Description

Technical Field

[0001] This utility model belongs to the field of fruit harvesting technology, and in particular relates to a harvesting device for *Vernicia fordii* (a type of tung tree). Background Technology

[0002] *Vernicia fordii* is a plant belonging to the genus *Vernicia* in the family Elaeagnaceae. It is widely distributed in China, commonly found in deciduous broad-leaved forests and mixed coniferous and broad-leaved forests on mountain slopes and in valleys at altitudes of 400-2500 meters. *Vernicia fordii* is also known as water melon, oil grape, and chair tree. With its tall stature, broad leaves, and beautiful flowers, it is a plant with high ornamental value. Its fruit is rich in oil, which can be pressed to extract *Vernicia fordii* oil. This oil has wide applications in food, medicine, and industry. The fruit also has heat-clearing and detoxifying properties, and astringent and hemostatic effects, making it effective in treating some heat-related illnesses and bleeding symptoms.

[0003] Existing tung tree fruit harvesting equipment requires first netting the tung tree fruit into a collection bag before cutting the spikelets, which affects harvesting efficiency. Furthermore, if the collection bag opening is too large, it obstructs the view during harvesting, causing the tung tree fruit to fall onto the ground instead of accurately falling into the bag, which then needs to be picked up manually, which is time-consuming and laborious. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a harvesting device for *Vernicia fordii* (a type of vine). When harvesting *Vernicia fordii*, it is not necessary to first put the fruit into a bag with a net. The fruit can be directly cut along the stalk and collected into the bag, which improves the efficiency of harvesting *Vernicia fordii* and solves the problem that *Vernicia fordii* cannot be accurately put into the net bag and falls to the ground because the opening of the collection bag is too large and obstructs the view, requiring repeated collection.

[0005] This utility model solves the above-mentioned technical problems through the following technical means:

[0006] A harvesting device for *Vernicia fordii* includes a telescopic rod. The top of the telescopic rod is equipped with a shearing mechanism, a linkage mechanism, and a fruit-receiving mechanism. The linkage mechanism includes a fixed block, a linkage rod, and a movable block. The fixed block is fixedly mounted on the telescopic rod, and a fixed shaft is fixedly mounted on the fixed block. The linkage rod is rotatably mounted on the fixed shaft. The movable block is slidably mounted on the telescopic rod. A connecting rod is hinged between the lower end of the linkage rod and the movable block. A pull rope is provided on the linkage rod. The shearing mechanism is used to cut the *Vernicia fordii* fruit from the tree. The shearing mechanism includes scissors, scissor handles, a fixing bolt, and a traction rod. The scissor handles are rotatably mounted on the top of the telescopic rod, and a spring is provided between the scissor handles. The fixing bolt is fixedly mounted on the scissor handles. The traction rod passes through the linkage rod and is fixedly mounted on the fixing bolts at both ends. The traction rod connects the linkage mechanism and the shearing mechanism, enabling them to operate in tandem. The scissors are fixedly mounted on the scissor handles, and a pin is provided at the point where the scissors cross. The fruit-receiving mechanism includes a support block and a sliding rod. The support block is fixedly installed on the top of the telescopic rod and below the fixed block. The support block is provided with a sliding groove. One end of the sliding rod is slidably installed in the sliding groove, and the other end is fixedly installed with a fruit-receiving bag. A connecting rod 2 is hinged between the sliding rod and the movable block.

[0007] Based on the above technical solution, the present invention has made the following improvements:

[0008] Furthermore, a fixed pulley is fixedly installed at the end of the linkage rod away from the telescopic rod, and the pull rope is wound around the fixed pulley; this structural design is simple and easy to use, making it convenient for workers to pull the pull rope to trigger the linkage mechanism, thereby driving the linkage of the shearing mechanism and the fruit receiving mechanism.

[0009] Furthermore, the other end of the pull rope is fixed to the telescopic pole; one end of the pull rope is connected to a fixed pulley to facilitate pulling down the linkage rod, while the other end of the pull rope is fixed to the telescopic pole to prevent the pull rope from falling in the opposite direction to the worker's position under the action of gravity when the pole is tilted during use.

[0010] Furthermore, the bottom of the fruit collection bag is equipped with a zipper, which can be opened to quickly empty the fruit from the bag.

[0011] The beneficial effects of this utility model are as follows: the fruit collection bag opens to catch the fruit while the stalk is being cut by the linkage mechanism, eliminating the need to align the fruit with the collection bag before cutting. This also avoids the problem of fruit falling to the ground due to the collection device obstructing the view when cutting the stalk, which leads to repeated collection and is time-consuming and laborious, thus improving harvesting efficiency.

Detailed Implementation

[0018] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments:

[0019] like Figures 1 to 4 As shown,

[0020] A harvesting device for *Vernicia fordii* includes a telescopic rod 1 and a shearing mechanism 2 for cutting the *Vernicia fordii* fruits from the tree. The top of the telescopic rod 1 is equipped with the shearing mechanism 2, a linkage mechanism 3, and a fruit-receiving mechanism 4. The linkage mechanism 3 includes a fixed block 31, a linkage rod 33, and a movable block 35. The fixed block 31 is fixedly mounted on the telescopic rod 1, and a fixed shaft 32 is fixedly mounted on the fixed block 31. The linkage rod 33 is rotatably mounted on the fixed shaft 32. The movable block 35 is slidably mounted on the telescopic rod 1. A connecting rod 34 is hinged between the lower end of the linkage rod 33 and the movable block 35. A pull rope 332 is provided on the linkage rod 33. Pulling the pull rope 332 causes the linkage rod 33 to move downwards away from the telescopic rod 1. The shearing mechanism 2 includes scissors 21, scissor handles 22, fixing bolts 23, and a traction rod 24. The scissor handles 22 are rotatably mounted on the top of the telescopic rod 1. A spring 26 is provided between the scissor handles 22. The fixing bolts 23 are fixedly mounted on the scissor handles 22. The traction rod 24 passes through the linkage rod 33 and is fixedly mounted on the fixing bolts 23 at both ends. The traction rod 24 connects the linkage mechanism 3 and the shearing mechanism 2, enabling their linkage. The scissors 21 are fixedly mounted on the scissor handles 22, and a pin 25 is provided at the intersection of the scissors 21. When the linkage rod 33 moves downwards on the side away from the telescopic rod 1, it tilts upwards on the other side, pulling the traction rod 24 to retract the scissor handles 22 inwards, controlling the opening and closing of the scissors 21 to cut the stalks. The pin 25 facilitates the cutting action of the scissors 21. The fruit-receiving mechanism 4 includes a support block 41 and a sliding rod 42. The support block 41 is fixedly installed on the top of the telescopic rod 1 and below the fixed block 31. The support block 41 is provided with a sliding groove 411. One end of the sliding rod 42 is slidably installed in the sliding groove 411, and the other end is fixedly installed with a fruit-receiving bag 43. A connecting rod 36 is hinged between the sliding rod 42 and the movable block 35. The connecting rod 33 moves downward on the side away from the telescopic rod 1, and the other side tilts upward to pull the traction rod 24 to drive the scissors 21 to cut. At the same time, the connecting rod 34, which is hinged between the connecting rod 33 and the movable block 35, moves the movable block 35, which is slidably sleeved on the telescopic rod 1, upward as the connecting rod 33 tilts upward. When the movable block 35 moves upward, the sliding rod 42 moves linearly in the sliding groove 411, opening the fruit-receiving bag 43 to receive the fruit.

[0021] Specifically, a fixed pulley 331 is fixedly installed at the end of the linkage rod 33 away from the telescopic rod 1, and the pull rope 332 is wound around the fixed pulley 331. This structural design is simple and easy to use, making it convenient for workers to pull the pull rope 332 to trigger the linkage mechanism 3, thereby driving the linkage of the shearing mechanism 2 and the fruit receiving mechanism 4.

[0022] Specifically, the other end of the pull rope 332 is fixed to the telescopic rod 1; one end of the pull rope 332 is connected to the fixed pulley 331 to facilitate pulling down the linkage rod 33, while the other end of the pull rope 332 is fixed to the telescopic rod 1 to prevent the pull rope 332 from falling in the opposite direction to the worker's position under the action of gravity when encountering tilting during use.

[0023] Specifically, the bottom of the fruit receiving bag 43 is equipped with a zipper 431, which can be opened to quickly pour out the fruit from the fruit receiving bag 43.

[0024] The method of using this utility model is as follows: Align the scissors 21 with the ear stalk, pull the pull rope 332, which drives the connecting rod 33 to move downward. As the connecting rod 33 moves, the traction rod 24 drives the scissor handle 22 to retract, the spring 26 is compressed and stores force, and the scissors 21 cuts the ear stalk. At the same time, since one end of the connecting rod 33 is equipped with a fixed pulley 331, it moves downward, and the other end will tilt upward. The connecting rod 34, which is hinged between the connecting rod 33 and the movable block 35, moves upward as the connecting rod 33 tilts upward, causing the movable block 35, which is slidably sleeved on the telescopic rod 1, to move upward. When the movable block 35 moves upward, it drives the connecting rod... The connecting rod 26 moves linearly within the chute 411, and the sliding rod 42, hinged to the connecting rod 26, moves accordingly. The opening of the fruit-collecting bag 43 gradually widens as the sliding rod 42 moves, thus catching the fruit that has been cut off. After the pull rope 332 is released, the spring 26 releases its energy, causing the pull rod 33 to reset, which in turn drives the scissors 21 back to the open state. The fruit-collecting bag 43 returns to its small opening state to avoid obstructing the view. When the fruit-collecting bag 43 has collected a certain amount of fruit, the bottom of the fruit-collecting bag 43 is aligned with the collection box, and the zipper 431 is opened to quickly transfer the fruit, improve harvesting efficiency, and avoid the problem of the tung berries falling to the ground and needing to be collected again.
