Abstract

The utility model discloses an open-close type plastic crank reaping sickle with a changeable knife edge, which pertains to the technical field of agricultural tools. The reaping sickle disclosed by the utility model is sharp as well as requires no sharpening, and the angle between the head of the sickle and the handle can be adjusted freely; the reaping sickle has the advantages of small volume and light weight and is easy and safe to carry; by using the reaping sickle, labor intensity can be reduced, and reaping efficiency can be improved. The reaping sickle of the utility model can conveniently replace knife edge, realize adjustment to the optimized angle between the head of sickle and the handle by round staggered gears bumped on the two sides of the sickle head and two round staggered gears concaved inside an elbow and the adjustment of a locking wheel; the open-close can be realized between the head of the sickle and the handle by the adjustment of the locking wheel, thereby reducing the bending of the body while reaping. The plastic crank reaping sickle of the utility mode has the advantages of simple structure, being easy to manufacture and being safe to use, which can reduce labor intensity and improve working efficiency and is a historical reform of traditional reaping sickle.

Description

Replaceable blade open-close type crank plastics harvesting sickle

Technical field

The utility model belongs to the rural labor technical field of tools, relates to a kind of replaceable blade open-close type crank plastics harvesting sickle.

Background technology

The harvesting sickle is a kind of important tool of rural labor, and traditional harvesting sickle is to be made of iron sickle head and wood handle, the right angle that sickle head and handle become to fix, and the figure is special more greatly, heavier, and labour intensity is big, and efficiency is low, carries also dangerous.

Summary of the invention

It is sharply need not whet a knife again that the purpose of this utility model provides a kind of, and the volume that can adjust angle between sickle head and handle arbitrarily is little, in light weight, reduce labor intensity, improve harvesting efficiency, harvesting sickle safe to carry.

For achieving the above object, the utility model has adopted following technical scheme: it comprises can change blade easily, by the circular tooth gear of sickle head both sides projection and two recessed circular tooth gears of elbow inboard, adjustment by locking wheel again, can reach the best angle of adjusting between sickle head and handle, and the adjustment by locking wheel can realize the folding between sickle head and handle, thereby reduces to gather in the special figure and the bodily form of sickle; By the design of crank, the intensity of having bent over when having alleviated harvesting is selected the application of plastic material by sickle head, elbow and handle, has alleviated the weight of harvesting sickle widely.

The utility model is simple in structure, is easy to manufacture, and is safe in utilization, reduces labor intensity, and raises labour efficiency, and is the historical change of tradition harvesting sickle.

Embodiment

Below in conjunction with drawings and Examples the utility model is further described.

As shown in the figure, the utility model comprises replaceable blade (Fig. 4), the circular tooth gear (Fig. 5) of plastics, plastic latch bearing up pulley 9, plastic elbow 3, plastics sickle head 2, bent handle plastics grip 10, bent handle plastics grip 12 and bent handle plastics grip 13, grip hanging hole 11 is the utility model holes of putting away the sickle, unclamping of plastic latch bearing up pulley 9 is replaceable blade (Fig. 4), and the degree of tightness of adjusting plastic latch bearing up pulley 9 gets final product folding plastics sickle head 2; Curved design by plastics crank (Fig. 3) alleviates the intensity of bending in the time of can reaching harvesting, the profile of bent handle plastics grip 10,12,13 embodies the hommization idea.
