Description

Technical Field

[0001] This utility model relates to the field of sorting equipment technology, specifically to a vibrating screen for sorting dry bacteria. Background Technology

[0002] Dried mushrooms are products obtained by sun-drying, air-drying, or artificially drying freshly picked mushrooms. This allows mushroom products to be served on the table during the off-season and in areas where they do not grow, thus extending their shelf life and expanding their supply range.

[0003] To save space and reduce costs, especially for wild mushrooms, factories typically purchase dried mushrooms directly from farmers, either sun-dried or air-dried. After purchasing these dried mushrooms, the factory uses a vibrating screen to sort them, removing broken mushrooms and other impurities, before further processing and final packaging. Sometimes, these dried mushrooms contain impurities such as small iron wires and steel needles. Because these wires and needles are relatively thin and long, they may fail to pass through the screen and end up in the finished product. This not only seriously damages the company's image but could also cause injury to consumers due to accidental ingestion. Summary of the Invention

[0004] The purpose of this invention is to provide a vibrating screen for sorting dry bacteria, which can effectively trap magnetic impurities such as iron wires and steel needles mixed in with the dry bacteria, thus ensuring the product quality of the dry bacteria.

[0027] The following is in conjunction with the appendix Figure 1 ~Attached Figure 4 The embodiments of this utility model will be described in detail below.

[0028] This utility model provides a vibrating screen for sorting dry bacteria. The vibrating screen includes: a base 1, a screen box 2 mounted on the base 1, and a vibrating motor 3 for driving the screen box 2 to vibrate. A shock-absorbing spring 4 is provided between the base 1 and the screen box 2. The screen box 2 has at least one layer of screen mesh 5 to divide the material into multiple layers of channels. Each layer of material channel has a discharge port at its right end. The screen box 2 has a hopper 6 at its top left end. The bottom plate of the hopper 6 has a discharge port 14, and a magnet is provided at the discharge port 14. It should be understood that the magnet can be a permanent magnet or an electromagnet.

[0029] The specific implementation method of this utility model is described below: The vibration motor 3 is started, and the material is gradually fed into the hopper 6. When the material falls into the screen box 2 through the discharge port 14 of the hopper 6, magnetic impurities such as iron wires and steel needles mixed in the material are attracted by the magnet of the discharge port 14. Then, broken dried bacteria and other impurities pass through the screen 5 of the screen box 2, fall into the lower material channel, and are discharged from the discharge port of that material channel; intact dried bacteria remain in the upper material channel and are discharged from the discharge port of that material channel. This utility model can effectively trap magnetic impurities such as iron wires and steel needles mixed in with the dried bacteria, ensuring the product quality of the dried bacteria, and also has the advantages of simple structure and low cost.

[0030] Furthermore, the magnet is installed inside the sleeve 7; the hopper 6 is provided with a positioning ring 8 and a positioning plate 9; one end of the sleeve 7 is placed inside the positioning ring 8, and the other end is connected to the positioning plate 9 by bolts. It should be understood that the hopper 6 of the vibrating screen is relatively large, and the front-to-back length of the discharge port 14 is correspondingly long. Magnets are usually relatively short, and to ensure that the effective range of the magnets can cover the entire discharge port 14, multiple magnets are usually required; in this case, multiple magnets can be placed inside the sleeve 7, and then the sleeve 7 can be installed in the hopper 6; this makes assembly and disassembly more convenient. A threaded hole can be provided at the end of the sleeve 7, and a positioning hole can be provided in the positioning plate 9 to install bolts for connecting the two.

[0031] Furthermore, the sleeve 7 includes: a cylindrical body 10 with an open end, and a cylindrical cover 11 that closes the open end of the cylindrical body 10; the cylindrical cover 11 has a threaded head that is inserted into the open end, and the cylindrical body 10 has an internal thread in the open end that is adapted to the threaded head.

[0032] Furthermore, the hopper 6 is also equipped with an adjusting plate 12; the adjusting plate 12 is slidably connected to the bottom plate of the hopper 6 and is fitted with a locking member 13 to adjust the width of the discharge port 14. It should be understood that the width of the discharge port 14 is usually slightly larger than the size of the dried bacteria to ensure that the magnet can achieve the best effect. By adjusting the width of the discharge port 14, it can be used to sort different types and sizes of dried bacteria.

[0033] Furthermore, the adjusting plate 12 is provided with a strip-shaped hole 15 extending in the left-right direction; the locking member 13 includes: a screw portion passing through the strip-shaped hole 15 and a knob located at the top of the screw portion; the bottom plate of the hopper 6 is provided with an internally threaded cylinder 16 for installing the screw portion. It should be understood that by loosening the locking member 13, the adjusting plate 12 can be slid in the left-right direction to adjust the width of the discharge port 14. After adjustment, the locking member 13 can be tightened.

[0034] Furthermore, the locking member 13 has a locking spring 17 sleeved on the screw portion, and an annular washer 18 is provided at the bottom end of the locking spring 17. It should be understood that by providing the locking spring 17 and the annular washer 18, pressure can be applied to the adjusting plate 12 more evenly and stably, thereby ensuring the locking effect on the adjusting plate 12.

[0035] Furthermore, the positioning rings 8 and positioning pieces 9 are both located on the adjusting plate 12 of the hopper 6; the adjusting plate 12 has positioning rings 8 at the bottom of both the front and rear ends, and two positioning pieces 9 are correspondingly arranged in the middle; two sleeves 7 are provided accordingly. It should be understood that providing two sleeves 7 can reduce the length of a single sleeve 7, making disassembly and assembly less space-intensive and more convenient. The positioning rings 8 and positioning pieces 9 are located at the right end of the adjusting plate 12.

[0036] Furthermore, the internally threaded cylinder 16 extends downward from the upper surface of the bottom plate of the hopper 6. It should be understood that this ensures that the upper surface of the bottom plate of the hopper 6 is flush, thereby better aligning with the adjusting plate 12.

[0037] Although specific embodiments of the present invention have been described above, those skilled in the art should understand that various changes or modifications can be made to these embodiments without departing from the principles and essence of the present invention, but all such changes and modifications fall within the protection scope of the present invention.
