Three-level separation type cyperus esculentus harvester

Abstract

The invention discloses a three-level separation type cyperus esculentus harvester. The three-level separation type cyperus esculentus harvester is characterized by comprising a rack body, a traction frame, fixed depth wheels, a rotary tillage rake, a soil shoveling plate, a storage box and advancing wheels. A transition plate, a first-level screening device, a second-level screening device and a third-level screening device which are connected in an end-to-end mode and arranged in a front and back mode are arranged on the rack body behind the soil shoveling plate. A draught fan and the storage box are arranged below the tail ends of the three levels of screening devices. The three-level separation type cyperus esculentus harvester has the advantages that the first-level screening device, the second-level screening device and the third-level screening device are arranged, and cyperus esculentus is classified and screened step by step when conveyed from front to back and are completely screened when harvested; waste of resources is avoided, the net output rate of the harvested cyperus esculentus is high, the harvested cyperus esculentus can be directly bagged after being dried without manual secondary separation and secondary operation; besides, when the cyperus esculentus falls into the storage box finally, impurities in the cyperus esculentus are blown out by the draught fan, and the net output rate is further increased.

Description

Technical field: [0001] The invention relates to an agricultural machine for harvesting oily bean, in particular to a three-stage sorting type oily bean harvester. Background technique [0002] Yassa bean is a new type of crop with high quality, high yield and high comprehensive utilization value. It mainly harvests underground nuclear rhizome fruits with well-developed root system and high labor intensity when harvesting. Now there are some oily bean excavators on the market. Although the harvesting efficiency has been improved, the harvested oily beans are mixed with more soil and fine impurities, and the screening effect is not ideal. Manual separation and picking are often required. More manpower and material resources are invested, time-consuming and labor-intensive, and the labor intensity is high; in addition, more oily beans are mixed in the discharged grass, which reduces the harvest and affects income. Invention content: [0003] The object of the present invent...
