Embodiment

Pneumatic drum type rice growing device comprises frame 1, end cap 2, cylinder 3, inhales blow gun 4, seal diaphragm 5, mozzle 6, inhale kind in pipe 7, blow kind of flexible pipe 8, bearing 9, drum gear 10, inhale kind of a flexible pipe 11, on plant case 12, shaft 13, the case 14 of sowing, seed 15, stir gear 16, sprocket wheel 17; Inhale kind of an interior pipe 7, the case 14 of sowing is fixed on the frame 1, last kind of case 12 is nested on the case 14 of sowing, case 14 tops of sowing are provided with shaft 13, shaft 13 by bearing fixing on frame 1, shaft 13 1 ends are equipped with and stir gear 16 and sprocket wheel 17, evenly install vertically and radially on the cylinder 3 and inhale blow gun 4, cylinder 3 two ends and end cap 2 are rigidly connected, wherein the end cap 2 of a side and drum gear 10 are connected by bolt, drum gear 10 is meshed with stirring gear 16, end cap 2 interior installation bearings 9 are also planted an interior pipe with suction and are matched, pipe 7 downsides are provided with the v-seal chamber that is divided into by two seal diaphragms 5 in the suction kind in the cylinder, mozzle 6 be installed in the v-seal chamber that two seal diaphragms 5 are divided into and with blow kind of flexible pipe 8 and be connected.

Described suction blow gun is whenever to arrange to put 18-24 in 9 cun scopes axially effectively sowing fabric width, inhales blow gun and is connected with cylinder inside.The part tube wall of inhaling between kind of the two end cap of interior pipe 7 is provided with a plurality of holes, and the hole is connected with cylinder inside.

The course of work of the present utility model: start negative-pressure air fan, the air compressor of whole raising rice seedlings production line, pipe 7 is connected the certain vacuum of generations in the cylinder 3 with negative-pressure air fan in the suction kind of pneumatic drum type rice growing device.Mozzle 6 connects compressed air by blowing kind of flexible pipe 8, and compressed air enters seal diaphragm 5 and the space that cylinder 3 forms through mozzle 6, makes to be malleation in this space.Start pneumatic drum type rice industrial sprout cultivation planter drive motor, and with on the sprocket wheel 17 of transmission of power to the shaft 13, drive shaft 13, stirring gear 16 rotate synchronously, stir gear 16 and drive drum gears 10 rotations, 3 rotations of drum gear 10 drive cylinders.Under shaft 13 turning efforts, the rice paddy seeds 15 in the case 14 of sowing enter the space of sow 3 on case 14 bottoms and cylinder.Because have certain vacuum in the cylinder 3, suction blow gun 4 heads of cylinder 3 negative pressuren zones are negative pressure, along with the rotation of cylinder 3, rice paddy seed 15 of suction blow gun 4 absorption that cylinder 3 negative pressuren zones contact with seed 15, and with inhaling blow gun 4 rotations.When suction blow gun 4 goes to the zone of positive pressure of seal diaphragm 5 belows with cylinder 3, make suction blow gun 4 heads also be malleation, the seed 15 that inhale blow gun 4 on the same row of cylinder 3 axial directions this moment falls simultaneously, and fall in the seedling dish that moves the below, cylinder 3 each row inhale when blow gun 4 goes to this position the seed 15 of absorption are fallen.The suction blow gun of no absorbed seed 15 rotates with cylinder 3, turn over the zone that cooperates with seal diaphragm 5 when cylinder 3 after, the suction blow gun 4 on the cylinder is absorbed seed 15 once more, repeats said process, finishes air-sucking type and sows process.By regulating the rotating speed that drives variable-speed motor, realize the adjustment of seeding quantity.
