Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of sealing caps for edible mushroom sticks, specifically a sealing cap for edible mushroom sticks. Background Technology
[0002] Edible fungi refer to large, edible mushrooms (macrofungi), commonly known as mushrooms. China has more than 350 known edible fungi, most of which belong to the Basidiomycota subphylum. Common examples include: shiitake mushrooms, straw mushrooms, button mushrooms, wood ear mushrooms, silver ear mushrooms, monkey head mushrooms, bamboo fungus, matsutake mushrooms, button mushrooms, red mushrooms, reishi mushrooms, cordyceps, truffles, white lingzhi mushrooms, and porcini mushrooms.
[0003] Traditional mushroom log sealing caps are relatively simple in design, with a single sealing structure. Furthermore, different types and specifications of mushroom logs vary in shape and size. Traditional sealing caps are often not versatile enough to adapt to various mushroom logs, requiring producers to purchase different sealing caps for different mushroom logs, which increases production costs. Therefore, we have proposed a new mushroom log sealing cap. Utility Model Content
[0004] The purpose of this utility model is to provide a sealing cap for edible mushroom sticks, so as to solve the problem in the background art that the sealing cap cannot be adapted to seal edible mushroom sticks of different sizes, requiring producers to purchase different sealing caps for different mushroom sticks, which increases production costs.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a sealing cap for edible mushroom sticks, comprising a sealing cap body and a retaining plate. The bottom surface of the sealing cap body is provided with grooves around its perimeter. A return spring is fixedly installed on one side of the groove surface. A connecting plate is fixedly installed on one side of the return spring surface. A limiting plate is fixedly installed on one side of the connecting plate surface. A rotating plate is movably connected to one side of the limiting plate surface. Bearings are rotatably connected to both sides of the rotating plate surface. The retaining plate is fixedly engaged with one side of the bearing surface. A sealing rubber gasket is provided on one side of the retaining plate surface. A retaining ring is fixedly installed on the upper surface of the retaining plate.
[0006] As a further description of the above technical solution:
[0007] The sealing cap body has a slot inside and through holes around the top.
[0008] As a further description of the above technical solution:
[0009] The card plate is fan-shaped and evenly distributed around the bottom of the sealing cover body. It is installed around the card slot surface by rotating the plate.
[0010] As a further description of the above technical solution:
[0011] The limiting plate is U-shaped, and a groove is provided on the inner wall of the limiting plate. The plate can be adjusted by sliding on the surface of the groove through a rotating plate.
[0012] As a further description of the above technical solution:
[0013] The clamping plates are adjusted by rotating on the surface of the limiting plate via a rotating plate and bearings, so that the clamping plates are distributed vertically around the bottom of the clamping slot.
[0014] As a further description of the above technical solution:
[0015] The limit plate is adjusted by extending and retracting at the bottom of the sealing cover body via a reset spring.
[0016] As a further description of the above technical solution:
[0017] The retaining rings are evenly distributed at the center of the upper part of the retaining plate, and move synchronously with the limiting plate on the bottom surface of the sealing cover body through the return spring.
[0018] As a further description of the above technical solution:
[0019] The surface of the retaining ring is also equipped with a sealing rubber gasket.
[0020] As a further description of the above technical solution:
[0021] The card slot surface is equipped with a filter membrane, which is installed on the surface of the through hole to ensure gas exchange and filter out bacteria in the air.
[0022] Compared with the prior art, the beneficial effects of this utility model are:
[0023] 1. The sealing cap for edible mushroom logs has a sealing rubber pad on the surface of the card plate. Since edible mushroom logs come in different sizes, when the logs are small, simply open the card plate at the bottom of the sealing cap body, attach the top of the mushroom log to the top of the inner side of the slot, and then fold the card plate back. When installing the sealing cap, the card plate can fit tightly against the surface of the log, forming multiple sealing defenses in conjunction with the overall structure of the sealing cap body. This effectively blocks the intrusion of external bacteria, dust, and moisture, creating a stable and clean environment for the growth of edible mushrooms, significantly reducing the risk of log contamination, and ensuring the yield and quality of edible mushrooms.
[0024] 2. When sealing larger edible mushroom logs, this sealing cap utilizes bearings to rotate the clamping plate, making the clamping plate and the bottom of the sealing cap body perpendicular. The mushroom log is then clamped and secured by a retaining ring. Simultaneously, a return spring generates a pushing force on the limiting plate, effectively driving the retaining ring to firmly clamp the mushroom log, achieving a sealing effect. This allows the sealing cap to adapt to mushroom logs of different shapes and sizes, achieving a good seal regardless of the log's diameter or shape. This reduces the cost for producers to purchase multiple sealing caps to fit different mushroom logs, thus lowering production input. Attached Figure Description

[0036] This utility model provides a sealing cap for edible mushroom logs, suitable for mushroom logs of different sizes. It allows for adjustable tightness to accommodate different log sizes, eliminating the need for producers to purchase separate sealing caps for different logs, thus reducing production costs and effectively improving the practicality of the device. Please refer to [link / reference]. Figures 1 to 6 The system includes a sealing cover body 100 and a retaining plate 200. The bottom surface of the sealing cover body 100 has grooves 202 around its perimeter. A return spring 203 is fixedly installed on one side of the groove 202. A connecting plate 204 is fixedly installed on one side of the return spring 203. A limiting plate 205 is fixedly installed on one side of the connecting plate 204. The limiting plate 205 is adjustable in length and retraction at the bottom of the sealing cover body 100 via the return spring 203. A rotating plate 206 is movably connected to one side of the limiting plate 205. Bearings 2 are rotatably connected to both sides of the rotating plate 206. 07. The clamping plate 200 is fixedly clamped to one side of the surface of the bearing 207. The clamping plate 200 is adjusted by rotating the rotating plate 206 and the bearing 207 on the surface of the limiting plate 205 so that the clamping plate 200 is distributed vertically around the bottom of the clamping groove 102. A sealing rubber pad 201 is provided on one side of the surface of the clamping plate 200. A retaining ring 208 is fixedly installed on the upper surface of the clamping plate 200. The retaining ring 208 is evenly distributed at the center position above the clamping plate 200 and moves synchronously with the limiting plate 205 on the bottom surface of the sealing cover body 100 through the return spring 203.
[0037] The sealing cover body 100 has a slot 102 inside and through holes 101 around the top of the sealing cover body 100.
[0038] The card plate 200 is fan-shaped and evenly distributed around the bottom of the sealing cover body 100. It is installed around the surface of the card slot 102 by the rotating plate 206. The limiting plate 205 is U-shaped and has a sliding groove on its inner wall. The card plate 200 is adjusted by sliding on the surface of the sliding groove by the rotating plate 206.
[0039] It should be noted that: the through holes 101 on the top perimeter ensure gas exchange inside the mushroom stick and maintain the respiratory environment required for the growth of edible fungi. The grooves 202 on the bottom surface of the sealing cap body 100 are equipped with a return spring 203. One end of the spring is connected to the connecting plate 204, which in turn drives the extension and retraction of the limiting plate 205. The limiting plate 205 is U-shaped and has a sliding groove on its inner wall. The retaining plate 200 is movably connected to the limiting plate 205 through the rotating plate 206 and slides in the sliding groove. The two sides of the rotating plate 206 are rotatably connected to the retaining plate 200 through the bearings 207, so as to realize the rotation adjustment of the retaining plate 200 on the surface of the limiting plate 205, which is used to adjust the tightness of the sealing rubber gasket 201 and the retaining ring 208 with the edible fungi stick.
[0040] The sealing cap is aligned with the mushroom stick and placed down. The mushroom stick squeezes the clamping plate 200. The clamping plate 200 rotates on the surface of the limiting plate 205 via the rotating plate 206 and the bearing 207, and slides along the inner wall groove of the limiting plate 205 to adjust its position to fit the surface of the mushroom stick. During this process, the limiting plate 205 is squeezed and retracts into the groove 202 through the return spring 203 until the clamping plate 200 fits tightly against the mushroom stick, forming a seal.
[0041] During the growth of edible fungi, the sealing rubber pad 201 and the tightly fitted card plate 200 block external bacteria, dust and moisture, while the through hole 101 ensures gas exchange between the inside of the mushroom stick and the outside, meeting the respiratory needs of edible fungi growth.
[0042] Working principle: When sealing small edible mushroom logs, first align the sealing cap body 100 with the top of the log and begin lowering it. Upon contact with the log, the clamping plate 200 folds inward on the surface of the limiting plate 205, using the bearing 207 as an axis. As the sealing cap continues to lower, the head of the log is smoothly engaged into the groove 102 inside the sealing cap body 100.
[0043] At this point, the force applied to the sealing cap is released, and the clamping plate 200, using the bearing 207 as a pivot point, folds back to its original position. During this process, the return spring 203 within the groove 202 at the bottom of the sealing cap body 100 functions, continuously generating a pushing force on the limiting plate 205. Under this pushing force, the limiting plate 205 pushes the clamping plate 200 connected to it, causing the sealing rubber gasket 201 fixedly installed on one side of the clamping plate 200 to tightly adhere to the surface of the edible mushroom substrate. This not only prevents the intrusion of external impurities but also ensures the stability of the internal growth environment of the substrate.
[0044] Working principle: When facing a large edible mushroom log, the operator aligns the sealing cap body 100 with the top of the log and begins to lower it. At this time, the card plate 200 has not yet come into contact with the log, but as the sealing cap gradually approaches, it prepares for the subsequent sealing operation.
[0045] The clamping plate 200 and the limiting plate 205 are connected by a rotating plate 206 and a bearing 207. When the clamping plate 200 contacts the mushroom stick, it begins to fold and unfold with the bearing 207 as the axis. This design allows the clamping plate 200 to flexibly change its angle to adapt to the sealing requirements of mushroom sticks of different sizes.
[0046] The inner wall of the limiting plate 205 is provided with a sliding groove. After being folded and unfolded, the card plate 200 slides in the sliding groove with the help of the rotating plate 206 and extends outward around the bottom of the sealing cap body 100. Since the card plates 200 are evenly distributed around the bottom of the sealing cap body 100 at right angles, they can fully cover the outer periphery of the mushroom stick during the extension process, increasing the contact area with the mushroom stick.
[0047] The retaining ring 208 is originally laid flat on the upper surface of the retaining plate 200, parallel to the bottom of the sealing cap body 100. As the retaining plate 200 extends outward, the retaining ring 208 also moves and engages with the surface of the larger edible mushroom log. The surface of the retaining ring 208 is also provided with a sealing rubber gasket 201, which further enhances the sealing effect.
[0048] The return spring 203 within the groove 202 at the bottom of the sealing cap body 100 continuously exerts a pushing force on the limiting plate 205. Under the action of this pushing force, the limiting plate 205 pushes the connected clamping plate 200, causing the sealing rubber gasket 201 fixedly installed on one side of the clamping plate 200 to tightly adhere to the surface of the edible mushroom log. This process not only ensures close contact between the clamping plate 200 and the mushroom log, but also fills the tiny gaps between the clamping plate 200 and the surface of the mushroom log through the elastic deformation of the sealing rubber gasket 201, effectively preventing the intrusion of external bacteria, dust, and moisture.
[0049] After the above operations are completed, the clamping plate 200, the retaining ring 208, and the sealing rubber gasket 201 work together to form a stable seal for the larger edible mushroom logs. During the growth of the edible mushrooms, this continuously provides a relatively stable and clean growth environment for the logs, meeting the environmental requirements for mushroom growth.
