Background

The steel balls are classified into grinding steel balls, forging steel balls, casting steel balls according to the production and processing technology, and bearing steel balls, stainless steel balls, carbon steel balls, alloy balls and the like according to the processing materials. Among them, the bearing steel ball is widely used in high-speed low-noise bearings, bicycles, motorcycles, automobiles, slide rails, universal balls, cases, electronic industries, grinding media, and the like. Stainless steel balls are commonly used in the hardware industry, artware, plastic products, medical instruments, chemical industry, aerospace, valves, mobile phones and the like. The carbon steel ball is widely used in the hardware industry, iron art, ornaments and the like. The alloy steel ball is a spherical ferroalloy wear-resistant body which is produced by using carbon, chromium, manganese, molybdenum and the like as main added metal elements and through forging, spinning, rolling, casting and other modes, and is the most important component part of the prior ball for crushing industrial mines, cement and the like.

A wear-resistant steel ball is a grinding medium used in a ball mill and is used for grinding materials in the mill. The wear-resistant steel balls are four types: one is white cast iron which takes chromium as a main alloy element and is called chromium alloy cast iron for short; secondly, the casting grinding ball taking the nodular cast iron as the material is called a nodular cast iron grinding ball; the nodular cast iron grinding balls with the matrix structure mainly being martensite, which are obtained by heat treatment, are called martensite ductile iron grinding balls for short; the third is steel ball hot rolled by round steel produced by steel mill; and the fourth method is formed by forging the material of the train wheels.

When the wear-resistant steel balls are processed, due to the process and other reasons, the diameters of the steel balls in different batches and even the same batch have certain differences, and the steel balls with different sizes need to be distinguished after the steel balls are processed. If a manual distinguishing mode is adopted, the screening efficiency is low.

The patent No. 201821507504.2 Chinese utility model discloses a screening and sorting device for wear-resistant steel balls, which comprises a box body, wherein a partition plate is arranged at the upper part of the inner cavity of the box body, the partition plate divides the inner cavity of the box body into a feeding cavity and a screening cavity, the feeding cavity is arranged above the screening cavity, one side of the top end of the feeding cavity is connected with a feed pipe in a through manner, the top end of the feed pipe is connected with a feed hopper in a through manner, the edge of the bottom end surface of the feed hopper is uniformly provided with a plurality of support rods, and the feed hopper is fixedly connected to the top end of the box body through the support rods; the first screening of central authorities through connection of baffle is fought, and first screening is fought and is the cone structure, the first discharging pipe of bottom through connection of first screening fill.

This patent adopts the screening fill that has the mesh to select separately, and the inconvenient dismantlement of screening fill is changed, consequently can only realize the steel ball screening work of three kinds of diameters at most, and the flexibility is relatively poor, to the not fine adaptation of the sorting work of more specifications, exists and improves the space.

Therefore, the wear-resisting steel ball screening machine with the automatic material receiving function is designed, and the problems are solved.

Referring to the attached drawings, the actual outlet is in a triangular shape or an isosceles trapezoid shape, so that the round wear-resistant steel balls can pass through the outlet conveniently.

When the device is used, the servo motor 202 is started to drive the first rocker 202 to rotate, and the second rocker 204 drives the push-pull rod 205 to reciprocate. The push-pull rod 205 moves the first sliding sleeve 306 through the connecting piece 309 and carries the supporting wheel 308 to move synchronously through the fifth strut 307.
