Technical Field
[0001] This patent relates to the field of agricultural machinery technology, and in particular to a clamping claw structure with a shock-absorbing connection function used in an automated vibration picking device. Background Art
[0002] With the continuous advancement of agricultural automation and intelligence, vibration picking technology, as an efficient means of fruit picking, has been widely used in the harvesting process of economic crops such as olives, walnuts, and citrus. However, the current commonly used vibration picking clamping devices generally have many technical bottlenecks: such as poor clamping stability, which is easy to slip or loosen during the vibration process; slow response of the clamping jaws, complex structure, easy wear, and poor reliability; insufficient adaptability, making it difficult to adapt to different tree species and branch diameters; lack of effective buffering and shock-absorbing structure, which can easily lead to fatigue damage and affect the life of the clamping jaws and equipment; low vibration energy transmission efficiency, which affects the fruit shedding effect. The above problems seriously restrict the operating efficiency and promotion and application of vibration picking technology. Therefore, it is urgent to develop a clamping jaw structure with a compact structure, rapid response, high clamping stability, good buffering and shock-absorbing performance, and strong versatility, so as to comprehensively improve the reliability, efficiency and equipment adaptability of vibration picking operations.
[0003] In order to overcome the problems of loose clamping, slow response, and easy damage caused by rigid structural connection in the existing vibrating picking device's clamping structure, especially the phenomenon that the clamping jaws are prone to increased wear, connection fatigue, and branch slippage under high-frequency vibration operation conditions, this patent proposes a clamping jaw structure with a shock-absorbing connection function, which is suitable for vibrating picking devices to improve the working stability and structural reliability of the device.
[0004] In order to achieve the above purpose, the technical solution adopted by this patent is: a clamping jaw structure for a vibrating picking device with a shock-absorbing connection function, including a clamping jaw body, a vibration mechanism, a shock-absorbing connection flange, a pneumatic push rod and a connecting rod; the clamping jaw body includes a fixed clamping jaw and a movable clamping jaw, the fixed clamping jaw is fixedly connected to the clamping jaw body, the movable clamping jaw is hinged to the clamping jaw body through a rotating shaft assembly, and is connected to the connecting rod, the connecting rod is connected to the pneumatic push rod, the pneumatic push rod is connected to the clamping jaw structure through a cylinder body, and its output end is connected to the connecting rod.
[0005] The vibration mechanism includes a DC motor and an eccentric wheel. The eccentric wheel is installed on the output shaft of the DC motor. The vibration mechanism is arranged below the clamping jaw body and connected to the clamping jaw structure to achieve periodic eccentric motion.
[0006] Preferably, the vibration mechanism is arranged between the clamping jaw body and the shock-absorbing connecting flange, and a shock-absorbing structure is arranged between the two. The shock-absorbing structure includes a rubber pad, a silicone pad or an elastic shock-absorbing plate, which is used to absorb the impact load formed during the eccentric vibration process and control the vibration transmission path.
[0007] Preferably, the eccentric wheel is a replaceable structure, and its eccentric distance is adjustable, which is used to adjust the vibration intensity to adapt to different fruit tree picking requirements.
[0008] Preferably, the shock absorbing structure includes a rubber-metal composite cushion layer, which is arranged between the bottom of the vibration mechanism and the shock absorbing connection flange and is fixed by bolt connection.
[0009] Preferably, the overall clamping claw structure adopts a modular design, including a clamping module, a vibration module, a shock absorbing module and a driving module. Each module is independently arranged, which can achieve rapid disassembly and maintenance, thereby improving the adaptability and scalability of the system.
[0010] Compared with the existing technology, the beneficial effects of this patent are: first, by providing a driving mechanism composed of a pneumatic push rod and a connecting rod, the rapid response and efficient clamping of the opening and closing action of the clamping jaws are achieved, the operating speed is improved, the clamping stability is enhanced, and the crop damage rate caused by loose clamping is effectively reduced; secondly, an independent vibration drive unit is provided, and a DC motor is combined with an eccentric wheel to generate mechanical vibration with adjustable frequency and amplitude. The vibration force can be accurately transmitted to the branches during the clamping process, thereby improving the fruit shedding efficiency; thirdly, the vibration unit is arranged between the clamping jaw and the connecting flange, and vibration isolation is performed through the shock-absorbing connecting flange, which not only effectively controls the vibration direction, but also reduces the impact of vibration on the connecting mechanism and the robotic arm, thereby extending the life of the entire machine; in addition, the overall clamping jaw structure adopts a modular design, which is easy to install and simple to maintain. It is suitable for the picking needs of different crops, such as winter dates, walnuts, olives, etc., and has strong scene versatility and promotion value. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The following description is intended to explain this patent so that those skilled in the art can implement the technical solutions of this patent. The following embodiments are merely preferred forms, and those skilled in the art may make equivalent substitutions or modifications without departing from the spirit and substance of this patent.
[0016] Reference Figures 1 to 3 As shown, a clamping claw structure for a vibrating picking device with a damping connection function comprises a clamping claw body (1), a vibrating mechanism (2), a damping connection flange (3), a pneumatic push rod (4) and a connecting rod (5).
[0017] The clamping jaw body (1) includes a fixed clamping jaw (101) and a movable clamping jaw (103), wherein the fixed clamping jaw (101) is fixedly connected to the clamping jaw body (1). The movable clamping jaw (103) is rotatably connected to the clamping jaw body (1) via a rotating shaft assembly (104). The movable clamping jaw (103) is connected to a connecting rod (5), and the connecting rod (5) is connected to a pneumatic push rod (4), which is arranged on the clamping jaw structure. The above connection relationship enables the movable clamping jaw (103) to rotate around the rotating shaft assembly (104) when the pneumatic push rod (4) makes a linear motion, thereby realizing a clamping or opening state relative to the fixed clamping jaw (101).
[0018] A clamping gasket (102) is provided between the fixed clamping jaw (101) and the movable clamping jaw (103). The clamping gasket (102) is made of a flexible material and is attached to the clamping surface to form a contact buffer layer.
[0019] The vibration mechanism (2) is arranged below the clamping jaw body (1), and specifically comprises an eccentric wheel (201) and a DC motor (202). The DC motor (202) is mounted at the bottom of the clamping jaw body (1), and its output shaft is connected to the eccentric wheel (201). The rotation of the motor drives the eccentric wheel (201) to rotate eccentrically. The eccentric rotation of the eccentric wheel (201) forms a periodic offset, which is transmitted to the clamping jaw body (1) through the connection relationship, thereby causing the entire clamping jaw structure to vibrate.
[0020] The clamping jaw body (1) is connected to the mechanical arm or the device body via a shock-absorbing connecting flange (3). A shock-absorbing filler (301) is provided inside the shock-absorbing connecting flange (3). The shock-absorbing filler (301) can be a rubber pad, a silicone pad or an elastic composite material. The shock-absorbing filler (301) absorbs part of the impact load of the clamping jaw structure during vibration through compression deformation, thereby reducing the energy transmitted to the device body by the vibration.
[0021] The clamping jaw structure adopts a modular design. The clamping jaw body (1), the vibration mechanism (2), the shock-absorbing connection flange (3) and the pneumatic push rod (4) constitute independent modules. The modules are assembled through standard connecting parts, which facilitates the disassembly, replacement and maintenance of the units. The overall structure has strong adaptability and is suitable for vibration picking scenarios of various crops, including but not limited to winter jujube, walnuts, olives, etc.
[0022] The above description is merely a preferred embodiment of this patent and should be understood as not being limited to the above embodiments. For those skilled in the art, any equivalent substitutions, improvements, or modifications made without departing from the spirit and substance of this patent should be included within the scope of protection of this patent. The scope of protection claimed shall be determined by the appended claims and their equivalents.
