[0002] When planting Custard Apple, the seedlings need to be cultivated and shaped, and then transported to the planting area for planting. After planting, pruning is required every year to maintain the tree shape and promote flower bud differentiation. Pruning is generally carried out twice a year, once in winter (January-March) and once in summer (June-September). The purpose of pruning is to reduce the tree width, dwarf the plant, and tidy up the tree shape. Winter pruning requires artificial forced leaf fall of the entire plant to promote flower bud differentiation and make the growth neat. After cultivation and shaping, transplant to the target planting area. During transportation, damage to the seedlings should be reduced to avoid affecting the survival rate of the seedlings.

[0057] like Figure 7 As shown, the folding member includes a support rod 36 and an adjustment seat 37, one end of the support rod 36 is hinged to the bottom of the adjustment seat 37, and one end of the support rod 36 away from the adjustment seat 37 is hinged to the leg frame 34, and an adjustment slot 38 for sliding the adjustment seat 37 is provided at the bottom of the transplanting box 32, and an adjustment member for adjusting the position of the adjustment seat 37 in the adjustment slot 38 is installed on the transplanting box 32;

[0058] The adjusting seat 37 slides in the adjusting slot 38 , and can drive the support rod 36 to adjust the leg frame 34 to rotate around the rotating seat 41 to adjust the angle, so as to realize the folding and unfolding of the leg frame 34 .

[0059] like Figure 6 and 7 As shown, the adjustment member includes a slide bar 39, one end of which is fixedly connected to a knob 40 arranged on the outer wall of the transplanting box 32, an outer wall of the slide bar 39 near the knob 40 is provided with an external thread, and an end of the slide bar 39 near the knob 40 is provided with a threaded hole matching the external thread, an adjustment seat 37 arranged near the side of the knob 40 is fixedly connected to the slide bar 39, and an adjustment seat 37 arranged away from the side of the knob 40 is rotatably connected to the end of the knob 40, the threaded hole is connected to the adjustment slide groove 38, and the two groups of adjustment slide grooves 38 are connected through the slide hole, and the slide hole is slidably matched with the slide bar 39;

[0060] The knob 40 can be used to operate the slide bar 39 to rotate, and the slide bar 39 can be connected or disconnected with the threaded hole. When the external thread of the slide bar 39 is connected with the threaded hole, the position of the slide bar 39 can be fixed. Figure 7 As shown, at this time, the leg frame 34 is unfolded;

[0061] When the external thread of the slide rod 39 is disconnected from the threaded hole, the leg frame 34 is pushed, and the support rod 36 can push the adjustment seat 37 to slide in the adjustment slide groove 38. At the same time, the adjustment seat 37 pushes the slide rod 39 to slide. The folded leg frame 34 is as shown in FIG. Figure 2 shown.

[0062] like Figure 6 or Figure 7 As shown, a pulley that can roll at the bottom of the installation cavity 42 is installed on the vertical rod of the leg frame 34 away from the support rod 36; after the leg frame 34 is folded, the pulley can roll at the bottom of the installation cavity 42, which is conducive to the transplanting vehicle 15 moving into the installation cavity 42.

[0063] Working principle of the present invention: When the sugar apple transplanting seedlings grow to a height of 50 cm and a stem thickness of about 10 cm, they are transplanted and trimmed. Then, according to the size of the transplanting seedlings, the roots of the transplanting seedlings are placed in the seedling root grooves 33 in the transplanting box 32. After the transplanting box 32 is loaded with the sugar apple transplanting seedlings, the transplanting vehicle 15 moves to one side of the vehicle frame 11. When the external thread of the slide rod 39 is disconnected from the threaded hole, the transplanting vehicle 15 moves to one side of the installation cavity 42 and pushes the leg frame 34. The support rod 36 can push the adjustment seat 37 to slide in the adjustment slide groove 38. At the same time, the adjustment seat 37 pushes the slide rod 39 to slide. After the leg frame 34 is folded, the pulley can roll at the bottom of the installation cavity 42, which is conducive to the transplanting vehicle 15 moving into the installation cavity 42.

[0064] When the motor 26 is working, the long rod is reversed within a certain range, and the two groups of positioning covers 16 can be pushed away from each other through the connecting rod 24. When the positioning covers 16 close to the control area move, one group of transmission rods 19 slides horizontally, thereby driving the gear 31 to rotate, and the other group of transmission rods 19 can slide relatively, so that the two groups of positioning covers 16 of the same group of transplanting mechanisms move relatively. When the two groups of positioning covers 16 of the same group of transplanting mechanisms approach each other, they will drive the two groups of limiting rods 22 to approach each other. The approach of the two groups of limiting rods 22 will limit the transplanting vehicle 15 in the installation cavity 42. The seedling stem holes on the two groups of positioning covers 16 can limit the shaking of the transplanted seedlings. At the same time, the positioning covers 16 can protect the top of the seedling roots, reduce the evaporation of water and the contact between the seedling roots and the outside, and improve the survival rate of the subsequent transplanted seedlings.

[0065] After transporting to the target location, the transplanting vehicle 15 is pushed out, a planting hole is dug, soil mixed with organic fertilizer is placed at the bottom of the planting hole, and then the excavated part of the inner soil is laid, the transplanted seedlings are placed in the planting hole, and the soil is filled and compacted. After watering, a layer of raw soil is covered.
