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 multiple spring 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.

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 multiple spring 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 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 multi-pass turns of the transporting working body 5 and then moves along the turns of the transporting working body 5 to the unloading window 4. Implementation of the transporting the working body in the form of a multi-start flat spring makes it possible to provide each grain with a strictly defined residence time during its rotation, which improves the quality of its drying, eliminating the possibility of overheating of the grains. Contacting with the surface of the heating element 6, the grain also heats up, loses excess moisture, which is removed in the form of steam from the casing 1 through the perforated plate 7. Dry grain is removed from the device through the discharge window 4. When using another crop grain, the temperature of the heating element 6 is changed, and also change the frequency of rotation of the working body 5.

The vertical arrangement of the casing, the implementation of the transporting working body in the form of a multiple spring flat spring, the installation of the hopper above the flat spring at its outer edge, the installation of a perforated round plate rigidly connected to it and equipped with a drive on a flat spring, the location of the heating element under the transporting working body and execution it in the form of a flat ring - all this improves the quality of grain drying and reduces energy costs.
