Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0016] like Figure 1-6As shown, this utility model provides a technical solution: a tilting mixer, including a fixed frame 1 and a mixing drum 2. Support plates 4 are fixedly installed on both sides of the inner wall of the fixed frame 1. A motor 3 and a motor 7 are respectively fixedly installed at the top of the two support plates 4. The mixing drum 2 is connected to the motor 7 via a transmission connection. A rotating shaft 5 is fixedly installed at the output end of the motor 3. The rotating shaft 5 passes through one side of the mixing drum 2 and is rotatably connected to the mixing drum 2 via a bearing. A bushing 6 is sleeved on the outer wall of the rotating shaft 5, and the bushing 6 is slidably connected to the outer wall of the rotating shaft 5. Next, a reciprocating screw 8 is fixedly installed on one side of the inner wall of the mixing tank 2. The reciprocating screw 8 movably passes through one end of the bushing 6. A threaded sleeve block 9 is fixedly installed on the inner wall of the bushing 6. The threaded sleeve block 9 is threaded onto the outer wall of the reciprocating screw 8. A stirring plate 10 is hinged to the outer wall of the bushing 6. An L-shaped support plate 11 is fixedly installed on the outer wall of the rotating shaft 5. A rotating groove 12 is opened on the L-shaped support plate 11. The stirring plate 10 movably passes through the rotating groove 12. A pin 13 is fixedly installed on the inner wall of the rotating groove 12. A shaft groove 14 is opened on the stirring plate 10. The pin 13 movably passes through the shaft groove 14.
[0017] Specifically, in the above technical solution, when the tilting mixer is in use, motor 3 and motor 7 are started. Motor 7 drives the mixing drum 2 to rotate via shaft 23. Motor 3 drives shaft 5 to rotate. Shaft 5 drives bushing 6 to rotate via limit slide plate 15. Bushing 6 drives stirring plate 10 to rotate. Mixing drum 2 drives reciprocating screw 8 to rotate, causing reciprocating screw 8 and bushing 6 to rotate in opposite directions. Bushing 6 drives threaded sleeve block 9 to rotate, causing threaded sleeve block 9 to drive bushing 6 to move left and right reciprocally under the action of reciprocating screw 8. Bushing 6 drives the bottom end of stirring plate 10 to move left and right reciprocally, causing stirring plate 10 to rotate left and right, increasing the stirring range of stirring plate 10, thereby greatly improving the mixing quality of materials by stirring plate 10 and improving mixing efficiency. This solves the problem in existing tilting mixers where the angle of stirring plate 10 is fixed, resulting in a fixed stirring range of stirring plate 10, making it difficult to quickly stir and mix materials, thus affecting mixing efficiency.
[0018] Furthermore, there are several stirring plates 10, and the pins 13 are matched with the shaft grooves 14; By setting the pin 13 and the shaft groove 14, the stirring plate 10 can be limited so that the stirring plate 10 can rotate in a fixed position.

[0020] Furthermore, a limiting slide plate 15 is fixedly installed on the inner wall of the bushing 6, and a limiting groove 16 is opened on the outer wall of the rotating shaft 5, and the limiting slide plate 15 and the limiting groove 16 are slidably connected. By setting a limiting slide plate 15 and a limiting slide groove 16, the rotating shaft 5 can drive the bushing 6 to rotate through the limiting slide plate 15.
[0021] Furthermore, the bottom of the mixing tank 2 is provided with an inlet / outlet 19, a blocking plate 17 is tightly engaged in the inlet / outlet 19, a cover plate 18 is fixedly installed on the outer wall of the blocking plate 17, the cover plate 18 is sleeved on the outer wall of the mixing tank 2, and the cover plate 18 is detachably connected to the mixing tank 2. The inlet and outlet 19 can be sealed and covered by the blocking plate 17 and the cover plate 17.
[0022] Furthermore, support shafts 20 are fixedly installed on both sides of the inner wall of the fixed frame 1, and support ring grooves 21 are opened on both sides of the mixing tank 2. The support shafts 20 are slidably connected to the inner wall of the support ring grooves 21. A wall pad 22 is fixedly installed on the inner wall of the support ring grooves 21. The wall pad 22 is in contact with the outer wall surface of the support shafts 20. The material of the wall pad 22 is Teflon. The support shaft 20 and the support ring groove 21 provide support for the mixing tank 2 and improve its stability during rotation. The wall pad 22 reduces friction between the support shaft 20 and the support ring groove 21, thus reducing wear.
