Multifunctional bait casting machine for Chinese mitten crab

Abstract

The invention discloses a multifunctional bait casting machine for Chinese mitten crabs. The machine comprises a housing. A bunker is arranged on the top inside the housing. The lower end of the bunker is connected with a discharging hopper. A vibration discharging device is arranged under the discharging hopper. A vibration bump is arranged under the vibration discharging device. A control device is arranged on the front surface of the housing. A solar panel and a storage battery are arranged on top of the housing. A temperature sensor and a refrigerator are arranged in the bunker. A distributor fixed on the bottom of the housing is arranged right below the vibration pump. Two double-impeller throwers are arranged on the left side and the right side of the distributor respectively. The left sidewall and the right sidewall of the housing, close to the bottom end of the housing, are equipped with two throwing openings that correspond to the double-impeller throwers in position. An oxygen charging pump, on the inner wall of the housing, is arranged over each throwing opening. Each oxygen charging pump is connected with an oxygen charging pipe. One end of each oxygen charging pipe is arranged near the corresponding throwing opening. The multifunctional bait casting machine has a simple structure, is convenient to operate, covers a wide bait casting area, and is high in work efficiency. Moreover, bait is sent to the bottom of a pond after passing through the throwing openings to be oxygenated, so the oxygenation effect is great and the bait can be evenly cast.

Description

technical field [0001] The invention relates to a feeding device, in particular to a multifunctional bait feeding machine for hairy crabs. Background technique [0002] We know that in the production process of pond aquaculture, the dissolved oxygen content on the water surface is high, while the dissolved oxygen content at the bottom of the pond is low. Under the condition of high-density farming, the aquaculture environment at the bottom of the pond is prone to hypoxia, which causes a large number of aquatic organisms to die. Therefore, increasing the dissolved oxygen content of the bottom water body has become a very important link in aquaculture production. [0003] At present, the commonly used feeder is to transport the bait to the throwing machine through the feeding device, and the bait is thrown to the pond by the throwing machine, which reduces the labor intensity of the workers. The existing feeder only has one on the shell opposite to the operation panel. The t...

Problems solved by technology

[0003] At present, the commonly used feeder is to transport the bait to the throwing machine through the feeding device, and the bait is thrown to the pond by the throwing machine, which reduces the labor intensity of the workers. The existing feeder only has one on the shell opposite to the operation panel. The thrower has low working efficiency, and the throwing area is small and the benefit is low

And if you breed in ponds, you will generally put a lot of bait in the bait feeder, but if you put a lot of bait in the silo in hot summer, it will definitely deteriorate due to high temperature, causing unnecessary waste
