The top of the rotating shaft 52 is connected to a tray 53. A test cylinder 4 is placed on the tray 53. The staff loads the asphalt to be tested into the test cylinder 4 and slides the test cylinder 4 along the plurality of rollers 3 on the support plate 2 onto the tray 53. The arrangement of the plurality of rollers 3 makes it easier for the staff to place the test cylinder 4. After the test cylinder 4 is placed, the motor 51 is started. The motor 51 drives the rotating shaft 52 to rotate. The rotating shaft 52 drives the tray 53 to rotate. The tray 53 drives the test cylinder 4 above it to rotate. The test cylinder 4 can make the temperature on its surface more uniform through rotation.

[0026] In this embodiment, through the setting of the rotating device 5, during the high and low temperature test of the test cylinder 4 and the asphalt inside it, by rotating, each part of itself can evenly approach the condensing pipe 61 or the heating sheet 71, making the transfer of cold and hot temperatures more uniform and improving the efficiency of temperature transfer.

[0027] Embodiment 2

[0028] Please refer to Figure 4 As shown in the figure, a cooling component 6 is arranged inside the box body 1. The cooling component 6 includes a condensing pipe 61. The condensing pipe 61 is installed on the left inner wall of the box body 1. A defroster 64 is sleeved on the surface of the condensing pipe 61. The bottom of the defroster 64 is connected to a connecting frame 63. The connecting frame 63 is slidably installed on the left inner wall of the box body 1. The bottom of the connecting frame 63 is connected to a sliding bracket 62. The sliding bracket 62 is slidably installed on the inner wall of the box body 1. An annular chute is formed on the surface of the rotating shaft 52. The sliding bracket 62 is slidably connected to the annular chute of the rotating shaft 52 through a ball. When the rotating shaft 52 rotates, the rotating shaft 52 drives the sliding bracket 62 to perform vertical reciprocating motion through the cooperation of the annular chute and the ball. When the sliding bracket 62 performs vertical reciprocating motion, it drives the defroster 64 to perform vertical reciprocating motion through the connecting frame 63. The defroster 64 can continuously remove the frost on the surface of the condensing pipe 61 during the reciprocating motion.

[0029] Furthermore, please refer to Figures 5-6As shown in the figure, a heating component 7 is arranged inside the box body 1. The heating component 7 includes a heating sheet 71. The heating sheet 71 is installed on the right inner wall of the box body 1. Four gears 73 are rotatably installed on the right inner wall of the box body 1. The four gears 73 are respectively located on both sides of the heating sheet 71. Four flow disturbing fans 74 are respectively installed on the four gears 73. The outer surface of the right end of the sliding bracket 62 is connected with two racks 72. The two racks 72 are both slidably installed on the right inner wall of the box body 1. The two racks 72 are respectively engaged with the four gears 73. While the sliding bracket 62 performs vertical reciprocating motion, the sliding bracket 62 drives the two racks 72 to perform vertical reciprocating motion. When the two racks 72 are moving, they respectively drive the four gears 73 to rotate. The four gears 73 respectively drive the four flow disturbing fans 74 to rotate. The four flow disturbing fans 74 disturb the air inside the box body 1 by rotation.

[0030] In this embodiment, through the setting of the cooling component 6, the defroster 64 can continuously scrape the frost on the surface of the condensing pipe 61 through vertical reciprocating motion, avoiding the thick frost on the surface of the condensing pipe 61 after long-term use, which may lead to increased power and affect the refrigeration efficiency. Through the setting of the heating component 7, the four flow disturbing fans 74 can continuously disturb the air inside the box body 1 by rotation, making the temperature distribution inside the box body 1 more uniform, so that the temperature transferred from the heating sheet 71 to the surface of the test cylinder 4 is more uniform, improving the accuracy of the high and low temperature test results.

[0031] When the high and low temperature test chamber for asphalt testing of the present utility model is in use, the staff loads the asphalt to be tested into the test cylinder 4, and slides the test cylinder 4 onto the sliding tray 53 along the multiple rollers 3 on the support plate 2. The setting of the multiple rollers 3 makes it more labor-saving for the staff to place the test cylinder 4.

The defroster 64 can continuously remove the frost on the surface of the condensing pipe 61 during the reciprocating motion; while the sliding bracket 62 performs vertical reciprocating motion, the sliding bracket 62 drives the two racks 72 to perform vertical reciprocating motion. When the two racks 72 are moving, they respectively drive the four gears 73 to rotate, and the four gears 73 respectively drive the four turbulence fans 74 to rotate. The four turbulence fans 74 disturb the air inside the box body 1 through rotation; through the setting of the rotating device 5, during the high and low temperature test of the test cylinder 4 and the asphalt inside it, through rotation, each part of itself can evenly approach the condensing pipe 61 or the heating sheet 71, making the transfer of hot and cold temperatures more uniform and improving the efficiency of temperature transfer; through the setting of the cooling component 6, the defroster 64 can continuously scrape off the frost on the surface of the condensing pipe 61 through vertical reciprocating motion, avoiding the thick frost on the surface of the condensing pipe 61 after long-term use, which may lead to an increase in power and affect the refrigeration efficiency; through the setting of the heating component 7, the four turbulence fans 74 can continuously disturb the air inside the box body 1 through rotation, making the temperature distribution inside the box body 1 more uniform, so that the temperature transferred from the heating sheet 71 to the surface of the test cylinder 4 is more uniform, and improving the accuracy of the high and low temperature test results.
