Description

A kind of sweet corn sheller unit
Technical field
The invention belongs to agricultural mechanical field, relate to a kind of device being applicable to sweet corn threshing.
Background technology
At present, the product of domestic sweet corn on the market deep processing is seen everywhere, but the machinery carrying out sweet corn threshing processing is rarely found.Only have other manufacturer production, and the technology of some equipment not very ripe, particularly clamp centering poor.Some device efficiency is low; quality can not ensure; have a strong impact on follow-up product increment processing; and the developmental research of thresher machine common is both at home and abroad all that machinery hits, the principle of rubbing; effect is all undesirable; its reason is: the threshing of sweet corn is difficult quite delicate at sweet corn seed shell, and the fringe out-of-shape of the sweet corn of the easy fragmentation of pressurized and different cultivars, size is variant.
Along with sweet corn deep processing is to the development of scale, industrialization, the fast development of planting of sweet corn industry will be driven again thus, and this is in the current development of the West Regions carried out, and all will play very positive impetus, can play good social benefit.Thus in order to improve the added value of sweet corn, strengthen the competitiveness of China's sweet corn in international market, promote the health of China's sweet corn and related industry, develop in order, efficiently, avoid peasant to occur the phenomenon of sweet corn " Higher output is not accompanied by a higher income ", be necessary the development innovation promoting sweet corn sheller unit.
Summary of the invention
The utility model discloses a kind of sweet corn sheller unit, comprises feed hopper, three roller clamping devices, cylinder, frame, cutting knife, receiving hopper and motor.Whole sheller unit vertical, wherein, feed hopper is at the top of device, and center, its underpart is the three roller clamping devices vertically installed, and cutting knife is fixed on bottom three roller clamping devices, and the center, below of three roller clamping devices is receiving hoppers.
Three described roller clamping devices comprise three tapered rolls, the structure of three tapered rolls is identical, for frustum cone structure, its small end upwards, downwards, arrange by equilateral triangle by large end, three tapered roll axis are parallel to each other, form surrounding corn ear, it surrounds on gap upright to feed hopper, lower upright tool setting head; Three tapered roll upper ends are vertically arranged on circular disk rack II respectively by its roll shaft, bearing, and lower end is vertically arranged on circular disk rack I respectively by its roll shaft, bearing, form three roller clamping devices; Three roller clamping devices surround top and bottom, gap and align with circular disk rack II, circular disk rack I disc centre respectively, and circular disk rack I and circular disk rack II are horizontally fixed on lower end and the upper end of cylinder respectively, cylinder is vertically fixed in frame, and there is a through hole at circular disk rack I center, and seed falls thus; Power to be passed on one of them tapered roll in three tapered rolls in three roller clamping devices by motor by electrical machine belt pulley, V-belt I, roll shaft belt wheel I, power is passed to other two tapered rolls by the roll shaft belt wheel II on a roll shaft and V-belt II by this tapered roll again, makes three tapered roll rotating Vortexes; The roll surface material of three tapered rolls is flexible material, and roll surface all has spiral, and this rotary orientation coordinates with tapered roll rotation direction, makes the corn ear uniform descending of clamping; Described motor can be installed under three roller clamping devices and side frame drives three roller clamping devices, and the upside circular disk rack II that also can be installed on three roller clamping devices drives three roller clamping devices.
Described cylinder, circular disk rack I and circular disk rack II, for fixing three roller clamping device and cutting knifes, also can be other shapes, and if circular disk rack I and circular disk rack II can be square or other shapes, described cylinder also can be square or several legs.
Described cutting knife comprises elastic cutter bar and cutter head, cutting knife is fixed on above circular disk rack I, elastic cutter bar stretches into center, space between two tapered rolls, and it is parallel with circular disk rack I card, with tapered roll roll shaft axes normal, the cutter head be arranged in elastic cutter bar points to the disc centre of circular disk rack I, its degree of depth stretched into, and namely cutting depth adjusts by cutting knife fixed position; Elastic cutter bar has retractility; Upwards, cutter head has certain bending to blade tip on cutter head, can thrust in descending corn ear, and along corncob circumference tangential cutting seed.
Described receiving hopper is arranged on immediately below three roller clamping devices, a sieve tilting to install is had in receiving hopper, it is seed outlet below sieve, seed outlet below is seed collecting box, the hypotenuse of receiving hopper has corncob outlet, its open height is a little more than the lower edge of sieve, and corncob outlet is corncob collecting box.
the operation principle of sweet corn thresher:
The small end of sweet corn is put into feed hopper down, and sweet corn enters into three roller clamping devices by feed hopper and surrounds gap, and down, corn ear is clamped by three tapered rolls small end, and cob is vertical, is in three roller clamping devices and surrounds center, gap.Due to three tapered roll rotating Vortexes of three roller clamping devices, and its roll surface there is spiral lines, make sweet corn while being driven and rotating together, be also forced at the uniform velocity to move downward under screw propulsion effect; The flexible roll surface material of tapered roll makes seed damage during clamping can be prevented descending.
When sweet corn moves downward the cutting knife being arranged on three roller clamping device hypomeres, the point of a knife of the cutter head now on cutting knife thrusts microcephaly's seed layer of corn ear, and cutter edge starts to cut along sweet corn seed root anchor ring tangential direction.Because cutter head is arranged in elastic cutter bar, the therefore flexible flexible ability of cutter, can be close to sweet corn seed root always and cut.The knife back of cutter head bends, and the knife back can be made to be close to corncob circumference and in unlikely incision corncob; The corn kernel cut and corncob fall in receiving hopper in the effect that it is conducted oneself with dignity, and under the effect of sieve, sweet corn seed are separated with corncob.Seed drops in seed collecting box through sieve through seed outlet, and corncob rolls out from corncob outlet and falls into corncob collecting box.
compared with prior art, the utility model has following advantage:
1, sweet corn three roller clamping centering is good, can make the sweet corn seed penetraction depth uniformity under cutting;
2. the roll surface material of clamping device adopts flexible material, good to fringe footpath adaptability;
3, the power consumed is little;
4, apparatus structure is simple, is easy to realize, and the shape of tool is simple and easy to manufacture;
5, seed damage rate is low, threshing performance is high.
