[0021] As Figure 1 and Figure 2As shown in the figure, a plurality of first limiting rings 351 are provided on the support pipe 35, and a plurality of second limiting rings 352 are provided and arranged alternately with the first limiting rings 351. The sliding seat 36 is slidably connected within the range between the first limiting ring 351 and the second limiting ring 352. The first bracket 33 is close to the driver's seat direction of the mixer truck body. The driving mechanism 39 includes a compression spring 391 sleeved on the support pipe 35 and driving the sliding seat 36 to move towards the driver's seat direction of the mixer truck body, a plurality of connecting rods 392 hinged between adjacent sliding seats 36, an electric push rod 393 provided on the first bracket 33, and a cable 394 provided between the electric push rod 393 and the sliding seat 36 close to the second bracket 34.
[0022] As Figures 1 to 3 As shown in the figure, threaded holes 353 are provided on the side surfaces of the support pipe 35 close to the first limiting ring 351 and the second limiting ring 352. Fixed buckles 354 are threadedly connected to the threaded holes 353. The water supply hose 38 is embedded in a plurality of fixed buckles 354. The water supply hose 38 passes through the sliding seat 46 to avoid affecting the sliding of the sliding seat 46. A plurality of water supply branch pipes 381 connected to the spray heads 37 are connected to the water supply hose 38. The water supply branch pipes 381 do not affect the reciprocating movement of the sliding seat 36. And a metal universal joint 310 with a locking function is provided between the sliding seat 36 and the spray head 37. At the same time, the support pipe 35 is divided into multiple sections along the edge line of the top of the mixing drum 2, and a single first limiting ring 351 and second limiting ring 352 are installed on each section of the support pipe 35.
[0023] Implementation effect: During use, the water pump 32 transports the water in the water tank 31 to the water supply hose 38 and a plurality of spray heads 37, and the water is sprayed from the spray heads 37 onto the top of the mixing drum 2 for spray cooling; and in cooperation with the driving mechanism 39, the plurality of sliding seats 36 are reciprocally moved, so that the sprayed water is evenly sprayed onto the top of the mixing drum 2; at the same time, in cooperation with the rotation of the mixing drum 2 itself, uniform cooling is achieved, thereby prolonging the concrete setting time. When driving the plurality of sliding seats 36 to reciprocate, first, the plurality of sliding seats 36 are connected together by a plurality of connecting rods 392, and then, after the push rod of the electric push rod 393 extends and retracts and overcomes the elastic force of the plurality of compression springs 391, in cooperation with the cable 394, the plurality of sliding seats 36 are pulled to move towards the direction close to the second bracket 34.
