Description

cffife.i

The invention relates to the means of storing and unloading bulk materials using bins and can be used in the agricultural sector of the food industry and other areas of the economy.

The aim of the invention is to improve the accuracy of the metered discharge of bins,

The execution of the cylindrical part of the protective casing of the unloading mechanism from the side of the intake windows with a curvilinear edge cut according to the shape of the screw helix and the introduction of turns of the screw into this cylindrical part is 1.5 steps from the cut edge to the discharge hole located down the center of the bunker, It excludes the possibility of an arbitrary fall of matter through the intake windows into the unloading zone both during the operation of the unloading mechanism and in the quiescent state.

FIG. 1 depicts a bunker device for the flow of the upper terrain 5 general view; in fig. 2 - the same, on top

The bunker device includes a cylindrical body i with a horizontal bottom 2 with an outlet opening 3 which is made thereto, and an unloading mechanism installed inside the housing at the bottom. The unloading mechanism consists of two horizontal screws 4, enclosed in cylindrical protective covers 5 with intake windows, .6, Central part 7 of each protective tip: complete with side edges 8, auger of the screw helix, and covers 1 , 5 steps auger. The protective covers can be equipped with intake guards 9 mounted on their ends, the bottom 2 rests on the supporting rollers 10 and 11 and has the possibility of rotation. The bottom, as well as the pshekov 4, is driven by a drive through gear 12 and 13.

The bunker device for bulk materials works as follows.

Bulk material to be dispensed is loaded into the cylindrical body 1. Under the action of gravity, the material rushes from the top down to the bottom 2 and is located at its density, filling the interturn space of the unloading screws 4 installed in the bottom part

bunker I at the bottom 2 with a gap relative to the latter.

When the device is in operation, the torque from the drive is transmitted to the driving support roller 11 and through the gear train 13 to the shaft of the unloading augers. The driver support roller 11, in turn, transmits torque to a guide attached at the bottom along the perimeter 2, by means of which it travels along the support rollers 10. At the same time, the bulk material located in the lower part of the bunker acquires a rotational circular motion and through the intake ports 6 the housing casing 5 enters the zone of operation of the unloading augers, 4, where the material is picked up by the turns of the screw and is actively moving along the plane of the rotating bottom in the form of increased continuous roller screws from the walls of the housing 1 towards the solid part 7 of the protective casing 5. When the material approaches the solid part 7 of the protective casing 5 from the side of the intake ports 6, its part is located outside the auger, cut off by a curvilinear cut of the hemline of the screw, and disperses throughout the cavity of the housing 1 .

In order to exclude stagnant zones along the periphery near the walls of the bunker I, to the ends, protective covers 5 at an angle opposite the rotation of the bottom 2 are attached to the rear flaps 9, which shift the material incident on them onto the screws.

The mass feed of the device is varied by smoothly varying the frequency of rotation of the bottom 2 and the screws 4.

Making the central part of the protective shrouds solid with edges repeating the shape of the auger helix and covering 1.5 screws of each screw eliminates any loose crumbling of the material into the discharge zone through the intake openings during operation. rest and provides a uniform flow into the zone of unloading of material located only in the inter-turn space between the unloading turns of the screw.

When making a solid part of the ear skin with vertical cuts, the Invention Formula 1 and 1, Bunker device for bulk materials, containing a cylindrical body with a horizontal bottom and a coaxially bore hole in it and a discharge mechanism installed inside the body at the bottom. , including two gomi edges and the location of the unloading turns of the ischecks in the cylindrical part of the casing for a length of less than 1.5 steps, the screw from the edge of the edge is observed intense, I ask for a passing material through the upper corners intake windows between

of the casing part and further through the vial of the auger, enclosed in a cylinder window in the line. At rass-. Lindrical protective covers with the intake position of the unloading turns of the screws in the cylindrical part of the housing for a length of more than 1.5 screw pitch from the edge of the edge of the material are practically absent, but with such a discharge device, the area of the intake windows decreases; leads to an increase in dynamic narrazok on the working body, thereby reducing the reliability of the entire device.

In order to ensure the accuracy of the metered unloading, the central 15 part of each protective screw is continuous with the side edges repeating the shape of the screw line of the screw and covers I, 5 steps of the screw
