[0019] In order to make the technical methods, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0020] like Figure 1-Figure 4The shown structure is a weighing bucket cleaning structure, comprising a conical barrel body 1, an upper cover 2 being threadedly mounted on the end with a larger opening of the conical barrel body 1, a weighing bucket discharge port 3 being fixedly mounted on the end with a smaller opening of the conical barrel body 1, a cylinder 4 being fixedly mounted on the middle part of the upper surface of the upper cover 2, the output end of the cylinder 4 passing through the barrel cover and extending into the interior thereof, and being slidably connected thereto, a flushing assembly 5 being fixedly connected to the lower surface of the output end of the cylinder 4, and a scraping assembly 6 being arranged below the flushing assembly 5.

[0021] Furthermore, the flushing assembly 5 includes a water tank 51 fixedly connected to the lower surface of the output end of the cylinder 4, and a plurality of fixedly connected high-pressure nozzles 52 are evenly distributed on the outer wall of the water tank 51. A retractable hose 53 is fixedly connected to one side of the upper surface of the water tank 51. The retractable hose 53 passes through the upper cover 2 and extends to the outside thereof at one end away from the water tank 51, and a water inlet connector 54 is fixedly connected to the outer part. When it is necessary to flush the inner wall of the conical barrel body 1, first connect the water inlet connector 54 to clean water (or detergent), and the clean water is sprayed out from the high-pressure nozzle 52 after passing through the retractable hose 53 and the water tank 51. Then, the cylinder 4 is turned on, and the output end of the cylinder 4 drives the flushing assembly 5 and the scraping assembly 6 to move toward the discharge port 3. The sewage is discharged through the discharge port 3, thereby completing the overall flushing of the inner wall of the conical barrel body 1. After the flushing is completed, the cylinder 4 drives the flushing assembly 5 to reset.

[0022] Furthermore, the scraping assembly 6 includes a motor 61 fixedly connected to the lower surface of the water tank 51, a first rectangular rod 62 is fixedly installed on the output end of the motor 61, and a second rectangular rod 63 is slidably connected on both sides of the first rectangular rod 62, a first spring 64 is fixedly connected between the two side walls of the second rectangular rod 63, a telescopic rod 65 is slidably connected to the side wall of the second rectangular rod 63, a second spring 66 is fixedly connected between the side wall of the telescopic rod 65 and the inner cavity of the second rectangular rod 63, and a scraper 67 is detachably installed on the end of the telescopic rod 65 away from the second spring 66. After the inner wall of the conical barrel body 1 is flushed, the cylinder 4 and the motor 61 are turned on, and the cylinder 4 drives the flushing assembly Component 5 and scraping assembly 6 move toward the discharge port 3, and the output end of the motor 61 drives the first rectangular rod 62, the second rectangular rod 63, the telescopic rod 65 and the scraper 67 to rotate. During the rotation of the scraper 67, the water stains remaining on the barrel wall are scraped off, and the water stains are discharged from the discharge port 3 along the barrel wall. Since the conical barrel body 1 gradually shrinks toward one end of the discharge port 3, when the scraper 67 moves, the telescopic rod 65 compresses the second spring 66 and shrinks inward. As the scraper 67 continues to move, the two second rectangular rods 63 squeeze the first spring 64 inward and shrink inward. Under the action of the elastic force of the first spring 64 and the second spring 66, the scraper 67 is always in close contact with the barrel wall, thereby improving the effect of scraping off water stains.

[0023] Furthermore, the scraper 67 is tilted at one end away from the telescopic rod 65, which facilitates the scraper 67 to fit better with the barrel wall, further improving the effect of scraping water stains, and the scraper 67 is made of rubber to reduce wear on the barrel wall.

[0024] Furthermore, a sensor connecting structure 11 for connecting to a weighing sensor is fixedly installed on the outer circumferential wall of the upper side of the conical barrel body 1, and a weighing sensor is installed on the sensor connecting structure 11. The upper cover 2 is located on one side of the cylinder 4 and is fixedly installed with a weighing hopper feed port 21. When the material is weighed and packaged, the material is first added to the inside of the conical barrel body 1 through the feed port 21, and the material is discharged from the discharge port 3. The weighing sensor detects that the weight of the conical barrel body 1 decreases. When the designed discharge value is reached, the valve of the discharge port 3 is closed.
