Specifically, when the high-pressure spray nozzle moves left and right, the control mechanism controls the pneumatic motor 21 to work, the pneumatic motor 21 drives the transmission shaft 23 to rotate, so that the rack sliding device 24 at one end of the transmission shaft 23 slides on the rack, and the steel rail sliding device 25 at the other end slides on the steel rail, so that the high-pressure spray nozzle 56 moves left and right, and the post-cast strip is broken left and right.
During the forward and backward movement, the control mechanism controls the linear module 31 to work, the module slide block moves forward and backward, and the mounting fixing plate 33 mounted on the module slide block moves forward and backward, so that the rotary breaking mechanism 5 mounted on the mounting fixing plate 33 is driven to move forward and backward, the forward and backward movement of the high-pressure nozzle 56 on the rotary breaking mechanism 5 is realized, and the post-cast strip is broken forward and backward.
When the control mechanism moves up and down, the control mechanism controls the operation of the lifter 42, the lifter 42 operates to drive the bracket 43 to move up and down, and further drives the rotary breaking mechanism 5 on the bracket 43 to move up and down, so that the high-pressure spray nozzle 56 on the rotary breaking mechanism 5 can move up and down to break up the post-cast strip.
The foregoing shows and describes the general principles, essential features, and advantages of the utility model. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the utility model as claimed.
