Description

Feeding mechanism of winnowing machine

Technical Field

The invention relates to the technical field of material impurity removal equipment, in particular to a feeding mechanism of a winnowing machine.

Background

A winnowing machine, also called an air flow separator, is a device for removing impurities by wind power by utilizing the difference of suspension speeds between materials and impurities, and is commonly used for removing light impurities and dust from materials. The existing winnowing machines for materials with more impurity types, such as crops, and the like, also remove metal impurities contained in the materials by adsorbing by arranging a movable magnet at the feeding part of the winnowing machine. However, this kind of structure of cleaing away metallic impurity, on the one hand adsorption efficiency is powerful inadequately, and the edulcoration effect is not good, and on the other hand, behind the magnet adsorption impurity, need remove the magnet that has inhaled impurity from the feed mechanism of air separator, waste time and energy, be unfavorable for cleaing away the metallic impurity of magnet adsorption fast.

Disclosure of Invention

The invention aims to provide a feeding mechanism of a winnowing machine, which can efficiently adsorb and remove metal impurities passing through the feeding mechanism of the winnowing machine.

The feeding mechanism of the winnowing machine comprises a feeding hopper, wherein the lower end of the feeding hopper is connected with a feeding bent pipe, and the key point is that an annular electromagnet is arranged in the feeding hopper, the bottom of the feeding bent pipe is provided with a discharge outlet, and the discharge outlet is provided with a discharge door capable of being opened movably.

When the air separator is used, the annular electromagnet is connected with a power supply of the air separator in series, when the air separator starts to work, the annular electromagnet is electrified to generate strong magnetism, metal impurities in materials poured into the feed hopper can be fully adsorbed, and the impurity removal effect is obvious; the air separator stop work, the bin gate is opened this moment, and annular electromagnet outage loses magnetism, and the metallic impurity who adsorbs on annular electromagnet loses and adsorbs, and by arranging the bin gate discharge, the metallic impurity of convenient collection separation improves work efficiency in the feeding return bend that falls under the effect of gravity.

Furthermore, the upper end face of the annular electromagnet is an inclined plane, so that metal impurities can be prevented from being accumulated on the upper end face of the annular electromagnet, and the metal impurity separation efficiency is improved.

Preferably, the discharge gate is hinged to the discharge opening through a hinge shaft.

Detailed Description

The following describes embodiments of the present invention, such as shapes and structures of respective members, mutual positions and connection relationships between respective portions, and actions and operation principles of the respective portions, in further detail, with reference to the accompanying drawings.

Referring to fig. 1 and 2, the feeding mechanism of the air separator of the invention comprises a feeding hopper 1, wherein the lower end of the feeding hopper 1 is connected with a feeding elbow 2, an annular electromagnet 3 is arranged in the feeding hopper 1, the bottom of the feeding elbow 2 is provided with a discharge outlet 21, and a discharge door 4 which can be opened movably is arranged at the discharge outlet 21.

When the invention is used, the annular electromagnet 3 is connected with a power supply of the winnowing machine in series, when the winnowing machine starts to work, the annular electromagnet 3 is electrified to generate strong magnetism, metal impurities in materials poured into the feed hopper 1 can be fully adsorbed, and the impurity removal effect is obvious; the air separator stop work, row's bin gate 4 is opened this moment, and annular electromagnet 3 outage loses magnetism, and the metallic impurity who adsorbs on annular electromagnet 3 loses and adsorbs, and by arranging bin gate 4 and discharging, the metallic impurity of convenient collection separation improves work efficiency in the effect gliding of gravity falls into feeding return bend 2. In practical application, the feeding hopper 1 is generally made of stainless steel, and if the separation of metal impurities is to be ensured, the metal impurities adsorbed by the annular electromagnet 3 can be ensured to be discharged out of the discharge opening 21 by knocking the outer wall of the feeding hopper 1.

In a preferred embodiment, the upper end surface 31 of the annular electromagnet 3 is an inclined slope, so that metal impurities can be prevented from being accumulated on the upper end surface 31 of the annular electromagnet 3, and the metal impurity separation efficiency is improved.

Preferably, the discharge gate 4 is hingedly arranged at the discharge opening 4 by a hinge shaft 41. In practical application, the discharge door 4 can also be provided with an electromagnetic switch connected with a power supply of the air separator in series, so that automatic discharge can be realized when the air separator stops working, and the automation is improved.
