Detailed Description

The utility model is further described with reference to the following figures and embodiments.

Referring to fig. 1-2 in combination, a corn planting structure includes: a housing 1; the rotating shaft 2 is rotatably arranged on the shell 1, and the rotating shaft 2 penetrates through the shell 1; the material distributing gear 3 is fixedly arranged on the rotating shaft 2; the discharging pipe 4 is fixedly installed at the bottom of the shell 1, and the discharging pipe 4 is communicated with the shell 1; the connecting pipe 5 is fixedly arranged at the top of the shell 1, and the connecting pipe 5 is communicated with the shell 1; the connecting shell 6 is fixedly arranged on the connecting pipe 5, and the connecting shell 6 is communicated with the connecting pipe 5; the pipeline 7 is fixedly arranged on the connecting shell 6, and the pipeline 7 is communicated with the connecting shell 6; the piston 8 is installed in the connecting shell 6 in a sliding and sealing mode, and can drop into the distributing gear 3 after distributing corn seeds, so that the distributing gear 3 is prevented from being clamped to influence normal sowing.

Slidable mounting has rack 9 on connecting shell 6, rack 9's one end extend to connecting shell 6 in and with piston 8 fixed connection, the sliding sleeve is equipped with spring 10 on the rack 9, spring 10's both ends respectively with connecting shell 6's inner wall and piston 8 fixed connection, fixed mounting has first belt pulley 12 on the sector gear 11, fixed mounting second belt pulley 13 on the pivot 2, the cover is equipped with same belt 14 on second belt pulley 13 and the first belt pulley 12, can rotate and then drive piston 8 through dividing material gear 3 and move.

And a sector gear 11 is rotatably arranged on the connecting shell 6, and the sector gear 11 is meshed with the rack 9 to enable the piston 8 to reciprocate.

The pipeline 7 is provided with a baffle 15 in a sliding manner, and the baffle 15 is provided with a blanking hole 16 so as to adjust the blanking speed.

The blanking holes 16 are divided into two groups, including a single group and two groups.

The piston 8 is provided with an inclined surface, so that when the corn seeds are accumulated between the pipeline 7 and the connecting shell 6, part of the corn seeds can be pushed into the pipeline 7 again, and the excessive corn seeds entering the connecting pipe 5 are prevented.

The working principle of the corn sowing structure provided by the utility model is as follows:

when the corn planter is used, corn seeds fall into the pipeline 7 through gravity and are accumulated in the pipeline 7, when the planter moves, the rotating shaft 2 rotates, the rotating shaft 2 drives the second belt pulley 13 to rotate, the sector gear 11 rotates under the action of the belt 14 and the first belt pulley 12, and then the rack 9 is driven to move, and when the sector gear 11 rotates to be not meshed with the rack 9, the piston 8 returns under the action of the spring 10, so that the piston 8 can reciprocate in the connecting shell 6;

when the piston 8 moves to the leftmost side, corn seeds cannot fall into the connecting shell 6, when the piston 8 moves to the rightmost side, the corn seeds fall into the connecting shell 6, are pushed into the connecting pipe 5 through the piston 8 and then fall onto the distributing gear 3, and because only a few corn seeds exist in the connecting pipe 5 all the time, the distributing gear 3 cannot be clamped;

when the corn seeds are stacked between the pipeline 7 and the connecting shell 6, the piston 8 slides horizontally, so that the corn seeds are not easy to be clamped relative to the rotation of the distributing gear 3, and the inclined surface is arranged on the piston 8, so that the residual stacked corn seeds can be pushed into the pipeline 7 again;

by pulling the flap 15, the blanking speed of the duct 7 can be adjusted.

1) by arranging the connecting shell 6, the corn seeds can fall into the distributing gear 3 after being distributed, so that the distributing gear 3 is prevented from being clamped;

2) through setting up horizontal motion's piston 8, can pile up the jam in connecting 6 departments of shell by the maize kind, guarantee normal operating, improve seeding efficiency.

Comparative example

As shown in the attached figure 3 of the specification, corn seeds can be stacked at the pipeline and the distributing gear, so that the distributing gear is clamped; and this technical scheme maize kind can pile up in pipeline and connecting shell department, piles up the back under the effect of the promotion of piston 8 and inclined plane, the effectual maize kind motion of promotion.

The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes, which are made by using the contents of the present specification and the accompanying drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
