Abstract

The utility model discloses a rotary tillage gearbox for a machine with rotary tillage and seed covering functions, which comprises an input shaft, a transition shaft, an output shaft and a shift fork shaft arranged on a box body, wherein the rotary tillage gearbox can achieve two-stage speed changing through four fixed gears and a pair of clutch gears to meet the requirement for high-speed breaking and low-speed rotary seed covering of miniature rotary tilling machine. The gearbox is matched with the miniature tilling machine of 2 to 5 horsepower to achieve rotary tillage and seed covering functions, thereby enlarging the use range of the prior miniature tilling machine.

Description

The rotary tillage gearbox of miniature rotary tillage lid kind of dual-purpose machine

Technical field:

The utility model relates to a kind of miniature rotary tillage lid kind of dual-purpose machine, relates in particular to rotary tillage gearbox wherein.

Background technique:

Because carry out with the family in China rural area is the cropping pattern of base unit, for adapting to the needs of family oriented tillage method, people have designed multiple Miniature cultivator used on higher, its power is generally 2～5 horsepowers, and based on the arable land, often finish for rotary tillage by existing 12 type walk-behind type rotary cultivators, very inconvenient in actual cultivating procedure, for this reason, people have designed multiple miniature rotary cultivator, with the supporting use of Miniature cultivator used on higher, they have only a kind of rotary tillage speed, and its power drives the rotation of rotary blade group axle by the main transformer speed of Miniature cultivator used on higher by chain from the centre.This miniature rotary cultivator can only be used for simple rotary tillage and break ground, can't satisfy low speed rotation and cover the requirement of cultivating of planting, the gear shift function that does not possess existing 12 type walk-behind type rotary cultivators, people press for a kind of miniature rotary tillage lid kind of machine, wherein the most key rotary tillage lid kind of the gearbox that two retaining speed changes can be provided.

The model utility content:

Goal of the invention of the present utility model is: a kind of rotary tillage gearbox of miniature rotary tillage lid kind of dual-purpose machine is provided, it can with existing 2～5 horsepowers of supporting uses of Miniature cultivator used on higher, satisfy that rotary tillage is broken ground and the technological requirement of low speed rotation lid.

The technological scheme that the utility model is taked is:

The rotary tillage gearbox of described miniature rotary tillage lid kind of dual-purpose machine, comprise input shaft 1, transition axis 2, output shaft 3, declutch shift shaft 4, casing 5, input shaft bearing 6, output shaft bearing 7, input sprocket 8, output sprocket 9, empty cover clutch gear 10, slide engaging and disengaging gear 11, left gear 12, intermediate gear 13, right gear 14, output gear 15 and shift fork 16, left gear 12 fixedly is housed on transition axis 2, intermediate gear 13 and right gear 14, be sleeved on the input shaft 1 empty cover clutch gear 10 axial restraints, and be meshed with left gear 12 on the transition axis 2, slide engaging and disengaging gear 11 is sleeved on the spline segment of input shaft 1, when slide engaging and disengaging gear 11 is positioned at the limit on the right-right-hand limit position, intermediate gear 13 engagements on slide engaging and disengaging gear 11 and the transition axis 2, slide engaging and disengaging gear 11 relative input shaft 1 slips, empty cover clutch gear 10 is provided with the end face clutch structure with the corresponding face of slide engaging and disengaging gear 11, the clutch that realizes both with separate, output gear 15 is fixedly mounted on the output shaft 3, and be meshed with right gear 14 on the transition axis 2, the right-hand member of input shaft 1 is bearing on the casing 5 by bearing, its left side section is fixed on the casing 5 by input shaft bearing 6, input sprocket 8 is installed in the left end of input shaft 1, the two ends of transition axis 2 are bearing on the casing 5 by bearing, the left end of output shaft 3 is bearing on the casing 5 by bearing, right section is fixed on the casing 5 by output shaft bearing 7, output sprocket 9 is installed in the right-hand member of output shaft 3, declutch shift shaft 4 is fixedly mounted on the casing 5, shift fork 16 is sleeved on the declutch shift shaft 4, and corresponding with slide engaging and disengaging gear 11.

Because this gearbox has designed two retaining speed changes, it can satisfy, and high speed is broken ground and kind of the rotation requirement of low speed lid.The Miniature cultivator used on higher of this gearbox and 2～5 horsepowers is supporting, can realize rotary tillage lid kind of a double-purpose functional, can enlarge the using scope that has Miniature cultivator used on higher now.
