Reviewer 2 Report
Comments and Suggestions for Authors
- The explanation of the working principle is unclear, and there is a lack of an overall schematic diagram and corresponding working principle.
- When dividing the grid, what size of grid should be chosen for analysis, and why?
- What are the specific indicators for the non-uniformity of airflow distribution?
- During operation, will the tea collection tube vibrate? If there is vibration, has the impact of vibration on the tea collection tube been considered?
- Line 216's (y1) should be changed to (Y1); moreover, there is inconsistency in the case of y1y2 throughout the text, please unify y1y2 to Y1Y2.
- The formula format on line 229 is incorrect, it needs to be calibrated.
- In Figure 5a should be changed to In figure 5(a), there are many such issues in the article, please correct them one by one.
- The text content in Figure 5 and Figure 6 is too small, it is suggested to modify and enlarge; also, the labeling format in the two figures is not consistent, it is suggested to unify to (a)(b)(c).
- The numerical annotations and references in the related simulation diagrams are not clear, it is suggested to redraw the diagrams in post-processing.
- The analysis of Figure 10 on line 325 should correspond to Figure 9, please check.
- There are too few references, it is recommended to increase them.

Reviewer 3 Report
Comments and Suggestions for Authors
The article comprehensively applies a combination of numerical simulation based on Fluent software and experimental testing to study the low damage collection problem of tea. The research results have certain reference value for improving tea picking techniques. However, there are still some issues that need to be addressed.
1. Literature 13 in the introduction is improperly quoted and does not link up with the context, so it is suggested to delete.
2. Line 136, "According to equation (3)" does not correspond to the sequence number of equation (1). It is suggested to modify it.
3. The Fig.10 is unclear, it is suggested to enlarge the difference.
4. In the field experiment, the test methods and materials are not introduced. It is suggested to add the equipment selection, operation process and so on.
5. Would the environmental factors (wind speed, humidity and so on) affect the results of the field experiment? Please explain.
6. In this paper, only three factors affecting the external structure of the collecting pipeline are selected, why not select other factors to optimize? Please explain.

Reviewer 4 Report
Comments and Suggestions for Authors
To address the challenges of missed and disorderly picking in tea harvesters, the key parameters and reasonable value range affecting the airflow velocity in the leaf collecting pipeline on the tea harvester were determined. The operational effectiveness of this device has been verified through the field trials, demonstrating a certain degree of innovation and engineering application value. However, there are still some issues that need to be addressed.
(1) The response surface model in Figures 5 and 6 is not clear enough.
(2) The B unit in Table 1 should be removed and the full text should be unified.
(3) In lines 95-96, the divided mesh is imported into Fluent for the numerical simulation analysis, and it is recommended to add the meshing pictures.
(4) The references may not reflect the latest research progress. It is suggested to update the relevant literature published in the past three years, which is to ensure the forefront and accuracy of the research.
(5) Figure 11 should mark the main components, which is to facilitate the understanding of the overall layout.
(6) Check the format of line 251, such as X12, X22, X32. Some letters require superscripts.
