Description

Fish suction pump fish collection device for net cage

technical field

The invention belongs to the technical field of machinery, and relates to a fish-absorbing pump fish-collecting device used in net cages.

Background technique

At present, in aquaculture, especially in large-scale aquaculture ponds and large-scale deep-water cage base aquaculture, due to the increasing scale of aquaculture, the output of farmed fish is also increasing. Currently, a single large-scale deep-water cage can be aquaculture 10 to 50 tons of finished live fish, so when the fish grows large, the live fish must be caught and sold in a timely manner to ensure the economic benefits of farming, but such a large number of finished live fish must be caught and maintain a high survival rate , because there is no suitable fast and efficient mechanized fish harvesting equipment, catching fish is a big problem. At present, only manual fish harvesting, or crane-type equipment and hanging baskets are used to collect fish. The fish speed is slow for a long time, and the mechanical damage to the fish is also great, resulting in high mortality of live fish, which will seriously affect the economic benefits of farming. Therefore, how to quickly and efficiently mechanize fish harvesting is an urgent task in the current large-scale aquaculture industry. problem to be solved.

Fish suction pumps, especially vacuum fish suction pumps, are used to suck fish from cages or fish holding containers and then transfer them to other places. The working principle of vacuum fish suction pumps is to vacuumize a tank first. Open the valve of the fish inlet port after a certain vacuum degree, the fish-water mixture is sucked into the tank from the fish inlet pipe, close the valve of the fish inlet port after suction, and then transport the fish in the tank to the cabin through pumps and other equipment wait.

But, because net cage is bigger, and fish suction pipe can not be too big again, the fish in net cage can run around, and this is unfavorable for that fish is sucked into tank body, and the efficiency of sucking fish is low.

In the above-mentioned fish-suction pump fish-collecting device for net cages, the fixed seat is connected to the rotating shaft of the second motor, and the fixed seat can rotate coaxially around the rotating shaft of the second motor relative to the gear. Since the number of teeth of the gear is obviously less than the number of teeth of the ring gear on the upper edge of the cage, when the gear circles along the ring gear at the upper end of the cage, the number of rotations is relatively large, so the fixed seat and the gear are set to be non-fixed. The structure can reduce the linkage between the connecting rod and the gear, and improve the stability of use.

Compared with the prior art, the present invention has the following advantages:

1. The fish suction pipe port of the fish suction pump extends into the water in the middle of the spiral body. The uppermost end of the spiral body is connected to the motor one, and the motor one drives the spiral body to rotate. The rotation of the spiral body will drive the fish to gather in the middle of the spiral cylinder, which is beneficial to the suction of the fish suction pump. Fish, improve the efficiency of sucking fish.

2. In the spiral channel formed by the spiral body, a mesh block body perpendicular to the cylinder wall is set. When the spiral body rotates, it can prevent fish from running in the opposite direction to the spiral body rotation, further improving the fish suction efficiency.
