[0018] 2. The garlic sprout harvester with adjustable harvesting height is provided with a set of synchronous wheels I at one end of the conveying roller II. The synchronous wheel I will rotate along with the conveying roller II and drive the synchronous wheel II to rotate through the synchronous belt, so that the cleaning roller on one side of the synchronous wheel II will rotate synchronously. When the rotating cleaning roller contacts the conveying belt, the garlic sprouts adhered to the conveying belt will be cleaned off and fall onto the inclined guide plate.

[0019] 3. The garlic sprout harvester with adjustable harvesting height needs to install seedling pushing plates on both sides to gather the garlic sprouts to the cutting knife when harvesting garlic sprouts. In order to adapt to garlic sprout planting areas of different widths, the angle of the seedling pushing plate needs to be adjusted by pulling the handle II to move upward. When the handle II moves, the tension spring can be pulled to extend through the connecting block movably connected at the bottom. When the clamping rods around the handle II are disengaged from the cleaning roller, the handle II can be rotated to drive the connecting shaft and the seedling pushing plate to rotate, so that the angle of the seedling pushing plate changes. In this way, the angle of the seedling pushing plate of the garlic sprout harvester can be adjusted through the above operations to adapt to garlic sprout harvesting sites of different widths.

[0038] The switching mechanism 23 includes a handle I231 slidably connected to the outer side of the threaded rod 13, a gear I232 is installed at the bottom of the handle I231, a protrusion 233 is fixed on the inner side of the gear I232, an annular groove I234 and an annular groove II236 are opened inside the threaded rod 13, and the annular groove I234 and the annular groove II236 are both slidably connected to the protrusion 233, a vertical groove 235 is arranged between the annular groove I234 and the annular groove II236, the vertical groove 235 is opened on the outer side of the threaded rod 13, a gear II237 is arranged on one side of the gear I232, the gear II237 is installed on the connecting rod 18, and the gear I232 can mesh with the gear II237.

[0039] In a specific implementation, when adjusting the height of the movable cutter 6 and the static cutter 8, the handle 1231 in the switching mechanism 23 is pulled upward, and the handle 1231 drives the internal protrusion 233 to disengage from the annular groove 1234 and enter the vertical groove 235. At this time, the protrusion 233 can be engaged with the threaded rod 13, and the handle 1231 can be turned to drive the threaded rod 13 to rotate.

[0043] In specific implementation, the garlic sprout harvester with adjustable harvesting height needs to install seedling-pushing plates 38 on both sides in order to gather the garlic sprouts to the cutting knife when harvesting garlic sprouts. In order to adapt to garlic sprout planting areas of different widths, the angle of the seedling-pushing plates 38 needs to be adjusted, and the handle II34 is pulled up to move upward. When the handle II34 moves, the tension spring 36 can be pulled by the connecting block 35 movably connected at the bottom to extend. When the clamping rods 39 around the handle II34 are disengaged from the clamping groove, the handle II34 can be rotated to drive the connecting block 35 to move upward.
