Description
Technical field
The utility model relates to agriculture ploughing machine, refers to that particularly the dual-purpose straw-returning of a kind of floods and droughts ploughs whole rotor.
Background technology
Agricultural crop straw is the Main By product that forms in agricultural production process, is one of important renewable biological source.Now, along with the development of rural economy, stalk is being not main fuel, for convenient plantation second stubble crop, people carry out on-site incineration, not only contaminated air to stalk, but also making soil compaction, the spoiled soil structure causes soil fertility to descend and ploughs and worsens.Straw-returning has the raising soil organic matter content, increases soil nutrient, reduces fertilizer amount, improves the benefits such as soil physical and chemical property and quality.
In recent years, in order to solve the straw-returning technical problem, people have developed some and have made the machinery of straw-returning, as practical new patent ZL99248205.4 " two roller tillage machine for recycling stalk to farmland ", its working portion comprises that rotor is pulverized in front rotary tillage and rear rotary tillage covers rotor, acting in conjunction by both realizes straw chopping and returning, and power consumption is large, mechanical load heavily waits problem but exist.Utility model patent ZL00226608.3 " rotovator that the straw-returning function is arranged ", it adopts belt to drive the cutter shaft of workpiece rotary tillage tulwar, producing because load is excessive skids makes stalk can not normally go back the problem in field yet be prone to.Utility model patent ZL200710141508.3 " paddy-field stubble-embedding rotary cultivator " arranges one and presses stubble to roll at the coulter shaft rear, press stubble to roll random rolling, the stalk under rotary tillage is pressed in earth, but exists power consumption large, and mechanical load is heavy, grass easy to hang, the problems such as band grass.Utility model patent ZL200820041185.0 " straw cutting apparatus ", mainly by gear-box, frame, framework lateral plate and be arranged on respectively the stalks cutting machine for covering grass structure on framework lateral plate and the pressure grass flattening mechanism that is arranged between framework lateral plate forms, realize a tractor serves several purposes, improve the availability of large and medium-sized tractor, but the stalk coverage rate is not high.Utility model patent ZL200820066760.2 " suspension type multipurpose farmland tillage working machine ", designed the monomer-type assembled cutter head that can be combined into one and carry out operation according to different agriculture requirements and the perching knife that loosens the soil, loosen the soil tulwar or other soil-engaging component, the workpieces such as extension spring damper, split type pack roller have been increased, can complete simultaneously the farmland and plough cultivated rake, the stubble-cleaning have suffered in journey, bury the agronomy multiple operations such as grass, suppression, soil moisture conservation, but have the problem that cutter head structure is complicated, the stalk coverage rate is low.Utility model patent ZL200820214707.2 " straw burying rotavator in paddy field " can complete the functions such as the paddy field stalk is buried, hack, stalk covering, but after farming, the grading degree is not high.
Summary of the invention
The purpose of this utility model will overcome the existing deficiency of prior art exactly, provides the dual-purpose straw-returning of a kind of floods and droughts to plough whole rotor.
for achieving the above object, the designed dual-purpose straw-returning of floods and droughts of the utility model is ploughed whole rotor, comprise cutter shaft, be arranged on the outer cutterhead at cutter shaft two ends and be arranged on a plurality of interior cutterhead and tool rest on cutter shaft, all be equipped with many outer tulwar on the both sides end face of the inner face of described outer cutterhead and interior cutterhead, be provided with the horizontal cutter of spiral between outer tulwar on described outer cutterhead and interior cutterhead opposing end surface, described every 50 ~ 60 sawtooth that evenly distribute on the cutting edge of the horizontal cutter of spiral, described tool rest by the helix mode around being arranged on described cutter shaft, interior tulwar is housed on described tool rest.Like this, tool rest is looped around on every joint cutter shaft by the helix mode, the horizontal cutter of this layout and spiral is coordinated, the continuity that in guaranteeing on tool rest, tulwar is cut soil, stalk and soil are sequentially cut and demarcate in advance, be beneficial to follow-up spiral rotor and soil and stalk are carried out rotary tillage turn over and bury, can make stressed more balanced simultaneously.
In such scheme, described interior cutterhead evenly is divided into two joints with the cutter shaft between cutterhead outside two ends, long 310 ~ the 340mm of described every joint cutter shaft, the rotary orientation of the horizontal cutter of spiral on every joint cutter shaft is identical, the rotary orientation of the horizontal cutter of spiral on adjacent two joint cutter shafts is different, and the lead angle of the horizontal cutter of described spiral is 20 ° ~ 30 °.Cultivation width can save on the basis two as required to be increased by joint number.
Further, described tool rest is looped around on every joint cutter shaft and is furnished with 5 rows, often arranges and puts 3 or 4 tool rest.
Further, 5 identical outer tulwars all are installed on the both sides end face of the inner face of described outer cutterhead and interior cutterhead.
Further, the outer face of described outer cutterhead is respectively apart from described cutter shaft outer face 90 ~ 130mm.
Further, described cutter shaft is provided with outer cutterhead, interior cutterhead or tool rest place diameter is 40 ~ 50mm.
The beneficial effects of the utility model are:
1, the dual-purpose straw-returning of the utility model floods and droughts is ploughed whole rotor and is adopted with the horizontal cutter of serrate spiral and in an orderly manner soil cutting is become box-shaped with inside and outside tulwar on being arranged on cutter shaft, and can be with Straw Kneading broken and be embedded in equably plow layer; The stalk that is buried under soil has been accelerated the speed of corroding, and can more organicly provide for soil, reduces the fertilizer application amount.
2, cultivated its average tilling depth of whole rotor of the dual-purpose straw-returning of the utility model floods and droughts is 120mm, after adding case, hanger bracket and pallet arrangement, use with tractor, can once complete and press stalk, rotary tillage, play slurry, bury the multiple tracks integration of operation operations such as stalk, hack, level land, reach second stubble crop comprehensively and broadcast the agriculture requirement of cultivation, its cultivating quality obviously is better than traditional rotovator, realizes a tractor serves several purposes.
3, the basic working width of the cultivated whole rotor of the dual-purpose straw-returning of the utility model floods and droughts is 700mm, can be designed to the serial facility of different fabric widths, a high stubble stalk that extensively is suitable for southern and northern paddy field, nonirrigated farmland directly buries and covers the also whole operation of Tagayasu Den, and what operation effectiveness can satisfy lower batch of floods and droughts crop fully broadcasts the cultivation requirement.
