Description

Technical Field

[0001] This utility model relates to the field of toad breeding technology, and in particular to a toad size grading device. Background Technology

[0002] Toad farming requires grading toads of different sizes. Manual grading is labor-intensive and time-consuming, especially on a large scale, making it difficult to meet the demands of batch processing. Farmers have to repeat the selection process for extended periods, which is not only physically demanding but also prone to fatigue, leading to a decrease in grading speed and severely hindering the overall efficiency of the grading work. While automated grading devices utilize the toads' tendency to move and burrow to filter toads of different sizes through perforations, most grading devices lack guidance mechanisms for the toads. This results in toads having little desire to move and remaining stationary inside the device. Using external objects to drive the toads risks injuring them and makes it difficult to control their movement, further impacting the efficiency of the grading process. Utility Model Content

[0003] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide a toad grading device that increases the activity of toads in the device, reduces the damage to toads during the grading process, and improves the efficiency of toad grading.

[0004] This utility model also provides a toad grading device with the aforementioned specifications, comprising: a box body, a cover plate rotatably connected to the upper surface of the box body, and three transparent boxes (No. 1, No. 2, and No. 3) arranged inside the box body. Each of the three transparent boxes has screening holes on its surface. A long plate is slidably connected inside each of the three transparent boxes. A yellow light strip and a white light strip are fixedly connected to the lower surface of the long plate and the right wall of the box body, respectively. A battery is fixedly connected to the upper surface of the long plate. Openings are provided on both the front and rear surfaces of the box body. An automatic telescopic rod is fixedly connected to the front surface of the box body. A long rod is fixedly connected to the output end of the automatic telescopic rod. Multiple side plates are provided on the surface of the long rod, and the side plates pass through the openings and are fixedly connected to the long plate. This device increases the activity of the toads inside, improves the efficiency of toad grading, and reduces the risk of injury to the toads.

[0005] According to the toad grading device of this utility model, there are three covers, which respectively enclose transparent boxes No. 1, No. 2, and No. 3. This improves the convenience of using the covers.

[0006] According to the toad grading device of this utility model, both the second and third transparent boxes have baffles slidably connected to their left inner walls, with the upper ends of the baffles penetrating the cover plate to prevent the toads from returning.

[0007] According to the toad grading device of this utility model, the side plates on the front surface of the long plate in both the No. 2 and No. 3 transparent boxes are provided with through holes, the diameter of which is larger than the diameter of the long rod. This prevents the long rod from being obstructed from sliding.

[0008] According to the toad size grading device of this utility model, a plurality of limiting baffles and silicone baffles are fixedly connected to the right end of the long rod, and the diameter of the limiting baffles is larger than the diameter of the through hole. This ensures that the long rod drives all the side plates to move.

[0009] According to the toad grading device of this utility model, a limiting member is provided between the rear surface of the box and the long plate. The limiting member consists of a round rod and multiple connecting pieces, which restricts the range of motion of the long plate.

[0010] According to the toad-specification grading device of this utility model, the round rod is fixedly connected to the rear surface of the box, the connecting piece is fixedly connected to the rear surface of the long plate, and the connecting piece is penetrated by the round rod. This improves the convenience of maintenance and limit components.

[0011] According to the present invention, a toad grading device is provided, wherein the box body is made of opaque material, and the diameter of the screening holes on the right wall of the first transparent box and the left wall of the second transparent box is larger than the diameter of the screening holes on the right wall of the second transparent box and the left wall of the third transparent box. This improves the ease of use of the device.

[0012] Beneficial effects:

[0013] The toad grading device of this technical solution utilizes the toad's phototaxis in dark environments through an automatic telescopic rod, a long rod, a side plate, a yellow light strip, and a white light. It increases the toad's activity by using a repeatedly sliding right-handed moving light source and a fixed light source, guiding the toad to move directionally through the screening holes and improving the efficiency of the toad grading process. The independently flip-open cover improves the convenience of collecting the graded toads. Attached Figure Description

[0021] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0022] Reference Figure 1-4 This utility model discloses a toad grading device, comprising: a box 1 made of opaque material; a cover 10 rotatably connected to the upper surface of the box 1; the box 1 and the cover 10 cooperate to provide darkness for the toads; the box 1 contains a first transparent box 12, a second transparent box 13, and a third transparent box 14; and three covers 10, which respectively close the first transparent box 12, the second transparent box 13, and the third transparent box 14; and baffles 11 slidably connected to the left inner walls of the second transparent box 13 and the third transparent box 14. The upper end of the cover plate 10 has screening holes 21 on the surface of transparent boxes 12, 13, and 14. The diameter of the screening holes 21 on the right wall of transparent box 12 and the left wall of transparent box 13 is larger than that on the right wall of transparent box 13 and the left wall of transparent box 14. The screening holes 21 are used to provide passage conditions for toads of different sizes. The diameter of the screening holes 21 on the right wall of transparent box 12 and the left wall of transparent box 13 is the same, and the diameter of the screening holes 21 on the right wall of transparent box 13 and the left wall of transparent box 14 is the same.

[0023] Specifically, when using the device, open the cover 10 of the first transparent box 12, put the toad into the first transparent box 12, and close the first transparent box 12 again with the cover 10. The interior space of the box 1 is in a dark environment without light, and the toad is attracted to move to the right. Smaller toads pass through the screening hole 21.

[0024] The interiors of transparent boxes 12, 13, and 14 are all slidably connected to long plates 5. The lower surface of the long plate 5 is fixedly connected to the right wall of the box 1 with a yellow light strip 20 and a white light 15, respectively. The upper surface of the long plate 5 is fixedly connected to a battery 16. The yellow light strip 20 and the white light 15 are used to attract toads in dark environments. Both the front and rear surfaces of the box 1 are provided with openings 2, which are used to provide conditions for the long plate 5 to be affected by external forces. An automatic telescopic rod 3 is fixedly connected to the front surface of the box 1. The output end of the automatic telescopic rod 3 is fixedly connected to a long rod 4. The surface of the long rod 4 is provided with multiple side plates 6. The side plates 6 pass through the openings 2 and are fixedly connected to the long plate 5. The automatic telescopic rod 3 cooperates with the long rod 4 and the side plates 6 to provide the power for the long plate 5 to slide left and right.

[0025] Specifically, after the box 1 is closed with the cover plate 10, the white light 15 and the yellow light bar 20 are turned on. The white light 15 directly attracts the toad to move to the right. The toad that does not notice the white light 15 can be attracted by the beam of light emitted by the yellow light bar 20 on the bottom of the box. The automatic telescopic rod 3 extends and pushes the long rod 4 to move to the right. The long plate 5 is integrated with the long rod 4 through the side plate 6. The long plate 5 slides to the right at the same time, so that the beam of light emitted by the yellow light bar 20 is close to the screening hole 21.

[0026] Both the side plates 6 on the front surface of the long plate 5 in transparent box 13 and transparent box 14 have through holes 7. The diameter of the through holes 7 is larger than the diameter of the long rod 4. The through holes 7 provide the long rod 4 with the condition to pass through the side plate 6. The right end of the long rod 4 is fixedly connected to multiple limiting baffles 8 and silicone baffles 9. The diameter of the limiting baffles 8 is larger than the diameter of the through holes 7. The limiting baffles 8 and silicone baffles 9 cooperate to provide the long rod 4 with the condition to apply a pushing force to the side plate 6. A limiting member 17 is provided between the rear surface of the box 1 and the long plate 5. The limiting member 17 consists of a round rod 19 and multiple connecting pieces 18. The round rod 19 is fixedly connected to the rear surface of the box 1, and the connecting pieces 18 are fixedly connected to the rear surface of the long plate 5. The connecting pieces 18 are penetrated by the round rod 19. The limiting member 17 is used to limit the range of motion of the long plate 5.

[0027] Specifically, since the lengths of the three transparent boxes 12, 13, and 14 are different, the movable range of the long plate 5 inside the transparent box 12 is greater than that of the long plates 5 in the transparent boxes 13 and 14. As the automatic telescopic rod 3 continuously pushes the long rod 4 to the right, the three long plates 5 move to the right simultaneously. At this time, the silicone baffle 9 restricts the movable range of the side plate 6. After the long plates 5 in the transparent boxes 13 and 14 can no longer move, the side plate 6 is still pushed to the right by the long rod 4. After the pushing force exceeds the deformation limit of the silicone, the deformed silicone baffle 9 passes through the through hole 7. At this time, the rear end of the long rod 4 is in a state of directly passing through the through hole 7 on the surface of the side plate 6, and no longer applies a pushing force to the side plate 6. During the pull-back process, the pulling force also causes the silicone baffle 9 to pass through the through hole 7, thereby restoring the silicone baffle 9 to the left side of the side plate 6.

[0028] Working principle: Place the toad directly into the first transparent box 12. After sealing the first transparent box 12 with the cover plate 10, the inside of the box 1 is in a dark environment. At this time, turn on the yellow light bar 20 and the white light 15 to attract the toad. Then, the automatic telescopic rod 3 extends and pushes the long rod 4 to move to the right, thereby causing the long plate 5 to move horizontally to the right. At this time, the light projected by the yellow light bar 20 on the bottom of the transparent box moves towards the screening hole 21. This, together with the white light 15, attracts the toad to move to the right and pass through the screening hole 21. During the repeated extension of the automatic telescopic rod 3, it causes the long plate 5 to slide left and right in the transparent box, attracting the toad's attention and causing the toad to move to the right and crawl through the screening hole 21. After a period of time, press down the baffle 11 to block the passage that the toad can crawl through. Finally, open the cover plate 10 from left to right to take out the toads in the three transparent boxes.

[0029] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
