Description

The utility model relates to agricultural machinery, in particular, to devices for drying grain.

A device for drying grain [Device for drying grain. - Patent RU 2323580. - Publ. 05/10/2008, Bull. No. 13], comprising a cylindrical casing, a loading hopper, an unloading window, transporting a working body coaxially mounted inside the casing with the possibility of rotation, as well as heating elements. The outer surface of the casing is covered with a layer of heat-insulating material. The transporting working body is made in the form of a screw with perforated turns, the diameter of the perforation does not exceed the minimum grain size. The casing is made integral, and its components are divided among themselves by rings made of heat-insulating material. Heating elements are placed on the outer surface of the casing under a layer of heat-insulating material between the loading hopper and the discharge window with the possibility of individually controlling the heating temperature of each of the sections of the casing. Each component of the casing is equipped with an individual heating element, and the end surface of the casing from the side of the loading hopper is perforated. In addition, the device includes a cooling device, which consists of a fan and an air duct connected to the inner cavity of the casing behind the discharge window.

The known device has the disadvantage of low quality grain drying.

The objective of the utility model is to improve the quality of grain drying.

The technical result is achieved due to the fact that the device for drying the grain is performed composite with an even number of components. Odd parts of the casing contain heating elements and are coated with a layer of heat-insulating material. In even parts of the casing in the upper and lower zones of the surfaces of the casing, holes are made whose size does not exceed the minimum grain size. The even parts of the casing are connected from the bottom by an air duct to the fan.

In FIG. 1 shows a General view of the device.

The device for drying grain consists of a cylindrical casing 1, a hopper 2, an unloading window 3, coaxially mounted inside the casing 1 with the possibility of rotation of the transporting working body 4, made in the form of a screw, the casing 1 is made integral with an even number of components, and the odd parts of the casing 1 contain heating elements 5 and are covered with a layer of heat-insulating material 6, and holes are made in even parts of the casing 1 in the upper and lower zones of the surfaces of the casing 1, the size of which does not exceed the minimum Dimensions of grain, and even components of the housing 1 on the lower side connect the duct 7 with a fan 8.

The device operates as follows. Turn on the heating elements 5 in the odd constituent parts of the casing 1. After reaching the required temperature of the odd constituent parts of the casing 1, the grain is fed into the feed hopper 2, from where it is transported by the transporting working body 4 to the discharge window 3. At the same time, the fan 8 is turned on. Contacting the heated surface in the odd component parts of the casing 1, the grain also heats up and loses excess moisture. Next, the transporting working body 4, the grain moves along the even component parts of the casing 1. The fan 8 supplies the air flow through the duct 7 through the lower zone of the even component parts of the casing 1 uniformly blowing and cooling the grain. In this case, moisture is removed from the grain in the form of steam through openings in the upper zones of the even component parts of the casing 1. Dried and cooled grain is removed from the device through the discharge window 3.

The implementation of the device composite with an even number of components, the placement on the odd parts of the casing of the heating elements and coating them with a layer of insulating material, the execution in even parts of the casing in the upper and lower zones of the surfaces of the casing of the holes, the size of which does not exceed the minimum grain size, as well as the connection of even composite parts of the casing on the underside with an air duct with a fan - all this provides an increase in the quality of grain drying.
