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, a transporting working member 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 contains a fan and duct connected to the inner cavity of the casing.

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

The technical result is an increase in the quality of drying grain.

The technical result is achieved by the fact that on the lateral surface of the turns of the screw parallel to its axis, rods are installed, which are guided towards the discharge window. The rods are arranged around the circumference at equal angles and at different distances from the screw shaft.

In FIG. 1 shows a General view of the device; in FIG. 2 - section along the line aa.

The device for drying grain consists of a cylindrical casing 1, covered with heat-insulating material 2, a loading hopper 3, an unloading window 4, mounted inside the casing 1 with the possibility of rotation of the transporting working body 5, made in the form of a screw, as well as heating elements 6 placed on the outer surface casing 1 under a layer of heat-insulating material 2. On the lateral surface of the turns of the screw parallel to its axis are rods 7, which are directed towards the discharge window 4. The rods 7 are arranged circumferentially through equal angles and at different distances from the screw shaft.

The device operates as follows. The heating elements 6 are turned on and the drive (not shown in FIG.) Of the transporting working member 5. After reaching the required temperature of the casing 1, grain is fed into the loading hopper 3. The grain is captured by a screw from the loading hopper 3 and, heating, moves it along the inner surface of the casing 1 to discharge window 4, losing moisture. During rotation, the auger pushes the grain toward the discharge window 4, and the rods 7, located around the circumference through equal angles and at different distances from the auger shaft, constantly mix the grain layers. Due to this, the uniformity of grain heating is increased and the possibility of overheating of individual grains is eliminated. Dry grain is removed from the device through the discharge window 4.

The installation of the rods on the lateral surface of the auger turns parallel to its axis, their direction towards the discharge window, the location of the rods around the circumference at equal angles and at different distances from the auger shaft - all this ensures high quality grain drying.
