DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0029] Please refer to Figures 1-6 , the present utility model provides a technical solution: a sand mixer with a cooling function, including a base 1, a sand mixing box body 2, a water pump 3, a water tank 4, a circulating water pipe 5, a fixing bracket 6, a first motor 7, a first threaded rod 8, a support frame 9, a cover body 10, a second motor 11, a rotating rod 12, a third motor 13, a second threaded rod 14, a screw sleeve 15, a card slot block 16, a first stirring rod 17, and a second stirring rod 18;

[0030] Embodiment 1: Please refer to Figure 1 , Figure 2 , Figure 4 and Figure 5 , when the existing sand mixer is in use, it is not convenient to control the temperature of the sand material. Therefore, when the sand material continuously rubs during the mixing process, a lot of heat is generated, which easily affects the performance of the sand mixer. To solve this technical problem, the following technical content is disclosed in this embodiment.

[0031] A sand mixer with a cooling function includes a base 1. The upper end of the base 1 is fixedly connected to a sand mixing box body 2, and a circulating water pipe 5 is connected to the inner bottom layer of the sand mixing box body 2 in a card slot manner. Moreover, the front outer side of the circulating water pipe 5 is fixedly connected to a water tank 4, the rear outer side of the water tank 4 is fixedly connected to a water pump 3, and the rear outer side of the water pump 3 is fixedly connected to the left side of the rear end of the circulating water pipe 5.

[0032] When the sand mixer needs to be cooled, by controlling the water pump 3, the cold water inside the water tank 4 is pumped into the inside of the circulating water pipe 5 through the water suction pipe arranged at the upper end of the water pump 3. The circulating water pipe 5 is laid on the inner bottom layer of the sand mixing box body 2. After multiple sections of circular movement, the circulating water pipe 5 cools the sand material being mixed inside the sand mixing box body 2. The water inside the circulating water pipe 5 that has absorbed heat then enters the inside of the water tank 4 through the left side of the front end of the circulating water pipe 5, which can uniformly dissipate heat from the sand material, avoiding a large amount of heat energy generated during the friction of the sand material and affecting the sand mixer.

[0033] Embodiment 2: Please refer to Figures 1-3 , when the existing sand mixer is in use, it is not convenient to automatically lift the cover of the sand mixer. Therefore, when it is necessary to check the mixing condition of the sand material inside the sand mixer, manual operation is required, which is relatively inconvenient to use. To solve this technical problem, the following technical content is disclosed in this embodiment.

[0034] A sand mixer with a cooling function includes a fixed bracket 6. Inside the upper end of the fixed bracket 6, a first threaded rod 8 is rotatably connected. The upper end of the first threaded rod 8 is fixedly connected to a first motor 7, and the outside of the first motor 7 is fixedly connected to the fixed bracket 6. Moreover, the outside of the first threaded rod 8 is threadedly connected to a support frame 9. The lower end outside of the first threaded rod 8 is rotatably connected inside the right end of the base 1. Inside the front and rear ends on the left side of the support frame 9, a cover body 10 is fixedly connected.

[0035] When it is necessary to check the mixing condition of the sand material, by controlling the first motor 7 to drive the first threaded rod 8 to rotate, the outside of the upper end of the first threaded rod 8 is inside the fixed bracket 6, and the outside of the lower end of the first threaded rod 8 rotates inside the right end of the base 1. By using the thread on the outside of the first threaded rod 8, the movement of the support frame 9 is realized. Thus, the cover body 10 fixedly connected to the inside of the left end of the support frame 9 moves up or down. When the support frame 9 moves up, the outside of the left and right ends of the cover body 10 is disengaged from the card slot connection with the sand mixing box body 2. When the support frame 9 moves down, the outside of the left and right ends of the cover body 10 is connected to the card slot with the sand mixing box body 2, closing the upper part of the sand mixing box body 2. It can automatically lift the cover and check the mixing condition of the sand material at any time, avoiding a small amount of particles from floating in the air when the sand material is mixed.

[0036] Example 3: Please refer to Figure 1 、 Figure 2 and Figure 6 . When the existing sand mixer is in use, it is not convenient to disassemble the stirring rod for maintenance or replacement. Thus, when the stirring rod in the sand mixer is used for a long time, it is easy to become loose. To solve this technical problem, the following technical content is disclosed in this example.

[0037] A sand mixer with a cooling function includes a cover body 10. A second motor 11 is installed outside the upper end of the cover body 10, and the lower end of the second motor 11 is fixedly connected to a rotating rod 12. Moreover, a third motor 13 is installed inside the lower end of the rotating rod 12. The lower end of the third motor 13 is fixedly connected to a second threaded rod 14. The outside of the second threaded rod 14 is threadedly connected to a screw sleeve 15. Moreover, the outside of the screw sleeve 15 is rotatably connected to a card slot block 16. The outside of the card slot block 16 is connected to a first stirring rod 17 through a card slot. The left and right ends outside of the first stirring rod 17 are both fixedly connected to second stirring rods 18. Moreover, the outside of the upper end of the first stirring rod 17 is connected to the rotating rod 12 through a card slot.

[0038] When it is necessary to disassemble the stirring rod for maintenance or replacement, the third motor 13 is controlled to rotate the second threaded rod 14, so that the sleeve 15 threadedly connected to the outside of the second threaded rod 14 rotates, and drives the clamping groove block 16 rotatably connected to the outside of the sleeve 15 to move inward, so that the outside of the clamping groove block 16 is disengaged from the clamping groove connection with the first stirring rod 17, and the first stirring rod 17 is pulled downward, so that the outside of the upper end of the first stirring rod 17 is disengaged from the clamping groove connection with the rotating rod 12, and the new first stirring rod 17 is pushed upward, so that the outside of the upper end of the first stirring rod 17 is clamped and connected to the rotating rod 12, and the third motor 13 is started to drive the second threaded rod 14 fixedly connected to the lower end of the third motor 13 to rotate, so that the sleeve 15 threadedly connected to the outside of the second threaded rod 14 rotates, drives the clamping groove block 16 rotatably connected to the outside of the sleeve 15 to move outward, so that the outside of the clamping groove block 16 is clamped and connected to the first stirring rod 17 to limit the first stirring rod 17, and the second motor 11 is started to drive the rotating rod 12 fixedly connected to the lower end of the second motor 11 to rotate, driving the first stirring rod 17 to rotate. At the same time, the second stirring rods 18 fixedly connected to the outside of the left and right ends of the first stirring rod 17 stir the sand material. The stirring rod can be quickly disassembled for maintenance or replacement, avoiding the situation that the stirring rod has a high usage frequency and its quality deteriorates and cannot be replaced.
