The charge seed side edge of mouth is provided with hinge, hinge is provided with depression bar and valve mouth, stage clip is provided with between depression bar and seed wheel housing, the charge seed opposite side edge of mouth is provided with baffle plate, depression bar is subject to the pressure cut out cock door of stage clip under field conditions (factors), valve mouth is closed mutually with baffle plate, closes mouth of charging seed, now form a shifting cavity between valve mouth and baffle plate; Cavitation shovel housing on be provided with cavitation shovel, cavitation shovel rear portion cavitation shovel housing on be provided with out kind of a mouth, go out kind of metastomium cavitation shovel housing inwall on there is the briquetting can stirring depression bar.

Conveniently control to enter the grain weight containing kind of case, described seed input pipe top is provided with drawing and pulling type valve.

Conveniently realize the adjustment of program request spacing in the rows, described main shaft is provided with cone pulley.

In order to prevent seeds all when rotated from all dropping containing in kind of case, described socket bore be L-type, and the cavity ratio of close seed wheel outer wall is long near the cavity length of seed wheel inwall, and the part had more is contrary with the direction that main shaft rotates.

Structure of the present invention is simple, reliable operation, can realize the program request to not having through the corn seed selected easily, and spacing in the rows is adjustable simultaneously, meets the requirement of maize dibbling.

Embodiment

Below in conjunction with the drawings and specific embodiments, the present invention will be further described.

As shown in Figure 1 to Figure 3, a kind of maize dibbling device, comprise kind of case 1, seed input pipe 3, end cap 4, containing kind of case 12, main shaft 16, seed wheel 17, a seeds protecting plate 6, go out kind of mouth 22, valve mouth 8, cavitation shovel 9, composition such as cavitation shovel housing 10, seed wheel housing 18 etc., wherein, main shaft 16 is connected with seed wheel 17 by key 15.

As shown in Figure 1 and Figure 2, seed wheel 17 outer setting has cavitation to shovel housing 10, and seed wheel housing 18 is close to seed wheel outer wall, and seeds protecting plate 6 is close to seed wheel inwall;

As shown in Figure 1, main shaft 16 is connected with end cap 4 by bearing 5; Described end cap and seed wheel 17 inwall cavity volume form containing kind of a case 12; Seed wheel housing 18 and seeds protecting plate 6 are all arranged on end cap 4 inwall.

As shown in Figure 2, seed wheel 17 inwall is evenly provided with socket bore 23;

As shown in Figure 2, seed wheel housing 18 bottom has mouth 7 of charging seed, and a mouthful edge of charging seed is provided with hinge 21, depression bar 24, valve mouth 8 and stage clip 20 etc.;

As shown in Figure 2, cavitation shovel housing 10 evenly has out kind of mouth 22, goes out kind of a mouth sidepiece and is provided with cavitation shovel 9; Cavitation shovels inner walls, goes out near kind of mouth to be provided with briquetting 19.

As shown in Figure 1, plant case 1 and be arranged on end cap 4 outside, be connected with end cap through seed input pipe 3; Kind lower box part, seed input pipe top are provided with drawing and pulling type valve 2.

As shown in Figure 1, main shaft 16 is provided with cone pulley 13, to realize the adjustment of program request spacing in the rows.

During work, outside power source drives cone pulley 13 to be rotated counterclockwise.Under the active force of cone pulley, main shaft 16 drives seed wheel 17 and cavitation shovel housing 10 to rotate.

Figure 2 shows that starting point, seed wheel 17 is rotated counterclockwise, and after socket bore lays out from seeds protecting plate, several the seeds containing kind of case fall into socket bore automatically; When seed wheel rotates 150 ° to 180 °, seed unnecessary in socket bore falls back containing kind of a case under gravity from socket bore; Seed wheel continues rotation 30 °, and socket bore enters seeds protecting plate, under seeds protecting plate protection, when the seed wheel mouth of charging seed rotated to socket bore and seed wheel housing intersects, seed in socket bore falls into the shifting cavity of valve mouth and baffle plate composition through mouth of charging seed, and meanwhile, cavitation shovel starts to dig cave; Seed wheel is rotated further, and when the briquetting 19 jack-up depression bar 24 of projection, cavitation has shoveled and dug cave, meanwhile, under the effect of briquetting, opens shifting cavity, and seed is fallen into cavitation from shifting cavity and shoveled through going out kind of mouth the hole dug.
