Description

Technical Field

[0001] The invention relates to a harvester, in particular to an oil-tea fruit harvester suitable for terraced fields, and belongs to the technical field of forest fruit harvesting machinery. Background Art

[0002] The oil-tea camellia fruit is the fruit of the Camellia genus of the Theaceae family. It is spherical or oval in shape. When ripe, the peel becomes woody and the surface is rough. It contains 1-3 tea seeds. Its seeds are rich in oil (tea oil). It is an important woody oil crop in southern my country. The content of unsaturated fatty acids in tea oil is as high as 90%, and it is known as the "Oriental olive oil". It has health benefits such as lowering blood lipids and anti-oxidation. The oil-tea fruit has a long growth period (about 1 year) and matures around the time of frost. It needs to be picked in time to avoid mildew.

[0003] In the prior art, for example, the invention with application number 202410627789.7 discloses a swing-arm tea fruit harvester. In order to solve the problems that the existing harvester chassis has poor passability and adaptability and cannot adapt to terraced fields or complex terrain operations, the existing self-propelled harvester needs to move every time it harvests a tree, the efficiency is low, the clamping claws cause great damage to the tree body, and the vibration parameters are fixed, the expansion valve group is installed on the main frame through the slewing support, the slewing support is driven by a rotating drive motor to rotate, and the slewing drive motor is used to drive the slewing support to drive the expansion valve group. The expansion valve group rotates, thereby driving the folding arm group on the expansion valve group to rotate. The harvesting head is installed on the folding arm group. Under the condition that the walking chassis does not move, the folding arm group and the slewing support can be adjusted to collect nuts on the trees in front of the vehicle and on the left and right sides. The nuts on the trees can be collected in complex terrains, and the trees located at high places can be operated in terraced environments. In dense forests, the surrounding trees can be operated by rotating the slewing support. There is no need to move every time a tree is harvested, thereby improving the harvesting efficiency.

[0004] Similar to the above application, there are still some shortcomings:

[0005] High-frequency vibration can easily lead to branch breakage and bark peeling, especially on old trees with a high degree of lignification. It will weaken the tree and affect the amount of fruit in the next year. It is also unable to distinguish the degree of maturity and can easily knock down immature green fruits, resulting in a decrease in oil content. At the same time, young fruits that do not meet the harvesting standards may be mistakenly picked. In addition, in mountainous areas or densely planted forests with a slope of more than 25°, equipment is difficult to move and operating channels need to be opened in advance, increasing the cost of forest land transformation.

[0006] For this reason, a tea fruit harvester suitable for terraced fields is designed to optimize the above problems. Summary of the invention

[0043] Overall working principle: when in use, push the mobile cart 1 to move the device to the side of the oil-tea fruit tree, and point the balance board 2 toward the oil-tea fruit tree, insert the anti-skid cone block into the ground to stabilize the position of the device, the anti-skid cone block is made of alloy steel, with a cone angle of 45° and a height of 5cm. There are 6 evenly distributed along the bottom edge of the balance board, and the cone tip is embedded to a depth of ≥3cm. Then hold the picking mechanism 9 and control the telescopic movement of the swing arm 8. Control the telescopic movement of the picking mechanism 9 on a single horizontal plane to perform picking operations. The swing arm adopts 3 sections, and the single section stroke is 50cm. The use of the movable connection mechanism 10 can rotate and adjust the picking mechanism 9 within a small range, making the picking process more flexible. At the same time, during the picking process, the up and down movement of the mounting block 7 can be controlled to change the picking plane. The picked oil-tea fruits enter the collection basket 12 through the discharge pipe 11 under the force of gravity for storage. If the picking When the position of the tea fruit is lower than the horizontal height of the collecting basket 12, the tea fruit cannot directly enter the collecting basket 12 at this time. The auxiliary conveying mechanism 14 is used to blow the tea fruit toward the inside of the collecting basket 12 to avoid blockage in the discharge pipe 11. When the tea fruit is at a higher position, the pickers can stand on the top of the pallet 6 and use the lifting mechanism 4 to control the pallet 6 to rise for high-position picking. The pallet 6 is an aluminum alloy frame, and a non-slip rubber pad is provided on the top of the aluminum alloy frame. The maximum load is 200kg and the size is 1200mm×800mm×50mm. After the picking of a single plant is completed, if the height difference between the upper and lower plants is large, the pallet 6 can be raised first, and then the pallet 6 is moved horizontally to a high position. The pallet 6 is used as a support point, and then the mobile cart 1 is controlled to move up to the plane where the pallet 6 is located, and then the mobile cart 1 is completely pushed horizontally to a high position to complete the transfer of the device.

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

[0045] Partial 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, and then the pushing device moves. After moving to the specified position, the vertical frame 101 is adjusted to a vertical position, and the balance board 2 is in contact with the ground.

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

[0047] Local working principle: When the device is lifted, the hoist 403 is started to wind up the steel wire rope 404, and the sliding plate 3 fits on the outside of the vertical frame 101 and moves vertically upward. When the sliding plate 3 needs to be lowered, the hoist 403 is used to release the steel wire rope 404. The installation position of the storage battery 402 can act as a counterweight to facilitate tilting the vertical frame 101 downward.

[0048] In this embodiment, the picking mechanism 9 includes a housing 901, a rotating motor 903, a shaft rod 904, a C-shaped rod 905, and a handle 907. An opening is provided at the top of the housing 901. The bottom end of the housing 901 is communicated with the discharge pipe 11. A rotating motor 903 is installed on the side of the housing 901. A shaft rod 904 is rotatably installed between the output end of the rotating motor 903 and the inside of the housing 901. A C-shaped rod 905 is fixed to the side of the shaft rod 904. A handle 907 is vertically fixed to the top of the housing 901.

[0049] Local working principle: During the picking process, the rotating motor 903 is always in the starting state to control the rotation of the C-shaped plate 905. Hold the handle 907 with both hands and move the housing 901 towards the position of the oil-tea fruit. After the oil-tea fruit enters the inside of the housing 901 through the opening, the rotation of the C-shaped plate 905 will scrape off the oil-tea fruit, and the oil-tea fruit will fall into the inside of the housing 901 and enter the inside of the collection basket 12 along the discharge pipe 11.

[0050] In this embodiment, sawteeth 902 are evenly provided on the bottom edge of the opening of the housing 901. The distance between the shaft rod 904 and the sawteeth 902 is the same as the width of the C-shaped rod 905. Rubber pressing plates 906 are fixed to the symmetric sides of the shaft rod 904 and the C-shaped rod 905. The width of the rubber pressing plate 906 is the same as the width of the C-shaped rod 905.

[0051] Local working principle: The housing 901 is made of engineering plastic ABS+PC, the serrations 902 are polyurethane-coated metal teeth, the rubber pressing plate 906 has a Shore hardness of 80A. The setting of the serrations 902 can clamp the stalk of the oil-tea fruit, limit the oil-tea fruit, and make it more convenient to scrape off the oil-tea fruit during the rotation of the U-shaped rod 905. After the oil-tea fruit is scraped off, if it does not directly enter the inside of the discharge pipe 11, the rubber pressing plate 906 can push the oil-tea fruit into the inside of the discharge pipe 11.

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

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

[0054] In this embodiment, a vertical guide groove 501 is vertically opened on the inner side of the L-shaped plate 5. A screw rod 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 rod 503 is threadedly connected to the mounting block 7. A lifting motor 502 connected to the end of the screw rod 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] Local working principle: During the process of picking while holding the handle 907, by pressing the control switch 504 with the thumb, the lifting motor 502 can be quickly controlled. The forward and reverse rotation of the lifting motor 502 drives the screw rod 503 to rotate, and the screw rod 503 controls the mounting block 7 to slide inside the vertical guide groove 501, enabling quick adjustment of the picking height and making it more convenient to use.

[0056] In this embodiment, horizontal guide grooves 505 are opened along the length direction at the bottom end of the L-shaped plate 5. Sliders are slidably installed inside the horizontal guide grooves 505, and the sliders are fixedly connected to the side of the bottom of the support plate 6 close to the sliding plate 3.

[0057] Local working principle: During the sliding of the support plate 6, the sliders are used for limiting to prevent the support plate 6 from slipping off.

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

[0059] Partial working principle: After picking is completed, the control cross bar 1302 moves toward the side of the collecting basket 12, and squeezes the spring 1303, and the U-shaped rod 1301 moves toward the inside of the collecting basket 12 to release the discharge pipe 11, and then the discharge pipe 11 is taken out, and the collecting basket 12 is lifted down to pour out the oil tea fruits.

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