[0015] In summary, the present invention includes the following beneficial technical effects: The present invention provides a seed tube, a fertilizer tube and a movable main frame. During sowing and fertilizing, when the supporting movable frame stops moving, the power telescopic rod pushes the ring frame to move downward through the movable main frame, and the ring frame drives the fertilizer tube and the seed tube to be inserted into the crushed soil. The seeds in the seed box fall into the soil through the seed tube, and then the fertilizer in the fertilizer box falls around the seeds through the annular space between the fertilizer tube and the seed tube. After the seed tube and the fertilizer tube are pulled out of the soil, the soil covers the seeds and the fertilizer, providing an environment for the seeds to grow. At the same time, the covered soil reduces the volatilization of the fertilizer, and the fertilizer surrounding the seeds in an annular shape can be fully absorbed by the seeds.

[0016] The present invention provides an air storage ring, an air pressure push plate, a pressure telescopic rod, a through groove and a damping elastic plate. When the movable main frame drives the ring frame to move upward, the pressure telescopic rod generates resistance to the upward movement of the air storage ring under the obstruction of the lateral end of the seed conveying tube, so that the air storage ring moves downward relative to the air pressure push plate, driving multiple damping elastic plates on the surface of the vertical pole to continuously misalign with the through groove, pushing the gas in the air storage ring into the interlayer, and as the air pressure inside the interlayer increases, the two elastic cylinders inside and outside the seed tube expand, respectively sealing the inside of the seed tube and the lower end of the space between the seed tube and the fertilizer tube, so that the fertilizer and seeds added to the inside of the seed tube and the fertilizer tube will not fall off before being inserted into the soil.

[0017] The present invention arranges a spiral feeding plate A, a spiral feeding plate B, a hard plate, an elastic paddle plate and a one-way baffle. When the ring frame moves upward and drives the elastic paddle plate to move upward through the fixed vertical rod to contact the hard plate on the surface of the conveyor belt, the elastic paddle plate pushes the conveyor belt through the hard plate to drive the spiral feeding plate A and the spiral feeding plate B to rotate. When the spiral feeding plate A and the spiral feeding plate B rotate, they respectively push seeds and fertilizers into the seed tube and fertilizer tube blocked by the expanded elastic cylinder.

[0018] The present invention arranges a prism shaft, a vertical shaft, a circular groove and a prism groove. When the movable main frame moves upward to drive the fertilizer tube and the seed tube to move upward and separate from the soil, the movable main frame drives the prism shaft to move into the prism groove through the bifurcated frame, so that when the driving motor rotates, the vertical shaft and the active bevel gear are driven to rotate through the prism telescopic shaft and the prism shaft. The driven bevel gear drives the moving wheel to rotate by meshing with the active bevel gear to change the position of the fertilizer tube and the seed tube. Before the movable main frame moves downward to insert the fertilizer tube and the seed tube into the soil, the prism shaft moves downward to separate from the prism groove and enter the circular groove, so that the vertical shaft stops rotating and the supporting movable frame stops moving, so that the seed tube and the fertilizer tube are stably and vertically inserted into the soil.

A plurality of ring frames 9 are fixedly installed on the front of the movable main frame 10, and a seed tube 11 is fixedly penetrated at the axis of the ring frame 9.

[0023] The upper end of the seed tube 11 is slidably plugged with a seed transfer structure 6, the upper end of the seed transfer structure 6 is fixedly plugged into the lower end of the seed box 4, the upper end of the seed transfer structure 6 is connected to the lower end of the seed box 4, the seed transfer structure 6 includes a seed delivery pipe 61 and a seed connecting box 62, the lower end of the seed delivery pipe 61 is slidably plugged into the upper end of the seed tube 11, the upper end of the seed connecting box 62 is fixed to the lower end of the seed box 4, the lower end of the seed connecting box 62 is fixedly connected to the upper surface of the seed delivery pipe 61, and the outer surface of the seed tube 11 is fixedly sleeved with a fertilizer. Pipe 12, the upper end of the fertilizer pipe 12 is bent forward and then bent upward, the upper end of the fertilizer pipe 12 is located in front of the ring frame 9, the upper end of the fertilizer pipe 12 is slidably plugged with a fertilizer transfer structure 7, the upper end of the fertilizer transfer structure 7 is installed at the lower end of the fertilizer box 3, the fertilizer transfer structure 7 includes a fertilizer conveying pipe 71 and a fertilizer connecting box 72, the lower end of the fertilizer conveying pipe 71 is slidably plugged into the upper end of the fertilizer pipe 12, the lower end of the fertilizer connecting box 72 is fixedly connected to the upper surface of the fertilizer conveying pipe 71, and the upper end of the fertilizer connecting box 72 is fixed to the lower end of the fertilizer box 3.

[0024] The inner wall of the seed tube 11 is provided with an interlayer 111, and the inner and outer ring surfaces of the lower end of the seed tube 11 are fixedly plugged with elastic tubes 112. The inner diameter of the fertilizer tube 12 is larger than the outer diameter of the seed tube 11. The fertilizer entering the fertilizer tube 12 falls between the fertilizer tube 12 and the seed tube 11. When the air pressure in the interlayer 111 increases, the elastic tubes 112 arranged on the inner and outer rings of the seed tube 11 expand to respectively block the inside of the seed tube 11 and the space between the seed tube 11 and the fertilizer tube 12. A storage is arranged above the ring frame 9. The air ring 113 has an air pressure push plate 119 inserted therein for sliding movement. The upper surface of the air pressure push plate 119 is fixed with a vent pipe 114. The lower end of the vent pipe 114 slides through the inner bottom wall of the air ring 113. The end of the vent pipe 114 located below the air ring 113 is fixedly inserted through the outer surface of the seed tube 11. The vent pipe 114 is connected to the interior of the interlayer 111. The upper surface of the air ring 113 is fixed with a pressure telescopic rod 115. The upper end of the pressure telescopic rod 115 is located at the seed conveying Below the transverse end of the tube 61, a damping structure 116 is installed on the upper surface of the ring frame 9, and the air storage ring 113 is damped and sleeved on the upper end of the damping structure 116. A blocking rod 117 is fixed on the back of the air storage ring 113, and a hanging frame 118 is fixed on the back of the main frame 2. The blocking rod 117 is located on the inner ring surface of the hanging frame 118. When the ring frame 9 moves upward to drive the pressure telescopic rod 115 to contact the seed delivery tube 61 and continue to move upward, the air pressure push plate 119 moves upward in the air storage ring 113 to push the air storage ring 113. The gas is pushed into the interlayer 111 from the vent pipe 114, which increases the air pressure in the interlayer 111 and causes the two elastic tubes 112 to deform elastically. After the ring frame 9 moves downward to insert the seed tube 11 and the fertilizer tube 12 into the soil, the baffle rod 117 is driven by the air storage ring 113 to contact the hanging frame 118, thereby generating resistance to the downward movement of the air storage ring 113, causing the air pressure push plate 119 to move downward relative to the air storage ring 113, and re-drawing the gas in the interlayer 111 into the air storage ring 113 to shrink the elastic tube 112.

[0025] The damping structure 116 includes a vertical rod 1161, and a plurality of damping elastic plates 1163 are fixedly passed through the front side of the vertical rod 1161. A through groove 1162 is provided on the bottom side of the air storage ring 113 and above the vertical rod 1161. The vertical rod 1161 is slidably inserted into the inside of the through groove 1162. The front-to-back length of the through groove 1162 is greater than the front-to-back thickness of the vertical rod 1161, and the front-to-back length of the through groove 1162 is less than the length of the damping elastic plate 1163. When the air storage ring 113 is blocked by the pressure telescopic rod 115 and the hanging frame 118 from moving relative to the ring frame 9, the damping elastic plate 1163 passes through the through groove 1162 through elastic deformation. When the air storage ring 113 is not blocked by the pressure telescopic rod 115 and the hanging frame 118, the relative position between the air pressure push plate 119 and the air storage ring 113 is limited, so that the air pressure in the interlayer 111 is stabilized.

[0026] The upper ends of the fertilizer conveying pipe 71 and the seed conveying pipe 61 are both bent to the left, and a spiral feeding plate A611 is rotatably inserted inside the left bent end of the seed conveying pipe 61, and a spiral feeding plate B711 is rotatably inserted inside the left bent end of the fertilizer conveying pipe 71. A steering wheel 612 is rotatably installed on the front of the seed connecting box 62 and above the spiral feeding plate A611. The steering wheel 612, the front end of the spiral feeding plate A611 and the front end of the spiral feeding plate B711 are distributed in a right triangle. The steering wheel 612, the front end of the spiral feeding plate A611 and the front end of the spiral feeding plate B711 are transmitted through a conveyor belt 614. A plurality of hard plates 613 are fixed to the outer ring surface of the conveyor belt 614. The back of the conveyor belt 614 is a vertical surface. The rear lower side of the conveyor belt 614 is provided with A fixed vertical rod 615, the lower end of which is fixed to the upper surface of the adjacent ring frame 9, the fixed vertical rod 615 is located behind the hard plate 613, an elastic paddle 616 is fixed to the front of the upper end of the fixed vertical rod 615, a one-way baffle 617 is arranged above the conveyor belt 614, the upper end of the one-way baffle 617 is unidirectionally elastically connected to the seed connecting box 62, after the ring frame 9 moves upward to make the air pressure push plate 119 contact the inner top wall of the air storage ring 113, when the ring frame 9 continues to move upward, the pressure telescopic rod 115 is compressed, the fixed vertical rod 615 drives the elastic paddle 616 to contact the hard plate 613, and the conveyor belt 614 is driven to rotate, driving the spiral feeding plate A611 and the spiral feeding plate B711 to rotate, and the fertilizer and seeds are respectively pushed into the blocked seed tube 11 and the fertilizer tube 12.

[0027] A power telescopic rod 13 is fixed to the upper surface of the movable main frame 10, and the upper end of the power telescopic rod 13 is fixed to the main frame 2. A fork frame 14 is fixed to the back of the movable main frame 10, and a power drive structure 8 is installed at the other end of the fork frame 14. The lower end of the power drive structure 8 is connected to the adjacent moving component 5.

[0028] The power drive structure 8 includes a driving motor 81, a long shaft 82, a prism telescopic shaft 83 and a prism shaft 84. The fork frame 14 is fixedly sleeved on the outer surface of the driving motor 81. The upper end of the long shaft 82 is fixed to the output end of the driving motor 81, the lower end of the long shaft 82 is fixed to the upper end of the prism telescopic shaft 83, and the lower end of the prism telescopic shaft 83 is fixed to the upper end of the prism shaft 84. A vertical shaft 85 is arranged below the driving motor 81. A prism groove 86 is provided on the upper surface of the vertical shaft 85. A circular groove 87 is provided on the inner bottom wall of the prism groove 86. The inner diameter of the circular groove 87 is greater than the maximum length of the prism groove 86. The prism shaft 84 is slidably inserted into the interior of the prism groove 86. The prism groove 86 is adapted to the prism shaft 84. The vertical shaft 85 is rotatably connected to the supporting movable frame 1. An active bevel gear 89 is fixedly sleeved on the lower end of the vertical shaft 85. A driven bevel gear 8 is meshed below the active bevel gear 89. 8. The driven bevel gear 88 is fixedly sleeved on the outer surface of the adjacent support shaft 52. When the movable main frame 10 moves upward to drive the fertilizer pipe 12 and the seed pipe 11 to move upward and separate from the soil, the movable main frame 10 drives the prism shaft 84 to move into the prism groove 86 through the fork frame 14, so that when the driving motor 81 rotates, the vertical shaft 85 and the active bevel gear 89 are driven to rotate through the prism telescopic shaft 83 and the prism shaft 84. The driven bevel gear 88 drives the moving wheel 51 to rotate by meshing with the active bevel gear 89 to change the position of the fertilizer pipe 12 and the seed pipe 11. Before the movable main frame 10 moves downward to insert the fertilizer pipe 12 and the seed pipe 11 into the soil, the prism shaft 84 moves downward to separate from the prism groove 86 and enter the circular groove 87, so that the vertical shaft 85 stops rotating, and the supporting movable frame 1 stops moving, so that the seed pipe 11 and the fertilizer pipe 12 are stably and vertically inserted into the soil.

[0029] The working principle is as follows: fertilizers and seeds are added into the seed box 4 and the fertilizer box 3 respectively, the power telescopic rod 13 controls the movable main frame 10 to move up and down, and the ring frame 9 moves up and down synchronously with the movable main frame 10. When the movable main frame 10 drives the ring frame 9 to move upward, the pressure telescopic rod 115 generates resistance to the upward movement of the air storage ring 113 under the obstruction of the lateral end of the seed conveying pipe 61, so that the air storage ring 113 moves downward relative to the air pressure push plate 119, driving the multiple damping elastic plates 1163 on the surface of the vertical rod 1161 to continuously displace with the through groove, so as to push the air storage ring 113 downward. The gas in the ring 113 is pushed into the interlayer 111. As the air pressure in the interlayer 111 increases, the two elastic tubes 112 inside and outside the seed tube 11 expand, respectively blocking the inside of the seed tube 11 and the lower end of the space between the seed tube 11 and the fertilizer tube 12. Then, when the ring frame 9 continues to move upward, the elastic plate 616 is driven by the fixed vertical rod 615 to move upward and contact the hard plate 613 on the surface of the conveyor belt 614. The elastic plate 616 pushes the conveyor belt 614 through the hard plate 613 to drive the spiral feeding plate A611. The spiral feeding plate A611 and the spiral feeding plate B711 rotate, and the spiral feeding plate A611 and the spiral feeding plate B711 respectively push the seeds and fertilizers into the seed tube 11 and the fertilizer tube 12 blocked by the expanded elastic tube 112 when rotating. Then, when the movable main frame 10 drives the ring frame 9 to move downward, the damping elastic plate 1163 contacts the air storage ring 113 to stabilize the air pressure in the interlayer 111 and expand the elastic tube 112. When the movable main frame 10 drives the fertilizer tube 12 and the seed tube 11 to be inserted into the soil, the expanded elastic tube 112 prevents the soil from entering the fertilizer tube 12. The material tube 12 and the seed tube 11 are blocked, and then when the movable main frame 10 continues to move downward, the blocking rod 117 contacts the inner bottom wall of the hanging frame 118, thereby generating resistance to the downward movement of the air storage ring 113, causing the air pressure push plate 119 to move downward relative to the air storage ring 113, and the gas in the interlayer 111 is re-drawn into the air storage ring 113, causing the elastic tube 112 to contract. When the seed tube 11 and the fertilizer tube 12 move upward, the seeds and fertilizers in the seed tube 11 and the fertilizer tube 12 fall into the soil, and the fertilizers are distributed in a ring shape around the seeds.

[0030] The above are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
