A double rope grab for removing aquatic plants

Abstract

The invention relates to the field of double-rope grab buckets, in particular to a double-rope grab bucket used for cleaning up aquatic plants. The double-rope grab bucket used for cleaning up the aquatic plants comprises an upper supporting beam, supporting ropes, brace rods, a lower supporting beam, six bucket valves, pulleys, an opening and closing belt and a weeding device, wherein the weeding device is located in the middle of the six bucket valves; in the working process, the opening and closing belt moves vertically to drive the bucket valves to open and close; the weeding device comprises a rotary shaft, sliding rods, rotary blades, a connection board, a motor and a gear shaft, and in the working process, the rotary shaft rotates to drive the rotary blades to rotate and cut off rootstocks of the aquatic plants; water leaking holes are formed in the lower portions of the bucket valves; triangular sawteeth are arranged on the two sides of each rotary blade. The cost of the double-rope grab bucket used for cleaning up the aquatic plants can be controlled; while the grab bucket grabs the aquatic plants, the rotary blades in the grab bucket can cut off and clean up the aquatic plants so as to facilitate subsequent grabbing, a large amount of water is not grabbed together with the aquatic plants, and therefore the grabbing pressure is relieved, and the double-rope grab bucket used for cleaning up the aquatic plants is wide in application range.

Description

technical field [0001] The invention relates to the field of double-rope grabs, in particular to a double-rope grab used for removing aquatic plants. Background technique [0002] At present, 283 alien species have been identified in my country. Among the 100 most threatening alien species in the world announced by the International Union for Conservation of Nature, my country has 50 species. It is one of the countries most seriously affected by the invasion of alien species in the world. [0003] Among them, there are 18 species of invasive aquatic plants in my country, such as water hyacinth and Spartina alterniflora, etc.; 170 species of invasive terrestrial plants, such as Eupatorium adenophorum and ragweed; serious harm caused by genetic resources and so on. [0004] In aquatic plants, such as water hyacinth, in the suitable growth area, they often overgrow and seize the water surface, affecting shipping, suffocating fish, and endangering health; these aquatic plants ha...
