Embodiment 1

[0031] refer to Figure 1-6 , this embodiment provides a crusher, including a bracket 2, a housing 1 fixed on the bracket 2, a crushing mechanism arranged inside the housing 1, and a driving device for driving the crushing mechanism to rotate; the housing 1 The upper part is provided with a feed inlet 7;

[0032] The crushing mechanism includes an extruding core 6 and a main shaft 301 eccentrically arranged on one side of the extruding core 6; the extruding core 6 is a Lelo triangle, and the other side of the extruding core 6 is provided with a groove, and an internal tooth 601 is arranged in the groove , the center of the end face of one side of the housing 1 is fixed with a gear 101 that cooperates with the internal teeth 601; the bottom of the housing 1 is provided with a through hole 102, and the shape of the side of the housing 1 is consistent with the running track of the tip of the extrusion core 6 and there is a gap; by adjusting The gap between the housing 1 and the ...

Embodiment 2

[0041] refer to Figure 7 The difference between the crusher of this embodiment and the first embodiment is that the side wall of the extrusion core 6 is provided with piercing teeth 602, and the inner wall of the housing 1 is provided with piercing teeth 602 with the same shape as the extrusion core 6. By adding The piercing teeth 602 effectively pierce the crushed material during the process of reducing the space formed by the edge of the extrusion core 6 and the shell 1, further enhancing the crushing effect of the crusher.

[0042] By adjusting the gap between the housing 1 and the extrusion core 6, crushed objects with different target particle sizes can be realized, so that the crusher can be used in a wider range.

[0043] During the rotation of the extrusion core 6, the gap between the extrusion core 6 and the inner wall of the casing 1 will change from large to small, so as to achieve the purpose of crushing.

[0044] A gap is reserved between the casing 1 and the ex...

Abstract

The invention relates to the field of engineering equipment, in particular to a crusher. The crusher comprises a support, a shell fixed to the support and a crushing mechanism arranged in the shell. The crushing mechanism comprises an extrusion core and a main shaft eccentrically arranged on one side of the extrusion core. The extrusion core is in the shape of a Reuleaux triangle, a groove is formed in the other side of the extrusion core, inner teeth are arranged in the groove, and a gear matched with the inner teeth is fixed to the center of an end face of one side of the shell. A through hole is formed in the bottom of the shell, the shape of the side face of the shell is consistent with the moving track of the tip of the extrusion core, and a gap exists between the side face of the shell and the moving track of the tip of the extrusion core. The diameter of the gear is smaller than that of the groove. The main shaft is superposed to the axis of the gear. According to the crusher, three-time extrusion crushing can be achieved when the extrusion core rotates by a circle, and the crushing efficiency is greatly improved.

Description

technical field [0001] The invention relates to the field of engineering equipment, in particular to a crusher. Background technique [0002] With the development of society, urban buildings are being updated day by day. In the construction process, sand and gravel raw materials are used in a large amount and a large amount of raw material supply is required. In terms of stone, crushers are used especially frequently. Crusher is the core equipment used to produce sand and gravel. It is used to crush large pieces of material into materials with a predetermined particle size. According to the crushing operation and the size of the discharge particle size, it is divided into coarse crushing, medium crushing and fine crushing. Commonly used gravel equipment includes jaw crusher, impact crusher, impact crusher, compound crusher, single-stage hammer crusher, vertical crusher, gyratory crusher, cone crusher, and roll crusher. Crusher, double roll crusher, two-in-one crusher, one-t...
