Description

Raft type grass planting device

Technical Field

The invention relates to the field of aquatic weed fishing machinery, in particular to a raft type grass planting device.

Background

In a pond with good water quality, the aquatic weeds also grow very flourishing, and a proper amount of the aquatic weeds is beneficial to aquaculture.

First, aquatic weeds are also a major source of aquatic animal feed. The fresh and tender aquatic weed is rich in nutrition and has no pollution. Aquatic plants are rich in nutrients such as vitamins and proteins, which are essential nutrients for aquatic animals. Is much better than artificial bait, is more beneficial to the growth of aquatic animals, and is purely natural and pollution-free. They also provide a good place for survival.

Secondly, a habitat can be provided for part of the aquatic animals. Some animals have weak force in molting or other growth periods and are easily attacked by other animals, and in this time, the aquatic weeds can provide a hidden place for the animals to avoid the attack, avoid the injury and improve the survival rate, so that the aquaculture benefit is improved.

And thirdly, the aquatic weeds can absorb a large amount of harmful gases, such as residual baits and aquatic animal excrement, and release some harmful gases when decomposed, so that the substances can generate great harm to the growth of the aquatic animals, and the aquatic weeds can just promote the decomposition of the substances, so that the aquatic weeds have a good effect on purifying water bodies, and the transparency of the water bodies can be improved.

Finally, some aquatic weeds have the functions of preventing and treating diseases, and after the aquatic animals eat the aquatic animals, the aquatic animals can prevent and treat diseases, sterilize, diminish inflammation and detoxify. Reducing the morbidity of the whole pond. However, the amount of the aquatic weeds is limited and cannot be flourishing.

However, in deep water areas, aquatic plants cannot absorb energy and cannot grow because of no sunlight irradiation. At present, a waterweed planting device which can plant waterweeds in deep water areas and can adjust and control the planting area and the quantity of the waterweeds is lacked.

Disclosure of Invention

Preferably, the support frame includes a bracing piece and a plurality of fixed rope, the rope is connected the bracing piece, fixed rope connect in between bracing piece and the ground.

Preferably, the support bar is fixed to a body of water near or on the shore, and the line is floated on the surface of the body of water by the float.

Preferably, the grass planting raft comprises a plurality of the raft type grass planting units, and the raft type grass planting units are arranged in parallel at intervals.

Preferably, the straw planting device further comprises a protective net, wherein the protective net surrounds the periphery of the raft type grass planting units.

Preferably, the protective net is a 20-mesh purse net.

Due to the adoption of the technical scheme, the invention has the following beneficial effects:

1. the raft type grass planting device can form a water grass area with a certain area, purify water quality, and enable planting area and water grass quantity to be adjustable and controllable, and cannot cause adverse effects on water bodies.

2. Due to sunlight, wind waves and the like, aquatic plants cannot grow in deep water areas. The raft type grass planting device can plant aquatic weeds in deep water areas, so that the water body is improved.

3. The aquatic weeds can be planted in the area in a large area, and after the aquatic weeds grow vigorously, the counterweight balls can be added, so that the roots of the aquatic weeds are kept in the area below the water surface, and the aquatic weeds are prevented from floating, moving or being scraped.

4. The raft type grass planting device disclosed by the invention is convenient and quick to plant aquatic weeds, low in cost and high in efficiency, the growth condition of the aquatic weeds can be checked at any time, and the aquatic weeds with poor growth can be replanted and pruned at any time.

fig. 2 is a schematic structural view of a raft grass planting device according to an embodiment of the present invention.

Detailed Description

The following description of the preferred embodiments of the present invention, with reference to the accompanying

drawings

1 and 2, will provide a better understanding of the function and features of the invention.

Referring to fig. 1 and 2, a raft grass planting device according to an embodiment of the present invention includes raft grass planting units 1, each raft grass planting unit 1 includes two support frames 11, a rope 12, a plurality of floats 13, and a plurality of baskets 14; the rope 12 is connected between the two support frames 11; the floaters 13 are distributed at intervals and fixed on the rope 12; a basket 14 is hung from the lower end of the float 13 through a connecting rope 15.

The basket 14 is provided at the bottom thereof with a weight body. The counterweight body adopts a plurality of counterweight balls.

Submerged plants are planted in the basket 14.

The basket 14 is at a distance of 1.5m or nearly 1.5m from the float 13 when the connecting string 15 is straightened.

The support frame 11 comprises a support rod 111 and a plurality of fixing ropes 112, the ropes 12 are connected with the support rod 111, and the fixing ropes 112 are connected between the support rod 111 and the ground.
