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

Embodiment Construction

[0023] The seed metering device provided by the present invention will be further described below in conjunction with the accompanying drawings, but the present invention is not limited to the following implementation examples.

[0024] The seed meter provided by the present invention is composed of several kinds of cups 1 and several kinds of cups 2 flexibly connected by connecting ropes 18 to form a cup string, placed on the outer guard rod 4, the inner guard rod 7, the outer guide rail 5, the inner guide rail 6 and the middle guide rail. In the fixed space formed by 9, the outer guard bar 4, the inner guard bar 7, the outer guide rail 5, the inner guide rail 6 and the middle guide rail 9 are affixed to the frame of the planter, and the outer teeth of the rubber belt 10 are affixed to the planter. The groove engagement of the grooved cup hoop 11 of the cup barrel 20 drives the seeding cup string to rotate counterclockwise, so as to achieve the purpose of running the seeding o...

Abstract

The invention discloses a stem-material (section-material) seed sowing device which is equipped with a corresponding planting machine to use. The seed sowing device is characterized in that a plurality of seed cups 1 and a plurality of seed cups 2 are connected by a connecting rope 18 to form a cup string, the cup string is arranged in a fixed space consisting of an outer protective rod 4, an inner protective rod 7, an outer guide rail 5, an inner guide rail 6 and a middle guide rail 9, a bevel gear 19 is driven by a ground wheel to rotate so as to drive the cup string to rotate and to provide operation power for the seed sowing operation; since the positions of notches of the inner guide rail 6, the middle guide rail 9 and the outer guide rail 5 are different, when the cup string rotates in the counterclockwise direction, a circular bottom cover 16 of the seed cup 1 can be automatically opened downwards along a hinge 12 at a seed sowing opening A so as to complete the seed sowing, and a circular bottom cover 15 with a flange of the seed cup 2 can be automatically opened along the hinge 12 at a seed sowing opening B so as to complete the seed sowing. By adopting the seed sowing device, the seed sowing uniformity and per capita operating efficiency of the stem-material (or section-material) planting machine can be improved, and the bud damage rate in the planting process can be reduced.

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...
