Embodiment 1

[0031] Such as Figure 4 As shown, the height of the horizontal plane at the bottom of the movable jaw plate mounting body 9 is higher than that of the bottom end of the crushing frame 3, and there are gaps between the front and rear side walls of the movable jaw plate mounting body 9 and the front and rear inner walls of the crushing frame 3, the first installation There are two groups of screw holes 10 and they are arranged below the middle part of the right side wall of the movable jaw plate mounting body 9. There are two groups of toggle plates 13 and they are arranged symmetrically with the center of the side of the adjuster 14 as the center of symmetry; the height of the first installation groove 15 is equal to that of the movable jaw plate. The height of the jaw plate installation body 9, the movable jaw plate 17 is an inclined plate, the height of the second installation groove 21 is equal to the height of the first installation groove 5, the fixed jaw plate 23 is also ...

Embodiment 2

[0035] On the basis of Embodiment 1, the length of the first mounting screw 19 is greater than the maximum horizontal distance from the through hole 28 to the first through screw hole 18, the first mounting screw 19 is composed of a threaded part and a smooth part, and the length of the threaded part is longer than the first The sum of the lengths of the through screw hole 18 and the first mounting screw hole 10, the length of the second mounting screw 27 is greater than the maximum vertical distance between the second mounting screw hole 24 and the second through screw hole 26, which is convenient for the first mounting screw 19 And the installation of the second mounting screw 27.

Abstract

The invention relates to the field of ore crushing, in particular to a jaw crusher for ore crushing. The fixed jaw plate and the movable jaw plate are installed on the fixed jaw plate installation body and the movable jaw plate installation body through threaded connection. The plate passes through the second installation screw hole, the screw hole and the second through screw hole through the second installation screw thread, and the fixed jaw plate is fixed on the fixed jaw plate installation body, which is convenient for the installation, replacement and maintenance of the fixed jaw plate; the movable jaw plate Through the first installation screw thread through the first installation screw hole and the first through screw hole, the movable jaw plate is fixed on the movable jaw plate installation body, which is convenient for installation, replacement and maintenance of the movable jaw plate; When the ore is crushed, it will cause damage to the inner wall of the crushing frame, and the protective plate is fixed on the inner wall of the crushing frame through the fixed screw threaded connection of the fixed screw hole and the matching screw hole thread, which is convenient for installation, disassembly and replacement.

Description

technical field [0001] The invention relates to the field of ore crushing, in particular to a jaw crusher for ore crushing. Background technique [0002] The jaw crusher is commonly known as the jaw crusher, also known as the tiger's mouth. It consists of two jaw plates, the movable jaw and the static jaw. Crushing of various ores and bulk materials in road, railway, water conservancy and chemical industries. The working part of the jaw crusher is two jaw plates, one is the fixed jaw plate (fixed jaw), which is fixed vertically (or the upper end is slightly outward) on the front wall of the machine body, and the other is the movable jaw plate (moving jaw). Inclined, forming a crushing cavity (working cavity) with a large top and a small bottom with the fixed jaw plate. The movable jaw plate makes periodic reciprocating motions against the fixed jaw plate, sometimes separating and sometimes approaching. When separated, the material enters the crushing cavity, and the finis...
