As we all know, plastic film mulching cultivation technology is an important technical measure of modern agricultural production, and it is a scientific cultivation technology with quick effect and high economic benefit.

Plastic film mulching machine is a machine for laying plastic film on the border or ground and sealing it.

Used for plastic film mulching cultivation of vegetables, peanuts, cotton, tobacco, melons and fruits.

So what are the plastic film mulching machines? Let's have a look.

What are the plastic film mulching machines?

Film laying machine

It is used to spread and seal the film on the prepared ridge or ridge.

You can spread the film first, and then punch holes in the film for sowing or transplanting; You can also sow the seeds first and then lay the film.

A simple film laying machine with manual traction consists of a bracket for loading plastic film rolls, a ditcher for digging a film burying ditch, a film pressing wheel for horizontally stretching the film and a film burying wheel for sealing and pressing the film. Simple structure, small and light parts, suitable for working in small plots or greenhouses and plastic greenhouses.

Animal traction film laying machine is suitable for sloping fields, terraces or small plots.

Its structure is based on a simple film laying machine, adding a film laying roller and a cup forming part.

The film laying roller can keep the longitudinal tension of plastic film to adapt to the operation in windy climate.

Ridge film laying machine

It consists of plowshare or scraper ditching device, ditch forming parts, film laying device and film burying wheel.

The ridging device ridges or ridges the cultivated land, the film spreading device spreads the film, and the film is sealed by the rolling action of the film burying wheel; Some are also equipped with herbicide spraying devices.

The invention can be matched with various tractors and used in the agricultural process of film mulching, drilling or transplanting first. Its operation quality is good, and it also has certain adaptability to soil with more gravel.

Rotary tillage film laying machine

It is a combination of rotary cultivator and plastic film mulching machine, which can complete rotary tillage, ridging, film mulching and film sealing at one time.

The operation quality is good, the adaptability is strong, and the border soil is fine and uniform, which is beneficial to soil and water conservation and can reduce the times of tractor stubble pressing.

Seeding and film laying combined machine

Mainly used for plastic film mulching cultivation of cotton, peanuts and other crops.

There are two kinds: one is sowing first and then spreading film, which consists of a film spreading device hanging on a seeder; The other is to lay film first and then sow, which consists of film laying device and special hole drilling and sowing device. It is used for laying flat film, punching holes, quantitative hole sowing, cultivating soil, covering seed holes and sealing plastic film on cultivated land at one time.

Some can also carry out many operations such as soil preparation, ridging, drilling, sowing, fertilization and spraying at the same time.

Working process of plastic film mulching machine

The types and structures of plastic film mulching machines are different, but the film laying process is basically the same.

The following mainly introduces the working process of furrow film laying machine and rotary tillage film laying machine.

Ridge film laying machine

Before film laying, lower the film laying machine to the working height, pull out a part of the film and bury it.

After starting, under the tractor's traction, the left and right soil collectors push the soft soil cultivated on the surface from both sides of the ridge to the middle, forming ridges and ditches.

The herringbone shaper divides the ridge soil into two sides to form the border and level it.

The bell-jar ditcher digs out the soil on both sides of the ridge according to the width requirements of the ridge, and ditches the plastic film.

Before film mulching, the roller compacts the border surface, crushes the clods, and presses hard objects such as stones into the soil on the border surface, which provides good conditions for film mulching.

The swing arm of the swing film hanging frame clamps the film and moves downwards as the film roll becomes thinner, so that the film roll always rolls forward along the frame to prevent the wind from blowing under the film during operation.

Brush-type film laying mechanism slides forward by gravity pressure on the film, longitudinally tightens the film, smoothes the wrinkles and plays a windproof role.

The film pressing wheel presses both sides of the plastic film into the plastic film groove, and the film laminating machine turns the soil inward to bury the plastic film.

The retaining plate can effectively control the depth of covering soil thrown into the boundary surface, thus ensuring the width of the lighting surface.

At this point, all film laying operations are completed.

Rotary tillage film laying machine

When the rotary cultivator works, the front rotary cultivator cultivates the soil, and the ridger and shaper at the back do ridge shaping.

Subsequently, the film is rolled on the boundary surface and spread out. After the film is rolled, the edge is compacted and the film is close to the soil. Film rollers on both sides roll up the film edge, cover the soil with a net mulcher, and compact and seal the film edge.
