Description

Traction-driven mulch recycling machine

technical field

The invention relates to the technical field of tobacco planting film recycling equipment, in particular to a traction-driven plastic film recycling machine.

Background technique

Mulching cultivation started in the rainy regions of southern Japan. Since this technology was introduced into my country, it has been vigorously promoted in tobacco agricultural production. According to incomplete statistics, so far, the area covered by tobacco plastic film in my country has accounted for about 70% of the total tobacco planting area. It has developed into a tobacco cultivation industry. An important technical measure. This paper mainly expounds the beneficial and some unfavorable effects of film mulching in tobacco leaf production, and puts forward how to make reasonable use of film mulching measures in field production of tobacco leaves to improve the yield and quality of tobacco leaves.

Film mulching cultivation has the following advantages:

First, the insulation effect. After the plastic film covers the ridge body, because the plastic film blocks the long-wave radiation and heat convection of the soil in the ridge, it maintains the balance between the evaporation of water in the soil and the condensation of water droplets under the plastic film, thereby reducing the loss of heat and playing the role of heat preservation.

Second, the effect of water storage and moisture conservation. On the one hand, the mulching film restricts the evaporation of soil moisture, and at the same time, the evaporated water condenses into water droplets and returns to the soil, reducing the loss of soil moisture; on the other hand, the mulch film prevents a large amount of rainwater from entering the soil during rainfall. The relative content of soil moisture is kept stable, creating a good environment for the growth of tobacco plants.

Third, improve soil physical and chemical properties and improve soil nutrient status. Plastic film mulching is beneficial to reduce the phenomenon of soil compaction and bulk density increase caused by rain erosion, and maintain the loose state of the soil. In addition, since mulching increases the temperature and moisture content of the soil, it is more conducive to the decomposition and transformation of soil and fertilizer nutrients, and improves the availability of soil nutrients.

Fourth, it can effectively control some pests and weeds. Due to the use of mulching film, the microenvironment of the soil has been changed, and the source of infection and transmission route of the disease have been effectively controlled.

Fifth, it can promote the growth and development of tobacco and increase economic output. Plastic film mulching improves the soil environment. For the underground part, it is beneficial to the growth of the root system of the tobacco plant. For the aboveground part, the tobacco plant grows faster in the early stage, which can increase the yield of tobacco leaves.

However, due to the high cost of degradable films, farmers are unwilling to accept them. Therefore, the agricultural films used are mainly ordinary PVC plastic films. Because they cannot be degraded, they will cause serious pollution to the soil if they are left in the field. The growth is hindered, the water is isolated, and the seedlings will wither and die in severe cases. Throwing plastic film residues in the field will also cause waste of resources. The effect is poor, resulting in unclean recovery of residual film.

Contents of the invention

The invention provides a traction-driven plastic film recycling machine aiming at the problem of incomplete film collection by the existing plastic film recycling machine.

In order to achieve the above purpose, the following technical solutions are adopted: a traction-driven mulch recovery machine, including a vehicle frame and a film grabbing mechanism. The film-grabbing roller is installed with a film-grabbing roller through a bearing on the roof beam, and the outer surfaces of the film-grabbing roller and the film-bonding roller are respectively provided with film-grabbing teeth and film-bonding teeth, and the film-grabbing teeth and the film-bonding teeth are arranged in a staggered manner; Drive wheel 1 and drive wheel 2 are installed on the rotating shaft of the ground wheel, and drive wheel 1 and drive wheel 2 respectively drive the film-grabbing roller and the film-bonding roller to rotate, satisfying: the speed of the ground wheel is smaller than the speed of the film-grabbing roller but greater than the speed of the film-bonding roller ; There is also a film-bonding transition plate, the side of the film-bonding transition plate close to the film-bonding roller is inclined or bent upwards, and a side-by-side relief groove is arranged on the inclined or curved edge, so that the film-bonding teeth can move from the corresponding relief groove. pass.

A membrane outlet channel is provided on the rear side of the membrane transition plate. A material receiving container is arranged below the outlet of the film outlet channel.

The periphery of the ground wheel is provided with nail-shaped ground teeth.

The grasping teeth or membrane-connecting teeth are arc-shaped or broken-line or arc-shaped. When adopting arc-shaped film-grasping teeth or film-connecting teeth, the arc directions of the film-grasping teeth and the film-connecting teeth are the same.

The direction of rotation of the grabbing roller and the splicing roller is the same.

Beneficial effects: the present invention increases the speed of the film-grabbing roller, so that the film-grabbing roller and the film-grabbing teeth can quickly grab the film on the spot, thereby increasing the times of film-grabbing and improving the grabbing rate. Reduce the speed of the film splicing roller, so that there is a speed difference between the film grabbing roller and the film splicing roller, so that there are multiple overlapping opportunities between the film grabbing teeth and the film splicing teeth, which is convenient to improve the success rate of film splicing. The low-speed rotating film splicing roller cooperates with the film splicing transition plate to realize the transfer of residual film. Tilting upward or bending the film-bonding transition plate to give way can go deep between the film-bonding teeth, and the residual film between the film-bonding teeth is scooped out and slides down to the film outlet channel. The invention has a simplified structure, is easy to process and manufacture, and is very beneficial to popularization and implementation.
