Abstract
The utility model relates to a rice direct-sowing seed metering device, belonging to agricultural machinery. A shell is fixed on a rotating shaft, and the rotating shaft is movably sleeved with a seed metering amount adjustment cam; a seed metering amount adjustment bolt connects the seed metering amount adjustment cam with the shell into a whole; shared holes for replenishing and metering seeds are uniformly arranged on the circumferential sidewall of the shell; a seed metering rocker bar is hinged inside a shell cavity through an axis pin; a seed metering boss is arranged on the inner side of the seed metering rocker bar; the seed metering boss is in contact or separate fit with a seed metering push roller which is arranged on a machine frame and positioned inside the shell cavity; and a pressure spring is arranged between the shell and the seed metering rocker bar and is in compressing contact fit with the shell and the seed metering rocker bar. The seed metering device is novel in design, simple in structure, good in direct sowing operation quality, high in efficiency and few in faults, can be arranged on various rice direct sowing machines for use, has a wide adaptive range, and can realize the adjustment of rice direct sowing amount.
Description
Technical field
The utility model belongs to agricultural machinery, relates generally to the seeding-apparatus assembly that the rice direct-seeding operation is used.
Background technology
Rice direct-seeding promptly is that rice paddy seed is directly broadcast a kind of agronomy planting patterns of executing on the soil, field, is different agricultural methods with raising rice seedlings, planting.For many years, the rice direct-seeding mode is partly still being used in paddy rice plantation area in China, and obtains agriculture preferably harvest.Traditional rice direct-seeding is by manpower is manual rice paddy seed directly to be shed at rice field, and uneven sowing is even, of poor quality, seed waste loss is big, the production cost height is its significant technical bug.In recent years, a kind of rice direct-seeding assembly of rotary screen structure research and development are come out, but since problems such as operating efficiency is low, sowing uniformity difference in production practices, do not applied.
Summary of the invention
The purpose of this utility model is exactly the problem that exists at above-mentioned prior art, and design provides a kind of rice direct-seeding seeding unit of new structure, reaches the purpose that improves operation quality and operating efficiency, saving seed, reduces production costs.
Basic design of the present utility model is, installs housing, movable set amount of seed metering adjustment cam on turning cylinder, and the amount of seed metering adjustment cam is positioned at the housing chamber, and amount of seed metering is regulated bolt amount of seed metering adjustment cam and housing are linked into an integrated entity; Uniform setting is filled and is planted and the seeding common hole on the housing circumferential side wall, bearing pin is hinged the seeding rocking bar and is installed in the housing chamber, the seeding rocking bar is positioned at amount of seed metering adjustment cam periphery, seeding rocking bar one termination is positioned to fill plants and seeding common hole inside, on seeding rocking bar medial surface, be provided with the seeding boss, this seeding boss be fitted in frame on, be positioned at the contact of the endoceliac seeding push roller of shell or separate cooperation; Compression spring is fitted in to compress between housing and the seeding rocking bar and contacts cooperation, so far constitutes the rice direct-seeding seeding unit.
The utility model modern design, simple in structure, the direct seading rice operation quality is good, efficient is high, fault is few, applied widely, and can realize the seeding quantity adjusting, can be fitted on the various rice growing facility and use.
