Problems solved by technology
[0003] When cleaning the sludge, the cultured animals are usually transferred first, and then the sludge is treated with the sewage suction device after the water is drained. However, the existing sewage suction device cannot directly carry out sewage suction treatment when encountering relatively thick sludge. If you suck it directly, the pipe will be blocked. In order to solve this problem, the sludge is usually pulverized in advance and then sucked. However, because the blade rotates in a circular shape during pulverization, the dirt cannot be completely cleaned at the corners. The mud is crushed, resulting in incomplete suction

The invention discloses an aquaculture pond bottom sewage suction device, comprising a sludge crushing box, a motor one is arranged at the center of the inner top surface, and two partitions located on both sides of the motor one are arranged inside the first motor. The shaft is connected with a shaft 1, the other end of the shaft 1 is provided with a bevel gear 1, a shaft 2 is arranged below the shaft 1, the shaft 2 is rotatably connected with the two partitions, the two ends of the shaft 2 are fixed with cylindrical cams, and the shaft 2 is provided with There is a bevel gear 2 meshing with the bevel gear 1, and cam connecting rods are clamped in the cam grooves of the two cylindrical cams. The other end of each cam link extends to the bottom of the sludge crushing box, and a connecting block is fixed. The two connecting blocks are provided with a plurality of cutting blades for cutting sludge, and two sides of the bottom of the crushing box are provided with cutting blades Two of the plurality of cutting blades in a staggered arrangement. The invention can clean the sludge at the corners and clean more thoroughly.
Description
technical field [0001] The invention relates to the technical field of aquaculture, in particular to a sewage suction device at the bottom of an aquaculture pond. Background technique [0002] In high-density aquaculture, there is a large amount of sludge at the bottom of the pond, which is composed of residual bait, feces, biological corpses, pathogenic bacteria and virus particles. These sludges are nitrogen-containing organic substances, which are decomposed into ammonia nitrogen, nitrite nitrogen, hydrogen sulfide and other substances that are extremely harmful to fish and shrimp under the action of bacteria, and are also breeding grounds for bacteria and viruses. It is very important work in the production of density farming. [0003] When cleaning the sludge, the culture is usually transferred first, and then the sludge is treated with a sewage suction device after draining the water. However, the existing sewage suction device cannot directly perform sewage suction t...
