Description

Technical Field

[0001] This utility model relates to the field of land reclamation blade technology, and in particular to a high-strength land reclamation blade. Background Technology

[0002] In agricultural land reclamation, the tillage blade is a core component, and its performance directly affects the quality of cultivation and operational efficiency. With the modernization of agriculture, higher requirements are placed on the strength, durability, and stability of tillage blades. Developing high-strength and reliable tillage blades has become a key link in improving agricultural productivity.

[0003] Currently, most commercially available tillage knives use a single-structure blade that connects to tillage equipment via a handle. During operation, the blade's hardness and sharpness cut into the soil, and the equipment rotates the blade to perform functions such as tilling and breaking up the soil. These tillage knives typically only increase blade thickness or use conventional steel to ensure strength, without optimizing the blade structure.

[0004] In actual operation, existing tillage blades frequently encounter varying degrees of resistance and impact due to uneven soil texture. Traditional single-structure tillage blades lack effective reinforcement design and have insufficient structural strength, making them prone to bending and twisting deformation under external forces. Once the blade is deformed, it will be unable to maintain a normal working posture, resulting in inconsistent tillage depth, poor soil breaking effect, and consequently reduced tillage accuracy and efficiency. Therefore, a high-strength tillage blade is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a high-strength land reclamation blade, which aims to improve the problem that existing land reclamation blades are prone to bending and twisting deformation under external forces due to insufficient structural strength, resulting in the blade body being unable to maintain a normal working posture and reducing land reclamation accuracy and efficiency.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A high-strength land clearing knife includes a handle, a blade fixedly connected to the lower surface of the handle, a main cutting edge formed by a downwardly inclined side surface of the blade, a reinforcing component provided on the side wall of the handle, and a cutting component provided on the side wall of the handle.

[0008] The reinforcing component includes a first reinforcing rib and a second reinforcing rib. One side wall of the first reinforcing rib is fixedly connected to both sides of the blade, and the side wall of the second reinforcing rib is fixedly connected to both sides of the blade. Multiple ribs are fixedly connected between the first reinforcing rib and the second reinforcing rib. The first reinforcing rib and the second reinforcing rib are used to increase the thickness and rigidity of the blade, making it less prone to bending, twisting and deformation under force.

[0009] As a further description of the above technical solution:

[0010] The cutting assembly includes a cemented carbide block, the sidewall of which is fixedly connected to the edge of the main cutting edge. The cemented carbide block is used to quickly cut into hard soil while also preventing the cutting edge from chipping or breaking.

[0011] As a further description of the above technical solution:

[0012] Both sides of the handle are fixedly connected to buffer pads, and the handle has a mounting hole inside, the inner wall of which is circular.

[0013] As a further description of the above technical solution:

[0014] The edge of the main blade has multiple grooves, which are triangular in shape and recessed into the main blade.

[0015] As a further description of the above technical solution:

[0016] The blade handle is inclined downward at the end away from the main blade handle to form a secondary blade, which is used to perform secondary cutting on the soil left after the main blade has cut.

[0017] As a further description of the above technical solution:

[0018] The buffer pad is made of rubber and is used to protect the handle and reduce loosening and damage caused by vibration.

[0019] As a further description of the above technical solution:

[0020] The grooves are evenly arranged along the edge of the main cutting edge, and the grooves are used to reduce the cutting resistance of the tool.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, the thickness and rigidity of the blade can be increased by reinforcing rib one and reinforcing rib two, and multiple ribs further enhance the stability of the blade structure, making the blade less prone to bending or twisting deformation under these forces, ensuring the stability of the blade during operation, and solving the problem that some reclamation blades are prone to bending or twisting deformation under external forces due to insufficient structural strength, resulting in the blade body being unable to maintain a normal working posture and reducing reclamation accuracy and efficiency. The above structure improves the overall strength of the reclamation blade.

[0023] 2. In this utility model, the installed carbide block ensures the sharpness of the blade and guarantees the high efficiency of cutting. The secondary blade performs secondary cutting and crushing of the soil, improving the fineness of the soil. The groove makes the soil separation and discharge smoother, avoiding soil accumulation that affects the flatness of the land. The above structures work together to improve the cutting ability of the land reclamation blade. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1-4This utility model provides an embodiment of a high-strength land clearing knife, including a handle 1, a blade 2 fixedly connected to the lower surface of the handle 1, a main cutting edge 3 formed by a downwardly inclined side surface of the blade 2, a reinforcing component and a cutting component provided on the side wall of the handle 1, the reinforcing component including a first reinforcing rib 4 and a second reinforcing rib 5, the side wall of the first reinforcing rib 4 being fixedly connected to both sides of the blade 2, and the side wall of the second reinforcing rib 5 being fixedly connected to both sides of the blade 2, the first reinforcing rib 4 and the second reinforcing rib 5 are used to increase the thickness and rigidity of the blade 2, and play a role in dispersing the external force on the blade 2, so that the blade 2 is not easily bent or twisted under the cutting force and extrusion force of the soil, ensuring the stability of the blade 2 during operation ... Multiple ribs 6 are fixedly connected between the two ribs 5. The ribs 6 further enhance the connection strength between the first reinforcing rib 4 and the second reinforcing rib 5. The three work together to form a stable frame structure, which further improves the deformation resistance of the blade 2 and achieves the effect of enhancing the overall structural strength of the blade 2. Buffer pads 7 are fixedly connected to both sides of the handle 1. The handle 1 has a mounting hole 11 inside. The inner wall of the mounting hole 11 is circular and is used to connect with the reclamation equipment. The mounting hole 11 is a common connection structure and will not be described in detail here. The buffer pads 7 are made of rubber. Rubber has good elasticity and is used to absorb the vibration transmitted to the handle 1 when the blade 2 is working, reduce the loosening and damage of the handle 1 caused by vibration, and protect the connection stability between the handle 1 and the equipment.

[0033] Reference Figures 1-5 The cutting assembly includes a cemented carbide block 8, whose sidewall is fixedly connected to the edge of the main cutting edge 3. The cemented carbide block 8 is made of cemented carbide and its function is to quickly cut into harder soil, preventing chipping or breakage of the main cutting edge 3 when it directly contacts hard soil, thus extending the service life of the main cutting edge 3. Multiple grooves 9 are formed on the edge of the main cutting edge 3, each groove being triangular and recessed inwards. These grooves reduce cutting resistance; when the main cutting edge 3 cuts into the soil, the soil enters the grooves 9, dispersing the cutting force and reducing resistance during cutting, making the operation of the tillage knife easier. The end of the handle 1 furthest from the handle 1 is inclined downwards, forming a... The secondary cutting edge 10 is used to perform secondary cutting on the soil left after the main cutting edge 3, further breaking and refining the soil, thereby improving the quality of soil reclamation. The grooves 9 are evenly arranged along the edge of the main cutting edge 3. The evenly arranged grooves 9 can evenly distribute the cutting resistance, and together with the cutting motion of the main cutting edge 3, they can make the cutting process of the main cutting edge 3 more stable. The carbide block 8 works with the main cutting edge 3 to cut into the soil, ensuring cutting efficiency while protecting the main cutting edge 3. The secondary cutting edge 10 works with the cutting of the main cutting edge 3 to perform secondary processing on the soil. Together with the main cutting edge 3, it can improve the overall quality and efficiency of reclamation operations.

[0034] Working Principle: During reclamation operations, the blade 1 connects to the reclamation equipment via the circular mounting hole 11 inside the handle. When the equipment operates, power is transmitted to the handle 1, causing the blade 2 to rotate at high speed, enabling the main blade 3 and secondary blade 10 to cut into the soil, thus achieving the reclamation function. The carbide block 8 at the edge of the main blade 3, with its high hardness and wear resistance, can quickly cut into hard soil, rocks, or roots, effectively preventing blade chipping and breakage, ensuring the continuous sharpness of the main blade 3. The evenly arranged triangular grooves 9 on the edge of the main blade 3 change the contact pattern between the soil and the blade, making the soil easier to separate and expel during the cutting process, significantly reducing the adhesion and friction of the soil to the blade, reducing the cutting resistance of the tool, improving reclamation efficiency while reducing energy consumption. The secondary blade 10 is located at the end of the handle 1 furthest from itself, and after the main blade 3 completes the initial cut, it performs a secondary cut on the remaining soil, further... The process of breaking up soil clods and refining soil particles improves the flatness and looseness of the reclaimed land. During the high-speed rotation of the blade 2, it is subjected to various complex forces from the soil, such as cutting force, extrusion force, and friction force. At this time, reinforcing ribs 1 and 2 are fixed on both sides of the blade 2 to increase the thickness and rigidity of the blade 2. Multiple ribs 6 are connected between reinforcing ribs 1 and 2, further enhancing the stability of the blade 2 structure, effectively dispersing the external forces on the blade 2, preventing the blade 2 from bending or twisting, and ensuring that the reclamation blade maintains a stable working state under high-intensity operation. In addition, the rubber buffer pads 7 on both sides of the handle 1 can effectively buffer the vibration transmitted from the blade 2 to the handle 1 during the reclamation process, reduce the loosening and damage of the handle 1 caused by vibration, protect the connection structure between the handle 1 and the equipment, reduce operator fatigue, and extend the overall service life of the reclamation blade.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
