[0057] In embodiments 1-9, it should be noted that the peanut harvester 1 is generally composed of a hand tractor and a peanut stalk harvesting cutter, and the hand tractor needs to be started by manually rocking the lever. Therefore, in order to avoid interference from the movable beam 19 beside the hand tractor when starting the hand tractor, we need to disassemble the movable beam 19 before the stalk supporting operation, and then install the movable beam 19 on the fixed beam 18 when the hand tractor is started.

[0058] The use principle of the stalk supporting device suitable for the peanut harvester is as follows:

[0059] (1) Installation of the stalk supporting device:

[0060] First, the rear end fixed frame is fixed on the front end of the peanut harvester 1 to ensure firm fixation, and then the fixed beam 18 of the front end movable frame is fixed on the peanut harvester 1 by the bolt fastener. After starting the hand tractor, the adjusting end of the movable beam 19 is abutted on the inner wall of the fixed beam 18 by the bolt fastener, thereby completing the installation of the front end movable frame. At this time, according to the growth conditions of the peanut stalks and the soil conditions, the position of the inner adjusting rod 11 in the outer fixed rod 10 is adjusted and fixed by the bolt fastener, so as to adjust the working height of the stalk supporting rod and ensure that the stalk supporting rod can effectively contact the peanut stalks.

[0061] (2) Stalk supporting operation stage:

[0062] After ensuring that all components are firmly installed and adjusted, the peanut harvester 1 is started to begin advancing, and the operator moves the control lever 5 to the starting end 13 of the clutch groove. During this period, the clutch pull rod 4 is dragged, thereby driving the stalk supporting pull rod 2 to swing through the swing connecting plate 3 and the pull rod connecting shaft 9, and driving the connecting rod 16 and the stalk supporting rod to swing around the first hinge point 7, so that the stalk supporting rod approaches the peanut stalks on the soil layer. When supporting the stalks, the front end of the stalk supporting rod is lifted at a certain angle due to the guidance of the stalk supporting rod when contacting the peanut stalks in the horizontal state, which can meet the conditions for being harvested by the peanut harvester 1, thereby achieving the effect of supporting the stalks.

[0063] (3) Stalk supporting end stage:

[0064] When the harvesting operation of a peanut field is completed, the peanut harvester 1 is stopped and the operator holds the operating lever 5 and moves it to the end of the stroke at the disengaging slot 14, the movable beam 19 of the front movable frame is disengaged from the fixed beam 18, and the whole peanut supporting device is removed from the peanut harvester 1.
