Description

The invention relates to a device for peeling grain barley, pea and wheat and can be used in large feed mills and flour mills.

The aim of the invention is to increase the efficiency of the operation of the listening staff.

The proposed machine design allows you to adjust the size of the working gap, and therefore, the intensity of the impact of the working bodies of the machine on the processed grain. The need for such regulation is not only in the transition from the processing of one type of raw material to another, and not in the process of shelling the same material, which is characterized by variable physical properties, size, humidity, fullness, etc. In addition, regulation of radial Oog of the gap in the process It is possible to compensate for the change in the roughness of the abrasive and steel surfaces of the working parts of the machine, while maintaining the technological efficiency of peeling at a high level. In particular, the peeling ratio can be increased by an average of 3-5%, and the fragmentation of the core is reduced by 1-2%.

FIG. Figure 1 shows the functional-kinematic diagram of the peeling machine; in fig. 2 - abrasive bar, cut.

The machine includes a housing 1, a suction inlet 2, a vertical shaft 3, a stationary sieve cylinder 4 enclosing it, an outlet nozzle 5 for peeling products, a suction nozzle 6 for sucking air with lightly and finely salvaging products and a drive shaft 3 (conventionally not but shown). On the shaft 3 there are radially installed abrasive bars 7, which are evenly spaced but formed, with its cylinder and rigidly fixed in the holders 8, installed with the possibility of radial mixing and associated with the gap adjustment mechanism between the abrasive surface and the perforated cylinder 4, made in the form of a pipe 9 with a thread on the outer surface connected with the drive 10 of vospodatelnogo movement and located coaxially to the shaft 3-, while on the pipe 9 mounted nuts 11, pivotally connected with the holders 8. Bars 7 hang trap The esidal shape with a large base 12 is oriented to the axis of the shaft 3, and the smaller base 13 is visible, 1 is not curvilinear. A left-handed thread is mounted on one of the nuts 11 and on the corresponding section of pipe 9.

Shelling machine works as follows.

The original grain material enters the machine through the inlet pipe 2 and under the action of centrifugal inertial forces.

arising during the rotation of the shaft 3, enters the inner surface of the sieve cylinder 4, along which it slides, describing the spiral trajectory and gradually approaching the outlet nozzle 5 in the lower part of the machine. In this way, the grain is peeled off intensively due to friction on the abrasive surface of the bars 7 and the steel surface of the core} of the core 4. 4. Small and aerodynamically light particles formed during the grain baking process pass through the sieve holes and together with the dusty air are sucked out of the machine through Other nozzle 6. Peeled grain mixed with other large peeling products leaves the main pipe through the outlet nozzle 5. Taking samples of peeling products and subjecting them to standard analysis, determine the effectiveness indicators - peeling coefficient and the content in the peeling products of shotgun grains. The number of these indicators determines the need for adjusting the size of the worker, the gap, i.e., the radial gap between the end surface of the abrasive bars 7 and the inner surface of the sieve steel cylinder 4. The gap is adjusted after the complete stop of the mat. To do this, stop the supply of the original grain and after emptying the internal space of the drop, stop the drive motor. With the gearbox drive 10, a pipe 9 is inserted, along which the nuts 11 are mixed in opposite directions. In this case, radial translational movement of the bars occurs: towards the center, which increases the working clearance, either from

center, which reduces the working gap. After adjustment, MaiHHHy include in the work.

The invention makes it possible to increase the efficiency of the action of the maple in order to optimize the process of bluing due to the regulation of the size of the working gap. At this m., It is possible to achieve high values of the peeling coefficient with a simultaneous restriction of the crushing of der.
