DETAILED DESCRIPTION

[0021] In order to make the above-mentioned purpose, features and advantages of the utility model more clearly understood, the utility model is further described below in combination with the drawings and embodiments. It should be noted that the embodiments of the application and the features in the embodiments can be combined with each other without conflict.

[0022] ​​Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] like Figures 1-4 As shown, a discharge overflow airlock device for a grinding equipment includes a movable adjusting plate 1 and a fixed adjusting plate 2 disposed within a known housing. The housing referred to here is the housing described in the background art as "the housing of the discharge overflow airlock device for grinding equipment, publication number: CN221521296U". A locking block 8 is fixedly installed on one side of the upper surface of the fixed adjusting plate 2. The lower surface of the movable adjusting plate 1 is embedded in and locked onto the locking block 8, sliding along the length of the fixed adjusting plate 2. A lead screw 7, threadedly connected to the locking block 8, is rotatably connected to the lower surface of the movable adjusting plate 1. A motor 6 for driving the lead screw 7 to rotate is installed on one side of the movable adjusting plate 1. In practical use, one possible solution is that the fixed adjusting plate 2 is fixed within the housing, and the movable adjusting plate 1 is slidably installed within the housing. Therefore, the motor 6 drives the lead screw 7 to rotate, utilizing the threaded connection between the lead screw 7 and the locking block 8. 8. When the fixed adjusting plate 2 is fixed and cannot move, the screw 7 can move relative to the locking block 8 during rotation, thus enabling the moving adjusting plate 1 to move relative to the fixed adjusting plate 2 for automatic position adjustment, thereby adjusting the level of the flowing material in the box. Both the moving adjusting plate 1 and the fixed adjusting plate 2 have embedded gap sealing strips 5 along their two long sides. Connecting plates 14 are fixedly installed on opposite sides of the two gap sealing strips 5 in both the moving adjusting plate 1 and the fixed adjusting plate 2, and a first spring rod 15 is installed between them. Electric push rods 9 are fixedly installed between the two connecting plates 14 in both the moving adjusting plate 1 and the fixed adjusting plate 2. The electric push rods 9 extend and retract along the length of the gap sealing strips 5, and their extension ends are fixedly connected to push plates 10 for moving the two connecting plates 14 located in the same plate. Figure 4 The structure inside the movable adjustment plate 1 differs from that inside the fixed adjustment plate 2 in that it lacks the piston plate 13, piston shell 11, air filling channel 17, and second spring rod 16. Therefore, after the position of the movable adjustment plate 1 is adjusted, the push plate 10 can be moved by extending the electric push rod 9 inside the movable adjustment plate 1. The two connecting plates 14 are moved by the contact between the inclined edge of the head of the push plate 10 and the inclined edge of the connecting plate 14, thus overcoming the pulling force of the first spring rod 15. This allows the gap sealing strip 5 to extend out of the movable adjustment plate 1 and fit tightly against the inner wall of the box, achieving a seal and preventing material from leaking out from the gap.

[0024] Further, the head of the push plate 10 is trapezoidal, the opposite side of the two connecting plates 14 in the same plate and close to the side of the electric push rod 9 is provided with an inclined edge for sliding connection with the head of the push plate 10, when the straight edge of the push plate 10 contacts and slides with the straight edge of the connecting plate 14, the push plate 10 continuously moves to the right and the connecting plate 14 does not move.

[0025] Further, the side of the fixed adjusting plate 2 away from the clamping block 8 is provided with a rotating shaft 3 for penetrating and rotating connection with the inner wall of the box, in actual use, the fixed adjusting plate 2 can be connected with the inner wall of the box in a penetrating and rotating manner, at this time, the two gap sealing strips 5 arranged in the fixed adjusting plate 2 can realize the sealing of the gap between the fixed adjusting plate 2 and the box by referring to the movement mode of the gap sealing strips 5 in the movable adjusting plate 1, the auxiliary sealing strip 4 is inlaid and connected at the top edge of the side of the fixed adjusting plate 2 close to the rotating shaft 3, the auxiliary sealing strip 4 is movably connected with the inner wall of the fixed adjusting plate 2 through the first spring rod 15, and the side edge of the auxiliary sealing strip 4 is fixedly connected with the second spring rod 16 penetrating the surface of the fixed adjusting plate 2, the second spring rod 16 is vertically distributed with the first spring rod 15 on the gap sealing strip 5, and the extension end of the second spring rod 16 is used for abutting against the head of the push plate 10, in combination with Figure 4 and Figure 2 When the straight edge of the side of the push plate 10 contacts the straight edge of the side of the connecting plate 14, the push plate 10 continuously moves and the connecting plate 14 does not move, so when the push plate 10 moves to contact the extension end of the second spring rod 16 and pushes the second spring rod 16 to move, the second spring rod 16 drives the auxiliary sealing strip 4 to move out of the fixed adjusting plate 2, thereby realizing the sealing between the swing edge of the fixed adjusting plate 2 and the inner wall of the box.

[0026] Further, the side of the fixed adjusting plate 2 close to the clamping block 8 is provided with the air bag 12, the air bag 12 is U-shaped and is used for sealing the gap between the fixed adjusting plate 2 and the bottom surface of the movable adjusting plate 1, the piston shell 11 is arranged in the fixed adjusting plate 2 close to the electric push rod 9, the piston plate 13 connected with the extension end of the electric push rod 9 in the fixed adjusting plate 2 is movably arranged in the piston shell 11, the inflation channel 17 for connecting the air bag 12 and the piston shell 11 is arranged in the fixed adjusting plate 2, when the electric push rod 9 in the fixed adjusting plate 2 moves to the right, the piston plate 13 in the piston shell 11 moves to the right, thereby realizing that the air in the piston shell 11 enters the air bag 12 along the inflation channel 17, and realizing that the air bag 12 inflates, by inflating to contact the bottom surface of the movable adjusting plate 1 and the inner wall of the box, the sealing of the overlapping part of the fixed adjusting plate 2 and the movable adjusting plate 1 can be realized.

[0027] The working principle is that, referring to the known technology, the fixed adjusting plate 2 is fixed in the box, the movable adjusting plate 1 is slidingly installed on the surface of the fixed adjusting plate 2, the motor 6 is used to drive the screw rod 7 to rotate, the screw rod 7 is threadedly connected with the clamping block 8, and the clamping block 8 is fixed with the fixed adjusting plate 2 and cannot move, so that the screw rod 7 can move relative to the clamping block 8 in the rotating process, the movable adjusting plate 1 can move relative to the fixed adjusting plate 2 to realize automatic position adjustment, and the material level in the box can be adjusted.

[0028] The wiring diagram of the motor 6 and the electric push rod 9 in the utility model belongs to the common knowledge in the field, the working principle is the known technology, the model is selected according to the actual use, so the control mode and the wiring arrangement of the motor 6 and the electric push rod 9 are not explained in detail.
