Description

Technical Field

[0001] This utility model relates to the field of fruit harvesting technology, specifically a remote-controlled fruit stem cutting structure. Background Technology

[0002] Fruit bagging is a method of covering young fruit with bags of different materials, mainly including paper, PE plastic film, and non-woven fabric. This method improves the smoothness of the fruit surface by isolating it from pests, diseases, pesticide pollution, and wind and rain damage, regulates the fruit's microenvironment, reduces fruit cracking and drop, and enhances marketability. Fruit bagging is usually done manually or by a bagging robot. After bagging, the fruit can be harvested using a harvesting robot or manually. Manual harvesting is time-consuming and labor-intensive, hindering the modernization of orchards. Harvesting robots often require identification, positioning, grasping, separating, and retrieval. When changing harvesting targets, the robotic arm needs to frequently change the position of its end effector to reach the next harvesting point before continuing its work, resulting in low efficiency and potentially poor harvesting results. Furthermore, some fruit trees have dense foliage, which can interfere with the robot's identification system, leading to missed harvests. Manual harvesting of these missed fruits is usually necessary, making the overall process complex, inefficient, and inconvenient. Utility Model Content

Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-4 In this embodiment of the utility model, the remote-controlled fruit stem cutting structure includes: The system includes a base 100 that can support the surface of the fruit, a connecting frame 200, a cutting mechanism 400 that can cut the fruit stem, a locking mechanism 300 that can position the cutting mechanism 400, and a remote control device that can remotely control the locking mechanism 300. The connecting frame 200 is fixedly connected to the base 100, the locking mechanism 300 is fixedly connected to the connecting frame 200, and the remote control device is fixedly connected to the base 100.

[0016] Specifically, when bagging the fruit, the bottom support 100 is used to support the bagged fruit, so that the fruit stem is located at the connecting frame 200. In the initial state, the locking mechanism 300 is used to lock the cutting mechanism 400 in place. When the fruit needs to be harvested, the locking mechanism 300 can be instructed by a remote control device, so that the locking mechanism 300 will no longer lock the cutting mechanism 400, and the cutting mechanism 400 will automatically cut the fruit stem, allowing the fruit to fall naturally. The fallen fruit can be collected by using a harvesting robot in the existing technology, or by manually using nets or other items to catch the fallen fruit, thereby improving harvesting efficiency.

[0017] Example 1 like Figure 2-3 As shown, in this embodiment, the shearing mechanism 400 includes: The device includes a blade holder 410 that can engage with the locking block 320, multiple tension springs 420 that pull the blade holder 410 to move, and a blade 430 that can cut the fruit stem. The blade holder 410 is slidably engaged with the top surface of the connecting frame 200. The top surface of the connecting frame 200 has multiple sliding grooves, and the bottom surface of the blade holder 410 is fixedly connected to multiple sliders. The sliders are slidably engaged in the interior of adjacent sliding grooves. A locking slot is provided on one side of the blade holder 410. One end of each of the multiple tension springs 420 is fixedly connected to one end of the connecting frame 200, and the other end is fixedly connected to the blade holder 410. The blade 430 is detachably connected to the blade holder 410. The top surface of the connecting frame 200 has a connecting groove for accommodating the fruit stem. The top surface of the base 100 has a fruit stem groove 101. The inner wall of the connecting groove of the connecting frame 200 has a receiving opening 201, and a fruit stem holder 440 is movably engaged inside the receiving opening 201.

[0018] In this embodiment, while bagging the fruit stem, the fruit stem is passed through the fruit stem groove 101 on the base 100 and through the connecting groove on the connecting frame 200. The fruit stem support 440 is pushed to move, so that part of the fruit stem support 440 is retracted into the receiving opening 201, thereby making the connecting groove unobstructed and facilitating the fruit stem to pass through the connecting groove. Then, the fruit stem support 440 can be reset to close the connecting groove, leaving the fruit stem inside the connecting groove. In the initial state, the blade holder 410 is fixed by the locking mechanism 300. After the locking mechanism 300 releases the blade holder 410, the blade holder 410 can be driven by multiple tension springs 420 to move along the top inclined surface of the connecting frame 200, so that the blade 430 cuts the fruit stem. The connecting frame 200 and the base 100 are integrally molded plastic parts. The top surface of the connecting frame 200 is inclined, so that the blade 430 can cut the fruit stem at an angle, improving the cutting effect of the blade 430 on the fruit stem.

[0019] like Figure 1-2 As shown, in this embodiment, the locking mechanism 300 includes: The telescopic electromagnet 310, which can adjust the position of the locking block 320 as needed, and the locking block 320, which can lock the position of the shearing mechanism 400, are fixedly connected to the telescopic electromagnet 310 and the connecting frame 200. The connecting frame 200 has a connecting hole at the top, and the movable end of the telescopic electromagnet 310 is fixedly connected to the support arm. The support arm is slidably sleeved inside the connecting hole. The locking block 320 is fixedly connected to the movable end of the telescopic electromagnet 310, and the locking block 320 is movably locked inside the slot. The remote control device includes an infrared receiver, a voltage regulator, a main chip, an infrared remote controller, a power supply, and a MOSFET.

[0020] In practical implementation, the telescopic electromagnet 310 is an existing device. A remote control device is installed on the base 100. The remote control device is powered by a power supply and uses a voltage regulator to power the main chip. The infrared receiver head is connected to the main chip to receive infrared signals. The MOS is used to load the current. The infrared remote control sends infrared signals, which are decoded by the main chip and then controlled by the IO port to switch the MOS tube, thereby realizing the extension and retraction of the telescopic electromagnet 310. In the initial state, the telescopic electromagnet 310 uses the locking block 320 to insert into the slot to fix the position of the blade holder 410. After the telescopic electromagnet 310 receives the signal from the infrared remote control device, it drives the locking block 320 to retract and disengage from the slot, so that the blade holder 410 and the blade 430 are driven by the tension spring 420 to cut the fruit stem. The base 100 and the connecting frame 200 in this application can be mass-produced by 3D printing, mold production, etc., to reduce costs. The power supply can be a button battery, making the overall cost of this application low and suitable for large-scale harvesting of high-end tree fruits.

[0021] In this embodiment, when manually bagging the fruit, after tying the bag opening tightly, the fruit stem can be placed in the fruit stem groove 101, so that the base 100 and the connecting frame 200 are located above the fruit and the tightly tied opening of the bag. After harvesting, the base 100, connecting frame 200, etc. can be removed from the fruit bag for reuse.

[0022] Example 2 Based on Embodiment 1, the guide rod 210 and the rebound spring 211 are provided to facilitate the reset of the fruit stem support 440.

[0023] like Figure 2-3 As shown, in this embodiment, a guide rod 210 is fixedly connected to one end of the storage opening 201, and an insertion port is provided on one side of the fruit stem support 440. The guide rod 210 is movably inserted into the insertion port, and a spring 211 is movably sleeved on the outer wall of the guide rod 210. The spring 211 is located between one end of the storage opening 201 and the fruit stem support 440.

[0024] In practice, when installing the base support 100 on the fruit, the fruit stem support 440 can be moved to retract into the storage opening 201. After the fruit stem support 440 is released, the fruit stem support 440 can be driven by the rebound spring 211 to reset and close the connecting groove. The guide rod 210 guides and limits the fruit stem support 440, making the fruit stem support 440 more stable when moving.
