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 an ejection type seed metering device and a field operation machine. Background technique [0002] The seed metering device is a key component of farmland planting equipment. The existing seed metering technology has various forms, the main types include hole type and pneumatic type. The former has a poor effect on abnormal 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 storage box and an unloading box located below the storage box. The bottom of the other side of the unloading box is provided with a discharge tube, and the seeds slide out from the discharge port. Natural fall. The seeder has a simple structure, thereby reducing the size of the seeder. [0004] However,...
