Abstract
The utility model relates to a novel time-saving and labor-saving sickle in the field of manual tools for agriculture production. The novel time-saving and labor-saving sickle comprises a knife body and a knife handle, wherein the knife edge part of the knife body comprises a hook edge part and an oblique edge part; an included angle alpha between the oblique edge and the knife handle is between 105 and 110 degrees; a flat edge part is arranged between the oblique edge part and the knife handle; a right angle is formed between the flat edge and the knife handle; and an included angle beta between the oblique edge and the extended line of the flat edge is between 15 and 20 degrees. Because the included angle between the oblique edge part and the knife handle is 110 degrees, in the process of reaping, friction between the sickle and crops changes from the original static friction to sliding friction, resistance is greatly reduced, and time and labor are saved.
Description
Technical field
The utility model relates to a kind of agricultural production hand-operated tools field, a kind of time saving and energy saving novel reaping hook of saying so more specifically.
Background technology
China is large agricultural country, and crops are of a great variety, such as high and thick single plant corn, sunflower, many short and small plant paddy, wheat etc.Peasant's harvesting tool mainly is a reaping hook, the reaping hook of production and sales mainly contains two kinds of patterns on the market now, promptly flat sword sickle and hook sword sickle, the angle that forms between the blade of these two kinds of reaping hooks and the hilt all is the right angle, in use, the frictional force that produces is friction of rest power when blade and the cutting of plant face, so just needs the user just can finish the process of cutting off with bigger strength.
Summary of the invention
The purpose of this utility model is that a kind of economical and practical, laborsaving timesaving reaping hook will be provided.
The purpose of this utility model is achieved in that
A kind of time saving and energy saving novel reaping hook comprises cutter hub and handle of a knife, and the knife edge part of described cutter hub comprises that the hook blade divides and oblique blade branch, and tiltedly the angle α of sword and handle of a knife is 105-110 °;
Set up flat blade branch between described oblique blade branch and the handle of a knife, at right angles, tiltedly angle β is 15-20 ° between sword and the flat sword extended line between flat sword and the handle of a knife;
The angle α of described oblique sword and handle of a knife is 110 °;
Angle β is 20 ° between described oblique sword and the flat sword extended line.
Owing to adopt said structure, this reaping hook had the following advantages:
Because tiltedly angle is 110 degree between blade branch and the handle of a knife, when harvesting, the friction between cutter and the crops becomes sliding friction by original friction of rest, significantly reduces resistance, and is time saving and energy saving.

Fig. 2 is second kind of structural entity schematic diagram of the utility model.
Embodiment
A kind of time saving and energy saving novel reaping hook comprises cutter hub 1 and handle of a knife 2, and the knife edge part of described cutter hub 1 comprises hook sword 3 parts and oblique sword 4 parts, and tiltedly sword 4 is 105-110 ° with the angle α of handle of a knife 2, and angle α is preferably 110 °.Set up flat sword 5 parts between described oblique sword 4 parts and the handle of a knife 2, at right angles, tiltedly angle β is 15-20 ° between sword 4 and flat sword 5 extended lines between flat sword 5 and the handle of a knife 2, and angle β is preferably 20 °.
First kind of cutter hub total length is 18 centimetres, wherein tiltedly sword 4 parts are 13 centimetres, hook sword 3 parts are 5 centimetres, tiltedly sword 4 is 110 degree with the angle α of handle of a knife 2, hook sword 3 is 150 degree angles with oblique sword 4, the oblique sword 4 of this cutter utilization is cut disconnected plant with plant surface with sliding type, is used for the harvesting of short and small many plants such as paddy, wheat more, also can be used for single plant harvesting.
Second kind of cutter hub total length is 18 centimetres, and wherein flat sword 5 parts are 2 centimetres, and tiltedly sword 4 parts are 11 centimetres, and hook sword 3 parts are 5 centimetres.Be an angle of 90 degrees between flat sword 5 and the handle of a knife 2, tiltedly sword 4 is 20 degree with the extended line angle β of flat sword 5, and hook sword 3 is 150 degree angles with oblique sword 4.This cutter utilizes the flat sword 5 and the outer drift angle of oblique sword 4 to cut the shell of plant with minimum force, and the sword 4 that retreads is cut disconnected plant along its otch with sliding type.This cutter mainly is suitable for the harvesting of corn, single plant that sunflower is contour and thick, also can be used for other crops harvesting.
