Abstract
The invention discloses a tractor, and relates to the technical field of manufacturing of agriculture machines. The tractor comprises a front axle, a rear axle and a pull rod lifting device, wherein a vehicle frame is arranged on the front axle and the rear axle, and an axle box which is connected with an engine through a front power output shaft in a driving manner is mounted at the back end of the vehicle frame; and a lifting oil cylinder which is used for driving the pull rod lifting device to rise and fall is hinged on the axle box. Compared with the prior art, the lifting and the falling of an agricultural tool are realized by driving the pull rod lifting device through the lifting oil cylinder, the action of the pull rod lifting device of the tractor is fast, and the sensitivity is high.
Description
Technical field
The present invention relates to manufacture of agricultural machinery technical field, especially a kind of trac. with the raising rod device of individual drive.
Background technology
In agricultural production mechanization operation, trac. draws various agricultural machinery and implement by its suspension type and carries out operation; There is a kind of trac. as depicted in figs. 1 and 2, this trac. includes propons, back axle and driving engine 12, driving engine 12 is connected with rear axle box 11 by transmission shaft, and rear axle box 11 is provided with the walking power take-off shaft being connected with rear walking wheel actuating device, the spline output shaft 13 being connected with farm implements and exports the shaft drying raising rod device 14 being contained in rear axle box 11 by lifting drive.In use there is following deficiency in this trac.: 1, the power of driving engine outputs to rear axle box, by walking power take-off shaft, drive the trailing wheel of trac. to walk, simultaneously by spline output shaft by power transmission to farm implements, because being subject to the output torque of rear axle box structural limitations spline output shaft little, a little less than power; 2, the lifting of farm implements and decline drive raising rod device to realize by lifting drive output shaft, and lifting drive output shaft is one of three power take-off shafts of rear axle box, therefore often because the output torque of lifting drive output shaft is little, cause trac. raising rod device action slowly and sensitivity low.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of trac. with the raising rod device of independent driving device, to solve the slow and low problem of sensitivity of the raising rod device action of existing trac..
In order to address the above problem, the technical solution used in the present invention is: this trac., include propons, back axle and raising rod device, on described propons and described back axle, be provided with vehicle frame, the bridge case being in transmission connection by front power input shaft and driving engine is equipped with in the rear end of described vehicle frame; On described bridge case, be hinged with the elevating ram that drives the lifting of described raising rod device.
In above-mentioned trac. technical scheme, technical scheme can also be more specifically: described raising rod device comprises the lifting arm that is hinged on described bridge case and by pull bar and the hinged push rod of described lifting arm, described elevating ram is contained between described bridge case and described push rod.
Owing to having adopted technique scheme, the present invention compared with prior art has following beneficial effect:
1, the power of driving engine of the present invention outputs to bridge case, and the output shaft by bridge case is transferred to farm implements, and bridge case only has a power take-off shaft, so the moment of torsion of the power take-off shaft of bridge case is large, powerful; The lifting of farm implements and decline drive raising rod device to realize by elevating ram, and being swift in motion of the raising rod device of trac. is highly sensitive.
2, adopt elevating ram to control the lifting of raising rod device, simple in structure, back axle volume is little, saves installing space.
Accompanying drawing explanation
Fig. 1 is the structural representation of existing trac..
Fig. 2 is the birds-eye view of Fig. 1.
Fig. 3 is the structural representation of the embodiment of the present invention.
Fig. 4 is the birds-eye view of Fig. 3.
The specific embodiment
Below in conjunction with accompanying drawing embodiment, the invention will be further described:
A kind of trac. as shown in Figure 3, Figure 4, includes propons 1, back axle 3 and raising rod device, on propons 1 and back axle 3, vehicle frame 2 is installed, and the bridge case 5 being in transmission connection by front power input shaft 4 and driving engine is equipped with in the rear end of vehicle frame 2; On bridge case 5, be hinged with the elevating ram 6 that drives the lifting of raising rod device, elevating ram 6 connects fuel tank by Hydraulic Pump; Raising rod device comprises the lifting arm 7 that is hinged on bridge case 5 and by the hinged push rod 9 of pull bar 8 and lifting arm 7, elevating ram 6 is contained between bridge case 5 and push rod 9, and the piston rod of elevating ram 6 is connected with push rod 9.
The power of driving engine of the present invention outputs to bridge case 5, and the output shaft by bridge case 5 is transferred to farm implements, and bridge case 5 only has a power take-off shaft, so the moment of torsion of the power take-off shaft of bridge case 5 is large, powerful; The lifting of farm implements and decline drive raising rod devices to realize by elevating ram 6, and being swift in motion of the raising rod device of trac. is highly sensitive.
