A Banana Bagging Device Based on Simply Supported Rigid Iris Mechanism

Abstract

The invention discloses a banana bagging device based on a simple support type rigid iris mechanism. The device includes a holding rod, the iris mechanism, a rubber band pushing ring and a rotary handle; the iris mechanism is composed of a lower ring, an upper ring and an iris unit; the lower ring is vertically installed on the top of the holding rod, a sliding guidance groove for the rotary handle to penetrate through is formed in the peripheral side, and a clamping position is formed at one end of the sliding guidance groove; the upper ring is placed in the lower ring, and the upper surfaceof the upper ring is overlapped with the top of the lower ring and can rotate relative to the lower ring; the rotary handle is hinged to the upper ring to drive the upper ring to rotate; the iris unitincludes N groups of rigid arc rod assemblies which are circumferentially distributed around the lower ring or the upper ring, and rubber bands are expanded by all expansion columns of the iris unit.The rubber band pushing ring is positioned on the upper ring and is concentric to the upper ring; after a button on the holding rod is pressed down, the rubber band pushing ring can be ejected upwardin a certain distance to push out the rubber bands. By means of the banana bagging device, the labor intensity of mounting the rubber bands can be lowered for farmers, and the working efficiency of bagging bananas can be improved.

Description

technical field [0001] The invention relates to the technical field of agricultural equipment, in particular to a banana bagging device based on a simply supported rigid iris mechanism. Background technique [0002] After the bananas are eared and have completed the processes of whole bunch, flower thinning, fruit thinning, and bud removal, the fruits should be protected by bagging. The function of bagging is mainly to avoid dust contamination, increase fruit weight, shorten banana production cycle, and reduce damage caused by pathogens, insects, small animals, leaves, pillars and harvesting and handling to fruits. It is an important production process to improve banana fruit. [0003] At present, at home and abroad, workers generally rely on workers to climb ladders to complete banana bagging manually, which has low work efficiency, high labor intensity and labor cost. Many manufacturers in the market have provided various banana bagging devices. The most common way is to ...

AI Technical Summary

Problems solved by technology

[0004] However, the problem of how to install the rubber band more conveniently has not been well resolved, so that the existing bagging device has not been widely used

Since the flexibility of the rubber band used should not be too large, otherwise it will affect the reliability of bagging and fixing, so a large force needs to be applied during the expansion of the rubber band; during installation, the user needs to manually hang the rubber band on multiple ( Generally, there are 6 fixed columns distributed in a circle, and the diameter of the circle can reach more than 450mm. The operation is difficult and time-consuming, which reduces the work efficiency.
