Embodiment Construction

[0068] The present invention is further described below in conjunction with embodiment.

[0069] Such as Figure 1 ~ Figure 3 As shown, the synchronous low-pressure circumferential air suction precision seed metering device of the present invention includes a rear housing 1, a rear air chamber disc 2, a sprocket 3, a bearing 4, an air intake pipe 5, a seeding disc 6, and a front air chamber disc 7 , front housing 8, clearing knife 9, kind box 10, storage box 11, unloading kind knife pressing piece 12 and unloading kind knife 13.

[0070] Such as image 3 As shown, the front housing 8 is in the shape of a disc, and hinged ears 801 and fixed ears 802 are arranged symmetrically on its outer edge.

[0071] Such as Figure 4 ~ Figure 6 As shown, the cross section of the rear housing 1 is in an inverted "convex" shape, with a first chamber and a second chamber; the upper and lower parts of the side wall 103 of the first chamber are respectively provided with a seed inlet 105, a s...

Abstract

The invention belongs to the technical field of agricultural machinery, and in particular relates to a synchronous low-pressure peripheral air-aspiration type precise seeding device which comprises a rear casing (1), a rear air chamber disc (2), a chain wheel (3), a bearing (4), an air inlet tube (5), a seeding disc (6), a front air chamber disc (7), a front casing (8), a seed cleaning cutter (9), a seed box (10), a seed storage box (11), a seed discharge pressing plate (12) and a seed discharge cutter (13). As the seeding disc of the synchronous low-pressure peripheral air-aspiration type precise seeding device is fixedly connected with an air chamber, pressure loss and member abrasion caused by relative rotation can be reduced; the seeding device is used for feeding seeds by virtue of seed gravities and air pressure, the seed feeding property can be improved, and the air pressure requirements can be met; as the air inlet tube is of integral design, air can be directly fed into the air chamber, and air flow loss caused by connection can be avoided to the maximum extent.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a synchronous low-pressure circumferential air-suction precision seed metering device. Background technique [0002] The seeder is an important agricultural equipment that has a significant impact on agricultural production. As the core working part of the planter, the seed meter directly affects the effect of the sowing operation. At present, most of the seed metering devices used in the world are pneumatic seed metering devices. This type of seed metering device has the advantages of high operating precision, fast sowing speed, low requirements on the shape and size of seeds, and little influence of mechanical vibration on seed metering. [0003] At present, the domestic air-suction seed metering device is in its infancy. The structure mostly adopts the relative rotation of the seeding disc and the chamber. The air-suction seed metering device of Ch...
