Description

Technical Field

[0001] This invention belongs to the field of culvert maintenance technology, and more specifically, this invention relates to a device for cleaning silt from the bottom of narrow culverts. Background Technology

[0002] Over time, culverts accumulate large amounts of silt, including sand, soil, dead branches, plastic bags, and animal carcasses. Ordinary equipment is too large to enter culverts for dredging, especially in narrow culverts with smaller openings (such as 1.5m x 1.5m or 2m x 2m box-shaped culverts). Dredging in these narrow culverts relies on manual labor, which is both labor-intensive and inefficient. Existing technologies disclose a culvert dredging device (publication number CN115710969A) and a culvert bottom silt cleaning device (publication number CN213773543 U). The design of these existing dredging devices utilizes various crushing structures to agitate and break down the silt and debris into a fluid, which is then flushed away with water or suctioned away under negative pressure. However, this design not only involves complex crushing structures but also results in poor flushing or suction dredging effectiveness, low efficiency, and difficulty in removing uncrushed or missed stones and heavy, hard objects. Summary of the Invention

[0003] One object of the present invention is to address at least the aforementioned deficiencies and to provide at least the advantages that will be described later.

[0004] This invention provides a device for cleaning silt from the bottom of narrow culverts. A hydraulic system drives a scraper bucket at the front end of a telescopic arm to extend into the culvert and scrape out the silt, thus cleaning the culvert. This invention uses scraping, pushing, or shoveling methods to quickly remove silt such as sand, gravel, hard soil, dead branches, plastic bags, and animal carcasses from culverts. The equipment has a simple structure and high cleaning efficiency.

[0005] This invention provides a device for cleaning silt from the bottom of narrow culverts, comprising:

[0006] A scraper bucket includes a scraper and side plates disposed on both sides of the scraper.

[0007] The telescopic boom is controlled to extend and retract via a hydraulic system. The scraper bucket is located at the extension end of the telescopic boom. When the telescopic boom extends the scraper bucket into the culvert, the bottom edge of the scraper blade of the scraper bucket abuts against the bottom of the culvert, and the two side plates abut against the side walls of the culvert, forming an interception surface for scraping out the silt inside the culvert.

[0008] A lifting mechanism, the lifting end of which is connected to the fixed arm of the telescopic arm, is used to support the telescopic arm and control the height of the telescopic arm;

[0009] The vehicle body, which is used for support and transportation, is equipped with the lifting mechanism and hydraulic system.

[0010] Preferably, the scraper of the scraper bucket is a plate that can extend and retract along the width direction. The scraper includes a first scraper, a second scraper, an intermediate sleeve plate, and a crossbeam. The intermediate sleeve plate has openings on its left and right sides and corresponding receiving cavities for slidingly fitting the first scraper and the second scraper, respectively. The upper end of the intermediate sleeve plate is fixedly provided with a crossbeam, and the lower side of the crossbeam is provided with a sliding groove that matches the upper end of the first scraper and the second scraper. The telescopic end of the telescopic arm is connected to the crossbeam.

[0011] Preferably, the scraper also includes two first hydraulic cylinders, which are respectively disposed on both sides of the intermediate sleeve plate; the telescopic ends of the two first hydraulic cylinders are respectively disposed on the two sides away from the first scraper and the second scraper, and the non-telescopic ends of the two first hydraulic cylinders are disposed on both sides of the intermediate sleeve plate.

[0012] Preferably, the scraper also includes a second hydraulic cylinder, the non-extension end of which is disposed on the non-extension end of the first hydraulic cylinder, and the extension end of the second hydraulic cylinder is connected to the side plate to drive the two side plates to open and close.

[0013] Preferably, a third hydraulic cylinder or reinforcing rib is provided between the uppermost lifting section of the lifting mechanism and the fixed arm of the telescopic boom.

[0014] Preferably, the vehicle body includes a sludge collection box and a hopper. The sludge collection box is an open box with a groove in the middle for lowering the telescopic arm. Two parallel slide rails are provided on both sides of the rear of the sludge collection box. The hopper can slide up and down between the opening on the top of the sludge collection box and the bottom of the sludge collection box via the slide rails and the drive device, for loading sludge into the sludge collection box.

[0015] Preferably, the hopper is an open-top box, and the side wall of the hopper is provided with a slider that matches the slide rail.

[0016] Preferably, the hopper has two intermediate partitions corresponding to the groove in the car body. The two intermediate partitions are distributed in an isosceles triangle in the hopper. The base of the isosceles triangle is located on the side wall where the slider is located. The length of the base is greater than or equal to the width of the groove. The height of the two intermediate partitions is greater than the height of the hopper side wall opposite the base.

[0017] Preferably, the hopper is configured such that the sidewalls of the slider and the opposite sidewalls are foldable and can be opened and closed to load and dump sludge into the truck bed.

[0018] Preferably, it also includes a high-pressure water gun, which is mounted on the movable arm at the outermost end of the telescopic boom, with the nozzle facing upward or circumferentially.

[0019] The present invention has at least the following beneficial effects:

[0020] First, this invention uses a scraper bucket or scraper shovel to quickly remove silt, such as sand, gravel, hard soil, dead branches, plastic bags, and animal carcasses, from culverts. The equipment has a simple structure and high cleaning efficiency.

[0036] Figure 1-2 An implementation of a silt removal device for the bottom of a narrow culvert is shown, which includes:

[0037] The scraper bucket 7 includes a scraper 10 and side plates 9 disposed on both sides of the scraper 10;

[0038] The telescopic arm 6 is controlled to extend and retract via a hydraulic system. The scraper bucket 7 is located at the telescopic end of the telescopic arm 6. When the telescopic arm 6 extends the scraper bucket 7 into the culvert, the bottom edge of the scraper blade 10 of the scraper bucket 7 abuts against the bottom of the culvert, and the two side plates 9 abut against the side walls of the culvert, forming an interception surface for scraping out the silt in the culvert.

[0039] The lifting mechanism 3 has its lifting end connected to the fixed arm 61 of the telescopic arm 6, and is used to support the telescopic arm 6 and control the height of the telescopic arm 6.

[0040] The vehicle body, which is used for support and transportation, is equipped with the lifting mechanism 3 and the hydraulic system.

[0041] The usage process of this invention is as follows: When the applicable situation requires the device of this invention to clean the silt at the bottom of narrow culverts, the applicable situations are generally box-shaped culverts with a length, width and height of 10-20m×1.5m×1.5m or 10-20m×2m×2m, etc. The vehicle body is equipped with a lifting mechanism 3, a hydraulic system, a telescopic arm 6 and a scraper bucket 7, which arrive at the site together. During the journey, the telescopic arm 6 and the scraper bucket 7 are in a retracted state for easy movement. After the vehicle body is adjusted to a stable position, the lifting mechanism 3 is controlled to support the telescopic arm 6 at a predetermined height, and the telescopic arm 6 is controlled to extend the scraper bucket 7 into the culvert. After the scraper bucket 7 reaches the predetermined position, the edge of the scraper blade 10 of the scraper bucket 7 abuts against the bottom of the culvert, and the two sides of the scraper blade 10 (that is, the side plates 9 set on both sides of the scraper blade 10) also abut against the side wall of the culvert to form an interception surface. Then, the telescopic arm 6 is controlled to retract, scraping out the silt in the culvert. This invention uses a scraper bucket 7 or a scraper shovel to quickly remove silt, such as sand, gravel, hard soil, dead branches, plastic bags, and animal carcasses, from culverts. The equipment of this invention has a simple structure and high cleaning efficiency.

[0042] Based on the above implementation methods, such as Figure 3-4 As shown, the scraper 10 of the scraper bucket 7 is a plate that can extend and retract along the width direction. The scraper 10 includes a first scraper 10, a second scraper 10, an intermediate sleeve plate 11, and a crossbeam 8. The intermediate sleeve plate 11 has openings on its left and right sides and corresponding receiving cavities for slidingly fitting the first scraper 10 and the second scraper 10, respectively. The crossbeam 8 is fixedly mounted on the upper end of the intermediate sleeve plate 11. The lower side of the crossbeam 8 is provided with a sliding groove 12 that matches the upper end of the first scraper 10 and the second scraper 10, thereby forming a scraper 10 that can extend and retract along the width direction. The telescopic end of the telescopic arm 6 is connected to the crossbeam 8. The technical details of the connection method between the telescopic end of the telescopic arm 6 and the crossbeam 8 are as follows: conventionally, a fixed connection would be considered. However, this invention can use a hinge and a hinged hydraulic cylinder. That is, the telescopic end of the telescopic arm 6 is hinged to the crossbeam 8, and the fixed arm 61 of the telescopic arm 6 is hinged to the intermediate sleeve plate 11 by a hydraulic cylinder, so as to realize the folding and retraction or tilting scraping of sludge by the scraper bucket 7 and the telescopic arm 6. The scraper bucket 7 of this invention can extend and retract along the width direction, which helps to improve the scope of application and dredging effect, and meets the needs of narrow culverts of different widths.

[0043] Based on the above implementation, the scraper 10 also includes two first hydraulic cylinders 13, which are respectively arranged on both sides of the intermediate sleeve plate 11; the telescopic ends of the two first hydraulic cylinders 13 are respectively arranged on the two sides away from the first scraper 10 and the second scraper 10, and the non-telescopic ends of the two first hydraulic cylinders 13 are arranged on both sides of the intermediate sleeve plate 11, so as to realize the control and limit of the width of the scraper bucket 7.

[0044] Based on the above implementation methods, such as Figure 5As shown, the scraper bucket 7 also includes a second hydraulic cylinder 14. The non-telescopic end of the second hydraulic cylinder 14 is disposed on the non-telescopic end of the first hydraulic cylinder 13. The telescopic end of the second hydraulic cylinder 14 is connected to the side plate 9 to drive the two side plates 9 to open and close, further expanding the scope of application.

[0045] Based on the above implementation, a third hydraulic cylinder 5 or a reinforcing rib is provided between the uppermost lifting section of the lifting mechanism 3 and the fixed arm 61 of the telescopic arm 6; when the lifting end of the lifting mechanism 3 is fixedly connected to the telescopic arm 6, a reinforcing rib is fixedly connected between the uppermost lifting section and the fixed arm 61 of the telescopic arm 6; when the lifting end of the lifting mechanism 3 is hingedly connected to the telescopic arm 6, a third hydraulic cylinder 5 is hingedly connected between the uppermost lifting section and the fixed arm 61 of the telescopic arm 6, so as to realize the adjustment of the tilt of the telescopic arm 6 as needed, thereby improving the applicability and usage effect.

[0046] Based on the above implementation methods, such as Figure 6-8 As shown, the vehicle body includes a sludge collection box 1 and a hopper 15. The box 1 is an open box with a groove 4 in the middle for lowering the telescopic arm 6. Two parallel slide rails 18 are provided on both sides of the rear of the box 1. The hopper 15 can slide up and down between the opening on the top of the box 1 and the bottom of the box 1 through the slide rails 18 and the drive device, which is used to load sludge into the box 1, further improving the applicability and sludge removal effect.

[0047] Based on the above implementation, the hopper 15 is a box with an opening at the top, and a slider 19 matching the slide rail 18 is provided on the side wall of the hopper 15.

[0048] Based on the above implementation, the hopper 15 is provided with two intermediate partitions 20 corresponding to the groove 4 of the carriage 1. The two intermediate partitions 20 are distributed in an isosceles triangle within the hopper 15. The base of the isosceles triangle is located on the side wall where the slider 19 is located, and the length of the base is greater than or equal to the width of the groove 4. The height of the two intermediate partitions 20 is greater than the height of the front baffle 17. Referring to the attached drawings, the side wall where the slider 19 is located is the rear baffle 21, and the opposite side of the rear baffle 21 is the front baffle 17. The base of the isosceles triangle formed by the two intermediate partitions 20 is located on the rear baffle 21, and the apex of the isosceles triangle is located on the front baffle 17. The apex is the front end 16 of the partition. During use, the scraper 7 pushes the sludge into the front baffle 17. Guided by the two intermediate partitions 20, the sludge enters the two sides separated by the two intermediate partitions 20, that is, the receiving chambers on both sides of the hopper 15. This facilitates the sludge being poured from the rear baffle 21 into the car body 1, preventing it from entering the groove 4 and improving the usage effect.

[0049] Based on the above implementation, the hopper 15 is configured with the sidewalls of the slider 19 and their opposite sidewalls as foldable opening and closing structures to load and dump sludge into the carriage 1. Referring to the attached diagram, the sidewalls of the slider 19 and their opposite sidewalls are the corresponding rear baffle 21 and front baffle 17. The driving device for folding and opening / closing can be a hydraulic cylinder. In use, the hopper 15 is slid down along the slide rail 18 to the bottom of the carriage 1 and placed on the ground. The front baffle 17 is folded outwards to contact the ground, forming a steep slope between the ground and the hopper 15. The scraper 7 scrapes the cleaned sludge from the slope into the hopper 15. Once full, the front baffle 17 is folded inwards to close, driving the hopper 15 upwards along the slide rail 18 to the opening on the carriage 1. The rear baffle 21 is then folded outwards to dump the sludge into the carriage 1. This process is repeated to facilitate the transport of the cleaned sludge to a designated location.

[0050] Based on the above implementation methods, such as Figure 9 As shown, it also includes a high-pressure water gun 22, which is installed on the movable arm 62 at the outermost end of the telescopic arm 6, with the nozzle facing upward or circumferentially, to flush down the silt on the culvert wall and further improve the cleaning effect.

[0051] Although embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the specification and embodiments. It can be applied to various fields suitable for the present invention. Further modifications can be readily implemented by those skilled in the art.
