[0036] Please see Figure 1 , Figure 2 and Figure 7 A tilting-type mixing machine includes a frame 1, a motor 2, a material cylinder 3, a first limit group 4, a second limit group 5, a transmission pair 6, and a hydraulic cylinder 7.

[0037] The equipment frame 1 has a limiting block 1a, which is used to limit the material cylinder 3 in the future.

[0038] Motor 2 is mounted on equipment frame 1 and is used to drive the rotation of the two stirring shafts on material cylinder 3.

[0039] The two rotating stirring shafts connected in the material cylinder 3 are labeled as: first stirring shaft 3a and second stirring shaft 3b. For ease of illustration, the stirring blades of the first stirring shaft 3a and the second stirring shaft 3b within the material cylinder 3 are not shown in the accompanying drawings.

[0040] The material cylinder 3 is connected to the equipment frame 1, and the connection includes swinging and moving. That is to say, while the swinging is achieved by the hinge between the material cylinder 3 and the equipment frame 1, the axial movement of the material cylinder 3 is not completely restricted.

[0041] The material cylinder 3 can swing around the axis of the first stirring shaft 3a between the following two positions: the first position with the opening facing upward and abutting the limiting block 1a, and the second position with the opening horizontal or tilted downward.

[0042] The material cylinder 3 can also move along the axis of the first stirring shaft 3a between the following two positions: the third position where the first stirring shaft 3a is connected to the output shaft of the motor 2, and the fourth position where the first stirring shaft 3a is separated from the output shaft of the motor 2.

[0043] Please see Figure 1 and Figure 3 In some implementations, both the first stirring shaft 3a and the output shaft of the motor 2 are fixedly connected to a friction disc 2a. The friction disc 2a establishes a transmission between the output shaft of the motor 2 and the first stirring shaft 3a, which is well-suited for designs where the first stirring shaft 3a and the output shaft of the motor 2 can be connected / disconnected by movement.

[0044] During stirring, the material cylinder 3 is maintained at the first and third positions mentioned above. During the process of switching from stirring to discharging, the material cylinder 3 first moves from the third position to the fourth position, and then swings from the first position to the second position.

[0045] Conversely, when discharging material, the material cylinder 3 remains in the second and fourth positions mentioned above. During the process of switching from discharging to stirring, the material cylinder 3 first oscillates from the second position to the first position, and then moves from the fourth position to the third position.

[0046] Please see Figure 1 and Figure 3 In some embodiments, first bearing seats 3c are fixedly connected to both outer walls of the material cylinder 3. The first bearing seats 3c are rotatably connected to the first stirring shaft 3a and the second stirring shaft 3b. More specifically, both ends of the first stirring shaft 3a and the second stirring shaft 3b are stepped. Rolling bearings are installed inside the first bearing seats 3c, with the inner ring end face of the rolling bearing abutting against the shoulder of the first stirring shaft 3a and the second stirring shaft 3b. The two first bearing seats 3c corresponding to the first stirring shaft 3a are also used to connect to the equipment frame 1. More specifically, two second bearing seats 1b are fixedly connected to the equipment frame 1, and sliding bearings for connecting to the first bearing seats 3c are installed inside the second bearing seats 1b.

[0047] The first limit group 4 is set between the material cylinder 3 and the equipment frame 1, and is used to make the material cylinder 3 move first and then swing during the process of switching from stirring to feeding.

[0048] Please see Figure 3 and Figure 5 In some embodiments, the first limiting group 4 includes a first insertion protrusion 4a and a first insertion groove 4b. The first insertion protrusion 4a and the first insertion groove 4b are inserted / separated by moving along the axis of the first stirring shaft 3a. More specifically, the first insertion protrusion 4a is disposed on the outer wall of the material cylinder 3 near the motor 2, and the first insertion groove 4b is disposed on the second bearing seat 1b near the motor 2.

[0049] The second limit group 5 is set between the material cylinder 3 and the equipment frame 1, and is used to make the material cylinder 3 swing first and then move during the process of switching from feeding to stirring.

[0050] Please see Figure 3 and Figure 4In some embodiments, the second limiting group 5 includes a second insertion protrusion 5a and a second insertion groove 5b. The end of the second insertion protrusion 5a has a stop. The second insertion groove 5b is arc-shaped, with its center located on the axis of the first stirring shaft 3a. The second insertion groove 5b includes a first section 5b-1 for the stop to enter / exit and a second section 5b-2 for restricting the stop to exit. That is, the cross-section of the second section 5b-2 is convex, and the cross-section of the first section 5b-1 is U-shaped, with a width equal to the wider portion of the second section 5b-2. More specifically, the second insertion protrusion 5a is located on the outer wall of the material cylinder 3 away from the motor 2, and the second insertion groove 5b is located on the second bearing seat 1b away from the motor 2.

[0051] During the process of material cylinder 3 switching from stirring to feeding: material cylinder 3 moves first, the stop block enters the first section 5b-1, the first insertion protrusion 4a leaves the first insertion groove 4b, when the stop block abuts against the inner wall of the plane of the second insertion groove 5b, the first insertion protrusion 4a and the first insertion groove 4b separate; material cylinder 3 then swings, and the stop block enters the second section 5b-2.

[0052] During the process of material cylinder 3 switching from feeding to stirring: material cylinder 3 first swings, and when material cylinder 3 abuts against limit block 1a, the stop block enters the first section 5b-1; material cylinder 3 then moves, the first insertion protrusion 4a enters the first insertion groove 4b, and the stop block leaves the first section 5b-1.

[0053] The transmission pair 6 is located between the first stirring shaft 3a and the second stirring shaft 3b, and is used to make the two rotate in opposite directions.

[0054] Please see Figure 1 and Figure 7 In some embodiments, the transmission pair 6 is a gear pair, including a first gear 6a and a second gear 6b. The first gear 6a and the second gear 6b ​​are fixedly connected to the first stirring shaft 3a and the second stirring shaft 3b, respectively. Depending on the speed ratio of the first stirring shaft 3a and the second stirring shaft 3b, the number of teeth on the first gear 6a and the second gear 6b ​​can be the same or different.

[0055] Please see Figure 8 The cylinder body of hydraulic cylinder 7 is connected to one of the equipment frame 1 and the material cylinder 3, and the piston rod is connected to the other. More specifically, hydraulic cylinder 7 and material cylinder 3 can be connected by a universal joint 7a, and hydraulic cylinder 7 and equipment frame 1 can be connected by a ball joint bearing 7b.

[0056] Please see Figure 1 When the material cylinder 3 is stirring, in a top-down view, the hydraulic cylinder 7 is biased towards the side of the second limit group 5. During the process of the material cylinder 3 switching from stirring to discharging, the piston rod extends; during the process of the material cylinder 3 switching from discharging to stirring, the piston rod retracts.
