Freshwater shrimp and crab pond feeding boat with spiral propelling device

Abstract

The invention discloses a freshwater shrimp and crab pond feeding boat with a spiral propelling device. The freshwater shrimp and crab pond feeding boat comprises a feeding boat body, a feeding mechanism, a driving mechanism, a control mechanism and a battery box, wherein the battery box is connected with the feeding mechanism, the driving mechanism and the control mechanism, the feeding mechanismis arranged on the middle upper surface of the feeding boat body, and the driving mechanism comprises a power source, a fixing support and a hollow cylinder. The power source is fixed onto the uppersurface of the tail of the feeding boat body, the hollow cylinder is mounted on the lower portion of the tail of the feeding boat body through the fixing support, the power source is connected with the hollow cylinder through a transmission mechanism and used for driving the hollow cylinder to rotate, the outer surface of the hollow cylinder is provided with continuously wound spiral blades, and the axis of the hollow cylinder is higher than a water surface. The feeding boat body can normally navigate in a pond overgrown with water plants, so that feeding operation of the shrimp and crab pondcan be realized. Besides, the freshwater shrimp and crab pond feeding boat is high in automation degree, and labor intensity is greatly relieved.

Description

technical field [0001] The invention relates to the technical field of feeding boats, in particular to a feeding boat for freshwater shrimp and crab ponds using a screw propulsion device. Background technique [0002] Freshwater shrimp and river crab are the main freshwater shrimp and crab breeding species in my country, which have high economic benefits. Because shrimp and crab move slowly, they are generally evenly distributed throughout the pond. Therefore, the feed needs to be evenly distributed throughout the pond when feeding. Due to the lack of special feeding equipment, manual rowing is generally used for feeding, which is labor intensive. At present, some enterprises and institutions have developed electric remote-controlled feeding boats powered by propellers for the feeding needs of the whole pond, which can reduce the labor intensity of feeding. However, since freshwater shrimp and river crab farming require a large amount of aquatic plants, most of the water ...

AI Technical Summary

Problems solved by technology

However, because the cultivation of freshwater shrimp and river crab requires a large amount of aquatic plants, most of the water surface in the pond is covered by aquatic plants, and it is easy for the propeller to be entangled by aquatic plants and cause failure.

Therefore, existing propeller power feeding boats cannot be applied to freshwater shrimp and river crab ponds
