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 fan and duct, which are 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 perforated spring. The loading hopper is installed above the flat spring at its outer edge. A 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. The air duct is connected to the inner cavity of the casing from its opposite lateral sides.

In FIG. 1 shows a general view of the device, and in FIG. 2 is the same, a section along AA, in FIG. 3 - the same top view.

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, coaxially mounted inside the casing 1 can rotate the transporting working member 5, the heating element 6, and also a fan 7 and an air duct 8. The transporting working body 5 is made in the form of a flat perforated 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 plate 9 of a round shape. The heating element 6 is located under the transporting working body 5 and is made in the form of a flat ring. The unloading window 4 is installed coaxially to the casing 1 under the heating element 6. The duct 8 is connected to the inner cavity of the casing 1 from its opposite lateral sides.

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 surplus. The air flow created by the fan 7 passes through the duct 8, then through the perforation of the transporting working body 5 captures the vapor released from the grain of moisture and, leaving the device through the feed hopper 3 and the discharge window 4, removes it outside. By selecting the rotational speed of the transporting working body 5, the residence time of the grain in the device is established. Dry grain is removed from the device through the discharge window 4, which is installed coaxially to the casing 1 under the heating element 6.

The vertical arrangement of the installation casing, the implementation of the conveying working body in the form of a flat perforated spring, the installation of the hopper above the flat spring at its outer edge, the installation of a round plate rigidly connected to it and equipped with a drive, the location of the heating element under the conveying working body and execution it in the form of a flat ring, installing the discharge window coaxially to the casing under the heating element, as well as connecting the duct to the inner cavity w casing from opposite lateral sides thereof - all it increases the quality of grain drying and reduces energy costs.
