Description

Technical Field

[0001] The invention relates to the technical field of drainage ditch sediment cleaning, in particular to drainage ditch sediment cleaning equipment. Background Art

[0002] The drainage ditch sediment cleaning equipment is a mechanical equipment used to clean the sediment, garbage and other impurities in the drainage ditch to keep the drainage unobstructed. During the layout of the project construction site, in order to ensure the smooth drainage in the construction site, it is necessary to reasonably set up drainage ditches in the site to avoid water accumulation caused by rainwater or other water sources. Due to the large number of transport vehicles traveling, a large amount of sediment and dust will be deposited in the drainage ditch on site, causing the drainage ditch to be blocked and the drainage in the site to be poor. In the prior art, a bucket is usually installed at the front end of a forklift, and the bucket is driven by the forklift to move in the drainage ditch to clean the drainage ditch. At the same time, the forklift can control the bucket to lift and dump, which is convenient for cleaning the silt and impurities in the bucket; When the forklift controls the bucket to rise, the water at both ends of the bucket will flow to the bottom of the bucket, and the silt impurities usually have a certain fluidity in the water, and may flow with the water to the ditch section that has been cleaned under the bucket. When the bucket is lowered again for cleaning, the silt impurities accumulate under the bucket, which may cause the bucket to be unable to descend to the bottom of the drainage ditch. When cleaning again, the bucket cannot effectively clean the silt impurities at the bottom of the drainage ditch, resulting in a decrease in the cleaning effect of the bucket. Silt impurities are still likely to remain in the drainage ditch. For this reason, we propose a drainage ditch silt cleaning equipment. Summary of the invention

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention limits the limit bar through the card slot, so that the roller shaft cannot rotate when the cylinder descends. When the telescopic bottom plate enters the drainage ditch, the limit bar enters the movable groove from the card slot, and at the same time, the two gears will mesh with the first rack, and the two gears will drive the roller shaft to rotate counterclockwise. The roller shaft will drive the lifting rod, the lifting bar and the lifting frame to move downward while rotating counterclockwise, so that the telescopic bottom plate moves downward while its front end rotates downward. When the front end of the telescopic bottom plate contacts the bottom of the drainage ditch, the gear will no longer mesh with the first rack, but will mesh with the second rack, so that the roller shaft will move clockwise, the rear end of the telescopic bottom plate will move downward, and at the same time, its front end will rotate upward and move forward along the bottom of the drainage ditch, so as to scrape off the silt and impurities that flow toward the cleaned ditch section with the water flow during the rising process of the telescopic bottom plate; 2. The present invention uses the cylinder to drive the lifting bar to rise. After the telescopic bottom plate leaves the drainage ditch, the guide rods will move to the top of the guide groove. As the cylinder continues to rise, the lifting rods will slide in the slide groove, and one of the guide rods will rotate forward at the top of the corresponding guide groove, while the other guide rod will continue to move upward along the arc groove, so that the lifting bar drives the two lifting frames and the telescopic bottom plate to deflect and tilt. The slide bar will no longer pull the elastic rope, and the elastic force of the torsion spring will drive the reel to reel up the elastic rope and drive the rotating shaft to rotate, so that the second side plate is deflected and keeps the same angle with the telescopic bottom plate. At this time, the lifting frame drives the telescopic bottom plate to keep the tilted state, so that the silt impurities on the telescopic bottom plate can flow downward under gravity; 3. The present invention utilizes the sliding bar to move downward under the action of gravity when the lifting frame is tilted, so that the spring is further compressed and the limit on the wedge bar is released. The wedge bar will drive the first magnetic block and the second magnetic block to move downward in the lifting frame under the action of gravity. The first magnetic block will no longer be aligned with the magnetic beads to provide magnetic attraction. The second magnetic block will be aligned with the magnetic beads and provide magnetic repulsion thrust, so that the magnetic beads drive the sliding rod and the scraper to slide along the limiting groove. The scraper can scrape off the silt impurities on the telescopic bottom plate, and at this time the telescopic bottom plate and the second side plate are both in an inclined state, which is convenient for the scraped silt impurities to flow away.

A telescopic bottom plate 26 is arranged between the first side plate 27 and the second side plate 29. The rotating rod 19 can drive the screw rods 20 at both ends to rotate synchronously. Through the cooperation between the screw rods 20 and the limiting holes 22, and the limiting of the lifting frame 21 by the lifting bar 14, the two lifting frames 21 can be made to move relative to each other or move in the opposite direction synchronously. The two lifting frames 21 will respectively drive the first side plate 27 and the second side plate 29 to move, so that the width of the telescopic bottom plate 26 can be adjusted, and drainage ditches of different widths can be used. Two filters 25 are arranged between the two lifting frames 21. One end of the two filters 25 is fixedly mounted on the two lifting frames 21 respectively. When the two lifting frames 21 are adjusted, the corresponding filters 25 will be driven to move respectively. Both filters 25 will perform filtering, so that the filtering width is always matched with the width of the telescopic bottom plate 26.

[0019] Limiting strips 6 are fixedly installed at both ends of the roller shaft 5, and slots 8 for limiting the limiting strips 6 are arranged on the inner walls on both sides of the lifting seat 3. A movable slot 9 for releasing the limiting strips 6 is connected below each slot 8. A gear 7 is fixedly installed at one end of the two limiting strips 6. Two lifting slots 12 for limiting the gear 7 are arranged in the lifting seat 3. A first rack 10 and a second rack 11 meshing with the gear 7 are fixedly installed on the inner walls on both sides of each lifting slot 12, and the second rack 11 is located below the first rack 10. When the cylinder 4 drives the roller shaft 5 to descend, the limiting strips 6 are limited by the slots 8. The roller shaft 5 will be unable to rotate, and the lifting frame 21 and the telescopic bottom plate 26 will keep descending horizontally. When the telescopic bottom plate 26 enters the drainage ditch, the limiting strip 6 will enter the movable groove 9 from the card slot 8, and the limiting strip 6 will no longer be limited by the card slot 8. At the same time, the two gears 7 will mesh with the first rack 10. As the cylinder 4 drives the roller shaft 5 to descend, the two gears 7 will drive the roller shaft 5 to rotate counterclockwise, and the roller shaft 5 will drive the lifting rod 13, the lifting strip 14 and the lifting frame 21 to move downward while rotating counterclockwise, so that the telescopic bottom plate 26 moves downward and its front end rotates downward. When the front end of the telescopic bottom plate 26 contacts When the cylinder 4 reaches the bottom of the drainage ditch, the gear 7 will no longer mesh with the first rack 10, but will mesh with the second rack 11. As the cylinder 4 continues to retract, the gear 7 will drive the roller 5 to move clockwise, the rear end of the telescopic bottom plate 26 will move downward, and at the same time, its front end will rotate upward and move forward along the bottom of the drainage ditch to scrape off the silt and impurities that flow toward the cleaned ditch section during the rise of the telescopic bottom plate 26. After the cylinder 4 has retracted, the roller 5 will drive the lifting frame 21 and the telescopic bottom plate 26 back to a horizontal state. When the cylinder 4 drives the roller 5 to rise, the gear 7 will mesh with the second rack 11 first, so that the roller 5 will move first. The telescopic bottom plate 26 is driven to move counterclockwise, and the rear end of the telescopic bottom plate 26 will rise with the roller shaft 5 of the cylinder 4, and its front end will retreat along the bottom of the drainage ditch to prevent the water from suddenly rushing to the lower end of the telescopic bottom plate 26 and bringing a large amount of silt. When the roller shaft 5 moves upward to make the gear 7 mesh with the first rack 10, the roller shaft 5 will drive the telescopic bottom plate 26 to move clockwise, and the front end of the telescopic bottom plate 26 will gradually return to the horizontal to prevent the silt from sliding from its front end into the drainage ditch. When the gear 7 ends the meshing with the first rack 10 upward, the limit bar 6 will move upward again into the slot 8 to prevent the roller shaft 5 from driving the telescopic bottom plate 26 to deflect.

[0020] Guide rods 16 are fixedly installed at both ends of the lifting bar 14. Two guide grooves 17 for limiting the guide rods 16 are arranged on the lifting seat 3. An arc groove 18 is connected to the upper end of one of the guide grooves 17. A slide groove 15 for limiting the lifting rod 13 is arranged in the lifting bar 14. When the cylinder 4 drives the roller shaft 5, the lifting rod 13 and the lifting bar 14 to descend, the guide rods 16 at both ends of the lifting bar 14 are located in the corresponding guide grooves 17, so that the lifting bar 14 keeps descending horizontally. When the cylinder 4 drives the lifting bar 14 to rise, after the telescopic bottom plate 26 leaves the drainage ditch, the guide rods 16 will move to the top of the guide groove 17. As the cylinder 4 continues to rise, the lifting rod 13 is lowered. 3 will slide in the chute 15, one of the guide rods 16 will rotate forward at the top of the corresponding guide groove 17, and the other guide rod 16 will continue to move upward along the arc groove 18, so that the lifting bar 14 drives the two lifting frames 21 and the telescopic bottom plate 26 to deflect and tilt, which is convenient for the subsequent cleaning of silt and impurities on the telescopic bottom plate 26. When the cylinder 4 drives the lifting bar 14 to descend, one of the guide rods 16 will rotate in the opposite direction at the top of the corresponding guide groove 17 to reset, and the other guide rod 16 will move downward along the arc groove 18 to reset, so that the lifting bar 14 drives the lifting frames 21 and the telescopic bottom plate 26 to restore to a horizontal state, and the lifting rod 13 will also reset in the chute 15.

[0021] A first telescopic sleeve 23 and a second telescopic sleeve 24 are fixedly connected between the two lifting frames 21. A magnetic bead 33 is slidably installed in the first telescopic sleeve 23. A slide bar 32 is fixedly installed on the magnetic bead 33. A limiting groove 34 for limiting the slide bar 32 is provided on the first telescopic sleeve 23. A scraper 30 for cleaning the silt on the surface of the telescopic bottom plate 26 is fixedly installed at the lower end of the slide bar 32 through a plurality of telescopic rods 31. The lower end of the scraper 30 is set in a wedge shape, and the telescopic joint of the telescopic bottom plate 26 is also set in a wedge shape. A first magnetic block 35 that is magnetically attracted to the magnetic bead 33 is slidably installed in one of the lifting frames 21. A second magnetic block 35 that is magnetically repelled from the magnetic bead 33 is fixedly installed on the upper end of the first magnetic block 35. Magnetic block 36, a wedge-shaped bar 37 is fixedly installed at the lower end of the first magnetic block 35, a slide bar 38 matching the wedge-shaped bar 37 is slidably installed inside the second telescopic sleeve 24, and a spring 39 is fixedly connected between the slide bar 38 and the inner wall of the second telescopic sleeve 24, and the spring 39 is always in a compressed state. The gravity of the slide bar 38 is greater than the elastic force of the spring 39. When the cylinder 4 drives the lifting frame 21 to descend, the second telescopic sleeve 24 will always remain in a horizontal state. The elastic force of the spring 39 will push one end of the slide bar 38 to contact the inclined surface of the wedge-shaped bar 37, so that the wedge-shaped bar 37 drives the first magnetic block 35 and the second magnetic block 36 to move upward, and the magnetic attraction of the first magnetic block 35 to the magnetic bead 33 keeps the slide bar 32 always in a limited position. At the initial end of the groove 34, the scraper 30 will be close to the first side plate 27. When the cylinder 4 drives the lifting frame 21 to rise, after the lifting frame 21 is tilted, since the gravity of the slide bar 38 is greater than the elastic force of the spring 39, the slide bar 38 will move downward under the action of gravity, so that the spring 39 is further compressed and the limit of the wedge bar 37 is released. The wedge bar 37 will drive the first magnetic block 35 and the second magnetic block 36 to move downward in the lifting frame 21 under the action of gravity. The first magnetic block 35 will no longer align with the magnetic bead 33 to provide magnetic attraction. The second magnetic block 36 will align with the magnetic bead 33 and provide a magnetic repulsive thrust, so that the magnetic bead 33 drives the slide bar 32 and the scraper 30 to slide along the limit groove 34, and the scraper 30 can The silt and impurities on the telescopic bottom plate 26 are scraped off, and when the scraper 30 encounters the joint of the telescopic bottom plate 26, the thrust of the telescopic rod 31 makes the lower end of the scraper 30 always close to the surface of the telescopic bottom plate 26, thereby improving the cleaning effect. When the cylinder 4 descends and drives the lifting frame 21 to restore to a horizontal state, the elastic force of the spring 39 will push the slide bar 38 to reset, and the wedge bar 37 will drive the first magnetic block 35 and the second magnetic block 36 to move upward again. The first magnetic block 35 will be aligned with the magnetic bead 33 again, and the magnetic attraction therebetween will reset the scraper 30 to be close to the first side plate 27, and the telescopic joint between the lower end of the scraper 30 and the telescopic bottom plate 26 is set to be wedge-shaped, thereby reducing the resistance of the scraper 30 when it retracts.

[0022] A rotating shaft 28 is fixedly installed at one end of the telescopic bottom plate 26, and the second side plate 29 is fixedly installed on the rotating shaft 28. A reel 40 is fixedly installed at one end of the rotating shaft 28. A torsion spring 42 is fixedly connected between the reel 40 and the inner wall of the lifting frame 21, and an elastic rope 41 is fixedly connected between the reel 40 and the slide bar 38. The elastic force of the spring 39 is greater than the elastic force of the torsion spring 42. A baffle 43 for limiting the second side plate 29 is fixedly installed on one of the lifting frames 21. During the descending process of the lifting frame 21, since the elastic force of the spring 39 is greater than the elastic force of the torsion spring 42, the elastic rope 41 will be straightened, and according to the distance between the two lifting frames 21 being stretched to a certain length, the torsion spring 42 will also rotate to store force, and the second side plate 29 is limited by the baffle 43. The lifting frame 21 will maintain a vertical state. When the lifting frame 21 rises and tilts, the slide bar 38 will no longer pull the elastic rope 41. The elastic force of the torsion spring 42 will drive the reel 40 to reel in the elastic rope 41, and drive the rotating shaft 28 to rotate, so that the second side plate 29 is deflected and maintains the same angle with the telescopic bottom plate 26. At this time, the lifting frame 21 drives the telescopic bottom plate 26 to maintain a tilted state, so that the silt impurities on the telescopic bottom plate 26 can flow downward due to gravity, and the scraper 30 can scrape them off, further improving the cleaning effect of the telescopic bottom plate 26. When the lifting frame 21 descends again and returns to a horizontal state, the slide bar 38 will pull the elastic rope 41 again, so that the torsion spring 42 drives the reel 40 and the rotating shaft 28 to rotate, so that the second side plate 29 returns to a vertical state again.

[0023] Specifically, firstly, the rotating rod 19 is rotated to drive the screw rods 20 at both ends thereof to rotate synchronously. Through the cooperation between the screw rod 20 and the limiting hole 22, and the limiting of the lifting frame 21 by the lifting bar 14, the two lifting frames 21 are made to move relative to each other or move in the opposite direction synchronously. The two lifting frames 21 will respectively drive the first side plate 27 and the second side plate 29 to move, so that the width of the telescopic bottom plate 26 can be adjusted, and drainage ditches of different widths can be used. Then, the cylinder 4 drives the roller shaft 5 to descend. Through the limiting of the limiting strip 6 by the card slot 8, the roller shaft 5 will not be able to rotate, and the lifting frame 21 and the telescopic bottom plate 26 will keep descending horizontally. When the telescopic bottom plate 26 enters the drainage ditch, the limiting strip 6 will enter the movable groove 9 from the card slot 8, and the limiting strip 6 will no longer be limited by the card slot 8. At the same time, the two gears 7 will The roller shaft 5 is meshed with the first rack 10. As the cylinder 4 drives the roller shaft 5 to descend, the two gears 7 will drive the roller shaft 5 to rotate counterclockwise. The roller shaft 5 will drive the lifting rod 13, the lifting bar 14 and the lifting frame 21 to move downward and rotate counterclockwise, so that the telescopic bottom plate 26 moves downward while its front end rotates downward. When the front end of the telescopic bottom plate 26 contacts the bottom of the gutter, the gear 7 will no longer mesh with the first rack 10, but will mesh with the second rack 11. As the cylinder 4 continues to retract, the gear 7 will drive the roller shaft 5 to move clockwise, and the rear end of the telescopic bottom plate 26 will move downward, while its front end will rotate upward and move forward along the bottom of the gutter, scraping off the silt and impurities that flow toward the cleaned ditch section with the water flow during the rising process of the telescopic bottom plate 26. After the cylinder 4 has been retracted, the roller shaft 5 will drive the lifting frame 21 and the telescopic bottom plate 26 back to the horizontal state. When the cylinder 4 drives the roller shaft 5, the lifting rod 13 and the lifting bar 14 to descend, the guide rods 16 at both ends of the lifting bar 14 are located in the corresponding guide grooves 17, so that the lifting bar 14 keeps descending horizontally. When the cylinder 4 drives the lifting frame 21 to descend, the second telescopic sleeve 24 will always remain in the horizontal state, and the elastic force of the spring 39 will push one end of the slide bar 38 to contact the inclined surface of the wedge bar 37, so that the wedge bar 37 drives the first magnetic block 35 and the second magnetic block 36 to move upward. Through the magnetic attraction of the first magnetic block 35 to the magnetic bead 33, the slide bar 32 is always at the initial end of the limit groove 34, and the scraper 30 will be close to the first side plate 27. During the descent of the lifting frame 21, due to The elastic force of the spring 39 is greater than the elastic force of the torsion spring 42, the elastic rope 41 will be straightened, and according to the distance between the two lifting frames 21, it will be stretched to a certain length, and the torsion spring 42 will also rotate to store force, and the second side plate 29 will be limited by the baffle 43, and the second side plate 29 will remain in a vertical state. After the cylinder 4 is completely lowered, the worker drives the power-assisted vehicle 1 to drive the equipment to move forward along the drainage ditch, and the silt and impurities enter the top of the telescopic bottom plate 26 and are filtered by the filter screen 25, so that the water flows out and the silt and impurities accumulate on the telescopic bottom plate 26, and then the cylinder 4 is controlled to rise. When the cylinder 4 drives the roller shaft 5 to rise, the gear 7 will mesh with the second rack 11 first, so that the roller shaft 5 will first drive the telescopic bottom plate 26 to move counterclockwise, and the rear end of the telescopic bottom plate 26 will rise with the cylinder 4 roller shaft 5.Its front end will retreat along the bottom of the drainage ditch to prevent the water from suddenly rushing to the lower end of the telescopic bottom plate 26 and bringing a large amount of silt. When the roller 5 moves upward to make the gear 7 mesh with the first rack 10, the roller 5 will drive the telescopic bottom plate 26 to move clockwise, and the front end of the telescopic bottom plate 26 will gradually return to the horizontal state to prevent the silt from sliding from its front end into the drainage ditch. When the gear 7 ends the meshing with the first rack 10 upward, the limit bar 6 will move upward again into the card slot 8 to prevent the roller 5 from driving the telescopic bottom plate 26 to deflect. When the cylinder 4 drives the lifting bar 14 to rise, the telescopic bottom plate 26 leaves the drainage ditch, and the guide The rods 16 will move to the top of the guide groove 17. As the cylinder 4 continues to rise, the lifting rod 13 will slide in the slide groove 15. One of the guide rods 16 will rotate forward at the top of the corresponding guide groove 17, and the other guide rod 16 will continue to move upward along the arc groove 18, so that the lifting bar 14 drives the two lifting frames 21 and the telescopic bottom plate 26 to deflect and tilt, which is convenient for subsequent cleaning of silt and impurities on the telescopic bottom plate 26. When the cylinder 4 drives the lifting frame 21 to rise, after the lifting frame 21 tilts, the gravity of the slide bar 38 is greater than the elastic force of the spring 39, and the slide bar 38 will be affected by gravity. The spring 39 is further compressed by the downward movement, and the limit of the wedge strip 37 is released. The wedge strip 37 is acted upon by gravity and drives the first magnetic block 35 and the second magnetic block 36 to move downward in the lifting frame 21. The first magnetic block 35 is no longer aligned with the magnetic bead 33 to provide magnetic attraction. The second magnetic block 36 is aligned with the magnetic bead 33 and provides a thrust of magnetic repulsion, so that the magnetic bead 33 drives the slide bar 32 and the scraper 30 to slide along the limit groove 34. The scraper 30 can scrape the silt and impurities on the telescopic bottom plate 26. When the scraper 30 encounters the joint of the telescopic bottom plate 26, the thrust of the telescopic rod 31 causes the scraper 32 to move downward. The lower end of the plate 30 is always in close contact with the surface of the telescopic bottom plate 26, which improves the cleaning effect. When the lifting frame 21 rises and tilts, the slide bar 38 will no longer pull the elastic rope 41, and the elastic force of the torsion spring 42 will drive the reel 40 to reel the elastic rope 41, and drive the rotating shaft 28 to rotate, so that the second side plate 29 is deflected and keeps the same angle with the telescopic bottom plate 26. At this time, the lifting frame 21 drives the telescopic bottom plate 26 to maintain an inclined state, so that the silt impurities on the telescopic bottom plate 26 can flow downward due to gravity, and the scraper 30 can scrape them off, further improving the cleaning effect of the telescopic bottom plate 26.
