Abstract

The device is designed for peeling grain and can be used in individual and farm enterprises.

The device for peeling grain contains a housing 1, with a discharge pipe 3 fixed therein, a rotor 4 located in the housing, mounted on a vertical shaft 5, a drive 7 and a reversing variator 8, and the side surface of the rotating deck 6 in the form of a truncated cone is made of metal mesh whose hole diameters are smaller than the equivalent grain diameter. The receiving device 2 mounted on the housing is made in the form of an external pipe 9 of diameter d, with an internal pipe 10 of diameter d / 3 installed in it and connected by jumpers.

The design of the receiving device allows you to feed the processed product through the external pipe into the device for peeling grain, and the air flow will flow unhindered into the working area of the rotor rotor through the internal pipe. The resulting air-grain mixture is accelerated by a blade rotor, takes off from it and hits the side surface of a rotating deck in the form of a truncated cone. Peeling of the grain is carried out due to the impact of grain on the deck and the interaction between themselves in the air-grain mixture. Peeling products are removed from the device through the discharge pipe. The additional air flow entering through the inner pipe facilitates the intensive movement of the air-grain mixture in the device, the removal of peeling products from it, and is used to further separate them into fractions.

Description

The device is designed for peeling grain and can be used in individual and farm enterprises.

Known grain husk (RF patent No. 2446885, B02B 3/08), comprising a housing with loading, unloading and suction nozzles fixed therein, located concentrically in the housing of the rotor blade mounted on a vertical shaft, and made with the possibility of axial rotation of the deck, an energy source and rotor drive. The disadvantage of this device is the location and size of the windows in the deck, which can lead to clogging of their product peeling, and as a result - to reduce the effectiveness of peeling.

A device for peeling grain (patent for a utility model of the Russian Federation No. 128518/13, B02B 3/00), comprising a housing with loading, unloading and suction nozzles fixed in it, located concentrically in the housing of a rotor blade mounted on a vertical shaft, and made with the possibility of axial rotation of the deck, an energy source and rotor drive. Reversible deck is made in the form of a truncated cone, equipped with upper and lower covers. The top cover has a Central hole, the diameter of which is larger than the outer diameter of the loading nozzle. The angle of inclination of the side surface of the deck to the base is 50 ... 60 °. The diameter of the bottom cover connected to the side surface of the deck with four jumpers is equal to the diameter of the top cover. The disadvantage of this device is that the air flow created by the fan moves the grain not only in the direction of the deck outlet, but also under the blade rotor. As a result of this, part of the peeling product does not come out of the deck, but, unloading under the blade rotor, interferes with the peeling process.

The prototype of the utility model is a device for peeling grain of a pneumomechanical type (patent for utility model of the Russian Federation No. 2591725/13, B02B 3/00), containing a housing with loading, unloading and suction nozzles fixed in it, located in the housing of a rotor blade mounted on a vertical shaft , drive and reversing variator. The lateral surface of the rotating deck in the form of a truncated cone is made of a metal mesh, the diameters of the holes of which are smaller than the size of the equivalent grain diameter. The disadvantage of the prototype is that the mass of grain supplied for peeling into the loading nozzle interferes with air access to the working area of the rotor blade, which leads to a decrease in the intensity of grain movement along its blades and unloading, as well as to a lack of air flow for further grain movement in the device. The presence of the suction pipe in the prototype does not give the desired effect of supplying additional air, since it is fed into the exit zone of the air-grain mixture from the rotor blade.

An object of the invention is to increase the effectiveness of peeling.

The technical result is achieved in that in a device for peeling grain containing a housing with a discharge pipe fixed therein, a blade rotor mounted on a vertical shaft, a drive and a reversing variator located in the housing, and the side surface of the rotating deck in the form of a truncated cone is made of metal mesh, the hole diameters of which are smaller than the equivalent grain diameter, a receiving device is installed made in the form of an external pipe with a diameter of d, with an internal patter installed in it a diameter of d / 3 and connected to each other by jumpers. This design makes it possible to feed the processed product through the external pipe into the device for peeling grain, and air will flow unhindered into the device, into the working area of the rotor rotor, through the internal pipe.

The essence of the utility model is illustrated by the schemes shown in figures 1 and 2.

A device for peeling grain, contains a housing 1, with an unloading nozzle 3 fixed therein, a rotor 4 located in the housing, mounted on a vertical shaft 5, a drive 7 and a reversing variator 8, and the side surface of the rotating deck 6 in the form of a truncated cone is made of metal nets with hole diameters smaller than the equivalent grain diameter. The receiving device 2 mounted on the housing is made in the form of an external pipe 9 of diameter d, with an internal pipe 10 of diameter d / 3 installed in it and connected by jumpers.

A device for peeling grain works as follows. Grain is supplied through an external nozzle, while air freely enters the working area of the rotor blade through the internal nozzle. The resulting air-grain mixture is accelerated by a blade rotor, takes off from it and hits the side surface of a rotating deck in the form of a truncated cone. Peeling of the grain is carried out due to the impact of grain on the deck and the interaction between themselves in the air-grain mixture. Peeling products are removed from the device through the discharge pipe. The additional air flow entering through the inner pipe facilitates the intensive movement of the air-grain mixture in the device, the removal of peeling products from it, and is used to further separate them into fractions.

The use of this utility model allows to increase the efficiency of peeling grain.
