Description

Technical Field

[0001] The invention relates to the technical field of silt-clearing robots, and in particular to an anti-blocking and silt-clearing device for road engineering construction. Background Art

[0002] In road construction, the drainage system is a key component to ensure the safety and durability of road use. However, during construction and use, drainage pipes are easily blocked by silt and debris, resulting in poor drainage and even causing problems such as road surface waterlogging and waterlogging, which seriously affect the normal operation of the road and the safety of the surrounding environment. Currently, dredging robots are used to clean up blockages and silt in drainage pipes.

[0003] A general dredging robot includes a body, a bucket, a main shaft, an auger, a power system, a lighting system, an identification system, a dredging system, etc. When in use, the dredging robot is placed in the area to be dredged, and then the power system first drives the main shaft to rotate, and then drives the auger on the main shaft to rotate. The power system then drives the body to move by driving the tracks. At this time, the bucket will shovel the blockage to the auger, which will transport it to the dredging system to clear the blockage. Through the lighting system and the identification system, the staff can remotely observe the blockage situation through the control terminal.

[0004] As in the prior art, an invention patent with authorization announcement number CN112575839B discloses a dredging robot, including a power system and a sewage discharge system; the power system includes a body carrier, a hydraulic station, a hydraulic valve, an oil pipe, a track motion system, a baffle, and an oil cylinder, and the hydraulic station is provided with a power motor, an oil tank, and an oil pump; the power motor provides power for the oil pump, and the oil pump draws the oil in the oil tank out and supplies it to the oil pipe, the hydraulic valve controls the oil circuit of the oil pipe, and the oil pipe supplies the power oil to the track motion system, the baffle is provided on the outside of the track motion system, and the body carrier is arranged above the track motion system.

[0005] The existing dredging robots have certain defects when in use. When the existing dredging robots encounter stone-like blockages during the cleaning process, if the blockages are directly transported to the dredging pipes through the auger, the dredging pipes may be damaged due to the sharp edges and corners of the blockages, resulting in a reduction in the service life of the dredging pipes. At the same time, the forced transportation of such blockages directly through the auger may also cause damage to the auger, causing the entire dredging operation to come to a standstill, affecting the continuity and efficiency of the dredging task.

DETAILED DESCRIPTION

[0032] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0033] See also Figure 1-Figure 12A blocking and desilting device for road engineering construction comprises a bucket 1 and a main shaft 2 connected inside the bucket 1, a first rotating shaft 3 is rotatably connected to the inner wall of the front side of the bucket 1, a rolling roller 4 is fixedly connected to the outer wall of the No. 1 rotating shaft 3, a plurality of rolling blocks 5 are fixedly connected to the outer wall of the rolling roller 4, a connecting shaft 6 is rotatably connected to the outer wall of the bucket 1, the connecting shaft 6 is fixedly connected to one end of the main shaft 2, a driving wheel 7 is fixedly connected to the outer wall of the connecting shaft 6, a No. 1 transmission belt 8 is connected to the outer wall of the driving wheel 7, one end of the No. 1 rotating shaft 3 passes through the outer wall of the bucket 1 and is connected to a connecting assembly, the connecting assembly is connected to the No. 1 transmission belt 8, a crushing assembly and a cutting assembly are connected to the inner wall of the bucket 1, the crushing assembly and the cutting assembly are both connected to the connecting assembly, a wear-resistant plate 9 is detachably connected to the front surface of the bucket 1, and the wear-resistant plate 9 corresponds to the position of the rolling roller 4.

[0034] The anti-blocking and silting device for road engineering construction of the present invention, when in operation, the main shaft 2 will drive the No. 1 rotating shaft 3 to rotate clockwise through the driving wheel 7, the No. 1 transmission belt 8 and the connecting assembly, and then drive the rolling roller 4 to rotate clockwise. When the bucket 1 shovels up hard blockages, the blockages will move along the bottom surface of the bucket 1 under the action of gravity and enter the gap between the rolling roller 4 and the wear-resistant plate 9. Under the squeezing of the rolling block 5, the blockages will be crushed and broken, effectively weakening the sharp edges of the blockages, so that the sharp edges of the blockages are removed, thereby reducing the potential harm of the blockages. The crushed blockages will move along the bottom surface of the bucket 1, and enter the silting pipeline and the collecting device driven by the auger connected to the main shaft 2; using the rolling roller 4 The wear-resistant plate 9 can crush the blockage, reduce the size of the blockage, and weaken the sharp edges of the blockage, thereby reducing the risk of the blockage damaging the dredging pipe and the auger, increasing the service life of the dredging pipe and the auger, and ensuring the stability of continuous operation; the detachable wear-resistant plate 9 can protect the bucket 1, and can directly withstand the huge pressure and wear generated by the operation of the rolling roller 4, reducing the deformation and wear of the bucket 1 caused by long-term pressure, thereby protecting the structural integrity of the bucket 1 and increasing the service life of the bucket 1. The detachable nature of the wear-resistant plate 9 means that when it suffers from severe wear or damage, only the wear-resistant plate 9 needs to be replaced instead of the entire bucket 1, which simplifies the maintenance process and reduces maintenance costs and time.

[0035] As a preferred technical solution of the present invention, the crushing assembly includes a No. 2 rotating shaft 10 and a fine pressing roller 11. The No. 2 rotating shaft 10 is rotatably connected to the inner wall of the bucket 1. The fine pressing roller 11 is sleeved on the outer wall of the No. 2 rotating shaft 10. One end of the No. 2 rotating shaft 10 passes through the outer wall of the bucket 1 and is connected to the connecting assembly. The shortest distance between the outer wall of the fine pressing roller 11 and the surface of the wear-resistant plate 9 and the outer wall of the rolling roller 4 is equal. The height of the No. 2 rotating shaft 10 is lower than that of the No. 1 rotating shaft 3.

[0036] Specifically, after the initially crushed blockage passes between the crushing roller 4 and the wear-resistant plate 9, it immediately enters the action area of ​​the fine pressing roller 11 driven by the second rotating shaft 10. Driven by the connecting component, the second rotating shaft 10 and the fine pressing roller 11 rotate clockwise, thereby performing a secondary crushing on the blockage, further reducing the size and sharpness of the blockage; at the same time, since the blockage after the first crushing may be carried away from the wear-resistant plate 9 by sewage, etc., the blockage will enter between the crushing roller 4 and the fine pressing roller 11 for a secondary crushing. The shortest distance between the outer wall of the fine-pressing roller 11 and the surface of the wear-resistant plate 9 and the outer wall of the rolling roller 4 is equal. Therefore, the blockages produced by the secondary rolling between the rolling roller 4 and the fine-pressing roller 11, and the secondary rolling between the wear-resistant plate 9 and the fine-pressing roller 11 are of the same size, thereby ensuring that the fine-pressing roller 11 is subjected to uniform force. This design is conducive to uniform distribution of pressure, so that the blockages are continuously and evenly crushed between the two rolling links, avoiding the problem of incomplete treatment or excessive crushing due to uneven pressure, and improving crushing efficiency and consistency.

[0037] As a preferred technical solution of the present invention, the cutting assembly includes a No. 4 rotating shaft 17 and a cutting disk 18. The No. 4 rotating shaft 17 is rotatably connected to the inner wall of the bucket 1, and a plurality of cutting disks 18 are equidistantly and fixedly connected to the outer wall of the No. 4 rotating shaft 17. The height of the No. 4 rotating shaft 17 is higher than the No. 1 rotating shaft 3 and lower than the main shaft 2. One end of the No. 4 rotating shaft 17 passes through the outer wall of the bucket 1 and is connected to the connecting assembly.

[0038] Specifically, when encountering flexible or entangled blockages such as cloth, plant branches, leaves, etc., the cutting disc 18 will cut these blockages into smaller and easier-to-handle fragments, thereby preventing these blockages from being entangled in the auger or blocking the clearing pipe. At the same time, since the size of the fragments after cutting is reduced, it is easier to pass through the pipe, thus avoiding large pieces of material blocking the pipe and ensuring the continuity and efficiency of the dredging process.

[0039] As a preferred technical solution of the present invention, the connecting component includes a driven wheel 12, a third rotating shaft 13, a driving wheel 14, a main gear 15, a slave gear 16, a second transmission belt 29 and a third transmission belt 30. The third rotating shaft 13 is fixedly connected to one side of the bucket 1. The outer wall of the third rotating shaft 13 is rotatably connected to two driving wheels 14. The main gear 15 is fixedly connected between the two driving wheels 14. One end of the first rotating shaft 3 is fixedly connected to the driven wheel 12. One end of the second rotating shaft 10 is fixedly connected to two driven wheels 12. One end of the fourth rotating shaft 17 is fixedly connected to the slave gear 16. One end of the first transmission belt 8 is connected to a driving wheel 14. The other driving wheel 14 is connected to a driven wheel 12 connected to the fourth rotating shaft 17 through the second transmission belt 29. Another driven wheel 12 connected to the fourth rotating shaft 17 is connected to the driven wheel 12 connected to the first rotating shaft 3 through the third transmission belt 30. The main gear 15 is meshed with the slave gear 16.

[0040] Specifically, when the main shaft 2 rotates clockwise, the driving wheel 7 rotates clockwise accordingly, and then the two driving wheels 14 and the main gear 15 rotate clockwise under the drive of the No. 1 transmission belt 8, and the driving wheel 14 drives the No. 2 rotating shaft 10 and the No. 1 rotating shaft 3 to rotate clockwise in turn through the No. 2 transmission belt 29 and the No. 3 transmission belt 30, and then drives the rolling roller 4 and the fine pressing roller 11 to rotate clockwise to achieve multiple rolling. At this time, the main gear 15 drives the slave gear 16 to rotate counterclockwise, and then drives the No. 4 rotating shaft 17 and the cutting disc 18 to rotate counterclockwise to achieve cutting. This design ensures that all actions in the entire device, from rolling, secondary rolling to cutting, can be carried out in a coordinated and consistent manner, and each step is closely linked, thereby improving the overall efficiency and smoothness of the dredging operation. Through the designed transmission system, the present invention realizes precise power transmission from the main shaft 2 to each component, ensures that each component can work synchronously as needed, improves the continuity and efficiency of the dredging operation, and reduces the complexity and energy consumption required to drive each component individually.

[0041] As a preferred technical solution of the present invention, a plurality of rolling grooves 20 are provided on the surface of the wear-resistant plate 9, and connecting plates 21 are fixedly connected on both sides of the wear-resistant plate 9. A plurality of mounting holes 22 corresponding to the positions are provided on both sides of the bucket 1 and the two connecting plates 21, and bolts 23 are rotatably connected in the mounting holes 22 on the bucket 1.

[0042] Specifically, the design of the rolling groove 20 on the wear-resistant plate 9, by forming a specific groove structure on the surface of the wear-resistant plate 9, can not only guide and accommodate the debris generated during the rolling process, and prevent these debris from gathering inside the bucket 1 and affecting the subsequent dredging efficiency, but also help to increase the contact area during rolling, making the rolling process more efficient, reducing the possibility of blockages directly impacting the bucket 1, and protecting the bucket 1 structure; the wear-resistant plate 9 can be quickly replaced by utilizing the mutual cooperation of the bolts 23 and the mounting holes 22. When the wear-resistant plate 9 is worn due to long-term operation and needs to be replaced, the operator only needs to loosen the bolts 23 to easily remove the old wear-resistant plate 9, and then tighten the bolts 23 after installing the new wear-resistant plate 9. The whole process is simple and quick, without the need for complicated disassembly and assembly steps, which significantly reduces the difficulty and time cost of maintenance.

[0043] As a preferred technical solution of the present invention, a fixing plate 24 is fixedly connected to the bottom surface of the bucket 1, a fixing groove 25 is opened on one side of the fixing plate 24, and a plug plate 26 corresponding to the position of the fixing groove 25 is fixedly connected to one side of the wear-resistant plate 9.

[0044] Specifically, by utilizing the cooperation between the fixing plate 24 and the insert plate 26, the wear-resistant plate 9 can be flattened to prevent the middle part of the wear-resistant plate 9 from bending or warping. When installing the wear-resistant plate 9, first insert the insert plate 26 into the fixing groove 25, and then tighten the bolt 23, so as to achieve precise positioning of the wear-resistant plate 9, reduce additional wear caused by unevenness, and extend the service life of the wear-resistant plate 9.

[0045] As a preferred technical solution of the present invention, a plurality of cutting plates 19 are fixedly connected between two adjacent cutting discs 18 .

[0046] Specifically, the cutting plate 19 can be used to further shred the cut blockage, making the cutting operation more precise. At the same time, the cutting plate 19 can also block the blockage. After the blockage enters the bucket 1 from above the rolling roller 4, it will fall between the rolling roller 4 and the fine pressing roller 11 under the obstruction and drive of the counterclockwise moving cutting plate 19, ensuring that the blockage can be fully crushed and broken.

[0047] As a preferred technical solution of the present invention, a protective cover 27 is fixedly connected to one side of the outer wall of the bucket 1 , and the driving wheel 7 , the first transmission belt 8 and the connecting assembly are all located inside the protective cover 27 .

[0048] Specifically, during the dredging process, the working environment may contain a large amount of dirt, sand, gravel and other debris. The protective cover 27 can prevent these foreign objects from entering the connecting components, avoiding foreign objects from getting stuck in the transmission belt or damaging key components such as the axle, reducing equipment failure rate, and extending maintenance cycles and overall service life; the protective cover 27 can also reduce the erosion of dust and moisture on the connecting components, prevent the lubricant from evaporating too quickly, help maintain the good lubrication state of the transmission system, reduce wear, and reduce maintenance costs and frequency.

[0049] As a preferred technical solution of the present invention, a reinforcing rib 28 is fixedly connected to the inner wall of the protective cover 27 .

[0050] Specifically, the reinforcing ribs 28 disperse and bear external pressure, effectively reducing the risk of deformation of the protective cover 27 when it is hit or squeezed, improving the rigidity and impact resistance of the overall structure, and improving the protection effect of the connection components.

[0051] As a preferred technical solution of the present invention, a No. 5 rotating shaft 33 is rotatably connected inside the bucket 1, and the No. 5 rotating shaft 33 is located between the main shaft 2 and the No. 4 rotating shaft 17. One end of the No. 5 rotating shaft 33 passes through the side wall of the bucket 1 and is fixedly connected to a rotating wheel 32. The rotating wheel 32 and the driving wheel 7 are connected by a No. 4 transmission belt 31. A plurality of equally spaced arc scrapers 34 are fixedly connected to the outer wall of the No. 5 rotating shaft 33, and an elastic scraper strip 35 is fixedly connected to the end of the arc scraper 34.

[0052] Specifically, when the main shaft 2 drives the entire dredging device to operate, it will drive the fifth shaft 33 to rotate clockwise through the No. 4 transmission belt 31, thereby driving the arc scraper 34 to rotate clockwise. The arc scraper 34 can fit the inner wall of the bucket 1 for continuous scraping and sweeping, which helps to quickly move the blockages generated after rolling, crushing and cutting to the auger, and discharge them through the auger and the dredging pipeline, avoiding the accumulation of these blockages in the bucket 1, thereby ensuring the continuous and efficient operation of the rolling, crushing and cutting components, and improving the continuity and efficiency of the overall operation; the arc surface of the arc scraper 34 helps to improve its efficiency in driving the blockages, and the elastic scraper strip 35 can adjust the contact pressure according to the slight unevenness or deformation of the inner wall of the bucket 1, ensuring a close fit with the inner wall of the bucket 1 during the scraping process, and maintaining a good scraping effect even in the face of slight deformation or irregular surface of the inner wall of the bucket 1.

[0053] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
