Description
Technical Field
The invention relates to the technical field of agricultural mechanical equipment, in particular to a self-rotating film picking roller type all-tillage-layer residual film recycling machine and a residual film recycling method.
Background
The mulching film has the functions of improving the surface temperature and humidity, inhibiting the growth of weeds, promoting the development of plant roots and improving the drought resistance of crops, greatly improves the yield of the crops and has important significance on agricultural production. However. With the application of the plastic film mulching technology, because of the absence of perfect matching recovery mechanical equipment, a large amount of residual films cannot be recovered and disposed, and the residual films are usually turned to the lower side of the soil. The quantity of residual films in the soil is accumulated year by year, and the soil quality of the soil and the growth environment of crops are seriously influenced. After crops are sown, if seeds fall on residual films of soil, root systems of the crops are difficult to grow downwards after germination, the root systems grow shallowly, the root bottoms are unstable in the middle and later growth periods, seedlings are prone to lodging, and crop yield is reduced. Even more, the residual film affects the normal operation of some mechanized agricultural implements, such as: the seeding machinery causes the blockage of seeding holes because of excessive residual films in soil, seeding is uneven, the quality is low, and manual replanting is needed after seedling emergence in the later period.
At present, the residual film recovery technology mainly aims at recovering the surface film and the residual film within 10cm of ploughing depth, and a recovery method for the residual film accumulated in soil in the past year is lacked. On one hand, the residual film is seriously differentiated and has poor mechanical property all the year round, and the residual film is seriously crushed after the soil preparation operation, so that the mechanical recovery difficulty is high; on the other hand, the residual film is mixed, hardened and wound with soil, stubbles and the like in the deep buried ploughing layer, so that the difficulty of recovery is further increased. Therefore, the problem of residual mulch recycling is not well solved, and the research and development of a technical method and a mechanism for effectively recycling the plough layer residual mulch still remain the core for realizing the pollution control of the full plough layer residual mulch.
Through retrieval, the residual film recycling technology has long-term development, and due to different thicknesses and strengths of mulching films used at home and abroad, great differences exist in the research aspect of residual film recycling machinery. The foreign mulching film used has the thickness of more than 0.020mm, has higher tensile strength and breakage resistance, and is beneficial to film-soil separation and mechanical recovery, so that the foreign residual film recovery machine has a simpler structure; the thickness of the domestic mulching film is 0.008mm, the mulching film is small in thickness and poor in quality, and the mulching film is easy to break and form small fragments during recycling, so that foreign residual film recycling machines are not suitable for solving the problem of residual film pollution in China.
The existing agricultural residual film recycling equipment in China is numerous in number, different in type, relatively single in function, poor in agricultural machine quality, general in use performance, relatively low in overall recycling rate and large in effect difference. The method is divided according to the agricultural requirements and the time of film collection, and can be roughly divided into pre-sowing and post-ploughing recovery, seedling-stage residual film recovery, and post-autumn recovery machines. According to the pick-up principle, the existing residual film pick-up machine mainly comprises a spring tooth type, a telescopic rod tooth type, a rake type, a shovel type stubble pick-up type, a toothed chain type, a spike tooth type, a clamping type, a film pick-up roller type, a comb tooth type, a chain sieve type, a chain rake type and the like.
Wherein, the main recovery mechanisms such as cone-shaped roll-type and chain type that are used for incomplete membrane of seedling stage to retrieve, though, its simple structure, compactness, it is unsatisfactory to the recovery effect of garrulous membrane to pick up membrane mechanism among the actual field test process, pick up the membrane tooth and can't snatch garrulous membrane or garrulous membrane phenomenon that drops takes place occasionally in transportation process, the incomplete membrane piece that is little still has more residue in ploughing when ending incomplete membrane recovery operation, and recovery effect is unsatisfactory. Meanwhile, sundries are easily brought into the membrane picking mechanism, and difficulty is brought to membrane impurity separation.
The mechanism for recovering the residual mulch after autumn mainly comprises a spring tooth type mechanism, a telescopic rod tooth type mechanism, a shovel type stubble lifting mechanism, a rake type mechanism and the like, the design and manufacture requirements of a curve track of the working position of the spring tooth type mechanism are high, and the residual mulch cannot be effectively separated from weeds by adopting the mode; the telescopic rod type ground film residual film picking device has good effect of picking up thick ground films, but has low picking rate for thin ground films and high failure rate of machines; the shovel type stubble lifting shovels the residual films together while lifting the stubble, and the soil and stubble separation is carried out through the squirrel-cage type rotary drum, so that certain requirements on soil properties are met, and the consumed power is high.
The chain screen type mechanism is used for ploughing and then recovering before sowing and after ploughing, and mainly comprises mechanisms such as a chain screen type mechanism, a spike-tooth type mechanism, a comb-tooth type mechanism and a rake type mechanism, when the chain screen type mechanism works, an inner film and soil on a plough layer are shoveled and conveyed to a chain screen for soil film separation, the traction resistance of the machine is large, and the picked small residual films are easy to fall along with soil blocks; the spike-tooth type mechanism adopts a mode that a film pinning pin is arranged on a roller to take the residual film, the residual film in a deep ploughing layer of a farmland can be recovered, spike teeth are easy to deform, the film is difficult to unload, and the clean picking rate is low; when the comb-tooth type mechanism is used for picking up, the comb-tooth cutter is pricked into soil to prick up residual plough layer films, the resistance of the comb teeth to the soil is large, the maximum operation depth is 100mm, and the comb-tooth type mechanism is loaded in operation and is not suitable for hardened soil; the chain harrow type mechanism adopts a chain to be provided with film picking teeth, the rotation of the chain drives the film picking teeth to dig in and pick up films, the picking depth is 100mm at most, and the digging roller cutter digs and crushes soil, so that the working efficiency of the whole machine is lower.
In summary, how to design a device for recovering the residual film in the process of recovering the residual film is to facilitate the complete separation of the residual film from the soil, reduce the difficulty of picking up and separating the residual film in the cultivation layer, and improve the recovery efficiency of the residual film and the picking-up rate of the residual film, which is a technical problem to be solved urgently by those skilled in the art.
