[0026] The scraper mechanism 6 includes a stepper motor 61, a deflection wheel 62, a T-shaped plate 63, a transmission rod 64, a fixed ring 65 and a scraper 66. The stepper motor 61 is fixedly installed in the inner cavity of the horizontal plate 5, and the output end of the stepper motor 61 is fixedly connected to the deflection wheel 62. The top of the left side of the deflection wheel 62 is slidably connected to the T-shaped plate 63, and the center of the left side of the T-shaped plate 63 is fixedly connected to the transmission rod 64. The inner cavity of the horizontal plate 5 and the surface of the transmission rod 64 are fixedly connected to the fixed ring 65, and the left side of the transmission rod 64 passes through the left side of the horizontal plate 5 and is fixedly connected to the scraper 66.

[0027] refer to Figure 4 An annular groove 7 is provided on the left side of the deflection wheel 62 and corresponds to the position of the T-shaped plate 63 , and the annular groove 7 is used in conjunction with the T-shaped plate 63 .

[0028] As a technical optimization solution of the utility model, the annular groove 7 is provided to enable the T-shaped disk 63 to move inside the annular groove 7 and play a limiting role, thereby preventing the T-shaped disk 63 from being separated during operation.

[0029] refer to Figure 3 A return spring 8 is fixedly connected to the left side of the inner wall of the horizontal plate 5 and is sleeved on the surface of the transmission rod 64 , and the right side of the return spring 8 is fixedly connected to the left side of the fixing ring 65 .

[0030] As a technical optimization solution of the utility model, the reset spring 8 can assist the transmission rod 64 in working and play a role of reset buffer, thereby preventing the transmission rod 64 from being unable to reset after moving, causing the machine to be unable to continue working.

[0031] refer to Figure 2 A positioning sleeve 9 is fixedly connected to the bottom of the inner wall of the tank body 1 , and the top of the positioning sleeve 9 is movably connected to the bottom of the stirring rod 4 .

[0032] As a technical optimization solution of the utility model, the positioning sleeve 9 can assist the stirring rod 4 in working and play a fixing role at the same time, thereby avoiding the shaking phenomenon of the stirring rod 4 due to excessive load during work.

[0033] refer to Figure 2 The scraper 66 is made of stainless steel and is used in conjunction with the stirring rod 4 .

[0034] As a technical optimization solution of the utility model, the scraper 66 can assist the stirring rod 4 in working, and at the same time play a role of corrosion resistance, thereby avoiding the phenomenon of corrosion caused by the scraper 66 contacting the raw materials for a long time.

[0037] The working principle and use process of the utility model are as follows: when in use, raw materials are added into the tank body 1, and then the mixer 3 is started. The mixer 3 drives the stirring rod 4 and the horizontal plate 5 to rotate synchronously clockwise. The stepper motor 61 can be started at any time during the rotation of the horizontal plate 5 to participate in the stirring process. The stepper motor 61 drives the deflection wheel 62 to rotate clockwise. The deflection wheel 62 rotates to cooperate with the annular groove 7 so that the T-shaped plate 63 can move and move to the left according to the different angles of the contact with the deflection wheel 62. The T-shaped plate 63 moves to the left and drives the transmission rod 64 to move to the left. The movement of the transmission rod 64 stretches the reset spring 8 and works. Finally, the transmission rod 64 drives the scraper 66 to the left close to the inner wall of the tank body 1 for scraping.

[0038] In summary, the biotechnology fermentation device, through the coordinated use of the tank body 1, the cross beam 2, the stirrer 3, the stirring rod 4, the cross plate 5, the scraper mechanism 6, the stepper motor 61, the deflection wheel 62, the T-plate 63, the transmission rod 64, the fixing ring 65 and the scraper 66, solves the problem that the existing fermentation equipment needs to be stirred during the reaction process, but the raw materials adhering to the tank wall cannot be processed and cause waste.
