Lotus root duckweed fishing device

Abstract

The invention belongs to the technical field of equipment for removing pollutants from water surfaces and particularly relates to a lotus root field duckweed fishing device. The lotus root field duckweed fishing device comprises a rack, a transmission belt and a water pump; the conveying belt and the water pump are both fixedly arranged on the rack; the conveying belt is provided with a bucket; arotating plate is hinged to the rack; a torsional spring is arranged at the hinged position of the rotating plate and the rack; a first switch and a second switch are further arranged on the rack; thebucket is used for pressing the rotating plate to rotate in an abutting manner; the rotating plate can press the first switch or the second switch in an abutting manner; a cylinder is further arranged on the rack; the output end of the cylinder is connected with a pushing plate which is provided with wheel teeth; a gear engaged with the pushing plate is further rotationally connected to the rack,and is provided with a collecting plate; a third switch is further arranged on the rack; a water sucking pipe is connected to the water pump; and a water wheel is rotationally connected with the inner wall of the water sucking pipe and is coaxially connected with negative pressure blades which are arranged below the collecting plate. By adopting the lotus root field duckweed fishing device, duckweed can be collected in a concentrated manner, and the lotus root field duckweed fishing device is mainly used for fishing of the duckweed in lotus root field.

Description

technical field [0001] The invention belongs to the technical field of equipment for removing pollutants from the water surface, and in particular relates to a fishing device for lotus root field duckweed. Background technique [0002] Lotus root fields are often covered with duckweed. If they are not salvaged in time, the water temperature in the field will be lowered, which will affect the germination and normal growth of lotus root buds. At present, farmers salvage duckweed manually, which is not only labor-intensive, but also the fishing efficiency is not ideal. [0003] For this reason, Chinese patent CN201520801323 discloses a kind of lotus field duckweed salvage boat, including hull, motor, driving wheel, driven wheel, suction pipe, horizontal bracket, vertical bracket, power supply, switch and surrounding the driving wheel and driven wheel. The track between them; the driven wheel is fixed on one side of the hull through a horizontal bracket; the motor is fixed abov...

Problems solved by technology

[0004] The above-mentioned patents can slowly gather duckweed and fish it into the hull through the wire mesh, which reduces the labor intensity of the cultivators, but there are still the following problems: when the wire mesh dumps the duckweed into the boat, the duckweed is sprinkled on the boat. All over the hull, when the duckweed in the hull is concentrated after being salvaged, it is necessary to manually sweep the duckweed together. The water adhering to the duckweed will make the duckweed adhere to the hull, which is inconvenient to clean
