Description

Technical Field

[0001] The utility model relates to the technical field of aquatic weed salvaging, in particular to a device for collecting and salvaging aquatic weeds for river regulation. Background Art

[0002] Managing and removing aquatic weeds is crucial in river management. Current aquatic weed collection and salvaging devices often face a technical challenge: weeds tend to become entangled in the collection rollers. This problem not only reduces salvage efficiency but also easily damages the device, increasing maintenance and component replacement costs.

[0003] Existing aquatic weed salvaging equipment typically includes a weed cutting device and a weed collecting device. The weed cutting device, located at the front end of the equipment, is used to cut the weeds, while the weed collecting device, located adjacent to the cutting device, is used to transport the cut weeds to a designated location. However, in practice, the weeds are easily entangled around the collecting roller during collection. This not only hinders smooth weed transportation but can also cause mechanical failure due to excessive entanglement. In severe cases, the machine may even need to be shut down for cleaning, significantly affecting work efficiency.

[0004] Chinese patent announcement number CN219003263U discloses a waterweed cleaning device for river management. By setting up a conveyor belt, the waterweed can be broken by a cutting mechanism, and then the waterweed is salvaged and transported to a feed port by a conveying component. At the same time, a motor drives a stirring column to rotate to break the waterweed through a cutting blade, and then the waterweed residue is sprayed out of the hull by a slag spraying component. This solves the problem in the prior art of generally using a salvage ship to break the bottom of the waterweed to make the waterweed float up, and then transporting the waterweed to the ship by a conveyor belt. During the transportation on the conveyor belt, the waterweed is easy to fall from both sides, and the pipeline is easy to be blocked when the waterweed is broken and discharged, thereby reducing the salvage efficiency. It has the advantages of avoiding blockage of the discharge pipe and preventing the waterweed from falling.

[0005] However, in actual use of the above structure, the aquatic plants will be entangled on the drum when they are broken and reeled in. This entanglement phenomenon will not only reduce the salvage efficiency, but also force the operator to frequently stop the machine due to excessive entanglement to manually clean the aquatic plants on the drum, thereby interrupting the continuous operation process.

[0028] In order to further understand the features, technical means, specific objectives and functions achieved by the present invention, the present invention is described in further detail below in conjunction with the accompanying drawings and specific implementation methods.

[0029] See also Figure 1-Figure 3As shown, a river channel management water grass collection and salvage device includes a hull 1, a cockpit 11 arranged on the hull 1, a first conveyor belt 2 installed on the hull 1 and used to transport water grass, a first rotary driver 3 installed on the hull 1 and used to drive the first conveyor belt 2 to transport, and a cutting anti-winding mechanism 4 arranged on the hull 1 and used to prevent water grass from being entangled. The cutting anti-winding mechanism 4 includes a docking setting plate 41, a plurality of collecting rotating pieces 42 arranged on the docking setting plate 41 for collecting and salvaging water grass, and a plurality of cutting pieces 43 arranged on the docking setting plate 41 and used to cut water grass wound on the collecting rotating pieces 42. The river channel management water grass collection and salvage device also includes a plurality of cutting pieces 43 arranged on the docking setting plate 41 and used to drive the collecting rotating pieces 42 to rotate forward and drive the cutting pieces 43 to rotate forward. 43 is a transmission drive mechanism 5 that rotates in the opposite direction. Several avoidance grooves for water to pass through are provided on the first conveyor belt 2. Several toggle rods 431 are provided in a circumferential array on the cutting blade 43 to toggle the water plants entangled after cutting. A blocking piece 432 is provided on the docking setting plate 41 to prevent the water plants from being thrown out of the outside of the first conveyor belt 2 by the cutting blade 43 and the toggle rod 431 after cutting. A clamping roller is provided on the hull 1 to limit the stable transportation of the first conveyor belt 2. The clamping roller is located below the first conveyor belt 2. The collecting rotating piece 42 and the cutting piece 43 are spaced apart from each other and have several. A driven roller 31 is provided on the first rotary driver 3. The first conveyor belt 2 is composed of a first conveying rotating roller 51 and a second conveying rotating roller. The driven roller 31 is provided with a transfer belt 32 connected to the second conveying rotating roller.

[0030] When it is necessary to cut the water grass, the first rotary driver 3 is started first, and the transfer belt 32 provided on the driven roller 31 can drive the second conveying rotary roller and the first conveying rotary roller 51 to rotate, thereby driving the first conveyor belt 2 to convey. During this process, the first rotary driver 3 can drive the collecting rotary sheet 42 to rotate forward through the transmission driving mechanism 5, thereby winding the water grass around the collecting rotary sheet 42, and at the same time, the cutting sheet 43 rotates in the opposite direction. When the cutting sheet 43 rotates in the opposite direction, the water grass wound on the collecting rotary sheet 42 can be cut. The cut water grass can be toggled by the toggle lever 431 provided on the cutting sheet 43 and blocked by the blocking sheet 432 until the water grass is thrown onto the first conveyor belt 2 by the cutting sheet 43 and the toggle lever 431 after cutting, thereby achieving the purpose of quickly collecting the wound water grass and throwing it out after cutting, avoiding the water grass from being wrapped and attached to the collecting rotary sheet 42 all the time, and cutting the collected water grass to reduce the volume of the water grass, which is convenient for subsequent processing.

[0031] See also Figure 2-Figure 4As shown, the transmission drive mechanism 5 includes a first conveying rotary roller 51, a first rotating roller 52 and a first transmission belt 53; the first conveying rotary roller 51 is set on the docking setting plate 41, and the first conveying rotary roller 51 is used to support the first conveyor belt 2 for rotating feeding movement; the first rotating roller 52 is rotatably set on the docking setting plate 41 and is coaxially fixed with the collecting rotating sheet 42; the first transmission belt 53 is respectively sleeved on the first conveying rotary roller 51 and the first rotating roller 52.

[0032] When it is necessary to cut the aquatic plants, the first rotary driver 3 is started first, which drives the first conveyor belt 2 to rotate. During the rotation of the first conveyor belt 2, the first conveyor rotating roller 51 can be driven to rotate. When the first conveyor rotating roller 51 rotates, the first rotating roller 52 can be driven to rotate through the first transmission belt 53. When the first rotating roller 52 rotates, it can drive several coaxially fixed cutting blades 43 to wrap around and collect the aquatic plants.

[0033] See also Figure 4-Figure 6 As shown, the transmission drive mechanism 5 also includes a bearing rotating rod 54, a supporting rod 55, a main gear 56, a driven gear 57 and a second transmission belt 58; the bearing rotating rod 54 is rotatably set on the docking setting plate 41 and is located above the first rotating roller 52; the supporting rod 55 is rotatably set on the docking setting plate 41 and is coaxially fixed with the cutting blade 43; the main gear 56 is set on the bearing rotating rod 54 and coaxially fixed with the bearing rotating rod 54; the driven gear 57 is set on the supporting rod 55 and coaxially fixed with the supporting rod 55, and the driven gear 57 is engaged with the main gear 56; the second transmission belt 58 is respectively sleeved on the first rotating roller 52 and the bearing rotating rod 54.

[0034] When the first rotating roller 52 rotates, the bearing rotating rod 54 can be driven to rotate through the first transmission belt 53. When the bearing rotating rod 54 rotates, it can drive the main gear 56 fixed coaxially therewith to rotate. When the main gear 56 rotates, it can rotate the meshed driven gear 57 and the supporting rod 55 in the opposite direction. When the supporting rod 55 rotates, it can drive several cutting blades 43 and the toggle rod 431 fixed coaxially therewith to rotate, so that the waterweed wrapped around the cutting blade 43 can be cut and toggled for collection, thereby avoiding the attachment of waterweed on the cutting blade 43.

[0035] See also Figure 6 and Figure 7 As shown, the transmission drive mechanism 5 also includes a rotating laminating roller 59 and a third transmission belt 591; the rotating laminating roller 59 is rotatably set on the docking setting plate 41 and is located above the first conveyor belt 2; the third transmission belt 591 is respectively mounted on the supporting rod 55 and the rotating laminating roller 59.

[0036] When the supporting rod 55 rotates, the third transmission belt 591 can drive the rotating crushing roller 59 to crush and cut the aquatic plants thrown onto the first conveyor belt 2 for the second time, which helps to reduce the volume of the aquatic plants after cutting and facilitates the subsequent processing of the aquatic plants.

[0037] See also Figure 8 and Figure 9 As shown, the river management aquatic weed collection and salvage device also includes an extrusion mechanism 6 arranged on the hull 1 for extruding the cut and crushed aquatic weeds into shape; the extrusion mechanism 6 includes a first linear drive 61, a bidirectional screw 62 and an extrusion block 63; the first linear drive 61 is arranged on the hull 1; the input end of the bidirectional screw 62 is arranged at the output end of the first linear drive 61 through a coupling; the extrusion block 63 is slidably arranged on the hull 1 in a horizontal linear direction and is threadedly engaged with the bidirectional screw 62, and a processing tank for processing the cut aquatic weeds is opened on the hull 1.

[0038] The water grass after the second cutting can fall into the processing tank, and then the first linear drive 61 is started, and drives the bidirectional screw 62 to rotate. During the rotation of the bidirectional screw 62, it can drive the extrusion block 63 to extrude the water grass that falls into the processing tank after cutting, so as to facilitate the rapid extrusion molding of the cut water grass, squeeze out the moisture in the water grass, and facilitate the effective processing of the extruded water grass.

[0039] See also Figure 8 and Figure 9 As shown, the extrusion mechanism 6 also includes a guide block 64, a displacement block 65, an ejection block 66 and a hinged rod 67; the guide block 64 is symmetrically arranged on the hull 1 and has a pair; the displacement block 65 is slidably arranged between the pair of guide blocks 64 in the horizontal straight direction, and the displacement block 65 and the guide block 64 are clearance-fitted; the hinged rod 67 has a pair and is rotatably arranged on the extrusion block 63 and the displacement block 65 respectively.

[0040] During the relatively approaching movement of the extrusion block 63, the displacement block 65 can be driven by the hinged rod 67 to slide along the guide block 64 in a horizontal straight line direction until the displacement block 65 and the ejection block 66 are away from one side of the extrusion block 63. After the extrusion block 63 is extruded and moves relatively away, the displacement block 65 and the ejection block 66 can be pulled out by the hinged rod 67 until the ejection block 66 pushes out the extruded water plants, thereby achieving automatic ejection of the extruded water plants without the need for manual handling.

[0041] See also Figure 4-Figure 9 As shown, the extrusion mechanism 6 also includes a discharge trough 68 and a second conveying mechanism 69; the discharge trough 68 is opened on the hull 1, and the discharge trough 68 is used to discharge the extruded water plants; the second conveying mechanism 69 is arranged on the discharge trough 68, and the second conveying mechanism 69 is used to convey the extruded water plants.

[0042] When the squeezed waterweed is pushed by the pushing block 66, it can fall onto the second conveying mechanism 69, and then the second conveying mechanism 69 can be started to discharge the squeezed waterweed without manual unloading.

[0043] Working principle: When it is necessary to cut the waterweed, the first rotary driver 3 is started first, and the second conveying rotary roller and the first conveying rotary roller 51 can be driven to rotate by the transfer belt 32 set on the driven roller 31, and then the first conveyor belt 2 can be driven to convey. During this process, the first conveying rotary roller 51 drives the first rotating roller 52 to rotate through the first transmission belt 53, and drives the fixed cutting blade 43 to wind and preliminarily collect the waterweed. At this time, the first transmission belt 53 also drives the bearing rotating rod 54 and the coaxial main gear 56 to rotate. The main gear 56 is engaged with the driven gear 57, driving the supporting rod 55 and the cutting blade 43 fixed thereon and the toggle rod 431 to rotate in the opposite direction, realizing the cutting and toggling collection of the waterweed to prevent the waterweed from adhering. When the supporting rod 55 rotates, it is driven to rotate through the third transmission belt 591 The crushing roller 59 crushes and cuts the waterweed on the conveyor belt for the second time to reduce the volume of the waterweed. The cut waterweed falls into the processing tank, and then the first linear drive 61 is started to drive the bidirectional screw 62 to rotate, and then the extrusion block 63 is driven to squeeze the waterweed, quickly squeeze out the water, and facilitate subsequent processing. The waterweed after the second cutting falls into the processing tank, and then the first linear drive 61 is started to drive the bidirectional screw 62 to rotate. The bidirectional screw 62 drives the extrusion block 63 to squeeze the waterweed in the processing tank, quickly squeeze out the water and shape it. In the process of the extrusion block 63 approaching, the displacement block 65 is pushed by the articulated rod 67 to slide horizontally along the guide rail block 64. When the extrusion is completed, the extrusion block 63 moves away, and the articulated rod 67 pulls the displacement block 65 and the connected push-out block 66 to extend, and the extruded waterweed is automatically pushed out without manual handling.

It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
