As shown in FIGS. 3 and 4, the vibration screening mechanism 9 includes a screening motor fixing plate 10 arranged on the bottom frame 3; the screening motor fixing plate 10 is arranged with a screening motor 11, a first rocker 12 is arranged on a protruding end of the screening motor 11, and a second rocker 13 is arranged on an end of the first rocker 12; a slider 14 is arranged on an end of the screening motor fixing plate 10, and a third rocker 15 is slidably arranged in the slider 14; an end of the third rocker 15 is connected to the second rocker 13, and the other end of the third rocker 15 is arranged with a roller 16; the end of the third rocker 15 defines a bar slot 90; as shown in FIG. 5, an end of the second rocker 13 is arranged with a short shaft 91, which passes through the bar slot 90; an end of the short shaft 91 is arranged with a limit block 92. If the bar slot and the short shaft are not provided, the second rocker may interfere with the movement of the third rocker, affecting the reciprocating movement of the third rocker. After the bar slot and the short shaft are provided, a certain degree of freedom can be obtained in the movement of the two rockers. A screening strainer 17 is arranged between the rollers 16 on both sides, and an arc track 18 is arranged on a side of the screening strainer 17; an upwardly curved guiding arc 181 is arranged on a front portion of the arc track 18, and the rollers 16 may cooperate with the arc track 18; a lower portion of the main body frame 1 is arranged with a swing assembly 19, and a lower end of the swing assembly 19 is connected to the screening strainer 17; an end of the screening strainer 17 is close to the plastic track 7, and a cross-section of the screening strainer 17 is of a multi-trapezoidal structure, which makes sediment and garbage in the screening surface block to a certain extent, and the sediment and garbage can completely fall into the ground, thereby enhancing the screening effect; an end of the main body frame 1 near a higher end of the plastic track 7 is arranged with a garbage bin 20; a top cover 30 is arranged on a top of the main body frame, and the top cover 30 is arranged with a photovoltaic panel for absorbing solar energy and converting it into electricity; the top cover is further arranged with an omnidirectional LIDAR 31 for scanning a surrounding environment and real-time feedback; as shown in FIGS. 1 and 2, a front end of the main body frame is arranged with a sixteen-lines LIDAR 32 to strengthen an image effect, and further arranged with an infrared binocular vision 33 to enhance an image effect at night and temperature measurement; a bottom end of the bottom frame is arranged with a water-quality detection sensor 34, which displays a state of water in real-time; a rear side of the main body frame is arranged with an anemometer 35, a warning light 36, and an interactive display 37, and the interactive display is capable of displaying various types of information for interaction. The vibration of the screening strainer is mainly realized through the cooperation of the arc track and the roller on the side of the strainer; the roller rolls back and forth along the arc track, and the screening strainer carries out a certain degree of lateral reciprocating movement; due to the curved structure of the track, the strainer will oscillate at the same time, and the sand will fall to the ground through the vibration of the screening strainer. Specifically, the roller reaches out forward in an initial position and hits the guiding arc, and a first screen vibration occurs at the time of the impact; the roller enters into a lower surface of the arc track, and the telescopic movement of the roller in the arc track drives the arc track to move up and down, which in turn drives the strainer to move up and down for swinging, thereby realizing the swinging screening of the strainer; then the roller retracts to leave the arc track, the arc track falls freely after losing the support of the roller, and a fall impact occurs at the lowest point of the fall, generating a second screen vibration; every two the impact vibrations will complete a strainer screening process; the roller is driven by a reciprocating mechanism to carry out the movement, such that the screening strainer can achieve continuous screening.

[0036] As shown in FIGS. 9 and 10, the screw propulsion mechanism 2 includes a propulsion motor 201 arranged on an upper portion of the main body frame 1, and an active sprocket 202 is arranged on a protruding end of the propulsion motor 201; a lower portion of the main body frame 1 is arranged with a main drive seat 203 and an auxiliary drive seat 204, and a screw propulsion cylinder 205 is arranged between the main drive seat 203 and the auxiliary drive seat 204; a follower sprocket 206 is arranged on an end of the screw propulsion cylinder 205, and the active sprocket 202 and the follower sprocket 206 are wound with a chain 207; the propulsion motor drives the screw propulsion cylinder to rotate through the chain transmission, thereby driving the whole device to move on the ground. The screw propulsion cylinder 205 includes a center shaft 208, and an end of the center shaft 208 is arranged with a support sleeve 209; the support sleeve 209 is arranged in the main drive seat 203 and the auxiliary drive seat 204; the center shaft 208 is arranged with a main cylinder 210, each of both sides of the main cylinder 210 is arranged with a welded cylinder 211, a side of the welding cylinder 211 is arranged with a welded end cap 212, and the welded end cap 212 is connected to the support sleeve 209. Compared with the traditional wheel movement, the proposed screw propulsion method is better adapted to soft ground such as sediment and is not easy to sink into the sediment. A side of the main drive seat 203 is arranged with a protective baffle 213, such that the chain will not be exposed to the air, providing protection to the chain.

[0037] As shown in FIG. 8, the garbage bin 20 includes a cabinet 27 arranged on the end of the main body frame 1; an outside of an inlet of the cabinet 27 is arranged with a feeding hopper 28, and the feeding hopper 28 faces the higher end of the plastic track 7; the feeding hopper is able to receive garbage in a better way, and an inlet thereof is arranged with a collection strainer for separating the large garbage from the small garbage. A stroke shovel 29 is arranged on a side of the cabinet 27 to make the upturned ground flat again.

[0038] In some embodiments, the garbage bin may be opened upward, with an opening aligned under an end of the plastic track; the garbage bin is symmetrically arranged with curved plates, as shown in FIG. 11. When the garbage is fed into the cabinet, the garbage is piled up in the middle and not piled up on both sides, which makes the garbage easily full. The curved plates are set up such that the garbage is deflected when fed into the cabinet, and the garbage is fed to both sides, such that the sides are even; further, a sensor is arranged at an inlet of the garbage bin; when the cabinet is full of garbage, the sensor sends a signal to the system.

[0039] The working principle of the present disclosure: the screw propulsion mechanism is started, and the propulsion motor will start; through the chain transmission, the screw propulsion cylinder will rotate, which makes the whole device move on the soft ground; an end of the screening strainer is inserted into the ground, and sediment with garbage will be brought into the screening surface; the screening motor is started, which makes the first rocker rotate and makes the third rocker move back and forth within the slide through the second rocker; the roller rolls back and forth along the arc track, the screening strainer vibrates, and the sediment falls from meshes of the strainer onto the ground; the garbage is sent to the plastic track; the power assembly is started, which makes the plastic track rotate, and the garbage enters into the garbage bin through the conveyance of the plastic track; through the sorting of the vibrating screening mechanism, the garbage and the sediment are effectively separated, such that the screening effect is improved.
