Description

Technical Field

[0001] The present application relates to the technical field of sickles, and in particular to a high-strength and durable sickle. Background Art

[0002] The sickle, as a simple agricultural tool, is widely used in my country.

[0003] Related technology can refer to the Chinese patent with publication number CN216795741U, which discloses an agricultural harvesting sickle, including a knife bar, one end of the knife bar is hingedly connected to a handle, the knife bar and one side of the handle have a fixing component, one end of the knife bar is rotatably connected to a knife body, and a hole is provided on one side wall of the knife body, a countersunk hole is provided on one side wall of the handle, and a screw is arranged in the countersunk hole, and a first threaded hole and a second threaded hole matching the screw are respectively provided at one end of the knife bar.

[0004] The existing sickle is basically the same as the above sickle, which consists of a knife body and a knife bar. The knife body is sharpened for cutting operation. When the edge is blunt, the cutting operation is not smooth. When the operator increases the force for cutting, the knife body is easy to slip and cut the hand, which is quite dangerous. Utility Model Content

[0005] In order to improve the safety of the sickle, the present application provides a high-strength and durable sickle.

[0006] The high-strength and durable sickle provided in this application adopts the following technical solution:

[0007] A high-strength and durable sickle comprises a blade body and a blade rod, wherein the blade body comprises a blade back and a blade edge, wherein the blade edge is sharpened on one side to form an inclined blade edge, wherein one side of the blade edge close to the blade back is higher than the other side, the blade edge is located above the blade edge, and the bottom of the blade edge is set to be a plane to form a grinding surface.

[0008] By adopting the above technical solution, the existing sickle blades are basically double-sided, and the cross-section of the blade is "V" shaped. During normal cutting, the upper and lower blades cut at the same time. When the blade is blunt, the cutting force becomes weak, and it will cause a difference in the cutting force of the upper and lower blades. The operator needs to increase the force to cut, and when the operator exerts force according to his own habits, the direction of the force is upward, which will increase the cutting force of the lower blade. In this way, during the cutting process, the upward cutting force of the blade will be greater than the downward cutting force, and the blade body as a whole will slide up, which is easy to cut the hand. The blade body in this application is single-sided, with an inclined blade on the upper side and a flat grinding surface on the lower side. When cutting, only the upper blade generates an inclined downward cutting force, and the lower grinding surface generates very little cutting force on the object. Even when the blade is blunt, the cutting force of the blade is still greater than the cutting force of the ground surface below. Therefore, even if the operator increases the force, the cutting force generated below the blade is unlikely to be greater than the cutting force above, or the difference between the two will not be too large. Therefore, the blade is not easy to slide, thereby improving the overall safety of the sickle.

[0009] Preferably, the knife body is fixedly connected to the knife rod.

[0010] By adopting the above technical solution, the connection strength between the cutter body and the cutter rod is improved, thereby increasing the overall service life.

[0011] Preferably, a reinforcing rib is provided on a side of the connection between the knife rod and the knife body facing the cutting edge.

[0012] By adopting the above technical solution, the reinforcing ribs further increase the connection strength between the blade and the blade rod, reduce the possibility of the two being separated, and extend the service life. In addition, the blade rod is provided with reinforcing ribs on one side. When cutting, the reinforcing ribs protrude from the upper surface, and the lower surface is flat and will not affect the cutting of the blade.

[0013] Preferably, two connecting pieces are integrally provided at the upper end of the knife rod, a connecting gap for connecting with the knife body is formed between the two connecting pieces, and the knife body is fixed in the connecting gap.

[0014] By adopting the above technical solution, the knife body is fixed in the connection gap, and the two sides of the knife body are fixedly connected to the two connection pieces respectively. The connection piece area between the knife body and the knife rod is larger, thereby further improving the connection strength between the two.

[0015] Preferably, the two connecting pieces are integrally fixedly connected at one end facing away from the blade body.

[0016] By adopting the above technical solution, the two connecting pieces are connected as one body, thereby improving the overall strength.

[0017] Preferably, the blade body is arranged in an arc shape.

[0018] By adopting the above technical solution, the knife body is arc-shaped, the strength of the knife body is increased, the contact surface is reduced during sharpening, and sharpening is convenient and quick.

[0019] Preferably, an anti-slip grip is provided on the knife bar.

[0020] By adopting the above technical solution, the anti-slip handshake increases the gripping force between the operator and the knife bar, prevents slipping, and improves safety.

[0021] Preferably, the side of the end of the blade back facing the grinding surface is located in the same plane as the grinding surface, and an arched dividing line is formed at the connection between the upper surface of the blade edge and the blade back.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. The blade is sharpened on one side, the lower surface of the blade is flat-ground, and the upper edge is obliquely ground. When the edge is blunt, it is not easy to slide up and cut your hand;

[0024] 2. There are reinforcing ribs at the connection between the blade and the handle, and the connection structure between the blade and the handle is more stable, which improves the durability of the sickle. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The present application is further described in detail below in conjunction with all the accompanying drawings.

[0031] Example

[0032] The present application embodiment discloses a high-strength and durable sickle, referring to Figures 1 to 3 , comprising a tool body 1 and a tool rod 2.

[0033] Reference Figures 1 to 3The blade body 1 is quenched as a whole to improve the hardness and wear resistance of the blade body 1. The blade body 1 is arranged in an arc shape, and the blade body 1 includes a blade back 11 and a blade edge 12. When the blade body 1 is cutting, the blade back 11 is horizontal, the blade edge 12 is inclined, and an arched dividing line 13 is formed at the connection between the blade edge 12 and the blade back 11. The side of the blade edge 12 close to the blade back 11 is higher than the other side. When the blade edge 12 is cutting, the blade edge 12 will generate an inclined downward cutting force on the object to be cut, so that the sickle is not easy to slide up during cutting, cut the hand, and improve safety.

[0034] Reference Figures 1 to 3 , the blade 12 includes an upper surface and a lower surface. The upper surface of the blade 12 is sharpened on one side to form a blade 121, and the blade 121 is inclined in the same direction as the blade 12, which is convenient for cutting. The lower surface of the blade 12 is set to be a plane to form a grinding surface 122. The lower surface of the end of the blade back 11 away from the blade 12 is located in the same plane as the grinding surface 122. When cutting, only the upper blade 121 generates a cutting force that is inclined downward, and the lower grinding surface 122 generates very little cutting force on the object. Even when the blade 121 is blunt, the cutting force of the blade 121 is still greater than the cutting force of the lower grinding surface 122. Therefore, even if the operator increases the force, the cutting force generated at the lower side of the blade body 1 is unlikely to be greater than the cutting force at the upper side, or the difference between the two will not be too large, so the blade body 1 is not easy to slide up, thereby improving the overall safety of the sickle.

[0035] Reference Figures 1 to 3 Two connecting pieces 22 are provided at the connection between the upper end of the blade rod 2 and the blade body 1, and a connecting gap 23 is formed between the two connecting pieces 22. The connecting piece 22 is fixedly connected to the blade body 1 on the side facing away from the blade body 1. That is, the connecting gap 23 is "U"-shaped. The blade body 1 is fixed in the connecting gap 23, and the two connecting pieces 22 are respectively located on both sides of the blade body 1 and are fixedly connected to the blade body 1. The connecting piece 22 and the blade body 1 can be connected by laser welding to improve the connection strength.

[0036] Reference Figures 1 to 3 , wherein one or more reinforcing ribs 21 are provided on the connecting piece 22 facing the cutting edge 121, thereby improving the connection strength between the blade body 1 and the blade rod 2 and improving durability. The reinforcing rib 21 is provided on one side, and when cutting, the reinforcing rib 21 protrudes from the upper surface of the blade body 1, and the lower surface of the blade body 1 is flat and does not affect the cutting of the blade body 1.

[0037] Reference Figures 1 to 3 An anti-skid grip 24 is provided at one end of the knife bar 2 away from the knife body 1. The anti-skid grip 24 can be made of rubber or other materials to increase the friction between the operator and the knife bar 2 to prevent the sickle from loosening from the hand during operation and causing an accident.

[0038] The implementation principle of the high-strength and durable sickle in the embodiment of the present application is as follows: the operator holds the knife bar 2 with one hand, and makes the cutting edge 121 located above the grinding surface 122. The operator pulls the object to be cut with the other hand, swings the sickle to cut the object to be cut, and the inclined cutting edge 121 applies an inclined downward cutting force to the object to be cut, so that the sickle is not easy to slip and injure the hand.

[0039] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
