Description
Technical Field
[0001] The utility model relates to the technical field of water conservancy projects, and in particular to a drainage channel desilting device. Background Art
[0002] Drainage channels, also known as "drains", are engineering facilities used to direct water from one place to another. Drainage channels are an important engineering facility that plays a vital role in farmland irrigation, urban drainage and water conservancy projects. Through reasonable design and construction, drainage channels can effectively collect and remove excess water and maintain environmental balance and safety.
[0003] As an important part of urban infrastructure, drainage canals are responsible for removing sewage and rainwater.

With the development of science and technology, although some mechanized dredging equipment has emerged, there are still deficiencies in dealing with solid silt and complex terrain, and mechanical dredging equipment is complex and costly. Therefore, it is necessary to study an efficient and easy-to-operate drainage canal dredging device. Utility Model Content

DETAILED DESCRIPTION
[0027] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0028] Example:
[0029] like Figures 1 to 6 As shown, a drainage channel desilting device includes a chassis 7, and crawler wheels 2 are installed on both the front and rear sides of the chassis 7. A base 1 is fixed on the chassis 7. Two sets of lifting hanging rods 15 are symmetrically arranged inside the base 1. The lower ends of the lifting hanging rods 15 are fixedly connected to the bucket 4 through the frame 11. A hydraulic cylinder 16 is installed on the right side of the bottom of the base 1. The output end of the hydraulic cylinder 16 is fixedly connected to the top of the two sets of lifting hanging rods 15 through a connecting bracket 17 with a triangular structure. A sludge pump 8 is installed on the left side of the upper end surface of the base 1. A sewage pipe 9 is fixedly connected to the output end of the sludge pump 8. A sewage cover 12 is installed on the lower side of the left end surface of the bucket 4. The input end of the sludge pump 8 is connected to the sewage cover 12 through the suction pipe 10, and the front and rear end surfaces of the bucket 4 are provided with scraping components 14 near the left edge. A water spray component 3 is provided on the right side of the base 1. The front and rear sides of the bucket 4 are equipped with spiral blades 5. The left end of the spiral blade 5 extends out of the bucket 4 and is fixedly connected to the output end of the drive motor 13. This design solves the problem that the existing dredging method mainly relies on manual cleaning, which is not only time-consuming and labor-intensive, but also inefficient and has safety hazards. In addition, the existing mechanical dredging equipment still has shortcomings when dealing with solid silt and complex terrain, and the equipment is complex and the cost is high.
[0030] In this embodiment, the two sets of spiral blades 5 rotate in opposite directions, the left spiral blade 5 rotates clockwise, and the right spiral blade 5 rotates counterclockwise. When the two sets of spiral blades 5 rotate relative to each other, an intertwined stirring effect is generated, which can stir and crush the sludge, making it easier to be excavated. At the same time, the rotation of the two sets of spiral blades 5 can drive the sludge to move toward the bucket 4, and the sludge is transported to the bucket 4, which is helpful for the suction and discharge of the sludge, speeds up the cleaning speed of the sludge, and improves the dredging efficiency.
[0031] In this embodiment, the chassis 7 is composed of a fixing frame 71, a support shaft 72, an adjusting screw 73 and a cross plate 74. The fixing frame 71 is arranged between two groups of crawler wheels 2. Both ends of the fixing frame 71 are fixedly connected to the crawler wheels 2 through the support shaft 72, and the support shaft 72 is inserted inside the fixing frame 71. Two adjacent groups of support shafts 72 are fixedly connected through the cross plate 74. The inside of the cross plate 74 is screwed with an adjusting screw 73, and the end of the adjusting screw 73 is rotatably connected to the fixing frame 71. The fixing frame 71 and the support shaft 72 form an integral frame, which provides a stable foundation for the device and ensures the stability of the device. At the same time, by rotating the adjusting screw 73, the support shaft 72 can be driven to telescopically move inside the fixing frame 71 to adjust the spacing between the two groups of crawler wheels 2, thereby realizing the width adjustment of the chassis 7, which is convenient for adapting to drainage channels of different widths and improves the adaptability and scope of use of the device.
[0032] In this embodiment, the water spray assembly 3 includes a water tank 31, a support plate 32, a water pump 33, a water inlet pipe 34, a water delivery pipe 35 and a nozzle 36. The support plate 32 is fixedly arranged at the right end of the base 1, and a water tank 31 is fixedly arranged on the support plate 32 to provide sufficient water for the water spraying operation. A water pump 33 is assembled on the front side of the bottom of the support plate 32, and a nozzle 36 is arranged on the right side of the bottom of the support plate 32, and the nozzle 36 is inclined to the lower right. The input end of the water pump 33 is connected to the water tank 31 through the water inlet pipe 34, and the output end of the water pump 33 is connected to the nozzle 36 through the water delivery pipe 35. The support plate 32 provides a stable support platform for the water tank 31, the water pump 33 and the nozzle 36. The water tank 31 is used to store water. The water pump 33 is responsible for pumping water out of the water tank 31 and transporting it to the nozzle 36 through the water pipe 35. The water can be sprayed into the drainage channel through the nozzle 36, which can moisten the silt, reduce its viscosity and consistency, facilitate cleaning and discharge, and improve dredging efficiency. At the same time, the nozzle 36 can spray high-pressure water to effectively flush and clean the silt on the spiral blade 5, reduce silt adhesion, and ensure the normal operation of the spiral blade 5.
[0033] In this embodiment, the scraping assembly 14 includes a scraper 141, a support rod 142, a fixed sleeve 143 and a reset spring 144. Two groups of fixed sleeves 143 are provided and are fixedly arranged on the left end surface of the bucket 4 near the edge. The two groups of fixed sleeves 143 are both inserted with support rods 142. The scraper 141 is fixedly connected to the right side of the support rod 142 ring surface. The fixed sleeve 143 is equipped with a reset spring 144, and the reset spring 144 is located at the bottom of the support rod 142. The scraping assembly 14 can clean the silt adhered to the inner wall of the drainage channel and scrape off the adhered silt, thereby improving the dredging effect of the drainage channel. The reset spring 144 and the support rod 142 provided at the same time enable the scraper 141 to be telescopically moved, so as to adapt to drainage channels of different widths.
[0034] In this embodiment, a T-shaped railing 6 is welded on the right end face of the bucket 4. The railing 6 can form a physical protection at the opening of the bucket 4, and can filter the silt, and filter out aquatic plants and solid garbage mixed in the silt to prevent them from entering the bucket 4 and causing blockage.
[0035] In this embodiment, a sliding sleeve 18 is fixedly provided at the connection between the base 1 and the lifting rod 15. The sliding sleeve 18 can reduce the friction of the lifting rod 15 during the lifting process, so as to reduce the wear of the lifting rod 15 during the lifting process and extend the service life of the equipment. At the same time, it can ensure that the lifting rod 15 slides smoothly in the vertical direction, maintains a stable motion trajectory, and reduces shaking and deviation.
[0036] The working principle of the drainage channel desilting device is as follows: in actual use, the device is first placed in the drainage channel, and the crawler wheel 2 is placed at the edge of the drainage channel. As needed, the width of the chassis 7 can be changed by adjusting the adjusting screw 73 to adapt to drainage channels of different widths. The hydraulic cylinder 16 pushes the two sets of lifting and hanging rods 15 up and down through the triangular structure connecting bracket 17, and the lifting and hanging rods 15 drive the bucket 4 to move up and down to adapt to the desilting needs of different depths. The crawler wheel 2 drives the device to move along the drainage channel. During this process, the two sets of spiral blades 5 inside the bucket 4 rotate in opposite directions to stir and crush the sludge, making it easier to be excavated and discharged. The stirred sludge is pushed toward the bucket 4 by the spiral blades 5, which is convenient for subsequent suction and discharge. At the same time, the scrapers 141 on both sides of the bucket 4 will scrape off the adhered sludge when they contact the inner wall of the drainage channel. The sludge pump 8 extracts the sludge from the sewage cover 12 at the left end of the bucket 4 through the suction pipe 10. The extracted sludge is discharged from the device through the sewage pipe 9. While the sludge is being transported, the water pump 33 is started, and the water pump 33 draws water from the water tank 31 and transports it to the nozzle 36 through the water pipe 35. The nozzle 36 sprays water into the drainage channel to wet the sludge, reduce its viscosity and consistency, and facilitate cleaning. At the same time, the high-pressure water flow of the nozzle 36 flushes the sludge on the spiral blade 5 to keep it clean. The T-shaped structural railing 6 at the right end of the bucket 4 filters the sludge entering the bucket 4 to prevent clogging by aquatic plants and solid garbage.
[0037] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the protection scope of the present invention.
