[0002] Black fungus is delicious and nutritious, and is a popular and common dish. my country has a huge production of black fungus. Currently, cultivation mainly involves two methods: ground planting and greenhouse bagging. Traditional manual harvesting is labor-intensive and inefficient, and can no longer meet the harvesting needs. Harvesting machines developed for ground-planted black fungus are mostly patented models. For example, Chinese patent CN109328886A discloses a black fungus harvesting machine, Chinese patent CN217884652U discloses a portable black fungus harvesting machine, and Chinese patent CN212487693U discloses a portable black fungus harvesting machine. Chinese patents have disclosed a black fungus harvesting machine, including Chinese patent CN215683855U which discloses an actuator clamping a black fungus harvesting robot, and Chinese patent CN114051892B which discloses a production line type black fungus harvesting machine. The black fungus harvesting method of these devices is mostly to rotate the fungus bag and use a harvesting scraper to scrape the black fungus off the fungus bag. The effect of "harvesting large ones and leaving small ones" is achieved by adjusting the distance between the harvesting scraper and the fungus bag.

Then, the rocker arm motor 13 stops, and the three harvesting heads 10 begin working under the drive of the harvesting drive motor 18. During operation, the harvesting blades of the irregularly shaped flexible harvesting roller 19 rotate relative to the flexible harvesting roller column 20. The harvesting blades of the irregularly shaped flexible harvesting roller 19 push the mushroom towards the flexible harvesting roller column 20, clamping the mushroom and removing it through relative rotation. The mushroom falls along the discharge chute of the harvesting head 10 into the mushroom recycling mechanism 3, while simultaneously being lifted... The servo motor 6 starts, and the picking head 10 moves upward at a constant speed to pick the wood ear fungus. After the picking head 10 has traveled the distance of one mushroom bag, the lifting servo motor 6 stops, the rotary motor 16 starts, and the rotary gear 17 drives the notched ring 14 to rotate 40 degrees clockwise. Then the rotary motor 16 stops, the lifting servo motor 6 starts, and the picking head 10 moves downward to the distance of one mushroom bag. Then the lifting servo motor 6 stops, the rotary motor 16 starts, and the rotary gear 17 drives the notched ring 14 to rotate 80 degrees counterclockwise. Then the rotary motor 16 stops, the lifting servo motor 6 starts, and the picking head 10 moves upward to the distance of one mushroom bag. After the last mushroom bag is picked, the three picking heads 10 rotate back to the initial position. Then the rocker arm motor 13 starts in the opposite direction to drive the picking rotating frame 15 back to the initial position. The lifting servo motor 6 drives the picking head 10 to descend to the initial working position at the bottom of the frame 1, waiting for the next mushroom bag string 4 to run to the working position, and continues to pick the next mushroom bag to complete the picking operation.

[0047] Before harvesting, the harvesting size of the harvesting machine is adjusted according to the growth of the wood ear fungus. During adjustment, the screw drive motor 35 drives the drive screw 36 to drive the harvesting head 10 to slide as a whole. The contact distance between the harvesting head 10 and the mushroom bag string 4 is controlled and adjusted by sliding. The size of the harvested wood ear fungus is controlled and adjusted by changing the size of the distance.

[0048] During the harvesting process, when the harvesting head 10 harvests the mushroom bag held by the clamping rod column 29, as the harvesting head 10 moves upward, the clamping rod opening top block 9 pushes the clamping rod opening block 25 of the upper clamping sleeve 27. This upward movement causes the upper clamping sleeve 27 to move upward along the guide groove on the upper clamping sleeve 27 while simultaneously rotating. During this process, the one-way locking structure between the upper and lower clamping sleeves 28 loosens. After unlocking, the lower clamping sleeve 28, under the action of the clamping lower torsion spring 30, causes the clamping rod column 29 to open, making room for the harvesting head 10. Simultaneously, due to the rotational action, the clamping rod opening block 25 on the upper clamping sleeve 27 rotates and slides out of the upper part of the clamping rod opening top block 9. Under the action of the clamping upper compression spring 26, the upper clamping sleeve 27 moves upward along the upper clamping rod opening top block 9. The guide notch on sleeve 27 rotates back to its original position. When the picking head 10 continues to move upward to pick the next mushroom bag after picking the current one, the inclined surface on the clamping rod return top block 8 connected to the lower part of the picking head 10 presses against the bearing on the side of the lower sleeve 28, so that the lower sleeve 28 overcomes the torque of the clamping lower torsion spring 30 and rotates into the one-way clamping structure between the upper sleeve 27 and the lower sleeve 28, and re-clamps the mushroom bag, thus making way for the work of the picking head 10. After the picking head 10 has picked all the mushroom bags on a mushroom bag string 4 in one go, the clamping shaft 31 rotates under the drive of the clamping drive motor 32, which drives the two sets of clamping rod columns 29 to open, waiting for the next mushroom bag string 4 to be picked to enter the picking station.

[0049] During the harvesting process, when the wood ear mushrooms fall into the recycling hopper 37, they are conveyed by the wood ear mushroom conveyor belt 38 and fall to the upper part of the separation plate seat 39. The vibrator 43 at the lower part of the separation plate seat 39 works, causing the wood ear mushrooms to fall and be discharged. At the same time, the debris mixed in with the wood ear mushrooms falling to the upper part of the separation plate seat 39 is blocked by the semi-circular protrusion 41, gathers and falls from the slag trough 42 into the interior of the debris collection box 40, completing the separation and removal of debris.

[0050] In summary, this invention employs a self-operated harvesting mechanism 2, a fungus recycling mechanism 3, and a fungus bag clamping and fixing mechanism 5 to achieve an automated harvesting structure for the fungus bag string 4. This automates the fixing, harvesting, and collection of fungus. Building upon the automated bag hanging and cultivation racks in factory cultivation, it automates fungus harvesting without requiring significant manpower. The invention utilizes a lifting and rotating harvesting structure, employing a lifting servo motor 6 to drive the lifting platform, and a harvesting rotating frame 15 in conjunction with a notched ring 14 to rotate the harvesting head 10. During harvesting, a clamping drive motor 32 drives the clamping shaft 31 to move the clamping rod. The column 29 clamps and fixes the mushroom bag string 4. Multiple harvesting heads 10 are provided. Through the reciprocating lifting and lowering motion of the harvesting heads 10, combined with the rotational repositioning of the notched ring 14, the harvesting and processing of the upper part of the mushroom bag string 4 can be efficiently completed. Compared with similar equipment, it has higher harvesting efficiency. The irregularly shaped flexible harvesting rod 19, in conjunction with the flexible harvesting rod column 20, flexibly clamps and harvests the mushrooms, effectively improving the integrity of the harvest. Furthermore, the harvesting heads 10 are slidably installed through a sliding groove structure. Driven by the screw drive motor 35 and the drive screw 36, the lateral spacing of the harvesting heads 10 can be controlled and adjusted. By changing the contact distance between the harvesting heads 10 and the mushroom bag string 4, the size of the harvested mushrooms can be adjusted. The control and adjustment greatly improve the working flexibility of the device. The mushroom bag clamping and fixing mechanism 5 adopts an autonomous avoidance structure. The clamping rod 29 is installed on the upper part of the clamping shaft 31 by flipping through the lower sleeve 28. The upper sleeve 27 and the lower sleeve 28 are connected by a one-way locking structure. Both the upper sleeve 27 and the lower sleeve 28 are provided with notched guide grooves on their upper parts. When the picking mechanism 2 moves upward and is moved up and down, the clamping rod opening top block 9 and the clamping rod opening block 25 on the side of the upper sleeve 27 support and guide, which can unlock the one-way locking structure. With the drive of the torsion spring, the clamping rod 29 can be flipped open to avoid the obstacle. After the change is completed, the clamping rod returns to the top. The support and guidance of the side guide bearings of block 8 and upper sleeve 27 enable the flipping and closing reset of the clamping rod column 29. The structure is simple and reliable. The entire operation is automatic without the need for additional drive structure and manual intervention, which greatly improves the ease of operation of the device. A separation plate seat 39 and a vibrator 43 are set at the rear of the fungus conveyor belt 38. A semi-circular protrusion 41 and a slag leakage trough 42 are set on the upper part of the separation plate seat 39. The semi-circular protrusion 41 is used to block and collect the debris inside the fungus. With the vibration of the vibrator 43, the debris is made to leak out from the slag leakage trough 42 and fall into the debris collection box 40. This can realize the separation of fungus and debris. The structure is simple and reliable, which is conducive to the subsequent packaging of fungus.
