Embodiment approach
[0025] An agricultural mulch, such as figure 1 As shown, it includes seed row area film 110 and non-seed row area film 110 arranged at intervals along its width direction and successively connected, the thickness of seed row area film 110 is smaller than the thickness of non-seed row area film 110, the adjacent seed row The distance between the centerlines of the area films 110 is equal to the row pitch. The position corresponding to the row is the seed row area film 110. The thickness of the seed row area film 110 is smaller than the thickness of the row spacing area film. It is convenient to break the film when sowing, and it is easy to be torn from the seed row area film 110 when the agricultural mulch film is recycled. The strip structure is convenient for recycling. After the seeds develop into plants, it is easy to pass through the seed row area film 110 from the lower part to ensure the smooth growth of the plants. At the same time, ensure that the thickness of the non...

The invention discloses an agricultural mulching film, a die head and an agricultural mulching film plastic extruding machine comprising the die head. The agricultural mulching film comprises plantingrow area films and non-planting row area films which are arranged in the width direction at intervals and connected in sequence; the planting row area films are smaller than the non-planting row areafilms in thickness; and the distance between the middle lines of the adjacent planting row area films is equal to the row distance. The die head comprises an outer ring and an inner disc which are fixedly connected; die orifices comprise planting row area die orifices and non-planting row area die orifices which are arranged at intervals and connected in sequence; and the planting row area die orifices are smaller than the non-planting row area die orifices in width. The agricultural mulching film plastic extruding machine comprising the die head further comprises two plastic extruding machines; a melting channel of one plastic extruding machine is connected with a planting row area melting channel; a melting channel of the other plastic extruding machine is connected with a non-plantingrow area melting channel; and the two plastic extruding machines each comprises a hopper, a power mechanism, a spiral propeller, a heating block, a traction mechanism and a film winding mechanism. Theagricultural mulching film has the beneficial effects of easy recovery and easy puncture from the lower part during developing of plants.
Description
technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to an agricultural mulch film, a die head and an agricultural mulch film extruder including the die head. Background technique [0002] Agricultural mulch, that is, ground covering film, is usually transparent or black PE film, and there are also green and silver films, which are used for ground covering to increase soil temperature, maintain soil moisture, maintain soil structure, and prevent pests from invading crops and certain microorganisms. Diseases, etc., to promote the function of plant growth. When the mulch film needs to be recovered from the ground when the crop grows or the climate becomes warmer, the mulch film is easily torn into irregular shapes due to the uniform thickness of the mulch film. Recycle. [0003] Therefore, there is a need for an agricultural mulch film that is easily recycled. Contents of the invention [0004] The object of the pres...
