Handheld single and double grain crop experiment sowing machine

Abstract

The invention relates to a handheld single and double grain crop experiment sowing machine and belongs to the field of agricultural machines. The machine comprises a machine frame provided with a sowing device and a sowing leg, and a control mechanism, wherein the control mechanism comprises a handle and a linkage rod hinged to the handle, the sowing leg is a round tube provided with a wedge angle, a baffle is arranged in the round tube, and sowing of the sowing device and opening and closing of the baffle in the sowing leg are achieved through lifting of the handle by means of the linkage rod; the sowing device comprises a seed storage bin and a seed falling bin separated through a partition board, the bottom output end of the seed falling bin is fixedly connected with a sowing tube, the seed storage bin is provided with a lifting mechanism and comprises two seed extraction ejector rods attached to the partition board and a lifting level on the lower portion, a through hole corresponding to the seed extraction ejector rod is formed in the end face of the partition board, a shifting piece capable of blocking the through hole is hinged to the end face of the partition board, and the lifting lever pushes the seed extraction ejector rod to eject seeds so as to enable the seeds to fall into the seed falling bin through the through hole, so that the number of seeds in each hole is accurate. By the adoption of the sowing machine, labor intensity is relieved, and working efficiency is improved greatly; due to the simple structure, manufacturing cost is low.

Description

technical field [0001] The invention belongs to the field of agricultural machinery, and in particular relates to a hand-held single- and double-grain crop test seed planter. Background technique [0002] As the main food crop in our country, corn occupies a very important position in agricultural production. In order to increase the yield of corn, the breeding of corn seeds is an extremely important aspect. [0003] To cultivate high-quality corn seeds in the corn seed experiment field, first of all, it is necessary to screen the crop seeds and select seeds with good genetic traits for sowing experiments. These seeds used for experiments are often in small quantities, and then these seeds are sown. During the sowing process, it is necessary to accurately sow according to the experimental plan, so as to avoid non-unique variables and cause the experimental results to have no reference significance. The existing hand-held seeders used in the test field cannot guarantee accur...
