DETAILED DESCRIPTION

[0018] The following will be described in detail in combination with the accompanying drawings Figure 1 - Figure 4Further details of the application are provided below.

[0019] Embodiment one:

[0020] A seedling transplanting machine tail supporting device, including seedling transplanting machine body 1, seedling transplanting machine body 1 is prior art, can transplant seedlings, not too much in this application, the bottom outer wall of seedling transplanting machine body 1 is fixedly connected with fixed plate 10, the outer wall of both sides of fixed plate 10 is rotatably connected with first connecting frame 11, the outer wall of two first connecting frames 11 is fixedly installed with first hydraulic supporting leg 3, two first connecting frames 11 and fixed plate 10 rotatably exist certain limit, only a certain angle of rotation, and by driving two first connecting frames 11 to rotate, so that two first connecting frames 11 drive two first hydraulic supporting legs 3 to unfold, the supporting leg of two first hydraulic supporting legs 3 is in contact with the ground, it is convenient to support the tail of the machine, the outer wall of fixed plate 10 is provided with inner groove 6, the outer wall of inner groove 6 is rotatably connected with threaded rod 7, and the outer wall of threaded rod 7 is threadedly connected with moving seat 13, by driving threaded rod 7 to rotate, so that the output shaft of threaded rod 7 drives moving seat 13 to move, and then moving seat 13 moves to the outside, the outer wall of both sides of moving seat 13 is rotatably connected with two second connecting frames 12, the outer wall of two second connecting frames 12 is fixedly installed with second hydraulic supporting leg 4, by moving seat 13 moving to the outside, so as to make moving seat 13 drive two second hydraulic supporting legs 4 to move to the outside, and by moving two second hydraulic supporting legs 4 to the outside, then by driving two second connecting frames 12 to rotate, two second connecting frames 12 drive two second hydraulic supporting legs 4 to unfold, and then start two second hydraulic supporting legs 4, so that the supporting leg of two second hydraulic supporting legs 4 is in contact with the ground, the tail is supported, it is worth noting that first hydraulic supporting leg 3 and second hydraulic supporting leg 4 can be driven by opening hydraulic oil valve, so that the hydraulic oil enters first hydraulic supporting leg 3 and second hydraulic supporting leg 4, and then the supporting leg is in contact with the ground, the tail is stably supported.

[0021] The outer walls of the fixed plate 10 and the movable seat 13 are both fixedly connected to a drive box 9. The inner wall of the drive box 9 is rotatably connected to two worm gears 14, which are fixedly connected to the second connecting frame 12 and the first connecting frame 11, respectively. The inner wall of the drive box 9 is rotatably connected to a worm 15, which meshes with the two worm gears 14. By driving the worm 15 to rotate, the worm 15 drives the two worm gears 14 to rotate. The two worm gears 14 on the fixed plate 10 and the movable seat 13 drive the two first connecting frames 11 and the two second connecting frames 12 to rotate, thereby unfolding the two first hydraulic support legs 3 and the two second hydraulic support legs 4, improving the support effect on the tail. It is worth noting that the rotation of the two first connecting frames 11 and the two second connecting frames 12 is limited by a certain rotation angle on the movable seat 13 and the fixed plate 10, which facilitates the control of the rotation of the two first connecting frames 11 and the two second connecting frames 12.

[0022] Servo motors 16 are fixedly connected to the outer side walls of the drive box 9, and the output shafts of the servo motors 16 are fixedly connected to the worm gear 15. The two servo motors 16 located on the moving base 13 and the fixed plate 10 are synchronously started by an external power supply, so that their output shafts drive the worm gear 15 to rotate.

[0023] The outer side wall of the fixed plate 10 is fixedly connected to the drive motor 8, and the output shaft of the drive motor 8 is fixedly connected to the threaded rod 7. The drive motor 8 is started by an external power supply, so that the output shaft of the drive motor 8 drives the threaded rod 7 to rotate.

[0024] The implementation principle of the tail support device for a seedling transplanter in this embodiment is as follows: When the seedling transplanter is working, the drive motor 8 can be started by an external power switch, causing the output shaft of the drive motor 8 to drive the threaded rod 7 to rotate, thereby causing the threaded rod 7 to drive the moving seat 13 to move outward, thus causing the two second hydraulic support legs 4 located on the moving seat 13 to move to the outside. Then, the two servo motors 16 located on the moving seat 13 and the fixed plate 10 can be started by a power switch, causing the output shafts of the two servo motors 16 to synchronously drive the worm gear 15 to rotate, thereby causing the worm gear 15 to drive the worm wheels 14 on both sides to rotate synchronously, thus causing the two second hydraulic support legs 4 located on the moving seat 13 to move outward. The worm gears 14 on both sides of the fixed plate 10 and 13 drive the second connecting frame 12 and the first connecting frame 11 to rotate, which in turn drive the first hydraulic support leg 3 to rotate. This causes the first hydraulic support leg 3 and the second hydraulic support leg 4 on both sides to unfold. After unfolding, the hydraulic valves can be opened to allow hydraulic oil to enter the first hydraulic support leg 3 and the second hydraulic support leg 4 on both sides, so that the legs of the first hydraulic support leg 3 and the second hydraulic support leg 4 on both sides come into contact with the ground, thus providing support and stability to the tail of the seedling transplanter and improving its stability during operation.

[0025] The exemplary embodiment of the seedling transplanting machine tail supporting device provided by the present disclosure is described above with reference to the preferred embodiment, however, those skilled in the art can understand that various modifications and changes can be made to the above specific embodiment, and various technical features and structures proposed by the present disclosure can be combined without departing from the concept of the present disclosure, and without exceeding the protection scope of the present disclosure, the protection scope of the present disclosure is determined by the appended claims.
