Description
Technical field
The invention belongs to agricultural machinery, relate generally to the transformational structure of carrying out land wheel job state and travel position on a kind of large-scale farm implements.
Background technology
Along with increasing substantially of China's scientific and technological level and level of farming mechanization, the farm machinery of large-scale wide cut operation comprise that large-scale wide cut sower, tillage equipment etc. are in China, especially in the reclamation area, Heilungkiang with applied widely in the agricultural machinery cooperative society inside the province.In order to guarantee safety, trafficability characteristic and the convenience of conversion transportation between large-scale wide cut farm machinery transportation and operating area; Generally all adopt collapsible frame design; Facility fabric width when reducing to transport, obviously complex structure, the manufacturing cost height of folding facility are its outstanding technical bugs; Another kind of means of transportation is the longitudinal traction that adopts along large-scale wide cut farm machinery girder, and longitudinal traction need be equipped with the special-purpose support chassis of a cover and accomplish, and very inconvenience of execute-in-place.
Summary of the invention
The object of the invention is exactly the problem that exists to above-mentioned prior art; Design provides a kind of large farm machinery land wheel job state and travel position transformational structure; Through original ground wheel assembly on the large-scale wide cut farm machinery being changed equipped structure on support assembly; The ground wheel assembly is become can support assembly be raise in the farm machinery transportation, again can make ground wheel assembly half-twist, the hauling operation land wheel parallel with the support assembly girder, reach the purpose of simplifying the conversions of large-scale wide cut farm machinery structure, convenient working and travel position, conversion operations simple and convenient.
The objective of the invention is to realize like this: be hinged symmetrically through interior hollow pin on the crossbeam install two on balance arm, on interior hollow pin both ends, freewheel clutch and power output sprocket are installed respectively, duplicate sprocket fits on the freewheel clutch admittedly; Hollow pin is hinged separately respectively a land wheel frame is installed on passing through on the balance arm on two, and tower intermediate chain wheel is installed on the hollow pin; Two following balance arm upper ends that the bottom is hinged together each other through following hollow pin respectively with two land wheel frames in a land wheel frame hinged; On each land wheel frame bottom, passive pawl dish axle is installed in parallel to each other with last hollow pin, following hollow pin; The passive pawl dish that has drive sprocket is fitted on the passive pawl dish axle, and driving chain is connected with tower intermediate chain wheel, tower intermediate chain wheel on two land wheel frames drive sprocket respectively with duplicate sprocket; But the vertical shaft on each land wheel frame bottom side, through the ground wheel assembly is installed in ground wheel assembly horizontal direction on the land wheel frame rotationally; Connection chain drive assembly on the land axle of ground wheel assembly; The driving claw dish that has sprocket wheel is installed on the chain drive assembly upper lateral part; The chain drive assembly is connected land axle with the driving claw dish, the driving claw dish inserts snap fit each other or breaks away from passive pawl dish and cooperates; Stop pin axially pull is fitted on the land wheel frame following side movably, and cooperates with the vertical shaft locking latch of ground wheel assembly, so far constitutes large farm machinery land wheel job state and travel position transformational structure.
The present invention is with original ground wheel assembly on the large-scale wide cut farm machinery; Renewal through structural design changes; Become large-scale wide cut farm machinery transportation ground wheel assembly again easily, have that structural design is new reasonable, simple in structure, cheap, conversion is convenient, the service-strong characteristics.

Embodiment
Below in conjunction with accompanying drawing the embodiment of the invention is described in detail.A kind of large farm machinery land wheel job state and travel position transformational structure; Be hinged symmetrically through interior hollow pin 11 on the crossbeam 1 install two on balance arm 2; Freewheel clutch 13 and power output sprocket 17 are installed respectively on interior hollow pin 11 both ends, and duplicate sprocket 12 fits on the freewheel clutch 13 admittedly; Hollow pin 3 is hinged separately respectively a land wheel frame 5 is installed on passing through on the balance arm 2 on two, and tower intermediate chain wheel 4 is installed on the hollow pin 3; Two following balance arm 7 upper ends that the bottom is hinged together each other through following hollow pin 6 respectively with two land wheel frames 5 in a land wheel frame 5 hinged; On each land wheel frame 5 bottom with last hollow pin 3, hollow pin 6 is installed passive pawl dish axle 8 in parallel to each other down; The passive pawl dish 15 that has drive sprocket 9 is fitted on the passive pawl dish axle 8, and driving chain is connected with tower intermediate chain wheel 4, tower intermediate chain wheel 4 on two land wheel frames 5 drive sprocket 9 respectively with duplicate sprocket 12; But the vertical shaft 20 on each land wheel frame 5 bottom side, through ground wheel assembly 10 is installed in ground wheel assembly 10 horizontal directions on the land wheel frame 5 rotationally; Connection chain drive assembly 19 on the land axle 18 of ground wheel assembly 10; The driving claw dish 14 that has sprocket wheel is installed on chain drive assembly 19 upper lateral parts; Chain drive assembly 19 is connected land axle 18 with driving claw dish 14, driving claw dish 14 inserts snap fit each other or breaks away from passive pawl dish 15 and cooperates; Stop pin 16 axially pull is fitted on land wheel frame 5 following sides movably, and cooperates with vertical shaft 20 locking latch of ground wheel assembly 10.
Large farm machinery when travel position is changed, under the hydraulic jack power drive, descends crossbeam 1 and operation part through last balance arm 2 from job state; Under operation part supports, make wheel assembly 10 disengaging ground, ground, extract stop pin 16; Ground wheel assembly 10 is rotated 90 ° on land wheel frame 5, and parallel with the crossbeam 1 of support assembly, this moment, driving claw dish 14 cooperated with passive pawl dish 15 disengagings; Continuing, you lock on land wheel frame 5 with two ground wheel assemblies 10 of stop pin 16 with rear side, and two ground wheel assemblies 10 of front side do not lock, and are in servo-actuated free pendulum state; Through last balance arm 2 crossbeam 1 and operation part are risen in the lump again; Disengaging contacts with ground, and ground wheel assembly 10 is contacted with ground, can carry out vertical tractive hauling operation of large-scale wide cut farm machinery.
