a seed meter

Abstract

The invention discloses a rod material (segment material) seed metering device, which is matched with a corresponding planter. The seed metering device provided by the present invention is characterized in that: several kinds of cups 1 and several kinds of cups 2 form cup strings through connecting ropes 18, and the cup strings are placed on outer guard rods 4, inner guard rods 7, outer guide rails 5, and inner guide rails. 6. In the fixed space formed by the middle guide rail 9, the ground wheel drives the bevel gear 19 to rotate so as to drive the cup string to run to provide working power for the seeding operation; due to the different positions of the gaps of the inner guide rail 6, the middle guide rail 9 and the outer guide rail 5, the cup string When running counterclockwise, the circular bottom cover 16 of the seed cup 1 will automatically open downward around the loose leaf 12 at the seed discharge port A to complete the seed discharge, and the flanged circular bottom cover 15 of the seed cup 2 will automatically open at the seed discharge port B. The loose-leaf 12 is automatically opened to complete the seeding. The seed metering device of the present invention can improve the seed metering uniformity and per capita operating efficiency of the rod material (or segment material) planter, and reduce the rate of bud damage in the planting process.

Description

technical field [0001] The invention relates to a seed metering device, in particular to a seed metering device used in conjunction with a bar material (or section material) planter, and belongs to the technical field of agricultural machinery. Background technique [0002] Rod or segment seed (mainly sugarcane and cassava) planters are special planters. Because the seed material is easily formed in the hopper of the planter, it will seriously affect the uniformity and continuity of the planting process. , The seeding technology of this type of planter is immature. At present, the commonly used mechanical planting method is: the feeder feeds the whole seed stem into the seed cutting port along the length direction, and then cuts the seed segments that meet the requirements by the seed cutting device on the planter, and falls into the seed segment by its own gravity. In the seed ditch opened by the opener, cover soil and suppress it. For example, the more common 2CZX series...

AI Technical Summary

Problems solved by technology

2CZX series sugarcane planters require 3-4 operators for a single row due to the large amount of planting; 2CMS-2 cassava planters need at least one operator in each row. The per capita planting efficiency is low, and the seeds are seriously injured during the feeding and cutting process
