Abstract
The invention discloses a multi-line integrated blowing-type metering device, and belongs to the technical field of agricultural machinery. The multi-line integrated blowing-type metering device comprises a seeding frame weld, a seed feeding adjustment plate, a seed-clearing device, a metering roller component, a rubber flap, a rubber plate, a lower clamp ring plate, an upper clamp ring, a discharging plate, a bearing block component, a first elastic cylindrical pin, a metering device outer cover weld, a seed dropping opening wind shield, a seed guide tube and a metering device cover plug, wherein the bearing block component is connected with the metering roller component through the first elastic cylindrical pin, and the seed feeding adjustment plate, the seed-clearing device, the rubberflap, the rubber plate, the lower clamp ring plate, the upper clamp ring, the discharging plate, the bearing block component, the metering device outer cover weld, the seed dropping opening wind shield and the seed guide tube are fixed onto the seeding frame weld through bolts. The metering mode of the metering device adopts a multi-line integrated blowing-type centralized metering principle, themetering device is simpler in structure and higher in integration degree, seeds can be loose before seed filling by the aid of blowing-type metering, seed filling effects are improved, and high-speedoperation is facilitated.
Description
technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a multi-row integrated air-blowing seed metering device. Background technique [0002] At present, the commonly used seed metering devices in my country can be divided into two categories: drill sowing and hole sowing according to the sowing method. Drill seed metering devices include outer groove wheel type, spoon type, grinding disc type, centrifugal type and so on. The seed metering devices for hole sowing include hole plate type, hole wheel type, finger clip type and pneumatic type. According to whether the seed meter can form uniform seed flow at equal intervals and accurately control the amount of seed, it can be divided into precision seed meter and non-precision seed meter. There are mainly two types of precision seed meters: mechanical and pneumatic. Among them, the pneumatic seed metering device includes three types: air suction type, air b...
