[0033] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0034] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0035] See attached Figure 1 -Attached Fig.13, an automated device for seagrass bed ecological restoration, comprising a first discharging hopper 12, and also comprising a first feeding mechanism and a second feeding mechanism. The first feeding mechanism and the second feeding mechanism have the same structure, and the first feeding mechanism and the second feeding mechanism are both installed with the first discharging hopper 12, and the first feeding mechanism is arranged above the second feeding mechanism. The first feeding mechanism comprises two fixed plates 1, and two rotating plates 2 are symmetrically and rotatably installed at one end of the two fixed plates 1, and a conveying roller 3 is rotatably installed between the outer surfaces of the two fixed plates 1 and the two rotating plates 2 at both ends away from each other, and the outer surfaces of the two conveying rollers 3 are sleeved with a conveyor belt 4, and the outer surface of the conveyor belt 4 is evenly and fixedly installed with multiple receiving plates 7, and a shovel plate 10 is fixedly installed between the outer surfaces of the two rotating plates 2 away from the fixed plate 1, and the first feeding mechanism and the second feeding mechanism are both installed with a soil turning mechanism at one end close to the shovel plate 10, and the second feeding mechanism is away from One end of the soil turning mechanism passes through the outer surface of the first discharge hopper 12 and is fixedly installed with the second discharge hopper 13, the outer surface of the rotating plate 2 is fixedly installed with a driving motor 21, the output end of the driving motor 21 passes through the outer surface of the rotating plate 2 and is fixedly installed with the rotation center of the corresponding conveying roller 3, the outer surfaces of the two fixed plates 1 of the first feeding mechanism are fixedly installed with brackets 18, and the outer surface of the bottom end of the bracket 18 is rotatably installed with walking wheels 19, and the outer surfaces of the two fixed plates 1 of the first feeding mechanism close to the first discharge hopper 12 are also fixedly installed with traction frames 20, and the tops of the two fixed plates 1 of the first feeding mechanism are fixedly installed with a mixing hopper 34, and the mixing hopper 34 is filled with seaweed seeds and soil remediation agents, and a discharging port is opened at the bottom of the mixing hopper 34, so that the seaweed seeds and soil remediation agents can be sprinkled into the surface soil through the discharging port to sow and repair the surface soil.

[0036] In this embodiment, guide grooves 6 are provided on the outer surfaces of the fixed plate 1 and the rotating plate 2 on the side close to the conveyor belt 4, and multiple guide pillars 5 are fixedly installed at equal intervals on the side of the conveyor belt 4. The guide pillars 5 are slidably installed on the inner walls of the guide grooves 6, and a tensioning assembly is installed between the corresponding two rotating plates 2.

[0037] When in use, the conveyor belt 4 drives the guide pillars 5 on its sides to slide in the guide grooves 6 , so that the guide pillars 5 and the guide grooves 6 can limit the position of the conveyor belt 4 .

[0038] In this embodiment, the tensioning assembly includes a spring rod 8 fixedly installed between the corresponding two rotating plates 2. The telescopic end of the spring rod 8 is rotatably installed with a tensioning roller 9. The tensioning roller 9 abuts against the inner side of the conveyor belt 4. The outer surface of the rotating plate 2 near the tensioning roller 9 is provided with a clearance groove. The clearance groove can allow the guide column 5 installed on the side of the conveyor belt 4 to have a certain amount of movement space when the position of the tensioning roller 9 abutting against the conveyor belt 4 changes, thereby preventing the conveyor belt 4 from getting stuck.

[0039] When the height of the soil-turning mechanism installed on the turntable 2 is adjusted, the conveyor belt 4 installed on the turntable 2 will bend at different angles accordingly. The tensioning roller 9 is pushed by the spring rod 8 to always press against the inner side of the conveyor belt 4, which can ensure that the conveyor belt 4 always maintains a certain tension and prevents the conveyor belt 4 from slipping.

[0040] In this embodiment, a lifting mechanism is installed on the outer side of the first feeding mechanism and the second feeding mechanism. The lifting mechanism includes a hydraulic telescopic rod 11 rotatably installed between the fixed plate 1 and the outer surface of the rotating plate 2 away from the conveyor belt 4.

[0041] When in use, the hydraulic telescopic rod 11 drives the rotating plate 2 to rotate, and the height of the soil turning mechanism installed on the rotating plate 2 can be adjusted so that the soil turning mechanism can perform soil turning operations on soil layers of different depths.

[0042] In this embodiment, an arc-shaped material baffle plate 14 is fixedly installed on the inner wall of the first discharging hopper 12, and the arc-shaped material baffle plate 14 is arranged above the second feeding mechanism, and two downward discharge channels are formed between the two ends of the arc-shaped material baffle plate 14 and the inner walls on the opposite sides of the first discharging hopper 12. Two auger shafts 15 with spiral blades rotating in opposite directions are rotatably installed between the inner walls on the opposite sides of the first discharging hopper 12, and the two auger shafts 15 are fixedly installed between their axis centers. Pulleys 16 are fixedly installed at the rotation center of the auger shaft 15 and a conveying roller 3 close to the first discharging hopper 12, and belts 17 are sleeved on the outer surfaces of the two pulleys 16.

[0043] When in use, after the conveyor belt 4 of the first feeding mechanism conveys the surface soil to the arc-shaped baffle plate 14 in the first discharging hopper 12, the two auger shafts 15 installed in the first discharging hopper 12 will rotate under the transmission action of the pulley 16 and the belt 17, so that the auger shafts 15 with two spiral blades rotating in opposite directions can discharge the surface soil from the discharge channels on both sides of the first discharging hopper 12, so as to spread the surface soil in the ditch shoveled out by the soil-turning mechanism installed on the second feeding mechanism. At the same time, the two auger shafts 15 can drive the surface soil to mix with the seaweed seeds and the soil remediation agent when rotating, so that the seaweed seeds and the soil remediation agent can be more evenly mixed into the surface soil and improve and repair the surface soil.

[0044] In this embodiment, the soil turning mechanism includes a rotating drum 22 rotatably installed between two rotating plates 2, and support tubes 24 are fixedly installed at both end portions of the rotating drum 22. The support tubes 24 penetrate the outer surface of the rotating plate 2 and are rotatably installed therewith. A plurality of groups of blades 23 are inserted through the outer circumference of the rotating drum 22 in groups of two at equal intervals and staggered. A thrust spring 25 is fixedly installed between one end of the blade 23 inserted into the rotating drum 22 and the inner wall of the rotating drum 22. A transmission assembly is installed between the support tube 24 and a conveying roller 3 away from the first discharging hopper 12. The transmission assembly includes a sprocket 26 fixedly installed at the support tube 24 and the rotation center of the conveying roller 3. Chains 27 are sleeved on the outer surfaces of the two sprockets 26. A protective cover 32 is fixedly installed on the outer surface of the rotating plate 2 close to the chain 27. An ejection mechanism for intermittently ejecting the plurality of groups of blades 23 is installed inside the rotating drum 22.

[0045] When the conveying roller 3 rotates, the sprocket 26 and the chain 27 drive the support pipe 24 to rotate, so that the support pipe 24 drives the rotating drum 22 to rotate, so that the multiple sets of blades 23 installed on the rotating drum 22 can perform deep plowing operations on the soil.

[0046] In this embodiment, the ejection mechanism includes a moving rod 28 inserted through the inside of the rotating drum 22, and a square rod 29 is fixedly installed on one end of the moving rod 28 near the protective cover 32. The square rod 29 penetrates the outer surface of the protective cover 32 and is slidably installed therewith. A plurality of groups of conical disks 31 are symmetrically fixedly installed in groups of two on the outer surface of the moving rod 28, and the conical surfaces of the conical disks 31 are abutted against the outer surfaces of the corresponding blades 23. A reciprocating assembly is installed between the square rod 29 and the support tube 24, and the reciprocating assembly includes a fixed column 30 fixedly installed on the outer surface of the square rod 29, and a closed-loop guide groove 33 is opened on the inner wall of a support tube 24 near the square rod 29, and the fixed column 30 is slidably installed on the inner wall of the closed-loop guide groove 33.

[0047] When the support tube 24 drives the rotating drum 22 to rotate, the closed-loop guide groove 33 opened on the inner wall of the support tube 24 at one end will drive the square rod 29 to move back and forth along the axial direction of the moving rod 28 through the fixed column 30, so that the multiple conical disks 31 installed on the moving rod 28 can move back and forth accordingly. When the conical disk 31 moves, the corresponding blade 23 can be pushed outward through the conical surface, so that the pushed out blade 23 turns the soil, and the blade 23 that is separated from the conical surface of the conical disk 31 will be retracted into the rotating drum 22 under the elastic force of the thrust spring 25, and the soil will no longer be turned over. The soil is turned over by switching different blades 23 back and forth.

[0048] From the above description, it can be seen that the above-mentioned embodiment of the present invention achieves the following technical effects: when in use, the traction frame 20 is fixedly installed with the traction vehicle, so that the traction vehicle pushes the device to move in the seaweed bed through the traction frame 20; the conveying roller 3 is driven to rotate by the driving motor 21, so that the conveyor belt 4 sleeved on the outer surface of the conveying roller 3 can drive the receiving plate 7 to move toward the top of the device, so that the soil shoveled out by the soil turning mechanism and the shovel plate 10 is respectively conveyed to the first discharge hopper 12 and the second discharge hopper 13, and the soil turning mechanism installed on the first feeding mechanism and the soil turning mechanism installed on the second feeding mechanism are respectively conveyed to the first discharge hopper 12 and the second discharge hopper 13. The mechanism respectively spreads the soil on the surface of the seaweed bed and the deeper soil back to the surface through the first discharge hopper 12 and the second discharge hopper 13, so that the deeper soil covers the surface soil. By deep plowing the surface soil and the deeper soil in sequence, the soil of the seaweed bed can be deeply processed, the soil structure and quality can be further improved, the soil depth can be increased, and more root growth space can be provided, which is conducive to the growth of seaweed and the root taking root; and the two sets of soil turning mechanisms are used successively to deep plow the seaweed bed, which can avoid the disadvantage of using the rotary tiller to turn the soil too deep at a time, resulting in excessive power consumption;

[0049] While the first feeding mechanism is conveying the surface soil, the seaweed seeds and soil remediation agent in the mixing hopper 34 can be spread and mixed in the surface soil to facilitate the subsequent growth of the seaweed seed root system;

[0050] After the conveyor belt 4 of the first feeding mechanism conveys the surface soil to the arc-shaped baffle plate 14 in the first discharging hopper 12, the two auger shafts 15 installed in the first discharging hopper 12 will rotate under the transmission action of the pulley 16 and the belt 17, so that the auger shafts 15 with two spiral blades rotating in opposite directions can discharge the surface soil from the discharge channels on both sides of the first discharging hopper 12, so as to spread the surface soil in the trench shoveled by the soil turning mechanism installed on the second feeding mechanism. At the same time, the two auger shafts 15 can drive the surface soil to mix with the seaweed seeds and the soil remediation agent when rotating, so that the seaweed seeds and the soil remediation agent can be more evenly mixed into the surface soil and improve and repair the surface soil;

[0051] When the conveying roller 3 rotates, the sprocket 26 and the chain 27 drive the support tube 24 to rotate, so that the support tube 24 drives the rotating drum 22 to rotate, so that the multiple sets of blades 23 installed on the rotating drum 22 can perform deep plowing operations on the soil;

[0052] When the support tube 24 drives the rotating drum 22 to rotate, the closed-loop guide groove 33 opened on the inner wall of the support tube 24 at one end will drive the square rod 29 to move back and forth along the axial direction of the moving rod 28 through the fixed column 30, so that the multiple conical disks 31 installed on the moving rod 28 can move back and forth accordingly. When the conical disk 31 moves, the corresponding blade 23 can be pushed outward through the conical surface, so that the pushed out blade 23 turns the soil, and the blade 23 separated from the conical surface of the conical disk 31 will be retracted into the rotating drum 22 under the elastic force of the thrust spring 25, and no longer turns the soil. By switching different blades 23 back and forth to turn the soil, each blade 23 has time to get a full rest and cool down, and the blade 23 will not be blunted due to continuous work, avoiding the situation of being worn by the soil for a long time, thereby extending the service life of the blade 23, and using the blade 23 in turn can maintain the sharpness of the blade 23, maintaining the stability and efficiency of the turning effect.

[0053] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
