Small crawler type tuber combine harvester

Abstract

The invention discloses a small crawler type tuber combine harvester which comprises a power walking mechanism, wherein an excavation mechanism and a conveying and cleaning mechanism are arranged on the power walking mechanism; the excavation mechanism is located in front of the conveying and cleaning mechanism and fixedly connected to the conveying and cleaning mechanism; the power walking mechanism comprises a crawler type walking chassis on which a gearbox is arranged; the gearbox is connected with a belt pulley through a belt; the belt is connected with a driving rotation shaft through a driving wheel; the conveying and cleaning mechanism comprises a conveying device, a support wheel and an intermediate shaft; the support wheel and the intermediate shaft are used for bearing the conveying device; and the conveying device comprises a plurality of conveying chains and is connected with the crawler type walking chassis through the driving rotation shaft. The small crawler type tuber combine harvester has the beneficial effects that by using the crawler type walking chassis, stepless speed change walking is realized, the center of gravity of the whole harvester is low, the safety coefficient is high and the miniaturization and compaction of the harvester are conveniently realized; and by using a sing-step conveying chain structure, the combination process of excavation, separation, cleaning and box collection is realized.

Description

technical field [0001] The invention belongs to the field of agricultural machinery and equipment, and relates to a harvesting machine for potato crops such as potatoes and sweet potatoes, in particular to a small crawler-type potato combine harvester. Background technique [0002] At present, the common potato harvesting machines at home and abroad mainly include excavators and combine harvesters. For the potato excavator, excavation and collection are segmented operations, requiring manual secondary picking, with a low degree of mechanization and high labor intensity. The combine harvester can realize the functions of excavation, separation, conveying, and container collection with high operating efficiency, but it is a large and medium-sized machine tool with a large mechanical volume, heavy body weight, high use cost, and large supporting power. It is suitable for large plots and centralized planting area. However, in my country, the arable land area is in short supply...

AI Technical Summary

Problems solved by technology

However, the conveying mechanism adopted in this patent includes a two-stage soil and potato separation and conveying device, which is still relatively large in size; moreover, it adopts a tractor traction power supply mode, which is even more unfavorable for use in small plots in hilly and mountainous areas.
