Tea seed grading winnowing machine

Abstract

The invention discloses a tea seed grading winnower and belongs to the technical field of grading winnowing equipment of agriculture and forestry products. The tea seed grading winnower comprises a blower, an air duct, an air inlet pipe, a dust collector and an air return pipe, which are connected in sequence, wherein a feed hopper is mounted at the feed end of the air duct; a full seed discharging hopper, a non-full seed discharging hopper and a impurity and husk discharging hopper are arranged below the air duct in sequence; a feed adjusting mechanism is arranged at the bottom of the feed hopper; the feed adjusting mechanism comprises a feed adjusting plate, a handle, a locking handwheel and an arc-shaped guide plate; the feed adjusting plate is fixedly connected with the handle to form an included angle; a locking hole is formed in the handle; and a locking handwheel shaft passes through the locking hole and an arc-shaped guide groove in the arc-shaped guide plate. According to the physical characteristic that full seeds, non-full seeds, moldy tea seeds and empty husks have different densities, the tea seed grading winnower adopts strong wind to blow seeds or empty husks, which have different densities, to move different distances, and a plurality of different regions are divided according to the distances of falling points, so that the four kinds of materials are sorted accurately.

Description

technical field [0001] The invention belongs to the technical field of classification wind separation equipment for agricultural and forestry products, and in particular relates to a tea seed classification wind separation machine. Background technique [0002] Tea oil processing enterprises urgently need to classify tea seeds and separate shell seeds before tea seed drying and pressing, so as to adapt to pressing tea oil of different quality grades. The invention divides the tea seeds with full particles into one category, the semi-full tea seeds into one category, the mildewed tea seeds and empty shells into one category, and the dust, light impurities and broken shells into one category. At present, manual sorting is mainly used, which not only has low efficiency and high labor intensity, but also has high labor cost and long construction period, which is not suitable for industrial production and processing. The research on sorting technology and equipment in this area h...

Problems solved by technology

At present, manual sorting is mainly used, which not only has low efficiency and high labor intensity, but also has high labor cost and long construction period, which is not suitable for industrial production and processing. The research on sorting technology and equipment in this area has just started

The tea seed kernel is wrapped in the shell, and the outer diameters of plump tea seeds, unfull tea seeds and mildewed tea seeds are not much different, so the screening method is basically ineffective, although there is a specific gravity screening equipment in corn Small particles such as tea can be sorted, but tea seeds are too large to be practical, and the sorting accuracy is not enough

The patent No. CN201320673418 is the invention patent of "a device for grading and selecting camellia oleifera seeds". Combined with screening, the equipment cost is high, the structure is complex, and the falling material collection area range of the high-quality seed hopper, mildewed seed hopper, and deflated seed hopper cannot be flexibly adjusted according to the incoming materials, and the classification accuracy is not high
