A flexible vibration mechanism for a berry plant fruit harvesting machine

Abstract

The invention relates to a flexible vibration mechanism of a berry plant fruit harvesting operation machine. It includes a motor (5), a primary gear box (3), a secondary gear box (11), a manipulator vibrating plate assembly (13), a vertical track (8) and a cylinder (9). The secondary gear box (11) is a movable box body, which can slide along the vertical track (8) under the push of the cylinder (9). The manipulator vibrating plate assembly (13) is hooked on the outside of the secondary gear box (11), and can slide up and down together with it. After the motor 5 is decelerated by two-stage gears, the manipulator vibrating plate assembly 13 is pushed through the link mechanism to realize high-frequency small-amplitude vibration. The advantage is that the height position of the vibrating plate assembly 13 of the manipulator can be adjusted according to the height of the plant, and then the fixed-point flexible vibration type harvesting operation is carried out to the berries. High harvesting efficiency and low damage rate.

Description

technical field [0001] The invention relates to a mechanical structure for berry harvesting operation, in particular to a flexible vibration mechanism suitable for a fruit harvesting operation machine for berry plants such as blueberries and wolfberry. It can be adjusted up and down according to the height of the plant, and then the berries can be harvested by a manipulator in a flexible and vibratory manner. Background technique [0002] Fruit harvesting of berry plants such as blueberries and wolfberry is a labor-intensive and labor-intensive work, and mechanized harvesting is imminent. For blueberry harvesting, although according to the needs of labor technology, the most used domestically is hand-held portable blueberry picking equipment, which has the disadvantage of low efficiency and easy damage to blueberry fruit powder. The cam mechanism blueberry picking equipment is the most used in foreign countries, and its machines have the disadvantages of complex structure, ...

AI Technical Summary

Problems solved by technology

Because the chassis and the comb cylinder are huge in size and relatively heavy in weight, the torque that the motor needs to provide must be large. Therefore, the power of the motor that provides the up and down movement of the chassis should also be selected with high power, which greatly increases the cost.

[0006] The second is that the cam mechanism blueberry picking equipment adopts a vibration method that repeatedly vibrates up and down, but the picking method of up and down vibration is easy to damage the plant roots of blueberry trees, and the plant branches will bring greater resistance to the equipment when vibrating up and down. Working for a long time will cause the motor to be overloaded and heat up too quickly, which will easily damage the motor; and repeated vibrations up and down will affect the integrity of the blueberries. The up and down vibrations will provide acceleration for the blueberries when they fall. The probability will cause the berries to be damaged. According to the verification of big data, this equipment will lose about 30% of the yield compared with manual harvesting.
