The soil guide screen assembly is connected by the two basket bolts 10 through the rotating shaft, and the effect of freely adjusting the angle of the soil guide screen assembly can be achieved, so that the ideal soil guide effect is achieved, and root crops in soil shake onto the soil surface along with the soil guide screen, so that the harvesting effect is achieved.
The beneficial effects of the scheme are that：
The utility model has at least the following advantages:
1. in order to ensure convenient refitting, short refitting period and adaptability to tractor suspension with different requirements, the three-point suspension in the traditional mode is adopted, and the three-point suspension has the advantages of strong adaptability, convenience in disassembly and assembly, high interchangeability and the like.
2. In order to lighten the advancing resistance of the operation and improve the operation efficiency, the purposes of crushing and deep scarification are achieved at the same time, the shovel frame is used for shaking up and down to enter the soil with high frequency and low amplitude, so that the resistance born by the shovel frame is reduced in the process of entering the soil for harvesting, and the advancing resistance of the operation can be lightened because the shovel frame is shaking up and down with high frequency and low amplitude and the feeding amount of entering the soil each time is small. Meanwhile, the purpose of crushing and deep scarification can be achieved due to short shaking.
3. In order to ensure that crops with different soil properties and different roots can be successfully harvested, the soil guide screen assembly can be used for adjusting the angle. When the soil is wet and sticky, the included angle between the soil guiding screen and the soil shoveling frame is large; when the soil quality is dry and the sand is scattered, the included angle between the soil guiding screen and the soil shoveling frame can be reduced, the soil guiding effect can be better achieved, the rhizome crops can shake continuously along with the soil shoveling frame and continuously go to the soil surface through the soil guiding screen, and therefore the effect of harvesting the rhizome crops is achieved.
4. By adopting the technical scheme, the utility model has the advantages of simple structure, convenient manufacture and modification, small working running resistance and high working efficiency, can break the soil structure, crush and harden the soil, plays a role in soil fattening and can harvest different rhizome crops.
