Abstract
The utility model relates to the technical field of agricultural machinery, and particularly relates to a rear-suspension transmission box of a tractor. The rear-suspension transmission box comprises a box body, and a connecting plate hinged on the outer wall of the box body through a hinge shaft, wherein a hydraulic cylinder is arranged between the connecting plate and the box body; the transmission shaft is inserted in the box body, bearings are arranged at joints of two ends of the transmission shaft and the box body, a transmission gear is fixedly arranged on the transmission shaft positioned inside the box body, and a transmission chain wheel is fixedly arranged at the tail end of the transmission shaft positioned at the exterior of the box body. The rear-suspension transmission box is simple in structure, reasonable in design, short in power transmission line and high in efficiency, and can be used for directly suspending a direct-connection power input agricultural implement.
Description
Technical field
The utility model relates to agricultural machinery technological field, is specifically related to a kind of trac. rear-mounted transmission gearbox.
Background technology
At agricultural mechanical field, conventionally use again trac. as traveling gear simultaneously also as power take-off implement, trac. above or connect the actuating units such as rotovator, cropper below and complete concrete farmland operation task.Therefore, after trac., conventionally there is a hanger bracket to be used for connecting various agricultural machinery and implement.But existing hanger bracket has only been to provide linkage function, there is no transmission of power ability, the power pack section of actuating unit need to connect gear box of tractor with belt, and power transmission line is long, efficiency is low.Agricultural machinery and implement for some direct-connected power input as the rotovator with walking tractor matching, also need change structure just can hang use later.
Summary of the invention
The purpose of this utility model is to provide a kind of simple in structure, reasonable in design, power transmission route is short, efficiency is high trac. rear-mounted transmission gearbox.
In order to reach above object, the technical scheme that the utility model adopts is: this trac. rear-mounted transmission gearbox comprises casing, by hinge, is hinged on the connecting panel on cabinet exterior, is also provided with hydraulic actuating cylinder between connecting panel and casing; Transmission shaft is inserted in casing, and the junction of transmission shaft two ends and casing is provided with bearing, is positioned on the transmission shaft of box house and is installed with transmission gear, and the transmission the tip of the axis that is positioned at casing outside is installed with driving chain wheel.
Described connecting panel is provided with connecting panel axle sleeve, and the outer wall of described casing is provided with housing bushing, and described connecting panel axle sleeve and housing bushing are all sleeved on hinge.
The beneficial effects of the utility model are: simple in structure, reasonable in design, power transmission route is short, efficiency is high, can directly hang the imported agricultural machinery and implement of direct-connected power.
Accompanying drawing explanation
Fig. 1 is the structural representation of an embodiment of the utility model.
Fig. 2 is for connecting the structural representation of the imported rotovator of direct-connected power.
The specific embodiment
As shown in Figure 1, trac. rear-mounted transmission gearbox described in the utility model comprises casing 1, by hinge 2, is hinged on the connecting panel 3 on casing 1 outer wall, described connecting panel 3 is provided with connecting panel axle sleeve, the outer wall of described casing 1 is provided with housing bushing, and described connecting panel axle sleeve and housing bushing are all sleeved on hinge 2.Connecting panel 3 is for being fixedly connected on trac. rear end, and casing 1 can swing up and down in certain amplitude.Between connecting panel 3 and casing 1, be also provided with hydraulic actuating cylinder 4, utilize hydraulic actuating cylinder 4 can promote casing 1 and swing up and down; Transmission shaft 5 is inserted in casing 1, and the junction of transmission shaft 5 two ends and casing 1 is provided with bearing, and transmission shaft 5 can be rotated freely.Be positioned on the transmission shaft 5 of casing 1 inside and be installed with transmission gear 6, the end that is positioned at the transmission shaft 5 of casing 1 outside is installed with driving chain wheel 7.
As shown in Figure 2, during use, connecting panel 3 is arranged on to the position of the original suspension plate of four-wheeled tractor, and utilize chain that driving chain wheel 7 is connected with the power output sprocket of gear box of tractor, the imported agricultural machinery and implement of direct-connected power such as rotovator are fixedly connected on to the rear end of casing 1, make the power input gear 8 and transmission gear 6 engagements of rotovator.
At walking states, operation hydraulic actuating cylinder 4, raises casing 1, rotovator can be lifted.At operating condition, operation hydraulic actuating cylinder 4, reduces casing 1, and rotovator is put down, and gear box of tractor drives rotovator to work by driving chain wheel 7, transmission gear 6, power input gear 8.The imported rotovator of direct-connected power that rotovator can directly adopt original cooperation walker tractor to use.Its structure is prior art, at this, no longer describes in detail.
