Abstract

A crusher sieve plate consists of a front sieve plate and a rear sieve plate. The front sieve plate and the rear sieve plate are respectively arranged at two sides inside the crusher; a feed lifting rod is connected between the two sieve plates, wherein, a substrate of the front sieve plate is an arc plate with reticular sieve pores; locating safety seats of the feed lifting rod are evenly arranged on the arc surface near to the upper end of the arc plate; the safety seat passes through the arc sieve plate, the center of which is a fixing hole for the feed lifting rod; the rear sieve plate is a straight-plate with reticular sieve pores; the corresponding position to the front sieve plate at the upper end of the rear sieve plate substrate is also provided with corresponding locating safety seats and the fixing hole of the feed lifting rod. The crusher sieve plate can shorten the suspending length of the crusher feed lifting rod, improve the loading capacity of the feed lifting rod, greatly enhance the strength of the crusher sieve plate and prolong the service life of the equipment.

Description

The disintegrating machine sieve plate

One, technical field

The utility model relates to a kind of disintegrating machine sieve plate, belongs to mechanical equipment technical field.

Two, background technology

The disintegrating machine sieve plate is the vitals in this whole set equipment, it not only screens material, the rod of lifting that is connected between two sieve plates also plays a part to hold and lifts material, therefore the requirement of strength of sieve plate self is very high, if improve its intensity own wt is increased greatly, thereby increase the weight of whole set equipment by the increase material thickness.

Three, summary of the invention

The purpose of this utility model is the defective that overcomes above-mentioned technology, provides a kind of simple for production, and high-intensity disintegrating machine sieve plate is to be used for various disintegrating apparatus.

Disintegrating machine sieve plate described in the utility model comprises preceding sieve plate, back sieve plate, preceding sieve plate and back sieve plate split the both sides in disintegrating machine inside, the material lift rod is connected between two sieve plates, wherein the substrate of preceding sieve plate is the arc that has netted sieve aperture, this arc is near evenly being provided with material lift rod location protection seat on the arcwall face of upper end, this protection seat passes arc screening plate, and its center is a material lift rod fixing hole; Back sieve plate is the straight plate with netted sieve aperture, and back sieve plate substrate upper end also is provided with corresponding material lift rod location protection seat and material lift rod fixing hole thereof with preceding sieve plate corresponding position.

Material lift rod location protection seat adopts the casting method monolithic molding with substrate.

After adopting such scheme, can shorten the disintegrating machine material lift rod length that suspends, improve material lift rod bearing capacity, strengthen disintegrating machine sieve plate intensity greatly, improve service life of equipment.
