Pond bottom sediment agitator

Abstract

The invention relates to a device of a pond culture machine, in particular to a mechanical device which can automatically move, run and work in a pond, i.e., a pond bottom sediment agitator, wherein a horizontal sliding plate (131) is arranged on the bottom of the pond bottom sediment agitator, an L-shaped cylindrical water barrel (132) is arranged above the horizontal sliding plate (131), stainless steel screens (135) used for preventing fish from entering are arranged at an upper opening and a lower opening respectively, a floating body assembly (138) is used for clamping the exterior of the water barrel (132), a sediment lifting device (134) is arranged inside a vertical tube of the water barrel (132), a submersible motor (134-g) is used for supplying driving power and transfers the power to an air floating output shaft (134-b) at the lower end part through an output shaft by a gear box and to a propeller (134-d) which is arranged relatively upwards through another output shaft which has another speed, and the air floating output shaft (134-b) is connected with a driving air floating generator (134-a). The pond bottom sediment agitator has a simple structure, is easy to manufacture and convenient to use, has a good bottom sediment agitating effect and an oxygen increasing effect, and enables the pond bottom sediment to give full play to the ecological functions without polluting the environment.

Description

[0001] technical field [0002] The invention relates to equipment and devices related to pond farming machinery, in particular to a mechanical device that can automatically move and work in ponds. Background technique [0003] In recent years, the scale of pond aquaculture in my country has been continuously expanding, and the output has increased significantly, but the relevant pond aquaculture machinery and equipment have not been updated in a timely manner. After the pond has been cultivated for several years, a large amount of organic matter such as residual bait and aquatic product feces deposited at the bottom of the pond will precipitate, and these sediments will mix with the sediment and other substances at the bottom of the pond to form bottom mud. A certain amount of bottom mud can provide fertilizer, keep fertilizer and regulate and buffer the water quality of ponds. However, a large amount of organic matter accumulates in the bottom mud. When these organic mat...

Problems solved by technology

[0006] The traditional mode of high-density breeding and large-scale fertilization and baiting leads to a large accumulation of residual bait and fish excrement in the water body, and the content of organic matter, nitrogen, and phosphorus in the water soars, seriously polluting the ecological environment of the pond

In the aging pond, the organic matter deposited for many years produces a large amount of toxic substances, which leads to the deterioration of the water quality, and the outbreak of various diseases in the breeding objects, which seriously affects the production and development of the breeding objects.
