[0026] By setting the disconnecting component, when the reseeding device needs to be pushed to another sowing ground, the transmission rod 7 can be disconnected from the self-locking component through the disconnecting component, so that when the device is subsequently moved to transfer the sowing ground, the roller 4 will no longer transmit kinetic energy to the sowing component when rolling, thereby making the sowing component in a stopped working state during the movement of the device, so as to avoid sowing grass seeds on non-sowing ground during the transfer of the device, avoid waste of grass seeds, and greatly improve the utilization rate of grass seeds.

[0027] The sowing assembly includes a rotating shaft 8 rotatably mounted inside the feeding tube 6 , a sowing roller 9 is fixedly sleeved on the outer surface of the rotating shaft 8 , and a plurality of seed storage grooves 10 are opened on the outer surface of the sowing roller 9 .

[0028] The self-locking assembly includes a fixed block 11 fixedly mounted on the feed tube 6, a rotating shaft 12 is rotatably connected to the fixed block 11, a worm 13 is fixedly sleeved on the outer surface of the rotating shaft 12, a worm gear 14 is meshed with the outer surface of the worm 13, and the worm gear 14 is fixedly sleeved with one end of the rotating shaft 8;

[0029] By setting the self-locking component, the self-locking function of the worm wheel 14 and the worm 13 is utilized to lock the sowing component, thereby improving the stability of the sowing component and preventing the sowing roller 9 from rotating due to the bumping and shaking of the device during the movement and transfer of the device, thereby further avoiding the waste of grass seeds and reducing the cost of reseeding grass seeds.

[0030] The disconnect assembly includes a fixed block 2 15 and a guide rod 16. The fixed block 2 15 is fixedly mounted on the frame 1, and the guide rod 16 is fixedly mounted on the triangular plate 2. The fixed block 2 15 is rotatably connected to a bidirectional threaded cylinder 17. Both ends of the bidirectional threaded cylinder 17 are threadedly connected to a threaded rod 18. The thread directions of the two threaded rods 18 are set in opposite directions. One end of the threaded rod 18 away from the bidirectional threaded cylinder 17 is fixedly connected to a connecting plate 19. The connecting plate 19 is movably sleeved on the guide rod 16, and a square threaded cylinder 17 is also rotatably installed on the connecting plate 19. Tube 20, a movable rod 1 21 and a movable rod 22 are movably inserted at both ends of the interior of the square tube 20, the movable rod 1 21 is fixedly connected to a circular plate 23 on the end away from the square tube 20, and a rectangular plug 24 is fixedly connected to the other side of the circular plate 23, and an extrusion spring 25 is fixedly connected between the circular plate 23 and the square tube 20, a rectangular slot 26 is opened on the transmission rod 7 at the position corresponding to the rectangular plug 24, and the rectangular plug 24 is embedded in the rectangular slot 26, and the end of the movable rod 2 22 away from the square tube 20 is fixedly connected to the rotating shaft 2 12.

[0031] The transmission assembly includes a driving pulley 27 and a driven pulley 28. The driving pulley 27 is fixedly sleeved on the outer surface of the central shaft 3, and the driven pulley 28 is fixedly sleeved on the outer surface of the transmission rod 7. A transmission belt 29 is connected between the outer surfaces of the driving pulley 27 and the driven pulley 28.

[0032] Working principle: When in use, the user first holds the push handle to push the reseeding device to the field to be sown, and walks in the middle of the furrows to be sown on both sides, and then places the grass seeds in the grass seed storage box 5. The grass seeds in the grass seed storage box 5 roll along the discharge pipe 6 to the seed storage groove 10 on the sowing roller 9, and the sowing roller 9 blocks the grass seeds, and then pushes the device forward. During the forward movement, the roller 4 rotates, driving the central shaft 3 to rotate synchronously, and through the cooperation of the active pulley 27, the driven pulley 28 and the transmission belt 29 in the transmission assembly, the driving pulley on the central shaft 3 is rotated. The kinetic energy of the transmission rod 7 can be transmitted to the transmission rod 7, so that the transmission rod 7 rotates synchronously, and through the coordinated use of the rectangular plug 24, the circular plate 23, the movable rod 1 21, the square tube 20 and the movable rod 2 22, the kinetic energy on the transmission rod 7 is transmitted to the rotating shaft 2 12 again, and drives the worm 13 to rotate, and at the same time drives the worm gear 14 meshing therewith to rotate, thereby driving the rotating shaft 1 8 and the sowing roller 9 to rotate synchronously. When the sowing roller 9 rotates, it can drive the grass seeds located in the seed storage groove 10 to move to the bottom of the sowing roller 9, and finally be discharged from the discharge pipe 6 and fall into the groove of the sowing ground, completing the grass seed reseeding operation;

[0033] After the reseeding of one of the sowing grounds is completed, when the reseeding device needs to be pushed to another sowing ground, the user first manually screws the two-way threaded cylinder 17 counterclockwise, and under the limiting effect of the guide rod 16 on the connecting plate 19 and the threaded rod 18, the two threaded rods 18 move to the side away from each other along the axial direction of the two-way threaded cylinder 17, thereby driving the connecting plate 19 and the square cylinder 20 to move synchronously, so that the movable rod 22 moves toward the inside of the square cylinder 20 (contracts), and the movable rod 1 21 moves toward the outside of the square cylinder 20 (extends). When the movable rod 1 21 is extended to the longest state, the square cylinder 20 continues to move in the direction of the lower material tube 6, and the circular plate 23 and the rectangular plug block 24 can be driven to move by the movable rod 1 21 until the rectangular plug block 24 is withdrawn. The rectangular slot 26 on the transmission rod 7 is pulled out, thereby disconnecting the transmission rod 7 from the rotating shaft 2 12, so that when the device is subsequently moved to transfer the sowing ground, the roller 4 no longer transmits kinetic energy to the sowing assembly when rolling, thereby making the sowing assembly in a stopped working state during the movement of the device, so as to avoid sowing grass seeds on non-sowing ground during the transfer of the device, thereby avoiding waste of grass seeds and greatly improving the utilization rate of grass seeds. In addition, through the setting of the self-locking component, the sowing assembly is locked by utilizing the self-locking function of the worm gear 14 and the worm 13, thereby improving the stability of the sowing assembly and preventing the sowing roller 9 from rotating due to the bumping and shaking of the device during the transfer of the device, thereby further avoiding waste of grass seeds and reducing the cost of reseeding grass seeds.

[0034] When the reseeding device is transferred to another sowing ground, the user screws the two-way threaded cylinder 17 clockwise to drive the two threaded rods 18 to move toward the inside of the two-way threaded cylinder 17, and then drives the square cylinder 20 to move toward the side close to the transmission rod 7 through the connecting plate 19, and supports the movable rod 1 21 through the extrusion spring 25, so that the movable rod 1 21 moves synchronously toward the side close to the transmission rod 7, and drives the rectangular plug 24 to be inserted into the rectangular slot 26 on the transmission rod 7, completing the connection between the transmission rod 7 and the self-locking component, so that when the subsequent device moves, the rotation of the roller 4 can drive the sowing The seed roller 9 rotates to carry out the sowing operation (the rectangular insert 24 is just opposite to the rectangular slot 26. If the rectangular insert 24 and the rectangular slot 26 are in an interlaced state, the rectangular insert 24 is pressed against the transmission rod 7 by the elastic force of the squeezing spring 25. In the subsequent movement of the device, the rotation of the roller 4 indirectly drives the transmission rod 7 to rotate, thereby driving the rectangular slot 26 to rotate. When the rectangular slot 26 rotates to the position opposite to the rectangular insert 24, the rectangular insert 24 can also be inserted into the rectangular slot 26 by the elastic force of the squeezing spring 25).

[0035] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
