One end of the cutter head 1 is bent downwards and is connected with a scraping plate 11, and the scraping plate 11 is obliquely arranged relative to the asphalt surface; when the film scraping device works, the scraping plate 11 is in line contact with the asphalt surface, so that the contact area between the scraping plate 11 and the asphalt surface is reduced, and the resistance during film scraping is reduced. The asphalt collection groove 12 is horizontally arranged on the side surface of the scraping plate 11, and the asphalt collection groove 12 is used for collecting redundant asphalt.

The heating mechanism 2 includes a housing 21, a heating element 22, and a temperature control assembly 23. The axial level of casing 21 sets up, and casing 21 one end and tool bit 1 threaded connection, the one end and the electric wire 3 fixed connection of the tool bit 1 are kept away from to casing 21.

The heating element 22 is a resistance wire which is fixedly arranged inside the shell 21.

The control panel is fixed inside the shell 21, and the display screen 232 and the keys 233 are fixed on the outer surface of the shell 21 and connected with the control panel. The worker sets the heating temperature by pressing the key 233 and transmits a signal to the control panel; after receiving the signal, the control panel starts the resistance wire to heat the cutter head 1, and meanwhile, the set heating temperature is displayed on the display screen 232, so that the control personnel can observe the cutter head conveniently. The temperature control assembly is used for heating the cutter head 1, so that the temperature of the cutter head 1 is more accurate and controllable, and the temperature of the cutter head 1 is constant.

The handle 211 is fixedly arranged on the outer wall of the shell 21, and when a worker uses the film scraping device to scrape films, the handle 211 is held by hands, so that the operation is convenient, and the situation that the button 233 is touched by mistake when the shell 21 is held by hands is avoided.

The two opposite sides of the outer wall of the shell 21 are provided with sliding grooves 212, and the two sliding grooves 212 are vertically arranged and parallel to each other. Each chute 212 is internally and slidably connected with a supporting rod 4, and the two supporting rods 4 are supported on two sides of the asphalt test sample so as to erect the shell 21 on the top of the asphalt test sample, thereby not only relieving the pressure of the wrist part of a worker during film scraping, but also enabling the film scraping process to be more stable.
