Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present application, the meanings of "multiple" and "several" are two or more, unless otherwise clearly and specifically defined.

[0024] Please also read Figures 1 to 5 The crab-walking seaweed planting machine provided by the utility model is now described. The crab-walking seaweed planting machine includes a crab-walking body 10, a planting slide 20, and a hydraulic pump station 40; the crab-walking body 10 has a plurality of transverse legs 11 and a plurality of longitudinal legs 12, and both the transverse legs 11 and the longitudinal legs 12 have a supporting state of abutting the underwater ground, and a suspended state separated from the underwater ground; the planting slide 20 is connected to the front side of the body along the longitudinal sliding, and a plurality of planting guns 30 are arranged at intervals along the transverse direction on the planting slide 20, and the planting guns 30 are used to be inserted downward into the underwater ground to form a planting pit, and are used to guide seaweed seeds / seedlings to fall into the planting pit; the hydraulic pump station 40 is arranged on the crab-walking body 10, and is connected to each transverse leg 11 and each longitudinal leg 12, and is used to drive each transverse leg 11 to extend and retract vertically and horizontally, and is used to drive each longitudinal leg 12 to extend and retract vertically and longitudinally.

[0025] It should be noted that, in the present embodiment, the crab-walking body 10 realizes a crab-like walking based on the mutual cooperation of the transverse legs 11 and the longitudinal legs 12. Specifically, when lateral movement is required, the longitudinal legs 12 are suspended in the air, and then the hydraulic pump station 40 drives the transverse legs 11 on one side of the crab-walking body 10 to extend laterally, and the transverse legs on the other side to contract laterally, so that the crab-walking body 10 moves laterally one step, and then the longitudinal legs 12 support the underwater ground, the transverse legs 11 are suspended in the air and move in the opposite direction in the lateral direction, and then the transverse legs 11 support the underwater ground again while the longitudinal legs 12 are suspended in the air again, so that the transverse legs 11 on both sides of the crab-walking body 10 are retracted and extended again to walk one step, and this is repeated until the specified position is reached; the longitudinal movement process is the same as the lateral movement method, and will not be described in detail again.

[0026] In this embodiment, the telescopic movements of each transverse support leg 11 and each longitudinal support leg 12 are driven by a hydraulic cylinder. Each hydraulic cylinder is connected to a hydraulic pump station 40, and the hydraulic pump station 40 provides hydraulic power to each transverse support leg 11 and each longitudinal support leg 12 to realize their respective independent telescopic movements.

[0027] In this embodiment, the lateral spacing of the planting gun 30 matches the lateral spacing of seaweed plants. The longitudinal sliding of the planting slide 20 can be continuous or step-by-step, and the distance of each sliding step is equal to the longitudinal spacing of seaweed plants. The gun head of the planting gun 30 can be a duckbill type or a pointed cone type that can be opened and closed. It can be inserted downward into the underwater ground and then opened to squeeze the soil on the side to form a planting pit. Then the operator puts seaweed seeds or seaweed seedlings into the planting gun 30 from the planting slide 20. The seaweed seeds or seaweed seedlings fall freely (the roots of the seaweed seeds or seaweed seedlings are tied with gravity balls) and enter the planting pit, and then the planting gun 30 can be pulled out upward.

[0028] Compared with the prior art, the crab-climbing seaweed planting machine provided in the present embodiment uses each lateral support leg 11 and each longitudinal support leg 12 to support the underwater ground and maintain the stable support state of the crab-climbing body 10 during seaweed planting operations, so as to facilitate the operator to operate each planting gun 30 on the planting slide 20 to perform seaweed planting operations. Each operator can operate multiple planting guns 30, thereby reducing the demand for operators and reducing labor costs. After planting a horizontal row of seaweed, the planting slide 20 can slide longitudinally once to plant the next row of seaweed, which can not only ensure the uniformity of the seaweed planting spacing, but also improve the seaweed planting efficiency. When all the planting is completed within the longitudinal movement range of the planting slide 20, the crab-climbing body 10 can be driven to move horizontally and vertically in the water by alternately supporting the underwater ground with the lateral support legs 11 and the longitudinal support legs 12, so as to enter the next planting area for operation, thereby realizing underwater planting operations, avoiding the limiting influence of tides on the seaweed planting time, and improving the time flexibility of seaweed planting operations.

[0029] In some embodiments, see Figure 1 The transverse moving leg 11 includes a transverse moving telescopic cylinder 111 and a transverse moving support cylinder 112. The transverse moving telescopic cylinder 111 is laterally connected to the crab-walking body 10, and the transverse moving support cylinder 112 is connected to the telescopic end of the transverse moving telescopic cylinder 111; the longitudinal moving leg 12 includes a longitudinal moving telescopic cylinder 121 and a longitudinal moving support cylinder 122. The longitudinal moving telescopic cylinder 121 is longitudinally connected to the crab-walking body 10, and the longitudinal moving support cylinder 122 is connected to the telescopic end of the longitudinal moving telescopic cylinder 121.

[0030] Here, the longitudinal movement of the crab-walking body 10 is used for explanation. During normal planting operations, each lateral support leg 11 and each longitudinal support leg 12 are supported on the underwater ground, thereby ensuring the stable posture of the crab-walking body 10. When longitudinal movement is performed (seaweed planting has been completed on the front side, usually moving backward), each lateral support cylinder 112 is contracted and lifted to form a suspended state, and then the longitudinal telescopic cylinder 121 on the front side of the crab-walking body 10 is extended, and the longitudinal telescopic cylinder 121 on the rear side is shortened synchronously, thereby causing the crab-walking body 10 to move backward as a whole. The moving distance is the telescopic stroke of the longitudinal telescopic cylinder 121, which can be regarded as one longitudinal step, and then the lateral support cylinder 112 is retracted and lifted. The support cylinders 112 are extended to support the underwater ground until each longitudinal support cylinder 122 is separated from the underwater ground to form a suspended state, and then each longitudinal telescopic cylinder 121 moves in the opposite direction (i.e., the front longitudinal telescopic cylinder 121 retracts and the rear longitudinal telescopic cylinder 121 extends), and then each transverse support cylinder 112 contracts and becomes suspended again, and the crab-walking body 10 moves backward one longitudinal step driven by each transverse telescopic cylinder 111, and this is repeated until it reaches the specified position; the crab-walking body 10 performs transverse movement in a similar manner to the longitudinal movement process, using the longitudinal support cylinder 122 to alternately switch between the support state and the suspended state, and the transverse telescopic cylinder 111 to alternately extend and retract to complete the transverse step movement.

[0031] For some possible implementations, see Figure 1 The crab-walking body 10 has a plurality of track beams 13 spaced apart in the transverse direction, each track beam 13 extends longitudinally to the front of the crab-walking body 10, and the planting slide 20 is slidably connected to each track beam 13. The use of a plurality of track beams 13 to carry the planting slide 20 can improve the stability of the planting slide 20, and make the planting slide 20 suspended on the side of the crab-walking body 10, thereby preventing the crab-walking body 10 from interfering with the movement of the planting gun 30, and at the same time, it can also provide a larger longitudinal moving space for the planting slide 20, thereby increasing the operating area of ​​the planting slide 20, thereby increasing the area where seaweed can be planted after the crab-walking body 10 moves into position each time, and improving the seaweed planting efficiency.

[0032] In some embodiments, see Figure 1The crab-traveling machine body 10 is provided with a fixed seat 14, and the planting slide 20 is provided with an axle seat 21. The axle seat 21 is provided with a lead screw 211 that is rotatably matched with the lead screw 211. One end of the lead screw 211 passes through the fixed seat 14 and is threadedly matched with the fixed seat 14. The other end of the lead screw 211 is provided with an operating hand wheel 212. Before the planting process of a horizontal row of seaweed is completed, the operator can rotate the lead screw 211 by rotating the operating hand wheel 212, thereby using the threaded match between the lead screw 211 and the fixed seat 14 to drive the planting slide 20 to move longitudinally. Since the thread pitch of the lead screw 211 is fixed, the longitudinal moving distance of the planting slide 20 can be accurately controlled by the number of turns of the rotating operating hand wheel 212, thereby ensuring that the longitudinal spacing of the seaweed planting is accurate and consistent.

[0033] For some possible implementations, see Figure 1 and Figure 2 A plurality of sliding holes are arranged at intervals along the horizontal direction on the planting slide 20, and a support rod 22 is arranged on the side of each sliding hole; wherein, each planting gun 30 is respectively slidably passed through each sliding hole and rotatably cooperated with the sliding hole, and a handle 300 is arranged at the top end of each planting gun 30 along its radial direction, and the handle 300 is used to overlap the top end of the support rod 22 to keep the planting gun 30 in a suspended standby state.

[0034] The sliding hole is used to form a radial constraint on the planting gun 30, so that the planting gun 30 can form a straight up and down movement to ensure the accuracy of the seaweed planting position. The operator holds the handle 300 for easy operation, which is beneficial to improving the seaweed planting efficiency. At the same time, after completing the planting of a seaweed, the planting gun 30 can be rotated so that its handle 300 overlaps the support rod 22 to form a standby state, and then the next planting gun 30 can be operated, thereby realizing the operation mode of a single person operating multiple planting guns 30, thereby reducing labor, not only ensuring the spaciousness of the operating space, but also saving labor costs.

[0035] It should be noted that if Figure 2 and Figure 3 As shown, the top of the support rod 22 is provided with an arc-shaped support plate 221 for supporting the handle 300, and the bottom end of the support rod 22 passes through the planting slide 20 and is provided with a sleeve 222, which is slidably sleeved on the planting gun 30 and rotates with the planting gun 30. The arc-shaped support plate 221 can improve the support stability of the handle 300, and the sleeve 222 at the bottom end of the support rod 22 can increase the constraint point of the planting gun 30, thereby improving the stability of the planting gun 30 sliding up and down, and preventing the planting gun 30 from shaking and increasing the difficulty of seaweed planting operation.

[0036] As a specific embodiment of the above-mentioned planting gun 30, please refer to Figures 2 to 5The planting gun 30 includes a gun barrel 31, a fixed shovel 32 and a movable shovel 33, an opening and closing handle 34, and an elastic reset member 36; the gun barrel 31 is vertically slidably penetrated in the sliding hole and rotatably cooperates with the sliding hole, and the gun barrel 31 is used to downwardly transport seaweed seeds / seedlings inserted from its top; the fixed shovel 32 is fixedly connected to the lower end of the gun barrel 31; the movable shovel 33 is hinged to the lower end of the gun barrel 31 and is arranged opposite to the fixed shovel 32, and the movable shovel 33 has a closed state in which it swings to connect with the fixed shovel 32 to form a pointed cone, and an open state in which it swings to separate from the fixed shovel 32; the opening and closing handle 34 is hinged to the lower side of the grip 300 and is connected with a pull wire 35, which passes through the support rod 22 and is connected to the movable shovel 33; the elastic reset member 36 is sleeved on the pull wire 35, one end of which is connected to the lower end of the gun barrel 31, and the other end is connected to the movable shovel 33, and the elastic reset member 36 is used to elastically push the shovel 33 to close the movable shovel 33.

[0037] When planting seaweed, the operator first rotates the gun barrel 31 to disengage the handle 300 from the support rod 22, then slides the gun barrel 31 downward to insert the fixed shovel 32 and the movable shovel 33 into the underwater ground in a closed state, and then the operator pulls the opening and closing handle 34 upward with four fingers to swing the opening and closing handle 34 upward and form a traction force on the pull line 35, so that the movable shovel 33 is opened under the traction of the pull line 35, and the movable shovel 33 is squeezed during the opening process to form a planting pit, and then the operator operates A person flips the seaweed seeds or seaweed seedlings into the planting pit from the top of the gun barrel 31, so that the seaweed seeds or seaweed seedlings fall into the planting pit along the gun barrel 31, and then lifts the gun barrel 31 upward to drive the opened fixed shovel 32 and the movable shovel 33 to pull out the seaweed seeds or seaweed seedlings from the planting pit. During the pulling out process, the seaweed seeds or seaweed seedlings fall from the gap opened by the fixed shovel 32 and the movable shovel 33, and at the same time, the soil squeezed by the fixed shovel 32 falls into the planting pit to cover the roots of the seaweed seeds or seaweed seedlings, thereby completing the planting process of one seaweed. The operation is simple and convenient.

[0038] like Figure 4 and Figure 5 As shown, in order to ensure the consistency of the seaweed planting depth, the lower end of the barrel 31 is sleeved with a hoop 311, and a connecting plate 312 is provided on the hoop 311. A limit plate 313 is connected below the connecting plate 312. The limit plate 313 is located on the side of the fixed shovel 32, and the limit plate 313 is used to abut the underwater ground to limit the depth of the fixed shovel 32 inserted into the underwater ground. When the movable shovel 33 and the fixed shovel 32 are inserted into the underwater ground together in a closed state, the limit plate 313 abuts against the underwater ground when inserted to the target depth, thereby limiting the fixed shovel 32 and the movable shovel 33 from continuing to be inserted, thereby ensuring that the depth of the planting pit is controllable, thereby improving the consistency of the seaweed planting depth; on this basis, since the planting depth requirements of seaweed seeds and seaweed seedlings are different, the height of the limit plate 313 can be adjusted by adjusting the position of the hoop 311 up and down, thereby adjusting the depth of the planting pit, thereby realizing the dual use of seaweed sowing and seaweed seedlings.

[0039] Specifically, see Figure 5 In this embodiment, a plurality of slide bars 314 are arranged at intervals on the above-mentioned limit plate 313, and each slide bar 314 slides upward and passes through the connecting plate 312. Two lock nuts 315 are screwed on at least one slide bar 314, and the two lock nuts 315 are respectively in contact with the upper and lower surfaces of the connecting plate 312. The slide bar 314 can be slid up and down by loosening the lock nut 315, so as to adjust the distance between the connecting plate 312 and the limit plate 313, thereby realizing the adjustment of the planting depth, and can cooperate with the up and down adjustment of the hoop 311 to increase the up and down adjustment range of the limit plate 313, thereby improving the applicable range of the planting gun 30 for different planting depths.

[0040] It should be understood that in this embodiment, see Figure 1 At least two transverse legs 11 are arranged at intervals along the longitudinal direction on both sides of the crab-walking body 10, and at least two longitudinal legs 12 are arranged at intervals along the transverse direction on both sides of the crab-walking body 10; a buoy 15 and a propeller 16 are arranged at the bottom of the crab-walking body 10, the buoy 15 is used to provide buoyancy to the crab-walking body 10 when the transverse legs 11 and the longitudinal legs 12 are both in a suspended state, and the propeller 16 is used to drive the floating crab-walking body 10 to move on the water surface.

[0041] During lateral or longitudinal movement, at least four lateral legs 11 or longitudinal legs 12 are always kept supporting the underwater ground, thereby ensuring the stability of the crab-walking movement of the crab-walking body 10. At the same time, for long-distance movement, each lateral leg 11 and each longitudinal leg 12 can be switched to a suspended state, and the float 15 is used to provide buoyancy to the crab-walking body 10 and the propeller 16 is used to drive the crab-walking body 10 to move to the target position, thereby improving the switching efficiency of the seaweed planting area.

[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.
