[0018] Unless otherwise specified, the scientific and technical terms used in this article are understood by ordinary technicians in the relevant fields.

[0019] The axial, top, bottom, radial, and other directional or orientational terms used in the devices or components herein are consistent with the relevant directions or orientations in the accompanying drawings. It should be noted that the accompanying drawings are intended to illustrate the present invention, and any equivalent solutions obtained by those skilled in the art based on these solutions fall within the scope of protection of the present invention. The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] Example 1:

[0021] See also Figure 1As shown, the sand mining device of the present invention includes a driving and direction-finding device 1 and a sand mining box suspension structure 2. The driving and direction-finding device includes a rotating device and a pointing rod 11. The rotating device includes a bearing 15 and a rotating shaft 14. The rotating shaft rotates about its own axis, and the bearing is disposed outside the rotating shaft. The pointing rod is disposed at the top of the rotating shaft 14, and the axis of the pointing rod 11 is perpendicular to the axis of the rotating shaft 14. At the same time, a balancing component 12 (such as a balancing sleeve) and a tail wing 13 are respectively disposed at both ends of the pointing rod 11, and the balancing component 12 and the tail wing 13 are respectively located on both sides of the rotating shaft. The sand mining box suspension structure 2 is mounted at the bottom end of the rotating shaft. The structure on both sides of the rotating shaft is balanced by adjusting the mounting position of the balancing component on the pointing rod.

[0022] During specific use, the above-mentioned device is fixed in the monitoring environment through a fixed plate 31 (specifically, the bearings and the rotating shaft are installed on the fixed plate 31, and the other components are assembled in the above manner), and a sand collecting box 23 is installed or placed inside or at the bottom of the sand collecting box suspension structure (an existing sand collecting box can be used, such as an existing trapezoidal hollow structure sand collecting box, the top surface of which is an exhaust net, the bottom surface is a filter net with an aperture of about 3 mm, the front end opening is a sand receiving port or a sand inlet port, the rear end is closed, and a slot is provided at the lower end of the side wall of the sand collecting box), and ensure that the center of gravity of the sand collecting box passes through the center axis or axis of the rotating shaft; at the same time, the sand receiving port or the sand inlet port on the sand collecting box is located on the side where the balancing component is located, and the direction of the sand receiving port is parallel to the axial direction of the pointing rod.

[0023] When the wind blows and sand is collected at a certain angle to the tail, the windflow exerts pressure on the tail. Because the windward area at the other end of the pointing rod is smaller than that at the tail, the windward area is larger, resulting in unequal wind pressure. This wind pressure perpendicular to the tail generates a torque, which drives the rotating shaft and the sand collection box suspended at the bottom to rotate until the end of the pointing rod, equipped with the balancing component, faces the incoming wind. This drives the direction-finding mechanism to stabilize in a certain wind direction. Simultaneously, the sand collection box's sand collection opening faces the wind and collects dust. During the sand collection process, minor disturbances of sand and dust can be ignored in their impact on the sand collection box's center of gravity. In actual use, the torque balance at the center of the rotating shaft can be adjusted by adjusting the mounting position of the balancing component on the pointing rod. Within a predetermined time, the sand collection box is removed and the collected sand and dust is weighed to obtain the required sand collection data.

[0024] In some specific solutions, the sand collection box suspension structure 2 includes a box holder 22 and a sand collection box 21 for placing the sand collection box. The sand collection box 21 is provided with an opening for placing the sand collection box, and the shape of the sand collection box matches the sand collection box structure. The box holder 22 is fixed to the bottom end of the rotating shaft, and the sand collection box is fixed to the bottom of the box holder, and the center of gravity of the sand collection box passes through the central rotating shaft of the rotating shaft. At the same time, the opening on the sand collection box and the balance component are located on the same side of the rotating shaft, and the direction of the opening is parallel to the pointing rod. The sand collection box is provided with a slot for placing the sand collection box. When sand is collected, the sand collection box is placed in the sand collection box and fixed by the slot. To better match the sand collection box structure, in some solutions, the top surface of the sand collection box is a mesh structure with an open bottom.

[0025] In the preferred embodiment, see Figure 2 As shown, the driving direction-finding device also includes a rotating sleeve 16, which is provided with a pointing rod mounting hole and a rotating shaft mounting hole, and the axial direction of the pointing rod mounting hole is perpendicular to the axial direction of the rotating shaft mounting hole; the rotating sleeve is installed on the top of the rotating shaft 14 through the rotating shaft mounting hole, and two top screws 17 are provided between the inner wall of the rotating shaft mounting hole and the rotating shaft, the two top screws are located on both sides of the rotating shaft, and the two top screws pass a cross-sectional diameter of the rotating shaft, and at the same time, an arc-shaped groove is provided on the rotating shaft at the contact part with the top screw, one end of the top screw is placed in the arc-shaped groove and floats with the rotating shaft, and the other end is connected to the inner wall of the rotating shaft mounting hole by a thread; the pointing rod 11 is installed in the pointing rod mounting hole. In this solution, a rotating sleeve is provided at the top of the rotating shaft, and the top screws on both sides of the rotating shaft (the two top screws are 180° symmetrical and pass through the center of the circle) and the arc-shaped grooves on the rotating shaft float together to realize that the driving direction-finding device can be in a dynamic balance state in any direction of 360°; when the tail rotates to a certain position under the action of wind force, the power drives the rotating shaft to rotate in the circumferential direction through the top screws and the grooves, so as to realize the purpose of the 360° all-round sand collecting device to collect wind-blown sand and objects according to the wind direction; during the process, the 180° support point formed by the two top screws is the balance fulcrum of the wind vane (tail, pointing rod, and balancing component), which swings longitudinally around its axis in dynamic state, always keeping the wind vane in a balanced state; at the same time, the top screw is also the force transmission component for the wind vane to drive the rotating shaft to rotate; the top screw and the rotating shaft float together through the arc-shaped grooves to ensure that the pointing rod and the components at both ends of the rod and the rotating shaft will not produce circumferential displacement.

[0026] Example 2:

[0027] See also Figure 3 As shown, the wind and sand flux monitoring device of this embodiment includes a main support rod 41, which is vertically installed in the environment to be monitored. A plurality of support rods 42 are installed on the main support rod, and the plurality of support rods are sequentially distributed along the axial direction of the main support rod, as shown in FIG. Figure 3 As shown, they are distributed at equal intervals, and one end of each support rod is equipped with the sand mining device described in Example 1, which is specifically installed at the end of the support rod through a fixing plate 31. Figure 3 The sand collecting devices are located on the same axis. To automatically measure the weight of the collected sand and dust, a load cell is mounted on the end of each support rod. The corresponding sand collecting device is mounted on the load cell. The load cell measures the weight of the sand and dust in the sand collecting box in real time or at a fixed period, and transmits the weight to the data storage or data storage and display device 51 via wireless or wired means.

[0028] In some other solutions, in order to accurately obtain wind direction related data during sand mining, a wind direction sensor 61 is installed at the other end of each support pole, which transmits wind related data to the data storage or data storage and display device 51 in real time or periodically via wireless or wired means.
