Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of asphalt scraping devices, and in particular to a heated asphalt scraping device. Background Technology
[0002] With the large-scale use of asphalt pavement structures on highways in my country, the performance of asphalt pavements is receiving increasing attention. Pavement quality and performance directly affect the load-bearing capacity and service life of roads. Therefore, conducting asphalt tests before pavement engineering design and construction is an indispensable part of ensuring pavement quality and performance. During softening point and ductility tests, the asphalt mold samples need to be manually scraped after pouring to ensure a relatively smooth surface.
[0003] In traditional methods, tests for softening point, ductility, elastic recovery, and SBS content of modified asphalt commonly involve scraping off excess asphalt using a scraper with direct heating. This method cannot strictly control the heating temperature; excessively high or low temperatures can affect the test results for softening point, ductility, elastic recovery, and SBS content of modified asphalt to varying degrees. Furthermore, when using a copper scraper to remove asphalt, the asphalt adheres to the scraper, making it difficult to clean and affecting the subsequent asphalt coating effect. Utility Model Content
[0004] The purpose of this invention is to solve the problems of existing heating devices that cannot strictly control the heating temperature, which can affect the softening point, ductility, elastic recovery, and SBS content test results of asphalt to varying degrees when the temperature is too high or too low. Furthermore, when using a copper scraper to scrape asphalt, the asphalt will stick to the copper scraper, which is inconvenient to clean and affects the subsequent asphalt coating effect. Therefore, a heated asphalt scraping device is proposed.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A heated asphalt scraping device includes a handle, an extension tube fixedly connected to one end of the handle, a scraper blade fixedly connected to the other end of the extension tube, a sliding sleeve slidably fitted onto the outer wall of the extension tube, a cleaning sleeve fixedly connected to the other end of the sliding sleeve, the cleaning sleeve slidably fitted onto the scraper blade, notches provided on both sides of the sliding sleeve, and sliding grooves provided on the top and bottom of the cleaning sleeve, a sliding frame slidably connected between the two sliding grooves, a cleaning shovel fixedly connected to the inner wall of one end of the sliding frame, and a lever fixedly connected to the outer wall of the other end of the sliding frame, and an installation groove provided inside the scraper blade, in which a temperature sensor and a resistance heating element are installed.
[0007] Furthermore, the handle has a mounting cavity, in which a circuit board and a battery are fixedly connected.
[0008] Furthermore, the battery is electrically connected to the circuit board, the resistance heating element, and the temperature sensor.
[0009] Furthermore, one end of the handle is snapped with an end cap.
[0010] Furthermore, a temperature control switch is fixedly connected to the top outer wall of the handle, and the temperature control switch is electrically connected to the temperature sensor.
[0011] Furthermore, a temperature display is provided on the top of the handle, and the temperature display is electrically connected to the temperature sensor.
[0012] Furthermore, the circuit board is electrically connected to the temperature sensor, resistance heating element, battery, temperature control switch, and digital temperature display.
[0013] The beneficial effects of this utility model are as follows:
[0014] 1. The scraper blade is heated by a resistance heating element, and then the temperature of the scraper blade is monitored by a temperature sensor. The information is transmitted to a processor on a circuit board for processing. The processor on the circuit board then controls the heating temperature of the resistance heating element, thereby better softening the asphalt.
[0015] 2. By pulling the sliding frame, the cleaning shovel is moved, which scrapes the front end of the cleaning sleeve and the front end of the scraper blade, thereby scraping off the asphalt adhering to the front end of the cleaning sleeve and the front end of the scraper blade, thus facilitating the cleaning of the scraper blade.
[0016] 3. By pulling the sliding frame, the cleaning shovel is moved, causing it to scrape against the front end of the cleaning sleeve and the front end of the scraper blade, thereby scraping off the asphalt adhering to the front end of the cleaning sleeve and the front end of the scraper blade, so as to thoroughly clean the asphalt.

The cleaning sleeve 5 is slidably sleeved with the scraper blade 3. Pushing the sliding sleeve 4 downward causes the cleaning sleeve 5 to move downward, thereby scraping the residual asphalt on the scraper blade 3. The sliding sleeve 4 has notches 6 on both sides to facilitate the downward movement of the cleaning sleeve 5. The top and bottom of the cleaning sleeve 5 have sliding grooves 7, and a sliding frame 8 is slidably connected between the two sliding grooves 7. A cleaning shovel 9 is welded to the inner wall of one end of the sliding frame 8, and a cleaning shovel 9 is welded to the outer wall of this end of the sliding frame 8. A lever 10 is connected, which pulls the sliding frame 8 to move the cleaning shovel 9, causing the cleaning shovel 9 to scrape the front end of the cleaning sleeve 5 and the front end of the scraper blade 3, thereby scraping off the asphalt adhering to the front end of the cleaning sleeve 5 and the front end of the scraper blade 3. The scraper blade 3 has an installation groove, in which a temperature sensor 11 and a resistance heating element 12 are installed. The handle 1 has an installation cavity, in which a circuit board 13 and a battery 14 are fixed by bolts. The resistance heating element 12 heats the scraper blade 3. Then, the temperature of the scraper blade 3 is monitored by the temperature sensor 11, and the information is transmitted to the processor on the circuit board 13 for processing. Then, the processor on the circuit board 13 controls the heating temperature of the resistance heating element 12.
[0024] The battery 14 is electrically connected to the circuit board 13, the resistance heating element 12, and the temperature sensor 11. The temperature sensor 11 is an ATS1-82. One end of the handle 1 is snapped with an end cap 15. The top outer wall of the handle 1 is fixed with a temperature control switch 16 by bolts. The temperature control switch 16 is electrically connected to the temperature sensor 11 and the resistance heating element 12. The top of the handle 1 is equipped with a temperature digital display 17, which is electrically connected to the temperature sensor 11. The heating temperature is displayed on the temperature digital display 17. The circuit board 13 is electrically connected to the temperature sensor 11, the resistance heating element 12, the battery 14, the temperature control switch 16, and the temperature digital display 17.
[0025] The working principle of this embodiment is as follows: When in use, firstly, the scraper blade 3 is heated by the resistance heating element 12, then the handle 1 is held and the excess asphalt is scraped off by the scraper blade 3. During the scraping process, the temperature of the scraper blade 3 is monitored by the temperature sensor 11 and the information is transmitted to the processor on the circuit board 13 for processing. Then, the processor on the circuit board 13 controls the heating temperature of the resistance heating element 12.
[0026] When cleaning the scraper blade 3, push the sliding sleeve 4 downward to move the cleaning sleeve 5 downward, so that the cleaning sleeve 5 scrapes on the scraper blade 3, thereby scraping off the residual asphalt on the scraper blade 3. Then pull the sliding frame 8 to move the cleaning shovel 9, so that the cleaning shovel 9 scrapes on the front end of the cleaning sleeve 5 and the front end of the scraper blade 3, thereby scraping off the asphalt adhering to the front end of the cleaning sleeve 5 and the front end of the scraper blade 3.
