Description
Technical field
The utility model relates to a kind of improvement of speed changing box for walking tractor structure.
Background technique
Hand tractor is a kind of common farm machinery, and for existing hand tractor because its horsepower small, manipulation is cumbersome, damage
Bad rate is high, the factors such as maintenance complexity in farmland operation by denouncing, it is practical and be friend peasant but because its is economical and practical
Indispensable a kind of agricultural machinery and implement.
The patent No. 201621007030.6, title are the utility model patents of " speed changing box for walking tractor ", are provided
A kind of easy to operate, horsepower is big, and driving force is big, is hardly damaged, and repairs easy speed changing box for walking tractor；In use, from case
The positive third axis hole of body stretches out output shaft, provides power by output shaft for tractor；At the rear portion of tractor, usually also need
Install some agricultural machinery and implement additional；These agricultural machinery and implement usually will also individually be equipped with power-equipment, since the output shaft of existing cabinet is set
It is placed in cabinet front, can not be matched with the power input shaft of agricultural machinery and implement, this results in the raising of agricultural machinery and implement equipment cost.
In addition, the octal of the gearbox is proximate to the front end of cabinet, after gearbox rear portion mounts agricultural machinery and implement, cause whole
Rearward, it is excessive that agricultural machinery and implement fall into depth of soil to the center of gravity of a tractor and agricultural machinery and implement, increases tractor by resistance, improves energy
Consumption, working efficiency are low.
Summary of the invention
The utility model provides a kind of center of gravity forward rear output speed changing box for walking tractor aiming at the above problem.
In order to realize the above-mentioned purpose of the utility model, the utility model adopts the following technical solution, the utility model packet
Cabinet is included, tank surface is provided with first shaft hole, the second axis hole, third axis hole, the 4th axis hole, the 5th axis hole, the 6th axis hole,
Seven axis holes and the 8th axis hole, it is characterised in that: the 9th axis hole is provided with below the third axis hole, after the 9th axis hole and cabinet
The delivery outlet in portion is corresponding；Lower part is provided with the tenth axis hole between 9th axis hole and the 7th axis hole.
As a kind of preferred embodiment of the utility model, the distance between the first shaft hole and the second axis hole center of circle a are
76.49 ± 0.04mm, the distance between the second axis hole and the third axis hole center of circle b are 72.11 ± 0.04mm, third axis hole and the 4th
The distance between axis hole center of circle c be 84.04 ± 0.05mm, the distance between first shaft hole and the 4th axis hole center of circle d be 96.21 ±
0.05mm, the distance between the second axis hole and the 4th axis hole center of circle e are 81.15 ± 0.05, the 4th axis hole and the 5th axis hole center of circle
The distance between f be 89.99 ± 0.05mm, the distance between the 5th axis hole and the 6th axis hole center of circle g be 100.77 ± 0.05mm,
The distance between 6th axis hole and the 7th axis hole center of circle h are 120.85 ± 0.05, between the 7th axis hole and the 8th axis hole center of circle
Distance i is 125.75 ± 0.05, and the distance between the 7th axis hole and the 9th axis hole center of circle j are 128.5 ± 0.05mm, third axis hole
The distance between tenth axis hole center of circle k is 84 ± 0.05mm.
The utility model has the beneficial effects that 1, the utility model, which passes through, increases by the tenth axis hole, but output shaft is after cabinet
Portion is stretched out, easy to connect so as to directly be connected with agricultural machinery and implement, without using other equipment, reduces the equipment cost of agricultural machinery and implement.
2, the utility model is by increasing by the 9th axis hole, after installing larger magnet-wheel in the 9th axis hole, since it is set to
Lower section between 7th axis hole and the tenth axis hole moves backward the center of gravity of entire gearbox；So as to cause entire tractor and
The center of gravity of agricultural machinery and implement moves forward, and making agricultural machinery and implement is not in fall into the too deep situation of soil, reduces tractor resistance, and reduction is dragged
Machine drawing energy consumption, it is energy saving.
3, the utility model is tested by repetition test, obtains the best hole location on cabinet, the utility model both ensure that
Gear driving force it is optimal, and advanced optimize the center of gravity of hand tractor, achieve the effect that energy efficiency.
