Through the slider 53 and the slide groove 23, the horizontal plate 3 moves along the length direction of the horizontal groove 21, thereby driving the stirring block 4 to move synchronously, thereby adjusting the stirring range of the stirring block 4, thereby improving the stirring effect, and then improving the processing quality of the raw materials.

[0041] Reference Figure 3 and Figure 4 , the top of each connection groove 31 is equipped with a rotating mechanism 6, a lifting plate 71, a lifting block 72 and a limiter 8. The rotating mechanism 6 includes a rotating spring 61 and a baffle 62. The vertically arranged rotating spring 61 is located at the top of the stirring block 4. One end of the rotating spring 61 is fixedly connected to the top of the connection groove 31, and the other end of the rotating spring 61 is fixedly connected to the side wall of the stirring block 4. The vertically arranged baffle 62 is located on one side of the stirring block 4, and the top of the baffle 62 is fixedly connected to the bottom of the horizontal plate 3. One end of the vertically arranged lifting plate 71 vertically passes through the horizontal plate 3 and then extends to the top of the stirring block 4. The bottom of the lifting plate 71 is hinged to the top of the lifting block 72. A limit hole 73 is arranged on the lifting plate 71, and the limit hole 73 passes through the lifting plate 71 along the length direction of the support plate 2.

[0042] The lifting block 72 is T-shaped, and the bottom of the lifting block 72 is located in the rotating groove 41 and contacts the side wall of the rotating groove 41. The limiting member 8 includes a limiting cylinder 81 and a limiting block 82. The horizontally arranged limiting cylinder 81 is located on the cross plate 3 and is fixedly connected to the top of the cross plate 3.

Each ball 74 is rotatably connected to the side wall of the limiting block 82, and each ball 74 is used to contact the side wall of the limiting hole 73.

[0043] When the horizontal plate 3 moves in the direction away from the rotating shaft 12 until the stirring block 4 is separated from the horizontal groove 21, the stirring block 4 is transformed from a horizontal setting to a vertical setting driven by the gravity potential energy of the stirring block 4 itself, and the side wall of the stirring block 4 contacts the baffle 62 through the elastic potential energy of the rotating spring 61, thereby limiting the stirring block 4, so that when the driving motor 11 rotates, the stirring block 4 is always set vertically, thereby stirring the raw materials in the kettle body 1. When the horizontal plate 3 moves in the direction close to the rotating shaft 12, the staff lifts and lowers the lifting plate 71, so that the stirring block 4 is transformed from a vertical setting to a horizontal setting through the lifting block 72 and the rotating groove 41, at this time, the rotating spring 61 is compressed, and at the same time, the staff starts the limit cylinder 81, and the piston rod of the limit cylinder 81 is extended and retracted to drive the limit block 82 to move synchronously, so that the side wall of the limit block 82 contacts the side wall of the ball 74, thereby limiting the lifting plate 71, improving the stability of the lifting plate 71, and facilitating the horizontal plate 3 to move in the direction close to the rotating shaft 12.

[0044] The implementation principle of the reactor with a stirring device in the embodiment of the present application is as follows: when the staff transfers the raw materials into the reactor body 1, the staff starts the driving motor 11, and the output shaft of the driving motor 11 rotates to drive the support plate 2 and the horizontal plate 3 to rotate synchronously, thereby driving the stirring block 4 to rotate synchronously, thereby stirring the raw materials in the reactor body 1. The staff starts the push cylinder 51, and the piston rod of the push cylinder 51 is extended and retracted to drive the vertical plate 52 to move synchronously. When the vertical plate 52 moves in a direction away from the rotating shaft 12, the horizontal plate 3 moves in the horizontal groove 21 in a direction away from the rotating shaft 12 through the slider 53 and the slide groove 23, so that the stirring block 4 on the side close to the rotating shaft 12 is converted from a horizontal setting to a vertical setting, and the elastic potential energy of the rotating spring 61 is used to improve the stability of the stirring block 4 on the side close to the rotating shaft 12, and at the same time, the stirring range of the stirring block 4 is expanded, so that the raw materials in the reactor body 1 are mixed more evenly, thereby improving the processing quality.

[0045] When the vertical plate 52 moves in the direction close to the rotating shaft 12, the staff adjusts the lifting plate 71 so that the lifting plate 71 moves in the vertical upward direction, thereby driving the stirring block 4 to rotate synchronously until the stirring block 4 is converted from a vertical setting to a horizontal setting. At this time, the staff starts the limit cylinder 81, and the piston rod of the limit cylinder 81 is extended and retracted to drive the limit block 82 to move synchronously until the side wall of the limit block 82 contacts the side wall of the ball 74, thereby limiting the lifting plate 71, thereby facilitating the movement of the cross plate 3 in the direction close to the rotating shaft 12.

Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
