Description

Portable fruit tree bagging device

Technical Field

The invention relates to an agricultural machinery processing technology, in particular to a portable fruit tree bagging device.

Background

The fruit bagging technology enables the economic crops such as apples, pears, grapes and the like to realize pollution-free production, and the bagging technology can promote the color development background of the fruit peel anthocyanin, so that the coloring of the fruits is greatly improved, and the fruits after the bags are removed are bright in color and beautiful. And the bagged fruits can prevent the infection of diseases and pests and reduce the harm of the diseases and the pests. In addition, the fruit rot is less, and the fruit rot is less, so that the fruit tree is favorable for storage and transportation.

And in order to satisfy the use of bagging technique, need carry out flower thinning, fruit thinning, reasonable load to the fruit tree in the orchard before the bagging: artificial supplementary pollination or bee releasing in the flowering period is needed in the orchard; strictly thinning flowers and fruits before bagging, adjusting the tree load, and implementing flower and fruit fixing technology. 1 strong inflorescence is reserved for tree species such as apples and pears at the interval of 20-25CM, 1 fruit is reserved for each 1 inflorescence, 1 fruit is reserved for peaches at the interval of 10-15CM, 1 ear is reserved for each new fruiting shoot of grapes, 50-60 grains are reserved for each ear, and 1 month is after flower falling.

After the steps are completed, when the young fruits are processed by the bag, the young fruits need to be positioned in the center of the bag body and suspended in the bag to prevent the bag body from rubbing the fruit surface, then redundant air in the bag is extruded out, the inner space of the bag is kept in a state that the fruits cannot be in contact with the bag until the fruits grow to be ripe, and finally the bag is sealed. (the orchard management is completed to ensure that the weight difference of the single fruit after ripening of each fruit does not exceed 20g, so that the external contour difference of each apple is small)

It should be noted that the reason why the space inside the pocket needs to be controlled is because: if the internal space of the bag is too large, the bag can swing under wind force when meeting wind force, the fruit bag can flap the fruits inside in the swinging process to cause fruit stems to fall or loose and sick insects at the bag opening to enter to cause plant diseases and insect pests, and the more the large water vapor is generated in the internal space, the certain influence can be brought to the fruits; if the internal space of the bag is too small, the fruits can contact with the bag wall in the growing process, so that the appearance of the apples is influenced, and the selling price of the apples is influenced.

The existing bagging machine can only realize active continuous tape supply and sealing, but cannot meet the requirement of controlling the space in the bag after bagging. Therefore, in actual bagging operation, manual bagging is mainly performed, but manual bagging mainly depends on work experience, and is highly subjective, so that the quality of each bagged bag cannot be guaranteed after being sleeved.
