Abstract

The utility model relates to a ring peeling apparatus, which is composed of a handle (20) and a cutter frame (19). The cutter frame (19) comprises a fixed cutter frame (7), a movable cutter frame (9), an upper connecting arm (10), and a lower connecting arm (11). The upper end and the lower end of the movable cutter frame (9) are respectively arranged in the chutes (12, 13) of the upper and the lower connecting arms (10, 11). An adjusting bolt (17) goes through the round hole (14) of the fixed cutter frame (7) and the threaded hole (15) of the movable cutter frame (9), and a circlip (18) is arranged on a screw rod arranged on the inner side face which the adjusting bolt (17) goes through. The movable cutter frame (9) can move along the chutes (12, 13) correspondingly to the fixed cutter frame (7) when a handle wheel (16) arranged on the head of the adjusting bolt is rotated. The utility model is suitable for the management of the fruit trees, and can conveniently adjusting the width of the ring peeling.

Description

The band girdle device

The utility model belongs to a kind of forestry aid, specifically, is a kind of utensil that fruit tree or other trees is carried out band girdle.

Band girdle is to break up for trees such as fruit tree are germinateed, and reaches a kind of artificial operation that the nutrient that makes the blade manufacturing does not reflux and implements by cutting off the fruit tree bast.Existing band girdle device is formed by handle 1, knife rest 2 and two pointed tooth type blades 3,4 of being installed on the knife rest 2, its structure as shown in Figure 1, during use two blades 3,4 at regular intervals are cut the bark surfaces, by handle 1 blade 3,4 is circled around tree and can finish band girdle, the band girdle width depends on the spacing between the blade 3,4.The defective of this band girdle device is, spacing between two blades 3,4 is regulated, need to finish by the pad 5 between the increase and decrease blade, when needing to adjust the band girdle width when varying in size because of the branch of setting, must unload bottom knife 3,4, increase and decrease pad 5 therebetween both bothered like this, also not accurate enough, use very inconvenient.

At above-mentioned situation, the utility model proposes the novel band girdle device that a kind of blade space can be regulated easily.

The utility model band girdle device is made up of knife rest 19 that blade is installed and the handle 20 that is connected on the knife rest 19, it is characterized in that, knife rest 19 comprises the immovable support 7 that fixed blade 6 is housed, the movable carriage 9 of movable blades 8 is housed, and the last linking arm 10 that is connected and fixed knife rest 7 and movable carriage 9, following linking arm 11, the downside of last linking arm 10, the upper side of following linking arm 11 is equipped with chute 12 and chute 13 respectively, the upper and lower side of movable carriage 9 places chute 12 and chute 13 respectively, but relative fixed knife rest 7 is done parallel moving, immovable support 7, have hole, garden 14 and screwed hole 15 on the movable carriage 9, the adjusting bolt 17 that head has handle wheel 16 passes hole, garden 14 and screwed hole 15, with linking arm 10 up and down, 11 are arranged in parallel, its handle wheel 16 is positioned at the lateral surface of immovable support 7, and it passes on the screw mandrel at immovable support 7 medial surface places and is equipped with spacing jump ring 18.

When rotating handle takes turns 16, because the existence of spacing jump ring 18, make the screw mandrel can not parallel shifted, movable carriage 9 will drive 6 translations of movable blades 8 relative fixed blades along screw mandrel and chute 12,13 translations.Therefore, the spacing between two blades of the utility model band girdle device 6,8 can be taken turns 16 by handle and regulated easily.

Fig. 1 is existing band girdle device structural representation, and Fig. 2 is the utility model band girdle device structural representation.

Further specify below in conjunction with accompanying drawing, in embodiment of the present utility model, any of upper and lower linking arm 10,11 and blade 6,8 adjacent surfaces are equipped with scale 21, so that the adjusting of blade space quantizes and be more directly perceived.

The fixed blade 6 of the utility model band girdle device, the cutting edge of movable blades 8 can also be made arc, make blade be from narrow to wide variation, can accomplish like this to cut dark according to the thickness adjusting of bark, because the branch that bark is thin is thinner, can put in the narrower position of blade with the blade contact point, the branch that bark is thick and thicker can place the position of blade broad, and the degree of depth of blade in-tree is promptly different like this, changed existing sharp-tooth shaped blade and cut the strength control of dark armrest portion, inadequately defective easily.Handle 20 can adopt an end to be fixed on the linking arm, the mode of the movable overlap joint of the other end and another linking arm, handle the third 20 can be enclosed within on branch or the tree bar like this, it is more flexible to operate, the most handyly have rigidity concurrently and flexible material is made, to adapt to the variation of branch or bole thickness.

Claims

1, the band girdle device, form by knife rest that blade is installed (19) and the handle (20) that is connected on the knife rest (19), it is characterized in that, knife rest (19) comprises the immovable support (7) that fixed blade (6) are housed, the movable carriage (9) of movable blades (8) is housed, and the last linking arm (10) that is connected and fixed knife rest (7) and movable carriage (9), following linking arm (11), the downside of last linking arm (10), the upper side of following linking arm (11) is equipped with chute (12) and chute (13) respectively, the upper and lower side of movable carriage (9) places chute (12) and chute (13) respectively, immovable support (7), have hole, garden (14) and screwed hole (15) on the movable carriage (9), the adjusting bolt (17) that head has handle wheel (16) passes hole, garden (14) and screwed hole (15), with linking arm (10 up and down, 11) be arranged in parallel, its handle wheel (16) is positioned at the lateral surface of immovable support (7), and it passes on the screw mandrel at immovable support (7) medial surface place and is equipped with spacing jump ring (18).

2, band girdle device according to claim 1 is characterized in that, the surface that any of upper and lower linking arm (10,11) is adjacent with blade (6,8) is equipped with scale (21).
