Description

Technical Field

[0001] The utility model relates to a river cleaning device for engineering construction, belonging to the technical field of water conservancy projects. Background Technique

[0002] River silt accumulation and overgrown weeds are very common problems. This is because in the long-term flowing of river water, it continuously absorbs the sediment on the banks, thus forming a silt layer on the river bed. These silts are very conducive to the growth and reproduction of underwater plants. The problems such as river silt accumulation will seriously affect the normal functions of flood control, drainage, irrigation, water supply, etc. To restore the normal functions of the river, it is necessary to carry out dredging projects. If manual cleaning of river garbage and waterweeds is adopted, the efficiency is low, the construction period is long, the cost is high, it is time-consuming and laborious, and there are safety risks.

[0003] Moreover, when the existing river cleaning devices are in operation, most of them are provided with cutting teeth for crushing waterweeds. After several cutting teeth crush the waterweeds, the efficiency of the river cleaning device for salvaging them can be improved. After the cutting teeth are used for a long time and come into contact with different types of garbage and sundries, some cutting teeth will be worn. When some cutting teeth are severely worn and damaged and need to be replaced, however, in the existing cleaning equipment, the cutting teeth are mostly integrally fixed on the river cleaning device, and only several moving cutting blades in the same group can be replaced simultaneously. The replacement cost is relatively high, and the undamaged cutting teeth cannot be reused. Content of the Utility Model

[0004] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a river cleaning device for engineering construction.

[0011] Further, a through hole matching with the dial rod is formed on the surface of the mobile cutting blade. A rubber pad is arranged on the inner wall of the through hole. The rubber pad is pressed together with the dial rod.

[0012] The beneficial effects of the utility model:

[0013] By arranging the hydraulic cylinder, the operation of the hydraulic cylinder can adjust the inclination angles of the mounting frame, the support frame and the crawler, so that one end of the crawler is located under the water surface of the river channel, and thus it is convenient to fish the waterweeds on the water surface.

[0014] By setting up the mobile cutting mechanism, when cleaning the algae in the river channel, the motor can be started.

[0015] By setting up the installation mechanism, when the mobile cutting blades have been used for a long time and the wear seriously affects their use, the corresponding installation mechanism can be driven to release the clamping of the severely worn mobile cutting blades. Subsequently, brand-new mobile cutting blades can be replaced. In this way, when the mobile cutting blades are severely worn, the severely worn corresponding mobile cutting blades can be replaced, and there is no need to replace the entire set of cutting parts.

[0016] By setting up the positioning component, before inserting the end of the mobile cutting blade into the installation slot, it is necessary to press the four toggle rods to drive the four clamping blocks to move into the mobile cutting blade. Subsequently, insert the end of the mobile cutting blade into the installation slot. At this time, release the toggle rods. Under the action of the spring, the clamping blocks are driven to extend out of the sliding slot and snap into the clamping slots. At this time, the position of the mobile cutting blade is preliminarily positioned. Description of the Drawings

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0027] Please refer to Figures 1-7 The present utility model provides a technical solution for a river cleaning device for engineering construction. A river cleaning device for engineering construction includes a device body 1. An operation room 2 is provided at the top of the device body 1. A mounting frame 3 is rotatably connected to the top of the device body 1 and on the side of the operation room 2. A hydraulic cylinder 4 is connected between the middle parts of the device body 1 and the mounting frame 3. A crawler belt 29 is provided at the bottom end of the mounting frame 3. A support frame 5 is provided at the front top of the mounting frame 3. A group of fixed cutting blades 12 are respectively fixed on both sides of the front end of the support frame 5. A group of moving cutting mechanisms are respectively provided on both sides of the front end of the support frame 5 and at the front bottom of the support frame 5. By providing the hydraulic cylinder 4, the operation of the hydraulic cylinder 4 can adjust the inclination angles of the mounting frame 3, the support frame 5 and the crawler belt 29, so that one end of the crawler belt 29 is located under the water surface of the river, and thus it is convenient to fish up the waterweeds on the water surface.

[0028] Refer to Figure 1 And Figure 2, the mobile cutting mechanism includes a motor base 6 fixed on the support frame 5. A motor is fixed inside the motor base 6. The output end of the motor penetrates outside the motor base 6 and is connected to a rotating plate 7. One side of the surface of the rotating plate 7 is movably connected to a connecting rod 8. The other end of the connecting rod 8 is provided with a support plate 9. The sides of the support plates 9 on the left and right are respectively slidably connected to the inner walls on both sides of the support frame 5. The side of the bottom support plate 9 is provided with a moving block 28. The moving block 28 is slidably connected to the side of the support frame 5. The motor bases 6 on the three mobile cutting mechanisms are respectively fixed on the top sides and the bottom side of the support frame 5. A plurality of installation grooves 11 are formed on the surface of the support plate 9. Mobile cutting blades 10 are installed in the installation grooves 11. The end of the mobile cutting blade 10 penetrates outside the support plate 9. A positioning component matching with the installation groove 11 is arranged in the middle of the mobile cutting blade 10. A groove 19 is formed at the end of the mobile cutting blade 10 located inside the installation groove 11. An installation mechanism matching with the groove 19 is arranged in the installation groove 11. Through the setting of the mobile cutting mechanism, when cleaning the algae in the river, the motor can be started. The operation of the motor drives the rotating plate 7 to rotate. The rotation of the rotating plate 7 drives the connecting rod 8 to move. The movement of the connecting rod 8 drives the support plate 9 to move. The support plates 9 on the left and right will move up and down along with the mobile cutting mechanisms on the left and right. The mobile cutting mechanism at the bottom will drive the support plate 9 at the bottom to move left and right. Thus, large pieces of algae can be cut. As the device moves, the mobile cutting blades 10 will fish up the algae on the water surface for cutting and crushing. Subsequently, the crushed algae will be transported to the algae tank at the rear side of the device body 1 through the crawler 29.

[0029] Refer to Figure 3 and Figure 4 , the installation mechanism includes a motor rotating in the installation groove 11. The output end of the motor is connected to a driving gear 13. One driving gear 13 is meshed with a rack plate 14 on each of the upper and lower sides. Opposite ends of the two rack plates 14 are respectively provided with a plug 15. A guiding block 16 is arranged on the side of the rack plate 14. A guiding groove 17 matching with the guiding block 16 is formed on the inner wall of the installation groove 11. A slot 18 is formed on each of the two inner walls of the groove 19. The end of the plug 15 penetrates into the slot 18. Through the setting of the installation mechanism, when the mobile cutting blade 10 has been used for a long time and is severely worn and affects the use, the corresponding installation mechanism can be driven to release the clamping of the severely worn mobile cutting blade 10. Subsequently, a brand-new mobile cutting blade 10 can be replaced. In this way, when the mobile cutting blade 10 is severely worn, the severely worn corresponding mobile cutting blade 10 can be replaced, and there is no need to replace the entire set of cutting parts.

[0030] Refer toFigure 5 , Figure 6 and Figure 7 , the positioning component includes a sliding groove 20 formed in the middle of the movable cutting blade 10. Four clamping blocks 21 are symmetrically and slidably connected in the sliding groove 20. A clamping groove 27 matching with the clamping block 21 is formed on the inner wall of the installation groove 11. One slider 22 is provided on each side of the clamping block 21. One chute 23 matching with the slider 22 is formed on each inner wall of the two sides of the sliding groove 20. Two springs 24 are connected between the clamping block 21 and the sliding groove 20. A moving rod 25 is provided at the end of the clamping block 21 located in the sliding groove 20. A lever 26 is provided at one end of the moving rod 25. Through the setting of the positioning component, before inserting the end of the movable cutting blade 10 into the installation groove 11, it is necessary to press the four levers 26 to drive the four clamping blocks 21 to move into the movable cutting blade 10. Subsequently, the end of the movable cutting blade 10 is inserted into the installation groove 11. At this time, release the lever 26. Under the action of the spring 24, drive the clamping block 21 to extend out of the sliding groove 20 and snap into the clamping groove 27. At this time, the position of the movable cutting blade 10 is initially positioned.

[0031] Refer to Figure 1 , Figure 2 and Figure 7 , a through hole matching with the lever 26 is formed on the surface of the movable cutting blade 10. A rubber pad is provided on the inner wall of the through hole. The rubber pad is pressed together with the lever 26. The setting of the rubber pad can prevent water from entering the sliding groove 20.

[0032] During use, the device can be integrally moved into the river channel to be cleaned. Then, the hydraulic cylinder 4 can be started to adjust the inclination angles of the mounting frame 3, the support frame 5 and the crawler 29, so that one end of the crawler 29 is located under the water surface of the river channel. When cleaning the waterweeds in the river channel, the motor can be started. The operation of the motor drives the rotating plate 7 to rotate. The rotation of the rotating plate 7 drives the connecting rod 8 to move. The movement of the connecting rod 8 drives the support plate 9 to move. The support plates 9 on the left and right sides will move up and down along with the moving cutting mechanisms on the left and right sides. The moving cutting mechanism at the bottom will drive the support plate 9 at the bottom to move left and right. Thus, large waterweeds can be cut. As the device moves, the movable cutting blade 10 will fish up the waterweeds on the water surface for cutting and crushing. Subsequently, the crushed waterweeds will be transported to the waterweed box (not drawn in this application) at the rear of the device body 1 through the crawler 29;

[0033] When the moving cutting blade 10 has been used for a long time and the wear seriously affects its use, the corresponding installation mechanism can be driven to release the clamping of the severely worn moving cutting blade 10. Subsequently, a brand-new moving cutting blade 10 can be replaced. In this way, when the moving cutting blade 10 is severely worn, the corresponding severely worn moving cutting blade 10 can be replaced without replacing the entire set of cutting parts. That is, start the motor, the motor drives the driving gear 13 to operate, the operation of the driving gear 13 drives the two rack plates 14 to move, and the two rack plates 14 move towards the middle of the driving gear 13, thereby driving the two plugs 15 to leave the slots 18 and return to the inside of the grooves 19. Then, press the four levers 26 into the inside of the moving cutting blade 10. The movement of the four levers 26 into the inside of the moving cutting blade 10 drives the connected moving rods 25 to move. The movement of the moving rods 25 pulls the clamping blocks 21 to move into the sliding grooves 20. At this time, the clamping blocks 21 leave the clamping grooves 27 and return to the sliding grooves 20. As the clamping blocks 21 move, the springs 24 are compressed. At this time, the moving cutting blade 10 can be pulled outwards, driving the end of the moving cutting blade 10 to leave the installation groove 11;

[0034] Immediately, insert the end of the brand-new moving cutting blade 10 into the installation groove 11. When inserting into the installation groove 11, it is still necessary to press the four levers 26 to drive the four clamping blocks 21 to move into the moving cutting blade 10. Then, insert the end of the moving cutting blade 10 into the installation groove 11. At this time, release the levers 26. Under the action of the spring 24, the clamping blocks 21 are driven to extend out of the sliding grooves 20 and snap into the clamping grooves 27. At this time, the position of the moving cutting blade 10 is initially positioned. Subsequently, drive the motor, and the motor reversely drives the driving gear 13 to rotate. The driving gear 13 drives the two rack plates 14 and the plugs 15 to move into the slots 18, and the replacement and fixation of the moving cutting blade 10 can be completed.

[0035] Although this specification is described according to the embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
