Portable walnut picking device

Abstract

The invention relates to a portable walnut picking device. The device comprises a power source with an accelerator control part, a picking rod, a transmission shaft, a vibration mechanism and a picking chuck, wherein the transmission shaft is sleeved in the picking rod; the power source is connected with a lower end of the transmission shaft by a wire flexible shaft; the vibration mechanism comprises a shell and a buffer unit, a push rod, a pinion and an eccentric gearwheel which are all arranged in the shell; the eccentric gearwheel is meshed with the pinion; the buffer unit is connected with an upper end of the transmission shaft and is connected with the pinion by a first shaft; the eccentric gearwheel is connected with the push rod; and the picking chuck is connected with the push rod by a connecting rod. The picking device has the following advantages: the picking device has low cost and small volume, is easy to carry and can efficiently pick the walnuts on the primary branches through vibration.

Description

【Technical field】 [0001] The invention relates to a mechanical picking device, in particular to a portable hickory picking device. 【Background technique】 [0002] Pecan is an important characteristic fruit in mountainous areas of our country. The fruit is rich in nutrition and high in economic value. It is an important economic source for farmers in mountainous areas to get rid of poverty and become prosperous. Timely picking is an important measure to ensure the yield and quality of hickory and reduce tree damage. Because pecans grow on tall trees, it is very difficult to pick them. Traditional characteristic forest fruits are generally picked by hand-picking machines such as high-branch shears. The main contradictions are: poor picking safety, high picking labor intensity, low picking efficiency, and the quality of the fruit may be damaged due to difficulty in timely picking The problem. [0003] Later, some practitioners developed some mechanical picking tools, such as...

Problems solved by technology

However, when it is used for picking fruits such as hickory nuts and Chinese torreya, it is likely to suck the newly grown shoots into the funnel, thereby directly affecting the harvest of the coming year. Therefore, this method is not suitable for hickory and Chinese torreya. In addition, Australia has designed a picking robot, which can use image acquisition technology to distinguish fruits and leaves. By installing the camera on the arm of the robot, the color of the obtained image is compared with the color feature data in the memory. For comparison, if the data match, the fruit will be harvested. If the fruit is blocked by the leaves, the leaves can be blown away with an air jet in order to obtain a clearer picture of the fruit and be harvested. Although the picking robot has high picking efficiency, but Because of its large size, it is not suitable for picking areas with high mountains and steep slopes, and its cost is high, so it is not suitable for widespread use in our country
