Infrared corncob drying machine with limiting sleeve

Abstract

The invention provides an infrared corncob drying machine of a limiting sleeve. The infrared corncob drying machine is characterized in that a box body is internally provided with a plurality of conveying devices driven by a transmission device to run; one end of a stud is screwed into a screw hole of an inner side chain section of a chain; the two ends of material pulling rods are hollowly sleeved in the middle of the stud; a limiting sleeve provided with a spring and steel balls in a blind hole is fixed in the middle of the stud so that the two steel balls fall into spherical concave pits of the material pulling rods; parts of each conveying device, which correspond to upper and lower sections of a horizontal section of a chain, are respectively provided with material conveying grooves; material guide grooves are arranged below the material conveying grooves; radiation devices which downwards radiate infrared rays in a single direction are arranged above the material conveying grooves; circular-arc-shaped limiting rods I and II are respectively arranged at the two ends of each conveying device so that when each material pulling rod is operated to the chain to change the direction, on one hand, the material pulling rods rotate along chain wheels, and on the other hand, the material pulling rods do reversed autorotation with the same co-rotation angle speed around the stud; and a feeding opening is arranged on the top of the box body, and a discharging opening is formed at the bottom of the box body. The infrared corncob drying machine disclosed by the invention has the advantages of high heat transferring efficiency, low energy consumption, accurate position and reliable work.

Description

technical field [0001] The invention provides an infrared corn ear dryer with a limiting sleeve, 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. [000...

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 the corn kernels to burst. After changing to infrared radiation drying, the national invention patent was applied for, and the application number is: 201310056847.7; changed to After the rotatable material lever is used to facilitate the support of the feeding trough, a national invention patent has been applied for, and the application number is: 201310060839.X

However, the position of the rotary rod-type infrared corn cob dryer involved in this patent is determined by an interference fit between the limit sleeve and the stud, resulting in inaccurate and consistent positions of the rods; relying on the elastic deformation of the rods to The steel ball is extruded from the spherical pit, resulting in insufficient work reliability
