Description
Technical field
But the present invention relates to a kind of avoiding-type that is used for the oil tea fruit picking machine and pluck mechanism.
Background technology
Oil tea is the important quality raw materials of vegetable oil, and its results have extremely strong seasonality, and for a long time, each oil tea plantation overwhelming majority relies on hand harvest oil tea fruit, and labour intensity is big, and efficient is low.In the prior art, China fails to address this problem always, and the development of oil tea fruit picking machine is just at the early-stage; Have the oil tea fruit picking machine to come out abroad, though mechanism's automaticity and operating efficiency are higher, yet mechanism is too complicated; And cost is too high, is not suitable for the present situation of China.China's oil tea fruit picking machine still need go into overdrive to develop.
Through to now having become the tea oil tree of the oil tea planting base of scale to study, it is bigger to find that tea oil tree has branch toughness, does not have fruit on the trunk of tea oil tree basically, and fruit mainly is distributed in the front end of tea oil tree branch.
Part is used for the picking mechanical of oil tea fruit, and in the harvesting process, when running into thicker branch, but that avoiding-type is plucked mechanism is then stuck easily, when running into this situation, often need stop the oil tea fruit picking machine, artificial branch is taken out, and influences picking efficiency.
Summary of the invention
Big to existing oil tea harvesting labour intensity, efficient is low; Be prone to stuck defective in the picking mechanical harvesting process of part oil tea, pluck mechanism but the present invention aims to provide a kind of avoiding-type that is used for the oil tea fruit picking machine, it runs into branch can avoid stuck; Picking efficiency is high; And easy to operate, practical, inter-agency coordination is functional.
For realizing above-mentioned purpose; The technical scheme that the present invention takes is: but a kind of avoiding-type that is used for the oil tea fruit picking machine is plucked mechanism, and its design feature is: comprise the left and right sides minor axis of the axle center conllinear that is fixed on the pedestal, on this left and right sides minor axis left and right sides support wheel is housed respectively; Left and right sides support wheel circumferentially is hinged with many crossbeams; Be arranged in juxtaposition many picking head on this crossbeam, said crossbeam one end is connected with connecting rod, and the other end of this connecting rod is hinged on the circumferential of secondary support wheel through pitman shaft; A centre of support is installed on the said pedestal, and secondary support wheel can rotate around this centre of support; Said left and right sides support wheel, secondary support wheel, connecting rod and pedestal have been formed a double-crank mechanism; The harvesting silk of said picking head is hinged on to be plucked on the guide frame, is fixed in the resilient U-shaped steel wire plucked on the guide frame with said a harvestings clamping.
Said centre of support comprises three bearing shaft, is contained in the deep groove ball bearing on the bearing shaft; One end of said bearing shaft is fixed on the bearing shaft fixed head, and this bearing shaft fixed head is fixed on the pedestal.
Circumferentially be hinged with three crossbeams on the support wheel of the said left and right sides, three crossbeams are symmetrical with respect to minor axis axial line center, the left and right sides.
Circumferentially be hinged with three connecting rods on the said secondary support wheel, the pitman shaft of three connecting rods is symmetrical with respect to secondary support wheel center line center.
Be connected with the harvesting guide frame on the said crossbeam, be provided with the resilient U-shaped steel wire in said harvesting guide frame one side, resilient U-shaped steel wire opposite side is provided with pressing plate, through bolt said harvesting guide frame, resilient U-shaped steel wire and pressing plate is fixed together; Said harvesting silk back segment places between the resilient U-shaped steel wire U-shaped, and is hinged on the harvesting guide frame through fixed axis, is convenient to pluck resetting of silk.Plucking the silk head adopts steel wire to curve claw type; Its tail end is welded with small circle ring, plucks silk and is hinged on the harvesting guide frame through fixed axis and small circle ring, limits the position of plucking silk by this structure; And when bearing certain force, pluck silk and can turn an angle again, can play the branch effect of avoiding.
Said left and right sides minor axis axial line equates to the distance of connecting rod with respect to the pitman shaft axial line of secondary gripper shoe rotation with the bearing shaft axial line to the distance of crossbeam axial line; Direction to guarantee each picking head is all identical; And the adjustable angle between picking head and the connecting rod, and angle that can be through regulating picking head and connecting rod is to reach the highest picking efficiency.
Left and right sides minor axis described in the present invention also can be replaced by a major axis.
But the avoiding-type of whole oil tea fruit picking machine is plucked mechanism and is installed on the oil tea fruit picking machine; Motion along with grain header; Power set drive a left side through power input shaft or/and right minor axis is left or/and right minor axis drive left and right sides support wheel rotates, and rotate around three deep groove ball bearings thereby drive secondary support wheel through crossbeam, connecting rod; Thereby continuous gyration is done by assurance picking head mechanism, realizes the continuous harvesting of oil tea.When picking head runs into the tree fork, to pluck silk and push the resilient U-shaped steel wire open certain distance, behind the disengaging tree fork, the elastic force of resilient U-shaped steel wire will be plucked silk and reset, so that continue harvesting.
Compared with prior art; The invention has the beneficial effects as follows: but the avoiding-type of this oil tea fruit picking machine harvesting mechanism is easy to operate; Can realize revolution harvesting continuously, inter-agency coordination is functional, particularly can avoid mechanism stuck by branch; Practical very strong, can be applying of oil tea fruit picking machine technical support is provided.
