Embodiment 1

[0032] Such as Figure 1 to Figure 4As shown, according to this embodiment, the gap adjustment mechanism at the discharge port of the crusher is arranged between the movable jaw assembly 30 and the frame 20, and by adjusting the distance between the movable jaw assembly 30 and the frame 20, the movable jaw assembly 30 and the frame 20 are realized. Adjustment of the gap between the discharge ports 41 between the static jaw assemblies 10. The discharge opening gap adjustment mechanism in this embodiment includes a first wedge block 60 and a second wedge block 70 as a wedge mechanism, and an adjustment screw 81 and an adjustment nut 82 as an adjustment device 80 . The angle between the normal line of the wedge surface in the first wedge 60 and the second wedge 70 and the adjustment direction is smaller than the self-locking angle of the wedge, and the adjustment screw 81 and the adjustment nut 82 drive the first wedge 60 and the second The part where the wedge-shaped surface in...

Embodiment 2

[0040] The difference between the gap adjustment mechanism at the discharge port of the crusher in this embodiment and Embodiment 1 is that the adjustment mechanism is arranged between the static jaw assembly 10 and the frame, and its specific structure can be found in Embodiment 1, so it will not be repeated here. It can also be realized that the adjustment device in the gap adjustment mechanism does not need to occupy space in the adjustment direction of the gap adjustment mechanism, for example, does not need to occupy space at both ends of the wedge mechanism, thus ensuring the compact structure of the entire adjustment mechanism.

[0041] It can be understood that the adjustment mechanism is arranged between the static jaw assembly 10 and the frame, and is also arranged between the movable jaw assembly and the frame, which can also achieve the purpose of the present invention.

Embodiment 3

[0043] The difference between the gap adjustment mechanism at the discharge port of the crusher in this embodiment and Embodiment 1 is that the adjustment device is a hydraulic telescopic cylinder 90 arranged in the accommodation cavity in the first wedge block and the second wedge block, and the hydraulic telescopic cylinder 90 The two ends of the two sides are respectively connected to the first wedge block and the second wedge block, so that when the first wedge block and the second wedge block are driven to realize the adjustment of the outlet gap, the hydraulic telescopic cylinder 90 can be combined with the hydraulic device, Realize the automation of the gap adjustment of the gap adjustment mechanism of the discharge port of the crusher.

[0044] see further Figure 5 and Figure 6 , in this embodiment, the gap adjustment mechanism at the discharge port of the crusher also includes a limit mechanism arranged on the first wedge block 60 and the second wedge block 70, and...

Abstract

The invention provides a breaker discharging opening gap adjusting mechanism and a jaw type breaker. The adjusting mechanism is arranged between a movable jaw assembly and a rack and/or between a fixed jaw assembly and the rack and comprises a wedge mechanism and an adjusting device; the included angle between the normal of the wedge face of the wedge mechanism and the adjusting direction is smaller than the self-locking angle of the wedge face; the adjusting device drives a component wherein the wedge face in the wedge mechanism is located to move in the direction, wherein the included angle between the adjusting direction and the direction is larger than that of the normal of the wedge face, and the included angle between the direction and the normal is larger than the self-locking angle; the wedge face drives a component adjacent to the component where the wedge face is located to generate motion parallel to the component in the adjusting direction; the adjusting device is at least partly located in the wedge mechanism; the adjusting device is at least partly located in the wedge mechanism, the adjusting device in the gap adjusting mechanism does not occupy space in the adjusting direction of the gap adjusting mechanism, for example, the adjusting device does not need to occupy the spaces in the two ends of the wedge mechanism, and structural compactness of the whole adjusting mechanism is ensured.

Description

technical field [0001] The invention relates to the technical field of crushers, in particular to a gap adjustment mechanism at a discharge port of a crusher and a jaw crusher. Background technique [0002] The jaw crusher is mainly composed of two jaw plates, the movable jaw and the static jaw, to simulate the movement of the two jaws of animals to complete the material crushing operation, so it is widely used in mining, smelting, building materials, roads, railways, water conservancy and chemical industry, etc. Medium-sized crushing of various ores and bulk materials in the industry. For example, Chinese patent document CN204583288U discloses a compound pendulum jaw crusher, including a frame, and a drive unit and a movable jaw set arranged on the frame. The fixed jaw frame, between the movable jaw group and the fixed jaw frame is the crushing cavity, and the bottom of the crushing cavity is provided with a discharge port. [0003] At present, after the jaw crusher has b...
