Description

Technical Field

[0001] The present invention relates to the field of marine aquaculture, and particularly to an efficient placing device and method for shell attachment bases of Porphyra haitanensis Background Art

[0002] During the filamentous seedling stage of Porphyra haitanensis, shells are used as attachment bases for cultivation. The shells need to be pre-cleaned and then neatly arranged in the seedling pond to provide a good attachment base and overall cultivation environment for the filamentous seedling cultivation of Porphyra haitanensis. However, currently, the inner shells are still placed one by one manually. On the one hand, the neatness is affected by human factors, and on the other hand, manual operation is time-consuming and laborious, with low efficiency. Summary of the Invention

[0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide an efficient placing device and method for shell attachment bases of Porphyra haitanensis. The mechanized structure and operation are used to replace manual labor to complete the placement of shell attachment bases, which is more time-saving and labor-saving, and can ensure the placement efficiency and neatness.

[0004] The present invention adopts the following technical solutions: An efficient placing device for shell attachment bases of Porphyra haitanensis includes a longitudinal conveying mechanism, a transverse conveying mechanism, a longitudinal conveyor belt, and a feeding mechanism. The longitudinal conveying mechanisms are symmetrically arranged on both sides of the seedling pond. The two ends of the transverse conveying mechanism are mounted on the longitudinal conveying mechanisms and span the seedling pond. The feeding mechanism is arranged at any one end (upper or lower) of the seedling pond. One end of the longitudinal conveyor belt is arranged at the transverse conveying mechanism, and the other end is connected to the output end of the feeding mechanism. The shells are conveyed to the seedling pond through the feeding mechanism and the longitudinal conveyor belt. The transverse conveying mechanism periodically drives the output end of the longitudinal conveyor belt to translate, so that when the shells fall into the seedling pond, they are arranged horizontally in a neat manner. The longitudinal conveying mechanism periodically drives the transverse conveying mechanism to move longitudinally, so that when the shells fall into the seedling pond, they are arranged longitudinally in several rows.

[0005] As an improvement, the longitudinal conveyor belt is made of an elastic material, is integrally formed, and is in a strip shape as a whole. The cross-section of the strip is V-shaped or U-shaped, so that the shells are accommodated at the lower position in the middle of the longitudinal conveyor belt. The output end of the feeding mechanism is the highest point, and the longitudinal conveyor belt is inclined for the shells to slide and be conveyed. The input end of the longitudinal conveyor belt is wound around a storage roller. When the position of the output end of the longitudinal conveyor belt changes, the storage roller correspondingly winds or releases the longitudinal conveyor belt.

[0006] As an improvement, a winding roller is further arranged before the storage roller. The winding roller and the storage roller are arranged in a top-down manner. The longitudinal conveyor belt passes around the winding roller from the highest point and is wound on the lower storage roller.

[0007] As an improvement, the output end of the longitudinal conveyor belt has an upwardly extending lifting section, which allows the conveyed shells to stay at the lowest point of the lifting section. A rotating plate is provided on the transverse conveying mechanism, and the rotating plate is located below the lifting section. When the rotating plate is driven to rotate, the rotating plate is made to resist the lifting section upward, so that the lowest point of the lifting section is lifted to the highest point, thereby allowing the shells to fall from the output end to the seedling pond.

[0008] As an improvement, the transverse conveying mechanism includes a arranging frame, a screw rod, a sliding rod and a mounting frame. The screw rod and the sliding rod are arranged in parallel and both ends are arranged on the mounting frame. The mounting frame is used to be detachably arranged on the longitudinal conveying mechanism; the arranging frame is passed through the screw rod and the sliding rod, and a slider is arranged on the arranging frame to cooperate with the screw rod for transmission. The mounting frame is provided with a motor for driving the screw rod to rotate periodically, thereby driving the arranging frame to perform translational adjustment; the output end of the longitudinal conveying belt is arranged at the arranging frame, a rotating plate is arranged on the arranging frame, and a cylinder is arranged to drive the rotating plate to swing up and down.

[0009] As an improvement, the longitudinal conveying mechanism includes a transmission wheel and a conveyor belt. The conveyor belt is wound in a ring shape on the transmission wheel. A plug hole is provided on the conveyor belt for detachable installation of the mounting frame. The transmission wheel is connected to a motor to drive the transmission wheel to rotate periodically.

[0010] As an improvement, the loading mechanism includes a loading conveyor wheel and a loading conveyor belt. The loading conveyor belt is wound in a ring shape on the loading conveyor wheel and is inclined so that the output end is located at the highest point and corresponds to the input end of the longitudinal conveyor belt. Soft partition plates are evenly arranged on the loading conveyor belt, and space for accommodating shells is formed between adjacent partition plates. When the partition plate runs to the highest point and flips downward, the upper end of the partition plate overlaps the input end of the longitudinal conveyor belt to form a connecting surface for shell transfer.

[0011] A method for placing an efficient Porphyra haitanensis shell attachment base, comprising:

[0012] Step 1: Arrange longitudinal conveying mechanisms on both sides of the nursery pool, arrange transverse conveying mechanisms on the longitudinal conveying mechanisms, arrange a loading mechanism at one end of the nursery pool, and arrange both ends of the longitudinal conveyor belt at the output ends of the transverse conveying mechanism and the loading mechanism;

[0013] Step 2: The shells are transported to the feeding mechanism by manpower or conveyor belts, and the feeding mechanism delivers the shells to the longitudinal conveyor belt, and the shells fall from the output end of the longitudinal conveyor belt to the nursery pond;

[0014] Step 3: The transverse conveying mechanism periodically moves left or right by a rated distance until the shells falling into the nursery pond through the longitudinal conveyor belt are neatly arranged in a row in the transverse direction;

[0015] Step 4: The longitudinal conveying mechanism makes a periodic longitudinal movement of a rated distance, and then repeats the step to arrange the shells in several rows longitudinally.

[0016] The beneficial effects of the present invention: By using a mechanized and automated structure and method to replace manual labor for arranging the shells, the shell arranging efficiency can be greatly improved, the neatness of shell arrangement can be ensured, and the liberated labor force only needs to carry out the equipment layout and maintenance, as well as the easier feeding and discharging processes, optimizing the labor force allocation, enabling a small amount of labor force to manage more nursery ponds simultaneously, and improving the cultivation efficiency of Porphyra haitanensis.

[0022] The following will describe the specific embodiments of the present invention in detail with reference to the accompanying drawings.

[0023] As Figures 1-5 shown, it is a specific embodiment of the high-efficiency Porphyra haitanensis shell attachment base placing device and method of the present invention.

[0024] An embodiment of a high-efficiency Porphyra haitanensis shell attachment base placing device includes a longitudinal conveying mechanism 1, a transverse conveying mechanism 2, a longitudinal conveyor belt 3, and a feeding mechanism 4. The longitudinal conveying mechanism 1 is symmetrically arranged on both sides of the nursery pond. The two ends of the transverse conveying mechanism 2 are mounted on the longitudinal conveying mechanism 1 and span across the nursery pond. The feeding mechanism 4 is arranged at any upper or lower end of the nursery pond. One end of the longitudinal conveyor belt 3 is arranged at the transverse conveying mechanism 2, and the other end is connected to the output end of the feeding mechanism 4. The shells are conveyed to the nursery pond through the feeding mechanism 4 and the longitudinal conveyor belt 3. The transverse conveying mechanism 2 periodically drives the output end of the longitudinal conveyor belt 3 to translate so that the shells are neatly arranged horizontally when falling into the nursery pond. The longitudinal conveying mechanism 1 periodically drives the transverse conveying mechanism 2 to move longitudinally so that the shells are arranged in several rows longitudinally when falling into the nursery pond.

[0025] A high-efficiency Porphyra haitanensis shell attachment base placing method includes

[0026] Step 1: Arrange the longitudinal conveying mechanism 1 on both sides of the seedling-raising pond, arrange the transverse conveying mechanism 2 on the longitudinal conveying mechanism 1, arrange the feeding mechanism 4 at one end of the seedling-raising pond, and arrange both ends of the longitudinal conveyor belt 3 at the output ends of the transverse conveying mechanism 2 and the feeding mechanism 4;

[0027] Step 2: Convey the shells to the feeding mechanism 4 manually or by the conveyor belt. The feeding mechanism 4 sends the shells to the longitudinal conveyor belt 3, and the shells fall from the output end of the longitudinal conveyor belt 3 into the seedling-raising pond;

[0028] Step 3: The transverse conveying mechanism 2 moves left or right periodically by a rated distance until the shells falling into the seedling-raising pond through the longitudinal conveyor belt 3 are neatly arranged in a row horizontally;

[0029] Step 4: The longitudinal conveying mechanism 1 moves longitudinally periodically by a rated distance, and then repeats Step 3 to arrange the shells in several rows longitudinally.

[0030] When the present invention is in use, the staff customize the longitudinally corresponding longitudinal conveying mechanism 1 and transverse conveying mechanism 2 according to the specifications of their own seedling-raising pond A, or set the corresponding specifications of the seedling-raising pond A according to the models of the most conventional standard longitudinal conveying mechanism 1 and transverse conveying mechanism 2; adopt two groups of longitudinal conveying mechanisms 1 on the left and right, symmetrically erected on both sides of the seedling-raising pond A, and then erect the upper transverse conveying mechanism 2 on the longitudinal conveying mechanism 1; then correspondingly arrange the feeding mechanism 4 at the middle of one end of the seedling-raising pond A for the input of the shells B, and arrange both ends of the longitudinal conveyor belt 3 at the transverse conveying mechanism 2 and the output end of the feeding mechanism 4. In the initial state, taking Figure 1 as an example, the initial position of the output end of the longitudinal conveyor belt 3 can be set at the far corner of the seedling-raising pond A, referring to Figure 1The longitudinal conveyor belt 3 with a dotted line in the middle conveys the shell B from the feeding mechanism 4 to the longitudinal conveyor belt 3, and then the shell B slides down from the longitudinal conveyor belt 3 and falls into the seedling rearing pond A. After the feeding of one shell B is completed, the transverse conveying mechanism 2 is started to move right by a rated distance and then stop, and then the next shell B is placed until a whole row of equidistant shells B is arranged; then the longitudinal conveying mechanism 1 is started to move towards one end of the feeding mechanism 4 by a rated distance and then stop, and then with the leftward movement of the transverse conveying mechanism 2 and the coordinated feeding at the feeding mechanism 4 and the longitudinal conveyor belt 3, the placement of the next row of shells B can be completed; repeating the above process, finally, multiple rows of equidistant and neatly arranged shells B are completed in the seedling rearing pond A. The staff can set the driving mechanism in the device of the present invention through the control module, so as to adjust the rated distance, and then match the sorting of shells B of different sizes; arranging the shells in a mechanized and automated manner instead of manually can greatly improve the efficiency of shell arrangement, ensure the neatness of shell arrangement, and the staff only needs to carry out the layout and maintenance of the equipment, as well as the easier feeding and receiving processes, optimize the allocation of labor, so that a small amount of labor can manage more seedling rearing ponds at the same time, and improve the cultivation efficiency of Porphyra haitanensis.

[0031] As an improved specific implementation manner, the longitudinal conveyor belt 3 is made of an elastic material, which is integrally formed and is in a strip shape as a whole. The cross-section of the strip is V-shaped or U-shaped, so that the shell is accommodated in the lower middle position of the longitudinal conveyor belt 3. The output end of the feeding mechanism 4 is the highest point. The longitudinal conveyor belt 3 is inclined for the downward sliding and conveying of the shell. The input end of the longitudinal conveyor belt 3 is wound around a storage roller 31, so that when the position of the output end of the longitudinal conveyor belt 3 changes, the storage roller 31 correspondingly winds or releases the longitudinal conveyor belt 3.

[0032] As Figure 1 、 2 、4, 5 show, the transverse conveying mechanism 2 drives the output end of the longitudinal conveyor belt 3 to move horizontally. The longitudinal conveyor belt 3 made of an elastic material can be stretched and reset to a certain extent, so as to match the adjustment after displacement and the need for the conveying of the shell B. As Figure 5The cross-section of the longitudinal conveyor belt 3 is set to be V-shaped or U-shaped, with the middle part being lower, which can limit the shell B well. The inclined longitudinal conveyor belt 3 enables the shell B not to shift from both sides or even fall out during the sliding transportation process, ensuring the stability of transportation. The longitudinal distance of the seedling cultivation pool A is relatively large. By means of the longitudinal conveyor belt 3 made of elastic material and being wound around the storage roller 31, when the transverse conveying mechanism 2 and the output end of the longitudinal conveyor belt 3 move towards the end where the feeding mechanism 4 is located, the longitudinal conveyor belt 3 can be wound around the storage roller 31, thereby shortening the length of the longitudinal conveyor belt 3, and further maintaining the appropriate length of the longitudinal conveyor belt 3, making the longitudinal conveyor belt 3 flat, and enabling the shell B to slide smoothly on it. The storage roller 31 is externally connected to a motor, and this motor can be periodically started and stopped through a control module, and cooperate with the position of the output end of the longitudinal conveyor belt 3 to wind or release the longitudinal conveyor belt 3 at the storage roller 31.

[0033] As a specific improved embodiment, a winding roller 32 is further provided in front of the storage roller 31. The winding roller 32 and the storage roller 31 are arranged vertically from top to bottom. The winding roller 32 allows the longitudinal conveyor belt 3 to bypass from the highest point and be wound around the lower storage roller 31.

[0034] As Figure 2 , 4 As shown, the upper winding roller 32 is used to keep the longitudinal conveyor belt 3 flat at the highest point, which can well dock with the input end of the feeding mechanism 4 to receive the shell B, and the excess longitudinal conveyor belt 3 is wound around the lower storage roller 31, which does not affect the normal transportation of the shell B, and is convenient for the storage of the excess longitudinal conveyor belt 3 and the connection with the external driving mechanism.

[0035] As a specific improved embodiment, the output end of the longitudinal conveyor belt 3 has a lifting section 30 extending upward. The lifting section 30 makes the conveyed shell stay at the lowest point of the lifting section 30. A rotating plate 20 is provided on the transverse conveying mechanism 2. The rotating plate 20 is located below the lifting section 30. When the rotating plate 20 is driven to rotate, the rotating plate 20 abuts upward against the lifting section 30, so that the lowest point of the lifting section 30 is lifted to the highest point, thereby making the shell fall from the output end into the seedling cultivation pool.

[0036] As Figure 2 As shown, the shell B slides from the high point of the longitudinal conveyor belt 3 to the low point until it falls into the seedling cultivation pool A, with a certain height. When the speed is too fast, there may be knocking and hitting on the shell B, resulting in damage to the shell B. Therefore, the lifting section 30 is provided. After the shell B slides and falls, it will reach the lowest point of the lifting section 30, and then the driving mechanism starts the rotating plate 20 to rotate and lift the lifting section 30, so that the lowest point is lifted to the highest point, and further the shell B continues to fall out into the seedling cultivation pool A, thus avoiding the knocking and hitting damage caused by the too fast falling speed of the shell B and the displacement that may be caused by inertia, and being able to better ensure that the shell B is arranged neatly and orderly and the whole is intact.

[0037] As an improved specific implementation method, the transverse conveying mechanism 2 includes an arrangement frame 21, a screw rod 22, a slide rod 23 and a mounting frame 24. The screw rod 22 and the slide rod 23 are arranged in parallel and both ends are arranged on the mounting frame 24. The mounting frame 24 is used to be detachably arranged on the longitudinal conveying mechanism 1; the arrangement frame 21 is passed through the screw rod 22 and the slide rod 23, and a slider is arranged on the arrangement frame 21 to cooperate with the screw rod 22 for transmission. The mounting frame 24 is provided with a motor for driving the screw rod 22 to rotate periodically, thereby driving the arrangement frame 21 to perform translational adjustment; the output end of the longitudinal conveying belt 3 is arranged at the arrangement frame 21, a rotating plate 20 is arranged on the arrangement frame 21, and a cylinder is arranged to drive the rotating plate 20 to swing up and down.

[0038] like Figure 1 , 2 As shown in Figure 3, the arrangement of the two rods of the screw rod 22 and the slide bar 23 ensures the stability of the displacement structure of the arrangement frame 21. The screw rod 22 and the slide bar 23 are arranged on the mounting frame 24 to stabilize the overall structure. The mounting frame 24 is specifically provided with a motor, and the start and stop of the motor is controlled by the control module. The rotation of the screw rod 22 can drive the arrangement frame 21 to move periodically, and the arrangement frame 21 can slide stably on the slide bar 23. The cylinder specifically arranged on the arrangement frame 21 can provide two stations of extension and retraction, thereby driving the rotating plate 20 to swing up and down. When swinging up, the lifting section 30 is lifted to make the shell B fall, and when swinging down, the lifting section 30 is avoided to reset it to receive the shell B. Overall, the simple structure effectively controls the cost and realizes the function well.

[0039] As an improved specific implementation method, the longitudinal conveying mechanism 1 includes a transmission wheel 11 and a conveyor belt 12. The conveyor belt 12 is wound around the transmission wheel 11 in a ring shape. A plug hole 13 is provided on the conveyor belt 12 for detachable installation of the mounting frame 24. The transmission wheel 11 is connected to a motor for driving the transmission wheel 11 to rotate periodically.

[0040] like Figure 1 , 3 As shown, the conveyor belt 12 is preferably wound into a ring shape through the structure of the front and rear two driving wheels 11, and a plurality of equidistant plug holes 13 are set on the surface of the conveyor belt 12, which can be disassembled and assembled accordingly in conjunction with the plug posts on the mounting frame 24, and the overall structure does not bear additional external forces. The above structure can ensure quick and convenient disassembly and assembly while controlling costs, and is convenient for staff to assemble and adjust, or select the plug holes 13 at appropriate positions according to the different longitudinal lengths of the seedling pool A to adjust the displacement range.

[0041] As a specific implementation of the improvement, the feeding mechanism 4 includes a feeding conveyor wheel 41 and a feeding conveyor belt 42. The feeding conveyor belt 42 is wound into a loop around the feeding conveyor wheel 41 and is inclined so that the output end is at the highest point and corresponds to the input end of the longitudinal conveyor belt 3. Soft partition plates 43 are evenly arranged on the feeding conveyor belt 42, and a space for accommodating the shells is formed between adjacent partition plates 43. When the partition plate 43 runs to the highest point and turns downward, the upper end of the partition plate 43 is placed on the input end of the longitudinal conveyor belt 3 to form a connecting surface for shell transfer.

[0042] As Figure 4 shown, preferably, the feeding conveyor belt 42 is wound into a loop by the structure of the front and rear feeding conveyor wheels 41. The inclined feeding conveyor belt 42 can transport the shell B to a high place and reach the longitudinal conveyor belt 3. The further provided partition plate 43 separates the space for accommodating the shell B, and the horizontal conveyor belt for sequentially conveying the shell B can be docked at the input end of the feeding conveyor belt 42 or fed manually; the shell B can reach a high place one by one in an orderly manner and enter the longitudinal conveyor belt 3. The partition plate 43 forms a connecting surface during the transfer of the shell B, that is, the upper end of the partition plate 43 is placed on the input end of the longitudinal conveyor belt 3, which can smoothly transfer the shell B to the longitudinal conveyor belt 3. Thus, a certain space can be set between the longitudinal conveyor belt 3 and the feeding conveyor belt 42, which is beneficial to the disassembly, assembly and maintenance of both. The soft partition plate 43 can also bypass the longitudinal conveyor belt 3 through deformation and reach the lower part of the feeding conveyor belt 42, and the overall operation is smooth.

[0043] The above is only the preferred implementation mode of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions within the idea of the present invention belong to the protection scope of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and retouches should also be regarded as the protection scope of the present invention.
