Description
Technical Field
[0001] The utility model relates to the technical field of agricultural machinery, in particular to a fruit picking machine with a light and adjustable amplitude holding clamp. Background Art
[0002] my country is one of the world's largest fruit and vegetable producers, with rich fruit varieties and large production scale. The development of the fruit and vegetable industry has greatly increased the demand for orchard mechanization. Most of my country's orchards are planted in a dwarfing and densely planted pattern, and fruit and vegetable harvesting is still mainly done manually, without targeted harvesting machinery and equipment.
[0003] At present, the main mechanical harvesting methods of forest fruits in my country include pneumatic, combing, impact and vibration. Air-blowing harvesting is a high-speed airflow generated by a high-power fan, which acts on the tree crown under the action of a guide, causing the branches to swing back and forth. When the inertial force of the fruit is greater than the binding force of the fruit stalk, the fruit falls. Air suction harvesting uses the negative pressure generated by the device to adsorb the fruit, and the fruit is separated from the fruit stalk under the action of the airflow generated by the negative pressure. Combing and brushing harvesting, as a typical representative of contact harvesting, uses combing and brushing teeth to comb and brush the branches of fruit trees in rotating, reciprocating, and composite working modes, thereby separating the fruit and branches. In the process of continuous vibration harvesting, continuous vibration will cause continuous collisions between fruits, which is easy to cause bumps and damage to the surface of the fruit; impact harvesting uses a single or a few times of instantaneous high-energy excitation of the fruit tree to cause the fruit to vibrate instantly and separate from the branch under the action of sufficient inertial force. The vibrating harvesting device clamps the tree trunk or branch through a clamping mechanism, and the fruit is forced to move under the action of the vibration generating device. The fruit falls off when the inertial force it is subjected to is greater than the connecting force between the fruit and the branch. Utility Model Content
