[0038] The switching unit is used to switch the operation mode of the stirring unit. The first mode of the stirring unit is used to stir only the raw materials inside the stirring tank 1. The second mode of the stirring unit is to scrape the inner wall of the stirring tank 1 while stirring the raw materials. The top of the stirring tank 1 is also provided with an adjustment component 3 extending into the inside of the stirring tank 1 and connected to the stirring and scraping wall component 2. The adjustment component 3 is used to provide driving force for the operation of the switching unit.

[0040] The driving motor 201 is installed on the top of the stirring tank 1, and the output end of the driving motor 201 penetrates into the interior of the stirring tank 1 and is fixedly connected to the rotating shaft 202. The horizontal straight groove 203 is horizontally opened on the inner side of the rotating shaft 202 and penetrates both sides of the rotating shaft 202.

The bottom of the vertical connecting rod 206 protrudes from the bottom of the rotating shaft 202 and is fixedly connected to the horizontal stirring blade 207.

[0041] The switching unit includes an inclined guide slot 208 and a linkage slide post 209;

[0042] The inclined guide groove 208 is provided at the end surface of the contact position between the vertical connecting rod 206 and the horizontal connecting rod 204 and passes through both ends of the vertical connecting rod 206. A horizontal slide groove is provided at the contact position between the horizontal connecting rod 204 and the vertical connecting rod 206. The horizontal connecting rod 204 is slidably connected to the vertical connecting rod 206 through the horizontal slide groove. The linkage slide column 209 is fixed to the inner side of the horizontal slide groove and is slidably connected to the inclined guide groove 208. During the vertical movement of the vertical connecting rod 206, the inclined guide groove 208 squeezes the linkage slide column 209 to realize the horizontal movement of the vertical stirring blade 205. When the vertical connecting rod 206 moves downward, the horizontal stirring blade 207 is attached to the bottom of the inner wall of the stirring tank 1, and the vertical stirring blade 205 is attached to the side of the inner wall of the stirring tank 1. At this time, the horizontal stirring blade 207 and the inclined guide groove 208 rotate to stir the raw materials and scrape the inner wall of the stirring tank 1. When the vertical connecting rod 206 moves upward, the horizontal stirring blade 207 is separated from the bottom of the inner wall of the stirring tank 1, and the vertical stirring blade 205 is separated from the side of the inner wall of the stirring tank 1. At this time, the horizontal stirring blade 207 and the inclined guide groove 208 rotate only to stir the raw materials;

[0043] The adjusting assembly 3 includes a vertical slide 301, a limit slider 302, an I-shaped ring seat 303, a lifting seat 304, a limit guide column 305, and an electric push rod 306. The vertical slide 301 is opened inside the rotating shaft 202 and passes through both sides of the rotating shaft 202. The vertical slide 301 is located above the horizontal straight groove 203. The limit slider 302 is slidably connected to the inner side of the vertical slide 301. The vertical connecting rod 206 is fixed to the bottom of the limit slider 302. The I-shaped ring seat 303 is sleeved on the outer side of the rotating shaft 202 and It is fixedly connected to the limit slider 302, the lifting seat 304 is sleeved on the outside of the I-shaped ring seat 303, three limit guide pillars 305 are provided and are fixed on the top of the lifting seat 304 in a 270-degree circular distribution, the electric push rod 306 is fixed to the top of the mixing tank 1 and the output end passes through the interior of the mixing tank 1 and is fixedly connected to a limit guide pillar 305, and the other two limit guide pillars 305 pass through the top of the mixing tank 1 and are slidably connected to the mixing tank 1, so as to guide and limit the up and down movement of the lifting seat 304.

[0044] In this embodiment, it should be supplemented that: a feeding port is provided on one side of the top of the stirring kettle 1, the distribution area of ​​the electric push rod 306 and the limiting guide column 305 is far away from the feeding port, and the lifting seat 304 is not a completely disc structure, and the lifting seat 304 will not block the feeding port;

[0045] In the process of stirring the raw materials, the operation mode of the stirring and scraping component 2 can be switched and adjusted by adding the component 3. The two operation modes of the stirring and scraping component 2 are as follows:

[0046] The first mode is simple stirring. At this time, the electric push rod 306 drives the lifting seat 304 to rise to the highest point, and its vertical connecting rod 206 drives the horizontal stirring blade 207 to move up to separate it from the bottom of the inner wall of the stirring tank 1. At the same time, the vertical connecting rod 206 squeezes the linkage sliding column 209 through the inclined guide groove 208 to make it move horizontally. The linkage sliding column 208 drives the horizontal connecting rod 204 to shrink into the horizontal straight groove 203, and the horizontal connecting rod 204 drives the vertical stirring blade 205 away from the side of the inner wall of the stirring tank. When the driving motor 201 is running, the rotating shaft 202 is driven to rotate, and the rotating shaft 202 drives the vertical connecting rod 206, the horizontal stirring blade 207, the horizontal connecting rod 204, the vertical stirring blade 204, and the I-shaped ring seat 303 to rotate synchronously (it should be supplemented that the I-shaped ring seat 303 rotates with the lifting seat 204 as the base, and the lifting seat 204 remains in a non-rotating state). At this time, the rotating horizontal stirring blade 207 and the vertical stirring blade 204 only stir the raw materials, and do not scrape the inner wall of the stirring tank 1;

[0047] The second mode is to scrape the wall while stirring. At this time, the electric push rod 306 pushes the lifting seat 304 downward, and the lifting seat 304 drives the I-shaped ring seat 303, the limit slider 302, the vertical connecting rod 206, and the horizontal stirring blade 207 to move downward synchronously. The horizontal stirring blade 207 is in contact with the bottom of the inner wall of the stirring kettle. At the same time, the vertical connecting rod 206 cooperates with the inclined guide groove 208 and the linkage slide column 209 to make the horizontal connecting rod 204 move toward the outside of the rotating shaft 202. The horizontal connecting rod 204 pushes the vertical stirring blade 205 to move and fit the side of the inner wall of the stirring kettle 1. At this time, when the driving motor 201 drives the vertical stirring blade 205 and the horizontal stirring blade 207 to rotate, not only can the raw materials be stirred, but also the wall scraping operation of the inner wall of the stirring kettle 1 can be achieved;

[0048] Through the coordination of the above multiple parts, the inner wall of the stirring tank 1 can be selectively scraped in the early, middle and late stages of stirring. This can not only avoid the phenomenon of raw materials adhering to the inner wall of the stirring tank 1, but also reduce the contact time between the stirring blade and the inner wall of the stirring tank 1, effectively reduce wear, and then extend the service life of the stirring blade.

[0049] Please refer to Figures 2 to 5 , there are two groups of horizontal connecting rods 204 and vertical stirring blades 205, the two groups of horizontal connecting rods 204 and vertical stirring blades 205 are circumferentially distributed outside the rotating shaft 202, and the two groups of horizontal connecting rods 204 are staggered in the vertical direction, and the inclined guide grooves 208 arranged at the corresponding positions of the vertical connecting rods 206 and the two groups of horizontal connecting rods 204 are inclined in opposite directions;

[0050] A lifting groove is provided inside the driving motor 201 for vertical lifting of the vertical connecting rod 206 , and the lifting groove is connected with the horizontal straight groove 203 and the vertical slide groove 301 . The horizontal stirring blade 207 and the vertical stirring blade 205 are displaced along the circumferential direction.

[0051] In this embodiment: by setting two sets of horizontal connecting rods 204 and vertical stirring blades 205, the force on the rotating shaft 202 is more uniform when rotating;

[0052] The horizontal stirring blades 207 and the vertical stirring blades 205 are staggered along the circumferential direction, so that the vertical movement of the horizontal stirring blades 207 and the horizontal movement of the vertical stirring blades 205 do not interfere with each other.

[0053] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
