[0025] Embodiment 1:
[0026] Please refer to Figure 2 , Figure 3 and Figure 5A corn planter with adjustable spacing includes a bracket 1, which is characterized in that: the left and right sides of the outside of the bracket 1 are rotatably connected to moving wheels 2, the front side of the bracket 1 is rotatably connected to a rotating shaft 4, both ends of the rotating shaft 4 are provided with transmission components, a plurality of limit blocks 5 are fixedly connected to the outer periphery of the rotating shaft 4, three rotating rings 15 are slidably connected to the outer side of the limit blocks 5, and the front and rear sides of the three rotating rings 15 are fixedly connected to a soil covering plow 16, a fixed rod 6 is fixedly connected to the front side of the bracket 1 and located above the rotating shaft 4, three mounting blocks 7 are slidably connected to the outer side of the fixed rod 6, and the rear sides of the three mounting blocks 7 are fixedly connected to a frame 8, a pull rod 9 is slidably connected to the inside of the frame 8, and a stopper is fixedly connected to the bottom of the pull rod 9. Plate 10, a limit rod 11 is fixedly connected to the inner wall of the rear side of the frame 8, a plug rod 12 is slidably connected to one side of the outer side of the limit rod 11, a spring 13 is sleeved on the other side of the outer side of the limit rod 11, a connecting rod 14 is arranged between the baffle 10 and the plug rod 12, the outer side of the baffle 10 is slidably connected to the inside of the frame 8, the plug rod 12 passes through the frame 8 and the mounting block 7 and is plugged into the fixed rod 6, one end of the spring 13 is fixedly connected to the inner wall of the frame 8, the other end of the spring 13 is fixedly connected to the outside of the plug rod 12, one end of the connecting rod 14 is rotatably connected to the bottom of the baffle 10, the other end of the connecting rod 14 is rotatably connected to the outside of the plug rod 12, and a handle 25 is fixedly connected to the top of the pull rod 9.
[0027] Specifically, when the position of the mounting block 7 needs to be adjusted, it is only necessary to pull the pull rod 9 to drive the baffle 10 to move, and then drive the connecting rod 14 to rotate and push the plug rod 12 to slide on the outside of the limit rod 11, and squeeze the spring 13 until the plug rod 12 is completely out of the fixed rod 6, so that the mounting block 7 can be moved on the outer periphery of the fixed rod 6, and the movement of the pull rod 9 can be transmitted to the plug rod 12 through the connecting rod 14, so as to realize the fixation and release of the mounting block 7, and the position of the plug rod 12 is prevented from being offset by the action of the limit rod 11, and the spring 13 is used to provide elastic potential energy for the reset of the plug rod 12, thereby driving the pull rod 9 and the baffle 10 to reset, and the handle 25 provides a holding point for the operator. Under the action of the limit block 5, the rotating ring 15 is driven to rotate synchronously while the rotating shaft 4 rotates, and at the same time does not affect the adjustment of the position of the covering plow 16.
[0028] Embodiment 2:
[0029] See also Figure 1 - Figure 4, this embodiment provides a technical solution based on Embodiment 1: Two connecting rods 17 are fixedly connected to the bottom of the mounting block 7. One end of the two connecting rods 17 away from the mounting block 7 is rotatably connected to the outside of the rotating ring 15. A feeding pipe 18 is fixedly connected to the rear side of the mounting block 7. A feeding assembly is arranged on the top of the support 1. The feeding assembly includes a material distribution bin 3. The bottom of the material distribution bin 3 is fixedly connected to the top of the support 1. A impeller 21 is rotatably connected inside the material distribution bin 3. Pulley 22 are fixedly connected to the outer sides of the impeller 21 and the moving wheel 2 respectively. A synchronous belt 23 is sleeved between the two pulleys 22. A plurality of discharge ports 24 are fixedly connected to the bottom of the material distribution bin 3. The transmission assembly includes a second gear 20. The second gear 20 is fixedly connected to the side end of the rotating shaft 4. A first gear 19 is fixedly connected to the inner side of the moving wheel 2. The first gear 19 and the second gear 20 are meshed and connected. The feeding pipe 18 is arranged below the discharge port 24.
[0030] Specifically, the mounting block 7 is connected by the connecting rod 17, and the other end is rotatably connected to the rotating ring 15. The purpose is not to affect the rotation of the rotating ring 15 driven by the rotating shaft 4. The corn seeds are pushed towards the discharge port 24 by the rotation of the impeller 21. The power of the movement of the moving wheel 2 is transmitted to the impeller 21 to drive its movement through the pulley 22 and the synchronous belt 23. The power of the movement of the moving wheel 2 is transmitted through the meshing of the first gear 19 and the second gear 20, driving the rotating shaft 4 to rotate in the reverse direction.
[0031] At the same time, the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.
[0032] During operation, first move the device to the land where sowing is required. When it is necessary to adjust the planting spacing, pull the pull rod 9 to drive the baffle 10 to move, then drive the connecting rod 14 to rotate and push the plug rod 12 to slide outside the limiting rod 11, and compress the spring 13 until the plug rod 12 completely disengages from the inside of the fixed rod 6, then the mounting block 7 can move on the outer periphery of the fixed rod 6, and thus the position of the feeding pipe 18 can be adjusted. And when adjusting the position of the mounting block 7, the position of the soil covering plow 16 can be adjusted together, greatly improving the efficiency and continuity of the sowing operation.
[0033] Subsequently, the corn seeds are poured into the inside of the material distribution bin 3. Connect the support 1 to other external traction devices. The rotation of the moving wheel 2 can be driven by the movement of the traction device. At this time, the moving wheel 2 drives the first gear 19 to rotate. Since the first gear 19 and the second gear 20 are meshed and connected, when the first gear 19 rotates, it drives the second gear 20 to rotate in the reverse direction. The rotation of the rotating shaft 4 is driven through the transmission of the second gear 20. At this time, under the positioning of the limiting block 5, the rotating ring 15 can rotate synchronously with the rotating shaft 4. At this time, the soil covering plow 16 can rotate, and the rotation direction is opposite to that of the moving wheel 2, so that when the device is moving forward, the land can be dug to facilitate subsequent sowing operations.
[0034] When the moving wheel 2 rotates, under the transmission of the pulley 22 and the synchronous belt 23, the impeller 21 can be rotated, so that the impeller 21 can push the corn seeds to roll into the discharge port 24. Open the valve outside the discharge port 24, and the corn seeds will fall to the top of the feeding pipe 18 and then fall into the digging pit through the conduction of the feeding pipe 18, thus completing the planting.
