Description

Technical Field

[0001] This utility model relates to the field of mushroom harvesting devices, and in particular to a harvesting device that can avoid root residue. Background Technology

[0002] The core purpose of mushroom harvesting equipment is to automate and intelligently harvest mushrooms. Mushroom cultivation typically takes place in high-temperature and high-humidity environments, and harvesting requires workers to bend over for extended periods, which is very strenuous. Automated equipment can replace manual labor, completing repetitive and heavy tasks. Through precise vision and mechanical control, the equipment can achieve standardized harvesting, such as picking only mushrooms that have reached a specific size and maturity, while avoiding damage to the mushrooms' appearance, thereby ensuring product consistency and high quality.

[0003] Existing mushroom harvesting devices are typically complex robotic systems that integrate multiple advanced technologies. These devices are usually equipped with industrial cameras and deep learning algorithms. Through image recognition technology, they can determine the size, maturity, and location of mushrooms from complex backgrounds and harvest them using flexible grippers or negative pressure suction cup clamps.

[0004] In the process of developing this application, the inventors discovered the following problems with the existing technology: For mushrooms with porous caps, such as morels, the negative pressure suction cup grippers of existing mushroom picking devices cannot create effective negative pressure, thus failing to effectively grasp them. While general flexible grippers can be used for effective picking, most existing flexible gripper picking devices pull the mushrooms up by the roots, taking away the soil and roots along with them. For morels, which have porous caps, the roots need to be cut off to prevent contamination of the mushrooms and affect their appearance. The aforementioned picking devices cannot meet these requirements.

[0005] Therefore, those skilled in the art have provided a harvesting device that avoids root residue, in order to solve the problems mentioned in the background art. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a harvesting device that avoids root residue, removes the roots completely, is clean and pollution-free, and is formed in one step.

[0007] To achieve the above objectives, the present invention provides the following technical solution: A harvesting device that avoids root residue includes a motor threaded rod structure, on which multiple connecting rods are rotatably connected, and multiple connecting rotating plates are rotatably connected to the multiple connecting rotating plates. Two joint structures are bolted to the multiple connecting rotating plates, and two flexible claw structures are connected to the two joint structures. A nut structure is rotatably connected in the middle of the multiple connecting rotating plates.

[0008] Furthermore, the nut structure is threadedly connected to the motor threaded rod structure, and two clamping knife structures are fixedly connected to the lower part of the multiple connecting rotating plates by bolts.

[0009] Furthermore, the flexible claw structure includes a flexible claw, a plurality of positioning posts are fixedly disposed below the flexible claw, and a magnetic block is fixedly disposed below the flexible claw.

[0010] Furthermore, the connector structure includes a connector block, on which a plurality of positioning holes are fixedly opened, and a magnetic suction hole is fixedly opened in the middle of the connector block.

[0011] Furthermore, a nut head is fixedly provided on the nut structure, and two connecting blocks are fixedly provided on both sides of the nut head, with two connecting holes fixedly provided on the two connecting blocks.

[0012] Furthermore, the clamping structure includes a blade head, on which a pin is fixedly disposed, and a blade is connected.

[0013] Furthermore, the motor threaded rod structure includes a fixing plate, on which a connecting column is fixedly connected, and a servo motor is fixedly connected below the fixing plate.

[0014] Furthermore, a threaded rod is fixedly connected to the servo motor, and a limit ring is fixedly provided on the threaded rod.

[0015] This utility model has the following beneficial effects: 1. The present invention proposes a harvesting device that avoids root residue. The device uses a motor connected to a threaded rod structure. The rotation of the threaded rod drives the nut structure to move up and down, which in turn drives the connecting rotating plate to rotate. This causes the clamping blade and soft claw to open and close, grabbing and cutting the mushroom, thus meeting the needs of morel mushrooms, which require root cutting.

[0016] 2. The present invention proposes a harvesting device that can avoid root residue. It uses different connection methods. The clamping blade uses a pin, which can not only quickly replace the worn blade, but also meet the lateral stress requirements when cutting the mushroom stem. The upper flexible clamping claw uses magnetic loading, and positioning pins are inserted into the connector around the perimeter to prevent misalignment under force. Attached Figure Description

Magnetic block 103 is used for quick installation.

Two bolts on the connecting rotating plate 3 fix a connector structure 2 and a cutter head 601. The cutter head 601 and connector structure 2 are placed vertically and connected by the same two screws. When the nut structure 4 moves upward, the connecting rotating plate 3 rotates outward, causing the flexible claw structure 1 and the clamping blade structure 6 to open, forming a scissor shape. Then, the blade 603 is aligned with the area above the mushroom root. The threaded rod 705 rotates in the opposite direction, and the nut structure 4... As the mushroom moves downwards, the flexible claw structure 1 and the clamping blade structure 6 close. After the blade is completely closed, the mushroom is cut off. The flexible claw 101 conforms to the mushroom stem and deforms to complete the grasping process. The entire device is operated by a robot, and the vision system locates the mushroom. The aforementioned robot and vision recognition system are mature technologies and are not part of the innovation of this design, so they will not be described in detail here. The blade 603 and the cutting head 601 are connected by a pin 602 for easy and quick replacement. The flexible claw 101 and the connector structure 2 are magnetically attached for easy replacement. The flexible claw 101 uses a silicone flexible gripper, which can effectively and safely grasp the mushroom.
