Example Embodiment

[0010] The present invention will be further described below in conjunction with the drawings.

[0011] Such as figure 1 , 2 As shown, the present invention discloses a limit device for a counterattack plate of a counterattack crusher, which includes a frame 1, a rotor 2, a counterattack plate 3, a hydraulic cylinder 4, a spring rod 5, and a limit device.

[0012] The limit device is composed of a safety hook 6 and a safety pin 7. The safety pins 7 are symmetrically arranged on both sides of the frame 1, and the safety hook 6 is symmetrically arranged on both ends of the counterattack plate 3.

[0013] The safety hook 6 of the limit device is provided with a hook head 6-1, the safety pin 7 is provided with a pin head 7-1, and the hook head 6-1 can be hooked on the pin head 7-1 in a matching manner.

[0014] The impact plate 3 controls the gap between it and the rotor 2 through the hydraulic cylinder 4 or the spring rod 5; when the hydraulic cylinder 4 drives the impact plate 3 to move,...

Abstract

The invention relates to an impact plate limiting device of an impact crusher. The impact crusher comprises a rack (1), a rotor (2), an impact plate (3), a hydraulic cylinder (4) and a spring pull rod (5), wherein the rotor, the impact plate, the hydraulic cylinder and the spring pull rod are arranged on the rack. The impact crusher is characterized in that the impact crusher additionally comprises a limiting device, the limiting device consists of safety hooks (6) and safety pins (7), the safety pins are symmetrically arranged on the two sides of the rack (1), the safety hooks are symmetrically arranged at the two ends of the impact plate, and the safety pins and the safety hooks are matched parts; and each safety hook of the limiting device is provided with a hook head (6-1), each safety pin is provided with a pin head (7-1) and the hook head (6-1) can hook the pin head (7-1) in a matched way. By adding the limiting device which consists of the safety pins on a shell and the safety hooks on the impact plate, the safe distance between the impact plate and the rotor is guaranteed, the equipment is protected and the safety production is realized.

Description

technical field [0001] The invention relates to a counterattack plate of an impact crusher, in particular to a limiting device for the counterattack plate of an impact crusher. Background technique [0002] The impact crusher is a crushing machine that uses impact energy to crush materials. After the large material enters the crushing chamber between the impact plate and the rotor, it obtains kinetic energy due to the rotation of the rotor part, repeatedly impacts between the impact plate and the rotor, and is crushed step by step through the crushing chamber and the uniform chamber respectively to achieve the required output. Material granularity. The function of the impact plate is to bear the impact of the material knocked out by the rotor, so that the material is crushed by the impact, and bounces the crushed material back to the impact area, and then performs impact crushing again to obtain the required product size. [0003] The counterattack plate of the existing im...
