Low-position belt clamp type seed-metering device suitable for multi-seed hole collection and precision seeding

Abstract

The invention discloses a low-position belt clamp type seed-metering device suitable for multi-seed hole collection and precision seeding. The low-position belt clamp type seed-metering device comprises a seed-metering mechanism, a seed throwing mechanism and a power mechanism, the seed metering mechanism comprises a front shell, a rear shell, a seed metering disc, a seed supporting table, a seed protecting plate and a seed unloading plate; the seed feeding mechanism comprises a seed feeding shell and a seed feeding belt; the upper part of the seed throwing shell is communicated with the seed discharging opening, the seed throwing belt comprises two clamping and conveying belts which act synchronously, the two clamping and conveying belts are provided with an upper driving wheel and a lower driven wheel which correspond to each other, the inner ends of the two upper driving wheels are in transmission connection through a synchronous gear, and the power mechanism comprises a seed throwing wheel, a seed metering wheel and a power wheel; the power wheel is in transmission connection with one end of the seeding rotating shaft through a chain; the seed feeding rotating shaft is sleeved with a seed feeding wheel, the seed metering rotating shaft is sleeved at the other end of the seed metering wheel, and the seed feeding wheel is in transmission connection with the seed metering wheel through a chain; according to the seed feeding device, seeds are fed in the mode that the synchronous belt clamps the seeds, the conditions of bounce, collision and the like of the seeds in the seed feeding process are avoided, and accurate seed feeding is achieved.

Description

technical field [0001] The invention belongs to the technical field of seed metering devices, and in particular relates to a low-position belt-clamp type seed metering device suitable for multi-grain seed collection and precision sowing. Background technique [0002] With the expansion of the planting area of ​​peanut, corn and bean crops year by year, mechanized precision sowing of crops is particularly important in order to increase production and save costs. Seed meter is the core component of precision seeding, its working performance directly affects the quality of seeding. The existing socket type seed metering device has a low number of single seeding, uneven seed spacing after seeding, scattered seeds, poor hole collection performance, and slow seeding speed, which cannot meet the requirements of high-speed precision seeding. [0003] At the same time, the existing seed guide device is a tube structure, and the seeds will collide with the seed guide tube and the see...
