Description
Technical field
The present invention relates to a kind of equipment to different walnut size classification screening, particularly relate to a kind of revolution cage walnut classifying screen.
Background technology
Walnut is liked by people deeply due to its abundant nutritive value.Along with the development of Walnut Industry, in current large-scale production, often need to carry out shell-cracking kernel-taking process to walnut.For realizing walnut machinery shell-cracking kernel-taking, existing walnut huller adopts conventional stone roller to rub with the hands, extruding, the shell breaking method principle of clashing into are peeled off and got benevolence, and one of these walnut huller common features carry out broken shell to walnut exactly in certain gap.And in order to raise the efficiency, the walnut shell-breaking occurred now gets benevolence device to be needed to be put into by walnut in batches to carry out shell-cracking kernel-taking.Because walnut geomery is irregular, put into by walnut batch, the walnut not meeting gap size often just can not get effective broken shell---and the oversize meeting of walnut causes walnut shell overcrushing, and walnut kernel suffers damage; The undersized meeting of walnut causes can not get broken shell.If do not carry out classification to the size of walnut, be so difficult to the precision ensureing broken shell, therefore need the sizing screening carrying out in advance to different size walnut, then process.
For a long time, China's walnut size fractionation generally adopts manual type.Manual grading skill labour intensity is large, time-consuming takes a lot of work, efficiency, precision are all lower, cannot compare, be therefore necessary to provide a kind of plant equipment to walnut classification with mechanization with automatic production line.
Walnut machinery size classifier, mainly by designing mechanical device cleverly, realizes gradually changing of mesh in the course of the work or gap.When walnut moves on such devices, minimum walnut first spills from minimum mesh or gap, and larger walnut spills from larger mesh or gap, the ascending walnut filtering out different size successively.
Through retrieval, current mechanical system walnut size classifier mainly contains 5 kinds of modes, i.e. rolling rods type, roll-type, drum-type, belt and baffle-type.
1. rolling bar type classifier.In rolling bar type classifier, the parallel installation in all rolling bar relative level faces, the spacing in the course of work between rolling bar is changed from small to big.When walnut is carried on rolling bar, when rolling bar spacing exceedes walnut diameter, walnut just falls in the corresponding schizocarp groove in below.The method realizing spacing change between rolling bar mainly contains 2 kinds.1) spacing screw rod method is become.Rolling bar is stuck in two and becomes between spacing screw rod, by connecting by movable connection chain.Rolling bar realizes spacing between rolling bar and changes from small to big under the effect becoming spacing screw rod, thus realizes size fractionation.2) track projection method.Rolling bar two ends are stuck in back-shaped groove, are driven by the drive chain with back-shaped groove.Rolling bar realizes changing from small to big of relative altitude between rolling bar under the effect of track projection, thus realizes size fractionation.
But rolling bar type classifier classification efficiency and effectiveness of classification are all higher, but complex structure, and cost is higher, and classification dimensions not easily adjusts.
2. roll-type size classifier mainly contains double-roll type walnut sorter.Two roller and horizontal plane is angled tilts to install in double-roll type grader, and angled between two roller.During work, two roller counter-rotating.Owing to having angle between two roller, form the classification spacing increased gradually between two roller, again because two rollers tilt to install, walnut rolls down along seam under gravity, and when being rolled to spacing between pair roller and being greater than fruit footpath part, walnut just falls into schizocarp groove between two rollers.
But double-roll type grader classification efficiency is higher, walnut damage is little, and classification dimensions easily adjusts, but effectiveness of classification is not high, walnut under roll across in journey and easily block.
3. drum-type grader.Drum-type grader is divided into again interior schizocarp trough roller cartridge type grader and outer schizocarp trough roller cartridge type grader according to the difference of schizocarp groove inside and outside cylinder.These two kinds of drum-type graders all have several roller units, and each roller unit is evenly covered with aperture, and the small aperture in same roller unit is identical, and the small aperture between different roller unit is different, and aperture increases successively.
During interior schizocarp trough roller cartridge type grader work, cylinder uniform roll, walnut is sent into from drum overhead, carries along cylinder appearance.Walnut successively through the roller unit of different pore size, classification successively from small to large.
During the work of outer schizocarp trough roller cartridge type grader, walnut rises along the inwall of swing roller in cylinder, loosely after rising to certain altitude falls, and the aperture that walnut passes on barrel is fallen in schizocarp groove.Due to the effect of drum rotating and walnut gravity, walnut realizes size fractionation through the roller unit of different pore size successively.
But drum-type grader classification efficiency is high, working stability, there is not the unbalanced phenomenon of power.But effectiveness of classification is not high, classification dimensions not easily adjusts.
4. porose belt sizer.The work strip of porose belt sizer is evenly covered with circular hole, and in same work strip, Circularhole diameter is identical, and different operating interband Circularhole diameter is different, and aperture increases successively.During work, walnut is carried in work strip, and walnut realizes size fractionation through the work strip of different pore size successively.
But classification efficiency and effectiveness of classification are all lower, and classification dimensions also not easily adjusts.
5. baffle-type grader.The circular table center of baffle-type grader is micro-projection, and a ring baffle is installed along workbench edge by portion on the table.The relative table inclination of baffle plate is installed, thus is formed and different pass through gap.During work, walnut rotates with workbench, always upwards make edge of table because the effect walnut of centrifugal force rolls, the gap that etc. the walnut of size does not roll across the size such as not enters different schizocarp grooves, thus realizes size fractionation.
But classification efficiency and effectiveness of classification are not high.
