Embodiment

Consult Fig. 1,3,4,5,6,7.Rotating shaft 5 is supported in the housing 1 by rolling bearing 14 rotations, and inoculation dish 3 is arranged in the housing chamber of coupling setting and is fixed on the rotating shaft 5.The uniform inoculation of the card outer rim of inoculation dish 3 hole 6, claw plate 2 is fixed on the inoculation dish 3 by bolt 15, and the cavity between its outer card and the end cap 7 is a storage bin 8.Separator disc 4 between inoculation dish 3 and claw plate 2, be fixed in the round seam 19 that coupling is provided with on the shell wall of housing 1 and and prevent its rotation by stop pin 20.The card of separator disc 4 covers the card of inoculation dish 3, and inoculation hole 6 can obtain the part by the seed inlet 9 of separator disc 4 tops and appear.The circumferential length of seed inlet 9 is decided on seeding quantity, is advisable to manifest 2～3 inoculation holes 6 usually.Claw plate 2 has equally distributed pusher dog 10, the external end head of pusher dog is greater than the lower edge of seed inlet 9 (figure acceptance of the bid lead-in wire guides point to be the lower edge), less than the outer rim of inoculation dish 3, promptly in seed inlet 9 lower edges between the outer rim of inoculation dish 3, be equipped with the spoon hole 11 that tilts to inoculation hole 6 on the external end head of each pusher dog 10, the concrete shape in spoon hole 11, size are by seed 17 couplings of being broadcast.There is the bottom of feed pipe 13, housing 1 that sowing port 12 is arranged on the charging aperture of end cap 7, the arc length of sowing port and seed inlet 9 couplings.

Still consult Fig. 1,3,4,5,6,7.The utility model is placed in suitable position on the sower.During bunch planting, in storage bin 8, pour into a certain amount of seed by feed pipe 13, transmission device on rotating shaft 5 and the sower is in transmission connection, rotating shaft 5 drives inoculation dish 3, claw plate 2 rotates synchronously, when rotating to the below, dials by each pusher dog 10 seed of scraping in the storage bin 8, the external end head of each pusher dog 10 is at seed inlet 9 places that do not rotate to above the separator disc 4, spoon hole 11 on it is subjected to the isolation of separator disc, not corresponding with inoculation hole 6, at this moment, form the container cavity that can only hold a routine seed between spoon hole 11 and the separator disc 4, a seed enters in the spoon hole 11; When the external end head of pusher dog 10 rotates up seed inlet 9 places, spoon hole 11 and inoculation hole 6 corresponding communicating, seed 17 is slipped in the inoculation hole 6 by the spoon hole 11 that tilts under action of gravity, after charging aperture 9 is left with the rotation of inoculation dish 3 in inoculation hole 6, seed in it is separated dish 4 and is enclosed in the inoculation hole 6, discharge by sowing port 12 when cheating sowing port 12 places that rotate to housing 1 bottom, finish the accurate quantification bunch planting with inoculation.

In the utility model, the quantity in inoculation hole 6 is 1 or 1/2 times of claw plate 2 upper poking claws 10 quantity, specifically decides on the requirement of seeding quantity.In the enforcement 1 shown in Fig. 1,3,4,5,6,7, the quantity in inoculation hole 6 is 1 times of pusher dog 10 quantity, and the two is all 12, and pusher dog 10 is corresponding one by one with inoculation hole 6, and when seed inlet 9 place's correspondences communicated, inoculation hole 6 received a seed at every turn; In Fig. 2,8 illustrated

embodiments

2,1/2 times of quantity pusher dog 10 quantity in inoculation hole 6, promptly pusher dog 10 is 12, inoculation hole 6 is 6, at this moment, per two pusher dogs, 10 corresponding inoculation hole 6, two pusher dogs 10 are cheated 6 o'clock inoculation holes in the inoculation of seed inlet 9 corresponding growths and are received two seeds.

Consult Fig. 1.16 is connecting plate when sower is installed among the figure, is the ennation of housing 1.In the illustrated

embodiment

1,2, the external diameter of housing 1 can be divided into large, medium and small plurality of specifications series of products between 150mm to 300mm.
