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

The material-receiving device of Pneumatic lift

Technical field

The present invention relates to be used for the material-receiving device of a kind of Pneumatic lift of using on the Pneumatic lift that the material of particle strong (paddy, wheat, brown rice and corn etc.) promotes.

Background technology

The patent No. of the prior art is that the material-receiving device on 90221521.3 the Pneumatic lift mainly is made up of feed pipe and outer tube; Connection between it and structure are: outer tube lower end and charging chassis join and are installed in and pile up in the blanking hole that granular material is arranged, feed pipe upper end is communicated with discharger on the gig, insert in the outer tube lower end of feed pipe, gapped between feed pipe pipe outer wall and the outer tube inside pipe wall, cause feed pipe can't be stably fixed at ground, therefore the whole weight of the Pneumatic lift of the discharger that is attached thereto, the electrical motor on the discharger, blower fan and dirt collector composition can only be lifted on the crossbeam in house with iron wire.When Pneumatic lift was worked, because the running that electrical motor and blower fan do not stop, of long duration will making caused the wearing and tearing and the damage of feed pipe easily at the displacement of Pneumatic lift discharger.In addition, thickness is the same up and down owing to feed pipe, and when Pneumatic lift promoted, the speed about granular material enters in the feed pipe was constant, and granular material clashes into severe in discharger owing to speed is too fast, the percentage of damage height.

Summary of the invention

The objective of the invention is shortcoming at the existence of the material-receiving device on the Pneumatic lift in the above prior art, can be on the ground and provide that design is a kind of with the weight held stationary of Pneumatic lift complete machine, need not Pneumatic lift is hung on the crossbeam, and can reduce a kind of material-receiving device of Pneumatic lift of the percentage of damage of granular material.

The technical scheme of the material-receiving device of Pneumatic lift of the present invention is: a kind of material-receiving device of Pneumatic lift, mainly comprise feed pipe and outer tube, it is characterized in that: feed pipe is made up of the buffer tube 1 of last joint and the accelerating tube 2 that saves down, the upper end of buffer tube 1 is communicated with the discharger of gig, accelerating tube 2 belows are provided with a charging seat 5, the top of charging seat 5 is provided with several admission ports 11, several inlet points 12 are arranged at the bottom, charging seat 5 belows are provided with an adjustment disk 8, adjustment disk 8 usefulness locking governing screw 10 is fixed on cement and is fixed on the ground reaction plate 9 in the receiver 4, outer tube 3 is enclosed within outside the charging seat 5 of 2 times joints of accelerating tube, gapped between outer tube 3 inside pipe walls and the accelerating tube 2 pipe outer walls, outer tube 3 lower ends are also corresponding to be provided with the inlet point 13 that the inlet point 12 with charging seat 5 cooperatively interacts.

The material-receiving device of Pneumatic lift of the present invention compared with prior art has following advantage: (1) material accelerating tube 2 quickens to promote after can rapid depressurization after buffer tube 1 buffering, reduce the impulsive force at material and discharger top, can effectively reduce the percentage of damage of material.(2) material is low through buffer tube 1 buffering after wind prompt drop, the blast resistance force diminishes, and windage loss reduces, and effectively saves energy is more than 30 percent.(3) because charging seat 5, accelerating tube 2 and buffer tube 1 all adopt heavy seamless steel pipe, can prolong more than 5 times service life.(4) on the ground reaction plate of the weight of this machine complete machine because of the base that is fixed on material-receiving device, machine gravity is stable, does not need to be lifted on the crossbeam in house with iron wire, and is safe and reliable.
