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 2411432. - Publ. 02/10/2011, Bull. No. 4], containing a rectangular casing, the surface of which is covered with a layer of heat-insulating material, a loading hopper, an unloading window, heating elements located between the loading hopper and the unloading window, as well as a fan and duct. A transporting working element is installed inside the casing, made in the form of an endless chain with scrapers, also a plate is horizontally installed inside the casing, on the lower side of which there are heating elements, and the upper branch of the chain with scrapers rests on the plate. The air duct is connected to the casing at an equal distance from the loading hopper and the discharge window.

The known device has the disadvantage of uneven drying of grain.

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

The specified technical result is achieved by the fact that the transporting working body is performed in the form of a box, which is mounted pivotally and is equipped with a vibrodrive. The upper surface of the box is ribbed and perforated. The ribs are placed across the box and perform undulating. The size of the perforations is performed not exceeding the minimum grain size. The duct is connected to the inner cavity of the duct. Heating elements are installed in the duct.

In FIG. 1 shows a General view of the device; in FIG. 2 - the same, a section along AA.

The device for drying grain includes a casing 1 of rectangular cross-section, the surface of which is covered with a layer of heat-insulating material 2, a loading hopper 3, an unloading window 4, heating elements 5, a fan 6, an air duct 7, a transporting working body installed inside the casing 8. Transporting working body 8 made in the form of a box, which is mounted on hinges 9 and is equipped with a vibratory drive 10. The upper surface of the box is ribbed and perforated. The ribs are located across the box and made wavy. The size of the perforations is performed not exceeding the minimum grain size. The duct 7 is connected to the inner cavity of the duct. Heating elements 5 are installed in the duct 7.

The device operates as follows. Turn on the fan 6. At the same time, turn on the heating elements 5. The air flow generated by the fan 6, heated by the heating elements 5, through the air duct 7 enters the transporting working body 8, and then through the perforated upper surface of the box goes inside the casing 1. After reaching the required temperature of the air the flow include a vibrating actuator 10 of the transporting working body 8. The transporting working body 8 due to the installation on the hinges 9 begins to make oscillatory movements I am. Then wet grain is fed into the loading hopper 3, from where it enters the upper surface of the box, which is made ribbed and perforated, the ribs being located across the box and made wavy, and the size of the perforations made not exceeding the minimum grain size. Due to the oscillatory movement, the transporting working body 8 moves the grain to the unloading window 4. The implementation of the ribs of a wave-like shape and their arrangement across the box ensures uniform grain intake from the loading hopper 3 and its distribution along the width of the box. Due to the size of the perforations of the upper surface of the box not exceeding the minimum grain size, the grain does not fall into the box, and during the movement to the discharge window 4, the grain is uniformly blown by the heated air flow created by the fan 6. In contact with the heated air flow, the grain also heats up, loses excess moisture, which in the form of steam is removed from the device by air flow through the discharge window 4. Dry grain is also removed from the device through the discharge window 4.

Performing a transporting working body in the form of a box that is hinged and equipped with a vibrodrive, making the top surface of the box ribbed and perforated, arranging the ribs across the box and making them wavy, making the size of perforations not exceeding the minimum grain size, connecting the duct to the internal cavity of the box, installing heating elements in the duct - all this improves the quality of grain drying.
