Self-propelled double row carrot combine harvester

Abstract

Disclosed is a self-propelled double row carrot combine harvester. The self-propelled double row carrot combine harvester is composed of a lifting grain guiding device, an excavating device, a slant clamping conveying device, a soil removing device, an alignment vine cutting device, a horizontal belt conveying device, a lifting fruit collection device, a crawler chassis, a power transmission system, a hydraulic system and the like, wherein the excavating device, the lifting grain guiding device, a depth wheel, the slant clamping conveying device, the soil removing device and the alignment vine cutting device are installed on a front machine frame, the front machine frame is installed at the front end of one side of a power output shaft of the crawler chassis, the horizontal belt conveying device and the lifting fruit collection device are installed on a rear machine frame, and the rear machine frame is fixed on the crawler chassis at the rear end of the front machine frame. The self-propelled double row carrot combine harvester can simultaneously complete excavating, clamping conveying, stem and leaf separation, oil removing and harvesting operation of two rows of carrots, facilitates improvement of the mechanization level of the carrot harvesting operation, and improves operation efficiency.

Description

technical field [0001] The invention belongs to the field of agricultural machinery and equipment, in particular to a carrot combine harvester, in particular to a self-propelled double-row carrot combine harvester. Background technique [0002] my country is the country with the largest carrot planting area in the world, and its total output accounts for about 40% of the world's total carrot planting area. However, most of the carrot planting areas in my country are mainly harvested manually, which is labor-intensive and low-efficiency, which seriously affects the timely harvest of carrots and limits the production scale of my country's carrot industry. [0003] At present, the research and development of carrot combine harvesters in developed countries has formed a system, which can be roughly divided into two types: traction type and self-propelled type. Countries in Europe and the United States mainly use large side-mounted traction combine harvesters, which not only hav...

Problems solved by technology

However, there are the following problems: (1) foreign carrot harvesters are expensive, and the cost of after-sales maintenance is high, which exceeds the purchasing power of farmers; (2) the difference in agronomy at home and abroad, foreign carrot harvesters do not meet the planting requirements of domestic varieties

[0005] However, the carrot harvester described in this invention patent application is simple in structure, and still has some shortcomings: (1) the reciprocating soil discharge mechanism removes the soil through vibration, which is easy to damage the carrots, and it is difficult to ensure that the soil on the carrots is removed; 2) The structure of the clamping and conveying mechanism is simple, causing the carrots to fall easily during the conveying process; (3) Harvesting in a single row, the work efficiency is low, and the soil compaction is serious at the same time
