[0029] A scraping component 4 is provided in the middle position inside the support frame 1, and the scraping component 4 is used to scrape off the feed adhered to the inner wall of the weighing bucket 5 to avoid the feed adhered to the inner wall of the weighing bucket 5 not being cleaned in time, resulting in a decrease in weighing accuracy.

[0032] Embodiment Two:

[0033] Based on Embodiment One, in this embodiment, by starting the low-speed motor 41, the low-speed motor 41 can drive the rotating vertical rod 42 to rotate slowly. The rotating vertical rod 42 will带动 the scraping strip 43 to rotate together through the follower rod 44 to scrape off the feed adhered to the inner wall of the weighing hopper 5, thereby preventing the feed adhered to the inner wall of the weighing hopper 5 from not being cleaned in time and affecting the weighing accuracy.

[0034] The scraping component 4 includes a low-speed motor 41, a rotating vertical rod 42, a scraping strip 43, and a follower rod 44. The low-speed motor 41 is installed at the middle position of the upper end surface of the support frame 1. The low-speed motor 41 is connected to an external control panel through a wire. The low-speed motor 41 can drive the rotating vertical rod 42 to rotate slowly during operation. The rotating vertical rod 42 is installed at the lower end of the low-speed motor 41. The rotating vertical rod 42 can drive the follower rod 44 to rotate. The follower rod 44 is installed on the lower side of the circumferential side of the rotating vertical rod 42. The follower rod 44 and the scraping strip 43 are of an integral structure. The follower rod 44 can drive the scraping strip 43 to rotate. The scraping strip 43 is provided at the left end of the follower rod 44. The shape of the scraping strip 43 is a V shape. The scraping strip 43 is matched with the weighing hopper 5. The scraping strip 43 matched with the weighing hopper 5 can scrape off the feed adhered to the inner wall of the weighing hopper 5 when rotating. The follower rod 44 is connected and fixed to the rotating vertical rod 42 by a screw. The follower rod 44 connected and fixed to the rotating vertical rod 42 by a screw is convenient for later disassembly, so that the staff can replace the worn scraping strip 43.

[0035] Working principle: When it is necessary to scrape off the feed adhering to the inner wall of the weighing bucket 5, the staff only needs to start the low-speed motor 41, so that the low-speed motor 41 can drive the rotating vertical rod 42 to rotate at a low speed, and the rotating vertical rod 42 will drive the scraping bar 43 to rotate together through the follower rod 44, so that the low-speed rotating scraping bar 43 can scrape off the feed adhering to the inner wall of the weighing bucket 5. At the same time, starting the electric unloader 51 can discharge the feed scraped off from the inside of the weighing bucket 5 downward, thereby avoiding the feed adhering to the inner wall of the weighing bucket 5 not being cleaned in time and affecting the weighing accuracy. When the inner wall of the weighing bucket 5 is scraped clean, the staff can turn off the low-speed motor 41 to stop the scraping bar 43 from rotating, and then start the feeding auger 2 to transport the feed in the batching bin 3 to the weighing bucket 5. Weighing is performed inside; later, when it is necessary to calibrate the load cell 7, the staff first loosens the fixing screws 85 with a wrench. At this time, the hanging tube 82 can be moved up and down to adjust the height of the shelf frame 81. When the heights of the shelf frames 81 on the left and right sides and the front and back sides are adjusted to the same required height, the fixing screws 85 are tightened to prevent the hanging tube 82 from falling back. Then, four sets of calibration weights 84 of the same specification can be placed in the shelf frames 81 on the left and right sides and the front and back sides respectively, so that the staff can calibrate the load cell 7 with the help of the calibration weights 84 to ensure the subsequent weighing accuracy of the load cell 7. When the calibration is completed, only the four sets of calibration weights 84 need to be removed from the shelf frames 81 respectively.
