Description

The present invention relates to a crop harvesting assistance device and a harvester for assisting the harvesting of crops existing in the field.

In recent years, the labor force of young people has decreased in Japan as the population ages, and it is predicted that this tendency will become stronger in the future. The agricultural working population is steadily declining, and the aging of the population is progressing rapidly. While securing and training new farmers is required to secure a stable supply of food, there is an urgent need to further mechanize the agricultural work itself and promote labor saving.

For example, unlike house tomatoes for raw consumption, processed tomatoes to be made into juice or ketchup can be grown on a crawl without pillars and can be cultivated in an extremely labor-saving manner. However, when it comes to harvesting crops that crawl on the ground in this way, the work burden is enormous because of the heavy human labor and manual labor involved.

Therefore, it is desired to develop a technique for mechanizing the harvesting work of agricultural products that crawl on the open field.

As prior art documents related to the above problem, the applicant has grasped the following Patent Documents 1 to 3.
