Description

Technical Field

[0001] The invention relates to the field of agricultural machinery, in particular to a pre-cut sugarcane seed metering device. Background Art

[0002] The typical structure of the seeding device is mainly divided into real-time cutting type and pre-cutting type. At present, the real-time cutting type planter is the most widely used model in agriculture. As the region with the largest sugarcane planting area in the country, Guangxi mostly uses rolling-cutting cutting seeding devices for mechanized sugarcane planting. The use of this structure of seeding devices requires manual feeding, which is labor-intensive and requires a large number of people. Sugarcane is mostly curved and not easy to feed into the mechanism. The manual feeding speed is different, resulting in poor seeding uniformity. When cutting seeds in real time, the seedlings are prone to bud damage and bud breakage, affecting the germination rate. Incomplete disinfection affects the quality of seed buds. The pre-cutting type does not require manual labor for seeding, has a high degree of automation, and can improve production efficiency. The seeding object is pre-cut sugarcane seeds, which is suitable for factory processing, but the seeding process is difficult to control, and accurate seeding is currently impossible.

[0040] Working principle and process:

[0041] The pre-cut sugarcane seed meter is a two-stage separation pre-cut sugarcane seed meter, which is divided into three stages during operation.

[0042] Seed filling stage: After the carton filled with sugarcane seeds is opened, the sugarcane seeds flow from the carton into the seed filling box 2. The sugarcane seeds on the left side of the bottom layer first hit the diverter plate 3, and begin to flow along the inclined surface of the diverter plate 3 under the action of gravity, while the sugarcane seeds on the right side directly touch the rear wall of the seed filling box 2 and flow toward the outlet along the arc surface.

[0043] First-stage seeding stage: After the first-stage seeding process is completed, the sugarcane seeds in the seeding box 2 no longer move and are in a stable state. The first-stage motor 8 and the second-stage motor 15 are turned on, the machine starts to work, and the first-stage seeding roller 5 and the second-stage seeding roller 13 start to rotate. When the first-stage seeding roller 5 drives the first-stage paddle 6 to rotate below the first-stage seed supporting bucket 7, the first-stage paddle 6 on the first-stage seeding roller 5 passes through the empty slot of the first-stage seed supporting bucket 7 and hits the sugarcane seeds. The sugarcane seeds move outward and open the seeding baffle 4 until they are discharged. Then the first-stage paddle 6 rotates away from the exit of the seeding box 2, and the space in the first-stage seed supporting bucket 7 is vacated. The sugarcane seeds in the seeding box 2 begin to move downward and are refilled. At the same time, the seeding baffle 4 returns to its position to prevent the newly filled sugarcane seeds from slipping out. Finally, the space in the first-stage seed supporting bucket 7 is filled again, waiting for the next hit of the first-stage paddle 6.

[0044] Secondary seeding stage: After the sugarcane seeds are discharged from the primary paddle 6, they enter the seeding box 9. The falling sugarcane seeds first hit the first layer of the diverter roller 10, and then slide down the outer wall of the roller to the gap by gravity, and are diverted and straightened by the four layers of diverter rollers until they fall into the secondary seeding bucket 12. Under the restriction of the front and rear side plates at the bottom of the seeding box 9, the sugarcane seeds are arranged in a single row on the secondary seeding bucket 12. When the secondary seeding roller 13 rotates to the bottom of the secondary seeding bucket 12, the secondary paddle 14 on the secondary seeding roller 13 passes through the empty slot of the secondary seeding bucket 12, hits the sugarcane seeds and discharges them in sequence, and finally achieves single-root precise seeding.
