Description
Technical field
The present invention relates to a kind of rice field ditching machine, belong to the farm machinery technical field.
Background technology
Carrying out the science water according to the paddy rice law of needing the water, is an important step capturing the rice high yield stable yields.Accomplish the science water, must possess two conditions: irrigation drainage channel separates outside (1) field, each upright door, and (2) are held the high yield ditch successfully in the field.So just can make the big specification of filling draining system and the small dimension of field water system form an organic whole, accomplish that train of thought communicates, Guan Shui freely.The high yield ditch can make rice root flourishing, live sturdy, heading is neat, grouting is full, very anti-resistant to lodging.Excavation high yield ditch is the experience of summing up in the 60 to 70's of eighties of last century, and the excavation of high yield ditch relies on manual operation always, and its working strength is big, and is very tired.In addition, at late growth stage of rice, if run into the more situation of wind and rain, also can lodge easily, its loss that causes is very big, and high yield ditch excavation helps the paddy rice lodging-prevention.Therefore, press for a kind of mechanization facility, replaced hand excavation's ditch of getting bumper crops.
Excavation high yield ditch operation condition: digging time generally tiller rice be near completion, after the rice field shallow water put and put the field; Being shaped as of high yield ditch is trapezoidal: according to different rice planting line-spacings, the base width requirement can be in 60～100mm range regulation, and the top width requirement can be in 180～220mm range regulation, and trench depth requires can be in 80～130mm range regulation; Require facility weight light and handy, be easy to carry.
Disclose a kind of ditching machine in " design of the small-sized ditching machine of paddy field " that " modern agriculture equipment " 8 interim woods Qi Kuan in 2009 etc. are shown, comprised plough, planker, engine, transmission mechanism and running gear composition, plough adopts the wheeled plough of rotation, and plough is located at front end; Running gear and transmission mechanism are arranged in the rear end, and planker plays support, balance and smooth effect, and above-mentioned design exists following not enough: at first; The plough design is comparatively heavy, and volume is bigger, needs enough power to drive; Secondly, arrange comparatively unreasonablely, the weight of rear end is much larger than the weight of front end; Cause that head is light and feet are heavy, need extraly come balance, increase design cost with planker; Light inadequately, last, the trapezoidal high yield ditch shape of falling cannot be accomplished.The document of ditching machine aspect is also disclosed in the existing patent documentation; Like the patent No. is the Chinese invention patent " ridging ditcher for both paddy field and dry land " (Granted publication number for CN1025768C) of ZL92108174.X; The ditching machine of this patent adopts shovel formula plough, exists resistance big, the deficiency of easy abrasion; And the overall weight layout is reasonable inadequately, seems top-heavy.Similarly can also application reference number be that 201010591483.9 Chinese invention patent application discloses " novel motor-driven single wheel ditching machine " (application publication number: CN102090170A).
