Abstract
Description
Technical Field
[0001] The invention relates to the technical field of cutter disc structures, and in particular to a mowing cutter disc structure. Background Art
[0002] Application number: TW110209516, authorization publication number: TWM629673U, it is mainly equipped with an anti-collision circular cutter disc, at least one tool, at least one upper fixing part and at least one lower fixing part. Although the tool can be rotatably fixed in the anti-collision circular cutter disc by the upper fixing part and the lower fixing part, when the tool hits a foreign object, it will rebound into the anti-collision circular cutter disc, so that the tool will not be damaged by colliding with the foreign object. Although the patent can rotatably set the tool in the anti-collision circular cutter disc, it is impossible to quickly replace the tool when it is damaged, and it is easy to cause the upper fixing part and the lower fixing part to loosen after long-term use, causing the tool to fly out, so there is a high risk. Therefore, it is necessary to design a lawn mowing cutter disc structure to solve the above problems. Summary of the Invention
[0003] In order to solve the above problems, the present invention provides a lawn mowing blade structure, including a blade disc, the blade disc including an upper disc seat and a lower disc seat, the upper disc seat being provided with at least one first hole, the upper disc seat being provided with at least one convex portion, the convex portion being a tough ring body, the convex portion being provided on the periphery of the first hole, the lower disc seat being provided with at least one second hole, the tool being provided between the upper disc seat and the lower disc seat, the tool being provided with a third hole, the connecting member being passed through the second hole, the third hole and the first hole, the connecting member being provided with a fourth hole, the connecting member being provided with a fixing member, the fixing member being passed through the fourth hole, and the present invention being able to realize the function of quickly replacing the tool, and due to the centrifugal force, the fixing member being limited by the convex portion to prevent the tool from falling off during high-speed operation.
[0004] A further improvement of the present invention is that: a plurality of the protrusions are each provided with a notch, and a plurality of the notches are directed toward the center of the cutter disc.
[0005] A further improvement of the present invention is that the diameter of the fixing member is larger than the diameter of the notch.
[0006] A further improvement of the present invention is that a hollow structure is formed between the upper disc seat and the lower disc seat, and the tool can rotate 360° in the hollow structure.
[0007] A further improvement of the present invention is that the first hole is arranged at the center of the convex portion.
[0008] A further improvement of the present invention is that the tool is in the shape of a hook and has a structure that is narrow at the bottom and wide at the top. Such a structural setting can make the tool more wear-resistant and durable, and reduce the possibility of the tool breaking during use.
[0009] A further improvement of the present invention is that the connecting piece is a cylindrical structure.
[0010] Beneficial effects of the present invention:
[0011] The fixing part of the present invention passes through the notch and enters the fourth hole, so that the fixing part can rotate arbitrarily in the convex part when the cutter disc is in operation. When the cutter is damaged and needs to be replaced, the cutter can be quickly replaced by simply removing the fixing part from the notch. The fixing part passes through the convex part and enters the fourth hole, so that the cutter can be quickly replaced. Due to the centrifugal force, the fixing part is restricted by the convex part to prevent the cutter from falling off during operation.

[0020] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.
[0021] The present invention relates to Figure 1 、 Figure 2 As shown, the present invention relates to a mowing disc structure, comprising a disc 1, wherein the disc 1 is provided with an upper disc seat 11 and a lower disc seat 12, wherein the upper disc seat 11 is provided with three first holes 111 arranged at equal distances, and the three first holes 111 are surrounded by convex portions 112, wherein the convex portions 112 are tough ring bodies, and the lower disc seat 12 is provided with a plurality of second holes 121.
[0022] The tool 2 is arranged between the upper disc seat 11 and the lower disc seat 12, and the tool 2 is provided with a third hole 21; the tool 2 is connected between the upper disc seat 11 and the lower disc seat 12 through a connecting member 3, and the connecting member 3 is provided through the second hole 121, the third hole 21 and the first hole 111, so that the tool 2 can be rotatably fixed between the upper disc seat 11 and the lower disc seat 12, and the connecting member 3 is provided with a fourth hole 31, and the connecting member 3 is provided with a fixing member 32, and the fixing member 32 is provided through the fourth hole 31.
[0023] The protrusion 112 is tough, so when the fixing member 32 is pressed downward by human power, the protrusion 112 can be deformed so that the fixing member 32 can pass through the fourth hole 31; a notch 1121 can also be provided on the protrusion 112, wherein the diameter d1 of the fixing member 32 is larger than the diameter d2 of the notch 1121 (such as Figure 3 As shown in the figure, since the protrusion 112 has toughness, the fixing member 32 can penetrate the fourth hole 31 by squeezing the notch 1121, thereby allowing the fixing member 32 to pass through. After penetration, since the diameter d1 of the fixing member 32 is larger than the diameter d2 of the notch 1121, the fixing member 32 will not fall out of the notch 1121 except by human force. Such a structural setting makes it safer, more convenient and labor-saving for users to use.
[0024] Please refer to Figure 5 As shown, there is a hollow structure between the upper disc seat 11 and the lower disc seat 12, in which the tool 2 can rotate 360 degrees. When the cutter disc 1 is in operation, if the tool 2 hits a stone or foreign object, the tool 2 will rotate into the hollow space between the upper disc seat 11 and the lower disc seat 12 to prevent the tool 2 from being damaged or broken. Please refer to Figure 3 、 Figure 4As shown, the connecting member 3 is rotatably fixed in the first hole 111, the second hole 121 and the third hole 21, so when the fixing member 32 is locked and operates in the cutter disc 1, the connecting member 3 can rotate freely. At the same time, since the diameter d1 of the fixing member 32 is larger than the diameter d2 of the notch 1121, the fixing member 32 will not fall out of the notch 1121, and the cutter disc 1 will not cause the tool 2 to fly out due to the loosening of the fixing member 32 during operation over time, which can improve the safety of the present invention as a whole.
[0025] The connecting member 3 is rotatably fixed in the first hole 111, the second hole 121 and the third hole 21. The upper disc seat 11 is provided with a protrusion 112. The fixing member 32 penetrates into the fourth hole 31 through the notch 1121 of the protrusion 112, so that the fixing member 32 can rotate arbitrarily in the protrusion 112 when the cutter disc 1 is in operation. When the cutter 2 is damaged and needs to be replaced, the cutter 2 can be quickly replaced by simply removing the fixing member 32 from the notch 1121.
