Description

Technical Field

[0001] The utility model relates to the technical field of drainage channel cleaning, in particular to a device for cleaning debris from a farmland water conservancy drainage channel. Background Art

[0002] Farmland water conservancy drainage channels are not only an important part of farmland water conservancy infrastructure, but also play an important role in maintaining the balance and ecological health of farmland ecosystems. Farmland water conservancy drainage channels often contain dead branches, weeds, branches, plastic bags and other debris cut around the channels. These debris are washed into the farmland irrigation outlet along with the accumulated water in the farmland water conservancy drainage channels, blocking the drainage outlet of the drainage channel. When it rains, the drainage cannot be drained normally, causing water accumulation in the drainage channel, flooding of surrounding vegetable fields, and inability to cultivate the fields, causing losses to farmers. Therefore, it is necessary to clean up the debris in the drainage channel regularly to avoid blockage of the drainage outlet.

[0003] After searching, the Chinese patent announcement number CN219118109U is disclosed, which discloses a debris cleaning device for a water conservancy drainage channel. The rake rod rotates under the action of a driving device and fishes out the debris in the water. At the same time, the rake rod passes through the give way groove, concentrates the debris on the screen plate, and continues the debris cleaning operation. Some of the debris in the water will flow with the water flow. Under the action of the filter plate, the debris is restricted on its surface. As the rake rod rotates and passes through the active cavity, the debris is cleaned in turn and turned over to the collection mechanism for centralized treatment, thereby preventing the debris from flowing away with the water flow and improving the debris cleaning effect. When the rake rod rotates to an inclined upward state, the debris on its surface will slide along the inclination amplitude of the rake rod. Due to the provision of a curved portion, the debris will fall on the surface of the curved portion. As the rake rod continues to advance during rotation, the debris is pushed to the surface of the screen plate, thereby preventing the cleaned debris from falling into the water again. Subsequently, the debris slides along the inclination amplitude of the screen plate into the collection groove.

[0004] Although the above patent has a drainage hole at the bottom of the collecting tank, there is still a lot of water between the debris, which makes the whole device heavier and increases the difficulty of moving. Utility Model Content

[0024] The present utility model will be further described below in conjunction with the accompanying drawings:

[0025] Such as Figures 1 - 5As shown in the figure, a device for cleaning sundries in a farmland water conservancy drainage canal includes a water canal 1. A temporary storage box 2 is arranged at the top of the water canal 1. A number of water drainage holes are opened at the bottom of the temporary storage box 2. A walking wheel 201 is arranged at the bottom of the temporary storage box 2. The walking wheel 201 is driven by a servo motor bolted to the bottom of the temporary storage box 2. The temporary storage box 2 moves on the water canal 1 through the walking wheel 201. A number of grid teeth 202 are fixedly connected to the top of the temporary storage box 2. The grid teeth 202 are inclined, which is convenient for the scraped sundries to gradually slide into the temporary storage box 2 under the action of the inclined plane.

[0026] A cleaning mechanism is arranged on one side of the temporary storage box 2 close to the grid teeth 202. The cleaning mechanism includes two mounting frames 301 bolted to one side of the temporary storage box 2. The two mounting frames 301 are arranged front and back. A rotary motor 302 is bolted to the front side of the front mounting frame 301. The output end of the rotary motor 302 is connected to a mounting shaft 303 through a coupling. The mounting shaft 303 is rotatably connected between the two mounting frames 301. A number of rake rods 304 arranged circumferentially are fixedly connected to the mounting shaft 303. The rake rods 304 are arranged in a staggered manner with the grid teeth 202. When the rotary motor 302 is started, the rotary motor 302 drives the mounting shaft 303 to drive the rake rods 304 to rotate. The waterweeds or other sundries on the water surface are filtered onto the rake rods 304. When the rake rods 304 rotate to the position where they cross the grid teeth 202, the grid teeth 202 scrape off the sundries between the rake rods 304.

[0027] An extrusion mechanism is arranged in the temporary storage box 2. The extrusion mechanism includes a sliding plate 404 and an extrusion plate 405 slidably connected in the temporary storage box 2. A spring 406 is connected between the sliding plate 404 and the extrusion plate 405. The extrusion plate 405 is located behind the sliding plate 404. A pressure sensor 407 is fixedly connected to the rear side of the sliding plate 404. The magnitude of the extrusion force is controlled through the pressure sensor 407. When the pressure sensor 407 reaches the set value, it indicates that the extrusion is in place.

[0028] The extrusion mechanism further includes a power component for driving the sliding plate 404 to move. The power component includes a stepping motor 401 bolted to the front side of the temporary storage box 2. The output end of the stepping motor 401 is connected to a lead screw 402 through a coupling. The lead screw 402 is rotatably connected between the front and rear inner walls of the temporary storage box 2. A slide bar 403 is also fixedly connected between the front and rear inner walls of the temporary storage box 2. The sliding plate 404 is threadedly connected to the lead screw 402. The sliding plate 404 is slidably connected to the slide bar 403. The lead screw 402 is located on the side of the temporary storage box 2 away from the grid teeth 202. When the stepping motor 401 is started, the stepping motor 401 drives the lead screw 402 to rotate, and the lead screw 402 drives the sliding plate 404 to move backward along the slide bar 403, pushing the sundries in the temporary storage box 2 backward.

[0029] A discharge opening is provided at the rear side of the temporary storage box 2, and a plugging assembly is arranged in the discharge opening. The plugging assembly includes a cross plate 501 bolted to the rear side of the temporary storage box 2. A hydraulic cylinder 502 is fixedly connected to the top of the cross plate 501. A lifting frame 503 is fixedly connected to the top of the hydraulic cylinder 502. A baffle 504 is fixedly connected to the bottom of the lifting frame 503. The baffle 504 is slidably connected in the discharge opening. By controlling the hydraulic cylinder 502, the lifting frame 503 drives the baffle 504 to move up and down to determine the opening and closing of the discharge opening. An inclined extension plate 6 is bolted to the rear side of the temporary storage box 2. The extension plate 6 is located above the traveling wheel 201 and below the discharge opening. The traveling wheel 201 is protected by the extension plate 6 to prevent sundries from winding around the traveling wheel 201 and affecting the normal running of the traveling wheel 201. The extension plate 6 is inclined to facilitate the sliding of the sundries falling on the extension plate 6.

[0030] Working principle: During use, the temporary storage box 2 moves along the water channel 1 through the traveling wheels 201. The rotary motor 302 is started, and the rotary motor 302 drives the mounting shaft 303 to drive the rake rod 304 to rotate. The waterweeds or other sundries on the water surface are filtered onto the rake rod 304. When the rake rod 304 rotates to a position where it intersects with the grate teeth 202, the grate teeth 202 scrape off the sundries between the rake rods 304. The grate teeth 202 are inclined, so that the scraped-off sundries gradually slide into the temporary storage box 2 under the action of the inclined plane. The stepper motor 401 is started, and the stepper motor 401 drives the lead screw 402 to rotate. The lead screw 402 drives the sliding plate 404 to move backward along the slide bar 403 to push the sundries in the temporary storage box 2 backward. When the sundries abut against the baffle 504, the sundries are restricted by the baffle 504. At this time, the sliding plate 404 continues to move backward, and the extrusion force continuously increases to squeeze out the water between the sundries. When the pressure sensor 407 reaches the set value, the hydraulic cylinder 502 is controlled to make the lifting frame 503 drive the baffle 504 to move upward to open the discharge opening, and the spring 406 is released to push the sundries to one side of the water channel 1, thereby reducing the overall weight of the cleaning device and facilitating movement.
