[0021] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0022] like Figure 1As shown, a weighing device that adapts to changes in material adjustment includes a weighing tank 1 and a screening assembly 5. A weighing module 3 is installed at the lower end of the weighing tank 1 through a support seat 2. The weighing module 3 directly weighs the amount of material in the weighing tank 1 and outputs the value through a controller. The weighing module 3 is connected to a control cabinet 4 through electric wires. There are four groups of weighing modules 3 and support seats 2. A hydraulic rod 6 is installed at the lower end of the lower support plate 505. The hydraulic rod 6 and the base 7 suspend the screening assembly 5 on the top of the weighing tank 1, so that the weighed material does not contain blocks or impurities, thereby increasing the accuracy of weighing, and the fixed end of the hydraulic rod 6 is installed with a base 7.

[0023] like Figure 2 As shown, a screening component 5 for adapting to materials in different states and screening out impurities is arranged inside the top of the weighing tank 1, and the screening component 5 includes a screening hopper 501, an outer rack 502, a limit block 503, a power tooth 504 and a lower support plate 505. The outer side of the screening hopper 501 is installed with an outer rack 502. The inverted cone-shaped screening hopper 501 can play a role in screening the material to be weighed. The screening hopper 501 is in the shape of an inverted cone. The screening hopper 501 can be used for screening when the material is in liquid, solid or powder state, and the larger particles in the material can be separated. The lumps or impurities are discharged, and the outer rack 502 and the power teeth 504 are symmetrically arranged in two groups about the center point of the screening hopper 501, and a limit block 503 is arranged at the end of the outer rack 502. The limit block 503 prevents the power teeth 504 from escaping from the outer rack 502 and plays a limiting role. The side of the outer rack 502 is meshed with power teeth 504. The servo motor drives the power teeth 504 to drive the screening hopper 501 at the end of the outer rack 502 to swing left and right, assisting the unloading of the screening hopper 501 to prevent blockage and accumulation, and a lower support plate 505 is installed at the lower end of the power teeth 504.

[0024] like Figure 3 As shown, the upper end of the weighing tank 1 is connected to an outer ring 8, and the upper end of the outer ring 8 is connected to a connecting ring 9. The outer ring 8 and the connecting ring 9 act as an external enclosure in the gap between the screening hopper 501 and the top of the weighing tank 1 to avoid serious dust during screening of materials. The outer ring 8 and the connecting ring 9 are an integrated structure, and the outer diameter of the connecting ring 9 is smaller than the outer diameter of the screening hopper 501. A movable groove 10 is provided on the inner wall of the connecting ring 9, and a sliding block 11 is installed inside the movable groove 10. The shape of the sliding block 11 is T-shaped, and the sliding block 11 can be aligned in the movable groove 10, and there are four sliding blocks 11 arranged in a ring about the center point of the movable groove 10.

[0025] In summary, the weighing device that adapts to material adjustment changes firstly Figure 1-Figure 3The structure shown in the figure, align the material feeding nozzle directly above the weighing tank 1, and discharge the material into the screening hopper 501 for screening processing to avoid the block or impurities in the material affecting the subsequent use after weighing. The screening hopper 501 can be used for screening processing when the material state is adjusted to discharge larger lumps or impurities in the material. When screening, the hydraulic rod 6 and the base 7 suspend the screening component 5 on the top of the weighing tank 1, so that the weighed material does not contain blocks or impurities, thereby increasing the accuracy of weighing. When screening, turn on the servo motor to drive the power gear 504 to drive the screening hopper 501 at the end of the outer rack 502 to swing left and right, assisting the discharge of the screening hopper 501 and preventing blockage and accumulation. The weighing module 3 directly outputs the material amount in the weighing tank 1 for personnel to check. When screening, the outer ring 8 and the connecting ring 9 act as an external enclosure in the gap between the screening hopper 501 and the top of the weighing tank 1. The connecting ring 9 is not connected to the screening hopper 501 to avoid serious dust during material screening.
