Description

Technical Field

[0001] The invention relates to a wheat seed protection storage device, belonging to the technical field of agricultural storage. Background Art

[0002] The storage of wheat seeds is a very important link in agricultural production. It is directly related to the quality of seeds and the yield and quality of the next season's crops. The storage of wheat seeds requires comprehensive consideration of multiple factors to ensure that the seeds are dry, clean and safe in order to maintain their optimal quality and germination rate.

[0003] There is a common wheat seed storage technology on the market now. Two storage containers are used, one of which has a drying function to drain the internal moisture. The wheat seeds that pass the real-time moisture test will be transferred to the other storage container. However, this storage technology, especially the drying technology, requires the wheat seeds to be continuously dried after failing the moisture test. Since the hot air is blown from bottom to top, this often causes the seeds below to be too dry, while the seeds above are still very moist and do not meet the standards. The drying effect is poor, which affects the quality of the wheat seeds, and the efficiency is also low. Summary of the invention

[0004] The purpose of the present invention is to solve the technical problems existing in the prior art of poor drying effect, low efficiency and easy impact on seed quality, and to provide a wheat seed protection and storage device.

[0005] The present invention is achieved through the following technical solutions: That is, a wheat seed protection and storage device, comprising two tank containers, a drying bin and a storage bin, an exhaust fan is arranged at the top of the drying bin, the two tank containers are connected by a transfer screw conveyor, the drying bin is arranged on a base on the ground, a honeycomb plate covered with air holes is installed at the bottom of the drying bin, at least one horizontal screw conveyor is arranged on the honeycomb plate, and a circular walking mechanism for driving the horizontal screw conveyor to make a circular motion is installed at the outer end of the horizontal screw conveyor; A lifting screw conveyor is provided at the center of the drying bin. The rotating shaft of the lifting screw conveyor passes through the honeycomb plate. A lifting motor is installed at the bottom of the rotating shaft of the lifting screw conveyor. A moisture detector is installed on the top of the lifting screw conveyor. The bottom of the transfer screw conveyor is connected to the moisture detector.

[0006] The wheat seeds entering the drying bin are continuously gathered at the bottom to the center of the drying bin under the action of the horizontal screw conveyor, and the seeds gathered at the center are lifted upward by the lifting screw conveyor. The seeds qualified by the moisture detector are transferred to the storage bin by the transfer screw conveyor, and the seeds unqualified by the moisture detector are lifted to the highest point and then fall down, and continue to be dried until the moisture content is qualified and transferred to the storage bin for long-term storage. The present invention cyclically dries the wheat seeds and then transfers them for long-term storage, thereby ensuring the effect of long-term storage of the wheat seeds, and the drying efficiency is high, which minimizes the adverse effects on the quality of the wheat seeds.
