Description

The invention relates to the processing industries of agricultural production, in particular to devices for washing and removing external moisture from grain, for example, before grinding.

A device for removing external moisture from grain [1], containing a housing, a rotor, a sediment collector and a spiral. The rotor is made in the form of a perforated drum resting on rollers. The spiral is located in the lower part of the rotor parallel to its axis with the possibility of rotation. A rod is installed inside the spiral. The rotor and spiral are equipped with a drive with the ability to independently change the frequency of their rotation.

The known device has disadvantages, which include the impossibility of combining the technological processes of washing and smoothing grain in it and the insufficient quality of removing external moisture from the grain.

The purpose of the invention is to improve the quality of the process of removing external moisture from the grain and increase the manufacturability of the device.

The goal is achieved by the fact that the housing is mounted on racks adjustable in height with the possibility of fixing its position, a centrifugal nozzle is installed inside the rotor. The spiral is connected to the shaft with spokes radially and evenly installed inside it and installed with the possibility of changing the gap between its outer surface and the inner surface of the rotor and fixing it in the desired position.

Figure 1 shows a General view of the device for washing and smoothing grain, figure 2 is a section along aa.

A device for washing and smoothing grain consists of a housing 1, a rotor 2, made in the form of a perforated drum, supported on rollers 3 from each end and rotationally driven by a drive 4, a loading chute 5, a sediment collector 6, a spiral 7 with a rod 8 , a collection of dry grain 9. The housing 1 is mounted on height-adjustable uprights 10 with the possibility of fixing its position by means of stoppers 11. A centrifugal nozzle 12 is installed inside the rotor 2. Spiral 7 is installed with the possibility of changing the gap between its outer surface and the inner surface of the rotor 2 and is connected to the rod 8 by spokes 13, which are installed radially and evenly inside it.

A device for washing and smoothing grain works as follows. The grain is fed through the loading chute 5 into the inner cavity of the rotor 2, which receives rotation from the drive 4. At the same time, the grain is treated with water supplied to it under pressure through a centrifugal nozzle 12, which is installed inside the rotor 2. The centrifugal force arising from the rotation of the rotor 2 presses the grain to the wall of the rotor 2. Moisture from the surface of the grain, along with impurities, leaves through the perforation into the internal cavity of the housing 1 and flows through the sediment collector 6. By rotating spiral 7, the grain is evenly distributed along the inner surface the surface of the rotor 2 and gradually moves axially along the inner surface of the rotor to the dry grain collector 9. The rod 8 connected to the spiral by the spokes 13 radially and evenly mounted inside it does not allow the spiral 7 to stretch and deflect in the direction of rotation of the rotor 2 due to friction forces , ensuring uniformity of unloading of the finished product in the collection of dry grain 9.

The capacity of the device and the moisture content of the grain at the exit from it are regulated by an independent change in the frequency of rotation of the spiral 7 and (or) the frequency of rotation of the rotor 2, by changing the gap between the outer surface of the spiral 7 and the inner surface of the rotor 2, and also by changing the location of the housing 1 with respect to the horizontal using height-adjustable racks 10 and fixing the housing 1 in the required position by the stops 11.

To improve the quality of washing and smoothing grain, the housing 1 is lifted from the collector of dry grain 9, and from the side of the loading chute 5 is lowered. In this case, the rotational speed of the rotor 2 is increased, and the spiral 7 is reduced. In the case of washing and smoothing grain of other crops with different dimensional characteristics, the gap between the outer surface of the spiral 7 and the inner surface of the rotor 2 is changed, and then the spiral 7 is fixed in the desired position.

This device makes it possible to simultaneously wash the grain and remove external moisture from its surface along with contaminants, allowing you to adjust the degree of efficiency of this process when using grain from various crops.

The connection of the spiral with the rod with knitting needles that are installed radially and evenly inside it ensures a constant gap between the spiral and the rotor and the friction forces that arise during operation. This improves the uniformity of grain unloading and, as a result, the quality of removal of external moisture from the grain.
