High-speed airflow jet and screening based red date picking device and use method

Abstract

The invention discloses a high-speed airflow jet and screening based red date picking device and a use method. The high-speed airflow and screening based red date picking device includes a jet device,a lifting device, a guiding device, a vibration screening device, a power device, and a conveying device; the jet device includes an air gun; the air gun is arranged on a lifting rod and fixed by anadapter; the air gun is connected to an air compressor through a hose; the power device is an air compressor driven by a diesel. The advantages of the invention are that compared with other large-sizepicking machines, the high-speed airflow jet and screening based red date picking device is flexible and changeable to operate, is selective in picking, will not damage date trees, is low in cost, and is energy-saving and environment-friendly. The picking device can pick red dates by fully using airflow, can improve the picking efficiency, can reduce the picking manual cost, and can significantlyimprove the picking speed in comparison with the picking speed of manual picking.

Description

technical field [0001] The invention relates to the field of machinery, in particular to an environment-friendly picking device for agricultural products. Background technique [0002] Jujube, also known as jujube, has been listed as one of the "five fruits" since ancient times and has a long history. The prominent feature of jujube is its high vitamin content, which has the reputation of "natural vitamin pill". Jujube is rich in vitamins A, B, C and other essential vitamins and 18 kinds of amino acids and minerals, among which the content of vitamin C (ascorbic acid) is 70-80 times that of grapes and apples, rutin (vitamin P) The content of vitamin C is also very high, and these two vitamins have a certain effect on preventing cancer and preventing high blood pressure and high blood lipids. At the same time, other nutritional values ​​of jujube are also extremely rich. For example, jujube can promote the production of white blood cells, lower serum cholesterol, increase s...

Problems solved by technology

Patent 201410078009.4 discloses an air-suction comb-type winter jujube cleaning and harvesting machine. This device uses the comb to rotate the winter jujube to knock it down and then collects it. However, the degree of freedom of the comb is less, and the picking height cannot be changed, and it cannot be raised or lowered. , it is more troublesome to pick some taller fruits

Patent 201310569638.2 discloses a remote-controlled self-propelled winter jujube manual assisted harvesting machine. The device is very simple. It adopts a rotating rod that can be lifted and lowered, and a collection bucket is hung on it, but the fruits that are knocked down by the rotating rod will not all fall into the bucket. The collection work caused certain trouble

201410452634.0 announced a jujube combine harvester, which adopts the method of shaking the branches of the jujube with a lifting and lowering mechanical arm, and then adopts the principle of airflow collection, but in fact it cannot collect the fruit on the ground well

Although the principle has been slightly changed, the actual effect is still poor and cannot be effectively put into production
