Description

Technical Field

[0001] This utility model relates to the technical field of road roller cleaning devices, specifically a water spraying anti-sticking device for a double-drum road roller. Background Technology

[0002] In the compaction process, a double-drum roller and a rubber-tired roller are used together for compaction. However, double-drum rollers are prone to wheel sticking during high-temperature compaction, which affects their normal operation. To address this, water is typically sprayed onto the double-drum roller to form a water film, thus mitigating the wheel sticking problem.

[0003] According to a public announcement of a double-drum roller and its water spraying device (Announcement No.: CN212000500U), the above application ensures that the outer surface of the steel drum is covered with a water film during the rolling of asphalt pavement by setting the double-drum roller water spraying device as described in any of the above embodiments in the double-drum roller, thereby eliminating the phenomenon of roller sticking.

[0004] However, in actual use, while the above-mentioned equipment can reduce sticking during water spraying, the water evaporates quickly in high-temperature environments, which can easily cause some impurities to adhere to the surface of the steel wheel, affecting the anti-sticking effect of subsequent water spraying. In view of this, we propose a water spraying anti-sticking device for double steel wheel rollers. Utility Model Content

[0005] The purpose of this invention is to provide a water spray anti-sticking device for a double-drum roller to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a water spraying anti-sticking device for a double-drum roller, comprising a body, a connecting frame fixedly installed on the lower surface of the body, a steel wheel rotatably connected to the side wall of the connecting frame via a round rod, a liquid storage tank fixedly installed on the upper surface of the body, a pump body fixedly installed on the upper surface of the body, a spray head connected to the surface of the pump body via a connecting pipe, and a cleaning mechanism provided on the outer side of the body, the cleaning mechanism comprising: Mounting block, the mounting block is fixedly mounted on the lower surface of the machine body, one end of the reset spring is fixedly connected to the inner wall of the mounting block, and a bending rod is fixedly connected to the end of the reset spring away from the inner wall of the mounting block; A support rod frame is fixedly installed on the lower surface of the mounting block. The arc surface of the support rod frame is rotatably connected to a mounting plate via a rotating shaft. The outer side of the mounting plate is provided with bristles.

[0007] Preferably, the brush bristles are detachably mounted on the surface of the mounting plate via a connecting plate, and the brush bristles are arranged at an angle on the surface of the connecting plate.

[0008] Preferably, the lower surface of the mounting block is provided with a bending groove, the shape of which is adapted to the shape of the bending rod, so that the bending rod can move inside the bending groove.

[0009] Preferably, the number of bending rods is set to several, and the several bending rods are fixedly installed on the upper surface of the mounting plate in a linear array. The multiple bending rods, together with the reset spring, enable the brush bristles on the mounting plate to fit against the arc surface of the steel wheel.

[0010] Preferably, the spray nozzle of the spray head is aligned with the upper arc surface of the steel wheel, and the length of the mounting plate is adapted to the length of the steel wheel, so that the brush bristles can clean the arc surface of the steel wheel.

[0011] Preferably, an auxiliary mechanism is provided on the outer side of the machine body. The auxiliary mechanism includes a guide rod, which is fixedly installed on the side wall of the mounting plate, and a disc is fixedly installed on the arc surface of the rod.

[0012] Preferably, a protrusion is fixedly installed on the arc surface of the disc, and the arc surface of the disc and the guide rod are on the same horizontal straight line, so that the disc rotates so that the protrusion can contact the arc surface of the guide rod.

[0013] Compared with the prior art, this utility model provides a water spray anti-sticking device for a double drum roller, which has the following beneficial effects: 1. This double-drum roller uses a water spray anti-sticking device. It features a cleaning mechanism where the pump drives the spray head to spray treatment liquid onto the curved surface of the drum. Simultaneously, under the elastic action of the return spring, the end of the bending rod-linked mounting plate dynamically adheres to the curved surface of the drum. The mounting plate can adaptively rotate around the support frame, ensuring the brush bristles continuously contact the curved surface for cleaning. The bristles are distributed in an inclined radial pattern with predetermined gaps, facilitating the removal of impurities. Drums are installed on both sides of the machine body, thus achieving anti-adhesion self-cleaning of the drum's curved surface.

[0014] 2. The water spray anti-sticking device for this double-drum roller has an auxiliary mechanism. The disc rotates synchronously with the steel wheel, and its circumferential protrusions periodically abut against the arc surface of the guide rod, driving the mounting plate to move back and forth. This accelerates the shedding of impurities from the brush bristles and reduces the probability of adhesion to the arc surface. At the same time, the dynamic interference between the protrusions and the guide rod transmits vibration to the mounting plate, achieving brush bristle cleaning and dust removal, further reducing the residue of impurities on the arc surface of the steel wheel.

[0017] like Figures 1-4 As shown, this utility model provides a technical solution: a water spraying anti-sticking device for a double steel drum roller, including a body 1, a connecting frame 2 fixedly installed on the lower surface of the body 1, a steel wheel 5 rotatably connected to the side wall of the connecting frame 2 via a round rod, a liquid storage tank 6 fixedly installed on the upper surface of the body 1, a pump body 7 fixedly installed on the upper surface of the body 1, a spray head 8 connected to the surface of the pump body 7 via a connecting pipe, and a cleaning mechanism 3 provided on the outer side of the body 1, the cleaning mechanism 3 including a mounting block 301, a return spring 302, a bending rod 303, a mounting plate 304, a support rod frame 305, and bristles 306.

[0018] In one embodiment of this utility model, the mounting block 301 is fixedly mounted on the lower surface of the body 1. One end of the reset spring 302 is fixedly connected to the inner wall of the mounting block 301. A bending rod 303 is fixedly connected to the end of the reset spring 302 away from the inner wall of the mounting block 301. A support rod frame 305 is fixedly mounted on the lower surface of the mounting block 301. The arc surface of the support rod frame 305 is rotatably connected to the mounting plate 304 through a rotating shaft. Brush bristles 306 are provided on the outer side of the mounting plate 304.

[0019] In addition, the bristles 306 are detachably mounted on the surface of the mounting plate 304 via connecting plate bolts, facilitating replacement of the bristles 306 after prolonged use. The bristles 306 are arranged at an angle on the surface of the connecting plate. A bending groove is provided on the lower surface of the mounting block 301, the shape of which matches the shape of the bending rod 303, allowing the bending rod 303 to move within the bending groove.

[0020] In an embodiment of this utility model, a plurality of bending rods 303 are provided, and the plurality of bending rods 303 are fixedly installed on the upper surface of the mounting plate 304 in a linear array. The arrangement of the plurality of bending rods 303 in conjunction with the reset spring 302 allows the bristles 306 on the mounting plate 304 to fit against the arc surface of the steel wheel 5.

[0021] It is worth noting that the machine body 1 can be installed at the front and rear ends of the double drum roller, and together with the cleaning mechanism 3, it can clean the surface of the drum 5 of the steel drum.

[0022] The spray nozzle of the spray head 8 is aligned with the upper arc surface of the steel wheel 5. The length of the mounting plate 304 is adapted to the length of the steel wheel 5, facilitating the cleaning of the arc surface of the steel wheel 5 by the bristles 306. An auxiliary mechanism 4 is provided on the outer side of the machine body 1. The auxiliary mechanism 4 includes a guide rod 401, which is fixedly installed on the side wall of the mounting plate 304. A disc 402 is fixedly installed on the arc surface of the rod. A protrusion is fixedly installed on the arc surface of the disc 402, and the disc 402 and the arc surface of the guide rod 401 are on the same horizontal straight line. Thus, the disc 402 rotates so that the protrusion can contact the arc surface of the guide rod 401.

[0023] In this invention, during use, the pump body 7 drives the spray head 8 to spray the treatment liquid onto the arc surface of the steel wheel 5. Simultaneously, under the elastic action of the return spring 302, the bending rod 303 dynamically adheres to the end of the mounting plate 304 in conjunction with the arc surface of the steel wheel 5. The mounting plate 304 can adaptively rotate around the support rod frame 305 to ensure that the bristles 306 continuously contact the arc surface to perform cleaning. The bristles 306 are distributed in an inclined radial pattern and retain a predetermined gap, which facilitates the removal of impurities and their easy fall off, thereby achieving anti-adhesion cleaning of the arc surface of the steel wheel 5.

[0024] Furthermore, the disc 402 rotates synchronously with the steel wheel 5, and its circumferential protrusion periodically abuts against the arc surface of the guide rod 401, driving the mounting plate 304 to move back and forth, causing the impurities peeled off by the bristles 306 to fall off more quickly and reducing the probability of adhesion to the arc surface; at the same time, the dynamic interference of the protrusion and the guide rod 401 transmits vibration to the mounting plate 304, realizing the cleaning and dust removal of the bristles 306, further reducing the residue of impurities on the arc surface of the steel wheel 5.

[0025] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
