Seeding device and seeding pipe

Abstract

The invention discloses a seeding device and a seeding pipe. The seeding device comprises a rack and a seeding assembly, wherein the seeding assembly is fixedly connected to the rack; the seeding assembly comprises a seeding tank, a connecting pipe and the seeding pipe; the seeding tank is fixed to the top of the rack; the seeding pipe is connected to the bottom of the seeding tank through the connecting pipe. The seeding pipe comprises a first pipe section, a second pipe section and a seeding box with an opening facing the rear side of the seeding direction. The first pipe section is connected to the bottom of the seeding assembly; the top of the second pipe section is fixedly communicated with the bottom of the first pipe section; the bottom of the second pipe section is inclined towardsthe rear side of the seeding direction, and the bottom of the second pipe section is communicated with the seeding box. The two side walls of the seeding box are straight, and the distance between the two side walls is equal to the diameter of the second pipe section. The seeding pipe is contaminated by less soil and fewer weeds, and the seeding pipe is convenient to clean.

Description

technical field [0001] The invention relates to the field of sowing technology of a sowing device, in particular to a sowing device and a sowing pipe. Background technique [0002] The sowing device is mainly composed of three modules: rotary tillage, fertilization and sowing. Under the pull of the traction machinery, the automatic sowing of crops is realized, which saves labor and has high sowing efficiency. [0003] The end of the sowing pipe of the existing sowing device is bent toward the front end of the sowing direction, and the front side of the sowing pipe end is equipped with a soil-removing cone, which is used to turn the soil again after the rotary tiller has plowed the soil to ensure that the soil is loose And can carry out seeding, but after existing rotary tiller plows the soil, soil laxity just can reach the requirement of sowing fully, and because the end of existing sowing pipe bends toward the front end of sowing direction, cause soil-digging cone , A larg...
