Description

Working group type mowing saw blade

Technical Field

The utility model relates to a saw bit technical field specifically is a work group type saw bit of mowing.

Background

Saw blades are a general term for thin circular cutters used to cut solid materials. The saw blade can be divided into: a diamond saw blade for stone cutting; a high-speed steel saw blade (without a cemented carbide bit) for cutting metal materials; the hard alloy saw blade is used for cutting solid wood, furniture, artificial boards, aluminum alloy, aluminum profiles, radiators, plastics, plastic steel and the like. The hard alloy saw blade comprises a plurality of parameters such as the type of an alloy cutter head, the material of a matrix, the diameter, the number of teeth, the thickness, the tooth shape, the angle, the aperture and the like, and the parameters determine the processing capacity and the cutting performance of the saw blade. When the saw blade is selected, the saw blade needs to be correctly selected according to the type and the thickness of a sawing material, the sawing speed, the sawing direction, the feeding speed and the sawing path width.

When using, the existing saw blade has no cutting edge in the knife valley between the adjacent knife heads, when the plant is not clamped between the knife valleys by the knife head cutting card, certain resistance can be generated to influence the operation of the saw blade, the working efficiency of the saw blade is reduced, and even the saw blade can stop rotating due to strong resistance.

Therefore, the working group type mowing saw blade is provided for solving the problems in the prior art, so that the cutting edge is added in the knife valley, plants are cut, the running resistance of the saw blade is reduced, and the cutting efficiency is ensured.

Preferably, the thickness of the end of the blade is slightly greater than the thickness of the saw blade body.

Preferably, one side of the end part of the cutter head, which is far away from the cutting edge, is provided with a boss, and the cutting edge of the cutter head extends to the boss.

Preferably, the middle of the saw blade main body is provided with a decorative hole positioned on the outer side of the axle center hole, and the plurality of groups of axle center holes are arranged on the saw blade main body in an array mode.

Preferably, one end of the knife valley extends to the middle position of the cutting edge of the cutter head, and the thicknesses of the knife valley and the cutter head are gradually reduced from the saw blade main body outwards.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model discloses saw bit main part during operation, the tool bit that sets up in the middle of the knife tackle in succession is used for cooperating the plant that the cutting needs pruned, and the sword millet of sharpening is used for the plant that the cutting tool bit failed to cut, reduces the resistance that the plant card of omitting the cutting brought for the saw bit operation between the tool bit, guarantees that the saw bit can the steady operation, improves saw bit work efficiency.
