Problems solved by technology

Since the dry material and water need to be mixed according to a certain ratio, it is necessary to put different amounts of water into the mixing drum according to a certain ratio before mixing different amounts of dry materials each time, because the current release of water is artificial. Control, the amount put into the mixing drum needs to be manually estimated, resulting in a certain deviation between the actual ratio of dry materials and water and the ideal ratio, which in turn affects the mixing quality of road and bridge construction materials
If the proportion of water is too much, it is not conducive to the rapid drying of construction materials; if the proportion of water is low, the dry material will still be dry after mixing, which will affect the normal use of road and bridge materials

Abstract

The present invention relates to the field of road and bridge material processing, in particular to a material mixing device for road and bridge, which includes a mixing drum, a stirring shaft and a driving mechanism for driving the stirring shaft to rotate, and also includes a base and a pumping tube, and the pumping tube is located on the base. The mixing drum is located above the pumping drum, and an elastic telescopic mechanism is connected between the mixing drum and the base; a piston is slid vertically in the pumping drum, a piston rod is connected between the piston and the mixing drum, and the water inlet pipe and outlet are connected to the pumping drum. A water pipe, the water inlet pipe is connected with a water source, the water inlet pipe is provided with a first one-way valve for allowing water to flow into the pumping cylinder in one direction from the water source, the water outlet end of the water outlet pipe is located above the mixing drum, and the water outlet pipe is provided with a A second one-way valve that allows water to flow out of the water cylinder in one direction. This scheme realizes that when more dry materials are added to the mixing drum, more water is added to the mixing drum, and when less dry materials are added to the mixing drum, less water is added to the mixing drum.

Description

technical field [0001] The invention relates to the field of road and bridge material processing, in particular to a material mixing device for road and bridge. Background technique [0002] During the construction of roads and bridges, mixing devices are required to mix concrete, gravel and other materials. The current mixing device includes a mixing drum, the inside of which is rotatably connected with a stirring shaft, the stirring shaft is provided with stirring blades, and the stirring drum is provided with a motor for driving the stirring shaft to rotate. When mixing, it is necessary to add dry materials such as concrete and gravel to the mixing drum, then add water to the mixing drum, start the motor, the motor drives the stirring shaft to rotate, and the stirring shaft stirs the dry materials such as concrete and water in the mixing drum. In order to make the materials in the mixing drum mix evenly. [0003] According to the needs of different areas of road and bri...
