[0024] Depend on Figures 1 to 8 It can be seen that a wheat seeder includes a frame 1, a seed box 2 is arranged above the frame 1, the bottom of the seed box 2 is conical and has multiple discharge ports 3, the bottom of the seed box 2 is provided with multiple discharge modules located at the bottom of the discharge ports 3, the bottom of the discharge module is connected with a ditching module, the position of the multiple ditching modules at the bottom of the seed box 2 can be adjusted and the spacing can be kept the same, the frame 1 is provided with an active shaft 4 for driving the multiple discharge modules, a first adjusting shaft 5 for adjusting the position of the ditching module and a second adjusting shaft 6 for adjusting the sowing amount of the discharge module, the first adjusting shaft 5 can adjust the wheat sowing spacing, the second adjusting shaft 6 can adjust the wheat sowing amount, and the active shaft 4 can drive the discharge module to realize wheat sowing.

[0025] When the present invention is used in a specific manner, Add wheat seeds into the seed box 2, move the equipment to the planting site, adjust the wheat planting spacing and sowing amount according to the site requirements, start the equipment, and the frame 1 moves under the action of the traction mechanism. During the movement, the active shaft 4 drives the feeding module to operate, so that the wheat is sown.

[0026] In the present invention, a plurality of running wheels 7 are provided at the bottom of the frame 1 for supporting the frame 1 during sowing to keep the equipment balanced.

[0027] In the present invention, a connecting frame 8 is provided at the front end of the frame 1, and the connecting frame 8 is used to connect the frame 1 to a traction mechanism, and the traction mechanism enables the frame 1 to move to complete wheat sowing.

[0028] In the present invention, slide grooves 9 are provided on both sides of the bottom of the seed box 2, and the trenching module includes a shell 10 sliding in the slide groove 9, the upper end opening of the shell 10 corresponds to the discharge port 3, the opening size of the shell 10 is larger than the size of the discharge port 3, the discharge module is rotatably connected to the shell 10, a discharge pipe 11 is provided at the bottom of the shell 10, a trencher 12 is provided at the front end of the bottom of the discharge pipe 11, an auxiliary ring 13 is provided on the discharge pipe 11, an auxiliary rod 14 is provided on the frame 1, and the auxiliary ring 13 is sleeved on the auxiliary rod 14.

[0029] When adjusting the spacing of the feeding modules, the position of the feeding modules changes. After the position adjustment is completed, the auxiliary ring 13 is locked on the auxiliary rod 14 to fix its position. After the position of the feeding module is adjusted, since the opening size above the shell 10 is larger than the size of the feeding port 3, the wheat seeds can be guaranteed to fall smoothly.

[0030] In the present invention, the feeding module includes a feeding shaft 15, one end of the feeding shaft 15 is an optical axis, and the other end of the feeding shaft 15 is a plum blossom axis. One side of the shell 10 is slidably and rotatably connected to the optical axis, and the other side of the shell 10 is slidably and rotatably connected to the plum blossom axis; the feeding shaft 15 is slidably connected to the driving shaft 4 to ensure that the feeding shaft 15 and the driving shaft 4 rotate synchronously. At the same time, the feeding shaft 15 can be fine-tuned in the shell 10 to achieve adjustment of the sowing amount, and after the position of the feeding shaft 15 is adjusted, it still maintains a rotational connection with the shell 10 and the inside of the shell 10 is sealed, so that wheat seeds will not fall.

[0031] One side of the shell 10 is slidably connected to the optical axis via a bearing, and the other side of the shell 10 is rotatably connected to a plum blossom sleeve slidably connected to the plum blossom shaft, which not only realizes the rotation of the blanking shaft 15 and the shell 10, but also enables the movement of the blanking shaft 15 in the shell 10.

[0032] In the present invention, a threaded sleeve 16 is rotatably provided on the outer side of the housing 10, and the interior of the threaded sleeve 16 is slidably connected to the second adjustment shaft 6. An external thread is provided on the outer side of the threaded sleeve 16. A connecting plate 17 threadedly connected to the threaded sleeve 16 is rotatably connected to one end of the upper optical axis of the feed shaft 15. The second adjustment shaft 6 rotates to move the feed shaft 15 in the housing 10 to adjust the wheat sowing amount. The second adjustment shaft 6 rotates to rotate the threaded sleeve 16. The threaded sleeve 16 rotates to move the connecting plate 17 outside the threaded sleeve 16, driving the feed shaft 15 to move in the housing 10 to adjust the wheat sowing amount. A second adjustment handle 26 connected to the second adjustment shaft 6 is provided on the side of the frame 1.

[0033] The second adjusting shaft 6 is slidably connected to the threaded sleeve 16, so that synchronous rotation can be achieved, and the threaded sleeve 16 can slide on the second adjusting shaft 6 to achieve adjustment of the wheat planting spacing.

[0034] In the present invention, a sleeve 18 is provided on the outside of the shell 10, and the sleeve 18 cooperates with the first adjusting shaft 5 to adjust the position of the unloading module. The first adjusting shaft 5 includes a first shaft 19 rotatably connected to the sleeve 18 of the middle unloading module, and both ends of the first shaft 19 are threadedly connected to the sleeve 18 of the adjacent unloading module. A second shaft 20 is passed through both ends of the first shaft 19, one end of the second shaft 20 is rotatably connected to the unloading module, and the other end of the second shaft 20 is threadedly connected to the sleeve 18 of the adjacent unloading module. A first adjusting handle 21 is provided on the frame 1 and is sleeved with the second shaft 20. Rotating the first adjusting handle 21 causes the first shaft 19 and the second shaft 20 to rotate synchronously, so that the positions of adjacent unloading modules are adjusted and the spacing is kept the same.

[0035] By rotating the first adjustment handle 21, the first axis 19 and the second axis 20 of the first adjustment axis 5 rotate synchronously. The sleeve 18 adjacent to the middlemost feeding module is threadedly connected to the first axis 19. When the first axis 19 rotates, the distance between the sleeve 18 and the middlemost feeding module changes, and the second axis 20 is driven to move at the same time. The rotation of the second axis 20 causes the distance of the sleeve 18 threadedly connected to the second axis 20 to change relative to the feeding module rotatably connected to the second axis 20. The first axis 19 and the second axis 20 have the same pitch and rotate synchronously. Therefore, the distance change between adjacent feeding modules always remains the same, that is, the distance between adjacent feeding modules is always the same, that is, the sowing spacing of wheat is always the same.

[0036] The first shaft 19 has first hexagonal columns 22 extending from both ends, one end of the second shaft 20 is provided with a hexagonal hole 23 matching with the first hexagonal column 22, and the other end of the second shaft 20 has a second hexagonal column 24 extending from the other end for transmission matching with the adjacent second shaft 20. The first shaft 19 is rotationally connected at the middle position, and the two ends of the first shaft 19 cooperate with the hexagonal hole 23 of the second shaft 20 through the first hexagonal prism 22 to realize a synchronous rotation connection structure, and the second shaft 20 is rotationally connected to the blanking module. Therefore, during the adjustment of the position of the blanking module, the first hexagonal prism 22 will be telescoped inside the hexagonal hole 23, and the first shaft 19 and the second shaft 20 can achieve telescopic adjustment while maintaining synchronous rotation. Similarly, the second hexagonal prism 24 at the end of the second shaft 20 can cooperate with the hexagonal hole 23 of the adjacent second shaft 20 to complete the transmission cooperation.

[0037] In the present invention, a drive motor 25 is provided on the frame 1, and the drive motor 25 drives the active shaft 4 to rotate. The rotation speed of the drive motor 25 matches the travel speed of the frame 1. The drive motor 25 may also be not provided, and the active shaft 4 is connected to the walking wheel 7 through a chain, thereby ensuring that the wheat sowing amount is adapted to the travel distance, thereby ensuring the accuracy of the sowing amount.

[0038] Compared with the prior art, the present invention has the following beneficial effects: The plant spacing of wheat sowing can be adjusted. Multiple feeding modules are adjusted synchronously to keep the spacing equal. The feeding module and the furrowing module maintain a stable relative position during the position adjustment process. The active shaft and the second adjustment shaft are connected by sliding to achieve position adjustment while keeping the transmission relationship unchanged, ensuring accurate adjustment and smooth subsequent sowing. The wheat sowing amount can be adjusted, and multiple feeding modules can be moved in the furrowing module shell to adjust the corresponding wheat sowing amount. Multiple feeding modules can be adjusted synchronously to ensure the stability and uniformity of the wheat sowing amount, thereby ensuring that the wheat grows under more favorable conditions to maximize the wheat yield.
