Small seed potato shifting wheel type seed metering device

Abstract

The invention discloses a small seed potato shifting wheel type seed metering device, and belongs to agricultural machinery; a vertical inner side face and a horizontal upper end face of an L-shaped power driving box assembly are respectively provided with a seed shifting wheel in a rotating manner and a seed filling and supply column in an up and down telescopic moving manner; seed shifting rods are evenly distributed and arranged on the seed shifting wheel; a small seed potato box is arranged on the horizontal upper end face of the L-shaped power driving box assembly, and is located at the outer side part of the seed filling and supply column; the outer part of the upper end of the seed filling and supply column is in a cone shape; a hemispherical pit and a horizontal groove are formed in the upper end face of the seed filling and supply column; a seed metering conveying frame is arranged on the small seed potato box; the hemispherical pit has the diameter of 20 mm. The device has the advantages of novel and reasonable structure, accurate seed metering, low sowing leakage rate, low re-sowing rate, reliable operation and less failure, and meets the requirements of precise sowing.

Description

technical field [0001] The invention belongs to agricultural machinery, and mainly relates to a small potato seed metering device. Background technique [0002] Existing potato seed metering devices mainly contain the following three types: acupuncture type, finger clip type and scoop type. The advantage of the needle-pricked potato seed meter is that it is heavy and has a low rate of missed seeding. Proper selection of the length and configuration of the needles can easily achieve the purpose of piercing only one piece of potato without heavy seeding. The disadvantage is that the needle itself is relatively fragile, easily deformed and damaged, and easily entangled and damaged by weeds, and the work is not durable. Acupuncture is easy to spread potato bad belly and so on. The main sowing part of the finger-clip potato seed meter is the potato clip; its movement direction is perpendicular to the clamping direction, and the clamping process is "grabbing". The opening of the...

Problems solved by technology

However, its structure is more complicated and the price is more expensive, so the cost of sowing for smaller plots is higher

The small seed potato is the original seed potato for planting potatoes, and its diameter is much smaller than that of conventional seed potatoes. Using the above three seed metering potato planting machines to plant small seed potatoes, the phenomenon of seed leakage is serious and the operation quality is poor.
