Soil screening device for tuber crop harvester

Abstract

The invention relates to the technical field of harvesters, and also discloses a soil screening device for a tuber crop harvester. The soil screening device comprises a fixed frame, wherein a motor isinstalled on the front surface of the fixed frame and located on the front surface of a rotating shaft located at a left side position; two rotating shafts are rotatably connected with and arranged at the inner side of the fixed frame; rotating wheels are welded at the outer sides of two rotating shafts; the outer sides of the two rotating wheels are in transmission connection via a conveying belt; and the conveying belt is a net-shaped belt and is in a loose state. The soil screening device for the tuber crop harvester provided by the invention has the following advantages: a distinguishingroller and a pressure roller are mounted on the conveying belt; when the soil screening device is in use, tuberous crops are longitudinally arranged on the conveying belt by the distinguishing rolleraccording to sizes; and the pressure roller and an outer sleeve are matched to crush large soil blocks or soil wrapped on crops, and crushed soil falls off through meshes of the conveying belt, so thesituations of the influence on normal operation and reduction of working efficiency due to the fact that the soil wrapped on the crops and the large soil blocks are mixed together and are difficult to distinguish are prevented.

Description

technical field [0001] The invention relates to the technical field of harvesters, in particular to a soil screening device for a harvester of stem and tuber crops. Background technique [0002] With the development of science and technology, my country's productivity has taken off, especially in agriculture, which has now achieved semi-mechanization or even full mechanization, such as various seeders, harvesters, etc., which have effectively liberated the labor force and improved work efficiency. efficiency. [0003] When collecting stem crops, the stem crops are first dug out of the soil by a harvester, and then collected manually. Since the fruits of these crops are buried in the ground, the crops dug out in the land with high humidity , may be wrapped in soil, and it is difficult to identify when collecting later, or the excavated crops are covered again by the soil thrown up by the harvester. sub-device. Contents of the invention [0004] In view of the above proble...
