A mixing drum 2 for mixing concrete is installed on one side of the top of the carrying plate 1 through a support, and a discharge assembly 3 is located on the top of the carrying plate 1 and below the discharge port of the mixing drum 2;

[0028] The unloading assembly 3 includes a feeding cylinder 31 provided with a discharge port and a feed port. A rotating shaft 32 is installed at the bottom of the end of the feeding cylinder 31 close to the feed port, and the feeding cylinder 31 is rotatably installed on the top of the supporting plate 1 through the rotating shaft 32. A support frame 33 is welded to the end of the feeding cylinder 31 close to the discharge port, and the other end of the support frame 33 is slidably set on the top of the supporting plate 1. A driving motor 312 is installed at the end of the feeding cylinder 31 close to the discharge port, and a horizontal shaft 314 is installed at the driving end of the driving motor 312. The horizontal shaft 314 is located inside the feeding cylinder 31, and an auger blade 315 is welded on the outer wall of the horizontal shaft 314 located inside the feeding cylinder 31.

[0029] The process of discharging the material of the unloading component 3 is as follows:

[0030] The mixed concrete enters the interior of the feed barrel 31 through the guidance of the receiving cover 311, and the drive motor 312 drives the horizontal shaft 314 to rotate, thereby driving the auger blade 315 to rotate inside the feed barrel 31, pushing the concrete at the feed port toward the discharge barrel 313, and finally the concrete is discharged to the outside through the discharge barrel 313.

[0031] The equipment can be moved while pouring, which is conducive to pouring and inlaying at the same time, and is conducive to the rapid advancement of pouring narrow roads or pouring ditches. At the same time, when pouring concrete, the pouring mouth can rotate and swing to achieve horizontal unloading, expanding the pouring range without the need for manual dispersion of concrete, making the concrete dispersion more even and comprehensive, and improving work efficiency.

[0032] A crossbeam 21 is welded to the middle of the top of the mixing drum 2, and a stirring motor 22 is fixed to the top of the crossbeam 21. A stirring blade is installed at the driving end of the stirring motor 22, and the stirring blade is located inside the mixing drum 2.

[0036] When concrete is discharged from the discharge barrel 313, the servo motor 322 drives the rotating shaft 32 to rotate through the gear transmission part 321, and then drives the feed barrel 31 to rotate, so that the feed barrel 31 rotates with the rotating shaft 32 as the rotation point, and moves the position of the discharge port of the discharge barrel 313. That is, when the equipment is in a stationary state, the feed barrel 31 rotates with the rotating shaft 32 as the rotation point, so that the concrete is discharged horizontally, expanding the discharge range that the concrete can access.

[0037] During use, the discharge door 23 is closed to block the discharge port of the mixing drum 2, and the raw materials are poured into the mixing drum 2.
