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 174687. - Publ. 10/26/2017, Bull. No. 30] comprising a rectangular casing, the surface of which is covered with a layer of heat-insulating material, a loading hopper, an unloading window, heating elements, a fan, an air duct, as well as a transporting working element installed inside the casing. The transporting working body is made in the form of a box and is installed with the possibility of informing him of vibrations. The upper surface of the box is made stepped from heat-conducting material. Holes are made on the side surfaces of the steps. Heaters are installed on the underside of the steps. The duct is connected to the inner cavity of the duct. Heating elements are installed in the duct.

The known device has the disadvantage of low quality drying.

The technical result achieved by using the utility model is improving the quality of grain drying.

The technical result is achieved by the fact that the transporting working body is made in the form of a tray of heat-conducting material, which is mounted on elastic elements with the possibility of communicating vibrations to it. In the lower part of the casing, from the side opposite the feed hopper, a cooling column with perforated plates inside it is installed. An unloading window is installed in the lower part of the cooling column. The duct is installed at the bottom of the cooling column. The lower part of the wall of the discharge window located in the cooling column and the upper part of the casing above the cooling column are perforated.

In FIG. 1 shows a general view of the device, FIG. 2 - section of the working body along the line AA.

The device for drying grain includes a casing 1, the surface of which is covered with a layer of heat-insulating material 2, a loading hopper 3, an unloading window 4, a heating element 5, a fan 6, an air duct 7 and a transporting working body 8 installed inside the casing 1. The transporting working body 8 is made in the form tray of heat-conducting material, which is mounted on elastic elements 9 with the possibility of message to him vibrations, which excites a vibrator 10 rigidly connected to the transporting working body 8. In the lower part of the casing 1 from the side opposite to the feed hopper 3, a cooling column 11 with perforated plates 12 inside it is installed. The discharge window 4 is installed in the lower part of the cooling column 11. The duct 7 is installed below the cooling column 11. The lower part of the wall of the discharge window 4, located in the cooling column 11, and the upper part of the casing 1 above the cooling column 11 are perforated.

The device operates as follows. Turn on the heating element 5. After reaching the required temperature of the upper surface of the transporting working body 8, turn on the vibrator 10. The transporting working body 8, mounted on the elastic elements 9, begins to vibrate. The wet grain is fed into the loading hopper 3, from where it enters the vibrating transporting working body 8 and moves along it to the cooling column 11. Contacting with the heated surface of the transporting working body 8, the grain heats up, losing excess moisture. Then the grain enters the cooling column 11. Moving along the perforated plates 12 of the cooling column 11, the grain, slowing down its speed, loses moisture when it is cooled by the air flow created by the fan 6. The air flow passes through the grain moving in the cooling column 11 between the perforated plates 12, and then through the upper perforated part of the casing 1, moistened air is removed to the outside. After passing through the cooling column 11, the grain is removed from the device through the discharge window 4.

When using grain of another culture, the heating temperature of the transporting working body 8 is changed using heating elements 5, the frequency and (or) the amplitude of the vibrations transmitted by the vibrator 10 to the transporting working body 8 are changed, as well as the speed of the air flow supplied by the fan 6 through the air duct 7 to the cooling column eleven.

The implementation of the transporting working body in the form of a tray of heat-conducting material mounted on elastic elements with the possibility of message to him vibrations, the location of the cooling column with perforated plates inside in the lower part of the casing from the side opposite the loading hopper, the installation of the discharge window in the lower part of the cooling column with the location of the duct bottom of the cooling column, as well as the implementation of the lower part of the wall of the discharge window, located in the cooling column and the upper Asti casing over perforated cooling column enables uniform heating and cooling of the grains in the apparatus, improving the quality of night. In this case, the dried grain, moved by a vibrating transporting working body to the cooling column, constantly turns around its axis under the influence of vibration. After heat exposure, the grain temperature decreases in the cooling column, which increases the loss of moisture from the grain surface, also improving the drying quality.
