Description

Technical Field

[0001] This utility model relates to an olive fruit harvesting machine, belonging to the field of agricultural machinery technology. Background Technology

[0002] Olive harvesting relies primarily on manual labor, which suffers from low efficiency, high risks associated with working at heights, and high labor intensity. Existing technologies using mechanical oscillating and beating methods for harvesting have been applied, but they generally suffer from the following drawbacks: 1) Insufficient adaptability of the mechanical structure to tree canopies of varying heights; 2) Excessive vibration during operation, easily leading to operator arm fatigue; 3) A single oscillation frequency, unable to adjust the vibration intensity according to the ripeness difference between green and ripe olives, easily resulting in low harvesting efficiency or fruit damage; 4) Bulky equipment, poor ergonomics, and high operator workload. Therefore, there is an urgent need for a dedicated harvesting device that is efficient, low-vibration, adjustable, and comfortable to operate. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide an olive fruit harvesting machine with low vibration, high picking efficiency, adjustable height, and comfortable operation.

[0004] This utility model is achieved through the following solution: an olive fruit harvesting machine, comprising: The harvesting unit is connected to the handheld unit via a telescopic tube assembly. The harvesting unit includes a housing, a motor housed within the housing, a gear transmission assembly driven by the motor, and left and right swing arms symmetrically arranged on both sides of the housing. Each of the left and right swing arms has a harvesting stick at its front end. The gear transmission assembly has two symmetrical, oppositely rotating output ends, each connected to the left and right swing arms via a connecting rod assembly. The handheld unit includes a handle housing, a main control board and a battery pack housed within the handle housing, and a display screen, control switch, and starter trigger on the surface of the handle housing. The telescopic tube assembly includes an outer tube and an inner tube fitted inside the outer tube. The upper end of the inner tube connects to the housing of the harvesting unit, and the lower end of the outer tube connects to the handle housing of the handheld unit. A locking sleeve is provided at the connection between the outer and inner tubes. The main control board is electrically connected to the motor via a wire passing through the telescopic tube assembly.

[0005] The gear transmission assembly includes a gearbox body and gears 1, 2, 3, 4 and 5 disposed therein; the output shaft of the motor is connected to gear 1, gear 1 meshes with gear 2, gear 2 meshes with gear 3, gear 3 meshes with gears 4 and 5 simultaneously, and the axes of gears 4 and 5 (136) are on the same straight line and are arranged symmetrically.

[0006] The handle housing of the handheld part is composed of a left shell and a right shell joined together; the display screen, control switch and start trigger are all arranged on the right shell.

[0007] The harvesting unit's casing is composed of an upper shell and a lower shell joined together.

[0008] A motor cover that covers the upper part of the motor is fixedly connected to the upper shell.

[0009] The picking stick is mounted on the front end of the left and right swing arms via a detachable bracket.

[0010] A sponge sleeve is fitted into the middle of the outer tube.

[0011] The beneficial effects of this utility model are as follows: 1. The left and right swing arms are driven by the symmetrical and counter-rotating gears four and five in the gear transmission assembly, which can effectively counteract most of the inertial force generated during operation, significantly reduce the vibration transmitted to the operator's arm, and alleviate fatigue. 2. By adjusting the motor speed or working mode through the main control board, the swing frequency and amplitude of the swing arm can be changed, thereby controlling the beating force to adapt to the picking needs of fruits with different ripeness, improve picking efficiency and reduce energy loss and fruit damage. 3. The telescopic tube assembly, consisting of an inner and outer tube, along with a locking sleeve, allows for flexible adjustment of the machine's working height, easily accommodating tree canopies of varying heights. 4. The integrated control and display handheld design, lightweight materials (such as carbon fiber rods), and the use of sponge sleeves all contribute to improving the comfort and convenience of operating the equipment and reducing the labor intensity of long-term work.

Detailed Implementation

[0017] The following is combined Figure 1-4 The present invention will be further described below, but the scope of protection of the present invention is not limited to the contents described herein.

[0018] Example 1 like Figure 1 and Figure 2 As shown, this utility model provides an olive fruit harvesting machine, which mainly consists of three parts: a harvesting part 1, a telescopic tube assembly 2, and a hand-held part 3.

[0019] The harvesting section 1 is connected to the telescopic tube assembly 2 via the inner tube 22 below it. The outside of the harvesting section 1 is covered by the housing 11, which is composed of an upper shell 111 and a lower shell 112 joined together by screws to form a sealed space to protect the internal mechanism.

[0020] The telescopic tube assembly 2 is the core component for height adjustment, consisting of an outer tube 21 and an inner tube 22 fitted inside it. The upper end of the inner tube 22 is fixedly connected to the bottom of the housing 11 of the harvesting section 1, and the lower end of the outer tube 21 is fixedly connected to the top of the handle housing 31 of the handheld section 3. A locking sleeve 23 is provided at the overlapping part of the outer tube 21 and the inner tube 22. By loosening the locking sleeve 23, the inner tube 22 can be freely pulled to adjust the working height of the entire machine; after adjustment, tightening the locking sleeve 23 will secure the inner and outer tubes, ensuring stability during operation.

[0021] The handheld part 3 is the control and grip center of the entire machine. Its handle housing 31 is formed by the mating of a left handle housing 311 and a right handle housing 312. The right handle housing 312 integrates a control switch 35, a start trigger 36, and a display screen 34. This layout conforms to right-handed operation habits, making it easy to complete all control operations with one hand and observe the machine status in real time.

[0022] The transmission of power and control signals is achieved through wires 4 running through the telescopic tube assembly 2. One end of the wire 4 is connected to the main control board inside the handheld part 3, and the other end is connected to the motor of the picking part 1, providing energy to the entire system and transmitting control commands.

[0023] In this basic embodiment, the operator can adapt to different height requirements through the telescopic tube assembly 2 and conveniently control the machine's start and stop through the handheld part 3.

[0024] Example 2 Based on the basic structure of Example 1, this example further discloses the specific implementation method and ergonomic optimization scheme of its core driving component.

[0025] Combination Figure 3 and Figure 4 As shown, the internal drive mechanism of the harvesting section 1 is as follows: a motor 12 serves as the power source and is fixedly mounted on a base consisting of a lower shell 112 by bolts. The output shaft of the motor is directly connected to a gear transmission assembly 13.

[0026] The gear transmission assembly 13 is the core component for achieving low-vibration, high-efficiency striking action. For example... Figure 4 As shown, it includes a gearbox body 131 and a multi-stage gear system housed therein. The output shaft of the motor 12 is connected to gear one 132, and power is transmitted to gear three 134 via gear two 133. Gear three 134 acts as an intermediate gear, meshing with gear four 135 and gear five 136 simultaneously. The axes of gear four 135 and gear five 136 are designed to be on the same straight line and are arranged symmetrically about the center of the gear transmission assembly 13. This arrangement ensures that they operate at the same speed but in opposite directions.

[0027] The shafts of gears 135 and 136 are hinged to the left swing arm 14 and right swing arm 15 respectively via connecting rod assembly 17. When motor 12 is working, power is ultimately transmitted to this pair of symmetrical output gears, driving the left and right swing arms 14 and 15 to perform symmetrical reciprocating motion along their rotation axes. To perform the slapping action, lightweight and high-strength carbon fiber picking sticks 16 are mounted on the front ends of the left and right swing arms 14 and 15 via detachable brackets 161.

[0028] In terms of ergonomic optimization, this embodiment features a sponge sleeve 24 fitted around the middle of the outer tube 21. This design effectively increases friction when the operator supports the device, preventing slippage, while also absorbing some vibrations, significantly improving comfort during extended operation.

[0029] In addition, a motor cover 113 is fixed to the upper shell 111 of the picking section 1 by screws. The cover not only protects the motor and prevents foreign objects from entering, but its heat dissipation hole structure also facilitates ventilation and heat dissipation of the motor 12.

[0030] In this advanced embodiment, the inertial forces generated by the left and right swing arms 14 and 15 are largely canceled out by the symmetrically reversed gear transmission system, thereby minimizing the vibration transmitted to the operator's arm. Simultaneously, by adjusting the speed of the motor 12 via the main control board of the handheld unit 3, the striking frequency and force of the swing arms can be steplessly changed, enabling precise and efficient harvesting of olives at different stages of ripeness.

[0031] Although the technical solutions of this utility model have been described and enumerated in detail, it should be understood that modifications to the above embodiments or the adoption of equivalent alternatives are obvious to those skilled in the art. Such modifications or improvements made without departing from the spirit of this utility model are all within the scope of protection claimed by this utility model.
