The utility model relates to devices for the accumulation and unloading of finely dispersed materials, for example, dust, and can be used in systems under reduced pressure in various industries.

Known tray feeder a. from. N 1119948 from 06/30/81, containing a hopper with an outlet, a shutter, a shutter rotation mechanism, an actuator.

The disadvantage of this device is that the complex shutter mechanism is not designed to ensure the tightness of the hopper and, as a result, cannot be used in systems under discharged pressure.

The device can be taken as a prototype.

The technical task of the utility model is to simplify the design of the shutter system with increasing the closure density of the shutter to the discharge opening.

The technical task is carried out due to the fact that the hopper is provided with a shutter in the form of a gate with a sealing gasket in place of touching it with a discharge opening with a rounded edge and a drive located on a multi-arm beam mounted to rotate on an axis fixed above the discharge opening on its vertical axis of symmetry, on a vertical wall. A slide gate is installed on the short arm of the rocker arm and a means for fixing the rocker arm relative to the hopper wall, and a drive is mounted on the long arm.

The different-arm rocker allows you to use the properties of the lever mechanism to reduce the power of the drive, with a wide stroke of the working bodies of the drive, a minimum movement of the shutter bolt is possible, which is important when regulating iota2001131807

bulk material, for example, wad, from the hopper at the time of unloading.

The location of the axis of rotation of the rocker arm above the unloading hole allows you to use the possibility of free sagging of the rocker arm with a slide gate and occupy the exact position opposite the unloading hole. Means of fixation of the rocker arm serves as an additional seal of the slide gate and during the filling of the hopper allows to avoid mixing, slide gate. The rounded edge of the discharge opening increases the durability of the gasket, improves the quality of the seal.

In FIG. 1 shows a hopper on the side.

In FIG. 2 - view of the hopper from the side of the beam.

The housing 1 of the hopper contains a loading pipe 2, in the bottom part of the vertical wall there is a discharge opening 3. On the axis 4, with the possibility of rotation, a different-arm rocker 5 with a short shoulder b and a long shoulder 7 is installed. A slide gate 8 with a gasket 9 is placed on the short shoulder b and means for fixing 10 of the rocker arm 5. A drive (not shown) is mounted on the long arm 7.

The device operates as follows.

After filling the hopper, the locking means 10 is released. By means of a drive (not shown), the beam 5 is rotated on the axis 4, the slide gate 8 with gasket 9 mounted on the short arm b is moved upward relative to the cross section of the discharge opening 3. After releasing the tank body 1 of the hopper, drive (not shown) rocker 5 with slide gate 8 returns to the initial skid and rocker 5 is fixed by means of fixation 10 relative to the housing 1 of the hopper.

Claims (1)

A hopper with a discharge opening comprising a shutter, a shutter rotation mechanism, a drive, characterized in that the shutter rotation mechanism is a rocker arm with shoulders of various lengths, mounted to rotate on an axis located on the vertical axis of symmetry of the discharge opening with a rounded edge, on a short shoulder there is a shutter in the form of a gate with a sealing gasket in place of contact with the discharge opening of the hopper and means for fixing the rocker arm, and a drive is installed on this shoulder.
