DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] The utility model provides Figure 1-6 A stirring device for fermentation is shown, comprising:

[0027] A stirring kettle body 1 is provided with a servo motor 2 on the top, and the output end of the servo motor 2 is connected to a main shaft 201;

[0028] The connecting cylinder 3 is fixedly sleeved on the outside of the main shaft 201. A plurality of stirring blades 4 are fixedly installed on the outer wall of the connecting cylinder 3. When the raw materials inside the stirring kettle body 1 need to be stirred, the main shaft 201 is driven to rotate clockwise by the operation of the servo motor 2, so that the connecting cylinder 3 drives the stirring blades 4 to rotate, thereby stirring the raw materials;

[0029] A cleaning device 5 is provided on both sides of the connecting tube 3. Both ends of the cleaning device 5 are fixedly connected with support rods 501. A connecting ring 502 is fixedly connected between two adjacent support rods 501. The connecting ring 502 is rotatably and interlacedly connected with the main shaft 201 through a bearing. A one-way clamping device 6 is installed on the connecting ring 502. The one-way clamping device 6 is sleeved on the outside of the main shaft 201. The one-way clamping device 6 is used for unidirectional driving of the cleaning device 5. Through the setting of the one-way clamping device 6, when the main shaft 201 rotates counterclockwise, the one-way clamping device 6 can lock the connecting ring 502 and the main shaft 201, so that the main shaft 201 can synchronously drive the rotation of the connecting ring 502. When the main shaft 201 rotates clockwise, the relative state of the connecting ring 502 and the main shaft 201 is unlocked, so that the rotation of the main shaft 201 cannot drive the operation of the cleaning device 5.

[0030] Furthermore, the one-way clamping device 6 includes a clamping mechanism 61 and a one-way mechanism 62 . The clamping mechanism 61 is fixedly sleeved on the outside of the main shaft 201 , and the one-way mechanism 62 is arranged on the outside of the clamping mechanism 61 . The one-way mechanism 62 is installed on the connecting ring 502 .

[0031] Furthermore, the clamping mechanism 61 includes a rotating ring 611, a rotating claw 612 and an elastic rope 613. The rotating ring 611 is fixedly sleeved on the outside of the main shaft 201. The outer wall of the rotating ring 611 is provided with a plurality of slots in a circular array. The rotating claw 612 is rotatably arranged inside the slot. The elastic rope 613 is vertically fixedly installed inside the slot, and the elastic rope 613 and the rotating claw 612 fit each other. The clamping mechanism 61 also includes a positioning pin 614. The positioning pin 614 is rotatably inserted with the rotating claw 612. The positioning pin 614 is threadedly inserted and connected with the rotating ring 611. The positioning pin 614 facilitates the installation of a limited position of the rotating claw 612, so that the rotating claw 612 can only rotate around the axis of the positioning pin 614. The rotating ring 611 facilitates the installation of multiple rotating claws 612. The slot facilitates the storage of the rotating claw 612 when rotating clockwise, so that the clockwise rotation of the rotating claw 612 will not affect the movement of the one-way mechanism 62, and will not drive the rotation of the cleaning device 5. When there is no need to clean the inner wall of the stirring kettle body 1, the operation of the servo motor 2 only realizes the stirring function, thereby reducing the power consumption.

[0032] Furthermore, the one-way mechanism 62 includes a fixed wheel 621 and a one-way tooth 622. The fixed wheel 621 is fixedly mounted on the connecting ring 502. A plurality of one-way teeth 622 are fixedly mounted on the inner wall of the fixed wheel 621 in a ring array. The outer wall on one side of the one-way tooth 622 is inclined, and the outer wall on the other side of the one-way tooth 622 is vertically arranged relative to the inner wall of the fixed wheel 621. When the rotating claw 612 rotates toward the outer wall on the other side of the one-way tooth 622, the one-way mechanism 62 will be stuck, driving the one-way mechanism 62 to rotate synchronously.

[0033] Furthermore, the cleaning device 5 includes a connecting seat 51, a spring 52 and a scraper 53. The scraper 53 is slidably arranged on the inner side of the connecting seat 51. One end of the spring 52 is connected to the scraper 53, and the other end of the spring 52 is connected to the inner wall of the connecting seat 51. A guide rod is arranged inside the spring 52. One end of the guide rod is fixedly connected to the inner wall of the connecting seat 51, and the other end of the guide rod is slidably and interlacedly connected to the scraper 53. Through the guidance of the guide rod, the linear motion of the scraper 53 relative to the connecting seat 51 is more stable. Through the compression deformation of the spring 52, the elastic support of the scraper 53 is facilitated, so that the scraper 53 can be in close contact with the inner wall of the stirring tank body 1, and the cleaning is cleaner.

[0034] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
