Description

Technical Field

[0001] This utility model belongs to the field of road roller technology, and in particular relates to a water spraying device for road rollers. Background Technology

[0002] Single-drum vibratory rollers are widely used in various engineering scenarios that require high-intensity compaction due to their strong excitation force and high compaction efficiency. They are especially suitable for compaction of earth subgrades and soil-rock mixed fill subgrades, thus providing a solid foundation for the subsequent laying of asphalt or cement concrete pavement.

[0003] When a single-drum vibratory roller is in operation, if the moisture content of the subgrade soil is too low, the internal friction between particles will be high, making it difficult to achieve the specified compaction degree. In addition, a lot of dust will be generated, affecting the surrounding environment. Therefore, it is necessary to spray water to moisten the subgrade soil. After the subgrade soil is moistened, when the operator drives the single-drum vibratory roller to compact the subgrade, the roller's steel wheel will stick to mud and other impurities. Therefore, a water spraying device for the roller is needed to spray water on the subgrade, road surface and roller steel wheel, which will help compact the subgrade, suppress dust, and prevent excessive impurities from sticking to the roller steel wheel. Utility Model Content

[0004] The purpose of this invention is to provide a water spraying device for road rollers, which can spray water on the subgrade, road surface and the steel wheel of the road roller, thereby facilitating subgrade compaction, suppressing dust and preventing excessive impurities from adhering to the steel wheel of the road roller, so as to solve the problems mentioned in the background art.

[0021] In the following description, embodiments of the water spraying device for road rollers of the present invention will be described with reference to the accompanying drawings.

[0022] Figure 1-5 This invention illustrates a water spraying device for a road roller according to an embodiment of the present invention. It includes a connecting plate 2 mounted on the top of the road roller 1. The connecting plate 2 is rotatably connected to the road roller 1 via a rotating shaft 3. The connecting plate 2 is a U-shaped right-angle plate. A baffle 13 is an inclined baffle. Through the cooperation of the baffle 13, a locking strip 14, and a locking groove 15, the locking strip 14 engages with the locking groove 15, inserting the locking strip 14 from the surface of the baffle 13 into the inner cavity of the locking groove 15. This limits the baffle 13 to be positioned in front of the spray pipe 4, thereby blocking the forward-spraying water when the nozzle 5 sprays water onto the steel wheel of the road roller 1. The locking groove 15 is a U-shaped groove, and two symmetrical locking grooves 15 are fixedly connected to the inner wall of the connecting plate 2. The locking strip 14 engages with the locking groove 15. A spray pipe 4 is fixedly connected to the inner wall of the connecting plate 2, and a baffle 13 is provided on the front of the spray pipe 4. Two symmetrical locking strips 14 are fixedly connected to the surface. The inlet of the spray pipe 4 extends through to the top of the connecting plate 2. Several nozzles 5 are evenly distributed in the inner cavity of the connecting plate 2. The nozzles 5 are threadedly connected to the outlet of the spray pipe 4. A water tank 6 is installed on the surface of the roller 1. A water pump 7 is fixedly installed on the surface of the roller 1. The roller 1 is a single steel drum vibratory roller. A water pumping pipe 8 is fixedly connected to the outlet of the water tank 6 through a flange. The water pumping pipe 8 is fixedly connected to the water pump 7 through a flange. A water delivery pipe 9 is threadedly connected to the inlet of the spray pipe 4. The water delivery pipe 9 is fixedly connected to the water pump 7 through a flange. Limit sleeves 10 are fixedly connected to the inner walls of the left and right sides of the connecting plate 2. Two limit seats 11 are fixedly connected to the surface of the roller 1. A pin 12 is provided in the inner cavity of one of the limit seats 11. The top of the pin 12 extends through to the top of the limit sleeve 10.

[0023] Working principle: When using this utility model, the user... Figure 1When the pin 12 is removed from the inner cavity of the limiting seat 11 and the limiting sleeve 10, the connecting plate 2 is rotated counterclockwise by the rotating shaft 3, causing the spray pipe 4 inside the connecting plate 2 to rotate counterclockwise. This rotates the connecting plate 2 and the spray pipe 4 to the right side of the roller 1, thereby aligning the limiting sleeve 10 fixedly connected to the inner wall of the connecting plate 2 with the limiting seat 11 fixedly connected to the right side of the roller 1. Then, the pin 12 is inserted into the inner cavity of the limiting sleeve 10 and the limiting seat 11, thus limiting the connecting plate 2 and the spray pipe 4 to the right side of the roller 1. On the other side, water is then pumped out of the water tank 6 via the water pump 7 and the water pipe 8. The water pump 7 then delivers the pumped water to the inner cavity of the spray pipe 4 via the water pipe 9, causing the water to spray out from the nozzle 5 at the outlet of the spray pipe 4. At this time, the road roller 1 is driven to wet the roadbed surface, which facilitates roadbed compaction and dust suppression. After the wetting work is completed, the pin 12 on the right side of the road roller 1 is removed from the limit sleeve 10 and the limit seat 11. The connecting plate 2 is rotated clockwise via the rotating shaft 3, so that the connecting plate 2 and the spray pipe 4 are rotated back to their original positions. Figure 1 The system is in a state where the connecting plate 2 and the spray pipe 4 are limited by inserting the pin 12 into the limiting sleeve 10 and the limiting seat 11. At this time, the water pump 7 delivers water from the water tank 6 to the spray pipe 4 through the water pumping pipe 8 and the water supply pipe 9, so that the water is sprayed out from the nozzle 5 and washes the steel wheel of the roller 1. This prevents too many impurities from sticking to the roller's steel wheel when the roller 1 is being driven to compact the roadbed.

[0024] In summary: This road roller uses a water spraying device, which, through... Figure 1 Remove the pin 12 from the machine. Rotate the connecting plate 2 counterclockwise via the shaft 3 to rotate the spray pipe 4 to the right side of the roller 1, aligning the limiting sleeve 10 on the inner wall of the connecting plate 2 with the limiting seat 11 on the right side of the roller 1. Insert the pin 12 into the limiting sleeve 10 and the limiting seat 11. Then, pump the water from the water tank 6 to the spray pipe 4, causing the water to spray from the nozzle 5. Drive the roller 1 to wet the roadbed surface, which facilitates roadbed compaction and dust suppression. After the wetting work is completed, return the spray pipe 4 to its original position. Figure 1 This state ensures that the water sprayed from nozzle 5 is sprayed onto the steel wheel of roller 1, thereby preventing excessive impurities from adhering to the steel wheel when roller 1 is compacting the roadbed.
