[0011] In the aforementioned adjustable frame structure for a seeder, the two ends of the curved beam frame are detachably connected to the left support frame and the right support frame, respectively.

[0012] In the aforementioned adjustable frame structure for a seeder, the curved beam frame includes a curved beam, a front support rod, and a connecting rod. One end of the curved beam is inserted into a connecting pipe. The front support rod is connected to the curved beam, and both ends of the connecting rod are provided with connecting plates. The front support rod is provided with a fixing plate that is connected to the connecting plates.

[0013] In the aforementioned adjustable frame structure for a seeder, the second fixing plate is an L-shaped structure.

[0014] The outstanding and beneficial technical effects of this utility model compared to the prior art are:

[0015] This invention allows for adjustment of the frame structure width by changing the lengths of the front and rear connecting rods, thus meeting the frame width requirements of different seeders, reducing storage pressure, and the left and right support frames are used to connect the seeder and support some components.

Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0020] like Figures 1-2As shown: An adjustable frame structure for a seeder includes a left support frame 1 and a right support frame 2. A front connecting rod 3 and a rear connecting rod 4 are detachably connected between the left support frame 1 and the right support frame 2. Connecting plates 31 are respectively provided at both ends of the front connecting rod 3. Fixing plates 32 that cooperate with connecting plates 31 are provided on the left support frame 1 and the right support frame 2. The connecting plates 31 and the fixing plates 32 are detachably connected by a connector. Locking sleeves 41 are provided at the bottom of both ends of the rear connecting rod 4. The locking sleeves 41 are mounted on the left support frame 1 and the right support frame 2 and are detachably connected by a connector. Specifically, the width of the frame structure can be adjusted by changing the length of the front and rear connecting rods, which can meet the frame width requirements of different seeders and reduce storage pressure.

[0021] In the aforementioned adjustable frame structure for a seeder, both the left support frame 1 and the right support frame 2 include a crossbeam 11, a lower connecting rod 12, an upper connecting rod 13, an upper support rod 14, and a connecting pipe 15. The lower connecting rod 12 is fixedly connected to the crossbeam 11 and is located below the crossbeam 11. The upper connecting rod 13, the upper support rod 14, and the connecting pipe 15 are interconnected with the crossbeam 11 to form a support frame. Specifically, the crossbeam 11, the lower connecting rod 12, the upper connecting rod 13, the upper support rod 14, and the connecting pipe 15 are all connected to each other by welding and are all perpendicular to each other.

[0022] In the aforementioned adjustable frame structure for a seeder, the lower connecting rod 12 is perpendicular to the crossbeam 11. Specifically, this ensures the stability of the connection between the two, and the lower connecting rod and the crossbeam are connected to each other by welding.

[0023] In the aforementioned adjustable frame structure for a seeder, a triangular support 17 is provided between the upper support rod 14 and the connecting pipe 15, which specifically improves the connection stability between the two.

[0024] In the aforementioned adjustable frame structure for a seeder, the connecting plate 31 and the fixing plate 32 are each provided with three connecting holes. Specifically, this is to facilitate the connection between the two. The connecting piece is a bolt, with two connecting holes at the upper end and one connecting hole at the lower end.

[0025] In the aforementioned adjustable frame structure for a seeder, the locking sleeve 41 has a U-shaped structure and is provided with a second connection hole. Specifically, this is to facilitate the connection between the two, and the locking sleeve is connected to the crossbeam.

[0026] In the aforementioned adjustable frame structure for a seeder, the two ends of the curved beam frame 5 are detachably connected to the left support frame 1 and the right support frame 2, respectively. The curved beam frame 5 includes a curved beam 51, a front support rod 52, and a connecting rod 53. One end of the curved beam 51 is inserted into the connecting pipe 15. The front support rod 52 is connected to the curved beam 51, and the two ends of the connecting rod 53 are provided with connecting plates 54. The front support rod 52 is provided with a fixing plate 55 connected to the connecting plate 54. The fixing plate 55 has an L-shaped structure, which improves the support strength of the fixing plate and ensures the connection stability of the two. The length and width dimensions of the curved beam are smaller than the length and width dimensions of the inner diameter of the connecting pipe, which facilitates the fitting of the two together, and the two are connected together by bolts.

[0027] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
