A device that allows for the visual addition of a stable amount of admixture to a concrete mixer or similar equipment.

Abstract

When adding concrete admixtures to concrete mixer trucks or other vehicles after the fact, this system allows for highly accurate addition even at construction sites outside the factory, and enables visual confirmation of the flow. [Solution] By attaching a valve near the discharge port, leakage of the admixture from the tip is prevented. At the same time, by attaching a one-way valve in the middle of the hose, it becomes possible to fill the admixture up to the discharge port valve. By offsetting the transparent pipe by one degree relative to the object being injected, the flow of the admixture can be visually confirmed.

Description

Technical Field

[0001] When adding a concrete admixture or the like to a concrete mixer truck or the like, by filling the admixture up to the discharge port, the discharge of a flow monitor or the like that is inserted in between can be accurately input even at a site outside the factory, etc., and by making the discharge port pipe part transparent, the flow can be visually confirmed.

Background Art

[0002] Conventionally, due to a simple management method such as managing the input amount with a timer or the like, an error in the input amount has occurred.

[0003] Errors due to liquid level fluctuations in a tank or the like and leakage of the admixture from the discharge port. Since the discharge port faced the inside of the object to be input, it was difficult to confirm from the discharge port during input, and there was a drawback that the admixture leaked.

[0004] As an improvement measure, a valve is installed near the discharge port to prevent leakage of the admixture from the tip. At the same time, by installing a one-way valve in the middle of the hose, it becomes possible to fill the admixture up to the discharge port valve. By offsetting the pipe once with respect to the input object, the flow of the admixture can be visually confirmed.

Summary of the Invention

Problems to be Solved by the Invention

[0005] Errors in the discharge amount due to liquid level fluctuations in a tank or the like and leakage of the admixture from the discharge port. Since the discharge port faced the inside of the object to be input, it was difficult to confirm from the discharge port during input, and the admixture sometimes leaked. The present invention has been made to solve the above drawbacks.

Means for Solving the Problems

[0006] By installing a valve near the discharge port, leakage of the admixture from the tip is prevented. At the same time By installing a one-way valve in the middle of the hose, it becomes possible to fill the admixture all the way up to the discharge valve. By offsetting the transparent pipe by one degree relative to the material being injected, the flow of the admixture can be visually confirmed. [Effects of the Invention]

[0007] The flow monitor allows for stable control of the flow rate, enabling easy and highly accurate admixture input even at sites outside the factory. Furthermore, the ability to visually confirm the flow of the admixture ensures stable admixture input, which is a significant advantage.

Claims

[Claim 1] This device allows for the precise addition of admixtures to concrete mixer trucks and other vehicles by installing a valve near the discharge port and a one-way valve in the middle of the hose. This ensures that the admixture is filled right up to the discharge port, allowing for stable control of the flow rate on the flow monitor. The transparent discharge pipe allows for visual confirmation of the admixture flow, prevents leakage during transport, and enables highly accurate admixture addition.
