Abstract
The utility model discloses an air sucking type precise seeding device which consists of a seeding body and a suction fan. The seeding body consists of a body, a seeding plate, a seed mixing plate, a shaft and a seed cup. According to the seeding device, shifting pieces are arranged on the outer sides of seed sucking holes in the seeding plate obliquely; the outer ends of the shifting pieces face towards a rotation direction; an included angle beta between each shifting piece and a center line of the seeding plate is 0-90 DEG; and an isolation trench is communicated with an air outlet of the suction fan by an exhaust duct. According to the seeding device, as the shifting pieces are arranged on the outer sides of the seed sucking holes in the seeding plate, seeds are pushed by the shifting pieces to move towards the center of the seeding plate along the edge of the seeding plate with the rotation of the seeding plate, motion trails of the seeds pass through the seed sucking holes; the negative pressure suction of the seeds is easier and more reliable; voids and lack of the seeds are greatly reduced; the seeding reliability is improved by above 20%; tail air exhausted by the suction fan is used to blow the seeds; and the seeding difficulty caused by seed coating adhesion and the like is avoided.

Summary of the invention
The purpose of this utility model is that the seed tray hole that will solve existing driven sucking precise seeder existence lacks the problem of seed, and a kind of driven sucking precise seeder that can address the above problem is provided.
The utility model is that the sowing body in the existing driven sucking precise seeder is improved.
The utility model is comprised of sowing body and induced-draught fan, the sowing body is by body, seed plate, stir kind of a dish, axle and kind cup consist of, has cannelure on the body, the upper part of cannelure is air-breathing groove, lower part is isolation channel, the outer circumferential side of seed plate offers a plurality of suction holes, seed plate is covered on the cannelure, kind of a dish is fixedly stirred in the seed plate outside, axle passes and stirs kind of dish and seed plate connects with transmission device, plant cup and be positioned at the outside of stirring kind of dish, plant cup and be installed on the body, the inboard of planting cup has interior annular the gear and the outer ring gear, and air-breathing groove is positioned at the annular gear, isolation channel is positioned at the outer ring gear, plant cup and be communicated with the space of stirring kind of dish and the formation of interior annular gear, the suction hole arranged outside on the described seed plate has plectrum, and plectrum is obliquely installed, the outer end of plectrum is towards rotation direction, and the angle β of plectrum and seed plate center line is 0 ° ~ 90 °.
Described isolation channel is communicated with the air outlet of induced-draught fan by exhaust duct.
The beneficial effects of the utility model:
1, the utility model is because the suction hole arranged outside on seed plate has plectrum, rotation along with seed plate, plectrum promotes seed along the seed plate edge to the seed plate central motion, make the movement locus of seed through suction hole, allow the negative pressure suction of seed pick up easier also more reliable, greatly reduce the hole and lack kind of a situation, guaranteed the effect of sowing, sowed Reliability Enhancement more than 20%.
2, the exhaust duct of induced-draught fan is communicated with isolation channel, and the tail wind that utilizes induced-draught fan to discharge blows seed, has avoided the seeding difficulty that causes because of reasons such as kind of clothing agent adhesions.

Embodiment
Consult Fig. 1 to shown in Figure 7, the present embodiment is comprised of sowing body 1 and induced-draught fan 2, sowing body 1 is by body 11, seed plate 12, stir kind of a dish 13, axle 14 and kind cup 15 consist of, has cannelure 16 on the body 11, the upper part of cannelure 16 is air-breathing grooves 161, lower part is isolation channel 162, the outer circumferential side of seed plate 12 offers a plurality of suction holes 121, seed plate 12 is covered on the cannelure 16, kind of a dish 13 is fixedly stirred in seed plate 12 outsides, axle 14 passes and stirs kind dish 13 and seed plate 12 connects with transmission device, kind cup 15 is positioned at and stirs kind of the outside of dish 13, planting cup 15 is installed on the body 11, the inboard of planting cup 15 has interior annular gear 151 and outer ring gear 152, air-breathing groove 161 is positioned at annular gear 151, isolation channel 162 is positioned at outer ring gear 152, planting cup 15 is communicated with the spaces of stirring kind of dish 13 and 151 formation of interior annular gear, suction hole 121 arranged outside on the described seed plate 12 have plectrum 122, plectrum 122 is obliquely installed, the outer end of plectrum 122 is towards rotation direction, and plectrum 122 is 0 ° ~ 90 ° with the angle β of seed plate 12 center lines.
Described isolation channel 162 is communicated with the air outlet of induced-draught fan 2 by exhaust duct 17.
The course of work of the present utility model and principle are:
Consult Fig. 1 to shown in Figure 7, stir kind of dish 13 and seed plate 12 and rotate under the drive of axle 14, induced-draught fan 2 starts air-breathingly simultaneously, and air-breathing groove 161 produces negative pressure, plants seeds in the cup 15 and is adsorbed onto on the suction hole 121 on the seed plate 12.Seed plate 12 is rotated further, and when turning to isolation channel 162 zone, negative pressure disappears, and the seed of suction hole 121 absorption drops in the outer ring gear 152 of kind of cup 15, and discharges from the sowing port 153 of bottom.
