Description

Technical Field

[0001] This invention belongs to the technical field of garlic harvesters, and specifically relates to a garlic harvester. Background Technology

[0002] Garlic combine harvesters are used to harvest garlic. Currently, the general structure of a garlic harvester typically includes a feeding unit, a soil-shoveling unit, a lifting and conveying unit, a stem-cutting unit, a root-cutting unit, and a transmission unit.

[0003] The current structure has the following problems, especially for small hand-held garlic harvesters.

[0004] A shaving unit typically includes several shaving blades and a shaving drive assembly. Since there are different requirements for shaving during operation, the shaving blades need to be adjusted up and down. Currently, the height of the shaving blades is generally adjusted by using shims. This means that the shaving blade disc needs to be removed and the number of shims on the rotating shaft needs to be adjusted to adjust the height of the shaving blades. This adjustment method is inconvenient to operate, the tool operating space is limited, it is not easy to disassemble and assemble, and each blade needs to be adjusted individually, making the whole process time-consuming and laborious.

[0005] The lifting and conveying unit generally includes an upper conveying unit and a lower conveying unit. The stem-cutting unit includes several stem-cutting blades and a stem-cutting rotating shaft. In the existing structure, the upper conveying unit is generally directly connected to the stem-cutting unit through a universal joint, that is, directly connected to the top of the stem-cutting rotating shaft through the universal joint. This structural form has a drawback, which is that it makes it inconvenient to adjust the height of the stem-cutting blades. In the existing technology, the height of the stem-cutting blades is generally adjusted by adding or removing shims. However, since the universal joint is directly connected to the top of the stem-cutting rotating shaft, the universal joint must be removed in order to remove the stem-cutting blades and increase or decrease the number of shims under the stem-cutting blades to complete the height adjustment. Therefore, this method is inconvenient to operate and is time-consuming and labor-intensive.

[0006] Furthermore, existing small hand-held garlic harvesters are generally driven by diesel engines and have corresponding transmission systems. The transmission system is too large, resulting in an excessively wide harvester body. To harvest two rows of garlic, the machine must work across three rows to harvest two rows of garlic. This method requires harvesting in circles, which is cumbersome and results in low harvesting efficiency. Summary of the Invention

[0007] This invention provides a garlic harvester that can solve the problems pointed out in the background art.

The lower end of the stem-cutting rotating shaft is connected to the lower-level conveyor chain of the lower-level conveying unit. The main gear set is connected to a bevel gear transmission group via a secondary transmission chain. The bevel gear transmission group is connected to the shaving drive assembly and the feeding transmission system of the feeding unit via a first universal joint and a second universal joint, respectively.
