Problems solved by technology

The traditional hole-sowing seed meter for peanuts mainly uses double-grain hole-sowing, the sowing accuracy is 2 grains / hole, and there are problems such as high breakage rate (thin skin is easy to fall off), low survival rate, etc., especially for single-grain precision sowing (1 grain / hole), it is more important to reduce the broken rate

Embodiment Construction

[0029] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0030] like figure 1 As shown, a precision metering device for peanuts includes a drive wheel 1, a seed feeding port 5, and a seed outlet 8. The peanut precision metering device also includes a seed side plate 2, a drive gear 3, and a Plate 4, active tongue seeding mechanism 6, gear drive disc 7.

[0031] like image 3 As shown, the active tongue seeding mechanism 6 is a key component of seeding, including a hole 10, a movable tongue installation shaft hole 11, and a forced seeding projection 12, wherein the hole 10 is a profiling groove designed according to the shape of the seed. Active tongue seeding mechanism 6 is movably connected with pin shaft and gear driving plate 7 through the installation hole on the gear drive plate, and torsion spring is installed on the pin shaft, controls the reset after active tongue planting mechanism 6 throw...

Abstract

The invention relates to a peanut single-grain precise seed-metering device, especially a single-grain precise seed-metering device aiming at agricultural machinery, and belongs to the technical field of agricultural machinery. The peanut single-grain precise seed-metering device is characterized in that a movable lug seed charge mechanism (6) is movably connected with a gear drive plate (7) through a pin shaft with a torsional spring; the gear drive plates (7) are movably arranged on respective circle center locating bump outer rings of a seed discharge side plate (2) and a seed feeding side plate (4) in a sleeved mode; the seed discharge side plate (2) and the seed feeding side plate (4) are axially located by bolts; a transmission wheel (1) and the drive gear (3) are coaxially installed; power is transferred by the transmission wheel (1) through gears at two ends of the drive gear (3) and gears at two ends of the gear drive plate (7); and a smooth curve surface of the drive gear (3) is tangent with the smooth curve surface of the gear drive plate (7). Thus, the movable lug seed charge mechanism (6) forcibly charges seeds, and the seeds are filled from a seed adding opening (5) and discharged from a seed discharge hole (8) in a single grain form.

Description

technical field [0001] The invention relates to a precision seed metering device for peanuts, in particular to a precision sowing device for single-seed peanuts of agricultural machinery, and belongs to the technical field of agricultural machinery. Background technique [0002] Peanut is one of the important economic crops in my country, with a planting area of ​​about 5 million hectares and a total output of about 14 million tons, accounting for more than 40% of the world's total peanut output, ranking first in the world. At the same time, my country is also the largest peanut producer. consuming and exporting countries. In recent years, due to the adjustment of the planting structure and the promotion of new technologies, the area of ​​peanut planting in my country has continued to expand, and the output has increased year by year. It is necessary to vigorously improve the mechanization of peanut planting. [0003] For a long time, peanuts have been sown with two seeds pe...
