[0024] Specifically, the seeds to be sown are poured into the storage box 2, and the position of the tooth group 6 on the distance disk 4 is adjusted and fixed according to the seed sowing spacing. When multiple tooth groups are needed, the number of fixed tooth groups 6 is increased, and the seeder moves forward. The furrowing plow 11 furrows the soil, and the walking wheel 3 drives the distance disk 4 to rotate. The tooth group 6 on the distance disk 4 engages with the gear 10, so that the through shaft 9 rotates, and the through shaft 9 links the seed feeder 8 to discharge the material, and the sowing is completed.

[0025] In one embodiment of the present application, preferably, a sliding seat 12 is connected to the frame 1 for transverse sliding movement, a sliding tube 13 is connected to the sliding seat 12 for vertical sliding movement, the bottom end of the sliding tube 13 is fixedly connected to the furrowing plow 11, and a soil covering mechanism is rotatably connected to the sliding seat 12. The soil covering mechanism is two front and rear soil covering plates 14 inclined outwardly. The spacing of the sliding seats 12 is adjusted laterally according to the seed row spacing requirements, and the height of the sliding tube 13 is adjusted according to the sowing depth requirements. The soil covering plates 14 are used to cover the soil turned over by the furrowing plow 11 on the seeds after sowing. The two front and rear plates inclined outwardly are not closed to prevent the soil covering plates 14 from scraping away the soil and affecting the soil covering effect. The soil covering plates 14 are provided with a connecting rod rotatably connected to the sliding seat 12 to adapt to various soil hardnesses.

[0026] In one embodiment of the present application, preferably, a plurality of brackets 15 are provided on the frame 1, and a winding wheel 16 is rotatably connected to the bracket 15. A steering wheel 17 is provided at the top of the sliding tube 13 and under the furrowing plow 11. When the seed particles are small and spot planting is impossible, the line sowing technology is adopted. The bracket 15 is used to support the winding wheel 16 for winding the seed belt. Before sowing, the seed belt is turned from the steering wheel 17 at the top of the sliding tube 13 to pass through the inner cavity of the sliding tube 13 to reach under the furrowing plow 11, and is turned horizontally by the steering wheel 17 under the furrowing plow 11 and buried in the soil, so that the machine is suitable for the seed requirements of line sowing, making the applicability of the machine higher.

[0027] In one embodiment of the present application, preferably, the distance plate 4 is provided with a through hole 18 at the position of the tooth groove 5 , and a fixing bolt 19 is installed in the through hole 18 for fixing the tooth set 6 on the distance plate 4 .

The center of the round roller 81 is fixedly connected to the through shaft 9. When the through shaft 9 rotates, the round roller 81 is driven. The metering groove 82 on the round roller 81 is filled with seeds dropped from the discharge pipe 7. When the metering groove 82 rotates to the discharge pipe 7 under the seed feeder 8, the seeds in the metering groove 82 flow out from the discharge pipe 7.

[0029] In one embodiment of the present application, preferably, the bottom end of the feed pipe 7 is fixed to the tail end of the furrowing plow 11 to facilitate the seeds to fall into the furrow, and also allows the bottom end of the feed pipe 7 to move left and right with the furrowing plow 11.

[0030] In one embodiment of the present application, preferably, the ratio of the length of the tooth set 6 to the circumference of the distance disk 4 is consistent with the ratio of the size of the metering groove 82 to the circumference of the round roller 81, so that running one tooth set 6 can cause the round roller 81 to rotate one metering groove 82 position to complete one sowing.

[0031] In one embodiment of the present application, preferably, the bracket 15 is Y-shaped, and the adjacent upper and lower layers are arranged alternately, so that the size of the winding wheel 16 can meet the requirements of line broadcasting.

[0032] In summary, the crop sowing device in the above embodiment of the utility model specifically adjusts the spacing of the sliding seat 12 laterally according to the seed row spacing requirements, adjusts the height of the sliding tube 13 according to the sowing depth requirements, pours the seeds to be sown into the storage box 2, adjusts the position of the tooth group 6 on the fixed distance plate 4 according to the seed sowing spacing and fixes it, and increases the number of fixed tooth groups 6 when more are needed, so that the seeder moves forward, the furrowing plow 11 furrows the soil, the walking wheel 3 drives the fixed distance plate 4 to rotate, and the tooth group 6 on the fixed distance plate 4 meshes with the gear 10, so that the through shaft 9 rotates, The through shaft 9 drives the round roller 81 in the seed feeder 8 to rotate, and the seeds in the quantitative groove 82 fall into the ditch along the tube at the feeding tube 7 at the bottom of the seed feeder 8. The soil cover 14 scrapes the soil turned up by the furrowing plow 11 onto the seeds to complete the sowing. When the seed particles are too small, the line sowing technology is used, and the winding wheel 16 wrapped with the seed belt is placed on the bracket 15. Before sowing, the seed belt is turned from the steering wheel 17 at the top of the sliding tube 13 to pass through the inner cavity of the sliding tube 13 to reach the furrowing plow 11, and is turned horizontally by the steering wheel 17 under the furrowing plow 11 and buried in the soil. This device is suitable for spot sowing of large seed particles and line sowing of small seed particles. It is suitable for sowing at various spacings, meets the precision sowing requirements of crops, reduces seed waste, improves sowing efficiency, and improves the utilization rate of machinery.
