Abstract

The utility model discloses an activating material supplying machine which pertains to the under storehouse coal supplying device. The utility model consists of a material box, a vibrating motor and a damping spring; the material box is provided with a material conducting plate; the upper part of the material conducting plate is higher then the upper end surface of the material outlet box and extends into the outlet of the material storehouse; the connecting line between the edge of the material conducting plate and the edge of the material outlet in the bottom of the material box and the horizontal surface form an inclined angle alpha which is equal or smaller than the rest angle of the material; the size of the material outlet in the bottom of the material box is adjustable; the two sides of the material box is symmetrically provided with two vibrating motors which are arrayed vertically and rotate in the opposite direction in the horizontal line to realize the material outlet function of the material in the lower part of the activating material storehouse. The relative position between the material plate and the material outlet is able to ensure e normal material outlet and the self locking of the material when the machine stops according to the different rational designs of the rest angles of the different materials. The whole material box is supported by four springs. The utility model has the advantages of simple structure and reliable operation.

Description

A kind of activation feeder

Technical field

The utility model belongs to the dispensing equipment under the feed bin.Be specifically related to a kind of activation feeder.

Background technology

Feeder is to be used for block, granular mixture material evenly are given to the equipment that goes the material receiving device continuously or quantitatively from storage bin or funnel under the storehouse.All need hopper wall vibrator be installed at feed bin discharging opening place at present, to prevent the generation of feed bin lower part outlet place putty phenomenon.Also be provided with gate at the feed bin discharging opening, so that in the stop phase blocking-up materials flow of intermittently giving material or regulate feeding coal, this just makes the whole height of feed bin increase, and the existence of gate makes the feeding system complex structure.

Summary of the invention

The purpose of this utility model provides a kind of improved feeder, and it has the effect of activation feed bin lower part outlet place material, and is simple in structure.

The technical solution of the utility model is: a kind of activation feeder, comprise hopper, vibrating motor, damper spring etc., in hopper, be provided with stock guide, high feed box upper surface, stock guide top and being deep in the bin outlet, the inclination alpha that forms between line between stock guide edge and the hopper bottom discharge mouth edge and the horizontal surface equals or is slightly less than the angle of repose of material, hopper bottom discharge mouth adjustable size.When hopper produced horizontal vibration under the vibrating motor effect, stock guide carried out " activation " to the obstruction material in the bin outlet place certain limit.And the gap that forms between stock guide bottom and the hopper inwall is the materials flow passage, and this passage makes material smoothly by flowing to feeding equipment when feed; And when vibrating motor is out of service when feed not, because being the inclination alpha that forms between line between stock guide edge and the hopper bottom discharge mouth edge and the horizontal surface, the inclination angle of hopper inwall is equal to or less than the angle of repose of material, make the material self-locking, can under the pressure effect of storehouse, not flow into feeding equipment, play gate.

In order further to improve the blanking effect, described vibrating motor adopts two, installs in the bilateral symmetry of hopper, vibrating motor is arranged vertically (being that axis of revolution is perpendicular to horizontal surface), do backward rotation, make the straight-line oscillation of hopper horizontal direction, realize the function of activation feed bin lower part outlet material and blanking.The size of feed bin lower part outlet, according to the different appropriate design of heterogeneity material angle of repose, and adjustable.

Its good effect is: because the vibration of hopper self does not need special doffer with the top material activating, reduced the entire machine height; Utilize the self-locking action of material to remove gate from; The structure of whole feeder is greatly simplified.

Description of drawings

Below in conjunction with accompanying drawing and enforcement profit the utility model is further specified.

Fig. 1 is a front view of the present utility model;

Fig. 2 is a lateral plan of the present utility model.

Among the figure 1, hopper, 2, flitch, 3, vibrating motor, 4, spring, 5, motor cabinet.

The specific embodiment

As shown in Figure 1, 2, the activation feeder comprises hopper 1, vibrating motor 3, damper spring 4, is provided with stock guide 2 for 1 li at hopper, high feed box upper surface, stock guide 2 tops and be deep into certain distance in the bin outlet; Vibrating motor 3 is fixed to the both sides of hopper 1 by motor cabinet 5, and for symmetry, be arranged vertically; Flitch 2 is welded on the top of casing, forms a certain size angle α with discharging opening, and the size of feed bin lower part outlet is according to the difference of heterogeneity material angle of repose and difference, to guarantee the requirement of discharging and self-locking; Casing 1 lower raft is made certain radian; Whole box body 1 is by 4 supportings of four springs.
