Abstract

The invention discloses a grain tube automatic opening and closing type sowing machine. The inner sides of bottom ends of every two half cup bodies are connected by using an elastic member; after a sowing tube is inserted into soil, the bottom ends of the two half cup bodies are opened by holding down an operating rod and driving a supporting rod, so that seeds slide into the soil; after the hold-down pressure is released, the two half cup bodies are closed under the action of the elastic member; only the two actions of hold-down and release of the operating rod are only required in one-time operation, thus the sowing machine is easy to operate and the sowing efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of agricultural cultivation, in particular to a seeder with automatic opening and closing of a seed delivery tube. Background technique [0002] A planter is a planting machine that uses crop seeds as the object of sowing. It is used for a certain type or a certain type of crop. It is often named by the name of the crop type, such as grain drill, corn hole sower, cotton seeder, pasture spreader, etc. When the seeder is in operation, the walking wheel drives the seeding wheel to rotate, and the seeds are discharged from the seed cup in the seed box into the seeding pipe according to the required sowing amount, and fall into the opened groove through the opener, and then are covered with soil. The compacting device covers and compacts the seeds. Although a kind of automatic seeder has been developed in the prior art, after the seeding pipe composed of two half-cups is inserted into the soil, the bottom ends o...
