Description

Multi-shovel type seaweed sampler

Technical Field

The utility model belongs to the technical field of the plant is transplanted, especially, relate to many shovel formula seaweed samplers.

Background

Sea grass is one of the most important primary producers in the world and is also an important part of the food chain of the marine ecosystem, and a sea grass bed has a very complex community structure, provides an important habitat and a concealed protection place for some juvenile fishes and shellfishes, and does not provide a foraging place for some phytophagous fishes, some water birds, some large animals and the like.

With the gradual understanding of the ecological function of the seaweed bed, the protection of the seaweed bed and the restoration of the damaged biological community are more and more paid attention. The sea grass transplanting method is a method of collecting sea grass plants with good growth vigor from a sea grass bed with vigorous natural growth and transplanting the sea grass plants to a sea area to be restored by using a certain method or device. The seaweed plant transplantation is to carry out different collection and planting on the transplantation unit. At present, the collection of the seaweed mainly adopts a grass block method and a rhizome method, wherein the grass block method is to collect cylindrical, cuboid or other irregular grass blocks with certain unit volume as a transplanting unit through a sampler, the grass blocks comprise complete substrate and rhizome, and the substrate is a foundation for fixing the root system of the seaweed and a carrier for absorbing nutrient substances by the seaweed; the rootstock method is to collect the rootstock directly, excluding the substrate.

Conventional samplers use a shovel or hoe to dig out the specimen. When the rhizome method is adopted, the seaweed is directly dug by using an iron shovel, the convenience is realized, the collection of the grass block method cannot be met, the size of the directly dug grass block is different, the grass block cannot be completely attached to the planting hole, the problem that the grass block is larger than or smaller than the planting hole can be solved, the planting hole needs to be repainted according to the shape of the grass block, and a large amount of time is wasted.

SUMMERY OF THE UTILITY MODEL

The utility model discloses a basic scheme: the multi-shovel type seaweed sampler comprises a square collecting frame formed by enclosing four plates, wherein a through groove is formed in the lower portion of one plate of the collecting frame along the length direction of the collecting frame, a vertical plate is fixed on the plate provided with the through groove, the vertical plate is provided with an opening communicated with the through groove, a cavity communicated with the opening is formed in the vertical plate along the height direction of the vertical plate, a vertically arranged chain plate and a horizontally arranged expansion plate are arranged in the cavity, the lower end of the chain plate is located at the opening of the vertical plate, the lower end of the chain plate is connected with one end of the expansion plate, and the other end of the expansion plate is connected to the inner wall of the; the lower end of the chain plate is connected with a first blade, and the upper end of the chain plate is connected with a push rod extending out of the top of the vertical plate; the lower edges of the four plates of the collecting frame are provided with rotatable rotating shafts along the length direction, two ends of each rotating shaft are provided with driven bevel gears, the driven bevel gears at the end parts of the adjacent rotating shafts are meshed with each other, and one side of each rotating shaft, which is far away from the plates, is provided with a second blade; the plate with the through grooves penetrates through a supporting rod in the height direction, the supporting rod is located right above the driven bevel gears on the same side, the upper ends of the supporting rods are connected to the tops of the vertical plates in a clamped mode, and driving bevel gears meshed with the driven bevel gears located right below the supporting rods are arranged at the lower ends of the supporting rods.

The working principle and the beneficial effects of the basic scheme are as follows: the collection frame extends into the substrate of the seaweed, and the second blade cuts the substrate, so that the collection frame can move downwards until the collection frame extends into the substrate of the seaweed. Then push out the link joint through the logical groove on following the board of gathering the frame through the push rod, the first blade on the link joint is with the sea grass cutting on the bottom and the bottom on the link joint, and the expansion plate plays the effect of support to the link joint to the collection of grass piece has been realized to the sea grass in gathering the frame region. Because the square area of the collecting frame is fixed, the sizes of the grass blocks collected each time are consistent, and the planting holes for the subsequent planting of the grass blocks are uniform.

When gathering the rhizome of sea grass, the bracing piece rotates, under drive bevel gear and driven bevel gear's combined action, makes the pivot rotate to adjust the gradient of connecting the second blade in the pivot, then gather the frame through reciprocating, the second blade is in order to realize the excavation to the substrate, perhaps positive and negative rotation bracing piece constantly adjusts the gradient of second blade, in order to realize the loose of substrate, alright pull out sea grass at last.

This scheme can be applicable to the seaweed collection of grass piece method and rhizome method, not only can dig the grass piece of getting the size unanimity, can also easily dig the pine substrate, realizes the collection of rhizome, convenient operation, and the practicality is strong.

Further, the push rod is equipped with a plurality of through-holes along its length direction, the top of riser is equipped with the fixing base, fixing base threaded connection has the bolt that is used for running through the through-hole.

The push rod is fixed through a bolt and is used for controlling the extending condition of the chain plate.

Further, a roller in contact with the chain plate is rotatably connected to the communication position of the cavity and the opening.

The convenient chain plate is easier to extend out of the opening.

Further, the top of the push rod is provided with a holding part.

The seaweed sampler is convenient to take and place.

Furthermore, a groove capable of accommodating the first blade is formed in the plate, opposite to the through groove, of the collecting frame, and a rubber layer is arranged in the groove.

When the seaweed sampler is used, the first blade is positioned in the groove, so that the first blade is prevented from cutting the board and damaging the board.

Furthermore, the number of the supporting rods is two, and the two supporting rods are respectively positioned right above the two driven bevel gears on the same side.

By rotating the two support rods, the driving bevel gears of the two support rods respectively drive the two driven bevel gears at the same side so as to provide larger transmission force.
