Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of agricultural machinery, and relates to a seeding machine technology, in particular to a wheat strip uniform seeding and furrowing rotary tillage assembly. BACKGROUND

[0002] The formation of wheat yield depends on the coordination of individuals and groups. A good group structure should be beneficial to the development of each individual. In the development process of the wheat group, each individual in the group is ventilated and lighted, the individual develops healthily, and the disease is prevented and the plant is prevented from falling, which is the basis for high yield of wheat. The distance between the individuals of wheat is an important factor affecting the growth and development of the plant, and the planting density and the seeding amount must be appropriate. When wheat is seeded, increasing or decreasing the seeding amount and changing the row distance are one of the main measures of artificial regulation.

[0003] The ideal state of seeding should effectively expand the seeding row width, optimize the row distance, uniformly distribute the grains, and have no grain crowding phenomenon. The seeding position of the wheat seeds should be uniformly distributed, which can form a uniform and consistent light, temperature, water and fertilizer growth environment, and can also maintain good ventilation and light conditions.

[0004] The existing wheat seeding is mainly based on a seeding machine, and the structures of the wheat seeding mechanisms are basically the same, mainly composed of a rack, a seed box, a rotary tillage knife, a seed metering device, a fertilizer distributor, a press wheel, a blower, a transmission device and the like. In the seeding process, the wheat seeding machine has the problems of narrow seeding width, uneven seed distribution, and the like, which is not conducive to the wide and dense planting of wheat for high yield. The main reason is that the wheat seeds roll down from the seed guide pipe, the rebounding force of the wheat seeds impacting the seed scattering reflection plate is small, the wheat seeds rebound and directly slide down, are affected by the friction force, the falling trajectory of the wheat seeds is changed, directly slide into the seed bed, the seeds are concentrated in the middle of the seeding band, the seeds are less on both sides of the seeding band, the seeds are unevenly distributed, and the seeding width is generally less than 120 mm.

[0005] In the prior art, as shown in Figure 5 , 6 , the arrow in the figure represents the falling trajectory of the wheat seeds, the bottom outlet of the seed guide pipe is directly opposite to the inclined bottom plate 11, the bottom plate 11 forms an angle of 40-60° with the horizontal plane, the wheat seeds fall and impact the inclined bottom plate 11, bounce upward and throw forward at the same time, bounce slightly or directly slide down along the bottom plate 11 after falling on the bottom plate 11 for the second time, and finally slide down along the bottom plate 11 on the original trajectory, directly slide into the seed bed from the bottom plate 11, and the seeds fall into the soil plane 9 of the seed bed. The rolling distance of the seeds on the seed bed is 15-20 cm, the seeds are concentrated in the middle of the seeding band, the seeds are less on both sides of the seeding band, the seeds are unevenly distributed, and the seeding quality is affected.

[0006] Institute of Geographic Science and Natural Resources, Chinese Academy of Sciences discloses a wheat wide seed ridge strip seeding machine in patent application CN102845166A, a plurality of protrusions are arranged in the cavity of the furrow opener in the preferred embodiment, which solves the problem that the seeds sown by the furrow opener form a line and cannot form a strip of wide seed ridge due to the certain distance between the adjacent furrow openers; however, it is found through practice that the arrangement of the protrusions in the cavity of the furrow opener not only reduces the falling speed of the wheat seeds, causes the seeds to fail to continue to roll in the seedbed, affects the rolling distance of the seeds in the seedbed, but also easily causes the seed coat of the wheat seeds to be damaged, affects the quality of the seeds, and more importantly, the protrusions cannot accurately solve the problem of uneven seeds.
