Multi-channel dumping grain drying machine

Abstract

The invention discloses a multi-channel dumping grain drying machine. The technical points include that: the lower part of the drying machine is a parallel dumping channel (9) composed of a tetrahedron inverse cone, a multi-channel dumping mechanism (11) is arranged on an elastic support (12), the aggregate bin (14) of the multi-channel dumping mechanism (11) is internally and uniformly provided with support frames (16), the mounting dip angle of the support frame (16) and the horizontal plane is 15-25 degrees. The support frame (16) is provided with metering blocks (10) with the same quantity of that of dumping channels; a distance of 10-50mm is kept between the metering block (10) and the dumping channel port (19) of the parallel dumping channel (9); a levelling grid (2) at the upper part of the drying machine is hung on an elastic hanger (3), the lower end of a guiding rod (4) is connected with a guiding rod support (25) on the metering block (10), the guiding rod (4) penetrates a drying chamber (6) upward from the dumping channel port (19) of the parallel dumping channel (9) of the drying machine, and the guiding rod (4) is connected with the levelling grid (2) at the top of the drying machine. The invention has the advantages that structure is simple, motion of material in the machine is uniform, material drying precipitation is uniform and drying speed is high, and drying quality of material can be fully maintained.

Description

technical field [0001] The invention belongs to the field of material drying technical equipment, in particular to grain drying technical equipment, in particular to a multi-channel discharging grain dryer. Background technique [0002] At present, there are two types of grain drying technology equipment at home and abroad: continuous type and intermittent type. The grain drying method is mainly convection drying. More than 95% of grain dryers use hot air as the drying medium. Regardless of whether it is a continuous or intermittent grain dryer, the movement of grain in the dryer depends on the gravity of the grain itself, moving from top to bottom. In the grain dryer with hot air as the drying medium, there are angular boxes or mesh boxes for the drying medium to enter the dryer and flow out of the dryer. These angular boxes or mesh boxes are fixed. It will produce various resistances to the movement of the grain in the dryer, resulting in uneven movement of the grain in t...

Problems solved by technology

When the grain is harvested in rainy weather, its moisture content and impurity content will be high, the fluidity of the grain is poor, and it is easy to form arches and bridges in the dryer, which seriously affects the drying quality and production efficiency.
