Multi-row strip sowing seed flow adjustable sowing assembly

Abstract

The invention discloses a multi-row strip sowing seed flow adjustable sowing assembly, and belongs to agricultural machinery. In the multi-row strip sowing seed flow adjustable sowing assembly, a conical seed distribution body is fixedly installed on the lower part of the inner side of a conical funnel-shaped seed box, a circular inner seat plate is fixedly installed on the bottom end of the conical seed distribution body, an inner gear ring is rotationally installed on the circular inner seat plate, N pin shafts are distributed uniformly on the circular inner seat plate along the circumferential direction, a cylindrical gear sleeves each pin shaft, N racks are installed on the circular inner seat plate, a fan-shaped blade is fixedly installed on each rack, each fan-shaped blade is provided with two or more of seed-leaking through holes with different diameters, a locking disc is fixedly installed on the lower end of the circular inner seat plate, seed-discharging through holes are arranged in the locking disc, an adjusting rod with a positioning buckle is fixedly installed on the inner gear ring, and the positioning buckle is matched with an arc-shaped positioning plate, with positioning clamping mouths, installed on the conical funnel-shaped seed box. The assembly is unique, reasonable and compact in structure, the adjustment operation is simple and easy and convenient, the adjustment efficiency is high, the adjustment accuracy consistency is good, the adaptability is strong, and the use is reliable.

Description

technical field [0001] The invention belongs to agricultural machinery, and mainly relates to a seeding assembly. Background technique [0002] Most of the existing multi-row drill sowing equipment adopts the traditional outer grooved wheel seeding assembly, and the outer grooved wheel seeding assembly is equipped with the number of outer grooved wheel seeding assemblies equal to the number of rows according to the number of rows of the drill operation. According to agronomic requirements, when adjusting the grain flow rate of strip seeding, it is necessary to independently adjust each outer grooved wheel metering device. There are many technical problems such as cumbersome adjustment operations, low efficiency, and difficulty in consistent adjustment accuracy, especially as my country's With the development of intensive agricultural management, large-scale multi-row sowing agricultural machinery has become an inevitable trend, and the above-mentioned problems are more promin...

Problems solved by technology

According to agronomic requirements, when adjusting the grain flow rate of strip seeding, it is necessary to independently adjust each outer grooved wheel metering device. There are many technical problems such as cumbersome adjustment operations, low efficiency, and difficulty in consistent adjustment accuracy, especially as my country's With the development of intensive agricultural management, the large-scale multi-row sowing agricultural machinery has become an inevitable trend. The above-mentioned problems are more prominent. Therefore, it is necessary to develop a new structure of multi-row sowing grain flow adjustable sowing assembly.
