Corn rotary tillage film mulching precision seeder of planting under film and free putting seedling

Abstract

The invention relates a corn rotary tillage film mulching precision seeder of planting under film and free putting seedling, a film mulching device rack is hinged on the rear of the seeder rack, a film hanging device is hinged with a film mulching device, and a punching device, a film pressing wheel, a second soil coverer and a clean-up scraper are respectively connected with the film mulching device rack; the punching device includes a shaft, a steel tube, nails and a connecting plate which is connected to both sides of the film mulching device rack, wherein the steel tube is fixed on a circumferential surface of the shaft, a rubber layer is arranged on the outer surface of the steel tube, and nail roots are fixed to the steel tube and run through the rubber layer so that nail tips are higher than a surface of the rubber layer; the nail tips of the punching device contact with the film. In the planting method of achieving corn rotary tillage precision planting under film with free putting seedlings, evenly punching is performed on the seedbed area of the film through a punching mechanism, so that the film is permeable to air and water and seeds can achieve their own rupture of the film and emergence with free putting seedling. Planting requirements of film mulching or non-mulching is satisfied, and duplex operation can be carried out in both cultivated land and uncultivated land.

Description

technical field [0001] The invention relates to agricultural machinery and equipment, in particular to a precision seeder for rotary tillage and film-covering of seedling-free corn planting under film. Background technique [0002] Corn is the grain crop with the largest planting area in my country and the grain crop with the highest total output in the world. At present, due to the different frost-free periods, there are mainly two planting methods for corn planting: film-covered planting and non-film-covered planting. The seeders used are also different, and one machine cannot be used for multiple purposes. In addition, the most common use of film-covered seeders is to use a drum-type seeder with a duckbill to sow on the film. The distance between plants also needs to replace the duckbill and the sprocket of the corresponding transmission ratio, which is time-consuming and labor-intensive. Contents of the invention [0003] The invention provides a corn rotary tillage ...
