Stock receiving device for air hoister

Abstract

The invention relates to a material accepting device of a pneumatic lifter. The material accepting device mainly comprises a feeding tube and an outer sleeve and is characterized in that the feeding tube consists of a buffer tube 1 of an upper section and an accelerating tube 2 of a lower section, a feeding base 5 is arranged under the accelerating tube 2, wherein, a plurality of air inlets 11 are arranged above the feeding base 5 and a plurality of feeding ports 12 are arranged under the feeding base 5; an adjusting disc 8 of the end port of the feeding base 5 is fixed on a ground fixed disc9 by screws, the outer sleeve 3 is sheathed outside the feeding base 5 at the lower section of the accelerating tube 2 and the lower end of the outer sleeve 3 is also provided with feeding ports 13 which are matched with the feeding ports 12 mutually. The material accepting device has the advantages that (1) the pressure of the materials can be quickly reduced after being buffered by the buffer tube 1 after the accelerating lift of the accelerating tube 2, therefore, the impact between the materials and the top part of the discharger is reduced and the crushing rate of the material is effectively reduced; (2) wind speed is lowered after the material is buffered by the buffer tube 7, the resistance of wind pressure is decreased and the wind resistance loss is reduced; (3) since the weight of the whole machine is fixed on the ground fixed disc, the gravity center of the whole machine is stable, the lifter is not needed to be hung on the beam of a house by an iron wire, and the usage is safe and reliable.

Description

technical field [0001] The invention relates to a material receiving device of a pneumatic lifter used for material lifting of solid particles (paddy, wheat, brown rice, corn, etc.) on the pneumatic lifter. Background technique [0002] The material receiving device on the air lifter with the patent No. 90221521.3 in the prior art is mainly composed of a feed pipe and an outer casing; the connection and structure between them are: the lower end of the outer casing is connected to the feeding chassis and installed In the discharge pit for granular materials, the upper end of the feeding pipe is connected to the unloader on the elevator, and the lower end of the feeding pipe is inserted into the outer casing. There is a gap between the outer wall of the feeding pipe and the inner wall of the outer casing, causing the feeding pipe It cannot be stably fixed on the ground, so the entire weight of the air lift composed of the unloader connected to it, the motor on the unloader, th...

[0002] The material receiving device on the air lifter with the patent No. 90221521.3 in the prior art is mainly composed of a feed pipe and an outer casing; the connection and structure between them are: the lower end of the outer casing is connected to the feeding chassis and installed In the discharge pit for granular materials, the upper end of the feeding pipe is connected to the unloader on the elevator, and the lower end of the feeding pipe is inserted into the outer casing. There is a gap between the outer wall of the feeding pipe and the inner wall of the outer casing, causing the feeding pipe It cannot be stably fixed on the ground, so the entire weight of the air lift composed of the unloader connected to it, the motor on the unloader, the fan and the dust collector can only be hoisted on the girder of the house with wire

When the air lift is working, due to the continuous operation of the motor and fan, the unloader of the air lift will be displaced after a long time, which will easily cause the wear and damage of the feeding pipe

In addition, since the upper and lower thickness of the feeding pipe is the same, when the air hoist is lifted, the speed at which the granular material enters the feeding pipe remains unchanged, and the granular material hits hard in the unloader due to its high speed, resulting in a high breakage rate.
