Abstract

PURPOSE:To prevent drying shortage and over-drying and to properly dry grain within the preset drying time by constituting a grain dryer equipped with an inclined vent floor for passing hot wind so that grain is allowed to naturally flow on the vent floor and the layer thickness of grain is made changeable. CONSTITUTION:In a grain dryer equipped with an inclined vent floor 82 for passing hot wind, the layer thickness L of grain allowed to naturally flow on the vent floor 82 is made changeable by a controlling plate 126 of the layer thickness of grain. In other words, in the case of grain plenty in moisture content, the layer thickness L of grain is made thin. In the case of grain low in moisture content, the layer thickness L of grain is made thick. Thereby drying shortage and over-drying are prevented and grain is properly dried within the preset drying time.

In addition, both ends of the spindle (83a) of each impeller (83) disposed above one louver bed (82) are connected to the guide hole (11).
3) so as to be movable up and down, and both ends of the support shaft (83a) are integrally connected via a link (114), and the electric motor (115) (116) or the operating lever (117) (11
Drive gear (119) (120) rotated by
Rack gear arms (121) and (122) are integrally formed on both ends of the link (114), and each impeller (83) is provided so as to be movable toward and away from the louver bed (82). ) above the sloped upper end side of
A grain layer thickness adjusting plate (126) is provided via an automatic fulcrum shaft (125) rotated by an electric motor (123) or an operating lever (124), and the adjusting plate (125) is provided on the side of the inclined upper end of the louver bed (82). ) by expanding or reducing the gap (127) with the adjusting plate (126) to adjust the amount of grain flowing onto each louver bed (82) and adjust the grain layer thickness (L) on each louver bed (82). can be changed, and the grain layer thickness (L) is made thinner for grains with a high water content, while the grain layer thickness (L) is made thicker for grains with a low water content.

"Effects of the Invention" As is clear from the above embodiments, the present invention provides an apparatus equipped with an inclined aeration bed (82) for passing hot air, in which a grain layer of grain is allowed to flow down by gravity on the aeration bed (82). Thickness (L
) is configured so that the grain layer thickness (L) can be changed in the case of grains with a high moisture content, and the grain layer thickness (L) can be increased in the case of grains with a low moisture content. This has the remarkable effect of preventing insufficient drying and over-drying, and allowing grain to be properly dried within a preset drying time.
