Operation principle
Corn extracts and is transported in each groove corn connecting gear 2 by the first step, elevating mechanism 1 in hopper, do not fall into the corn in corn connecting gear 2 upper groove smoothly, by manually putting in groove, and corn is made all to be positioned at the same position of groove;
Step 2, corn move along corn connecting gear 2 in groove, when arriving the end, one end of corn connecting gear 2, in corn transport trolley mechanism 3 below the end, corn connecting gear 2 one end falling under gravity into just in time process, corn transport trolley mechanism 3 starts to move along rail assembly 7 with corn under the drive of transmission chain 8;
Step 3, when corn transport trolley mechanism 3 is vertically through first time root cutter structure 4, first time root cutter structure 4 pairs of corn roots carry out first time and cut root, to guarantee that corn can not due to the long generation catching phenomenon of root in follow-up moving process;
Step 4, corn are after first time root cutter structure 4, corn carries out 180 degree of upsets under the drive of corn transport trolley mechanism 3, when corn transport trolley mechanism 3 arrives tipping machine structure 5 place, corn in each corn transport trolley mechanism 3 is all head vertical states down, and the top tip part of tipping machine structure 5 pairs of corns cuts;
Step 5, after tipping machine structure 4, corn transport trolley mechanism 3 carries out 180 degree of upsets again with corn, make when corn transport trolley mechanism 3 reaches second time root cutter structure 6 place, corn is in head vertical state upward, and the root of corn thoroughly excises by second time root cutter structure 6;
After step 6, second time cut root, corn transport trolley mechanism 3 arrives the junction of main machine frame 15 and transportation frame 9, when the corn folder 3-2 in corn transport trolley the mechanism 3 and corn clamping manipulator 12-6 in host computer system meets, corn folder 3-2 in corn transport trolley mechanism 3 opens, and corn clamping manipulator 12-6 simultaneously in host computer system is closed clamps corn, corn transport trolley mechanism 3 and corn clamping manipulator 12-6 complete the handing-over of corn;
Step 7, after corn is clamped by corn clamping manipulator 12-6, the supporting positive cover 12-5 of upper limit mechanism 12-3 first moves down righting mapping maize, syringe needle 12-3-6 thrusts center, corn tip, rotary cutter drive motors 12-2 drives rotary cutter 12-1 to rotate, and rotary cutter drive motors 12-2 moves up under the driving of rotary cutter drive motors orbit, and rotary cutter 12-1 is rotating thrust bottom corn, corn clamping manipulator 12-6 opens, then rotary cutter 12-1 drives corn to rotate together, while rotary cutter 12-1 thrusts bottom corn, upper limit mechanism 12-3 and rotary cutter 12-1 forms the turning cylinder of corn rotation, corn rotation produces centrifugal force makes the crust of corn outwards scatter,
The rotation under the driving of electrical machinery of active force 10 of step 8, main frame 11, the multiple corn grip unit 12 be positioned on main frame 11 lateral wall are also rotated with main frame 11, when corn turns to the below of inflatable body 13, the crust of corn thoroughly outwards dispels out by the gases at high pressure that inflatable body 13 produces;
Step 9, corn are after inflatable body, and rotary cutter drive motors 12-2 power-off, when in time stopping stop mechanism 14, stops stop mechanism 14 and also stop operating due to inertia at the corn rotated;
After step 10, corn stop operating, upper trim ring 12-4 moves down, and lower clamping ring 12-5 moves up, and is firmly clamped by hoja after upper trim ring 12-4 and lower clamping ring 12-5 is closed, upper trim ring 12-4 after closed and lower clamping ring 12-5 together moves down, and is torn by hoja and drags;
After step 11, hoja are torn drag by upper trim ring 12-4 and lower clamping ring 12-5, rotary cutter drive motors 12-2 again starts and drives corn rotation, when corn is through corn residual leaf cleaning machine 18, the crust that corn remains is removed by the residual leaf cleaning machine 18 of corn, and now the crust of corn is thoroughly removed;
Step 12, corn are by after the residual leaf cleaning machine 18 of corn, corn is clamped by corn clamping manipulator 12-6, rotary cutter drive motors 12-2 stops operating and moves down, upper limit mechanism 12-3 moves up, after upper limit mechanism 12-3 and rotary cutter 12-1 departs from corn, corn clamping manipulator 12-6 opens, and corn naturally drops to corn induction system and discharges.
