High ridge plastic film mulching machine

Abstract

The invention relates to agricultural machinery for mulching a plastic film on ridge culture crops. A draw hook (9) and a front bracket wheel (2) are arranged at the front end of a small-specification steel pipe bracket (1); an opener (3) is arranged at the rear of the small-specification steel pipe bracket (1); a film expansion mechanism is formed by a film bearing frame (4), a film expansion roller (5), a film pressing wheel (6) and a torsion spring (8); and finally a covering device (7) is arranged. Due to the adoption of the special film expansion mechanism, the operation can be smooth to carry out when the plastic film is mulched for the ridge culture crops such as potatoes, ridge culture peanuts and the like in a protected field, the soil is uniform to cover, the plastic film has proper tightness degree, and the film surface is flat like a mirror. The agricultural machinery for mulching the plastic film on the ridge culture crops needs small traction power and can be operated by both women and children.

Description

technical field [0001] The invention relates to a plastic film covering machine, which is especially suitable for covering the plastic film with ridge-growing crops such as protected potatoes and ridge-growing peanuts. Background technique [0002] Mulching film covering potatoes and ridge-growing peanuts in protected areas is very different from other flat-cropping crops. The latter works on a plane, and the horizontal section after operation is a regular rectangle. It is enough to press the soil on both sides of the ground; the former operation object is a high ridge, the plane after the operation is tile-shaped, the cross-section is a few-shaped, the top of the ridge is a flat arc surface, the side of the ridge is a slope, and both sides are pressed into the ridge (see Figure 5 ), whose geometry is more complex. Most of the mulching machines currently on the market are flat mulching machines. It is difficult to ensure smooth operation and poor operation quality when usin...

[0002] Mulching film covering potatoes and ridge-growing peanuts in protected areas is very different from other flat-cropping crops. The latter works on a plane, and the horizontal section after operation is a regular rectangle. It is enough to press the soil on both sides of the ground; the former operation object is a high ridge, the plane after the operation is tile-shaped, the cross-section is a few-shaped, the top of the ridge is a flat arc surface, the side of the ridge is a slope, and both sides are pressed into the ridge (see Figure 5 ), whose geometry is more complex

Most of the mulching machines currently on the market are flat mulching machines. It is difficult to ensure smooth operation and poor operation quality when using it to cover high-ridge crops with mulch. In order to overcome its defects, the amount of embedding pressure has to be increased, thereby increasing the operation resistance. Large power must be used for traction; the large amount of embedding pressure increases the difficulty of cleaning the residual film during harvesting. The residual film is difficult to degrade in the soil, and if it accumulates too much, it will cause land pollution
