[0069] For further information, see Attachment Figure 7 In a specific implementation, the top surface of the sandbox monomer 21 has a sand collecting port 2101 corresponding to the lower end of the sand conveying pipe 5, and the bottom surface of the sandbox monomer 21 is rotatably connected to the sand collecting box 2 through a rotating shaft 22, and the rotating shaft 22 is spaced a first preset distance from the inner peripheral side wall of the sand collecting box 2; a counterweight 23 is provided on the sandbox monomer 21 and between the rotating shaft 22 and the inner peripheral side wall of the sand collecting box 2, which is used to automatically restore the sandbox monomer 21 to the first state after the sand collecting box 2 empties the internal sand and dust in the second state.

[0070] Specifically, in order to realize the switching of the sandbox monomer 21 between the first state and the second state, in the technical solution adopted by the present invention, the bottom of the sandbox monomer 21 is rotatably connected to the sand collecting box 2 via the rotating shaft 22, the position of the rotating shaft 22 is spaced a first preset distance from the inner peripheral side wall of the sand collecting box 2, and each sandbox monomer 21 is provided with a counterweight 23 at a position between the rotating shaft 22 and the inner peripheral side wall of the sand collecting box 2. The counterweight 23 here can be a counterweight 23 piece added to the inside of the sandbox body and having a certain weight, or can also be a counterweight 23 piece fixed to the outside of the sandbox body and having a certain weight. Through the setting of the counterweight 23, when the weight of sand and dust inside the sandbox monomer 21 is lower than the preset weight Under the action of the counterweight 23, the sandbox monomer 21 maintains the first state, and when the weight of the sand and dust inside the sandbox monomer 21 is higher than the preset weight, the weight of the counterweight 23 can be overcome, and the sandbox monomer 21 can be flipped downward, thereby realizing the dumping of the internal sand and dust. After the dumping of the sand and dust is completed, the sandbox monomer 21 can automatically flip to the first state under the action of the gravity of the counterweight 23, thereby realizing the automatic and convenient switching of the sandbox monomer 21 between the first state and the second state; wherein, the counterweight 23 can be set at the bottom position of the sandbox monomer 21 close to the inner peripheral side wall of the sand collecting box 2, and its radial size in the sand collecting box 2 gradually decreases from the bottom to the top, and the specific size and shape can be set according to actual needs.

[0071] Among them, refer to the attached Figure 7 In order to increase the sand discharge speed of the sand box monomer 21 in the second state to avoid affecting the continuity of sand collection, in the technical solution adopted by the present invention, the sand box monomer 21 may include: a top surface, a bottom surface, and an inner side surface and an outer side surface connected therebetween, that is, the sand box monomer 21 is in a through state in the circumferential direction of the sand collecting box 2, and the above-mentioned sand collecting port 2101 is opened on the top surface, so that when the sand box monomer 21 is in the second state, sand and dust can be poured out from the through ports 2102 on both sides of the sand box monomer 21 and the sand collecting port 2101 at the same time, which can reduce the time that the sand box monomer 21 stays in the second state, which is beneficial to improving the continuity of sand collection and the accuracy of wind erosion monitoring.

[0072] For further information, see Attachment Figure 7 In a specific implementation, the wall surface of the sandbox monomer 21 facing the outer peripheral side wall of the sand collecting box 2 is a first arc surface 21a, and the distance from the top to the bottom of the first arc surface 21a and the outer peripheral side wall of the sand collecting box 2 gradually decreases; the wall surface of the sandbox monomer 21 facing the inner peripheral side wall of the sand collecting box 2 is a second arc surface 21b, and the second arc surface 21b is coaxial with the inner peripheral side wall of the sand collecting box 2.

[0073] Specifically, in order to facilitate the state switching of the sandbox monomer 21, in the technical solution adopted by the present invention, the top surface and the bottom surface of the sandbox monomer 21 can be set as planes respectively, or the top surface of the sandbox monomer 21 can also be set as a curved surface, and the outer side surface of the sandbox monomer 21 facing the outer peripheral side wall of the sand collecting box 2 can be set as a first arc surface 21a, and the distance from the top to the bottom of the first arc surface 21a and the outer peripheral side wall of the sand collecting box 2 gradually decreases, which can avoid the interference of the sandbox monomer 21 with the outer peripheral side wall of the sand collecting box 2 when switching the state; the inner side surface facing the inner peripheral side wall of the sand collecting box 2 can be set as a second arc surface 21b, and the second arc surface 21b and the inner peripheral side wall of the sand collecting box 2 are coaxial arc surfaces, and there is a certain interval between the two, which can increase the volume of the sand collecting monomer 31 so that it can accommodate more sand and dust.

[0074] Furthermore, in a specific implementation, the sand collector provided in this embodiment also includes: an electrostatic eliminator, which is connected to the multiple sand transport pipes 5 respectively.

[0075] Specifically, in order to improve the sand transport efficiency, in the technical solution adopted by the present invention, an electrostatic eliminator can be set to be connected to the sand transport pipe 5, so as to utilize the positive and negative charge airflows generated by the electrostatic eliminator to neutralize the static electricity carried by the sand transport pipe 5 and the sand and dust inside it, thereby achieving the purpose of eliminating static electricity, and avoiding the accumulation of sand and dust inside the sand transport pipe 5 due to the existence of static electricity, thereby improving the sand transport efficiency and the accuracy of wind erosion monitoring; the position of the electrostatic eliminator can be set in the sand collecting box 2, or can also be set inside the base 1, which is not specifically limited here, and it is sufficient to achieve the static electricity elimination effect on the sand transport pipe 5.

[0076] In the specific implementation, before deploying the sand collector, it is necessary to obtain relevant information such as dust flux, wind direction, wind speed profile, etc. in the deployment area, and adjust the height of the sand collector, the height of the tripod 8, the specifications of the sand collecting box 2 and the sand box unit 21, the counterweight 23 of the sand collecting unit 31, etc. according to the needs; after the site is leveled, a shallow pit is dug in the deployment area, the diameter of the shallow pit can be about 40 cm, and the depth can be about 20 cm. When laying out the sand collector, bury the tripod 8, the base 1 and other parts in a shallow pit. After leveling the sand collector through the leveling bubble 73, backfill the sand to fix the tripod 8 firmly, place the oil replenishing chamber 61, open the valve to complete the oil seal of the bearing 6; after installing the sand collecting box 2 on the base 1, fix the sand conveying pipe 5 on the umbrella-shaped protective shell 7 through the pipe clamp 72, and adjust the verticality of the sand conveying pipe 5; after the installation is completed, check whether the sand collecting box 2 can rotate freely relative to the base 1, whether the sand box unit 21 can be turned over, and whether the system works normally; among them, when burying the tripod 8 in the shallow pit, it is necessary to ensure that there is space in height for the sand box unit 21 in the sand collecting box 2 to discharge sand.
