DETAILED DESCRIPTION

[0025] The utility model will be further described below in combination with the drawings and embodiments.

[0026] Please combine with reference to Figures 1 to 8 A equidistance transplanting machine, including rack 1, on rack 1, ingeniously install a drive shaft 2 and a drive motor 3 for its power supply, the output shaft of drive motor 3 is firmly connected with the one end of drive shaft 2, ensure the stable transmission of power.

[0027] Two active turntables 4 are fixed on drive shaft 2 symmetrically, multiple duckbill assemblies 5 are installed between the two active turntables 4 in the way of equal angle. Every duckbill assembly 5 is composed of an inner lining frame 6 and left duckbill plate 8 and right duckbill plate 9 hinged on it through pivot 7, and such design makes the duckbill plate can open and close flexibly to adapt to different transplanting requirements.

[0028] In order to ensure that the duckbill assembly 5 always keeps vertical during the working process, a set of retaining devices 11 is specially designed on the frame 1. The retaining devices 11 include a driven turntable 12, which is in the same horizontal line with the rotation center of the driving turntable 4 and can smoothly rotate on the frame 1. A plurality of connecting rods 13 are fixed on the driven turntable 12 at equal angles, and one end of each connecting rod 13 is hingedly connected with a connecting plate 14. Meanwhile, two connecting shafts 15 are symmetrically fixed on the inner lining frame 6, and the left and right duckbill plates 8 and 9 are respectively provided with waist-shaped avoiding holes 16. A plurality of connecting seats 17 are fixed on the driving turntable 4 at equal angles, and one end of the connecting shaft 15 penetrates through the waist-shaped avoiding hole 16 and is rotationally connected with the connecting seat 17. In particular, the end of the connecting shaft 15 close to the left duckbill plate 8 is fixedly connected with one end of the connecting plate 14. It is worth mentioning that the distance between the rotation center of the driven turntable 12 and the rotation center of the driving turntable 4 is carefully set to be equal to the distance between the center line of the connecting shaft 15 and the center line of the connecting rod 13, which ensures that the inner lining frame 6 can always keep horizontal during the rotation of the driving turntable 4.

[0029] In order to drive the left and right duckbill plates 8 and 9 to rotate along the rotation shaft 7, the driving assembly 10 is installed on the driving turntable 4. The driving assembly 10 includes an arc-shaped driving plate 18, and the top end of each of the left and right duckbill plates 8 and 9 is integrally provided with an ear plate 19, and a driving wheel 20 is installed on the ear plate 19 through bolts. A plurality of arc-shaped driving plates 18 are fixed on the inner side of the driving turntable 4 at equal angles, and the arc-shaped driving plates 18 can tightly fit with the side wall of the driving wheel 20. In addition, the left and right duckbill plates 8 and 9 are respectively provided with screws 21, and the two screws 21 are connected together through a return spring 22. In this way, when the duckbill assembly 5 gradually moves to the lowest position and the left and right duckbill plates 8 and 9 are inserted into the soil, the driving wheel 20 will gradually contact and be pressed by the arc-shaped driving plate 18, so as to drive the left and right duckbill plates 8 and 9 to open and scrape the soil to form a gap. At this time, the return spring 22 is stretched, and the seedling falls into the soil under the action of gravity to complete the transplanting action.

[0030] In order to facilitate manual feeding of seedlings into the duckbill assembly 5, a feeding opening 28 is arranged on the top of the inner lining frame 6. Meanwhile, a seedling frame 23 for placing seedlings is installed on the top of the frame 1, which can conveniently place seedlings for the operator to take at any time.

[0031] In addition, in order to ensure that the driven rotating disc 12 can rotate stably, the frame 1 is further provided with a mounting plate 24, and four mounting shafts 25 are fixedly connected to the mounting plate 24. The end portions of the mounting shafts 25 are all rotationally connected with a limiting wheel 26, and a through hole 27 is arranged at the center of the driven rotating disc 12, and the edge of the through hole 27 is mounted on the inner side of the limiting wheel 26. In this way, the limiting wheel 26 can not only support the driven rotating disc 12, but also guide the rotation of the driven rotating disc 12, thereby ensuring the stable operation of the transplanter.

[0032] The above merely describes the embodiments of the present application, and does not limit the patent scope of the present application, and any equivalent structure or equivalent process transformation, or direct or indirect application in other related technical fields, which are made by using the content of the present application specification and drawings, are also included in the patent protection scope of the present application.
