At this time, the small end of the trapezoidal part 919 can be matched with the movable plate 921, so as to reset smoothly and complete the detection of the residual sand;

[0111] The residual sand in the sand collecting box 92 is discharged into the mixing box 10, and each time the collision head 918 collides with the No. 1 piston 917, the No. 1 piston 917 is driven to move along the inflating tube 915, so as to displace the air in the inflating tube 915. Squeeze into the exhaust runner 158 so that the No. 2 piston 156 follows the reserved cavity such as Figure 7 Move up in the direction shown, so as to store the air. When the detection of the residual sand content of the construction road is completed, the controller 8 can control the feeding box 7 to add the corresponding amount to the mixing box 10 according to the measured residual sand amount. The rest of the mortar raw materials in the volume are controlled by the staff to open the electric valve 157, and the gas passes through the exhaust flow channel 158 to collide with the conflicting blades, and drives the drive disc 152 and the turntable 154 to rotate together, so that under the action of the drive rod 97, the drive is driven. The shaft 12 reciprocates, and under the sliding cooperation between the spiral groove 14 and the ball 13, the stirring roller 11 is driven to rotate continuously to realize the preparation of mortar, and at the same time, the discharge nozzle 6 is controlled to open, and the entire device is moved to realize the laying of mortar. work to achieve the recycling of residual sand.
