[0020] Please see Figure 1 This application provides a dredging device (100) for a drainage ditch in a jackfruit orchard, including a mobile chassis (10), a digging mechanism (20), a conveying mechanism (30), a crushing mechanism (40), and a blower mechanism (50). The mobile chassis (10) is used to move within the drainage ditch. The digging mechanism (20) is located at the front end of the mobile chassis (10) and is used to dig out silt and debris in the drainage ditch. The digging mechanism (20) includes a digging bucket (21) mounted on the mobile chassis (10) via a frame, a rotary paddle (22) located inside the bucket, a lifting drive (23) for driving the bucket to lift, and a swing drive (24) for driving the bucket to swing horizontally. The rotary paddle (22) includes a horizontally arranged rotating shaft (221) and multiple scrapers (222) fixed to its surface. The ends of the scrapers (222) are inclined in a counterclockwise direction. The rear end of the digging bucket (21) is provided with a discharge port (211). The conveying mechanism (30) is connected to the excavating mechanism (20) and is used to convey the excavated debris to the crushing mechanism (40). The conveying mechanism (30) and the discharge port (211) are connected by a flexible transition plate (25). The crushing mechanism (40) is used to crush the conveyed debris. The air blowing mechanism (50) is located at the bottom of the crushing mechanism (40) and is used to blow out the crushed debris.

[0021] The dredging device (100) provided in this application integrates excavation, conveying, crushing and blowing functions, which can efficiently remove silt and debris in drainage ditches, greatly reduce the intensity of manual labor and improve dredging efficiency. At the same time, it can crush the cleaned fallen leaves and other debris and blow them to the park as fertilizer, realize resource reuse, and benefit the park's ecological cycle and crop growth.

[0022] The mobile chassis (10) is used to move flexibly within the drainage ditch. It has multiple adjustable support wheels at its bottom to adapt to different terrains. The excavating mechanism (20) is located at the front end of the mobile chassis (10) and is used to excavate silt and debris within the drainage ditch. A conveyor connects to the excavating mechanism (20) and transports the excavated debris to the crushing mechanism (40) for crushing. A pneumatic blowing mechanism (50) is located at the bottom of the crushing mechanism (40) and is used to blow out the crushed debris, which is easily decomposed. Through the above structural design, continuous operation of drainage ditch dredging is achieved, which not only improves dredging efficiency but also reduces manual labor and labor intensity. In addition, the dredging device (100) is also equipped with a control system.

[0023] The excavation mechanism (20) is mounted on a mobile chassis (10) via a frame. The excavation mechanism (20) includes an excavation bucket (21), a rotary paddle (22), a lifting drive (23), and a swing drive (24). The upper end of the excavation bucket (21) is rotatably mounted on the frame via a horizontal bar (26). The frame is provided with a sliding groove for the two ends of the horizontal bar (26) to slide up and down, so as to adjust the excavation depth. In other words, the two ends of the horizontal bar (26) move up and down through a grooved rail structure. The rotary paddle (22) is installed inside the bucket and is used to transport the excavated debris from the front of the bucket to the rear, thereby improving the excavation efficiency. Specifically, the rotary paddle (22) includes a rotating shaft (221) and scrapers (222). The rotating shaft (221) is horizontally rotatably mounted inside the excavation bucket (21). Multiple scrapers (222) are evenly spaced and fixed on the surface of the rotating shaft (221). When the rotating shaft (221) rotates clockwise, it transports the excavated silt backward. Furthermore, the end of the scraper (222) is tilted counterclockwise to reduce the amount of debris remaining between the scrapers (222). The rear end of the excavator bucket (21) is provided with a discharge port (211), through which debris is discharged and flows to the conveying mechanism (30).

[0024] The excavating bucket (21) is installed at the lower end of the horizontal bar (26). The excavating bucket is equipped with multiple rows of detachable and replaceable digging teeth to adapt to silt of different hardness. The digging teeth can be fixed by screws or snap-fit. The lifting drive (23) is installed above the excavating bucket (21). The output shaft of the lifting drive (23) is connected to the horizontal bar (26) to drive the excavating bucket (21) to rise and fall to adjust the digging depth. The lifting drive (23) can be implemented in the form of a hydraulic cylinder, a pneumatic cylinder, or an electric push rod.

[0025] A swing drive (24) is installed on the rear side of the digging bucket (21). One end of the swing drive (24) is hinged to the frame, and the other end is hinged to the rear end of the digging bucket (21). By driving the swing drive (24) to extend and retract, the digging bucket (21) can swing left and right in the horizontal plane to adjust the angle of the digging bucket (21), thereby expanding the digging range and adapting to siltation areas of different widths and shapes in the drainage ditch. In a preferred embodiment of this application, the swing drive is a hydraulic cylinder.

[0026] A flexible transition plate (25) is directly connected to the discharge port (211) to prevent leakage of debris during the swinging of the excavator bucket (21). The flexible transition plate (25) is made of rubber with a certain degree of flexibility and wear resistance. It is installed at the connection between the discharge port (211) and the conveying mechanism (30). As the excavator bucket (21) swings, the flexible transition plate (25) can deform accordingly, thereby maintaining a sealed connection between the discharge port (211) and the conveying mechanism (30) and effectively preventing leakage of debris during the conveying process. At the same time, the surface of the flexible transition plate (25) is provided with anti-slip texture to increase the smoothness of debris flow and improve conveying efficiency.

[0027] The lower end of the conveying mechanism (30) is connected to the outlet (211) of the excavating mechanism (20), and the higher end extends above the feed inlet of the crushing mechanism (40). The conveying mechanism (30) includes an inclined conveyor belt (31) and a conveying base box (32) for carrying the conveyor belt (31). The conveying base box (32) is used to collect water left by the debris, and it has a drain outlet (321) at its lower end. The conveying mechanism (30) also includes a drive motor to drive the conveyor belt (31) to circulate, so as to efficiently transport the excavated debris to the crushing mechanism (40). Furthermore, the lower end of the conveying mechanism (30) is provided with a drain outlet (321) so as to drain the water in the sludge during the conveying process and reduce the burden of subsequent processing.

[0028] The crushing mechanism (40) includes a crushing box (41) and two rotating cutter shafts (42) disposed therein. Multiple crushing blades (43) are spaced apart on the rotating cutter shafts (42). The blades (43) on the two cutter shafts mesh with each other, and the high-speed rotation cuts and crushes the incoming debris. The crushed debris is discharged from the outlet at the bottom of the crushing box (41). In another embodiment, the crushing mechanism (40) uses a hammer mill or a shredder to accommodate different types of debris processing needs.

[0029] The air blowing mechanism (50) includes a blower and an air duct (not shown). The blower is installed on one side of the crushing box (41), and an exhaust port with an external exhaust duct is provided on the other side of the crushing box (41). The blower blows the crushed debris out of the crushing box (41) through the exhaust duct, allowing it to quickly leave the crushing area. At the same time, by controlling the wind force, the conveying distance and range of the debris can be adjusted to ensure that the debris can be efficiently and evenly conveyed to the designated location after crushing. Meanwhile, the debris is relatively dispersed, which facilitates rapid degradation by microorganisms. In use, the crushed debris is usually blown towards the roots of the fruit trees, so that the debris is evenly distributed around the root system of the fruit trees. This can both cover and retain moisture, and also replenish the soil with organic matter, thereby improving soil fertility. In addition, there is a regulating valve at the outlet of the air duct, which can adjust the air volume and blowing angle according to actual needs to adapt to different terrains and planting densities, ensuring accurate delivery of debris. The entire system has a compact structure and complete functions, realizing the integrated operation of digging, conveying, crushing and blowing, which greatly improves the efficiency of dredging drainage ditches and handling debris.

Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of this application, the scope of which is defined by the claims and their equivalents.
