Description

Technical Field

[0001] The utility model relates to a concrete mixing device for road construction. Background Art

[0002] In the process of road construction, concrete is usually used as a structural material for construction. Concrete needs to be mixed during the production process. Concrete mixing is an operation method of mixing cement, lime, water and other materials and stirring them evenly.

[0003] The existing stirring device is operated by a stirring structure connected to a stirring tank and a motor output shaft. Since the concrete is viscous after stirring, and after the device has been working for a long time, a large amount of concrete residue is easily attached to the stirring structure on the motor output shaft and the inner wall of the stirring tank. The stirring structure in the existing device is located inside the stirring tank, which makes it inconvenient to clean the stirring structure and the inner wall of the stirring tank, which not only affects the cleanliness of the stirring structure, but also makes it difficult to ensure the efficient mixing of the subsequent concrete, and has certain limitations.

[0004] Therefore, it is necessary to provide a concrete mixing device for road construction to solve the above problems. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a concrete mixing device for road construction to solve the problems raised in the above background technology.

[0006] In order to solve the above problems, the utility model adopts the following technical solutions:

[0008] Preferably, the tops of both sides of the mixing tank are provided with extension parts, the tops of the two extension parts are provided with positioning grooves, and the bottoms of the top cover are provided with positioning blocks on both sides, and the positioning blocks are matched with the positioning grooves.

[0009] Preferably, connecting blocks are provided on both sides of the mixing tank, and the connecting blocks are fixed to the hydraulic cylinder.

[0010] Preferably, legs are provided on four sides of the bottom of the lower hopper.

The inner wall of the annular heating plate is in contact with the outer wall of the stirring tank, and the annular heating plate is connected to an external power supply device.

[0012] Preferably, a temperature sensor is provided on one side of the inner wall of the stirring tank, a controller is provided at the front end of the stirring tank, an input end of the controller is electrically connected to the temperature sensor, and an output end of the controller is electrically connected to the annular heating plate.

[0013] The beneficial effects of the utility model are as follows: concrete production raw materials are added to the mixing tank through the feeding pipe, the concrete raw materials are mixed and stirred through the driving motor, the stirring rod and the support rod, and the mixed concrete can be discharged through the control valve and the lower hopper. When the stirring rod and the support rod need to be cleaned, the stirring structure (the stirring rod and the support rod) is driven to move upward through the hydraulic cylinder and the top cover until it is separated from the inside of the mixing tank, so as to clean the concrete residues attached to the surface of the stirring rod and the support rod, and also to clean the concrete residues attached to the inner wall of the mixing tank. The utility model is arranged as above to clean the concrete residues attached to the stirring structure and the inner wall of the mixing tank, which not only ensures the cleanliness of the stirring structure, but also avoids the concrete residues occupying the internal space of the mixing tank and affecting the subsequent efficient mixing of concrete.
