Abstract

Provided is a copepoda harvesting device. The copepoda harvesting device is provided with a net tool and a water wheel 1. The net tool is a trap net. The action directions of blades on the water wheel point at an opening of the trap net. By utilizing the driving effect of the water wheel on water, the whole trap net moves on water flow, and copepoda enters the net tool along with the water flow and is harvested. Compared with the prior art, the copepoda harvesting device is mechanical, low in manpower consumption and high in harvesting efficiency.

Description

The copepoda recovering device
Technical field
The utility model relates to a kind of copepoda recovering device.
Background technology
Copepoda is used widely in aquaculture as fish hatching bait commonly used.In order to obtain enough copepoda, people often will carry out artificial breeding, utilize and discharge the Growth and Reproduction that nutriment promotes copepoda in the pond.When copepoda grows into applicable size, need to they be gathered with netting gear and render in the nursery pond.People manually gathered with diddle-net in the past, not only waste time and energy and also the utilization percent of gathering lower.
Summary of the invention
For above-mentioned deficiency, the utility model is exactly the copepoda recovering device that a kind of mechanization will be provided.
The copepoda recovering device that the utility model provides has netting gear, and said netting gear is to throw the net, and other has water wheels, and the force direction of the blade on the water wheels in water is to point to the mouth of throwing the net.
The copepoda recovering device that the utility model provides utilizes water wheels to the driving effect of water, by throwing the net pocket on current, makes copepoda enter netting gear with current and is gathered.Compared with prior art, the utility model provides a kind of copepoda recovering device of mechanization, and the manpower consumption is low, the efficient of gathering height.
Said water wheels are straight oar formulas, namely are to consist of by the rotating shaft of level with the plate blade of shaft parallel, and axial line is on the water surface during installation.Be that the paddling of blade in water on the water wheels only has a direction, because second half paddling process of blade is on the water surface.This water wheels can carry out under lower rotating speed the promotion of water, are conducive to protect copepoda and lower flow rate of water flow wash away so that the pond is produced.
Said throwing the net is flexibly connected the net capsule by dictyosome and forms in the bottom, with convenient transfer and transportation to the copepoda of gathering.
Description of drawings
Fig. 1 is the schematic diagram of the utility model one embodiment, among the figure: 1-water wheels, 2-pond, 3-stake, 4-dictyosome, 5-net capsule.
Embodiment
One copepoda recovering device as shown in Figure 1, is thrown the net, throw the net and formed by dictyosome 4 and net capsule 5, the network interface of dictyosome is fixed in the stake 3 that is installed in 2 ends of pond through gang rope, and the net bottom of dictyosome is movably connected the net capsule through rope, unties rope and can separate on net capsule and the dictyosome.On the water surface before the network interface water wheels 1 are installed, water wheels have the rotating shaft of a level, are fixed with Flat plate type blade in the rotating shaft, and blade pass is crossed the axis of rotating shaft.

Claims (3)

1. a copepoda recovering device has netting gear, it is characterized in that said netting gear is to throw the net, and other has water wheels, and the force direction of the blade on the water wheels in water is to point to the mouth of throwing the net.
2. copepoda recovering device as claimed in claim 1 is characterized in that said water wheels are straight oar formulas, namely is to consist of by the rotating shaft of level with the plate blade of shaft parallel, and axial line is on the water surface during installation.
3. copepoda recovering device as claimed in claim 1 or 2 is characterized in that said throwing the net is flexibly connected the net capsule by dictyosome and forms in the bottom.
