[0021] The present application is further described in detail below in conjunction with the accompanying drawings.

[0022] The present application discloses an automatic stirring and mixing device, referring to Figure 1 , including a mixing bin 1, a discharge pipe 10, a motor 13 and a rotating rod 14, characterized in that a feeding device that can simultaneously input multiple materials and control the input amount of each material is provided on the top of the mixing bin 1, the feeding device can input the materials to be mixed into the mixing bin 1, and the outer wall of the mixing bin 1 is provided with a temperature control device for adjusting the internal temperature of the mixing bin 1. The temperature in the mixing bin 1 can be adjusted by the temperature control device to achieve the most suitable temperature for material mixing, which can effectively improve the material mixing rate. The discharge pipe 10 is connected to the bottom of the mixing bin 1, and the motor 13 is connected to the top of the mixing box 1. The output end of the motor 13 is transmission-connected to the rotating rod 14. The rotating rod 14 is provided with a plurality of stirring rods 15 along the length direction. When the motor 13 is started, the rotating rod 14 can be driven to rotate. At this time, the stirring rod 15 on the outer wall of the rotating rod 14 can rotate to stir the materials inside the mixing bin 1. The top of the mixing bin 1 is provided with a lifting device for controlling the motor 13 to move toward or away from the top of the mixing bin 1.

[0023] In this embodiment, a discharge valve 11 is provided inside the discharge pipe 10. The discharge valve 11 can be opened and closed by remote control. When mixing, the discharge valve 11 can be closed to allow the materials in the mixing bin 1 to be fully mixed. Then, the discharge valve 11 can be opened to take out the mixed materials in the mixing bin 1.

[0024] Furthermore, the bottom of the mixing bin 1 is conical, which is convenient for discharging materials. The four ends of the bottom of the mixing bin 1 are connected with supporting legs 2 to maintain the stability of the mixing bin 1.

[0025] Reference Figure 2 and Figure 3The feeding device includes a storage box 3 and a feeding pipe 7. The storage box 3 is connected to the top of the mixing bin 1, one end of the feeding pipe 7 is connected to the storage box 3, and the other end of the feeding pipe 7 is connected to the discharge port of the spiral feeder. The spiral feeder can automatically transport the material to the feeding pipe 7 without manual dumping, saving manpower. A feeding valve 18 is provided at the bottom of the storage box 3, and a pressure sensor 17 is connected to the inner wall of the storage box 3. When the material enters the storage box 3 through the feeding pipe 7, the bottom of the storage box 3 is kept closed by remotely controlling the feeding valve 18. At this time, the material begins to accumulate in the storage box 3. When the material fills the inside of the storage box 3, the pressure sensor 17 detects the pressure, and at this time the spiral feeder is closed to stop the material input, and then by opening the feeding valve 18 and controlling the opening time of the feeding valve 18, a certain amount of material can be put into the mixing bin 1.

[0026] In the present embodiment, there are several storage boxes 3 connected to the top of the mixing bin 1, and each storage box 3 is connected to the feed pipe 7, and is provided with a pressure sensor 17 and a feed valve 18. When a plurality of materials need to be mixed, it is only necessary to put each material into a different storage box 3 and monitor whether the storage box 3 is full through the pressure sensor 17. Then, by controlling the opening and closing of each feed valve 18, each material can be put into the mixing bin 1 according to different quantities, and the proportion of each material can be accurately adjusted to achieve the best material mixing ratio, which can improve the quality of the finished product after the materials are mixed.

[0027] Reference Figure 1 and Figure 2 The temperature control device includes a heating pipe 8, an air inlet pipe 9 and a temperature sensor 16. The heating pipe 8 is sleeved on the outer wall of the mixing bin 1 and communicated with the interior of the mixing bin 1. The air inlet pipe 9 is connected to the heating pipe 8. The temperature sensor 16 is connected to the inner wall of the mixing bin 1. The temperature in the mixing bin 1 can be measured in real time by the temperature sensor 16. When the temperature in the mixing bin 1 does not meet the optimal temperature for material mixing, the air supply end of the hot air blower can be connected to one end of the air inlet pipe 9 to inject hot air into the mixing bin 1, so that the temperature in the mixing bin 1 is increased to reach the optimal temperature for material mixing.

[0028] It should be noted that the warm air needs to be filtered through a filter assembly before entering the air inlet pipe 9 to filter out moisture and impurities in the warm air to prevent them from affecting the mixing of materials. The outer shell of the mixing bin 1 is made of thermal insulation material, and the outer wall of the heating pipe 8 is provided with an insulation layer. The warm air will not lose most of the heat during transportation and when entering the mixing bin 1.

[0029] Reference Figure 1 and Figure 2The lifting device includes a bracket 4, a sliding plate 6 and a telescopic device 12. The bracket 4 is connected to the top of the mixing bin 1. Slide grooves 5 are provided on both sides of the bracket 4 that are close to each other. The two ends of the sliding plate 6 are respectively slidably connected to the two slide grooves 5. The telescopic end of the telescopic device 12 is connected to the sliding plate 6. The telescopic device 12 can adopt an electric telescopic rod. The fixed end of the telescopic device 12 is connected to the top of the mixing bin 1, and the sliding plate 6 is connected to the fixed end of the motor 13. When the height of the motor 13 needs to be adjusted, the position of the sliding plate 6 can be raised by starting the telescopic device 12 to drive the position of the motor 13 to rise. When the material is stirred, since the position of the motor 13 can be adjusted, the stirring rod 15 on the outer wall of the rotating rod 14 can be lifted and lowered with the lifting and lowering of the motor 13. At this time, the stirring rod 15 can stir the materials at different positions, so that the materials can be mixed more fully.

[0030] The implementation principle of an automatic stirring and mixing device in the embodiment of the present application is as follows: when mixing multiple materials, different materials can be put into different storage boxes 3, and the pressure sensor 17 can monitor whether the materials fill the storage boxes 3, and then the opening and closing of the feed valve 18 can be remotely controlled. The opening and closing time of the feed valve 18 can control the amount of each material put into the mixing bin 1, so as to control the ratio of each material, so that the materials can reach the best mixing ratio, and the quality of the mixed material products can be improved. The temperature in the mixing bin 1 is monitored in real time by the temperature sensor 16. When the temperature is lower than the optimal temperature, the heating air is passed into the heating pipe 8 through the air inlet pipe 9. The heating pipe 8 is connected to the inside of the mixing bin 1, and the temperature in the mixing bin 1 will rise. When the temperature is adjusted to the optimal temperature, the heating input can be stopped, so that the optimal temperature of material mixing in the mixing bin 1 can be maintained. By starting the motor 13 to drive the rotating rod 14 to rotate, the stirring rod 15 can be driven to rotate, and the stirring function can be achieved. At this time, starting the telescopic device 12 to push the sliding plate 6 to slide up and down between the brackets 4 can drive the motor 13 to rise and fall, and the height of the stirring rod 15 can be adjusted, so that the stirring rod 15 can stir the materials at different positions inside the mixing bin 1, so that the materials are mixed more fully, thereby achieving the effect of increasing the material mixing rate.

[0031] Finally, a few points should be explained: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, and can be mechanical or electrical connections, or internal connectivity between two components, or direct connections. "Up", "down", "left", "right", etc. are only used to indicate relative position relationships.

Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
