Abstract
The utility model discloses a device for adjusting the height of a tractor chassis. The device comprises a chassis, wherein a diesel engine is arranged on the chassis and is connected with an input shaft of a speed reducer through a belt; an output shaft of the speed reducer is connected with a transmission shaft through a bevel gear; the transmission shaft is connected with a driving shaft through the bevel gear; a driving wheel is arranged at each of two ends of the driving shaft; a shaft sleeve is sleeved outside the output shaft of the speed reducer; one end of the shaft sleeve is fixedly connected with a box body of a reduction box, and the other end of the shaft sleeve is movably connected with one end of a transmission shaft box body; the transmission shaft box body can rotate around the shaft sleeve; the other end of the transmission shaft box body is connected with an oil cylinder rod through a pin hole; and an oil cylinder is connected with a support on the chassis through the pin hole. The oil cylinder rod is stretched and retracted to drive the transmission shaft box body to rotate properly, so that the height of the tractor chassis is adjusted, the device can adapt to different working environments and working requirements, and the travelling efficiency and safety of the tractor are improved.
Description
Technical field
The utility model relates to trac., i.e. the tractor chassis arrangement for adjusting height.
Background technology
At present, the height of tractor chassis is all fixed, the position of drive wheel and the relative height on chassis just can't change after dispatching from the factory, but, trac. is walked in the rural area, ground often height is low, rugged, operation in the field, the mud pin is deep mixed, navigating mate wishes that the chassis of trac. can regulate with the different demand of the out-of-flat of landing ground, the depth of paddy field mud pin, various agricultural machinery working etc. the height of tractor chassis, to increase validity and the safety of trac. operation.
Summary of the invention
In order to adjust according to the demand of different operating environments and different work the height of tractor chassis, the utility model proposes a kind of tractor chassis arrangement for adjusting height.
This tractor chassis arrangement for adjusting height, comprise the chassis, diesel engine is housed on the chassis, diesel engine links to each other by the input shaft of belt and reductor, the output shaft of reductor links to each other with transmission shaft by crowngear, transmission shaft links to each other with axle drive shaft by crowngear, drive wheel is equipped with at the axle drive shaft two ends, it is characterized in that, the output shaft overcoat of reductor has axle sleeve, and the casing of axle sleeve one end and drop-gear box is captiveed joint, one end of the axle sleeve other end and transmission shaft casing is flexibly connected, the transmission shaft casing can rotate around axle sleeve, and the other end of transmission shaft casing links to each other with cylinder rod by pin-and-hole, and oil cylinder links to each other with the chassis upper bracket by pin-and-hole.
Selvage is equipped with in the bottom, chassis, and several lockholes are arranged on the selvage, is fixed with a lock ring on the transmission shaft casing, the height different according to drive wheel, the lockhole of diverse location is corresponding on lock ring and the selvage, is inserted with lock in lock ring and the lockhole, and the height of transmission shaft casing and axle drive shaft is fixed.
When needing the rising chassis, allow cylinder rod stretch out, transmission shaft casing, axle drive shaft and drive wheel are descending, when dropping to correct position, allow lock ring on the transmission shaft casing and certain lockhole on the selvage to good, plug pin and just can walk; When needs reduce the chassis, extract pin, allow cylinder rod retract, lift on transmission shaft casing, axle drive shaft and the drive wheel, when rising to correct position, allow lock ring on the transmission shaft casing and certain lockhole on the selvage to good, plug lock and just can walk.
The utility model is flexible by cylinder rod, can make the suitable rotation of driving axle box body, thereby adjusts the height of tractor chassis, can adapt to different working environments and the demand of operation, has increased efficient and safety that trac. travels.
