Air blast soft fruit harvesting device

摘要

The present invention is directed to the problem of harvesting soft fruit such as strawberries, blackberries, blueberries and blackcurrants. So far this task has been generally performed manually, which was and still is extremely hard work, involves a large number of workers and is may furthermore be slow and unhygienic. The prior art provides machines which are capable of harvesting fruit, however in many cases the fruit is damaged. The present invention is directed to the use of harvesting using blasts of air applied to the fruit, and provides a fruit harvesting device comprising an air flow director, pulsator, distancing channel, segmented extension and blower fan assembly. The distancing channel is connected with the segmented extension on the top side and with the pulsator on the bottom side, whereas the pulsator is simultaneously connected with the air flow director on the bottom side, and the segmented extension is connected with the blower fan. The blower fan constantly sends air to the director, through the segmented extension, distancing channel and pulsator directing the air towards a fruit shrub, thus shaking ripe fruits. In the course of the rotation of the pulsator rotor, the pulsator alternately sends air, in a single cycle, through the channels, and then through the channels of the director, where the air flow leaving the pulsator varies, achieving its power impact. The present invention provides for the regulation of the air blast power and speed over the connecting tube by discharging part of the air which the blower fan sends towards the director, into the atmosphere. The regulation is performed manually with the lever. Thus, regulation of the air blow power impact on a fruit shrub is obtained. When using the device for harvesting soft fruit, two devices may be used simultaneously, positioned in such way that there is a row of shrubs between them.
