Description

Technical Field

[0001] This utility model relates to the field of agricultural tools, and in particular to a novel sickle. Background Technology

[0002] The sickle, as an agricultural tool, is favored by people. However, with the development of agricultural machinery, its use has gradually decreased when harvesting conventional crops such as rice, wheat, and soybeans. It now plays a more auxiliary role in daily farm work, such as cutting branches. However, existing sickles can only cut relatively small branches. Some researchers have designed a cleaver with a saw blade for pruning garden branches, but this structure has certain limitations and cannot replace the sickle. Therefore, there is an urgent need for a new type of sickle. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model presents a novel sickle. An extended blade is incorporated into the basic sickle design, with a saw blade and / or a cleaver positioned on the side of the extended blade closest to the main body of the sickle. This design makes the sickle more convenient to use, eliminating the need to reverse the sickle in confined spaces. It combines the functions of a sickle with the ability to be used as a cleaver or saw.

[0004] Specifically, this utility model provides a novel sickle, including a sickle body, an extended blade, and an operating lever connection. The extended blade is disposed between the sickle body and the operating lever connection. The included angle between the sickle body and the extended blade is 90-105 degrees. The side of the extended blade closest to the sickle body is provided with serrations and / or a cutting edge. The cutting edge of the extended blade is not continuous with the cutting edge of the sickle body.

[0005] A further optimization of the technical solution of this utility model is that the extended blade is provided with serrations and / or a cutting edge on the side away from the sickle body.

[0006] In a further optimization of the technical solution of this utility model, the length of the extended blade is 1-1.5 times the length of the sickle body.

[0007] A further optimization of the technical solution of this utility model is that a stepped groove is provided on the back of the sickle body and the end of the extended blade away from the connection part of the operating rod, and a blade is provided on the stepped groove.

[0008] A further optimization of the technical solution of this utility model is that a shovel blade is provided on the back of the sickle body.

[0009] A further optimization of the technical solution of this utility model is that the extended blade body is provided with reinforcing ribs and a protective sleeve.

[0010] In a further optimization of the technical solution of this utility model, all the saw teeth are provided with saw blades on one side, and the saw blades of two adjacent saw teeth are arranged opposite each other.

[0011] In a further optimization of the technical solution of this utility model, the saw teeth are triangular or quadrilateral.

[0012] Compared with the prior art, the advantages of this utility model are as follows: By designing an extended blade and incorporating serrations and / or a cutting edge on the side closest to the main body of the sickle, the design of the sickle becomes more versatile and flexible in use. Furthermore, by placing the serrations and / or the cutting edge on the same side as the main blade, the environmental limitations associated with using the serrations are reduced. Combined with the cutting edge on the extended blade, it can also function as a chopping knife. By discontinuously setting the cutting edge of the extended blade and the main blade of the sickle, the weak points of the sickle can be avoided, preventing the blade from getting stuck in the object being cut at the junction of the main body and the extended blade, which would easily cause bending and deformation.

[0020] The following will be combined with the appendix Figure 1-4 The present invention will be further described below.

[0021] In response to the development of existing agricultural technologies and to improve the utilization rate of sickles and their application in the market, this technical solution is specifically designed to address the limitations of sickle use, such as... Figure 1As shown, a novel sickle is invented, comprising a sickle body 1, an extended blade 2, and an operating rod connecting part 3. The extended blade 2 is disposed between the sickle body 1 and the operating rod connecting part 3. The included angle between the sickle body 1 and the extended blade 2 is 90-105 degrees, preferably 90 degrees and 103 degrees. The 90-degree angle is relatively conventional for sickles, and this model is geared towards applications where sickles are used frequently. The 103-degree sickle body 1 structure is designed for applications involving messy branches, facilitating the reach and cutting of the sickle body 1. Furthermore, regarding the curvature of the sickle body 1, the preferred technical solution of this invention adopts a 30-160 degree arc structure. The 30-degree arc is smaller, and the 160-degree arc resembles a hook, making it more convenient to use. The extended blade 2 is provided with serrations 21 and / or a blade 22 on the side near the sickle body 1. The following are some preferred embodiments: First, as... Figure 2 and Figure 3 As shown, the overall structure is a serrated 21, allowing direct sawing of the object to be cut from one side of the sickle without switching the angle of the sickle. In existing technology, the serration 21 is located on the side of the extended blade 2 away from the sickle, requiring the sickle to be rotated 180 degrees to use it. Furthermore, the sickle body 1 requires a certain amount of space to move during sawing, placing higher demands on the environment. Secondly, as... Figure 1 and Figure 4 As shown, the upper part is the blade 22, and the lower part is the saw blade, with the length of the saw blade being greater than the length of the blade 22. The blade mainly serves the purpose of chopping. Third, the upper part is the saw blade, and the lower part is the blade 22. Compared with the second and third implementation methods, the former is superior to the latter. In order not to affect the strength of the sickle, the blade 22 of the extended blade 2 is not continuously set with the blade 22 of the sickle body 1. This design can avoid the weak points of the sickle and prevent the joint between the sickle body 1 and the extended blade 2 from getting stuck in the cut object, because getting stuck in the cut object at this point makes it easy to bend and deform.

[0022] Based on the above embodiments, such as Figure 2 and Figure 3 As shown, a serration 21 and / or a blade 22 are provided on the side of the extended blade 2 away from the sickle body 1. This implementation means that when the serration 21 structure is provided on the side of the extended blade 2 close to the sickle body 1, the side away from the sickle body 1 can be a saw blade structure or a blade 22 structure. Different models can be designed as needed to increase product diversity and improve the market competitiveness of the product while keeping the cost basically unchanged.

[0023] From the perspective of usability, the length of the extended blade 2 is 1-1.5 times the length of the sickle body 1. This design ensures the smoothness of the saw blade. Combined with the size of the sickle, it can ensure that the length of the saw blade is between 13-30CM. This proportional structure limit makes the overall appearance of the new sickle not compromised, and the functional design is more reasonable.

[0024] Another implementation of the technical solution of this application, such as Figures 2-4 As shown, a stepped groove 4 is provided on the back of the sickle body 1 and at the end of the extended blade 2 away from the operating lever connection part 3. A blade 22 is formed on the stepped groove 4. This design enables the sickle to function as a pusher, further increasing its flexibility. When space or distance is limited, the sickle can be directly pushed up using the operating lever to function as a pusher. The stepped groove is located along the length extension direction of the handle and the extended blade, making it easier to apply force. Preferably, the width of the stepped groove 4 is less than half the width of the extended blade 2, which is 4-5 cm wide.

[0025] Another implementation of the technical solution of this application, such as Figure 6 As shown, a shovel blade 41 is provided on the back of the sickle body. When the user is working, it can be used as a shovel to shovel grass or remove tall branches, making it more convenient to use.

[0026] Based on the above embodiment, to ensure the strength of the sickle, reinforcing ribs are provided on the extended blade body 2. These reinforcing ribs can be achieved through localized thickening, a perforated structure design to increase strength, or a standalone reinforcing rib structure. The extended blade body is made of high-carbon steel or saw blade steel, which provides high toughness and prevents bending during use.

[0027] The saw tooth structure used in the above embodiments of this application is such that all saw teeth have a single-sided cutting edge, and the cutting edges of two adjacent saw teeth 23 are arranged opposite each other. This design increases the sharpness of the saw teeth and facilitates the removal of sawdust. Furthermore, the saw teeth can be configured as triangular, quadrilateral, or a combination of both. When the triangular and quadrilateral structures are combined, the height of the triangular saw teeth is less than the height of the quadrilateral saw teeth, and the triangular and quadrilateral saw teeth are staggered. A quadrilateral structure is preferred. Figure 5 As shown, the quadrilateral structure includes a first saw blade 231, a second saw blade 232, and a third saw blade 233. The first saw blade 231 is connected to the third saw blade 233 through the second saw blade 232. This saw blade is used on a sickle to make the sickle sharper and more durable.

[0028] To increase the safety of the sickle, such as Figure 7As shown, a protective sleeve 5 is provided on the extended blade body. The protective sleeve has a U-shaped structure, and the side projection view of the U-shaped gap of the protective sleeve is a trapezoidal structure, so that the opening can clamp the handle of the extended blade body. The protective sleeve can be made of iron or hard plastic.

[0029] In a preferred embodiment, a bayonet-type bottle opener is also provided on the extended blade 2 to facilitate the user in opening the bottle cap.
