Description
Technical Field
[0001] This utility model relates to a clamping and vibrating walnut harvesting device, belonging to the field of agricultural harvesting technology. Background Technology
[0002] Walnuts, an important woody oilseed crop in my country, are widely cultivated in mountainous provinces such as Yunnan, Xinjiang, and Shaanxi, and have become a significant source of income for farmers in many regions. Currently, manual walnut harvesting mainly employs two methods: tree climbing and long-pole tapping. Tree climbing requires manual ascent of tall walnut trees, posing a serious risk of fall and resulting in low efficiency. Long-pole tapping, using 4-8 meter bamboo or wooden poles to strike branches and shake the fruit down, reduces the risk of working at height, but easily damages buds, affecting next year's yield. In addition, some tools achieve harvesting by vibrating walnut branches, but these also have drawbacks, such as the inability to accurately control the clamping force, the inability to adjust the vibration frequency, and the inability to accurately clamp the target branch due to obstructed vision.

The four protrusions on the outer side of the top telescopic rod housing 10-1 cooperate with the four corresponding grooves on the inner side of the upper telescopic rod housing 10-3.
[0069] The working process of this utility model includes:
[0070] Driven by the motor 13, the spiral rod 10-6 rotates inside the receiving cavity 10-7, thereby driving the middle telescopic rod housing 10-5, the middle spiral rod 10-4, the upper telescopic rod housing 10-3, the upper spiral rod 10-2, and the top telescopic rod housing 10-1 to move in sequence, thus extending the telescopic rod assembly 10 to the height of the walnut branch. At the same time, the display screen 11 displays the observation image of the camera 8 in real time. The propulsion cylinder 9 in the clamping device moves, causing the clamping plate 2 to tighten the branch. Simultaneously, the clamping force changes in real time according to the feedback from the pressure sensor 1. The electric eccentric vibrator 7 starts to operate, causing the branch to sway, thereby achieving the purpose of walnut harvesting.
[0071] Specifically, a clamping and vibrating walnut harvesting device includes a clamping device, a telescopic rod assembly 10, a pressure sensor 1, an electric eccentric vibrator 7, a camera 8, a display screen 11, and a motor 13.
[0072] The telescopic rod assembly 10 consists of several parts. When the equipment is in operation, the worker holds handle 12, and motor 13 starts operating, driving the screw rod 10-6 to rotate. The screw rod 10-6, through its helical engagement, causes the middle telescopic rod housing 10-5 to move upwards. Simultaneously, because the screw rod 10-6 and the middle screw rod 10-4 have grooved and protruding structures for limiting movement, the screw rod 10-6 and the middle screw rod 10-4 rotate synchronously. The rotation of the middle screw rod 10-4, in turn, through its helical engagement, causes the upper telescopic rod housing 10-3 to move upwards. Again, because the middle screw rod 10-4 and the upper screw rod 10-2 have grooved and protruding structures for limiting movement, the middle screw rod 10-4 and the upper screw rod 10-3 rotate synchronously. -2 also rotates synchronously. In summary, the three spiral rods 10-6, 10-4, and 10-2 rotate synchronously. The upper spiral rod 10-2, in turn, uses a spiral engagement to move the top telescopic rod housing 10-1 upwards. Furthermore, the storage cavity 10-7, the middle telescopic rod housing 10-5, the upper telescopic rod housing 10-3, and the top telescopic rod housing 10-1 also have groove and protrusion structures for limiting their movement. Since the storage cavity is fixed, the storage cavity 10-7, the middle telescopic rod housing 10-5, the upper telescopic rod housing 10-3, and the top telescopic rod housing 10-1 do not rotate relative to each other; they only move up and down relative to each other, thus achieving the limiting purpose.
[0073] The display screen 11 will display the images captured by the camera 8 in real time, which will help to accurately locate the position of the target walnut tree branch.
[0074] In the clamping device, the electric eccentric vibrator 7 and the camera 8 are both connected and fixed to the outside of the push cylinder 9. When the telescopic rod reaches the target length, the push cylinder 9 starts to operate. When the push rod 6 is above, the clamping plate 2 is in the open state; when the push rod 6 is below, the clamping plate 2 is in the closed state. At this time, the push rod 6 moves from top to bottom, driving the push plate 3 to move downward as well. The push plate 3 and the clamping plate bracket 4 are connected by a sliding groove, and the clamping plate bracket 4 and the clamping plate 2 are fixedly connected by bolts. The downward movement of the push plate 3 drives the clamping plate bracket 4 and the clamping plate 2 to move from both sides to the middle, thereby gradually closing the clamping plate 2 to clamp the walnut branch. After the clamping plate 2 contacts the walnut branch, the pressure sensor 1 is activated and feedback is sent to the push cylinder 9. The push cylinder 9 controls the push rod 6 reasonably according to the feedback to achieve a suitable clamping force on the walnut branch and avoid damage to the walnut branch.
[0075] The clamping device allows for free adjustment of the clamping force via a pressure sensor. The specific operating principle includes:
[0076] Sensor integration structure: Pressure sensor 1 is arrayed inside the contact surface of clamping plate 2, located in the subsurface layer of the clamping surface; the pressure sensing thin film is made of PEDOT:PSS conductive polymer flexible electronic material, which can conform to the curvature of the clamping surface to realize large-area pressure distribution detection; 4×4 sensing units are arranged to form an array, which can detect pressure distribution non-uniformity and avoid local overpressure.
[0077] 2) Mechanical structure support: The clamping surface is made of elastic material, which allows the pressure to be evenly transmitted to the sensor and protects the sensor from direct mechanical impact; the clamping force is effectively transmitted to the sensitive area of the sensor through a precisely designed elastomer; the sensor is wrapped with materials such as silicone or polyurethane to prevent oil and dust from entering, and to provide electrical isolation.
[0078] 3) Closed-loop control principle: Pressure sensor 1 → Signal conditioning circuit → Microcontroller → Propulsion cylinder 9 → Clamping plate 2 → Pressure sensor 1 (closed loop); The signal conditioning circuit detects the signal from pressure sensor 1, processes it, and wirelessly transmits it to the microcontroller. When the detected pressure exceeds the preset threshold, the microcontroller immediately reduces the drive signal; when the pressure is insufficient, it increases the drive signal of cylinder 9. A PID control algorithm is used to dynamically adjust the clamping speed and force according to the pressure change rate. The microcontroller and cylinder 9 can be connected by wire or wireless means. The signal conditioning circuit and microcontroller can be designed on the outer shell 10-5 of the middle telescopic rod. The line connecting the signal conditioning circuit on pressure sensor 1 can be connected through the inside of clamping plate 2.
[0079] 4) Implementation scheme: The pressure sensor monitors the pressure on the clamping surface; the air pressure is adjusted by the proportional valve to achieve continuous control of the clamping force; and the pressure-flow composite control is adopted to improve the system response speed.
[0080] The clamping part of the clamping plate 2 is arc-shaped, which makes it easier for the device to clamp the branch and prevent it from falling off. After the clamping plate 2 clamps the walnut branch, the electric eccentric vibrator 7 starts to operate, generating vibration force that is transmitted to the walnut branch, causing the walnut branch to sway, so as to achieve the purpose of walnut harvesting. The vibration frequency of the electric eccentric vibrator is adjustable and can be adjusted according to the walnut variety and maturity.
[0081] The specific embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
