Embodiment 1

[0026] see figure 1As shown in the wolfberry picking device, there are two sets of rollers (travelling mechanisms) 2 on both sides of the lower part of the frame 1, and the air compressor and the travelling driving device for driving the rotation of the rollers are respectively arranged on both sides of the frame. There are two sliding rods 3 and 4 on the rack, the upper ends of the two sliding rods are connected, and the two sliding rods form a parabola with an opening downward. A plurality of nozzles 5 are arranged on the nozzle holder 6, each nozzle communicates with the air passage on the nozzle holder, and the air passages on the two nozzle holders respectively communicate with the air outlet of the air compressor through the ejection pipeline. A solenoid valve is provided on each of the two ejection pipelines. The nozzle holder can slide along the sliding rod, while the nozzle can swing relative to the nozzle holder. The nozzle holder is provided with a driving device ...

Embodiment 2

[0031] The interval of blowing air to the branches of the wolfberry alternately from both sides is controlled by the solenoid valve, so as to realize the swing of the wolfberry relative to the branches. In the experiment, when the distance between the nozzle and the wolfberry branch is about 350mm, the speed of the airflow reaching the wolfberry branch is about 14m / s. The switching frequency of the two solenoid valves is 3Hz (the time in the open state and the closed state are equal), and the two ejection pipelines blow air alternately. According to the calculation formula of Example 1, the force acting on the mature wolfberry is 1.57×10 -2 N, which is equivalent to the gravity of 1.6g of heavy objects, plus the self-weight of wolfberry exceeds 0.6g, so it can meet the condition of overcoming the binding force (2g) of the fruit stem of mature wolfberry, and the fruit of wolfberry can fall off the branches. In addition, the high-speed airflow can be turned on and off through t...

Embodiment 3

[0033] see image 3 , 4 In the wolfberry picking device shown, the nozzle frame 23 includes two left and right lifting plates 231 and 232; two left sliding rods 241 and one left sliding table guide rod 251 are fixed on the left lifting plate; A right slide bar 242 and a right slide guide bar 252 . The two left sliding rods 241 and the left sliding table guide rod 251 are parallel to each other, and the two right sliding rods 242 and the right sliding table guide rod 252 are parallel to each other. The upper end of the left sliding rod 241 is inclined to the right, and the upper end of the right sliding rod 242 is inclined to the left. The left and right sliders form the two waists of an isosceles trapezoid.

[0034] The upper ends of the two left sliding bars 241 are connected by a left longitudinal bar 261 , and the upper ends of the two right sliding bars 242 are connected by a right longitudinal bar 262 . The left sliding table 271 is slidably arranged on the left slidi...

Abstract

The invention provides a method for picking Chinese wolfberries by high-speed air flow and a Chinese wolfberry picking device. The method is high in picking efficiency, simple and convenient to implement and low in degree of damage to green fruits and flowers. The method for picking the Chinese wolfberries includes utilizing the high-speed air flow to blow the Chinese wolfberries to enable ripe Chinese wolfberry fruits to fall off from branches of wolfberry trees. The Chinese wolfberry picking device comprises a frame, ejection pipelines communicated with a compressed air source and used for ejecting the high-speed air flow are arranged on the frame, sliding rods are arranged on the frame, nozzles which can slide along the corresponding sliding rod and swing relatively to the sliding rod are arranged on each sliding rod, and the each nozzle is communicated with an outlet of the corresponding ejection pipeline.

Description

technical field [0001] The technology relates to a wolfberry picking method and a wolfberry picking device. Background technique [0002] Lycium barbarum is an economic crop that is widely grown in Northwest my country. In the annual ripening season of wolfberry, only one district of Ningxia Hui Autonomous Region employs tens of thousands of foreign workers to pick wolfberry by hand, which is labor-intensive and inefficient. The cost of picking wolfberry reaches 1.3-1.5 yuan / catties. The existing semi-mechanized picking technology of wolfberry (such as technical patent application publication numbers CN101167419, CN101326879) mainly drives the "mountain"-shaped or "comb"-shaped fruit picking head to directly shake the wolfberry fruit tree by driving the crank connecting rod mechanism by the motor. A certain branch makes the mature wolfberry fruit separate from the branch. This method requires the workers to cooperate with both hands, turn around the wolfberry tree about 1....
