There is following deficiency in above-mentioned this class rotovator: the driving force that needs are bigger, incompatibility fritter, the farming of irregular field are balked in operation inconvenience easily during turning.For this reason, there is improved rotovator open, see the patent No.: the Chinese utility model patent of ZL200920061342.9 " a kind of rotovator " (Granted publication number: 201491475U) with rear-guard power, this patent is arranged at the rotary tillage wheel before the road wheel, promptly adopt rear drive configuration, but engine still is arranged at the last front end of main body rack, pre-structure is the same with improving, this structure suits for farming such as rice fields, but for kinds such as the sort of nursery stock garden or orchard have shrub occasion, because rotovator head (being engine place part) volume is bigger, some place can not be passed through, and influences farming, " a kind of front positioning type rotary cultivator attachment " (Granted publication number: CN201467636U) open is arranged for this reason, see that the patent No. is the Chinese utility model of ZL200920188586.3, this patent has well solved the problems referred to above, but this patent adopts the multi-chain gear wheel transmission, volume is bigger, parts are more, and comparatively inconvenience is produced in assembling, and is easy in the use break down.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of production and assembly convenient and swift at the above-mentioned state of the art, simple and reasonable modularization front positioning type rotary cultivator attachment.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of modularization front positioning type rotary cultivator attachment is characterized in that comprising
Gear shaft, leading section have an active bevel gear;
Driving shaft, middle part have gear ring portion;
Gear-box, inside has accommodation space, and both sides have for driving shaft runs through the side ports of passing through, and rearward end has the rear port that passes through for aforementioned angular wheel,
Driven bevel gear is positioned at aforesaid gear-box, and have with the internal tooth of aforesaid gear ring portion engagement and with the external tooth of aforementioned active bevel gear engagement;
The rotary blade assembly has Rotary tillage blade, is sheathed on the aforementioned driving shaft and by this drive shaft to rotate;
Side bearing is two, is located at respectively on the side ports of aforesaid gears case, for aforementioned drive shaft turns; And
Rear bearing is located on the rear port of aforesaid gears case, rotates for the aforesaid gears axle.
For making the integrated and protection gear shaft of assembling, described gear-box rear port is connected with a connecting leg, and described gear shaft then is located in this connecting leg.
Further, described connecting leg bottom is provided with a damper rod, plays certain guide effect.
The power output spline of a described gear shaft rear end and a two-way modularized transmission box is in transmission connection, and the shell of described connecting leg rear end and aforementioned bidirectional modularized transmission box is connected and fixed.Can be assembled into one with bidirectional modularized transmission box, convenient and engine directly assembles.
Consider easy for installationly, described gear-box comprises casing and cover plate, and the leading section of aforementioned casing has the front port that stretches into for driven bevel gear, and aforesaid cover plate is then on the front port of the aforementioned casing in detachable ground.
Compared with prior art, advantage of the present utility model is: as the rotary tillage head, be directly arranged on the rotovator rack body, can farming be used for occasions such as orchard, nursery stock garden, the rotary blade assembly can waltz through the direct gap of shrub, and simultaneously, engine is arranged on rearward end rather than above the rotary blade assembly, so the requirement for height to the gap is lower, and is unaffected.The overall structure advantages of simple, integrated degree height.
