Description

Simple film laminating device

Technical Field

The utility model belongs to the technical field of farming, and particularly relates to a simple film mulching device.

Background

The mulching film is usually a transparent or black PE film, is used for covering the surface of the land, effectively increases the heat accumulation amount, overcomes the adverse natural conditions of low-temperature drought, water loss and the like, has obvious effects of increasing the yield and income of crops, and is used in a large range. The plastic film mulching cultivation technology is one of the main cultivation modes in most mountain tobacco areas in China, after a plastic film is covered on ridge bodies of the tobacco areas, the temperature, moisture and nutrient conditions of soil layers at the roots of tobacco seedlings can be obviously improved, the growing period of tobacco is shortened, in addition, the plastic film has the light effect and the weed prevention effect, the bad state of the original bare ground cultivation can be changed, and the growth, the yield, the quality and other economic characters of the tobacco are promoted.

However, in the prior art, most of the tobacco regions are still in a manual film covering mode due to the special terrain environment of the tobacco regions in the mountainous region, namely, one person holds two ends of a plastic film reel with two hands and covers the plastic film on the ridge body while advancing, and one person covers the local soil in the furrow at two ends of the plastic film by means of tools such as a hoe and the like and compresses and compacts the plastic film. At present, although there is the patent report to solving current plastic film mulching problem, no matter be tobacco field tectorial membrane ware or electronic laminating machine, all be applicable to large-scale level land parcel, to the sloping field that has certain slope, still have the inconvenient problem of operation, can't really reach and reduce the work and fall this purpose.

Chinese patent No. CN210959690 discloses a simple and easy tectorial membrane instrument, which comprises a mounting bracket, a plurality of gyro wheels of even installation on the diapire of mounting bracket, one end is fixed with the handle, then demountable installation has the installation roller on the mounting bracket, evenly around there being plastic film on the installation roller, install movable formula matched with pinch roll with it in the front of plastic film, the both ends of pinch roll are equipped with the pivot, the one end that the handle was kept away from to the mounting bracket is equipped with the earthing device of mutually supporting with plastic film, but this tectorial membrane instrument is bulky, be not convenient for transport and small size tobacco field use, the flexibility ratio is relatively poor, to the peasant household of non-scale planting tobacco, still there is the cost too high, carry inconvenient scheduling problem. Therefore, the simple film mulching device is suitable for small planting operation in the tobacco zone of the mountainous region, replaces a manual film mulching mode, and is an important means for solving the problem of power and time consumption of film mulching in the tobacco zone of the mountainous region.

SUMMERY OF THE UTILITY MODEL
