Description

Technical Field

[0001] The utility model relates to the technical field of movable blades for agricultural machinery, in particular to a straight-edged bent movable blade. Background Art

[0002] Currently, blade shapes for agricultural machinery moving blades on the market generally fall into two categories: curved and straight. Curved blades are generally only suitable for installation on disc-type cutterheads. Because their blades are not straight, their shape limits manufacturing complexity and high costs. These blades are also difficult to maintain and sharpen. Furthermore, due to their design, they require an installation angle close to 90°, which prevents proper guidance of the cut material, hindering its rapid entry into subsequent processing mechanisms such as ejection, pulverization, and shredding. Straight-edged blades on the market are generally only suitable for use on drum-type cutterheads. While simple and low-cost, straight-edged blades impose high requirements on the cutterhead where they are mounted, due to the angle at which the blades are used. Their complex shape also makes them difficult to manufacture. Furthermore, this angle causes the blades to wear more quickly, requiring frequent sharpening during use and reducing their lifespan. The blades are typically subjected to high-frequency hardening, which results in rapid wear and poor wear resistance. Utility Model Content

[0003] In response to the above-mentioned deficiencies in the prior art, the present invention provides a straight-edged bending movable knife, which uses the blade of a straight-edged knife to reduce manufacturing costs and facilitate later maintenance and grinding, and bends a certain angle at a suitable position of the movable knife to increase the strength of the blade.

[0004] In order to achieve the above-mentioned utility model purpose, the technical solution adopted by the utility model is:

[0005] A straight-blade bending movable knife comprises: a movable knife body, the movable knife body comprising: an integrally formed straight-blade section, the straight-blade section integrally connected to a bending section, a knife tip section provided at the bottom end of the bending section, the angle between the straight-blade section and the bending section being 152°, and the thickness angle of the knife tip section being 21°.

[0006] The advantages of this new invention over existing technologies include: using a straight-edged blade to reduce manufacturing costs and facilitate subsequent maintenance and sharpening. A curved angle at a suitable location on the movable blade increases blade strength. The angle between the straight and curved sections is 152°, and the thickness angle at the blade tip is 21°. This curved angle also forces the cut material to change its trajectory, accelerating its movement toward the desired direction and allowing it to quickly enter the next unit for further processing. Furthermore, the curved angle relative to the uncut material slows blade wear, reducing sharpening frequency and extending the life of the movable blade, thus reducing future costs. This design is only available for straight-edged movable blades on the market. The slotted hole for securing the movable blade facilitates adjustment of the gap between the movable blade and the fixed blade. The blade is treated with a tungsten carbide coating, which enhances sharpness, reduces wear, and increases wear resistance, increasing blade durability by two to three times.

[0007] As an improvement, the straight edge sections are evenly provided with long holes.

[0008] As an improvement, the movable blade body is treated with a tungsten carbide coating. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] The following further describes specific embodiments of the present invention with reference to the accompanying drawings. Identical components are denoted by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "inward" and "outward" refer to directions toward or away from the geometric center of a particular component, respectively.

[0014] In order to make the contents of the present invention more clearly understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0015] like Figure 1 、 Figure 2As shown, a straight-blade bending movable knife includes: a movable knife body 1, the movable knife body 1 includes: an integrally formed straight-blade section 101, the straight-blade section 101 is integrally formed and connected to a bending section 102, a knife tip section 103 is provided at the bottom end of the bending section 102, the angle between the straight-blade section 101 and the bending section 102 is 152°, and the thickness angle of the knife tip section 103 is 21°.

[0016] like Figure 1 、 Figure 2 The straight blade section 101 is uniformly provided with long holes 104. The movable blade body 1 is treated with a tungsten carbide coating.

[0017] The blade of a straight-edged knife is used to reduce manufacturing costs and facilitate subsequent maintenance and grinding. The movable knife is bent at a certain angle at the appropriate position to increase the blade's strength. This angle also forces the cut material to change its accelerated material guide trajectory, causing the material to move in the desired direction and quickly enter the next mechanism for further processing. Furthermore, bending the movable knife relative to the uncut material can slow blade wear, thereby reducing the frequency of grinding, extending the life of the movable knife, and reducing subsequent use costs (this only applies to straight-edged movable knives on the market). The hole for fixing the movable knife is a long hole to facilitate adjustment of the gap between the movable knife and the fixed knife. The blade is treated with a tungsten carbide coating, which can improve the sharpness of the blade, reduce wear and increase wear resistance, making the blade's durability more than 2 to 3 times longer.

[0018] The above description is only a preferred embodiment of the present utility model patent and is not intended to limit the present utility model patent. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model patent shall be included in the scope of protection of the present utility model patent.
