Description

Technical Field

[0001] This utility model provides a shrub-clearing mechanical blade head, and particularly relates to a shrub-clearing mechanical blade head that is easy to assemble and disassemble. Background Technology

[0002] The shrub-clearing machine's blade head is the core actuator installed at the front end of the shrub-clearing machine. Its main function is to cut and prune shrub branches, vines, etc. through high-speed rotation or reciprocating motion to achieve shrub clearing operations in scenarios such as landscaping and road maintenance. Its structural design directly affects the clearing efficiency, ease of disassembly and assembly, and equipment compatibility.

[0003] Existing shrub-clearing machine blades typically consist of a blade body, the top of which is often flat or non-standard inclined, the middle has non-standard threaded holes or snap-fit ​​structures, and the bottom has a simple cutting edge. However, this type of structure has obvious shortcomings: First, the connection structure lacks standard specifications, resulting in time-consuming disassembly and assembly with the drive components and low positioning accuracy; second, the top inclined surface angle is not standardized, the lateral width is not adapted, the bottom cutting edge is often an asymmetrical structure, and the side and top views are not optimized, resulting in an unreasonable feed angle, low cutting efficiency, and poor overall size compatibility with equipment, failing to meet the needs of efficient and convenient shrub clearing.

[0022] 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.

[0023] It should be noted that the terms "vertical," "horizontal," "up," "down," "left," "right," and similar expressions used in this article are for illustrative purposes only and do not represent the only possible implementation.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein in the description of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention; the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0025] like Figure 1 and Figure 2 As shown, a shrub-clearing mechanical blade head that is easy to assemble and disassemble includes a blade head body 1. The top inclined upper surface of the blade head body 1 has a threaded mounting hole 2 of 3 / 4-16UNF specification that runs vertically through the middle. The lower end of the threaded mounting hole 2 is coaxially connected to an arc-shaped boss 3 with a diameter of φ32 and a height of 14.4. The overall height of the blade head body 1 is 63.3. Through the standard specifications of the threaded hole, the coaxial adaptation of the boss, and the overall height design, the mechanical blade head and the drive component can be quickly assembled and disassembled and stably connected.

[0026] In this implementation scheme, the cutter head body 1 is an integral load-bearing structure. The middle part of its inclined upper surface is connected to the threaded mounting hole 2. The lower end of the threaded mounting hole 2 is coaxially fixedly connected to the arc-shaped boss 3. The arc-shaped boss 3 is located on one side of the bottom of the cutter head body 1. The overall height of the cutter head body 1 is 63.3 mm to adapt to the installation space. During implementation, the threaded mounting hole 2 of 3 / 4-16UNF specification is compatible with universal connectors to achieve quick disassembly and assembly. The arc-shaped boss 3 ensures installation accuracy through coaxial setting. The overall height ensures that it matches the structure of the equipment, which solves the problems of cumbersome disassembly and assembly, inaccurate positioning and poor adaptability of existing cutter heads.

[0027] like Figure 2 and Figure 3As shown, the top inclined surface of the cutter head body 1 has an included angle of 10°, a transverse width of 93.2, and a longitudinal width of 72.4 on one side; the bottom is provided with symmetrically distributed V-shaped cutting edges 6, the side profile is an outwardly expanding arc shape, and the top view cross section is a symmetrical structure 7 that is "narrow in the middle and wide at both ends". Through the adaptation of the inclined surface angle and size, as well as the design of the cutting edge and profile, the efficiency of shrub cutting and the structural adaptability are improved.

[0028] In this embodiment, the inclined upper surface of the cutter head body 1 is an integral structure with the body. The 10° included angle and 93.2 mm lateral width form a reasonable feed guide surface, and the 72.4 mm longitudinal width on one side is adapted to the overall structure. The symmetrical V-shaped cutting edge 6 at the bottom is connected to the bottom edge of the body. The outwardly expanding arc-shaped contour on the side and the symmetrical structure 7 with "narrow in the middle and wide at both ends" when viewed from above are structural features of the cutter head body 1 itself. In implementation, the 10° inclined surface facilitates the entry of shrubs into the cutting area, the V-shaped cutting edge 6 enhances the cutting force and uniformity through symmetrical distribution, and the outwardly expanding arc-shaped side and the specific top-view structure 7 improve the stability of the cutter head during operation and its adaptability to different shrub shapes, effectively solving the problems of low cutting efficiency and insufficient structural adaptability of existing cutter heads.

[0029] When in use, this device needs to be used in conjunction with the existing bush-clearing mechanical drive shaft, drive motor and protective cover. The cutter head body 1 can be made of 40Cr alloy structural steel. This material has high strength and wear resistance, which can meet the requirements of the cutter head cutting performance and service life in the bush-clearing process. The V-shaped cutting edge 6 can be further improved in hardness through quenching treatment to ensure the durability of its cutting effect.

[0030] Specifically, during installation, first clean the end of the drive shaft of the shrub-clearing machine, align it with the threaded mounting hole 2 in the middle of the cutter head body 1, and rotate the cutter head clockwise until the arc-shaped boss 3 fits against the end of the drive shaft to complete the fixation; before use, check whether the distance between the protective cover and the cutter head body 1 is within the safe range, start the drive motor, and drive the drive shaft to rotate, which in turn drives the cutter head body 1 to rotate at high speed. During operation, align the V-shaped cutting edge 6 at the bottom of the cutter head with the shrub, and use the 10° inclined upper surface at the top to guide the shrub into the cutting area. The side outward arc shape and the symmetrical structure 7 of "narrow in the middle and wide at both ends" when viewed from above maintain the stability of the operation. During the cutting process, the position of the cutter head in contact with the shrub can be changed by adjusting the angle of the robotic arm; after use, turn off the drive motor, wait for the cutter head to stop rotating completely, and rotate the cutter head body 1 counterclockwise to remove it from the drive shaft, clean the residual debris on the cutting edge, and store it.

[0031] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be determined by the claims.
