[0034] As shown in Figure 6 and Figure 7 , the teaching aid further comprises a scraping assembly, the scraping assembly comprises a first motor 25, an arc-shaped plate 26, a second motor 27, a first electric push rod 28 and a scraper 29, the first motor 25 is installed on the upper side of the sand storage frame 3, the output shaft of the first motor 25 is connected with the arc-shaped plate 26, one end of the arc-shaped plate 26 is installed with the second motor 27, the output shaft of the second motor 27 is installed with the first electric push rod 28, and the telescopic rod of the first electric push rod 28 is connected with the scraper 29.

[0035] When it is needed to scrape the sand particles in the sand storage frame 3, the first motor 25 is controlled by the control panel 6 to drive the arc-shaped plate 26 to rotate by a specified angle, the arc-shaped plate 26 drives the second motor 27 to rotate by a specified angle, so that the output shaft of the second motor 27 is vertically aligned with the center position of the sand storage frame 3, then the first electric push rod 28 is controlled by the control panel 6 to drive the scraper 29 to descend by a specified distance, so that the scraper 29 contacts with the sand particles in the sand storage frame 3, and then the second motor 27 is controlled by the control panel 6 to drive the first electric push rod 28 and the scraper 29 to rotate by a specified number of turns, so that the scraper 29 can scrape the sand particles in the sand storage frame 3; after the sand particles are scraped, the first electric push rod 28 is controlled by the control panel 6 to drive the scraper 29 to ascend by a specified distance to reset, and the first motor 25 is controlled to drive the arc-shaped plate 26 to reverse by a specified angle to reset, and the arc-shaped plate 26 drives the second motor 27 to reverse by a specified angle to reset.

[0036] Since the sand particles in the sand storage frame 3 may contain some sundries after being used for a long time, a conveying assembly is designed to transport all the sand particles in the sand storage frame 3 into the box 7 for filtering. Figures 8-10As shown, the conveying assembly comprises a square tube 31, a rubber tube 3102, a rotating baffle 32, a second electric push rod 33 and a rubber cloth 34. The square hole 30 is formed in the sand storage frame 3. The square tube 31 is connected to the bottom of the sand storage frame 3 and is arranged on one side of the square hole 30. The top of the square tube 31 is in communication with the square hole 30. The upper part of one side of the square tube 31 is provided with a notch 3101. The bottom of the square tube 31 is connected with the rubber tube 3102. One end of the rubber tube 3102 is connected with the top of the box body 7. The square tube 31 is in communication with the box body 7 through the rubber tube 3102. When the box body 7 vibrates, the rubber tube 3102 will deform, which can prevent the vibration of the box body 7 from being transmitted to the square tube 31. The rotating baffle 32 is rotatably connected in the square hole 30. The top of the support seat 2 is provided with an avoiding groove which is located below the arc-shaped end of the rotating baffle 32, that is, the top of the support seat 2 is provided with an avoiding groove corresponding to the rotating track of the rotating baffle 32 to provide the required space when the rotating baffle 32 rotates. One end of the rotating baffle 32 is arc-shaped, and the center of the arc is coincided with the rotating axis of the rotating baffle 32 to ensure that it is in smooth contact with the inner wall of the square hole 30 without movement interference during the opening and closing process. One end of the rotating baffle 32 is located in the notch 3101. The rubber cloth 34 is connected between the two sides of the rotating baffle 32 and the sand storage box 3. The second electric push rod 33 is rotatably connected to the lower part of the square tube 31. The telescopic rod of the second electric push rod 33 is rotatably connected to the bottom of the rotating baffle 32.

[0037] Initially, as shown in Figure 9 the rotating baffle 32 is in a closed state, that is, the rotating baffle 32 blocks the square hole 30 to prevent the sand particles in the sand storage frame 3 from falling down through the square hole 30. The top of the rotating baffle 32 is flush with the inner bottom of the sand storage frame 3. At this time, the rubber cloth 34 is in a retracted state. When it is necessary to filter the sand particles in the sand storage frame 3, as shown in Figure 10As shown, firstly, the second electric push rod 33 is controlled by the control panel 6 to drive the rotating baffle 32 to rotate downwards and open, so that the rotating baffle 32 no longer blocks the square hole 30, and the rubber baffle 34 will unfold as the rotating baffle 32 rotates. At this time, the rubber baffle 34 can block the space between the opposite sides of the rotating baffle 32 and the sand storage frame 3, so that the rotating baffle 32 and the rubber baffles 34 on both sides together form a downward inclined channel; then, the scraper 29 is controlled by the control panel 6 to descend a specified distance, so that the bottom of the scraper 29 contacts the bottom of the sand storage frame 3, and then the scraper 29 is controlled to rotate, so that the scraper 29 can sweep the sand particles in the sand storage frame 3, so that all the sand particles in the sand storage frame 3 pass through the square hole 30 into the sand storage frame 3. The sand falls to the top of the rotating baffle 32 and rolls down along the top of the rotating baffle 32 into the square tube 31. Then, it falls down through the square tube 31 and the rubber tube 3102 into the box 7 for filtration. After all the sand in the sand storage frame 3 has entered the box 7, the second electric push rod 33 can be controlled by the control panel 6 to drive the rotating baffle 32 to rotate upward and reset, closing the square hole 30. At this time, the rubber baffle 34 is retracted. After all the sand has been filtered, the sand can be sent back to the sand storage frame 3 through the recycling component. The scraper 29 can be lowered a specified distance by the control panel 6 to scrape the sand in the sand storage frame 3. Finally, the scraper 29 can be reset by the control panel 6.

[0038] like Figure 1 As shown, the teaching aid also includes a crossbar 35 and a camera 36. The crossbar 35 is connected to the upper part of one side of the support rod 5, and the camera 36 is installed at one end of the crossbar 35. The camera 36 is located directly above the center of the sand storage frame 3. After the students have placed the miniature models in the sand storage frame 3, the teacher can control the camera 36 through the control panel 6 to take pictures and record the miniature models placed in the sand storage frame 3, so as to facilitate the comparison of the results of multiple tests later.

[0039] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
