SU797979A1 - Vibrated chute feeder for loose materials - Google Patents

Description

one

The invention relates to the storage and unloading of bulk materials, in particular to lottery vibropies, and can be used in such common national households as construction, chemical, food, etc.

A well-known chute feeder for bulk materials is known, which contains a bunker, under a discharge opening of which a spring-loaded chute with a rear end wall and a vibrator mounted on the bottom is hinged, and a mechanism for changing the tilt angle of the tray Sh.

The disadvantage of this vibrating feeder is the limited ability to feed material with a low mobility coefficient due to sticking it around the back wall of the tray and, consequently, causing the feed bulk material to get stuck under the discharge opening of the hopper.

The purpose of the vibrating feeder is to stabilize the flow rate of the bulk material.

The goal is achieved by the fact that the vibrating feeder is provided with an additional vibrator mounted on the rear end wall of the tray, the direction and frequency of which vibration

This does not coincide with the direction and direction of the vibroacoustic sensor, the angle of inclination of the tray and the switching device.

The drawing shows schematically a flow vibratory feeder, a general view.

The chute feeder contains a hopper 1, under the discharge opening 2 of which is fixed to the hinge 3

0 spring-loaded tray 4. The tray has a rear end wall 5 and mounted on the bottom. The driver 6 and the front wall 5 is an additional vibration amplifier 7. The tray vibration receiver is equipped with a mechanism 8 for changing the angle of inclination of the tray mounted on the hopper 1 through a flexible suspension 9, as well as sensor 10 angle tilt tray, and a switching device 11.

The feeder works as follows.

Bulk material coming from hopper 1 is transported along a tray.

1 through vibration generated by the main vibration generator 6. Regul.-. The performance of the feeder is made by changing the angle of inclination of the tray 4 by the mechanism 8.

Claims (1)

Claim Tray vibrator for bulk materials, containing a hopper, under the discharge opening of which a spring-loaded 5 tray with a rear end wall is hinged and with: vibration damper mounted on the bottom, and a mechanism for changing the angle of inclination of the tray, which is different (that, in order to stabilize 0 of the feed rate of bulk material supply, it is equipped with an additional vibration exciter mounted on the rear end wall of the tray, the direction and frequency of which does not coincide with the direction and frequency of the vibration exciter, d a tilt angle sensor and a switching device.
