Description

Technical Field

[0001] The utility model relates to the field of road surface cleaning tools, in particular to a road surface mud cleaning device. Background Art

[0002] As a key technology for geotechnical engineering investigation, geological drilling technology is now quite mature. Various industries and regions have formulated corresponding geotechnical engineering investigation specifications based on their own characteristics and needs. In the construction and maintenance of airport pavement engineering, investigation work plays an indispensable role. During the drilling process, in order to keep the drill bit in normal working condition and improve drilling efficiency, water is usually connected to the drill bit to cool the drill bit, clean the hole and reduce the wear of the drill bit. The operation method of rinsing the drill mouth will produce a large amount of mud on the pavement after the drilling investigation is completed.

[0003] If the mud generated during the airport pavement engineering survey is not cleaned in time, mud blocks will be left after the water in the mud evaporates, which will not only affect the cleanliness of the airport pavement, but also pose a threat to flight safety. Therefore, the survey of the airport pavement engineering needs to be completed in the shortest possible time, and the mud generated during the survey also needs to be properly disposed of as soon as possible to ensure the safe operation of the airport. There are some pavement cleaning equipment in the prior art, such as floor scrubbers, but in airport areas that have been put into operation, large mechanical equipment is generally prohibited from entering, and tap water is not convenient to use. This creates a major obstacle to the cleaning of rock and soil waste in the large airport area, posing a hidden danger to the pavement flatness and flight safety. Utility Model Content

[0027] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0028] In the process of cleaning the airport pavement, especially the removal of mud, it is inconvenient for large equipment to enter the airport area, and the use of traditional methods such as shoveling and sweeping has the problem of low efficiency and poor cleaning effect. Based on this, this embodiment provides a pavement mud cleaning device, which mainly includes a water tank 1, a scraper 4 and a handle 8, wherein the water tank 1 is used as the main structure, and a water-containing cavity is formed inside, rollers 6 are provided on both sides of the front end of the water tank 1, the scraper 4 is installed at the rear end of the water tank 1 through a fixing hoop 3, and the handle 8 is connected to the front end of the water tank 1 through a joint 7.

[0029] In this embodiment, front and rear refer to the direction in which the roller 6 supports and drives the water tank 1 to move. The direction in which the roller 6 moves toward the position of the handle 8 is the front, and the direction in which the roller 6 moves toward the moving position of the scraper 4 is the rear.

[0030] The water tank 1 is used as the main structure. By adjusting the amount of water in the cavity, the weight of the water tank 1 can be adjusted, thereby changing the load weight applied to the scraper 4. When the handle 8 is held for operation, if the road surface is mud or muddy water with good fluidity, the amount of water in the water tank 1 can be reduced or no water can be added, thereby reducing the pressure on the scraper 4 and facilitating the lifting operation; if the road surface is mud with poor fluidity, the water tank 1 in the water tank 1 can be raised, and the weight of the water tank 1 can be increased to increase the pressure on the scraper 4, thereby improving the scraping effect of the scraper 4 on the mud.

[0031] The scraper 4 is connected to the water tank 1. The water tank 1 not only provides the necessary weight for the scraper 4 so that it can more effectively fit the road surface to scrape off the mud, but also the water stored in the cavity formed inside the water tank 1 can be released through the water outlet 5 to moisten the relatively dry or less fluid mud for subsequent processing.

[0032] Rollers 6 are installed on both sides of the front end of the water tank 1, so that the whole device can be easily moved when there is no need to scrape mud. The scraper 4 arranged at the rear end can ensure that the scraper 4 can evenly scrape mud when it fits the road surface through the design of the U-shaped structure. At the same time, the opening of the U-shaped structure faces the front end of the water tank 1, achieving a gathering effect and improving the water collection capacity of the scraper 4, so as to facilitate the mud to be driven to the lawn, drainage ditch, etc. outside the road surface.

[0033] The handle 8 is detachably connected to different docking pieces on the joint 7 at the front end of the water tank 1. When the handle 8 is connected to the lower docking piece 9, the axis of the handle 8 is parallel to the bottom surface of the water tank 1. At this time, when the handle 8 is held, the axis of the handle 8 and the bottom surface of the water tank 1 are both in an inclined state. The scraper 4 is attached to the road surface under the weight of the water tank 1 to scrape mud, and the roller 6 does not touch the ground; when the handle 8 is connected to the upper docking piece 10, the axis of the handle 8 is distributed at an angle to the bottom surface of the water tank 1, such as Figure 2 As shown, the axis of the handle 8 and the bottom surface of the water tank 1 can be at an angle of 120°, 135° or other angles. When the handle 8 is held for pulling or pushing, the angle setting between the handle 8 and the water tank 1 can make the scraper 4 tilt when the handle 8 is in a tilted state, thereby facilitating the transfer of the entire device.

[0034] The weight of the water tank 1 and the U-shaped structure design of the scraper 4 ensure that the scraper 4 can scrape away mud evenly and efficiently when it fits the road surface, thereby improving the cleaning efficiency. The detachable design of the handle 8 and the docking piece can switch the working state, so that the scraper 4 can be easily lifted when the device needs to be transferred, reducing contact with the ground, reducing the difficulty of transfer, and improving the transfer efficiency.

[0035] During the mud cleaning process, some mud has poor fluidity due to low water content, which makes it difficult to scrape off and affects the cleaning efficiency. Figure 1As shown, a water outlet hole is arranged on the bottom surface of the water tank 1, and the mud attached to the road surface after the mud is dried is moistened through the water outlet 5 to form mud, so that the scraper 4 can scrape off the mud.

[0036] In addition, there are multiple water outlets 5, which are distributed in sequence and at intervals in a direction parallel to the rotation axis of the roller 6, so as to increase the coverage of water discharged from the water outlets 5 and improve the wetting and scraping effects.

[0037] like Figure 2 and Figure 3 As shown, a water inlet is provided on the top surface of the water tank 1, and the water inlet is sealed with a water tank cover 2. A plurality of water outlets 5 are provided at the bottom of the water tank 1. In order to facilitate the control of the water outlets 5, a sealed water tank cover 2 is used. When the water outlets 5 need to be drained, the water tank cover 2 is opened or loosened so that the water in the water tank 1 can be discharged under the action of air pressure. When the water outlets 5 do not need to be drained, the water tank cover 2 is tightened. Under the action of air pressure, the water cannot be discharged from the water outlets 5. The purpose of controlling the water outlets 5 to drain or not to drain is achieved by operating the water tank cover 2.

[0038] The rear end of the water tank 1 is provided with an arc-shaped protrusion so that the rear end surface of the water tank 1 forms an arc-shaped surface. The fixing hoop 3 is distributed along the rear end surface of the water tank 1, so that the fixing hoop 3 forms a U-shaped structure distribution that adapts to the scraper 4, which is convenient for the installation and replacement of the scraper 4. The top of the fixing hoop 3 is fixed to the water tank 1, and a slot is opened at the bottom. The fixing hoop 3 can be made of a metal plate. The track of the slot is a U-shaped structure that adapts to the scraper 4. The scraper 4 is embedded in the slot of the fixing hoop 3, ensuring a firm connection between the scraper 4 and the fixing hoop 3, and improving the use effect and stability of the scraper 4.

[0039] like Figure 3 As shown, the scraper 4 is detachably connected to the fixing hoop 3, and a groove is provided on one end of the scraper 4 for contacting the road surface, so that a toothed structure is formed at one end of the scraper 4; the detachable connection can facilitate the replacement and maintenance of the scraper 4; the water tank 1 is used as a counterweight structure to increase the contact pressure between the scraper 4 and the road surface, thereby improving the scraping effect. At the same time, the scraper 4 can also be configured with a toothed structure as a toothed scraper 11, thereby improving its effect of chiseling away mud attached to the road surface, thereby improving the cleaning ability and cleaning efficiency.

[0040] like Figure 1 and Figure 2 As shown, the upper docking piece 10 and the lower docking piece 9 are respectively provided with external threads, and a threaded hole is opened at the end of the handle 8. The handle 8 is connected to the joint 7 through the cooperation of the threaded hole and the external thread, ensuring a firm connection between the handle 8 and the joint 7. At the same time, the operation is simple, and the user is convenient to quickly change the position of the handle 8.

[0041] The end of the handle 8 away from the joint 7 is connected with an annular grip 12, which provides a more comfortable gripping experience, facilitates pushing or pulling the device during the transfer process, and improves the convenience of operation.

[0042] A liquid level window is provided on the side of the water tank 1 , through which the user can intuitively understand the liquid level of the water stored in the water tank 1 , so as to facilitate timely water addition or drainage and assist in adjusting the weight of the water tank 1 .

[0043] The above detailed description of the specific implementation of the utility model is only used as an example, and the utility model is not limited to the specific implementation described above. For those skilled in the art, any equivalent modification or substitution of the utility model is also within the scope of the utility model. Therefore, the equalization, modification, improvement, etc. made without departing from the spirit and principle of the utility model should be included in the scope of the utility model.
