Detailed Description
The invention will be further described with reference to the accompanying drawings and specific embodiments.
Example 1: as shown in figures 1-7, the disc-shaped multi-petal saw blade for cleaning tree barriers comprises a flat base disc 1 with a shape of petals distributed in central symmetry, a cutting edge 2 positioned in the rotating and advancing direction of the petals of the base disc 1 and sawteeth 3 positioned on the circumference of the radial outer side of the base disc 1, wherein the number of the petals of the base disc 1 is M, and M is more than or equal to 2.
Preferably, the saw teeth are divided into large teeth 301 and small teeth 302, and the small teeth 302 are located between the blade 2 and the large teeth 301 as a buffer structure.
Example 2: as shown in fig. 1, a disc-shaped multi-petal saw blade for removing obstacles has three configurations, namely a basic type, an enlarged working surface type and a multi-petal type. The configuration of the basic saw blade reduces the contact area with trees during working, reduces the frictional resistance on the surface of the saw blade, prevents blockage, and increases the functions of cutting, sawing and pushing the saw blade through the blade 2. Compared with the basic saw blade, the saw teeth 3 of the enlarged working surface type saw blade extend backwards along the petal rotation advancing direction of the base plate 2, and the length of the cutting saw is increased; the multi-petal type saw blade has more petals, and can provide more cuts with the blade 2 and the cutting surfaces with the saw teeth 3.
Example 3: as shown in fig. 2, the profile of the blade 2 is preferably a straight line, a broken line, a smooth curve or a combination of various line types, so as to meet different requirements of "cutting, sawing and pushing" under different environments.
Example 4: as shown in fig. 3, preferably, the cutting edge 2 is a single bevel cutting edge or a double bevel cutting edge, the single bevel cutting edge is distributed on the same surface or two surfaces of the base plate 1 alternately, and the cutting edge can be replaced according to the size of the working incision needed by the trunks with different thicknesses, so as to prevent the saw blade from being blocked.
Example 5: as shown in fig. 4, preferably, the center of the base plate 1 is provided with a slip-proof mounting fixing groove 4, the mounting fixing groove 4 is shaped to include a polygonal, elliptical, outer concave, inner convex opening in the center of the base plate 1, and the central surface of the base plate 1 is provided with an upper convex portion protruding upwards or a lower concave portion recessed downwards. The installation fixed slot 4 makes the saw bit dismouting simple and easy, and the security is high.
Example 6: as shown in fig. 5, it is preferable that the surface of the base plate 1 is provided with an expansion protrusion 5, and the expansion protrusion 5 has a slope that is lower in the front and higher in the back along the petal rotation direction of the base plate 1, or a slope that is lower in the outside and higher in the inside along the radial direction from the outside to the center of the base plate 1. The expansion bulge 5 increases the working notch space and has a certain expansion effect, so that the saw blade is easier to feed.
Example 7: as shown in fig. 6, it is preferable that the surface of the base plate 1 is provided with a convex tooth 6 having a cutting function. The convex teeth 6 increase the width of the cut of the saw blade during operation, avoid blockage and simultaneously increase the feasibility of multi-directional operation.
Example 8: as shown in fig. 7, the base plate 1 is preferably provided with uniformly distributed flutes 8, and the side teeth 7 are preferably attached to the side surfaces of the flutes 8 away from the petal rotation direction of the base plate 1 and higher than the surface of the base plate 1. When the saw bit cuts thick trunk, side tooth 7 provides the cutting force, avoids the trunk to the saw bit jamming phenomenon that the extrusion of basal disc 1 caused.
The above description is only an example of the specific embodiments of the present invention, and the scope of the present invention is not limited thereto. Those skilled in the art can easily find changes or substitutions within the technical scope of the present disclosure, which should be covered by the protection scope of the present invention.
