Design and Parameters Optimization of a Provoke-Suction Type Harvester for Ground Jujube Fruit

Round 1

Reviewer 1 Report

This is a very good manuscript. Below are some comments for improvement. 

• The title is clear and to the point
• Abstract, Line 13: Twisted statement, please re-word. 
• The objective statement is clear and valid. The abstract is very well organized and written. 
• Line 31: Error reference. Please double-check for similar flaws.

• Introduction, Opening paragraph: You need to provide 2-3 lines of background about robotic harvesting. Please consider adding the following motivational statements and background: "Traditional harvesting of fruits is a labor-intensive......Modering agriculture is shifting from tedious manual harvesting to a continuously automated operation..[REF1,REF2]"

Figure 1: Please provide a general caption describing the figure before mentioning the labels. 

Line 105, 175, 183, 183,247 ...: where, please double check for similar flaws.

Figure 2: Can you provide a color version of this figure? 

Line 186: Did you mean "Design of the cleaning device"?

Table 4, Table 5, Table 6 I don't think you need to provide such detailed results of statistical analysis. It is not of interest for many readers the degree-of-freedom, and F-value. Please consider removing these tables...or at least provide a summary of all three tables as one Table. Again you don't need to report F-vaues, etc. You can simply highlight the core findings in your text.

Reviewer 2 Report

The present paper introduces an interesting technique for harvesting Jujube fruit through Provoke-suction. 

The machine is well detailed, and the papers present a good description of the harvesting method, achieving an excellent working efficiency. 

The authors must improve the general English of the paper. I suggest the usage of orthography software (e.g. Grammarly, InstaText etc).

I would like to see a wider literature review. There are only a few references in the introduction. There is not even a related work section. So please, improve the literature review.
