[0025] It should be noted that eight groups of furrowing wheels 3 are used in the embodiment, and eight land wheels 4 are also used for covering soil after seeding.

[0026] The adjusting assembly comprises two tooth plates 11 and a limiting plate 18. The top of each tooth plate 11 is provided with a corresponding groove, and a lifting ring 1101 is arranged between the two tooth plates 11. The two ends of the lifting ring 1101 are fixedly connected with protrusions, which can be embedded in the grooves. The two tooth plates 11 are fixed on the bottom of the rack 2 through a mounting plate 1103, and the tooth plates 11 are located at the front end of the support column 6. The limiting plate 18 is also fixedly connected to the bottom of the rack 2 and located between the tooth plates 11 and the support column 6. The bottom of the lifting ring 1101 is connected with one end of a spring 1102, and the other end of the spring 1102 is connected with the lower part of the support column 6. The limiting plate 18 is in close contact with the support column 6, and a rubber pad can be arranged between the limiting plate 18 and the support column 6, for example, the rubber pad is fixedly connected to the side of the limiting plate 18 close to the support column 6, or the rubber pad is fixedly connected to the side of the support column 6 close to the limiting plate 18. In this way, when the furrower 3 encounters a hard object and returns, the rubber pad can provide a buffer, reduce the impact force of the limiting plate 18 and the returning support column 6, protect the device to a certain extent, increase the service life of the device, and adjust the position of the lifting ring 1101 to adjust the tension of the spring 1102, so that the support column 6 can quickly restore to the vertical state after encountering a hard object, and the furrowing effect of the furrower 3 is ensured.

[0027] The cleaning assembly comprises a connecting plate 16 and spring teeth 17.

The bottom end of the connecting plate 16 is detachably connected with a plurality of spring teeth 17 through bolts, which is convenient for subsequent maintenance and replacement. In order to better clean the mulch residues on the seeding route, the spring teeth 17 can be correspondingly arranged at the front end of the furrower 3.

[0028] In order to reduce the impact force of the support column 6 on the limiting plate 18 when the support column 6 returns, a rubber pad 1801 is fixedly connected to the rear end of the limiting plate 18, which can absorb part of the impact force and avoid the deformation caused by the impact of the support column 6 and the limiting plate 18, thereby increasing the service life of the equipment.

[0029] The support column 6 and the discharge pipe 10 are fixedly connected through a fixing plate 1002.

[0030] In order to avoid the occasional mixing phenomenon of seeds and fertilizers during discharging, a blocking ring is arranged in the center of the discharging wheel 901.

[0031] In order to increase the stability of the partition plate 8, a reinforcing rod 801 is fixedly connected between the top of the partition plate 8 and the seed and fertilizer bin 1.

[0032] In order to facilitate the recycling of the corn seeds and fertilizers that are not used in the seed and fertilizer bin 1, a surplus outlet 15 is arranged on one side of the seed and fertilizer bin 1. The surplus outlet 15 can be provided with two channels corresponding to the two sides of the partition plate 8, which facilitates classified recycling.

[0033] The working process of the embodiment is as follows:

[0034] When seeding, the silage corn seeds and the fertilizer are respectively put into the seed and fertilizer bin 1 on both sides of the partition plate 8, and then the seeding device is connected with the rear suspension of the tractor through the hinge seat 1401 on the connecting arm 14. When starting seeding, the V-shaped arrangement of the furrowing wheel 3 is responsible for furrowing, and due to its circular structure, a soil beam is left in the center of the furrow. The sprocket on the support wheel 5 drives the sprocket on the main shaft 12 to rotate through the chain, thereby driving the seed wheel 901 to rotate, so as to respectively sow the corn seeds and the fertilizer from the discharge port 101 on both sides of the partition plate. The seeds and the fertilizer respectively pass through the hose 1001 and the discharge pipe 10, and finally fall into the soil beam on both sides of the furrow, preventing the direct contact between the fertilizer and the seeds, which may cause damage to the corn seeds. Then, the flat ground is covered by the land leveler 4 to complete the seeding. During the seeding, if the furrowing wheel 3 encounters relatively hard substances in the soil, such as stones, or uneven terrain, the furrowing wheel 3 at the bottom of the support column 6 will move backward to avoid a violent collision with hard objects and cause damage to the device. Then, the support column 6 will be reset by the spring 1102, and the furrowing wheel 3 will be reset until the support column 6 is on the limiting plate 18 on the front side, so that it continues to maintain the vertical state. The spring teeth 17 at the front end of the frame 2 will clean the residual film on the seeding route. For small pieces of residual film, they will be pushed to both sides to avoid the presence of film on the seeding route, which may affect the seed germination. After completing the seeding, the excess corn seeds and fertilizer can be conveniently recycled through the excess material outlet 15. When maintaining the device, if the spring stiffness coefficient is found to be decreased, the position of the corresponding lifting ring 1101 can be adjusted to continue stretching the spring and increase the tension, so as to ensure that the support column 6 can be reset in time and ensure the furrowing effect.
