Description

Technical Field

[0001] This utility model belongs to the field of road roller technology, specifically relating to a road roller device for municipal construction. Background Technology

[0002] In modern municipal engineering, road construction, and small-scale site development, walk-behind rollers have become a commonly used road compaction device due to their flexibility and convenience. However, some problems have emerged during actual use. During the rolling process, the rollers frequently come into contact with various granular construction materials, making them prone to accumulating particulate matter. This accumulating material not only alters the smoothness of the roller surface, affecting the uniformity of subsequent compaction, but also, over time, can lead to accelerated localized wear and shorten the roller's service life.

[0003] To address the issue of impurities adhering to the rollers, existing walk-behind rollers typically incorporate cleaning mechanisms such as scrapers to promptly remove impurities from the roller surface. However, this solution introduces new problems. Impurities cleaned by the scrapers fall directly onto the road surface being compacted. In actual construction, the road surface often requires multiple compaction operations. This makes it highly likely that the roller will come into contact with impurities that have fallen onto the road surface again during subsequent rolling processes, increasing the frequency of impurities affecting the roller's operation and further reducing the quality and efficiency of the compaction work. Utility Model Content

[0004] This utility model provides a road roller device for municipal construction, which solves the problem of impurities repeatedly adhering to the roller and affecting the road rolling effect.

[0005] This utility model provides the following technical solution: including a frame, a roller, two mounting brackets, an operating arm and a control handle. Two collection boxes are provided at the bottom of the frame. Each collection box has a scraper hinged to one side. A torsion spring is provided between the scraper and the corresponding collection box. Both scrapers are slidably connected to the outside of the roller. The two collection boxes are symmetrically distributed. An inner sliding plate is slidably connected to the inner wall of each collection box.

[0006] The machine frame is equipped with a water tank at the top and two water inlet pipes at the bottom. Each of the two water inlet pipes has several nozzles on one side, and the nozzles are angled to the roller.

[0007] The frame has four side support feet at its bottom, and an auxiliary roller is installed between every two side support feet. The two auxiliary rollers are symmetrically distributed, and the two collection boxes are respectively installed on the side walls of the corresponding two side support feet.

[0008] The collection box has a strip-shaped hole at its top, and an L-shaped drive plate is installed at the top of the inner slide plate. The L-shaped drive plate is slidably connected to the inner wall of the strip-shaped hole.

[0009] The inner wall of the collection box is equipped with a guide rod, which passes through the side wall of the inner slide plate, and the inner slide plate is slidably connected to the side wall of the guide rod.

[0010] Each of the two collection boxes has two discharge pipes installed at the bottom, and the side walls of the discharge pipes are threaded with bottom covers, with permeable nets installed at the bottom of the bottom covers.

[0011] The discharge pipe has a fixed ring fixedly connected to its side wall, and a connecting strap is fixedly connected to one side of the bottom cover. One end of the connecting strap is fixedly connected to a limiting ring, which is sleeved on the outside of the discharge pipe and is positioned above the fixed ring.

[0012] The beneficial effects of this utility model are: by using two collection boxes and two scrapers in combination, it solves the problem that in the traditional method of scraping off impurities and letting them fall directly onto the road surface, the roller is very likely to come into contact with the impurities that have fallen onto the road surface again during the subsequent rolling process when the road surface is compacted multiple times. This increases the number of times that impurities affect the roller's operation and further reduces the quality and efficiency of the compaction work.

[0013] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0020] Please see Figures 1-5 The present invention provides the following technical solution: including a frame 1, a roller 11, two mounting brackets 111, an operating arm 12 and a control handle 121. Two collection boxes 2 are provided at the bottom of the frame 1. Each of the two collection boxes 2 is hinged to a scraper 21 on one side. A torsion spring is provided between the scraper 21 and the corresponding collection box 2. Both scrapers 21 are slidably connected to the outside of the roller 11. The two collection boxes 2 are symmetrically distributed. Both collection boxes 2 have an inner sliding plate 22 slidably connected to their inner walls.

[0021] In this implementation scheme: the frame 1 is connected to the roller 11 via two mounting brackets 111. The roller 11 compacts the road surface by rolling. The handles at both ends of the operating arm 12 facilitate the operator's grip and use of the equipment. The control handle 121 controls the working status of the equipment. Two collection boxes 2 are located on both sides of the roller 11, clamping the roller 11. The collection boxes 2 support the corresponding scrapers 21. The collection boxes 2 do not contact the roller 11. The scrapers 21 are driven to rotate towards the roller 11 by corresponding torsion springs, enabling the scrapers 21 to stably scrape the side wall of the roller 11, reducing the impact on the uniformity of subsequent compaction and improving the service life of the equipment. The scrapers 21 face upwards. The inclined design requires the impurities adhering to the roller 11 to rotate over another collection box 2 before reaching the corresponding scraper 21 for scraping and cleaning. After cleaning, the impurities on the roller 11 slide down the scraper 21 into the collection box 2 for centralized storage. By controlling the inner slide plate 22 to slide, the impurities inside the collection box 2 can be squeezed towards both ends of the collection box 2 for easy removal and cleaning. This solves the problem of traditional methods where impurities are scraped off and fall directly onto the road surface. During multiple compaction operations, the roller 11 is easily exposed to impurities that have fallen onto the road surface during subsequent rolling processes, increasing the number of times impurities affect the operation of the roller 11 and further reducing the quality and efficiency of the compaction work.

[0022] A water tank 13 is installed at the top of the frame 1, and two water inlet pipes 14 are installed at the bottom of the frame 1. Several nozzles 141 are provided on one side of each of the two water inlet pipes 14, and the nozzles 141 correspond to the angle of the roller 11. The water tank 13 stores water for cleaning the roller 11. The two water inlet pipes 14 spray water onto the roller 11 through the corresponding nozzles 141, which facilitates the cleaning of the outside of the roller 11 and is beneficial to the maintenance of the equipment.

[0023] Four side support feet 15 are installed at the bottom of the frame 1. An auxiliary roller 151 is installed between every two side support feet 15. The two auxiliary rollers 151 are symmetrically distributed. Two collection boxes 2 are installed on the side walls of the corresponding two side support feet 15. The four side support feet 15 are divided into two groups and are in contact with the ground through the auxiliary rollers 151. The two auxiliary rollers 151 and the corresponding side support feet 15 together provide auxiliary support for the device to prevent the equipment from tipping over.

[0024] The top of the collection box 2 has a strip-shaped hole 23, and the top of the inner slide plate 22 is equipped with an L-shaped drive plate 221. The L-shaped drive plate 221 is slidably connected to the inner wall of the strip-shaped hole 23. The strip-shaped hole 23 guides and limits the sliding of the L-shaped drive plate 221, so that the L-shaped drive plate 221 and the inner slide plate 22 can maintain a stable sliding path and posture. The extension of the L-shaped drive plate 221 makes it easy for personnel to control and use it.

[0025] A guide rod 24 is installed on the inner wall of the collection box 2. The guide rod 24 passes through the side wall of the corresponding inner slide plate 22. The inner slide plate 22 is slidably connected to the side wall of the guide rod 24. The guide rod 24 guides and limits the sliding of the inner slide plate 22 to prevent the inner slide plate 22 from tilting or deviating, thereby further improving the stability during use.

[0026] Two discharge pipes 3 are installed at the bottom of each of the two collection boxes 2. The side wall of the discharge pipe 3 is threaded with a bottom cover 31, and a water-permeable net 32 ​​is installed at the bottom of the bottom cover 31. The two discharge pipes 3 are located at both ends of the bottom of the corresponding collection box 2, so that the inner slide plate 22 can push the impurities to the top of the discharge pipe 3 for discharge. The discharge pipe 3 is sealed by the bottom cover 31. When it is unscrewed, the water is discharged. The water-permeable net 32 ​​filters and discharges the water in the collection box 2.

[0027] A fixing ring 33 is fixedly connected to the side wall of the discharge pipe 3, and a connecting strap 34 is fixedly connected to one side of the bottom cover 31. A limiting ring 341 is fixedly connected to one end of the connecting strap 34. The limiting ring 341 is sleeved on the outside of the discharge pipe 3 and is located above the fixing ring 33. The fixing ring 33 is a fixed design. The fixing ring 33 limits the limiting ring 341. The limiting ring 341 and the connecting strap 34 enable the discharge pipe 3 and the bottom cover 31 to be stably connected, preventing the bottom cover 31 from being lost when disassembling and discharging impurities.

[0028] The working principle and usage process of this utility model are as follows: During use, the operator controls the equipment to move forward, and the roller 11 compacts the road surface. Particles and impurities adhere to the roller 11. The scraper 21 is tilted upwards, so the impurities on the roller 11 need to rotate over another collection box 2 to reach the corresponding scraper 21 position for scraping and cleaning. After the impurities on the roller 11 are cleaned, they slide down the scraper 21 into the inside of the collection box 2 for centralized storage. The operator manually controls the L-shaped drive plate 221 to drive the inner slide plate 22 to slide, so that the impurities inside the collection box 2 can be squeezed towards both ends of the collection box 2 for easy removal and cleaning. This solves the problem that in the traditional method, when impurities are scraped off and fall directly onto the road surface, the roller 11 is very likely to come into contact with the impurities that have fallen onto the road surface again during the subsequent rolling process when the road surface is compacted multiple times. This increases the number of times that impurities affect the operation of the roller 11, further reducing the quality and efficiency of the compaction work.
