Device for spirally collecting mulching films in seedling stage of tobacco and operation method

Abstract

The invention discloses a device for spirally collecting mulching films in the seedling stage of tobacco and an operation method. The device for spirally collecting the mulching films is additionally installed on a machine frame of a film uncovering machine through a fixing frame. When the film uncovering machine is in work, the film uncovering machine walks forward and drives a plough share in the device for spirally collecting the mulching films to plough mulching films stacked among ridges and a part of mulching films embedded in soil up and transport the mulching films to an auger delivery feed hole on the rear portion, and under action of a forward-direction screw blade and a reverse-direction screw blade on a spiral shaft, the mulching films are transported to the position of a film downloading hole and collected through a collection box. The device has the following advantages that the structure is simple, the design is ingenious, moreover, the device is not easy to twine, film downloading is simple, film uncovering can be continuously conducted, the efficiency is high, the film uncovering rate is high, at the same time, the recycling problem of a part of the mulching films embedded in the soil in furrows is solved, and the film uncovering rate of the film uncovering machine is improved.

Description

technical field [0001] The invention relates to a tobacco seedling-stage mulching film spiral wrapping device and an operation method, and belongs to the technical field of film-removing machine transformation. Background technique [0002] At present, the tobacco mulching planting technology is a practical technology widely used in my country to increase agricultural production and income. This technology has many advantages such as water saving and drought resistance, temperature increase and moisture conservation, weed control, cost saving and efficiency increase. However, if the plastic film is not recovered in time at the seedling stage, the plastic film will prevent the external precipitation from entering the ridge body, and it will easily cause serious waterlogging in the soil when it encounters continuous rainfall, which will deteriorate the soil permeability, hinder the evaporation of water, and affect the growth of the plant. Therefore, the recovery of plastic fi...

Problems solved by technology

The small tobacco seedling mulch recycling machine invented by Lu Zhaoqin of Shandong Agricultural University and others (patent application number: 200910018514.9) uses a universal joint to connect the transmission shaft and the film roll, so that the angle between the central axis of the film roll and the horizontal plane can be adjusted to adapt to the Ridges with different angles, but the film rolling roller is easy to entangle with the mulch film during the film winding process and it is difficult to unload the film, which affects the film winding effect

At the same time, the existing method of removing the film by directly contacting the furrow with the film rolling roller is easy to damage the tobacco leaves, it is difficult to unload the film from the film rolling roller, it cannot achieve long-term continuous film collection, large volume, and high power. The machine is still not perfect
