[0032] Embodiment 1

[0033] A corn no-tillage seeder, which structure is shown in Figure 1 、 Figure 3 The corn no-tillage seeder comprises a rack 1 with wheels, a bin 2 arranged on the top of the rack 1, a motor 3 arranged at the bottom of the bin 2, a discharging assembly 4 arranged at the bottom of the bin 2 and in transmission connection with the motor 3, and a seeding assembly 5 arranged at the discharging end of the discharging assembly 4.

[0034] The seeding assembly 5 comprises a fixed tube 51 in communication with the discharging end of the discharging assembly 4.

[0035] A dial plate 53 in transmission connection with the motor 3 to drive the sliding tube 52 to move downward.

[0036] Wherein, the opposite surfaces of the dial plate 53 and the sliding tube 52 are both provided with a section of gear teeth 55 capable of engaging with each other.

[0037] The fixed tube 51 is arranged downwardly inclined along the advancing direction of the seeder.

[0038] The lower end surface of the sliding tube 52 is configured as an inclined surface so that the lower end surface is lowest on the side close to the advancing direction.

[0039] In actual application, the bin 2 contains two independent and separated holding spaces for holding fertilizers and corn seeds respectively; the discharging assembly 4 and the seeding assembly 5 are correspondingly configured as two groups for scattering fertilizers and corn seeds respectively; the elastic member 54 is configured as a spring, and its two ends are respectively fixed to the fixed tube 51 and the end of the sliding tube 52 close to the discharging assembly 4; the dial plate 53 is configured as a disc, and its outer edge is provided with a section of gear teeth 55 protruding from other surfaces to engage with the surface of the sliding tube 52; the wheels are in transmission connection with the motor 3 to ensure the consistency of seeding speed and distance.

[0040] Working principle: when sowing, the sowing machine moves forward, and the poking disc 53 rotates under the drive of the motor 3. When the gear teeth 55 of the poking disc 53 are close to the sliding pipe 52, the gear teeth 55 of the two are engaged, the poking disc 53 drives the sliding pipe 52 to slide downward, until the sliding pipe 52 is inserted into the soil by a certain distance; at the same time, the fertilizer and corn seeds in the material box 2 are respectively guided through the corresponding fixed pipe 51 and sliding pipe 52 under the cooperation of the discharging assembly 4, and finally fall into the corresponding sliding pipe 52 in the inclined groove formed in the soil in front of the sliding pipe 52 under the inertia, the process of the material falling into the inclined groove is similar to the automatic sowing hoe; then, the gear teeth 55 are completely separated, the poking disc 53 no longer pokes the sliding pipe 52 to move, and the sliding pipe 52 moves upward quickly under the drive of the spring and returns to the original position and separates from the soil. Because the sliding pipe 52 is inclined to the forward direction, when the lower end of the sliding pipe 52 is pulled out of the soil, the soil falling can basically cover the inclined groove formed by the sliding pipe 52, and the covering is completed. The forward moving sowing machine can complete the sowing and fertilizing work.

[0041] By setting the sliding pipe 52 inclined to the forward direction, and making the lower end surface of the sliding pipe 52 inclined, under the drive of the poking disc 53, the lower end of the sliding pipe 52 moves forward and inserts into the soil, and the seeds and fertilizers are left in the soil; when the poking disc 53 is not forced, the elastic member 54 quickly drives the sliding pipe 52 to return to the original position, and after the lower end of the sliding pipe 52 is pulled out of the soil, the soil lifted upward by the sliding pipe 52 falls and can basically cover the inclined groove formed by the sliding pipe 52, and the soil needs to be covered additionally to cover the seeds, complete the covering, and reduce the subsequent work.

[0044] Working principle: the guide pipe 56 is set to guide the movement of the sliding pipe 52, avoid the deviation of the movement track of the sliding pipe 52, cause the damage of the components, and improve the stability of the device.

[0045] Embodiment 3

[0046] This embodiment 3 is a preferred embodiment of the utility model, and the specific structure is as shown in Figure 2 The material box 2 is provided with a rotating shaft 6 in transmission connection with the motor 3;

[0047] The rotating shaft 6 is provided with a poking blade 61 for stirring the materials in the material box 2;

[0048] The toggle blade 61 is arranged close to the discharge port of the hopper 2.

[0049] In actual application, the rotating shaft 6 penetrates through two parallel holding spaces of the hopper 2, and the toggle blade 61 is arranged in both holding spaces; the outer edge of the toggle blade 61 is provided with a flexible layer.

[0050] Working principle: when working, the rotating shaft 6 drives the toggle blade 61 to stir the material in the holding space, so as to avoid the material in the hopper 2 from blocking the discharge port and causing poor discharging; meanwhile, the flexible layer can scrape away the excess material without damaging the material, so as to facilitate the batch delivery of the discharging assembly 4 and avoid the material from blocking the discharge port of the hopper 2.
