Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-7 This utility model provides a technical solution: A raw material proportioning device for producing coated sand includes a mixing tank 1, a raw material tank 2 above the mixing tank 1, a conveying pipe 3 fixedly connected to the bottom of the raw material tank 2, a discharge pipe 4 fixedly connected to the end of the conveying pipe 3, the bottom end of the discharge pipe 4 fixedly connected to the top of the mixing tank 1, a conveying motor 5 fixedly installed at the end of the conveying pipe 3 away from the discharge pipe 4, a spiral blade 6 rotatably arranged inside the discharge pipe 4, the output shaft end of the conveying motor 5 fixedly installed to the rotating shaft end of the spiral blade 6, a sleeve 7 fixedly connected to the side of the discharge pipe 4, a spring 8 arranged inside the sleeve 7, a movable rod 9 slidably arranged on the sleeve 7, the spring 8 pressing between the sleeve 7 and the movable rod 9, a sealing plate 10 fixedly installed at the end of the movable rod 9, the sealing plate 10 facing the opening of the conveying pipe 3, and the size of the sealing plate 10 matching the size of the opening of the conveying pipe 3, and a raw liquid pipe 1 fixedly connected to the top of the mixing tank 1. 1. A valve 12 is provided at the bottom end of the raw liquid pipe 11, a vertical rod 13 is slidably provided at the top of the raw liquid pipe 11, a piston 14 is slidably provided inside the raw liquid pipe 11, the bottom end of the vertical rod 13 is fixedly installed with the piston 14, an electric telescopic rod 15 is fixedly installed at the top of the mixing box 1, a connecting plate 16 is fixedly installed at the end of the output shaft of the electric telescopic rod 15, and the top end of the vertical rod 13 is fixedly installed with the connecting plate 16. Both the raw material box 2 and the raw liquid pipe 11 are made of transparent material, and both the raw material box 2 and the raw liquid pipe 11 have scales on their sides. A stirring component 17 is provided on the mixing box 1. The stirring component 17 includes a stirring motor 171 fixedly installed at the top of the mixing box 1, a rotating rod 172 rotatably installed in the middle of the mixing box 1, and stirring rods 173 evenly distributed and symmetrically installed on the rotating rod 172. The end of the output shaft of the stirring motor 171 is fixedly installed with the end of the rotating shaft of the stirring rod 173.

[0022] In use, the mixing tank 1 is used to store the solid raw material of the coated sand, and the raw liquid pipe 11 is used to store the liquid raw material of the coated sand. When feeding solid raw materials, the conveyor motor 5 at the end of the conveyor pipe 3 is started. The output shaft of the conveyor motor 5 rotates. Since the output shaft of the conveyor motor 5 is fixedly installed with the rotating shaft of the spiral blade 6, it will drive the spiral blade 6, which is rotated inside the discharge pipe 4, to rotate synchronously. At this time, the solid raw materials in the raw material box 2 fall into the discharge pipe 4 through the conveyor pipe 3 fixedly connected to the bottom of the raw material box 2. The rotating spiral blade 6 conveys the solid raw materials forward, pushing the solid raw materials to move towards the discharge pipe 4, pushing open the sealing plate 10 at the opening of the conveyor pipe 3. When the solid raw materials reach the discharge pipe 4, the discharge pipe 4 is opened. After pipe 4, it automatically falls into mixing box 1. During the conveying process, spring 8 installed in sleeve 7 presses between sleeve 7 and movable rod 9, so that sealing plate 10 fixedly installed at the end of movable rod 9 is always facing the opening of conveying pipe 3. Since the size of sealing plate 10 is adapted to the size of the opening of conveying pipe 3, it can prevent the raw material from leaking when not conveying. When it is necessary to stop the solid raw material conveying, stop conveying motor 5, the spiral blade 6 stops rotating, and the solid raw material no longer conveys forward. Observe the scale on the side of raw material box 2 to achieve accurate quantitative feeding of solid raw material. When feeding liquid raw materials, start the electric telescopic rod 15. The output shaft of the electric telescopic rod 15 drives the connecting plate 16 to move downward. The connecting plate 16 drives the vertical rod 13 to move downward. The vertical rod 13 drives the piston 14 to slide downward in the raw liquid pipe 11. Under the pressure of the piston 14, the liquid raw materials in the raw liquid pipe 11 push open the valve 12 at the bottom and flow into the mixing box 1. By observing the scale and controlling the extension and retraction length of the electric telescopic rod 15, the feeding amount of liquid raw materials can be precisely controlled. After the solid and liquid raw materials of the coated sand are fully proportioned and fed, the stirring motor 171 at the top of the mixing tank 1 is started, which drives the rotating rod 172 to rotate. The stirring rod 173 on the rotating rod 172 stirs and mixes the solid and liquid raw materials that enter the mixing tank 1. This raw material proportioning device for coated sand production can accurately proportion and mix solid and liquid raw materials separately, ensuring the consistency of coated sand quality and making it highly practical.

[0023] At least two sets of raw material tank 2 and raw liquid pipe 11 are provided; The raw material tank 2 and the raw liquid pipe 11 are provided in at least two sets, which can store, mix and feed a variety of solid and liquid raw materials.

[0024] The top of each raw material box 2 is threaded with a sealing cap 18; When not in use, the sealing cap 18 is threaded onto the top of the raw material box 2 to prevent external dust, moisture, etc. from entering the raw material box 2, avoid the raw materials from getting damp and deteriorating, ensure the quality of the raw materials, and ensure that the raw materials can play a normal role in subsequent use and meet the requirements of coated sand production.

[0025] A movable sleeve 19 is slidably provided on the outer wall of the original liquid tube 11, and a connecting rod 20 is fixedly installed on the connecting plate 16, with the bottom end of the connecting rod 20 fixedly installed with the movable sleeve 19; When the electric telescopic rod 15 drives the connecting plate 16 to rise and fall vertically, the connecting rod 20 on the connecting plate 16 will drive the movable sleeve 19 to rise and fall vertically on the raw liquid pipe 11 in sync. During the sliding process of the movable sleeve 19 on the outer wall of the raw liquid pipe 11, it can clean the stains that may be attached to the outer wall of the raw liquid pipe 11, prevent the residual liquid from drying on the outer wall of the raw liquid pipe 11, and affect the observation of the scale on the raw liquid pipe 11. This ensures that the operator can clearly and accurately read the remaining amount of liquid raw material in the raw liquid pipe 11, thereby better controlling the ratio of liquid raw material.

[0026] The inner wall of the movable sleeve 19 is equipped with a rubber ring; Because the inner wall of the movable sleeve 19 is equipped with a rubber ring, when the movable sleeve 19 slides on the outer wall of the raw liquid tube 11, the rubber ring fits tightly against the outer wall of the raw liquid tube 11. By utilizing the elasticity and friction of the rubber ring, the residual liquid raw materials or stains attached to the outer wall of the raw liquid tube 11 can be removed more effectively, thereby improving the cleaning effect on the outer wall of the raw liquid tube 11 and providing a guarantee for the precise control of the liquid raw material ratio.

[0027] Working principle: In use, the mixing tank 1 is used to store the solid raw material of the coated sand, and the raw liquid pipe 11 is used to store the liquid raw material of the coated sand. When feeding solid raw materials, the conveyor motor 5 at the end of the conveyor pipe 3 is started. The output shaft of the conveyor motor 5 rotates. Since the output shaft of the conveyor motor 5 is fixedly installed with the rotating shaft of the spiral blade 6, it will drive the spiral blade 6, which is rotated inside the discharge pipe 4, to rotate synchronously. At this time, the solid raw materials in the raw material box 2 fall into the discharge pipe 4 through the conveyor pipe 3 fixedly connected to the bottom of the raw material box 2. The rotating spiral blade 6 conveys the solid raw materials forward, pushing the solid raw materials to move towards the discharge pipe 4, pushing open the sealing plate 10 at the opening of the conveyor pipe 3. When the solid raw materials reach the discharge pipe 4, the discharge pipe 4 is opened. After pipe 4, it automatically falls into mixing box 1. During the conveying process, spring 8 installed in sleeve 7 presses between sleeve 7 and movable rod 9, so that sealing plate 10 fixedly installed at the end of movable rod 9 is always facing the opening of conveying pipe 3. Since the size of sealing plate 10 is adapted to the size of the opening of conveying pipe 3, it can prevent the raw material from leaking when not conveying. When it is necessary to stop the solid raw material conveying, stop conveying motor 5, the spiral blade 6 stops rotating, and the solid raw material no longer conveys forward. Observe the scale on the side of raw material box 2 to achieve accurate quantitative feeding of solid raw material. When feeding liquid raw materials, start the electric telescopic rod 15. The output shaft of the electric telescopic rod 15 drives the connecting plate 16 to move downward. The connecting plate 16 drives the vertical rod 13 to move downward. The vertical rod 13 drives the piston 14 to slide downward in the raw liquid pipe 11. Under the pressure of the piston 14, the liquid raw materials in the raw liquid pipe 11 push open the valve 12 at the bottom and flow into the mixing box 1. By observing the scale and controlling the extension and retraction length of the electric telescopic rod 15, the feeding amount of liquid raw materials can be precisely controlled. After the solid and liquid raw materials of the coated sand are fully proportioned and fed, the stirring motor 171 at the top of the mixing tank 1 is started, which drives the rotating rod 172 to rotate. The stirring rod 173 on the rotating rod 172 stirs and mixes the solid and liquid raw materials that enter the mixing tank 1. This raw material proportioning device for coated sand production can accurately proportion and mix solid and liquid raw materials separately, ensuring the consistency of coated sand quality and making it highly practical. in, The raw material tank 2 and the raw liquid pipe 11 are provided in at least two sets, which can store, mix and feed a variety of solid and liquid raw materials; When not in use, the sealing cap 18 is threaded onto the top of the raw material box 2 to prevent external dust, moisture, etc. from entering the raw material box 2, avoid the raw materials from getting damp and deteriorating, ensure the quality of the raw materials, and ensure that the raw materials can play a normal role in subsequent use and meet the requirements of coated sand production. When the electric telescopic rod 15 drives the connecting plate 16 to rise and fall vertically, the connecting rod 20 on the connecting plate 16 will drive the movable sleeve 19 to rise and fall vertically on the raw liquid tube 11 in sync. During the sliding process of the movable sleeve 19 on the outer wall of the raw liquid tube 11, it can clean the stains that may be attached to the outer wall of the raw liquid tube 11, prevent the residual liquid from drying on the outer wall of the raw liquid tube 11, and affect the observation of the scale on the raw liquid tube 11.
