A suction pipe 4 is provided on the sand mining ship deck 1 along the swing arm 2, and one end of the suction pipe 4 is connected to a pump body provided on the sand mining ship deck 1, and a sand mining conical suction head 5 is provided on the end of the suction pipe 4 away from the sand mining ship deck 1. A mounting plate 6 is fixedly provided on the end of the swing arm 2, and the sand mining conical suction head 5 is fixedly connected to the mounting plate 6.

[0034] Furthermore, the swing arms 2 are provided with hydraulic cylinders or motors for driving the swing arms to swing relative to each other.

[0035] Furthermore, the computer is electrically connected to a data acquisition module, the angle sensor 3 is connected to the data acquisition module, and the computer communicates with the data acquisition module via the TCP / IP protocol to obtain the angle sensor 3 signal.

[0036] Specifically, the ship is controlled to move to the area to be mined, and the swing arm 2 is driven to swing by a motor or hydraulic cylinder. The swing arms rotate horizontally or vertically, so that the mounting plate 6 at the bottom of the swing arm 2 and the sand mining conical suction head 5 are placed on the upper side of the riverbed sand and gravel. The underwater situation is monitored by the camera 601 to avoid areas with a large number of oversized particles. Then, the swinging action of the swing arm 2 is controlled by the computer again, and the sand mining angle of the sand mining conical suction head 5 is adjusted to move the sand mining conical suction head 5 horizontally and vertically. At the same time, the swinging angle between the swing arms is collected by the angle sensor 3. The computer analyzes and processes the angle information collected by the angle sensor 3 through the data acquisition module, and analyzes and processes the deviations between the sand mining conical suction head 5 and the suction pipe 4 in the horizontal and vertical directions, thereby analyzing the force condition of the suction pipe 4 and the suction effect of the sand mining conical suction head 5.

The bottom of the ring-shaped housing 7 is provided with a ring-shaped groove 702 for the movement of the output shaft 802.

[0038] Further, the moving seat 8 is fixed with a sliding block 804, and the ring-shaped plate 701 is provided with a track groove 7012 for sliding of the sliding block 804.

[0039] Specifically, when the sand suction cone 5 sucks the riverbed sand and gravel, the drive motor 801 is controlled to operate, so that the output shaft 802 of the drive motor 801 drives the drive gear 803 to rotate, the drive gear 803 engages with the fixed rack 7011 fixed in the ring-shaped housing 7 to drive the moving seat 8 to rotate, and the moving seat 8 drives the sliding block 804 to slide in the track groove 7012 when moving, thereby improving the stability of the moving seat 8. When the output shaft 802 rotates, the breaking piece 9 rotates, so that the breaking piece 9 loosens and breaks the sand and gravel in the suction area of the sand suction cone 5, without frequent shifting of position to adjust the sand mining area. The broken riverbed sand and gravel meets the sand mining requirements, ensuring the sand mining effect and efficiency of the sand suction cone 5.

[0040] Referring to Figure 3 , Figure 4 , Figure 5 and Figure 6 , as a preferred technical solution of the present application, the breaking piece 9 includes a main rod body 901 obliquely arranged with the output shaft 802 and a plurality of breaking blades 902 equidistantly arranged on the main rod body 901.

[0041] Specifically, when the output shaft 802 drives the main rod body 901 to rotate, the main rod body 901 drives the breaking blades 902 connected thereto to rotate. Since the main rod body 901 is obliquely arranged with the output shaft 802, the main rod body 901 can loosen and break the sand and gravel in the suction area of the sand suction cone 5 in a large range when rotating around the output shaft 802, thereby ensuring the sand mining effect and efficiency of the sand suction cone 5.

[0043] Specifically, an annular groove 702 is provided to facilitate the smooth movement of the output shaft 802 in the annular shell 7 when the moving seat 8 moves. A rotatable annular baffle 10 is provided in the annular groove 702 to prevent the loosened and crushed sand and gravel of the crushing member 9 from entering the annular shell 7 through the annular groove 702. When the output shaft 802 moves, it drives the annular baffle 10 to move synchronously, thereby ensuring the normal operation of the crushing mechanism in the annular shell 7.

The end of the pull rope 121 away from the reel 12 passes through the annular shell 7 and the sand mining conical suction head 5 and is connected to an elastic filter screen 122. The elastic filter screen 122 is provided at the opening of the sand mining conical suction head 5.

[0045] Specifically, an elastic filter screen 122 is provided at the end of the sand mining conical suction head 5 for filtering large-sized gravel or impurities so that the specifications of the extracted sand and gravel are less than or equal to a fixed size. When the output shaft 802 drives the annular baffle 10 to rotate in the annular housing 7, the plurality of arc-shaped racks 1001 on the annular baffle 10 are alternately meshed with the driven gear 112. When the arc-shaped racks 1001 are meshed with the driven gear 112, the driven gear 112 drives the rotating rod 11 to rotate, and the reel 12 on the rotating rod 11 pulls the elastic filter screen 122 through the pull rope 121. When the driven gear 112 is pulled and is not engaged with the arc-shaped rack 1001, the rotating rod 11 is reset and rotated under the action of the torsion spring 111, and the reel 12 releases the wound pull rope 121 to reset the elastic filter screen 122. The elastic filter screen 122 is intermittently pulled by the pull rope 121 to make the elastic filter screen 122 shake, and the elastic filter screen 122 moves the intercepted sand and gravel with large particle size, so that the sand and gravel with large particle size move to the loose sand crushing mechanism, and then the sand and gravel are crushed and extracted, so as to improve the crushing effect of the sand and gravel and realize the continuous operation of the sand mining conical suction head 5.
