A valve is installed inside the discharge pipe 5 (the valve is not shown in the figure). The feed pipe 3 is provided to facilitate the feeding process, and the discharge pipe 5 is provided to facilitate the discharge process. The stirring assembly 7 is disposed between the kettle body 1 and the upper cover 2, and the stirring assembly 7 is installed with the upper cover 2; A first adjusting component 8 is disposed in the kettle body 1, and the first adjusting component 8 is connected to the stirring component 7; The second regulating component 9 is connected between the interior of the kettle body 1 and the stirring component 7; The scraping assembly 10 is connected to the second adjusting assembly 9 and is in contact with the inner wall of the kettle body 1 .
[0023] The stirring assembly 7 comprises: The motor 71 is fixedly mounted on the top of the upper cover 1. The output end of the motor 71 penetrates the top of the upper cover 1 and extends to be fixedly mounted on the top of the connecting shaft 72. The top surface of the disk 73 is fixedly mounted on the lower end of the connecting shaft 72. The top surface of the disk 73 is provided with an arc-shaped opening 74. The number of the arc-shaped openings 74 is three. The three arc-shaped openings 74 are evenly spaced on the top surface of the disk 73. An arc-shaped column 76 is fixedly mounted on the inner wall of each arc-shaped opening 74. The connecting block 75 is slidably mounted on the outer wall of the arc column 76; The upper end of the connecting column 77 is fixedly installed with the lower end of the connecting block 75, and the outer wall sliding sleeve of the connecting column 77 is provided with a hollow column 78, and the connecting column 77 is connected to the hollow column 78 through the second adjustment component 9, and the outer wall of the hollow column 78 is fixedly installed with a stirring blade 79.
[0024] In the specific implementation process, the connecting shaft 72 is rotated by starting the motor 71, and the disc 73 can be rotated when the connecting shaft 72 rotates. Due to the setting of the connecting block 75 and the connection between the connecting column 77 and the hollow column 78 through the second adjustment component 9, the hollow column 78 can finally drive the stirring blade 79 to rotate, and the material in the kettle body 1 can be mixed and stirred when the stirring blade 9 rotates.
[0025] Implementation 2 On the basis of the above embodiment, the first adjustment component 8 includes: The auxiliary cover 81 is arranged at the outer position of the disc 73, the inner wall of the lower end of the auxiliary cover 81 is inclined, and the outer wall of the connecting column 77 is slidably arranged; The wedge-shaped column 82 is fixedly sleeved on the outer wall of the connecting shaft 72, and the bottom surface of the connecting shaft 72 is in contact with the top surface of the auxiliary cover 81. Here, the surfaces where the wedge-shaped column 82 and the auxiliary cover 81 contact each other are both inclined. By setting the surfaces where the wedge-shaped column 82 and the auxiliary cover 81 contact each other as inclined surfaces, it is convenient for the wedge-shaped column 82 to squeeze the auxiliary cover 81 during the rotation process, so that the position of the auxiliary cover 81 can be moved; A large spring 83 is disposed outside the connecting shaft 72, and the top of the large spring 83 is fixedly mounted to the top of the inner wall of the upper cover 2, and the top of the large spring 83 is fixedly mounted to the top surface of the auxiliary cover 81; The curved spring 84 is sleeved on the outer wall of the arc column 76 , one end of the curved spring 84 is fixedly mounted on the inner wall of the arc opening 74 , and the other end of the curved spring 84 is fixedly mounted on the surface of the connecting block 75 .
[0026] During the specific implementation process, the rotation of the connecting shaft 72 can drive the wedge-shaped column 82 to rotate together. Since the contact surface between the wedge-shaped column 82 and the auxiliary cover 81 is set as an inclined surface, the auxiliary cover 81 can be moved when the wedge-shaped column 82 rotates. At the same time, the auxiliary cover 81 can be moved up and down reciprocatingly under the setting of the large spring 83, so that the connecting column 77 can be squeezed. Finally, the stirring angle of the stirring blade 79 can be changed. Under the setting of the bent spring 84, the angle of the stirring blade 79 can be repeatedly changed to change the stirring range. Example 3
[0027] On the basis of the above embodiment, the second adjustment component 9 includes: The limiting block 91 is slidably arranged at both ends with the inner rectangular groove 92 opened on the inner wall of the hollow column 78, the top of the limiting block 91 is fixedly installed with the bottom end of the connecting column 77, the bottom surface of the limiting block 91 is fixedly installed with a first spring 93, and the bottom end of the first spring 93 is fixedly installed with the bottom of the inner wall of the hollow column 78; The outer wall of the annular plate 95 is slidably arranged in the annular groove opened in the inner wall of the kettle body 1, and an L-shaped rod 94 is arranged between the annular plate 95 and the hollow column 78. One end of the L-shaped rod 94 is slidably arranged in the outer rectangular groove 96 opened on the top surface of the annular plate 95, and the other end of the L-shaped rod 94 is fixedly arranged on the hollow column 78.
[0028] In the specific implementation process, the L-shaped rod 94 can be moved from the outer rectangular groove 96 during the change of the angle of the stirring blade 79. Since the connecting column 77 and the hollow column 78 are arranged for sliding, the hollow column 78 will be subjected to an upward squeezing force when the L-shaped rod 96 moves. Then, under the setting of the first spring 93, the hollow column 78 can be moved back and forth up and down, and then the stirring blade 79 can be changed to stir reciprocate up and down, thereby changing the stirring range again. Example 4
[0029] On the basis of the above-mentioned embodiment, the scraping assembly 10 comprises: The arc scraper 1001 has one side in contact with the inner wall of the kettle body 1, and the bottom of the arc scraper 1001 is fixedly installed with the top surface of the annular plate 95; The elastic rubber ring 1002 is slidably disposed on the inner wall of the annular groove, and the bottom of the elastic rubber ring 1002 is disposed in contact with the bottom of the inner wall of the annular groove, and the top of the elastic rubber ring 1002 is fixedly disposed on the bottom surface of the annular plate 95 .
[0030] In this embodiment, the interior of the elastic rubber ring 1002 is a hollow space, and a second spring 1003 is fixedly installed inside the elastic rubber ring 1002 .
[0031] In the specific implementation process, due to the movement of the L-shaped rod 94, the annular plate 95 can also move downward, and the arc scraper 1001 can also move downward during the rotation process. In particular, the elastic rubber ring 1002 and the second spring 1003 can realize the up and down reciprocating movement of the arc scraper 1001, thereby strengthening the scraping treatment of the inner wall of the kettle body 1.
[0032] Working principle: the material to be stirred is fed into the kettle body 1 through the feed pipe 3, and then the motor 71 is started to rotate the connecting shaft 72, and the disc 73 is rotated when the connecting shaft 72 rotates, and then the connecting block 75 drives the connecting column 77 to rotate. Due to the setting of the limit block 91, the rotation of the connecting column 77 can drive the hollow column 78 to rotate, and the rotation of the hollow column 78 can drive the stirring blade 79 to rotate, so as to achieve the purpose of stirring and mixing. When the connecting shaft 72 rotates, the wedge-shaped column 82 can be rotated, and then the auxiliary cover 81 can be squeezed. Due to the setting of the large spring 83, the auxiliary cover 81 can be reciprocated up and down. During the downward movement of the auxiliary cover 81, the three connecting columns 77 can be squeezed to make the three connecting columns 77 move inward, and then The angle of the hollow column 78 can be changed, and finally the stirring range of the stirring blade 79 can be changed. When the hollow column 78 moves inward, the L-shaped rod 94 will move inward during the rotation, and then the hollow column 78 can be moved upward. Under the setting of the first spring 93, the hollow column 78 can drive the stirring blade 79 to reciprocate up and down, and the stirring range of the stirring blade 79 can be changed again. During the rotation of the L-shaped rod 94, the annular plate 95 can be rotated, and the annular plate 95 can also move downward. Finally, under the setting of the elastic rubber ring 1002 and the second spring 1003, the arc scraper 1001 can be reciprocated up and down during the rotation process, so that the cleaning of the inner wall of the kettle body 1 can be strengthened to avoid the adhesion of materials and waste of material resources.
