DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-2 A river channel desilting sludge conveyor in this embodiment includes a shell 1, an observation window is inlaid on the outer wall of the front of the shell 1, a fixed block is fixed on the left side of the shell 1, a lifting mechanism 2 for lifting height is provided at the bottom of the shell 1, a base 3 is fixed on the right side of the lifting mechanism 2, and the base 3 is a groove-shaped plate with openings on the top and the right side.

[0028] It should be noted that the lifting mechanism 2 includes a connecting plate 201 fixed to the bottom of the outer shell 1, a supporting plate 202 is fixed to the bottom of the connecting plate 201, the inner movably connected to the supporting plate 202 is a slider 203 that penetrates to the outside thereof, sliding blocks are fixed to the front and rear sides of the slider 203, and the front and rear side walls of the inner cavity of the supporting plate 202 are provided with sliding grooves that are slidably connected to the sliding blocks. A lifting cylinder 204 is fixed to the left side of the connecting plate 201, the movable axis of the lifting cylinder 204 is fixed to the slider 203, and the right side of the slider 203 is fixed to the base 3.

[0029] It can be known that, under the driving action of the lifting cylinder 204, the height of the lifting mechanism 2 can be adjusted through the movable connection between the slider 203 and the support plate 202, which is beneficial to the cleaning of silt in rivers of different depths.

[0030] Furthermore, a pumping mechanism 4 for extracting mud and water is fixed on the base 3, and the pumping mechanism 4 includes a mud pump 401 fixed to the left inner wall of the base 3, and the bottom of the mud pump 401 is connected to a mud pumping pipe 402, and a support block is fixed to the top of the bottom plate of the base 3, and the top of the support block is fixed to the mud pumping pipe 402. The right opening size of the mud pumping pipe 402 matches the space between the front and rear plates of the base 3, and the top of the mud pump 401 is connected to a bellows 403. The setting of the bellows 403 is beneficial to the adaptive adjustment of the pipe length when the lifting mechanism 2 is active, which is beneficial to the stable operation of the device. The bellows 403 is connected to the mud delivery pipe 5, and the bottom of the outer shell 1 is connected to the mud delivery pipe 5 connected to the pumping mechanism 4.

[0031] Through the action of the mud pump 401, the sludge is sucked into the mud pumping pipe 402, and then transmitted into the interior of the shell 1 through the bellows 403. The design of the pumping mechanism 4 speeds up the speed of extracting the sludge, which is beneficial to improving the sludge cleaning efficiency.

[0032] It should also be noted that an outer frame 6 is fixed to the top of the outer shell 1, and a breaking mechanism 7 extending to the inner cavity of the outer shell 1 is provided on the top of the outer shell 1, and the breaking mechanism 7 is used to break up the sludge. A support plate 8 is fixed to the right side of the outer shell 1, and a mud box 9 fixed to the top of the support plate 8 is fixed to the right side of the outer shell 1. A connecting block is fixed to the left side of the mud box 9, and the connecting block is fixed to the outer shell 1. The inner cavity of the mud box 9 is movably connected with a filter plate 10, and connecting grooves compatible with the filter plate 10 are provided on the left and right side walls of the inner cavity of the mud box 9. The filter plate 10 is slidably connected to the connecting grooves, and an inspection door is hinged on the front of the mud box 9 and in front of the filter plate 10 through a hinge. The provision of the inspection door is conducive to the replacement of the filter plate 10, the normal operation of the device, and the stability of the device. A sealing layer is fixed at the gap between the inspection door and the mud box 9. The provision of the sealing layer is conducive to preventing the leakage of sludge and ensuring the stable operation of the device.

[0033] In addition, a conveying mechanism 11 is provided on the top of the mud box 9, which is respectively connected to the outer shell 1 and the inner cavity of the mud box 9. The conveying mechanism 11 includes a conveying pump 1101 fixed to the top of the mud box 9. The left side of the conveying pump 1101 is connected to a mud delivery pipe 1102, which passes through the outer shell 1 and extends to the inner cavity of the outer shell 1. The right side of the conveying pump 1101 is connected to a mud transfer pipe 1103, which passes through the mud box 9 and extends to the inner cavity of the mud box 9. The conveying mechanism 11 is used for the transmission of mud and water.

[0034] In addition, by supplying energy through the transfer pump 1101, the broken up sludge passes through the sludge delivery pipe 1102 and the sludge transfer pipe 1103 more quickly, thereby speeding up the efficiency of the sludge entering the sludge storage box 9, which is beneficial to speeding up the sludge transmission efficiency, thereby improving the dredging efficiency.

[0035] It can be understood that the bottom of the mud box 9 is connected to a water outlet pipe 12, and the inside of the water outlet pipe 12 is slidably connected to a filter layer composed of activated carbon. The inner wall of the water outlet pipe 12 is provided with a mounting groove connected to its top surface, and the filter layer is movably installed in the mounting groove. A mud discharge door 13 is hinged on the right wall of the mud box 9. The hinge force of the mud discharge door 13 is large, and a certain thrust to the right is required to push the mud discharge door 13 open. When a lot of sludge remains on the filter plate 10, the sludge will open the mud discharge door 13 under the push of the pushing mechanism 14. This design is conducive to increasing the residence time of the sludge on the filter plate 10, which is conducive to improving the penetration effect of water, reducing the moisture in the sludge, and thereby improving the dredging effect. A pushing mechanism 14 for discharging sludge is fixed on the inner cavity wall of the sludge holding box 9.

[0036] In this embodiment, the device is adjusted through the lifting mechanism 2, and the pumping mechanism 4 is used to extract the sludge. After the sludge is transferred to the outer shell 1, the sludge is dispersed by the dispersion mechanism 7, which is beneficial to the subsequent water penetration of the sludge. The water is then discharged through the penetration effect of the filter plate 10 and the water outlet pipe 12, and then the sludge is pushed out by the pushing mechanism 14. In this process, the sludge is dispersed in advance by the dispersion mechanism 7, which is beneficial to the subsequent transmission of the sludge and accelerates the penetration efficiency of water in the sludge, thereby improving the dredging efficiency and further improving the dredging effect.

[0037] See also Figure 3 In order to improve the dredging efficiency and accelerate the separation of sludge and water, the breaking mechanism 7 in this embodiment includes a servo motor 701 fixed to the top of the housing 1 and located in the inner cavity of the outer frame 6. The output shaft of the servo motor 701 is fixed with a driving gear 702. A sealed bearing 703 is fixed in the wall at the top of the housing 1. A sleeve rod 704 is fixed at the axis of the sealed bearing 703, and both ends thereof penetrate into the inside and outside of the housing 1 respectively. The sealed bearing 703 prevents external dust, sludge, water flow and other impurities from invading the bearing, thereby preventing the leakage of grease. It plays a good supporting role on the sleeve rod 704 and improves the stability of the device. The sleeve rod 704 is internally movably connected with a rotating rod 705 that penetrates the sleeve rod 704. The upper and lower sides of the driving gear 702 are meshed with driven gears 706 that are arranged opposite to each other. The upper and lower driven gears 706 are respectively fixed on the outer surfaces of the rotating rod 705 and the sleeve rod 704. The outer surface of the rotating rod 705 is fixed with a plurality of stirring blades 707 located in the inner cavity of the shell 1, and the outer surface of the sleeve rod 704 is fixed with a stirring frame 708 located in the inner cavity of the shell 1.

[0038] In this embodiment, the servo motor 701 supplies energy, and under the cooperation of the driving gear 702 and the driven gear 706, the stirring blade 707 and the stirring frame 708 rotate in opposite directions, thereby improving the effect of breaking up the sludge and thus accelerating the dredging efficiency.

[0039] See also Figure 4In order to discharge the accumulated silt, the pushing mechanism 14 in this embodiment includes a pushing cylinder 1401 fixed to the left side wall of the inner cavity of the mud box 9, and the output shaft of the pushing cylinder 1401 is fixed with a connecting plate 1402, and a pushing plate 1403 is fixed to the right side of the connecting plate 1402. A mud shoveling block 1404 is fixed to the bottom of the right side of the pushing plate 1403. The mud shoveling block 1404 is a sloped structure with the left side higher and the right side lower. The setting of the mud shoveling block 1404 is conducive to pushing the silt more easily when the pushing plate 1403 moves to the right, which is conducive to the discharge of silt and improves the dredging efficiency. The bottom surfaces of the pushing plate 1403 and the mud shoveling block 1404 are in contact with the top surface of the filter plate 10.

[0040] In this embodiment, the push cylinder 1401 provides thrust. Under the fixing action of the plate, the push plate 1403 and the shoveling block 1404 move to the right. The slope setting of the shoveling block 1404 helps to discharge the silt out of the device, thereby helping to improve the dredging efficiency.

[0041] The electrical components appearing in the text are all electrically connected to the controller and the power supply. The control method of the utility model is controlled by the controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power supply is also common knowledge in this field. The utility model is mainly used to protect mechanical devices, so the utility model will no longer explain the control method and circuit connection in detail.

[0042] The working principle of the above embodiment is:

[0043] (1) Start the lifting cylinder 204 to adjust the depth of the base 3 at the riverbed, then start the mud pump 401, and extract the sludge to the riverbed under the action of the pump force, and transmit it to the inner cavity of the shell 1 through the bellows 403 and the mud delivery pipe 5, and then start the servo motor 701, so that the driving gear 702 starts to rotate, thereby driving the driven gear 706 to rotate. Due to the placement state of the two driven gears 706, the two driven gears 706 rotate in opposite directions, prompting the sleeve rod 704 and the rotating rod 705 to rotate in opposite directions, so that the stirring blade 707 and the stirring frame 708 rotate in opposite directions, which is conducive to accelerating the speed of breaking up the sludge, improving the breaking effect, and thus improving the sludge transmission efficiency, and the dredging efficiency is high.

[0044] (2) After the sludge is broken up in the outer shell 1, the sludge is conveyed into the sludge holding box 9 through the sludge delivery pipe 1102 and the sludge transfer pipe 1103 by the pumping force of the transmission pump 1101, and is allowed to stand so that the filtrate flows out through the filter plate 10 and the outlet pipe 12 in turn, and then the pushing cylinder 1401 is started. Under the action of the thrust, the pushing plate 1403 and the shoveling block 1404 move to the right, and the sludge is pushed out from the sludge discharge door 13 under the thrust. The overall structure is simple, and the water content in the sludge is effectively reduced, thereby achieving the purpose of good dredging effect.
