Abstract
Description
Technical Field
[0001] This invention belongs to the field of aquatic organism monitoring technology, and in particular relates to an aquatic organism sampling and sorting device. Background Technology
[0002] The growth of aquatic organisms is not only affected by weather and region, but the most direct influencing factor is water quality. Different aquatic organisms have different water quality requirements. Therefore, before raising aquatic organisms, it is necessary to raise them in different water qualities and sample and compare them. The size of the aquatic organisms can indirectly reflect whether they are suitable for growth in a certain water quality. After sampling, the aquatic organisms need to be sorted, and the aquatic organisms of relatively large sizes need to be separated and the data calculated for comparison (e.g., snails).
[0003] Existing aquatic organism sampling and sorting devices separate cleaning and sorting into two processes, cleaning first and then sorting. This results in low sorting efficiency and only involves a simple rinse of aquatic organisms, which cannot guarantee the cleaning effect and affects subsequent sorting.

Implementation
[0027] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.
[0028] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.
[0029] like Figure 1-6 As shown, an aquatic organism sampling and sorting device according to an embodiment of the present invention includes a support 01, on which a rinsing head 11 is provided, and further includes:
[0030] Sorting component 02, wherein screening component 1 21, screening component 23 and lifting component 20 are slidably connected within the sorting component 02, and elastic component 28 is provided between screening component 1 21 and sorting component 02 and between screening component 23 and sorting component 02, and elastic component 1 24 is provided between lifting component 20 and sorting component 02, and screening component 1 21 and screening component 23 are both in contact with lifting component 20.
[0031] The drive unit 31 has a drive wheel 32 at its output end. The end of the central shaft of the drive wheel 32 is fixedly connected to the center of the sorting unit 02. A driven wheel 33 is meshed with one side of the drive wheel 32. A cam 43 is fixedly connected to the driven wheel 33. A slider 39 is slidably connected inside the cam 43.
[0032] The support 01 is provided with an inclined adjusting member 38. A moving component 30 and a lifting head 51 are slidably connected to the support 01. A cleaning member 36 is fixedly connected to the moving component 30. Both the moving component 30 and the adjusting member 38 are slidably connected to the first sliding head 39. A swing component 501 and a swing component 502 are rotatably connected to the support 01. The swing component 501 and the swing component 502 are meshed together. The swing component 501 is slidably connected to the moving component 30, and the swing component 502 is slidably connected to the lifting head 51.
[0033] The driving component 31 drives the sorting component 02 and the driven wheel 33 to rotate via the driving wheel 32. The sorting component 02 drives the screening component 1 21 and the screening component 23 to rotate. The driven wheel 33 drives the cam 43 to rotate. The cam 43 drives the slide head 39 to slide within the adjusting component 38 by slidingly connecting with the slide head 39. The slide head 39 drives the moving component 30 to reciprocate by slidingly connecting with the moving component 30. The moving component 30 achieves a thorough cleaning effect by driving the cleaning component 36 to reciprocate. The moving component 30 is connected to the swing component 501. The sliding connection drives the first swing component 501 to reciprocate, which in turn drives the second swing component 502 to reciprocate. The second swing component 502, through a sliding connection with the lifting head 51, drives the lifting head 51 to reciprocate up and down. The lifting head 51 drives the lifting component 20 to move upward, which in turn drives the first screening component 21 and the second screening component 23 to move upward. The second elastic component 28 drives the first screening component 21 and the second screening component 23 to move downward. The first screening component 21 and the second screening component 23 achieve thorough cleaning and efficient sorting through a rotary shaking separation method.
[0034] In a preferred embodiment of the invention, the sorting component 02 is a hollow box, the adjusting component 38, the screening component 1 21 and the screening component 23 are all plates, the elastic component 1 24 and the elastic component 2 28 are both springs, the driving component 31 is a motor, and the cleaning component 36 is a cleaning brush; the cam 43 has a cam groove that connects to the slider 1 39. Specifically, the sampled aquatic organisms are poured into the sorting unit 02, and the drive unit 31 and water pump are started. The water pump introduces water into the rinsing head 11, which rinses the aquatic organisms. The cam 43 drives the slide head 39 to slide within the adjusting unit 38 through a sliding connection with the slide head 39. Since the adjusting unit 38 is inclined, the slide head 39 drives the moving component 30 to move back and forth through a sliding connection with the moving component 30, thereby causing the cleaning unit 36 to move back and forth. When the lifting head 51 drives the lifting component 20 to move upward, since both the screening component 21 and the screening component 23 are in contact with the lifting component 20, the lifting component 20 drives the screening component 21 and the screening component 23 to move upward. When component 23 moves upward, and the lifting head 51 moves downward, the lifting component 20 moves downward under the weight of its own weight and the action of elastic component 24. Under the action of elastic component 28, screening component 21 and screening component 23 move downward, so that screening component 21 and screening component 23 rotate and shake up and down at the same time, so that aquatic organisms can be evenly distributed on screening component 21. The reciprocating cleaning component 36 thoroughly cleans the aquatic organisms, and the force generated by shaking can promote the removal of impurities from the aquatic organisms, making it easier for screening component 21 and screening component 23 to sort. The rotation and shaking sorting of screening component 21 and screening component 23 can improve sorting efficiency.
[0035] like Figure 5 As shown, in a preferred embodiment of the present invention, both ends of the screening component 21 and the screening component 23 are fixedly connected with sliding components 27.

[0037] like Figure 1 and Figure 4 As shown, in a preferred embodiment of the present invention, the lifting assembly 20 includes an abutment seat 25, an elastic element 24 is provided between the abutment seat 25 and the sorting component 02, a lifting component 22 is fixedly connected to the abutment seat 25, and a plurality of abutment joints 26 are fixedly connected to the lifting component 22.
[0038] In a preferred embodiment of the invention, the lifting member 22 is a rod that passes through and is slidably connected to the second screening member 23; both the first screening member 21 and the second screening member 23 are movably abutted against by abutment joints 26. When the lifting head 51 moves upward, the lifting head 51 abuts against the abutment seat 25, thereby driving the abutment seat 25 to move upward. The abutment seat 25 drives the abutment joint 26 to move upward through the lifting member 22, and the abutment joint 26 drives the first screening member 21 and the second screening member 23 to move upward. When the lifting head 51 moves downward, the lifting assembly 20 moves downward under the weight of its own weight and the action of the first elastic member 24; under the action of the second elastic member 28, the first screening member 21 and the second screening member 23 move downward, thereby causing the first screening member 21 and the second screening member 23 to shake up and down.
[0039] like Figure 1-3 As shown, in a preferred embodiment of the present invention, the moving component 30 includes a moving part 37, a sliding groove 41 is provided in the moving part 37, a sliding head 39 is slidably connected in the sliding groove 41, a moving part 45 is fixedly connected to the moving part 37, the moving part 45 is slidably disposed in a sliding base 13, the sliding base 13 is fixedly disposed on a fixed base 12, the fixed base 12 is fixedly disposed on a support 01, the sliding head 47 is fixedly connected to the moving part 45, and a cleaning part 36 is fixedly connected to the moving part 45.
[0040] In this embodiment of the invention, preferably, both the first moving part 37 and the second moving part 45 are plates. Specifically, the first sliding head 39 slides within the adjusting part 38, and the first sliding head 39 drives the first moving part 37 to reciprocate by slidingly connecting with the second sliding groove 41. The first moving part 37 drives the cleaning part 36 to reciprocate via the second moving part 45. Since the sorting part 02 is in a rotating state, the cleaning part 36 can thoroughly clean the aquatic organisms within the sorting part 02.
[0041] like Figure 3 As shown, in a preferred embodiment of the present invention, the swing assembly 501 includes a gear 57, which is rotatably mounted on the fixed base 12. A swing member 46 is fixedly connected to the gear 57, and a slide head 47 is slidably connected inside the swing member 46.
[0042] In this embodiment of the invention, preferably, the first oscillating member 46 is a plate; the first oscillating member 46 has a groove that is slidably connected to the second slide head 47. Specifically, the second reciprocating moving member 45 drives the first gear 57 to reciprocate by slidingly connecting with the first oscillating member 46.
[0043] like Figure 1 and Figure 3As shown, in a preferred embodiment of the present invention, the second swing component 502 includes a second gear 53, which meshes with a first gear 57. A second swing member 52 is fixedly connected to the second gear 53. A third slide head 48 is slidably connected inside the second swing member 52. The third slide head 48 is fixedly mounted on the lifting head 51. The lifting head 51 is in movable contact with the bottom wall of the abutment seat 25.
[0044] In this embodiment of the invention, preferably, the second swing member 52 is a plate; the second gear 53 is rotatably mounted on the fixed base 12; a second slide 49 is fixedly connected to the fixed base 12, and a lifting head 51 is slidably connected inside the second slide 49; the second swing member 52 has a groove that is slidably connected to the third slide 48. Specifically, the reciprocating gear 57 drives the second gear 53 to reciprocate, the second gear 53 drives the second swing member 52 to reciprocate, and the second swing member 52 drives the lifting head 51 to reciprocate and lift by sliding it to the third slide 48.
[0045] like Figure 2 and Figure 6 As shown, in a preferred embodiment of the present invention, the adjusting member 38 is provided with a sliding groove 44, the sliding groove 44 is slidably connected to the sliding head 39, a plurality of moving heads 54 are fixedly connected to the adjusting member 38, and an adjusting head 55 is fixedly connected to the end of the adjusting member 38, and a screw 56 is provided in the adjusting head 55.
[0046] In this embodiment of the invention, the driven wheel 33 drives the cam 43 to rotate, and the cam 43 drives the slide head 39 to slide in the slide groove 44 by sliding connection with the slide head 39.
[0047] like Figure 1 and Figure 6 As shown, in a preferred embodiment of the present invention, a positioning member 34 is fixedly connected to the support 01. The positioning member 34 has a plurality of threaded grooves, which are adapted to the screw 56. The inner side of the positioning member 34 is provided with a guide groove 1 58 and a guide groove 2 59. A moving head 54 is slidably connected in both the guide groove 1 58 and the guide groove 2 59. Both the guide groove 1 58 and the guide groove 2 59 are opened on the support 01.
[0048] In this embodiment of the invention, the positioning member 34 is an arc-shaped plate. The shaking intensity of the screening member 21 and the screening member 23 can be adjusted according to the aquatic biomass. Since the vertical displacement of the lifting component 20 is affected by the horizontal displacement of the moving component 30, and the horizontal displacement of the moving component 30 is affected by the inclination of the adjusting member 38 (the angle formed between the moving component 37 and the adjusting member 38 when viewed from above), the inclination of the adjusting member 38 is adjusted. The specific adjustment operation is as follows: the adjusting member 38 is rotated by the adjusting head 55, so that one moving head 54 on the adjusting member 38 moves in the guide groove 58, and the other moving head 54 on the adjusting member 38 moves in the guide groove 59. After adjusting to the specified position, the screw 56 is rotated so that the screw 56 is screwed into the threaded groove (not shown in the figure) at the corresponding position of the positioning member 34, thereby completing the fixing of the adjusting member 38 and thus completing the inclination adjustment of the adjusting member 38.
[0049] The working principle of this invention is:
[0050] The aquatic organism sampling and sorting device pours the sampled aquatic organisms into the sorting component 02, activates the drive component 31 and water pump, and uses the rinsing head 11 to rinse the aquatic organisms. The drive component 31 drives the sorting component 02 and the driven wheel 33 to rotate via the drive wheel 32. The sorting component 02 drives the first screening component 21 and the second screening component 23 to rotate. The driven wheel 33 drives the cam 43 to rotate. The cam 43 drives the first slide head 39 to slide within the adjusting component 38. The first slide head 39 drives the first moving component 37 to reciprocate by slidingly connecting with the second sliding groove 41. The first moving component 37 drives the second moving component 45 to reciprocate, and the reciprocating cleaning component 36 thoroughly cleans the aquatic organisms. The second moving component 45 is connected to the swing component 41. 6 drives gear 1 57 to rotate reciprocally. Gear 1 57 drives oscillating component 2 52 to rotate reciprocally through gear 2 53, which in turn drives lifting head 51 to move up and down reciprocally. The upward-moving lifting head 51 drives screening component 1 21 and screening component 2 23 to move up through lifting component 20. When lifting head 51 moves down, screening component 1 21 and screening component 2 23 move down under the action of elastic component 28. Therefore, screening component 1 21 and screening component 2 23 rotate and shake up and down at the same time. Finally, large-diameter aquatic organisms are trapped on screening component 1 21 and small-diameter aquatic organisms are trapped on screening component 2 23. Open the door of sorting component 02 to take out the sorted aquatic organisms. Impurities and sewage are discharged through the sewage pipe.
[0051] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the present invention, and these should also be considered within the scope of protection of the present invention. These modifications and improvements will not affect the effectiveness of the implementation of the present invention or the practicality of the patent.
