This technology discloses that "the green onion harvester, the positioning frame can be connected to the tractor through the connecting frame, when the tractor drives the positioning frame to move in the groove, the two vibrating shovels can be inserted into the onion ridge soil, and at the same time, the vibrating motor drives the strip frame to rotate up and down around the round bar, thereby driving the vibrating shovel to break up all the roots in the onion ridge soil, so that the green onion roots lose support and fall to the ground, which is convenient for users to take directly, and will not cause any damage to the roots of the green onions, which not only guarantees the commercial value of the green onions, but also improves the efficiency of green onion harvesting."

[0030] When an existing green onion harvester is in use, the length of the blade is adjusted by a bar frame and a connecting plate. The bar frame and the connecting plate are limited by bolts inserted into threaded holes. When the blade vibrates the soil on the ground, it is easy to cause soil splashing. When the soil enters the threaded hole, it is easy to cause the threaded hole to be blocked, making it impossible to put the bolt into other threaded holes, thereby causing the distance between the bar frame and the connecting plate to be unable to be adjusted, reducing the adjustment effect of the device on the blade length. Combined with actual use, this problem is obviously a real problem that exists and is difficult to solve.

The sealing cover 5 is used to seal the second threaded holes on the adjusting plate 4 and the first threaded holes on the connecting plate 2, thereby preventing soil from entering the first threaded holes and the second threaded holes. The baffle 15, the inclined plate 17 and the rubber sleeve 16 are used to block the soil to prevent soil from entering the connection between the connecting plate 2 and the vibration device body 1 and causing blockage, thereby affecting the vibration effect of the blade body 14. Therefore, the device is convenient for sealing the first threaded hole and the second threaded hole without affecting the length adjustment function of the connecting plate 2 and the adjusting plate 4.This reduces the probability of the first threaded hole and the second threaded rod entering the soil, thereby improving the effect of the device on adjusting the length of the blade body 14.
