Seaweed seed sowing device

Abstract

The invention discloses a seaweed seed sowing device, and relates to the technical field of sowing devices. The seaweed seed sowing device comprises a cart assembly and a sowing system; the cart assembly comprises a cart, a ditching device and a soil covering device, and the ditching device and the soil covering device are arranged on the cart; the sowing system is arranged on the cart and comprises a frame body, a driving assembly and two sowing assemblies symmetrically arranged at the two sides of the frame body, and each sowing assembly comprises a seed taking and discharging pipe, a watertank and a slider-crank mechanism, wherein the water tank is arranged on the frame body, the slider-crank mechanism comprises a slider slidably arranged on the frame body, the seed taking and discharging pipe is fixedly connected with the slider, a seed taking opening is formed in the side wall of the seed taking and discharging pipe, a water inlet is formed in the bottom end of the water tank, the seed taking and discharging pipe and the water inlet are oppositely arranged, and the size of the water inlet is smaller than that of seeds and larger than or equal to that of the seed taking and discharging pipe; and the driving assembly is in transmission connection with the two slider-crank mechanisms. The seaweed seed sowing device is simple to operate, low in cost, high in efficiency and beneficial to seed germination.

Description

technical field [0001] The invention relates to the technical field of sowing devices, in particular to a seaweed seed sowing device. Background technique [0002] Seagrass is the only monocotyledonous angiosperm known on the earth that can live completely in seawater, and the seagrass bed it builds has important ecological functions and economic value. As the most important primary producers on Earth, seagrass beds provide food and diverse habitats for numerous marine organisms. For coastal ecosystems, seagrass beds play a vital role in trapping sediment, stabilizing sediment, securing dikes, purifying water, cycling nutrients, and sequestering carbon (approximately 15% of the annual carbon sequestration of the entire marine ecosystem) It is often used as a biological indicator species for water quality and ecosystem health. [0003] Almost all seagrass beds worldwide are in decline due to changes in natural conditions and human activities. In order to restore seagrass r...

Problems solved by technology

[0005] The direct sowing method, the direct sowing method of seagrass seeds is the sowing method of directly sowing seaweed seeds on the water surface, which is the earliest sowing technology. This method has the advantages of simple operation and relatively low labor cost, but due to the large randomness of sowing seeds, Easy to lose, resulting in its seed germination rate is generally not higher than 10% burial method and seed protection sowing technology;

[0006] The artificial burial method is to manually bury seaweed seeds into the bottom mud of the seabed. This method can effectively reduce the loss of seeds, but unlike land operations, it is difficult to bury seaweed seeds into the bottom mud underwater, so there are labor-intensive, difficult operations and High labor costs and other issues

[0007] Seed protection sowing technology, such as the sack method is to manually put the seeds evenly into the sacks filled with soil, and then lay the sacks filled with seeds and soil and bury them on the seabed. This method better avoids the loss of seeds and is relatively Compared with artificial sowing and burial methods, seed protection and sowing technology can protect seagrass seeds more effectively, thereby increasing the average germination rate of seagrass seeds, but the process of protecting seaweed seeds requires a lot of manpower, material resources and time costs. Processes for efficient and cost-effective seagrass seed multiplication at scale;

[0008] In summary, among the currently known seagrass seed sowing methods, the direct sowing method is easy to lose seeds and has a low germination rate; The protection and treatment process of seaweed seeds requires a lot of manpower, material resources and time costs, with low efficiency and high cost
