Description

Technical Field

[0001] The present invention relates to the technical field of river dredging, and in particular to intelligent river dredging equipment for urban and rural construction. Background Art

[0002] As society develops, more and more domestic waste is generated, and some of this waste is dumped into rivers, causing pollution. Existing technologies typically plant aquatic plants in rivers to purify the water through their roots, absorbing pollutants. However, aquatic plants reproduce rapidly and, if left unchecked, can quickly cover the water surface, leading to oxygen depletion, damaging biodiversity, and even blocking the river's ability to carry floodwaters. Therefore, regular cleaning and dredging are necessary.

[0003] Traditionally, municipal rivers are mostly cleared by sanitation workers, and it is common to use a scoop net to pick up garbage one by one at the riverside. The cleaning efficiency is very low and the labor intensity is high. Sometimes, when encountering a large area of ​​aquatic plants, it is difficult to clean them with a scoop net. Moreover, the aquatic plants deeper in the river cannot be seen clearly due to the turbidity of the river water, and some of them are missed, which affects the effect of dredging the river.

DETAILED DESCRIPTION

[0038] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0039] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention.

[0040] like Figures 1 to 4 As shown, this embodiment proposes an intelligent river dredging device for urban and rural construction, including a hull 1, and also includes: a mounting plate 2, a collection grid 3 and a displacement mechanism. Two mounting plates 2 are provided and are respectively arranged on both sides of the front end of the hull 1. A waterweed removal mechanism for removing waterweed is provided on the mounting plate 2. The collection grid 3 is slidably connected to the front side of the hull 1 and is used to collect waterweed removed by the waterweed removal mechanism. The displacement mechanism is provided on the hull 1 and is used to drive the collection grid 3 to move back and forth relative to the hull 1. A transmission part is provided between the displacement mechanism and the waterweed removal mechanism.

[0041] In order to dredge the river and clean the aquatic plants in the river, the hull 1 travels in the river, and the aquatic plant removal mechanism at the front end of the hull 1 integrates aquatic plant pulling, clamping, cutting and transporting, thereby realizing automatic cleaning of aquatic plants in the river, achieving the goal of eliminating the need for manual salvaging of the entire aquatic plant cleaning process, and effectively avoiding the situation where the aquatic plants are missed and cannot be effectively removed by the existing weed removal equipment due to the shaking of the aquatic plants in the water body, thereby ensuring the efficiency and effect of river dredging and cleaning, and the displacement mechanism drives the aquatic plant removal mechanism to move through the transmission part, collecting The grid 3 moves back and forth between the hull 1 and the aquatic plant removal mechanism, so that when the aquatic plant removal mechanism transfers and releases the aquatic plants, the collecting grid 3 can receive the fallen aquatic plants. As the aquatic plant removal mechanism continues to rotate, the collecting grid 3 moves toward the hull 1 to prevent the collecting grid 3 from hindering the rotation of the removal structure that has released the aquatic plants, so that the various structures cooperate and relate to each other to achieve coordinated movement, making the aquatic plant cleaning process more coherent and smooth. At the same time, the collecting grid 3 moves back and forth, which can effectively evenly lay the aquatic plants that fall into the collecting grid 3, thereby ensuring the storage capacity of the collecting grid 3.

[0042] like Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 、 Figure 12 and Figure 13 As shown, as a preferred embodiment, based on the above-mentioned embodiment, the waterweed removal mechanism further includes a rotating tube 4 rotatably connected to the mounting plate 2 and a plurality of groups of removal components 5 equidistantly distributed along the axial direction of the rotating tube 4. Each group of removal components 5 includes a plurality of plucking portions 501 evenly distributed on the circumference of the rotating tube 4 and a fixing rod 502 cooperating with the plucking portions 501. The fixing rod 502 is fixedly connected to the rotating tube 4.

[0043] When the aquatic weed removal mechanism is working, the rotating tube 4 rotates relative to the mounting plate 2, and the rotating tube 4 drives the removal component 5 to rotate in a circle. The pulling portion 501 in the removal component 5 cooperates with the fixing rod 502 to achieve the effects of pulling, clamping, cutting and transporting the aquatic weeds, effectively avoiding the situation where the aquatic weeds are missed and the situation where the existing weed removal equipment cannot effectively remove the aquatic weed roots due to the swaying of the aquatic weeds in the water body, thereby ensuring the efficiency and effect of river dredging and cleaning;

[0044] It should be noted that the removal portion 501 includes a fixed tube 5011 fixedly mounted on the rotating tube 4, a connecting rod 5012 fixedly connected to the fixed tube 5011, a guide housing 5013 fixedly connected to the connecting rod 5012, pressure plates 5014 rotatably connected to both sides of the connecting rod 5012 and disposed in the guide housing 5013, and a toggle assembly disposed in the fixed tube 5011 for driving the two pressure plates 5014 away from each other. A torsion spring is disposed between the two pressure plates 5014 and the connecting rod 5012, and the pressure plates 5014 movably abut against the fixed rod 502.

[0045] Furthermore, the fixed rod 502 is provided with an extrusion surface that movably contacts the pressure plate 5014. The pressure plate 5014 includes a main body 6 rotatably connected to the connecting rod 5012 and a movable plate 601 rotatably connected to the main body 6 via a pin. The main body 6 is provided with a movable groove 602 for the movable plate 601 to move. A first elastic element 6021 is provided between the inner wall of the movable groove 602 and the movable plate 601. A cutter 6022 is fixedly provided on the inner wall of the movable groove 602 to movably contact the extrusion surface.

[0046] Furthermore, the toggle assembly includes a toggle rod 7 movably connected to the fixed tube 5011, a connecting rod 701 fixedly connected to the toggle rod 7, and a slider 702 movably connected to the end of the connecting rod 701 via a pin. The pressure plate 5014 is provided with a chute 7021 for sliding the slider 702. Both ends of the chute 7021 are provided with openings. The openings facilitate the automatic expulsion of debris entering the chute 7021 when the slider 702 moves, thereby preventing debris from accumulating in the chute 7021 and affecting the normal movement of the slider 702.

[0047] When the cleaning component 5 is placed in the water body, the front end of the guide shell 5013 can guide the water body and the aquatic plants, reduce the movement resistance of the hull 1, and distribute the aquatic plants to the gap formed between the fixed rod 502 and the cleaning component 5, so as to avoid the aquatic plants being missed; when the toggle component works, the toggle rod 7 rotates relative to the fixed tube 5011, so that the toggle rod 7 drives the connecting rod 701 to rotate, and the connecting rod 701 drives the slider 702 to slide in the slide groove 7021 of the pressure plate 5014, and the connecting rod 701 pushes the pressure plates 5014 on both sides of the guide shell 5013 to separate from each other, and the pressure plates 5014 move toward the fixed rod 502 on the side. 5014 cooperates with the extrusion surface on the fixed rod 502 to clamp the water plants; and as the rotating tube 4 continues to rotate, the clamped water plants move upward, and the roots of the water plants are straightened, which is convenient for the subsequent cleaning components 5 to clean the straightened roots; as the rotating tube 4 rotates, the pressure plate 5014 continues to move toward the fixed rod 502, and the movable plate 601 is forced to shrink into the movable groove 602, so that the cutter 6022 leaks out and cuts the clamped water plants; and after the water plants are cut, the movable plate 601 still cooperates with the extrusion surface to clamp the cut water plants; as the rotating tube 4 rotates, the movable plate 601 eventually no longer contacts the extrusion surface, and the cut water plants automatically fall off. At this time, the collecting grid 3 placed on the lower side automatically picks up the fallen aquatic plants; then the displacement mechanism drives the collecting grid 3 to move toward the hull 1 to prevent the collecting grid 3 from hindering the rotation of the cleaning component 5 that has released the aquatic plants; after the cleaning component 5 passes over the collecting grid 3, the displacement mechanism drives the collecting grid 3 to move toward the rotating tube 4, so that the collecting grid 3 picks up the aquatic plants released by the next cleaning component 5; then after the cleaning component 5 rotates into the water body, the aquatic plants are clamped, cut and transported repeatedly.

[0048] like Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 and Figure 9 As shown, as a preferred embodiment, on the basis of the above-mentioned manner, further, an arc block 401 is fixedly provided in the rotating tube 4, and a first arc surface 4011 and a guide surface 4012 are provided on the arc block 401, which are movably abutted against the end of the toggle rod 7, and a second arc surface 4013 is not movably abutted against the end of the toggle rod 7. The outer side of the toggle rod 7 is rotatably connected to the annular plate 703 through a bearing, and a groove 704 for sliding of the annular plate 703 is provided in the fixed tube 5011, and a second elastic element 7041 is fixed between the inner wall of the groove 704 and the annular plate 703. The fixed tube 5011 is fixedly provided with a fixed block 8, and a track groove 705 for sliding of the fixed block 8 is provided on the toggle rod 7. The track groove 705 consists of a spiral groove 7051 and a flat groove 7052 arranged horizontally along the axis of the toggle rod 7, and the spiral groove 7051 and the flat groove 7052 are connected to each other.

[0049] When the rotating tube 4 drives the cleaning component 5 to rotate, the toggle rod 7 rotates relative to the arc block 401. When the toggle rod 7 rotates to the guide surface 4012 area, the end of the toggle rod 7 begins to gradually abut against the arc block 401. The toggle rod 7 moves in the direction away from the rotating tube 4 during the abutment process. The second elastic element 7041 is compressed, and under the cooperation of the fixed block 8 and the spiral groove 7051, the toggle rod 7 rotates relative to the fixed tube 5011 when it moves, so that when the toggle rod 7 rotates, the connecting rod 701 and the slider 702 push the pressure plate 5014 to flip, so that the pressure plate 5014 cooperates with the fixed rod 502 to clamp, pull and cut the water plants. Cutting; As the rotating tube 4 rotates, the end of the toggle rod 7 abuts against the first arc surface 4011, and at this time the fixed block 8 is placed in the flat groove 7052 instead of the spiral groove 7051, and the toggle rod 7 no longer rotates and maintains the clamping state of the cut waterweed; when the cleaning component 5 clamps the cut waterweed and moves to the upper side of the collecting grid 3, the end of the toggle rod 7 rotates to the second arc surface 4013 area, and the toggle rod 7 is reset under the push of the second elastic element 7041, and the pressing plate 5014 no longer cooperates with the fixed rod 502 to clamp the cut waterweed, and the cut waterweed automatically falls into the collecting grid 3 on the lower side; It should be noted that, Figure 8 As shown, the toggle rod 7 is composed of a rod body that moves in the fixed tube 5011, a rod body fixedly connected to the connecting rod 701, and a telescopic tube arranged between the two rod bodies. The telescopic tube is used to transmit the torque between the two rod bodies, and the telescopic tube can automatically extend and retract when the rod body in the fixed tube 5011 moves laterally, avoiding the lateral movement of the rod body connected to the connecting rod 701, which causes the slider 702 to be misaligned with the slide groove 7021 on the pressure plate 5014.

[0050] like Figure 1 、 Figure 2 、 Figure 10 and Figure 11 As shown, as a preferred embodiment, based on the above embodiment, the displacement mechanism further includes a displacement motor 9 fixed in the hull 1, a rotating member 10 connected to the output shaft of the displacement motor 9, and a sleeve 11 threadedly connected to the rotating member 10, and the sleeve 11 is connected to the collection grid 3;

[0051] When the displacement mechanism is working, the displacement motor 9 runs, the output shaft of the displacement motor 9 drives the rotating member 10 to rotate, and the sleeve 11 threadedly connected to the rotating member 10 moves along the axial direction of the rotating member 10, so that the sleeve 11 drives the collecting rack 3 to reciprocate;

[0052] It should be noted that the rotating member 10 includes two crank shafts 1001 and a reciprocating screw 1002 arranged between the two crank shafts 1001, one of the crank shafts 1001 is connected to the output shaft of the displacement motor 9, the sleeve 11 is threadedly connected to the reciprocating screw 1002, and the reciprocating screw 1002 is coaxially arranged with the two crank shafts 1001; the arrangement of the reciprocating screw 1002 enables the displacement motor 9 to achieve reciprocating movement of the collection grid 3 without changing the rotation direction, while ensuring that the rotating tube 4 drives the cleaning component 5 to always rotate in the same direction to clean the aquatic plants;

[0053] Furthermore, a swinging member 13 is rotatably connected to the crank shaft 1001, and one end of the swinging member 13 away from the crank shaft 1001 is movably connected to a movable rod 131, and the upper end of the movable rod 131 is movably connected to a movable plate 132, and an elastic telescopic rod 133 is provided on the lower side of the movable plate 132, and the end of the elastic telescopic rod 133 away from the movable plate 132 is connected to a lower pressure plate 134; when the crank shaft 1001 rotates with the reciprocating screw rod 1002 as the center of the circle, the crank shaft 1001 drives the swinging member 13 and the movable rod 131 to move, so that the movable rod 131 drives the movable plate 132 to move back and forth. When the movable plate 132 moves up and down, the elastic telescopic rod 133 drives the lower pressure plate 134 to squeeze the aquatic plants in the collecting grid 3. On the one hand, it prevents the aquatic plants from becoming fluffy and occupying too much storage space of the collecting grid 3. On the other hand, it can filter the water in the aquatic plants, reduce the water content in the aquatic plants, increase the single aquatic plant transportation volume, and reduce the subsequent difficulty and transportation cost of aquatic plants. The setting of the elastic telescopic rod 133 can prevent the movable plate 132 from driving the lower pressure plate 134 to move rigidly downward when the aquatic plants are laid too thickly, resulting in large resistance between the collecting grid 3 and the lower pressure plate 134, affecting the reciprocating movement of the collecting grid 3.

[0054] like Figure 1 、 Figure 2 、 Figure 10 and Figure 11 As shown, as a preferred embodiment, on the basis of the above-mentioned manner, the transmission part further includes a connecting plate 12 fixedly mounted on the mounting plate 2, a transmission rod 121 rotatably connected to the connecting plate 12 and connected to the crankshaft 1001, a worm 122 disposed on the transmission rod 121, and a worm wheel 123 disposed on the rotating tube 4 and meshing with the worm 122, wherein the transmission rod 121 is coaxially arranged with the crankshaft 1001;

[0055] When the crank shaft 1001 rotates around the motor output shaft, it drives the transmission rod 121 to rotate. The worm 122 on the transmission rod 121 engages with the worm wheel 123 on the rotating tube 4 for transmission, so that the rotating tube 4 drives the cleaning component 5 to rotate to clean the aquatic plants in the water body. The coaxial transmission reduces the mechanical energy loss during power transmission, and the efficient engagement of the worm wheel 123 and the worm 122 effectively improves the overall transmission efficiency, so that the aquatic plant cleaning mechanism cooperates and is interrelated with the reciprocating movement of the collection grid 3 to achieve coordinated movement, making the aquatic plant cleaning and collection process more coherent and smooth. It should be noted that a shell should be provided at the engagement point of the worm wheel 123 and the worm 122 for protection according to the specific situation.

[0056] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
