crushing rollers can approach each other due to the action of the spring, the reduced gap can ensure that the material can continue to be crushed, the production efficiency cannot be influenced, at the moment, only the conveying equipment needs to be paused, the two crushing rollers recover to the original positions after the material in the crusher is crushed, and the control system sends an electric signal to the telescopic cylinder 10, the original position of the stop block 11 is recovered when the crushing device works, so that the crushing device can be ensured to continue to work normally.
