The slide plate 10 is slidably connected to the two horizontal guide rods 9. The two horizontal guide rods 9 guide the slide plate 10 together, which can make the slide plate 10 more stable when moving. The horizontal guide rods 9 are sleeved with the first spring 11. The two ends of the first spring 11 are respectively connected to the horizontal guide rod 9 and the slide plate 10. The first spring 11 is sleeved on the horizontal guide rod 9 to prevent the first spring 11 from bending. The right side of the slide plate 10 is connected with the push plate 12 by bolts. The front and rear sides of the left side of the top of the mounting plate 4 are connected with A vertical guide rod 13, two vertical guide rods 13 are slidably connected with a first baffle 14, the two vertical guide rods 13 jointly guide the first baffle 14, which can make the first baffle 14 more stable when moving, a second spring 15 is sleeved on the vertical guide rod 13, the two ends of the second spring 15 are respectively connected to the vertical guide rod 13 and the first baffle 14, the second spring 15 is sleeved on the vertical guide rod 13, which can prevent the second spring 15 from tilting, the front and rear sides of the top of the salvage net 7 are connected with inclined plates 16, the front and rear sides of the right side of the first baffle 14 are provided with notches 17, the inclined plate 16 will pass through the notch 17 during the upward movement, the front and rear sides of the right side of the first baffle 14 are provided with contact parts 18, and the right side of the first baffle 14 is an inclined surface 19.

[0037] like Figure 6 As shown, a blocking mechanism is also included, which includes a blocking net 20 and a roller 21. The blocking net 20 is hinged on the left side of the bottom of the salvage net 7, and the roller 21 is rotatably connected to the left side of the blocking net 20.

[0038] like Figure 3 As shown, a brush 48 is also included. The right side of the salvage net 7 is connected with the brush 48, and the brush 48 is in contact with the trash-blocking net 2.

[0039] Initially, the first baffle plate 14 blocks the push plate 12, and the first spring 11 is in a stretched state; the pre-buried ditch 1 is installed in the farmland ditch, and the water in the farmland ditch will flow into the pre-buried ditch 1. The garbage blocking net 2 can block the garbage in the pre-buried ditch 1 to prevent the garbage from floating into the farmland. The garbage will remain on the salvage net 7. After the salvage net 7 is loaded with a proper amount of garbage, the screw motor 6 is controlled to drive the salvage net 7 and the inclined plate 16 to move upward. The salvage net 7 salvages the garbage upward, and the inclined plate 16 will pass through the gap 17 to prevent the inclined plate 16 from colliding with the first baffle plate 14. The salvage net 7 will collide with the first baffle plate 14 during the upward movement. The contact portion 18 contacts and pushes the first baffle plate 14 to move upward, and the second spring 15 is stretched. When the first baffle plate 14 no longer blocks the push plate 12, under the action of the first spring 11, the push plate 12 moves to the right, and pushes the garbage picked up by the salvage net 7 into the collection box 8 for collection. The garbage is automatically cleaned and collected, which is safer and can improve work efficiency. The upward movement of the salvage net 7 will drive the brush 48 to move upward. The brush 48 can clean the silt on the dirt-blocking net 2 to prevent the silt from blocking the dirt-blocking net 2. The upward movement of the salvage net 7 can also drive the blocking net 20 to rotate upward, and the blocking net 2 0 can block the garbage in the pre-buried ditch 1 to prevent the garbage from floating under the salvage net 7 and causing the salvage net 7 to be unable to reset downward. When the blocking net 20 rotates upward, the roller 21 will roll at the bottom of the pre-buried ditch 1 to prevent the blocking net 20 from rubbing against the pre-buried ditch 1. Then the screw motor 6 is controlled to drive the salvage net 7 and the inclined plate 16 to move downward, and the contact portion 18 of the salvage net 7 and the first baffle 14 is disengaged. Under the action of the second spring 15, the first baffle 14 moves downward and resets, and the inclined plate 16 pushes the push plate 12 to move leftward, and the push plate 12 drives the slide plate 10 to move leftward. The first spring 11 is stretched, and the push plate When 12 moves to the left and contacts the inclined surface 19 on the right side of the first baffle plate 14, the pushing plate 12 will push the first baffle plate 14 to move upward, and the second spring 15 is stretched. After the pushing plate 12 passes over the first baffle plate 14, under the action of the second spring 15, the first baffle plate 14 moves downward and resets, and the left side of the first baffle plate 14 contacts the pushing plate 12, so that the first baffle plate 14 can block the pushing plate 12. The upward movement of the salvage net 7 can also drive the blocking net 20 to rotate downward. The blocking net 20 no longer blocks the garbage in the pre-buried ditch 1, and the garbage will float onto the salvage net 7. Repeat the above operations to continue to clean and collect the garbage.
