Spraying is carried out through the spray pipe, and the fan blows the water mist out, which has a good dust suppression effect; the conical protrusion design prevents the material from sinking directly to the bottom.

[0003] The scraper blades on the stirring rod of this structure mainly scrape and stir the material in the middle of the barrel. The stirring of the material in the inner wall area of ​​the barrel is relatively weak, resulting in uneven mixing of the material in the central and edge areas of the barrel, which affects the final sand mixing quality. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a sand mixing device for sand making, which aims to improve the problem of relatively weak material mixing in the inner wall area in the prior art.

A slide rail is fixedly connected to the left side of the inner wall of the convex cavity. A discharge baffle is fixedly connected to the bottom wall of the connecting block. A circular cavity is formed on the right side of the inner wall of the convex cavity.

[0007] As a preferred embodiment of this utility model, the top of the feed tube is provided with a dome, and one side of the dome is rotatably connected to one side of the feed tube via a hinge.

[0008] As a preferred embodiment of this utility model, a spiral scraper is fixedly connected to one end of each of the multiple long rods, and blades arranged in a ring array are fixedly connected to the outer wall of the long rods.

[0009] As a preferred embodiment of this utility model, the outer wall of the chassis is fixedly connected to a support plate arranged in a ring array, and a controller is fixedly connected to the outer wall of one of the support plates.

[0010] As a preferred embodiment of this utility model, a rubber pad is installed on the bottom wall of the discharge baffle, and the discharge baffle is disposed at the top of the discharge port.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Reference Figs. 1 to 4 This utility model provides an embodiment of a sand mixing device for sand making, including a machine body 1, a chassis 2 provided on the bottom wall of the machine body 1, a cover plate 13 fixedly connected to the top of the machine body 1, a feed pipe 14 fixedly connected to the top of the cover plate 13, a hollow column 3 fixedly connected to the bottom wall of the chassis 2, the chassis 2 provides stable support for the machine body 1 to ensure that the equipment is placed stably; the hollow column 3 is fixed to the bottom wall of the chassis 2 to provide installation space for a medium-sized motor 4, the motor drives the subsequent mixing components to operate; the cover plate 13 covers the top of the machine body 1 and is fixedly connected to the feed pipe 14, which not only facilitates the input of materials, but also prevents material splashing and dust escape to a certain extent.

[0023] The hollow column 3 houses a medium-sized motor 4, the output of which is fixedly connected to a long column 5. A long rod 6 is fixedly connected to the outer wall of the long column 5. Multiple long rods 6 are arranged in a linear array of two to a group, with each group symmetrically distributed. A discharge port 18 is located on one side of the chassis 2, with a discharge guide plate 9 fixedly connected to the bottom wall of the discharge port 18. A telescopic assembly is installed inside the chassis 2. The medium-sized motor 4 inside the hollow column 3 is the power source, driving the long column 5 to rotate, which in turn drives the long rod 6 and blades 8 to mix the material. A spiral scraper 7 rotates with the long column 5 to assist in material mixing and prevent accumulation. The discharge port 18 is used to discharge the mixed material. The discharge guide plate 9, in conjunction with the telescopic assembly inside the chassis 2, controls the discharge, ensuring orderly sand mixing and discharge.

[0024] The top of the feed pipe 14 is provided with a dome 16. One side of the dome 16 is rotatably connected to one side of the feed pipe 14 via a hinge 15. One end of each of the multiple long rods 6 is fixedly connected to a spiral scraper 7. The outer wall of the long rods 6 is fixedly connected to blades 8 arranged in a ring array. The outer wall of the chassis 2 is fixedly connected to a support plate 10 arranged in a ring array. One of the support plates 10 is fixedly connected to a controller 11. The dome 16 at the top of the feed pipe 14 rotates via the hinge 15, which is convenient for opening and closing. This not only prevents dust from being blown out during feeding but also facilitates the input of materials. The spiral scraper 7 is fixed to the long rods 6 in multiple places to enhance the mixing and conveying effect. The support plate 10 is arranged in a ring array to support the chassis 2, ensuring the stability of the equipment. The controller 11 is installed on the support plate 10, which is convenient for the operator to operate the equipment.

[0025] The telescopic assembly includes a convex cavity 201, which is located inside one side of the chassis 2. A connecting block 204 is provided inside the convex cavity 201. A rack 207 is fixedly connected to the right side of the connecting block 204, and a slider 203 is fixedly connected to the left side of the connecting block 204. A slide rail 202 is fixedly connected to the left side of the inner wall of the convex cavity 201, and a discharge baffle 205 is fixedly connected to the bottom wall of the connecting block 204. In the telescopic assembly, the convex cavity 201 provides space for the internal components. The connecting block 204 slides on the slide rail 202 via the slider 203 to ensure movement stability. The rack 207 is connected to the connecting block 204 and works with the subsequent gear 209 to achieve precise displacement. The discharge baffle 205 is fixed to the bottom wall of the connecting block 204 and is used to control the opening and closing of the discharge port 18 to achieve precise control of material discharge.

[0026] A circular cavity 208 is formed on the right side of the inner wall of the convex cavity 201. A rubber pad 206 is installed on the bottom wall of the discharge baffle 205, which is located at the top of the discharge port 18. The outer wall of the slide rail 202 is slidably connected to the inside of the slider 203. A round cover 12 is fixedly connected inside the circular cavity 208. A small motor 17 is installed inside the round cover 12. A gear 209 is fixedly connected to the output end of the small motor 17. The gear 209 meshes with the rack 207. The output end of the small motor 17 is fixedly connected to the middle of the gear 209. The gear 209 is installed in the circular cavity 208 and cooperates with the rack 207. Under the drive of the small motor 17, the movement of the connecting block 204 is precisely controlled. The circular cover 12 is fixed inside the circular cavity 208 to protect the small motor 17. The discharge baffle 205 is on the top of the discharge port 18. The bottom wall rubber pad 206 enhances the sealing. The slider 203 cooperates with the slide rail 202 to ensure the stable movement of the connecting block 204.

[0027] Working principle: During operation, the equipment is first turned on by the controller 11. The material enters through the feed pipe 14. The dome 16 at the top of the feed pipe 14 can be opened and closed by the hinge 15 for easy feeding. The medium motor 4 is located inside the hollow column 3. After starting, its output end drives the long column 5 to rotate. The long rod 6 fixed on the long column 5 rotates accordingly. The blades 8 at both ends of the long rod 6 stir the material, causing the material to mix in the machine body 1. At the same time, the spiral scrapers 7 on both sides of the outer wall of the long column 5 also rotate with the long column 5, conveying the material from the bottom up or from the top down, further enhancing the mixing effect of the material and preventing the material from accumulating in one place. After mixing is completed, the telescopic component inside the chassis 2 controls the discharge guide plate 9 to open, and the material is discharged from the discharge port 18. The support plate 10 supports the machine body 1, and the controller 11 allows the operator to control the operation of the equipment.

[0028] When material discharge needs to be controlled, the small motor 17 is started by the controller 11. The small motor 17 is located inside the round cover 12. Its output end drives the gear 209 to rotate in the round cavity 208. Since the gear 209 meshes with the rack 207, when the gear 209 rotates, the rack 207 will move horizontally in the convex cavity 201. The rack 207 is fixedly connected to the connecting block 204. The slider 203 on the left side of the connecting block 204 slides on the slide rail 202 to ensure the stability of the movement of the connecting block 204. The discharge baffle 205 fixed to the bottom wall of the connecting block 204 moves accordingly. When the discharge baffle 205 moves to one side, the discharge port 18 opens and the material is discharged; otherwise, it closes. The rubber pad 206 on the bottom wall of the discharge baffle 205 can ensure the sealing when closed to prevent material leakage and achieve precise adjustment of the discharge amount to meet different production needs.
