Electric manipulator for wolfberry picking

Abstract

The invention discloses an electric mechanical arm for picking wolfberry. The electric mechanical arm comprises a rotary shaft and is characterized in that a plurality of arc plates are fixed on the rotary shaft. A plurality of mechanical fingers is tangentially hinged to the other end of each arc plate, and the mechanical fingers are mounted opposite to a thumb root pulp hinged to the rotary shaft. One end of the rotary shaft is connected with a motor. Each mechanical finger and each thumb root pulp have three, two or one phalanges which are connected through hinges, a pressing spring penetrating from the finger tip to the finger root is disposed in each finger pulp, a thin rope is disposed in each pressing spring, one end of the thin rope is tied to the tail phalange of the corresponding mechanical finger, the other end of the thin rope is tied to the same roller, elastic rubber wraps each mechanical finger, each finger pulp is filled with soft materials, and an arc elastic strip is fixed on the outer side of each finger tip. When the electric mechanical arm is used for picking the wolfberry, green fruits small in size and leaves are allowed to pass among fingers, the mechanical fingers and the thumb root pulps spread when the mechanical arm moves downwardly, and the wolfberry falls among the mechanical fingers into a hose. By the mechanical arm, continuous wolfberry picking is achieved, and the picking speed of the mechanical arm is evidently higher than that of manual picking.

Description

technical field [0001] The invention relates to an electric manipulator, in particular to an electric manipulator used for wolfberry picking. Background technique [0002] Lycium barbarum is generally picked manually. In recent years, some wolfberry picking devices have also been developed, but the picking effect is not ideal: the world's first wolfberry picking machine prototype was born in South Korea. It belongs to extensive picking, and the development of wolfberry picking machine is positioned on a large-scale, fully automatic picking machine, which is in the state of a concept machine. The advantage of this machine is that the picking area is large, and the disadvantage is that it is inconvenient to travel in the field. In 2006, someone in China used the bionic principle to develop a simple wolfberry fruit picker. This machine uses the direct contact between the fruit picking head and the fruit, and is relatively accurate in terms of picking classification. Because ...
