Abstract
The utility model discloses a blade of a dentiform effective paddy field rotary cultivator, which consists of a knife back (1) and a knife body (2). The blade is characterized in that the length of the blade body is accordant with that of a rotary drum, the edge of the knife body is designed to be dentiform, and the shape of a tooth convex (3) corresponds to that of a tooth concave (4). The blade of the dentiform effective paddy field rotary cultivator has relative smaller single knife feeding quantity, reduces the required drive power, reduces the impact, can avoid drastic jump, is hard to be wound with grass, greatly improves the work efficiency, is convenient and fast in installation, and has long service life.
Description
Technical field
The utility model relates to a kind of farmland harvesting and tillage machine tool, the efficient paddy field rotary tillage machine knife blade of particularly a kind of profile of tooth.
Background technology
Along with cultivated adjusting technique progress, rotovator blade kind is more on the domestic market, and mostly be the blade of band radian, this blade for the ploughing of paddy field, bury, smooth make troubles more, in time, twines careless situation and takes place, and the someone adopts vertical bar shape blade to make the paddy field rotary tillage blade in recent years, is promptly having welding ordered series of numbers vertical bar shape blade on the cylinder of central axle sleeve, every columns blade is arranged along the in-line that is on the drum length direction same, is between the blade that in-line arranges to leave the gap.There is following defective in this blade, and the one, the hilted broadsword depth of cut is big when cultivated whole, needs bigger driving force, and very easily causes the violent impact and the defective of beating.The 2nd, straw or weeds wrapping phenomena very easily take place in the gap between the same column blade, and operating efficiency is reduced greatly.The 3rd, inconvenience is installed.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of driving power that needs less, impact mild, be difficult for twining grass, the efficient paddy field rotary tillage machine knife blade of profile of tooth easy for installation, long service life, the utility model is realized by following technical proposals: the utility model is made of the knife back and cutter hub, it is characterized in that cutter hub length is consistent with drum length, the edge of a knife of cutter hub is designed to dentation, and tooth is protruding corresponding with the mark of mouth shape.
Said tooth is protruding can be rectangle, trapezoidal or triangle any.
The edge of a knife one end of said cutter hub is that tooth is protruding, and the other end is a mark of mouth, arranges so that the protruding dislocation of tooth of two adjacent cutter hubs is installed on the back roll.
During use with the knife back directly with the cylinder outside of band central axle sleeve along the welding of shaft length direction, on cylinder, be provided with tool rest certainly, again by bolt and the rotary tillage cutter hub is affixed also can.The protruding dislocation of the tooth of two adjacent column is arranged, and promptly the previous column tooth is protruding corresponding with back one row mark of mouth.
The utility model compared with prior art has following advantage: the one, and the hilted broadsword depth of cut is less relatively, and required driving force reduces; The 2nd, impact gentlyer, can not occur acutely beating; The 3rd, be difficult for twining grass, also can cut even run into the stubble stake, improved operating efficiency greatly; The 4th, quick and easy for installation, long service life.
