Excavating and screening device for rhizoma corydalis

Abstract

The invention discloses an excavating and screening device for rhizoma corydalis. The excavating and screening device comprises a main frame, a tunneling shovel, a soil pulverizing roller, a lifting mechanism, a cylinder screen, and a collecting box, wherein a first support and a second support are arranged on the main frame, a cylinder screen shaft is arranged inside the cylinder screen, and the first support and the second support are used for supporting the cylinder screen shaft; the tunneling shovel is arranged at the bottom of the lifting mechanism, the top of the lifting mechanism corresponds to an inlet in the front of the cylinder screen, the soil pulverizing roller is arranged above the tunneling shovel, and the soil pulverizing roller is fixed on the main frame through a third support; the collecting box is arranged on the main frame and is communicated with the outlet of the rear part of the cylinder screen. The excavating and screening device for rhizoma corydalis is capable of improving efficiency of separation of fruits of rhizoma corydalis and soil and has no damage to the fruits of rhizoma corydalis and soil; meanwhile, the manufacturing cost of the device is low, and high net fruit rate and backfilling of the soil are thus achieved.

Description

technical field [0001] The invention relates to the technical field of crop collection, in particular to a Yuanhu digging and screening device. Background technique [0002] Yuanhu, also known as Yanhusuo and Xuanhu, is a flat-spherical, 0.5-2.5cm in diameter, yellow rhizome-like Chinese herbal medicine. Yuanhu is cultivated in many parts of the country, and the main production areas are Jinhua Pan'an County, Dongyang City, Qinba Mountains and other places in Zhejiang Province. From May to June every year, after the plants of Yuanhu are completely withered, it is time to harvest. Farmers use manual digging, which is inefficient. [0003] At present, the existing Yuanhu harvester is not suitable for harvesting Yuanhu in mountainous and hilly areas because the model is too large. There is also an improved version of the potato harvester, which cannot separate the soil from the fruit well. Fruit rate is low. [0004] Therefore, there is an urgent need for a small-sized devic...
