Embodiment Construction
[0024] Such as Figure 1-4 Specific implementations of the air-jet seed clearing combined groove wheel precision seed metering device of the present invention are given. It mainly consists of a seed metering device shell 1, a precision seed metering wheel 2, a leak-proof shaft 10, a leak-proof sleeve 9, a brush 11, an air jet column 5, an air intake column 7, a sowing rate adjustment plate 12, an air pipe 8, and a cleaning Seed groove 14 etc. are formed. The seed metering device shell 1 is assembled by two parts, the left side is provided with the cavity housing, the leak-proof shaft 10, the jet column 5, the air intake column 7, etc., and the right side is provided with the seeding rate adjustment plug-in plate pressure column and There are 4 assembly holes 13 at the upper end of the seed metering device housing 1 for adjusting the inserting slit of the arc seeding rate. The precision seeding wheel 2 is inside the seed metering device housing 1. The inner diameter of the pr...

The invention relates to a precise seed-metering unit with an air injection-seed cleaning combined geneva wheel in the field of agriculture seeding machinery. The precise seed-metering unit is provided with a precise seed-metering wheel which is arranged in a seed-metering unit housing and can rotate, a plurality of rows of small seed-metering holes are formed in one end of the precise seed-metering wheel, seed-metering slots are uniformly distributed in the periphery of the other end of the precise seed-metering wheel, an air injection pillar is arranged at the lower part of the seed-metering unit housing and is internally tangent with the segment of the small seed-metering holes of the precise seed-metering wheel, air vents are formed in the air injection pillar, the end of the air injection pillar is sealed, air injection holes are arranged downwards, and every one row of small seed-metering holes correspond to one air injection hole. Compared with the background art, the precise seed-metering unit has the advantages that seed pushing by a seeding pushing gear is changed to be high-pressure gas seed cleaning, the size and the number of the precise seed-metering holes are not affected by the seed pushing gear, processing can be carried out randomly, and even smaller seeds can be precisely sown.
Description
technical field [0001] The invention belongs to the technical field of agricultural machinery manufacturing, in particular to a seed meter in the accessories of sowing machinery. technical background [0002] There are various types of existing seed metering devices such as grooved wheel type, socket type, pneumatic type, finger clip type, etc., but some functions are single, and the seeding effect on small seeds is poor. Unloading seed metering device", 99202267.3 patent "multi-functional precision seeder metering device" and 200710017665.3 patent "central drive strong push type and half-mouth seeding precision seed metering device" can achieve accurate rowing of small, medium and large seeds However, there are still disadvantages such as complex structure and damaged seed metering device. Contents of the invention [0003] The purpose of the present invention is mainly for the 200710017665.3 patent "central drive forced push type and half-mouth precision seed metering d...
