They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0024] like Figures 1 to 4As shown, this utility model discloses a push-pull dual-purpose seeder, including a frame 1, a hopper 2 fixed at the top of the frame 1, and rotatable wheels 3 installed at the bottom. A crossbar 101 is integrally formed on the frame 1, and a connecting rod 4 is fixedly connected to the crossbar 101 via a thread. A handle connecting plate 5 is welded to one end of the connecting rod 4. The handle connecting plate 5 has a through first handle connecting hole 51, and a through second handle connecting hole 61 is provided on one end of the handle 6. The second handle connecting hole 61 can be opposite to the first handle connecting hole 51. By inserting a bolt 300 into the first handle connecting hole 51 and the second handle connecting hole 61, and screwing a nut 400 into one side of the bolt 300 to provide corresponding damping, the handle... The handle 6 can rotate around the center line of the first handle connection hole 51 and the second handle connection hole 61; the handle connection plate 5 is also provided with a through first handle limiting hole 52, and there are multiple first handle limiting holes 52 arranged in a circle around the first handle connection hole 51. One side end of the handle 6 is provided with a through second handle limiting hole 62. When the handle 6 is rotated to the target angle (such as the push position or the drag position), the second handle limiting hole 62 is aligned with the corresponding first handle limiting hole 52. The angle can be locked by inserting the locking pin 200 to ensure the stability of the handle 6.

[0025] In addition, the handle 6 is provided with a support plate 8 at the end away from the connecting rod 4. The support plate 8 is provided with a support 8. The support plate 8 is provided with a detachable tractor head connecting plate 9 at the end away from the handle 6. The tractor head connecting plate 9 is used to connect to the trailer. In actual use, the angle of the handle 6 can be adjusted by turning the handle 6 in different directions to switch between push mode and push-pull mode. For example, when the handle 6 is turned to an angle that is easy for the worker to push (such as 45°) in the direction towards the hopper 2, it can be locked by inserting the locking pin 200. At this time, the worker can perform push-planting operation. When the handle 6 is turned in the direction away from the hopper 2 so that the support plate 8 can be close to the trailer, it can be fixed to the trailer by the tractor head connecting plate 9 by threaded connection. At this time, the worker can use the trailer to pull the frame 1 to perform drag-and-pull planting operation, thus realizing push-and-pull dual use and improving the flexibility of use.

[0026] In this embodiment, a first through-hole is provided on the connecting plate of the support tube 8, and a second through-hole 81 is provided on one side end of the support tube 8. The second through-hole 81 can be opposite to the first through-hole 8. By inserting the bolt 300 into the first through-hole 8 and the second through-hole 81, and screwing the nut 400 into one side of the bolt 300 to provide corresponding damping, the support tube 8 can rotate around the center line of the first through-hole 8 and the second through-hole 81. Thus, when performing hand-push seeding operations, by flipping the support tube 8, the side connecting the tractor head connecting plate 9 can be moved down to avoid the tractor head connecting plate 9 protruding and affecting the worker's gripping of the handle 6. When performing drag seeding operations, the support tube 8 can be flipped in the opposite direction so that the tractor head connecting plate 9 can be close to the trailer, thereby facilitating connection with the trailer.

[0027] In addition, to prevent the holder 8 from malfunctioning after being flipped, a first holder 8 limiting hole is provided through the connecting plate of the holder 8. There are two first holder 8 limiting holes located on both sides of the first holder 8 connecting hole. A second holder 82 is provided through one end of the holder 8. In this way, after the holder 8 is flipped, the second holder 82 on the holder 8 can be aligned with the first holder 8 limiting hole. A locking pin 200 is inserted between the first holder 8 limiting hole and the second holder 8 limiting hole 82 to limit the holder 8 and ensure the stability of the holder 8.

[0028] In this embodiment, the detachable connection structure between the support 8 and the tractor connecting plate 9 is as follows: a symmetrical pressure plate 10 is welded to one end of the support 8 facing the tractor connecting plate 9. The pressure plate 10 has a through pin hole and a pin shaft 11 is provided in the pin hole. The tractor connecting plate 9 has a through fitting hole 91. The tractor connecting plate 9 is fitted onto the outer periphery of the pin shaft 11 through the fitting hole 91. By limiting the tractor connecting plate 9 with the pressure plates 10 on both sides, the tractor connecting plate 9 can be prevented from falling off.

[0029] In this embodiment, a support tube connecting plate 12 is fixed to the outer periphery of the connecting rod 4. The support tube connecting plate 12 is provided with a rotatable support tube 13. The support tube 13 is located on the side away from the support tube connecting plate 12 as a support end, which can contact the ground to support the frame 1. The support tube connecting plate 12 is provided with a through first support tube connecting hole 121, and one end of the support tube 13 is provided with a through second support tube connecting hole 131. The second support tube connecting hole 131 can be opposite to the first support tube connecting hole 121. By inserting a bolt 300 into the first support tube connecting hole 121 and the second support tube 131, the support tube 13 can be supported. The support tube 13 is connected to the pipe 131, and a nut 400 is screwed into one side of the bolt 300 to provide corresponding damping. This allows the support tube 13 to rotate around the center line of the first support tube connection hole 121 and the second support tube connection hole 131. In this way, when performing manual sowing operations, the support tube 13 can be rotated downwards so that its support end can contact the ground and support the frame 1, so that the workers can rest. When performing drag sowing operations, the support tube 13 can be reversed so that its support end is away from the ground to prevent the support end from contacting the ground and causing interference during dragging.

[0030] In this embodiment, a first support tube limiting hole 122 is provided through the support tube connecting plate 12, and a second support tube limiting hole 132 is provided through one end of the support tube 13. The second support tube limiting hole 132 can be opposite to the first support tube limiting hole 122. The first support tube limiting hole 122 and the second support tube limiting hole 132 are connected by inserting a locking pin 200 to limit the support tube 13, thereby ensuring the stability of the support tube 13 when providing support.

[0031] In addition, a retaining sleeve 14 is fixed to the outer periphery of the handle 6. The retaining sleeve 14 is provided with a through third support tube limiting hole 141, and the support end is provided with a fourth support tube limiting hole 133 that can be opposite to the third support tube limiting hole 141. In this way, when dragging and sowing operations are carried out, after rotating the support tube 13 to the target angle by reversing it, the third support tube limiting hole 141 can be opposite to the fourth support tube limiting hole 133. At this time, a locking pin 200 is inserted between the third support tube limiting hole 141 and the fourth support tube limiting hole 133 to limit the support tube 13 and prevent the support tube 13 from sagging, thereby ensuring that the support end can be stably away from the ground.

[0032] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
