Description

Technical Field

[0001] This utility model relates to the field of river crab farming technology, and in particular to a feed feeding device for river crab farming. Background Technology

[0002] In the process of large-scale crab farming, feed feeding is a key factor affecting the growth rate, survival rate and farming efficiency of crabs. Scientific feeding methods need to take into account the uniformity, timeliness and suitability of feed distribution to meet the feeding needs of crabs at different growth stages, while reducing feed waste and water pollution. As the aquaculture industry develops towards intensification and intelligence, it promotes the standardization and efficiency of the crab farming industry.

[0003] In existing technologies, the direction of feed placement is fixed, which cannot achieve multi-directional coverage and expansion of the placement range. As a result, feed can only be distributed in local areas of the aquaculture waters, and crabs in most areas have difficulty obtaining food, which in turn affects the uniformity of crab growth. Utility Model Content

[0004] Given that the existing feed distribution direction is fixed, it is impossible to achieve multi-directional coverage and expand the distribution range, resulting in feed being distributed only in local areas of the aquaculture waters, and crabs in most areas having difficulty obtaining food, thus affecting the uniformity of crab growth, this utility model is proposed.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a feeding device for crab farming, comprising a storage structure, a feeding structure, and a stirring structure. The feeding structure and the stirring structure are respectively installed on the storage structure. The feeding structure includes a feeding pipe, a connecting sleeve, a first motor, a second motor, and a third motor. A first gear is fixedly installed on the connecting sleeve, and a second gear is fixedly installed on the motor shaft of the first motor. The second gear and the first gear mesh with each other. A spiral feeding auger is rotatably arranged inside the feeding pipe. The motor shaft of the second motor is fixedly connected to the spiral feeding auger. A discharge pipe is fixedly arranged at the end of the feeding pipe away from the second motor. A guide plate is installed on the discharge pipe through a fixed frame. The motor shaft of the third motor is fixedly connected to a connecting shaft on the guide plate.

[0006] As a preferred embodiment of the crab farming feed feeding device of this utility model, the storage structure includes a storage box and a support frame. The storage box is fixedly installed on the support frame, a top cover is provided at the top of the storage box, and a discharge pipe is fixedly provided at the bottom of the storage box.

[0007] In a preferred embodiment of the crab farming feed feeding device of this utility model, the feed conveying pipe is rotatably mounted on the discharge pipe through a connecting sleeve, and the discharge pipe, the connecting sleeve and the feed conveying pipe are internally connected.

[0008] In a preferred embodiment of the crab farming feed feeding device of this utility model, the first motor is fixedly mounted on the storage box via a frame, and the second motor is fixedly mounted on the side wall of the feed pipe.

[0009] As a preferred embodiment of the crab farming feed feeding device of this utility model, the fixed frame is symmetrically fixed on both sides of the discharge pipe, the guide plate is rotatably disposed between the fixed frames through a connecting shaft, the guide plate is directly below the discharge pipe, and the third motor is fixedly installed on the outside of the fixed frame.

[0010] As a preferred embodiment of the crab farming feed feeding device of this utility model, the stirring structure includes a rotating shaft and a fourth motor. The rotating shaft is rotatably mounted on the top cover, and stirring blades are fixedly installed on the rotating shaft. Spiral blades are provided on the rotating shaft and at the bottom of the stirring blades. The fourth motor is fixedly installed on the top of the top cover, and the motor shaft of the fourth motor is fixedly connected to the rotating shaft.

[0011] The beneficial effects of this utility model are:

[0012] 1. The first motor drives the feed pipe to swing back and forth, achieving uniform feeding in multiple directions. Then, the third motor drives the guide plate to swing back and forth, ensuring that the feed covers a wider area of ​​water, avoiding the feed from being concentrated in a small area, effectively improving the feed utilization rate, thereby expanding the distribution range of crabs in the water, and preventing crabs from gathering in specific areas due to feed shortage, thus improving the aquaculture efficiency.

[0013] 2. The stirring blades thoroughly agitate the feed in the storage tank, effectively preventing the feed from clumping due to moisture or compression. The spiral blades simultaneously and continuously transport the loosened feed to the discharge pipe, avoiding blockages around the discharge pipe, ensuring the looseness and smooth transport of the feed, improving feed utilization, and ensuring stable and efficient feeding operation.
