Under-film seedling-placement-free planting type rotary tillage film-mulching precision planter for corn

Abstract

The invention relates to an under-film seedling-placement-free planting type rotary tillage film-mulching precision planter for corn. The rotary tillage film-mulching precision planter is characterized in that a film-mulching device frame is hinged to the rear of a frame, a film hanging device is hinged to the film-mulching device frame, a perforating device, film pressing wheels, a second covering device and a scraper bar are connected with the film-mulching device frame, the perforating device comprises a shaft, steel pipes, nails and connecting plates, the connecting plates are connected with two sides of the film-mulching device frame, the steel pipes are fixed on the circumferential surface of the shaft, a rubber layer is arranged on the outer surface of each steel pipe, the roots of the nails are fixed on the steel pipes and penetrate through the rubber layers to enable the nail points to be higher than the surfaces of the rubber layers, and the nail points of the perforating device contact with a mulching film. The under-film seedling-placement-free planting type rotary tillage film-mulching precision planter for the corn has the advantages that an under-film seedling-placement-free type rotary tillage precision planting method for the corn can be achieved; the perforating device is used for uniformly perforating a seedbed area on the film to achieve water permeability and air permeability, and seedlings growing from seeds can emerge by breaking the film without manual placement; the rotary tillage film-mulching precision planter can meet the planting requirements of film mulching or no film mulching and can be used for multiple operation in tilled fields or untilled fields.

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 ...
