Description

Technical Field

[0001] This invention relates to the field of harvesting equipment technology, specifically a palm fruit harvesting machine. Background Technology

[0002] Palm fruit is rich in various nutrients beneficial to the human body, especially vitamin C. Vitamin C not only has powerful antioxidant capabilities, effectively eliminating free radicals in the body and delaying aging, but also significantly enhances immunity, helping the body fight off infections and diseases.

[0003] In the current technology, palm fruit is mostly harvested manually. However, manual harvesting is not only inefficient but also labor-intensive. Since palm fruit grows quite tall, workers need to climb the trees to harvest it, which is also dangerous. Summary of the Invention

[0008] Furthermore, the number of passive rods is set to four, and the four passive rods are symmetrically arranged around the threaded rod. The end of the return spring away from the driven plate is in contact with the surface of the force cone, and the surface of the moving block is slidably connected to the inner wall of the slide groove.

[0009] Furthermore, the positioning mechanism includes an angle plate, an electric push rod fixedly connected to the surface of the angle plate, a rotating frame fixedly connected to the surface of the angle plate, a hydraulic telescopic rod rotatably connected to the surface of the rotating frame, a fixed plate fixedly connected to the end of the hydraulic telescopic rod away from the rotating frame, a slide rail fixedly connected to the surface of the fixed plate, a moving rod slidably connected to the surface of the slide rail, a buffer rod fixedly connected to the surface of the moving rod, a buffer spring fixedly connected to the surface of the buffer rod, a positioning plate fixedly connected to the end of the buffer rod away from the moving rod, a push column fixedly connected to the surface of the moving rod, a spring plate fixedly connected to the end of the push column away from the moving rod, a driven block fixedly connected to the end of the spring plate, a sliding groove plate slidably connected to the surface of the driven block, and a contact plate fixedly connected to the surface of the driven block.

[0010] Furthermore, the number of positioning plates is set to four, and the four positioning plates are symmetrically arranged around the fixed plate. The end of the buffer spring away from the moving rod is in contact with the surface of the positioning plate. The number of spring pieces is set to two, and the two spring pieces are symmetrically arranged around the positioning plate.

[0011] Furthermore, the cutting mechanism includes a support rod, a slide rod fixedly connected to the surface of the support rod, a force-bearing block slidably connected to the surface of the slide rod, an active rod fixedly connected to the surface of the force-bearing block, an extension rod fixedly connected to the surface of the slide rod, an extension spring fixedly connected to the surface of the extension rod, a passive frame fixedly connected to the surface of the force-bearing block, a push rod rotatably connected to the surface of the passive frame, and a cutting blade fixedly connected to the end of the extension rod away from the slide rod.

The number of support rods is set to four, and the four support rods are symmetrically arranged around the extension rod.

[0013] The present invention has the following beneficial effects: This invention employs a stabilizing mechanism. When the walking track reaches the harvesting position, the motor starts, driving the threaded rod to rotate. As the threaded rod rotates, the rising plate rises, which in turn raises the telescopic rod. Simultaneously, the rising plate moves the driven rod upwards, pulling the moving block closer together. This movement of the moving block also moves the right-angle plate, which in turn compresses the elastic plate. The compression of the elastic plate causes the driven slider to move downwards, pushing the push rod downwards. This push rod, in turn, pushes the driven plate downwards, which in turn pushes the reset rod. The reset rod then pushes the force cone, which, upon contacting the ground, inserts into the soil and pushes the reset rod upwards, causing it to retract. Simultaneously, the upward movement of the force cone moves the push plate, which in turn pushes the stabilizing plate, causing it to expand outwards. This effectively stabilizes the harvester during harvesting and improves harvesting efficiency.

[0014] This invention employs a positioning mechanism. When the threaded rod rotates, it simultaneously drives the angle plate to rotate. When the angle plate reaches a certain position and stops, an electric actuator is activated to push the hydraulic telescopic rod upwards to a certain angle. The hydraulic telescopic rod then extends, simultaneously pushing the fixed plate to extend as well. When the contact plate contacts the fruit tree, it retracts and pushes the driven block to slide on the inner wall of the slide plate. Simultaneously, the driven block slides, causing the spring to move. As the spring moves, it bends, pushing the push column towards a closer direction. The push column then pushes the moving rod towards a closer direction. Simultaneously, the moving rod pushes the buffer rod, which in turn pushes the positioning plate towards a closer direction. This effective positioning mechanism allows for more precise harvesting of palm fruits, preventing them from falling during harvesting.

[0015] This invention, through the setting of a cutting mechanism, enables the moving rod to move in a direction closer to each other while the moving rod moves, causing the force-bearing block to slide in a direction closer to each other on the surface of the sliding rod. Simultaneously, the force-bearing block moves the passive frame, which in turn pushes the thrust rod. The thrust rod, in turn, pushes the extension rod to extend in a direction closer to each other, and the extension rod, in turn, pushes the cutting blade to move. This effectively cuts palm fruit stems of different sizes and automates palm fruit harvesting, saving labor.

[0029] In use, when the walking track 3 moves to the picking position, the motor 4 is started, driving the threaded rod 25 to rotate. When the threaded rod 25 rotates, the rising plate 11 rises, which in turn drives the telescopic rod 12 to rise. As the rising plate 11 rises, it drives the driven rod 13 to move upward. As the driven rod 13 moves, it pulls the moving block 14 to move closer together. As the moving block 14 moves, it drives the right-angle plate 15 to move.

As the force cone 23 pushes upwards, it drives the push plate 24 to move. Simultaneously, the push plate 24 pushes the stabilizing plate 20, causing it to expand outwards. As the threaded rod 25 rotates, it drives the angle plate 31 to rotate. When the angle plate 31 rotates to a certain position and stops, the electric motor is activated. When push rod 32 pushes hydraulic telescopic rod 34 upward and raises it to a certain angle, it activates and extends hydraulic telescopic rod 34. As hydraulic telescopic rod 34 extends, it pushes fixed plate 35 to extend as well. When contact plate 45 contacts the fruit tree, it retracts and pushes driven block 43 to slide on the inner wall of slide plate 44. As driven block 43 slides, it drives spring 42 to move. As spring 42 moves, it bends. As spring 42 bends, it pushes push column 41 to move towards each other. Push column 41 pushes moving rod 37 to move towards each other. When moving rod 37 moves...
