[0034] One specific application of the embodiment is:
[0035] After concrete is added, motor 24 is started. The output of motor 24 drives the drive shaft 241 to rotate, which in turn drives gear 242 to rotate. Gear 242 then drives driven shaft 232 to rotate, which in turn drives mixing arms 184 of varying lengths to rotate. Mixing arms 184 drive mixing base plate 185 and scraper 181 to rotate. The mixing mechanism 18 continuously mixes the concrete, ensuring that all the concrete ingredients are combined. Using mixing arms 184 of varying lengths allows for faster mixing of the ingredients. This method is more energy-efficient. Simultaneously, the pump casing 22 is activated, and the inlet 151 is connected to a water source. The pump casing 22 allows water to be sprayed from the spray nozzle 152 through the water pipe 153. A certain proportion of water is added according to the weight of the concrete, eliminating the need for manual water addition to the mixer, thus saving labor. During mixer operation, the pump casing 22 can be activated, and using the same principle, the oil spray nozzle 163 sprays lubricating oil onto the connection between the driven shaft 232 and the top of the fixed block 183, making the driven shaft 232 rotate more smoothly. This makes the mixing mechanism 18 more efficient, and consequently, the equipment is more energy-efficient. To enhance energy efficiency, after concrete mixing is complete, valve 11 is opened. The drum base 171, being a sloped base, causes the mixing base plate 185 to continuously drive concrete out of the discharge port 711. When concrete stops flowing out of the discharge port 711, the pump casing 22 is opened, and the water inlet 151 is connected to a water source. Water is sprayed into the mixing drum 17 through the water pipe 153 and the spray nozzle 152 to wash away residual concrete on the mixing mechanism 18. The fixing plate 141 and brush 144 are then flipped to the top of the mixing drum 17, with the bottom of the fixing plate 141 contacting the rotating shaft 233. When the driven shaft 232 rotates, it drives the collision block 145 to rotate. The collision block 145 collides with the collision head 411 at the bottom of the fixed plate 141. When the hemispherical collision head 411 collides with the collision block 145, it will move upward and then fall due to gravity, thereby driving the brush 144 to vibrate up and down, thereby cleaning the concrete on the mixing arm 184, mixing base plate 185, mixing arm 2 186 and mixing arm 3 187, avoiding the situation where concrete residue will clump and affect subsequent use, making the equipment more efficient when mixing concrete again, thus making the equipment more energy-efficient.
