[0026] Please also read Figures 1 to 6The dual-purpose shovel for seaweed sowing and seedling planting provided by the utility model is now described. The dual-purpose shovel for seaweed sowing and seedling planting includes a feeding pipe 10, a planting shovel 20, an opening and closing driving member 30, and a limit assembly 40; the feeding pipe 10 is used to convey the seaweed seeds or seaweed seedlings put in from its top downward; the planting shovel 20 is connected to the lower end of the feeding pipe 10, and includes a fixed shovel 21 and a moving shovel 22, and the moving shovel 22 can swing relative to the fixed shovel 21 to open or close; when the moving shovel 22 is closed, it is inserted into the underwater ground together with the fixed shovel 21, and when the moving shovel 22 is opened, it turns up the soil A planting pit is formed for seaweed seeds or seaweed seedlings to fall into; an opening and closing drive member 30 is provided on the drop tube 10 and connected to the movable shovel 22, for driving the movable shovel 22 to open or close; a limit assembly 40 is connected to the lower end of the drop tube 10, and has an adjustable limit plate 41 located on the side of the fixed shovel 21, and the distance between the adjustable limit plate 41 and the lower end of the planting shovel 20 is adjustable; wherein, when the planting shovel 20 is inserted into the underwater ground, the adjustable limit plate 41 is used to abut the underwater ground to control the depth of the planting pit.

[0027] It should be understood that the adjustable limit plate 41 in this embodiment can be adjusted by sliding up and down along the axial direction of the drop tube 10 relative to the movable shovel 22 and cooperating with the locking member to lock the position after sliding into place, so that the adjustable limit plate 41 can be raised to allow the planting shovel 20 to be inserted deeper into the underwater ground to form a planting pit suitable for planting seedlings, and the adjustable limit plate 41 can be lowered to allow the planting shovel 20 to be inserted shallower into the underwater ground to form a planting pit suitable for sowing. Considering that the formation of the planting pit requires squeezing and turning up the soil on the side of the movable shovel 22 during the opening process, the adjustable limit plate 41 is set on the side of the movable shovel 22 in this embodiment, thereby preventing the adjustable limit plate 41 from pressing against the underwater ground and affecting the formation of the planting pit.

[0028] Compared with the prior art, the dual-purpose shovel for seaweed sowing and seedling planting provided in this embodiment is smaller in distance between the adjustable limit plate 41 and the lower end of the planting shovel 20 according to the sowing depth requirement during seaweed sowing operation. After being adjusted to the right position, the movable shovel 22 is kept in a closed state and inserted into the underwater ground together with the fixed shovel 21 until the adjustable limiter abuts against the underwater ground. Then, the movable shovel 22 is driven to open by the opening and closing driving member 30. During the opening process of the movable shovel 22, the soil on the side thereof is squeezed and turned up to form a planting pit. Then, the seaweed seeds are put in from the top of the drop tube 10 so that the seaweed seeds fall into the planting pit through the drop tube 10. Then, the planting shovel 20 is lifted upward, and the opening and closing driving member 30 is opened at the same time. The movable member 30 drives the movable shovel 22 to close, thereby completing a sowing process; when planting seaweed seedlings, the distance between the adjustable limit plate 41 and the lower end of the planting shovel 20 is increased according to the planting depth requirements, thereby increasing the depth of the planting pit relative to the sowing operation. After the adjustment is completed, the seedling planting operation can be carried out in the same operating method as the sowing operation. The operation is simple and universal. Only the limit component 40 needs to be adjusted to meet the sowing operation and seedling planting operation requirements without replacing the planting shovel 20. Not only can it greatly save equipment costs, but it can also save the time for disassembling and replacing the planting shovel 20, thereby improving the efficiency of seaweed planting operations.

[0029] In some embodiments, see Figure 1 and Figure 3 The limit assembly 40 includes a mounting seat 42 and an adjustable limit plate 41; wherein the mounting seat 42 is fixedly mounted on the lower end of the blanking tube 10; a plurality of connecting rods 411 extending vertically upward are arranged at intervals on the adjustable limit plate 41, and each connecting rod 411 slides through the mounting seat 42 and is screwed to the first fastener 412 on both sides of the mounting seat 42. Here, the connecting rod 411 can be a screw, and the first fastener 412 can be a nut. Loosening the first fastener 412 can release the upward and downward sliding freedom of each connecting rod 411, thereby adjusting the height of the adjustable limit plate 41. After adjusting to the right position, tighten the first fastener 412 again, so that the first fasteners 412 on both sides of the mounting seat 42 cooperate to constrain the axial movement of the connecting rod 411 to ensure the stability of the adjustable limit plate 41. The adjustment process is simple and convenient, which can reduce equipment downtime and help promote work efficiency.

[0030] For details, please refer to Figure 3 and Figure 5The mounting seat 42 includes an open sleeve 421 and a connecting plate 422; wherein the open sleeve 421 is sleeved around the blanking tube 10 and the two ends are bent to form connecting ears 4211, and the two connecting ears 4211 are connected by a second fastener 4212 so that the open sleeve 421 clamps the blanking tube 10; the connecting plate 422 is provided with a through hole 4221 that is slidably matched with each connecting rod 411. The open sleeve 421 clamps the blanking tube 10 based on the connecting ears 4211 that are fastened and connected by the second fastener 4212 (specifically, it can be a bolt and a nut) at both ends. When the second fastener 4212 is loosened, the height of the open sleeve 421 can be adjusted up and down, thereby driving the height of the adjustable limit plate 41 connected to the connecting plate 422 to change accordingly. After adjusting to the right position, the second fastener 4212 is re-tightened, thereby cooperating with the adjustable limit plate 41's own adjustment ability to further increase its up and down adjustment range, thereby meeting the diversified operation requirements of the seaweed planting depth.

[0031] For some possible implementations, see Figure 2 and Figure 5 The side wall of the open sleeve 421 is provided with a stop groove 4213 at a position opposite to the connecting ear 4211, and the lower end side wall of the blanking tube 10 is provided with a convex seat 11, which is slidably engaged in the stop groove 4213. The position opposite to the connecting ear 4211 is the midpoint of the open sleeve 421 in the unfolded state. The stop groove 4213 is provided to cooperate with the convex seat 11 on the blanking tube 10 to ensure that the positions of the open sleeve 421 on both sides of the stop groove 4213 shrink in the same amount during the process of tightening the blanking tube 10, thereby improving the fixing stability of the open sleeve 421 on the blanking tube 10. At the same time, the engagement of the stop groove 4213 and the convex seat 11 can avoid the problem of loose connection caused by the open sleeve 421 being rotated by force, further improving the connection stability of the open sleeve 421 and the blanking tube 10, and thus ensuring the stability of the adjustable limit plate 41 against the underwater ground.

[0032] Optionally, the optional structure of the opening and closing driving member 30 in this embodiment is as follows: Figures 1 to 3 As shown, it includes an operating handle 31, a pull wire 32, and an elastic pushing member 33; wherein the operating handle 31 is arranged at the top end of the drop tube 10; one end of the pull wire 32 is connected to the operating handle 31, and the other end passes through the convex seat 11 and is connected to the movable shovel 22, and is used to pull the movable shovel 22 to open under the drive of the operating handle 31; the elastic pushing member 33 is sleeved on the pull wire 32, and is used to push the shovel 22 to make the movable shovel 22 swing to a closed state.

[0033] Here, the operating handle 31 can be rotated to wind up the pull wire 32 so that the pull wire 32 pulls the movable shovel 22, thereby overcoming the elastic force to open the movable shovel 22, or it can swing up and down to drive the pull wire 32 to pull the movable shovel 22 to open. When the operating handle 31 is released, the movable shovel 22 swings back and closes under the elastic force of the elastic pushing member 33, and the operation is convenient and labor-saving.

[0034] For example, see Figures 2 to 4 A stop plate 111 is provided on the boss 11, which extends in a direction away from the blanking tube 10 and extends out of the anti-rotation groove 4213, and a traction plate 221 is provided on the movable shovel 22, which extends in a direction away from the fixed shovel 21; wherein, the pull wire 32 passes through the stop plate 111 and is connected to the traction plate 221, and the two ends of the elastic pushing member 33 are respectively abutted against the stop plate 111 and the traction plate 221.

[0035] The traction plate 221 is used to form a force point on the movable shovel 22 to connect with the pull wire 32. The elastic pushing member 33 can be a spring. Since the elastic pushing member 33 is sleeved on the pull wire 32, and the pull wire 32 passes through the stop plate 111 and is connected to the traction plate 221, the stability of the elastic pushing member 33 between the traction plate 221 and the stop plate 111 can be ensured, and the elastic pushing member 33 is used to push the traction plate 221 elastically to drive the movable shovel 22 to close. The elastic force on the traction plate 221 is more direct and sufficient, thereby ensuring the closing tightness of the movable shovel 22.

[0036] It should be noted that, in this embodiment, Figure 2 and Figure 4 As shown, the traction plate 221 is located at the upper edge of the moving shovel 22, and a hinge seat 2211 extending upward is provided at a position of the traction plate 221 close to the moving shovel 22, and the moving shovel 22 is hinged to the convex seat 11 through the hinge seat 2211. The hinge seat 2211 is integrated on the traction plate 221, and the hinge seat 2211 is hingedly matched with the convex seat 11, thereby improving the compactness of the connection structure of the moving shovel 22, thereby ensuring the smoothness of the surface of the moving shovel 22, and avoiding too many structural parts on the surface of the moving shovel 22 affecting the smoothness of its insertion or extraction from the underwater ground.

[0037] For example, Figure 1 and Figure 6 As shown, the drop tube 10 is provided with a handle 12 near its top, and the operating handle 31 is hinged below the handle 12. The operator holds the handle 12 to exert an upward and downward force on the drop tube 10 to insert or pull out the planting shovel 20 from the underwater ground. At the same time, the operating handle 31 is hinged below the handle 12, so that the operator can hold the handle 12 and exert force on the operating handle 31 with his fingers, thereby generating traction on the pull line 32 by swinging the operating handle 31, and the operation is simple and convenient.

[0038] In order to satisfy the adjustability of the opening degree of the moving shovel 22, as Figure 6As shown, the operating handle 31 has a plurality of connection holes 311 spaced apart along its length direction, and one end of the pull wire 32 is provided with a connector 321, which is screwed to one of the connection holes 311. By changing the connection position of the connector 321, the distance between the connector 321 and the hinge axis of the operating handle 31 can be adjusted, thereby adjusting the stroke of the operating handle 31 pulling the pull wire 32 at the same swing angle, thereby adjusting the opening degree of the movable shovel 22.

[0039] Based on the same inventive concept, Figures 1 to 6 It is understood that the embodiment of the present application also provides a seaweed planting machine, including a machine body, and a plurality of the above-mentioned dual-purpose shovels for seaweed sowing and seedling planting, wherein the drop pipe 10 is slidably connected to the machine body up and down.

[0040] It should be noted that the function of the machine body in this embodiment is to provide an operating platform for the operator. At the same time, the machine body can be moved in the planting area to adjust the planting position. At the same time, the drop pipe 10 of the above-mentioned seaweed sowing and seedling dual-purpose shovel is connected to the machine body by sliding up and down. Therefore, the operator only needs to lift or press down the drop pipe 10 to insert or pull out the sowing shovel from the underwater ground, thereby reducing the labor intensity of the operator and avoiding the problem of planting position deviation caused by manually holding the drop pipe 10 for operation, which is beneficial to improving the uniformity of seaweed planting spacing.

[0041] Compared with the prior art, the seaweed planting machinery provided in this embodiment adopts the above-mentioned dual-purpose shovel for seaweed sowing and seedling planting. It only needs to adjust the limit component 40 to meet the needs of sowing operations and seedling planting operations without replacing the planting shovel 20. It can not only greatly save equipment costs, but also save the time for disassembly and replacement of the planting shovel 20, thereby improving the efficiency of seaweed planting operations.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
