Technical Field
The utility model relates to an on-membrane soil covering device, which relates to an on-membrane intermittent soil covering device; belongs to agricultural machinery.
Background
The crops such as potatoes, peppers and the like are planted in a ridging and film covering mode. In order to ensure smooth seedling emergence or blocking holes on the transplanted mulching film, the mulching film is covered with soil with a certain thickness. If the film covering soil layer is too thick, the ground temperature can be reduced, and the potatoes emerge late; if the soil layer on the film is too thin, the bud top can not open the mulching film, and the seedling shortage is serious.
At present, the soil covering on the film mainly comprises two modes of manual soil covering and mechanical soil covering. The labor intensity of manual earthing is high, the efficiency is low, and the thickness of the covering soil layer is not uniform; the mechanical earth covering mainly comprises a drum type, a scraper conveyor belt type, a rotary tillage type and the like. The drum type soil covering machine (such as CN 210840918U) is used for guiding the turned soil into a soil covering roller through an obliquely arranged soil covering shovel, and then conveying the soil transversely through a spiral deflector fixed in the soil covering roller and covering the soil on a mulching film. A scraper conveyer belt type soil covering machine (such as CN 205694703U) conveys the shoveled soil into a soil box through an obliquely arranged scraper conveyer belt, then crushes the soil by a packing auger, transversely conveys the crushed soil and covers the ground film. The rotary tillage type on-film soil covering machine takes soil from the side of a mulching film through a rotary tillage cutter and transversely throws the soil on the mulching film.
The three membrane earthing devices all have the following defects:
1) large soil blocks cannot be broken, holes of the mulching film cannot be effectively blocked after earthing, and water is evaporated.
2) The soil is continuously and linearly covered (intermittent fixed-distance covering cannot be realized), the pressure on the mulching film is large, and the air permeability of the soil under the mulching film is poor.
3) The soil sampling device has no following adjusting mechanism which changes with the shape of the ground, can not realize quantitative soil sampling, and the thickness of the soil covered on the film is not uniform.
