Description
The utility model relates to the cutting tool that a kind of fruit growing is used, particularly a planting fruit-trees girdling device.
People explore the culture technique of a series of raising output of the fruit tree and quality in long-term fruit production practices; fruit tree girdling technology is exactly wherein a kind of; it removes one section bast zone by carry out girdling on fruit tree or branch; the nutriment not tree body below the girdling position and root conveying in the short time that fruit tree is produced through photosynthesis; carry to fruit and concentrate; to increase the volume and the nutrition of fruit, play the effect of flower and fruit protecting, reach the purpose that increases the yield of fruit with quality.Facts have proved that this technology can increase the yield of fruit more than 10%.Still the specialist tools of not having at present the fruit tree girdling, mostly people are to cut two annular incision with saw blade or blade along trunk or branch hoop, the bark bast zone between two annular incision are peeled off again.Carry out girdling with saw blade or blade and mainly have following defective: the one, inefficiency, the 2nd, girdling is of poor quality, and the degree of depth and width are difficult to reach specification requirement, often cause intrinsic layer also wide by girdling or girdling, influence the fruit tree normal growth, even dead.
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of work efficiency height is provided, does not injure layer of wood, girdling kerf width uniformity and neat fruit tree girdling device.
The purpose of this utility model realizes by following proposal:
A design left side, in, right three arc braces, in arc brace two ends respectively with a left side, right arc brace one end is hinged by latching, its other end becomes annular stent by the fastener clamping, a left side, right arc brace abutting end all laterally offers oblong openings, two arc sheets form one handle displacement groove mutually after touch, each arc brace inboard is an arc chute, its inboard, two ends is provided with limiting plate, be provided with the middle part in the chute and be the arc shaped slider of groove, three slide blocks touch mutually and constitute a displacement annulus, arc shaped slider groove one end and arcuate claws one end are hinged by latching, the wedge that the arcuate claws other end is provided with interface and blade or is provided with blade plugs, the arc shaped slider groove other end be provided with the arc brace on affixed push rod, left or right arc brace and one handle are affixed, the arc shaped slider of another arc brace inboard and another handle Joint.
Said fastener is clasp and retaining ring groove or hasp and hasp post.
Arcuate claws and arc shaped slider connecting portion are provided with a shell fragment or top spring, so that arcuate claws can be repositioned in the groove of slide block after the girdling.
Push rod also can be designed to screw rod, in order to regulating the push rod height.
Said blade can be double-deck blade, and three double-deck blades also can be single blades on same horizontal line, and three single blades should be on same horizontal line, and potential difference is between 1-2mm.
The utility model mainly is to link to each other with three arc braces to constitute an annular stent, three arc shaped sliders in its inboard chute, constitute an annular sliding component again, when one was subjected to displacement with the affixed slide block of handle, other two slide blocks also were subjected to displacement simultaneously, contact mutually with the arc back of the body of arcuate claws by push rod, arcuate claws one end that blade is installed is stretched out to the inside, so that blade touches mutually with bark, and, insert in order to blade in the bast zone of bark by the kneading of two handles.
From above-mentioned situation as can be known, the purpose of this utility model can realize.During use, at first open fastener, the annular stent that arc connector is constituted opens and is placed on tree bar or the branch, buckle fastener, make circular support fixing in aggregates, mediate two handles again, because a handle is affixed with an arc brace, the arc shaped slider Joint of another and another arc brace inboard makes the arc shaped slider displacement, and by push rod the double-deck blade in arcuate claws end is inserted in the bast zone of bark, by handle the girdling device is rotated 120 ° (single blade should change 360 °), make the bast girdling of fruit tree bar or branch, peel off bast zone between two otch again, and finish the girdling process.
Through actual tests, carry out the fruit tree girdling with the utility model and can improve work efficiency 20-30 doubly, it can not damage layer of wood, otch is neat, width is consistent, with the fruit tree of this girdling device girdling 20-30% that increases the yield of fruit, fruit quality has clear improvement, and can reach the 70-80 gram as the Chinese date grain is heavy.
Accompanying drawing and drawing are described as follows.
Accompanying drawing is the utility model structure cut-away view.
In conjunction with the embodiments the utility model is further described with reference to the accompanying drawings below:
As shown in drawings, three arc braces in design left, center, right 1,9,11, middle part, middle arc brace 9 two ends laterally is provided with groove, and be provided with latching hole 2, it is hinged that itself and left and right arc brace 1,11 1 ends middle part is provided with the boss in hole, arc brace abutting end middle part in the left and right sides all laterally is provided with oblong openings 14, and the two links to each other and constitutes groove, so that slide within it with the handle of arc shaped slider 5 Joints.About two arc braces by clasp 15 and retaining ring groove 13 or hasp and the clamping mutually of hasp post respectively provided thereon, constitute an annular stent, present embodiment is selected the former for use.Three arc brace inboards are arc chute 4, be provided with arc shaped slider 5 in it, three arc shaped sliders touch mutually and constitute annular displacement ring, for its arc slide block is not skidded off, each inboard, arc chute two ends is equipped with limiting plate 3, the arc shaped slider two ends are through in it, the width of limiting plate does not skid off when guaranteeing the arc shaped slider displacement, said arc shaped slider middle part laterally is provided with a groove, be provided with arcuate claws 8 in the groove, arcuate claws one end is hinged by groove one end of latching and arc shaped slider, can establish a shell fragment or top spring at connecting portion in case of necessity, guarantee to use the timely return of back blade, arcuate claws other end inboard is provided with interface and blade 6 or has wedge 7 grafting of blade, and what present embodiment was selected for use is the wedge that has double-deck blade, two blade spaces are from designing as required, generally should not surpass 2mm, be no less than 1mm, present embodiment is selected 1.6mm for use.Double-deck blade on the different arcuate claws all should be on same horizontal level, and neat to guarantee the girdling otch, blade also can be designed to the individual layer blade certainly, and each individual layer blade should be on same horizontal line, and the potential difference sum is between 1-2mm.Be inserted with the push rod 10 that is fixed on the arc brace in the arc shaped slider groove of arcuate claws blade end, the push rod end is the semicircle sphere, so that push up mutually with the arc back of the body of arcuate claws during the arc shaped slider displacement, and blade is stretched out to fruit tree girdling device inboard, push rod also can be designed to screw rod, capable being threaded of screw that it is provided with the arc brace is so that can in time adjust the push rod height as required.Left and right arc brace or its inboard arc shaped slider and handle 12 are affixed, and present embodiment selects for use right arc brace and right handles affixed, and the arc shaped slider and the capable screw thread of left handle of left arc brace inboard are affixed.
