[0014] The present invention provides an engineering mechanical device for river channel combing, which has the following beneficial effects:

[0015] (1) The invention, through the setting of the input device, drives the rotating shaft 1 to rotate through the rotating motor, and the rotation of the rotating shaft 1 drives the rotating roller 1 to rotate through the No. 1 belt, and the rotation of the rotating roller 1 drives the screen machine to work.

[0016] (2) In the present invention, by setting up a crushing device, the rotating roller 1 rotates and drives the rotating shaft 2 to rotate through the No. 3 belt. The garbage transported to the inside of the bracket will be crushed by the cutting blade. The crushed garbage will fall into the cylinder by gravity. The rotation of the rotating shaft 2 drives the auger to rotate, so as to transfer the garbage to the collection box. The driving paddle is driven by water flow to rotate. The driving paddle rotates and drives the rotating rod to rotate. The fixed rod and the receiving column drive the impact block to contact the impact plate to generate vibration. The vibration will be transmitted to the entire cylinder, so that the garbage remaining on the inner wall of the cylinder and the auger will fall down through the vibration and continue to be transported.

[0017] (3) In the present invention, by setting a cleaning device, water is filtered through a filter and then enters a water collection box. The water in the water collection box is transported to a water storage tank through a water pump along a water pipe. The water is transported to a water spray pipe by opening a pipe through an electromagnetic valve. After the cutting blade crushes the garbage, there will be garbage remaining on the blade or on the inner wall of the bracket. The cutting blade is cleaned through a water spray pipe to prevent the garbage from clogging or corroding the cutting blade, thereby reducing the working efficiency of the cutting blade. The L-shaped rod is driven to rotate by the three-axis rotation of the rotating shaft, and the rotation of the L-shaped rod drives the rotating knob to rotate. The rotation of the rotating knob drives the water spray pipe to rotate. The rotation of the water spray pipe expands the coverage of the water spray, so that the garbage remaining on the inner wall of the bracket is washed away, and the garbage is prevented from remaining on the bracket. The inner wall of the frame will be corroded, and some garbage will remain on the filter. By moving the pin upward, the T-shaped block will move to the right to cooperate with the connecting block and the No. 1 spring to make the groove of the filter free from the restriction of the inclined surface of the plug block. Only then can the filter be taken out for processing. When installing the filter, the plug block is moved to the right through the groove of the filter. The movement of the plug block will compress the No. 1 spring. When the groove and the plug block are at the same level, the No. 1 spring is released to move the plug block to the left until it is inserted into the groove, and the filter can be quickly installed. Quick installation and disassembly make it easier to regularly clean and maintain the filter. The filter needs to be cleaned or replaced regularly to ensure its efficiency and long life. The quick disassembly design can save maintenance time and reduce maintenance costs. BRIEF DESCRIPTION OF THE DRAWINGS
