Description
Technical field
The utility model relates to a kind of implanted device, a kind of specifically pneumatic type precise seeder.
Background technology
The pneumatic type seeding unit that the granule seed sowing machine uses at present, seed plate is installed between air chamber and the case, open even recess hole on the seed plate and inhale kind, seeding, this pneumatic type seeding unit complex structure, adopt the seed plate of recess hole structure, course of work further groove pore volume is many seeds of absorption easily, cause replay, during the recess hole absorbed seed, may cause the seed breakage, damaged seed stops up recess hole easily, causes broadcast leakage, and is very inconvenient to the adjusting of spacing in the rows in the seeding unit sowing process of this structure in addition.
Summary of the invention
The purpose of this utility model is in order to solve the problems of the technologies described above, to provide a kind of simple in structure, can smartly measure seeding, effectively reducing seed breakage and broadcast leakage problem and take place, and conveniently regulate the pneumatic type precise seeder of spacing in the rows.
Technical scheme comprises the seed plate that is actively socketed on the stator center, be provided with airtight zone of positive pressure in the described stator, space between seed plate and the stator forms airtight negative pressuren zone, also be provided with corresponding with zone of positive pressure and negative pressuren zone respectively pore on the described stator, described seed plate perimembranous evenly is provided with a plurality of slots that are fitted with nozzle that can be communicated with zone of positive pressure and negative pressuren zone respectively, and described nozzle end has inhales kind of a mouth.
Described seed plate is through the column pivot bush unit of bearing and stator center.
Described suction kind mouth is positioned at the nozzle end side.
Described suction kind mouth is the circular opening of aperture less than the seed path length.
With the corresponding pivot bush unit in seed plate center with stator center, between seed plate and stator, form the zone of positive pressure and the negative pressuren zone of sealing, each corresponding pore that is located on the stator of described zone of positive pressure and negative pressuren zone, be used for ventilation or suction air to form local malleation or negative pressure, can utilize the better seeding of gravity of seed self.Be fitted with nozzle on the slot that described seed plate perimembranous evenly is provided with, nozzle end has inhales kind of a mouth.Seed plate is driven and can rotates around stator center, and nozzle is rotated through slot thereupon, just is communicated with negative pressuren zone when through negative pressuren zone; When going to zone of positive pressure, then be communicated with, thereby nozzle interior forms corresponding negative pressure or barotropic state with zone of positive pressure.
Described seed plate is through the column pivot bush unit at bearing and plenum chamber center, and during rotation, seed plate is that rotate at the center with the column.The slot of described seed plate perimembranous can evenly be provided with a plurality of, and the quantity of slot can require to set in advance according to spacing in the rows, as 3,4,6,12 or the like.Described nozzle is inserted in the slot, and can dismantle as required.Inhaling kind of size in the aperture of mouth and number on the described nozzle can change according to the needs of sowing seed and quantity.For avoiding the negative-pressure adsorption kind period of the day from 11 p.m. to 1 a.m, may cause seed breakage or seed to stop up, the aperture of inhaling kind mouthful should be less than the path length of (preferably being slightly smaller than) seed, and each is inhaled kind mouthful can just in time adsorb a seed and seed is bled in the hole, thus the problem of also having avoided adsorbing many seeds.
The utility model is simple in structure, easy to use, rotate by seed plate, make and form negative pressure or barotropic state in the nozzle, thereby finish the purpose of absorbed seed and seeding, can smartly measure seeding, effectively reduce seed breakage and broadcast leakage problem and take place, and the convenient spacing in the rows of regulating, the precision drilling of small-sized seed in being specially adapted to.

Embodiment
Below in conjunction with accompanying drawing the utility model is further explained explanation:
With reference to accompanying drawing, seed plate 1 is by column 7 pivot bush units of bearing 2 with stator 4 centers, be provided with airtight zone of positive pressure 5 in the described stator 4, space between seed plate 1 and the stator 4 forms airtight negative pressuren zone 5, go back corresponding two pores 6 that are communicated with zone of positive pressure 8 and negative pressuren zone 5 respectively that are provided with on the described stator 4, the perimembranous of described seed plate 1 evenly is provided with a plurality of 12 slots 10 that can be communicated with zone of positive pressure 8 and negative pressuren zone 5 respectively and (is each slot 10 when rotating or is in the state that is communicated with zone of positive pressure 8, or be in the state that is communicated with negative pressuren zone 5), be fitted with nozzle 3 on the described slot 10, the end profile of nozzle 3 has circular kind of the mouth 9 of inhaling, and the aperture of described suction kind mouth 9 is less than the path length of seed.
Operation principle:
The utility model can utilize the actuator drives seed plate 1 on the sower to rotate around column 7, and velocity of rotation can be regulated by sprocket ratio, and stator 4 can be fixedly mounted on holding on kind of the case of sower.During rotation, when nozzle 3 is driven, when turning to the position corresponding with negative pressuren zone 5, respective nozzles 3, slot 10, negative pressuren zone 5 are communicated with, and form negative pressure in the nozzle 3, seed is adsorbed in kind of mouth 9 places and carries seed be rotated further by inhaling kind mouthfuls 9; When nozzle 3 went to the position of corresponding zone of positive pressure 8, respective nozzles 3, slot 10, zone of positive pressure 8 were communicated with, and form malleation in the nozzle 3, and seed relies on air pressure and gravity to deviate from, and reaches the purpose of seeding.
When needs increase spacing in the rows, optionally the nozzle in the part slot 10 3 is taken off, and block, evenly be reduced to 6 as making 12 nozzles 3 in original slot 10 with plug, and then change under the situation of structure not needing, reach the purpose of regulating spacing in the rows.
Positive and negative air pressure of the present utility model can provide by the positive and negative air-pressure working cell on the sower (as vavuum pump etc.) through corresponding pore 6.
