The timing piece and the control piece are installed on the driving assembly 20 to control the driving assembly 20 to work to drive the pump body assembly 30 to intermittently transport slurry.

[0026] Referring to Figure 1 and Figure 2 , the driving assembly 20 comprises a motor 21 and a shaft coupling 22, the pump body assembly 30 comprises a conveying pump 31 and a feeding port 32 and a discharging port 33 arranged on the conveying pump 31, the output shaft of the motor 21 is fixedly installed on one side of the shaft coupling 22, and one side of the shaft coupling 22 is fixedly connected with the conveying pump 31. The feeding port 32 is communicated with one side of the conveying pump 31, the discharging port 33 is communicated with the end of the conveying pump 31 away from the motor 21, and the slurry enters from the feeding port 32 and is controlled to work under the driving of the motor 21 to be output from the discharging port 33.

[0027] Further, referring to Figure 3The conveying pump 31 comprises a pump shell 311 arranged in the conveying pump 31, a conveying cavity 312 for conveying the slurry in the pump shell 311, a driving screw 313 arranged in the conveying cavity 312, and a driven screw 314 threadedly engaged with the driving screw 313. The driving screw 313 is rotatably connected to the inside of the conveying pump 31 through a bearing, one end of the driving screw 313 penetrates through the conveying pump 31 and is connected with one side of the shaft coupling 22 to be connected with the motor 21. The motor 21 drives the driving screw 313 to rotate, and the driving screw 313 drives the driven screw 314 to rotate, so as to transport the slurry in the conveying cavity 312 from the feeding port 32 to the discharging port 33 of the conveying pump 31.

[0028] Further, referring to Figure 1 and Figure 2 , the feeding port 32 and the discharging port 33 of the conveying pump 31 are both provided with flanges 40. The flanges 40 are used for conveniently connecting the pipes to the feeding port 32 and the discharging port 33.

[0029] Further, referring to Figure 1 and Figure 2 , the conveying pump 31 and the base 10 are provided with fixing frames 50 for supporting the conveying pump 31 on the base 10. The fixing frames 50 are arranged in an L shape, the upper side of the fixing frame 50 is fixedly connected with the outside of the conveying pump 31, and the lower side of the fixing frame 50 is fixedly connected with the base 10 through foundation bolts. In the embodiment, there are two fixing frames 50, which are arranged at a distance and are both located at the position of the conveying pump 31 close to the discharging port 33. The conveying pump 31 is supported by the fixing frames 50, so that the conveying pump 31 is more stable when conveying the slurry, and the conveying pump 31 is prevented from shaking.

[0030] Further, referring to Figure 1 and Figure 2 , the connection between the motor 21 and the conveying pump 31 is provided with a bracket 60, which is fixed on the base 10. In the embodiment, the bracket 60 is fixed on the base 10 through foundation bolts. One end of the driving screw 313 of the conveying pump 31 close to the motor 21 penetrates into the bracket 60, and the output shaft of the motor 21 also penetrates into the bracket 60. The driving screw 313 and the output shaft of the motor 21 in the bracket 60 are connected through the shaft coupling 22.

When the motor 21 controls the conveying pump 31 to convey slurry to the timing time, the timer 70 gives an alarm, so that the controller 80 controls the motor 21 to stop working, until the timer 70 gives an alarm again to prompt that the conveying slurry is needed, the controller 80 controls the motor 21 to work, so as to make the conveying pump 31 convey slurry to the coating slurry buffer tank. It should be noted that the filter device is installed on the outlet pipe of the conveying pump 31, so as to filter the slurry, and the filter device is usually provided with filter core and filter screen. When the conveying pump 31 works for a long time, the filter core and filter screen in the filter device will be continuously impacted by the slurry. Therefore, through the cooperation of the timer 70 and the controller 80, the working of the conveying pump 31 conveying slurry is intermittent, which can not only meet the effect of slurry supplement, but also increase the buffering time of the filter core and filter screen in the filter device, so as to improve the service life of the conveying pump 31 and the service life of the filter core and filter screen.
