Working principle: When the irrigation water in the canal 400 enters the water inlet shell 1, it will flow through the water collecting cover 701. The flow of water can be used to drive the impeller 704 to rotate. The impeller 704 drives the rotating shaft 703 and the worm 705 to rotate synchronously. The worm 705 can drive The worm gear 707 meshed with it rotates, and the worm gear 707 can drive the transmission rod 706, the driving gear 708 and the driving synchronous wheel 709 to rotate synchronously. The driving synchronous wheel 709 drives the driven synchronous wheel 710 to rotate through the transmission synchronous belt 711, thereby causing the reciprocating screw 601 to rotate. The rotation of the reciprocating screw 601 can drive the threaded seat 602 threadedly connected with it to reciprocate vertically. The movement of the threaded seat 602 drives the grid 603 and the cleaning roller 605 to move vertically along the filter plate 4. The cleaning roller 605 can clean the filter during the movement. The outer surface of the screen plate 4 is cleaned to prevent it from clogging. The grid 603 can clean and collect the debris accumulated near the filter screen 4 during the movement.

Through the gear ring 902 provided on the outer wall of the turntable 901, the driving gear 708 rotates to drive the turntable 901 to rotate. The turntable 901 drives the rocker 903 to rotate synchronously, and the rocker 903 and the connecting rod 904 cooperate to drive the desludging assembly 8 as a whole on the beam 5. The upper level reciprocates to increase the dredging area of the dredging component 8, making the dredging effect better;

The silt discharge port 806 can be used to conveniently discharge the silt collected inside the silt collection box 801, and the blocking plate 807 can be used to block the silt discharge port 806 to avoid leakage of silt during the collection process. Use reset The elastic force of the initial state of the spring 810 can push the blocking plate 807 to move downward, ensuring that the blocking plate 807 can be stably inserted inside the silt collecting box 801. When the silt collecting box 801 moves forward to the maximum stroke, the second wedge-shaped block can be used The inclined surface between 813 and the first wedge block 811 causes the first wedge block 811 to move upward.

When the sliding rod 809 pushes the blocking plate 807 to move upward, The silt discharge port 806 is in the open state. When the silt discharge port 806 is in the open state, the silt collected inside the silt collection box 801 can be discharged to the guide plate 812, and then discharged to the field ridge 200 from the guide plate 812 to realize the control of the silt collection box. The effect of automatically discharging the silt collected in 801 can, on the one hand, increase the silt capacity inside the silt collection box 801, and on the other hand, facilitate the staff to clean the silt inside the silt collection box 801;

The linkage gear 104 can be driven to reciprocate synchronously inside the chute 101 during the horizontal reciprocating sliding process of the silt collection box 801 driven by the pushing assembly 9 on the beam 5. When the linkage gear 104 moves, it is rollingly meshed with the linkage rack 102, causing the linkage gear 104 to reciprocate synchronously. 104 is in a rotating state, the linkage gear 104 drives the linkage shaft 103 to rotate, the linkage shaft 103 drives the driving sprocket 105 to rotate, the driving sprocket 105 drives the driven sprocket 109 and the follower rod 106 to rotate through the linkage chain 110, and the follower rod 106 The driving bevel gear 107 drives the driven bevel gear 108 to rotate, the driven bevel gear 108 drives the rotating rod 803 to rotate, and the rotating rod 803 drives the conveying auger 804 to rotate, thereby achieving the effect of automatic cleaning and collection of sludge. When the silt collection box 801 is on the beam 5 moves forward, the elastic force of the support spring 1095 pushes the pawl 1094 to snap into the ratchet 1093, thereby fixing the movable wheel 1092 and the fixed wheel 1091, so that the driven sprocket 109 can drive the fixed wheel 1091 and the movable wheel 1091. The wheel 1092 rotates synchronously, so that the driven sprocket 109 can follow the driving sprocket 105 to rotate synchronously under the driving of the linkage chain 110. When the silt collection box 801 moves backward on the beam 5, the elastic force of the support spring 1095 can pull the ratchet. The pawl 1094 is separated from the ratchet 1093. At this time, the movable wheel 1092 can rotate synchronously with the driving sprocket 105 driven by the linkage chain 110, while the fixed wheel 1091 and the follower rod 106 will not rotate, thus causing the desilting assembly 8 The rotating rod 803 does not rotate during the backward movement, which can prevent the sludge conveyed on the conveying auger 804 from flowing back.
