Description

Technical Field

[0001] The utility model relates to the technical field of recycled concrete processing, and particularly relates to a recycled concrete mixer. Background Art

[0002] Recycled concrete refers to new concrete prepared by crushing, cleaning and grading waste concrete blocks, mixing them in a certain proportion and gradation, partially or completely replacing natural aggregates such as sand and gravel (mainly coarse aggregates), and then adding cement, water, etc. There are the following situations for the combined form of recycled concrete aggregates: all aggregates are recycled aggregates; the coarse aggregates are recycled aggregates and the fine aggregates are natural sand; the coarse aggregates are natural crushed stones or pebbles and the fine aggregates are recycled aggregates; recycled aggregates replace part of the coarse aggregates or fine aggregates. A mixer is needed during the processing of recycled concrete. The dust generated during the use of the mixer is easy to fly around, which is likely to pollute the environment around the mixer. Therefore, a recycled concrete mixer is proposed to reduce the environmental pollution caused by dust. Content of the Utility Model

[0003] Aiming at the problems in the prior art, the utility model provides a recycled concrete mixer.

[0004] The technical solution adopted by the utility model to solve its technical problems is a recycled concrete mixer, which includes a tank body. A tank cover is provided at the top end of the tank body. A motor, a feed hopper and an air extraction pump are fixed at the top end of the tank cover. The output shaft of the motor is connected to a vertical rod through a coupling. A plurality of cross rods are fixed on the vertical rod. A bent pipe is fixed on the intake pipe of the air extraction pump. One end of the bent pipe far away from the air extraction pump is fixed with an annular first shell. A plurality of air inlet nozzles are fixed on the inner side of the first shell. All the plurality of air inlet nozzles extend into the feed hopper. An annular second shell is fixed on the outer side of the feed hopper. A plurality of atomizing nozzles are fixed on the inner side of the second shell. All the plurality of atomizing nozzles extend into the feed hopper. A connecting pipe is fixed on the exhaust pipe of the air extraction pump. The connecting pipe penetrates through the tank cover and extends into the tank body. A discharge valve and a plurality of legs are fixed at the bottom end of the tank body. A water bucket is provided on one side of the tank body. A water pump is fixed at the top end of the water bucket. A conduit is fixed on the intake pipe of the water pump. The conduit extends into the water bucket. A telescopic pipe is fixed on the discharge pipe of the water pump. One end of the telescopic pipe far away from the water pump is connected to the second shell.

[0005] By adopting the above technical solution, when the air extraction pump and the water pump operate and materials are added into the tank body through the feed hopper, the dust in the feed hopper and near the feed hopper enters the tank body through the connecting pipe. The water pump extracts the water in the water bucket, and the water is sprayed out through a plurality of atomizing nozzles, which can not only achieve dust reduction, but also prevent the dust in the tank body from escaping through the feed hopper, thereby reducing the environmental pollution caused by dust.

[0006] Specifically, blocks are fixed to both sides of the tank body, hydraulic cylinders are fixed to the tops of the two blocks, and the piston rods of the two hydraulic cylinders are connected to the tank cover.

[0007] By adopting the above technical solution, when the raw materials in the tank body are basically wetted and are not likely to generate dust during the stirring process, the piston rods of the two hydraulic cylinders drive the tank cover to move up and down, and the motor, the vertical rod and the cross rod move up and down accordingly, which is beneficial to the mixing of the raw materials in the tank body. After the recycled concrete in the tank body is discharged, the piston rods of the two hydraulic cylinders drive the tank cover to move up, which facilitates the opening of the tank cover and thus is beneficial to the maintenance of the interior of the tank body.

[0008] Specifically, an observation window is provided on the tank body, and a first piece of glass is provided in the observation window.

[0009] By adopting the above technical solution, it is convenient to observe the situation inside the tank body through the observation window and the glass.

[0010] Specifically, an observation opening is provided on the water bucket, a second piece of glass is provided in the observation opening, and scales are provided on the second piece of glass.

[0011] By adopting the above technical solution, it is convenient to observe the remaining amount of water in the water bucket through the observation opening and the second piece of glass.

[0012] Specifically, a water inlet is provided at the top of the water bucket, and a protective cover is provided in the water inlet.

[0013] The beneficial effects of the present utility model are as follows:

[0014] (1) For the recycled concrete mixer of the present utility model, when the air extraction pump and the water pump are operating and feeding materials into the tank body through the feed hopper, the dust in the feed hopper and near the feed hopper enters the tank body through the connecting pipe, and the water pump extracts the water in the water bucket, and the water is sprayed out through multiple atomizing nozzles, which can not only achieve dust reduction, but also prevent the dust in the tank body from escaping through the feed hopper, thereby reducing the environmental pollution caused by dust.

[0015] (2) For the recycled concrete mixer of the present utility model, when the raw materials in the tank body are wetted and do not generate dust during the stirring process, the piston rods of the two hydraulic cylinders drive the tank cover to move up and down, and the motor, the vertical rod and the cross rod move up and down accordingly, which is beneficial to the mixing of the raw materials in the tank body. After the recycled concrete in the tank body is discharged, the piston rods of the two hydraulic cylinders drive the tank cover to move up, which facilitates the opening of the tank cover and thus is beneficial to the maintenance of the interior of the tank body.
