Vegetable seed air-drying apparatus

Abstract

The invention discloses a vegetable seed air-drying apparatus, which comprises an air-drying chamber, wherein the lower end of the air-drying chamber is provided with a bracket, a circulation conveying belt is arranged in the air-drying chamber, both ends of the circulation conveying belt penetrate through the side plates of the air-drying chamber, the positions of two extending parts of the circulation conveying belt are respectively provided with a un-dried seed hopper and a dried seed hopper, the upper end of the air-drying chamber is symmetrically provided with two movable cover plates, high-power illumination lamps are fixed on the inner sides of the movable cover plates, a flipping mechanism is arranged between the two movable cover plates and comprises a base, driving motors and driving blocks, the driving block are rotatably connected to the base, the output shafts of the driving motors are connected to the driving blocks through pulling ropes, one side on the lower portion of the air-drying chamber is provided with a drying gas inlet pipe, the other end is provided with a gas outlet pipe, and the inner side of the bottom plate of the air-drying chamber is provided with a heating plate. According to the present invention, the vegetable seed air-drying apparatus has the reasonable structure design; and the seed is conveyed by arranging the circulation conveying blet, such that the uniform spreading can be achieved, the labor intensity can be reduced, the automated material collecting and feeding can be easily achieved, and the air-drying efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of seed drying equipment, in particular to a vegetable seed drying device. Background technique [0002] The water content of seeds is an important factor for the safe storage of seeds. High seed moisture content is the main reason for the decrease of seed germination rate. Seeds with low water content will inhibit respiration and physiological activity, increase stability and be safe to store. Therefore, before the seeds are put into the warehouse, they should be fully dried and the water content should be reduced to make the water content below the safe level. Drying seeds can kill bacteria, increase seed permeability and water absorption capacity, increase germination rate and germination potential, and ensure emergence rate. [0003] Traditionally, due to untimely drying or incorrect methods, the water content of the seeds is high, and it is easy to cover them during storage, resulting in a decrease i...

Problems solved by technology

There are deficiencies in the existing seed drying device. First, the function is single, and it can only be dried outdoors or indoors, and cannot make full use of weather conditions on the basis of ensuring drying efficiency to reduce production costs; second, it cannot realize industrial continuous drying. Manual tiling, rewinding and unwinding operations are required, and the drying efficiency is low
