[0021] The following will clearly and completely describe the technical solution of the present invention in conjunction with the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Reference Figures 1 to 4 The utility model provides a technical solution: a biofertilizer mixing device, including a mixing barrel 10, the outer wall and the bottom of the mixing barrel 10 are respectively connected to the feed hopper 3 and the discharge pipe 13, such as Figure 1 As shown, the top of the mixing barrel 10 is sealed by a detachable top cover 2, and the top cover 2 and the mixing barrel 10 are connected in a detachable manner, which facilitates the staff to inspect and repair the inside of the device and replace parts, thereby extending the service life of the device.

[0023] like Figure 2 、 3 As shown, the center of the top cover 2 is rotatably connected to the first connecting shaft 7, and a second connecting shaft 8 rotatably connected to the top cover 2 is symmetrically provided along the first connecting shaft 7. The top of the top cover 2 is connected to the drive motor 1, and the top of the first connecting shaft 7 is fastened to the output of the drive motor 1. The second connecting shaft 8 and the first connecting shaft 7 located below the top cover 2 are respectively fixedly connected with a driven wheel 17 and a driving wheel 18, and the driving wheel 18 is engaged with the driven wheels 17 located on both sides. In order to protect the driven wheel 17 and the driving wheel 18, an annular support 16 is fastened to the bottom of the top cover 2, and the annular support 16 is connected to the mounting seat 20. The second connecting shaft 8 and the first connecting shaft 7 are rotatably connected to the mounting seat 20, and the driven wheel 17 and the driving wheel 18 are located between the top cover 2 and the mounting seat 20. In order to facilitate the staff to disassemble and install the mounting seat 20, bolts are used to fasten the mounting seat 20 to the annular support 16.

[0024] like Figure 3 、 4As shown, the second connecting shaft 8 and the first connecting shaft 7 extending into the mixing barrel 10 are respectively connected to the first spiral blade 5 and the second spiral blade 6, and the second spiral blade 6 and the first spiral blade 5 have opposite rotation directions. The first spiral blade 5 pushes the fertilizer pushed upward by the second spiral blade 6 in the opposite direction, and the driving motor 1 drives the active wheel 18 to rotate. Due to the meshing connection between the driven wheel 17 and the active wheel 18, the driven wheel 17 rotates at the same time, driving the second spiral blade 6 and the first spiral blade 5 to rotate at the same time, which can drive the feed located in the inner layer and the outer layer to move in the opposite direction. At the same time, the spiral blades drive the feed to achieve vertical lifting movement, which can ensure that the bottom feed is fully mixed.

[0025] like Figure 3 、 4 As shown, the first gear 9 is rotatably connected to the upper end of the inner wall of the mixing barrel 10 through a bearing 15, and a second gear 21 meshing with the first gear 9 is fastened to the second connecting shaft 8. When the second connecting shaft 8 rotates, it drives the second gear 21 to rotate, and synchronously drives the first gear 9 to rotate on the inner wall of the mixing barrel 10. The bottom of the first gear 9 is symmetrically connected to a scraper 14 that fits the gap with the inner wall of the mixing barrel 10, and one side of the scraper 14 is horizontally connected to multiple stirring rods 4. There is a gap between the stirring rod 4 and the first spiral blade 5. The stirring rod 4 can stir and mix the feed near the inner wall of the mixing barrel 10, and the bottom of the scraper 14 is connected to an extension plate 19 that fits the gap with the inner bottom surface of the mixing barrel 10. When the second spiral blade 6 and the first spiral blade 5 rotate, under the meshing action of the first gear 9 and the second gear 21, the scraper 14 and the extension plate 19 rotate along the inner wall of the mixing barrel 10, avoiding the accumulation of feed at the bottom, thereby further realizing the mixing of the bottom feed.

[0026] To sum up, when the bio-fertilizer mixing equipment is in use, a control box 11 is connected to the outer wall of the mixing barrel 10, a controller is set in the control box 11, and the drive motor 1 is connected to the controller. In order to improve the stability of the placement of the mixing barrel 10, at least three legs 12 are fastened circumferentially at the bottom of the mixing barrel 10. When performing the mixing operation, the feed raw materials are transported from the feed hopper 3 to the mixing barrel 10, and the drive motor 1 drives the first spiral blade 5 and the second spiral blade 6 to rotate, driving the inner and outer layers of feed to move in opposite directions. At the same time, the scraper 14, the extension plate 19 and the stirring rod 4 can mix the feed near the inner wall of the refueling barrel, further improving the mixing efficiency of the feed, and also avoiding the accumulation of feed at the bottom of the mixing barrel 10.

[0027] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
