The lower part of the material box 2 is provided with a material leakage pipe extending into the corresponding side chamber 20, and the material dish 4 is correspondingly below the material leakage pipe. As shown in FIG. 5 , six (three on each side in the figure) pans 4 are distributed on the bottom wall of the side chamber 20 . In some embodiments, corresponding to each pan 4 in the A material leakage pipe is arranged at the bottom of the material box 2 . In some other embodiments, only one material leakage pipe may be provided at the lower part of each material box 2 . At this time, the drive can be set so that the material box 2 can move back and forth in a straight line along the front and rear direction, so that the material leakage pipe can correspond to the top of each material dish 4 .

In one embodiment, as shown in FIG. 1 , FIG. 3 , and FIG. 4 , the driving mechanism includes a roller 18 and a motor 19 , and a pull rope 181 is wound on the roller 18 . The side plate of the side chamber 20 is provided with a long slot for the sealing plate to penetrate into the side chamber 20 . The roller 18 and the motor 19 are relatively arranged below the slotted hole. The sealing plate is a hinged sealing plate 17 pivotally installed at the long slot hole on the side plate 14 . A section of the hinged sealing plate 17 extending into the side chamber 20 is matched with the leakage pipe, and a section extending to the outside is connected to the free end of the stay rope 181 wound on the roller 18, and the The length of the hinged sealing plate 17 extending into the side chamber 20 is much greater than the length extending to the outside. For example, with the pivot as the boundary, the length of the former is 3 times, 5 times, 6 times, 7 times, 8 times, etc. (not necessarily an integer multiple) of the length of the latter. The bottom of the side plate 14 is provided with a cavity 143, a support is installed in the cavity 143, and the roller 18 and the motor 19 are fixed on the support.

As shown in Fig. 1, Fig. 3 and Fig. 4, the set hinged sealing plate 17 realizes the function of sealing the lower port of the leaking pipe and forming a gap with the lower port of the leaking pipe by rotating around the pivot. In order to ensure that the hinged sealing plate 17 can form a gap between its upper end surface and the lower port of the leakage pipe when it rotates downward, as shown in Figure 3, at least the outer port of the long slot on the side plate 14 The upper part is provided with a notch 141, and the lower part of the inner port is provided with a notch 2 142, and the notch 1 141 and the notch 2 142 can make way for the hinge sealing plate 17 to tilt downward relative to the horizontal plane. In the structure shown in FIG. 3 , when the hinged sealing plate rotates to the horizontal plane, it can seal the lower port of the leakage pipe.

The control unit can control the motor 19 to drive the roller 18 to rotate forward and reverse, so that the pull cord 181 is tightly wound on the roller 18 and disengaged from the roller 18 . When the stay cord 181 is wound on the roller 18, the stay cord is gradually straightened to drive the hinged sealing plate 17 to rotate upwards to block the lower port of the leakage pipe. When the stay cord 181 disengages from the roller 18, as the length of the stay cord increases, under the action of the center of gravity of the hinged sealing plate, it gradually rotates downwards to form a gap with the lower port of the leakage tube.

The driving mechanism shown in Figure 1, Figure 3, and Figure 4 has a simple, compact structure, reliable operation, and does not occupy much internal space in the side chamber, which helps to reduce the volume of the overall design structure of the scheme.

As shown in 1 and the design scheme shown in Figure 3, the lower port of the leakage pipe at the bottom of the material box 2 is a plane port parallel to the horizontal plane, and the hinged sealing plate 17 extends to a section in the side chamber 20 that is in the When in the horizontal plane, it can contact the plane port of the leakage pipe to block the lower port of the leakage pipe. In some embodiments, the lower port of the leakage pipe can also be a wedge surface inclined upwards or downwards. At this time, the hinged sealing plate 17 needs to continue to rotate after being rotated to the horizontal plane to seal the opening of the leakage pipe.

The S baffle plate 22 is a thin metal plate, which can be deformed to a certain extent after bearing the weight of the food material.

By arranging the S baffle 22, the food material can only be dropped by the gap between the S baffle 22 and the inner wall of the leaking pipe after the near hinge end of the hinged sealing plate 17, and then slide down to the food material by the hinged sealing plate 17. Dish 4. The effect that arranges like this, can improve the impact force situation that hinged sealing plate 17 bears in the process of blocking the lower port of the leaking material pipe, avoid clamping the food material between the hinged sealing plate 17 and the lower end surface of the material leaking pipe ( During the upward rotation of the hinged sealing plate, food materials that cannot slide down from the hinged sealing plate are collected under the S baffle plate 22), which can enhance the blocking effect.

In some embodiments, in addition to the hinged form shown in Figure 3, the sealing plate used to seal the lower port of the leakage pipe can also adopt the form of moving up and down. That is, under the drive of the driving mechanism, the sealing plate moves to make its upper end contact with the lower port of the leakage pipe to realize sealing; driven by the driving mechanism, the sealing plate moves down so that its upper end contacts the leakage pipe. The lower port of the tube is gradually disengaged, creating a large enough leakage gap.
