[0021] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0022] Please refer to the embodiments of this utility model. Figures 1-5 The following description is provided. A stainless steel dual-shaft paddle-type high-efficiency mixer includes a mixing chamber 1. The upper end of the mixing chamber 1 is rotatably connected to an end cover 2 via a hinge. Two feed hoppers 3 are fixedly connected to the upper end of the end cover 2. Two discharge holes 24 are opened on the lower end face of the mixing chamber 1. Two sealing doors 23 are rotatably connected to the lower end of the mixing chamber 1 via a hinge. The two sealing doors 23 are used to close the two discharge holes 24 respectively. Two motors 4 are fixedly connected to the left end of the mixing chamber 1. Two rotating shafts 6 are rotatably connected inside the mixing chamber 1. The output shaft ends of the two motors 4 are fixedly connected to the two rotating shafts 6 respectively. Multiple sleeves 13 and crushing blades 8 are fixedly connected to the circumferential surface of the two rotating shafts 6. Three mixing blades 7 are connected to the circumferential surface of each sleeve 13 via a connector.

[0023] The connector includes a mounting base 14, a mounting groove 15, a connecting base 16, a locking block 17, a threaded hole 18, an insertion hole 19, and a screw 20. Three mounting bases 14 are fixedly connected to the circumferential surfaces of multiple sleeves 13. Each mounting base 14 has two mounting grooves 15 inside, and a locking block 17 is slidably connected inside each of the two mounting grooves 15. A connecting base 16 is fixedly connected between the two locking blocks 17. The connecting base 16 is located inside the mounting base 14. A threaded hole 18 is provided on the right end face of the connecting base 16. An insertion hole 19 is provided on the right end face of each mounting base 14. The threaded hole 18 is located at the directly left end of the insertion hole 19. A screw 20 is inserted into the insertion hole 19, and the screw 20 is threadedly connected to the threaded hole 18. The screw 20 is connected to the connecting base 16 through the insertion hole 19 and the threaded hole 18. The mixing chamber 1, rotating shaft 6, sleeve 13, and mixing blade 7 are all made of stainless steel. The sleeve 13, along with the connecting parts and mixing blade 7, forms the mixing blades. During operation, solid veterinary feed additive raw materials are added to the mixing chamber 1 through the feed hopper 3. Then, two motors 4 drive the two rotating shafts 6 to rotate in opposite directions, thereby driving the two sets of mixing blades and crushing blades 8 to rotate in opposite directions. As the two sets of mixing blades rotate, the veterinary feed additive raw materials inside the mixing chamber 1 are mixed and stirred, while the crushing blades 8 crush and break up any clumps of raw materials. When a mixing blade 7 is damaged and needs replacement, the end cover 2 is opened, and the screw 20 is rotated to gradually disengage it from the threaded hole 18 and the insertion hole 19. The damaged connecting seat 16 and mixing blade 7 can then be removed from the mounting base 14 for individual replacement. (It should be noted that the distance between adjacent sleeves 13 and crushing blades 8, as well as the distance between the sleeve 13 at the very end of the mixing chamber 1 and the inner wall of the mixing chamber 1, are sufficient to remove the connecting seat 16 and mixing blade 7 from the mounting base 14.)

[0024] With the help of the connecting parts, this utility model can disassemble and replace the damaged stirring blades 7 individually, thereby saving costs.

[0025] In another embodiment of this utility model, please refer to Figures 1 to 3 Two left and right clamping plates 9 are fixedly connected to the front end of the end cap 2. Each clamping plate 9 has a clamping hole 10 on its front face. Two threaded rods 11 are fixedly connected to the front end of the mixing tank 1. Nuts 12 are threaded onto the circumferential surface of each threaded rod 11. The two threaded rods 11 engage with the two clamping plates 9 through the two clamping holes 10. During operation, the clamping plates 9, clamping holes 10, nuts 12, and threaded rods 11 work together to easily fix the end cap 2, ensuring it is securely positioned at the upper end of the mixing tank 1.

[0026] In another embodiment of this utility model, please refer to Figure 2 and Figure 5The mixing blades 7 are inclined and twisted, with a twist angle of 20-45°. Multiple sleeves 13 and pulverizing blades 8 are intersected on the circumferential surface of each rotating shaft 6, with the sleeves 13 on the circumferential surfaces of the two rotating shafts 6 arranged alternately. During operation, the mixing blades 7 generate stronger shearing force as they rotate, thus fully agitating and mixing the materials. Since the multiple sleeves 13 on the circumferential surface of each rotating shaft 6 form a group, the opposite rotation of the two rotating shafts 6 drives the two groups of sleeves 13 to rotate in the opposite direction. These sleeves 13 then drive the two groups of mixing blades to rotate in the opposite direction, further enhancing the mixing effect by causing the veterinary feed additive materials between the mixing blades to intersect and collide. This achieves efficient mixing of the veterinary feed additive materials inside the mixing chamber 1. (It should be noted that the pulverizing blades 8 are relatively small and do not overlap with the mixing blades 7 during rotation, therefore they do not obstruct the normal rotation of the mixing blades 7.)

[0027] In another embodiment of this utility model, see Figure 4 The bottom of the mixing tank 1 is fixedly connected to three left and right distributed fixed plates 21. The front and rear ends of the middle fixed plate 21 are rotatably connected to electric telescopic rods 22 via first support seats. The output ends of the two electric telescopic rods 22 are rotatably connected to two closed doors 23 via two second support seats. The front and rear ends of the leftmost and rightmost fixed plates 21 are rotatably connected to guide telescopic rods 25 via first support seats. The output ends of the two guide telescopic rods 25 are rotatably connected to two closed doors 23 via two second support seats. During operation, by controlling the retraction of the two electric telescopic rods 22, the two closed doors 23 can be driven to open stably along the hinges under the action of the guide telescopic rods 25, at which point the discharge hole 24 is exposed for material discharge. (It should be noted that the hinges connected to the two closed doors 23 are located on the side of the two closed doors 23 that are close to each other, so that when the two electric telescopic rods 22 are retracted, the two closed doors 23 can be opened.)

[0028] In another embodiment of this utility model, please refer to Figures 1 to 4 The lower end of the mixing tank 1 is fixedly connected to two support legs 5. The discharge hole 24, the sealing door 23, the electric telescopic rod 22, the guide telescopic rod 25, and the fixing plate 21 are all located between the two support legs 5. During operation, the support legs 5 support the mixing tank 1, allowing the mixing tank 1 to be detached from the ground, thus facilitating the placement of a receiving box at the bottom of the mixing tank 1 to collect the material discharged from the discharge hole 24.

[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
