Description

Flue-cured tobacco topping device

Technical Field

The utility model belongs to the facility field is planted to the flue-cured tobacco, concretely relates to flue-cured tobacco device of pinching.

Background

In the flue-cured tobacco cultivation, the top growth advantage can be controlled by topping, the root system development is promoted, the growth of the leaves is supplied by concentrating nutrient substances, the leaves are enlarged, the dry matter accumulation is increased, and the yield and the quality of the tobacco leaves are improved.

At present, the top of the tobacco plant is usually cut off by a cutter such as scissors, a knife or a sickle during topping, and the cut at the top of the tobacco plant is usually inclined to avoid top liquid accumulation. When a knife or a sickle is used for topping, a knife edge is required to be aligned with the stem above a tobacco plant, and then the knife is lifted from bottom to top to cut off the stem, so that the knife can be lifted upwards in an inclined mode to avoid damaging tobacco leaves, but some flue-cured tobacco varieties are high in length, so that the operation of lifting the knife by a tobacco grower is inconvenient, and the tobacco grower is very easy to fatigue.

SUMMERY OF THE UTILITY MODEL

In order to overcome the defect of the technical problem, the utility model provides a tobacco-curing topping device which can not hurt the tobacco leaves and can be operated more easily at the same time.

The technical scheme is as follows:

the utility model provides a flue-cured tobacco device of pinching, includes portion of gripping, connecting rod and sickle-shaped blade, the one end of connecting rod is provided with the portion of gripping, and the other end is provided with the blade, the portion of gripping is provided with the hole of gripping that supplies the finger to pass, the blade is crooked to the direction of the portion of gripping, be provided with the dodge board on the connecting rod, the dodge board is located between blade and the portion of gripping, the blade falls in the dodge board towards the orthographic projection of dodge board direction.

This design can be passed through the hole of holding by the finger and lightly control whole top-pruning device, only need from top to bottom inwards pull the top-pruning device when pinching, can cut off the tobacco plant top. And the cutter avoiding plate is arranged below the blade, so that the cutter avoiding plate can push the tobacco leaves open when the blade is obliquely downwards scratched, and the tobacco leaves are prevented from being scratched by the blade. The tobacco grower uses the device to topping, and is difficult tired, and work efficiency is high.

For storage convenience, the relative position between the knife avoiding plate and the blade can be designed to be adjustable, and two adjustable designs are provided as follows:

one, preferably, the knife avoiding plate is provided with a through hole, the connecting rod passes through the through hole of the knife avoiding plate, the periphery of the connecting rod is provided with threads, and two nuts matched with the threads are arranged on the periphery of the connecting rod and are respectively arranged at two ends of the knife avoiding plate.

According to the design, the position of the knife avoiding plate can be adjusted through the adjusting nut. When the knife avoiding plate is adjusted to be in contact with the blade, the knife avoiding plate can be conveniently carried and placed, and the blade is prevented from being scratched by the blade accidentally when not in use.

Preferably, the knife avoiding plate is provided with a through hole, the connecting rod passes through the through hole of the knife avoiding plate, the knife avoiding plate is provided with a sliding rod, one end of the sliding rod is connected with the knife avoiding plate, the other end of the sliding rod passes through the through hole arranged on the holding part, and the tail end of the end extending to the holding part is provided with a handle; the sliding rod is provided with a rubber ring at the position close to the grip.
