[0021] Reference Figure 1-Figure 3 A hand-pushed asphalt mixer comprises a wheel frame 1 and a housing 3 mounted on the wheel frame 1, wherein a feed port is provided at one end of the housing 3, and asphalt raw materials can be put into the feed port;

[0022] A protective shell 7 is fixedly installed on the wheel frame 1 by bolts, and a battery 6 is fixedly installed under the protective shell 7 by bolts. An electric heating tube is also arranged in the housing 3, and the electric heating tube is electrically connected to the battery 6. The state of the electric heating tube can be controlled by the switch of the electric heating tube to prevent the asphalt from cooling and solidifying. This scheme does not involve improvements to the electric heating tube, so it is not described in detail.

[0023] The wheel frame 1 is fixed with an armrest frame 8 for pushing the housing 3, and the wheel frame 1 is fixed with a footrest frame 4 for tilting the housing 3. The maintenance worker grasps the armrest frame 8 with his hands, steps on the footrest frame 4 with his feet, pulls down with his hands, and pushes hard with his feet, so that the housing 3 can be pulled up, thereby facilitating the pushing;

[0024] The wheel frame 1 is also provided with a driving mechanism, which includes a motor 5, which is fixedly mounted on the wheel frame 1 by bolts, and the motor 5 is electrically connected to a battery 6, and the battery 6 can supply power to the motor 5.
