Description

Technical Field

[0001] This utility model belongs to the field of black fungus cultivation technology, specifically relating to a black fungus harvesting device for hanging bag cultivation. Background Technology

[0002] Hanging cultivation is a commonly used method for the artificial cultivation of black fungus. In this process, the cultivation bags are first thoroughly sterilized and then inoculated with the required inoculum. After inoculation, these bags are placed in a suitable environment to allow the mycelium to grow successfully. Once the mycelium has grown to a certain extent, these bags are suspended inside a greenhouse, providing ample growing space for the black fungus through vertical cultivation. The suspended bags not only save ground space but also improve ventilation and light penetration, promoting the healthy growth of the black fungus.

[0003] Traditional black fungus harvesting relies primarily on manual labor, which has significant drawbacks such as low efficiency, high labor intensity, and high costs. To address these issues, a Chinese patent (CN202222077450.3) proposes an innovative harvesting device for hanging bag cultivation of black fungus. This device features two semi-cylindrical harvesting tools that surround the outside of the mushroom log. During harvesting, the harvester holds these two semi-cylindrical tools and slowly moves them from the highest point of the log to the lowest point, scraping and cutting the black fungus to harvest it. This significantly improves harvesting efficiency and reduces labor intensity and costs.

[0004] However, this harvesting device has some shortcomings in actual operation. For example, due to the lack of a support frame, its stability during operation is insufficient, which may lead to accidental damage to the wood ear mushrooms during harvesting, thus affecting the quality of the harvested mushrooms. In addition, when harvesters use this device for extended periods, they need to frequently bend over and hold the weight, which can easily lead to lower back fatigue, thereby affecting harvesting efficiency and making the overall harvesting process less efficient. Utility Model Content

[0005] In view of the problems of insufficient stability and high labor intensity of operators in existing harvesting devices in the background art, this utility model provides a black fungus harvesting device for hanging bag cultivation.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a black fungus harvesting device for hanging bag cultivation, comprising a harvesting trolley and a harvesting mechanism slidably disposed thereon, the harvesting mechanism comprising two open harvesting rings arranged on the same axis and connected thereto by multiple connecting rods, multiple paddles installed on each open harvesting ring, at least two sleeves disposed on the outer side of each open harvesting ring, the two open harvesting rings being sleeved on a round tube through the sleeves, the round tube being fixed on the harvesting trolley.

[0007] As a further supplement to the above technical solution, a threaded rod is fixed on each of the connecting rods by two nuts. A roller is installed on the threaded rod located on one side of the open picking ring. The roller abuts against the surface of the mushroom stick to ensure the stability of the picking process of the picking mechanism.

[0008] As a further supplement to the above technical solution, a circular hole is provided on the picking cart corresponding to the picking mechanism, and a collection bucket is provided directly below the circular hole. Limiting arc rods are symmetrically arranged on the picking cart, and the limiting arc rods are used to fix the collection bucket.

[0009] As a further supplement to the above technical solution, a funnel-shaped opening is provided on the opening picking ring, a notch is provided on the funnel-shaped opening, and a curtain is slidably provided on the funnel-shaped opening. The curtain covers the top of the round hole to prevent the falling black fungus from flying outward.

[0010] As a further supplement to the above technical solution, a handle is provided on the connecting rod, which is used to facilitate raising the height of the harvesting mechanism.

[0011] As a further supplement to the above technical solution, a strip-shaped hole is provided at one end of the paddle, and the paddle is threadedly connected to the open picking ring by a bolt passing through the strip-shaped hole.

[0012] For further explanation and limitation of the above technical solution, the multiple paddles located on each of the opening picking rings are arranged radially, and the blade of each paddle faces the center of the opening picking ring.

[0013] As a further supplement to the above technical solution, a pin is provided on the sleeve, the pin is connected by a pull rod, and a matching pin hole is opened on the round tube. The pin is used to fix the position of the sleeve and the round tube.

[0014] As a further supplement to the above technical solution, a rubber pad is fitted onto the circular tube, and the rubber pad is used to reduce the impact force caused by the falling of the picking mechanism on the picking cart.

[0015] To further explain and define the above technical solution, a U-shaped plate is provided at the top of the circular tube, and a fixing plug is provided on the U-shaped plate. The fixing plug penetrates the U-shaped plate and is embedded inside the circular tube. The U-shaped plate is used to enhance the stability of the circular tube structure.

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] 1. This utility model, by installing a support structure composed of round tubes on the harvesting cart, allows the harvesting mechanism to be slidably mounted on the round tubes via a sleeve. This constrains the movement direction of the harvesting mechanism, greatly improving the stability of the harvesting process, ensuring the harvesting efficiency and quality of black fungus, and reducing losses caused by improper operation. At the same time, it eliminates the need for harvesters to frequently bend over and carry heavy loads, significantly reducing the workload for harvesters.

[0018] 2. This utility model has a collection bucket installed on the picking cart. The black fungus scraped off by the picker falls directly into the collection bucket. Furthermore, a baffle is set between the collection bucket and the open picking ring. The black fungus falls into the collection bucket through the channel formed by the baffle, which effectively prevents the black fungus from scattering and being lost, and ensures that the collection process is clean and efficient.

[0019] 3. The lever used in this utility model can be adjusted in position through the strip hole and bolt, which can be adapted to black fungus of different sizes; the position of the threaded rod can be adjusted by the cooperation of the nut, so that the roller can adapt to the width of the mushroom stick, ensuring the wide applicability of the device to different planting scenarios and improving practical efficiency.

[0020] 4. The rubber pads installed on the round tubes in this utility model can effectively reduce the impact of the harvesting mechanism on the harvesting cart, extend the service life of the equipment, and the U-shaped plates installed between the round tubes enhance the stability of the overall structure and further improve the smoothness of the harvesting process.

[0026] To further illustrate the technical solution of this utility model, the following description is in conjunction with the appendix. Figures 1 to 4 The present invention will be further described in detail through three embodiments.

[0027] Example 1

[0028] This embodiment provides a black fungus harvesting device for hanging bag cultivation, as shown in the attached image. Figure 1 and attached Figure 2 As shown, the harvesting device includes a harvesting trolley 1 and a harvesting mechanism 2 slidably mounted on it. The harvesting mechanism 2 specifically includes two open harvesting rings 201 arranged on the same axis, connected by multiple connecting rods 202 to form a stable frame. Each open harvesting ring 201 is equipped with multiple paddles 203, and at least two sleeves 204 are provided on the outer side of each open harvesting ring 201. The two open harvesting rings 201 are fitted onto a circular tube 3 via sleeves 204, and the circular tube 3 is fixed to the harvesting trolley 1. A threaded rod 5 is fixed to each connecting rod 202 by two nuts 4. A roller 501 is mounted on the threaded rod 5 on one side of the open harvesting ring 201. During the downward movement of the harvesting mechanism 2, the roller 501 abuts against the surface of the mushroom log to ensure the stability of the harvesting process. Furthermore, a handle 205 is provided on the connecting rod 202; gripping the handle 205 raises the harvesting mechanism 2 back up from the harvesting trolley 1. We have a slotted hole 206 at one end of the pick 203. The pick 203 is threadedly connected to the open picking ring 201 through the slotted hole 206 by a bolt 207, so as to realize the picking of black fungus of different sizes. The multiple picks 203 located on each open picking ring 201 are arranged radially, and the blade of each pick 203 faces the center of the open picking ring 201, so as to ensure efficient peeling of black fungus during the picking process.

[0029] Example 2

[0030] Based on Example 1, as shown in the appendix Figure 3As shown, we have a circular hole 101 on the picking cart 1 corresponding to the picking mechanism 2. A collection bucket 102 is set directly below the circular hole 101. The black fungus scraped off by the picking mechanism 2 falls directly into the collection bucket 102, reducing the labor intensity of the picking personnel. In addition, we have symmetrically set a limiting arc rod 103 on the picking cart 1. The limiting arc rod 103 is used to fix the position of the collection bucket 102 to prevent the bucket opening from being misaligned with the circular hole 101 when the collection bucket 102 moves with the picking cart 1, which would affect the subsequent collection work.

[0031] To ensure all the black fungus falls into collection bucket 102, see attached... Figure 1 As shown, we have a funnel-shaped opening 6 on the open picking ring 201, and a notch 601 on the funnel-shaped opening 6. A curtain 602 is slidably installed on the funnel-shaped opening 6, covering the round hole 101. A channel is formed between the open picking ring 201 and the picking cart 1, and the black fungus falls into the collection bucket 102 through this channel.

[0032] Example 3

[0033] Based on Embodiment 1 and Embodiment 2, as shown in the appendix Figure 2 As shown, a pin 208 is provided on the sleeve 204. The pins 208 are connected by a pull rod 209, allowing the two pins 208 to move synchronously. A matching pin hole 301 is provided on the round tube 3. The pins 208 are used to fix the positions of the sleeve 204 and the round tube 3. Further, as shown in the attached... Figure 3 As shown, a rubber pad 302 is fitted onto the circular tube 3 to reduce the impact force caused by the harvesting trolley 1 when the harvesting mechanism 2 falls. (See attached diagram) Figure 4 As shown, we have a U-shaped plate 303 on the top of the round tube 3. The U-shaped plate 303 is inserted into the round tube 3 through the fixing plug 304 and fixed to the top of the four round tubes 3, thereby enhancing the structural stability of the four round tubes 3.

[0034] Its working principle:

[0035] The harvester moves the harvesting cart 1 to the front of the mushroom stick hanging bag line, aligns the hanging bag line with the opening of the open harvesting ring 201, and pushes the harvesting cart 1 again so that the hanging bag line moves into the inside of the open harvesting ring 201. The baffle curtain 602 is pulled, and then the handle 205 is grasped. The pin 208 is pulled out through the lever 209, and the open harvesting ring 201 is lowered. After the paddle 203 on the open harvesting ring 201 contacts the black fungus on the mushroom stick, the handle 205 is released. Under its own gravity and with the constraint of the sleeve 204, the harvesting mechanism 2 slides down along the round tube 3 onto the harvesting cart 1. During this process, the blade of the paddle 203 scrapes and cuts the black fungus, which falls into the collection bucket 102 through the channel formed by the baffle curtain 602. During this process, the roller 501 remains in contact with the mushroom stick to ensure the stability of the harvesting process.

[0036] Before use, the position of the picker 203 is adjusted according to the size of the black fungus to be harvested. Moving the picker 203 towards the center of the opening harvesting ring 201 and tightening the bolt 207 adapts the picker 203 to smaller black fungus; conversely, moving the picker 203 in the opposite direction and tightening the bolt 207 adapts it to larger black fungus. Furthermore, the position of the roller 501 is adjusted according to the width of the mushroom log. Moving the threaded rod 5 towards the mushroom log adapts to narrower logs, and moving it in the opposite direction adapts to wider logs. After adjustment, the threaded rod 5 is fixed in place by the two nuts 4.

It will be apparent to those skilled in the art that the specific embodiments of this utility model are not limited to the details of the exemplary embodiments described above. Furthermore, without departing from the spirit or essential characteristics of this utility model, the inventive concept and design ideas of this utility model can be implemented in other specific forms, and these should be equivalently included within the protection scope disclosed in the technical solution of this utility model.
