Abstract
The utility model relates to a rotary tiller for returning grain stalks to farm lands as fertilizer. The utility model is characterized in that the middle of a frame is provided with a transmission case, the left side and the right side of the transmission case are respectively provided with a knife roll assembly which comprises a knife roll body, a tool post welded on the knife roll body and a rotary blade positioned in the tool post, drive bearings are arranged between the knife roll body and the box-plates at two sides and simultaneously positioned in a bearing block, the bearing block connects with the box-plates, the outer edges of the bearing block at the inner sides of the box-plates are provided with grass winding proofing hoops fixedly arranged in the box-plates, 3 to 8 pieces of scraper bars are evenly positioned along the axial line of the knife roll body and fixed on the tool post, the space between the inner edges at the end of each scraper bar and the outer circumference of each grass winding proofing hoop is provided with a dynamic sealing grass winding proofing gap to prevent grasses from winding on an arbor. The outer edges of the scraper bars have a maximum rotary radius larger than the rotary radius of blade starting point of the rotary blade by 0cm to 10cm, thus, soil and slurry may cover grasses effectively. The utility model has the advantages of absent grass winding and availability of slurry (with a slurry depth of 3cm to 10cm) once being applied to operations of glebes and paddy fields respectively as well as ability of burying the pervious batch beneath soil, thereby enriching soil.
Description
Technical field
The utility model relates to a kind of farm machinery, the dual-purpose rotovator of returning crop stocks to the field of particularly a kind of multi-functional floods and droughts.
Background technology
Now along with the renewal day by day of science and technology, the improving constantly of agricultural mechanization degree and life of farmers level, the rural area nearly all is to use large-scale grain header when harvesting crops, the rural area also almost no longer utilizes straw, so straw is everywhere as seen in the ground, field.Rotovator of the prior art all is transmission in the middle of adopting, its rigidity is good, left-right symmetry, stress balance, reliable operation, be the main farm machinery of present soil cultivating, its deficiency is in: straw field also, and grass twines cutter shaft easily, strengthens the tractor load, cause the rotovator cisco unity malfunction, fall flat wholely.
Summary of the invention
The technical problems to be solved in the utility model is at the deficiencies in the prior art, has proposed dual-purpose, the anti-grass rotovator of returning crop stocks to the field that twines of a kind of floods and droughts.
The technical problems to be solved in the utility model is achieved through the following technical solutions, a kind of rotovator of returning crop stocks to the field, it is provided with transmission case at the middle part of frame, the rotor assembly is equipped with in the left and right sides of transmission case, the rotor assembly is contained between frame two side box plates and the transmission case, the rotor assembly comprises roller cutter body, be welded on the tool rest on the roller cutter body and be contained in the interior rotary blade of tool rest, be characterized in: between roller cutter body and two side box plates drive bearing is housed, drive bearing is contained in the bearing block, described bearing block is fixedlyed connected with boxboard, be provided with and the hard-wired anti-careless annulus that twines of boxboard in boxboard inner shafts bearing outer rim, be evenly equipped with 3～8 clean-up scrapers along the roller cutter body axis direction, clean-up scraper is fixed on the tool rest, and edge and anti-twining between the careless annulus cylindrical prevent twining careless gap for dynamic seal (packing) in the end of clean-up scraper.
The technical problems to be solved in the utility model can also come by the following technical programs further to realize that described dynamic seal (packing) prevents that twining careless gap is 0.1～8mm.
The technical problems to be solved in the utility model can also come by the following technical programs further to realize that the maximum radius of turn of clean-up scraper outer is than big a 0～10cm of sword point radius of turn of rotary blade.
The technical problems to be solved in the utility model can also come further to realize by the following technical programs, at the bearing cap that the boxboard outside is provided with and boxboard is fixing, is provided with and is fixed on the dust ring on the roller cutter body in boxboard inner shafts bearing and roller cutter body joint.
The technical problems to be solved in the utility model can also come further to realize by the following technical programs, describedly anti-ly twines careless annulus and is made up of two semicircles.
The utility model is equipped with clean-up scraper and is equipped with in the bearing block outer rim and anti-twines careless annulus on the rotor assembly, in the end of clean-up scraper along and anti-twining between the careless annulus cylindrical form dynamic seal (packing), make weeds can not twine cutter shaft.The maximum radius of turn of clean-up scraper outer is bigger than a sword point radius of turn of rotary blade in addition, and soil and mud can be covered on the weeds effectively.Compared with prior art, the utility model dry land operation cutter shaft straw winding, and can realize burying a batch effect effectively, and it is simple and practical, and it is effective to prevent twining grass.
