Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
As shown in Figure 1, corn seed attitude reference device, comprises transmission system, power supply, blower fan 202, airduct 201 and vacuum chamber 2, and vacuum chamber 2 is connected with blower fan 202 by airduct 201; Vacuum chamber 2 is connected and is inhaled kind of a wheel 1 by axle, inhale kind of wheel 1 and be provided with wind hole 104 with the medial surface that vacuum chamber 2 closes on, inhale kind of a periphery for wheel 1 and be provided with plane suction hole 101, plane suction hole 101 is connected by air channel 103 with wind hole 104, and wind control switch or touching switch 102 are located at one end of closing on plane suction hole 101 in air channel 103.Magnetic force ball air channel switch 3 is located at one end of closing on wind hole 104 in wind path wall, and wind control switch or touching switch 102 are controlled the power supply of Magnetic force ball air channel switch 3.The diameter of the little iron ball in Magnetic force ball air channel switch 3 is greater than the diameter in air channel 103.Inhale kind of a side for wheel 1 and be provided with two annular electric conductors, the both positive and negative polarity of power supply is provided with contact chip, contact chip is fixed on vacuum chamber body, annular electric conductor contacts with contact chip, when suction kind of a wheel rotates, contact chip and annular electric conductor continue CONTACT WITH FRICTION, for wind control switch or touching switch and Magnetic force ball air channel switch provide power supply.Described Magnetic force ball air channel switch is comprised of electromagnet and little iron ball.
As shown in Figure 2: in the time need to carrying out orientation to the two ends of corn seed, plane suction hole is for being applicable to the oblong openings of upright corn seed.
As shown in Figure 3: in the time need to carrying out orientation to the different flat horizontal surfaces of corn seed, plane suction hole is circular open, the surrounding at circular open is provided with groove 4.
As shown in Figure 4: the periphery of suction kind of wheel is along being circumferentially with circular groove shape slideway, and circular groove shape slideway and suction kind of a wheel periphery forms circular slideway 5.Circular groove shape slideway and plane suction hole are corresponding, and the end of circular slideway 5 connects Y type slideway 6.Seed porch is provided with locating slot, locating slot with by seed slideway, be connected with simple grain precise seeder 8.Locating slot is divided into vertical locating slot and horizontal locating slot, and vertical locating slot is used for differentiating the flat horizontal surface of seed, and its lower end is lower than the lower end of seed porch; Horizontal locating slot is used for differentiating the two ends of seed.
Circular slideway is provided with three openings, one is seed entrance, in seed porch, be provided with locating slot, locating slot with by seed slideway, be connected with simple grain precise seeder, described seed slideway is the airtight slideway of the various shapes of making according to the width of the flat corn seed of simple grain and thickness; Another two is the outlet of the seed of different flat horizontal surfaces.Seed is brought seed into concentric stroking road after being directed in locating slot and inhaling kind of a wheel and hold.Operation principle directed to seed two ends and different flat horizontal surface orientations is explained respectively below:
1, the orientation of flat horizontal surface and plumule face: because seed has two different flat horizontal surfaces, so illustrate in two kinds of situation.1) when suction kind of a wheel is drawn the seed back side, wind control switch connection magnetic switch power supply, magnetic switch, in on-state, is inhaled kind of a wheel and is rotated after a circle, the little iron ball of magnetic switch can not fall down yet, directed slipping in the Yi Ge branch slideway of Y shape slideway after seed produces vacuum chamber.2) when suction kind of a wheel is drawn seed embryo groove face, wind control switch is subject to the impact that kind of germinal groove leaks out, disconnect magnetic switch power supply, little iron ball in magnetic switch loses its reliss, along with inhaling kind of a rotation for wheel, little iron ball is subject to Action of Gravity Field and falls in air channel, attracted by negative-pressure air power and stop up air channel, the seed that is adsorbed on plane suction hole loses negative pressure suction force, fall down in advance, along circular slideway directional sliding, enter in another branch's slideway of Y shape slideway, while arriving Y shape slideway joint portion, the seed direction of coming is identical with sliding in aforementioned slideway.Meanwhile, wind control switch sets back, and produces after vacuum chamber, because there is no windage, magnetic switch power connection, produces magnetic force, along with inhaling kind of a wheel, be rotated further, little iron ball gravitate enters in magnetic switch and is attracted by magnetic switch again, and the air channel of suction kind of wheel is unimpeded again.
2, the orientation on tip and top: along with inhaling kind of a rotation for wheel, bring seed into concentric stroking road, because seed has two ends, so will illustrate in two kinds of situation: 1) when suction kind of a wheel is drawn seed top, the top of corn seed is inhaled in plane suction hole, because seed top is larger, touch less than touching switch, Magnetic force ball air channel switch is in on-state; Inhale kind of a wheel and rotate after one week, the little iron ball of Magnetic force ball air channel switch can not fall down, and to seed, produces after vacuum chamber, and seed loses vacuum suction and falls down along with inhaling kind of a rotation of taking turns, and that slips into Y shape slideway turns to branch's slideway.To turn to branch's slideway turn to groove place time, seed bottom is blocked by baffle plate, seed gravitate, seed upper end is swung to and is turned to mouthful one side to realize to turn to; 2) when suction kind of a wheel is drawn seed tip, seed is inhaled in plane suction hole, touching switch is encountered at seed tip, the power supply of Magnetic force ball air channel switch is cut off, little iron ball in the switch of Magnetic force ball air channel loses its reliss, along with inhaling kind of a rotation for wheel, little iron ball gravitate is fallen into obstruction air channel in air channel, owing to losing vacuum suction, seed falls down in advance and slips in another branch's slideway of Y shape slideway, while arriving Y shape slideway joint portion, consistent with another branch's slideway seed direction out.Touch switch simultaneously and recover reset condition connection Magnetic force ball air channel switch, along with inhaling being rotated further of kind of wheel, little iron ball gravitate enters again in the switch of Magnetic force ball air channel.
