Abstract
桡足类采收装置，有网具，所说网具是张网，另有一个水轮1，水轮上的叶片在水中的作用力方向是指向张网口的。本实用新型提供的桡足类采收装置，利用水轮对水的驱动作用，由张网兜在水流上，使桡足类随水流进入网具而被采收。与现有技术相比，本实用新型提供了一种机械化的桡足类采收装置，人力消耗低、采收效率高。
The copepod harvesting device has net gear, and said net gear is a stretch net, and there is another water wheel 1, and the active force direction of the blade on the water wheel points to the net mouth. The copepod harvesting device provided by the utility model utilizes the driving effect of the water wheel on the water, and the copepods enter the net with the water flow and are harvested by a net pocket on the water flow. Compared with the prior art, the utility model provides a mechanized copepod harvesting device with low manpower consumption and high harvesting efficiency.
Description
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.
