[0031] Exemplarily, referring to Figures 1-3 And Figure 7 As shown, it further includes barrel 300, the bottom of barrel 300 is rotatably connected with stirring shaft 301, the bottom end of stirring shaft 301 extends to the outside of barrel 300, and the end portion is fixedly connected with rotating handle 302, the top end of stirring shaft 301 extends to the inside of barrel 300, and the end portion is fixedly connected with stirring blade 303, and four connecting columns 304 are fixed on the side surface of barrel 300.

[0032] In the technical scheme, when the axle 206 at both ends of the axle clamp fixing piece 205 is located at both sides of the rotating handle 302, the rotating motor 203 drives the axle clamp fixing piece 205 to rotate, and the axle 206 can clamp the rotating handle 302, at this time, the axle clamp fixing piece 205 drives the rotating handle 302 to rotate together, and further drives the stirring shaft 301 and the stirring blade 303 to rotate, so that the material in the barrel 300 can be stirred.

[0033] Exemplarily, referring to Figures 1-3As shown, the device further comprises a barrel positioning mechanism 400, which comprises a column 401 arranged around the jacking mechanism 100, a beam bracket 402 fixed on the column 401, a shelf side guide rod 403 fixed on one side of the beam bracket 402, and a shelf front and rear guide plate 404 fixed on both ends of the beam bracket 402. The beam bracket 402 is arranged corresponding to the connecting column 304.

[0034] In this technical solution, the two ends of the two beam brackets 402 support four connecting columns 304 respectively, ensuring that the barrel 300 can be arranged directly above the rotating mechanism 200. By arranging the shelf side guide rod 403 and the shelf front and rear guide plate 404, the barrel 300 can be limited to prevent movement during stirring.

[0038] In this technical solution, the spring sleeve 207 can limit the spring 208. When the clamping shaft 206 is located directly below the rotating handle 302 during jacking, the clamping shaft 206 is extruded downward by the rotating handle 302. At this time, the check ring on the clamping shaft 206 can compress the spring 208 downward. When the clamping shaft 206 rotates out of the position of the rotating handle 302, the spring 208 can pop out the clamping shaft 206.

The rotating shaft of the rotating motor 203, the clamping shaft fixing member 205, and the central axis of the stirring shaft 301 are coincident.

[0042] In this technical solution, the jacking mechanism 100 can jacks up the rotating mechanism 200 to the rotating handle 302 at the bottom of the barrel 300. The rotating mechanism 200 can drive the rotating handle 302 to rotate, and in turn drive the stirring shaft 301 and the stirring blade 303 to rotate, so as to realize the stirring of the material in the barrel 300. The rotating shaft of the rotating motor 203, the clamping shaft fixing member 205, and the central axis of the stirring shaft 301 are coincident, which can make the rotating motion more stable.

[0043] For example, referring to Figure 4 As shown, two air cylinders 102 are arranged at opposite corners of the support seat 101.

[0044] In this technical solution, the two air cylinders 102 can stably jack up the rotating mechanism 200 upward.

[0045] For example, referring to Figure 5 As shown, four guide shafts 202 are arranged in a rectangular shape.

[0046] In this technical solution, the guide shaft 202 can provide guidance for the up-and-down movement of the rotating mechanism 200, and also improve the stability of the up-and-down movement of the rotating mechanism 200.

[0047] Working principle: when the handle rotating mechanism is used, firstly, the air cylinder 102 is started, the fixed platform 201 is lifted upward until the clamping shaft 206 is located on both sides of the rotating handle 302 or the clamping shaft 206 is contracted downward due to the blocking of the rotating handle 302, then the rotating motor 203 is started, the rotating motor 203 drives the clamping shaft fixing part 205 to rotate, finally the clamping shaft 206 clamps the rotating handle 302 and drives it to rotate together, the rotating handle 302 drives the stirring shaft 301 and the stirring blade 303 to rotate together, realizing the stirring of the material in the barrel 300. The handle rotating mechanism has advanced design, compact structure and convenient use, the rotating mechanism 200 can be lifted by setting the air cylinder 102, the clamping shaft 206 can be telescopic by setting the spring sleeve 207 and the spring 208, when the two clamping shafts 206 are located on both sides of the rotating handle 302, the rotating motor 203 drives the clamping shaft fixing part 205 to rotate, the two clamping shafts 206 can clamp the rotating handle 302 and drive it to rotate together, when the two clamping shafts 206 are located directly below the rotating handle 302, the spring 208 is compressed when lifting, the clamping shaft 206 is contracted, then it is rotated, the clamping shaft 206 is popped out after rotating out of the position of the rotating handle 302, that is, it can clamp the rotating handle 302, without considering the position of the rotating handle 302, the rotating stirring can be carried out and the rotating handle 302 can be rotated to the specified position, which is beneficial to reduce the cost, improve the operation efficiency, has high fault tolerance and realizes simple and convenient.
