Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is an improvement in a fruit stalk cutting and bag removal device that cuts the stalk of a harvested fruit with a bag and stalk and removes the covering bag. It is related to.

The fruit stalk cutting and bag removal device is provided with a fruit receiver on a conveyor that rotates endlessly, on which the harvested fruit with a bag and stalk can be placed in a state in which the fruit stalk protrudes downward. and a stalk cutting device that cuts the stalk of the fruit as it protrudes toward the lower surface of the fruit receiver and moves on the lower surface of the conveying process in which the fruit receiver supports the fruit and moves; A pressure-air blowing device that blows a river breeze was installed on the -I side of the fruit receiving part, and after cutting the fruit stem, the fruit was opened 1'7 by cutting the fruit stem. A compressed air is blown from below at the mouth of the bag to remove it by pulling the bag away from the fruit. However, this method involves cutting the 1lffi portion of the bag placed over the fruit by cutting the peduncle that protrudes to the lower surface of the fruit holder through a hole provided in the 1 fruit holder. Pressure air is blown into the bag from the opening part to separate the bag from the fruit. There is a problem in that bag removal becomes unreliable because the bag is blown away by pressure wind.

The purpose of the present invention is to solve this problem and to ensure that bag removal can be carried out reliably and efficiently using pressure air blown from the underside of the fruit receiver. .

In order to achieve this object, the fruit stalk cutting and bagging device according to the present invention conveys the harvested fruit with a bag and stalk to a conveyor that moves endlessly. A fruit receiving part is provided to support the fruit in a state in which the fruit is supported, and a fruit receiving part is provided on the lower surface side of the movement trajectory in which the fruit receiving part supports the fruit and moves. In a fruit stalk cutting and bag removing device that includes a stalk cutting device and a pressure air blowing device that blows pressure air toward the upper surface side of a fruit receiver, the lower surface side of the movement trajectory of the fruit receiver is provided. At the position where the pressure air blowing device blows up the river wind, a fruit pushing device is provided which operates to lift the fruit placed on the fruit receiving portion and moving from the upper surface of the fruit receiving portion. It is characterized by the fact that
