Grain dryer which can improve drying efficiency

Abstract

The invention relates to a grain dryer which can improve the drying efficiency. The grain dryer comprises a main body, a winnowing mechanism, a conveying mechanism, a heating mechanism and a material guide mechanism, wherein the winnowing mechanism comprises a first motor, a first support plate, a limiting block, a second support plate, a spring, a support rod and a scattering plate; the conveying mechanism comprises a first conveyor and a second conveyor; the heating mechanism comprises a hot-air blower, a rotation shaft, a bearing, a worm gear, a worm and a second motor; the material guide mechanism comprises a connecting plate, a first baffle plate, a second baffle plate, a second spring and a third spring. Grains are added to the second conveyor, then are sent to the scattering plate through the conveying mechanism, and finally are winnowed down from scattering holes through up and down vibration of the scattering plate, and therefore the uniform dropping out of the winnowed grains is realized. Meanwhile, hot air is blown out from hot air holes and the rotation shaft rotates, therefore the grains are uniformly heated in the falling process. The grains can be guided into the second conveyor again through the material guide mechanism to realize circular drying, and therefore the drying efficiency is improved.

Description

technical field [0001] The invention relates to the field of dryers, in particular to a grain dryer with improved drying efficiency. Background technique [0002] After the grain is harvested, it needs to be dried before it can be stored. The traditional grain drying method is to lay the grain on the open ground and dry it in the sun. In addition, if the weather is cloudy and rainy, it will not be able to dry in time, which will cause the food to become moldy and deteriorate due to moisture. In order to solve this problem, people have invented a dryer, so the food can be dried even in rainy weather. , and compared with the sun drying method, the speed is faster, but there are still some shortcomings in the current dryer, for example, the drying is not uniform enough, there are dead angles, and the drying efficiency is relatively low. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a grain dryer with improved dry...

[0002] After the grain is harvested, it needs to be dried before it can be stored. The traditional grain drying method is to lay the grain on the open ground and dry it in the sun. In addition, if the weather is cloudy and rainy, it will not be able to dry in time, which will cause the food to become moldy and deteriorate due to moisture. In order to solve this problem, people have invented a dryer, so the food can be dried even in rainy weather. , and compared with the way of drying in the sun, the speed is faster, but there are still some shortcomings in the current dryer, for example, the drying is not uniform enough, there are dead angles, and the drying efficiency is relatively low
