The gear box 6 drives the shovel cutting tool structure to vibrate back and forth when harvesting leafy vegetables, thereby effectively cutting the roots of the leafy vegetables.

[0086] The height and position of the cutting tool can also be changed when the crawler structure is adjusted.

[0087] Secondly, it is explained that a collecting structure is also installed at the rear end of the frame 1, and the collecting structure cooperates with the upper conveyor belt 51. The leafy vegetables clamped and transported by the upper conveyor belt 51 fall into the collecting structure to collect the leafy vegetables.

[0088] When the utility model is used and moves, the motor 68 drives the reduction box 67 to rotate, the reduction box 67 drives the gear box 6 to rotate, the gear box 6 drives the track drive shaft 71 to rotate, the track drive shaft 71 drives the track wheel 72 to rotate, the track wheel 72 drives the track 76 to rotate, and then the equipment moves.

[0089] During harvesting, the motor 68 drives the reduction box 67 to rotate, the reduction box 67 drives the gear box 6 to rotate, the gear box 6 drives the two driving rods 63 to rotate, the driving rod 63 drives the linkage rod 65 to rotate through the bevel gear set 64, the linkage rod 65 drives the four gears 66 to rotate, and then the gear 66 drives the lower conveying wheel 3 to rotate; the lower conveying wheel 3 drives the lower conveyor belt 31 to rotate, and the two adjacent lower conveyor belts 31 clamp the leafy vegetables and transport them upward; the lower conveying wheel 3 drives the middle conveyor belt 41 and the driving wheel 46 to rotate, the driving wheel 46 drives the conveying rope 49 to rotate, the leafy vegetables transported by the lower conveyor belt 31 enter between the middle conveyor belt 41 and the conveying rope 49, the middle conveyor belt 41 and the conveying rope 49 clamp the leafy vegetables and continue to transport them upward; the middle driven wheel 43 drives the upper conveying wheel 5 to rotate, the upper conveying wheel 5 drives the upper conveyor belt 51 to rotate, the upper conveyor belt 51 clamps the leafy vegetables and transports them upward, and then falls into the collection structure.

[0090] When adjusting the angle of the crawler wheel, the staff pulls the pull rod, the pull rod drives the sleeve 81 to move, the sleeve 81 pulls the arc plate 83 to move, the arc plate 83 rotates around the second cross bar 84 as the axis, and the bottom of the arc plate 83 rotates forward; when the bottom of the arc plate 83 rotates forward, it moves the pulling plate 87 forward; the bottom of the pulling plate 87 moves forward, the pulling plate 87 is limited by the second adjusting rod, and the pulling plate 87 rotates around the second adjusting rod as the axis, and the top of the pulling plate 87 drives the rotating plate 73 to rotate backward, and the rotating plate 73 rotates with the crawler 76, thereby adjusting the horizontal angle of the two crawler tracks 76.

[0091] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
