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 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. A perforated round plate is rigidly connected to it and equipped with a drive and mounted on a flat spring. The heating element is placed under the transporting working body and perform it in the form of a flat perforated ring. The size of the holes of a flat perforated ring is performed not exceeding the minimum grain size. The duct is connected from the bottom to the heating element.

In FIG. 1 shows a general view of the device, and in FIG. 2 - the same 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, coaxially mounted inside the casing rotatably transporting the working body 5, the heating element 6, and fan 7 and air duct 8. The transporting working body 5 is made in the form of a flat spring. On a flat spring is installed rigidly connected with it and equipped with a drive perforated 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 perforated ring. The hole size of a flat perforated ring does not exceed the minimum grain size. The duct 8 is connected from the bottom to the heating element 6.

The device operates as follows. Turn on the heating element 6 and the drive (not shown in Fig.), Which starts to rotate the perforated plate 9 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 a coil of the transporting working body 5 and then moves by turns of the transporting working body 5 along the perforated surface of the flat ring to the discharge window 4. ak as the size of the holes perforated flat rings does not exceed the minimum grain size, it does not permit the grain to fall down through them. Contacting with the surface of the heating element 6, the grain also heats up, loses excess moisture. The air flow created by the fan 7 passes through the duct 8, then through the perforation of the heating element 6 and, leaving the device through the perforation of the plate 9, removes moisture evaporated from the grain. Dry grain is removed from the device through the discharge window 4.

The vertical arrangement of the casing, the implementation of the conveying working body in the form of a flat spring, 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 conveying working body and its execution in the form of a flat perforated ring, making holes of a flat perforated ring size not exceeding the minimum grain size, the connection of the duct from the bottom to the heating element - all this improves the quality of grain drying and reduces energy costs.
