Abstract
This patent discloses a kind of vibration output block of forestry picking fruit device, simple and reliable, practical both to regulate, the amplitude that realizes with low cost again regulates.Include housing, main shaft is provided with in housing, on main shaft, slip cap is provided with adjusting sleeve pipe, on main shaft, radial fixing pilot pin is arranged among the helicla flute on adjusting sleeve pipe, adjusting sleeve pipe is fixed with movable eccentric block, and on main shaft, also splined has sleeve, sleeve coaxial sleeve is located at outside adjusting sleeve pipe, sleeve is fixed with fixed eccentric block, and one end of main shaft is that drive end carries out moment of torsion input, and the adjustable side of the other end is coaxially connected with the piston rod of oil cylinder by pressure bearing.When needs adjusting amplitude, push main shaft by oil cylinder and make it axial movement to occur, so the amplitude of equipment also achieves adjustment.
Description
Technical field
The utility model relates to a kind of forestry picking mechanical apparatus for work.
Background technology
China develops fruit harvesting machine from 20 century 70s, and what developed at that time is the mechanical-vibration type fruit picker with walking tractor matching.The method of mechanical harvesting mainly contains jolting method and curries method, and jolting method is machine mining method that should be with the most use.Mechanical-vibration type harvester adopts jolting method, is that foreign applications is maximum, the good type of applicability.China orchard results also to be gathered machinery progressively promoting woods fruit, and its mechanical-vibration type woods fruit harvester is also a kind of method promoted as emphasis.
But what current mechanical-vibration type woods fruit harvester generally adopted is eccentric vibration mechanism.The exciting force of eccentric vibration mechanism is the inertia force being moved in a circle by eccentric block and produce.The most basic element of eccentric vibration mechanism is eccentric block, and by utilizing the centrifugal force of eccentric block that mechanism can be made to produce vibration, layout through the various combination to eccentric block, alteration of form and space structure can develop into different vibrating mechanisms, to meet different conditions of work.Change and various combination according to planform, develop into single eccentric vibration mechanism, symmetrical eccentric vibration mechanism, torsion damping mechanism, chaotic vibration mechanism and planet vibrating mechanism; Pass through practical application, in order to improve the effect of vibration, different amplitudes is adopted required for different fruits, the effect that just can receive, therefore need to need adjusting amplitude for fruit to arrive good effect, but current control method is only simply by the mechanical type adjustment of the position of eccentric adjustment screw and two kinds of regulative modes by PLC electronically controlled motor frequency.The former is reliable with adjustment for these two kinds of regulative modes, but extremely bother, and adjust the gear of amplitude limited, be difficult to the demand meeting various fruit, though the second regulate be a kind of intelligentized step-less adjustment, but reality has again many not using, and cost is too high, user is difficult to accept, and therefore how to design one and has both regulated simple and reliable, practical, amplitude control method with low cost is again a current oscillatory type picking mechanical difficult point in the urgent need to address.
Utility model content
The utility model is intended to the vibration output block providing a kind of forestry picking fruit device, simple and reliable, practical both to regulate, and the amplitude that realizes with low cost again regulates.
The vibration output block of the forestry picking fruit device in this programme, include housing, main shaft is provided with in housing, on main shaft, slip cap is provided with adjusting sleeve pipe, on main shaft, radial fixing pilot pin is arranged among the helicla flute on adjusting sleeve pipe, adjusting sleeve pipe is fixed with movable eccentric block, on main shaft, also splined has sleeve, sleeve coaxial sleeve is located at outside adjusting sleeve pipe, sleeve is fixed with fixed eccentric block, one end of main shaft is that drive end carries out moment of torsion input, and the adjustable side of the other end is coaxially connected with the piston rod of oil cylinder by pressure bearing.
Main shaft rotates under the driving of external motive device, on the one hand drives fixed eccentric block to rotate by sleeve, is rotated on the other hand by pilot pin, adjusting sleeve pipe drive activity eccentric block, the lasting rotation of two eccentric blocks thus realize eccentric vibrating.When needs adjusting amplitude, push main shaft by oil cylinder to make it axial movement occurs, main shaft moves axially and forces adjusting sleeve pipe to rotate, also the rotation of movable eccentric block is namely achieved, because the angle between fixed eccentric block and movable eccentric block there occurs change, so the amplitude of equipment also achieves adjustment.
Further, sleeve is connected in the housing by bearing.To ensure its accuracy of rotating.
Further, the gear that is provided with of its circumference is for engaging with the input gear of outside.Main shaft can not be used as power input part
Further, the both sides of movable eccentric block are respectively provided with a fixed eccentric block.To realize the balance of movement of whole mechanism.
Accompanying drawing explanation
Fig. 1 is the schematic front view of the utility model embodiment.
Embodiment
Below by embodiment, the utility model is described in further detail:
Reference numeral in Figure of description comprises: sleeve 1, gear ring 2, fixed eccentric block 3, main shaft 4, adjusting sleeve pipe 5, pilot pin 6, helicla flute 7, movable eccentric block 8, oil cylinder 9, piston rod 10.
Embodiment is substantially as shown in Figure 1: rotated by two, left and right bearing in the housing and be connected with sleeve 1, the left part periphery of sleeve is provided with gear ring 2, and sleeve is connected with two by pin can the fan-shaped fixed eccentric block 3 of synchronous axial system thereupon.
Main shaft 4 is had by splined at the center of sleeve, between main shaft and sleeve, be also provided with adjusting sleeve pipe 5, adjusting sleeve pipe is slidably socketed on main shaft, and the middle part of main shaft is fixedly welded with a radial pilot pin 6, adjusting sleeve pipe is provided with helicla flute 7, pilot pin being located in helicla flute with gap.Fan-shaped movable eccentric block 8 is also fixedly welded with on adjusting sleeve pipe.
The right of main shaft is provided with an oil cylinder 9 in the housing, gear is connected with for receiving outside power input at the left end of main shaft, the right-hand member of main shaft is coaxially connected with the piston rod 10 of oil cylinder by bidirection press bearing, by controlling in-oil cylinder pressure, the adjustment to main shaft axial displacement can be realized.
This programme also can realize the input of power by sleeve.
Above-described is only embodiment of the present utility model, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this.Should be understood that; for a person skilled in the art, under the prerequisite not departing from the utility model structure, some distortion and improvement can also be made; these also should be considered as protection domain of the present utility model, and these all can not affect effect and the practical applicability of the utility model enforcement.The protection domain that this application claims should be as the criterion with the content of its claim, and the embodiment in specification etc. record the content that may be used for explaining claim.
