Embodiment 2
[0056] A control method for grain drying equipment, comprising sequentially performing the following steps on baffles in a drying box from bottom to top:
[0057] S1 controls the nth baffle to rotate to the working position, n∈{1,2,...,N}, N is the number of baffles;
[0058] S2 controls the solenoid valve corresponding to the nth baffle to open, so that the grains are sprinkled on the nth baffle;
[0059] S3 detects the nth weight signal of the grain on the nth baffle;
[0060] S4, when the nth weight signal reaches the weight threshold, control the solenoid valve corresponding to the nth baffle to close;
[0061] Optionally, the control method for grain drying equipment further includes the following steps:
[0062] S5 controls the baffles in the drying equipment to fall in sequence from bottom to top after the grain reaches the preset drying time.

Abstract
The invention relates to the field of grain drying, in particular to a grain dryingmachine. The grain dryingmachine comprises a box body, a feeding bin, a feeding auger, a feeding opening, baffles,a weight sensor, an air cylinder, a hot blast stove, a discharging auger and a controller; a layering structure is arranged on the inner wall of the box body, and is composed of multiple baffles, grains can be more evenly dried, the drying efficiency is high, energy consumption is low, cost is reduced, the grain drying temperature is adjustable, the drying process is subject to precise quantitative operation, and the problem that the drying temperature is not uniform is solved.
Description
technical field [0001] The present application relates to the technical field of drying equipment, and in particular, to a grain drying equipment and a control method thereof. Background technique [0002] After the grain is harvested, it generally needs to be dried for many days before it can be safely stored in the warehouse; however, during the busy agricultural period, especially when thunderstorms are frequent or rainy weather for many consecutive days, the grains stacked together will be damp due to their own humidity. And the heat is extremely easy to mold and rot, causing huge losses to farmers. [0003] Grain drying is an important step in agricultural production. Grain dryers use control of temperature, humidity and other factors to reduce the moisture content of grains. In the above cases, grain dryers are usually employed to dry the grains. The drying system of the existing grain dryer on the market includes a hot air system, a hot air pipe, and a drying cylind...
