Abstract

The utility model relates to a jaw plate for a jaw crusher which is mainly characterized in that the working surface of the jaw plate has a polygonal pyramid tooth structure so as to enhance the material crushing work efficiency and the rate of products meeting standards. Compared with a traditional strip shape tooth jaw plate crusher, the rate of products meeting standards in the utility model is raised by three times. The agate stone processing is taken as an example, and the material cost is reduced by 60%.

Description

Jaw crusher Hubei Province plate

The utility model belongs to machining equipment, is specifically related to the improvement of a kind of jaw crusher Hubei Province plate.

Main working parts Hubei Province plate of existing jaw crusher, by a fixed head with portable plate is supporting assembles, its fixed head and the portable plate working face of interlock mutually are corrugation shape shown in Figure 4, promptly be the alternate bar shaped flank of tooth of convex-concave, Hubei Province plate of this kind structure is applicable to the unsetting and undemanding material of granularity requirements of processing, but be not suitable for being used for processing granularity requirements strictness and the exigent valuable material of yield rate, as the processing of agate stone.

The purpose of this utility model is, by the improvement to Hubei Province plate occlusal working surface profile of tooth, provide a kind of suitable very strict to granularity requirements, and the very high valuable building stones of yield rate carries out jaw crusher Hubei Province plate of broken processing.

For achieving the above object, the utility model has adopted following technical scheme: Hubei Province plate is the two boards shape structure of split, promptly be divided into fixed head and portable plate, the plate face of two boards is slightly curved, a plurality of polygonal pyramid teeth are set on the arc face in an orderly manner, teeth are outwards most advanced and sophisticated, and are interlaced when the position distribution of teeth will be guaranteed interlock on the two plate faces, offer locating slot in the bottom of two plates.

Below in conjunction with accompanying drawing this is practically carried out comparatively detailed description.

Fig. 1 is the schematic perspective view of the utility model fixed head;

Fig. 2 is the AA profile of Fig. 1;

Fig. 3 is the BB profile of Fig. 1;

Fig. 4 is the schematic perspective view of the utility model portable plate;

Fig. 5 is the schematic diagram of prior art jaw crusher Hubei Province plate.

The utility model is made up of Fig. 1 and two plate-like body setted structures shown in Figure 4, on fixed head and portable plate arc face 2, polygonal pyramid shape teeth 1 are set respectively, teeth were staggered when the position distribution of teeth will be guaranteed two plate interlocks on the two boards, as embodiment of the present utility model, teeth are 4 pyramid types among Fig. 1 and Fig. 4,45 ° of taperings, tooth depth 13mm, plate face width 390mm, long 565mm, the teeth top is vertical, lateral separation is 50mm, in addition, and the two sides of fixed head, if fastening inclined-plane 3, offer locating slot 4 in its bottom, offer in the bottom of plate body 6 for the weight of lightened plate floor and alleviate groove 5, Fig. 4 illustrates portable plate bottom symmetry and offers two locating slots 7.

Effect of the present utility model and advantage: with fragmentation processing agate stone is example, one ton of agate stone raw material is processed into 12---the blank of 20mm granularity, utilize the utility model processing to need 8 hours, 600 kilograms of the qualified blanks of output, operating personnel need 3 people, as utilize traditional jaw crusher fragmentation to process, time is identical with the operator, qualified blank can only reach 150 kilograms, can find out that thus the utility model compares with existing equipment, and product percent of pass improves 4 times, compare as impacting fragmentation with the craft of generally adopting at present, effect of the present utility model also clearly, one ton of raw material of hand breaking need be operated one day with 20 people, the qualified blank of output has only 200 kilograms, can calculate thus, this is practical to be 7 times of man efficiency, and product percent of pass improved twice, analyzes processing cost from comprehensive economic index and can reduce by 60%.

Claims

1. jaw crusher Hubei Province plate, it is characterized in that the utility model has adopted split type two boards shape structure, be fixed head and portable plate, the plate face of two boards is slightly curved, a plurality of polygonal pyramid teeth are set on the arc face in an orderly manner, interlaced when the distribution of teeth position on the plate face will be guaranteed interlock.
