The feed shaft 16 is connected to the output shaft of the material screed motor 19, which is fixedly connected to the hopper 11. When the material screed motor 19 is operating, it drives the material to the left and right sides via the first and second rotary auger blades 15, 17.

[0024] A handle 24 is provided at the rear of the hopper 11 . The handle 24 is rotatably connected to a handle seat 23 , and the handle seat 23 is fixedly connected to the hopper 11 .

[0025] A top beam 2 is provided at the front of the frame 1, and a flat plate 4 is provided below the top beam 2. The flat plate 4 is connected to the top beam 2 through a linear reciprocating mechanism. The lower surface of the flat plate 4 is horizontal, the length direction of the flat plate 4 is left and right, and the linear movement direction of the linear reciprocating mechanism is left and right. In this embodiment, the linear reciprocating mechanism is specifically: it includes a smoothing motor 26, a crank 9, a connecting rod 8, a slider 5, a guide rod 7 and a hanging column 3; the number of the hanging columns 3 is 2, the top of the hanging column 3 is fixedly connected to the top beam 2, and the two ends of the guide rod 7 are respectively fixedly connected to the two hanging columns 3; the number of the sliders 5 is 2, and the two sliders 5 are arranged along the length direction of the flat plate 4, the slider 5 is fixedly connected to the connecting plate 6, the connecting plate 6 is fixedly connected to the flat plate 4, and the slider 5 is slidably connected to the guide rod 7; one end of the connecting rod 8 is hinged to one of the sliders 5, the other end of the connecting rod 8 is hinged to the first end of the crank 9, the second end of the crank 9 is fixedly connected to the output shaft of the smoothing motor 26, the smoothing motor 26 is fixedly connected to the motor mounting plate 25, and the motor mounting plate 25 is welded to the bottom of the top beam 2.

[0026] The machine also includes a flat plate height adjustment unit. Specifically, the unit comprises: side plates 10 are fixed to each end of the top beam 2. Each side plate 10 is provided with at least two oblong holes 12. Screws 14 pass through flat washers 13 and the oblong holes 12 in the side plates 10, and are screwed into corresponding threaded holes in the frame 1, thereby securing the side plates 10 to the frame 1. Nuts 32 are fixedly connected to the top beam 2, which in turn are screwed into screw rods 30. Screw rods 30 are rotationally connected to bearing seat 29 via rolling bearings C34.

The controller can be fixed on the frame 1 or a handheld remote control. The choice of the controller form is common sense for those skilled in the art, so it will not be repeated here.

[0029] The principle of use of this embodiment: When in use, pour the concrete material into the middle part of the hopper 11, and the first rotary auger blade 15 and the second rotary auger blade 17 are driven to rotate by the material leveling motor 19, thereby driving the material to move to the left and right sides, so that the material is discharged evenly from the discharge port at the bottom of the hopper 11. When the height of the plate 4 needs to be adjusted, first loosen the screw 14. At this time, the oblong hole 12 and the screw 14 will become the guide for the side plate 10 to move up and down; rotate the manual turntable 28 to drive the screw 30 to rotate, thereby moving the top beam 2 up and down, and then driving the plate 4 up and down to adjust the height of the plate 4. After the height of the plate 4 is adjusted appropriately, tighten the screw 14. In the process of paving concrete, the action of the smoothing motor 26 is controlled to move the plate 4 left and right to smooth and compact the paved material.
