Axle bed is built with the 3rd anti-dust seal on fast case.
Oil cylinder in the hydraulic jack system is connected with bogie arm card and bogie arm respectively, the effect of hydraulic jack system
It is to allow oil cylinder upper and lower end with bogie arm card and bogie arm seat board hinge, to stretch oil cylinder piston by fluid pressure line and valve body respectively
Contract to change bogie arm and the built-in distance separated between claw main clutch, while drive equipment to raise, the hydraulic jack system
Unite as known technology;
Described ground wheel assembly, be by the oblique rubber tire tires of 6.5-12 by Interal fixation on land axle wheel hub, land axle both sides installation
There is bearing block, be separately fixed on bogie arm side plate, the sprocket wheel on land axle is connected by chain with underdrive sprocket wheel in arm card,
The passing power when land wheel rotates, it is known technology.
The clutch linkage assembly, it is one end and the fixation axis connection being fixed on bogie arm seat board, one end passes through pin
Axle and connecting plate hinge, when effect is the distance change between bogie arm and main clutch, pulls slide handle and drive slip
Set rotates together, so that spring supports slip cap return when axle is disconnected on disengaging pawl axle and gearbox or combines.
The built-in separation claw main transmission clutch assembly is seeder transmission and cuts off power critical component, mainly
It is core component by axle on gearbox and the disengaging pawl axle being engaged therewith, and slip cap and fixed seat is housed outside, slip cap is with consolidating
Reservation is engaged, and is assembled in and is slided inside block set.Slide block set, fixed seat, bearing block and bogie arm card to fit together, for closing
Mechanism, it is ensured that the safety and reliability of transmission.Axle both ends pass through first bearing seat and second bearing seat, axle respectively on gearbox

Support, end is pressed with return spring.Slip cap external stability have sliding panel and with clutch linkage assembly hinge.
Operation principle
The present invention be equipment in operation process, the land axle in ground wheel assembly is rotated by chain-driving transmission sprocket, become
Fast case sprocket wheel drives on gearbox axle to rotate again, while the clutch claw axle that axle is engaged therewith on gearbox also concomitant rotation, from
Hexagonal hole drives six square shafts of main transmission to rotate inside clutch pawl axle, and sowing mechanomotive force purpose is transmitted so as to reach.Both sides land wheel
Transmission mechanism is the same, both can synchronously use, also can independent passing power.
When no-tillage precision seeder transfer plot or headland turn need not transmit power, it need to only be made by hydraulic system
Equipment is risen used in bogie arm card and bogie arm upper cylinder, clutch linkage assembly can drive slip cap to rotate simultaneously, by cunning
Clutch claw axle in dynamic set separates with axle on gearbox, so as to cut off the power for being transmitted to six square shafts, reaches power separation purpose.
Now land axle only drives transmission sprocket to dally.
Equipment is fallen by hydraulic jack system when starting sowing to rand, while in built-in separation jaw clutch
Clutch pawl axle is under clutch linkage assembly and spring effect further in conjunction with reaching transfer motion power purpose.
