[0056] Specifically, the second driving member can comprise a rotary motor and a rotating member. The driving end of the rotary motor is connected to one end of the rotating member, and the other end of the rotating member is connected to the exhaust assembly 6. The rotary motor drives the rotating member to rotate, which in turn drives the exhaust assembly 6 to rotate.

[0057] Further, the extension direction of the rotating member is perpendicular to the digestion furnace 1. The exhaust assembly 6 can move along the extension direction of the rotating member to adjust the position of the exhaust assembly 6, so that the digestion tube joint 61 is sealed with the pipe opening of the digestion tube 3 or the joint of the digestion tube 3 is separated from the pipe opening of the digestion tube 3. In one embodiment, the rotating member is provided with a sliding rail arranged along the extension direction of the rotating member, and the exhaust assembly 6 is slidably connected to the rotating member. It should be noted that the exhaust assembly 6 can be locked when it is moved to the target position. In another embodiment, the rotating member is a telescopic member.

After digestion is completed, the third driving member 8 drives the second driving member 7 to move the exhaust assembly 6 upward, so that the digestion tube joint 61 is separated from the pipe opening of the digestion tube 3.

[0059] In another embodiment, the third driving end is connected with the exhaust assembly 6, and the third fixed end is connected with the second driving member 7. The third driving member 8 drives the exhaust assembly 6 to move, so as to drive the digestive tube joint 61 to move downward to seal with the pipe opening of the digestive tube 3, or to move upward to separate from the pipe opening of the digestive tube 3. In the case that the third fixed end is connected with the second driving end of the second driving member 7, the second driving member 7 can drive the third driving member 8 to rotate the exhaust assembly 6.

[0060] In order to realize automatic operation, the protein digestion device further comprises a controller, and the first driving member 4, the second driving member 7 and the third driving member 8 are all electrically connected with the controller.

[0061] In actual operation, the actions of the first driving member 4, the second driving member 7 and the third driving member 8 can all be controlled by the controller. Specifically, the controller controls the second driving member 7 to drive the exhaust assembly 6 to rotate and move away from the upper side of the digestion rack 2. A plurality of digestive tubes 3 are sequentially inserted into the digestion rack 2 by manual or machine. When the plurality of digestive tubes 3 are installed, the controller controls the second driving member 7 to drive the exhaust assembly 6 to rotate to the upper side of the digestive tube 3, wherein the digestive tube joint 61 on the exhaust tube corresponds to the digestive tube 3 on the digestion rack 2. Then, the controller controls the third driving member 8 to drive the exhaust assembly 6 to move downward until the digestive tube joint 61 seals with the pipe opening of the digestive tube 3. After the digestive tube joint 61 seals with the pipe opening of the digestive tube 3, the controller controls the first driving member 4 to drive the connecting member 5 to simultaneously move the third driving member 8, the second driving member 7, the digestion rack 2 and the exhaust assembly 6 downward until the digestive tube 3 is inserted into the digestion furnace 1. After heating is completed, the controller controls the first driving member 4 to drive the connecting member 5 to simultaneously move the third driving member 8, the second driving member 7, the digestion rack 2 and the exhaust assembly 6 upward. After the sample in the digestive tube 3 is digested, the controller controls the third driving member 8 to drive the exhaust assembly 6 to move upward to separate the digestive tube joint 61 from the pipe opening of the digestive tube 3. After separation is completed, the controller controls the second driving member 7 to drive the exhaust assembly 6 to rotate and move away from the upper side of the digestion rack 2, and the digestive tube 3 of the digestion rack 2 is taken away by manual or machine for next detection.

[0062] After the digestive tract joint 61 is sealed with the digestive tract 3, there is a minimum distance between the top surface of the digestion rack 2 and the bottom surface of the exhaust assembly 6, and the exhaust assembly 6 continues to move downward to damage the digestive tract 3 beyond the minimum distance. In order to prevent the exhaust assembly 6 from damaging the digestive tract 3 during movement, the utility model embodiment installs a distance sensor and an alarm, and the distance sensor is used to obtain the distance between the top surface of the digestion rack 2 and the bottom surface of the exhaust assembly 6. In order to facilitate the distance sensor to obtain the distance between the top surface of the digestion rack 2 and the bottom surface of the exhaust assembly 6, the distance sensor can be arranged on the top surface of the digestion rack 2. Further, the alarm and the distance sensor are electrically connected with the controller, and the controller is used to receive the distance information obtained by the distance sensor. In the case that the distance between the bottom surface of the exhaust assembly 6 and the top surface of the digestion rack 2 is less than the set threshold value, the controller sends a control signal to the alarm, and the alarm sends an alarm information such as alarm sound. At the same time, the controller sends a control signal to the third driving part 8, and the third driving part 8 stops running.
