Description

Technical Field

[0001] This utility model relates to the dredging mechanism of a river and canal dredging machine, and belongs to the technical field of waterway cleaning equipment. Background Technology

[0002] A canal dredging machine is a device used to clean silt from the inner walls of canals. Traditional mechanical dredging equipment often uses a single scraper or a fixed structure to remove silt. However, due to limitations in its structure and operation, its dredging method is relatively simple. For thick silt layers, it can often only clean the surface and cannot achieve thorough removal, resulting in poor dredging effect. On the other hand, the scraper movement of traditional equipment is mostly reciprocating, which cannot continuously and efficiently transport the scraped silt to the outside of the canal, resulting in low work efficiency. Utility Model Content

[0003] The purpose of this utility model is to provide a dredging mechanism for a river dredging machine, so as to improve the working efficiency of the river dredging machine.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A dredging mechanism for a river dredging machine includes several scrapers and a transmission component, wherein the scrapers rotate cyclically along the inner wall of the river ditch under the drive of the transmission component. It also includes a dredging frame; scrapers are fixed at fixed intervals on the transmission components; a drive wheel and a driven wheel are set on the dredging frame; the drive wheel and the driven wheel cooperate with the transmission components for transmission; the dredging frame has a shape consistent with the cross-section of the river channel, and the scrapers move along the outer contour of the dredging frame.

[0005] A further improvement to the technical solution of this utility model is that the transmission component is a chain; the driving wheel is a driving sprocket, and the driven wheel is a driven sprocket, both of which mesh with the chain.

[0006] A further improvement to the technical solution of this utility model is that: the driving sprocket and the driven sprocket are set at both ends of the upper part of the dredging frame 1; and mudguards are set on the dredging frame behind the scrapers on both sides and the lower part.

[0007] A further improvement to the technical solution of this utility model is that an auxiliary sprocket is set at the lower end of the dredging frame, and the chain meshes with the auxiliary sprocket.

[0008] A further improvement to the technical solution of this utility model is as follows: multiple sets of chains are arranged in parallel to each other, and multiple sets of driving sprockets and driven sprockets are arranged accordingly; the sprockets are arranged on the rotating shaft, and bearing seats are arranged at both ends of the rotating shaft; the bearing seats are installed at the ends of the dredging frame by adjusting screws.

[0009] A further improvement to the technical solution of this utility model is as follows: a sprocket mounting adjustment frame is fixedly installed at the end of the dredging frame; an adjustment screw is installed on the sprocket mounting adjustment frame and its position is adjusted by a nut; the lower end of the adjustment screw is connected to the bearing seat.

[0010] Due to the adoption of the above technical solution, the technical effects achieved by this utility model are as follows: This utility model discloses a dredging mechanism used by dredging machines to clean silt from the inner walls of waterways. The mechanism comprises multiple scrapers and a transmission component. The scrapers are fixed to the transmission component, and a dredging frame is used in conjunction to allow the transmission component to move the scrapers along the inner wall of the waterway, thus achieving the scraping of silt. Due to the multiple scrapers, this method enables highly efficient silt removal. The scrapers of the dredging mechanism rotate in a circular motion, pushing the scraped silt to the outside of the waterway, improving the silt removal effect.

[0011] This invention features a sprocket mounting adjustment bracket fixedly installed at the end of the dredging frame. An adjustment screw is mounted on the sprocket mounting adjustment bracket, and its position on the bracket is adjusted using a nut. Through the sprocket mounting adjustment bracket and the cooperation of the adjustment screw and nut, this design allows for fine-tuning of the scraper and chain, including adjusting the chain tension, to ensure the effective working condition of the scraper.

[0012] In this invention, multiple chains are arranged in parallel to each other, so that each scraper is fixedly connected to multiple chains at the same time, ensuring that the scraper is in a stable fixed installation state and that the scraper works stably when scraping silt.

Detailed Implementation

[0014] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0015] In the description of this utility model, it should be noted that the terms "upper", "lower", "inner", "outer", "front end", "rear end", "both ends", "one end", "the other end", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0016] This utility model relates to a dredging mechanism used in a canal dredging machine, specifically a mechanism for directly cleaning silt from the inner wall of a canal.

[0017] This dredging mechanism uses scrapers to remove silt from the inner wall of a canal. It mainly consists of several scrapers 2 and a transmission component, with the scrapers 2 fixedly mounted on the transmission component. A drive transmission mechanism works in conjunction with the transmission component, driving the scrapers 2 to scrape the silt along the inner wall of the canal. The scrapers 2 are plate-like structures, vertically fixed to the transmission component. Driven by the transmission component, the scrapers 2 rotate in a circular trajectory. The circular rotation path of the scrapers 2 roughly matches the cross-sectional shape of the canal, effectively scraping and cleaning the silt from the inner wall of the canal during the cyclical transmission process.

[0018] like Figure 1 , Figure 2 , Figure 3 As shown, the dredging mechanism also includes a dredging frame 1, on which the scraper 2 and transmission components are mounted. A drive wheel and a driven wheel are also provided. Both the drive wheel and the driven wheel cooperate with the transmission components to achieve transmission. The drive wheel provides the driving function, while the driven wheel provides the transmission function. Another function of the dredging frame 1 is to guide the cyclic rotation of the scraper 2 and the transmission components. The dredging frame 1 is roughly the same shape as the cross-section of the river channel. The transmission components can be considered as fitting around the outer periphery of the dredging frame 1. Thus, the transmission components move along the outer contour of the dredging frame 1, thereby enabling the transmission components to carry the scraper 2 along the outer contour of the dredging frame 1, and the scraper 2 to scrape away the silt from the inner wall of the river channel.

[0019] In specific implementation, the transmission component in the dredging mechanism is preferably a chain 4, with a driving sprocket 6 and a driven sprocket 7. The driving sprocket 6 serves as the main drive wheel, and the driven sprocket 7 serves as the driven wheel. The driving sprocket 6 and the driven sprocket 7 mesh with the chain to form a sprocket-chain transmission mechanism, thereby realizing the normal cyclic rotation transmission of the transmission mechanism. Multiple scrapers 2 are provided, and the scrapers 2 are fixedly installed perpendicular to the chain 4, with adjacent scrapers 2 spaced apart.

[0020] like Figure 1 , Figure 2As shown in the figure, the driving sprocket 6 and driven sprocket 7 of the dredging mechanism are typically located at both ends of the upper part of the dredging frame 1; the driving sprocket 6 and driven sprocket 7 are respectively located at both ends of the dredging frame 1. The chain 4 meshes with the driving sprocket 6 and driven sprocket 7, and the lower part of the chain 4 runs around the outer contour of the dredging frame 5. On the rear side of the dredging frame 1, specifically, mudguards 3 are installed on both sides of the dredging frame 1 and behind the lower scraper 2 to prevent the scraped silt from rolling backward, allowing the scraper 2 to push the silt to an area outside the canal. In addition, an auxiliary sprocket can be installed at the lower end of the dredging frame 1 to allow the chain 4 to transition smoothly. Roughly, the driving sprocket, driven sprocket, and auxiliary sprocket cause the chain to form a roughly triangular motion trajectory.

[0021] like Figure 1 , Figure 2 As shown, to ensure the effective and stable installation of the scraper 2, multiple sets of chains 4 are set for each dredging mechanism, with multiple chains 4 arranged in parallel. The scraper 2 is simultaneously fixedly connected to multiple chains 4, ensuring a stable and fixed installation. Correspondingly, multiple sets of driving sprockets 6 and driven sprockets 7 are also required when setting multiple sets of chains 4. Furthermore, multiple sprockets in the same position form a group, and this group of sprockets is mounted on a rotating shaft. Bearing seats 12 are set at both ends of the rotating shaft; bearings are located within the bearing seats 12, and the two ends of the rotating shaft are mounted within the bearing seats 12 via bearings, enabling smooth rotation. Driving sprockets of the same group are mounted on the same rotating shaft, as are driven sprockets and auxiliary sprockets of the same group. Furthermore, an adjusting screw 8 is provided, which is used to install the bearing seats 9. The adjusting screw 8 and bearing seats 9 are installed at both ends of the dredging frame 1.

[0022] like Figure 1 , Figure 2 As shown, a sprocket mounting adjustment bracket 5 is fixedly installed at the end of the dredging frame 1. The sprocket mounting adjustment bracket 5 can be installed at both ends of the dredging frame 1; alternatively, it can be installed at only one end of the dredging frame 1. When installed at one end, it is positioned at the end of the driven sprocket. An adjusting screw 8 is mounted on the sprocket mounting adjustment bracket 5, and a nut is attached to the adjusting screw 8. The position of the adjusting screw 8 on the sprocket mounting adjustment bracket 5 is adjusted using the nut. After adjustment, the adjusting screw 8 is fixed to the sprocket mounting adjustment bracket 5 using the nut. A bearing seat 9 is connected to the lower end of the adjusting screw 8, thus installing the bearing seat 9 and consequently the sprocket. Fine-tuning of the chain tension ensures the effective working condition of the scraper.

[0023] The dredging mechanism of this utility model adopts a structure in which a transmission component drives multiple scrapers, so that the multiple scrapers scrape off the silt by rotating in a circular manner along the inner wall of the water channel, which can improve the silt removal and cleaning effect.

[0024] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
