[0015] Compared with the prior art, the utility model provides a concrete admixture metering start-stop anti-leakage device, which has the following beneficial effects:

[0016] 1. The concrete admixture metering start-stop anti-leakage device starts the first motor to rotate the screw through the lifting mechanism, and the rotation of the screw will cause the cross block to rotate. Since the cross block is limited by the limit plate, the limit groove, the sliding sleeve and the sliding rod, the rotation of the screw will cause the cross block to move downward, and the cross block will drive the fixed rod to move downward, thereby causing the disc and the sealing ring to move downward, and the disc is moved upward by the operation of the first motor. After moving to a certain position, the pipeline is connected to the feed pipe, and then the admixture is injected into the tank body. After the injection of the admixture is completed, the injection of the admixture is stopped through the control valve on the surface of the discharge pipe, and then the operation of the first motor causes the disc to move downward, thereby causing the sealing ring to move downward, and the disc and the sealing ring use pressure to discharge the admixture in the tank body from the tank body. When a certain amount of admixture is discharged, the operation of the first motor causes the disc and the sealing ring to move upward, thereby forming a pressure difference in the tank body, so that the admixture in the tank body will not be discharged from the tank body.

[0017] 2. The concrete admixture metering start-stop anti-leakage device starts the second motor through the rotating mechanism to rotate the worm. Since the worm is meshed with the worm wheel, the rotation of the worm will cause the worm wheel to rotate, and the worm wheel drives the rotating shaft to rotate. The rotation of the rotating shaft will cause the shielding disk in the discharge pipe to rotate. After the shielding disk rotates ninety degrees, the second motor stops working. At this time, the shielding disk will block the discharge pipe to prevent the residual admixture in the discharge pipe from flowing out. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] A hole matching the screw 414 is provided on the top of the fixing frame 411, and the diameter of the hole is larger than the diameter of the screw 414. The screw 414 passes through the hole. The diameter of the disc 417 is smaller than the diameter of the inner wall of the tank body 1. The diameter of the sealing ring 418 is larger than the diameter of the inner wall of the tank body 1. A control valve is provided on the surface of the feed pipe 419.

[0032] The limiting assembly 42 includes a limiting plate 421, which is fixedly connected to the left and right sides of the cross block 415.

[0035] Embodiment 2

[0036] See also Figure 4 , and on the basis of the first embodiment, a rotating mechanism 5 is further obtained.

[0037] The rotating mechanism 5 includes a connecting block 51, which is fixedly connected to the surface of the discharge pipe 3 in a left-right symmetrical manner. A sealed bearing 52 is fixedly connected to the side of the connecting block 51 away from the discharge pipe 3, a rotating shaft 53 is fixedly connected inside the sealed bearing 52, a baffle plate 54 is fixedly connected to the surface of the rotating shaft 53, a second fixed sleeve 55 is fixedly connected to the back side of the discharge pipe 3, a second motor 56 is fixedly connected inside the second fixed sleeve 55, a worm 57 is fixedly connected to the output of the second motor 56, and a worm wheel 58 is fixedly connected to the right end of the surface of the rotating shaft 53.

The diameter of the shielding plate 54 is equal to the diameter of the inner wall of the discharge pipe 3 , and the worm 57 is meshed with the worm wheel 58 .

[0039] In actual operation, when the device is used, the first motor 413 is started to rotate the screw 414, and the rotation of the screw 414 will cause the cross block 415 to rotate. Since the cross block 415 is limited by the limit plate 421, the limit groove 422, the sleeve 423 and the slide rod 424, the rotation of the screw 414 will cause the cross block 415 to move downward, and the cross block 415 will drive the fixing rod 416 to move downward, thereby causing the disc 417 and the sealing ring 418 to move downward.

After the injection of the additive is completed, the injection of the additive is stopped through the control valve on the surface of the discharge pipe 3. Then, the operation of the first motor 413 causes the disc 417 to move downward, thereby causing the sealing ring 418 to move downward. The disc 417 and the sealing ring 418 use pressure to discharge the additive in the tank body 1 from the tank body 1. When a certain amount of the additive is discharged, the operation of the first motor 413 causes the disc 417 and the sealing ring 418 to move upward, thereby forming a pressure difference in the tank body 1, so that the additive in the tank body 1 will not be discharged from the tank body 1;

[0040] Start the second motor 56 to rotate the worm 57. Since the worm 57 is meshed with the worm wheel 58, the rotation of the worm 57 will cause the worm wheel 58 to rotate. The worm wheel 58 drives the rotating shaft 53 to rotate. The rotation of the rotating shaft 53 will cause the shielding plate 54 in the discharge pipe 3 to rotate. After the shielding plate 54 rotates ninety degrees, the second motor 56 is stopped. At this time, the shielding plate 54 will block the discharge pipe 3 to prevent the residual additive in the discharge pipe 3 from flowing out.
