Problems solved by technology
[0003] In potato planting agronomy, the whole potato is basically cut into pieces and mixed with suitable medicinal powder or sprayed with bactericidal agents, and then put the potato pieces into the seed box. Unlike the whole potato, the cut potato seeds are oval. The internal fluidity of the seed box is poor, and the potato seeds are easy to stick to each other and stick to the wall of the seed box after being sprinkled with powder or sprayed with chemicals, which leads to the fact that the potato seeds inside the seed box are empty and cannot be quickly Smoothly flow to the bottom of the seed box to fill the potato seeds taken away by the seed cup, and the seed cup can not get the potato seeds and the cup is empty, so the potato miss-seeding occurs, which greatly affects the seeding quality
[0004] In recent years, planter manufacturers have added vibrating structures behind the seed box to make the rear of the seed box vibrate, thereby increasing the fluidity of the potato seeds in the seed box, but the effect of this type of structure to force the potato seeds to fall is very limited. This type of structure is only suitable for the agronomic method of sowing with whole potatoes. When whole potatoes are piled up in the seed box, the vibration can make the oval potato seeds flow inside the seed box, but this structure is not suitable for the agronomic method of sowing in pieces In other words, the effect of vibration is not obvious. After the diced potato seeds are mixed with medicine, the viscosity is very high, and there is a tangent plane, which makes the fluidity of the potato seeds very poor, and this problem cannot be solved by relying on simple vibration. , it is often necessary to sit several workers above the seed box during the sowing process, and force the potato seeds to flow by stirring with a stick, which is time-consuming and laborious, and has a certain degree of danger

The invention relates to a potato seed active conveying device for a potato seeder. The potato seed active conveying device comprises an eccentric driving mechanism and a flow guide plate, and the flow guide plate is arranged in a seed box, is parallel to the rear wall of the seed box, can slide up and down along the rear wall of the seed box, and is provided with a plurality of layers of bent bosses; a flow guide driving shaft is connected with the eccentric driving mechanism and drives the eccentric driving mechanism to work; and the power output end of the eccentric driving mechanism is fixed with the flow guide plate, and the eccentric driving mechanism can drive the flow guide plate to move up and down in the seed box along the rear wall of the seed box. Potato seeds are pushed to a seed taking opening in the bottom of the seed box when the bending bosses move downwards, finally the potato seeds in the seed box flow towards the bottom and fill the potato seeds taken away by a seedcup, the condition that the potato seeds cannot be taken by the seed cup due to the fact that potatoes at the bottom of the seed box are overhead is completely avoided, and the miss-seeding rate is effectively decreased.
