[0031] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0033] The mixed granular fertilizer is placed in the fertilizer box 2, and the arc rod 21 supports the fertilization component 8. The fertilization component 8 is connected with the horizontal support rod 22 and can be inserted into the paddy field soil 3-5 cm to transport the fertilizer to the optimal position. The setting of the driving component 3 can drive the transplanting component to insert the rice seedlings into the underwater soil. At the same time, quantitative fertilization is achieved through the coordinated setting of the transplanting component and the fertilization component 8, and the fertilizer is intermittently delivered to the soil 3-5 cm next to the rice, which is helpful for the rice to absorb the fertilizer.

[0034] During the fertilization process, the guide tube 81 will intermittently move into the soil. The water in the rice field is relatively sufficient and the soil is relatively soft. When the fertilizer enters the guide tube 81, it will enter the conical storage shell 88 under the action of gravity. The conical storage shell 88 is first inserted into the soil, and the conical storage shell 88 enters the soil 3-5cm under the push of the guide tube 81. During this process, the floating slide 85 will be placed on the surface of the soil. In the process of the conical storage shell 88 moving downward, the pull rope 86 is pulled by the floating slide 85 to make the conical storage shell 88 rotate and open. In the process of opening, the conical storage shell 88 can push the soil on both sides to both sides, and the fertilizer placed in the conical storage shell 88 falls into the expanded space, so that the fertilizer is sent to a depth of 3-5cm in the soil.

[0035] Specifically, a connecting piece 881 is fixedly connected to the top of the conical storage shell 88, a rotating column 89 is rotatably penetrated through the middle of the connecting piece 881, an end support piece 811 is fixedly connected to the bottom of the guide cylinder 81, and the end of the rotating column 89 is fixedly connected to the end support piece 811; a torsion spring 891 is fixedly connected to the outer wall of the rotating column 89, one end of the torsion spring 891 is fixedly connected to the side wall of the end support piece 811, and the other end of the torsion spring 891 is fixedly connected to the side wall of the connecting piece 881; the top of the conical storage shell 88 is connected to the middle of the bottom of the guide cylinder 81 via a corrugated connecting cover 882.

[0036] A compressing plate 82 is fixedly connected to the top of the guide cylinder 81 , a return spring 821 is fixedly connected to the end of the lower surface of the compressing plate 82 , and the lower end of the return spring 821 is fixedly connected to the upper surface of the horizontal support rod 22 .

[0037] When the conical storage shell 88 is pulled by the pull rope 86, the conical storage shell 88 will rotate. At this time, the connecting piece 881 and the rotating column 89 will rotate relative to each other. After the conical storage shell 88 transfers the fertilizer to the preset position, the floating slide 85 moves downward along the guide cylinder 81 due to gravity. Under the action of the torsion spring 891, the connecting piece 881 will rotate relative to the rotating column 89, and the conical storage shell 88 will be quickly closed through the connecting piece 881.

[0038] The end support piece 811 supports the rotating column 89 .

[0039] Specifically, a telescopic airbag 83 is fixedly connected to the middle of the lower surface of the compression plate 82 , and a connecting air pipe 84 is connected to one side of the telescopic airbag 83 . One end of the connecting air pipe 84 away from the telescopic airbag 83 extends into the guide tube 81 .

[0040] When the compression plate 82 moves downward, the bottom of the telescopic airbag 83 can contact the bottom of the horizontal support rod 22. At this time, the conical storage shell 88 is in the opening process, and the gas enters the guide cylinder 81 through the connecting air pipe 84. The fertilizer placed in the conical storage shell 88 is blown out by the gas. At the same time, it can also avoid blockage of the guide cylinder 81, so that the fertilizer can flow out of the guide cylinder 81 to the preset position each time.

[0041] Specifically, the fertilizer box 2 is provided with a discharge port near the guide cylinder 81, and a control component 25 is slidably provided at the discharge port. A fertilizer pipe 24 is connected to the lower end of the discharge port. The fertilizer pipe 24 is inclined, and the lower end of the fertilizer pipe 24 is connected to the guide cylinder 81.

[0042] Fertilizer intermittently enters the fertilizer pipe 24 through the fertilizer box 2, and then enters the guide cylinder 81 through the fertilizer pipe 24 for storage.

[0043] Specifically, the control component 25 includes an outer plate 261 and an inner plate 27, and the outer plate 261 and the inner plate 27 are connected by a transverse plate, and the transverse plate is slidably connected to the inner wall of the discharge port. The discharge port is sealed by the outer plate 261 and the inner plate 27, and a push plate 26 is fixedly connected to the top of the outer plate 261.

[0044] By moving the push plate 26, the outer plate 261 and the inner plate 27 can be driven to move upward. During this process, the fertilizer will leak out from the discharge port into the fertilizer pipe 24. Under the action of gravity, the outer plate 261 and the inner plate 27 will return to the initial position to block the discharge port. The outer plate 261 and the inner plate 27 are both metal plates.

[0045] Specifically, the driving assembly 3 includes a driving motor 31, which is fixedly connected to the upper surface of the mounting frame 1. The rice transplanting assembly includes a supporting seat 6, a rotating shaft 61 is rotatably connected to the middle of the supporting seat 6, a sprocket 62 is fixedly connected to the outer wall of the rotating shaft 61, and the output end of the driving motor 31 is connected to the sprocket 62 through a chain 32.

[0046] The driving motor 31 is turned on, and the driving motor 31 drives the sprocket 62 to rotate through the chain 32. During the rotation process, the sprocket 62 drives the rotating shaft 61 to rotate synchronously.

[0047] Specifically, a plurality of mounting wheels 63 are fixedly connected to the outer wall of the rotating shaft 61 , and both sides of the mounting wheels 63 are fixedly connected to transplanting rods 64 , the transplanting rods 64 can contact the pushing plate 26 , and the transplanting rods 64 and the guide cylinders 81 are staggeredly arranged.

[0048] The rotating shaft 61 can drive the mounting wheel 63 to rotate during the rotation process, and the mounting wheel 63 drives the transplanting rods 64 connected on both sides to rotate. The transplanting rods 64 can insert the rice seedlings dropped from the rice placing plate 4 into the soil during the rotation process. When the transplanting rods 64 rotate to the side close to the fertilizer box 2, the pushing plate 26 can be pushed to make the pushing plate 26 move upward for a distance. During this process, the fertilizer will leak out from the discharge port into the fertilizer pipe 24.

[0049] Specifically, a plurality of reciprocating cams 611 are fixedly connected to the outside of the rotating shaft 61 , and the reciprocating cams 611 can contact the re-compression sheet 82 .

[0050] The rotating shaft 61 can drive the reciprocating cam 611 to rotate during the rotation process. The reciprocating cam 611 can reciprocate and press the pressure-combining plate 82 downward during the rotation process. The return springs 821 connected at both ends of the pressure-combining plate 82 will be compressed during the downward movement. When the reciprocating cam 611 rotates to no longer contact the pressure-combining plate 82, the return spring 821 will push the pressure-combining plate 82 to its initial position.

[0051] Working principle: Turn on the driving motor 31, and the driving motor 31 drives the sprocket 62 to rotate through the chain 32. The sprocket 62 drives the rotating shaft 61 to rotate synchronously during the rotation process. The rotating shaft 61 can drive the reciprocating cam 611 to rotate during the rotation process. The rotating shaft 61 can drive the mounting wheel 63 to rotate during the rotation process. The mounting wheel 63 drives the transplanting rods 64 connected on both sides to rotate. The transplanting rods 64 can insert the rice seedlings dropped from the rice placing plate 4 into the soil during the rotation process. When the transplanting rods 64 rotate to the side close to the fertilizer box 2, the pushing plate 26 can be moved upward for a distance. During this process, the fertilizer will leak out from the discharge port into the fertilizer pipe 24. The intermittent entry of the fertilizer into the fertilizer pipe 24 is achieved by the reciprocating movement of the pushing plate 26 by the transplanting rods 64.

[0052] The reciprocating cam 611 can reciprocately press the compound pressure piece 82 during the rotation process. The return springs 821 connected at both ends of the compound pressure piece 82 will be compressed during the downward movement, and the guide cylinder 81 will intermittently move into the soil. The water in the rice field is relatively sufficient and the soil is relatively soft. When the fertilizer enters the guide cylinder 81, it will enter the conical storage shell 88 under the action of gravity. The conical storage shell 88 is first inserted into the soil. Under the push of the guide tube 81, the conical storage shell 88 enters the soil 3-5cm. During this process, the floating slide 85 will be placed on the surface of the soil. During the downward movement of the conical storage shell 88, the pull rope 86 is pulled by the floating slide 85 to make the conical storage shell 88 rotate and open. During the opening process, the conical storage shell 88 can push the soil on both sides to both sides, and the fertilizer placed in the conical storage shell 88 falls into the expanded space, so that the fertilizer is sent to a depth of 3-5cm in the soil. When the compression plate 82 moves downward, the bottom of the telescopic airbag 83 can contact the bottom of the horizontal support rod 22. When the conical storage shell 88 is pulled by the pull rope 86, the conical storage shell 88 will rotate. At this time, relative rotation occurs between the connecting piece 881 and the rotating column 89. After the conical storage shell 88 transfers the fertilizer to the preset position and moves upward, the floating slide 85 moves downward along the guide cylinder 81 due to gravity.

[0053] The conical storage shell 88 is in the process of being opened, and gas enters the guide cylinder 81 through the connecting air pipe 84, and the fertilizer placed in the conical storage shell 88 is blown out by the gas. At the same time, it can also avoid blockage of the guide cylinder 81, so that the fertilizer can flow out of the guide cylinder 81 to the preset position every time.
