The front portion of box top is curved arch, adapts with the clutch in case, while saving material, reduces the volume of casing as much as possible; The rear portion of box top is horizontal plane, and arranges two raised lines in the horizontal plane, and be combined closely with the fitting seat of arm assembly by raised line, not only attended operation is convenient, and fixing and good stability, and arm assembly can be avoided to occur to loosen.The tank filler sleeve of box top is used for charging-up lubricant oil in case, and tank filler sleeve arranges the first annular boss, to sealing cover location, make sealing cover dismounting more convenient; The peep hole of casing right flank is used for the oil level information in user's inspection box, and peep hole place arranges the second annular boss, so that Mirror for indicating oil level location and assembling.The square delivery outlet of bottom half is used for Power output, makes gearbox by moment of torsion cultivated cutter transmission downwards.The positioning boss of the left and right sides, casing bottom is connected with frame by bolt, and such casing is easy for installation in frame, quick, is connected firmly, reliably.
In order to weight reduction, be convenient to processing and fabricating, and guarantee structural strength, described casing (1) is formed by aluminium alloy compression casting.
In order to ensure the fixing of positioning boss, described positioning boss (12) reduces gradually from root toward the direction of free end.
Rectangular boss (14) is provided with in the top of described peep hole (9), this rectangular boss (14) and casing (1) are structure as a whole, and rectangular boss (14) offer former and later two the 4th mounting holes (15).Rectangular boss is for being installed to casing by gear arm, and rectangular boss structure is simple, and fixing is good, is conducive to gear arm quick assembling.
In order to simplified structure, facilitate processing and fabricating, described raised line (16) is elongated rectangular shape, and is structure as a whole with casing (1).
Beneficial effect: the utility model arranges tank filler sleeve at gearbox casing top, and side arranges peep hole, can facilitate charging-up lubricant oil and conveniently observe oil level information; Gearbox casing and power assembly, arm assembly and frame fitting operation are easy, easy accessibility, and it is firm to connect; The utility model structure is simple, compact, and volume is little, lightweight, and easily, reforming cost is low, is conducive to microtilling machine to miniaturization, lightweight future development in transformation.
