Embodiment Construction

[0017] Such as Figure 1 to Figure 4 As shown, a modular impact crusher includes a base 1, a rotor part 2 is installed on the base 1, and a front frame 4 and a rear frame 10 are detachably installed on the base on both sides of the rotor part 2 through bolts. Both the frame 4 and the rear frame 10 adopt square steel as the frame structure foundation and are welded into shells. The openings of the front frame 4 and the rear frame 10 are arranged oppositely. The preferred rear frame is in the shape of a right-angled trapezoid. The side away from the front frame side is the short side of a right-angled trapezoid. The front frame 4 is located on the front side of the rotor component, that is, the direction of the material inlet. A front inspection door 3 is connected between the front frame 4 and the rear frame 10. The front inspection door 3. A front liner 14 is provided on the inner side. The front inspection door 3 is symmetrically hinged on both side frames of the rear frame. ...

Abstract

The invention relates to the field of crusher devices, in particular to a modular impact crusher convenient to maintain. The modular impact crusher comprises a base, a rotor part is arranged on the base, a front frame and a rear frame are arranged on the two sides of the rotor part, a front inspection door is arranged between the front frame and the rear frame, rear inspection doors are arranged on the two side faces of the rear frame respectively, an upper inspection door is arranged between the tops of the front frame and the rear frame, and a lower inspection door is arranged on the side face, away from the front frame, of the rear frame. At least two hinge shaft bases I are arranged on a transverse beam I of the front frame, the front end of an upper impact rack is arranged in the hinge shaft bases I, an upper adjusting device is arranged in a U-shaped groove of an upper transverse beam of the rear frame, the front end of a lower impact rack is arranged in hinge shaft bases II, anda lower adjusting device is arranged in a U-shaped groove of a lower transverse beam. Each hinge shaft base comprises a fixing hinge shaft base body and a press cover which are in butted connection up and down. According to the modular impact crusher, a damaged lateral lining plate and a damaged flat hammer can be replaced on the outer side of a cabin, the maintenance way of the impact crusher ischanged, and the maintenance difficulty is reduced.

Description

technical field [0001] The invention relates to the field of crusher equipment, in particular to a modular impact crusher that is easy to maintain. Background technique [0002] As a crusher that uses the impact principle to crush materials, the impact crusher has the characteristics of simple structure, high reliability, and wide application range, and is widely used in mining, chemical, construction, railway and other industries. [0003] There are wear-resistant parts installed inside the impact crusher, including the liner on the frame, the impact liner on the impact frame, and the blow bar on the rotor. The impact wear is very serious during operation and needs to be replaced frequently. The traditional maintenance method of the impact crusher is to separate the upper frame and the lower frame at a certain angle through the hinge device, and the staff enters the inside of the machine and takes out the side liner, impact frame, blow bar, etc. that need to be replaced. D...
