UA69959A - Machine for grain polishing - Google Patents

Abstract

Machine for grinding of grain contains housing, placed in it and connected with the drive vertical perforated shaft with rigidly fixed on it grinding wheels, between which are mounted guiding cones, loading and unloading branch connections, aspiration branch connection. In this case, each second grinding wheel is connected with perforated shaft with the help of the planetary gear with possibility of rotation in the direction opposite to the direction of rotation of other disks.

Description

Description of the invention

The invention relates to the technology of flour milling and grain production, to machines for grinding 2 filmy grain grains, mainly barley, in the production of grains, compound feed, grain preparation for grinding, and can be used in grain and compound feed factories, mills, in agriculture.

A well-known machine for peeling and grinding grains of cereal crops and fodder grain, which contains horizontal abrasive disks placed in the body on a vertical shaft, surrounded by a sieve cylinder. Guide cones are installed between the disks, on the inner and outer surfaces of which guides are fixed. 70 Guides are inclined relative to the surface of the disks in the direction of their rotation to the angle of friction of the grain against the material of the guides (5И0Мо1761258А1, VO283/02, 15.09.92 Byul. Moz4).

The disadvantage of this machine is the low efficiency of grinding, due to insufficiently intensive action of the abrasive discs on the grain.

The invention aims to increase the efficiency of grain grinding. The task set by the invention 72 is achieved by the fact that the machine for grinding grain contains a housing, placed in it and connected to the drive, a vertical perforated shaft with rigidly fixed abrasive discs on it, between which guide cones are installed, which is fixed on a sieve cylinder placed in the housing concentric shaft with disks, loading and discharge nozzles, located respectively in the upper and lower parts of the body, aspiration nozzle, according to the invention, every second abrasive disk is connected to a perforated shaft using a planetary gear with the possibility of rotation in the direction opposite to the other disks.

One of the variants of the grain grinding machine is shown schematically in Fig. 1. The grain grinding machine includes a housing 1, a loading 2 and an outlet From the nozzle, valve 4 of the outlet nozzle 3, placed in the housing 1 and connected to the drive 5 is a vertical perforated hollow shaft 6 with rigidly fixed abrasive discs 7, discs 8, with connected to the shaft 6 by means of a planetary gear 29 transmission, which consists of a crown gear 9, satellite gears 10, fixed on guides 11, a central gear 12 and protective covers 13 and 14 preventing the product from entering the gear, a sieve cylinder 15, an aspiration nozzle 16.

The machine works like this. The grain material enters the space between the sieve cylinder 15 and the movable abrasive discs 7, 8, which rotate in opposite directions, through the loading nozzle 2 along the guides 11. At the same time, the grain rubs against each other, along the surface and over the entire working surface of the movable abrasive discs. Thanks to the rotation of adjacent abrasive discs in opposite directions, the grain is actively mixed in the working space between the discs, subjected to more intensive friction against their surfaces without being dragged into the rotational movement between them. Protective casings 13 and 14 prevent the grain from entering the planetary gearing of the discs 8. When the grain moves to the outlet nozzle 3, the shells are separated, the bulk of which is removed from the working area of the machine by air entering through the holes of the hollow vertical shaft 6 and with the grain , which enters for processing, through nozzle 16 into the aspiration system. The polished grain is discharged through outlet nozzle 3. The technological efficiency of the grinding process is regulated by the amount of product coming out of the machine with the help of valve 4 located in outlet nozzle 3.

The use of abrasive discs rotating in different directions in the machine for grinding significantly increases the intensity of grain friction in the working area of the machine and allows you to significantly increase the efficiency of grinding. :z" ! : nd gi ni shi ya" Shen Noni
