Embodiment Construction

[0058] In the following description, like reference numerals denote like elements. It should be noted that the drawings are not in all cases drawn to scale and that they are mainly for the purpose of illustrating embodiments of the invention.

[0059] figure 1Shown is a jaw crusher 100 comprising: a fixed jaw 101 as the front part of the jaw crusher; Type crusher frame side plate 103 support. The rear part 108 of the frame of the jaw crusher is fastened between these side plates. The pendulum is supported by the rear of the frame through toggle plate 104 . Furthermore, a tie rod 105 is arranged between the lower end of the pendulum and the rear part 108 of the frame; the tie rod is loaded by a spring 107 . When the spring 107 is locked, the pull rod pulls the pendulum 102 back against the toggle plate 104 . With the locking device 110 according to a preferred embodiment of the present invention, the spring acting on the pull rod is mounted in place. The jaw crusher inclu...

Abstract

A method for compressing or decompressing a spring (107) loading a tie rod (105) in a jaw crusher (100), which tie rod is supported by, at one location, a pendulum (102) of the jaw crusher and, at another location, the jaw crusher's frame (108) through the said spring; and the spring is installed between the jaw crusher's frame and a second spring support (112) supported by the tie rod; and the second spring support is moved in relation to the tie rod. A support part (113) of the tightening device (110) and at least two moving screws (114-114'''') supported by the support part are arranged to influence the second spring support (112); the support part is supported by the tie rod (105) through a locking member (120); and the at least two moving screws supported by the support part are moved to change the distance between the second spring support and the support part. The invention further provides a tightening device (110), a jaw crusher (100), and processing plant of mineral material (200).

Description

technical field [0001] The invention relates to the locking of the springs that load the tie rods in jaw crushers for mineral materials. Background technique [0002] Mineral material, such as rock, for crushing may be obtained from the ground by blasting or excavation. This rock can also be natural stone and gravel, or construction waste. Crushing is carried out using non-stationary crushers and stationary crushing equipment. The material to be crushed is fed by means of an excavator or wheel loader into the hopper of the crusher or crushing plant, from which the material to be crushed can fall into the throat of the crusher, or by a feeder Transfer rock material to crusher. The mineral material to be crushed can also be a recyclable material such as concrete, brick or asphalt. [0003] Jaw crushers are suitable, for example, for rough crushing in quarries or for crushing construction materials. According to the working principle of the jaw crusher, crushing is carried...
