Description

Technical Field

[0001] This patent relates to the field of shiitake mushroom screening, specifically a screening device for removing impurities from dried shiitake mushrooms. Background Technology

[0002] Shiitake mushrooms are an edible fungus with a delicious taste and rich nutritional value. Shiitake mushrooms are umbrella-shaped, dark brown or dark brown in color, and vary in size. When processing shiitake mushrooms, they need to be screened, and a corresponding screening machine is required for this process.

[0003] In a mushroom screening machine proposed in CN222112479U, the mushrooms are fed into a screening drum and then screened according to their size through the screening holes on the screening drum.

[0004] However, the document mentioned above did not include a shielding structure inside the screening drum, which caused the shiitake mushrooms to easily roll from the higher side of the drum to the lower side during the screening process, resulting in incomplete screening and affecting the screening effect. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this patent is to provide a sieving device for removing impurities from dried shiitake mushrooms.

[0006] The technical solution adopted by this patent to solve its technical problem is: a sieving device for removing impurities from dried shiitake mushrooms, including a shell and a rotating screen cylinder. A support frame is installed on the inner side wall of the shell, and a rotating screen cylinder is rotatably installed on the inner side of the support frame. The rotating screen cylinder is inclined inside the shell.

[0007] A blocking mechanism is inserted and installed on the side wall of the casing. The blocking mechanism includes a guide cylinder, an electrically controlled push rod, and a baffle plate. The guide cylinder is inserted and installed on the side wall of the casing. The guide cylinder is inclined at the same angle as the rotating screen cylinder. An electrically controlled push rod is inserted and installed inside the guide cylinder. The electrically controlled push rod is electrically connected to an external power source. The output end of the electrically controlled push rod can be inserted into the rotating screen cylinder. A baffle plate is installed on the output end of the electrically controlled push rod. The outer side wall of the baffle plate is in contact with the inner side wall of the rotating screen cylinder.

[0008] Furthermore, the baffle plate includes a plate body, a placement groove, and a fan. The plate body is installed at the output end of the electrically controlled push rod. The side wall of the plate body is provided with a placement groove, and a fan is inserted and installed in the placement groove. The fan is electrically connected to an external power source.

[0009] Furthermore, a motor base is installed on the upper wall of the inner cavity of the casing, and a motor is installed on the lower wall of the motor base. The motor is electrically connected to an external power source. The tilt angle of the motor is consistent with the tilt angle of the rotating screen cylinder. A gear is installed at the output end of the motor, and a gear ring is installed on the outer side wall of the rotating screen cylinder. The gear and the gear ring are meshed together.

[0010] Furthermore, a baffle plate is installed on the lower wall of the inner cavity of the casing. There are two baffle plates in total. The upper walls of the two baffle plates are respectively attached to the lower walls of the two support frames. The two baffle plates divide the inner cavity of the casing into three chambers. The side wall of the casing is provided with a discharge port. There are three discharge ports in total. The three discharge ports are respectively opened in the three chambers.

[0011] Furthermore, a rubber ring is fitted to the outer wall of the plate, and the rubber ring can fit against the inner wall of the rotating screen cylinder.

[0012] Furthermore, the support frame includes a rod and a bearing. The bearing is installed on the outside of the rotating screen cylinder, one end of the rod is installed on the upper wall of the bearing, and the other end of the rod is installed on the upper wall of the inner cavity of the casing.

[0013] The beneficial effects of this patent are:

[0014] This device uses an electrically controlled push rod and a baffle plate inside its rotating screen cylinder. After the dried shiitake mushrooms enter the rotating screen cylinder, the baffle plate can block the dried shiitake mushrooms, thus prolonging the screening time and preventing incomplete screening.

[0015] In addition, a fan is installed on the baffle plate of this device. When the dried shiitake mushrooms are being sieved, the fan is activated to generate airflow. The airflow can separate some light impurities in the dried shiitake mushrooms, such as dust and debris, from the dried shiitake mushrooms. Attached Figure Description

[0020] The present patent is further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the patent. Furthermore, it should be understood that after reading the teachings of this patent, those skilled in the art can make various alterations or modifications to this patent, and these equivalent forms also fall within the scope defined by the appended claims.

[0021] See Figure 1 , Figure 2 , Figure 3 This is a schematic diagram of the structure of this patent. A sieving device for removing impurities from dried shiitake mushrooms includes a shell 1 and a rotating screen cylinder 2. A support frame 3 is installed on the inner side wall of the shell 1. The rotating screen cylinder 2 is rotatably installed on the inner side of the support frame 3. The rotating screen cylinder 2 is inclined inside the shell 1.

[0022] In this device, one side of the outer shell 1 is open, which makes it easy to put the dried shiitake mushrooms into the rotating screen cylinder 2. Then, by rotating the rotating screen cylinder 2, the dried shiitake mushrooms are sieved through the sieve holes on the top of the rotating screen cylinder 2. The inclined rotating screen cylinder 2 allows the dried shiitake mushrooms inside to roll to the lower side of the rotating screen cylinder 2.

[0023] In this article, the sieve holes on the rotating sieve cylinder 2 have three specifications. The sieve holes closest to the opening of the shell 1 are the smallest, and the sieve holes become larger as they move further into the shell 1. At the same time, the three specifications of sieve holes correspond to the three chambers separated by the baffle plate 9, so that the dried shiitake mushrooms can be sieved according to their size.

[0024] A blocking mechanism 4 is inserted and installed on the side wall of the housing 1. The blocking mechanism 4 includes a guide cylinder 41, an electrically controlled push rod 42, and a baffle plate 43. The guide cylinder 41 is inserted and installed on the side wall of the housing 1. The guide cylinder 41 is inclined at the same angle as the rotating screen cylinder 2. The electrically controlled push rod 42 is inserted and installed inside the guide cylinder 41. The electrically controlled push rod 42 is electrically connected to an external power source. The output end of the electrically controlled push rod 42 can be inserted into the rotating screen cylinder 2. The output end of the electrically controlled push rod 42 is equipped with a baffle plate 43. The outer side wall of the baffle plate 43 is in contact with the inner side wall of the rotating screen cylinder 2.

[0025] The blocking mechanism 4 can block the dried shiitake mushrooms inside the rotating screen cylinder 2, thereby increasing the sieving time of the dried shiitake mushrooms and avoiding the situation of incomplete sieving of dried shiitake mushrooms.

[0026] The electrically controlled push rod 42 used in this device is a multi-stage electrically controlled push rod. By controlling the extension and retraction of the electrically controlled push rod 42, the position of the baffle plate 43 can be adjusted, as shown in the attached figure. Figure 2As shown in the figure, the baffle plate 43 is located at the transition between two sizes of sieve holes. When dried shiitake mushrooms are put into the rotating sieve cylinder 2, the baffle plate 43 blocks the dried shiitake mushrooms, causing them to stop at the first size of sieve hole, so that the smaller dried shiitake mushrooms can be completely screened out. Then, the electric control push rod 42 is controlled to retract, so that the dried shiitake mushrooms enter the next size of sieve hole, and the medium-sized dried shiitake mushrooms are screened out. After all the dried shiitake mushrooms are screened out, the electric control push rod 42 retracts again, so that the remaining larger dried shiitake mushrooms are screened out.

[0027] The baffle plate 43 includes a plate body 431, a placement groove 432 and a blower 433. The plate body 431 is installed at the output end of the electric control push rod 42. The side wall of the plate body 431 is provided with a placement groove 432. The blower 433 is inserted and installed in the placement groove 432 and is electrically connected to an external power source.

[0028] The air force generated by the blower 433 can separate light impurities such as dust and debris from the dried shiitake mushrooms. Under the action of the air force, the light impurities are blown out of the rotating screen cylinder 2, while the heavier dried shiitake mushrooms will continue to roll under the drive of the rotating screen cylinder 2, thereby achieving the removal of impurities from the dried shiitake mushrooms.

[0029] A motor base 5 is installed on the upper wall of the inner cavity of the casing 1, and a motor 6 is installed on the lower wall of the motor base 5. The motor 6 is electrically connected to an external power source. The tilt angle of the motor 6 is the same as the tilt angle of the rotating screen cylinder 2. A gear 7 is installed at the output end of the motor 6. A toothed ring 8 is installed on the outer wall of the rotating screen cylinder 2. The gear 7 and the toothed ring 8 are meshed and connected.

[0030] By setting the motor 6, it can drive the rotating screen cylinder 2 to rotate through the meshing of the gear 7 and the gear ring 8, so that the dried shiitake mushrooms inside can roll back and forth, thereby improving the screening effect of the dried shiitake mushrooms.

[0031] The lower wall of the inner cavity of the casing 1 is equipped with a baffle plate 9. There are two baffle plates 9 in total. The upper walls of the two baffle plates 9 are respectively attached to the lower walls of the two support frames 3. The two baffle plates 9 divide the inner cavity of the casing 1 into three chambers. The side wall of the casing 1 is provided with a discharge port 10. There are three discharge ports 10 in total. The three discharge ports 10 are respectively opened in the three chambers.

[0032] The baffle plate 9 divides the inner cavity of the shell 1 into three chambers, which correspond to the three specifications of the sieve holes on the rotating sieve cylinder 2, so that the dried shiitake mushrooms can be sieved into three sizes: large, medium and small. The sieved dried shiitake mushrooms will then be discharged through the three discharge ports 10.

[0033] A rubber ring 11 is fitted to the outer wall of the plate 431, and the rubber ring 11 can fit into the inner wall of the rotating screen cylinder 2.

[0034] The support frame 3 includes a rod 31 and a bearing 32. The bearing 32 is installed on the outside of the rotating screen cylinder 2. One end of the rod 31 is installed on the upper wall of the bearing 32, and the other end of the rod 31 is installed on the upper wall of the inner cavity of the casing 1.

[0035] When this patent is working, dried shiitake mushrooms are put into the rotating screen cylinder 2, and then the rotating screen cylinder 2 is driven to rotate by the motor 6. The dried shiitake mushrooms are screened through the screen holes on the top of the rotating screen cylinder 2. The inclined rotating screen cylinder 2 allows the dried shiitake mushrooms inside to roll to the lower side of the rotating screen cylinder 2.

[0036] At the same time, the baffle plate 43 will block the dried shiitake mushrooms, keeping them at the first size of the sieve hole, so that the smaller dried shiitake mushrooms can be completely sieved out. Then, the electric control push rod 42 is controlled to retract, so that the dried shiitake mushrooms enter the next size of the sieve hole, and the medium-sized dried shiitake mushrooms are sieved out. After they are completely sieved out, the electric control push rod 42 retracts again, so that the remaining larger dried shiitake mushrooms are sieved out. Then the sieved dried shiitake mushrooms will be discharged through the three discharge ports 10 respectively.

[0037] During the screening process, the air force generated by the blower 433 can separate light impurities such as dust and debris from the dried shiitake mushrooms.

[0038] It will be apparent to those skilled in the art that this patent is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this patent. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this patent is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this patent. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0039] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
