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 comprises 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 disadvantages of uneven grain drying and high energy costs for drying.

The technical result achieved using the utility model is to increase the quality of grain drying and reduce energy costs for drying.

The specified technical result is achieved by the fact that the casing is positioned vertically. The transporting working body is made in the form of a flat spring. The loading hopper is installed above the flat spring at its outer edge. A perforated round plate is rigidly connected to it and equipped with a drive and mounted on a flat spring. The heating element is located under the transporting working body and is made in the form of a flat ring. The unloading window is installed coaxially to the casing under the heating element.

In FIG. 1 shows a general view of the device, and in FIG. 2 - the same, a section along AA.

The device for drying grain includes a vertically arranged casing 1, made in the form of a cylinder, the outer surface of which is covered with a layer of heat-insulating material 2, a loading hopper 3, an unloading window 4, a transporting working element 5 coaxially mounted inside the casing, and a heating element 6. The transporting working body 5 is made in the form of a flat spring. The loading hopper 3 is mounted above a flat spring at its outer edge. On a flat spring is installed rigidly connected with it and equipped with a drive perforated plate 7 of a circular shape. The heating element 6 is located under the transporting working body 5 and is made in the form of a flat ring. The discharge window 3 is installed coaxially to the casing 1 under the heating element 6.

The device operates as follows. Turn on the heating element 6 and the drive (not shown in Fig.), Which begins to rotate the perforated plate 7 of a round shape, and with it the transporting working member 5. After the surface of the heating element 6 reaches the required temperature, the grain is fed into the loading hopper 3. Grain poured from the loading hopper 3 is captured by an external turn of the transporting working body 5 and then moves along the turns of the transporting working body 5 to the discharge window 4. Contacting with the surface of the heater The leg member 6, the grain is heated and loses moisture excess which is removed as a vapor from the housing 1 through a perforated plate 7. By selecting the rotational speed of the conveying working member 5 mounted grain residence time in the apparatus. Dry grain is removed from the device through the discharge window 4. When using grain of a different culture, the temperature of the heating element 6 is changed, and the rotation frequency of the working body 5 is also changed.

The vertical arrangement of the casing, the execution of the transporting working body in the form of a flat spring, the installation of the loading hopper over the flat spring at its outer edge, the installation of the perforated round plate on the flat spring and equipped with a drive, the location of the heating element under the transporting working body and its implementation in the form of a flat ring, installing an unloading window coaxially to the casing under the heating element - all this improves the quality of grain drying and reduces costs Rats of energy.
