Description

A kind of adaptive tree crown vibrating device for fruit harvest
Technical field
The utility model belongs to orchard harvesting field of mechanical technique, and in particular to a kind of adaptive tree for fruit harvest It is preced with vibrating device.
Background technology
At this stage, China's agriculture, the harvest of forestry fruit are substantially still harvested by manpower, but fruit harvesting Labor intensity is big and seasonal strong, inevitably result in labor cost increase, particularly Chinese chestnut, walnut, English walnut, jujube, The economy class such as matrimony vine crop and the harvest for making juice fruit, therefore the mechanized harvesting of fruit is to improve harvesting effect Rate and the key for reducing operating cost.With the continuous development of Agricultural Machinery Technology, oscillatory type harvesting is used as fruit scale The effective ways of harvest have carried out widely studied and have achieved some achievements by domestic and foreign scholars.Tree crown vibrates and trunk shakes Act for oscillatory type harvesting two kinds of principal vibration modes, tree crown vibration relative to trunk vibration in recovery process can not between Disconnected operation, therefore tree crown is vibrated in high efficiency large-scale production advantageously.
On trunk oscillatory type recovering device, Chinese patent CN200820125040.9 describes a kind of vibrating type fruit tree and adopts Receipts machine, is made of shaking device, hydraulic control system, fuel tank and counterweight, and tractor motive power output shaft PTO passing powers are to jaw type Vibration head, then trunk is clamped by jaw type vibration head, drive the eccentric wheel swing mechanism built in vibration head to push away and shake fruit tree, fruit is shaken Fall.The equipment operation is simple, and harvesting speed is fast, saves labour, but complicated, manufacture cost is higher, can not realize to compared with The vibration harvesting of big fruit tree.Chinese patent CN201410577353.8 proposes a kind of self-propelled mechanical reciprocating complex peach harvest Machine, is made of power take-off mechanism, supporting powered lift mechanism, reciprocating movement converting device, guider and clamping device, should The complex Peach fruits that cropper can be completed disposably below single plant diameter of a cross-section of a tree trunk 1.3 meters above the ground 320mm in 20 seconds come off, and harvest efficiency is higher but machine Tool configuration flexibility is poor, and whens recovery operations needs that trunk is fixed with clamping device, so that the harvesting of this discontinuity is by pole It is big to influence fruit harvesting efficiency.Chinese patent CN201410349314.2 has invented a kind of self-propelled vibration woods fruit harvesting and its has adopted Receiving method, including walking chassis, picking mechanical arm and vibration picking head, the picking mechanical arm in the device turn round on base Movement, vibration picking head do the swing of certain angle to meet that need are picked in the vibration to fruit by pivoted link mechanism around column Ask, but the mechanical arm type structure of the device is excessively complicated, also needs to position picking head in recovery process, to a certain extent It also limit the raising of harvest efficiency.United States Patent (USP) US5595054A(1997)Describe a kind of mechanical-vibration type fruit harvester (Mechanical tree shaker for fruit harvesting), including vibrator, adjustable spring, guidance system with And clamping device etc., the vibrator of the device are connected by guidance system with clamping device, are installed on adjustable on guidance system Spring is deformed under vibrator effect so that resonance is produced when gripping apparatus grips trunk or branch, with realization to fruit Vibrate the purpose of harvesting.
Above patent has been highlighted carries out fruit tree vibration harvesting, domestic and international researcher couple using trunk mode of vibration Tree crown vibration harvesting have also been made numerous studies, especially carry out mechanized harvesting to fruitlets such as citrus, olive, matrimony vines.China Patent CN201621365984.4 discloses a kind of medlar-picking machine vibrating picker, and the device is using driving lever row's opposite direction The technology of vibration eliminates branch of bearing fruit and avoids the situation of vibrating arm to improve harvest efficiency, and all driving levers in vertical direction Damage of the exciting force to branch can be reduced around vertical shaft passive rotation.United States Patent (USP) US4860529(1989)Describe one kind Mechanical vibrator for fruit harvest(Shaking mechanism for fruit harvesting), including rack, Rocking arm, eccentric mechanism, nail tooth drum, ratchet mechanism and radially-arranged flexible link etc., during recovery operations, flexible link is in bias Take turns lower produce of mechanism effect to vibrate, tree crown is impacted after vibrating arm is inserted into tree crown to realize fruit abscission, the device for mechanical structure Simply, good reliability.European patent EP 2617279A1(2012)Disclose a kind of continuity fruit harvest equipment(Fruit harvesting equipment), which is made of vibrating device, collection device, transmission device etc., vibrating arm radial arrangement In being connected on vibration column into spindle shape, vibration column with the vibrating mechanism of hydraulic-driven, during recovery operations, shaking on vibration column Lever insertion tree crown realizes vibration to tree crown under the driving of vibrating mechanism, at the same vibrating arm be inserted into the angle of tree crown can be with Shape of tree-crown changes, which effectively can carry out continuous shaking harvesting to dense fruit shrubs, especially suitable Harvest for olive.It can thus be seen that the vibration of continuity tree crown is improving fruit harvesting relative to the vibration of discontinuity trunk It is with the obvious advantage in efficiency.
Tree crown damage of the vibration to fruit tree at present and the influence for carrying out annual crops are to restrict oscillatory type harvesting large-scale development With the main bugbear of application, the bottleneck that Gonna breakthrough, vibrating arm must be just improved to the adaptability of tree crown to reduce to tree The damage of hat.Therefore, a kind of adaptive tree crown vibrating device of necessary exploitation is most in the case where keeping higher harvest efficiency It may be decreased the damage to fruit tree.
The content of the invention
The purpose of this utility model be in order to solve the tree crown vibrational system currently used for fruit harvest there are function it is single, The problem of fruit tree damage is larger, there is provided a kind of adaptive tree crown vibrating device for fruit harvesting, used vibrating arm It is made by bow-shaped structural and using flexible nylon material, is produced when impacting tree crown as different stress produce different distortion with tree crown Raw adaptive vibration, mitigates the damage to tree crown to a certain extent.Designed vibrating device front two rows vibrating arm interlocks cloth Office, adds the distance between vibrating arm, the passability of branch in tree crown vibration recovery process is improved, so as to reduce to fruit The damage of tree.In addition, front and rear two rocking bar of designed linkage crank and rocker mechanism drives overhanging vibrating arm to do differential fortune It is dynamic, so as to keep compared with high vibration efficiency to improve recovery ratio.The tree crown vibrating device can be adjusted according to different top fruit sprayer sizes With the harvesting suitable for a variety of fruits, versatility and adaptability are preferable for structure and operating parameter, and with operation flexibly, can tie up The features such as shield property is good, the scale suitable for fruit harvest.
