Description

Technical Field

[0001] This invention relates to the field of marine ecological restoration technology, and in particular to the field of seagrass bed ecological restoration technology. Background Technology

[0002] Seagrass beds are among the most productive ecosystems in the Earth's biosphere, serving as vital ecological corridors and an important component of the "fishpond reef" community. They play a crucial role in improving and regulating the ecological environment. However, since 1990, global seagrass beds have been decreasing at a rate of 7% per year. Seagrass bed protection and restoration have attracted significant attention and become a hot topic in contemporary ecological restoration.

[0003] The main methods for seagrass bed restoration include seeding, transplantation, and habitat restoration, with seeding and transplantation being the primary methods currently. However, the seeding rate is relatively low, mainly because seeds are easily washed away by ocean currents or consumed by marine animals in the seabed environment. Therefore, seeds generally need to be pre-made into mud pellets before sowing. The demand for mud pellets is large, but the efficiency of artificially pre-making mud pellets is too low to meet the sowing needs. Summary of the Invention

[0008] The rounding and forming structure is located directly below the aforementioned sandwich discharge and shaping short tube (14), and from top to bottom includes a mud column shear (15), a rounding disc (16), and a mud ball funnel (17).

[0009] The mud column shear (15) is hydraulically driven, and the hydraulic system includes an axially horizontal hydraulic cylinder (21) and a piston (22). The outer shell of the hydraulic cylinder (21) is fixedly supported on the bracket (20). The bottom center of the piston (22) is simultaneously hinged to one end of the first connecting rod (23) and one end of the second connecting rod (24). The other end of the first connecting rod (23) is hinged to one end of the third connecting rod (26), and the other end of the second connecting rod (24) is hinged to one end of the fourth connecting rod (27). The third connecting rod (26) and the fourth connecting rod (27) are cross-hinged at the middle position. A first cutting edge (28) and a second cutting edge (29) are respectively provided on the inner side from the hinge point to the end. The first connecting rod (23), the second connecting rod (24), the third connecting rod (26), the fourth connecting rod (27), the first cutting edge (28), and the second cutting edge (29) are coplanar and horizontal. The first cutting edge (28) and the second cutting edge (29) are located directly below the sandwich discharge shaping short tube (14) and can perform shearing activities in the horizontal plane to shear the vertical mud column (30) coming down from the sandwich discharge shaping short tube (14). The hinge point of the first connecting rod (23) and the third connecting rod (26), the second connecting rod (27), and the second cutting edge (29) are respectively provided on the inner side from the hinge point to the end. 4) The hinge points of the first link (23) and the third link (26), and the hinge points of the second link (24) and the fourth link (27) all fall within the fixed guide groove (25). The fixed guide groove (25) is a horizontal cuboid structure with its length direction perpendicular to the axis of the hydraulic cylinder (21). The hinge points of the first link (23) and the third link (26), and the hinge points of the second link (24) and the fourth link (27) slide within the fixed guide groove (25) along the length direction of the fixed guide groove (25). The working process of the mud column shears (15) is as follows: When the piston (22) is located at the outermost axial end of the hydraulic cylinder (21), the hinge points of the first link (23) and the third link (26), and the hinge points of the second link (24) and the fourth link (27) slide within the fixed guide groove (25) along the length direction of the fixed guide groove (25). The hinge points of the second link (24) and the fourth link (27) slide to the two ends of the fixed guide groove (25), that is, one end of the third link (26) and one end of the fourth link (27) slide to the two ends of the fixed guide groove (25). Since the middle part of the third link (26) and the fourth link (27) are hinged together, under the action of the lever, the other end of the third link (26) and the other end of the fourth link (27) open to the maximum in opposite directions. The mud column (30) falls from the opening under the extrusion of the aforementioned bottom material feeding metering screw (6) and seed batching feeding metering screw (12).When the piston (22) moves into the hydraulic cylinder, it drives the hinge points of the first connecting rod (23) and the third connecting rod (26), and the hinge points of the second connecting rod (24) and the fourth connecting rod (27) to slide towards the middle along the fixed guide groove (25). That is, one end of the third connecting rod (26) and one end of the fourth connecting rod (27) slide towards the middle along the fixed guide groove (25). Since the middle part of the third connecting rod (26) and the fourth connecting rod (27) are hinged together, under the action of the lever, the other end of the third connecting rod (26) and the other end of the fourth connecting rod (27) also close towards the middle. When the piston (22) reaches the highest point, the other end of the third connecting rod (26) and the other end of the fourth connecting rod (27) merge. Under the action of the inner blades of the two connecting rods, the mud column (30) is cut off, becoming a short column mud blank before the mud ball is formed.

[0010] The rolling disc (16) is located below the mud column shears (15), and includes a drive motor (37), a drive shaft (38), a moving mold (31), a stationary mold (32), a mud blank inlet (33), and a mud ball outlet (34). The moving mold (31) has a semi-circular inwardly concave groove ring on the outer circumference of the cylinder. The stationary mold (32) has two coaxial and parallel circular plates with a gap between them. The outer circumferences of the two circular plates are connected and fixed by an arc-shaped concave panel. The inner surface of the arc-shaped concave panel is a semi-circular outwardly concave groove. The arc length corresponds to the circumferential length of the connection between the outer circumferences of the two circular plates by the arc-shaped concave panel. The arc length is greater than 1 / 12 and less than 1 / 2 of the circumference. The arc-shaped concave panel is located on the outer circumference of the groove ring of the moving mold (31) and forms a circular channel with a closed cross section. The two circular plates of the stationary mold (32) correspond to end flanges. The two end flanges are coaxially located at both ends of the cylinder of the moving mold (31) and are connected to the mating flanges. The mating flange is fixedly supported on the bracket (20); the housing of the drive motor (37) is fixedly supported on the bracket (20), the drive motor (37) is located outside one of the mating flanges of the stationary mold (32), the drive shaft (38) is driven by the drive motor (37), and passes through the center hole corresponding to the end face flange of the stationary mold (32) and the center hole corresponding to the cylinder of the moving mold (31). The drive shaft (38) is not fixedly connected to the stationary mold (32), and the drive shaft (38) is connected to the moving mold (31). The cylinder is rigidly connected, and the drive motor (37) drives the moving mold (31) cylinder to rotate in a circular motion through the drive shaft (38), while the stationary mold (32) is fixed on the support (20) and remains stationary, so that the moving mold (31) and the stationary mold (32) move relative to each other; one end of the arc-shaped concave plate of the stationary mold (32) is set as the mud inlet (33) corresponding to the falling position of the mud blank cut into the mud column (30), and one end of the arc-shaped concave plate is set as the mud ball outlet (34) at the bottom;

[0011] The mud ball funnel (17) is located below the rolling disc (16). The outer shell of the mud ball funnel (17) is fixedly supported on the bracket (20). The mud ball funnel (17) consists of an upper conical funnel and a lower vertical short tube. The inlet of the upper conical funnel is directly opposite the mud ball outlet (34) of the rolling disc (16).

[0012] The mud ball tray structure is located below the aforementioned mud ball funnel (17), specifically including a conveyor belt (18) and mud ball trays (19). The rollers of the front and rear rollers corresponding to the conveyor belt (18) are supported on the bracket (20). Multiple empty mud ball trays (19) are placed sequentially on the conveyor belt (18). The empty mud ball trays (19) move under the action of the conveyor belt (18) to the outlet of the vertical short pipe directly below the mud ball funnel (17) for receiving mud balls formed from the rounding mechanism.

[0013] The bottom material feeding slide (5) and the seed batching feeding slide (11) are both unloading slides, mainly used for unloading viscous sludge-like materials with poor flowability in the silo, and are mature devices.

[0014] A method for producing pre-made seaweed seed pellets using the aforementioned automated device includes the following steps:

[0015] Step 1: Substrate preparation: Using clay feeding and metering structure (1), fine sand feeding and metering structure (2), and substrate water supply and metering structure (3), appropriate amounts of clay, fine sand, and seawater are supplied to the substrate mixing tank (35), wherein the mass ratio of clay to fine sand is 3:1. The substrate is stirred evenly by the substrate mixing mixer (4) to prepare a substrate with a water content of 60-70%, which is then buffered in the substrate mixing tank (35).

[0016] Step 2: Preparation of seed ingredients: Using the seed ingredient clay feeding and metering structure (7), seed feeding and metering structure (8), and seed ingredient water feeding and metering structure (9), appropriate amounts of clay, seaweed seeds, and seawater are supplied to the seed ingredient mixing box (36). The mass ratio of clay to seeds is determined by the sowing density of seaweed seeds. The seeds are mixed evenly by the seed ingredient mixing mixer (10) to prepare seaweed seed ingredients with a moisture content of 80-90%, and then buffered in the seed ingredient mixing box (36).

[0017] Step 3: Preparation of mud pellets: The prepared substrate in the substrate mixing box (35) is fed into the inlet of the substrate feeding metering screw (6) via the substrate feeding slide (5), and then squeezed into the tail outlet via the substrate feeding metering screw (6) to form a substrate mud column; at the same time, the prepared seed ingredients in the seed mixing box (36) are fed into the inlet of the seed ingredients feeding metering screw (12) via the seed ingredients feeding slide (11), and then squeezed into the tail outlet via the seed ingredients feeding metering screw (12), and squeezed into the outlet of the substrate feeding metering screw (6) via the seed ingredients discharge shaping long pipe (13), located in the center of the substrate mud discharge, wrapped by the substrate mud column, forming a seed-filled mud column, and the mud column is discharged through the core discharge shaping short pipe (14); the above-mentioned core mud column discharge is cut by mud column shears ( 15) Cut into short column shape. During the cutting process, the mud column shears (15) squeeze the bottom material around the mud column to the center, wrapping the seaweed seeds inside the short column mud from top to bottom, thus forming a mud embryo. Then the mud embryo falls into the mud embryo inlet of the lower rolling disc (16) and enters the channel with a closed circular cross-section composed of the moving mold (31) and the stationary mold (32). In the relative rotational motion of the moving mold and the stationary mold, the short column mud embryo is ground into a circle and comes to the mud ball outlet of the rolling disc (16) along the channel, and then falls into the mud ball funnel (17), and then into the mud ball plate (19) through the mud ball funnel (17). As the mud balls are prepared, empty mud ball plates (19) are continuously sent to the bottom of the mud ball funnel (17) by the action of the conveyor belt (18). After the mud ball plate (19) is full, it is manually removed and dried for later use.

[0018] This invention has the following advantages:

[0019] 1. This automated device pre-makes seaweed seed pellets, replacing the manual preparation of seaweed seed pellets. It has high operating efficiency and low cost, and can meet the needs of large-scale seaweed seed sowing.

[0020] 2. The seaweed seeds in the device are carried into the core of the mud ball by the clay. The seaweed seeds are fed evenly, which will not cause the mud ball to be hollow or waste due to too many seaweed seeds.

[0021] 3. In this device, the size of the mud balls can be adjusted according to the diameter of the discharge short pipe of the sandwich mud column, and the encapsulation density of the seaweed seeds can also be adjusted by the ratio of clay and seed feed in the seed mix, making it easy to operate.
