Abstract

The present invention discloses the rice huller of a kind of separable brown rice and husk.Adopt the feeding roller pan feeding, the eccentric wheel oscillating plate separates, and the circulating air cereal cleaning can be finished rice huller paddy simultaneously, separates and puies forward functions such as shell, collection.Rough shell good separating effect can reduce floor space and equipment investment, and power savings is remarkable, reduces the ton-grain processing cost.Has better environmental-protecting performance.

Description

Rice huller

The invention belongs to the combination of hulling machine and rough shell separation machinery.

About cereal shelling, separation machinery, present common employing multimachine compound mode.Shown in accompanying drawing one, be one by hulling machine 1, separator 2, husk collecting device 3, blower fan 4, purify autonomous device such as expansion chamber 5 and be interconnected to a cover bulky systems through the pneumatic conveyer road.Its deficiency is: this system's fund input is big, floor space is big, product quality is difficult for accurately control, power consumption and maintenance cost height.

The objective of the invention is to disclose the rice huller that a kind of hull paddy and rough shell discrete group are integrated.Not only reduced equipment investment, reduced the ton-grain cost, but also better grain milling performance and separating property can have been arranged.

Rice huller valley system system, rough shell piece-rate system circulating air cereal cleaning system, casing and drive motors have been the present invention includes, on traditional hulling machine architecture basics, do following improvement, supplied materials direction at the speed rubber roll of hulling machine is equipped with feeding roller, and the roll shaft of above-mentioned three rollers is parallel.Material is in the stable and balanced input speed rubber roll ridge paddy shelling of the axis direction of material roller.Be provided with the eccentric wheel oscillating plate, rough shell mixture flows into dustpan shaped vibration plate, rough shell mixture is thrown by vibration force, the landing of heavier brown rice gravitate is also discharged from the brown rice exit.Lighter husk sucks air inlet duct with air-flow.Also have a circulating air cereal cleaning system to form by axial fan, discharge auger, air-return duct, air draught road, air regulating board and air channel regulating system.The husk that sucks the air channel leans on the negative pressure effect in the draught fan impeller rotation, enters the diffusion hopper, and the dilatation step-down is deposited to the discharge auger after slowing down, and discharges from the rice husk mouth.Circulating air flow back into circulation air path through impeller center low-pressure area.

The present invention has the combination function of many units, reduces floor space and equipment manufacturing cost.

Fig. 1 is the prior art fundamental diagram;

Fig. 2 is a front view of the present invention;

Fig. 3 is Fig. 2 side view.

Wherein: 1 is hulling machine, and 2 is the bellows type separator, and 3 is grain saver, and 4 is blower fan, and 5 for purifying expansion chamber.Among Fig. 2: 6 is feeding roller, and 7 is fast rubber roll, and 8 is slow rubber roll, and 9 is motor 1,10 are eccentric wheel vibration panel assembly, and 11 is hopper, and 12 are the air draught road, and 13 is air channel tuned plate handle, 14 is centrifugal blower, and 15 is the discharge auger, and 16 is air-return duct, and 17 is motor 2.

Paddy expects that through the people mouth falls feeding roller 6, and material flows to 7,8 of two speed rubber rolls that variable speed rotates in opposite directions with equilibrium, through extruding and friction, rice husk is broken, and forms the mixture of brown rice and shell, enters eccentric wheel vibration plate device 10.Utilize circulated air and gravity double action, brown rice enters hopper 11, and light husk sucks in the air channel, and the wheel revolution space is drawn in the diffusion hopper in blower fan 14, and dilatation, step-down, deceleration, husk are discharged through the discharge auger.Because containing the shell air-flow circulates in circulation air path, foreign material one dust does not leak, and atmosphere be can not form pollution.

Only 4m is taken up an area of in the present invention ², only can have a machine in operation with 2 motors, power savings is obvious, and the ton-grain processing cost significantly reduces, and the brown rice quality is good, separates thoroughly.

Claims (1)

1, the rice huller that is combined into one of a kind of hulling machine and seperator, it includes rice huller valley system system, rough shell piece-rate system, circulating air cereal cleaning system, casing and drive motors, it is characterized in that: the supplied materials direction of the speed rubber roll of hulling machine is equipped with feeding roller, and feeding roller is parallel with the speed rubber roller.Material is through the feeding roller equilibrium people's speed rubber roll rice huller paddy shelling that falls, described rough shell piece-rate system is provided with the eccentric wheel oscillating plate, circulating air cereal cleaning system includes axial flow blower, discharge auger and air-return duct, air draught road, air regulating board and air channel tuned plate handle, and air-return duct, air draught road, draught fan impeller and impeller middle spindle form circulation air path to low-pressure area.
