Seed drying box with screening function

Abstract

The invention discloses a seed drying box with a screening function, and belongs to the technical field of seed drying. The seed drying box is used for solving the problem that the drying effect cannot be achieved as most of existing seed dryers cannot remove impurities such as pods and aggregates in seeds before drying, and dried seeds are easily re-moisturized in a screening process if screeningis performed after drying. The screen drying box comprises a box body, wherein a charge hole is formed in the top of the box body; a first filter assembly, a drying assembly and a second filter assembly are sequentially arranged in the box body from top to bottom; the drying assembly comprises a drying bin, a heater, an electric motor, a rotary shaft, a bearing base and fan blades; the drying binconsists of side plates and a bottom plate, and an opening is formed in the top of the drying bin; the cross section of the bottom plate is semicircular; the bottom plate is movably connected with the side plates; a heater is arranged on the lower surface of the bottom plate; and the second filter assembly comprises a filter plate, a supporting plate, a cleaning device and a transmission caterpillar band, and a discharge hole is formed in the output end of the transmission caterpillar band.

Description

technical field [0001] The invention relates to the technical field of seed drying, in particular to a seed drying box with a screening function. Background technique [0002] Generally, newly harvested seeds have a high moisture content. If appropriate measures are not taken to deal with them, the respiration intensity of high-moisture seeds will be high during long-term storage, and a large amount of heat will be released, which will easily cause the seeds to go moldy, or due to lack of oxygen. Breathing produces alcohol and is poisoned, or is exposed to low temperature and freezes to cause death. So seed companies usually place the seeds in a dryer and use the wind to dry them. [0003] In the existing seed drying technology, the commonly used methods for drying seeds are artificial ventilation and drying or natural drying. Restrictions, low drying efficiency and high labor intensity. At present, there are also seed dryers on the market, but most of them do not have th...

Problems solved by technology

[0004] In order to solve the problem that most of the existing seed dryers cannot remove impurities such as pods and sand and gravel in the seeds before drying, and then screen after drying, the dried seeds tend to become wet again during the screening process, thereby The problem that the effect of drying cannot be achieved, the present invention provides a seed drying box with screening function
