Problems solved by technology

[0002] In fish farming, the high incidence of duckweed on the water surface will reduce the dissolved oxygen in the water and block sunlight, resulting in the inability of underwater plants to perform photosynthesis, further eutrophication of the water body, and serious death of fish due to hypoxia

Embodiment 1

[0020] Such as Figure 1~2 A schematic diagram of the structure of the duckweed salvage ship is shown, figure 1 Shown is the state in which the salvage shovel 3 collects the duckweed on the water surface into the salvage shovel 3 when the salvage ship is moving. A storage bin 2 is arranged on the hull 1, and the salvage mechanism provided at the bow includes a salvage shovel 3, the shape of the salvage shovel 3 is similar to the bucket of a forklift, and the opening of the salvage shovel 3 faces the direction of the hull, so that when the ship moves Just can collect the duckweed in the hull 1 front in the bucket. After enough duckweed is collected, the duckweed of the salvage shovel 3 is poured into the storage bin 2 . One end of the support rod 4 is affixed to the back of the fishing shovel 3, and the other end of the support rod 4 is hinged on the hull 1, so that the fishing shovel 3 can rotate around the hinge point. A slide block 5 is set to be slidably connected to the...

Embodiment 2

[0024] On the basis of the above embodiments, considering that a large amount of duckweed is collected in the salvage shovel 3, even if most of the duckweed can be poured into the storage bin, some duckweed will be attached to the salvage shovel 3 and it is not easy drop. This embodiment has perfected the structure of salvage shovel 3, as Figure 5 , Image 6 As shown, a flushing device is also provided at the front of the fishing shovel 3, and two circular rotating shafts 33 are arranged on the two side plates 31; The rotating part 340 connected by rotation, the main structure of the turning plate 34 is a thin plate-shaped water retaining plate 341 , and the turning plate 34 is connected with the turning part 340 . Such as Image 6 As shown, the water baffle 341 leans against the bottom of the shovel 30 to form a triangular cavity. When the salvage shovel 3 just leaves the water surface, the water has no time to flow out and is stored in the cavity. As the rotation angle b...

Embodiment 3

[0026] In another embodiment, such as Figure 5 , Image 6 As shown, by setting a water tank 35 on the bottom of the shovel 30, it can also play a role in scouring the duckweed. The principle is that during the rotation of the salvage shovel 3 , the water originally existing in the water tank 35 flows out because of the inclination, which can wash away the duckweed, thereby washing down the duckweed attached to the shovel wall.

Abstract

The invention discloses a lemna minor salvage ship. The ship comprises a storage chamber, a salvage device, a slide block, a supporting rod, a pushing rod and a stepping motor, and the storage chamberis formed in a ship body; the salvage device is located at the prow position and comprises a salvage shovel, the salvage shovel is in a scraper pan shape, and the facing direction of an opening of the salvage shovel is consistent with the running direction of the salvage ship; the back portion of the salvage shovel is fixedly connected to one end of the supporting rod, and the other end of the supporting rod is hinged with the ship body; the slide block is slidably connected with the supporting rod, one end of the pushing rod is hinged with the slide block, the other end of the pushing rod isconnected with the stepping motor, and the stepping motor is fixed to the ship body.

Description

Technical field: [0001] The invention relates to duckweed cleaning, in particular to a duckweed salvage ship. Background technique: [0002] In fish farming, the high incidence of duckweed on the water surface will reduce the dissolved oxygen in the water and block sunlight, resulting in the inability of underwater plants to perform photosynthesis, further eutrophication of the water body, and serious death of fish due to hypoxia. Invention content: [0003] Aiming at the fishery damage caused by the high incidence of duckweed, the invention provides a duckweed salvage ship capable of efficiently cleaning duckweed. [0004] The technical solution is that a duckweed salvage ship includes a storage bin and a salvage device, the storage bin is arranged on the hull; the salvage device is located at the bow and includes a salvage shovel, the salvage shovel is in the shape of a bucket, and the The opening direction of the salvage shovel is consistent with the direction of trave...
