Description

Harvesting crane and harvesting method using the same}

The present invention relates to a harvesting crane and a harvesting method, and to a harvesting crane for harvesting a harvest, such as a palm (palm) and a harvesting method using the same.

The harvest that can be harvested by the harvesting crane of the present invention is open to a place much higher than the height of the worker, for example, a farm, and may be anything else. Palm is a type of palm, and it is grown a lot to extract palm oil. There are many farms located in Africa, Southeast Asia, and Malaysia. Early on, the farm farms are being cultivated in anticipation of the availability of the farms. The entire farm is being developed.

Palm oil extracted from palm is recognized as an important raw material because of its high utilization in food and industrial purposes such as cooking oil, soap, confectionery, medicine, cosmetics, and glycerin. In Europe, palm oil is also used as a vehicle fuel to expand the use of biofuels. Biofuels, including palm oil, are clean energy and are increasingly used internationally.

Since the palm fruit opens at the top of the palm tree, a specially designed palm harvesting sickle was used to manually harvest the palm fruit located far higher than the worker's height. Palm harvesting sickle is a type of sickle attached to the end of a long pole that is several times the height of a person, and the worker can harvest the palm fruit by swinging the palm harvesting sickle and cutting off the top of the palm fruit. However, since skilled skills are required to manipulate the farm sickle, labor costs associated with securing a competent worker are required, resulting in a poor economic efficiency of farm harvesting. In addition, there is a risk that a human accident may be caused by a worker who is abrasion, or the palm falling to the ground by wrong operation of the farm harvest sickle.

On the other hand, palms that grow mainly in the tropics grow in a very short time after harvesting once, and then the next harvest time. If you do not shorten the time to harvest the palms, the palm fruits will not be harvested and will be discarded and productivity will decrease. do. To shorten the time required for farm harvesting, the number of people and working hours must be increased for manual work, and the utilization and reliability of the harvesting device must be ensured with mechanized harvesting devices.

Economic deterioration or human life concern, which is pointed out as a problem of the conventional harvesting method using the farm harvest sickle, occurs because the harvest is located at a much higher position than the worker, and can be improved by reducing the distance between the harvest and the worker. In other words, if the worker can be close to the harvest can harvest the harvest easily even if the worker is less skilled.

Therefore, the worker can be safely lifted from the ground to the harvest height, the harvest can be easily harvested by raising the worker to the harvest height, and the harvest harvested from the high place can be sent down to the ground without damage, It is an object of the present invention to provide a harvesting crane capable of loading and transporting a large amount of harvest. Thus, it is possible to shorten the farm harvesting time, to increase the work efficiency and operation rate of the device, and to provide a harvesting crane and a harvesting method using the same, which can secure safety and reliability.
