detailed description of the invention:
Below in conjunction with accompanying drawing, the invention will be further described:
Embodiment 1:
As shown in figures 1-8, the pearl screening plant of the present embodiment 1, comprise sphericity screening drive unit 2, sphericity screening drive unit 2 drives connecting crank endplay device () 3, crank and rocker mechanism (one) 3 is arranged on fixed head 4, and crank and rocker mechanism () 3 drives pearl sphericity screening cup 1 to do elliptical orbit motion; Pearl sphericity screening cup 1 is rounding mesa-shaped, and pearl sphericity screening cup 1 wall of cup is provided with the identical slotted eye of multiple size 5, and wherein slotted eye 5 is longitudinal slotted eye, is evenly distributed on the middle upper end of pearl sphericity screening cup 1 wall of cup.
Pearl sphericity screening cup 1 inner surface is smooth, to reduce the friction of pearl fish pearl sphericity screening cup 1, reduces the wearing and tearing to pearl surface.
Wherein, screening drive unit 2 is stepless time adjustment motor, and stepless time adjustment motor is arranged under fixed head 4, drives the crank and rocker mechanism () 3 connecting and be placed on fixed head 4, crank and rocker mechanism () 3.
Be provided with crank 18 at crank and rocker mechanism () 3, crank 18 drives rocking bar 20 to rotate by connecting rod 19, and wherein, crank 18, connecting rod 19 and rocking bar 20 are linked by bulb, and pearl sphericity screening cup 1 is connected with crank 18.
Sphericity screening drive unit 2 is provided with the first bracing frame 21, first bracing frame 21 and is fixedly installed on fixed head 4 lower end, and such structure can make sphericity screen drive unit 2 a more stable running environment.
When starting to screen pearl sphericity, start stepless time adjustment motor, stepless time adjustment driven by motor crank and rocker mechanism (one) 3 high-speed rotation, the high-speed rotation of crank and rocker mechanism () 3 drives pearl sphericity screening cup 1 also to do high-speed rotation, and the pearl being placed in pearl sphericity screening cup 1 does the steady circular Far East, because pearl itself has inertia, always move along tangential direction, but due to centripetal force effect, make it not fly off at a tangent, and be limited circumferentially to move.Suddenly disappear when providing the bonding force of centripetal force, pearl is due to the inertia of itself, will move along tangential direction, gradually away from the center of circle, stepless time adjustment motor can drive pearl sphericity to screen cup 1 and do different rotating speeds motion, the centripetal force that pearl is subject under different rotating speeds is different, realizes the screening to pearl.
Pearl screening plant is also provided with pearl blanking device 6, pearl blanking device 6 comprises the cylinder 7 be set in outside pearl sphericity screening cup 1, cylinder 7 inwall lower end is provided with ring groove 15, ring groove 15 is positioned at the lower end of the horizontal level of slotted eye 5, and is communicated with the pearl discharging opening 8 that cylinder 7 sidewall bottom is arranged.Wherein, cylinder 7 be upper and lower, in all empty tubular, be only provided with annular groove 16 at end position on the lower side, for accepting the pearl of dishing out from slotted eye 5.
Wherein, the fixed bar 17 that cylinder 7 is connected by its outer wall is fixed on fixed head 4.
The pearl screening plant of the present embodiment, also be provided with pearl size screening plant, pearl size screening plant comprises size and divides cribellum 10, size divides cribellum 10 to receive pearl by the conveying trough 9 be communicated with discharging opening 8, size divides cribellum 10 to be fixed on crank and rocker mechanism (two) 11, and crank and rocker mechanism (two) 11 and motor 12 are in transmission connection.
Wherein, motor 12 is equipped with the second bracing frame 22, second bracing frame 22 and is fixedly connected with crank and rocker mechanism (two) 11, to realize to the object of the more stable operation platform of motor 12.
