AIR BLAST SOFT FRUIT HARVESTING DEVICE

摘要

The invention relates to the air blast soft fruit harvesting device comprising an air flow director (1), pulsator (2), distancing channel (3), segmented extension (4) and blower fan (5) assembly. The distancing channel (3) is connected with the segmented extension (4) on the top side and with the pulsator (2) on the bottom side, whereas the pulsator (2) is simultaneously connected with the air flow director (1) on the bottom side, and the segmented extension (4) is connected with the blower fan (5). The blower fan (5) constantly sends air to the director (1), through the segmented extension (4), distancing channel (3) and pulsator (2) directing the air towards a fruit shrub, thus shaking ripe fruits. In the course of the rotation of the pulsator (2) rotor (32), the pulsator (2) alternately sends air, in a single cycle, through the channels (6, 7 and 8), and then through the channels (9, 10 and 11) of the director (1), where the air flow leaving the pulsator (2) varies, achieving its power impact. It is possible to regulate the air blast power and speed over the connecting tube (78) by discharging part of the air which the blower fan (5) sends towards the director (1), into the atmosphere. The regulation is performed manually with the lever (81). Thus, regulation of the air blow power impact on a fruit shrub is obtained. When using the device for harvesting soft fruit, two devices are used simultaneously, positioned in such way that there is a row of shrubs between them.
