Description

Technical Field

[0001] The utility model belongs to the field of agricultural machinery, and in particular relates to a self-propelled combined wheat plot test gearbox combined seeder. Background Art

[0002] Wheat is one of my country's staple grain crops, and the research and development of new wheat varieties has played a positive role in boosting wheat production. According to my country's seed management regulations, the promotion of a variety must go through five stages: selection and breeding, regional trials, production trials, approval, and application. Regional trials are a mandatory step before variety approval. Regional trials are multi-site, large-scale screening tests, particularly for confirmatory testing of newly developed varieties (lines). They provide a platform for more accurate selection of superior crop varieties and for the promotion, demonstration, and display of new varieties.

[0003] The basic requirements of regional trials are that a certain amount of seed must be evenly sown within a specified plot length, with walking a certain distance between plots before sowing the next one. The spacing between plots must be precisely controlled. However, existing plot trials often rely on manual sowing, which has the drawback of uneven seeding and varying depths within each row, which is labor-intensive and time-consuming, affecting the accuracy of the experiment. Summary of the Invention

[0021] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0022] See Figure 1The self-propelled combined wheat plot test gearbox combined seeder shown in a preferred embodiment of the present application has uniform sowing, consistent depth, and higher operating efficiency. The seeder includes a seeder base 11, a seed separation device 1, a sowing mechanism, and an adjustment mechanism.

[0023] The seeder base 11 is equipped with multiple sets of ground wheels, along with a drive unit 4, a fuel tank 5, a seat, and a soil cover. The drive unit 4 is in driving connection with the ground wheels. The seeder base 11 is also equipped with multiple brackets, each of which is equipped with a feed assembly base 16. The feed assembly base 16 is equipped with a seed container 3. In this embodiment, the drive unit 4 is a diesel engine, and there are three sets of ground wheels.

[0024] The seed separation device 1 includes a feeding port 101, a cup body 102 is fixedly connected to the bottom of the feeding port 101, and a vertebral distribution device 104 and a grid seed storage tray 103 are further provided below the cup body 102. The grid seed storage tray 103 is circumferentially provided with a plurality of grids of the same size. In this embodiment, there are ten grids; the grid seed storage tray 103 is fixedly penetrated on the feeding assembly base 16, and a cylindrical seed conveyor 14 is further provided below the grid seed storage tray 103. The seed conveyor 14 is circumferentially provided with seed delivery tubes 13 with the same number as the grids, that is, ten, and the seed delivery tubes 13 are arranged one-to-one in correspondence with the grids; a rotating mechanism 106 is also rotatably connected between the grid seed storage tray 103 and the seed conveyor 14, and a sprocket is provided on the rotating mechanism 106. The rotating mechanism 106 is also circumferentially evenly provided with at least one seed discharge hole 105.

[0025] The sowing mechanism includes a fixed bracket 7 arranged on a seeder base 11, a hydraulic cylinder 8 connected to the fixed bracket 7 at the upper end, a disc seeder 9 rotatably connected to the lower end of the hydraulic cylinder 8, an adjusting rod 10 rotatably connected to the disc seeder 9 at one end and slidably connected to the seeder base 11 at the opposite end, and a connecting pipe 12 arranged on the disc rotator 9. The upper end of the connecting pipe 12 is connected to the seed delivery pipe 13 through a connecting hose and a hoop, and the lower end of the connecting pipe 12 is connected to the disc seeder 9 through a connecting hose and a hoop. The height of the disc seeder 9 can be adjusted by the hydraulic cylinder 8 and the adjusting rod 10, thereby adjusting and fixing the sowing depth.

[0026] The adjusting mechanism includes a gearbox 6 arranged on the seeder base 11 and a transmission sprocket 15 and an adjusting sprocket 2 arranged on the feeding assembly base 16. The input shaft of the gearbox 6 is connected to the driving device 4; the transmission sprocket 15, the adjusting sprocket 2 and the output shaft of the gearbox 6 are connected by a chain transmission, and the transmission sprocket 15 is connected to the rotating mechanism 106 by a gear set; the adjusting mechanism adjusts the sowing spacing by changing the transmission ratio of the driving device 4 and the transmission sprocket 15.

[0027] Working principle: The combined seeder shown in the present invention requires the cooperation of three people: one person drives, one person continuously puts seeds into the seed separation device 1, and one person observes the sowing status; after the seeds are put into the seed separation device 1, they pass through the feeding port 101, the cup body 102 and the vertebral distribution device 104 and are distributed to the grids of the grid seed storage tray 103. When the combined seeder is traveling, the driving device 4 simultaneously drives the transmission sprocket 15 to rotate, and the transmission sprocket 15 further drives the rotating mechanism 106 to rotate. When the seed hole 105 rotates to the corresponding grid, the seeds in the grid are sent to the corresponding seed delivery pipe 13, and then transported to the corresponding disc seeder 9 through the connecting pipe 12 and sown in the field; the cycle is repeated, and the seeds are transported to the corresponding ten disc seeders 9 in turn through the rotation of the rotating mechanism 106. If the sowing spacing needs to be changed, it can also be adjusted and changed through the adjustment mechanism.

[0028] Since the ground wheel and the transmission sprocket 15 are powered by the same driving device 4, the rotation angle of the rotating mechanism 106 is positively correlated with that of the ground wheel. Changes in driving speed do not affect the equidistant sowing of seeds, ensuring uniform sowing depth and neat seedling emergence, thereby improving the accuracy of the test.

[0029] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0030] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
