[0002] Palm fruit is the mature fruit of the saw palm, also known as the saba palm. It is a shrub belonging to the palm family and usually grows in hot climates. Its mature, dried fruit can be used for medicinal purposes. More importantly, palm fruit contains up to 50% oil, and the average yield of oil per hectare during economic cultivation is about 1 ton. It is the world's second largest source of edible vegetable oil and has great economic value.

[0003] Currently, the trunks of common palm trees are typically 3-10 meters high, with a maximum height of about 15 meters. The palm fruits are mostly found in clusters at the crown. Therefore, existing technology for harvesting palm fruits mainly involves workers using shovels to cut them off from the trunk from bottom to top. This is not only labor-intensive but also poses a significant safety hazard to workers below the tree. Therefore, in response to the problems of existing technology, the applicant will provide a palm fruit harvesting machine to solve these issues. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1 and Figure 5A palm fruit harvesting machine includes a tracked vehicle body 1. A scissor-type hydraulic lifting platform 2 is mounted on the top of the tracked vehicle body 1, and a harvesting frame 3 is driven onto the top of the scissor-type hydraulic lifting platform 2. A semi-open ring rod 4 is fixed to the top of the harvesting frame 3, and a clamping seat assembly 5 is fitted on the outer side of the semi-open ring rod 4. A transition support assembly 6, a T-shaped guide cylinder 9, a composite transmission rod 7, and a handle 8 are arranged on the top of the clamping seat assembly 5. A main controller and an electrical cabinet are installed on the inner wall of the harvesting frame 3. The main controller is electrically connected to a switch fixed on the top surface of the handle 8 via wires. The transition support assembly 6 is installed between the bottom of the T-shaped guide cylinder 9 and the top of the clamping seat assembly 5. The composite transmission rod 7 is engaged inside the T-shaped guide cylinder 9 and can be adjusted for displacement inside the T-shaped guide cylinder 9. One end of the composite transmission rod 7 is drivenly connected to the handle 8, and a shovel 10 is mounted on the other end of the composite transmission rod 7.

[0025] When in use, the worker first enters the interior of the picking frame 3, opens the tracked vehicle 1, and the tracked vehicle 1 drives the picking frame 3, the worker and other equipment to move automatically in the plantation until they stop at a suitable position next to the palm tree to be picked. Then, the scissor-type hydraulic lifting platform 2 is opened, and the scissor-type hydraulic lifting platform 2 automatically raises the picking frame 3 and the worker to a suitable height.

[0026] The specific harvesting process is as follows:

[0027] The worker grips handle 8 and applies force towards the assembly formed by the composite transmission rod 7 and the shovel 10. This causes the sharp cutting surface of the shovel 10 to cut the root of the clustered palm fruit in a parallel or top-down manner, separating it from the trunk and allowing it to fall to the ground under gravity. During the movement of the composite transmission rod 7, the T-shaped guide cylinder 9 provides guidance and support for its movement, providing the necessary force for the worker's subsequent repetitive and frequent operations, and maintaining an efficient working state.

[0028] Please see Figure 7 The clamping seat assembly 5 consists of two upper and lower opposing arc-shaped clamping plates, and both arc-shaped clamping plates can be clamped onto the surface of the semi-open ring rod 4 and connected to each other. The side mechanisms of the two arc-shaped clamping plates are provided with clearance holes, and a first bolt is fitted in the two upper and lower opposing clearance holes. One end of the first bolt is externally threaded with a first nut.

[0029] In use, considering the need for convenient maintenance after damage to the composite transmission rod 7, the blade 10, etc., the clamping seat assembly 5 is set as a composite structure that can be reciprocally separated or assembled with the semi-open ring rod 4. In the event of damage to any of the composite transmission rod 7, the blade 10, etc., the composite transmission rod 7, the blade 10, etc. can be automatically replaced by disassembling the clamping seat assembly 5.

[0030] Please see Figure 7 The transition support assembly 6 includes a semi-open spherical shell 61 and an adjusting ball 62. The bottom of the semi-open spherical shell 61 is fixed to the top surface of a clamping seat assembly 5. The adjusting ball 62 is snapped into the interior of the semi-open spherical shell 61. The top of the adjusting ball 62 is aligned with the bottom of the T-shaped guide cylinder 9, allowing the T-shaped guide cylinder 9 to rotate and adjust along with itself. The front and rear surfaces of the semi-open spherical shell 61 are both fixed with internally threaded sleeve blocks 63. The internal threads of the internally threaded sleeve blocks 63 are connected to positioning bolts 64 that can penetrate the semi-open spherical shell 61 and press and limit the adjusting ball 62.

[0031] In use, considering the need for adjustment of different angles during the top cutting process of the composite transmission rod 7 and the blade 10, the transition support component 6 is used to meet this need, as detailed below:

[0032] First, tighten the positioning bolt 64 to temporarily move the positioning bolt 64 away from the adjusting ball 62, thereby releasing the pressure limit on the adjusting ball 62. Then, with the support of the combination formed by the T-shaped guide cylinder 9 and the adjusting ball 62, the gripping handle 8 can drive the composite transmission rod 7 and the blade 10 to rotate and adjust the angle. The adjusting ball 62 is engaged and positioned inside the semi-open spherical shell 61.

[0033] During periods when the entire device is not in use, in order to reduce the footprint, the composite transmission rod 7 is rotated until it is parallel to the semi-open ring rod 4 at its bottom, and the two positioning bolts 64 are then reset and locked.

[0034] Please see Figure 5 An assembly slot is provided on one side of the picking frame platform 3. A protective frame door 11 is installed in the assembly slot by means of a pin hinge. A cabinet door lock is installed at the rear end of the protective frame door 11. A locking sleeve fixed to the inner wall of the picking frame platform 3 is fitted onto the output end of the cabinet door lock.

[0035] In use, considering the flexibility of workers entering and exiting the picking platform 3, a protective frame door 11 is installed and hinged to the picking platform 3. When a worker needs to enter the picking platform 3, the protective frame door 11 rotates to make way. After the worker enters the picking platform 3, the protective frame door 11 is reset and closed, thus restoring the complete protective effect of the picking platform 3 on the worker.

[0036] Please see Figures 1-7 The composite transmission rod 7 includes a hollow shaft 71 and an electric push rod 72. The electric push rod 72 is fitted inside the other end of the hollow shaft 71. One end of the hollow shaft 71 passes through the T-shaped guide cylinder 9 and is connected to the front end of the handle 8. The output end of the electric push rod 72 passes through the other end of the hollow shaft 71 and is connected to the rear end of the blade 10. The rear end structure of the blade 10 and the other end of the hollow shaft 71 are both fixed with flanges, and the two flanges are fitted with a second bolt. One end of the second bolt is externally threaded with a second nut.

[0037] In use, considering the further need for automated harvesting, the electric push rod 72 is used as an auxiliary power source for the shovel 10. The specific operation is as follows:

[0038] After finding the right position for the top cut, first push the composite transmission rod 7 as a whole until the cutting surface of the shovel 10 presses against the root surface of the palm fruit. Then, start the electric push rod 72, and the output end of the electric push rod 72 drives the shovel 10 to automatically cut the root of the palm fruit, thereby achieving the effect of automatic harvesting, reducing the labor intensity of workers and improving harvesting efficiency.
