Description

A kind of hulling machine

Technical field

The present invention relates to a kind of husking apparatus for rice, more particularly, to a kind of hulling machine enabling fixed roll dynamic roller rotating speed exchange.

Background technology

At present, the method for paddy husking is, with two diameter same rotational speed, the rubber roll of opposite operating, certain By being extruded to Oryza glutinosa and effect is torn in stranding under pressure, reach the purpose of shelling, but the continuity with hulling machine process time, The high rubber roll quick abrasion of rotating speed, the relatively slow rubber roll abrasion of rotating speed is slow, and the linear velocity of two rollers and linear speed difference so can be made gradually to drop Low, lead to glue shell rate and production efficiency to decline, general solve problem mode be shut down after artificial unloading carried out to rubber roll and exchange, Its production efficiency and shelling effect can be ensured, thus increased labor intensity, and shutdown leads to the continuous production time to shorten, Reduce Yield and quality, production cost rises.

Content of the invention

In order to overcome the above-mentioned deficiencies of the prior art, the invention provides one kind need not change rubber roll, as long as according to production When shell-breaking rate situation, carry out fork shift speed governing, keep two rubber roll linear differentials relatively stable, reduce labor intensity it is ensured that continuous Processing, the hulling machine of improve production efficiency.

The above-mentioned purpose of the present invention is realized by such technical scheme, a kind of hulling machine, includes fixed roll, dynamic Roller, fixed roll axle, action roller shaft, drive, fixed roll seat, feed hopper base, drawing-in device, rubber covered roller seat, shaft end ring, rice hulling chamber, base plate And pendulous device；It is characterized in that：It is additionally provided with change gear box, one end of described fixed roll axle and action roller shaft extends respectively into change In fast gear-box, and fixing little gear and fixing gear wheel are arranged on fixed roll axle, fixing little gear and fixing gear wheel are double Even gear, arranges dynamic roller gear on action roller shaft；It is provided with speed change between the fixed roll axle in change gear box and action roller shaft to turn Changing device, described variable-speed conversion device includes power transmission shaft, bridge shaft and shift actuating device；Described power transmission shaft sets removable gear train, Described removable gear train is doubly-linked gear, and including shift gear wheel and shift little gear, shift little gear can be with fixing canine tooth Wheel matches, and shift gear wheel can be matched with fixing little gear；Described bridge shaft is provided with can be little with shift gear wheel and shift Gap bridge little gear and gap bridge gear wheel that gear matches, gap bridge little gear is matched with dynamic roller gear, gap bridge little gear and mistake Bridge gear wheel is doubly-linked gear；Described shift actuating device is arranged on the case lid of change gear box, and shift actuating device, by gear change hand lever, is pressed Spring, rotating shaft, connecting rod, little axle and sliding sleeve composition, sliding sleeve extends and is connected between shift little gear and shift gear wheel；Described biography Moving axis connects drive, is driven wheel drive power transmission shaft, and power transmission shaft drives shift gear wheel and shift pinion rotation, is passed by gear Dynamic, thus driving fixed roll and dynamic roller to relatively rotate；When needing speed change, described removable gear train is moved by shift actuating device, real Now move roller and relatively fast Yu the slow mutual conversion of fixed roll linear resonance surface velocity, even if the linear velocity on fixed roll surface is faster or slower than dynamic roller The linear velocity on surface.

Described power transmission shaft is splined shaft.

Its transmission principle is：Because power transmission shaft connects drive, when drive rotates, drive drive axis, on power transmission shaft Shift gear wheel and shift pinion rotation, shift gear wheel drives dynamic roller gear by the gap bridge little gear of bridge shaft, from And driving dynamic roller, shift little gear passes through fixed roll canine tooth wheel drive fixed roll axle thus driving fixed roll to rotate；In production process, can lead to Cross shift actuating device and move described removable gear train, that is, when the shift gear wheel on power transmission shaft and gap bridge little gear engage, shift When little gear and the engagement of fixed roll gear wheel, fixed roll rotating speed is faster than dynamic roller rotating speed：When the shift little gear on power transmission shaft and gap bridge are big Gear engages, and when shift gear wheel and the engagement of fixed roll little gear, fixed roll rotating speed is slower than dynamic roller rotating speed.

Realize the present invention, due to being provided with variable-speed conversion device, rubber roll need not be changed, as long as operation shift actuating device moves tooth Wheel group, can be achieved with relatively fast Yu the slow mutual conversion of the linear velocity on dynamic roller and fixed roll surface, makes rubber roll even wearing, and keep Optimal service behaviour, thus reducing broken rice rate, improves yield rate and quality, energy saving, improve production efficiency.
