[0035] There are three rotating cylinders 12, each of which is rotatably arranged at the bottom of the drive box 6 through a thrust ball bearing. The lower end of the drive cylinder 8 is fixedly connected to the rotating cylinder 12. A rotating rod 14 is connected to the drive cylinder 8 through a height adjustment mechanism 13. The upper end of the rotating rod 14 is movable through the rotating cylinder 12 and the drive cylinder 8 and then movably inserted into the vertical tube 7. A feeding groove 15 is opened in the rotating rod 14 and is connected to the vertical tube 7.

[0036] Spiral cutters 16, there are three spiral cutters 16, which are fixedly mounted on three rotating rods 14 respectively. The rotating rods 14 are provided with automatic fertilizing mechanisms 17;

[0037] The height adjustment mechanism 13 comprises:

[0038] An adjusting block 13 - 1 is fixedly sleeved on the rotating rod 14 and movably arranged in the rotating cylinder 12 . The rotating rod 14 is provided with an external thread 13 - 2 .

[0039] The adjusting cylinder 13-3 is rotatably sleeved on the rotating cylinder 12 through a bearing. An adjusting ring 13-4 is fixedly provided in the lower opening of the adjusting cylinder 13-3. The adjusting ring 13-4 is movably sleeved on the rotating rod 14. An internal thread 13-5 that cooperates with the external thread 13-2 is provided on the inner ring wall of the adjusting ring 13-4. When the adjusting ring 13-4 is rotated by the adjusting cylinder 13-3, the adjusting block 13-1 can be moved up and down in the rotating cylinder 12 through the cooperation of the external thread 13-2 and the internal thread 13-5, thereby adjusting the initial position height of the rotating rod 14 and realizing the depth adjustment when fertilizing the soil. The rotating rod 14 The upper fixed sleeve is provided with a splash plate 18, and the splash plate 18 is located below the external thread 13-2. The splash plate 18 can prevent soil from splashing upward and adhering to the external thread 13-2, thereby avoiding affecting the height adjustment of the rotating rod 14. A threaded locking rod 19 is penetrated through the side wall of the adjusting cylinder 13-3 by threaded rotation. A rubber pad is fixedly provided at one end of the threaded locking rod 19, and the rubber pad is arranged to conflict with the outer wall of the rotating cylinder 12. The rotation of the adjusting cylinder 13-3 on the rotating cylinder 12 can be restricted by the cooperation of the threaded locking rod 19 and the rubber pad, thereby preventing the adjusting cylinder 13-3 from rotating on the rotating cylinder 12 during fertilization.

[0040] The automatic fertilizing mechanism 17 comprises:

[0041] There are two guide rods 17-1, each of which is movably inserted into two slots provided at the lower end of the rotating rod 14. A spring 17-2 connected to the guide rod 17-1 is fixedly provided in the slot. The lower ends of the two guide rods 17-1 pass through the slots and are connected to the soil breaking head 17-3.

A blocking block 17-5 is fixedly provided on the upper end of the linkage rod 17-4, and the blocking block 17-5 is movably provided in the storage trough 22 opened in the feeding channel 15.

[0043] When using the utility model, the fertilizer in the fertilizer storage box 2 will enter the storage tank 22 in the feeding trough 15 through the feeding hose and the vertical pipe 7. When fertilizing is needed, the cart 1 can be pushed to the fertilizing position, and then the threaded locking rod 19 can be loosened to disengage the rubber pad from the rotating cylinder 12, and then the adjusting cylinder 13-3 can be rotated, and the adjusting cylinder 13-3 drives the adjusting ring 13-4 to rotate, and the outer thread 13-2 and the inner thread 13-5 are matched to make the rotating rod 14 drive the adjusting block 13-1 to move up and down in the rotating cylinder 12, thereby adjusting the initial position height of the rotating rod 14, and then tighten the threaded locking rod 19 to make the rubber pad contact to The rotating cylinder 12 generates a huge friction force to limit the rotation of the adjusting cylinder 13-3 on the rotating cylinder 12, and then the electric telescopic rod 5 is shortened and the motor 9 is started. The electric telescopic rod 5 drives the lifting plate 4 to move downward, and the lifting plate 4 drives the driving box 6 to move downward. The motor 9 drives the worm 11 to rotate, and the worm 11 drives the driving cylinder 8 to rotate through the worm gear 10, and the driving cylinder 8 drives the rotating cylinder 12 to rotate. The rotating cylinder 12 drives the rotating rod 14 to rotate through the adjusting block 13-1. When the earth-breaking head 17-3 conflicts with the ground and the rotating rod 14 continues to move downward, the earth-breaking head 17-3 will conflict with the lower end of the rotating rod 14, and the guide rod 17 -1 moves toward the inside of the slot and compresses the spring 17-2. The soil-breaking head 17-3 drives the blocking block 17-5 to move upward through the linkage rod 17-4 to block the upper opening of the storage trough 22. The fertilizer in the storage trough 22 will fall down into the feeding barrel trough at the lower position of the storage trough 22, and the blocking of the soil-breaking head 17-3 prevents the fertilizer from falling out of the rotating rod 14 during this process. In the process of driving the spiral cutter 16 to move downward and rotate, the spiral cutter 16 can dig a hole of a certain depth in the soil. Then the electric telescopic rod 5 extends to move the lifting plate 4 upward, and the lifting plate 4 drives the drive box 6 upward The soil-breaking head 17-3 moves out of the pit, and the lower end of the rotating rod 14, the soil-breaking head 17-3 and the spiral cutter 16 are moved out of the pit. At the same time, the spring 17-2 extends to push the guide rod 17-1 downward, and the guide rod 17-1 drives the soil-breaking head 17-3 to move out from the lower end of the rotating rod 14. At this time, the fertilizer in the feeding barrel trough below the storage trough 22 will fall directly into the pit, realizing layered fertilization of the soil at different depths, and the soil-breaking head 17-3 will drive the blocking block 17-5 to move downward through the linkage rod 17-4 to block the lower opening of the storage trough 22, so that the fertilizer in the feeding trough 15 above the storage trough 22 can fall down into the storage trough 22.

[0044] Compared with the prior art, the beneficial effects of the present invention are:

[0045] 1. Through the cooperation of the lifting plate 4, the electric telescopic rod 5, the drive box 6, the vertical pipe 7, the drive cylinder 8, the motor 9, the worm gear 10, the worm 11, the rotating cylinder 12 and the height adjustment mechanism 13, not only can the soil be fertilized in layers to improve the fertilization effect, but the soil fertilization depth can also be adjusted according to the fertilization needs;

[0046] 2. Through the cooperation of the automatic fertilizing mechanism 17, after digging a hole of appropriate size on the ground, the fertilizer can automatically fall into the hole, greatly improving the fertilizing efficiency;

[0047] 3. The threaded locking rod 19 and the rubber pad cooperate to generate a huge friction force between the rubber pad and the rotating cylinder 12, thereby preventing the adjusting cylinder 13-3 from rotating on the rotating cylinder 12 during the process of the rotating rod 14 and the spiral cutter 16 rotating to dig a hole in the ground;

[0048] 4. The splash plate 18 can prevent soil from splashing upward and adhering to the external thread 13 - 2 , thereby affecting the height adjustment of the rotating rod 14 .
