Specifically, as in the present embodiment, the back-opening descaler further includes an adjusting unit 82, the adjusting unit 82 includes a lead screw 821 and a hand wheel 822, wherein, the end part of the first roller 811 of each group of the conveyer belts 81 is provided with a first connecting block 8111, the lead screw 821 is rotatablely arranged on the frame around the axis of the lead screw 821, the axis of the lead screw 821 is parallel to the axial direction of the descaling wheel, two thread sections with opposite screwing directions are arranged on the lead screw 821, and a segment of the threaded section is threadedly coupled to a first connection block 8111, such that when the lead screw 821 is rotated, the screw 821 can drive the two first roller shafts 811 to move towards or away from each other along the axial direction of the screw 821 through two thread sections on the screw 821, and then reach the purpose of adjusting the wheel base between two first roller 811 for two sets of conveyer belts 81 cooperation can be transported different varieties and/or not equidimension fishes, and guarantee the reliability of opening back unit 83 and descaler unit 84 processing. The hand wheel 822 is installed at the end of the lead screw 821, and the lead screw 821 can rotate without other external tools by arranging the hand wheel 822, so that the distance between the two groups of conveying belts 81 can be adjusted more conveniently.

Finally, it should be emphasized that the above-described embodiments are merely preferred examples of the present invention, and are not intended to limit the invention, as those skilled in the art will appreciate that various changes and modifications may be made, and any and all modifications, equivalents, and improvements made, while remaining within the spirit and principles of the present invention, are intended to be included within the scope of the present invention.
