Shaft 1 30 is rotatably connected to the top inner wall of box body 2 11, and motor 20 provides power for the entire driving mechanism.

[0023] See also Figure 1-4The present invention provides a technical solution: the bevel gear three 23 and the rotating shaft two are both sleeved on the outer arc wall of the rotating shaft one 30, and the end of the rotating shaft two away from the bevel gear three 23 passes through the top of the box body one 10, and the end of the outer arc wall of the rotating shaft one 30 located in the box body one 10 is sleeved with a sleeve shaft one 31 and a sleeve shaft two 32 in sequence, the sleeve shaft one 31 is located between the rotating shaft two and the sleeve shaft two 32, the sleeve shaft one 31 and the rotating shaft two are clamped with each other, the sleeve shaft one 31 and the sleeve shaft two 32 abut against each other, a fixing bolt is fixedly connected at the center of the bottom of the rotating shaft one 30, and a fixing cover 33 is threadedly connected to the outer side of the fixing bolt, and the fixing cover 33 and the sleeve shaft two 32 abut against each other.

[0024] It should be noted that: sleeve shaft 1 31 and sleeve shaft 2 32 are both located in box body 10, and the end of rotating shaft 2 away from bevel gear 3 23 is also located in box body 10. During installation, sleeve shaft 1 31 is first sleeved on rotating shaft 1 30 and then sleeve shaft 2 32 is sleeved on sleeve shaft 2 32 so that the two are in contact with each other. Furthermore, a side wall of sleeve shaft 1 31 close to sleeve shaft 2 32 is embedded with a plurality of balls distributed in a circular array, and a side wall of sleeve shaft 2 32 close to sleeve shaft 1 31 is provided with an annular rolling groove, and the balls roll in the rolling groove to reduce the friction when sleeve shaft 1 31 and sleeve shaft 2 32 rotate relative to each other.

[0025] See also Figure 1-4 The present invention provides a technical solution: the cross-sectional radius of a section of the rotating shaft 1 30 located inside the sleeve shaft 2 32 is larger than the cross-sectional radius of a section of the rotating shaft 1 30 located inside the sleeve shaft 1 31, and there is a cliff-like transition between the two ends. A spline is provided on the inner arc wall of the sleeve shaft 2 32, and a spline sleeve adapted thereto is provided at a corresponding position on the outer arc wall of the rotating shaft 1 30.

An auxiliary stirring mechanism is fixedly connected to the outer arc wall of the sleeve shaft 1 31.

[0026] It should be noted that: the splines on the inner arc wall of sleeve shaft 2 32 and the spline sleeve on the outer arc wall of rotating shaft 1 30 allow sleeve shaft 2 32 to slide relative to rotating shaft 1 30, while rotating shaft 1 30 can also transmit torque to sleeve shaft 2 32. The inner arc wall of sleeve shaft 1 31 does not contact the spline sleeve on the outer arc wall of rotating shaft 1 30. Sleeve shaft 1 31 is inserted into slot 1 on rotating shaft 2 through a clamping block to transmit torque. At the same time, due to the rotational abutment of sleeve shaft 2 32, sleeve shaft 1 31 will not fall off. The fixing cover 33 protects sleeve shaft 1 31 and sleeve shaft 2 32 as a whole to prevent them from falling off.

[0027] See also Figure 1-4The present invention provides a technical solution: an auxiliary stirring mechanism is fixedly connected to the top of the outer arc wall of the sleeve shaft 1 31, and cutting stirring blades 24 are fixedly connected to the bottom end of the outer arc wall of the sleeve shaft 1 31 and the outer arc wall of the sleeve shaft 2 32. The auxiliary stirring mechanism includes two symmetrically arranged limiting sleeve shafts 34 fixedly connected to the outer arc wall of the sleeve shaft 1 31, and the axial direction of the limiting sleeve shaft 34 is perpendicular to the axial direction of the sleeve shaft 1 31. The side of the limiting sleeve shaft 34 away from the sleeve shaft 1 31 is rotatably connected to a horizontal rotating rod 40, and the end of the rotating rod 40 away from the sleeve shaft 1 31 is fixedly connected to a bevel gear 42, and the bottoms of the two bevel gears 42 are meshedly connected to the same annular gear disk 41, and the annular gear disk 41 is fixedly connected to the inner arc wall of the box body 10.

[0028] It should be noted that the limiting sleeve 34 does not penetrate the inner side of the sleeve 1 31 , and the rotating rod 40 is sleeved in the limiting sleeve 34 . When the sleeve 1 31 rotates, the rotating rod 40 drives the bevel gear 42 to rotate. Due to the meshing of the bevel gear 42 and the annular gear 41 , the bevel gear 42 rotates, thereby causing the stirring rod 43 on the rotating rod 40 to rotate.

[0029] See also Figure 1-4 The present invention provides a technical solution: a plurality of stirring rods 43 are fixedly connected to the outer arc wall of the rotating rod 40, and the plurality of stirring rods 43 are staggeredly distributed about the axial direction of the rotating rod 40. A protective plate 44 is fixedly connected to the inner arc wall of the box body 10 at the position of the annular gear disk 41. The protective plate 44 is a hollow structure. The annular gear disk 41 and the bevel gear 42 are both located in the protective plate 44. An annular channel 1 is opened at the center of the inner arc wall of the protective plate 44 and penetrates along its radial direction. The end of the rotating rod 40 away from the sleeve shaft 31 is slidably connected in the channel 1.

[0030] It should be noted that: in a possible embodiment, a cutting knife is provided on the side of the outer arc wall of the stirring rod 43 facing the rotation direction to assist in cutting and crushing the rubber, and at the same time, it can assist in stirring the easily suspended material on the top of the stirring material to avoid stratification.

[0031] See also Figure 1-4 The present invention provides a technical solution: a sealing plate is rotatably connected in channel 1 on the protection plate 44, the shape of the sealing plate is adapted to channel 1, and a channel 2 is radially penetrated on a side wall of the sealing plate close to the sleeve shaft 1 31, and the end of the rotating rod 40 away from the sleeve shaft 1 31 penetrates into channel 2.

[0032] It should be noted that the protection plate 44 is used to prevent the stirring material from accidentally entering the teeth of the annular gear disk 41 and affecting the meshing of the bevel gear four 42. At the same time, the sealing plate can rotate along channel two, and channel one provides space and trajectory limitations for the rotation of the rotating rod 40. In addition, the sealing plate can intercept the material from entering channel one. When the rotating rod 40 rotates, the sealing plate will be driven to rotate synchronously in channel two.

[0033] See also Figure 1-4 The present invention provides a technical solution: a feed port is provided on the outer arc wall of the box body 10, and a discharge port is provided at the bottom of the box body 10.

[0034] It should be noted that solenoid valves are provided in both the feed port and the discharge port.

[0035] Working principle: The motor 20 drives the bevel gear 1 21 to mesh with the bevel gear 2 22 and the bevel gear 3 23 to realize coaxial reverse rotation. The bevel gear 2 22 drives the rotating shaft 1 30 and the sleeve shaft 2 32. The bevel gear 3 23 drives the rotating shaft 2 and the sleeve shaft 1 31. The sleeve shaft 1 31 drives the auxiliary stirring mechanism and several groups of cutting and stirring blades 24 therein. The sleeve shaft 2 32 drives the remaining several groups of cutting and stirring blades 24. When the sleeve shaft 31 rotates, the rotating rod 40 is sleeved in the limiting sleeve shaft 34, so that the rotating rod 40 drives the bevel gear 42 to rotate. Due to the meshing of the bevel gear 42 and the annular gear plate 41, the bevel gear 42 rotates on itself, and the bevel gear 42 reversely drives the rotating rod 40 to rotate, thereby rotating the stirring rod 43 on the rotating rod 40, so as to assist in stirring the easily suspended material on the top of the stirring material to avoid stratification.
