[0023] An embodiment of the present application discloses a channel dredging device.
[0024] Reference Figure 1 With Figure 2 The channel dredging device comprises a box 1, a screw rod 2, a collection vehicle 3, a driving assembly 4, a lifting assembly 5 and a transportation assembly 6. The box 1 is hollow inside and vertically welded with a partition 11. In this embodiment, the partition 11 can be made of a 10cm thick plate. The partition 11 divides the inner cavity of the box 1 into a square chamber and a cylindrical chamber. An inlet 12 is formed at the lower end of the box 1 and communicates with the cylindrical chamber of the box 1. The screw rod 2 is vertically and rotatably installed at the bottom of the cylindrical chamber of the box 1 through a bearing. The bearing is sealed, and the lower end of the screw rod 2 is arranged close to the inlet 12. A plurality of helical blades are spirally arranged on the screw rod 2 in the circumferential direction. The collection vehicle 3 is horizontally placed in the square chamber of the box 1. The collection vehicle 3 is hollow inside and has an open upper end. The box 1 is rotatably connected with a wheel 7 at the bottom.
[0025] The driving assembly 4 is arranged on one side of the box 1 and connected with the screw rod 2. The driving assembly 4 is used to drive the screw rod 2 to rotate and lift the sludge.
[0026] Reference Figure 1 With Figure 2The box 1 is provided with a moving-out port 13 above the collecting vehicle 3 for moving out the collecting vehicle 3, and the moving-out port 13 at the upper end of the box 1 is larger than the size of the collecting vehicle 3. The partition plate 11 is provided with a pollution transmission port 14 at the upper end, which is square in this embodiment. A sludge guide slope 15 is provided at the lower edge of the pollution transmission port 14 for guiding the sludge lifted to the upper end of the spiral rod 2 into the collecting vehicle 3. The sludge guide slope 15 is lower near the side of the collecting vehicle 3, and the opening of the collecting vehicle 3 is below the lowest part of the sludge guide slope 15, so that the collecting vehicle 3 can collect the sludge lifted by the spiral rod 2.
[0027] The lifting assembly 5 is fixed to the upper end of the box 1 and above the collecting vehicle 3. In this embodiment, a lifting ring is welded at each of the four corners of the opening at the upper end of the collecting vehicle 3. When the collecting vehicle 3 collects a certain amount of sludge, the lifting assembly 5 can be detachably connected to the lifting ring and move the collecting vehicle 3 out of the moving-out port 13 of the box 1.
[0028] The transportation assembly 6 is arranged on the upper surface of the box 1 and is slidingly connected to the moving-out port 13. Two groups of pulleys are rotatably connected to the bottom of the collecting vehicle 3 through bearings. When the lifting assembly 5 moves the collecting vehicle 3 out of the moving-out port 13 of the box 1, the transportation assembly 6 is slid to the moving-out port 13, and then the transportation assembly 6 is adjusted to extend and lap on the side of the channel, so that the collecting vehicle 3 can be moved to the side of the channel, and the sludge in the collecting vehicle 3 is removed.
[0029] Through the above arrangement, the spiral rod 2 is driven by the driving assembly 4 to lift the sludge to the pollution transmission port 14 and fall into the collecting vehicle 3. The collecting vehicle 3 is moved out by the lifting assembly 5 and moved to the side of the channel by the transportation assembly 6, so that the manual use of a shovel for dredging is replaced, the labor intensity is reduced, and the dredging efficiency is improved.
[0030] Referring to Figure 1 and Figure 3 The driving assembly 4 includes a worm 41, a worm gear 42, and a servo motor 43. The worm gear 42 is coaxially fixed with the upper end of the spiral rod 2. The servo motor 43 is fixedly installed on the outer wall of the box 1 by bolts, and the output end of the servo motor 43 extends into the inner cavity of the box 1 and is coaxially fixed with the worm 41. The worm 41 is engaged with the worm gear 42. The servo motor 43 drives the worm 41 and the worm gear 42 to rotate the spiral rod 2. It should be noted that the worm 41 and the worm gear 42 are located in a separate space in the inner cavity of the box 1, so that the channel for conveying sludge formed by the worm 41, the worm gear 42, and the spiral rod 2 is isolated.
[0031] Referring to Figure 1The lifting assembly 5 comprises two air cylinders 51, a support beam 52, a winch 53, a hook 54, a traction rope 55 and four groups of hook ropes 56. The two air cylinders 51 are fixedly installed on the two sides of the box body 1 by bolts. The air cylinders 51 are vertically arranged, and the telescopic rods thereof are upwardly arranged. The support beam 52 is fixedly connected with the telescopic rods of the air cylinders 51 at both ends by bolts. In the embodiment, the support beam 52 is in a portal frame structure. The winch 53 is a common hoisting device for lifting or dragging heavy objects. The winch 53 is fixedly installed in the middle of the support beam 52 by bolts. In the embodiment, the outer wall of the box body 1 is further provided with an air pump for supplying air to the air cylinders 51. The telescopic rods of the air cylinders 51 are controlled to be extended or retracted by the air pump, so as to control the lifting of the support beam 52. One end of the traction rope 55 is fixed to the outer side wall of the winch 53, and the other end is connected to the hook 54. In the embodiment, one end of each of the four groups of hook ropes 56 is bundled and connected and hung on the hook 54. The hook ropes 56 are fixed with hooks at the ends, and the hooks are detachably and hookingly connected in the lifting ring at the upper end of the collection vehicle 3. The traction rope 55 is wound and unwound by the rotation of the winding drum of the winch 53, so as to control the lifting or lowering of the collection vehicle 3.
[0032] With reference to Figure 1 and Figure 4 The transportation assembly 6 comprises a moving plate 61, a transportation plate 64 and two groups of grading assemblies 62. In the embodiment, the moving plate 61 is slidably connected with the upper surface of the box body 1, and the sliding manner is that the sliding rails and sliding blocks of the prior art are matched with each other to slide. The transportation plate 64 is fixedly connected with the upper surface of the moving plate 61 by bolts and is in a position corresponding relationship. The transportation plate 64 is square and is hollow inside. Meanwhile, the end of the transportation plate 64 towards the two sides of the channel is open. In the embodiment, the two groups of grading assemblies 62 are slidably arranged in the inner cavity of the transportation plate 64, and can respectively slide outwards towards the two end openings of the transportation plate 64, so that the two groups of grading assemblies 62 are overlapped on the two sides of the channel.
[0033] The grading assembly 62 comprises a plurality of grading plates 621, which are square and hollow inside, and are arranged in a gradually decreasing size, and are arranged in a sliding manner one inside another. In this embodiment, the sliding manner between the grading plates 621 and the inner cavity of the transport plate 64 is that the two inner walls of the transport plate 64 are provided with sliding grooves, and the two side edges of the grading plate 621 are fixedly connected with sliding blocks which are slidably arranged in the sliding grooves. The sliding blocks are cylindrical and arranged at the end of the grading plate 621 close to the inner cavity of the transport plate 64. Similarly, the sliding manner between the inner grading plate 621 and the outer grading plate 621 is also the above-mentioned sliding manner. In this way, the inclination angle of each grading plate 621 in the vertical direction can be adjusted, so that the end grading plate 621 can be lapped on the channel bank, and then the collecting vehicle 3 is placed on the transport plate 64, and the collecting vehicle 3 can be moved along the grading plate 621 on one side to the channel bank.
[0034] The grading plate 621 is hingedly connected with a square guard plate 63 for preventing the collecting vehicle 3 from sliding out of the grading plate 621. The maximum unfolding angle of the guard plate 63 is 120°, and the thickness of the inner cavity of the outer grading plate 621 is greater than the total thickness of the guard plate 63 and the inner grading plate 621, so that the guard plate 63 can be folded into the inner cavity of the outer grading plate 621.
[0035] In this embodiment, the axis of the pulley of the collecting vehicle 3 is perpendicular to the extension direction of the transport plate 64. In order to make the sludge more smoothly enter the inlet 12, the lower edge of the inlet 12 extends an outwardly inclined extension plate 8, and the two sides of the inlet 12 extend a sludge guide plate. In order to make the wheels 7 of the box 1 more smoothly roll on the sludge ground, anti-skid protrusions are arranged on the surface of the wheels 7 of the box 1, thereby increasing the friction. A handrail is welded on the upper end of the side of the box 1 away from the inlet 12.
[0036] The implementation principle of the embodiment is: when it is necessary to clean the channel silt, first, the device is placed in the channel, then the box 1 is manually pushed to make the silt in the channel enter the pollution inlet 12, the screw rod 2 is controlled by the servo motor 43 to complete the lifting of the silt, and the silt falls into the collecting vehicle 3 from the pollution outlet 14; when it is necessary to clean the silt in the collecting vehicle 3, the hook rope 56 is connected with the lifting ring at the upper end of the collecting vehicle 3, the air cylinder 51 is supplied with air by the air pump, the telescopic rod of the air cylinder 51 lifts the winch 53 on the supporting beam 52, the winch 53 is started, the traction rope 55 is wound by the rotation of the winch 53, the lifting hook 54 is lifted, the collecting vehicle 3 is moved out of the box 1 under the action of the hook rope 56, and the collecting vehicle 3 is located above the box 1, then the sliding transport plate 64 is moved to below the collecting vehicle 3, the winch 53 is rotated in the opposite direction, the collecting vehicle 3 is stably placed on the transport plate 64, the hook rope 56 connected with the lifting ring at the upper end of the collecting vehicle 3 is detached, the transport plate 64 is moved away from the air cylinder 51, then the grading assembly 62 in the transport plate 64 is pulled out, the inner grading plate 621 is lapped on the side of the channel, the square guard plate 63 on the grading plate 621 is unfolded, then the collecting vehicle 3 is manually pushed to make the collecting vehicle 3 transported along the conveying channel formed by the plurality of grading plates 621 to the channel bank to be poured, the manual carrying is reduced, and the dredging efficiency is improved.
