Description

(54) BUNKER DEVICE

one

The invention relates to a packaging technology.

A bunker device is known, which comprises a chute body, the edge of the inlet portion of which is formed along an arc of a circle of a hinged fortified sector gate to shut off the chute 1.

However, in the known device, the likelihood of the sectoral shutter jamming when the chute overlaps is not excluded, which reduces the reliability of the bunker device.

The purpose of the invention is to increase the reliability of operation by preventing the shutter from seizing.

The goal is achieved by the fact that in a bunker device, mainly for building mixtures, consisting of a chute body, the inlet edge of which is made along an arc of a circle and a hingedly reinforced sector gate to block the chute, the axis of rotation of the gate is fixed on the wall of the chute, and the inlet section The chutes are made so that the center of its circumference is located on the axis of rotation of the shutter, while one of the walls of the bunker forms an angle of 120-160 ° with the tangent to the surface of the shutter, and the opposite is 90-100 ° respectively.

In addition, the wall of the hopper at the location of the gate and the front edge of the latter have elastic pads.

FIG. 1 shows a bunker device, side view with a partial section; in fig. —a interface of the front wall of the housing with a shutter in various phases of displacement of the latter; in fig. 5 and 6-

10 a gate-to-rear port interface when the shutter is moved.

The device includes a body I with chute 2, the edge of the entrance section of which is made along an arc of a circle and a hinged sector gate 4 d

 overlap the chute 2. The axis of rotation of the bolt 3 is fixed on the wall of the chute 2, and the input section of the chute is made so that the center of its circumference is located on the axis of rotation of the gate. At the same time, the front wall 5 of the body forms an angle of 120-160 ° with a tangent to the trajectory of the gate 4, and the opposite wall 6 forms an angle of 90 ° respectively. In addition, the front wall 5 of the housing in the place of the entrance of the shutter 4 and the front edge 7

the latter have elastic pads 8 and 9.

Zatura works as follows.

To open the shutter, it is turned using a lever (not shown) but arrow A. Since the shutter has the same curvature across the width, there is no gap between the surface of the shutter and the front wall throughout the shutter movement time.

The seizure of material particles between the gate and the front wall is eliminated due to the fact that the angle (Fig. 2) is much more than 90 ° (). This is also accompanied by an elastic gasket.

Thus, the proposed device prevents jamming of the shutter, which increases the reliability of operation.
