Description

Technical Field

[0001] The invention relates to the field of red date picking, in particular to a portable handheld red date picking device. Background Art

[0002] With the advancement of modern science and technology and the development of society, the mechanization of picking red dates has developed to a certain extent. However, in hilly areas or places where large machines cannot reach, manual picking is still required. This is because the manual method of picking red dates has become increasingly backward and it is difficult to meet the requirements of harvesting efficiency and quality. Therefore, in response to this problem, a portable handheld red date picking device is developed to cope with the situation where manpower is needed for picking.

[0003] Existing red date picking machines include small handheld picking devices and large red date harvesters. Although small handheld picking devices are easy to carry and easy to operate, most of them use the principle of excitation for picking. During field operation, the excitation force will be directly transmitted to the human body through the handheld part, causing physical discomfort. The present invention improves the principle of this problem and adopts a patting method for harvesting; while improving the comfort of the human body during the harvesting process, the efficiency of harvesting is guaranteed by rapid up and down reciprocating patting. For large red date harvesters, although the automated picking process can be realized, in mountainous and hilly areas, the harvesting cannot be carried out because the equipment is too large. At this time, a handheld picking device is still needed to help with the harvesting. Therefore, it is of great practical significance and broad market prospects to design a picking device that can adapt to a variety of harvesting environments to ensure the picking efficiency and improve the operating experience of date farmers.
