Abstract

The utility model relates to a ring cutting device which is used for the ring cutting of fruit trees. The utility model is composed of a knife frame, and two cutting knives. Each cutting knife is composed of a knife blade and a knife holder which is perpendicular to the knife blade. Two cutting knives are arranged on the knife frame through the knife holders and matched connecting holes on the knife frame. One of the cutting knives or the two cutting knives are sliding cutting knives, and adjusting screws are arranged between the sliding cutting knives and the matched connecting holes on the knife frame. The space of the two knife blades is adjusted through pushing and pulling sliding knife holders, and the space of the two knife blades is fixed through screwing the adjusting screws. The operation of the existing ring cutting device is inconvenient in use, but the operation of the utility model is convenient.

Description

Ring cutting device

The utility model belongs to a kind of pruning fruit tree instrument, particularly a kind of girdling device that is used for the fruit tree girdling.

At present, the girdling device of Chu Shouing is fixed on two blades on the knife rest by screw on the market, and the spacing of two blades is regulated by plus-minus pad method, comparatively inconvenience during use.

The purpose of this utility model provides a kind of convenient girdling device that uses.

The purpose of this utility model is achieved in that the girdling device is made of knife rest and two cutteves, and cutter constitutes by blade with perpendicular to the handle of a knife of blade.Two handle of a knifes are contained in two blade both sides by the connecting hole with knife rest coupling respectively, and in the connecting hole of at least two handle of a knife one and knife rest coupling, every group has one and handle of a knife elongated hole forward at least; Perhaps two handle of a knifes are overlapping is contained on the knife rest, and in the connecting hole of two handle of a knifes and knife rest common match, every group on a handle of a knife is and handle of a knife elongated hole forward at least.In the connecting hole that is complementary that every group has an elongated hole, at least one set screw that is assembled with.

At least one set screw can be at the knife rest another side relative with cutter, and the maximum rotating diameter of nut or bolt and the ratio of minimum rotating diameter are greater than 2:1.

Use the utility model to carry out the fruit tree girdling, solved the awkward problem of current fruit tree girdling instrument.

Fig. 1 is the schematic diagram that the utility model handle of a knife is loaded on the blade both sides;

Fig. 2 is the overlapping schematic diagram that is loaded on the knife rest of the utility model handle of a knife.

Below in conjunction with accompanying drawing the utility model is done to describe in detail.

The girdling device is made up of knife rest (1) cutter (2) and cutter (3), and cutter (2) constitutes by blade (4) with perpendicular to the handle of a knife (5) of blade (4), and cutter (3) constitutes by blade (6) with perpendicular to the handle of a knife (7) of blade (6).

Each has the some groups of connecting holes that mate with knife rest handle of a knife (5) and handle of a knife (7), cutter (2), cutter (3) are contained in blade (4) and blade (6) both sides by connecting hole with handle of a knife (5), handle of a knife (7), in the connecting hole of two handle of a knife one and knife rest coupling, every group has one or all be and handle of a knife elongated hole (8) forward on knife rest or handle of a knife, this handle of a knife is the slip handle of a knife, its cutter is the slip cutter, and another cutter is fixing cutter.In every group of connecting hole of another handle of a knife and knife rest coupling, but also one or all be elongated hole, and its cutter one is as the slip cutter, to adjust the position of two blades on knife rest, the one, fixation is as fixing cutter in use, so that two cutter reversing of position in case of necessity increase the service life.

Handle of a knife (5), handle of a knife (7) also can overlappingly be contained on the knife rest, and promptly wherein a handle of a knife is contained between knife rest and another handle of a knife, and the connecting hole of two handle of a knife common match is arranged on the knife rest (1).In the connecting hole of common match, every group on a handle of a knife is and handle of a knife elongated hole (8) forward at least, and this cutter is as the slip cutter, and another cutter conduct is cutter fixedly.If on another handle of a knife or the knife rest also be elongated hole, two cutteves promptly all become the slip cutter.

For the slip cutter not only can be fixed but also can slide, at least one set screw (9) that is assembled with is arranged in the connecting hole that is complementary of elongated hole in each group.

In order to omit other aid (as spanner or screwdriver etc.) when regulating two blade spaces, at least one set screw can be at the knife rest another side relative with cutter, and the maximum rotating diameter of bolt or nut and the ratio of minimum rotating diameter are greater than 2:1.This nut or bolt be butterfly preferably.

If have only one group of connecting hole that is complementary on each cutter and the knife rest, can be in handle of a knife one side with knife rest (1) folding one anti-rotation shelves (10); Also can open a sliding tray on knife rest, handle of a knife is placed in the sliding tray, excessive handle of a knife rotates to prevent to exert oneself when the thick limb of girdling.

Skid when preventing girdling, it is curved knife rest to be rolled over a spill to the cutter direction along handle of a knife, so that the girdling device is stuck on the limb.

In order accurately to regulate the girdling width, on the slip handle of a knife, length mark is arranged.

Have blade on one side or on the angle at a knife rest or a handle of a knife, so that increase the peeling function of girdling device.

During girdling, according to required girdling width, push-and-pull slip handle of a knife is adjusted two blade spaces by length mark, screws set screw (9), with girdling device two alignment blade limbs, firmly rotates a circle around limb, as the need band girdle, with blade bark is chosen separated branch and does and to get final product.

Claims

1, a kind of girdling device that is used for the fruit tree girdling is made up of knife rest (1), cutter (2) and cutter (3), it is characterized in that:

Cutter constitutes by blade with perpendicular to the handle of a knife of blade; Two handle of a knifes are contained in two blade both sides by the connecting hole with the knife rest coupling respectively, in the connecting hole of at least two handle of a knife one and knife rest coupling, every group have at least one with handle of a knife elongated hole (8) forward, perhaps two handle of a knifes are overlapping is contained on the knife rest, in the connecting hole of two handle of a knifes and knife rest common match, every group on a handle of a knife is and handle of a knife elongated hole forward at least; In the connecting hole that is complementary that every group has an elongated hole (8), at least one set screw (9) that is assembled with.

2, girdling device according to claim 1 is characterized in that: have a set screw at least at the knife rest another side relative with cutter, the maximum rotating diameter of nut or bolt and the ratio of minimum rotating diameter are greater than 2:1.
