Infrared corn cob drier capable of elastically cropping

Abstract

The invention provides an infrared corn cob drier capable of elastically cropping. The infrared corn cob drier is characterized in that a plurality of conveying devices driven to rotate by a transmission device are arranged in a box body, a plurality of material shifting rods are fixed to bent boards which correspondingly and inwards extend out of two chains of the same conveying device through two connectors at end parts, material supporting grooves are respectively formed under an upper horizontal section and a lower section horizontal of the chains corresponding to each conveying device, a cropping device which is supported on the side wall of the box body through a cross beam is arranged under the tail end of the material supporting groove at the upper section, a plurality of supporting sleeves which are parallel to supporting boards are uniformly fixed between the two supporting boards which are fixed to the cross beam and are provided with a chute, rolling sleeves supported on a supporting rod can compress springs through pin shafts and telescopic rods and can slide axially along the inner holes of the supporting sleeves, material guiding grooves are formed in positions under the tail end of the material supporting groove in the lower section, and radiation devices are arranged above the material supporting grooves; a feed opening is formed in the top of the box body, and a discharge opening is formed in the bottom of the box body. The infrared corn cob drier disclosed by the invention is high in drying efficiency, is good in drying uniformity, is simple in structure and is reliable in work.

Description

technical field [0001] The invention provides an elastic blanking infrared corn ear dryer, which is mainly used for dehydrating and drying wet corn ears with high moisture content just after being picked from corn stalks. Background technique [0002] China is a large agricultural country, especially in Shandong, Henan and Northeast China, which are the major food producing areas such as corn. With the development of the breeding industry and the increase in the demand for feed, the planting area of ​​corn has gradually expanded, and the output has increased year by year. The harvest moisture of corn is generally 25%~35%. If there is no good corn drying equipment, it will cause a lot of loss due to excessive moisture and mold. Therefore, farmers' demand for corn dryers is becoming more and more urgent. It is of great significance to develop corn dryers with high precipitation, good drying uniformity and high quality to promote the development of corn industry. [0003] At ...

AI Technical Summary

Problems solved by technology

The corn cob dryers involved in the above patents all adopt hot air convection drying, which consumes relatively high energy consumption and sometimes causes corn kernels to burst. After changing to infrared radiation drying, a national invention patent was applied for, and the patent number is: ZL201310056847.7 ; After changing to a rotatable shifting rod to make the feeding trough convenient to support, a national invention patent was applied for, the application number is: 201310060839.X; after the limit sleeve was added, a national invention patent was applied again, the patent number is : ZL201310065945.7; After adding a toggle wheel or a toggle mechanism, it applied for a national invention patent, the application numbers are: 201410060366.8 and 201410110342.9; after changing to a straight rod toggle, it applied for a national invention patent, and the application numbers are: 201410227754.0

Since the ears of corn are approximately conical, the diameter difference between the large and small heads is generally about 10mm. When passing through the long strip guide groove, the small head will fall first and the big head will fall later, so that some corn ears cannot accurately enter the two feed rods after falling. In between, so that the drying effect of rolling and slipping could not be achieved. Therefore, after changing to flipping and blanking, an invention patent was applied for, and the application number is: 201510124525.0

However, it was found through experiments that the effect is not ideal
