Because the above-mentioned defect of prior art, technical problem to be solved in the utility model is to provide two oil level cellular type gearbox of micro plowing machines that a kind of structure is simple, be easy to assembling.
The technical solution of the utility model is as follows: a kind of two oil level cellular type gearbox of micro plowing machine, there is casing (1), the uncovered back-end closure in front end of described casing (1), " ∩ " shape shirt rim (2) is formed with in the periphery of casing (1) front port, this shirt rim (2) is distributed with the first mounting hole (3), casing (1) ear end face has spindle hole (4) and countershaft hole (5), spindle hole (4) is positioned at directly over countershaft hole (5), and be provided with circumferentially equally distributed second mounting hole (6) in the periphery of the periphery of spindle hole (4) and countershaft hole (5), tank filler sleeve (7) is offered in the front portion of described casing (1) end face, the hole wall upwards one extension of this tank filler sleeve (7), form the first annular boss (8), the middle part of casing (1) right flank offers peep hole (9), the hole wall one extension to the right of this peep hole (9), forms the second annular boss (10), the bottom surface of described casing (1) offers square delivery outlet (11), and be symmetrically arranged with positioning boss (12) in the left and right sides of casing (1) bottom, the bottom surface of this positioning boss (12) is concordant with the bottom surface of casing (1), and positioning boss (12) offers the 3rd mounting hole (13) along the vertical direction.
Adopt above technological scheme, the shirt rim of casing front end is used for being connected with power assembly by flange plate, and not only attended operation is convenient, and the soundness connected is good; Shirt rim is " ∩ " shape, is connected as a single entity with casing, and structural strength is good, and shirt rim does not affect the planarization of tank floor, can not cause adverse effect to the installation of casing.The spindle hole of box back and countershaft hole are used for running in bearings and oil sealing, so that the supporting of main shaft, countershaft, and guarantee that main shaft, countershaft rotate flexibly; Second mounting hole of major and minor axis hole periphery is used for bolt and wears, so that be installed to securely on casing by dust cover.
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.
Beneficial effect: the utility model structure is simple, compact, and volume is little, lightweight, is conducive to microtilling machine to miniaturization, lightweight future development; Arrange tank filler sleeve at gearbox casing top, side arranges peep hole, can facilitate charging-up lubricant oil and conveniently observe oil level information; Gearbox casing and power assembly and frame fitting operation easy, easy accessibility, it is firm to connect.
