Abstract

The utility model discloses a rolling type sickle. A blade on a sickle body is provided with a left circular cutting wheel and a right circular cutting wheel; sharp cutting edges are arranged on the peripheries of the cutting wheels; the left cutting wheel and the right cutting wheel are mounted on the blade through main shafts in parallel; no gap is formed between the cutting edges of the left cutting wheel and the right cutting wheel; the diameters of the cutting edges of the cutting wheels are greater than the width of the blade. Due to the use of the lever principle, straws of crops are cut off between the cutting edges of the two cutting wheels in a rolling manner, so that the harvesting aims of saving the labor and increasing the speed are fulfilled; furthermore, a threaded leather sleeve is arranged at a handheld end of a sickle rod, so that slippage can be avoided when a user holds the sickle, the user feels more comfortable, and the fatigue of a hand can be relived.

Description

Roller reaping hook

Technical field

The utility model relates to agricultural tools field, and one roller reaping hook specifically.

Background technology

Reaping hook is commonly called as cutter, in order to agricultural tools such as harvester for rice wheat maize straws, is in addition west people usually bending sword to be called to reaping hook with wooden forming by cutter hub, is the present widely used agricultural tools in China rural area;

Reaping hook is by cutter hub and wooden forming, cutter hub one side is with sharp blade and wooden meeting at right angles shape, hold in use hilt, the root that blade on cutter hub is placed on agricultural crop straw firmly pulls back, make stalk and root disconnect the object that reaches harvesting, in the process pulling back due to the large increase resistances of stalk lifting surface area of the blade on cutter hub and crops, stalk could be cut off by very large strength, the hand hilt of will holding with a firm grip just can make strength, harvesting 0.07 hectare corn needs long time, because need to use very large strength when harvesting, of long duration, the hand of holding hilt can be numb, arm turns sour, waist is pain very, at this moment the rest of just need to stopping, will affect like this speed of harvesting,

There is large-scale harvesting machinery in China rural area at present, advantage is time saving and energy saving, shortcoming is to be subject to environmental limit in ground, as rain in muddy, little and the crops of the area on harvesting ground is blown over by the wind, grain header cannot be worked like this, only have and complete harvesting with manpower reaping hook, especially have many uses at the stalk of China northeast crops, be used for winter warming oneself, it is indispensable cooking and feeding ox, can only receive grain and stalk is pulverized and can not be utilized in the ground with large-scale harvesting, large-scale grain header is suitable for large-scale farm and large area base, being not suitable for rural area small size uses.

Summary of the invention

This uses novel object is that the blade on reaping hook is changed into two roller cutting wheels, make agricultural crop straw from rolling and cut the object that reaches harvesting between two cutting wheel circular blade, reduce resistance and utilize the principle of lever, can reduce strength over half one roller reaping hook;

It comprises described roller reaping hook: cutter hub, knife bar and screw-type handle form;

It comprises described cutter hub: blade, left cutting wheel main shaft, left cutting wheel, right cutting wheel main shaft, right cutting wheel, left and right cutting wheel guard shield..

Described blade, is by cuboid, it is characterized in that front be oblique angle point of a knife with blade, central concave structure;

Described left and right cutting wheel, is characterized in that being around made up of with sharp blade circle;

Described knife bar is to be made up of steel pipe;

The screw-type handle of telling is to be made up of screw-type leather sheath.
