Description

Technical Field

[0001] This utility model belongs to the field of water conservancy facility maintenance technology, specifically relating to a rural ecological ditch cleaning device. Background Technology

[0002] Ecological ditches, also known as nitrogen and phosphorus interception ditches, are ecological engineering projects that utilize the physical, chemical, and biological mechanisms within wetland ecosystems to intercept, retain, absorb, and transform nutrients such as nitrogen and phosphorus in water bodies. They not only serve as drainage channels for farmland runoff but also effectively reduce the levels of pollutants such as chemical oxygen demand (COD), total nitrogen, and total phosphorus in farmland discharge water, thus purifying the effluent. The dredging of ecological ditches is of great significance: by removing silt and debris, water flow is maintained, preventing silt accumulation and ensuring unobstructed waterways; dredging helps reduce the accumulation of harmful substances in the water, improving the water body's self-purification capacity and protecting the health of the aquatic ecosystem; plants and microorganisms in the ecological ditches can absorb and transform nutrients in the water, and dredging helps maintain the balance of this ecosystem, preventing eutrophication; dredged ecological ditches are clearer and more transparent, harmonizing with the surrounding natural environment and enhancing the landscape effect.

[0003] Ecological ditches not only contain sludge but also aquatic plants that grow alongside it. When these aquatic plants are excessive, they can obstruct water flow, affecting the ecological balance and the ditch's flowability. Existing dredging equipment is often easily entangled and blocked by aquatic plants during operation, thus reducing dredging effectiveness. Utility Model Content

[0025] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the preferred embodiments of this utility model will be described in detail below to facilitate understanding by those skilled in the art.

[0026] Please see Figures 1 to 8 This utility model provides a rural ecological ditch cleaning device, comprising: a fixed bracket 2 mounted on an engineering vehicle 1; an electric rotary table 3 mounted on the fixed bracket 2; a horizontal telescopic mechanism 4 mounted on the electric rotary table 3; a vertical telescopic mechanism 6 mounted on a first movable rod 5 of the horizontal telescopic mechanism 4; a screw-type sludge pump 8 mounted on a second movable rod 7 of the vertical telescopic mechanism 6; a cleaning hopper 9 connected to the inlet of the screw-type sludge pump 8; a cutting mechanism mounted on the cleaning hopper 9; and a sludge filter box 10 mounted on the engineering vehicle 1. The outlet of the screw-type sludge pump 8 is provided with a conveying pipe 11 connected to the sludge filter box 10. In this embodiment, the engineering vehicle carries an onboard generator and a power distribution box, which supplies power to the electric rotary table 3, the horizontal telescopic mechanism 4, the vertical telescopic mechanism 6, and the screw-type sludge pump 8 to ensure their normal operation.

[0027] The horizontal telescopic mechanism 4 includes: a first base 42 disposed on the rotary table surface of the electric rotary table 3; a first movable rod 5 slidably disposed on the first base 42; and a first servo motor 12 driving the first movable rod 5 to move horizontally.

The first servo motor 12 drives the first reducer 16, the first reducer 16 drives the first gear 17, and the first gear 17 drives the first movable rod 5 to slide within the first through groove 14. The first servo motor 12 is a self-locking servo motor. By controlling the electric rotary table 3 and the second servo motor 19, the horizontal telescopic mechanism 4 can be extended and retracted on both sides of the engineering vehicle 1. It can also allow the cleaning bucket 9 to be suspended at the rear of the engineering vehicle 1, making it convenient for the engineering vehicle 1 to reach the work site.

[0028] The telescopic mechanism 6 includes: a second base 18 mounted on the first movable rod 5; a second movable rod 7 slidably mounted on the second base 18; and a second servo motor 19 driving the second movable rod 7 to move up and down.

[0029] The front end of the cleaning hopper 9 is open, and the rear end of the cleaning hopper 9 is connected to the inlet. The cutting mechanism is located at the front end opening. Driven by the engineering vehicle 1, the front end opening of the cleaning hopper 9 moves forward towards the sludge and aquatic plants.

The transmission of the first belt 30 allows the first rotating shaft 24 and the second rotating shaft 27 to rotate in the same direction, while the first blades 25 and the second blades 28 move in opposite directions at their intersection, effectively cutting aquatic plants and preventing the first rotating shaft 24 and the second rotating shaft 27 from becoming entangled, as well as preventing the screw sludge pump 8 from becoming entangled. It also dilutes the sludge, making it easier for the screw sludge pump 8 to suck it up. The severing mechanism also includes a waterproof cover covering the first pulley 26, the second pulley 29, the third pulley 31, the fourth pulley 34, the first belt 30, the second belt 35, and the third servo motor 32.

[0033] When using the rural ecological ditch cleaning device of this utility model:

[0034] The engineering vehicle 1 is driven to the work position and brought close to the ecological ditch. The electric rotary table 3 is controlled by the PLC controller to turn the cleaning bucket to one side of the ecological ditch. The cleaning bucket is brought to the top of the ecological ditch by the horizontal telescopic mechanism 4. The cleaning bucket is lowered to the bottom of the ecological ditch by the vertical telescopic mechanism 6. After starting the screw sludge pump 8, the engineering vehicle 1 drives the cleaning bucket to clean the ecological ditch by moving forward or backward. The first valve 39 or the second valve 41 on the side close to the ecological ditch is opened to allow the water to flow back into the ecological ditch.

[0035] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and not to limit it.
