Description

Hand-held type sugarcane removes leaf machine

Technical Field

The utility model belongs to the field of agricultural machinery, and particularly relates to a handheld sugarcane leaf removing machine.

Background

When the sugarcane is planted, the sugarcane is generally mastered to be stripped in the middle ten days of August for several times until the harvest period. Generally, the peeling is performed once every 10 to 15 days, and the peeling is performed 3 to 4 times. Too many sugarcane leaves, especially the old lower leaves absorb part of nutrients, and the old leaves have hormones growing transversely, which is not favorable for the longitudinal development of the sugarcane. Meanwhile, the old leaves are stripped, so that parasitism of insect pests can be prevented.

At present, most sugarcane farmers still use an old manual operation mode in the sugarcane leaf peeling process, and the labor intensity is high and the efficiency is low. At present, there are several sugarcane leaf stripping machines in the agricultural machinery market, can improve productivity by a wide margin in the application, reduce intensity of labour, but these several machines are high in cost, and are bulky and heavy, just carry out the leaf stripping after cutting the sugarcane and receiving when using, do not regard whether the sugarcane is damaged, therefore be not suitable for the sugarcane in the planting.

The existing leaf peeling tools used in large quantities basically knock down sugarcane leaves by using a wood rod, or a U-shaped iron sheet is arranged in front of the wood rod, one sugarcane needs to peel one side and then peel the leaves of the other side, the two methods are easy to cause the problem of hand exertion due to long-time operation, and the sugarcane is easy to be cut off due to the fact that the angle between the iron sheet and the sugarcane is too large, so that the efficiency is reduced and the damage rate is increased. Application number 201810429210.0 discloses a portable preceding sugarcane stripper, adopts motor drive, 2 semicircle leaf barking knives to form modes such as annular cutter and strip the dead leaf of sugarcane, and it is fast to shell the leaf, laborsaving, and it is clean to shell the leaf, does not harm the sugarcane. Because this leaf stripping machine is equipped with the inclined blade, the risk that the misoperation still can harm the sugarcane to the sugarcane need be wrapped to the use of this device every time, can only handle a sugarcane once, has improved the speed of stripping the leaf, but per mu sugarcane volume is very big, once handles one, and the time that the totality will consume still is more.
