Abstract

The invention provides a peanut sowing seed-metering device with adjustable particle size. The peanut sowing seed-metering device comprises an adjusting disc, a discharge plate, elastic baffles and a fixing bolt. The adjusting disc and the discharge plate are fixedly connected through the fixing bolt, so that the friction between seeds in inner cells and a shell of a seed box of the seeder is avoided, the seeds are protected, and the germination rate of the seeds is improved; the elastic baffles are clamped on a circumferential outer wall of the adjusting disc through elastic force, and are opposite to the positions of feed preparation holes one by one; two groups of positioning holes are formed in the adjusting disc, and are matched with positioning holes in the discharge plate respectively; and the device is suitable for seeding large peanuts when the elastic baffles are positioned at the feed preparation holes, and is suitable for seeding small peanuts when the elastic baffles are positioned at the inner cells, so that the classified seeding for seeds with different particle sizes is realized, the double grain rate and accuracy of the seeding are improved, the seeds of peanuts are effectively saved, and the workload of the thinning of laborers is reduced.

Description

The peanut seeding seeding unit of scalable granule size

Technical field

The present invention design relates to the peanut seeding machine technology, is a kind ofly to regulate peanut seeding seeding unit inner hole size through different station, realizes improving Peanut seeding appts. seeding precision, reduces the device of seed consumption and protection seed.

Background technology

Since China's entry into the World Trade Organization, the outlet of Shandong Province's peanut increases considerably, and has accounted for more than 80% of national peanut outlet, and peanut planter also along with rolling up, has significance to improving peanut yield and quality.

Present already present peanut planter model is more, but used seeder can only be sowed the seed of certain particle size, and is inhomogeneous for the planting seed grain number that granule size is uneven, also wastes seed.We have designed a kind of peanut seeding seeding unit that can regulate granule size, can realize the adjusting of internal nest hole size, thereby have solved the accurate sowing problem of seed grain number, have reduced the planting seed consumption, have improved seed germination rate.

Summary of the invention

The purpose of this invention is to provide a kind of peanut seeding seeding unit, realize purpose, reach the requirement that accurately to sow the different grain size seed, reduce the planting seed consumption, improve seed germination rate inner hole size adjustment on the seed plate.

The present invention is achieved through taking following technical scheme: through an adjustment dish is installed on seeding unit; Different stations is equipped with elastic baffle between adjustment dish and the seed plate; Scalable peanut seeding seeding unit inner hole size realizes the different grain size seeds in size is realized seeding.

Implementation procedure is: when sowing is than the coarsegrain seed; Elastic baffle on the adjustment dish is in the place, hole that gets the raw materials ready in compound type hole on the seed plate; When will sow than the small grain size seed; Elastic baffle is adjusted to the inner hole place in compound type hole, makes the size decreases of inner hole, thereby can realize the seeding than the small grain size seed.

The invention has the beneficial effects as follows: because the existence of adjustment dish; And match with inner hole seed plate through on the adjustment dish; Pass through different station; Solved because of the different problems that can not accurately sow of peanut seed granularity, made the seeding property of sower seed wheel improve more than 30%, improved operating efficiency greatly.Simultaneously, reduced the frictionally damage of seed, improved seed germination rate because seed and the friction of seeding unit shell in the compound type hole avoided in the existence of adjustment dish.

Apparatus of the present invention respective outer side edges is ingenious, and is easy to adjust, a tractor serves several purposes, but the seeding effect is clearly better.

Embodiment

In the embodiment shown in Fig. 1 ~ 3: adjustment dish (1) and seed plate (2) are fixed together through set bolt (4), have avoided seed and the friction of sower seed-box shell in the inner hole, have reduced the friction of seed, have improved emergence rate.

Seed plate (2) is provided with a plurality of holes of getting the raw materials ready (5) and inner hole (6); Adjustment dish (1) is provided with centre bore (7) and three locating holes (8); Elastic baffle (3) is stuck on the outer circumferential walls of adjustment dish (1) through elastic force, and corresponding one by one with the position of the hole of getting the raw materials ready (5); Two groups of locating holes (8) are arranged on the adjustment dish (1), the two groups of locating holes (8) on the adjustment dish respectively with seed plate (2) on locating hole match, when elastic baffle (3) is in position, the hole of getting the raw materials ready (5); Be fit to the big grain of sowing peanut; When elastic baffle (3) is in inner hole (6) position, the width of inner hole (6) is diminished, be fit to sowing granule peanut; Thereby realize to different grain size seeds in size classification sowing; Change the drawback that occurs multicast kind grain when old seeder is sowed the granule peanut easily, effectively practiced thrift peanut seed, reduced the workload of labourer's thinning.
