Description

Technical Field

[0001] This utility model belongs to the field of agricultural machinery, specifically relating to a self-propelled combined wheat plot experimental combined seeder. Background Technology

[0002] Wheat is one of my country's major food crops, and the research and development of new wheat varieties has played a positive role in improving my country's wheat production. According to my country's seed management regulations, the promotion of a variety requires five procedures: breeding, regional trials, production trials, approval, and application. Regional trials are a mandatory procedure before variety approval. Regional trials are large-scale, multi-site screening trials, especially for validating newly bred varieties (lines), providing a platform for more accurately selecting superior crop varieties and for promoting, demonstrating, and showcasing new varieties.

[0003] The basic requirements for regional trials are: a certain amount of seeds must be evenly sown within a specified plot length, with a certain distance walked between plots before sowing the next plot, and the interval between plots must be accurately controlled. However, existing plot trials mostly use manual sowing, which has the drawbacks of uneven seeding density and depth within each row, is labor-intensive and time-consuming, and affects the accuracy of the trial. Summary of the Invention

[0004] The purpose of this invention is to provide a self-propelled combined wheat plot experimental combined seeder that sows evenly, at consistent depth, and with higher operating efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A self-propelled combined wheat plot experimental combined seeder is characterized by comprising a vehicle base, a seed dispenser, and a seeding mechanism.

[0008] The base of the feeding assembly is also provided with a transmission sprocket and an adjusting sprocket, which are connected to the drive device in a transmission manner.

[0009] Furthermore, the sowing mechanism includes a fixed bracket mounted on the vehicle body base, a hydraulic cylinder with its upper end connected to the fixed bracket, a disc seeder rotatably connected to the lower end of the hydraulic cylinder, an adjusting rod with one end rotatably connected to the disc seeder and the opposite end slidably connected to the vehicle body base, and a connecting pipe mounted on the disc rotator. The upper end of the connecting pipe is connected to the seed delivery pipe via a connecting hose and a clamp, and the lower end of the connecting pipe is connected to the disc seeder via a connecting hose and a clamp.

[0010] Furthermore, the number of seed delivery tubes, the number of compartments, and the number of disc seeders are the same.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0025] Please see Figure 1 The preferred embodiment of this application shows a self-propelled combined wheat plot test combined seeder, which sows evenly and at consistent depth, resulting in higher operating efficiency. The seeder includes a chassis base 11, a seed dispenser 1, and a sowing mechanism.

[0026] The vehicle body base 11 is equipped with multiple sets of ground wheels 6. The base 11 also houses a drive unit 4, a fuel tank 5, a seat, and a soil cover. The drive unit 4 is connected to the ground wheels 6 via a transmission mechanism. The base 11 also has multiple supports, each supporting a feeding assembly base 16, on which a seed container 3 is mounted. In this embodiment, the drive unit 4 is a diesel engine, and three sets of ground wheels are provided.

[0027] The seed distributor 1 includes a feeding port 101, a cup body 102 fixedly connected below the feeding port 101, a cone-shaped dispensing device 104 and a segmented seed storage tray 103 arranged below the cup body 102, the segmented seed storage tray 103 having multiple compartments of the same size arranged circumferentially, in this embodiment having ten compartments; the segmented seed storage tray 103 is fixedly mounted on the feeding assembly base 16, a cylindrical seed conveyor 14 is arranged below the segmented seed storage tray 103, the seed conveyor 14 having ten seed delivery tubes arranged circumferentially, the same number as the number of compartments, and the seed delivery tubes 13 are arranged one-to-one with the compartments; a rotating mechanism 106 is rotatably connected between the segmented seed storage tray 103 and the seed conveyor 14, the rotating mechanism 106 having a sprocket and at least one seed discharge hole 105 evenly arranged circumferentially on the rotating mechanism 106.

[0028] The sowing mechanism includes a fixed bracket 7 mounted on the vehicle base 11, a hydraulic cylinder 8 connected to the fixed bracket 7 at its 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 vehicle base 11 at the opposite end, and a connecting pipe 12 mounted on the disc seeder 9. The upper end of the connecting pipe 12 is connected to the seed delivery pipe 13 via a connecting hose and a clamp, and the lower end of the connecting pipe 12 is connected to the disc seeder 9 via a connecting hose and a clamp. 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.

[0029] The base 16 of the feeding assembly is also equipped with a transmission sprocket 15 and an adjusting sprocket 2. The transmission sprocket 15, the adjusting sprocket 2 and the drive device 4 are connected by chain drive. The transmission sprocket 15 is connected to the rotating mechanism 106 through a gear set structure. The transmission sprocket 15 can use different numbers of teeth as needed to adjust the sowing spacing.

[0030] Working principle: The combined seeder shown in this invention requires three people to operate: one to drive, one to continuously feed seeds into the seed distributor 1, and one to observe the sowing situation. After the seeds are put into the seed distributor 1, they are distributed into the compartments of the segmented seed storage tray 103 after passing through the feeding port 101, the cup body 102, and the cone-shaped distribution device 104. When the combined seeder is moving, the drive 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 discharge hole 105 rotates to the corresponding compartment, it sends the seeds in the compartment to the corresponding seed delivery pipe 13, and then through the connecting pipe 12 to the corresponding disc seeder 9 for sowing in the field. The cycle repeats, and the rotation of the rotating mechanism 106 sequentially delivers the seeds to the corresponding ten disc seeders 9.

[0031] Since the ground wheel 6 and the transmission sprocket 15 are powered by the same drive device 4, the rotation angle of the rotating mechanism 106 and the ground wheel 6 are positively correlated. Changes in driving speed do not affect the equidistant sowing of seeds, ensuring uniform sowing depth, neat seedling emergence, and improving the accuracy of the experiment.

[0032] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above 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.

[0033] The embodiments described above are merely illustrative of several implementations of this utility model, and 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 those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
