Description

Rake-shaped sickle

Technical Field

The utility model relates to an agricultural implement technical field that mows, specifically speaking relates to a harrow shape hook.

Background

The sickle is a rural mowing farm implement and comprises a blade and a wood handle, when mowing, one hand is needed to hold the upper end of a grass stalk, the other hand is needed to swing the sickle to cut off the grass stalk, and the action needs to be stood over greatly and stood up, and is very hard.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a harrow shape hook mows more laborsavingly, more high-efficient.

The utility model discloses a technical scheme that harrow shape hook adopted is:

a rake-shaped sickle comprises a sickle body and a sickle handle, wherein the sickle body comprises a connecting part and a plurality of rake tooth parts arranged side by side, the tail ends of the rake tooth parts are connected to the connecting part, gaps are arranged between the adjacent rake tooth parts, the width of each gap is gradually reduced from one side of the front end of each rake tooth part to one side of the tail end of each rake tooth part, and at least one side of each rake tooth part is edged to form a cutting edge; connecting portion are located to handle of a knife one end, and the other end slope upwards extends.

Preferably, at least the front end of the cutting edge forms a serration.

Preferably, among the rake teeth, the single-side blades of the rake teeth on both sides form cutting edges, and the double-side blades of the rake teeth in the middle form cutting edges.

As a preferred scheme, an included angle between the cutter body and the cutter handle is an acute angle.

Preferably, the front end of the rake tooth part is tilted upwards.

Preferably, the rake teeth are arranged in parallel at equal intervals.

Preferably, the rake teeth part is provided with a reinforcing rib.

As a preferred scheme, the handle is formed by bending and enclosing a metal sheet, a through groove is formed in the middle of the handle, and the diameter of the through groove is gradually reduced from top to bottom.

As the preferred scheme, still include handheld handle, handheld handle one end stretches into logical inslot to with logical groove interference fit.

Preferably, the cutter body and the cutter handle are integrally formed.

The utility model discloses a rake-shaped sickle's beneficial effect is: when mowing, an operator waves the rake-shaped sickle, grass stalks enter the gap between the adjacent rake tooth parts, the rake-shaped sickle continuously moves, the grass stalks move from one wider end to one narrower end of the gap, and the grass stalks are cut by the cutting edge in the moving process, so that mowing action is completed. The action is more labor-saving because the bending range is small when the mowing action is finished, and the mowing efficiency is higher because the swinging stroke of the rake-shaped sickle is longer.

Detailed Description

The invention will be further elucidated and described with reference to the following embodiments and drawings in which:

referring to fig. 1, 2 and 3, a rake sickle comprises a sickle body 10 and a sickle handle 20.

The cutter body 10 comprises a connecting part 11 and a plurality of rake teeth parts 12 arranged side by side, wherein the tail ends of the rake teeth parts 12 are connected to the connecting part 11. A gap 13 is arranged between the adjacent rake teeth 12, and the width of the gap 13 is gradually reduced from the front end side of the rake teeth 12 to the tail end side of the rake teeth 12. At least one side of the rake teeth 12 is edged to form a cutting edge 121. One end of the knife handle 20 is arranged on the connecting part 11, and the other end extends upwards in an inclined mode.

At least the front end of the cutting edge 121 forms a serration 122. When mowing, the grass stalks entering the gap 13 are cut by the saw teeth 122; especially, the sawteeth 122 are in point contact with the grass stalks when the sawteeth 122 are used for cutting the grass stalks with large diameters, and compared with a line contact mode of the cutting edge 121, the resistance is smaller, the cutting effect is better, and therefore, the labor can be saved. Since the width of the gap 13 affects the processing of the serrations 122, the length of the serrations 122 does not exceed one-half of the length of the cutting edge 121 in the present embodiment.

In the plurality of rake teeth 12, the cutting edges 121 are formed by the single-sided cutting edges of the rake teeth 12 located at both sides, and the cutting edges 121 are formed by the double-sided cutting edges of the rake teeth 12 located in the middle.

The rake teeth 12 are arranged in parallel and at equal intervals. The number of rake teeth 12 is preferably 8. Wherein, the front end of the rake tooth part 12 gradually increases in width from the end. In another embodiment, a plurality of the rake teeth 12 are arranged in a fan shape, wherein the front ends of the rake teeth 12 are aligned.

The included angle between the cutter body 10 and the cutter handle 20 is an acute angle. Specifically, the included angle is 72-78 degrees. This arrangement is mainly used to make the angle between the blade body 10 and the ground approximately parallel when mowing. Preferably, the front end of the rake teeth 12 is tilted upward. The upwarp angle is 3 °.

The rake teeth part 12 is provided with a reinforcing rib. The reinforcing ribs extend along the length direction of the rake teeth 12 to improve the rigidity of the rake teeth 12.

The handle 20 is formed by bending and surrounding a metal sheet. A through groove 21 is formed in the middle of the knife handle 20, and the diameter of the through groove 21 is gradually reduced from top to bottom. The harrow-shaped sickle further comprises a handheld handle, and one end of the handheld handle extends into the through groove 21 and is in interference fit with the through groove 21.

The knife handle 20 is provided with a limiting hole 22. The stopper is inserted into the handle from the stopper hole 22, thereby further restricting the movement of the handle in the axial direction of the through-groove 21.

In the above embodiment, the cutter body 10 and the cutter handle 20 are integrally formed. Specifically, the cutter body 10 and the cutter handle 20 are punched and then bent to form a semi-finished product, and then the semi-finished product is ground to obtain a finished product.

The utility model discloses a harrow shape hook during mowing, the operator waves harrow shape hook, and the stalk of grass gets into the clearance 13 between the adjacent harrow tooth portion 12, and harrow shape hook continues to move, and the stalk of grass moves from clearance 13 broad one end towards narrower one end, removes the in-process and is cut by cutting blade 121 to the completion action of mowing. The action is more labor-saving because the bending range is small when the mowing action is finished, and the mowing efficiency is higher because the swinging stroke of the rake-shaped sickle is longer.

It should be finally noted that the above embodiments are only intended to illustrate the technical solutions of the present invention, and not to limit the scope of the present invention, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present invention can be modified or replaced with equivalents without departing from the spirit and scope of the technical solutions of the present invention.
