The feeding groove is movably connected in the inner groove of the strip plate, and an adjustable feeding pipe is provided at the front end of the mounting base plate.

[0004] Regarding the aforementioned technologies, the inventors have discovered at least the following problems: the seeder can only sow one row of wheat seeds at a time, and additional furrowing work is required before sowing, resulting in low sowing efficiency.

[0005] Therefore, we propose an adjustable seeding device for wheat breeding. Utility Model Content

Then, the distance between the two hollow furrowing pipes is adjusted by the second drive component, and the height of the hollow furrowing pipes is adjusted by the first drive component, so that the hollow furrowing pipes extend into the soil.

[0027] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0028] According to the embodiments of this utility model, combined with Figure 1-4 As shown. An adjustable wheat breeding sowing device includes: a sowing frame 1 and a sowing mechanism 2. The sowing mechanism 2 is mounted on the sowing frame 1. A traction frame 11 is fixedly connected to one side of the sowing frame 1. Auxiliary wheels 12 are rotatably mounted at the four corners of the bottom of the sowing frame 1. By setting the sowing frame 1, the traction frame 11 can be connected to agricultural machinery such as tractors. The sowing frame 1 can be moved by the agricultural machinery, and the auxiliary wheels 12 can be used to support the sowing frame 1.

[0029] Specifically, the sowing mechanism 2 includes a support frame 21 slidably installed inside the sowing rack 1, a first drive component 22 for driving the support frame 21 to rise and fall, two support seats 23 symmetrically installed inside the support frame 21, a second drive component 24 for adjusting the distance between the two support seats 23, a hopper 25 fixedly installed on the support seats 23, a hollow furrowing pipe 26 fixedly connected to the bottom of the hopper 25, and an intermittent discharge component 27 disposed at the upper end of the hollow furrowing pipe 26. By setting the sowing mechanism 2, wheat can be simultaneously added to the two hoppers 25 during sowing. Seeds are sown, and then the distance between the two hollow furrowing pipes 26 is adjusted by the second driving component 24, and the height of the hollow furrowing pipes 26 is adjusted by the first driving component 22, so that the hollow furrowing pipes 26 extend into the soil. When the sowing frame 1 drives the sowing mechanism 2 to move along the planting row, the two hollow furrowing pipes 26 can open two rows of planting furrows at the same time. At the same time, the wheat seeds in the hopper 25 are intermittently discharged from the hollow furrowing pipes 26 into the planting furrows through the intermittent discharge component 27, realizing the integration of furrowing and sowing, and realizing the sowing of two rows of wheat seeds at the same time, thus improving sowing efficiency.

[0030] Specifically, the first driving component 22 includes a vertical screw 221 rotatably mounted on one side of the sowing frame 1 and a first motor 222 for driving the vertical screw 221 to rotate. One side of the support frame 21 is sleeved on the vertical screw 221 and threadedly connected to the vertical screw 221. The four corners of the support frame 21 are slidably sleeved on four vertical guide rods 223, and the four vertical guide rods 223 are fixedly mounted at the four corners of the sowing frame 1. By setting the first driving component 22, when adjusting the furrow depth, the first motor 222 can be started to drive the vertical screw 221 to rotate, so that the vertical screw 221 drives the support frame 21 to slide vertically along the vertical guide rods 223, thereby adjusting the height of the hollow furrowing pipe 26 and facilitating the adjustment of the furrow depth.

[0031] Specifically, the second driving component 24 includes a bidirectional screw 241 rotatably installed in the support frame 21 and a second motor 242 for driving the bidirectional screw 241 to rotate. Two support seats 23 are respectively sleeved on both ends of the bidirectional screw 241 and threadedly connected to the bidirectional screw 241. The support seats 23 are slidably sleeved on the transverse guide rod 243, which is fixedly installed in the support frame 21. By setting the second driving component 24, when adjusting the sowing spacing, the second motor 242 can be started to drive the bidirectional screw 241 to rotate, so that the bidirectional screw 241 drives the two support seats 23 to move relative to or in opposite directions along the transverse guide rod 243, thereby adjusting the spacing of the two hollow furrow pipes 26, which is convenient for sowing planting rows with different spacings.

[0032] Specifically, the intermittent discharge component 27 includes a turntable 271 rotatably installed inside the hollow furrow pipe 26 and a third motor 272 for driving the turntable 271 to rotate. Two symmetrically distributed grooves 273 are opened on the outer circumference of the turntable 271. By setting the intermittent discharge component 27, during sowing, the third motor 272 can be started to drive the turntable 271 to rotate, and the wheat seeds in the hopper 25 will fall into the grooves 273. During the rotation of the turntable 271, the wheat seeds in the grooves 273 will be intermittently discharged along the hollow furrow pipe 26 to achieve intermittent sowing.

[0033] In practical use, the working principle of this utility model is as follows:

[0034] First, adjust the spacing between the two hollow trenching pipes 26 according to the spacing of the planting rows. During adjustment, the second motor 242 can be started to drive the bidirectional screw 241 to rotate, so that the bidirectional screw 241 drives the two support seats 23 to move relative to or opposite to each other along the transverse guide rod 243, and adjust the two hollow trenching pipes 26 to a suitable spacing.

[0035] Then, the traction frame 11 can be connected to agricultural machinery such as tractors. The height of the hollow trenching pipe 26 can be adjusted according to the required trenching depth. During adjustment, the first motor 222 can be started to drive the vertical screw 221 to rotate, so that the vertical screw 221 drives the support frame 21 to slide vertically along the vertical guide rod 223, and the hollow trenching pipe 26 can be adjusted to a suitable height.

[0036] Then, the seeding frame 1 can be moved by agricultural machinery, and two rows of planting furrows can be opened simultaneously by the two hollow furrowing pipes 26. At the same time, the third motor 272 can be started to drive the turntable 271 to rotate. The wheat seeds in the hopper 25 will fall into the groove 273. During the rotation of the turntable 271, the wheat seeds in the groove 273 will be intermittently discharged into the planting furrow along the hollow furrowing pipes 26, realizing the integration of furrowing and sowing.

[0037] In summary, this adjustable wheat breeding sowing device, by setting up the sowing mechanism 2, achieves integrated furrow sowing and simultaneously sowing two rows of wheat seeds, thereby improving sowing efficiency.

[0038] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
