Description

A seed metering device with adjustable seed spoon

technical field

The utility model belongs to the technical field of agricultural machinery, and mainly relates to an adjustable precision seed metering device, which can be used for sowing various crops such as cotton, corn, peanuts, soybeans and vegetables.

Background technique

According to the principle of seed metering machine, precision seeder can be divided into two types: mechanical type and pneumatic type. Among them, the mechanical type realizes the sowing operation of different crops such as corn, peanuts, cotton, vegetables, beans, and sugar beets by replacing the scoop wheel of different types of seed metering devices. The vertical spoon wheel seed meter is a mechanical precision seed meter with a vertical spoon wheel. It is composed of a seed metering spoon wheel with a spoon, a seed guide wheel, a partition, a seed metering shaft, a seed metering device housing, a seed metering device cover and other parts. Generally, 18 spoon handles of the spoon wheel are evenly arranged in the circumferential direction, and the spoon handles of each seed spoon are all inclined 15° to 35° to the same side to ensure the correct posture of "scooping" the seeds. The part of the spoon wheel that "scoops" seeds is called a spoon, and its shape is round, oval, olive, etc. with different diameters. Its volume and seed size determine the number of seeds in each spoon, which can realize single-grain on-demand , multi-seeding and drilling. This kind of seed metering device does not damage the seeds during operation, has no seed cleaning device, and has reliable seed metering performance, which is very popular among farmers. At present, when this kind of metering device changes the distance between plants or the number of grains per rice, it is all realized by adjusting the transmission ratio. Sometimes the plant spacing of different crops is very different. Even for the same crop, the plant spacing requirements are different in different regions. Simply adjusting the transmission ratio cannot meet the plant spacing requirements. According to the requirements of the farmers, the agricultural machinery manufacturer artificially cuts the spoons of the one-piece casting 18-handle spoon wheel, leaving one spoon for every other spoon, and becomes 9 spoons for work, or cuts two spoons for every other spoon , each fracture is very irregular, which wastes materials and costs, and affects the structural strength of the original scoop wheel, and even affects the seeding performance.
