Background

The phenomenon that beet slips from between the digging cutter often can take place for current beet harvester in digging the beet process to when meetting the comparatively firm beet of root system, digging cutter root originally can't dig the beet from soil, lead to partial beet to be detained in the field, cause certain economic loss.

Disclosure of Invention

The invention provides a vibrating excavation structure for a beet harvester, which aims to solve the problems that beet frequently slips from between excavating knives in the beet excavating process of the existing beet harvester and the roots of the excavating knives cannot dig up the beet from soil when the beet with a firmer root system is encountered.

The technical scheme adopted by the invention for solving the problems is as follows: the invention comprises an eccentric wheel component, a share handle component and two root digging mechanisms, wherein the eccentric wheel component is connected with a power output shaft of traction equipment, the eccentric wheel component is connected with the upper end of the share handle component, and the two root digging mechanisms are arranged at the lower end of the share handle component side by side.

Furthermore, the eccentric wheel assembly comprises a cam and a connecting arm, a cam shaft of the cam is eccentrically arranged and is connected with a power output shaft of the traction equipment, the cam is connected with one end of the connecting arm, and the other end of the connecting arm is connected with the upper end of the share handle assembly.

Furthermore, the share handle assembly comprises a share handle, a share handle rotating shaft and two driving handles, the upper end of the share handle is connected with the lower end of the connecting arm, the lower end of the share handle is connected with the share handle rotating shaft, the two driving handles are arranged side by side, the upper end of each driving handle is connected with the share handle rotating shaft, and the lower end of each driving handle is connected with one root digging mechanism.

Furthermore, each root digging mechanism comprises a root collecting column and a digging sliding knife, the root collecting column is connected with the lower end of the driving shaft, and the digging sliding knife is arranged on the bottom edge of the root collecting column.

Further, the root block collection column is formed by sequentially connecting the front root block collection column and the rear root block collection column end to end.

The invention has the beneficial effects that: according to the invention, in the excavation process, firstly, soil on the beet tuberous roots is loosened, the beet tuberous root digger is fed into the machine tool by matching the excavation sliding cutter and the tuberous root collecting column, so that the beet tuberous root excavation operation is completed, and the soil is loosened before excavation, so that the beet tuberous roots can be easily excavated from the soil, the phenomenon of missing excavation caused by over tight connection between the beet tuberous roots and the soil is avoided, the harvest rate of the beet tuberous roots is improved, and the economic loss is reduced.
