[0020] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0021] like Figure 1-4 As shown, an embodiment of the utility model provides a planting depth adjustment mechanism for a vegetable transplanter, comprising a vertical tube 1, a mounting shell 5 being fixed to the top end of the vertical tube 1, a worm 6 being connected to the interior of the mounting shell 5 through a bearing, one end of the worm 6 extending to the outside of the mounting shell 5 and being fixed with a handwheel 8, a telescopic tube 2 being inserted into the interior of the vertical tube 1, a nut 10 being fixed to the inner wall of the telescopic tube 2, a screw 9 being connected to the bottom outer wall of the mounting shell 5 through a bearing, the screw 9 being threadedly connected to the inside of the nut 10, the top end of the screw 9 extending to the interior of the mounting shell 5 and being fixed with a worm gear 7, the worm 6 being meshed with the worm gear 7, and a seedling planting mechanism 4 being provided on one side of the telescopic tube 2.

[0022] Specifically, in this embodiment, a vertical tube 1 is included, a mounting shell 5 is fixed to the top of the vertical tube 1, a worm 6 is connected to the inside of the mounting shell 5 through a bearing, one end of the worm 6 extends to the outside of the mounting shell 5 and is fixed with a handwheel 8, which is convenient for rotating the worm 6, a telescopic tube 2 is inserted into the interior of the vertical tube 1, the telescopic tube 2 can be extended from the inside of the vertical tube 1, a nut 10 is fixed to the inner wall of the telescopic tube 2, a screw 9 is connected to the outer wall of the bottom of the mounting shell 5 through a bearing, the screw 9 is threadedly connected to the inside of the nut 10, and when the screw 9 rotates, the telescopic tube 2 is driven to extend from the inside of the vertical tube 1, and the top of the screw 9 extends to the inside of the mounting shell 5 and is fixed. There is a worm gear 7, and the worm 6 is engaged with the worm gear 7. When the worm 6 rotates, it drives the worm gear 7 and the screw 9 to rotate. A seedling planting mechanism 4 is provided on one side of the telescopic tube 2. The seedling planting mechanism 4 is an inherent part of the vegetable transplanter in the prior art. The seedlings come out from the inside of the seedling planting mechanism 4. The height of the seedling planting mechanism 4 determines the planting depth of the vegetable transplanter. A limiting groove 11 is provided on the outer wall of one side of the telescopic tube 2, and a limiting block 12 is inserted into the outer wall of one side of the bottom end of the vertical tube 1. One side of the limiting block 12 is located in the limiting groove 11. When the height of the seedling planting mechanism 4 is adjusted, the limiting groove 11 and the limiting block 12 limit the movement of the telescopic tube 2 to prevent the telescopic tube 2 from being separated from the vertical tube 1.

[0023] The utility model provides a planting depth adjustment mechanism for a vegetable transplanter, which drives the worm wheel 7 and the screw 9 to rotate through the worm 6, so that after the height of the seedling planting mechanism 4 is adjusted, the worm 6 and the worm wheel 7 can keep the height of the seedling planting mechanism 4 unchanged through the self-locking principle, thereby making it more convenient for the vegetable transplanter to adjust the planting depth.

[0024] In another embodiment provided by the present invention, an arc groove 20 is provided on the outer wall of one side of the handwheel 8 near the mounting shell 5, and a guide sleeve 16 is fixed to the outer wall of one side of the mounting shell 5.

One end of the guide column 19 is provided with a hemispherical end 15 adapted to the arc groove 20, and the hemispherical end 15 of the guide column 19 can extend to the inside of the arc groove 20, and a spring 18 is provided inside the guide sleeve 16. The spring 18 applies elastic force to the slider 17, so that the hemispherical end 15 of the guide column 19 cooperates with the arc groove on the handwheel 8, thereby making the handwheel 8 stable in a natural state, making the seedling planting mechanism 4 more stable after height adjustment; a mounting frame 3 is fixed to the outer wall of one side of the bottom end of the telescopic tube 2, and the seedling planting mechanism 4 is fixed to the inside of the mounting frame 3. The seedling planting mechanism 4 is fixed on the mounting frame 3 in a manner that is easy to disassemble using existing technology, so that the seedling planting mechanism 4 can be easily disassembled.

[0025] In another embodiment provided by the present invention, a filling pipe 13 is welded to the outer wall of one side of the mounting shell 5, and one end of the filling pipe 13 is connected to a sealing cover 14 through a thread. Lubricating oil can be added to the interior of the mounting shell 5 through the provided filling pipe 13, thereby reducing the wear of the worm 6 and the worm wheel 7 during meshing transmission, thereby extending the service life of the adjustment mechanism, and the filling pipe 13 is sealed by the sealing cover 14 to prevent foreign matter from entering the mounting shell 5 through the filling pipe 13; a mounting plate 21 is fixed to the outer wall of one side of the vertical pipe 1, and a mounting hole 22 is opened on the outer wall of one side of the mounting plate 21, and the mounting plate 21 can be fixed to the vegetable transplanter with bolts through the mounting hole 22.

[0026] Working principle: When the height of the seedling planting mechanism 4 needs to be adjusted, the handwheel 8 drives the worm 6 to rotate, so that the worm 6 drives the worm wheel 7 and the screw 9 to rotate, and the rotation of the screw 9 drives the telescopic tube 2 to extend from the inside of the vertical tube 1, thereby adjusting the height of the seedling planting mechanism 4. When the height of the seedling planting mechanism 4 is adjusted, the limit groove 11 and the limit block 12 limit the movement stroke of the telescopic tube 2 to prevent the telescopic tube 2 from detaching from the vertical tube 1.

[0027] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
