Description

Technical Field

[0001] This invention belongs to the field of agricultural machinery, and in particular relates to a vibrating device for harvesting wolfberries. Background Technology

[0002] Goji berries, an important specialty economic crop in my country, have the growth characteristics of "infinite inflorescences and continuous flowering and fruiting." The fruits have thin skin, tender flesh, and ripen in stages, requiring timely harvesting. Currently, manual harvesting efficiency is only 3-5 kg / h, accounting for over 50% of total production costs, and the increasing shortage of labor severely restricts the industry's development. Existing berry harvesting machinery mostly uses vibration, brushing, pneumatic, or shearing methods, but due to the complex physical and mechanical properties of goji berry branches and significant varietal differences, general-purpose equipment generally suffers from low fruit removal rates, significant damage, and serious misharvesting. Although handheld harvesting devices can improve efficiency by 3-5 times, they still cannot meet the needs of large-scale production; while large self-propelled equipment is limited by unclear vibration fruit removal mechanisms and outdated design theories for key components, and has not yet achieved high-quality continuous harvesting. Therefore, there is an urgent need to develop a high-efficiency, low-damage vibration harvesting device suitable for the characteristics of goji berries. Summary of the Invention

[0003] In view of this, the present invention provides a vibrating device for harvesting wolfberries to solve the above problems.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A vibratory device for harvesting goji berries, mounted on a harvesting support frame, includes: a hydraulic motor, a drive shaft, a pulley assembly, an eccentric block, a connecting assembly, a mounting frame, a vibration assembly, a fixed frame, and a shock absorber.

[0007] Furthermore, the shock absorption device also includes a limiting bracket, the bottom end of which is fixed to the fixed box, the vibration lever passes through the vibration lever, and the limiting bracket is used to limit the vibration lever.

[0008] Furthermore, the connecting assembly includes a connecting rod, a hinge bracket, an outer hinge bushing, and a motor fixing sleeve. One end of the connecting rod is fixedly connected to the vibration lever, and the hinge bracket is installed at the other end of the connecting rod. The outer hinge bushing is hinged to the hinge bracket, the motor fixing sleeve is installed at the top end of the outer hinge bushing, and the mounting bracket is installed at the bottom end of the hinge bracket.

[0009] Furthermore, the pulley assembly includes a main pulley, a secondary pulley, and a belt.

[0012] Furthermore, the aforementioned wolfberry harvesting vibration device is used in pairs.

[0013] The beneficial effects of this invention are as follows: This invention uses a hydraulic motor to drive a transmission shaft, which in turn rotates two eccentric blocks via a pulley assembly.
