Agricultural cereal spiral falling and drying device

Abstract

The invention relates to the field of agriculture, and in particular, discloses an agricultural cereal spiral falling and drying device. The device comprises a shell, a feed hopper, a separation plateand hot air pipes; multiple horizontal stop rollers are uniformly arranged in the connected place of the bottom of the feed hopper with the shell at equal intervals; a horizontal baffle plate capableof being lifted is arranged in the feed hopper; the baffle plate is positioned above the bottom of the feed hopper; multiple stoppers are fixed on the lower surface of the baffle plate; multiple spiral runners are formed under the separation plate in the vertical direction; and the hot air pipes are arranged on the inner wall of the shell corresponding to the spiral runners. Through arrangement of the stop rollers and the stoppers at the bottom of the feed hopper, the unloading quantity can be controlled, so that cereals uniformly enter the feed hopper without blocking meshes, the load of internal equipment is reduced, and smooth falling of the cereals is guaranteed; and the cereals are fully contacted with hot air in the spiral runners for fully drying, and continuously fall down in thespiral runners for drying without needing stop for unloading.

Description

technical field [0001] The invention relates to the field of agriculture, in particular to a spiral falling drying device for agricultural grains. Background technique [0002] With the deepening of the reform of my country's grain circulation system, the full opening of the grain purchase market, and the diversification of grain purchase entities, in recent years some farmers, grain depots, and grain processing enterprises have equipped themselves with grain dryers to dry them in time after purchasing high-moisture grains. Drying and storage, the use of these dryers has greatly alleviated the problem that grains with high moisture content cannot be purchased and stored in time, reduced the loss of grain mildew, and improved the economic benefits of farmers and enterprises. Although the existing agricultural grain dryer realizes the drying of the grain and makes the grain contact with the hot air through vibration, however, due to the large amount of grain entering at one tim...

AI Technical Summary

Problems solved by technology

Although the existing agricultural grain dryer realizes the drying of the grain and makes the grain contact with the hot air through vibration, but due to the large amount of grain entering at one time, the grain is piled up on the screen, so that the grain cannot be dispersed quickly, and the It is beneficial to improve the drying efficiency; in addition, the continuity of the existing drying device is insufficient, and subsequent drying needs to be stopped after unloading. Therefore, it is necessary to improve the existing grain drying device
