Description
Technical Field
The utility model belongs to palm trees petiole field of pruning, specifically speaking especially relates to a take convex curved knife that saw cuts of arc sawtooth.
Background
The existing pruning machine tool for branches of high-branch trees generally comprises a high-branch saw and a high-branch sickle, wherein the high-branch saw is low in cutting efficiency, a chain rotating at a high speed is easy to damage a trunk of the tree, particularly a palm trunk is easy to damage, the palm trunk is damaged, the fruiting rate of the palm trunk is influenced, and the trunk is seriously and directly dead. Therefore, the high-branch sickle appears, but the old high-branch sickle has the defects that the engine guides the sickle to do reciprocating motion when the sickle is used for cutting, so that the sickle jumps up and down on the cut branches, the effective cutting cannot be formed, the operation efficiency is low, the labor intensity of workers cannot be greatly reduced, and the popularization and the application are difficult to achieve greatly.
Disclosure of Invention
The to-be-solved technical problem of the utility model is: overcome prior art's not enough, provide a take arc saw cutting curved bar of arc sawtooth, it cuts through the orthodrome saw cutting tooth, easily wears the crust, prevents to skid, cuts labour saving and time saving, and the atress is even, fatigue resistance is high, has improved life greatly.
The arc-shaped sawing curved knife with the arc-shaped sawteeth comprises an arc-shaped knife body, wherein an arc-shaped cutting edge is arranged on the inner side of the knife body, a cutting inlet end and a mounting end are respectively arranged on two sides of the arc-shaped cutting edge, the cutting inlet end and the mounting end are respectively arranged in the tangential direction of the arc-shaped cutting edge, large arc-shaped sawing teeth which are uniformly distributed are arranged on the arc-shaped cutting edge, and the arc angle a of the large arc-shaped sawing teeth is 250-280 degrees.
Preferably, the arc of the circular arc blade is a quarter circle.
Preferably, the center of each large circular arc sawtooth is located on the same circle E.
Preferably, the circle center a of the outer circular arc of the cutter body, the circle centers B and C of the upper and lower circular arcs of the circular arc-shaped cutting edge and the circle center D of the circle E are located on a straight line.
Compared with the prior art, the beneficial effects of the utility model are that:
1. the cutter body is in the shape of an arc-shaped bent cutter, the arc is in a quarter-circle design, and the mounting end and the cutting inlet end of the cutter body are arranged in the tangential direction of the circle, so that the cutting-in and cutting-out of the cutting edge can effectively do work;
2. the arc-shaped cutting edge is additionally provided with the large arc saw cutting teeth with 250 and 280 radians, the sharp angle of the arc is sharp, so that the hard skin can be easily broken, the sliding is prevented, and the cutting is very labor-saving and easy;
3. the circle center A of the outer arc of the cutter body, the circle centers B of the upper and lower arcs of the arc-shaped cutting edge, the circle center C and the circle center D of the circle E are positioned on the same straight line, so that the cutter body is uniformly stressed, the fatigue resistance is high, and the service life is prolonged.
Drawings
Fig. 1 is a schematic structural view of the present invention;
FIG. 2 is an enlarged view of a portion A of FIG. 1;
fig. 3 is a reference diagram of the usage status of the present invention.
In the figure, 1, a tool body; 2. a circular arc blade; 3. sawing and cutting teeth with a large circular arc; 4. cutting the inlet end; 5. an installation end; 6. mounting holes; 7. a circle center A; 8. a circle center B; 9. a circle center C; 10. and a circle center D.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings:
as shown in fig. 1, the circular arc sawing curved knife with the arc-shaped sawteeth comprises a circular arc-shaped knife body 1, a circular arc-shaped cutting edge 2 is arranged on the inner side of the knife body 1, a cutting inlet end 4 and a mounting end 5 are respectively arranged on two sides of the circular arc-shaped cutting edge 2, the cutting inlet end 4 and the mounting end 5 are respectively arranged in the tangential direction of the circular arc-shaped cutting edge 2, and large circular arc sawing teeth 3 which are uniformly distributed are arranged on the circular arc-shaped cutting edge 2; the arc of the arc-shaped blade 2 is a quarter circle; the center of each large circular arc sawtooth 3 is positioned on the same circle E.
The circle center A7 of the outer circular arc of the cutter body 1, the circle centers B8 of the upper and lower circular arcs of the circular arc-shaped cutting edge 2, the circle center C9 and the circle center D10 of the circle E are positioned on the same straight line.
As shown in fig. 2, the arc angle a of the large arc sawtooth 3 is 250-280 °.
The utility model discloses when the preparation, set up the quantity of major arc sawtooth 3 as required, major arc sawtooth 3 is ten in this embodiment.
As shown in figure 3, when in use, the mounting end 5 is provided with a mounting hole 6, the cutter body 1 is connected with a mounting seat through the mounting hole 6, and the mounting seat is connected with an engine gear box through a connecting rod. During operation, under the effect of engine, cutter body 1 moves along with reciprocating motion's connecting rod, cuts into along cutter body 1's tangential direction, because cutter body 1 can up-and-down reciprocating motion, big circular arc saw cuts tooth 3 and takes place to saw cut the motion on sharp convex cutting edge 2, and the hard crust of palm petiole is worn at first to several first teeth of ten big circular arc saw cuts tooth 3, and secondly is that softer petiole meat is difficult to block sharp convex cutting edge 2, along with cutter body 1 reciprocating motion, cuts off stout petioles at one stroke, and efficiency is high.
