Abstract

The invention discloses an adjusting device of a counterattack rack and a crashing machine, relates to the technical field of engineering machinery, and solves the technical problems that the function is single and the usage is inconvenient in the prior art. The adjusting device of the counterattack rack comprises a connecting rod, a spring, a positioning plate and an oil cylinder, wherein the oil cylinder comprises a cylinder barrel and a piston rod with two ends extending out of the cylinder barrel; a first oil port and a second oil port are formed in the cylinder barrel; the connecting rod is sleeved with both the piston rod and the spring; both the piston rod and the spring can slide relative to the connecting rod; a mounting hole is formed in the positioning plate; the cylinder barrel is fixedly connected with the positioning plate; both the piston rod and the connecting rod penetrate through the mounting hole in the positioning plate; an adjustment piece can be detachably and fixedly connected to one end, deviated from the spring, of the connecting rod; and the adjustment piece abuts against the piston rod of the oil cylinder. The crashing machine comprises the adjusting device of the counterattack rack. The adjusting device of the counterattack rack and the crashing machine are used for improving the usage convenience of the adjusting device of the counterattack rack.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to an impact frame adjustment device and a crushing machine provided with the impact frame adjustment device. Background technique [0002] The impact crusher is a crushing machine that uses impact energy to crush materials. [0003] The impact crusher mainly consists of figure 1 Shown counterattack frame adjustment device 90, counterattack frame 91, counterattack liner 92, rotor 93, blow bar 94, wear-resistant liner 95, shell 96, auxiliary opening device 97 and other components. When the machine is working, driven by the motor, the rotor 93 rotates at a high speed. When the material enters the action area of ​​the blow bar 94, it collides with the blow bar 94 on the rotor 93 and is crushed, and then is thrown to the impact liner 92 to be crushed again. It bounces back from the impact liner 92 to the action area of ​​the blow bar 94 for re-crushing, and this process ...
