Description

Technical Field

[0001] This utility model relates to the technical field of oyster mushroom cultivation equipment, specifically to a oyster mushroom cultivation bag perforator. Background Technology

[0002] In the cultivation of oyster mushrooms, oyster mushroom bags (cultivation bags) are an important carrier for mycelial cultivation and growth. Punching holes in the oyster mushroom bags is indispensable. On the one hand, mycelial growth requires sufficient oxygen and the release of carbon dioxide; puncturing ensures gas exchange within the bag, maintaining a suitable gaseous environment. On the other hand, puncturing helps regulate humidity within the bag, preventing excessive humidity from breeding unwanted microorganisms.

[0003] During the cultivation of oyster mushrooms, the bags often need to be perforated multiple times, especially on both sides. Different growth stages have different requirements for oxygen and other conditions. For example, during the mycelial germination period, rapid growth period, and fruiting period, holes need to be perforated in a timely manner to meet the dynamic needs of oyster mushroom growth.

[0004] Regarding the process of punching holes in oyster mushroom bags during the cultivation of oyster mushrooms in oyster mushroom houses, the inventor believes that the following technical problems exist:

[0005] (1) Oyster mushroom houses are usually compact and difficult to accommodate large hole punchers; therefore, small and convenient hole punchers are suitable hole punching tools for compact oyster mushroom houses.

[0006] (2) When the existing punching tool pulls out the punching head after punching, the film of the oyster mushroom bag is prone to sticking to the punching head. Once the film is pulled and damaged by the punching head, it will not only affect the sealing and integrity of the oyster mushroom bag, but may also lead to contamination by miscellaneous fungi, reducing the yield and quality of oyster mushroom cultivation.

[0007] Therefore, how to solve the above-mentioned technical problems and develop a small and convenient punching tool, and how to avoid the situation where the film of the mushroom bag sticks to the punching head and is pulled and damaged by the punching head when the punching tool is used for punching operations.

[0008] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0026] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] See Figures 1-5 To address the problems mentioned in the background section, this utility model provides a oyster mushroom cultivation bag perforator to solve the aforementioned technical problems. The technical solution is as follows:

[0028] A oyster mushroom cultivation bag punching device includes: a handle 110, a punching disc 130, a punching head assembly, a reset disc 160, a guide post 120, and a reset spring 150;

[0029] The grip 110 is detachably and fixedly connected to the top surface of the punching plate 130; the punching plate 130 is provided with a plurality of first arc-shaped holes 131 arranged in a circular array;

[0030] A punching head assembly is fixedly attached to each of the first arc-shaped holes 131; the punching head assembly includes a punching rod 141, a baffle 144 and a nut 143; the tail of the punching rod 141 is a spike, and the head of the punching rod 141 is provided with a first external thread 142.

[0031] The head of the punching rod 141 is inserted into the first arc-shaped hole 131; the baffle 144 is fixed on the punching rod 141 and located below the punching plate 130; the nut 143 is locked and screwed onto the head of the punching rod 141 and located above the punching plate 130.

[0032] The reset plate 160 is circumferentially fixed with multiple guide posts 120 arranged in a circular array; the guide posts 120 slide through the perforated plate 130.

[0033] The reset spring 150 is sleeved on the guide post 120; one end of the reset spring 150 is fixedly connected to the perforated plate 130, and the other end of the reset spring 150 is connected to the reset plate 160.

[0034] The reset plate 160 is provided with a plurality of second arc-shaped holes 161 corresponding to the positions of the first arc-shaped hole 131; the tail of the piercing rod 141 passes through the second arc-shaped hole 161.

[0035] In this embodiment, a connecting short tube 170 is fixedly connected to the top surface of the punching disc 130, and the inner cavity of the connecting short tube 170 is provided with an internal thread; the end of the grip 110 is provided with a second external thread 111; the grip 110 is detachably and fixedly connected to the inner thread of the inner cavity of the connecting short tube 170 through the second external thread 111.

[0036] When the grip bar 110 needs to be replaced or maintained due to long-term use, the grip bar 110 can be disassembled and replaced by loosening the threaded connection between the connecting short tube 170 and the end of the grip bar 110.

[0037] In this embodiment, a limiting block is fixedly connected to the end of the guide post 120; the limiting block is fixedly connected to the end of the guide post 120 to prevent the guide post 120 from slipping off the punching plate 130.

[0038] In this embodiment, multiple anti-slip ridges are provided at intervals along the axial direction on the peripheral wall of the grip 110; the anti-slip ridges increase the friction force for the operator to grip the grip 110.

[0039] The method of using the oyster mushroom cultivation bag puncher provided in this embodiment of the invention is as follows:

[0040] (1) Preparation: Select a suitable punching head assembly (such as punching rods of different diameters) according to the type of cultivation bag to be punched; at the same time, the assembly position of the punching rod 141 in the first arc hole 131 can be adjusted by loosening the nut 143. After adjusting to the appropriate position, tighten the nut 143 to fix the punching head assembly on the punching plate 130.

[0041] (2) Punching: The operator holds the handle 110 and places the reset plate 160 against the surface of the cultivation bag. At this time, the reset spring 150 is in its natural state. Press down the handle 110, and the puncturing plate 130 drives the puncturing head assembly to move downward. The puncturing rod 141 continues to pass through the second arc-shaped hole 161 of the reset plate 160 and pierces into the cultivation bag. During this process, the reset plate 160 remains stationary due to the obstruction of the cultivation bag, while the puncturing plate 130 continues to move downward, and the reset spring 150 is compressed.

[0042] (3) Punching and resetting: When the puncturing rod 141 reaches the required puncturing depth, stop pressing down the gripping rod 110; at this time, release the gripping rod 110, and under the elastic force of the reset spring 150 returning to its original state, the reset plate 160 pushes the puncturing plate 130 upward, driving the puncturing rod 141 out of the cultivation bag;

[0043] Since the reset plate 160 is always in contact with the surface of the cultivation bag and the spring force of the reset spring 150 is uniform, the punching rod 141 is pulled out smoothly, which effectively prevents the film on the surface of the cultivation bag from adhering to the punching rod 141 and prevents the film from being pulled and damaged.

[0044] (3) Subsequent adjustments and reuse: If it is necessary to punch holes in other types of cultivation bags, repeat the above preparation work and replace the appropriate punching head assembly.

[0045] The oyster mushroom cultivation bag punching device provided by this utility model has the following beneficial effects: This utility model designs an oyster mushroom cultivation bag punching device. This punching device has a small and simple structure, and is convenient and flexible to operate. When punching, the cooperation of the reset plate and the reset spring can minimize the possibility of the oyster mushroom bag film sticking to the punching head, which would cause the film to be pulled and damaged by the punching head.
