[0002] Jaw crusher is widely used in mining, smelting, building materials, highway, railway, water conservancy and chemical industries for medium-sized crushing of various ores and bulk materials. It is composed of two jaw plates, movable jaw and static jaw, to form a crushing chamber, and simulates the movement of two jaws of animals to complete the material crushing operation. At present, the tooth plates are the most seriously worn in the crusher, especially the middle part, which wears particularly fast. Moreover, the current tooth plates are all in one piece. After serious wear, the whole piece needs to be replaced, which is quite wasteful. Therefore, based on the existing equipment, the tooth plates are modified and manufactured in blocks. After a part is worn, they can be quickly replaced to adapt to the current production environment. Utility Model Content

DETAILED DESCRIPTION

[0018] The present invention will be described below based on the embodiments in conjunction with the accompanying drawings in the embodiments of the present invention. However, it is worth noting that the present invention is not limited to these embodiments. In the detailed description of the present invention below, some specific details are described in detail. However, for the parts that are not described in detail, those skilled in the art can also fully understand the present invention.

[0019] In addition, those skilled in the art should understand that the drawings are only provided to illustrate the purpose, features and advantages of the present invention, and the drawings are not actually drawn according to scale.

[0020] At the same time, unless the context clearly requires otherwise, the words "include", "comprises" and similar words throughout the specification and claims should be interpreted as inclusive rather than exclusive or exhaustive; that is, the meaning is "including but not limited to".

[0021] See also Figure 1-Figure 7 The utility model provides a technical solution: it includes a base 1, wall panels 2 are arranged on both sides above the base 1, a fixed seat 3 is arranged in front of the wall panel 2, a movable jaw 5 and an adjustment seat 10 are arranged between the wall panels 2 on both sides, a rotating shaft is arranged at the upper end of the movable jaw 5, and a pulley 4 is arranged at the end of the rotating shaft, a tooth plate 6 is arranged behind the fixed seat 3 and in front of the movable jaw 5, and a variable diameter long strip hole 9 is arranged on the fixed seat 3 and the movable jaw 5, the tooth plate 6 includes a slat 601 and a limiting nail 602, an extrusion block 7 is arranged above the slat 601, and a toggle plate 11 and a spring pull rod 12 are arranged between the lower end of the movable jaw 5 and the adjustment seat 10.

[0022] The tooth plate 6 is composed of a plurality of slats 601, and a tooth groove is provided in front of the slats 601. The limiting nail 602 is fixedly connected to the rear of the slats 601. The limiting nail 602 can be inserted into the long strip hole 9. The extrusion block 7 can be interconnected with the fixed seat 3 and the movable jaw 5 by bolts.

[0023] Threaded holes 603 are provided at both ends of the slat 601, and the threaded holes 603 can be connected to hanging rings. Inclined surfaces are provided at both ends of the slat 601, and the cross section of the extrusion block 7 is a trapezoid.

[0024] The rotating shaft of the movable jaw 5 is an eccentric shaft, and both ends of the rotating shaft are arranged on the wall panel 2 through bearing seats, and a flywheel 8 is arranged at the other end of the rotating shaft.

[0025] A reinforcing strip 13 is also attached to the top of the extrusion block 7 , and the reinforcing strip 13 is also fixed to the fixing seat 3 and the movable jaw 5 by bolts.

[0026] When using the utility model, the technician sets the tooth plate 6 into multiple slats 601, which are symmetrically arranged up and down. There are limit pins 602 distributed at the rear of the slats 601. The limit pins 602 are inserted into the variable diameter strip holes 9 for limiting. After being inserted, they are slid and limited. Then, the extrusion blocks 7 are used for final fixation. One extrusion block 7 corresponds to one slat 601, which is convenient for maintenance and extrusion fixation. The designed inclined surface is more stable.
