The lower end of the mixing rod 703 passes through the limiting plate 702 and extends into the mixing barrel 1.
[0026] In the present application, the first bevel gear 704 rotates under the drive of the driving mechanism 9, and the rotation of the first bevel gear 704 synchronously drives the mixing rod 703 to rotate, and the rotation of the mixing rod 703 ultimately achieves the purpose of mixing the powder in the mixing barrel 1; at this time, the limiting plate 702 limits the mixing rod 703, preventing the mixing rod 703 from shaking when rotating, thereby reducing the stability of the mixing device.
[0027] Furthermore, the conveying mechanism 8 includes a conveying bin 801, the upper surface of the conveying bin 801 is fixedly connected to the lower surface of the support leg 3, the lower end of the discharge pipe 4 extends into the conveying bin 801, a rotating rod 802 is rotatably installed in the conveying bin 801, and a conveying blade 803 is fixedly connected to the outer surface of the rotating rod 802. An output port 8011 is provided on the lower surface of the outer end of the conveying bin 801, and perspective windows 804 are fixedly installed on both sides of the conveying bin 801.
[0028] In the present application, the rotating rod 802 rotates under the action of the driving mechanism 9, and the conveying blade 803 is synchronously driven to rotate through the rotation of the rotating rod 802, so that the powder discharged from the mixing barrel 1 is conveyed to the next working area, thereby improving the powder conveying efficiency; the setting of the perspective window 804 makes it convenient for the staff to intuitively see the conveying situation in the conveying bin 801, so that they can make timely processing of the conveying situation at the first time.
[0029] Furthermore, the driving mechanism 9 includes two support blocks 901, both of which are fixedly mounted on the upper surface of the mixing drum 1, and a connecting rod 902 is rotatably mounted on the two support blocks 901, and the second bevel gear 903 and the first sprocket 904 are respectively fixedly connected at both ends of the connecting rod 902, the second bevel gear 903 is meshingly connected with the first bevel gear 704, a second sprocket 905 is arranged below the first sprocket 904, the second sprocket 905 is fixedly connected to the outer end of the rotating rod 802, the first sprocket 904 and the second sprocket 905 are connected by a chain 906, a driving motor 908 is arranged on the outer side of the second sprocket 905, the output shaft of the driving motor 908 is fixedly connected to the second sprocket 905, and a mounting seat 907 is fixedly mounted on the lower surface of the driving motor 908, and the mounting seat 907 is fixedly connected to the outer wall of the conveying bin 801.
[0030] In the present application, the start of the driving motor 908 is controlled by the control panel 2, so that the driving motor 908 drives the second sprocket 905 to rotate. Under the action of the chain 906, the first sprocket 904 rotates synchronously, thereby driving the rotation of the connecting rod 902, and then the second bevel gear 903 rotates. Under the rotation of the second bevel gear 903 and the second sprocket 905, the first bevel gear 704 and the rotating rod 802 rotate synchronously, finally realizing the driving of the mixing mechanism 7 and the conveying mechanism 8.
[0031] The working principle of this utility model:
[0032] When in use, firstly, the driving motor 908 is started through the control panel 2, and then the medicine powder to be mixed is poured into the mixing barrel 1 through the upper hopper 6. Under the drive of the driving motor 908, the second sprocket 905 is driven to rotate, and under the action of the chain 906, the first sprocket 904 rotates synchronously, thereby driving the rotation of the connecting rod 902, and then the second bevel gear 903 rotates. Under the rotation of the second bevel gear 903 and the second sprocket 905, the first bevel gear 704 and the rotating rod 802 rotate synchronously;
[0033] The mixing rod 703 is synchronously driven to rotate under the rotation of the first bevel gear 704, so as to mix the powder in the mixing barrel 1.
