[0022] This invention provides a furrow opener for a seeder. It has the following beneficial effects:

[0023] (1) The present invention is driven by two drive tracks at the lower end of the trenching machine head, which can drive the soil leveling shovel at the front end to first shovel up the upper dry and hard soil, and then start the flip trenching component to first adjust its height relative to the soil, and then break up the lower soil after shoveling it up again, and then dig the broken soil to both sides to form trenches, and then sow the seeds to form sowing.

[0024] (2) By starting the extension and retraction of the hydraulic cylinder, the ditching frame at the lower end of the ditching frame shaft can be moved down by rotating the component ditching shaft. When the loosening and digging bending rod touches the soil and loosens the soil, the ditching frame rotates at the other end with the ditching frame shaft as the axis due to the lever principle. The floating ditching arm and the follow-up ditching arm at the lower end then rotate. The digging drive motor is then started to drive the first turntable rotating in the follow-up ditching arm on the inner side to rotate. The second turntable is then driven to rotate through the first drive belt, and the third turntable is rotated through the coaxial connection. The fourth turntable on the inner side of the cutter head bracket on the other side is then driven to rotate through the second drive belt.

[0025] When the third turntable rotates, the cross shafts connected on both sides drive the soil-removing cutter head mounted at the end of the cutter head frame to rotate. When the fourth turntable rotates, the cross shafts mounted on both sides drive the digging cutter head mounted at the end of the cutter head frame to rotate, cutting the clumps of soil on both sides, thus facilitating soil removal from the rear.

[0026] (3) The present invention drives the sowing drive toothed disc inside the turntable housing to rotate via the sowing motor, and meshes with the sowing drive toothed ring in the middle to rotate. Subsequently, the gap between the sowing partitions can drive the seeds leaking out of the seed box outlet at the lower inner side of the seed storage box to rotate and fall into the soil when they are above the rotating blade sowing guide tube, thus completing the sowing.

[0044] A cutter head bracket 211 is fixedly installed in the middle of the trenching and turning frame 204. A fourth turntable shaft 226 is fixedly installed in the middle of the cutter head bracket 211, and a fourth turntable 227 is rotatably installed on the fourth turntable shaft 226. Cutter head bending frames 212 are fixedly installed on both sides of the cutter head bracket 211. A pitting rotating cutter head 213 is rotatably installed at the outer end of the cutter head bending frame 212. The pitting rotating cutter head 213 is connected to the fourth turntable shaft 226 through a cross shaft. A floating turning arm 228 is rotatably installed at the lower end of the trenching component support arm 202. A first follower turning support arm 229 is rotatably installed at the outer end of the floating turning arm 228. A turning support arm shaft 230 is rotatably installed at the lower end of the first follower turning support arm 229. The turning support arm shaft 230 is rotatably installed inside the trenching and turning frame 204.

The inner sides of the two soil-digging cutter heads 225 are fixedly connected to the second turntable 221 and the third turntable 222 through a cross shaft.

[0045] In the above technical solution, by activating the extension and retraction of the tilting hydraulic cylinder 209, the tilting shaft 201 of the component can be rotated, and the tilting frame 204 rotating at the lower end of the lower trenching frame shaft 203 can be moved down. When the loosening and digging bending rod 215 touches the soil and loosens the soil, the other end of the tilting frame 204 rotates around the tilting frame shaft 203 due to the lever principle, and then rotates with the floating tilting arm 228 and the first follower tilting support arm 229 at the lower end. Then, the digging drive motor 217 is activated to drive the first turntable 219 rotating in the second follower tilting support arm 216 on the inner side to rotate. Then, the second turntable 221 is driven to rotate through the first drive belt 220, and the third turntable 222 is rotated through the coaxial connection. Then, the fourth turntable 227 inside the cutter head bracket 211 on the other side is driven to rotate through the second drive belt 223.

[0046] When the third turntable 222 rotates, the soil-removing cutter head 225, which is rotatably mounted at the end of the cutter head bending frame 224, is driven to rotate through the cross shafts connected on both sides. When the fourth turntable 227 rotates, the cross shafts installed on both sides drive the hole-digging rotating cutter head 213, which rotates at the end of the cutter head bending frame 212, to rotate, cutting open the clumps of soil on both sides, thus facilitating soil removal from the rear.

[0047] like Figure 3 , Figures 9 to 12 As shown, the sowing turntable 207 includes: a turntable housing 2071, a sowing guide tube 2072, a sowing motor 2073, a sowing drive gear groove 2074, a seed dial 2075, a sowing partition 2076, a sowing drive gear ring 2077, and a sowing drive gear disc 2078; the sowing guide tube 2072 is integrally provided at the lower end of the turntable housing 2071, the sowing drive gear groove 2074 is provided at the upper end of the turntable housing 2071, and the sowing motor 2073 is fixedly installed on the outer surface of the turntable housing 2071. A seeding drive gear 2078 is fixedly installed at the end of the output shaft of the 3; a seed dial 2075 is rotatably installed in the middle of the outer shell 2071 of the turntable component; a plurality of seeding partitions 2076 are fixedly installed on the outer ring of the seed dial 2075; a seeding drive gear ring 2077 is fixedly installed in the middle section of the seeding partition 2076; the seeding drive gear ring 2077 is meshed with the seeding drive gear 2078; a seed storage box 2079 is integrally provided on the inner wall of the outer shell 2071 of the turntable component; a seed box outlet 20710 is opened on the inner surface of the seed storage box 2079.

[0048] In the above technical solution, the sowing drive toothed disc 2078 inside the turntable housing 2071 is driven to rotate by the sowing motor 2073, and meshes with the rotating sowing drive toothed ring 2077 in the middle. Subsequently, the gaps between the sowing partitions 2076 can drive the seeds leaking from the seed box outlet 20710 at the lower inner side of the seed storage box 2079 to rotate and fall into the soil when they are above the rotating blade sowing guide tube 2072, thus completing the sowing.

[0049] Working principle:

[0050] The present invention is driven by two drive tracks 9 at the lower end of the trenching machine head 1, which can drive the soil leveling shovel 10 at the front end to first shovel up the upper dry and hard soil. Then, the flipping trenching component 2 is activated. First, its height relative to the soil is adjusted. Then, the lower soil after shoveling up can be broken up again. The broken soil is then dug open to both sides to form trenches. Then, the seeds are sown to form sowing.

[0051] In this process, by activating the extension and retraction of the tilting hydraulic cylinder 209, the tilting shaft 201 of the component can be rotated, causing the tilting frame 204 at the lower end of the ditching frame shaft 203 to move downward. When the loosening and digging bending rod 215 touches the soil and loosens it, the other end of the tilting frame 204 rotates around the ditching frame shaft 203 due to the lever principle. It then rotates with the floating tilting arm 228 and the first follower tilting support arm 229 at the lower end. Subsequently, the digging drive motor 217 is activated to drive the first turntable 219 rotating in the second follower tilting support arm 216 on the inner side to rotate. Then, the second turntable 221 is driven to rotate through the first drive belt 220, and the third turntable 222, which is coaxially connected, rotates. Finally, the fourth turntable 227 on the inner side of the cutter head bracket 211 on the other side is driven to rotate through the second drive belt 223.

[0052] When the third turntable 222 rotates, the soil-removing cutter head 225, which is rotatably mounted at the end of the cutter head bending frame 224, is driven to rotate through the cross shafts connected on both sides. When the fourth turntable 227 rotates, the cross shafts installed on both sides drive the hole-digging rotating cutter head 213, which is rotatably mounted at the end of the cutter head bending frame 212, to rotate, cutting open the clumps of soil on both sides, thus facilitating soil removal from the rear.

[0053] The sowing drive toothed disc 2078 inside the turntable housing 2071 is driven to rotate by the sowing motor 2073, and meshes with the rotating sowing drive toothed ring 2077 in the middle. Subsequently, the gaps between the sowing partitions 2076 can rotate the seeds leaking from the seed box outlet 20710 at the lower inner side of the seed storage box 2079, and when they are above the rotating blade sowing guide tube 2072, they fall into the soil to complete the sowing.

[0054] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. All obvious variations or modifications derived from the technical solutions of the present invention are still within the protection scope of the present invention.
