[0027] Working principle and advantages of the present invention: When the circular reclamation fertilizer application machine is in use, the working process is as follows: like Figure 1 , Figure 2 , Figure 3 and Figure 7As shown, the tool is installed on the mechanical equipment through the connecting frame 15, and the tool is driven by the mechanical equipment to move to the fruit tree to be ditched, and the fruit tree enters through the gap of the C-shaped frame 1 and is located at the center of the C-shaped frame 1. At this time, the driving motor 3 and the ditching motor 16 are started to work, and the ditching motor 16 drives the cutter disc 20 to rotate through the sprocket assembly. At the same time, the driving motor 3 drives the rotating shaft 22 to rotate through the reduction box 4, so that the rotating shaft 22 drives the gear 2 23 and the gear 3 24 to rotate synchronously through the sprocket assembly, so that the gear 2 23 and the gear 3 24 drive the C-shaped rack 14 to rotate, and then the C-shaped rack 14 drives the square steel 5 and the ditching frames 25 at both ends to rotate, so that the ditching frame 25 drives the cutter disc 20 to draw a circle around the fruit tree. The circular trenching operation is carried out, and at the same time as the trenching, the fertilizer in the fertilizer bin 17 is sprinkled into the circular trench through the fertilizer guide groove 18, so as to realize the circular trenching fertilization of the fruit trees, so that the trenching and fertilization can be carried out around the drip line where the absorbing roots of the fruit trees are concentrated. Compared with the strip trenching fertilization, the contact range between the absorbing roots of the fruit trees and the fertilizer is effectively increased, which can significantly improve the fertilizer utilization rate and reduce the waste of fertilizer in the area between fruit trees and the pollution of the environment. The circular trenching fertilization method can thoroughly prune the root system of the fruit tree, enhance the vitality of the root system, better absorb water and nutrients in the soil, and promote the growth of the aboveground part, especially the crown part. The trenching depth can be achieved by adjusting the height of the C-type frame 1 by mechanical equipment. After the trenching is completed, the C-type frame 1 can be removed from the fruit tree by mechanical equipment.

[0028] like Figure 1 and Figure 3 As shown, when it is necessary to adjust the deflection angle of the ditching frame 25, the angle adjustment motor is controlled to work, and the locking cylinder 12 works at the same time, and the block 13 is moved away from the gear 7, and the lock of the gear 7 is released, so that the angle adjustment motor drives the gear 7 to rotate, and then the gear 7 drives the two spur racks 9 to move in opposite directions, so that the two spur racks 9 drive the two telescopic rods 11 to move away from or close to each other, and then the telescopic rods 11 drive the angle between the ditching frame 25 and the square steel 5 to be adjusted through the pin rod 2 40 and the bar through hole 2 42. After the angle adjustment is completed, the angle adjustment motor stops working, and the locking cylinder 12 drives the block 13 to be stuck on the gear 7, so that the gear 7 cannot rotate, thereby ensuring that the angle between the ditching frame 25 and the square steel 5 remains stable after the angle adjustment, and the angle range between the ditching frame 25 and the square steel 5 is 90°~105°. After the deflection, the working surface of the cutter head 20 is a conical surface, which is more suitable for the distribution characteristics of the root system of fruit trees.

[0029] like Figure 1 , Figure 2 , Figure 3 and Figure 6As shown, when the trenching diameter needs to be adjusted, first loosen the fastening bolts on the telescopic rod 11 so that the telescopic rod 11 can be extended and retracted, and then rotate the screw rod 29 so that the screw rod 29 drives the two inner cylinders 6 to move away from or closer to each other through thread transmission, thereby causing the two inner cylinders 6 to drive the two trenching frames 25 to move away from or closer to each other. After the adjustment is completed, tighten the fastening bolts on the telescopic rod 11 to fix the telescopic rod 11, thereby achieving a change in the spacing between the trenching, fertilizing and covering mechanisms at both ends, thereby adjusting the distance between the cutter head 20 and the center point of the C-shaped rack 14, so that the operating radius is adjusted accordingly as needed.

[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 8 As shown, when the fruit tree is at the center position of the C-shaped frame 1, the two clamping plates 21 are at both sides of the fruit tree, and the electric control valve 38 is in a closed state when the drive motor 3 is started, and the turntable 27 is driven to rotate while the gear 3 24 rotates, so that the turntable 27 drives the piston plate 44 to reciprocate in the pump barrel 28 through the pin rod 3 43, the slide 46 and the connecting rod 2 45, so that the piston plate 44 alternately applies suction force and compression force to the pump barrel 28. Since the conduction direction of the one-way valve 1 47 points to the inside of the pump barrel 28, and the conduction direction of the one-way valve 2 48 points to the air pipe 39, the pump barrel 28 sucks external air into the pump barrel 28 through the one-way valve 1 47, and transports it to the slide barrel 26 through the one-way valve 2 48 and the air pipe 39, so that the slide plate 30 compresses the spring 31 and moves upward, and the slide plate 30 drives the lifting rod 32 to move upward while moving upward , so that the lifting rod 32 drives the clamping plate 21 to clamp the fruit tree through the two connecting rods 36, so that when ditching, the stability of the C-type frame 1 is maintained, ensuring the smooth progress of ditching, avoiding the reaction force caused by ditching that makes the C-type frame 1 shake frequently and with a large amplitude, thereby protecting the fruit tree and improving the ditching effect and efficiency. Moreover, after the two clamping plates 21 clamp the fruit tree, the fruit tree is at the center of the C-type frame 1, so that the distance from each part of the ditching to the fruit tree is more uniform. During the ditching process, when the air pressure in the slide cylinder 26 is greater than the set value of the pressure relief valve 37, the air is discharged to keep the pressure stable. When the ditching is completed and the drive motor 3 stops working, the electric control valve 38 is opened synchronously at this time, and the slide plate 30 drives the lifting rod 32 to move downward under the action of the restoring force of the spring 31, so that the lifting rod 32 drives the clamping plate 21 away from the fruit tree through the connecting rod 36.
