Description

The utility model relates to the mechanization of loading and unloading operations, in particular to devices for loading bulk materials, including those with a reduced angle of repose and a low flow rate.

Known feed loader containing a bunker in the form of vertical sections, which is installed on a vehicle, in the lower part of the sections of the bunker is placed a feeding screw conveyor, connected in series with a vertical screw conveyor and an unloading auger conveyor, in the casing of the latter of which are located above the bunker sections unloading windows with flaps , a loading conveyor connected by means of an intermediate unit with the rear end of the supply conveyor and a drive mechanism, while the loading conveyor is made in the form of a spiral placed in a flexible casing, having a direction of turns opposite to the direction of winding of the supply screw conveyor (SU 1759343, IPC А01К 5/00, publ. 07.09.1992).

A device for loading rolling stock with bulk cargo is known, containing a straight cylindrical body, inside which a bevel gear box is fixed on the spacer vertical ribs connecting the vertical shaft with the horizontal shaft, while the horizontal shaft is brought out through the wall of the body and connected to a drive, for example, a geared motor (SU 1034973, IPC B65G 67/20, publ. 08/15/1983).

Known a screw-type dispensing machine, including a frame, a feed hopper and a lower hopper in the frame, connected to a horizontal channel and a vertical channel, which is used to circulate material between the feed hopper and the bottom hopper, while a horizontal centrifugal dispenser is built into the feed hopper, the hopper is also mounted has a hinge, and the bottom of the hinge is connected to a perpendicular screw feed, from the top, the bottom of the hopper is connected to the outlet channel, which is connected to the packaging container (CN204587347 (U) - 2015-08-26).

Known dispenser for a filling and packaging machine, containing a loading hopper connected to a horizontal screw chamber with an axleless spiral conveyor, a vertically oriented storage hopper, equipped in the lower part with a product cutter, controlled from the signal of the strain gauge sensor of the control system. Inside the storage hopper, an opener with a geared motor is installed coaxially with it. In this case, the dispenser is additionally equipped with a dosage container located vertically under the storage hopper and equipped with a second product cutter controlled by a signal from a strain gauge sensor. The base of the batching container is installed on the console of the strain gauge sensor, the baking powder consists of an axial shaft with stirring elements, the upper end of which is connected to the gear motor, and the lower end is free, and the stirring elements are oriented along the walls of the storage bin (RU 2483992, IPC B65B 3/08; B65B 1/12, publ. 10.06.2013)

A device for loading and evenly distributing bulk material inside the car is known, which is a rotary column carrying a screw introduced into the car, enclosed in a casing, above the rear end of which a loading funnel is installed, while the front part of the screw is made open (SU 127950, publ. in the "Bulletin of Inventions" No. 8, 1960).

The disadvantages of the known devices are: increased metal and energy consumption, the complexity of the design and technological process, insufficient uniformity of loading and the use of specially equipped cars (containers) for loading.

The author's task is to create a constructively simple and effective device for uniform lateral and vertical loading of bulk materials into covered railway freight cars of any type, as well as river and sea vessels, containers and spherical storages.

The problem is solved due to the essence of the claimed device, which consists of a frame on which a housing with a charging chute is installed, inside which a drive screw shaft is installed, at one end of which an impeller with blades is installed, closed by a housing with an outlet pipe, on which a flexible pipe is mounted, through which the material is fed into the loading container.

FIG. 1 shows the claimed device in frontal section.

FIG. 2 shows a general view of the inventive device with a motor.

FIG. 3 shows an example of the claimed device with a belt drive electric motor.

FIG. 4 shows the impeller housing with a flexible tube.

FIG. 5 shows an example of a flat blade impeller.

The device consists of a welded auger body 2, fixed on a frame 1, with a loading chute 3 of rectangular cross section, inside which, on end bearings 4, a drive auger shaft 5 is installed, at one end of which an impeller 6 is installed, made in the form of an impeller with blades 7, from the outside, the impeller 6 is closed by a housing 8 with an outlet 9 of a circular cross section, at the end of which a flexible pipe 10 is mounted, through which the material is fed into the loaded container. The screw shaft 5 is driven by a motor 11, for example, a belt drive motor 11a, an electric motor with a clutch (not shown in the figure), etc. The blades 7 can have a flat or other shape to ensure the greatest possible capture of the supplied material.

The principle of operation of the device (using a belt drive electric motor).

The material, through the loading chute 3, is fed into the housing 2 of the auger installed on the frame 1. Further, when the auger shaft 5 rotates, the material is uniformly fed to the impeller 6 with blades 7, which gives the material centrifugal acceleration and, through the flexible pipe 10, is directed to loading capacity.

In the description of this example of the operation of the claimed device, the screw shaft 5 receives a rotational movement from the electric motor 11a through a belt drive (Fig. 3), consisting of a belt 12, driven pulleys 13 and driving 14.

The inventive device allows for horizontal and vertical loading of bulk, fine-grained material into covered railway cars, river and sea vessels, containers and spherical storages, without additional work on leveling the material, thanks to the impeller with blades, which provides centrifugal acceleration of the filled material and a flexible pipe, which allows direct the stream of the loaded material evenly distributing it over the loaded container.

Thus, the task assigned to the author has been completed.
