Description

(54) DEVICE FOR LOADING BULK

one

The invention relates to devices for handling bulk materials and can be used in the food, chemical, construction and other sectors of the national economy.

A device for transferring bulk materials is known, comprising a hopper, a loading mechanism and an elastic sleeve, a receiving funnel with a discharge opening and a shutter and a mechanism for the vertical movement of the funnel 1, located below it.

A disadvantage of the known device is the unreliability of operation, due to the presence. electromagnetic drive.

The purpose of the invention is to increase the reliability of work.

The goal is achieved by the fact that the device is equipped with at least one closed guide fixed on the bunker and a spring-loaded lock installed in the upper part of the said guide, and the shutter is made in the form of a two-armed lever hinged on the funnel with the possibility of placing one of his shoulders in the unloading material

the hole of the funnel, and the other with the ability to move along the guide.

In addition, the vertical section of the guide is made telescopic and is equipped with a limit switch connected to the power supply circuit of the loading mechanism.

FIG. 1 shows the device, a general view; in fig. 2 the same, side view; in fig. 3 - the same at the time of unloading of the material; in fig. 4 - shutter.

The device consists of a stationary bunker I with a loading mechanism 2, an elastic sleeve 3, a funnel 4, which vertically moves by means of a mechanism like the Nuremberg scissors 5, an axis. The 15 articulated joints of which are mounted in horizontal guides 6 and 7, and the axis of the articulated connection of two links of this mechanism, articulated with the bunker, is rigidly connected to the seat 8 of the calibrated spring 9. Opening

20 and the loading hole of the funnel is closed — by the action of the material by means of a shutter consisting of a double-arm 10 and pivotally fixed in the lower part of the funnel, and a fixed, closed guide 11 attached to the bunker. In this guide, the free shoulder (not in contact with the material of the two shoulders lever) is moved clockwise using the roller 12 fixed at its end. To move the roller along the Guide clockwise and thereby avoid carrying the valve, it opens the valve at the top in time the guide is installed spring-loaded latch 13.

In order to turn off the drive of the loading mechanism at the moment when a given weight of material is reached, which is located in the funnel at the lowest section of the guide, a limit switch 14 is installed, and this section is made telescopic.

The device works as follows.

In the absence of a product, the funnel 4 is in the upper position and does not prevent the entrance of a transport vehicle with containers installed on it. When the container is installed at a predetermined position, the loading mechanism turns on. Due to the rigidity of the links of the mechanism, made in the form of the Nuremberg scissors, and the presence of horizontal guides 6 and 7 mounted on the feeder hopper and metering hopper, the required accuracy of the positioning of the gate of the hopper relative to the container is ensured. At the same time, the roller 12 rolls around the vertical section of the guide 11. As soon as the weight of the material in the funnel reaches a predetermined value, the drive of the loading mechanism is turned off as a result of the contact between the roller 12 and the final switch 14. At this time, the movement trajectory of the roller in the guide changes that does not interfere with the rotation of the lever 10 under the action of the weight of the material being loaded at a certain angle around its own axis and thereby opening the shutter, resulting in a continuous material eye fed on the conveyor.

As the overload spring 9 expands and moves the funnel to its original position. In this case, the roller 12 moves upwards along the guide 11 and, after full unloading, ensures the shutter closes by turning the lever 10 around its axis. The upward movement is stopped after the shutter is completely closed, which corresponds to the upper position of the roller 12 in the guide 11. Next, the cycle of operation of the device is repeated in the same sequence.

The use of the proposed device allows preserving the quality of the product stored for long-term storage, automating the process of overloading and dosing, as well as increasing the reliability of the device.
