Abstract
The utility model discloses a kind of trac., relate to manufacture of agricultural machinery technical field, include propons, back axle and raising rod device, described propons and described back axle are provided with vehicle frame, the bridge case be connected with driving engine by front power input shaft is equipped with in the rear end of described vehicle frame; Described bridge case is hinged with the elevating ram driving the lifting of described raising rod device.Compared with prior art, the lifting of the utility model farm implements and descend through elevating ram and drive raising rod device to realize, being swift in motion of the raising rod device of trac., highly sensitive.
Description
Technical field
The utility model 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 be connected with rear walking wheel actuating device, the splined output shaft 13 be connected with farm implements and exports the shaft drying raising rod device 14 be contained in rear axle box 11 by lifting drive.In use there is following deficiency in this trac.: 1, the Power output of driving engine is to rear axle box, the trailing wheel walking of trac. is driven by walking power take-off shaft, simultaneously by splined output shaft by power transmission to farm implements, because the output torque by rear axle box structural limitations splined output shaft is little, power is weak; 2, farm implements lifting and descend through lifting drive output shaft and drive raising rod device to realize, and lifting drive output shaft is one of three power take-off shafts of rear axle box, therefore the normal output torque because of lifting drive output shaft little and cause the raising rod device action of trac. slowly and sensitivity low.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of trac. with the raising rod device of independent driving device, with solve the raising rod device action of existing trac. slowly and the low problem of sensitivity.
In order to solve the problem, the technical solution adopted in the utility model is: this trac., include propons, back axle and raising rod device, described propons and described back axle are provided with vehicle frame, and the bridge case be connected with driving engine by front power input shaft is equipped with in the rear end of described vehicle frame; Described bridge case is hinged with the elevating ram driving 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 and is hinged on lifting arm 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 have employed technique scheme, the utility model compared with prior art has following beneficial effect:
1, the Power output of the utility model driving engine is to bridge case, is transferred to farm implements by the output shaft of bridge case, and bridge case only has a power take-off shaft, and therefore the moment of torsion of the power take-off shaft of bridge case is large, powerful; The lifting of farm implements and descend through elevating ram and drive raising rod device to realize, being swift in motion of the raising rod device of trac., highly sensitive.
2, adopt elevating ram to control the lifting of raising rod device, structure is simple, and 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 utility model embodiment.
Fig. 4 is the birds-eye view of Fig. 3.
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the utility model is described in further detail:
A kind of trac. as shown in Figure 3, Figure 4, includes propons 1, back axle 3 and raising rod device, and propons 1 and back axle 3 are provided with vehicle frame 2, and the bridge case 5 be connected with driving engine by front power input shaft 4 is equipped with in the rear end of vehicle frame 2; Bridge case 5 is hinged with the elevating ram 6 driving the lifting of raising rod device, and elevating ram 6 connects fuel tank by Hydraulic Pump; Raising rod device comprises and is hinged on lifting arm 7 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 output of the utility model driving engine, to bridge case 5, is transferred to farm implements by the output shaft of bridge case 5, and bridge case 5 only has a power take-off shaft, and therefore the moment of torsion of the power take-off shaft of bridge case 5 is large, powerful; The lifting of farm implements and descend through elevating ram 6 and drive raising rod device to realize, being swift in motion of the raising rod device of trac., highly sensitive.
