Feed feeding device for large-area fishpond culture

Abstract

The invention relates to the technical field of fishpond cultivation, in particular to a large-area fishpond cultivation feed feeding device which comprises a feed box, a conveying structure, a throwing structure, a shielding structure, a sealing structure and a screening structure. The fodder throwing height can be increased through the conveying structure, the fodder throwing range can be expanded, the thrown fodder can be screened through the screening structure, and therefore the situation that caked fodder enters the device to affect normal throwing of the fodder is avoided, meanwhile, the good screening effect can be achieved on the fodder with different particle sizes, and the fodder throwing efficiency is improved. All-angle throwing of feed can be achieved through the throwing structure, the throwing area can be adjusted according to the size of a fishpond, so that the uniform feeding effect is achieved, the device can be protected in rainy days through the shielding structure, and it is avoided that rainwater enters the device to affect normal work of the device; the top side of the feed box can be sealed through the sealing structure, and meanwhile the feed box can be kept in an open state to facilitate feed adding.

Description

technical field [0001] The invention relates to the technical field of fish pond culture, in particular to a feed feeding device for large-area fish pond culture. Background technique [0002] Pond aquaculture refers to a production method that uses artificial excavation or natural ponds for aquatic economic animal and plant cultivation. out of complex system activities. Most of the pond culture adopts intensive and semi-intensive culture methods, with appropriate density polyculture, which fully exerts the production potential of bait, fertilizer and water body, and has a high degree of resource utilization. However, some marine ponds still carry out low-yield and low-efficiency extensive farming. Due to the long-term lack of renovation, some aquaculture ponds are getting old and the bottom of the pond is seriously silted, which affects the aquaculture production. The number of water changes in pond culture is small, the exchange with external water is limited, and the i...

Problems solved by technology

[0003] The throwing angle of the existing feed feeding machines for fish ponds is usually limited, so that when feeding larger ponds, it is often necessary to arrange more feeding devices, which increases the cost. At the same time, the throwing height of the feed is low, making the feed The throwing distance of the machine is relatively short, which l
