Reviewer 1 Report
It is an interesting research and the content is also relatively rich. In general, this paper is well organized. The quality of the paper can be further improved by addressing the following problems.
1. The contributions of your work should be highlighted.
2. In line 98, Full spelling for “R＆D” should be given.
3.The title “Materials and Methods” should be placed after the “Introduction” Section.
4. Figure 8 is unclear.
5. Is the laver harvesting device designed to be automatic or manually controlled? Its control system should be briefly mentioned in manuscript, similar to the following literature: https://doi.org/10.3390/agriculture13010124.
6. In the conclusion section, the authors should add their future perspectives about this topic.
7. Please check the reference format and modify it.
8. The language of the manuscript needs polishing.

Reviewer 2 Report
1. A rigid-flexible coupling model related to the interaction between the cutting mechanism and the laver was constructed based on ANSYS/LS-DYNA. The flexible model of laver is the key to the coupling model. However, there is no calibration process for laver model in this paper.
2. In Figure 14, under three test (No.1, 2, and 3), the net recovery rate of laver increases first and then remains stable with the increase of the rotation speed. However, it is not enough to support the change trend analyzed in this paper by the three data points. The same problem occurs in Fig. 15 and 17.
3. The index of the simulation test is the cutting force. The index of bench test is the net recovery rate and the loss rate. The connection between them must be made clear. 4. The annotation C and D in Figure 5 are inaccurate.
5. Different components in figure should be labeled differently. The annotations in Figure 4 and Figure 5 should be different, such A, B.
6. The formula (11) described in section 3.1 of the article is incorrectly stated.
7. The annotated part of Figure 5 in Section 3.2 of the article, C and D do not match with the illustration.
8. In section 5.3 of the article, there are errors in the writing of the third-level title.
9. At the conclusion of the article, there are errors in the first-level title writing.
10. The title mentions ANSYS/LS-DYNA simulation, but the analysis content of ANSYS/LS-DYNA simulation in the article is too simple, and the flexible body part is not reflected enough in the rigid-flexible model.
11. Summary and conclusion of the article are too repetitive and the language is too cumbersome.
12. Insufficient innovation of articles.

Reviewer 3 Report
The manuscript addresses the problems such as low net harvesting rate, high loss rate, and uneven stubble height during the harvest of laver, and proposes a sectional hob-type harvesting device. By using ANSYS/LS-DYNA simulation analysis and the Box-Behnken design method, the optimal operating parameters of the harvesting device were determined. The manuscript study is beneficial to improve the development of harvesting for the laver and has a better reference value for the design and optimization of harvesting devices for the laver and other similar crops. Suggestions for further revisions.
(1) In chapter“4.2. Response Surface Test Design” of this paper, The Inclination Angle (A), Extension Length (B), Traveling Speed (C) and Rotation Speed (D) was selected as the test factor. What is the way to determine the range of values？
(2) In lines 207 through 218, whether the Conditions that laver would be cut off was the author citing the relevant theory. If other theories were cited, please mark the relevant references.
(3) In chapter “4.1. Model Establishment and Simulation Results”, simulation model building and parameter setting should be more specific.
(4) The analysis of the response surface figure should be combined with the actual working principle.
(5) Equation (5) in chapter "3.1" is the same as equation (8).
