It is used for a certain type of crop and is often named after the crop type, such as grain drill, corn hole seeder, cotton seeder, forage spreader, etc. The object of sowing by the seeder is crop seeds or pelletized coated seeds. According to the sowing method, it can be divided into three categories: vacuum seed seeder spreader, drill seeder and hole seeder.

[0003] The existing announcement number CN208210650U discloses an agricultural seeder that is easy to adjust the spacing. Although a soil covering mechanism is provided, the seed burying plate of the soil covering mechanism closes the soil gathered during the hole-pointing process to play the role of burying the seeds and covering the soil. The seeder provided in the embodiment of the utility model can realize the processes of hole-forming, sowing and burying seeds during the walking process. At the same time, the sowing spacing can be controlled according to needs, and seeds of different particle sizes can be sown according to user needs. It has strong versatility and can effectively reduce the cost.

[0004] Based on the above, the inventors found the following problems: However, the sowing spacing is adjusted by adjusting the number of hole formers installed on the roller, which requires the hole formers to be fixed in advance, and a large force needs to be applied when the hole formers are used. The hole formers need to be installed very firmly, and when the sowing spacing needs to be adjusted, all the hole formers can only be removed and reinstalled, which is very inconvenient.

[0005] Therefore, in view of this, the existing structure and defects are studied and improved, and an agricultural seeder that is easy to adjust the spacing is provided, in order to achieve a more practical purpose. Utility Model Content

[0027] The utility model provides an agricultural seeder which is convenient for adjusting the spacing, comprising a connecting rod 1, wherein two connecting rods 1 are provided, handles 2 are fixed on the tops of the two connecting rods 1, threaded sleeves 7 and threaded rods 17 are rotatably connected to the bottom ends of the two connecting rods 1, a seed box 3 is fixed on one side above the connecting rod 1, a material guide box 4 is penetrated and fixed on the bottom end of the seed box 3, a material guide tube 5 is penetrated and fixed on the bottom end of the material guide box 4, a connecting disk 9 is fixed on the middle part of the outer wall of the threaded rod 17, a guide rail 8 is fixed on one side of the connecting disk 9, a moving block 13 is movably installed on the other side of the connecting disk 9, a limiting plate 12 and a material blocking plate 14 are fixed on the other side of the connecting disk 9, a cover plate 16 is fixed on the material blocking plate 14, and rotating wheels 6 are fixed on the opposite ends of the threaded sleeves 7 and the threaded rods 17.

[0028] Among them, a feed hole 15 is opened on the outer wall of the baffle plate 14, and there are multiple feed holes 15, which are arranged equidistantly around the circumference. Through the set feed holes 15, the seeds in the guide tube 5 can fall into the moving block 13. The moving block 13 is U-shaped, and the seeds can be stored in the moving block 13.

[0029] Among them, there are multiple moving blocks 13, and the multiple moving blocks 13 and the multiple feeding holes 15 are arranged in a one-to-one correspondence. The baffle plate 14 is always rotating at the bottom of the guide tube 5. When each feed hole 15 passes through the guide tube 5 once, a seed will fall into the feed hole 15 and then fall into the inside of the moving block 13.

[0030] Among them, a slide groove 10 is opened through one side of the connecting plate 9, and the slide groove 10 is arranged in an arc shape. A slider 11 is fixed to one side of the moving block 13. The slider 11 is slidably connected to the slide groove 10, and the other end of the slider 11 is slidably connected to the guide rail 8. By rotating the threaded rod 17 inside the threaded sleeve 7, the guide rail 8 is driven to rotate outside the slider 11. Through the limitation of the slide groove 10, the slider 11 drives the moving block 13 to move in the limiting plate 12.

[0031] The length of the moving block 13 is slidably connected to the limiting plate 12 , and the sum of the lengths of the moving block 13 and the limiting plate 12 is greater than the radius of the connecting disk 9 , so that the moving block 13 will not separate from the limiting plate 12 .

[0032] Among them, the vertical cross-section of the material guide box 4 is set in a right-angle trapezoidal shape, the bottom end of the material guide tube 5 is in contact with the outer wall of the baffle plate 14, the projection area of ​​the bottom end of the material guide tube 5 is matched with the projection area of ​​the feed hole 15, and the seeds are poured into the material guide tube 5 through the material guide box 4. The material guide tube 5 is thinner and can arrange the seeds vertically in sequence.

[0033] The specific usage and function of this embodiment are as follows:

[0034] In the utility model, first, the seeds are poured into the seed box 3, and then the seeds are poured into the guide tube 5 through the guide box 4. The guide tube 5 is thin and can arrange the seeds vertically in sequence. When the handle 2 is pushed to drive the connecting disk 9 and the rotating wheel 6 to rotate, the baffle plate 14 is always rotating at the bottom of the guide tube 5. When each feed hole 15 passes through the guide tube 5 once, a seed will fall into the feed hole 15 and then fall into the moving block 13. When the rotating wheel 6 and the connecting disk 9 continue to rotate, the moving block 13 loaded with seeds moves toward the ground, and the seeds inside are poured into the ground. The empty moving block 13 continues to move to the guide tube 5 to collect the seeds inside. When adjusting the spacing of the seeds, the threaded rod 17 is rotated inside the threaded sleeve 7 to drive the guide rail 8 to rotate outside the slider 11. The slider 11 drives the moving block 13 to move in the limiting plate 12 through the limit of the slide groove 10. After the movement is completed, the threaded rod 17 and the threaded sleeve 7 are stopped from rotating. At this time, the spacing between the moving block 13 and the connecting disk 9 changes. The farther the moving block 13 is from the middle of the connecting disk 9, the faster the seeds fall to the ground, and the closer the spacing between the seeds after sowing. Conversely, the closer the moving block 13 is from the middle of the connecting disk 9, the slower the seeds fall to the ground, and the farther the spacing between the seeds after sowing. This changes the time when the seeds fall to the ground, thereby changing the sowing spacing.
