and a fastener 4 selectively connecting the connecting portion 21 and the annular cutter 11 or the annular cutter 12 so that the annular cutter 11 or the annular cutter 12 is fixed in the through groove 211. The fastening piece can be of a bolt-nut type structure, namely, the fastening piece is inserted into a through hole for fixing preset on the annular stripping knife or the annular stripping knife and a corresponding through hole for fixing preset on the connecting part, so that the annular stripping knife or the annular cutting knife is fixedly arranged in the through groove, and the annular stripping knife or the annular stripping knife is arranged outside the knife handle for operation. The connecting part can be of a U-shaped steel plate structure, namely, the cuboid plate structure is provided with a through groove to enable the section to be U-shaped, one of the annular stripping knife or the annular cutting knife is accommodated and fixed in the U-shaped groove, but in the mode, the two parts which are needed to be separated and independent are matched, and in the conversion use process of the annular stripping knife and the annular cutting knife, the parts of the fastening part are easy to lose, and the replacement is troublesome and the operation is inconvenient.
In the technical scheme, when the cutter body is in a straight line shape, the girdling cutter head and the girdling cutter head are respectively positioned at two ends of the cutter body, and when the cutter body is in a V-shaped structure, the girdling cutter head and the girdling cutter head are respectively positioned at two end points on the upper part of the V-shaped structure. When one of the annular stripping knife and the annular cutting knife is positioned in the through groove and fixed, the other one can be used for operation, so that the other knife cannot be scratched by a planter during use, and the safety is higher during operation.
In another technical scheme, the girdling and girdling integrated knife is characterized in that the connecting part 21 is cylindrical, the length of the through groove 211 is smaller than that of the connecting part 21, and an external thread extending from one end of the connecting part 21 to a position below the through groove 211 is arranged outside the connecting part 21; the screw thread outside the connecting part can extend to one end of the connecting opening or can extend to a proper position to meet the screw thread fixation of the annular stripping knife or the annular cutting knife;
the parts of the cutter body 1 except the annular cutter head 111 and the annular cutter head 121 are provided with external threads 13 which are the same as the outside of the connecting part 21 on the left side and the right side of the linear structure or the inner side and the outer side of the V-shaped structure, as shown in the partial schematic diagram of the annular cutter in fig. 4, it should be noted that, as the external threads on the annular cutter or the annular cutter need to be matched with the internal threads on the fastening piece, the annular cutter and the annular cutter are described, and the part provided with the external threads is provided with an arc surface structure matched with the inner wall of the circular ring structure of the fastening piece, such as the structure of the annular cutter 11 in the sectional view shown in fig. 7;
the fastener 4 is of a circular ring structure, an inner side of the fastener is provided with an inner thread matched with the outer thread, and the widths of the girdling knife 11 and the girdling knife 12 are set as follows: when the annular cutter 11 is fixed in the through groove 211, the fastening member 4 is screwed with the connecting portion 21 and the annular cutter 11, as shown in fig. 6 and 7; when the cutting ring 12 is fixed in the through groove 211, the fastening member 4 is screwed with the connecting portion 21 and the cutting ring 12. The width of the annular stripping knife or the annular cutting knife is limited, so that the annular stripping knife or the annular cutting knife can be connected with the screw thread of the fastener when being accommodated in the through groove.
In this technical scheme, thereby fastener is through with connecting portion, ring cutter or ring broach threaded connection fixed ring cutter or ring broach one of them, this fastener is along the outside screw thread rotation of connecting portion's length direction, when change ring cutting sword (ring broach) for ring broach (ring cutting sword), the fastener needs the screw thread to the position below the connecting portion link up the groove to make ring cutting sword or ring broach can accomodate smoothly in the link up the groove, then at the screw thread rotation in order to lock ring broach or ring cutting sword in the link up the inslot to connecting portion U-shaped opening direction.
In another technical scheme, the girdling and girdling integrated knife comprises an included angle alpha between the girdling knife 11 and the girdling knife 12 is 120 degrees, and the connecting part 21 and the knife handle 2 are on the same straight line. In the technical scheme, when one of the annular stripping knife and the annular cutting knife is fixedly arranged in the through groove, the other annular stripping knife and the knife handle are 120 degrees, and under the scheme, the annular stripping knife or the annular cutting knife is more convenient to use.
In another technical scheme, as shown in fig. 5, the girdling cutter head 111 includes a girdling edge penetrating from the inner side to the outer side of the V-shaped structure, and a girdling edge forming the girdling edge, the inner opening of the girdling edge is concave inward to form an arc shape, and the projection length of the inner opening of the girdling edge on the inner side surface of the girdling edge is smaller than the projection length of the outer opening of the girdling edge on the inner side surface of the girdling edge. The width of the girdling knife edge is set to be the width required by actual girdling, and is related to the thickness of the girdling knife head.
In the technical scheme, the girdling knife edge is composed of two thin parallel side faces, a thin knife edge face positioned between the two side faces and a back face acted by the girdling knife body, wherein the width of the girdling knife edge, namely the width of the knife edge face, is determined by the two side faces, namely the knife edge face is an actual girdling action edge, namely a knife edge line in girdling, one end of the girdling knife opening positioned at the inner side of the V-shaped structure is a girdling knife edge action end, also is a feeding end, one end discharge end at the outer side of the V-shaped structure, namely bark cut by the girdling knife head stretches out from the inner side of the girdling knife opening to the outer side, and the girdling knife edge is not easy to block due to the fact that the length of an outer side outlet of the girdling knife edge is larger than that of an inner side knife edge.
In another embodiment, as shown in fig. 5, the portion of the girdling cutter head 111 located outside the V-shaped structure is arc-shaped. The arc-shaped discharging end opening is larger, the bark is more easily discharged, and the arc-shaped annular stripping cutter head is more attractive.
In another embodiment, as shown in fig. 5, the girdling cutter head 121 includes an arc-shaped blade that is recessed inward in the V-shaped structure, and the thickness of the arc-shaped blade is gradually thinned along the direction away from the first through hole, so that the end of the arc-shaped blade away from the first through hole is a tip structure, i.e. a "cutting edge" during girdling. The curved edge meets the need for girdling because the edge needed for girdling is very thin, resembling a sickle point.
In another technical scheme, as shown in fig. 3, the limiting piece 3 is detachably connected with the connecting portion 21 and the cutter body 1. The limiting piece can be of a structure similar to a screw and a nut, the screw penetrates through the second through hole of the connecting part and the first through hole of the cutter body, and the nut is fixed through threaded connection, so that the cutter body is limited between the through grooves of the connecting part.
Although embodiments of the present invention have been disclosed above, it is not limited to the details and embodiments shown and described, it is well suited to various fields of use for which the invention would be readily apparent to those skilled in the art, and accordingly, the invention is not limited to the specific details and illustrations shown and described herein, without departing from the general concepts defined in the claims and their equivalents.
