Fan structure of grain drying machine, and grain drying machine

Abstract

The invention discloses a fan structure of a grain drying machine, and the grain drying machine. The fan structure comprises a heat insulation air pipe, a fan and a joint bearing, electric heating iron is arranged in the heat insulation air pipe and spirally arranged, the electric heating iron is tightly attached to the inner pipe wall of the heat insulation air pipe, the tail end of the heat insulation air pipe is fixedly connected with the fan, a duckbilled spray head is arranged at the other end of the heat insulation air pipe, the electric heating iron is fixedly connected with the heat insulation air pipe, a heat exchange pipe is arranged in the heat insulation air pipe and inserted into an area wound by the electric heating iron, a heat conduction rod is arranged between the heat exchange pipe and the electric heating iron, the two ends of the heat conduction rod are welded to the heat exchange pipe and the electric heating iron correspondingly, the heat exchange pipe is suspended in the area wound by the electric heating iron through the heat conduction rod, a punched hole is formed in the heat exchange pipe, and the heat insulation air pipe penetrates through the joint bearing and is fixedly connected with the joint bearing. The fan structure of the grain drying machine is good in blowing angle adjustability.

Description

technical field [0001] The invention relates to a fan structure of a grain drying machine and the grain drying machine. Background technique [0002] When the grain dryer is working, the motor drives the impeller of the axial flow fan to rotate at a high speed, so that the hot air generated by the combustion of the coal furnace is sucked into the fan through the upper part of the baffle plate, and forms a mixture with the cold air sucked into the fan from the lower part of the baffle plate, and passes through the windshield pipe After entering the stacking rack, it diffuses. When the mixed gas passes through the grain layer on the stacking rack, the temperature of the millet is increased appropriately, and a large amount of water vapor is taken away to gradually dry the millet. [0003] However, the blowing angle of the fan of the current grain dryer cannot be adjusted, and the flexibility is average, so it is necessary to improve it. Contents of the invention [0004] Th...
