Detailed description of the invention
The present invention is further illustrated below in conjunction with the accompanying drawings:
As shown in Figure 1, Figure 2, Figure 3 shows, patent one Oryza sativa L. precision drill of the present invention: include the flat field deck of boat 1, frame 2, Position Scale 3, traction frame 4, drum type intensive rate dibble sowing implement 5, power transmission shaft 6 and drive land wheel 7.Traction frame 4 one end is fixedly installed on before frame 2, traction frame 4 other end stationary positioned scale 3, is fixedly installed the flat field deck of boat 1 below frame 2, frame 2 with on drum type intensive rate dibble sowing implement 5 phase connecting shaft.
Patent one Oryza sativa L. precision drill traction frame 4 leading portion of the present invention can couple Mechanical Driven or manpower drives, and be provided with perpendicular positioning scale 3, traction frame 4 other end is fixed in frame 2, the flat field deck of boat 1 is fixed in frame 2 lower end, frame 2 other end is coupled with driving land wheel 7 by rotating shaft, land wheel is driven to be symmetrically installed one on one side, several drum type intensive rate dibble sowing implements 5 are secured side by side in rotary shaft 6, having feed outlet by spacing in the rows requirement work on the annulus of the left and right Sheng kind bowl of Drum-type precision seeder 5, in two rings, exit orifice forms feed outlet when fastening.
As shown in Fig. 4, Fig. 5, quantitative loop 505 has unique feed outlet, seeding quantitative loop 505 to fix with frame, and drum-type feed mechanism for seed 5 regulates line-spacing and is fixed in rotary shaft 6, the seeding when the feed outlet on drum-type feed mechanism for seed 5 annulus overlaps with the feed outlet of quantitative loop；The feed outlet bottom of simultaneous quantitative ring 505 is additionally provided with sowing port 504, and the bottom of the feed outlet of quantitative loop 505 can also be provided with the flow rate regulation door 503 for controlling seed discharge capacity.
A kind of modification as the present invention, feed outlet on the annulus of the left and right Sheng kind bowl of the present invention can be arranged to different identical hole counts, may also set up different hole counts or multiple, when left and right Sheng kind bowl feed outlet coupling one on drum-type feed mechanism for seed 5, regulation correspondence hole count reaches to control the purpose of strain number.
Another kind of modification as the present invention, feed outlet on the annulus of the left and right Sheng kind bowl of the present invention can be arranged respectively to the annular feed outlet of more than two row, the feed outlet of the most each row is identical or different or equimultiple, control often wheel seeding hole number, so the flow rate difference for different plants when being overlapped by the annular feed outlet of different row on the left and right annulus containing kind of bowl and determine often wheel seeding hole number.
Right kind bowl is provided with dress kind mouth 501 and capping on having.
By the some equidistant feed outlet of spacing in the rows requirement on the ring of drum-type feed mechanism for seed 5 garden.
Quantitative loop 505 forms 30 ° with vertical aspect below unique feed outlet, sows when coupling one with the feed outlet of drum-type feed mechanism for seed 5.
