Embodiment Construction

[0046] The technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings.

[0047] Such as figure 1 with figure 2The crusher of the shown embodiment includes: a static jaw 1 arranged on a fixed frame 7, a movable jaw 2 arranged above the static jaw 1 through a movable bracket 8 installed on the fixed frame 7 via an eccentric shaft 3 , and a driving device for driving the eccentric shafts 3 to rotate synchronously. The static jaw 1 is inclined downward from the entrance to the exit. The movable jaw 2 is arranged opposite to the static jaw 1, and gradually approaches the static jaw 1 from the entrance to the exit; the eccentric shafts 3 are set to six, and each of the eccentric shafts 3 is arranged along the direction of the movable jaw 2. The horizontal swing direction of is set at the same interval. The eccentric shaft 3 is composed of a straight shaft body and five circular eccentric wheels fixed...

Abstract

The invention provides a crushing machine. The crushing machine comprises static jaws and moving jaws, wherein the static jaws are oppositely fixed and arranged in a downwards inclined manner from an inlet to the back, the moving jaws are installed above the static jaws through eccentric shafts which are fixed relative to the static jaws, and the moving jaws are opposite to the static jaws and are arranged in a basically horizontal manner; and more than two eccentric shafts are arranged, all the eccentric shafts are arranged at intervals in the horizontal swing direction of the moving jaws, and all the eccentric shafts have the same eccentric direction and eccentric distance. The crushing machine further comprises a driving device used for driving all the eccentric shafts to synchronously rotate, and the moving jaws are driven by the eccentric shafts to move in a reciprocating manner. Due to the fact that more than two eccentric shafts are utilized for driving the moving jaws, acting force on the moving jaws is dispersed to the eccentric shafts, and then acting force borne by each eccentric shaft is greatly reduced; and therefore, the diameter of the eccentric shafts can be decreased, and the size of the crushing machine can be decreased. Due to the fact that the acting force borne by the eccentric shafts can be reduced, the eccentric shafts are not prone to be damaged, and the service life of the crushing machine is prolonged.

Description

technical field [0001] The invention relates to the technical field of crushing, in particular to a crusher. Background technique [0002] Jaw Crusher is a crushing cavity composed of a movable jaw and a static jaw, which simulates the movement of the two jaws of animals to complete the material crushing operation. Crushing of ores and bulk materials. [0003] Existing jaw crushers usually include one or more movable jaws, each movable jaw is separately sleeved on an eccentric shaft, and each eccentric shaft is also driven by a motor, and each eccentric shaft drives the corresponding movable jaw to do cycle Sexual reciprocation. For example, Chinese patent document CN101829612 discloses a jaw vibrating crusher, which includes a movable jaw with a sloped top surface and an eccentric vibrating device (ie, an eccentric shaft) installed on the movable jaw, and the rotating shaft of the eccentric vibrating device and the drive The output shaft of the motor is connected with a ...
