  • Publication number: 20240349648
    Abstract: Disclosed is a portable telescopic push-pull vibrating-shaking type Camellia oleifera fruit picking and beating machine. The machine includes a picking and beating head, a gear shifting mechanism, a power transmission and picking and beating rod, a direct current motor, a control system, a handheld grip, and a lithium battery. A battery supplies power to enable the direct current motor to rotate, the direct current motor drives a worm and worm wheel mechanism in the gear shifting mechanism to rotate through a power transmission rod, the worm and worm wheel mechanism drives the picking and beating head to achieve reciprocating push-pull motion, such that the picking and beating rod can pull a branch to generate push-pull and vibration to pick Camellia oleifera fruit down. The picking and beating head is provided with a force sensor capable of monitoring picking and beating strength at any time.
