In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and should not be construed as indicating or implying relative importance.

The utility model is realized through the following technical solutions:

A hand-push concrete mixer, comprising a box mounting bracket 1, a mixing box 2 installed in the box mounting bracket 1, a push rod 3 connected to the box mounting bracket 1 and a mixing box 2 The fan drum 4 and the mixing drum 5 in the middle, the box body of the mixing box 2 is a drawer shape, the upper box surface of the mixing box 2 box body and one of the side surfaces are open surfaces, and the fan drum 4 is parallel to the mixing drum 5 The open surface on the side of the mixing box 2 is installed in the mixing box 2, and the blade drum 4 is installed close to the open surface of the side of the mixing box 2; the blade drum 4 and the mixing drum 5 are driven by a motor, and the push rod 3 is fixed with a handle 3.1 and power module 8. The blades of the blade drum 4 are strip blades parallel to the center of rotation of the blade drum 4 ; A fender 2.3 is arranged above the mixing box 2, and one end of the fender 2.3 is connected with the mixing box 2, and the other end is bent toward the open surface direction of the side of the mixing box 2. A number of rollers 2.1 are installed at the bottom of the mixing box 2 . Push rod 3 is far away from box body installation fixed frame 1 one end hinges and has push plate 3.2, and the opposite surface with push rod 3 connecting surface on push plate 3.2 is the circular arc shape of indentation. The push rod 3 and the box body are installed with a hinge of the fixed frame 1, and the upper hinge of the push rod has a limit rod 6. The upper and lower slots are aligned and distributed. The open surface of the stirring box 2 side is connected with a slant plate 2.2, and the slant plate 2.2 is connected with the stirring box 2 on one side, and the other side is inclined downward to contact the bottom surface.

The working mode of the present utility model is:

Firstly, before the mixing operation, the free end of the limit rod 6 is put into a suitable limit groove 7 to adjust the push plate 3.2 to the height required by the user. During the mixing operation, the mixture such as cement and sand is piled on the ground to form a sand pile. Then, the operator holds the handle 3.1, and the body leans against the push plate 3.2 to push the mixing box 2 towards the sand pile. In the process, the push plate 32 provides most of the thrust, and the handle 3.1 controls the direction.

In the process that the mixing box 2 is pushed in the sand pile, mixtures such as cement and sand are pushed into the mixing box 2, and the blade drum 4 initially mixes the mixture such as cement and sand, and then rolls it into the mixing box 2; The mixing drum 5 further stirs and mixes the mixture involved in the mixing box 2, and the curved barb-like blades on the mixing drum 5 can stir the mixture more finely to make it mix more evenly. The mixing drum 5 throws the mixture upwards during stirring, and the thrown mixture is blocked by the fender 2.3, and flies forward along the fender 2.3, falls on the forward direction of the device, and will be caught by the fan drum 4 again , was stirred again by circulation. The inclined plate 2.2 in front of the mixing box 2 can scoop up the cement and sand close to the bottom surface, and make them enter the mixing box 2 to be stirred, so as to prevent the height difference between the mixing box 2 and the bottom surface caused by the height difference between the mixing box 2 and the bottom surface due to the roller height 2.1. Cannot be stirred well.

When the silt within the width of one mixing box is evenly stirred, the mixing box 2 is pulled back through the handle 3.1, and the mixture in the mixing box 2 is poured out, and the above operation is repeated again. By repeatedly pushing and pulling back the device, small-scale concrete mixing operations can be realized, which saves time and effort compared to manual mixing with shovels.

After the device is used, just use a water gun or a water pipe to rinse the mixing box 2, and the sediment will flow out of the mixing box automatically with the flushing water.

It is worth mentioning that this device can be used not only for mixing concrete, but also for mixing various dry powder materials such as feed.
