[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] In the present invention, a C-shaped rack is driven to rotate by a driving motor, so that the C-shaped rack drives the trenching, fertilizing and covering mechanism through the operating radius adjustment mechanism to perform circular trenching and fertilizing around the fruit trees, so that trenching and fertilizing can be performed around the drip line where the absorbing roots of the fruit trees are concentrated. Compared with strip trenching and fertilizing, 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 to the environment. The circular trenching and fertilizing method can thoroughly prune the roots of the fruit trees, enhance the vitality of the root system, better absorb water and nutrients in the soil, and promote the growth of the above-ground parts, especially the crown parts.

[0018] In the present invention, while annular trenching is being performed at the root system of the fruit tree, the clamping stabilization mechanism is driven to clamp the fruit tree. On the one hand, the fruit tree is kept at the center of the C-shaped frame, so that the distance from each trenching point to the fruit tree is more uniform. On the other hand, the stability of the C-shaped frame is maintained to ensure smooth trenching and avoid the reaction force caused by trenching that causes the C-shaped frame to shake frequently and with a large amplitude, thereby protecting the fruit tree and improving the trenching effect and efficiency.

[0037] The working principle and advantages of the present invention: When the circular reclamation fertilizing machine is in use, the working process is as follows:

[0038] like Figure 1 、 Figure 2 、 Figure 3 and Figure 7As shown, the machine is mounted on the mechanical equipment through the connecting frame 15, and the machine is driven by the mechanical equipment to move to the fruit tree to be furrowed, and the fruit tree enters through the gap of the C-shaped frame 1 and is in the center position of the C-shaped frame 1. At this time, the driving motor 3 and the furrowing motor 16 are started to work, and the furrowing 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 furrowing frames 25 at both ends to rotate, so that the furrowing frame 25 drives the cutter disc 20 to draw a circle around the fruit tree. The track 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 circular trenching and fertilizing of the fruit trees, so that trenching and fertilizing can be carried out around the drip line where the absorbing roots of the fruit trees are concentrated. Compared with strip trenching and 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 and environmental pollution in the area between fruit trees. The circular trenching and fertilization method can thoroughly prune the roots of the fruit trees, enhance the vitality of the root system, better absorb water and nutrients in the soil, and promote the growth of the above-ground parts, especially the crown parts. 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.

[0039] like Figure 1 and Figure 3 As shown, when the deflection angle of the trenching frame 25 needs to be adjusted, the angle adjustment motor is controlled to work, and the locking cylinder 12 is operated at the same time, and the block 13 is moved away from the gear 7, 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 straight racks 9 to move in opposite directions, so that the two straight 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 trenching frame 25 and the square steel 5 to adjust the angle through the pin rod 240 and the bar through hole 242. 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 trenching frame 25 and the square steel 5 remains stable after the angle adjustment. The angle range between the trenching frame 25 and the square steel 5 is 90°~105°. After 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.

[0040] 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 29 so that the screw 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 can be adjusted accordingly as needed.

[0041] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 8 As shown, when the fruit tree is in the center position of the C-shaped frame 1, the two clamping plates 21 are on 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 three 24 rotates, so that the turntable 27 drives the piston plate 44 to move back and forth in the pump barrel 28 through the pin rod three 43, the slide 46 and the connecting rod two 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 one 47 points to the inside of the pump barrel 28, and the conduction direction of the one-way valve two 48 points to the air pipe 39, the pump barrel 28 draws external air into the pump barrel 28 through the one-way valve one 47, and transports it to the slide barrel 26 through the one-way valve two 48 and the air pipe 39, thereby causing the slide plate 30 to compress the spring 31 and move upward. When the slide plate 30 moves upward, it drives the lifting rod 32 to move upward. , so that the lifting rod 32 drives the splint 21 to clamp the fruit tree through the two connecting rods 36, thereby maintaining the stability of the C-type frame 1 during ditching, ensuring the smooth progress of ditching, and avoiding the reaction force caused by ditching that causes the C-type frame 1 to shake frequently and with a large amplitude, thereby protecting the fruit tree and improving the ditching effect and efficiency. Moreover, after the two splints 21 clamp the fruit tree, the fruit tree is at the center of the circle of the C-type frame 1, thereby making the distance from each ditching point to the fruit tree 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 under the action of the restoring force of the spring 31, the slide plate 30 drives the lifting rod 32 to move downward, so that the lifting rod 32 drives the splint 21 away from the fruit tree through the connecting rod 36.
