[0028] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0029] In the description of this application, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application.

[0030] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. Throughout this application, unless otherwise specified, "plurality" means two or more.

[0031] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0032] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0033] like Figures 1 to 5As shown, a single-body main beam structure of a seed drill includes longitudinal beams. Specifically, the longitudinal beams include a lower longitudinal beam 1 and an upper longitudinal beam 2. The front end of the upper longitudinal beam 2 is connected to the front end of the lower longitudinal beam 1. The front ends of the upper longitudinal beam 2 and the lower longitudinal beam 1 are connected to a profiling device. The rear end of the lower longitudinal beam 1 is connected to a pressure wheel. A seed box 5 is mounted on the upper portion of the longitudinal beam, and the seed box 5 is connected to a seeding tube 6. A running wheel 3 is mounted on the lower portion of the longitudinal beam. A cam 12 is rotatably connected to the longitudinal beam and is transmission-connected to the running wheel 3. A cam frame 13 is also slidably connected to the longitudinal beam, and is capable of moving back and forth. The cam frame 13 is connected to a push-pull frame 15 that is sleeved on the seeding tube 6. During use, when the running wheel 3 rotates, it drives the cam 12 to rotate, and the cam frame 13 and the push-pull frame 15 move back and forth. The push-pull frame 15 strikes the seeding tube 6, preventing seeds from sticking to the seeding tube 6 and improving seeding efficiency. A fertilizer box 7 is also mounted on the upper portion of the longitudinal beam, and the fertilizer box 7 is connected to a fertilizer pipe 8. There are at least two push-pull frames 15, at least one of which is sleeved on the fertilizer pipe 8. During use, when the running wheel 3 rotates, the cam 12 rotates, and the cam frame 13 and the push-pull frame 15 move back and forth. The push-pull frame 15 strikes the fertilizer pipe 8, preventing the fertilizer from sticking to the fertilizer pipe 8 and improving the fertilization efficiency.

[0034] Specifically, the axle 4 of the running wheel 3 is connected to a driving sprocket 9, and the cam 12 is connected to a driven sprocket 11. A transmission chain 10 is interposed between the driving sprocket 9 and the driven sprocket 11. During operation, when the running wheel 3 rotates, the driving sprocket 9 drives the driven sprocket 11, which in turn drives the cam 12, causing the cam frame 13 and the push-pull frame 15 to move back and forth. This structure is convenient to use. Specifically, the push-pull frame 15 is shaped like a runway. During operation, the push-pull frame 15 moves back and forth, and the inner sides of the front and rear sides of the push-pull frame 15 alternately strike the sowing tube 6 or the fertilizer tube 8.

[0035] Specifically, a push-pull rod 14 is connected between the cam frame 13 and the push-pull frame 15, and a guide sleeve 17 that cooperates with the push-pull rod 14 is installed on the longitudinal beam. When in use, the push-pull rod 14 moves along the guide sleeve 17 and moves smoothly. A cross plate 18 is connected to the longitudinal beam, and the guide sleeve 17 is installed on the cross plate 18. When in use, the guide sleeve 17 is firmly installed, and the push-pull rod 14 moves along the guide sleeve 17 and moves smoothly. A buffer pad 19 is installed on the side of the cross plate 18 close to the push-pull frame 15. When in use, the risk of the push-pull frame 15 hitting the cross plate 18 is reduced. A spring 16 is connected between the upper part of the push-pull frame 15 and the longitudinal beam. When in use, the spring 16 is used to lift the push-pull frame 15, which is conducive to maintaining the shape of the push-pull rod 14 and the push-pull frame 15.

[0036] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and replacements can be made without departing from the technical principles of the present invention. These improvements and replacements should also be regarded as the scope of protection of the present invention.
