Description

Technical Field

[0001] The utility model belongs to the technical field of seaweed sowing and seedling planting equipment, and specifically relates to a limiting mechanism, a planting shovel assembly and a seaweed planting machine. Background Art

[0002] Seaweed plays a very important role in the marine ecological environment. It is usually planted in shallow coastal areas. The planting methods include direct sowing and seedling transplanting. At present, seaweed planting, whether sowing or planting seedlings, usually relies on manual labor. Therefore, it can only be carried out when the shallow coastal planting area is exposed to the ground at low tide. The planting time is very limited. Therefore, the company is currently focusing on developing mechanical equipment that can perform efficient planting operations without being affected by shallow coastal waters.

[0003] At present, for mechanized seaweed planting operations, the problem of consistency of seaweed planting depth needs to be solved in view of the uneven underwater ground. At the same time, considering that the seedling planting depth should be greater than the sowing depth, if two sets of planting shovels are used for sowing and planting respectively, not only will the equipment cost increase, but the process of using planting shovels (each set of planting shovels includes dozens of shovel bodies arranged in rows) will be time-consuming and labor-intensive. Therefore, it is currently necessary to develop a planting shovel that can meet the needs of both sowing and planting operations. Utility Model Content

[0004] The embodiment of the utility model provides a limiting mechanism, which is intended to enable the planting shovel to have both sowing and seedling planting functions and to improve the consistency of seaweed planting depth.

[0005] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: in the first aspect, a limiting mechanism is provided to limit the depth of a planting shovel inserted into the underwater ground, the planting shovel includes a tube body for conveying seaweed seeds or seaweed seedlings downward, and a shovel body connected to the lower end of the tube body; the limiting mechanism includes a hoop seat, a limiting member connected to the hoop seat for sliding up and down, and a locking member provided on the limiting member; wherein the locking member is used to lock the upward and downward sliding freedom of the limiting member, the limiting member is located on the side of the shovel body, and is used to abut against the underwater ground to limit the depth of the shovel body inserted into the underwater ground.

[0006] In one possible implementation, the limiting member includes a plurality of sliding rods and limiting plates; wherein the sliding rods are spaced apart and are all connected to the hoop seat along the axial direction of the tube body for sliding connection, and at least one sliding rod is provided with a locking member; the limiting plate is fixedly connected to the lower end of each sliding rod, and the limiting plate is used to abut against the underwater ground.

[0007] In some embodiments, the hoop seat includes a hoop connected to the pipe body and a seat plate connected to the lower end of the hoop; wherein each sliding rod is slidably disposed up and down through the seat plate.

[0008] Exemplarily, the locking member includes two lock nuts spaced apart from each other in an upper and lower portion. The lock nut is sleeved on the slide bar and threadedly engaged with the slide bar. The two lock nuts are respectively in contact with upper and lower side surfaces of the seat plate.

[0009] For example, the hoop is an open ring, and both ends of the hoop are bent outward to form connecting ears, and the two connecting ears are connected by at least one fastener; the hoop seat includes two seat plates, which are respectively located on both sides of the two connecting ears and are respectively connected to the two connecting ears.

[0010] In a possible implementation, a plurality of gear ring platforms are spaced apart from each other on the lower end peripheral wall of the tube body, and the inner wall of the hoop is provided with at least one annular groove, each of which is respectively engaged with one of the gear ring platforms.

[0011] In some embodiments, a stop groove is provided on the gear ring platform, a stop rib is provided in the ring groove, and the stop rib is embedded in the stop groove.

[0012] Exemplarily, a plurality of water-permeable holes are spaced apart on the limiting plate.

[0013] The beneficial effect of the limiting mechanism provided by the utility model is that compared with the prior art, the limiting mechanism of the utility model is connected to the pipe body of the planting shovel through a hoop seat, and uses a locking piece to lock the distance between the limiting piece and the hoop seat. Since the limiting piece is located on the side of the shovel body, the insertion depth of the shovel body can be limited by the limiting piece abutting against the underwater ground during the insertion of the shovel body into the underwater ground, thereby ensuring the consistency of the seaweed planting depth. After loosening the locking piece, the height of the limiting piece can be adjusted by sliding the limiting piece up and down. After adjusting to the right position, the locking piece is re-locked to adjust the depth of the shovel body inserted into the underwater ground. Not only can the limit piece be raised to meet the needs of seaweed large-depth planting operations, but the limit piece can also be lowered to meet the needs of seaweed small-depth sowing operations, thereby enabling the seaweed planting machine to have two operation modes of sowing and seedling planting without replacing the sowing shovel.

[0014] In a second aspect, an embodiment of the utility model further provides a planting shovel assembly, including a planting shovel body and the above-mentioned limiting mechanism.

[0015] The beneficial effect of the planting shovel assembly provided by the utility model is that compared with the prior art, the planting shovel assembly of the utility model adopts the above-mentioned limiting mechanism. During the process of the shovel body being inserted into the underwater ground, the insertion depth of the shovel body can be limited by the limiting piece abutting against the underwater ground, thereby ensuring the consistency of the seaweed planting depth. After loosening the locking piece, the height of the limiting piece can be adjusted by sliding the limiting piece up and down. After adjusting to the right position, the locking piece is re-locked to adjust the depth of the shovel body inserted into the underwater ground. Not only can the limit piece be raised to meet the needs of seaweed planting operations at a large depth, but the limit piece can also be lowered to meet the needs of seaweed sowing operations at a small depth. Therefore, the seaweed planting machine can have two operation modes, namely sowing and seedling planting, without replacing the sowing shovel.

DETAILED DESCRIPTION

[0022] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0023] It should be noted that when an element is referred to as being "disposed on" or "connected to" another element, it may be directly on the other element or indirectly on the other element. It should be understood that the terms "length", "width", "upper", "lower", "front", "back", "top", "bottom", "inside", "outside", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application. In the description of the present application, "multiple" and "several" mean two or more, unless otherwise clearly and specifically defined.

[0024] Please also read Figures 1 to 3 The limiting mechanism provided by the utility model is now described. The limiting mechanism is used to limit the depth of the planting shovel 10 inserted into the underwater ground. The planting shovel 10 includes a tube body 11 for conveying seaweed seeds or seaweed seedlings downward, and a shovel body 12 connected to the lower end of the tube body 11; the limiting mechanism includes a hoop seat 20, a limiting member 30 connected to the hoop seat 20 for sliding up and down, and a locking member 40 provided on the limiting member 30; wherein the locking member 40 is used to lock the upward and downward sliding freedom of the limiting member 30, the limiting member 30 is located on the side of the shovel body 12, and is used to abut the underwater ground to limit the depth of the shovel body 12 inserted into the underwater ground.

[0025] It should be noted that the planting shovel 10 in this embodiment can be installed on a seaweed planting machine for mechanized seaweed planting operations, or can be manually held to carry out seaweed planting operations. It should be understood that, whether it is sowing or planting seedlings, in order to resist the scouring force of seawater, the roots of seaweed seeds and seaweed seedlings need to be tied with a gravity ball. On the one hand, the gravity of the gravity ball is used to prevent the seaweed seeds or seaweed seedlings from being separated from the underwater ground due to the buoyancy of seawater, and on the other hand, the falling force of the gravity ball can be used to make the seaweed seeds or seaweed seedlings sink into the water during sowing or planting. When sowing seaweed, first loosen the locking member 40 and adjust the limit member 30 to the target height (specifically, the distance between the tip of the shovel body 12 and the abutment surface of the limit member 30 is consistent with the sowing depth of the seaweed seeds). Then, re-lock the limit member 30 through the locking member 40 and insert the shovel body 12 of the planting shovel 10 downward into the underwater ground to the depth at which the limit member 30 abuts against the surface of the underwater ground. Then, the seaweed seeds tied with the gravity ball are placed into the tube body 11 from the top. Driven by the gravity ball, the seaweed seeds move down along the tube body 11. When planting seaweed seedlings, readjust the height of the limiter 30 so that the distance between the abutting surface of the limiter 30 and the tip of the shovel body 12 is consistent with the depth of the seaweed seedlings. Then, insert the shovel body 12 into the underwater ground until the limiter 30 abuts against the surface of the underwater ground. Then, put the seaweed seedlings tied with the gravity ball into the tube body 11 from the top, so that the seaweed seedlings fall into the planting pit dug by the shovel body 12 along the tube body 11 under the driving force of the falling gravity ball.

[0026] It should be noted that the above-mentioned shovel body 12 can be a flat shovel body 12. After being inserted into the underwater ground, the tube body 11 is swung to form a planting pit suitable for the roots of seaweed seeds or seaweed seedlings to enter the underwater ground, and the tube body 11 is swung back after the roots of the seaweed seeds or seaweed seedlings enter the pit to return the turned-up soil to its original position, thereby completing the planting process; the above-mentioned shovel body 12 can also be an openable and closable structure composed of a fixed shovel and a movable shovel. When the movable shovel is closed, it forms a pointed cone shape with the fixed shovel to facilitate insertion into the underwater ground. After the shovel body 12 is inserted into place, the starting shovel is turned on (the switch of the movable shovel can be controlled by a pull wire) to turn up the soil on the side of the insertion position to form a planting pit. After the roots of the seaweed seeds or seaweed seedlings enter the planting pit, the planting shovel 10 is lifted, and the movable shovel is turned off at the same time to return the turned-up soil to its original position, thereby completing the planting process.

[0027] Compared with the prior art, the limiting mechanism provided in the present embodiment is connected to the tube body 11 of the planting shovel 10 through the hoop seat 20, and the locking member 40 is used to lock the distance between the limiting member 30 and the hoop seat 20. Since the limiting member 30 is located on the side of the shovel body 12, the limiting member 30 can abut the underwater ground during the insertion of the shovel body 12 into the underwater ground to limit the insertion depth of the shovel body 12, thereby ensuring the consistency of the seaweed planting depth. After loosening the locking member 40, the height of the limiting member 30 can be adjusted by sliding the limiting member 30 up and down. After adjusting to the right position, the locking member 40 is re-locked to adjust the depth of the shovel body 12 inserted into the underwater ground. Not only can the limiting member 30 be raised to meet the needs of seaweed large-depth planting operations, but the limiting member 30 can also be lowered to meet the needs of seaweed small-depth sowing operations, thereby enabling the seaweed planting machine to have two operation modes of sowing and seedling planting without replacing the sowing shovel.

[0028] In some embodiments, see Figure 1 and Figure 2 The above-mentioned limiting member 30 includes a plurality of slide bars 31 and a limiting plate 32; wherein the slide bars 31 are distributed at intervals and are all connected to the hoop seat 20 along the axial direction of the pipe body 11 by sliding, and at least one slide bar 31 is provided with a locking member 40; the limiting plate 32 is fixedly connected to the lower end of each slide bar 31, and the limiting plate 32 is used to abut the underwater ground.

[0029] Since the underwater ground is usually soft, the use of a limit plate 32 that abuts against the underwater ground to limit the planting depth can improve the reliability of the limit; on this basis, the limit plate 32 is connected to the bottom of the hoop seat 20 through multiple sliding rods 31. The structure is simple and stable. At the same time, the height of the limit plate 32 can be easily adjusted by sliding the sliding rod 31 up and down on the hoop seat 20, thereby adjusting the planting depth. After adjustment, the corresponding sliding rod 31 is axially locked using the locking piece 40 to avoid the limit plate 32 moving up and down during the planting process and causing planting depth deviation.

[0030] As a specific embodiment of the hoop seat 20, please refer to Figure 2 The hoop seat 20 includes a hoop 21 connected to the tube body 11 and a seat plate 22 connected to the lower end of the hoop 21; wherein each slide bar 31 is slidably arranged on the seat plate 22. By connecting the seat plate 22 to the hoop 21, it is convenient to punch holes and arrange the slide bars 31, so that the slide bars 31 and the seat plate 22 can slide up and down together. The structure is simple and practical. At the same time, the hoop 21 and the tube body 11 are sleeved in a way that the connection position can be adjusted up and down after the hoop 21 is loosened, thereby driving the limit plate 32 to adjust the height, thereby increasing the height adjustment range of the limit plate 32, thereby meeting the operation requirements of different seaweed planting depths.

[0031] As a specific structural form of the locking member 40, please refer to Figure 2 The locking member 40 includes two lock nuts spaced apart from each other. The lock nuts are sleeved on the slide bar 31 and screwed together with the slide bar 31. The two lock nuts are respectively in contact with the upper and lower side plate surfaces of the seat plate 22. The two lock nuts are screwed on the slide bar 31 at the upper and lower sides of the seat plate 22, respectively, so as to form a structure in which the two lock nuts clamp the seat plate 22 and lock the sliding freedom of the slide bar 31 relative to the seat plate 22. When the limit plate 32 needs to be adjusted in height, it only needs to screw the two lock nuts. The operation is simple and the locking is stable and reliable.

[0032] Some possible implementations include Figure 2 As shown, the hoop 21 is an open ring, and the two ends of the hoop 21 are bent outward to form connecting ears 212, and the two connecting ears 212 are connected by at least one fastener 23; the hoop seat 20 includes two seat plates 22, and the two seat plates 22 are respectively located on both sides of the two connecting ears 212 and are respectively connected to the two connecting ears 212. The end of the hoop 21, the connecting ear 212 and the seat plate 22 connected to the two are connected to form a corner structure, thereby improving the overall structural rigidity and reliability, and avoiding the problem of connection failure between the seat plate 22 and the hoop 21 due to frequent impact force during planting operations; the relative position of the hoop 21 on the pipe body 11 can be adjusted up and down by loosening the fastener 23, and the fastener 23 can be re-fixed after adjustment. Specifically, in order to improve the clamping force and connection reliability of the hoop 21 on the pipe body 11, two fasteners 23 can be arranged at intervals up and down. The fastener 23 can be a bolt and a nut. The bolt passes through the two connecting ears 212 in turn and is connected to the nut. The two connecting ears 212 are brought close to each other by tightening the nut, thereby forming a clamping connection to the pipe body 11.

[0033] Please note that, see Figure 2 and Figure 3 In this embodiment, the lower end peripheral wall of the tube body 11 is provided with a plurality of gear ring platforms 111 at intervals, and the inner wall of the hoop 21 is provided with at least one annular groove 211, and each annular groove 211 is respectively engaged with one of the gear ring platforms 111. The engagement between the gear ring platform 111 and the annular groove 211 can prevent the hoop 21 from sliding and dislocating on the tube body 11 and affecting the height of the limit plate 32, thereby ensuring the consistency of the seaweed planting depth; when the height of the limit plate 32 needs to be adjusted, the fastener 23 is loosened to expand the hoop 21 so that the gear ring platform 111 is disengaged from the annular groove 211, and then the annular groove 211 is adjusted to the right position so that the gear ring platform 111 is aligned and engaged with the gear ring platform 111 at the corresponding position, and then the fastener 23 is tightened again.

[0034] Further, such as Figure 2 and Figure 3As shown, a stop groove 1111 is provided on the gear ring platform 111, a stop rib 2111 is provided in the ring groove 211, and the stop rib 2111 is embedded in the stop groove 1111. Since the tube body 11 is usually a cylindrical structure, in order to prevent the ring hoop 21 from rotating on the tube body 11 and affecting the stability of the limiting plate 32, the stop rib 2111 is provided to cooperate with the stop groove 1111 to limit the rotational freedom of the ring hoop 21.

[0035] It should be noted that if Figure 2 As shown, in order to reduce the downward resistance of the seawater to the limit plate 32 during the insertion of the planting shovel 10 into the underwater ground, a plurality of water-permeable holes 321 are spaced apart on the limit plate 32 in this embodiment. During the planting process, when the planting shovel 10 moves up and down in the seawater, especially when the shovel body 12 is inserted into the soil, the seawater can pass through the water-permeable holes 321 to reduce the resistance to the limit plate 32, thereby improving the labor-saving use of the planting shovel 10.

[0036] Based on the same inventive concept, Figures 1 to 3 It is understood that the embodiment of the present application also provides a planting shovel assembly, including a planting shovel 10 body and the above-mentioned limiting mechanism.

[0037] Compared with the prior art, the planting shovel assembly provided in the present embodiment adopts the above-mentioned limiting mechanism. During the process of the shovel body 12 being inserted into the underwater ground, the limiting member 30 can abut against the underwater ground to limit the insertion depth of the shovel body 12, thereby ensuring the consistency of the seaweed planting depth. After loosening the locking member 40, the height of the limiting member 30 can be adjusted by sliding the limiting member 30 up and down. After adjusting to the right position, the locking member 40 is re-locked to adjust the depth of the shovel body 12 inserted into the underwater ground. Not only can the limit member 30 be raised to meet the needs of seaweed planting operations at a large depth, but the limit member 30 can also be lowered to meet the needs of seaweed sowing operations at a small depth. This enables the seaweed planting machine to have two operation modes, namely sowing and seedling planting, without replacing the sowing shovel.

[0038] Based on the same inventive concept, an embodiment of the utility model also provides a seaweed planting machine, including the above-mentioned planting shovel assembly.

[0039] Compared with the prior art, the seaweed planting machine provided in this embodiment adopts the above-mentioned planting shovel assembly, which can not only ensure the consistency of seaweed planting depth on uneven underwater ground, but also has two operation modes of sowing and seedling planting without replacing the sowing shovel.

[0040] 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.
