Problems solved by technology
The mechanical seed metering device has the advantages of simple structure, reliable operation, and low cost. However, the mechanical seed metering device mainly relies on the self-weight of the seeds to fill the hole wheel-shaped holes, which limits the speed at which the seeds fill the hole and affects the rowing of the seed metering device. frequency, which limits the working speed of the seeder

Embodiment Construction
[0011] The invention will be further described below in conjunction with the accompanying drawings and embodiments. A high-speed precision seed metering device, including a housing 4 and a hole wheel 1 configured and installed on the housing 4, a brush wheel 8, a seed protector 9, a seed cleaner 10, a seed sprocket 11, and a brush chain Wheel 12, driving sprocket 13. The hole wheel 1 and the friction disc 2 are coaxially and rotatably installed on the housing 4, and the friction discs 2 are fixed on both axial sides of the hole wheel 1, and the pressure plate 3 is fixed on the housing 4, and the pressure plate 3 Fit between the friction discs 2 with gaps, and fit on the top of the hole wheel 1, the distance between the pressure plate 3 and the hole wheel 1 gradually decreases along the rotation direction of the hole wheel 1, and the pressure plate 3 is made of elastic material .
[0012] The seed guide plate 7 and the seed injection hole 6 are fixed on the upper right side o...

The invention discloses a high-speed precise seed sowing device, belonging to agricultural machinery. A type hole wheel and friction discs are coaxially and rotatably installed on a shell, the friction discs are fixedly arranged at both axial sides of the type hole wheel, pressure plates are fixedly installed on the shell and are installed between the friction discs at intervals and above the type hole wheel, the distance between the pressure plates and the type hole wheel is gradually reduced along the rotation direction of the type hole wheel, and the pressure plates are made of elastic materials; a seed guide plating and a seed inlet are fixedly installed at the right upper side of the shell, the seed guiding plate has an included angle of 30-60 degrees with a plane and is tangent with a bristle wheel, and the seed inlet is contacted with and arranged at the right upper side of the seed guide plate; and an observation plate is fixedly installed at the left upper side of the shell and made of transparent materials. The device has simple structure, enables seeds to be pressed by making use of the friction of the friction discs and the type hole wheel to the seeds, increases the filling force of the seeds and the filling speed and satisfies the requirements of high-speed and precise seed sowing.
Description
Technical field [0001] The invention belongs to agricultural machinery. Background technique [0002] Sowing machinery is one of the most basic production tools in agricultural production, and the seed meter is a key component of sowing machinery. The mechanical seed metering device has the advantages of simple structure, reliable operation, and low cost. However, the mechanical seed metering device mainly relies on the self-weight of the seeds to fill the hole wheel-shaped holes, which limits the speed at which the seeds fill the hole and affects the rowing of the seed metering device. This frequency limits the operating speed of the seeder. Contents of the invention [0003] The purpose of the present invention is to solve the problems existing in the above-mentioned prior art, and provide a high-speed precision seed metering device, relying on the friction force of the friction disc and the hole wheel on the seeds to press the seeds, and increase the hole size of the s...
