Concrete mixing drum achieving easy drainage

Abstract

The invention discloses a concrete mixing drum achieving easy drainage. The concrete mixing drum achieving easy drainage comprises a drum body, wherein the bottom of the drum body is provided with a drainage port, a bottom plate used for plugging the drainage port and a flexible drainage channel, the bottom plate covers the outer side of the drainage port in a sealing mode, and one end of the bottom plate is hinged to the outer wall of the drum body. The flexible drainage channel comprises a water inlet. One part of the edge of the water inlet is connected to the free end of the bottom plate,the other part of the edge of the water inlet is fixed to the position, attached to the free end, of the outer wall of the barrel body, when the bottom plate is opened for water drainage, the free endof the bottom plate is turned outwards to open a water inlet, and the opened water inlet is connected to the drainage port in a sleeved mode. According to the concrete mixing drum achieving easy drainage, sewage and concrete can be discharged to the designated positions while cleaning is conducted, operation is easy, the cleaning speed is rapid, the cleaning degree is high, no residual sewage isaccumulated in the drum after cleaning, and the concrete mixing drum achieving easy drainage has great practical value.

Description

technical field [0001] The invention relates to the technical field of construction machinery, in particular to an easy-drainage concrete mixing drum. Background technique [0002] Concrete is a man-made material formed by uniformly mixing cement, water, sand, gravel and other main materials in an appropriate proportion, compacted and cured, and hardened. It is one of the most common materials in civil engineering and is widely used in housing. Buildings, bridges, roads and other areas. In daily concrete production, it is often necessary to use a concrete mixer to mix the materials that make up the concrete evenly. The concrete mixer is mainly composed of a mixing drum, a feeding and unloading mechanism, a water supply system, a prime mover, a transmission mechanism, a frame and a supporting device. Concrete mixing drum is a mixing container for concrete, usually in one-piece structure. For many large concrete mixers, the rotation space of the concrete mixing drum is inef...
