Small full-automatic sowing machine

Abstract

The invention discloses a small full-automatic sowing machine which comprises a frame. Front walking wheels and rear walking wheels are arranged at the lower end of the frame. An opener is arranged at the position, located in front of the front walking wheels, of the frame. A supporting frame, a sowing pipe and a soil covering device are sequentially arranged between the front walking wheels and the rear walking wheels from front to back. A fertilizer box, a power device and a seed box are sequentially arranged at the upper end of the frame from front to back. An eccentric rotating plate is arranged on the power device. A first connecting rod is movably arranged on the eccentric rotating plate. A second connecting rod is connected to the other end of the first connecting rod. The middle of the second connecting rod is hinged to the supporting frame. The other end of the second connecting rod is fixedly provided with a drilling head. One end of the sowing pipe is connected to the bottom face of the seed box. An operation room is arranged at the position, located at the front end of the fertilizer box, of the frame. By means of the sowing machine, sowing efficiency is improved, and labor is reduced.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a small fully automatic seeder. Background technique [0002] At present, the sowing of crops has been widely carried out by machinery. Some mountainous farmlands cannot be operated due to the large-scale ditching planter. Most farmers still use manual sowing. Before sowing, they first ditch, and then manually put the seeds into the opened ditch accurately. Then cover the soil and compact it; farmers in a small number of areas use small seeders capable of ditching and sowing for sowing. Although the ditching and sowing of this kind of seeder are done by machinery, the effect of ditching is not good, and the follow-up Fertilization, levelling, and soil compaction are all done manually, and the labor intensity of farmers is still high, and the work efficiency is low. Contents of the invention [0003] The object of the present invention is to provide a kind of sma...
