Intelligent and mechanized carrot harvesting methods still need to be developed. The "Outline of the 14th Five-Year Plan for National Economic and Social Development of the People's Republic of China and the Long-Term Objectives for 2035" proposes a series of instructions to "strengthen the research and development and application of large, medium-sized, intelligent, and complex agricultural machinery", which all advocate that we continue to develop agriculture towards intelligence and digitalization. In order to improve harvesting efficiency and save human resources, the emergence of carrot harvesters is crucial. In order to facilitate the pulling out and cleaning of radishes during harvest, people in this field have designed a root vegetable pulling out and cleaning mechanism. Utility Model Content

A spacing is provided between the active synchronous pulley 23 and the second transmission wheel 45.

[0021] In this embodiment, the conveyor assembly 2 and the stem and leaf cutting assembly 4 are both driven by a transmission shaft 58. The transmission shaft 58 is provided with a stepped surface that effectively prevents the conveyor wheel 23 from falling off the second transmission wheel 45. The upper conveyor assembly 2 provides force for gripping the radish stems and leaves, while the output of the lower stem and leaf cutting assembly is converted into rotating blades 43, which are driven by a drive motor 52. This allows the gripping, soil removal, and stem cutting processes to be performed simultaneously, greatly improving harvesting efficiency.

[0022] The guide and extraction frame assembly 3 comprises two sets of guide aluminum profiles connected to the outside of the conveyor frame 21, arranged in an "eight" shape. The feed wheel 24 is connected to the outside ends of the guide aluminum profiles via fixed blocks. In this embodiment, the inner sides of the guide aluminum profiles are arranged at an angle, and the guide aluminum profiles on both sides form an "eight" shape, which facilitates the guided gathering of radishes.

[0023] In this embodiment, the box body 51 is set with a front opening. By adjusting the distance between the first bevel gear 56 on the transmission rod 54 and the worm gear part, the distance between the two groups of conveying modules can be adjusted, which is convenient for harvesting and conveying root vegetables of different sizes. It has a wide range of applications. The driving motor 52 adopts an M3508 motor. The motor shaft converts the output shaft into a worm part 53 through a coupling. The size of the worm part 53 is 1 module 50 teeth. The transmission rod 54 is arranged between the left and right side plates of the box body 51. The worm part 53 drives the worm gear part 55 on the transmission rod 54 to rotate. The two first bevel gears 55 are coaxially arranged on both sides of the transmission rod 54 in a vertical direction. The second bevel gear 57 is arranged in a horizontal direction and meshes with the first bevel gear 55 to rotate, thereby driving the transmission shaft 58 to rotate. The active synchronous pulley 23 is fixed below the transmission shaft 58, so that the active synchronous pulley 23 drives the conveyor belt 22 to move, thereby realizing the transportation of radishes.

[0024] The soil cleaning assembly includes a soil cleaning brush 6 coaxially connected to the underside of the conveyor wheel 25. The bottom of the guide aluminum profile is connected to the conveyor frame 21 via a connecting plate 7. A limiting guide rod 71 is located at the bottom of the connecting plate 7 and is positioned outside the conveyor belt 22. In this embodiment, the soil cleaning brush 6 is vertically arranged and includes a brush rod and bristles wrapped around it. The rotation of the conveyor wheel drives the brush to rotate and clean the dirt on the radish surface.

[0025] The working process of the present invention is as follows: the present invention is equipped with a walking device to move on the field, the driving motor 52 drives the worm part 53 to rotate, and after the worm gear is engaged, it drives the two sets of first bevel gears 56 to rotate, the second bevel gear 57 is engaged with the first bevel gear 56 to drive the two sets of transmission shafts 58 to rotate, the transmission shaft 58 drives the active synchronous pulley 23 to rotate, the active synchronous pulley 23 drives the conveying wheel 25 and the feeding wheel 24 to rotate through the conveyor belt 22, and the radish is pulled out from the feed port 32 along the guide pulling-out frame group 3 to gather the stems and leaves, and gather the radish leaves scattered around to the middle, which is conducive to the conveyor belt 22 being clamped between the two sets after the radish stems and leaves are gathered at the end of the guide pulling-out frame group 3. The radish is pulled out of the soil by the conveyor belt 22, and the stems and leaves at the end of the radish are transported obliquely upward. The radish is transported obliquely backward along the conveyor frame 21. The soil cleaning brush 6 rotates along the conveyor wheel 25 to brush off the dust on the surface of the radish. At the same time, the transmission shaft 58 drives the active synchronous pulley 23 to rotate and drives the rotating blade 43 to rotate, thereby cutting off the stems and leaves at the end of the radish. The radish body falls, and the stems and leaves continue to move along the conveyor belt 22 for centralized collection, thereby realizing separation of the radish from the stems and leaves. As the walking device moves, the radish is continuously pulled out and cleaned, saving manpower and improving the harvesting efficiency of the radish.

[0026] Finally, it should be emphasized that the above description is not intended to limit the present invention. For those skilled in the art, the present invention may have various changes and modifications. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
