DETAILED DESCRIPTION

[0028] Embodiment 1

[0029] Reference Figure 1-3 An agricultural corn automated planting machine comprises a base plate 1, two symmetrically distributed support plates 2 are fixedly connected to one end of the bottom surface of the base plate 1, the lower ends of the two support plates 2 are rotatably connected to a wheel axle 3 through bearings, both ends of the wheel axle 3 are coaxially fixedly connected to a moving wheel 4, two symmetrically distributed support legs 5 are fixedly connected to one end of the bottom surface of the base plate 1 away from the moving wheel 4, the lower end of each support leg 5 is rotatably connected to an auxiliary wheel 6 through a pin shaft, a chassis 7 is fixedly connected to the base plate 1, and a push handle 33 is fixedly connected to the side of the base plate 1 close to the auxiliary wheel 6.

[0030] A seed groove 8 and a fertilizer groove 9 are provided on the chassis 7, and the seed groove 8 is close to the push handle 33. The lower end of the chassis 7 is separately provided with a slide groove 10 that runs through both ends of the chassis 7. A slide plate 11 is slidably connected in the slide groove 10. A plurality of discharge holes 12 are evenly spaced at the bottom of the seed groove 8 and the fertilizer groove 9 and are connected to the slide groove 10. A plurality of seed holes 14 and a plurality of fertilizer holes 15 are evenly spaced on the slide plate 11. The bottom of the chassis 7 and the bottom plate 1 are jointly provided with a first discharge groove 131 and a second discharge groove 132 that are connected to the slide groove 10.

[0031] The positions of the first feeding trough 131 and the second feeding trough 132 and the feeding hole 12 are staggered. A plurality of double-layer sowing tubes 16 are fixedly connected to the bottom surface of the base plate 1. The inner tube of each double-layer sowing tube 16 is communicated with a plurality of second feeding troughs 13 respectively. A guide tube 18 is fixedly connected to the bottom surface of the base plate 1 at each first feeding trough 131. The lower end of each guide tube 18 is connected to the outer tube of the adjacent double-layer sowing tube 16. An annular guide plate 17 is fixedly connected to the lower end of each double-layer sowing tube 16. The number of feeding holes 12 is the same as the total number of the first feeding trough 131 and the second feeding trough 132. The structural setting of the annular guide plate 17 can gather the seeds dropped from the inner tube of the double-layer sowing tube 16, and scatter the fertilizer dropped from the outer tube of the double-layer sowing tube 16 to the surroundings, so that the fertilizer is distributed in the soil around the seeds after sowing, thereby avoiding the burning of seeds and seedlings.

[0032] The end of the bottom plate 1 away from the push handle 33 is fixedly connected to the bracket 19, and the top center position of the bracket 19 is rotatably connected to the rotating shaft 20 through a bearing, the upper end of the rotating shaft 20 is coaxially fixedly connected to the driven friction wheel 21, and the lower end of the rotating shaft 20 is coaxially fixedly connected to the turntable, and the eccentric position of the bottom surface of the turntable is rotatably connected to the connecting rod 22 through a pin shaft, and the end of the connecting rod 22 away from the turntable is rotatably connected to the end of the slide plate 11 close to the bracket 19 through a pin shaft, and the bottom of the bottom plate 1 is fixedly connected to two symmetrically distributed fixed plates 23 at one end of the bracket 19, and the upper ends of the two fixed plates 23 are rotatably connected to the main shaft 24 through bearings, and the main shaft 24 is provided with a threaded section 2 near the upper part of the driven friction wheel 21 5. Two moving grooves 26 are provided on the main shaft 24 at the threaded section 25. An active friction wheel 27 is coaxially provided on the main shaft 24. The active friction wheel 27 is slidably connected to the two moving grooves 26. Two positioning nuts 28 are threadedly connected to the threaded section 25. The two positioning nuts 28 are respectively arranged on both sides of the active friction wheel 27. The active friction wheel 27 is connected to the driven friction wheel 21 through friction transmission. One end of the wheel shaft 3 is coaxially fixedly connected to the active wheel 34. One end of the main shaft 24 close to the active wheel 34 is coaxially fixedly connected to the driven wheel 35. The active wheel 34 and the driven wheel 35 are jointly sleeved with a transmission belt, which connects the sowing distance with the movement of the seeder, so as to realize uniform and equidistant sowing.

[0033] When the device of this embodiment is in use, the seeder is first moved to the sowing field, and then corn seeds and fertilizers are poured into the seed trough 8 and the fertilizer trough 9 respectively, and then the push handle 33 is pushed to move the entire seeder. When the moving wheel 4 on the seeder rolls, the rotation of the wheel shaft 3 will drive the main shaft 24 to rotate through the belt transmission, so that the active friction wheel 27 rotates, and the driven friction wheel 21 is driven to rotate by the friction transmission. The turntable and the connecting rod 22 coaxially arranged with the driven friction wheel 21 form a crank connecting rod mechanism to drive the slide plate 11 to slide back and forth in the slide groove 10. During the reciprocating sliding process of the slide plate 11, the seed hole 14 on the slide plate 11 will be in the feeding hole The seed hole 14 is moved back and forth between the feeding hole 12 and the second feeding trough 132, and the quantitative sowing of seeds is realized by the back and forth transportation of the seed hole 14, and the fertilizer hole 15 moves back and forth between the feeding hole 12 and the first feeding trough 131, and quantitative fertilization is carried out to avoid fertilizer waste. After that, the quantitative seeds and quantitative fertilizers are scattered in the soil under the action of the double-layer sowing tube 16 and the annular guide plate 17, and the fertilizer is distributed around the seeds, which effectively avoids the occurrence of seed burning and seedling burning. Since the feeding and sowing of the seeder is related to the travel of the moving wheel 4, no matter how fast the seeder moves, it can automatically sow at equal intervals, thereby improving the sowing efficiency and ensuring the uniformity of sowing.

[0034] When the sowing spacing needs to be changed for different varieties of corn seeds, it is only necessary to screw the positioning nuts 28 on both sides of the active friction wheel 27 to adjust the position of the active friction wheel 27 and change the transmission ratio between the active friction wheel 27 and the driven friction wheel 21, thereby changing the sowing spacing. The entire adjustment process is simple and quick, which increases the applicability of the seeder.

[0035] Embodiment 2

[0036] Reference Figure 4-5 On the basis of the first embodiment, an adjustment plate 29 is slidably connected to the side of the slide 10 close to the push handle 33, and a plurality of adjustment rods 30 are fixedly connected to the side of the adjustment plate 29 close to the slide plate 11. The end of each adjustment rod 30 away from the adjustment plate 29 passes through the slide plate 11 and extends into a plurality of seed holes 14 respectively. The end of the slide plate 11 close to the adjustment plate 29 is rotatably connected to a threaded shaft 31, and the threaded shaft 31 is threadedly connected to the adjustment plate 29. The threaded shaft 31 is fixedly connected to the crank handle 32 at one end of the threaded shaft 31 located outside the slide 10.

[0037] When the device of this embodiment is in use, the shaking handle 32 can be turned to drive the threaded shaft 31 to rotate, and the thread is used to control the sliding of the adjusting plate 29 to change the distance between the adjusting plate 29 and the slide plate 11, control the extension distance of the adjusting rod 30 in the seed hole 14, and change the seed holding space in the seed hole 14. In this way, the number of corn seeds dropped during each sowing is adjusted, so that the seeder can select the appropriate sowing number according to the corn seed variety and soil conditions. By increasing the adjustable sowing function of the seeder, the application range of the seeder is further improved. Compared with the comparative document, the seeder does not need a motor to provide power, which reduces energy consumption and is more economical and environmentally friendly.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
