Description

Technical Field

[0001] The utility model relates to the technical field of metal detection, and particularly relates to a high-precision metal detector. Background Technique

[0002] A metal detector is a device used to detect and identify metal materials in objects. It works based on the principle of electromagnetic induction. By emitting an electromagnetic field and measuring the reflected signal, it detects the presence of metal objects. Metal detectors are widely used in industrial production to detect metal foreign objects in products to ensure product quality and the safety of the production line. The working principle of a metal detector is based on the interference effect of metal on the electromagnetic field. When a metal object enters the detection area of the metal detector, it changes the distribution of the electromagnetic field and causes changes in the detector. By analyzing and processing these changes, the metal detector can determine the position and nature of the metal object.

[0003] In the prior art, during the use of a high-precision metal detector, due to the long-term use of the conveyor belt surface, some dust and debris will adhere to it. If not cleaned, it may affect the detection accuracy of the metal detector. Currently, the conveyor mechanism of the metal detector is usually cleaned manually. During the cleaning process, the metal detector needs to stop working, which will reduce the working efficiency of the metal detector. Content of the Utility Model

[0004] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0005] A high-precision metal detector of the utility model includes a detection table, and an automatic cleaning mechanism is arranged at the front end of the detection table;

[0006] The automatic cleaning mechanism includes a U-shaped plate. The left and right sides in the middle of the U-shaped plate are both penetrated and slidably connected with lifting rods. A scraper is fixedly connected to the upper side between the lifting rods. A connecting plate is fixedly connected to the lower side of the front wall of the scraper. The left and right sides in the middle of the connecting plate are both penetrated and fixedly connected with extraction pipes. The extraction pipes are all penetrated and fixedly connected to the upper side in the middle of the front wall of the storage bucket. Booster pumps are arranged on the upper sides of the outer peripheries of the extraction pipes. Spray heads are arranged at the output ends of the extraction pipes. A bottom plate is fixedly connected to the bottom between the two groups of lifting rods. A cylinder is fixedly connected to the middle of the top wall of the bottom plate, and the output end of the cylinder is fixedly connected to the middle of the bottom wall of the U-shaped plate.

[0007] As a preferred technical solution of the utility model, insertion holes are arranged at the front and rear sides of the top of the left and right walls of the U-shaped plate, and insertion rods are penetrated and slidably connected inside the insertion holes.

[0008] As a preferred technical solution of the present utility model, the storage barrels are respectively fixedly connected to the left and right sides of the bottom wall of the U-shaped plate, and the bottom plate is located between the two groups of U-shaped plates.

[0015] 2. For this kind of high-precision metal detector, when the conveyor belt needs to be cleaned, start the air cylinder.
