Abstract
Description
Technical Field
[0001] This utility model belongs to the field of dredging technology, specifically relating to a dredging robot bucket assembly. Background Technology
[0002] In sludge treatment, large particles clog the pump body, traditional single-layer filters cannot filter in stages, fibrous debris easily clogs the pump inlet, and existing buckets lack pre-crushing devices (such as piles of flexible materials like stones, plastic waste, and aquatic plants). Hard particles directly enter the pump body, causing the impeller to jam. Some existing systems use filters for blocking filtration, but due to the limited discharge area, the filters still cause equipment blockage. In addition, existing buckets have insufficient self-cleaning capabilities. When the sludge has low moisture content, it increases the difficulty and time required to crush the sludge. Furthermore, the lack of cleaning of the blade assembly makes the equipment unable to adapt to high-viscosity sludge, and cleaning mostly relies on periodic cleaning. Utility Model Content

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the present utility model and are not intended to limit the present utility model; that is, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The components of the embodiments of the present utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.
[0024] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
[0025] The following is combined Figure 1-4This invention describes a dredging robot bucket assembly, comprising a feed hopper 1, a rotating blade assembly 2 rotatably connected inside the feed hopper 1, a pump suction unit 3 connected to the feed hopper 1, and a spray unit 4 located on the bucket. Driven by the dredging machine, the bucket scoops up sludge. After scooping up the sludge, the rotating blade assembly 2 transports the sludge to the pump suction unit 3. The pump body 31 within the pump suction unit 3 extracts the sludge. During sludge removal, the spray unit 4 sprays water into the feed hopper 1 to increase the moisture content of the sludge and to initially break it up, facilitating the rotating blade assembly 2 to break up some of the lumpy sludge. After sludge removal, the spray unit 4 serves for self-cleaning of the rotating blade assembly 2. The feed hopper 1 has a discharge port connected to the pump suction unit 3. The discharge port 11 is fixedly equipped with a blocking member 12, which blocks the discharge port 11 and divides it into multiple feeding areas to prevent large pieces of sludge or stones from entering the discharge port 11 and causing blockage or damage to the pump suction component 3. The rotating blade assembly 2 includes a spiral blade 22 and a scraper 23 connected in the bucket. The scraper 23 faces the discharge port 11. The pump suction component 3 is used to suck the sludge out of the bucket. During sludge removal, some gauze or plastic bags are adsorbed onto the discharge port 11 and the blocking member 12 under negative pressure. Since the scraper 23 is aimed at the discharge port 11, it can cut and separate the obstruction through its own rotation to prevent blockage and damage to the pump suction component 3. The spray component 4 is used to spray fluid toward the rotating blade assembly 2 and the sludge.
[0026] Please refer to Figures 1-2 As shown, the rotary cutter assembly 2 also includes a spiral roller 21 rotatably connected to the feed hopper 1. The spiral blades 22 and the scraper 23 are fixedly connected to the spiral roller 21. A drive device 24 for driving the spiral roller 21 to rotate is provided on one side of the feed hopper 1. The spiral blades 22 realize the centralized conveying of sludge in the bucket to the discharge port 11 to improve the suction efficiency of the pump suction component 3. The drive device 24 is used to drive the spiral roller 21, as well as the spiral blades 22 and scraper 23 fixedly connected to the spiral roller 21 to rotate synchronously.
[0027] Please refer to Figure 2As shown, the spiral blade 22 includes a first spiral blade 221 and a second spiral blade 222. The first spiral blade 221 and the second spiral blade 222 are located on both sides of the scraper 23, and the spiral distribution directions of the first spiral blade 221 and the second spiral blade 222 are opposite. The discharge port 11 is located at the center of the feed hopper 1. Under the driving rotation of the spiral roller 21, the first spiral blade 221 and the second spiral blade 222 can realize the conveying of sludge in the feed hopper 1 to the discharge port 11 in the middle, thereby increasing the amount of sludge accumulated at the discharge port 11. On the one hand, it can... The scraper 23 at the discharge port 11 is used to cut and crush the accumulated sludge, reducing the diameter of the sludge when it passes through the discharge port 11, thus avoiding blockage and damage to the pump suction component 3. On the other hand, since the sludge accumulates at the discharge port 11, the pump suction efficiency of the pump suction component 3 is effectively improved, avoiding intermittent pump suction. It should be noted that when the sludge accumulated in the middle of the feed hopper 1 exceeds the processing capacity of the pump suction component 3, the excess sludge will flow out through the gap between the rotating cutter group 2 and the feed hopper 1. In addition, the total amount of sludge in the feed hopper 1 can be adjusted by controlling the moving speed of the bucket, thus avoiding the pump suction component 3 from working under load.
[0028] Please refer to Figure 3 As shown, the scraper 23 is located at the center of the spiral roller 21 along its length. The scraper 23 forms sharp blades 231 on both sides and at the ends away from the spiral roller 21, and a gap is formed between the edge of the sharp blade 231 at the end and the blocking member 12. The sharp blade 231 facilitates the cutting of mud, plastic parts, and yarn waste.
[0029] Please refer to Figure 4 As shown, the blocking member 12 is a grid bar, which is used to block the discharge port 11 to form multiple discharge zones. In some embodiments, the number of blocking members 12 can be set according to the diameter of the discharge port 11 and the pumping power of the pump suction member 3, dividing the discharge port 11 into multiple discharge zones to block large pieces of mud and garbage, preventing them from entering the pump suction member 3 and clogging or damaging the equipment. In this application, there are two grid bars, which divide the discharge port 11 into three discharge zones to block large pieces of material.
[0030] Please refer to Figures 1-3 As shown, the pump suction component 3 includes a suction pipe 32 connected to the discharge port 11. The suction pipe 32 is equipped with a pump body 31, which is used to provide negative pressure for suctioning sludge, so as to realize the suction of sludge through the discharge port 11. The end of the suction pipe 32 away from the feed hopper 1 can be connected to a conveying pipeline.
[0031] Please refer to Figure 4As shown, the spraying component 4 includes a spray pipe 41 rotatably connected to the feed hopper 1 and a spray head 42 connected to the spray pipe 41. The bucket 1 is provided with a drive component that can drive the spray pipe to rotate. By controlling the drive component to rotate the spray pipe 41 and the spray head 42 connected to the spray pipe 41 synchronously, the spray head 42 is directed towards the rotating cutter group 2 and the sludge spraying fluid at the optimal angle. On the one hand, it can moisten and initially crush the sludge blocks with low moisture content in the feed hopper 1, thereby reducing the time required for the rotating cutter group 2 to crush the sludge blocks. On the other hand, it can be used for the self-cleaning of the rotating cutter group 2 after sludge removal.
[0032] Please refer to Figure 4 As shown, multiple spray heads 42 are provided, and the multiple spray heads 42 are evenly distributed along the length direction of the spray pipe 41. The multiple spray heads 42 are distributed at equal intervals along the length of the spray pipe 41 to improve the spraying effect.
[0033] Working principle of this utility model:
[0034] The bucket is connected to the dredging machine and is driven by the dredging machine to move in the dredging pipeline. During the movement of the feed hopper 1, the sludge is removed. After removal, the sludge is transported from both ends of the feed hopper 1 to the middle of the feed hopper 1 under the rotation of the first spiral blade 221 and the second spiral blade 222, so that the sludge accumulates in the middle of the feed hopper 1. During the accumulation process, the scraper 23 can crush the mud and stones mixed in the sludge to reduce the particle size. The suction pipe 32 of the pump suction component 3 is connected to the discharge port 11, and the sludge accumulated in the feed hopper 1 is extracted under the action of the pump body 31.
[0035] When the sludge contains plastic parts and yarn-like waste that cannot be broken by the scraper 23, the waste blocks the discharge port 11 under the negative pressure formed by the pump body 31. Since the scraper 23 has sharp blades 231 on both sides and at the end, the sharp blades 231 can cut the blocked waste into pieces under the action of rotation, so that it can pass through the discharge port 11 and avoid blocking the discharge port 11 or the suction pipe 32.
[0036] During the sludge removal process, when the internal sludge blocks have low moisture content, the sludge blocks can be moistened by the spray head 42 to reduce the time required for the scraper 23 to break up the sludge blocks and improve the breaking effect. In addition, after the sludge removal is completed, the rotating blade assembly 2 can be cleaned by the spray head 42.
[0037] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0038] The above description is merely an example and illustration of the structure of this utility model. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the structure of the utility model or exceed the scope defined in the claims, they should all fall within the protection scope of this utility model.
