Description

Technical Field

[0001] This utility model relates to the field of black fungus production equipment, and in particular to a screening device for removing impurities in black fungus production. Background Technology

[0002] In the production process of black fungus, after harvesting, black fungus needs to undergo a series of processing procedures, including the removal of impurities. Since black fungus is often accompanied by dirt, bark, branches and leaves during its growth, these impurities not only affect the appearance quality of the black fungus, but may also have a certain impact on its food safety. Therefore, how to efficiently and accurately remove these impurities has become a key issue in black fungus production. To this end, a screening device for removing impurities in black fungus production is proposed.

[0003] When screening wood ear mushrooms, existing screening devices cause some dust to be dispersed during the shaking process because the mushrooms are relatively dry. If workers inhale the dusty air for a long time, it can damage their respiratory tract. In addition, most existing screening devices cannot effectively change the mesh size of the screen, thus failing to effectively screen wood ear mushrooms of different qualities and sizes.

[0004] Therefore, in order to solve the problems existing in the above-mentioned technologies, a screening device for removing impurities in the production of black fungus is proposed. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a screening device for removing impurities in the production of black fungus. This device utilizes a dustproof component. A dustproof cover is placed on top of the screening frame, and a dust collection bag is secured with hooks. An electric motor is then activated, causing the paddles to rotate and generate suction. This suction force draws in the dust generated during screening, thus preventing dust from scattering and causing harm to workers.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A screening device for removing impurities in the production of wood ear mushrooms includes a support frame. A sieve frame is provided at the upper end of the support frame. A screen assembly is provided inside the sieve frame. The screen assembly includes sliding grooves opened on the inner walls of both sides of the sieve frame. The screen frame slides inside the sliding grooves. A wire mesh is fixedly connected to the inner wall of the screen frame. Two receiving grooves are opened at the front end of the upper surface of the screen frame. A damping rod is fixedly connected to the inner bottom surface of each receiving groove. A damping spring is sleeved on the rod body of the damping rod. A locking post is fixedly connected to the output end of the damping rod.

[0008] The upper end of the screening frame is provided with a dustproof component, which includes a dustproof cover. A dust inlet groove is opened in the middle of the top surface of the dustproof cover. A dust suction frame is fixedly connected to the middle of the upper surface of the dustproof cover. A bracket is fixedly connected to the inner wall of the dust suction frame. An electric motor is fixedly connected to the inner wall of the bracket. A paddle is fixedly connected to the output end of the electric motor. A drive motor is fixedly connected to the front end of the outer wall of one side of the support frame. Crankshaft wheels are provided at the front ends of the inner walls on both sides of the support frame.

[0009] The above technical solution allows for quick and easy replacement of the mesh size of the screen through the screen assembly, facilitating the screening and impurity removal of wood ear mushrooms of different qualities and sizes. Furthermore, the dustproof component effectively prevents dust from drifting out from the top of the screen frame and causing injury to the workers.

[0010] Furthermore, movable grooves are provided at the rear ends of the inner walls on both sides of the supporting frame, and movable columns are rotatably connected to the rear ends of the outer walls on both sides of the screening frame. The movable columns slide inside the movable grooves. The output end of the drive motor is fixedly connected to the center of the wheel body of one side crankshaft wheel, and the other side crankshaft wheel is rotatably connected to the inner wall on the other side of the supporting frame. The front end of the crankshaft wheel near the outer wall on the side of the screening frame is rotatably connected to the outer walls on both sides of the screening frame.

[0011] The above technical solution allows the crankshaft wheel to rotate via a drive motor, which in turn drives the sieve frame to perform reciprocating screening. This not only removes impurities from the wood ear mushrooms but also moves them out of the sieve frame.

[0012] Furthermore, a handle is fixedly connected to the front outer wall of the screen frame;

[0013] With the above technical solution, the screen frame can be moved out of the sliding groove more easily by pressing the locking pin through the handle.

[0014] Furthermore, multiple placement slots are provided on both sides of the upper surface of the sieve frame, and multiple placement blocks are fixedly connected to the edge of the lower surface of the dust cover. The outer wall of each placement block is tightly fitted to the inner wall of the placement slot.

[0015] The above technical solution allows for a more convenient and stable placement of the dust cover on the upper part of the sieve frame via the placement slots and blocks.

[0016] Furthermore, support handles are fixedly connected to the front and rear ends of the upper surface of the dust cover;

[0017] The above technical solution allows for easier removal of the dust cover via a support handle.

[0018] Furthermore, multiple hooks are fixedly connected to both outer walls of the dust collection frame, and a fabric air guide bag is fixedly connected to the upper surface of the dust collection frame.

[0019] The above technical solution allows for easier fixing of industrial dust collection bags via hooks, and the fabric air guide bag facilitates the guidance of dust generated during dust removal into the interior of the industrial dust collection bag.

[0020] Furthermore, a material collection frame is fixedly connected to the middle of the outer wall at the rear end of the screening frame;

[0021] The above technical solution allows for better centralized outflow of the cleaned wood ear mushrooms through the set collection frame.

[0022] Furthermore, support seats are fixedly connected to the four corners of the lower surface of the supporting frame;

[0023] The above technical solution allows the support base to better support the frame.

[0024] This utility model has the following beneficial effects:

[0025] 1. This utility model proposes a screening device for removing impurities in the production of wood ear fungus. Through a screen assembly, a steel wire screen with an appropriate aperture is rotated according to the quality and size of the wood ear fungus. The screen frame is then slid into a sliding groove, and a locking pin is pressed during sliding. Once the entire screen frame is inside the sliding groove, the locking pin engages with the holes in the sieve frame, thus fixing the screen frame in place. This allows for quick installation and replacement of steel wire screens with different apertures, enabling the screening device to effectively remove impurities from wood ear fungus of different qualities and sizes.

[0026] 2. The present invention proposes a screening device for removing impurities in the production of black fungus. By setting up a dustproof component, the dustproof cover is placed on the upper end of the screening frame, and then the dust collection bag is fixed by a hook. Then, the electric motor is started, which drives the paddle to rotate, thereby generating suction force to suck in the dust generated during screening. This avoids the problem of dust spreading everywhere during screening and causing harm to the workers. Attached Figure Description

[0039] One embodiment provided by this utility model:

[0040] Reference Figure 1 , Figure 4 and Figure 5 :

[0041] A screening device for removing impurities in the production of wood ear fungus includes a support frame 1. A sieve frame 3 is provided at the upper end of the support frame 1.

A screen frame 401 slides inside the sliding grooves 407. A wire mesh 402 is fixedly connected to the inner wall of the screen frame 401. Two receiving grooves 404 are opened at the front end of the upper surface of the screen frame 401. A damping rod 405 is fixedly connected to the inner bottom surface of each receiving groove 404. A damping spring 406 is sleeved on the rod body of the damping rod 405. A locking post 403 is fixedly connected to the output end of the damping rod 405.

[0042] The upper end of the screening frame 3 is provided with a dustproof component 5, which includes a dustproof cover 501.

[0043] The screen assembly 4 allows for quick and easy replacement of the screen aperture, facilitating the screening and impurity removal of wood ear mushrooms of different qualities and sizes. Furthermore, the dustproof assembly 5 effectively prevents dust from drifting out from the top of the screen frame 401 and causing injury to the workers.

[0044] Reference Figure 2 and Figure 5 :

[0045] Movable grooves 8 are provided at the rear ends of the inner walls on both sides of the supporting frame 1. Movable columns 9 are rotatably connected to the rear ends of the outer walls on both sides of the screening frame 3. The movable columns 9 slide inside the movable grooves 8. The output end of the drive motor 6 is fixedly connected to the center of the wheel body of one side crankshaft wheel 11.

The front end of the crankshaft wheel 11 near the outer wall of the screening frame 3 is rotatably connected to the outer walls on both sides of the screening frame 3. Thus, the drive motor 6 drives the crankshaft wheel 11 to rotate, which can more easily drive the screening frame 3 to perform reciprocating screening action. This allows the wood ear fungus to be screened and impurities removed while also moving the wood ear fungus so that it flows out of the screen frame 401.

[0046] Reference Figure 2 , Figure 5 and Figure 6 :

[0047] A handle 12 is fixedly connected to the front outer wall of the screen frame 401. By pressing the locking post 403 through the handle 12, the screen frame 401 can be moved out of the sliding groove 407 more easily.

[0048] Reference Figure 2 , Figure 3 and Figure 4 :

[0049] Multiple placement slots 10 are provided on both sides of the upper surface of the screening frame 3. Multiple placement blocks 503 are fixedly connected to the lower surface of the dust cover 501. The outer walls of the placement blocks 503 are tightly fitted to the inner walls of the placement slots 10. The placement slots 10 and placement blocks 503 make it easier to stably place the dust cover 501 on the upper end of the screening frame 3. The front and rear ends of the upper surface of the dust cover 501 are fixedly connected to the support handles 506. The support handles 506 make it easier to remove the dust cover 501.

The fabric air guide bag 505 makes it easier to guide the dust generated during the cleaning process into the interior of the industrial dust collection bag.

[0050] Reference Figure 5 :

[0051] A material collection frame 7 is fixedly connected to the middle of the outer wall of the rear end of the screening frame 3. The material collection frame 7 can better concentrate the flow of the wood ear fungus after the impurity removal process. Support seats 2 are fixedly connected to the four corners of the lower surface of the support frame 1. The support seats 2 can better support the support frame 1.

[0052] Working principle: During use, the operator rotates the wire mesh 402 with the appropriate aperture as needed, then slides the screen frame 401 into the sliding groove 407. While sliding, the operator manually presses the locking pin 403, compressing the damping rod 405 and damping spring 406, causing the locking pin 403 to enter the receiving groove 404. When the screen frame 401 is fully inside the sliding groove 407, the locking pin 403 is released, allowing it to be engaged in the holes of the sieve frame 3 by the elastic force of the damping rod 405 and damping spring 406, thus fixing the position of the screen frame 401. Then, an appropriate amount of dried wood ear mushrooms is placed in, and finally, the dust cover 501 is applied. The upper end of the screening frame 3 is then fixed to the dust collection frame 504 via hooks 502. The outlet of the fabric air guide bag 505 is then placed inside the industrial dust collection bag. The drive motor 6 is then started, causing the crankshaft wheel 11 to rotate. Through the eccentric action, the screening frame 3 is shaken, and the debris falls through the aperture of the wire mesh 402, thus removing impurities from the dried wood ear fungus inside. During drying, the electric motor 509 is started, causing the paddle 510 to rotate at high speed, thereby generating suction and sucking the dust generated during screening into the dust collection bag.

[0053] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
