Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this patent.

[0029] This specific embodiment provides a feed weighing device, such as Figures 1-8 As shown, it includes a frame 1, which is composed of two long cross beams and multiple supporting cross beams and longitudinal beams welded to each other. A bracket 2 is provided on the frame 1, and the bracket 2 is composed of two inclined longitudinal beams. The bottom of the bracket 2 is connected to the two long cross beams of the frame 1 by welding, and a hopper 3 is installed on the end of the bracket 2 by welding. The hopper 3 is a trapezoidal structure, and a feed port 17 is provided on the hopper 3. A first baffle 18 is installed above the feed port 17 to prevent material from scattering and overflowing. The first baffle 18 is a square structure and the side is open. Hooks 19 arranged along the Y-axis direction are evenly arranged at the side opening of the first baffle 18. The first baffle 18 is provided with a second opening 20 arranged along the Y-axis direction on the side away from the hook 19. There are at least two hooks 19 and the second opening 20, and the height positions of the hooks 19 and the second opening 20 correspond.

[0030] A detachable screen 4 is provided in the baffle, and the screen 4 is arranged above the feed port 17. Horizontally arranged connecting rods 21 are provided on both sides of the screen 4, and handles 22 are installed on the two connecting rods 21. The screen 4 is respectively provided with a first protrusion 23 and a second protrusion 24 on both sides away from the connecting rod 21. The first protrusion 23 is placed in the second opening 20, and the second protrusion 24 is placed on the top of the hopper 3. The connecting rod 21 is engaged with the hook 19. The above structure is used to fix the screen 4. The staff can adjust the height of the screen 4 by placing the connecting rod 21 in hooks 19 of different heights and placing the first protrusion 23 in the second opening 20 corresponding to the height of the hook 19.

[0031] The bottom of the hopper 3 is connected to a barrel 5, and a discharge port 6 is provided at the bottom of the barrel 5. The barrel 5 is a square structure, and an air hole 7 and a first opening 8 are provided on the side of the barrel 5. The first opening 8 is placed below the air hole 7; the air hole 7 is used to reduce the phenomenon of material blockage when the staff pours the material into the hopper 3, so that the feeding process is smoother; the air hole 7 is a circular structure, and there are three air holes 7 distributed in a triangular shape. A circular plate 25 for controlling the opening and closing of the air hole 7 is provided on the air hole 7, and a third opening is provided on the circular plate 25 at a position corresponding to the air hole 7. 26, the third opening 26 is a circular structure and the inner diameter is equal to the inner diameter of the air hole 7. A circular hole 27 is opened at the center of the circular plate 25. A pin 28 is rotatably installed in the circular hole 27. The end of the pin 28 is fixedly connected to the barrel 5. The circular plate 25 can rotate on the pin 28 to control the opening and closing of the air hole 7. When the staff rotates the circular plate 25 so that the position of the air hole 7 overlaps with the position of the third opening 26, the air hole 7 is in an open state. When the staff rotates the circular plate 25 so that the position of the air hole 7 and the third opening 26 are completely staggered, the air hole 7 is in a closed state.

[0032] A pull-out material receiving box 29 is provided in the first opening 8. The material receiving box 29 can not only be used to prevent the material from overflowing from the air hole 7 during feeding and then scattering onto the weighing equipment, affecting the accuracy of the weighing results, but can also be used to block the discharge port 6 of the barrel 5, so that the staff can stop conveying materials to the weighing equipment at any time; the bottom of the barrel 5 is provided with a second baffle 30 for preventing material and dust from splashing.

[0033] The two ends of the frame 1 are respectively connected to a driving roller 9 and a driven roller 10 through bearings, and a roller 13 and a weighing roller 14 that are rotatably connected to the frame 1 through bearings are arranged between the driving roller 9 and the driven roller 10; at least two rollers 13 are provided, and the weighing roller 14 is arranged between the two rollers 13 on the side close to the hopper 3.

[0034] The end of the active roller 9 is rotatably connected to the reduction motor 11 through a bearing, and the active roller 9 and the driven roller 10 are fixedly mounted with a support plate 31, and the support plate 31 is annularly arranged with a support rod 32 for supporting the skirt conveyor belt 16, and the support plate 31 is provided with four, and the support rod 32 is provided with at least two; the skirt conveyor belt 16 is rotatably connected to the support rod 32, and the support plate 31 and the support rod 32 support the skirt conveyor belt 16, and the roller 13 and the weighing roller 14 are rotatably connected to the skirt conveyor belt 16. When the staff starts the reduction motor 11, the reduction motor 11 drives the active roller 9 to rotate, so that the support plate 31 and the support rod 32 fixedly connected to the active roller 9 and the driven roller 10 rotate, thereby rotating the skirt conveyor belt 16, and then causing the driven roller 10, the roller 13 and the weighing roller 14 to rotate following the skirt conveyor belt 16, thereby realizing the skirt conveyor belt 16 to transport materials.

[0035] The end of the driven roller 10 is connected to a speed sensor 12 for measuring the transmission speed of the skirt conveyor belt 16. The speed sensor 12 can convert the speed signal of the skirt conveyor belt 16 into an electrical signal and output it to the control end; both ends of the weighing roller 14 are connected to a weighing sensor 15, and a support 33 for placing the weighing sensor 15 is provided under the weighing sensor 15. The two ends of the support 33 are fixedly connected to the frame 1, and the frame 1 is provided with a junction box 34 electrically connected to the reduction motor 11, the speed sensor 12, and the weighing sensor 15.

[0036] The weighing sensor 15 is used to monitor the weight of the material passing through the weighing roller 14 and convert the weight signal into an electrical signal and output it to the control end. The control end processes the received signal to complete the accurate measurement of the material weight.

[0037] The working principle of this utility model is:

[0038] First, the operator rotates the circular plate 25 so that the third opening 26 on the circular plate 25 overlaps the position of the air hole 7. This opens the air hole 7 and makes the feeding process smoother. Then, the operator pulls out the material receiving box 29 from the first opening 8, thereby opening the discharge port 6 and preventing the material from overflowing from the air hole 7 and scattering onto the skirt conveyor 16 during feeding, which would affect the weighing results.

[0039] Secondly, the staff pours the material into the hopper 3 from the feed port 17, and then screens the material through the screen 4 to make the material particles more uniform. The material with uniform particles enters the barrel 5 from the hopper 3, and then falls onto the skirt conveyor belt 16 from the discharge port 6. The reduction motor 11 drives the active roller 9 to rotate, so that the support plate 31 and the support rod 32 fixedly connected to the active roller 9 and the driven roller 10 rotate, thereby rotating the skirt conveyor belt 16, and then the driven roller 10, the roller 13 and the weighing roller 14 rotate with the skirt conveyor belt 16, thereby realizing the transportation of the material; when the material is transported to the weighing roller 14, the weighing sensors 15 at both ends of the weighing roller 14 measure and record the weight of the material, and convert the weight signal into an electrical signal and transmit it to the control end. At the same time, the speed sensor 12 on the driven roller 10 measures and records the transmission speed of the skirt conveyor belt 16, and converts the speed signal into an electrical signal and transmits it to the control end. The control end processes the received signal to complete the weighing of the material.

[0040] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
