Description

A kind of unilateral clamping pineapple picker and its application method
Technical field
The invention belongs to agriculture project machinery fields, specifically, the present invention relates to a kind of unilateral clamping pineapple picking dresses It sets and its application method.
Background technique
China is a large agricultural country, and fruit industry is one of main economic source of peasant.The picking of fruit it is not only time-consuming but also It arduously, is always the great difficult problem for perplexing orchard worker.Although orchard workers take various methods in fruit-picking, but do not have It can be well solved the problem of fruit picking difficulty, currently known fruit picking method is mainly that people stands on the ground and directly wins Fruit;Therefore guarantee that fruit timely collecting, reduction harvest operation expense become the important channel for increasing agricultural incomes.
Pineapple fruit has very high nutritive value, and the fiber in pineapple leaf can be used as the weaving material of excellent natural disinfection performance Material, pineapple leaves have extensive pharmacological activity, and medical value is high, since pineapple is perennial fruit, have special structure, In picking process, it need to guarantee that fruit is injury-free, plant is not destroyed, the result situation of second year cannot be influenced, these Part determines that pineapple picking can not achieve extensive mechanization.Currently, China's pineapple cultivation area mainly include Guangdong, Guangxi, The provinces and regions such as Yunnan and Hainan, Softening mostly uses artificial picking form, due on sharp mouth and pericarp sharp in pineapple leaf Prickle be easy to damage picking personnel, seriously affect picking efficiency.There is an urgent need to a kind of pickers by friend peasant To replace artificial directly picking.Therefore, pineapple fruit how is efficiently picked, while reducing the mechanical destruction to plant, is spinach The research emphasis of trailing plants picking fruit.
Existing, pineapple picking mechanical is usually using torsional mode Softening, as recorded in CN201210431101.5 Technical solution.In actual use, when picking using torsional mode, while twisting off pineapple, it be easy to cause pineapple plant The damage of blade and root system.
Another kind is the automatic picking machine of pineapple, it is the place according to pineapple fruit growth all on the center of pineapple tree Portion, neck is longer, will be under fruit using scissors.Picking machine is mounted on the front end of hand tractor carriage, and tractor is forward When walking, the elliptic cutter of picking machine carries out pineapple picking under the driving of power, and picking machine fills four cropping knifes, primary to receive Four row's fruits are cut, when tractor is walked forward, the disc type cutter of picking machine carries out pineapple picking under the driving of power, picking Pineapple afterwards is fallen on the conveyor belt, is transported in the railway carriage of tractor by belt transmission.This machinery have mechanization degree it is high, It is time saving and energy saving, picking efficiency is high, long service life, save a large amount of labours the advantages that.
Equally, although this device for mechanical degree is high, the picking of this single solution for diverse problems is easy to damage fruit, reduces pineapple Economic value;Certain damage more likely is caused to descendants' bud on pineapple plant, influences the result situation of its next year;? Pineapple leaf can be destroyed, influences vein fiber quality therein, but also the growth of plant can be seriously affected, or even cause plant It is withered, and then influence the harvest yield of pinery next year.
