Description

The technical field to which the invention relates.

The invention relates to the field of general mechanical engineering, in particular to devices for dispensing and distributing bulk materials, for example, for dispensing and distributing components entering a mixer or feed chopper.

The level of technology.

A metering device for dispensing bulk materials is known, comprising a receiving hopper and a screw system for feeding and dispensing material located in hollow cylinders and equipped with motor drives, as well as control means coaxially mounted metering and compensating screws, the cylinders of which are connected to each other and each is equipped with a hopper, connecting it with a common supply cylinder, while the metering screw is made of a larger diameter and is located at the output of the device, the screw drives are made in the form of gear motors with p adjust- able speed and compensatory screw drive associated with the drive of the metering screw (See. Patent SU №464096 A3, IPC 5 B65G 33/14, publ. 03.15.1975).

The disadvantages of this dispenser are the large overall dimensions, the complexity of the design and the uneven distribution of the discharged material.

A device is known for volumetric dosing of bulk materials, containing a hopper equipped with a tedder with an outlet neck, placed above the slide gate with measured through containers, combined with the discharge channel in the receiving matrix, which is mounted in the tool bed of the bed, where the drive and track control system are located, according to the invention , the tool table is equipped with a vibrator and spring-loaded relative to the bed, and the multi-seat feeder is kinematically closed with a distribution grid of the throat bins of the hopper by means of a damper made in the form of a pressure chamber, while the agitator has the form of cones adjacent to the through channels of the distribution grid of the cones (see patent RU No. 2464535, MKI5 G01F 11/24, published on October 20, 2012).

The disadvantage of the described device is the unsatisfactory functionality and complexity of the readjustment of the tool unit to different volumes of supply.

The closest in technical essence and the achieved positive effect and adopted by the authors for the prototype is a dispenser with a hopper for bulk materials. The dispenser with the hopper contains a housing placed vertically. A loading hole is made in its upper part and an unloading hole in the lower part, which are aligned with the vertical axis of the drive shaft. Two horizontal discs are rigidly fixed on the shaft - one behind the boot, and the other in front of the discharge hole. Each disk has a notch in the form of a sector with an opening angle of less than 180 °. Sectors are shifted relative to each other by 180 °. A cutting knife rigidly fixed to the surface of the hopper body is fixed on the disk behind the loading hole. A horizontal agitator is installed on the vertical shaft of the drive in front of the loading hole with the possibility of adjusting it in height. The invention provides the elimination of the formation of poor-flowing material and stagnant zones in the hopper, as well as improving the accuracy of the dose of the material (see patent RU No. 2433939, B65B 1/00, publ. 11/29/2011).

The disadvantage of this dosing device is the complexity of manufacturing the design and the discreteness of its action due to the presence of sectors offset from each other.

Disclosure of the invention.

The technical result that can be achieved using the present invention is reduced to the dosing of the bulk material entering the grinder, as well as to its uniform distribution in the loading neck.

The technical result is achieved in that in a device for dispensing bulk materials containing a conical body, a rotating conical rotor, a drive shaft, a bearing, a washer, nuts, a support, a conical loading and unloading hole, a pulley, the rotor is made in the form of a cone that rotates and has the ability regulation of the distance between the housing and the rotor, which allows you to adjust the amount of supplied material.

A brief description of the drawings.

The drawing shows a device for dispensing bulk materials cone type.

The implementation of the invention.

The device for dispensing bulk materials contains a conical housing 1, in which a rotating rotor 2 in the form of a cone is inserted, mounted on the drive shaft 3 using a bearing 4 and a washer 5, while the height adjustment nuts 6 and 7 are mounted on a support 8 mounted on the housing 1, having a conical loading hole 9 and a conical unloading hole 10, and the pulley 11 is mounted on the shaft 3 of the rotor drive 2 (Fig.).

A device for dispensing bulk materials of the cone type operates as follows.

Inside the housing 1, through the conical loading hole 9, bulk material is poured, which due to gravity falls onto the rotating conical surface of the rotor 2 and due to centrifugal force is evenly distributed around the perimeter of the conical discharge opening 10. The rotor 2 rotates due to the transmission of torque from the pulley 11 through drive shaft 3. The amount of material supplied to the subsequent device (mixer, grinder, etc.) is controlled by the distance h between the housing 1 and the rotor 2 due to the movement of nuts 6 and 7 along the thread along the drive shaft 3 to a height N. Nut 6, abutting through the washer 5 and the bearing 4 in the support 8 lowers or raises the drive shaft 3, thereby changing the clearance h between the housing 1 by the rotor 2. The nut 7 is used to lock the nut 6 to prevent it from moving relative to the drive shaft 3.

The invention in comparison with the prototype and other known technical solutions has the following advantages:

- universality;

- uniform distribution of seeds around the perimeter of the discharge opening;

- the ability to accurately dose the amount of material;

- ease of implementation.
