Grain dryer capable of winnowing grain husks

Abstract

The invention discloses a grain dryer capable of gas-separating chaff, which includes a drying box. The bottom of the inner cavity of the drying box is provided with a screening net. The screening net separates the inner cavity of the drying box into a drying chamber and a discharge chamber. The drying cavity is equipped with a stirring rod. The middle part of the stirring rod is evenly provided with a number of stirring blades. The bottom end of the mixing rod is evenly provided with a number of scrapers in the circumferential direction. The top of the stirring rod passes through the top of the drying box. The wall of the drying chamber is rotatably connected to the reducer, and the reducer is fixedly connected to the motor shaft of the motor. The top of one side wall of the drying chamber is connected to the air outlet duct; the bottom wall of the discharge chamber is provided with a guide cover, and the discharge chamber is The bottom wall is connected to the main discharge pipe, and one side wall of the discharge chamber is connected to the heating box; the invention is provided with a stirring rod and a stirring blade mechanism to stir the grains, so that the grains are evenly heated and the stirring speed is accelerated; and the rising hot air flow can The chaff in the grain is screened, and then screened twice through the air outlet duct, so that the chaff is completely discharged and the grain particles remain.

Description

technical field [0001] The invention relates to the technical field of drying equipment, in particular to a grain dryer capable of gas-selecting chaff. Background technique [0002] The grain dryer is an assembly of a dryer. It is a general term for various equipment of grain dryer. It can also be a grain dryer, such as corn dryer, rice dryer, rice dryer, wine dregs dryer, etc. We can all call it a grain dryer. According to the relative movement direction of the grain and the airflow, the dryer can be divided into cross-flow, mixed-flow, forward-flow, counter-current and forward-counter-current, mixed-counter-current, forward-mixed-flow and other types. [0003] The existing grain dryers dry unevenly, have a long drying time and low drying efficiency, waste a lot of time, manpower and material resources, and cause a waste of resources; The chaff contained cannot be processed, so that the chaff needs to be processed separately in the follow-up process, which is very inconv...

Problems solved by technology

[0003] The existing grain dryers dry unevenly, have a long drying time and low drying efficiency, waste a lot of time, manpower and material resources, and cause a waste of resources; The chaff contained cannot be processed, so the chaff needs to be processed separately in the subsequent process, which is very inconvenient
