Embodiment
Embodiment 1
The design of present embodiment is applicable to the seeding of smart amount such as rape seed, wheat.
Fill air-sweeping type rape wheat dual-purpose type precise seeder in a kind of, by case 1a1,1a2,1a3, seeding roller 2, seeds protecting plate 4, seed-box 5, grain tube 6, air inlet pipe 9, gas barrier 8a1,8a2, unload kind of mouth 11, discharging tube 13, power transmission shaft 14, drive sprocket 15 and constitute.Said case 1a1,1a2,1a3 and seeding roller 2 are connected to form closed cavity through bolt, and the circular arc dogleg section of seeds protecting plate 5, gas barrier 11a1,11a2 and grain tube 6 terminal opening portions constitute and protect kind of a district 18, fill kind of a district 17, clearly plant district 16 and unload kind of a district 10; Case 1a1,1a2,1a3 adopt bolt to connect as one, and described case 1a1 is provided with balance pore 7, and the junction of case 1a2 and discharging tube 12 is provided with unloads kind of mouth 11.It is inboard that seeds protecting plate 4, gas barrier 8a1,8a2 are welded on case 1a1; Air inlet pipe 9 is welded on the outside of case 1a1.Seeds protecting plate 4 original positions are along the radially bending of seeding roller 2 circular arcs (the circular arc bending of seeds protecting plate design be in order to realize planting clearly function).The end welding of described gas barrier 8a1,8a2 one end and grain tube, the angle between gas barrier 8a1, the 8a2 are 35 degree, and it forms the zone for unloading kind of a district 10.Described kind of the district 10 of unloading is through air inlet pipe 9 and the positive press bond of blower fan.Described case 1a1 is provided with the balance pore 7 of regulating the air chamber flow.Described grain tube 6 passes circular hole place and the case 1a1 welding in the middle of the case 1a1, the end of grain tube 6 and seeding roller 2 matched in clearance.Said drive sprocket 15 and seeding roller 2 are installed in the two ends of power transmission shaft 14 respectively.This seeding roller 2 along the circumferential direction is evenly distributed with type hole 3, and seeding roller 2 is a matched in clearance with case 1a1,1a2,1a3, seeds protecting plate 4, gas barrier 8a1,8a2.
Operation principle of the present invention is: in to fill air-sweeping type rape wheat dual-purpose type precise seeder be that basic principle is filled kind with the filling space, utilize gravity and pressure differential seeding and prevent that the type hole from blocking.
Shown in accompanying drawing 3; During work, drive sprocket 16 drives seeding rollers 2 and rotates, when seeding roller 2 turns to when filling kind of district 18; Seed is got into through grain tube 6 terminal openings by seed-box 5 and fills kind of a district 18; And under self gravitation, centrifugal force and the interphase interaction of kind sub-group, charging into type hole 3, grain tube 6 ends not opening portion can prevent that seed is slipped to and protect kind district 19 that the aperture size of grain tube 6 end openings part can be controlled and fill kind of the 18 kinds of subgroup height in district.When seeding roller 2 turns to clearly when planting district 17; The seed that does not charge into type hole 3 falls back under the barrier effect of action of gravity and seeds protecting plate 4 circular arc dogleg section and fills in kind of the district 18; Charging into seed in the type hole 3 forwards to unload with seeding roller 2 down in seeds protecting plate 4 protections and kind distinguishes 10; Barotropic gas unloads kind of a district 10 through air inlet pipe 9 inputs, makes to unload kind of district 10 and unload kind of mouth 11 places to have pressure differential, and then seed receives the comprehensive function of gravity, centrifugal force and air-blowing power to enter discharging tube 12 uniformly in unloading kind of district 10; Accomplish the seeding operation;, unload kind of district's 10 gas pressures therebetween, guarantee to unload kind of the uniformity of district's 10 internal pressures through balance pore 7 (diameter of the balance pore of present embodiment is 4-6mm) adjusting.
