In the construction process of roads and bridges, materials such as concrete, broken stones and the like need to be stirred by using a mixing device. At present, a mixing device comprises a mixing drum, a mixing shaft is rotatably connected inside the mixing drum, a mixing blade is arranged on the mixing shaft, and a motor for driving the mixing shaft to rotate is arranged on the mixing drum. During stirring, dry materials such as concrete and broken stones need to be added into the stirring cylinder, then water is added into the stirring cylinder, the motor is started, the stirring shaft is driven by the motor to rotate, and the stirring shaft is used for stirring the dry materials such as concrete and the like in the stirring cylinder and the water, so that the materials in the stirring cylinder are uniformly mixed.

According to different area requirements of road and bridge construction, the amount of materials stirred in the stirring cylinder is different every time, namely if the construction area is large, more materials are stirred in the stirring cylinder, and if the construction area is small, less materials are stirred and mixed in the stirring cylinder. The dry materials and the water need to be mixed according to a certain proportion, so that different amounts of water need to be added into a mixing drum according to a certain proportion before different amounts of dry materials are mixed, the release amount of the water is manually controlled at present, and the amount of the water added into the mixing drum needs to be manually estimated, so that the actual proportion of the dry materials and the water has a certain deviation from the ideal proportion, and the mixing quality of the road and bridge construction materials is influenced. If the proportion of water is too much, the construction material is not easy to dry quickly, and if the proportion of water is low, the dry material is still dry after being mixed, so that the normal use of the road and bridge material is influenced.

The invention aims to provide a material mixing device for a road and bridge, which is used for realizing that when a large amount of dry materials are added into a mixing drum, a large amount of water is added into the mixing drum, and when a small amount of dry materials are added into the mixing drum, a small amount of water is added into the mixing drum.

In order to achieve the purpose, the technical scheme of the invention is as follows: a material mixing device for a road and bridge comprises a mixing drum, a mixing shaft and a driving mechanism for driving the mixing shaft to rotate, wherein one end of the mixing shaft is positioned in the mixing drum, a discharging pipe is arranged on the mixing drum, the material mixing device also comprises a base and a water pumping drum, the water pumping drum is positioned on the base, the mixing drum is positioned above the water pumping drum, and an elastic telescopic mechanism is connected between the mixing drum and the base; the vertical sliding connection has the piston in the section of thick bamboo that draws water, is connected with the piston rod between piston and the churn, draws water to communicate on the section of thick bamboo to have inlet tube and outlet pipe, is connected with the water source on the inlet tube, is equipped with on the inlet tube to be arranged in making water follow the one-way first check valve that flows into in the section of thick bamboo that draws water of water source, and the play water end of outlet pipe is located the top of churn, is equipped with on the outlet pipe to be used for making water follow the.

The working principle and the effect of the scheme are as follows: the mixing drum is used for placing materials such as dry materials and water, the driving mechanism is used for driving the mixing shaft to rotate, and when the mixing shaft rotates, the mixing shaft is used for mixing and stirring the dry materials and the water in the mixing drum. The base is used for making this device put more steadily on ground. The water pumping cylinder is used for pumping water from a water source through the water inlet pipe and injecting the pumped water into the stirring cylinder through the water outlet pipe. When adding dry material in this scheme to the churn, the weight grow in the churn, and the churn extrudees elastic telescoping mechanism, and the churn moves down, and elastic telescoping mechanism holds power, and the churn promotes the piston downwards through the piston rod simultaneously to water in will drawing water the section of thick bamboo is gone into the outlet pipe, and water flows into in the churn through the outlet pipe. Therefore, in the scheme, if the dry materials are more put into the mixing drum, the weight of the mixing drum is larger, the downward moving distance of the mixing drum is larger, so that the downward moving distance of the piston is larger, and the amount of water in the water pumping drum drained into the mixing drum is correspondingly increased; if the dry materials put into the mixing drum are less, the weight of the mixing drum is smaller, the downward moving distance of the mixing drum is smaller, so that the downward moving distance of the piston is smaller, and the amount of water discharged into the mixing drum in the water pumping drum is smaller; therefore, the scheme can automatically realize the adjustment of the water adding amount into the mixing drum according to the amount of the dry materials added into the mixing drum (the dry materials are added more, the water amount is automatically added more, the dry materials are added less, and the water amount is automatically added less), and the water adding amount is not required to be manually controlled, so that the dry materials can be better mixed.

In addition, after the materials in the mixing drum are stirred, the materials in the mixing drum can be taken, along with the taking of the materials in the mixing drum, the weight of the mixing drum can be gradually reduced, the elastic force of the elastic telescopic mechanism can be larger than the weight of the mixing drum, so that the mixing drum moves upwards and gradually resets, the mixing drum upwards pulls the piston through the piston rod, the piston moves upwards, negative pressure is generated in the water pumping drum, the water at a water source is sucked through the water inlet pipe by the water pumping drum, and the automatic water supplement in the water pumping drum is realized. In the piston upward movement process, because the outlet pipe is provided with the second one-way valve, water in the outlet pipe can not flow downwards and is pumped into the water pumping cylinder, a certain amount of water can be reserved in the outlet pipe, and when the piston moves downwards next time, water in the outlet pipe can be discharged without waiting for the water in the water pumping cylinder to enter the outlet pipe and then flow out, so that the outlet pipe can discharge water timely.

Furthermore, the elastic telescopic mechanism comprises a telescopic rod and a pressure spring sleeved outside the telescopic rod, and two ends of the telescopic rod are respectively and fixedly connected to the bottom of the mixing drum and the base. From this, the telescopic link is used for carrying on spacingly to the pressure spring, takes place to buckle when avoiding the pressure spring to be compressed, and the pressure spring is used for providing pressure for can reset after the churn moves down.

Further, the telescopic link includes fixed pipe and slip tube, and the slip tube sliding connection is in fixed pipe. From this, through the relative slip of slip pipe in fixed pipe to the flexible of telescopic link has been realized.
