In conjunction with Figure 11 and Figure 14; Said auxiliary seed-dropping equipment is an electromagnetic actuator 12; Said electromagnetic actuator 12 comprises electromagnetic actuator shell 12-1 and the expansion link 12-2 that can stretch out or withdraw from electromagnetic actuator shell 12-1; Be provided with in the said electromagnetic actuator shell 12-1 coil rack 12-3 and winding on coil rack 12-3 and with the electromagnetic actuator shell 12-1 inwall coil 12-4 of clamping mutually; Said coil rack 12-3 both ends open inner hollow; The end of said expansion link 12-2 stretches into the inside of electromagnetic actuator shell 12-1 and can extend to coil rack 12-3 inner, and the other end of said expansion link 12-2 passes said cover plate 1-2, and said expansion link 12-2 is with suitable near suction kind mouth two 3-5 of seed plate 3 lowest orders; Said expansion link 12-2 goes up and is positioned at electromagnetic actuator shell 12-1 and is provided with baffle plate two 12-6 that compress spring 12-5 and processed by magnetic material; The side that said coil rack 12-3 goes up near baffle plate two 12-6 is connected with the backplate 12-7 that has through hole two, and the end of said compression spring 12-5 is connected with baffle plate two 12-6, and the other end of said compression spring 12-5 is connected with backplate 12-7; Said monitor control system also comprises the relay 11 that is used for control coil 12-4 energising or outage, and said relay 11 joins with the output of controller 14, and said coil 12-4 joins through relay 11 and power supply 15.
In the present embodiment, when this was used for the air-suction seeding unit work of sower, air exhauster was started working; Air gets into and gets in the capping apparatus 2 from the gap between seed plate 3 and the housing 1-1 from air inlet 4-1, and then gets into air exhauster with the discharge pipe 1 that is connected with air outlet one 2-4 and through air outlet two 2-8 with the discharge pipe that is connected with air port two 2-8 2 10 through air outlet one 2-4, and said discharge pipe 2 10 is connected with discharge pipe 1 through three-way connection 7-1; Thereby in seed-taking device 1 and capping apparatus 2, form negative pressure, so, grain planted through seed input pipe 4 entering seed-taking devices 1; And in seed-taking device 1, be adsorbed on kind of a mouthful 3-2 under the action of negative pressure and inhale on kind of mouthful two 3-5; Seed plate 3 rotates counterclockwise under the drive of motor 5, when suction kind mouth one 3-2 that is adsorbed with kind of grain turns to the lowest order of seed plate 3, at this moment; Owing to be arranged on the existence of the piece 2-3 that keeps out the wind between coaming plate one 2-1 and coaming plate two 2-7; Make that air cavity two 2-10 between coaming plate one 2-1 and coaming plate two 2-7 are intercepted, disappear thereby make in the seed-taking device 1 and be positioned at kind of the subnormal ambient of mouth 1-3 top, at this moment; The kind grain that is adsorbed on kind of mouthful 3-2 comes off from inhaling kind of a mouthful 3-2 under the effect of gravity; And drop from going out kind of a mouth 1-3, accomplish sowing, simultaneously; Because air cavity one 2-9 connects, the kind grain on said suction kind mouth two 3-5 can not drop under action of negative pressure and rotate with seed plate 3.Present embodiment is through being provided with electromagnetic actuator 12 as auxiliary seed-dropping equipment; Make when suction kind of a mouthful 3-2 upward occurs adsorbing the situation of kind of grain; The kind grain that will be adsorbed on kind on mouthful two 3-5 through the expansion link 12-2 on the electromagnetic actuator 12 peels off, and makes this kind grain overcome in the seed-taking device 1 negative pressure and then fall from going out kind of mouth 1-3, can in time reseed under the situation of broadcast leakage being about to occur; When on inhaling kind of a mouthful 3-2, all being adsorbed with kind of grain; At this moment, said expansion link 12-2 withdrawal, the kind grain that is adsorbed on kind of mouthful two 3-5 rotates with seed plate 3.Make the broadcast leakage phenomenon of this seeding unit almost can be able to stop through electromagnetic actuator 12 is set, sowing efficient further improves.In addition, also can adopt hydraulic cylinder or hydraulic jack to use as auxiliary seed-dropping equipment.
In the present embodiment, the normality of said electromagnetic actuator 12 is: thus said controller 14 control relays 11 make power supply 15 and coil 12-4 keep connected state, and the magnetic force that coil 12-4 energising produces makes expansion link 12-2 keep retracted state through baffle plate two 12-6; Said monitor control system in use, radiating portion 6-1 and the receiving unit 6-2 of said controller 14 control correlation photoelectric sensors 6 carry out work, when on inhaling kind of mouth one 3-2, being adsorbed with kind of grain; Owing to plant the obstruct of grain; Receiving unit 6-2 can't receive the photosignal that radiating portion 6-1 launches, still, and when grain is planted in absorption on inhaling kind of a mouthful 3-2; At this moment; Receiving unit 6-2 can receive the photosignal of radiating portion 6-1 emission, and controller 14 control relays 11 break off, thereby make power supply 15 stop the power supply for coil 12-4; This moment, expansion link 12-2 ejected under the spring force effect of compression spring 12-5, thereby the kind grain that will inhale on kind of mouthful two 3-5 is dialled.
As shown in Figure 8; Said kind grain is deposited plate 9 and is comprised horizontal segment 9-1 that is arranged on seed inlet 1-5 below and the arc section 9-2 that is used to prevent that kind of grain from dropping from said horizontal segment 9-1; The end of said horizontal segment 9-1 is connected with housing 1-1 inwall; The end of said arc section 9-2 is connected with the other end of horizontal segment 9-1, has suction kind mouth one 3-2 that supplies seed adjustment sheet one 3-1 and seed adjustment sheet two 3-4 and be adsorbed with kind of grain between the other end of said arc section 9-2 and the housing 1-1 inwall top and plants the gap that mouthful two 3-5 pass through with inhaling.
As shown in Figure 8; A plurality of said suction kind mouth one 3-2 all evenly lay around the center of seed plate 3; Evenly be provided with on the said seed plate 3 and around the center of seed plate 3 to be used to stir and be positioned at kind of grain and deposit on the plate 9 seed adjustment sheet one 3-1 and a plurality of seed adjustment sheet two 3-4 that plant grain; A plurality of said seed adjustment sheet one 3-1 all are positioned at the inboard of a plurality of suction kind mouth one 3-2; A plurality of said suction kind mouth two 3-5 all are positioned at the inboard of a plurality of seed adjustment sheet one 3-1; A plurality of said seed adjustment sheet two 3-4 all are positioned at the inboard of a plurality of suction kind mouth two 3-5, and said horizontal segment 9-1 goes up and is provided with near the side of seed plate 3 and supplies seed adjustment sheet one 3-1 breach one 9-3 that passes through and breach two 9-4 that supply seed adjustment sheet two 3-4 to pass through, and has suction kind mouth one 3-2 that supplies seed adjustment sheet one 3-1 and seed adjustment sheet two 3-4 and be adsorbed with kind of grain between the upper end of said arc section 9-2 and the housing 1-1 inwall top and plants the gap that mouth two 3-5 pass through with inhaling.
