Infrared corn cob drying machine with shifting mechanisms

Abstract

The invention provides an infrared corn cob drying machine with shifting mechanisms, which is characterized in that a box is internally provided with a plurality of conveying devices driven to run by a drive device I, one end of a stud is screwed into a screw hole in a chain link on the inner side of a chain, two ends of a shifting lever are idly arranged in the middle of the stud in a sleeving manner, a blind hole is internally provided with a spring and a steel ball stop collar which are fixed in the middle of the stud, two steel balls fall into a spherical pit of the shifting lever, each conveying device is provided with chute feeders respectively corresponding to an upper horizontal section and a lower horizontal section of the chain, a guide chute is arranged below the tail end of the chute feeder, a radiation appliance is arranged above the chute feeder, two ends of each conveying device are respectively provided with a limiting rod I and a limiting rod II, and a shifting mechanism is arranged at each chain wheel below a feed opening, so as to force each shifting lever to do reverse autorotation with speed equal to that of a corotation angle around the stud while corotating along with the chain wheel when travelling to the chain wheel for reversing; the feed opening is formed in the top of the box, and a discharge opening is formed in the bottom of the box. The infrared corn cob drying machine is high in heat transfer efficiency, low in energy consumption, reasonable in structure and reliable to work.

Description

technical field [0001] The invention provides an infrared corn cob dryer with a toggle mechanism, which is mainly used for dehydrating and drying wet corn cobs with high moisture content just after picking 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] A...

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

However, it has been found through tests that when the limit sleeve infrared corn ear dryer involved in this patent moves to the sprockets below the feed inlet along with the chain, the two U-shaped sides of the lever are always In the vertical state, the U-shaped bottom edge of the feed rod is higher than the lowest point of the limit rod II, so that the feed rod cannot smoothly transition to the inner wall of the box near the sprocket end of the sprocket below the feed inlet. side, so that after the shifting rod is reversed at each sprocket located below the feed inlet, it is impossible to maintain the situation that "the two U-shaped sides of the shifting rod are in a vertical state, and the U-shaped bottom is facing upwards". In this state, continue to shake the ears of corn for drying
