Grain falling mechanism for grain drying machine

Abstract

The invention discloses a grain falling mechanism for a grain drying machine. The grain falling mechanism comprises a grain falling hopper and an adjusting assembly. A U-shaped seat is arranged in the middle of the left side face of the grain falling hopper, a driving belt wheel is rotationally connected into the U-shaped seat through a bearing, and a motor output shaft arranged at the left side face of the U-shaped seat is fixedly connected with the left end of the driving belt wheel; and the adjusting assembly comprises a driving unit and a flow adjusting unit, the driving unit and the flow adjusting unit are both arranged in the grain falling hopper, the driving unit is in transmission connection with the driving belt wheel, and the flow adjusting unit is rotationally connected with the driving unit through a pin shaft, wherein a control switch is arranged on the front side face of the grain falling hopper, and the input end of the control switch is electrically connected with an external power source. According to the adjustable grain falling mechanism for the grain drying machine, the horizontal blocking area of a material blocking plate on the grain falling hopper can be changed, so that the falling flow of grains in unit time is changed, and the grain falling work at different flow speeds is met.

Description

technical field [0001] The invention relates to the technical field of grain processing equipment, in particular to a grain dropping mechanism for a grain dryer. Background technique [0002] Grain refers to the general term of various plant seeds in cooking food, and can also be generally referred to as "grain". Grain is mainly divided into wheat, beans, rice and coarse grains, and also includes pumpkin, cucumber, cassava, sweet potato, potato, cabbage and spinach as supplementary staple foods such as fruits and vegetables. [0003] In the process of grain processing, it is necessary to use a grain dryer to process the grain. The grain dryer can generate a large amount of hot air in a short time, kill insect eggs through high-temperature treatment, and completely solve the problem of grain drying. When the grain dryer is drying, it usually uses manual filling to send the grain into the inside of the grain dryer for drying. [0004] However, in this way, it is often imposs...

Problems solved by technology

[0004] However, in this way, it is often impossible to adjust the falling rate of the grain according to the drying power of the grain dryer, which will easily lead to poor drying quality in the subsequent drying work. Therefore, we propose the grain dryer Grain agency
