Description
Technical field
The utility model relates to agricultural machinery technological field, is specifically related to a kind of straight connected tractor and hangs 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.Another Chinese patent ZL2013205036886 of the applicant " trac. rear-mounted transmission gearbox ", from the side output shaft of change speed gear box by chain by transmission of power to middle driving box, again the imported agricultural machinery and implement of direct-connected power such as rotovator are fixedly connected on to the rear end of middle driving box, and by hydraulic ram, promote the lifting of middle driving box, so both meet the power demand of the imported agricultural machinery and implement of direct-connected power, there is again the hanging function of common hanger bracket.But this trac. rear-mounted transmission gearbox is appointed and is so had area for improvement: the one, and cannot coordinate direct-connected output type change speed gear box to use; The 2nd, arrangement of clutch is arranged between middle driving box and agricultural machinery and implement, along with the position of the lifting clutch handle of agricultural machinery and implement changes, misoperation easily occurs; The 3rd, the position of power-transfer clutch defines the length of middle driving box, as oversize in middle driving box, and clutch handle, away from operator's saddle, is controlled inconvenience.
Summary of the invention
The purpose of this utility model be to provide a kind of rational in infrastructure, power transmission route is short, control easily straight connected tractor hangs transmission gearbox, to coordinate rear power output speed changing box to use.
In order to reach above object, the technical scheme that the utility model adopts is: this straight connected tractor hangs transmission gearbox and comprises clutch-bell cover, is inserted into clutch handle on clutch-bell cover, is arranged on the clutch spindle in clutch-bell cover, the two ends of described clutch-bell cover are fixedly connected with oil cylinder seat, the end of clutch spindle is hinged on the front end of swing arm, the rear end of described swing arm is fixedly connected with hanger bracket, between described hanger bracket and oil cylinder seat, is provided with hydraulic ram; The mouth of clutch spindle is installed with sprocket wheel.
Transmission gear and slippage wheel are installed on described clutch spindle, and described transmission gear is slidably mounted on clutch spindle, and described slippage wheel can axially movably be arranged on clutch spindle by spline, and transmission gear and slippage wheel are in transmission connection by dental inlay clutch mode; On described slippage wheel, shift fork is installed, described shift fork is connected to clutch handle by connecting lever.
The two ends of described clutch-bell cover are respectively fixedly connected with a seat board, and a transverse axis is set between two seat boards, and one end of described hydraulic ram is hinged on the stage casing of transverse axis, and hydraulic ram is vertical with transverse axis to be arranged.
The beneficial effects of the utility model are: rational in infrastructure, power transmission route is short, control conveniently, can coordinate rear power output speed changing box to use.
Accompanying drawing explanation
Fig. 1 is the structural representation of an embodiment of the utility model.
Fig. 2 is the structural representation that Fig. 1 embodiment overlooks direction.
Fig. 3 is the structural representation of use state.
The specific embodiment
As shown in Figure 1, straight connected tractor described in the utility model hangs transmission gearbox and comprises clutch-bell cover 1, is inserted into clutch handle 2 on clutch-bell cover 1, is arranged on the clutch spindle 8 in clutch-bell cover 1.As shown in Figure 2, transmission gear 9 and slippage wheel 10 are installed on described clutch spindle 8, described transmission gear 9 is slidably mounted on clutch spindle 8, can rotate freely; Described slippage wheel 10 can axially movably be arranged on clutch spindle 8 by spline, can move axially and can not rotate.Transmission gear 9 and slippage wheel 10 are in transmission connection by dental inlay clutch mode, and when slippage wheel 10 moves and makes after dental inlay interlock to transmission gear 9, slippage wheel 10 is with transmission gear 9 in conjunction with interlock, and when slippage wheel 10 leaves transmission gear 9, both are separated; On described slippage wheel 10, shift fork is installed, described shift fork is connected to clutch handle 2 by connecting lever.Handle clutch handle 2 and can control the movement of slippage wheel 10.Certainly, in clutch-bell cover 1, also can adopt other clutch structures, its object is all to make transmission gear 9 and the mouth of clutch spindle 8 become the output of controollable power.
As shown in Figure 1 and Figure 2, the two ends of described clutch-bell cover 1 are fixedly connected with oil cylinder seat 3, and the end of clutch spindle is hinged on the front end of swing arm 4, and the rear end of described swing arm 4 is fixedly connected with hanger bracket 5, between described hanger bracket 5 and oil cylinder seat 3, are provided with hydraulic ram 6; The mouth of clutch spindle is installed with sprocket wheel 7.The farm implements of rotovator are directly installed on hanger bracket 5.
The two ends of described clutch-bell cover 1 are respectively fixedly connected with a seat board, and a transverse axis is set between two seat boards, and one end of described hydraulic ram 6 is hinged on the stage casing of transverse axis, and hydraulic ram 6 is vertical with transverse axis to be arranged.
As shown in Figure 3, during use, clutch-bell cover 1 is directly installed on to the rear end of gear box of tractor 11, transmission gear 9 and the power gear 12 in change speed gear box 11 are meshed, by power gear 12 band nutating gears 9 rotations.Between sprocket wheel 7 and farm implements sprocket wheel, chain is installed, by sprocket wheel 7, is driven the farm implements such as rotovator to work.Bar handle 2, makes slippage wheel 10 and transmission gear 9 drive clutch spindle 8 rotations in conjunction with passing through transmission gear 9, thereby drives farm implements to work by sprocket wheel 7.
In the time of hydraulic ram 6 work, can promote swing arm 4 and swing up and down, raise or reduce the height of hanger bracket 5, realize the lifting action of farm implements.
