Description

Technical Field

[0001] This invention relates to a harvesting machine, and more particularly to a camellia oleifera fruit harvesting machine suitable for terraced fields, belonging to the field of forest and fruit harvesting machinery technology. Background Technology

[0002] Camellia oleifera fruit is the fruit of a plant in the genus Camellia of the family Theaceae. It is spherical or oval in shape, and the pericarp becomes woody and rough when ripe. It contains 1-3 tea seeds, which are rich in oil (tea oil). It is an important woody oil crop in southern my country. The unsaturated fatty acid content of tea oil is as high as 90% or more, and it is known as "Oriental olive oil". It has health benefits such as lowering blood lipids and anti-oxidation. Camellia oleifera fruit has a long growing period (about 1 year) and matures around the time of the first frost. It needs to be harvested in time to avoid mold.

[0003] In the prior art, such as the invention with application number 202410627789.7, a rotary arm type camellia fruit harvester is disclosed. To address the problems of poor maneuverability and adaptability of existing harvester chassis, making them unsuitable for terraced fields or complex terrain, the need to move the machine after harvesting each tree (resulting in low efficiency), significant damage to the tree from the gripping claws, and fixed vibration parameters, this invention utilizes an extended valve assembly mounted on the main frame via a slewing bearing. A rotary drive motor drives the slewing bearing to rotate, and the rotary drive motor is used to drive the extended valve assembly to rotate the machine. The valve assembly rotates, which in turn drives the folding arm assembly located on the expansion valve assembly to rotate. The harvesting head is installed on the folding arm assembly. It can harvest nuts from trees on the front side and left and right sides of the vehicle body by adjusting the folding arm assembly and slewing support without displacement of the chassis. It can harvest nuts from trees in complex terrain, and can operate on trees located at high places in terraced fields. In relatively dense forests, it can operate on surrounding trees by rotating the slewing support, without having to move the vehicle to harvest each tree, thus improving harvesting efficiency.

[0004] The above applications still have shortcomings:

[0005] High-frequency vibration can easily cause branch breakage and bark peeling, especially on old trees with a high degree of lignification. It can weaken the tree and affect the fruit yield the following year. It also makes it impossible to distinguish the maturity level, and can easily knock down unripe green fruits, resulting in a decrease in oil content. At the same time, it may mistakenly pick young fruits that have not reached the harvest standard. In addition, in mountainous areas with a slope greater than 25° or in densely planted forests, it is difficult to move the equipment, and it is necessary to open up the operation channel in advance, which increases the cost of forest land transformation.

[0006] To address these issues, a camellia fruit harvesting machine suitable for terraced fields was designed. Summary of the Invention

[0007] The main objective of this invention is to provide a camellia fruit harvester suitable for terraced fields. The harvesting mechanism, consisting of a casing, saw teeth, a rotary motor, a shaft, a U-shaped rod, a rubber pressure plate, and a handle, is integrated at the front end of a horizontally extendable and vertically lifting swing arm. This is further enhanced by a movable connecting mechanism composed of a spherical groove, ball bearings, and a fixed rod. This allows the device to replace manual harvesting with mechanical harvesting, preventing finger injuries. After harvesting, the fruit can directly enter the collection basket through a discharge pipe, eliminating the need for frequent feeding and increasing the harvesting speed. Furthermore, the individual harvesting method allows for fruit differentiation, ensuring a higher oil yield and preventing damage to the trees, thus enhancing practicality. The mobile cart, composed of a vertical frame, wheels, and a push handle, significantly reduces the device's size compared to vibratory harvesting machines. Smaller and more convenient to move, the device features a lifting mechanism consisting of a mounting plate, battery, electric hoist, wire rope, and guide wheels. This mechanism elevates the harvesters according to the height of the tea trees, allowing for harvesting from higher positions. The lifting assembly, consisting of a vertical guide groove, lifting motor, screw, and control switch located on the vertical side of the L-shaped plate (with the control switch on the handle), facilitates raising the harvesting mechanism. A horizontal guide groove at the bottom of the L-shaped plate connects to a sliding plate, allowing the plate to slide horizontally. In terraced fields with significant elevation differences, the plate can be moved to a higher position first, serving as a support, before the trolley is raised and reset. This makes the device easier to move and more versatile.

[0041] To enable those skilled in the art to more clearly understand the technical solution of the present invention, the present invention will be further described in detail below with reference to embodiments and accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0042] like Figures 1-8 As shown, this embodiment provides a camellia fruit harvester suitable for terraced fields, including a mobile cart 1. A balance plate 2 is horizontally fixed to the bottom of the side of the mobile cart 1. The bottom of the balance plate 2 is provided with anti-slip cones. A slide plate 3 is vertically slidably installed on the side of the mobile cart 1 near the balance plate 2. A lifting mechanism 4 is provided on the mobile cart 1 to control the up and down sliding of the slide plate 3. L-shaped plates 5 are symmetrically installed on the outer side of the slide plate 3. A support plate 6 is horizontally slidably installed between the bottom ends of the two sets of L-shaped plates 5. Mounting blocks 7 are vertically slidably installed on the inner side of each L-shaped plate 5. A swing arm 8 is horizontally rotatably installed on the outer side of the mounting block 7. Multiple sets of swing arms 8 are provided. The ends of adjacent swing arms 8 are horizontally rotatably connected. A picking mechanism 9 is provided at the end of the swing arm 8 at the far end of the outer side of the mounting block 7. A movable connecting mechanism 10 is provided between the picking mechanism 9 and the end of the swing arm 8. A collection basket 12 is provided at the top of the support plate 6 near the slide plate 3. A discharge pipe 11 is provided between the inside of the collection basket 12 and the picking mechanism 9. An auxiliary conveying mechanism 14 is provided at the top of the discharge pipe 11.

[0043] General working principle: In use, push the mobile cart 1 to move the device next to the camellia fruit tree, and position the balance plate 2 towards the tree. Insert the anti-slip cones into the ground to stabilize the device's position. The anti-slip cones are made of alloy steel, with a cone angle of 45° and a height of 5cm. Six cones are evenly distributed along the bottom edge of the balance plate, with the cone tip embedded to a depth of ≥3cm. Then, hold the picking mechanism 9 and control the extension and retraction of the swing arm 8. Control the extension and retraction of the picking mechanism 9 on a single horizontal plane for picking operations. The swing arm has 3 sections, with a single section stroke of 50cm. The use of the movable connecting mechanism 10 allows the picking mechanism 9 to be rotated and adjusted within a small range, making the picking process more flexible. At the same time, the up and down movement of the mounting block 7 can be controlled during the picking process to change the picking plane. The picked camellia fruits, under the influence of gravity, enter the collection basket 12 through the discharge pipe 11 for storage. When the position is lower than the horizontal height of the collection basket 12, the camellia fruit cannot directly enter the collection basket 12. The auxiliary conveying mechanism 14 is used to blow the camellia fruit towards the inside of the collection basket 12 to avoid blockage inside the discharge pipe 11. When the camellia fruit is in a higher position, the harvester can stand on the top of the pallet 6 and use the lifting mechanism 4 to control the pallet 6 to rise for high-level harvesting. The pallet 6 is an aluminum alloy frame with an anti-slip rubber pad on the top of the aluminum alloy frame. It has a maximum load capacity of 200kg and dimensions of 1200mm×800mm×50mm. After a single plant is harvested, if there is a large drop between the upper and lower plants, the pallet 6 can be raised first, and then the pallet 6 can be moved horizontally to a higher position. Using the pallet 6 as a support point, the mobile cart 1 can be moved up to the plane where the pallet 6 is located, and then the mobile cart 1 can be completely pushed horizontally to the higher position, thus completing the transfer of the device.

[0044] In this embodiment, the mobile cart 1 includes a vertical frame 101, wheels 102 and a push handle 103. The vertical frame 101 is vertically arranged, and the wheels 102 are rotatably installed on the side of the vertical frame 101 away from the skateboard 3. The bottom end of the wheels 102 is at the same horizontal plane as the bottom of the balance plate 2, and the push handle 103 is provided at the top of the vertical frame 101.

[0045] Local working principle: When the pushing device moves, hold the push handle 103 to tilt the vertical frame 101 downward, so that only the wheels 102 are in contact with the ground. Then push the device to move. After moving to the designated position, adjust the vertical frame 101 to a vertical position and the balance plate 2 is in contact with the ground.

[0046] In this embodiment, the lifting mechanism 4 includes a mounting plate 401, a battery 402, an electric hoist 403, a wire rope 404, and a guide wheel 405. The mounting plate 401 is horizontally located at the middle position of the side of the vertical frame 101. The battery 402 is provided at the bottom of the mounting plate 401. The electric hoist 403 is installed at the top of the mounting plate 401. The wire rope 404 is symmetrically arranged on the electric hoist 403. The guide wheel 405 is installed at the top of the vertical frame 101. The wire rope 404 passes through the top of the guide wheel 405 and moves down to be fixedly connected to the slide plate 3.

[0047] Local working principle: When the device is raised, the electric hoist 403 is started to wind up the wire rope 404, and the slide plate 3 moves vertically upward against the outside of the vertical frame 101. When it is necessary to lower the slide plate 3, the electric hoist 403 is used to release the wire rope 404. The position of the battery 402 can act as a counterweight to facilitate tilting the vertical frame 101 downward.

[0048] In this embodiment, the harvesting mechanism 9 includes a cover 901, a rotary motor 903, a shaft 904, a C-shaped rod 905, and a handle 907. The top of the cover 901 has an opening, and the bottom of the cover 901 is connected to the discharge pipe 11. The rotary motor 903 is installed on the side of the cover 901. The shaft 904 is rotatably installed between the output end of the rotary motor 903 and the inner side of the cover 901. The C-shaped rod 905 is fixed on the side of the shaft 904, and the handle 907 is vertically fixed on the top of the cover 901.

[0049] Local working principle: During the harvesting process, the rotary motor 903 is always running, controlling the rotation of the shaped plate 905. Hold the handles 907 with both hands and move the cover 901 toward the camellia fruit. After the camellia fruit enters the interior of the cover 901 through the opening, the rotation of the shaped plate 905 will scrape the camellia fruit off. The camellia fruit falls into the interior of the cover 901 and enters the collection basket 12 through the discharge pipe 11.

[0050] In this embodiment, serrations 902 are evenly provided on the bottom edge of the opening of the cover 901. The distance between the shaft 904 and the serrations 902 is the same as the width of the crisscross rod 905. Rubber pressure plates 906 are fixed on the symmetrical sides of the shaft 904 and the crisscross rod 905. The width of the rubber pressure plate 906 is the same as the width of the crisscross rod 905.

[0051] Partial working principle: The cover 901 is made of engineering plastic ABS+PC, the serrations 902 are polyurethane-coated metal teeth, and the rubber pressure plate 906 has a Shore hardness of 80A. The serrations 902 can hold the stem of the camellia fruit and limit its position. During the rotation of the slanted rod 905, it is easier to scrape the camellia fruit off. After the camellia fruit is scraped off, if it does not directly enter the discharge pipe 11, the rubber pressure plate 906 can push the camellia fruit into the discharge pipe 11.

[0052] In this embodiment, the movable connection mechanism 10 includes a spherical groove 1001, a ball 1002, and a fixing rod 1003. The spherical groove 1001 is opened at the end of the swing arm 8. The ball 1002 is rotatably installed inside the spherical groove 1001. The fixing rod 1003 is vertically fixed to the side of the ball 1002, and the end of the fixing rod 1003 is fixedly connected to the cover 901.

[0053] Local working principle: The diameter of the ball 1002 is 25mm, the depth of the spherical groove 1001 is 15mm, the gap between the ball and the groove wall is ≤0.5mm, and a self-lubricating bearing structure is adopted. Since the cover 901 is connected to the ball 1002 through the fixing rod 1003, the cover 901 can be rotated and adjusted at multiple angles during the picking process, making picking more flexible and convenient.

[0054] In this embodiment, a vertical guide groove 501 is vertically provided on the inner side of the L-shaped plate 5. A screw 503 is rotatably installed between the upper and lower ends inside the vertical guide groove 501. The mounting block 7 slides inside the vertical guide groove 501, and the screw 503 is threadedly connected to the mounting block 7. A lifting motor 502 connected to the end of the screw 503 is installed on the top of the L-shaped plate 5, and a control switch 504 is installed on the top of the handle 907.

[0055] Partial working principle: During the harvesting process using the hand handle 907, pressing the control switch 504 with the thumb can quickly control the lifting motor 502. The forward and reverse rotation of the lifting motor 502 drives the screw 503 to rotate. The screw 503 controls the mounting block 7 to slide inside the vertical guide groove 501, which can quickly adjust the harvesting height, making it more convenient to use.

[0056] In this embodiment, the bottom end of the L-shaped plate 5 is provided with a horizontal guide groove 505 along the length direction. A slider is slidably installed inside the horizontal guide groove 505, and the slider is fixedly connected to the bottom of the support plate 6 near the slide plate 3.

[0057] Local working principle: During the sliding process of the pallet 6, the slider is used to limit the movement and prevent the pallet 6 from slipping off.

[0058] In this embodiment, the positioning mechanism 13 includes a U-shaped rod 1301, a crossbar 1302, and a spring 1303. The U-shaped rod 1301 is symmetrically slidably arranged on the side of the collection basket 12. The discharge pipes 11 all pass through the inside of the U-shaped rod 1301. The crossbar 1302 is horizontally arranged on the outside of the collection basket 12. The crossbar 1302 is fixedly connected to the end of the U-shaped rod 1301. The spring 1303 is provided between the crossbar 1302 and the side of the collection basket 12.

[0059] Local working principle: After harvesting, the control bar 1302 moves toward the side of the collection basket 12 and squeezes the spring 1303. The U-shaped bar 1301 moves toward the inside of the collection basket 12, releasing the discharge pipe 11. Then the discharge pipe 11 is taken out, and the collection basket 12 is lifted down to pour out the camellia fruit.

[0060] In this embodiment, the auxiliary conveying mechanism 14 includes an air pump 1401, an air pipe 1402, an annular hollow pipe 1403, and an exhaust port 1404. The air pump 1401 is installed on the top of the pallet 6. The exhaust end of the air pump 1401 is provided with an air pipe 1402. An annular hollow pipe 1403 is provided between the top end of the discharge pipe 11 and the bottom of the cover 901. Exhaust ports 1404 are evenly opened on the inner side of the annular hollow pipe 1403. The exhaust ports 1404 are inclined toward the inside of the discharge pipe 11. The air pipe 1402 is connected to the inside of the annular hollow pipe 1403.

[0061] Local working principle: The air pump 1401 has a working pressure of 0.3MPa, the exhaust port 1404 has a diameter of 3mm and an inclination angle of 30°, and the annular hollow tube 1403 has an inner diameter of 50mm. When the picking position is low, the air pump 1401 is started, and then the gas enters the interior of the annular hollow tube 1403 and is discharged from the exhaust port 1404. This will exert a pushing force on the camellia fruit inside the discharge pipe 11 to facilitate the camellia fruit entering the collection basket 12.

[0062] The above description is merely a further embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope disclosed in the present invention, based on the technical solution and concept of the present invention, shall fall within the scope of protection of the present invention.
