Description

Technical Field

[0001] This utility model relates to a metal detection device, specifically an easy-to-install device for detecting heavy metal residues in edible fungi, belonging to the technical field of edible fungi detection equipment. Background Technology

[0002] Edible fungi refer to large fungi that can be consumed by humans. Common varieties include shiitake mushrooms, oyster mushrooms, enoki mushrooms, and king oyster mushrooms. They are rich in protein, dietary fiber, various vitamins, and minerals, making them a healthy food ingredient that combines nutrition and flavor, and are widely used in the food processing industry. Because the growth substrates of edible fungi (such as culture media and casing soil) are easily contaminated by heavy metals in the soil, and their mycelium has a strong ability to accumulate heavy metals, excessive heavy metal residues can harm human health. Therefore, it is necessary to test edible fungi products for heavy metal residues. Metal detectors, which use electromagnetic induction principles to quickly identify heavy metal substances contained in edible fungi and their packaging, are key equipment for rapid screening of heavy metal residues in edible fungi, effectively ensuring the safety of edible fungi products.

[0003] However, most existing metal detectors used for edible fungi testing are installed using bolts. They are usually directly fastened to the pre-installed mounting surface of key positions such as the conveyor belt frame in the edible fungi production line. During disassembly and assembly, not only do they require the use of professional tools such as wrenches and screwdrivers to loosen or tighten multiple bolts one by one, but the installation is also time-consuming. Utility Model Content

[0004] The purpose of this invention is to provide an easy-to-install heavy metal residue detection device for edible fungi in order to solve the above problems. The device uses a rotating shaft to drive the connecting column to rotate synchronously. The cam groove on the connecting column pushes the ball on the card plate, causing the card plate to be inserted into the card frame, thereby quickly completing the positioning and fixing of the metal detector and greatly shortening the installation time of the equipment on the production line.

[0018] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-4 As shown, an easy-to-install heavy metal residue detection device for edible fungi includes a conveyor 1, a mounting base 7 mounted on the conveyor 1, a metal detector 4 detachably connected to the mounting base 7, an alarm light 6 mounted on the conveyor 1, and the metal detector 4 mounted on the mounting base 7 via a mounting structure 2. The mounting structure 2 includes a frame 201, two frames 201 mounted on the metal detector 4, two guide rods 202 fixedly connected to the mounting base 7, and a locking plate 203 slidably connected to the guide rods 202. The two locking plates 203 respectively engage with the two frames 201. A rotating shaft 206 is rotatably connected to the mounting base 7, a connecting shaft 204 is rotatably connected to the locking plate 203, ball bearings 205 are fixedly connected to the connecting shaft 204, and two connecting posts 207 are fixedly connected to the rotating shaft 206. The connecting posts 207 are provided with cam grooves 208, and the two ball bearings 205 respectively roll into the two cam grooves 208.

[0020] As a technical optimization of this utility model, the rotating shaft 206 is fixed by the fixing structure 3. The fixing structure 3 includes a rotating rod 301. The rotating rod 301 is fixedly connected to the rotating shaft 206. A sliding column 302 is slidably connected to the rotating rod 301. The mounting base 7 is provided with two fixing holes 303. When the locking plate 203 is engaged, the sliding column 302 on the rotating rod 301 is released. The spring 305 will push the sliding column 302 into the fixing hole 303 of the mounting base 7 to lock the rotating shaft 206, preventing the metal detector 4 from loosening due to vibration during operation and improving the stability after installation. The two fixing holes 303 are symmetrically arranged about the center of the rotating shaft 206. The sliding column 302 engages with one of the fixing holes 303. A connecting ring 304 is fixedly connected to the sliding column 302. A spring 305 is fixedly connected between the connecting ring 304 and the rotating rod 301. The conveyor 1 is provided with a waste removal structure 5, which includes a driving component 501.

[0021] As a technical optimization of this utility model, a drive component 501 is installed on the conveyor 1. A push plate 502 is installed on the drive end of the drive component 501. Two guide shafts 504 are fixedly connected to the push plate 502. The two guide shafts 504 are symmetrically arranged about the center of the push plate 502. At the same time, the drive component 501 (preferably a hydraulic rod) is activated, and its drive end pushes the push plate 502 to move. The guide shafts 504 on the push plate 502 slide along the guide sleeve 503 on the conveyor 1, which ensures that the push plate 502... The pusher plate 502 pushes the waste material to the collection area next to the conveyor 1 with high accuracy and avoids deviation and jamming during the push process. At the same time, the baffle 506 can prevent the waste material from splashing, making the waste removal process efficient and orderly, which is suitable for the continuous production rhythm of edible fungi processing. Two guide sleeves 503 are fixedly connected to the conveyor 1, and two guide shafts 504 are slidably connected to the two guide sleeves 503 respectively. A fixed column 505 is fixedly connected to the conveyor 1, and a baffle 506 is fixedly connected to the fixed column 505.

[0022] In use, this invention is first connected to the front and rear sections of the edible fungus processing production line at the finished product conveying station to ensure stable and continuous transport of the edible fungus in the packaging bags. When the metal detector 4 needs to be installed, the sliding column 302 is pulled by the pull plate on the sliding column 302. The connecting ring 304 on the sliding column 302 will cause the spring 305 to contract, and at the same time, the sliding column 302 will disengage from the fixing hole 303. At this time, the rotating rod 301 can be rotated, and the rotating shaft 206 will drive the connecting column 207 to rotate synchronously. The cam groove 208 on the connecting column 207 will push the ball 205 on the clamping plate 203, causing the clamping plate 203 to slide along the guide rod 202 and be inserted into the clamping frame 201, thereby quickly completing the positioning and fixing of the metal detector 4 and greatly shortening the installation time of the equipment on the production line. After the clamping plate 203 is in place, the sliding column 302 on the rotating rod 301 is released, and the spring 305 will push the sliding column 302 to be inserted into the installation. The rotating shaft 206 is locked in the fixing hole 303 of the seat 7 to prevent the metal detector 4 from loosening due to vibration during operation, thus improving the stability after installation. When the edible fungi in the packaging bag are transported to the metal detector 4 by the conveyor 1 for heavy metal detection, if excessive waste is detected, the alarm light 6 connected to the metal detector 4 will light up and flash immediately to warn the on-site staff and make it easy for them to quickly know about the abnormal detection. At the same time, the drive component 501 (preferably a hydraulic rod) is started, and its drive end pushes the push plate 502 to move. The guide shaft 504 on the push plate 502 slides along the guide sleeve 503 on the conveyor 1, which not only ensures the pushing accuracy of the push plate 502, but also avoids deviation and jamming during the pushing process. Finally, the push plate 502 pushes the waste to the collection area next to the conveyor 1. At the same time, the baffle 506 can prevent waste from splashing, making the waste removal process efficient and orderly, and adapting to the continuous production rhythm of edible fungi processing.
