Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor fall within the protection scope of the utility model.

[0030] Embodiment:

[0031] A multi-sand mixing and stirring machine comprises a support frame 3, a material tank 1, a feeding device 5 and a mixing device 4; the material tank 1, the feeding device 5 and the mixing device 4 are arranged in sequence from top to bottom on the support frame 3 and are connected with each other; the material tank 1 is used for storing sand, and the mixing device 4 is used for mixing sand; the feeding device 5 comprises a mounting shell 13, a first driving device 14, a transfer shaft 12 and an auxiliary shaft 9; the top of the mounting shell 13 is communicated with the material tank 1, and the bottom is communicated with the mixing device 4 through a feeding opening 15; the transfer shaft 12 and the auxiliary shaft 9 are both rotationally connected in the mounting shell 13; the transfer shaft 12 is located at one side close to the bottom of the mounting shell 13, and the auxiliary shaft 9 is located at one side close to the top of the mounting shell 13; the transfer shaft 12 is provided with auger blades 11, and the auxiliary shaft 9 is fixedly connected with a plurality of eccentric blocks 10; the first driving device 14 is used for driving the transfer shaft 12 and the auxiliary shaft 9 to rotate.

[0032] The material tank 1 is used for storing various sand materials, such as new sand, old sand, resin particles, clay particles and the like. Meanwhile, the bottom of the material tank 1 is also provided with a valve, which controls the opening and closing of the bottom of the material tank 1, so as to put the materials into the feeding device 5. The mounting shell 13 has an inner cavity, and the transfer shaft 12 and the auxiliary shaft 9 are arranged in the inner cavity. The auger blades 11 on the transfer shaft 12 are used to push the sand to move, and push the sand to the feeding opening 15, so as to ensure that the sand can enter the mixing device 4. When the auxiliary shaft 9 rotates, the eccentric blocks 10 on the auxiliary shaft 9 can scatter the sand to prevent the caked sand from blocking the feeding opening 15. At the same time, the eccentric blocks 10 on the auxiliary shaft 9 will drive the auxiliary shaft 9 to vibrate when rotating, and the auxiliary shaft 9 will transmit the vibration to the mounting shell 13 body, and the mounting shell 13 body will transmit the vibration to the material tank 1, which can effectively reduce the risk of sand blocking at the bottom of the material tank 1. The first driving device 14 can adopt a motor. Specifically, in use, the bottom of the material tank 1 is opened, and the sand in the material tank 1 enters the mounting shell 13. The first driving device 14 is turned on, which drives the transfer shaft 12 and the auxiliary shaft 9 to rotate, and the eccentric blocks 10 on the auxiliary shaft 9 scatter the sand, and the scattered sand falls to the bottom of the mounting shell 13. At the same time, the eccentric blocks 10 drive the auxiliary shaft 9 and the mounting shell 13 to vibrate to avoid sand blocking. The transfer shaft 12 pushes the sand to the feeding opening 15 when rotating, and the sand enters the mixing device 4 from the feeding opening 15, and the sand entering the mixing device 4 is stirred and mixed. Through this design, efficient sand mixing and stirring can be ensured, and the degree of automation is high. Since the auxiliary shaft 9 and the eccentric blocks 10 are used, the sand feeding process will be smoother and less likely to be blocked.

[0033] In a preferred embodiment, the top of the mounting frame is fixedly connected with a tank rack 2, and the material tank 1 is provided with a plurality of material tanks 1, each of which is arranged on the tank rack 2; each of the plurality of material tanks 1 is connected with the feeding device 5. Specifically, in this embodiment, the material tank 1 is provided with four material tanks 1, each of which is used to store new sand, old sand, resin particles and clay particles; different specifications of sand materials are prepared by adjusting the proportion of the materials. The tank rack 2 is designed to fix the position of the material tank 1 and ensure the stability of the material tank 1.

[0034] In a preferred embodiment, the top of the mounting shell 13 is provided with a feeding pipe 8, the bottom of the material tank 1 is provided with a discharge port 6, the discharge port 6 is connected with the feeding pipe 8, and the feeding pipe 8 is further provided with a plug valve 7. The discharge port 6 is an inclined groove structure, which is used to make the material at the bottom of the material tank 1 flow into the feeding pipe 8. Specifically, when in use, the plug valve 7 is opened, and the feeding pipe 8 is also opened. The sand material in the material tank 1 enters the feeding pipe 8 through the discharge port 6, and then enters the feeding device 5 through the feeding pipe 8.

[0035] In a preferred embodiment, the plug valve 7 is a pneumatic plug valve 7. The plug valve 7 can effectively close the discharge port 6 to prevent the sand material from flowing out at will when it is not needed, thereby ensuring the cleanliness of the system and the efficient use of the material. The use of the pneumatic plug valve 7 can significantly improve the degree of automation. Through pneumatic control, the plug valve 7 can quickly adjust the opening and closing degree of the discharge port 6, thereby accurately controlling the flow of sand material entering the mounting shell 13.

[0036] In a preferred embodiment, the discharge port 15 is located on one side of the bottom of the mounting shell 13, and the transfer shaft 12 is used to drive the auger blade 11 to push the sand material to the discharge port 15. The transfer shaft 12 drives the auger blade 11 to continuously push the sand material by rotating, so that the sand material continuously approaches the discharge port 15. This continuous stirring and pushing process not only helps the uniform distribution of the sand material, but also ensures that all types of sand material reach a good mixing state before entering the mixing device 4, thereby ensuring the mixing effect. The rotating movement of the transfer shaft 12 can effectively avoid the accumulation and caking of the sand material near the discharge port 15, thereby reducing the risk of blockage of the machine during operation.

[0037] In a preferred embodiment, the mixing device 4 includes an assembly shell 19, a mixing shaft 18, mixing blades 16 and a second driving device 20; the mixing shaft 18 is rotatably connected in the assembly shell 19, one side of the mixing shaft 18 extends out of the assembly shell 19 and is connected with the second driving device 20, and the mixing blades 16 are connected on the mixing shaft 18.

[0039] In a preferred embodiment, two mixing blades 16 are provided, and the two mixing blades 16 are in a double spiral structure. A connecting rod 17 is arranged between the mixing blades 16 and the mixing shaft 18. One end of the connecting rod 17 is fixedly connected with the mixing blade 16, and the other end is fixedly connected with the mixing shaft 18. The mixing blades 16 in the double spiral structure can form a complementary stirring effect when rotating. On the one hand, one blade pushes the sand to diffuse outward, and on the other hand, the other blade pushes the sand to flow back inward, forming a continuous circulating flow. Such interaction significantly improves the mixing uniformity and efficiency of the sand.

[0040] In a preferred embodiment, the bottom of the assembly shell 19 is provided with a discharge port 21. A discharge door 22 is slidably connected in the discharge port 21. The discharge door 22 is designed to facilitate the discharge of the mixed material. The combination of the discharge port 21 and the discharge door 22 enables the mixed material to be quickly and smoothly discharged, avoiding the long-term accumulation of the material in the mixing container, ensuring the efficient operation of the production link, and improving the overall work efficiency.

[0041] In a preferred embodiment, the bottom of the assembly shell 19 is fixedly connected with a discharge cylinder 23. The telescopic rod of the discharge cylinder 23 is connected with the discharge door 22. The discharge cylinder 23 is used to control the opening and closing of the discharge door 22. The introduction of the discharge cylinder 23 enables the discharge process of the material to be automated. The operator only needs to start or stop the discharge door 22 through a simple control system, thereby greatly reducing the complexity and labor intensity of manual operation and improving the work efficiency.
