Problems solved by technology

[0010] Second, the "broken mechanism" is unreasonable
Shaping requires the crushing mechanism of "selective crushing", which is not available in existing jaw crushers

Embodiment 1

[0079] Embodiment 1: as figure 1 As shown, a stepped crushing cavity with a negative bite angle includes two jaw plates 1, one of which has a four-fold broken line structure. The two jaw plates 1 face each other to form a stepped crushing chamber; the two jaw plates 1 face each other to form a stepped crushing chamber Cavity 2, the stepped crushing chamber 2 formed by the confrontation of the working faces of the two jaw plates 1 gradually becomes smaller in size from top to bottom, and the shape of each crushing chamber is a structure with a small upper part and a larger lower part; The direction of the included angle formed by the working surface of the jaw plate 1 is downward.

[0080] The tooth profile structure on the working surface of the two jaw plates 1 gradually decreases from top to bottom, that is, the tooth height gradually decreases, the tooth width gradually narrows, and the tooth spacing gradually decreases.

[0081] In the stepped crushing chamber 2, the work...

Embodiment 2

[0083] Embodiment 2: as figure 2 As shown, in the stepped crushing chamber 2, the two jaw plates 1 working faces of the last crushing chamber at the lower end have a narrow and long structure. The angle range of the working face angle is ~+1 degree;

[0084] The working surfaces of the two jaws forming the long and narrow structure are all planar light plate structures.

[0085] The shape of each stage crushing chamber in the stepped crushing chamber 2 is left-right symmetrical. The two jaw plates of the stepped crushing chamber 2 are respectively integrally die-cast.

[0086] All the other are with embodiment 1.

Embodiment 3

[0087] Example 3: In the stepped crushing cavity 2, the two jaws 1 working surfaces of the last crushing cavity at the lower end have a narrow and long structure. 1 The angle range of the working surface angle is -8 degrees.

[0088] The stepped crushing chamber 2 has a two-stage stepped structure. The shape of each stage crushing chamber in the stepped crushing chamber 2 is left-right asymmetric structure.

[0089] All the other are with embodiment 1.

Abstract

The invention discloses a negative-occlusion angle step type crushing cavity which comprises two jaw plates, wherein at least one of the two jaw plates is of an over-twice-broken line structure; the two jaw plates are oppositely arranged to form a step type crushing cavity; the size of the step crushing cavity formed by the opposite working surfaces of the two jaw plates is gradually reduced step by step from top to bottom; the shape of each level of crushing cavity is of a trapezoidal structure with a small top and a large bottom; an angle formed by the working surfaces of the two jaw plates forming the two waists of the trapezoidal-structure crushing cavity faces downward. Through the technical measures of 'grading, translation and negative angle', the crushing cavity of the prior art is improved to a structure with a shaping function, which is the core technology of the invention. The limitation that the crushing cavity of the prior art is suitable for crushing only but not suitable for shaping is broken through, and the function range of a jaw crusher is remarkably expanded.

Description

technical field [0001] The invention relates to the technical field of crushing equipment, in particular to a stepped crushing chamber with a negative bite angle. Background technique [0002] Jaw crusher, also known as jaw crusher, has a long history. In the "big family" of crushers, jaw crushers have become one of the most widely used crushing equipment due to their simple structure, low cost, low power consumption and easy maintenance. [0003] Jaw crusher is a typical "coarse crushing" equipment. [0004] Crude here has two meanings: [0005] 1. The material crushed by the jaw crusher is very coarse, that is, it is very difficult for the jaw crusher to crush fine materials (this is related to the structure of the crushing cavity of the jaw crusher), and it is usually difficult to crush to a particle size below 30mm. [0006] 2. The crushed material of the jaw crusher is the primary product (the particle shape of the product is needle or flake, which is very serious, a...
