In this specific embodiment, as shown in FIG. 1, the tridimensional uniform seeder for wheat further includes a first screw shaft 11, where the first screw shaft 11 is disposed obliquely above the press wheel 10, and the first screw shaft 11 is in contact with the surface of the press wheel 10 or a first gap is left therebetween, and further includes a second screw shaft 13, where the second screw shaft 13 meshes with the first screw shaft 11, and a part where the first screw shaft 11 meshes with the second screw shaft 13 is located under the higher end of the conveyor belt 7; and the rotation speeds of the first screw shaft 11 and the second screw shaft 13 are higher than the rotation speed of the press wheel 10. Through the mesh rotation of the first screw shaft 11 and the second screw shaft 13, the soil falling from the conveyor belt 7 is squeezed, the soil clods in the soil are further reduced, so that the thickness and compactness of the soil compacted by the compaction wheel 12 are more uniform, and thus the uniformity of the growth and development of wheat seeds is increased, and in turn the yield is improved.

A fertilizer pipe 3 communicates with the bottom of the fertilizer box 2. The framework 1 is provided with a fertilizer baffle 4, the fertilizer baffle 4 is located under a lower end of the fertilizer pipe 3, and one

2019100054 18 Jan 2019 end of the fertilizer baffle 4 is inclined downwards. Fertilizers dropped from the fertilizer box 2 are more dispersed by the collision of the fertilizer baffle 4, and the fertilizers are more uniformly dispersed on the soil, so that uneven growth of the wheat seedlings caused by uneven fertilization can be avoided.

The rotary blade set includes a plurality of sets of rotary blades 5 and a plurality of sets of cross blades 6, and the cross blades 6 are disposed between two adjacent sets of rotary blades 5. During the rotary tillage, the straws are often wound on the rotary blades 5, and the setting of the cross blades 6 can reduce the entanglement of the straws to the rotary blades 5.

The seed box includes a first chamber 14 for accommodating seeds, the lowest end of the first chamber 14 is provided with a seed outlet, a first seed baffle 9 inclined downwardly is disposed below the seed outlet, and a lower end of the first seed baffle 9 is located at one side of a seeding port; the other side of the seeding port is provided with a second seed baffle 8, and a lower end of the second seed baffle 8 is lower than the lower end of the first seed baffle 9. After falling from the seeding port, the seeds are distributed more uniformly by the collision of the first seed baffle 9 and the collision of the second seed baffle 8, so that the accumulation of multiple seeds on the ground is avoided, and thus the seeding is more uniform.

The framework 1 is provided with a gearbox, and a power input end of the gearbox is dynamically connected to a tractor, and a power output end of the gearbox is dynamically connected to the fertilizer box 2, the rotary blade set, the conveyor belt 7, the seed box, the press wheel 10, the first screw shaft 11, the second screw shaft 13 and the compaction wheel 12 through chains.

The scraper plate 15 is a curved plate or a flat plate structure, and the lower side thereof can be set in a zigzag shape, and the scraper plate 15 is in contact with the press wheel 10 through the zigzag structure. During the rotation of the press wheel 10, the scraper plate 15 scrapes off the soil adhered to the surface of the press wheel 10.

By means of the tridimensional uniform seeder for wheat in this embodiment, the fertilization is more uniform through the seed baffle; the entanglement of the straws to the rotary blades 5 is reduced by matingly using the cross blades 6 and the rotary blades 5; the seed baffle 9 and the second baffle 8 on the seed box make the seeding more uniform; the rotation of the first screw shaft 11 causes the surface of the press wheel 10 to no longer adhere to the soil, so that the pressed ground is more flat, so that the seeding depth is consistent; the soil is further pulverized by the mesh rotation of the first screw shaft 11 and the second screw shaft 13, so that the thickness of the covering soil after seeding is consistent, and the compaction wheel 12 can make the compactness and thickness of the compacted covering soil more uniform, so that the seeding depth is more consistent.

Under the premise that the tridimensional uniform seeder for wheat in this embodiment has achieved

2019100054 18 Jan 2019 a more uniform fertilization and seeding, a more uniform seeding depth, and a more consistent soil compactness after compaction, the yield per unit area of wheat can be increased by about 5-10%.
