Description

Concrete mixer apparatus for repair

The present invention relates to a concrete mixer for repair, and more particularly, a mixing tank when mixing repair materials and water or repair liquid (coating agent, waterproofing agent, etc.) It relates to a concrete mixer for repairs that can control the amount of discharge by adjusting the inclination angle of the concrete mixer for repairs, which promotes convenience of work and maximizes constructability to facilitate repair work.

In general, repair materials are building materials that are applied to the floor or wall of a building, and these materials are mixed to form physical properties, and structural materials such as stone, wood, steel, and concrete are used to form each part of the building. Select and construct materials for repair suitable for partial performance and function, but after mixing the necessary materials in an appropriate ratio, the mixed repair agent is used.

These materials for repair are manufactured by applying various methods depending on the use, and in the construction field, products such as waterproofing agent, coating agent, and mortar made by mixing cement and the like are applied.

In particular, repair materials are required to have good mechanical properties and finish properties against wear, dents and scratches.

In addition, repair materials applied to various construction processes work by mixing various materials appropriately after construction. In general, due to the nature of repair materials, workers directly input materials at the site and use a repair system in which materials are mixed at a set ratio. used to cast quickly.

In this way, when constructing a repair agent (a state in which repair materials and water or repair liquid (coating agent, waterproofing agent, etc.) are mixed), it is usually used with a pouring machine and a separate mixer in which a mixer barrel is installed in a movable means provided in the form of a gourman. is done That is, various materials are weighed into the mixer barrel and put in an appropriate ratio, mixed for a certain time in the mixer barrel using a mixer, and then moved in a tilted state by rotating the worker around the shaft formed in the mixer barrel at the construction site. Mixed manufacturing and pouring methods are widely used.

Such a conventional manual mixer has an advantage in that it does not require a separate mixer equipment for mixing materials for repair, but there is a problem in that the quality is deteriorated after construction due to non-uniform mixing conditions.

In addition, like the conventional mixer device, the possibility that the worker directly comes into contact with the dust generated when the material made of powder is put in and causes a body respiratory disease is increased, and the lower part of the mixer barrel is tilted by the worker during the pouring operation. There was a problem in that the worker's fatigue was aggravated as the pouring operation was performed while maintaining the state.

It is characterized in that each of the opening and closing parts for opening and closing the drum cover by

In the prior literature configured as described above, since a drive motor for agitating the concrete contained in the drum is installed in the frame, the configuration for transmitting the rotational force to the blades transmitted through the chain is complicated, thereby increasing the manufacturing cost.

In addition, since the drum shaft is installed on the edge of the drum, one worker cannot rotate the drum due to the weight of the concrete during rotation of the drum, and at least two or more workers must rotate the drum before pouring. There is a problem that causes
