Mechanical auxiliary seed-filling device

Abstract

A mechanical auxiliary seed-filling device is formed by a chain wheel 1, a disc cam 2, a push rod 3, a return spring 4, a connecting rod 5, a linkage push rod 6, a seed-filling poking claw 7, a seed-metering device casing 8 and a seed-metering wheel 9. The chain wheel 1 drives the disc cam 2 to rotate, the disc cam 2 pushes the push rod 3 to perform horizontal reciprocating motion according to a set track under the effect of the return spring 4, the push rod 3 is connected with the linkage push rod 6 penetrating through a seed-filling area through the connecting rod 5, the seed-filling poking claw 7 installed on the linkage push rod in the seed-filling area performs the horizontal reciprocating motion so as to simulate the poking motion of the human hand to disturb seeds, the seeds are filled fully, and seed interruption is avoided. The position of the poking claw in the seed-filling area is adjustable, seed damage is avoided, the chain wheel is driven by a land wheel, the horizontal reciprocating times in unit time is controlled by the seeding speed, the seed-filling effect is guaranteed, and a power source is convenient and reliable. The mechanical auxiliary seed-filling device is suitable for seed-filling requirements of different small-grain crop seeds including foxtail millet, broom corn millet, grass seeds, vegetable seeds and the like.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a mechanical auxiliary seed filling device suitable for mechanized sowing of small grains such as millet, millet and grass seeds. Background technique [0002] Millet, broomcorn, rapeseed and other small-grained grains have not yet matured mechanized fine seeding equipment for a small amount. There are many types of seeding devices such as type seed metering device, pneumatic seed metering device and pneumatic precision seed metering device, but the actual sowing effect can only achieve drill seeding in small grain seeding, and it is very expensive. In order to save seeds when sowing in the field, farmers often adopt "mixing sand" and "mixing grains". Some seed metering devices also need "seed pelleting" treatment, and the external size can be increased before sowing can be carried out. There are also many areas that adopt the original method of "shaking columbine" for sowi...
