The specific contents are as follows:

[0020] 1. A metering assembly is provided inside and outside the metering hopper. When the raw material of the probiotic stock solution needs to be metered, the first electric valve is opened by the controller so that the raw material can fall into the metering hopper. After the raw material enters the metering hopper as a liquid, the buoyancy can drive the float ball to move upward, so that the U-shaped rod moves. After the U-shaped rod moves, the movable plate can be driven to slide on the vertical rod. The movable plate can gradually move upward as the amount of raw material in the metering hopper increases until the movable plate contacts the second detection switch. At this time, the controller controls the first electric valve to close, so that the second electric valve can be opened. The quantitative raw material in the metering hopper can be measured by the controller. The discharge pipe is used for discharge. With the discharge of the raw materials, the height of the float ball is continuously moved down until the movable plate contacts the first detection switch, and the raw materials inside the metering hopper are emptied. The second electric valve is closed by the controller, so that the first electric valve is opened, and the metering work can continue. The metering of the raw materials is realized by the movement of the float ball. Accurate metering can be achieved by using buoyancy, and it can be avoided that the float ball is difficult to reset during long-term use. The metering component ensures the accuracy of metering during the raw material metering process, and the accuracy of metering can still be guaranteed after long-term use, thereby improving the reliability and practicality of use.

[0021] 2. When metering, the capacity in the metering bucket is determined by the second detection switch. If you want to adjust the amount of raw materials, you can press the pressure rod to drive the movable block to move down, and then drive the mounting block to move through the cooperation of the sliding groove and the column rod, so that the positioning rod moves and stretches the telescopic spring, so that the positioning rod is disengaged from the positioning groove, and the position of the U-shaped frame is adjusted by the position of the pointer pointing to the scale line, and then the height of the second detection switch can be adjusted. After adjustment, release the pressure rod, and under the action of the telescopic spring, the positioning rod is reset and engaged with the other positioning groove to position the U-shaped frame, which makes it convenient for the staff to adjust the capacity of the raw materials inside the metering bucket according to needs, thereby improving practicality.

[0031] Working principle: Before using this raw material metering device for preparing probiotic stock solution, it is necessary to check the overall condition of the device to ensure that it can work normally. Figure 1 - Figure 5As shown, a metering assembly 2 is provided inside and outside the metering bucket 104. When the raw material of the probiotic stock solution needs to be metered, the first electric valve 105 is opened by the controller so that the raw material can fall into the metering bucket 104. After the raw material enters the metering bucket 104 as a liquid, the floating ball 203 can be driven upward by buoyancy to move the U-shaped rod 202. After the U-shaped rod 202 moves, the movable plate 205 can be driven to slide on the vertical rod 206. The movable plate 205 can gradually move upward as the amount of raw material in the metering bucket 104 increases until the movable plate 205 contacts the second detection switch 210. At this time, the controller controls the first electric valve 105 to be closed, which can open the second electric valve 107. The metering bucket 10 4 can be discharged through the discharge pipe 106. As the raw materials are discharged, the height of the float 203 is continuously moved down until the movable plate 205 contacts the first detection switch 207, and the raw materials inside the metering bucket 104 are emptied. The second electric valve 107 is closed by the controller, so that the first electric valve 105 is opened, and the metering work can continue. The metering of the raw materials is realized by the movement of the float 203. Accurate metering can be achieved by using buoyancy, and it can be avoided that the float 203 is difficult to reset during long-term use. The metering component 2 can ensure the accuracy of metering during the raw material metering process, and the accuracy of metering can still be guaranteed after long-term use, thereby improving the reliability and practicality of use.

[0032] When performing metering, the capacity in the metering bucket 104 is determined by the second detection switch 210. If the amount of raw material needs to be adjusted, the pressure rod 216 can be pressed to drive the movable block 217 to move downward, and then the mounting block 213 can be driven to move through the cooperation of the sliding groove 218 and the column rod 220, so that the positioning rod 211 moves and stretches the telescopic spring 212, so that the positioning rod 211 is disengaged from the positioning groove 214, and the position of the U-shaped frame 209 is adjusted by the position of the scale line pointed by the pointer 221, and then the height of the second detection switch 210 can be adjusted. After adjustment, the pressure rod 216 is released, and under the action of the telescopic spring 212, the positioning rod 211 is reset and engaged with the other positioning groove 214 to position the U-shaped frame 209, thereby facilitating the staff to adjust the capacity of the raw materials inside the metering bucket 104 according to needs, thereby improving practicality.
