Description

Crushing toothed plate with material guiding function Technical Field The utility model relates to a crushing toothed plate, in particular to a crushing toothed plate with a material guiding function. Background When ore is crushed, the jaw crusher is an indispensable device in coarse crushing, and the jaw crusher utilizes the crushing toothed plate to tear, extrude and other operations on massive materials, so that the materials are crushed into smaller particles, and the requirement of a production process on the granularity of the materials is met. At present, crushing pinion rack on the market all adopts equidistant strip sand grip that sets up to realize crushing, and patent as application number CN201420527905.X discloses a jaw breaker pinion rack, including the pinion rack body, the pinion rack body upper surface sets up the crushing tooth of arranging evenly, and in addition, most racks are linear type tooth and equidistant setting. The equidistant rack that sets up does not possess the guide and realizes the broken function of segmentation in the course of the work, just sets up for the booth at the rack of feed end promptly, and big material will be broken by a plurality of racks at the feed end, can make the load of breaker too big, also can appear simultaneously big material for a long time at being located the feed end, influences broken efficiency. Disclosure of utility model Based on the defects in the prior art, the utility model provides the crushing toothed plate with the material guiding function. The technical scheme adopted for solving the technical problems is as follows: Broken pinion rack with guide function, including the pinion rack body, be equipped with the rack on the pinion rack body, the pinion rack has feed end and discharge end, and the pinion rack body is isosceles trapezoid and its feed end is wider than the discharge end, and its middle part is equipped with the benchmark rack that extends along length direction, and the benchmark rack both sides outwards are equipped with symmetrical slope rack, and the interval of adjacent rack discharge end department is the same and the interval of feed end department increases to both sides ladder from the middle part. Preferably, the toothed plate body is provided with an inclined first guide surface at the feed end. Preferably, the feed end of each rack is provided with a first chamfer for guiding. Preferably, the discharge end of the toothed plate body has an inclined second guide surface. Preferably, the discharge end of each rack is provided with a second chamfer for guiding. Compared with the prior art, the toothed plate has the advantages that the toothed plate body is of a trapezoid structure, the racks are of a gap gradual change structure, so that after materials enter, the large materials are slightly extruded at the top to enable the edge parts of the large materials to be crushed and the size to be small, the large materials gradually move downwards after the size is small, the downward extrusion amplitude is gradually increased in the downward process, the crushing of the materials is facilitated, the load of equipment is reduced, and in addition, guide surfaces are arranged at the two ends for guiding the materials, so that the feeding and the discharging of the materials are facilitated.
