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 unloading 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 throughput of drying grain.

The objective of the utility model is to increase the throughput of the grain drying process.

The technical result is achieved due to the fact that the device for drying grain is multi-sectional. Moreover, the sections are mounted on the frame parallel to each other in the horizontal plane. The loading hopper is connected to the loading window by each section. The unloading window of each section is located above the unloading hopper. The duct is connected to the discharge hopper.

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

The device for drying grain contains sections, each of which includes a cylindrical casing 1, the outer surface of which is covered with a layer of heat-insulating material 2, a loading hopper 3, an unloading hopper 4, coaxially mounted inside the casing rotatably transporting the working body 5, made in the form of a screw . On the outer surface of the casing 1 under the layer of heat-insulating material 2 between the loading hopper 3 and the discharge hopper 4 there are heating elements 6. The device for drying grain also includes a fan 7 and an air duct 8. The sections are mounted on the frame 9 and are parallel to each other in a horizontal plane . The loading hopper 3 is connected to the loading window by each section. The discharge window of each section is located above the discharge hopper 4.

The device operates as follows. Turn on the heating elements 6 of each section of the device. After reaching the required temperature of the casings 1, the grain is fed into the loading hopper 3 of the upper section, from where it enters the transporting working body 5 and moves by it to the discharge window of each section. At the same time turn on the fan 7. In contact with the heated surface of the casing 1, the grain also heats up, loses excess moisture. The fan 7 supplies the air flow through the duct 8 to the discharge hopper 4, while cooling the grain and removing moisture from it in the form of steam through the discharge hopper 4. The cooled and dried grain is removed through the discharge hopper 4.

The implementation of the device is multi-sectional, placing the sections on the frame and placing them parallel to each other in a horizontal plane, connecting the loading hopper to each section, positioning the discharge window of each section above the discharge hopper, connecting the duct to the discharge hopper increases the throughput of the device.
