SU861210A1 - Device for loading conveyer with buldges on load-carrying band - Google Patents

Description

one

The invention relates to a lifting and transport equipment, in particular to devices for transferring products from a vehicle to a plate conveyor.

Known vibrating feeder, including a hopper, an inclined vibratory flow with a vibrator and an elastic suspension 1.

However, vibroplata is complex in design.

Closest to the invention to the technical essence and the achieved result is a device for loading a conveyor with protrusions on the load-carrying fabric, including an inclined hinged-mounted tray, spring-loaded relative to the frame and having a vibration device 2.

A disadvantage of the known device is the large dynamic loads on the overloaded products and the structural complexity.

The aim of the invention is to simplify the design and reduce the dynamic loads on the product.

This goal is achieved by the fact that the vibration device is made in the form of a lever fixed on the tray with a support installed with the possibility of interaction

with the projections of the load-carrying canvas.

FIG. 1 shows a device for loading a plate conveyor; on

5 of FIG. 2 - lever with a shaking support; in fig. 3 is a section along A-A of FIG. one.

The device for loading the plate conveyor includes vertical posts 1 and 2 on which a rigid tray is fixed.

10 3 with the bottom 4 and side boards 5. The rack 1 is equipped with a hinge 6, and the rack 2 has a spring support 7. On the bottom 4 of the tray 3, the lever 8 is rigidly fixed with the shaking support 9 rotating on the axis 10, and

15 bottom 4 of tray 3 installed with a slope

to the horizon at an angle a less than the angle

sliding the product along the bottom 4 of tray 3.

Plate loading device

The conveyor works as follows;

20, the products 11 with the initial speed are fed to the bottom 4 of the tray 3. In this case, the product either slides along the bottom 4 of the tray 3 with the minimum speed, or is stopped due to the created friction and the shape of the product. When the conveyor 12 is moving, the shaking support 9 of the lever 8 periodically contacts with the protruding parts 13 of the conveyor web. At this contact, the shaking support 9 rotates on the axis, and the lever 8 rises and simultaneously raises the bottom 4 of the tray 3, which rotates around the hinge 6 of the rack 1 and changes the angle a of the tilt of the bottom 4 with respect to the horizon. When the contact of the shaking support of the lever 9 is interrupted

8, with the protruding parts of the conveyor belt, the lever 8 drops abruptly, and the bottom 4 of the tray 3 also abruptly lowers onto the spring support 7 of the rack 2, which absorbs and creates vibration, due to which the product slides along the bottom 4 of the tray 3 onto the plate conveyor. Since the plate conveyor belt is made with constantly alternating protruding parts, the contact of the shaking support

The 9 levers 8 with them constantly occur at short intervals of time (depending on the pitch of the projections and the speed of the conveyor) and, thus, the overload of the products occurs uninterrupted, and the overloaded products enter

on the conveyor with the minimum speed of sliding.

The beneficial economic effect is due. by simplifying the design and eliminating the drive and the plurality of hinges from it, as well as by reducing the dynamic loads on the product.
