Abstract
The utility model relates to a hydraulic driving mechanism of a tea leaflet cutter, and belongs to the technical field of agricultural machinery. The hydraulic driving mechanism of the tea leaflet cutter comprises a lifting frame which is in movable connection with machine frames. A tea leaflet cutter is arranged on the lifting frame. A reciprocating mechanism of the tea leaflet cutter is in transmission connection with a hydraulic motor through a coupler. The hydraulic motor is connected with a hydraulic pump and a hydraulic oil tank through hydraulic pipelines. A control valve is in series connection with the hydraulic pipelines. The hydraulic pump, the hydraulic oil tank and the control valve are all arranged on the machine frames. The hydraulic driving mechanism of the tea leaflet cutter has the advantages of being flexible in adjustment, long in continuous operating hours and the like. The hydraulic driving mechanism of the tea leaflet cutter is suitable for being used in a self-propelled tea-picking machine.
Description
Technical field
The utility model relates to a kind of electric tea clippers hydraulic drive mechanism, belongs to agricultural machinery technological field.
Background technology
At present, multiple tea picking machinery has been arranged, wherein used the most general with shuttle electric tea clippers.The existing machinery of picking tea-leaves substantially all be backpack or hand lift formula, equipment moves forward against manpower in the operation process, so for weight reduction, the reciprocating motion of electric tea clippers generally adopts motor or put-put to drive.Although it is comparatively general that these two kinds of type of drive are used, and all has separately drawback: the powered battery that motor-driven relies on can not the long-time continuous operation, and the charge storage ability of accumulator reduces greatly along with the increase meeting of charge and discharge cycles number of times; And if petrol engine driving employing is rigidly connected, engine need be relative fixing with the position of electric tea clippers, and engine also needs along with movement when adjusting the electric tea clippers height, cause lift adjustment mechanism heaviness; And it is low to adopt flexible axle to connect transmission efficiency, has increased the system power loss.The defective of existing type of drive is lifted on the formula tea picking machine and can also be accepted general backpack or hand, but for large-scale self-propelled tea picking machine, but its performance requirement is picking mechanism height flexible modulation, but and the long-time continuous operation, existing type of drive has become the bottleneck of the large-scale self-propelled tea picking machine development of restriction.
The utility model content
The technical problems to be solved in the utility model is, but but proposes the also electric tea clippers hydraulic drive mechanism of long-time continuous operation of a kind of flexible modulation.
The utility model is that the technical scheme that solves the problems of the technologies described above proposition is: a kind of electric tea clippers hydraulic drive mechanism, comprise the crane that is flexibly connected with frame, electric tea clippers are installed on the crane, the reciprocating mechanism of electric tea clippers is connected with hydraulic motor transmission by shaft coupling, hydraulic motor is connected to hydraulic pump and hydraulic oil container by conduit under fluid pressure, be in series with control valve on the conduit under fluid pressure, hydraulic pump, hydraulic oil container and control valve all are located on the frame.
Preferably, hydraulic pump is unidirectional variable pump.
Electric tea clippers hydraulic drive mechanism of the present utility model is compared existing drives structure, and the beneficial effect that has is:
1, hydraulic motor drives by the static pressure of hydraulic oil, has a flexible rubber tubing and conduit under fluid pressure is optional, and the hydraulic motor size that satisfy to drive the electric tea clippers power requirement is much smaller than the size with the engine of power, so that the governor motion load of electric tea clippers is less, and flexible adjustment.
But 2, the power source flexible choice of hydraulic pump for example can drive the power that hydraulic pump provides hydraulic drive mechanism by the sustainer of self-propelled tea picking machine, and the time of working continuously is long.
3, can carry out stepless speed regulation to the reciprocating motion of electric tea clippers behind the unidirectional variable pump of employing.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the hydraulic system sketch of the utility model embodiment one.
Fig. 2 is the partial structurtes schematic diagram of figure the utility model embodiment one.
Fig. 3 is the vertical view of Fig. 2.
Embodiment
Embodiment one
The hydraulic system sketch of the electric tea clippers hydraulic drive mechanism of present embodiment as shown in Figure 1, comprise hydraulic pump 1, hydraulic motor 2, control valve 3, conduit under fluid pressure 4 and hydraulic oil container 10, wherein hydraulic motor 2 is connected to hydraulic pump 1 and hydraulic oil container 10 by conduit under fluid pressure 4, and control valve 3 is connected on the conduit under fluid pressure 4.Hydraulic pump 1, hydraulic oil container 10 all are located on the frame with control valve 3.
The end that hydraulic drive mechanism is positioned at electric tea clippers comprises and crane 8 that frame 9 is flexibly connected that as shown in Figures 2 and 3 electric tea clippers 7 are installed on the crane 8, and the reciprocating mechanism 6 of electric tea clippers 7 is in transmission connection by shaft coupling 5 and hydraulic motor 2.
Above-mentioned reciprocating mechanism is the mechanism that this area public affairs are directly known, by eccentric wheel the rotation of hydraulic motor 2 is converted into the dislocation campaign of blade in the electric tea clippers 7,
During use, the motion of electric tea clippers is to be controlled by the control valve 3 break-make oil circuits of hydraulic drive mechanism, comprises three kinds of modes of operation of switching and direction.
Further, the hydraulic pump in the above-mentioned fluid power system can adopt unidirectional variable pump, realizes the stepless speed regulation to electric tea clippers.
The above only is preferred embodiment of the present utility model, as long as adopt the technical solution of the utility model, perhaps modification or the equivalent variations made based on conventional means on it of those skilled in the art all drops in the protection domain of the utility model requirement.
