Description

Technical Field

[0001] The utility model belongs to the technical field of seed drills, and in particular relates to a material leveling structure for seed drills. Background Art

[0002] A seeder is a planting machine that sows crop seeds. Seeders used for a certain type or crop are often named after the crop type, such as grain drills, corn hole seeders, cotton seeders, forage spreaders, etc. There are many types and functions of seeders. Depending on the sowing method, seeders can be divided into spreaders, drills, and spot seeders. Depending on the sowing method, seeders can be divided into spreaders, drills, and spot seeders. The use of seeders can greatly improve the efficiency and quality of sowing, reduce the waste of manpower and material resources, and is one of the important machines that cannot be ignored in modern agricultural production. At the same time, with the advancement of science and technology and the continuous development of agricultural production, the types and functions of seeders are also constantly updated and improved, providing more efficient, accurate and intelligent services for agricultural production.

[0003] When the existing seeder is sowing, the seeds to be sown in the seed box are placed into the furrow opened by the furrow opener through relevant equipment for sowing. However, when sowing, the seeds are easily scattered unevenly when they fall into the furrow, and the seeds may be stacked together, which is not conducive to the growth of the seeds; in addition, since the growth environment of seeds in different regions is different, the sowing distance also needs to be adjusted, but the sowing spacing of the existing seeder is fixed in advance. Each time the spacing is adjusted, it is necessary to stop working and then manually change the installation position of the furrow opener for adjustment. This operation is cumbersome and inconvenient when using. Utility Model Content

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] A material leveling structure for a seed drill, such as Figure 1-Figure 5As shown, the seeder includes a body 1, a seed box 2 is installed on the body 1, a mounting platform 3 is provided below the seed box 2, a plurality of slides 4 are provided on the mounting platform 3, a mounting block 5 is slidably connected in the slide 4, the mounting block 5 can slide back and forth in the slide 4 by the extension and contraction of the first electric control cylinder 6 installed on the mounting platform 3, a furrow opener 22 is installed at the bottom of the mounting block 5, the bottom of the furrow opener 22 is triangular in shape, a mounting plate 7 is also provided on the front side wall of the mounting block 5, a connecting hose 8 is provided on the mounting plate 7, the top of the connecting hose 8 is connected to the seed box 2, and the bottom of the connecting hose 8 is detachably connected to a sowing mechanism 9. The seeder moves slowly in the sowing area during operation, and furrows are opened by the furrow opener 22, and the furrow opener 22 is triangular in shape, so that when the furrow opener 22 cuts the soil, its acute angle part can reduce the contact area with the soil, thereby reducing the furrowing resistance, making the seeder smoother during operation, and forming a seed furrow with a neat furrow shape and consistent depth, which is conducive to the uniform distribution and growth of seeds. After the furrow opener 22 opens a deep furrow, the seeds in the seed box 2 reach the sowing mechanism 9 through the connecting hose 8 for uniform sowing. The seed box 2 is provided with a plurality of tapered openings 20, the bottom of which is connected to the connecting hose 8, and the tapered opening 20 is also provided with an electric control valve 21. The tapered opening 20 is provided to facilitate the seeds inside to enter the connecting hose 8 well, and the electric control valve 21 can adjust the opening of the tapered opening 20 according to the sowing demand, thereby controlling the amount of seed falling. The first electric control cylinder 6 provided on the mounting platform 3 can be extended and retracted under the control of the corresponding controller on the sowing machine, and each first electric control cylinder 6 is independently controlled, so that the mounting block 5 can be driven to slide back and forth in the chute 4 to adjust the position of the furrow opener 22, thereby making adaptive adjustments according to the sowing spacing. Since the sowing mechanism 9 is connected to the mounting block 5 through the mounting plate 7, when the furrow opener 22 moves, the position of sowing will be adjusted accordingly, so that the seeds can accurately fall into the corresponding furrow, thereby facilitating the adjustment of the sowing distance.

[0026] like Figure 2-Figure 4As shown, the sowing mechanism 9 includes a mounting tube 10, a truncated cone-shaped branch tube 11 is installed at the bottom of the mounting tube 10, the small end of the truncated cone-shaped branch tube 11 is connected to the mounting tube 10, a mounting groove 12 is provided on the inner wall of the mounting tube 10, a partition plate 13 is provided in the mounting groove 12, a plurality of leakage holes 14 are provided on the partition plate 13, a plurality of first telescopic springs 15 are provided on the outer wall of the partition plate 13, the first telescopic springs 15 are connected to the inner wall of the mounting groove 12, a plurality of second telescopic springs 16 are provided at the inner top of the mounting tube 10, the second telescopic spring 16 is connected to the partition plate 13, a second electrically-controlled cylinder 17 is installed at the inner bottom of the mounting tube 10, the output end of the second electrically-controlled cylinder 17 is connected to the partition plate 13 through a third telescopic spring 18, a plurality of independent channels 19 are provided in the truncated cone-shaped branch tube 11, and the caliber of the channel 19 gradually increases from top to bottom. The seeds fall onto the partition plate 13, and through the back and forth movement of the second electronically controlled cylinder 17, in cooperation with the first telescopic spring 15, the second telescopic spring 16 and the third telescopic spring 18, the partition plate 13 keeps vibrating, so that the seeds can evenly fall into the truncated cone-shaped distribution tube 11 below through the leakage hole 14, and a channel 19 is provided in the truncated cone-shaped distribution tube 11. In this way, the seeds can be evenly distributed in the opened grooves through the guidance of the channel 19, and the accumulation of seeds in the grooves is avoided. The caliber of the channel 19 gradually increases from top to bottom, which can avoid the blockage of seeds in the channel 19.

[0027] When in use, first control the extension and retraction of each first electrically-controlled cylinder 6 according to the required sowing spacing, drive the mounting block 5 to slide back and forth in the slide groove 4, and adjust the position of the furrow opener 22 and the sowing mechanism 9; after the sowing spacing is adjusted, adjust the opening of the electrically-controlled valve 21, drive the seeder to move slowly, and use the provided furrow opener 22 to open the furrow. After the furrow opener 22 opens a deep furrow, the seeds in the seed box 2 reach the sowing mechanism 9 through the connecting hose 8, are distributed through the partition plate 13, and finally fall into the deep furrow through the channel 19 provided in the truncated cone distribution tube 11, so as to ensure uniform sowing.

The technicians in this technical field may make various modifications or additions to the specific embodiments described or replace them in a similar manner. As long as they do not deviate from the concept of the utility model or exceed the scope defined in the claims, they should all fall within the protection scope of the present utility model.
