The discharge hole 116 is slidably connected to the top of the outer surface of the discharge device 115. Whenever the discharge device 115 rotates one circle, the quicklime inside the lime tank 102 enters the interior of the discharge device 115 through the discharge hole 116, and enters the interior of the self-leveling cement through the discharge device 115. Intermittent discharge prevents the discharge hole 116 from discharging too much material or being blocked.

[0033] like Figure 1-5As shown, a belt 2 113 is fixedly sleeved on the outer surface of the long rod 109 near its bottom, and a short rod 114 is movably sleeved on one end of the belt 2 113. The short rod 114 is fixedly connected to the bottom of the outer surface at the center of the discharging device 115.

The brush 119 inserted into the interior of the self-leveling cement will stick to the cement, and the cement can be cleaned off by the rotation of the brush 119 to avoid difficult cleaning due to a long time, thus saving manpower.

[0035] like Figure 1-5 As shown, the bottom of the outer surface of the support plate 107 is connected to an electric push rod 121 through a bearing, the bottom end of the electric push rod 121 is fixedly connected to a detection rod 120, a plurality of brushes 119 rotate on the outer surface of the detection rod 120, and the hollow gear 117 is connected to the bearing through a plurality of rods at the top, and the bearing is connected to the bottom of the outer surface of the support plate 107, and when the long rod 109 rotates, the linkage gear 118 is driven to rotate.

[0036] like Figure 1-5 As shown, a linkage gear 118 is fixedly connected to the bottom end of the long rod 109 , and the linkage gear 118 is meshedly connected to the outer surface of the hollow gear 117 , and the linkage gear 118 drives the brush 119 on the meshed hollow gear 117 to rotate on the outer surface of the detection rod 120 .

[0037] Working principle: When in use, the electric push rod 121 is started by an external power supply to push the detection rod 120 downward. After the movement, the detection rod 120 detects the pH value of the self-leveling cement. When the electric push rod 121 drives the detection rod 120 to move upward, the motor 108 is started by the power supply to drive the long rod 109 to rotate. It should be noted that the hollow gear 117 is connected to the bearing through multiple rods on the top, and the bearing is connected to the bottom of the outer surface of the support plate 107. When the long rod 109 rotates, it drives the linkage gear 118 to rotate. The linkage gear 118 drives the brush 119 on the meshing hollow gear 117 to rotate on the outer surface of the detection rod 120. The brush 119 is inserted into the inside of the self-leveling cement and will stick to the cement. The cement is cleaned off by the rotation of the brush 119 to avoid cleaning being difficult due to long time, saving manpower. When the detection rod 120 detects a low pH value in the self-leveling cement, quicklime is poured onto the top of the outer surface of the screen 103. When the motor 108 drives the long rod 109 to rotate, the belt 110 drives the reciprocating screw 111 to rotate at the same time. The top rod 112 slides up and down on the outer surface of the reciprocating screw 111. The limit rod 1121 limits the top rod 112. The top rod 112 reciprocates and hits the outer surface of the screen 103. Under the limit of the spring 106, the screen 103 slides inside the chute 105, and the screen 103 vibrates, so that the impurities and lumps inside the quicklime on the upper surface of the screen 103 are screened out. In order to improve the construction quality of self-leveling cement, the long rod 109 drives the discharging device 115 to rotate at the bottom of the lime tank 102 through the belt 113 when it rotates. The discharging device 115 is movably embedded in the bottom of the lime tank 102. Whenever the discharging device 115 rotates one circle, the quicklime inside the lime tank 102 enters the inside of the discharging device 115 through the discharging hole 116, and enters the inside of the self-leveling cement through the discharging device 115. When the pH value of the self-leveling cement is relatively low, the pH value is increased, and the rotation of the discharging device 115 can realize intermittent discharging, thereby preventing the discharging hole 116 from being blocked during discharging.
