A sampling device for ready-mixed concrete mixture

Abstract

The invention discloses a sampling device for a premixed concrete mixture. The sampling device structurally comprises a movable base, a jacking device, a travel switch, an unloading pipe, a solenoid valve, a hopper, a stirring controller, supporting plates, guide columns, four guide sleeves, a handle, a pushing handle, two wheel shafts, travelling wheels, a base plate and compression springs. Thetwo wheel shafts are arranged at the bottom of the movable base and are in parallel with each other. The two wheel shafts are mounted on the two sides of the bottom of the movable base correspondingly, and the two ends of the wheel shafts are connected with the traveling wheels. The top of the movable base is attached to the base plate through bolts, and the cylindrical compression springs are vertically placed on the base plate. The tops of the compression springs are connected with the top of the hopper, and the supporting plates are arranged on the two sides of the hopper. The four guide sleeves are distributed on the two sides of the hopper in pairs. According to the sampling device for the premixed concrete mixture, transmission can be conducted through the weight of concrete, the solenoid valve is closed to automatically stop unloading, the structure is reasonable, and the automation degree is high.

Description

technical field [0001] The invention relates to a sampling device for ready-mixed concrete mixture, which belongs to the field of sampling devices for ready-mixed concrete mixture. Background technique [0002] Ready-mixed concrete refers to cement, aggregates, water, admixtures, mineral admixtures and other components that are mixed according to needs in a certain proportion, and is sold at the mixing station after being measured and mixed, and is sold by transport vehicles. Concrete mix transported to the place of use within the specified time. Ready-mixed concrete has certain fluidity, cohesion and plasticity, also known as fresh concrete. [0003] The sampling hopper of the sampling device in the prior art senses the weight of the concrete in the hopper through the gravity sensor, so as to calculate the volume of the concrete. When it reaches a certain level, it will automatically alarm to remind the staff to listen to unload the material. When sampling, the hopper cann...
