[0002] Southern my country is an area prone to frequent floods. During the summer flood season every year, rising water levels cause rivers and canals to overflow. After the flood season, a lot of silt will be deposited at the bottom of the canals, resulting in a reduction in the cross-sectional area of ​​the canals where water can flow, affecting the flow of the canals and making it difficult to use the canals. Therefore, dredging equipment is generally needed to dredge the canals after the flood season.

[0003] In the related technology, a Chinese utility model patent with publication number CN216075300U proposes a post-flood emergency river channel desilting device. The first motor is started to drive the screw to rotate, so that the L-shaped rod slowly descends, allowing the sludge suction head to penetrate into the silt, and the external power supply of the sludge suction pump is connected to start sucking the silt. Compared with traditional manual sludge salvage, it is more convenient and labor-saving.

[0004] The above-mentioned related technologies have the following defects: after the flood season, in addition to silt, there will also be some larger garbage brought by the impact of the flowing water at the bottom of the river channel. If only a sludge pump is used for extraction and dredging, on the one hand, the sludge pump is easily clogged by the larger garbage sucked in; on the other hand, the extraction and dredging speed of the sludge pump is slow, resulting in a long time for dredging the river bottom.

[0019] The technical solution of the present application will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.

[0020] The present application embodiment discloses a post-flood emergency canal dredging device. Figure 1 and Figure 2 A post-flood emergency canal dredging device includes one or two groups of steering lifting mechanisms 10, a sliding part 20 and a dredging bucket 30. The sliding part 20 is connected and arranged below the steering lifting mechanism 10, and the sliding part 20 can slide along the steering lifting mechanism 10, and the dredging bucket 30 is installed and fixed below the sliding part 20, so that the movable sliding part 20 can adjust the position state of the dredging bucket 30, and it can be adjusted to a horizontal state or a vertical state. In this embodiment, the steering lifting mechanism 10 is set to two groups, and the two groups of steering lifting mechanisms 10 are symmetrically arranged on the opposite sides of the sliding part 20 and are both connected to the sliding part 20, so that the sliding part 20 can be stably supported by the two groups of steering lifting mechanisms 10 to move.

[0021] See also Figure 3The steering lifting mechanism 10 includes a guide bracket 11, a hydraulic cylinder 12, a lifting arm 13 and a connecting arm 14. The bottom of the hydraulic cylinder 12 is rotatably connected to the lower end of the guide bracket 11, the top of the lifting arm 13 is rotatably connected to the upper end of the guide bracket 11, and a protruding arm 131 protruding outward is formed on the top outer wall of the lifting arm 13. The output end of the hydraulic cylinder 12 is rotatably connected to the protruding arm 131, so that when the output end of the hydraulic cylinder 12 is extended or retracted, the protruding arm 131 can be pushed to drive the lifting arm 13 to deflect on the guide bracket 11. The lower end of the lifting arm 13 is rotatably connected to the adjacent end of the connecting arm 14, so that when the lifting arm 13 deflects, the connecting arm 14 can be driven to move accordingly. The other end of the connecting arm 14 is rotatably connected to the sliding part 20, and the top of the sliding part 20 is slidably connected to the guide bracket 11. When the connecting arm 14 moves, it can push the sliding part 20 to slide along the guide bracket 11, thereby adjusting its position state.

[0022] In this embodiment, the guide bracket 11 may include a vertical section 111, a transverse section 112, a guide groove 113, a tripod 114, and a fixing plate 115. The transverse section 112 and the vertical section 111 are fixedly connected to form an "L" shape, the guide groove 113 is formed on the vertical section 111 and the transverse section 112, and the shape of the guide groove 113 is the same as the shape formed by the vertical section 111 and the transverse section 112. The sliding part 20 is slidably connected to the guide bracket 11 by using the guide groove 113, so that the guide groove 113 and the sliding part 20 cooperate to guide the moving track of the dredging bucket 30. The tripod 114 is formed at the lower end of the outer wall of the vertical section 111, and the tripod 114 is rotatably connected to the hydraulic cylinder 12. The guide bracket 11 also includes a fixing plate 115, which is formed on the top of the vertical section 111 and protrudes outward. A plurality of fixing holes are formed on the fixing plate 115. When the equipment as a whole is installed, the steel frame structure can be supported under the fixing plate 115, and the two can be connected by fasteners such as bolts or rivets passing through the fixing holes, and the bottom support of the steel frame structure is fixed on a carrying equipment such as a hull or a vehicle body, so that the equipment as a whole can be driven to move.

[0023] See also Figure 4 The sliding part 20 includes a slide, connecting ears 24 and a connecting frame 25, which are equal in number to the steering and lifting mechanism 10. The side of the slide extends into the guide groove 113 and is slidably connected thereto. The connecting ears 24 are formed at the bottom of the slide and are rotatably connected to the adjacent connecting arms 14, so that the sliding part 20 can move along the guide groove 113 under the drive of the connecting arms 14. The connecting frame 25 is welded and fixed below the bracket 21, and the dredging bucket 30 is installed and fixed at the bottom of the connecting frame 25 so that it supports the dredging bucket 30.

[0024] In this embodiment, the slide comprises a bracket 21, two convex shafts 22, and rollers 23 sleeved on the ends of the convex shafts 22. The two convex shafts 22 are respectively inserted on the left and right sides of the bracket 21 and are fixedly connected to the bracket 21. The rollers 23 sleeved on the ends of the convex shafts 22 are rotatably connected to the convex shafts 22, and the rollers 23 on the same side extend into the adjacent guide grooves 113. The outer diameter of the rollers 23 is adapted to the width of the guide grooves 113, so that when the slide is driven to move, the rollers 23 can rotate in the guide grooves 113 and assist the movement and steering of the slide.

[0025] See also Figure 1 and Figure 2 The dredging bucket 30 is detachably fixed under the connecting frame 25, and an intake port 31 communicating with the inner cavity of the dredging bucket 30 is formed on the left side of the dredging bucket 30, and a plurality of drainage holes 32 are formed on at least one outer wall of the dredging bucket 30. When the equipment is driven to move by the transport equipment, the dredging bucket 30 can be placed in a horizontal state and sunk to the river bottom, and the intake port 31 is oriented in the moving direction, so that when the transport equipment moves, the silt and garbage can be collected into the inner cavity of the dredging bucket 30 at the intake port 31. After the dredging bucket 30 is driven to a vertical state, it can be moved out of the water, and the water in its inner cavity can flow out through the drainage holes 32, and the staff can clean the garbage and silt inside it from the intake port 31.

[0026] In all the schemes mentioned above, the connection between two parts can be selected according to actual conditions by welding, bolt and nut matching connection, bolt or screw connection or other well-known connection methods, which are not described one by one here. In the above, all fixed connections are preferably welded. Although the embodiments of the utility model have been shown and described, it can be understood by ordinary technicians in this field that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the utility model. The scope of the utility model is defined by the attached claims and their equivalents.
