Description

BACKGROUND OF THE INVENTION The invention relates to bunker devices and can be used in industry in the field of storage, weighing and dosing of bulk materials.

The purpose of the invention is the expansion of technological capabilities through the use of a shutter in weighing batchers and an increase in the reliability of the shutter operation by self-locking the shutter.

The presence in the gate of the tambour, on which the rotary disk is mounted eccentrically, creates an opportunity for lateral movement of the valve attached to the disk, i.e. its movement is almost in the plane of the outlet of the bunker. This creates the possibility of introducing the free end of the flap into the gap between the hook and the bunker, which ensures its

self-locking. The presence of a cable embracing the disc and connected at one end with a hook and the other through a spring with a tang allows one to create a rotational drive of the flap with simultaneous disengagement of the hook, synchronizing this operation with the transverse movement of the flap. Such a design creates conditions for the damperless closing of the valve, which is necessary in the operation of the weighing feeders.

Figure 1 shows the stopper of the hopper, the closed position; figure 2 is the same, the open position.

The gate of the hopper 1 for the weighing dispenser mounted on the cantilever 2 weighing device contains mounted on the hopper by means of axis 3 an axis 4. On the latter, the disk is mounted with the possibility of rotation

5 by axis 6. A disk 7 is fixed on the disk 5. A hook 8 for fixing the valve in the closed position is fixed to the hopper by means of a hinge 9 and spring loaded 10. The valve has a cable 11. covering the disk 5 and connected to the hook 8 at one end - by means of a spring 12 with a 3-axis 4 axis. To prevent slipping, the cable 11 is fixed on the disk 5 with a clamp 13. The disk 5 is provided with a stop 14 of its rotation. The shutter also includes a drive mechanism 15 (an electromagnet, a pneumatic cylinder, etc.) with a lever 16 and a protrusion 17 on a master 4 for interacting with the lever 16.

The gate of the bunker works as follows.

Under the influence of the drive mechanism 15, the lever 16 acts on the protrusion 17, causes the pilot 4 to swing (figure 1) from left to right. At the beginning of this movement, the disk 5 practically does not rotate, and the flap 7 makes a slight movement in the plane of its location (plane of the outlet of the bunker), providing some slight exit of the flap edge of the flap 7 from the gap between the hook 8 and the bunker 1. With further progress of the tambour 4 when the spring 12 is so tight that it overcomes the force of the spring 10, the cable 11 tensions open the hook 8 and this tension serves to turn the disk 5 on the axis 6. As a result of turning the disk 5 behind Lonka 7 also performs a rotary motion and opens an outlet opening of the hopper 1 (Figure 2).

To close the outlet of the hopper 1, the drive mechanism 15 releases the lever 16, which, returning to the initial position, releases the protrusion 17 of the tandem 4. Under the action of the extended spring 12, the tang 4 begins to move in the opposite direction, and the disk 5 also begins to rotate back side and

the flap 7 closes the outlet of the hopper 1. Simultaneously with these movements of the mandrel 4 and the disk 5, the cable 11 is gradually released and the hook 8

returns to its original position, close to the position in FIG. 1. Before the end of the movement of the tang 4 and the rotation of the disk 5, the flap 7 actually closes the outlet of the hopper 1 and the hook 8 takes

close to extreme closing position. At this point, the rotation of the disk 5 ends, as the limiter 14 rests on the tandem 4, and the last one, ending its swinging advance (from right to left),

pushes the flap 7 into the gap between the bottom of the hopper 1 and the hook 8, which also at this moment is located in its final position, into which it enters due to the release of the cable 11 and the action

springs 10.

With this shutter, when closed, the hopper is kept in a stable condition, there is no shock excitation and swing of the cantilever.
