Intelligent automatic root tuber crop harvester

Abstract

The invention discloses an intelligent automatic root tuber crop harvester. A conveying separation mechanism separates broken soil and harvested products conveyed by a broken soil feeding device and conveys root tuber crops to a box car or spreads the root tuber crops in strips on the ground; a vibrating compaction break barrow and an electromagnetic vibration excavating machine are arranged in front of the broken soil feeding device, and the vibrating compaction break barrow is connected with a suspension frame device through a connecting rod and is positioned at the front end of the harvester; and the shoveling part and the tail of a digging shovel of the electromagnetic vibration excavating machine are connected with a middle connector, the middle connector is connected with the suspension frame device through a cam shaft, an electromagnetic chuck is connected with the suspension frame device, and a spherical head part at the lower end of a ball head adjusting screw is matched with the inner spherical surface of the electromagnetic chuck. The intelligent automatic root tuber crop harvester can automatically adjust the working parameters of each working part according to soil types, soil specific resistance, soil humidity and harvesting requirements of different crops so as to satisfy the requirement of harvesting the root tuber crops. The intelligent automatic root tuber crop harvester is particularly applicable to heavy soil.

Description

technical field [0001] The invention relates to an agricultural harvesting machine, in particular to an intelligent and automatic root and tuber crop harvesting machine for planting in heavy clay soil. Background technique [0002] At present, there are many types of harvesting machinery for root crops (such as sweet potatoes, garlic, taro, potatoes, peanuts, etc.), including harvesters for segmental harvesting, namely excavators, and large combine harvesters. The structure of the excavator suitable for segmental harvesting is relatively simple, the cost is relatively low, and the supporting power is mostly small and medium-sized tractors, which are more suitable for the current rural economic conditions and productivity development level. In terms of working parts configuration, excavating shovels and separate lifting chains are used. Structural combination, collecting or laying (pile) on the ground, and then picking up manually or mechanically. Existing combined harvestin...

AI Technical Summary

Problems solved by technology

[0004] 1) The driving power of the working parts such as conveying and separation comes from the tractor, which requires a specially designed variable speed transmission system to transmit power. The mechanical transmission chain is long, the structure is complex, the efficiency is low, the noise is large, and the energy saving and environmental protection performance is poor

[0005] 2) With mechanical variable speed, the adjustable speed range of the working parts is limited, the adaptability is poor, and it cannot meet the transportation and separation requirements of different soil types and different harvests

[0006] 3) Simply use mechanical vibration, impact, friction and other forced methods to crush the soil in the transportation and separation link, without considering the crushing and separation in the excavation link at the same time. For crops grown in soil, the fruit-soil separation effect is poor, and the harvest damage rate is high

[0007] 4) The research on basic components such as excavation, conveying and separation is limited to the improvement of mechanical structure, and there is no comprehensive application of advanced technologies such as hydraulic drive, microelectronics and automatic control for system integration, resulting in a low technical level of the whole machine and low-end products. Many, low degree of automation, poor adaptability
