[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Example 1

[0027] Reference Figures 1-2 A multi-channel precision metering rice dispensing machine includes a support frame 1, on which a hopper 2 is mounted. The support frame 1 includes a fixed frame fixed to the outer wall of the hopper 2, and multiple support blocks are fixed on the fixed frame. Support legs are fixed to the bottom of each of the multiple support blocks. Multiple dispensing pipes 3 are installed at the bottom of the hopper 2. A feeding and metering mechanism capable of synchronous feeding is installed inside the dispensing pipes 3. The feeding and metering mechanism includes two arc-shaped plates 6 fixed inside the dispensing pipes 3. The upper and lower ends of the two arc-shaped plates 6 do not abut each other, thus forming an inlet and an outlet.

[0028] A metering column 7 is rotatably connected between two arc-shaped plates 6. A motor 4 is installed on one of the dispensing tubes 3. The output end of the motor 4 is fixedly connected to the metering column 7. Two adjacent metering columns 7 are connected by a transmission rod 5. The metering column 7 is provided with multiple metering grooves 8, which are arranged in a circular array outside the metering column 7. When the metering column 7 rotates, the rice falls into the metering grooves 8 due to gravity. When the metering grooves 8 rotate to the lower side, the rice is discharged due to gravity.

[0029] Rice is conveyed in the hopper 2 by a screw conveyor. The motor 4 is started, and the motor 4, together with the transmission rod 5, makes multiple metering columns 7 rotate simultaneously. When the metering trough 8 is on the upper side, the rice falls into the metering trough 8 due to gravity. When the metering column 7 drives the rice in the metering trough 8 to rotate to the lower side, the rice can be discharged. In this way, the rice can be metered and discharged through multiple dispensing pipes 3, which improves the dispensing efficiency of rice.

[0030] Example 2

[0031] Reference Figure 3The difference between this embodiment and embodiment 1 is that this embodiment also includes a threaded rod 9 that can rotate with the metering column 7. The threaded rod 9 is rotatably installed in the hopper 2. A movable plate 10 is threadedly connected to the outside of the threaded rod 9. Multiple dispersing rods 12 are fixed at the bottom of the movable plate 10. A guide rod 11 is fixed inside the hopper 2. The guide rod 11 passes through the movable plate 10 and is slidably connected to it. A shaft 13 is fixed on both the threaded rod 9 and the metering column 7. A transmission wheel 14 is installed on both shafts 13. The two transmission wheels 14 are connected by a belt 15.

[0032] Through the transmission of shaft 13, drive wheel 14, and belt 15, the threaded rod 9 can rotate. The rotation of the threaded rod 9 causes the moving plate 10, which is guided by the guide rod 11, to move. The movement of the moving plate 10 drives the dispersing rod 12 to move, which can evenly disperse the rice conveyed to the hopper 2, so as to ensure that each dispensing tube 3 can be stably dispensed with rice.

[0033] Example 3

[0034] Reference Figures 4-5 The difference between this embodiment and embodiments 1 and 2 is that this embodiment also includes a dust removal mechanism. The dust removal mechanism includes a dust collection box 16 installed on the upper end of the moving plate 10. A fan 17 and a suction pipe 18 are installed on the dust collection box 16. A dust filter plate 20 is installed inside the dust collection box 16. The fan 17 and the suction pipe 18 are located on both sides of the dust filter plate 20. The movement of the moving plate 10 causes the dust collection box 16 to move with the dispersing rod 12. The fan 17 works at the inlet of the suction pipe 18 to form a negative pressure, so that the dust can be sucked into the dust collection box 16 through the suction pipe 18. The dust can be removed and collected by the filtration of the dust filter plate 20.

[0035] Since a cover plate 19 is fixed to the upper end of the dust filter plate 20, and the cover plate 19 is connected to the dust collection box 16 by magnetic attraction, and rectangular magnetic blocks are fixed on both the cover plate 19 and the dust collection box 16, the two attract each other to fix the cover plate 19. Therefore, by pulling up the cover plate 19, the dust filter plate 20 can be removed so that its surface can be cleaned.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
