Specific embodiment

The improvement details being further illustrated below in the present embodiment.See Fig. 2, the cylindrical circumferential wall 33 in the present embodiment by The arc 331 of six pieces of deciles is spliced to form successively, the most square in the inner side of the first housing 31 and the second housing 32 To being provided with cannelure (cannelure is the most not shown), the dual-side of arc 331 lays respectively at the cannelure of the first housing 31 With in the cannelure of the second housing 32, each arc 331 is just clamped by such first housing 31 and the second housing 32, sees Fig. 4, the first housing 31 is provided with 16 arc installing holes 311, and wherein 1 arc installing hole 311 is for sharing installing hole, its Include that sharing installing hole has 5 arc installing holes 311 to be circumferentially evenly distributed interior, exists including shared installing hole Inside there are 6 arc installing holes 311 to be circumferentially evenly distributed, have 7 arcs to install including shared installing hole interior Hole 311 is circumferentially evenly distributed (owing to five deciles, six deciles, three kinds of uniform holes of seven deciles all share a hole, so arc A total of 5+6+7-2 of plate installing hole, i.e. 16), the second housing 32 is provided with 16 arc installing holes, each arc the most accordingly Be respectively connected with shank (shank is the most not shown) on shape plate 331 in both sides, each shank is inserted in arc the most accordingly and installs In hole 311, in the present embodiment, owing to arc 331 is six pieces, thus the shank of six pieces of arcs to be inserted into six deciles uniform In arc installing hole, in order to be gripped by arc, the first housing 31 and the second housing 32 are additionally provided with six bolts Hole, is bolted to connection between the first housing 31 and the second housing 32.Such benefit is, when needs conversion spacing in the rows, Arc can be replaced by five deciles or the arc of seven deciles, one duckbilled of each self installation and introduce a fine variety dress on each arc Put one modular assembly of composition, and kind of wheel assembly correspondence be replaced by the kind wheel assembly with five or seven pocket grooves, So convenient when changing parts and ressemble.

It addition, as shown in Figure 4, the first housing 31 in the present embodiment is provided with chain replacement operation hole 312, and chain is changed Handle hole 312 is outer is fixed with cover plate (cover plate is the most not shown) by screw.Such benefit is to there is no concern that when assembling Whether the installation direction of duckbilled is installed correctly, owing to the present embodiment have employed two roller brushes 73, even if the installation direction of duckbilled is not Correctly, it is also possible to after unloading lower cover, chain is taken off from the roller brush axle sprocket wheel connected, chain is connected to another roller So that it normally works on brush axle sprocket wheel, it is not necessary to reinstall duckbilled, the technology so installed requires lower, assembling Corrigendum it is easier to during mistake.

As it is shown in figure 1, be fixed with secondary clear brush 9 of planting in the present embodiment on fast pulley 6, secondary clear brush 9 of planting is positioned at kind of a wheel wheel body 51 Lower section, the secondary clear bristle tips planting brush 9 offsets with planting the lateral wall taking turns wheel body 51.If seed is stuck in pocket groove, secondary Seed can be swept in pocket groove by clear brush 9 of planting timely, so for follow-up seeding process, can reduce the general of hole Rate, if because if seed blocks by this pocket groove, follow-up sowing arises that hole always.

As it is shown on figure 3, in the present embodiment, duckbilled 4 includes sharp mouth 41, toe board 42 and the compression bullet that cross section is triangular in shape Spring 43, toe board 42 be hinged on point mouth 41 on, sharp mouth, toe board and the compression spring of duckbilled be configured to prior art, duckbilled Operation principle be such that when the toe board of duckbilled is not in contact with the ground, compression spring withstand toe board makes point mouth sealed by toe board Closing, seed will not drop from duckbilled, and along with the rotation of cylindrical circumferential wall, the duckbilled being positioned at bottom inserts out one on the ground Individual kind of cave, its toe board contacts ground and also compresses compression spring, is opened between toe board and point mouth simultaneously, and seed falls into this kind of cave In, the continuation along with cylindrical circumferential wall afterwards rotates, and toe board disengages with ground, and compression spring makes point mouth by toe again Plate is closed.For easily falling the problem of spring on existing duckbilled in the present embodiment, toe board 42 is provided with projection 421, compression spring One end of 43 is enclosed within projection 421, and the other end of compression spring 43 through arc 331 and is provided with crotch 431 at traversing through end, this Sample will not come off due to crotch 431 and the existence of projection 421, compression spring 43 from duckbilled, adds the reliable operation of duckbilled Property.

In the present embodiment, the material of first housing the 31, second housing 32, arc 331 and fast pulley 6 is ferrum, so makes The weight obtaining the present embodiment is heavier, and intensity is higher, and duckbilled buries deeper, so on mulch film during sowing, owing to duckbilled buries more The hole deeply making mulch film be punctured out by point mouth is the biggest, and after then emerging, seedling is difficult to be blocked by mulch film, is easier to get out mulch film. In the present embodiment, as an adnexa, fast pulley 6 is fixed with kind of case 10, plants case 10 and be provided with out kind of mouth 101, described kind of room The sidewall of 61 is provided with seed inlet 611, and fast pulley 6 is communicated with out the guiding channel 63 of kind of mouth 101 and seed inlet 611, this Sample can supplement seed the most at any time.

Embodiment described above is only to be described the preferred embodiment of the present invention, the not model to the present invention Enclose and be defined, on the premise of designing spirit without departing from the present invention, the those of ordinary skill in the art technical side to the present invention Various deformation that case is made and improvement, all should fall in the protection domain that claims of the present invention determines.
