Abstract

The invention relates to mechanical engineering and is associated with the mechanization and automation of processes for overloading and dosing bulk materials. The purpose of the invention is to simplify the design. A distinctive feature of the proposed device is that the dispenser gate actuator is adapted to vertically move both relative to the funnel itself and to the fixed case, and the configuration of the lower part of the guide corresponds to the path of the free arm of the shutter lever when opening and closing the discharge hole of the funnel, and the upper part of the guide has a T-shaped stop. 5 il.

Description

 The invention relates to devices for handling and metering loose, easily damaged agricultural products and can also be used in food, chemical, construction and other sectors of the national economy.

The purpose of the invention is the VnponieHHe design.

FIG. 1-4 shows the device in different phases of the workflow; in fig. 5 - axonometric image of the device.

The device consists of a fixed body 1 (Fig. 1) with a loading mechanism, an elastic sleeve 2, a receiving funnel 3, which is vertical, but is moved by means of a mechanism 4 of the type of Nuremberg scissors (Fig. 4), the axis of the articulated connection is installed in horizontal directions 5 and 6 (Fig. 2), and the axis

the hinge joint of two links of this mechanism, hinged to the body, is rigidly connected to the seat 7 of the calibrated spring 8. The opening and closing of the discharge hole of the funnel occurs under the action of the material by means of a bolt consisting of a two-arm lever 9 hinged at the bottom parts of the funnel and movable copier guide 10, which can be installed both on the fixed hull structure and on the funnel (in Figures 1-5, the guide is shown mounted on the metering unit).

At the upper end of the movable guide there is a T-shaped stop in contact in the extreme upper position with the fixed hull structure and funnel, and in the extreme lower position only with the fixed hull structure, and

its lower section corresponds to the trajectory of movement of the roller 11 (Fig. 5) of the free arm of the two shoulders lever (not in contact with the motherboard), which ensures the full opening and closing of the dispensing opening of the dispenser at its extreme positions.

In order to turn off the drive of the loading mechanism (conventionally not shown in Figs. 1-5), when the specified weight of the material in the metering unit is reached, a limit switch 12 is installed on the hopper (Fig. 3 in contact with the calibrated spring of the spring. In addition, the device contains fixed in the lower part of the housing limiter 13.

The proposed device works as follows.

In the absence of material, the funnel 3 (Fig. 1) is in its extreme upper position and does not interfere with the entrance of the vehicle with the container mounted on it. When the container is installed at a predetermined position, the loading mechanism of the housing 1 is actuated and the material enters the funnel through the elastic sleeve 2.

As the material arrives, the funnel is lowered by means of a vertical movement mechanism, overcoming the resistance of the calibrated spring 8 (Fig. 2), and the required positioning accuracy of the gate relative to the container is ensured by the rigidity of the links of the mechanism, made in the form of Nuremberg scissors, and the presence of horizontal guides 5 and 6, mounted on the body and funnel.

Together with the funnel in contact with the T-o6pa3HbLM stop, due to its own weight and friction on the roller 11 of the free arm of the two shoulders of the lever 9, the movable guide 10 is lowered as far as it will go into the fixed structure of the housing 1 (Fig. 3).

Further flow of material into the funnel leads to the fact that the funnel, overcoming the friction of the roller of the free shoulder of the two shoulders of the lever on the stopped guide, lowers into KpafiHee the lower position at which the configuration of the lower part guide does not interfere

24hoBopoTy free shoulder two shoulders. At the same moment, the end switch 12 contacts the seat of the calibrated spring and the drive of the loading mechanism is turned off. As a result of the two-arm lever turning under the weight of the material, the shutter opens and the material is fed in a continuous flow into the container.

As the overload spring 8 (Fig. 4) expands and moves the funnel to its original position along with the movable guide 10 and the open shutter, because to close the shutter due to the sharply increasing coefficient of friction of the roller on the lower portion of the guide .

As a result of a joint lift, the guide 10 rests on the T-shaped stop into the stationary structure of the housing 1, and the funnel continues to move and, having overcome the friction of the roller 11 on the lower portion of the guide due to the spring force, returns to its original position. At the same time, the free arm of the lever 9 rolls around the path of the lower portion of the guide 10, turning the shaft to its original position, as a result of which the discharge opening closes.
