[0057] The tank body is also provided with a scraper assembly for cleaning the filter plate 18, which includes a third telescopic drive device 19 and a push plate 20.

[0058] In the plant extraction device of Example 2, protective components are symmetrically provided on both sides of the outer wall of the tank body, and the protective components include a buffer telescopic rod 25, a buffer spring 26, a protective plate 27 and a buffer pad 28.

The buffer pad is installed on the protective plate. The buffer telescopic rod is provided with a buffer spring 26 to play a buffering role.

[0059] In the plant extraction device of Example 2, a cleaning nozzle 8 is fixedly connected to one side of the tank top 32, a manhole 9 is also provided on the tank top 32, an electric heater 10 is provided on the tank bottom, and a control switch is also provided on the side wall of the tank body, such as Figure 6 As shown, the control switch is electrically connected to the first telescopic drive device 12, the second telescopic drive device 16 and the third telescopic drive device 19;

[0061] Working principle:

[0062] When in use, the second drive motor 24 is started. Due to the anti-blocking component, the second drive motor 24 drives the second rotating shaft 22 to rotate, and the rotation of the rotating shaft drives the dredging plate 23 to rotate. The delivered raw materials are continuously dredged by the dredging plate 23, and the materials are smoothly added to the tank body from the feed port 2. The first drive motor 3 is started, and the first drive motor 3 rotates to drive the first rotating shaft 6 to rotate, and the first rotating shaft 6 rotates to drive the stirring blade 7 to rotate to stir the raw materials in the tank body. When it is necessary to clean the inner wall of the tank body, the first drive motor 3 is stopped first, the first telescopic drive device 12 is started to extend and drive the transmission rod 13 to move into the transmission hole 15 in the transmission disk 14, the first drive motor 3 is started to rotate to drive the first rotating shaft 6 to rotate, and the first rotating shaft 6 rotates to drive the cleaning component to rotate along the slot 29 provided on the inner wall of the tank body, so that the brush head 17 rotates along the inner wall of the tank body to clean the inner wall of the tank body, and at the same time, the second telescopic drive device 16 is controlled to drive the brush head 17 to move along the Z-axis direction to achieve cleaning of the inner wall of the tank body at different heights. After the brush head is cleaned, the inner wall of the tank body is further cleaned by the cleaning nozzle 8, and the washed residue falls on the filter hole plate 18. At this time, the third telescopic drive device 19 is started, and the push plate 20 pushes the residue on the filter hole plate 18 to the second residue outlet 21 under the action of the third telescopic drive device 19, and the residue is discharged from the residue outlet 21. When it is not necessary to clean the inner wall of the tank body and stir the material in the tank body, the first telescopic drive device 12 is controlled to contract and drive the transmission rod 13 to move out of the transmission hole 15, thereby releasing the transmission between the transmission rod 13 and the transmission hole 15, so that the brush head no longer rotates.

[0063] By arranging protective components on both sides of the tank body, a buffering and protective effect can be achieved against external impacts. When the protective plate is impacted and moved toward the tank body, the buffer springs can further improve the buffering effect and reduce the impact of the impact.

[0064] Comparative Example 1

[0065] Comparative Example 1 Plant Extraction Device Figure 7 As shown, compared with Example 1, the difference is that: the cleaning component of Example 1 includes a rotating arm 34, a second telescopic drive device 16 and a brush head 17, one end of the rotating arm is fixedly connected to the first rotating shaft 6, and the other end is fixedly connected to the second telescopic drive device, the movable end of the second telescopic drive device 16 is fixedly connected to the brush head 17, the second telescopic drive device rotates under the drive of the first rotating shaft 6, thereby driving the brush head 17 to rotate and realize the cleaning of the inner wall of the can body, and the brush head 17 moves along the Z-axis direction under the drive of the second telescopic drive device 16 to realize the cleaning of the inner wall of the can body.

[0066] The plant extraction devices of Example 1 and Comparative Example 1 were used for extraction in the same process. The service life of the brush head, power consumption and cleaning effect are shown in Table 1.

[0067] Table 1 Comparison of the operation of the plant extraction device of Example 1 and Comparative Example 1

[0068]

[0069] It can be seen from Table 1 that, compared with Comparative Example 1, the brush head of the plant extraction device of the utility model has a long service life, low energy consumption and good cleaning effect.

[0070] In summary, the utility model can make the brush head at the lower end of the rotating ring fit closely with the inner wall of the can body by opening a slot on the inner wall of the can body and slidingly cooperating with the slot through the rotating ring, thereby improving the cleaning effect. At the same time, the second telescopic drive device can drive the brush head to move up and down along the Z-axis direction and the cleaning component to move circumferentially under the drive of the first rotating shaft, thereby increasing the cleaning area, achieving all-round deep cleaning of the inner wall of the can body, and improving the quality and efficiency of plant extraction. In addition, the first telescopic drive device can realize the connection and separation of the cleaning component and the first rotating shaft, and the cleaning time can be flexibly selected according to needs, thereby avoiding the brush head from rotating with the first rotating shaft all the time, effectively reducing the loss of the brush head, and greatly reducing power consumption and production costs.
