A kind of pond bottom cleaning machine and cleaning method for Chinese shrimp seedlings

Abstract

The invention discloses a pool bottom cleaning machine for prawn seedlings in China. A cleaning mechanism and a sludge crushing mechanism are arranged at the bottom of the cleaning ship plate. The cleaning mechanism includes a gear mounting case, a side wall of the gear mounting case and a cleaning ship plate. The side walls of the front ends are hinged, and an underwater motor is installed on the side wall of the gear installation cover close to the cleaning ship plate. The output end of the underwater motor is sleeved with a driving gear. The second driven gear is engaged with the driven gear on the top of the cleaning ship plate. The bottom of the cleaning ship plate is located on the left side of the underwater motor. The cleaning drum and the dirty box are respectively installed through the lifting mechanism, and the rotating end of the middle part of the driving gear is socketed. There is a connecting rotating rod, and the outer walls of the front and rear sides of the connecting rotating rod are sleeved with first rotating sheaves. The device of the present invention drives the crushing rotating rod and the spiral stirring blades to rotate and stir, and twist the large pieces of sludge on the front side of the cleaning drum. It is more convenient to transfer the sludge into the dirt box through the dirt removal plate.

Description

technical field [0001] The invention relates to the field of prawn seedlings, in particular to a pool bottom cleaning machine and a cleaning method for raising prawn seedlings in China. Background technique [0002] Prawns, scientific name Oriental prawns, also known as Chinese prawns and tiger prawns. Arthropoda, Mollusca, Decapod, Shrimpidae, Penaeus. The prawns are large, commonly known as prawns. The females of prawns are generally 16-22 cm in length and weigh 50-80 grams. The largest can reach 30 cm and weigh 250 grams; the males are smaller, with a body length of 13-18 cm. , weighing 30-50 grams. Prawns are wide-temperature and wide-halt marine animals. The body of Penaeus Mangniu Island is long and cylindrical, with flat left and right sides. The body is divided into head, thorax and abdomen. It consists of 20 segments. The abdomen is long, muscular, and clearly segmented. [0003] At present, in small-scale high-density aquaculture, due to the large-scale product...

AI Technical Summary

Problems solved by technology

[0005] During the breeding process of prawn seedlings, the water quality requirements are very high, and the breeding pond needs to be cleaned regularly. The existing bottom cleaning machine for prawn seedling breeding has shortcomings. It is easy to cause blockage of the sewage pumping pipe, and it is not convenient to continue to clean the bottom of the pool. When there is a large mud block inside the bottom of the pool, it cannot be stirred and crushed, and it is not convenient to carry and clean it.
