Specific implementation mode

[0021] The embodiment is given by Figures 1-5 The present utility model includes a base 1. A rectangular tube 2 is fixedly connected to the top of the base 1. A feeding mechanism is installed at the top rear side of the rectangular tube 2. A stirring mechanism is installed inside the rectangular tube 2. A circulation mechanism is installed on each side of the rectangular tube 2. The circulation mechanism includes a circular tube 11. The circular tube 11 is located on the top of the base 1 and extends into the base 1. A return pipe 12 and a discharge pipe 13 are fixedly connected between the circular tube 11 and the rectangular tube 2. The return pipe 12 is located above the discharge pipe 13. A screw rod 15 is movably connected inside the circular tube 11 through a bearing. A second motor 14 is fixedly connected to the top of the circular tube 11. The top end of the screw rod 15 is fixedly connected to the output shaft of the second motor 14. A plurality of fan-shaped discharge ports 16 are opened at the bottom of the circular tube 11.

[0022] The output shafts of the two second motors 14 in the circulation mechanism rotate at different speeds, that is, the two circulation mechanisms run at different speeds when circulating and transporting the mixed materials. There is a time difference when the two paths of mixed materials circulate back to the rectangular tube 2, so that all the materials can be fully mixed during the circulation of the mixed materials. After the mixing is completed, only need to drive the output shaft of the second motor 14 to reverse, and the mixed materials in the circular tube 11 can be conveyed downward through the screw rod 15 and discharged from the fan-shaped outlet 16 to the base 1.

[0023] The start-stop control of the first motor 7 and the second motor 14, as well as the running speed, forward and reverse rotation of the two second motors 14 can be achieved by the prior art, so the control principles of the two will not be elaborated here.

[0024] The feeding mechanism includes a mounting plate 3, which is fixedly connected to the top of the rear side of the rectangular pipe 2. A hopper 5 is installed above the mounting plate 3. The bottom of the hopper 5 is fixedly connected to a material guiding pipe 6. The material guiding pipe 6 penetrates through the mounting plate 3 and the rear side of the rectangular pipe 2 and extends into the rectangular pipe 2. Different natural materials can be proportionally introduced into the rectangular pipe 2 through the hopper 5 and the material guiding pipe 6. The part of the material guiding pipe 6 extending into the rectangular pipe 2 is located above the stirring rod 9 in the stirring mechanism, so that the materials entering the rectangular pipe 2 can be stirred by the stirring mechanism during the falling process.

[0025] Two reinforcing plates 4 are fixedly connected to the connection between the bottom of the mounting plate 3 and the rear side of the rectangular pipe 2 and are distributed left and right. The reinforcing plates 4 play a role in strengthening the mounting plate 3, which can improve the firmness and stability of the mounting plate 3.

[0026] The stirring mechanism includes a first motor 7, which is fixedly connected to the top of the rectangular pipe 2. The output shaft of the first motor 7 is fixedly connected to a rotating rod 8 through a coupling. A plurality of stirring rods 9 are fixedly connected to the outer end of the rotating rod 8. The rotating rod 8 and the stirring rods 9 are both located inside the rectangular pipe 2, and the stirring rods 9 are located between the return pipe 12 and the discharge pipe 13. The stirring mechanism can stir various natural materials entering the rectangular pipe 2 and falling downward in the air, and can fully mix all the natural materials without dead angles in cooperation with the circulation mechanism.

[0027] The bottom of the rotating rod 8 is movably connected to a stable support 10, and the rear side of the stable support 10 is fixedly connected to the inner rear side of the rectangular pipe 2. The stable support 10 plays a role in supporting and limiting the rotating rod 8, avoiding the problem of bottom shaking when the rotating rod 8 rotates, and at the same time not affecting the rotation of the rotating rod 8.

[0028] An inclined plate 17 is fixedly connected inside the base 1. A discharge port 18 is opened on one side of the base 1, and the discharge port 18 is located above the bottom of the slope of the inclined plate 17. After the mixed materials enter the base 1, they will fall onto the inclined plate 17 and slide downward along the slope direction of the inclined plate 17 until they are discharged through the discharge port 18.

[0029] The above mixing of natural materials is applicable to some powdery or granular materials. For natural materials with larger volumes, they need to be crushed and processed in advance before being mixed and proportioned in the above manner.

[0030] Working principle:

[0031] When mixing natural materials, the materials can be introduced into the interior of the rectangular pipe 2 through the hopper 5 and the material guide pipe 6. During this process, the first motor 7 drives the rotating rod 8 and the stirring rod 9 to rotate, and the stirring rod 9 stirs the materials that fall downward into the interior of the rectangular pipe 2 from the material guide pipe 6 in a suspended manner. After stirring, the mixed materials fall downward onto the roof-shaped plate 19. Subsequently, the mixed materials will be diverted by the roof-shaped plate 19 and slide toward the two discharge pipes 13. Then, they enter the interior of the circular pipe 11 through the discharge pipes 13. During this period, the second motor 14 drives the screw rod 15 to rotate forward. When the screw rod 15 rotates forward, it can convey the mixed materials entering the interior of the circular pipe 11 upward. When it is conveyed to the height of the return pipe 12, the mixed materials in the circular pipe 11 will be re-introduced into the interior of the rectangular pipe 2 through the return pipe 12 and be stirred again in a suspended manner by the stirring mechanism. Moreover, during this period, the rotational speeds of the output shafts of the two second motors 14 are one fast and one slow, that is, the two circulation mechanisms are one fast and one slow when circulating and conveying the mixed materials. Thus, all the materials can be fully mixed during the circulation of the mixed materials. After the mixing ratio of the natural materials is completed, the second motor 14 drives the screw rod 15 in the reverse direction. At this time, the screw rod 15 can convey the mixed materials entering the circular pipe 11 downward until the mixed materials fall into the inclined plate 17 in the base 1 through the fan-shaped discharge port 16. Finally, the mixed materials on the inclined plate 17 slide down along the slope to the discharge port 18. A receiving container can be placed outside the discharge port 18 to receive the mixed materials.
