Description

Technical Field

[0001] The present invention relates to the technical field of shellfish seed screening, and in particular to an automatic seedling screening device and an automatic seedling screening method. Background Art

[0002] Spat refers to the juveniles of molluscs, such as those of Manila clams, that have just settled or are living on the bottom of the water. During spat culture, such as that of the Manila clam, screening is required to select the spat of the desired size to meet the needs of the production process.

[0003] In the existing technology, there are currently two main screening methods for the specifications of clams such as Manila clams: manual screening and machine screening. The advantage of manual screening is that it can sort clams of different specifications, but the disadvantage is that it consumes a lot of manual labor and is extremely inefficient when large quantities of screening are required. The advantage of machine screening is high screening efficiency and labor savings, but the disadvantage is that the specifications of clams that can be screened are limited and the screen is easily clogged, which affects the screening effect.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] The purpose of the present invention is to provide an automatic seedling screening device and an automatic seedling screening method to solve the problems existing in the prior art, realize the screening of shellfish seedlings of various specifications, and improve the efficiency and screening effect of shellfish seedlings.

[0025] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] Example 1

[0027] like Figure 1-Figure 3As shown, this embodiment provides an automatic seedling screening device, which is mainly used for screening shellfish seeds taking Manila clam as an example. The automatic seedling screening device includes a screening element, a flushing element, a collecting element and a derivation element. The screening element is used to pass the shellfish seeds to be screened, so as to screen the shellfish seeds through the screening element, so as to obtain shellfish seeds of the required specifications (that is, shellfish seeds with a size smaller than the sieve hole diameter of the screening element). The collecting element is located below the screening element, and the collecting element is used to collect small-sized shellfish seeds screened by the screening element. The flushing element is located on one side of the screening element, and the flushing element can spray water to the screening element, thereby flushing the surface of the screening element to avoid water on the screening element. The sieve holes are blocked and the screening effect is affected. The screening element includes a conveying part and a screening part. The derivation element is installed at one end of the conveying part. The screening part is used to screen the shellfish of the required specifications, and then the shellfish with a size greater than or equal to the sieve hole diameter of the screening part will be retained in the screening part, and the shellfish with a size smaller than the sieve hole diameter of the screening part will be screened out. The screening part can be replaced, and then by replacing the screening part with different apertures, shellfish of different specifications can be screened out. The conveying part is used to convey the shellfish in the screening part to the derivation element, and the derivation element is used to derivate the shellfish of the required specifications in the screening part, so as to realize the automatic collection of shellfish of the required specifications, save labor and improve the efficiency of shellfish screening.

[0028] As a specific implementation scheme in this embodiment, the conveying part is a spiral conveying auger 5, which can realize the conveying of the shellfish seedlings in the screening part to the derivation element by rotating the conveying part. The screening part includes a screen drum 4 and two connecting ends. The spiral conveying auger 5 is installed in the screen drum 4, and the spiral conveying auger 5 and the screen drum 4 can rotate synchronously. The two connecting ends can be detachably connected to the two ends of the screen drum 4, thereby facilitating the replacement of the screen drum 4. The mesh number of the screen drum 4 can be 16 mesh, 20 mesh, 24 mesh, 30 mesh or 60 mesh. Preferably, the two ends of the sieve drum 4 are connected to the two connecting ends by rivets. Among the two connecting ends, one of the connecting ends is the first connecting end 3, which is used to introduce the shellfish to be screened into the sieve drum 4, that is, the first connecting end 3 corresponds to the inlet of the sieve drum 4, and the other connecting end is the second connecting end 6, which is arranged close to the outlet element, that is, the second connecting end 6 corresponds to the outlet of the sieve drum 4, and the second connecting end 6 is used to guide the shellfish remaining in the sieve drum 4 through the outlet element to achieve the collection of shellfish of the required specifications. In this embodiment, for the specific structural design of the conveying part and the screening part, those skilled in the art may also choose other methods as long as they can meet the above-mentioned usage requirements.

[0029] As a specific implementation scheme in this embodiment, this embodiment also includes a driving element, which is arranged near the second connecting end 6, and the power output end of the driving element is connected to the second connecting end 6. The driving element can drive the conveying part and the screening part to rotate, so as to achieve effective screening of the shellfish seedlings as the screening part rotates. At the same time, as the conveying part rotates, the shellfish seedlings are conveyed to the first connecting end 2, thereby improving the shellfish seedling screening effect and screening efficiency, and avoiding the accumulation of shellfish seedlings in the screen cylinder 4 affecting the smooth screening of the shellfish seedlings.

[0030] As a specific implementation scheme in this embodiment, the outlet element includes a flow guide cover 2 and a flow guide bag 12. The flow guide cover 2 is installed below the first connecting end 3, so that the mussels in the screen drum 4 fall into the flow guide cover 2 after being guided through the first connecting end 3. From top to bottom, the opening of the flow guide cover 2 gradually decreases, which makes it easier to guide the mussels through the flow guide cover 2 and achieve the collection of mussels. The two ends of the flow guide bag 12 are open, and one end of the flow guide bag 12 is connected to and communicates with the lower end of the flow guide cover 2, so that the mussels can be guided out through the flow guide bag 12. Among them, the flow guide bag 12 can also be replaced with other structures, such as diversion structures such as diversion pipes and diversion slopes, as long as the smooth guidance of the mussels can be achieved.

[0031] As a specific implementation scheme in this embodiment, the driving element is a driving motor 1, and the output shaft of the driving motor 1 can pass through the outlet cover and be connected to the second connecting end 6. Those skilled in the art can also choose other driving methods according to actual needs.

[0032] As a specific implementation scheme in this embodiment, this embodiment also includes a containing element 7, which is used to place the shellfish to be screened in the containing element 7 to facilitate continuous screening of the shellfish, and the shellfish in the containing element 7 can be replenished at any time. The containing element 7 is arranged above the second connecting end 6, thereby ensuring that the shellfish in the containing element 7 can enter the sieve cylinder 4 through the second connecting end 6. The containing element 7 includes a containing box and a filter screen 14. A seedling outlet 15 is provided on the bottom surface of the containing box. The filter screen 14 is installed in the containing box, and the shellfish in the containing box will enter the second connecting end 6 and the sieve cylinder 4 through the seedling outlet 15 after being filtered by the filter screen 14, and then the shellfish are preliminarily filtered by the filter screen 14 to filter out shellfish that are larger than the required specifications. Preferably, in order to ensure that the mussels below the filter screen 14 can smoothly pass through the seedling outlet 15 and enter the sieve drum 4, the bottom surface of the containing box can be arranged at an angle, and the seedling outlet 15 can be located at the lowest point of the bottom surface of the containing box, to ensure that the water and mussels between the bottom surface of the containing box and the filter screen 14 can move toward the seedling outlet 15 under the action of gravity, so as to be easily discharged through the seedling outlet 15.

[0033] As a specific implementation scheme in this embodiment, the flushing element is a flushing pipe 10, which extends along the length direction of the screening part. A plurality of flushing holes 13 are provided on the flushing pipe 10. The plurality of flushing holes 13 are arranged in sequence along the length direction of the flushing pipe 10, and the water outlet direction of each flushing hole 13 is toward the screening part, thereby ensuring that the water sprayed from the flushing hole 13 can act on the screening part. At the same time, the setting of the plurality of flushing holes 13 ensures that all positions on the screening part can be flushed, thereby improving the flushing effect and further improving the screening effect and screening efficiency.

[0034] As a specific implementation scheme of this embodiment, two flushing pipes 10 are provided, and the two flushing pipes 10 are respectively located on both sides of the screening part, and the two flushing pipes 10 are symmetrically arranged along the axis of the screening part. As an example, the flushing pipes 10 are PVC pipes.

[0035] As a specific implementation scheme in this embodiment, the collecting element is a collecting box 9, the upper end of the collecting box 9 is open, and the screening element is arranged at the upper end opening of the collecting box 9 to ensure that the collecting box 9 can smoothly collect the shellfish and water screened by the screening element. An outlet pipe 11 is provided on the side wall of the collecting box 9. The outlet pipe 11 is used to discharge the water and shellfish in the collecting box 9 to avoid the water level in the collecting box 9 being too high and causing the shellfish to overflow through the upper end opening of the collecting box 9. A valve is connected to the outlet pipe 11 to control whether the water in the outlet pipe 11 flows. In actual application, technical personnel in this field can control the opening and closing of the valve in real time according to the water level in the collecting box 9 to avoid the water and shellfish in the collecting box 9 from overflowing. At the same time, when the valve is opened and the water in the collecting box 9 is discharged through the outlet pipe 11, other filtering structures with smaller sieve holes can be set at the lower end of the outlet pipe 11 to further separate the shellfish from the water.

[0036] As a specific implementation scheme of this embodiment, this embodiment also includes a bracket 8, which is used to support and elevate other structures.

[0037] Example 2

[0038] The present embodiment provides an automatic seedling screening method, using the automatic seedling screening device in the first embodiment, including: pouring the shellfish to be screened into the interior of the containing element 7, the shellfish undergoing primary filtration through the filter 14, so that the shellfish with a size greater than or equal to the aperture of the filter 14 remain at the upper end of the filter 14, and the shellfish with a size smaller than the aperture of the filter 14 are screened out, and then the screened shellfish enter the screening element through the seedling outlet 15. As the conveying part and the screening part rotate, the shellfish of the required specifications remain in the screening part, and the shellfish smaller than the required specifications fall into the collecting element. When it is necessary to screen out shellfish of different specifications, the screen of the screening part can be directly replaced. The method is easy to use and has a wide range of applications. At the same time, during the screening process, the conveying part drives the shellfish of the required specifications to gradually move toward the direction close to the outlet element, and finally the shellfish of the required specifications are discharged through the outlet element. When it is necessary to discharge the water in the collecting element, the valve on the collecting element is opened to discharge the water in the collecting element through the outlet pipe 11 to prevent the water in the collecting element from overflowing through the upper end of the collecting element with the shellfish.

[0039] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only intended to help understand the method and core concept of the present invention. At the same time, those skilled in the art will find that the specific implementation methods and application scopes may vary based on the concept of the present invention. In summary, the contents of this specification should not be construed as limiting the present invention.
