Balanced mechanical arm suitable for fruit picking

Abstract

The invention discloses a balanced mechanical arm suitable for fruit picking. The balance mechanical arm comprises a telescopic mechanical arm and a self-balancing telescopic mechanism; the telescopicmechanical arm comprises a telescopic arm, a transmission connecting rod group, a crank, an eccentric wheel connecting rod and a first motor; the transmission connecting rod group is slidably connected to the telescopic arm; one end of the transmission connecting rod group is connected with a manipulator for grabbing branches; the other end of the transmission connecting rod group is connected with one end of the eccentric wheel connecting rod; the other end of the eccentric wheel connecting rod is fixed with a connecting rod pin; a mounting hole for mounting the connecting rod pin is formedon the crank; the first motor drives the crank to rotate so as to drive the transmission connecting rod group to move in a reciprocating mode; the self-balancing telescopic mechanism comprises a telescopic arm sleeve, a double-rotating-direction different-lead screw rod, a mechanical arm balance weight, a second motor and a telescopic force guide rod; and the telescopic arm slides relative to thetelescopic arm sleeve. According to the balanced mechanical arm suitable for fruit picking, self balancing can be realized when the arm length is adjusted, and the balanced mechanical arm does not topple easily when the mechanical arm is extended.

Description

technical field [0001] The invention relates to a balanced mechanical arm suitable for fruit picking. Background technique [0002] The traditional manual picking method is inefficient and cannot achieve the best picking effect in a short period of time, and it is particularly difficult to pick densely packed fruits such as cherries and dates on trees with different heights. [0003] The traditional equipment for picking this kind of fruit is large-scale hydraulic picking equipment. However, due to the strong power of this kind of picking equipment, it will cause damage to the tree itself to a certain extent, and the price is high. [0004] The traditional small telescopic manipulator cannot achieve self-balancing, and it is easy to fall over after the manipulator is extended. Contents of the invention [0005] In order to solve the deficiencies of the prior art, the invention provides a balanced mechanical arm suitable for fruit picking that is not prone to tipping when ...
