Grain drying device for agricultural science experiment

Abstract

The invention discloses a grain drying device for an agricultural science experiment. The grain drying device comprises a bottom plate, four supporting plates are welded to the outer wall of the top of the bottom plate, the outer walls of one sides of the four supporting plates are provided with the same drying box in a welded mode, a mounting base is welded to the center of the outer wall of thetop of the drying box, and a motor cover is fixed on the outer wall of the top of the mounting base through bolts; a round hole is formed in the center of the outer wall of the top of the mounting base, a motor is fixed on the inner wall of the motor cover through a bolt, and a motor output shaft is inserted into the round hole; and a cover shell is welded to the inner wall of the top of the drying box, first through holes are formed in the inner wall of the bottom of the cover shell and the outer wall of the top of the drying box correspondingly, and a first bearing is welded to each of the inner walls of the two first through holes. According to the grain drying device for the agricultural science experiment, the drying efficiency of the device is high; and solid impurities with small size such as sand in grain can be removed during drying, and thus the practicability of the device is improved.

Description

technical field [0001] The invention relates to the technical field of grain drying devices, in particular to a grain drying device for agricultural science experiments. Background technique [0002] In agricultural scientific research, in order to increase the yield of crops, it is necessary to carry out relevant inspection experiments on the planted grains. During the experiment, the grains need to be dried to remove the moisture in the grains. In the process, a grain drying device is required. [0003] After retrieval, the Chinese patent number is CN 205192140 U, ​​which discloses a grain dryer for agricultural laboratories, including a box body, a solar panel, a ventilation port, a door, a drawer, a sliding wheel, a motor, two brackets, The baffle, the grain storage barrel, the fan, the heating wire, the battery and the rotating shaft, the solar panel is fixed on the top of the box, the grain storage barrel is located between the two brackets, connected with the two sup...

[0003] After retrieval, the Chinese patent number is CN 205192140 U, ​​which discloses a grain dryer for agricultural laboratories, including a box body, a solar panel, a ventilation port, a door, a drawer, a sliding wheel, a motor, two brackets, The baffle, the grain storage barrel, the fan, the heating wire, the battery and the rotating shaft, the solar panel is fixed on the top of the box, the grain storage barrel is located between the two brackets, connected with the two supports through the rotating shaft, and can rotate around the rotating shaft, The motor is connected to the rotating shaft through a transmission mechanism, and the grain storage barrel is divided into six compartments along the diameter, each compartment is hinged with a baffle plate, and each baffle plate is evenly opened with a plurality of holes, the above-mentioned patent has the following disadvantages when working Disadvantages: 1. The grain is dried in a relatively unsealed space, which will generate more dust. 2. During the drying process, since the outer wall of the box containing the grain has multiple holes distributed in a ring, Although it can remove the solid impurities in the grain, it will not be easy to clean when the hole is blocked. 3. The grain is not heated evenly, and the grain will accumulate at the bottom of the container due to gravity. Even if the container rotates, the grain will not be lifted. So it doesn't heat up well
