DETAILED DESCRIPTION

[0016] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0017] Example

[0018] like Figure 1 , Figure 2 and Figure 3 As shown, the lotus root excavator suitable for deep-water lotus roots provided in this embodiment includes a frame 1, square water tanks 2 are symmetrically installed on both sides of the front end of the frame 1, and a horizontal column water tank 3 is installed at the center of the bottom of the rear end of the frame 1; the bottom surfaces of the square water tank 2 and the column water tank 3 are flush, and the square water tank 2 and the column water tank 3 serve as buoys, which can make the frame 1 float on the water surface, and water can be injected into the square water tank 2 and the column water tank 3, so as to control the floating height of the frame 1 and increase the floating stability;

[0019] A driving motor 4 and a centrifugal pump 5 are fixedly mounted on the frame 1 above the column water tank 3. A water inlet pipe 6 is connected to the water inlet of the centrifugal pump 5. In this embodiment, the water inlet pipe 6 is L-shaped, located in the middle of the rear side of the column water tank 3, and the bottom end of the water inlet pipe 6 is lower than the square water tank 2 or the bottom surface of the column water tank 3, so as to ensure that the bottom end of the water inlet pipe 6 is always in the water, so that the impeller of the centrifugal pump 5 rotates, and negative pressure can be generated to draw water into the centrifugal pump 5 through the water inlet pipe 6. After the water enters the centrifugal pump 5, it is pressurized under the rotation of the impeller of the centrifugal pump 5, and then sent to the centrifugal pump 5. into the water delivery pipe 7; one end of the water delivery pipe 7 away from the centrifugal pump 5 is connected to a plurality of water spray heads 9 through a shunt pipe 8; the pressurized water passes through the water delivery pipe 7 and the shunt pipe 8, and is sprayed out from the water spray heads 9 at high pressure; a plurality of the water spray heads 9 are evenly installed on the frame 1 between the two square water tanks 2, and a plurality of the water spray heads 9 are located in the lower half of the frame 1. When the frame 1 moves to the vicinity of the lotus root, the high-pressure water flow sprayed by the water spray heads 9 will disperse the silt attached to the lotus root. Due to the hollow structure of the lotus root, the lotus root floats to the water surface under the action of buoyancy after being separated from the silt;

[0020] A support frame 10 is installed in the middle of the top surface of the frame 1, and a material receiving box 11 is installed in the support frame 10. A fixed frame 12 is symmetrically installed between the top ends of both sides of the front part of the support frame 10 and the front ends of both sides of the frame 1. Rotating rollers 13 are respectively installed at both ends of the fixed frame 12, and chain plates 14 matching with them are set on the two rotating rollers 13. Several salvage plates 15 are evenly installed on the chain plates 14. The driving end of the driving motor 4 and one end of the rotating roller 13 close to the material receiving box 11 are fixedly connected with a synchronous wheel 16, and a synchronous belt 17 is installed between the two synchronous wheels 16; that is, the driving motor 4 works to drive the rotating roller 13 to rotate, so that the chain plate 14 drives the salvage plate 15 to move, so that the salvage plate 15 will pick up the lotus roots floating on the water surface, and by controlling the distance between adjacent salvage plates 15, the salvaged lotus roots are straightened and aligned, and then transported to the top of the material receiving box 11 through the chain plate 14 and poured into the material receiving box 11;

[0021] Vertically arranged electric propellers 18 are symmetrically installed on both sides of the rear end of the frame 1, and the electric propellers 18 are connected to a controller. The electric propellers 18 have built-in brushless three-phase motors, and the two brushless three-phase motors are respectively connected to the controller through bidirectional brushless electric regulators; the controller adopts a differential mixed air mode to control the propellers, and its movement principle is: if the two electric propellers 18 are controlled to rotate forward or reverse at the same time, the frame 1 can move forward or backward; if the two electric propellers 18 are controlled to turn in opposite directions, the frame 1 can turn left or right; that is, the electric propellers 18 are controlled by the controller, so that the frame 1 drives the entire device to achieve flexible self-propelled movement.

[0022] The above is only a preferred implementation of the present invention, but the protection scope of the present invention is not limited thereto. Any modification and replacement based on the technical solution and utility model concept provided by the present invention should be included in the protection scope of the present invention.
