Description
Technical Field
The invention relates to an agricultural operation machine, in particular to a straw crushing mechanism and a combined operation machine for crushing straw and recycling mulching films.
Background
The mulching technology has the functions of heat preservation, water conservation, soil moisture conservation and the like, can improve the crop yield in arid areas and cold areas, and certainly increases the crop yield in arid areas of Xinjiang or even nationwide lack of water. However, with the continuous popularization of the mulching technology, the white pollution is also serious, but the mulching film is accumulated in a large amount in the soil due to untimely recovery, especially untimely recovery or incomplete recovery of the mulching film at the end of each planting season, the soil structure is seriously damaged, and crop yield reduction is caused.
The current mulching film recycling mainly comprises the following modes.
Manual film collection has large workload and high working strength, and the labor cost increases year by year, so that manual recovery cannot adapt to the development of the agricultural planting industry, and mechanical recovery becomes a necessary way.
However, the existing residual film recycling machine has the common problems of poor operation stability, more recycling impurities, high working energy consumption and the like.
Current mulch recovery is mainly focused on after autumn crop harvest.
In recent years, straw returning is performed while mulching film recycling, so that the novel development trend is realized, pollution can be reduced, and soil can be effectively nourished.
The traditional mulching film recovery and straw returning are carried out through two stages, namely, the mulching film is recovered firstly and then the straw returning is carried out, so that two working procedures are not needed, and the production cost is increased to a great extent. Straw crushing and returning machine as disclosed in CN 205546552U.
The straw crushing and returning and residual film recycling combined operation machine disclosed in CN103782681A and CN103650675A performs one-time combined operation on straw crushing and returning and residual film recycling, but when the operation machine crushes straw, mulching films are easily rolled into the straw and brought back into the soil, so that the soil is polluted.
CN105900592a discloses a combined machine for recovering mulching film by crushing straw and returning to field, which protects mulching film by a frame or a plate-shaped film pressing and protecting member when crushing straw, but the frame or the plate-shaped film pressing and protecting member drags on the ground, is very resistant to straw, is easy to damage the mulching film, and causes difficulty in recovering the mulching film later.
In addition, the above-mentioned plastic film recovery mechanism all need consider the height and the dynamics of straw crushing time mechanism when smashing the straw to straw operation when smashing, and the height is too low, can harm and roll into the straw with the plastic film in, and the height is too high, and the incomplete stubble of straw of stay can influence plastic film and retrieve, and the speed is too fast, also can take the plastic film up when straw is smashed.
To solve the problems, the straw crushing mechanism and the combined machine for crushing and returning the straw and recycling the mulching film, which are formed, can effectively protect the mulching film during straw crushing, can adjust the operation force of the crushing mechanism and the stubble of the straw to be optimal, can effectively prevent the mulching film from being rolled in by the crushing mechanism or the straw, and further improve the operation effects of straw crushing and mulching film recycling, are generated.
