[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] like Figures 1-4 As shown, a liquid batching system includes a mixing tank 1 and multiple batching components 2. Each batching component 2 includes a liquid feeding hopper 3, a feeding pump 4, and a liquid weighing unit 5. The liquid weighing unit 5 includes a frame 51, a distributing hopper 52 disposed on the frame 51, a metering hopper 53 disposed on the frame 51 and located below the distributing hopper 52, a weighing platform 54 disposed on the frame 51 and located at the bottom of the metering hopper 53, a weighing sensor 55 disposed on the weighing platform 54, a flow valve 56 disposed between the distributing hopper 52 and the metering hopper 53, and a feeding pump 57 disposed between the metering hopper 53 and the mixing tank 1.

[0024] By adopting the above technical solution, the mixing tank 1 is used to mix multiple component liquids that are quantitatively delivered to the mixing tank 1 by the batching component 2. The quantity of multiple component liquids is determined by the quantity of the batching component 2. Specifically, the batching component 2 is provided with seven components, which can quantitatively deliver seven different component liquids to the mixing tank 1. In the batching assembly 2, the liquid to be batched is fed into the corresponding liquid feeding hopper 3. The feeding pump 4 is used to transport the liquid in the liquid feeding hopper 3 to the distribution hopper 52. When batching is required, the liquid in the distribution hopper 52 enters the metering hopper 53 through the flow valve 56. The required liquid mass is weighed and measured by the weighing platform 54, and the liquid mass is accurately controlled by the weighing sensor 55. The flow valve 56 is closed by the feedback signal from the weighing sensor 55, and the liquid is temporarily stored in the metering hopper 53. After the liquids in multiple batching assemblies 2 have been weighed and quantified, and the liquids of multiple components are temporarily stored in the corresponding metering hoppers 53, the different component liquids in multiple metering hoppers 53 are simultaneously or sequentially transported to the same mixing tank 1 by the feeding pump 57. The volume of the liquid feeding hopper 3 is larger than the volume of the distribution hopper 52, and the volume of the distribution hopper 52 is larger than the volume of the metering hopper 53. Specifically, the volume of the liquid feeding hopper 3 can be 100L, the distribution hopper 52 is 50L, and the metering hopper 53 is 30L. Because of the liquid weighing unit 5, compared to the traditional method of using a pump and flow meter, it provides more accurate control over the liquid quality. Furthermore, by changing the number of batching components 2 used, quantitative mixing of multiple liquid components can be achieved, making it highly practical.

[0025] The top of the distributing hopper 52 is provided with a first feed pipe 521, and the bottom of the distributing hopper 52 is provided with a first discharge pipe 522. The top of the metering hopper 53 is provided with a second feed pipe 531, and the bottom of the metering hopper 53 is provided with a second discharge pipe 532. A flow valve 56 is connected between the first discharge pipe 522 and the second feed pipe 531. By placing the flow valve 56 between the bottom of the distributing hopper 52 and the top of the metering hopper 53, the flow of all liquid flowing out of the distributing hopper 52 can be controlled.

[0026] Furthermore, the feed pump 57 is connected between the second discharge pipe 532 and the mixing tank 1. The feed pump 57 transports the liquid in the second discharge pipe 532 to the mixing tank 1 through the pipeline. The mixing tank 1 is configured as an open mixing tank 1. The second discharge pipe 532 is located at the bottom of the metering hopper 53. All the liquid in the metering hopper 53 can flow out from the second discharge pipe 532. The feed pump 57 can transport the quantitatively dispensed liquid in the metering hopper 53 to the mixing tank 1. The mixing tank 1 is configured as an open mixing tank 1, which facilitates the overall cleaning of the mixing tank 1 and also facilitates the accommodation of a larger volume mixing component 11. The mixing component 11 can be electric or manual, or it can be automatic and manual switching. This allows for more reasonable mixing of liquids with different components to achieve the ideal mixing purpose.

[0027] A drain pipe 533 is installed at the bottom of the metering hopper 53. This drain pipe 533 allows for the discharge of all liquid from the metering hopper 53. If a malfunction occurs during a temporary work stoppage and repairs are needed, the liquid temporarily stored in the metering hopper 53 may become unsuitable due to prolonged storage; in such cases, the liquid must be drained through the drain pipe 533. Furthermore, when cleaning the metering hopper 53 and the distribution hopper 52 is required, after emptying both hoppers, the cleaning solution is introduced into the distribution hopper 52 through the first feed pipe 521. The flow rate valve 56 controls the flow of the cleaning solution into the metering hopper 53. After cleaning the distribution hopper 52 and the metering hopper 53, the cleaning solution is discharged from both hoppers through the drain pipe 533.

[0028] Furthermore, a filter element 534 is installed inside the metering hopper 53, dividing the metering hopper 53 into an upper end 535 and a lower end 536. The second discharge pipe 532 and the drain pipe 533 are both connected to the lower end 536. The filter element 534 filters the liquid inside the metering hopper 53, effectively removing impurities. Specifically, the metering hopper 53 may include a removable cover, allowing for the replacement of the filter element 534. Connecting the second discharge pipe 532 and the drain pipe 533 to the lower end 536 enables the transport of the filtered liquid.

[0029] In addition, a first stirring motor 31 is provided on the liquid feeding hopper 3. The first stirring motor 31 is driven by a first stirring rod 32 that extends into the liquid feeding hopper 3. The first stirring motor 31 is specifically installed above the liquid feeding hopper 3, and the first stirring rod 32 is inserted into the liquid feeding hopper 3. This can stir the liquid in the liquid feeding hopper 3 to prevent the liquid from becoming viscous. A second stirring motor 523 is provided on the distributing hopper 52. The second stirring motor 523 is driven by a second stirring rod 524 that extends into the distributing hopper 52. The second stirring motor 523 is specifically installed above the distributing hopper 52, and the second stirring rod 524 is inserted into the distributing hopper 52. This can stir the liquid in the distributing hopper 52 to prevent the liquid from becoming viscous.

[0030] Furthermore, a roller 511 is provided at the bottom of the frame 51, and a support foot 512 is provided at the bottom of the frame 51. The roller 511 facilitates the overall position adjustment of the frame 51, allowing the frame 51 to be positioned in a suitable location on the field. After the frame 51 has been adjusted, the support foot 512 is lowered and supported on the field surface, thus ensuring the overall stable positioning of the frame 51.

[0031] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
