Description

Self-propelled crop harvesting apparatus {Driving type crop harvesting apparatus}

The present invention relates to a self-propelled crop harvester having a driving capability for harvesting crops such as spinach, ginger, and potatoes.

In detail, it relates to a self-propelled crop harvester made to be able to harvest more easily by cutting the root or stem part according to the type of crop.

In general, spinach, which is a soft leafy vegetable, can be easily damaged due to its fragility when harvesting, and due to this, most farmers mobilize workers to harvest spinach manually to prevent deterioration of marketability due to spinach damage.

However, since spinach growers harvest spinach by manpower, there is a problem in that they have to spend excessive labor costs, while workers for harvesting spinach due to the decrease in the population of farms are also difficult to obtain, depending on the circumstances and causes of excessive labor costs. This will lead to an increase in production cost and unstable supply of spinach.

In order to prevent such side effects and problems, a technology for a spinach harvester for automatically harvesting spinach has been developed and started to be provided.

The prior art related to the spinach harvesting period includes (KR) a spinach harvester in Publication No. 10-2005-0072890, (KR) a spinach harvester in Publication No. 10-2013-0053557, and (KR) Utility Model Publication No. 20-2008-0001291. Various technologies, such as a hoin spinach harvesting device, are provided as patent documents.

The spinach harvester provided in the related art includes a spinach harvesting body including a spinach root cutting part provided with a spinach root cutting blade for cutting the spinach root at the front end and a cut spinach moving part for moving to collect the spinach cut at the spinach root cutting part. , Consisting of a driving vehicle body including a driving power device for driving and a driving wheel for driving connected to the driving power device.

Such a conventional spinach harvester cuts the roots of spinach with a spinach root cutting blade, moves the cut spinach with a spinach moving part, and collects the cut spinach in a collection box to harvest spinach.

In general, spinach root cutting blades are formed to be long left and right to cut a large amount of spinach when viewed from the front, and when the environment of the field where the spinach is grown is different from the height of the left and right ground and the moving ground is uniform There are cases such as not being able to do so.

In this case, spinach cut with long spinach root cutting blades on the left and right is often not done with the root of the spinach being cut to an appropriate length, the spinach body is cut, or the root is cut too short, etc. A phenomenon that causes damage to the product occurs.

In order to prevent such damage, the operator must often stop the operation and adjust the position of the spinach root cutting blade during the driving harvest, which causes problems such as a decrease in the harvesting capacity of spinach.
