Description
Technical field
The present invention relates to a planting fruit-trees harvest machinery, is that a kind of mode of vibration that adopts realizes fruit harvest, the oscillatory type holt fruits harvester that amplitude is adjustable specifically.
Background technology
Constantly accelerate along with traditional industry of planting forest or fruit tress changes paces to modern industry of planting forest or fruit tress, the economic forest of China's industry of planting forest or fruit tress is built and has obtained tremendous development.At present, the kind of domestic economy woods fruit is abundant, can be divided into two kinds of berry and nuts substantially.Compare nut, require more strict to gathering of berry on the gardening.Generally speaking, the berry harvesting needs to keep fruit intact, should avoid fruit damaged to greatest extent, and breakage rate should be controlled at below 10%.Yet some holt fruits (like sea-buckthorn, matrimony vine, Ou Li etc.) are clustered on fruit branch, and adhesion-tight, and the length of carpopodium and the difference in size of adhesive force are very big, make that gathering of fruit is very difficult, and it is main that fruit harvesting is mainly gathered with manual work.But holt really simple grain is heavy less, adopts artificial mode operating efficiency of gathering very limited, has caused the cost of gathering big, and fruit is wasted problems such as serious, has influenced the economic benefit of fruit.Gathering with fructus hippophae is example, plucks the clean fruit of sea-buckthorn and can only receive 5kg-10kg for each person every day by hand, and beta pruning is gathered also only can reach and received 40kg-50kg for each person every day, is difficult to satisfy the raw material supply of relevant enterprise; The artificial beta pruning commonly used pick up rate of gathering is maximum 70%, and is average about 30%, and China will waste fructus hippophae every year more than 500,000 tons like this; Manual picking needs 2.0 yuan/kg of labour cost, and the purchasing price of fructus hippophae is 3.0 yuan/kg, and the cost of gathering accounts for 66.7% of procurement price, has greatly limited the economic worth of sea-buckthorn.This shows that it is very important to the development of holt fruit to develop efficient mechanized harvest technology.
Research in China holt fruits mechanization harvesting technique is started in the end of the eighties, has also obtained some achievements, has developed the multiple manual utensil of plucking.Hand wheel type sea-buckthorn collector like the Maechinery Inst., Shanxi Prov development; The manual sea-buckthorn collector of the 4J-40 type that Heilongjiang Province woods section is developed; The 4S-2 type sea-buckthorn picking device that Shanxi Province's agricultural machinery chemical industry is developed, the manual fruit picking device of toothed plate type of Guyuan of Ningxia area agricultural machinery Research Institute etc.These small hand utensil common features are that operation is nimble, make simply, and are cheap, can improve certain work efficiency with respect to pure manual harvesting, improved the condition of gathering to a certain extent.Make a general survey of several kinds of holt fruits of having developed the utensil of gathering, all be confined to people's Work tool basically, its working head all acts on single operation of sea-buckthorn, adopt scrape, mode such as wiping makes fruit abscission, effect is desirable not to the utmost, is mainly reflected in:
(1) productivity ratio is low, only improves work efficiency 6-8 doubly than manual gathering, and large-area holt is really gathered and needed the raising work efficiency more than 50 times;
(2) the berry pick up rate is low, and it is at most 60% that general manual utensil is gathered holt fruit pick up rate, and the holt fruit tree kind pick up rate tall and big to plant is lower;
(3) the berry serviceability rate is low, and existing manual utensil is prone to pull fruit when gathering, and the berry serviceability rate is 50%-60% only.
In addition; People such as beam Jianping have invented a kind of " air-sucking type holt fruit recovering device " (200810036100.4); Mainly comprise engine, air pump, air-sucking type collecting tank, picking head and relevant machine driven system composition; Picking head comprises mechanical picking working head and suction head, makes that being plucked fruit sucks collecting tank by suction head after mechanical mechanism and branch disengaging.The advantage of this facility is through a cover soaking gas equipment, to change different mechanical picking working heads according to the growth characteristics of the little fruit of difference, is combined into multiple fruit harvesting device, accomplishes the fruit harvesting to different holt fruits.This machine takes off the gentle absorbing sets of fruit with machinery effectively and has carried out integratedly, but the main mode of hitting fruit that still relies on realizes fruit abscission, and work efficiency is still not high.
Summary of the invention
The objective of the invention is to overcome the weak point of prior art, propose a kind of dependence vibration realizing fruit abscission, the efficient of gathering height, and can be through the adjustment amplitude to adapt to the portable facility of gathering that multiple holt is really gathered.
To achieve these goals; The technical scheme that the present invention adopted is: a kind of oscillatory type holt fruits harvester, mainly form by vibration head, extension bar, dirt-proof boot, body, telescopic shaft, connecting rod, air motor, power transmission shaft, bearing, rotary disk, braces, vibration absorbing handle, switch and protection seat.Described air motor is installed in the body outside, links to each other with rotary disk through power transmission shaft; Connecting rod one end and rotary disk are hinged, and the other end and telescopic shaft are hinged; Vibration head links to each other with telescopic shaft through extension bar.
Above-mentioned facility; Gather in order to adapt to the little fruit of variety classes; On said rotary disk, be provided with the screwed hole that a plurality of eccentric throws do not wait and adjust Oscillation Amplitude, the scope that is provided with of eccentric distance e can be adjusted according to the growth characteristics of fruit during work between 20mm-35mm easily.
Above-mentioned facility in order to guarantee stable drive and to use reliably, have been installed pair of bearings and have been supported on said power transmission shaft.
Above-mentioned facility in order to adapt to fruit tree not of uniform size, are provided with small one and large one two " U " type bayonet sockets in said vibration head both sides, lesser calorie mouth width is 30mm-45mm, and big bayonet socket width is 55mm-80mm; Dither damage branch is equipped with the soft rubber pad with protective effect during for fear of work in bayonet socket inside.
Above-mentioned facility, in order to alleviate facility weight, described vibration head, extension bar, body, vibration absorbing handle all adopt the aluminum alloy materials of lightweight.
Above-mentioned facility in order to improve the comfortableness of facility operation, are equipped with vibration absorbing handle on the body, be hinged on the body top through front rod and back link, between front rod and the protection seat damping spring are installed; For the ease of operation, said air motor gauge tap is installed on the vibration absorbing handle.
Above-mentioned facility, in order to carry with easy to use, the body position is equipped with braces, and braces is articulated on the body through 2 of front and back, is available for users to tiltedly carry on the arm.
The invention has the beneficial effects as follows: facility adopt mechanical oscillation to make fruit abscission, can not damage branch, can substitute the little fruit of manual picking effectively, have rapid operation, results efficient advantages of higher; Facility are easy to carry, and amplitude is easy to adjust, and are less demanding to landform and arboreal growth situation, can be used for gathering of the multiple little fruit in different regions, and the scope of application is wider.
