[0029] The apparatus further includes an adjustable reciprocating transmission assembly 4 and a height adjustment assembly 5. The adjustable reciprocating transmission assembly 4 is mounted on the top of the mobile base 1 and is connected to the top output shaft of the dual-axis motor 21 and the outer wall of the paint tank 2.

Then, by starting the dual-axis motor 21, the stirring shaft 22 is driven to drive the agitator 23 to rotate, so that the agitator 23 can break up the paint loaded in the paint tank 2 to avoid condensation and poor caulking effect. Secondly, under the stirring action, the two sprockets 49 are connected by the chain 410, and the worm 47 and the worm wheel 46 are engaged, so that the turntable 45 rotates, cooperates with the setting of the transmission column 453 and the transmission groove 454, and then the reciprocating rod 43 drives the multiple nozzles 34 connected to the bottom end of the horizontal tube 33 to move back and forth, and then the paint is evenly sprayed in the opened gap, so that the filling effect is uniform, and the labor intensity of manual filling is greatly reduced, and the use effect is good. In addition, the screw a452 is rotated by the handle a, so that the distance between the transmission column 453 and the center of the turntable 45 can be adjusted, thereby making the reciprocating movement distance of the reciprocating rod 43 adjustable, which is convenient for filling gaps of different lengths and greatly improving its scope of application.
