Abstract

The invention discloses an ejection type seed-metering device and a field operation machine. The ejection type seed-metering device comprises a seed storage box and a seeding device; the bottom of theseed storage box is connected with a downward seed feeding pipe, and a seeding door is arranged at an opening of the seed feeding pipe, the seeding device is arranged on the opposite direction of theseeding door, and the seeding device is used for reciprocating movement to switch the seeding door between opening and closing. The ejection type seed-metering device utilizes a reciprocating seedingdevice to make seeding of the seed-metering device more reliable and at the same time make the position and time of each seeding accurately controlled.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery automation, and more specifically relates to a ejection type seed metering device and a field operation machine. Background technique [0002] The seed meter is a key component of the field sowing equipment. There are various forms of existing seed metering technology, the main types include hole type and pneumatic type. The former has a poor effect on shaped or germinated seeds, while the latter has a complex structure, large volume and high weight, which causes certain difficulties in field operations. [0003] Patent document CN104322182A discloses a seeder, which includes a material storage box and a lower material box located below the material storage box. The bottom of the other side of the lower material box is provided with a discharge pipe, and the seeds slide out from the discharge port. Natural fall. The seeder has a simple structure, thereby reducing the volume of th...
