Circular groove tapered invaginated spoon type seed arrangement device partition plate

Abstract

The invention relates to a circular groove tapered invaginated spoon type seed arrangement device partition plate and belongs to agricultural machinery. An adjusting hole, a wide shallow groove seed filling section, a wide deep groove fine seed transition section, a narrow deep seed carrying section and a seed falling groove are formed in the outer surface of the partition plate circumferentiallyanticlockwise and sequentially; the circumferential included angles of the wide shallow groove seed filling section, the wide deep groove fine seed transition section and the narrow deep seed carryingsection are 145 degrees, 15 degrees and 65 degrees correspondingly; the thickness, the groove top width and the groove bottom width of the wide shallow groove seed filling section, the wide deep groove fine seed transition section and the narrow deep seed carrying section are h1, h2 and h3, Q1, Q2 and Q3 as well as P1, P2 and P3 correspondingly; h1 is less than h2 and h2 is equal to h3, Q1 is equal to Q2 and Q2 is more than Q3, and P1 is more than P2 and P2 is more than P3. Through the special design structure of the partition plate, the seed filling property of a seed accommodating space formed by a spoon and the partition plate, the single fine seed rate of the wide deep groove fine seed transition section and the stable seed carrying property of the narrow deep groove seed carrying section are improved separately, the problem of high leakage sowing rate of the partition plate under slope and vibration conditions is solved and the high-speed working performance of the partition plate is improved. Moreover, the partition plate is novel in design, simple in structure and reliable in quality.

Description

technical field [0001] The invention belongs to agricultural machinery, and mainly relates to a ring-groove tapered indented scoop-type seed-metering device clapboard fitted with a spoon-type precision seed-metering device. Background technique [0002] At present, the spoon-type seed metering device is widely used as a mechanical precision seed metering device. It has the advantages of no seed damage during operation, no seed clearing device, reliable seed metering performance, and high precision sowing rate. The seed holding space is mainly formed by the spoon of the spoon wheel and the partition. Since the size of the seed holding space remains unchanged during the operation of the seed metering device, and the seed holding space adopts a hemispherical lifting method for seeds instead of a finger clip The clamping and carrying of seeds adopted by the type seed metering device, therefore, its operating speed can only reach 8 kilometers per hour, and at this time, it has a...

AI Technical Summary

Problems solved by technology

The seed holding space is mainly formed by the spoon of the spoon wheel and the partition. Since the size of the seed holding space remains unchanged during the operation of the seed metering device, and the seed holding space adopts a hemispherical lifting method for seeds instead of a finger clip The seed metering device adopts the clamping and carrying of seeds, so its operating speed can only reach 8 kilometers per hour. At this time, it has a high rate of missed seeding

In addition, the spoon-type seed meter will have problems such as multiple uphills, downhill, and few seeds lost on slopes, and when the machine vibrates, it may also cause missed seeding, and the seed loss will be more serious.
