Problems solved by technology

[0003] In the above process, there are several key factors: 1. The moisture content of the air generated during the drying process is relatively high. When this part of the air is directly applied to the subsequent slow recovery process, the drying effect will not be good.
2. During the drying process, due to the fast drying spe

Example Embodiment

[0055] Example 1

[0056] The structure of the drying machine provided by the present invention is as follows figure 1 Shown, including:

[0057] The main body 1 of the drying silo is composed of a drying silo 5 located on the upper layer and a slow silo 6 located on the lower layer, and the drying silo 5 and the slow sluice storage 6 are connected;

[0058] Feeding device 2 is used to feed grains into it, which can be a funnel and other equipment;

[0059] The lifting device 3 connects the feeding device 2 with the feeding device 4, and is used to lift the grain from the feeding device 2 to the feeding device 4 located on the upper part of the drying bin main body 1. The lifting device 3 can be a conveyor belt and other devices;

[0060] The feeding device 4 is used for feeding grains into the drying bin 5, and equipment such as a vibrating screen can be used;

[0061] The barriers 8 are distributed in the drying silos 5 and the slow silos 6 to block the grains and prevent them from fa...

Abstract

The invention relates to an agricultural drying mechanism and an automatic control method thereof, in particular relates to an agricultural mechanism for drying grain and an automatic control method thereof, and belongs to the technical field of agricultural mechanisms. The drying mechanism is mainly applied to the grain drying; water produced in the grain drying process is drained through the drying mechanism during the drying stage, and meanwhile, the air is returned to a tempering bin after the heat is recovered from the heat, thus the requirement on low-temperature and high-flow-rate drying air in the tempering process is met, and the grain crackle ratio is decreased; meanwhile, the grains carried out during the drying process can be separated out and returned to the tempering bin, so that the grain utilization rate is increased.

Description

technical field [0001] The invention relates to an agricultural drying machine and an automatic control method thereof, in particular to an agricultural machine used for grain drying and an automatic control method thereof, and belongs to the technical field of agricultural machinery. Background technique [0002] In the process of drying grains (rice, wheat, millet, corn, etc.), the main drying process is divided into two stages, one is the drying stage, the process of this stage is mainly the transfer and vaporization of the moisture on the surface of the grain, The moisture drying process is fast, and air with high water content will be produced; the latter section is the slow su section, which is mainly the process of transferring the moisture inside the grain to the outside. Due to the slow transfer process, if higher temperature and smaller flow rate are used When there is too much air, the volume will cause the surface of the grain to crack (burst rate). Therefore, ...
