The invention relates to the field of technological equipment of the food industry, in particular to feeder hoppers for feeding crushed small-fraction vegetable raw materials to the extractor of an extraction plant of a complex for the production of soft drinks concentrates.

The crushed fine-grained vegetable raw materials, while in the feed hopper, have the property of forming an arch of raw material particles due to their adhesion to each other. This vault interferes with the feed of shredded raw materials through the hopper.

A known hopper with a device for unloading bulk material, comprising a rod with blades mounted inside the hopper, connected to a drive of its helical movement, which consists of a vibrator mounted above the bar and a torsion bar located between the bar and the vibrator, and the blades are turned to the vertical axis rods at an angle. Besides

Moreover, the blades are provided with plates fixed at their ends.

A disadvantage of the known hopper is that when working with chopped fine-grained vegetable raw materials, the feed efficiency through the hopper decreases, since neither the blades themselves, nor the plates at their ends can destroy the arch of particles of chopped grass due to the fact that rotation occurs along a strictly defined trajectory around the rod and moving it along its axis from the vibrator (the length of movement along the axis is limited).

In addition, the rod drive is cumbersome in design, cumbersome, and requires the introduction of elements for vibration isolation, since it is necessary to simultaneously ensure the rotation of the rod around the axis and vibration movement along the axis.

The purpose of the proposed hopper-feeder is the ability to supply crushed fine-grained vegetable raw materials.

This goal is achieved by the fact that a clamp is fixed on the free end of each horizontal sprinkler-agitator of the collapsing device, on the axle axis of which between the eyes with the possibility of rotation in mutually perpendicular planes through the bracket there is an inertial bar, while the loading hatch of the hopper lid is equipped a gate feeder connected to a cyclone-precipitate under the supply line for pneumatic transport of small-fraction raw materials, and the receiving divider with a vibrator and a discharge screw installed coaxially with the discharge opening of the hopper below its level. In addition, the receiving divider is connected to the discharge opening of the hopper through an elastic guide pipe.

Figure 1 shows a General view of the hopper feeder; in Fig.2 - section aa in Fig.1; in Fig.Z - section bB in Fig.1; Fig. 4 is a view of B in FIG. 3; figure 5 is a section GG in figure 4; in Fig.6 is a view of D in Fig.5.

The hopper-feeder has a stand 1, on the upper ends of which the conical body 2 of the hopper is attached (see Fig. 1). On the upper part of the housing 2, a round sheet cover of the feeder hopper 3 is installed, and a ladder 4 is attached to the surface of the housing to provide access to the equipment. The cover 3 has a loading hatch 5, on the flange of which a lock feeder b is installed (see Fig. 2 ) The gateway feeder 6 is equipped with a gear 7 located on the shaft 8 of the drive of the gateway feeder (the drive of the feeder is not shown conventionally). The lock feeder is hermetically connected to the cyclone precipitator 9. In the center of the cover 3, a sleeve 10 is welded with a rubber sealing ring 11 (see Fig. 3). Two kerchiefs 12 are welded to the upper part of the cover 3, which serve as a support for the vertical sheet 13, on which the drive of the collapsing device is assembled, consisting of an electric motor 14 and a worm gear 15. A vertical rod 17 is attached to the vertical shaft of the worm gear 15 with a clutch 16 a collapsing device which is mounted inside the sleeve 10 with the possibility of axial rotation and extends along the central vertical axis of the conical body 2 to its lower part On that part of the vertical rod 17, which is located its inside the housing 2, welded in several horizontal planes of the crossbar 18 whose length is depending on the diameter of the circumference of the housing 2 in this horizontal plane

(see FIG. 4). At the free end of each horizontal bar 18, a clamp 19 is fixed, which is secured by a bolt-axis 20 and a nut 21, while between the eyes

Clamp 19 remains clearance (see Fig. 5). On the bolt-axis 20 between the eyes of the clamp 19 with the help of the bracket 22, an inertial bar 23 is inserted with the possibility of rotation in mutually perpendicular planes (see

0 Fig. 6). An output flange 24 is attached to the lower part of the housing 2, which forms the discharge opening of the hopper-feeder and has a special juice for fastening the elastic pipe 25. Elastic

5, the pipe 25 with its lower end is attached to a special ske located on the upper part of the vibration chamber 26, to the outer surface of which a vibrator 27 is rigidly attached. Inside the chamber 26 to

0 of its upper part, the receiving divider-activator 28 is rigidly fixed, vibrating together with the chamber 26 in the discharge opening of the output flange 24. At the bottom of the chamber 26 there is a discharge

5, a screw 29 which is not in contact with the vibrating parts of the hopper. One end of the discharge screw is connected to the electric drive 30, the other end of the screw is enclosed in the discharge pipe 31, the outlet pipe of which ends above the filler neck of the extractor 32. The vibration chamber 26 by means of springs 33, as well as the discharge pipe 31 in the electric drive 30 are assembled on a bed 34,

5 which is located on the base stand 35.

The hopper operates as follows. From the supply line of pneumatic conveying, finely divided

0 plant material enters the precipitation cyclone 9 and settles in its lower part and in the upper part of the lock feeder 6. filling the space between the gear teeth 7, the drive of the lock feeder rotates the shaft

5 8 with gear 7 mounted on it and

plant material between

gear teeth moves from the upper part of the airlock feeder to the lower

part and pours out through the loading hatch

0 5 in the cover 3 into a cone-shaped housing 2, and due to the absence of a gap between the gear teeth and the gateway feeder housing, the tightness of both the cyclone precipitator and the pneumatic transport line 5 is maintained.

The electric motor 14 through the gearbox 15 and with the help of the clutch 16 rotates the vertical rod 17 of the collapsing device, while the horizontal crossbars 18 are evenly leveled

plant material in the housing 2. If the level of plant material exceeds the level of any tedder rod, then the inertial bar 23 mounted on it moves behind the tedder rod in a horizontal position and does not create additional forces for rotation of the arbor-breaking device. As the level of plant material decreases below the agitator rod, the inertia bar 23, turning by gravity on the bracket 22 around the bolt axis 20, presses the upper layer of plant material with its mass, pushing it along an inclined wall under the next agitator rod. Thus, from the upper to the lower part of the housing 2, the inertia bars 23 eliminate the possibility of arch formation of the vegetable raw material and ensure uninterrupted supply to the lower part of the hopper. The vegetable raw material, entering the lower part of the housing 2, enters the fluidization zone, which is formed due to the fact that the receiving divider-activator 28 located in the discharge opening of the output flange 24 undergoes oscillatory movements, since it is rigidly connected to the vibration chamber 26 and a vibrator 27. Vegetable raw materials under the influence of oscillations of the ribs of the cutter-activator 28 pseudo-fluidizes and enters into the vibration chamber 26, where the density of the vegetable raw material is stabilized. The activator divider also provides smoothing of the pulsation of the flow of vegetable raw materials exiting the housing 2. The elastic pipe 25 allows the hermetically fixed output flange 24 to be connected to the vibrating chamber 26, which eliminates the possibility of dusting the working room. The compacted plant material from the chamber 26 is moved by a screw 29 through the discharge pipe 31 to the outlet pipe of the discharge pipe and enters the feed neck of the extractor 32.

Thus, the proposed hopper-feeder provides the efficiency of the supply of small-fraction vegetable raw materials through the hopper-feeder.
