Single seed is caught has seed to catch hole 13 on the sheet 9; Catch hole 13 upper sheds and be slightly less than under shed; Seed particle diameter maximum is a bit larger tham in upper shed, and the degree of depth is greater than 1/2 of general seed particle diameter, to guarantee all to have one and only have the seed hole 13 that is captured and catch at every turn.
Single seed is caught sheet 9 and is installed in single seed and catches on the sheet installing handle 8, and can catch sheet slideway 10 along single seed and move freely; Single seed is caught sheet installing handle 8 and is connected with handle 7, and snap ring A15 and single seed are caught between the sheet installing handle 8 spring A14 is housed; Single seed limit bridge 11 is caught on sheet slideway 10 paths at single seed, and has covered seed small opening 5.Single seed limit bridge 11 is the pipeline configuration of a hollow, at an end of catching sheet 9 near single seed opening is arranged, and opening part has a limit for height layer, and the height that the limit for height layer is caught sheet 9 apart from single seed is about 1/2 of general seed particle diameter.Because the degree of depth of catching hole 13 is greater than 1/2 of general seed particle diameter, thus the single seed that catch in the hole 13 that is captured expose single seed catch the height of sheet 9 will be less than 1/2 of general seed particle diameter, so can be smoothly through single seed limit bridge 11.And the height that the limit for height layer is caught sheet 9 apart from single seed is not enough to get the accuracy of a seed through other seeds of catching at large so guaranteed each direct election more.
When pressing pressuring press handle 7, drive single seed seizure sheet 9 and move ahead, and spring A14 stops compression because of receiving snap ring A15.According to the setting of above-mentioned seizure hole 13 sizes, can only there be a round shaped grain seed to catch to get in sheet 9 motion processes in the reservoir 1 and catches in the hole 13 at single seed.Single seed is caught when being advanced into single seed limit bridge 11 before sheet 9 continues; Because single seed limit bridge 11 and single seed are caught the limitation in height between the sheet 9; The result has only a seed of catching in the hole 13 through single seed limit bridge 11, and all the other seeds are limit bridge to intercept.Certain position to be pressed into is caught hole 13 and just in time is in fistulae 4 tops, and seed falls from seed small opening 5, gets into fistulae 4 and sows.Behind the loosening handle 7, handle 7 drives and catches the sheet return-to-home position under the effect of spring A14 elastic force.
Be to satisfy the vary in size demand of big seedlet of sowing, be installed in single seed catch single seed on the sheet installing handle 8 catch sheet 9 can dismounting and change, the high-rise height of single seed limit bridge 11 upper limits can be regulated.
Inner for preventing that seeder from inserting matrix; Matrix gets into seed fistulae 4 and stops up the normal use of planting subchannel and influencing seeder; Anti-blocking design is adopted in present embodiment fistulae 4 bottoms: specifically be made up of fistulae 4, spring B 20, snap ring B17, egative film 18 and pressure sensitive pin 19, fistulae 4 bottoms are front fine and rear thick, and snap ring is enclosed within fistulae 4 bottoms; Can move up and down, be connected with pressure sensitive pin 19 below the snap ring; Snap ring also has egative film 18 down, and egative film 18 is fixed in the holding rod 3, but the aperture that has voltage supply power inductive needle 19 to pass on the egative film 18; Spring B 20 is arranged above the snap ring, and spring B 20 is pressed in snap ring B17 on the egative film 18, and the other end of spring B 20 is fixed in the holding rod 3.
During sowing, in advance seeder is inserted matrix.In this process, pressure sensitive pin 19 contacting substrate the earliest receives upward pressure, because egative film 18 is fixing, inductive needle passes the connected movable snap ring B17 of egative film 18 drives and moves up, and spring B 20 receives force compresses.And fistulae 4 heads are front fine and rear thick, and snap ring B17 moves up and causes fistulae hole fully closed (shown in Fig. 5-A).Like this, guaranteed that fistulae 4 is in closure state when inserting matrix.Treat that by pressuring press handle 7, seed is carried on the seeder after falling into fistulae 4, pressure sensitive pin (19) pressure disappears, and spring B 20 elastic force promote snap ring B17 and move down, and original size is recovered in the fistulae hole, and seed is promptly broadcast matrix (shown in Fig. 5-B).
The present invention designs and has guaranteed that whole process mesostroma can not get into the inner obstruction of fistulae, has avoided matrix to stop up the problem of kind of subchannel.Adopt the design of anti-caulking tube to avoid matrix to stop up the problem of kind of subchannel, increased the stability of seeding operation.
The above only is a preferred implementation of the present invention; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from know-why of the present invention; Can also make some improvement and replacement, these improvement and replacement also should be regarded as protection scope of the present invention.
