Abstract
The invention relates to a gear interlocking mechanism for an agricultural machinery gearbox. The gear interlocking mechanism comprises a first gear-engaging rocker arm (1), a second gear-engaging rocker arm (2), a gearbox cover (3), a guide plate (4), an interlocking pin (5), a first gear poking rod (6) and a second gear poking rod (7). The gear interlocking mechanism is structurally characterized in that the first gear-engaging rocker arm (1) and the second gear-engaging rocker arm (2) are installed on the gearbox cover (3) respectively through the first gear poking rod (6) and the second gear poking rod (7), and the interlocking pin (5) is assembled on the gearbox cover (3) through the guide plate (4). The interlocking pin is not subject to limitation of the distance of two shifting fork shafts and whether the shifting fork shafts move, and the applied range is expanded. By bi-directional sliding of the interlocking pin in a first locking groove of the first gear-engaging rocker arm and a second locking groove of the second gear-engaging rocker arm, interlocking limiting is performed, and the goal of preventing a gearbox gear mess is achieved.
Description
Technical field
The present invention relates to a kind of agricultural machinery change speed gear box gear interlocking mechanism, belong to agricultural mechanical field.
Background technology
Agricultural machinery change speed gear box gear usually not mutual interlocking gear on domestic market, due to the level of operator
Differ or many people operation, often result in machinery and disorderly keep off phenomenon.Or some mechanical has mutual interlocking gear, this mutual interlocking gear can only be applied
In close together and transportable two shift fork axles arranged side by side when putting into gear, it is contained in the arc groove of shift fork axle by interlocking pin end
Interior, rely on shift fork axle mobile drive interlocking plunger when putting into gear to realize interlocking；It is distant that this kind of mechanism cannot be applied to two shift fork axles
Or shift fork axle does not move and on the agricultural machinery change speed gear box of shift fork movement, range of application is restricted when putting into gear.Special invention is a kind of
Agricultural machinery change speed gear box gear interlocking mechanism, is contained on gear shift cover, whether is not subject to two shift fork axle distances and shift fork axle
The restriction of movement, prevents change speed gear box from disorderly keeping off.
Content of the invention
It is an object of the invention to provide a kind of agricultural machinery change speed gear box gear interlocking mechanism, solve to be subject in prior art
The problem that gearbox designs limit.
In order to reach above-mentioned purpose, present invention employs following technical scheme, agricultural machinery change speed gear box gear interlocking machine
Structure, mainly by rocking arm of putting into gear, rocking arm of putting into gear, gear shift cover, guide plate, interlocking plunger, gear driving lever, gear driving lever group
Become, rocking arm of putting into gear, rocking arm of putting into gear are contained on gear shift cover by gear driving lever, gear driving lever respectively；Interlocking plunger passes through
Guide plate is assemblied on gear shift cover.
Described rocking arm of putting into gear is provided with locked groove.
Described rocking arm of putting into gear is provided with locked groove.
It is provided with gathering sill in described guide plate.
Described interlocking plunger is installed in gathering sill, and one end is placed in the locked groove of rocking arm of putting into gear or the locked groove of rocking arm of putting into gear
Interior.
Due to present invention employs said structure, interlocking plunger is not subject to two shift fork axle distances and whether shift fork axle move
Limit, expand range of application.Meanwhile, double with the locked groove of rocking arm of putting into gear in the locked groove of rocking arm of putting into gear by interlocking plunger
To slip, carry out interlocking spacing, reach the purpose preventing the random gear of change speed gear box.
Brief description
Accompanying drawing 1 is a kind of change speed gear box gear interlocking mechanism front view.
Accompanying drawing 2 is a kind of change speed gear box gear interlocking mechanism sectional view.
Put into gear rocking arm, 2- of 1- puts into gear rocking arm, 3- gear shift cover, 4- guide plate, 5- interlocking plunger, 6- gear driving lever, 7-
Gear driving lever, 8- locked groove, 9- gathering sill, 10- locked groove.
Specific embodiment
For the present invention describe in detail and technology contents, cooperation brief description as follows, but accompanying drawing only provide reference with
Purposes of discussion, is not used for the present invention is any limitation as.
Below in conjunction with the accompanying drawings 1, accompanying drawing 2 a kind of specific embodiment of present invention change speed gear box gear interlocking mechanism is made into
One step description: when put into gear rocking arm drive gear driving lever swing put into gear when, interlocking plunger 5 in the presence of rocking arm of putting into gear
Slide in the gathering sill 9 of guide plate 4, slide in the locked groove of rocking arm of putting into gear, cause rocking arm of putting into gear can not swing and put into gear；When
When rocking arm of putting into gear returns to neutral position, its locked groove is aligned with the gathering sill 9 of guide plate 4, and rocking arm of putting into gear could drive gear
Driving lever swings and is put into gear, and interlocking plunger 5 slides in the presence of rocking arm of putting into gear in the gathering sill 9 of guide plate 4, slides into extension
In the locked groove 10 of gear rocking arm, cause rocking arm of putting into gear can not swing and put into gear；When rocking arm of putting into gear returns to neutral position, its lock
Groove is aligned with the gathering sill 9 of guide plate 4, and rocking arm of putting into gear could drive gear driving lever to swing and be put into gear；In sum, lead to
Cross the way moving of interlocking plunger 5, realize putting into gear rocking arm spacing with the interlocking of putting into gear of rocking arm of putting into gear, reach the mesh preventing disorderly keeping off
's.
The foregoing is only presently preferred embodiments of the present invention, be not used to limit the scope of the claims of the present invention, other are with this
The equivalence changes of the patent spirit of invention, all should all belong to the scope of the claims of the present invention.
