The gas blowout trigger switch of described gas injection controller 21 is controlled by control system 2, described spray kind device nozzle 12 is ejected into the electric gas nozzle of sowing in the soil one by one for rotating and will plant the seeds of being held by described elasticity supporting spring in the nest 10 in the gas blowout mode with seed plate 4, the puff prot of described spray kind device nozzle 12 and the kind nest 10 that rotates to its below over against; Described spray kind device nozzle 12 is fixedly mounted on the external shell 1.
Described detecting unit 11 comprises the velocity sensor 20 that the pace of drawing the tractor that described sower advances is detected in real time, and the kind nest 10 that rotates under spray kind of the device nozzle 12 is promptly sprayed in the previous of all nests and all nests of described spray or two kind nests 10 whether lack kind of a scarce kind of detecting sensor 15 that detects simultaneously.The quantity of described scarce kind of detecting sensor 15 is two or three.
In the present embodiment, the quantity of described scarce kind of detecting sensor 15 is two, one is installed in spray kind of device nozzle 12 sidepieces, another be positioned at previous kind of nest 10 of all nests of described spray directly over and its be installed on spray kind of device nozzle 12 or the external shell 1 by fixture.Described velocity sensor 20 specifically is installed on the described tractor.
Described control system 2 is for according to the velocity sensor 20 real-time tractor paces that detect, and tackles driving mechanism 5 and gas injection controller 21 mutually and controls and make the rotating speed of seed plate 4 and the spray kind speed and the described tractor pace of spray kind of device nozzle 12 be complementary; And according to lacking kind of detecting sensor 15 detected scarce kind of signals, correspondingly make the complex control system that seed plate 4 fast rotational to a kind of nest 10 or control Alarm Unit 3 down alarmed by control driving mechanism 5.
In the present embodiment, described driving mechanism 5 is for being installed in the drive motors on the external shell 1, and the power take-off 17 of described drive motors is vertical driving shaft, and described vertical driving shaft bottom is fixedly mounted on seed plate 4 upper center.Be connected by transmission mechanism 18 between the driving shaft of described power take-off 17 and agitator 7.Described transmission mechanism 18 is the transmission mechanism of being made up of two gears.
The course of work of the present utility model is: at first, (stirring the seed that seeds can effectively prevent seed-box 6 by agitator 7 is maked somebody a mere figurehead) falls to the seed of seed-box 6 on the seed plate 4 one by one under the seed-box 6 that the is positioned at seed plate 4 tops prolonged agitation effect of agitator that portion installs 7 within it; Afterwards, carry out the precision ordering by 4 pairs of seeds that fall from seed-box 6 of kind of nest formula seed plate, specifically be owing to along the circumferential direction be provided with the kind nest 10 that a cycle basis instinct is held a seed on the seed plate 4, and brush 8 by the clear kind that install seed plate 4 tops, continuous rotation along with seed plate 4, the seed that falls on the seed plate 4 is swept into the empty nest 10 of planting successively, that is to say, owing to plant in the nest 10 and can only hold a seed, thereby after a seed entered kind of nest 10, other seed is along with the rotation of seed plate 4 will be swept to next the kind in the nest 10 and carries out seeding by the clear brush 8 of planting, simultaneously seed-box 6 bottoms go out kind of the mouth outside and also are provided with and prevent the seed retaining plate 16 that rolls from the seed that seed-box 6 falls everywhere, to sum up, seed plate 4 seeding speed are very fast.In addition, for guarantee to enter in kind of the nest 10 seed do not rotate to spray kind of device nozzle 12 under during i.e. spray kind of position, for avoiding seed because owing to conduct oneself with dignity, collide or shake situation former thereby that fall voluntarily, promptly leak kind of a situation, in various nests 10, be provided with the profile of tooth rubber supporting spring 19 that seed is temporarily stopped, profile of tooth rubber supporting spring 19 is being held seed and is being made seed be unlikely to free-falling or because of being collided and when reason such as vibration falls in the soil, also can not causing any damage to seed.Only be rotated the seed to the kind nest 10 of spray kind of position, just under the jet-action of spray kind of the gases at high pressure that device nozzle 12 is ejected, break through stopping of profile of tooth rubber supporting spring 19, fall in the soil, finish sowing with higher speed.Described spray kind device nozzle 12 utilizes different gas pressures that seed is directly injected to the soil from seed plate 4, and the gas pressure of spray kind of device nozzle 12 when spray kind, injection direction etc. can be regulated, this is because the gas pressure during spray kind of device nozzle 12 sprays kind, injection direction etc., correspondingly can to seed land speed, land the time, land angle, spring etc. after landing and produce corresponding influence.
In the seeding process, if after not having seed to enter corresponding kind of nest 10 promptly to take place to lack kind or take place to leak kind, kind of a phenomenon then can appear lacking, thereby influence seeding quality, 15 of scarce kind of detecting sensors in the detecting unit 11 can detect and lack kind of a phenomenon at this moment, and synchronously detected scarce kind of information synchronization are sent to control system 2.Described control system 2 is at first analyzed the scarce kind of information that is received, when having only scarce kind of detecting sensor 15 to the kind nest 10 that is positioned at spray kind of position to detect to lack kind information, then 2 of control systems make it drive seed plate 4 quick rotation by control driving mechanism 5, make 12 pairs at spray kind of device nozzle lack the kind nest 10 of planting simultaneously and do not spray kind of an operation, spray kind of an operation in the time of under the kind nest 10 that the next one is equipped with seed turns to spray kind of device nozzle 12 again, the rotating speed of seed plate 4 also recovers normally afterwards, equates to guarantee the sowing spacing in the rows; And lack kind of detecting sensors 15 and detect and be when lacking kind when two, then control system 2 control Alarm Units 3 carry out alarm.In addition, because the spray kind device nozzle 12 of described a plurality of seedings/spray kind of device is controlled by independent gas injection controller 21 respectively, and each seeding unit is respectively by independently control system 2 and driving mechanism 5 are controlled and driven, avoiding all seedings/spray kind of device to lack kind of back and influence the situation of spacing in the rows at certain seeding/spray kind of device at seeding time, and when certain seeding/spray kind the device appearance is scarce also can not influence the normal seeding operation that device is planted in other seeding/spray when planting.
Simultaneously, in the seeding operation process, the spray kind speed of spray kind of device nozzle 12 and the rotating speed of seed plate 4 must be complementary with the tractor pace, no matter thereby tractor seeding operation speed be how the tractor pace changes, can guarantee that all the seed spacing in the rows of being sowed is equal.
The above; it only is preferred embodiment of the present utility model; be not that the utility model is imposed any restrictions; everyly any simple modification that above embodiment did, change and equivalent structure are changed, all still belong in the protection domain of technical solutions of the utility model according to the utility model technical spirit.
