Description

Concrete mixer truck prevents throwing device

Technical Field

The application relates to the technical field of concrete production equipment, in particular to a concrete mixer truck anti-splashing device.

Background

Concrete production is the process of producing concrete by mixing various ingredients, water, aggregate, cement and additives. Concrete production is time-efficient. Once the ingredients are mixed, workers must pour the concrete before it hardens. In modern use, most of the concrete production is carried out in a large industrial facility called a concrete station or a concrete mixing station. The concrete mixed by mixing is transported to a construction site for use, and concrete mixing trucks of various countries are required to transport the concrete.

The invention discloses an anti-splashing device of a concrete mixer, which is disclosed in the Chinese patent with the application number of 201620961181.9, and comprises a leakage-proof hopper hinged at an outlet of an external discharge chute, and a limiting device used for preventing the leakage-proof hopper from shielding the outlet during discharging, wherein the limiting device is also used for aligning the leakage-proof hopper to the outlet during transportation. When the mixer truck is unloaded, the anti-leakage hopper is turned upwards to the position where the outlet of the discharge chute is not shielded, the position of the anti-leakage hopper is limited by the limiting device at the moment, and the shaking of the discharge chute enables the anti-leakage hopper to fall down to block the outlet when the mixer truck is unloaded. The export position is aimed at with the leak protection fill when the trucd mixer is normally transported, makes the concrete that spills can be lived by the leak protection fill pocket, and stop device will prevent that the position of funnel is injectd this moment, and the shake of automobile body makes the concrete in preventing the funnel shake off to ground when preventing the transportation, has avoided the pollution on ground.

With respect to the related art among the above, the inventors consider that the following drawbacks exist: the length of the discharging groove of the anti-splashing device is fixed, and after the stirring vehicle is parked at the designated position, the discharging groove is fixed and then the material is inconveniently thrown to different designated positions in the discharging process.
