At this time, the sliding plate 24 will seal the cavity 21 at the bottom of the conical plate 2 due to its own gravity. First, different types of fertilizers are placed in a plurality of silos 6 to adapt to different crops. The fertilization of multiple crops can be completed through one fertilizer barrel 1. The position of the limit rod 8 is adjusted through the transmission assembly 9 according to the position of the fertilization required. The position of the limit rod 8 determines The rotation angle of the conical plate 2 also affects the fertilization position, so the position of the limit rod 8 is adjusted by the transmission component 9. When the position of the limit rod 8 is adjusted, when fertilizing, the discharge port 28 of the discharge ring plate 27 is rotated to the vicinity of the required fertilizer through the discharge component 3. When automatic fertilization is performed, the bottom plate 12 is placed on the soil surface, and then the telescopic member 14 is started. The fertilizer barrel 1 is driven to descend together with the conical plate 2 through the telescopic member 14, that is, to cut into the soil. The vertically arranged conical plate 2 can smoothly cut into the soil. During the cutting process, During the process, the discharging assembly 3 is driven to drive the discharging ring plate 27 to rotate, so that the discharging port 28 is connected with the silo 6, and the amount of fertilizer is controlled by the time of connection. The discharging assembly 3 is started again to reverse the discharging ring plate 27, so that the silo 6 is closed, and the discharging is completed. The fertilizer will enter the cavity 21 inside the conical plate 2 along the silo 6.

At this time, the sliding plate 24 will seal the cavity 21 at the bottom of the conical plate 2 due to its own gravity. First, different types of fertilizers are placed in a plurality of silos 6 to adapt to different crops. The fertilization of multiple crops can be completed through a fertilizer barrel 1. The position of the limit rod 8 is adjusted through the transmission assembly 9 according to the position of fertilization required, that is, the rotating plate 7 is rotated. When the rotating plate 7 is rotated, the second gear ring 93 meshes with the second gear 91. The threaded rod 92 rotates, and the threaded rod 92 rotates, thereby driving the three limit rods 8 to move to the same radial position, so that the rotation angle of the conical plate 2 can be limited. The position of the limit rod 8 determines the rotation angle of the conical plate 2, and also affects the fertilization position. The position of the limit rod 8 is adjusted by the transmission component 9. When the position of the limit rod 8 is adjusted, when fertilizing, the discharge port 28 of the discharge ring plate 27 is rotated to the vicinity of the required fertilizer through the discharge component 3. When automatic fertilization is performed, the bottom plate 12 is placed on the soil surface, and then the telescopic member 14 is started to drive the fertilizer barrel through the telescopic member 14. 1 is lowered together with the conical plate 2, that is, it cuts into the soil. The vertically arranged conical plate 2 can smoothly cut into the soil. During the cutting process, the discharging assembly 3 is driven to drive the discharging ring plate 27 to rotate, so that the discharging port 28 is connected with the silo 6. The amount of fertilizer is controlled by the time of connection. The discharging assembly 3 is started again to reverse the discharging ring plate 27, so that the silo 6 is closed, and the discharging is completed. The fertilizer will enter the cavity 21 inside the conical plate 2 along the silo 6. When the conical plate 2 reaches the specified position, the winding assembly 5 is started to rotate the conical plate 2. Under the blocking action of the positioning rod 8, when the conical plate 2 rotates to contact with the limiting rod 8, the winding of the winding assembly 5 will directly act on the sliding plate 24, so that the sliding plate 24 is separated from the bottom of the conical plate 2. At this time, the fertilizer falls to the specified position inside the soil, thereby completing the supply of fertilizer, and then the connecting rope 200 is unwound, so that the sliding plate 24 closes the bottom of the conical plate 2, and then the telescopic part 14 is started to separate the soil between the conical plate 2 and the pressing plate 25 from the soil below. At this time, the connecting rope 200 is continued to be unwound, and the soil falls and covers the fertilizer, so that the fertilizer can be fully covered.

[0046] See also Figure 4 , Figure 5 , Figure 6 In one embodiment, it also includes a driving component 4, and the driving component 4 is used to drive the rotating plate 7 to rotate.

The amount of fertilizer is controlled by the time of connection. The discharging component 3 is started again to reverse the discharging ring plate 27, so that the silo 6 is closed, and the discharging is completed. The fertilizer will enter the silo 6 along the silo. The cavity 21 inside the conical plate 2, when the conical plate 2 reaches the specified position at the bottom, the winding assembly 5 is started, and the conical plate 2 is rotated by the winding assembly 5. Under the blocking action of the limit rod 8, when the conical plate 2 rotates to contact the limit rod 8, the winding of the winding assembly 5 will directly act on the sliding plate 24, so that the sliding plate 24 is separated from the bottom of the conical plate 2. At this time, the fertilizer falls to the specified position inside the soil, thereby completing the fertilizer supply, and then the telescopic member 14 is started, and the soil between the conical plate 2 and the pressing plate 25 is separated from the soil below. At this time, when the conical plate 2 is unfolded again, the pressing plate 25 pushes the soil down and covers the fertilizer under the restoring force of the spring 26, so that the fertilizer can be fully covered.

[0059] See also Figure 6 , Fig. 9 , Fig.10 In one embodiment, a main rope 20 is connected between the connecting rope 200 and the winding assembly 5.

[0060] In this embodiment, a main rope 20 is wound around the connecting shaft, and one end of the main rope 20 away from the connecting shaft is connected to a plurality of connecting ropes 200 , and the connecting ropes 200 are connected to the sliding plate 24 .

[0061] By additionally providing a main rope 20 between the connecting rope 200 and the winding assembly 5, it is possible to prevent the multiple connecting ropes 200 from getting entangled or "tightened" during the winding process, thereby increasing the winding resistance.

[0062] See also Figure 1 , Figure 2 , Figure 3 In one embodiment, a threaded sleeve 19 is fixedly mounted on the top plate 11 , and a plurality of external threads 10 are arranged on the outer peripheral surface of the fertilizer cylinder 1 .

[0063] In this embodiment, three external threads 10 are arranged on the outer circumferential surface of the fertilizer cylinder 1 , and different depths are determined by the number of the external threads 10 .

[0064] When carrying out automatic fertilization, the bottom plate 12 is placed on the soil surface, and the telescopic length is determined according to the soil depth where the fertilizer needs to be buried. Then the telescopic member 14 is started, and the fertilizer barrel 1 is driven to descend together with the conical plate 2 by the telescopic member 14, that is, to cut into the soil. The vertically arranged conical plate 2 can smoothly cut into the soil. The arranged pressing plate 25 can play the role of isolating the rotating plate 7 from the soil. In the process of vertical cutting, due to the provision of the external thread 10 and the threaded sleeve 19, the fertilizer barrel 1 will rotate at the same time during the descent process. The rotation of the fertilizer barrel 1 will drive the conical plate 2 to rotate at the same time. The conical plate 2 descends and rotates at the same time, so that the soil block below can be cut circumferentially, thereby reducing the resistance of the conical block when closing. At the same time, the pressing plate 25 is still located on the soil surface during the cutting process. In the process of cutting, the discharging assembly 3 is driven to drive the discharging ring plate 27 to rotate, so that the discharging port 28 is connected with the silo 6, and the amount of fertilizer is controlled by the time of connection. Start again. The discharging assembly 3 causes the discharging ring plate 27 to reverse, thereby closing the silo 6 and completing the discharging. The fertilizer will enter the cavity 21 inside the conical plate 2 along the silo 6. When the conical plate 2 reaches the specified position at the bottom, the winding assembly 5 is started to rotate the conical plate 2. Under the blocking action of the limit rod 8, when the conical plate 2 rotates to contact the limit rod 8, the winding of the winding assembly 5 will directly act on the sliding plate 24, thereby separating the sliding plate 24 from the bottom of the conical plate 2. At this time, the fertilizer falls. To the designated position inside the soil, thereby completing the supply of fertilizer, and then start the telescopic member 14, the soil between the conical plate 2 and the pressing plate 25 is separated from the soil below, and at the same time, during the driving upward process, the fertilizer cylinder 1 will rotate again at the same time, so that the soil attached to the outer peripheral surface of the conical block can be cleared under the action of centrifugal force, and when the conical plate 2 is reopened, the pressing plate 25 pushes the soil down and covers the fertilizer under the action of the restoring force of the spring 26, so that the fertilizer can be fully covered.

[0065] The working principle of the present invention is as follows: when performing automatic fertilization, the bottom plate 12 is placed on the soil surface, and then the telescopic member 14 is started, and the fertilizer barrel 1 is driven to descend together with the conical plate 2 through the telescopic member 14, that is, to cut into the soil. The vertically arranged conical plate 2 can smoothly cut into the soil. In the process of vertical cutting, due to the provision of the external thread 10 and the threaded sleeve 19, the conical plate 2 can perform circumferential cutting on the soil block below during the descent process. The discharging assembly 3 is driven to drive the discharging ring plate 27 to rotate, so that the discharging port 28 is connected with the silo 6, and the time of connection is controlled. The amount of fertilizer is controlled, and the discharging component 3 is started again to reverse the discharging ring plate 27, thereby closing the silo 6 and completing the discharging. The fertilizer will enter the cavity 21 inside the conical plate 2 along the silo 6. When the conical plate 2 reaches the specified position at the bottom, the winding component 5 is started to rotate the conical plate 2 through the winding component 5. Under the blocking action of the limit rod 8, when the conical plate 2 rotates to contact the limit rod 8, the winding of the winding component 5 will directly act on the sliding plate 24, thereby separating the sliding plate 24 from the bottom of the conical plate 2. At this time, the fertilizer falls to the specified position inside the soil, thereby completing the supply of fertilizer.
