[0002] When sowing corn, a seeder is needed. The operation of existing sowing mechanisms is often relatively simple, and some cannot achieve fixed-distance sowing, resulting in uneven seed distribution, affecting the growth and yield of crops. Some devices that can sow at fixed distances have complex structures, which increases the cost of use. In addition, for the mixing of corn seeds and fertilizers, traditional sowing methods require separate operating steps, which increases the complexity of the operation and the working hours.

[0005] Furthermore, a discharge pipe communicating with the sowing hole is provided at the bottom of the sowing cylinder.

[0006] Furthermore, the bottom of the frame is provided with a soil-breaking plate located on one side of the transmission mechanism, and the bottom of the frame is provided with a soil-collecting plate located on the other side of the transmission mechanism.

[0007] Furthermore, the frame is provided with a handle located on one side of the sowing cylinder.

[0008] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0009] The utility model has the following beneficial effects:

[0010] When the wheel rotates, it drives the transmission rod to rotate, drives the second bevel gear to rotate, and then drives the first bevel gear meshed with it to rotate, further drives the stirring shaft to rotate. When the stirring shaft rotates, it drives the stirring blades to rotate, stirring the corn seeds and the required fertilizer in the sowing barrel to prevent the fertilizer from sticking and uneven attachment of the fertilizer, and simultaneously drives the sowing plate to rotate, driving the seeds and fertilizer entering the discharge hole to rotate. When they coincide with the sowing hole, the seeds and fertilizer fall into the soil layer broken by the soil-breaking plate through the discharge pipe, thereby completing the sowing; the device has a simple structure and is easy to operate. It completes the fixed-distance sowing of corn seeds by setting a plurality of equally spaced discharge holes. The fertilizer and seeds are stirred by the stirring blades, which reduces the complexity and working hours of the operation and can also prevent the fertilizer from sticking.

DETAILED DESCRIPTION

[0019] See also Figures 1 to 7A corn seeder includes a frame 1, a sowing mechanism 2 provided on the frame 1 and a transmission mechanism 3 provided at the bottom of the frame 1. The sowing mechanism 2 includes a sowing barrel 4, a sowing disc 5 and a stirring blade 6. The sowing barrel 4 is provided on the frame 1. A sowing hole 7 is provided at the bottom of the sowing barrel 4. A plurality of discharge holes 8 are provided at equal intervals in the circumference of the sowing disc 5. The sowing disc 5 abuts against the bottom of the sowing barrel 4. The stirring blade 6 is located in the sowing barrel 4 and above the sowing disc 5. The bottom of the stirring blade 6 is connected to a stirring shaft 9, which is connected to the bottom of the sowing barrel 4 through a bearing. 9 is connected to the seeding plate 5, one end of the stirring shaft 9 extends to the outside of the seeding barrel 4 and is connected to the first bevel gear 10, the transmission mechanism 3 includes a transmission rod 12, a second bevel gear 13 and a wheel 14, the transmission rod 12 is hinged to the bottom of the frame 1, the second bevel gear 13 is provided on the transmission rod 12 and meshes with the first bevel gear 10, and a group of wheels 14 are respectively provided at both ends of the transmission rod 12. The rotation of the wheel 14 drives the second bevel gear 13 to rotate, the second bevel gear 13 drives the first bevel gear 10 to rotate, and the first bevel gear 10 drives the seeding plate 5 and the stirring blade 6 to rotate synchronously.

[0020] in,

[0021] The bottom of the frame 1 is provided with a breaking plate 16 located on one side of the transmission mechanism 3, and the bottom of the frame 1 is provided with a collecting plate 17 located on the other side of the transmission mechanism 3.
