CN2059788U - Picking cutter head for cone of conifer - Google Patents

Abstract

The utility model relates to a cone picking cutter head. The chief picking objects of the utility model are the cones of the scotch pine and the pitch pine. In view of the maximum characteristics of the breaking force and the cutting resistance force of the cone stalk, under the condition of difficulty picking the cone, the utility model is designed. The cutter head is characterized in that the cutter head has a spherical surface shape, and is composed of a plurality of cutter teeth; the cutter teeth are radially arrayed; the root segment of the cutter teeth is provided with a cutting edge; the center of the cutter head is provided with a circular hole which is fixed and connected with a long rod. When the utility model is used, people can pick the cone of the conifer on ground; or the utility model and a lifting device are matched to be used for picking the cone of the conifer. The utility model has the advantages of labor saving, portability and flexible operation, and the utility model does not hurt the mother tree.

Description

Picking cutter head for cone of conifer

It is one of forest seed collection facility in the forestry machinery subject that the coniferous tree cone is plucked cutterhead, belongs to coniferous tree cone harvesting technique field.International monopoly retrieval AOID46/00 and AOID46/24.

At present in existing domestic and international correlation technique and the relevant technologies data, consult by retrieval, as: CN86202088, SU869638, US4226075, files such as the collection of the forest tree seed handbook chapter 4 seed that the World Food Programme publishes are different fully with this harvesting cutterhead, and at present external forest tree seed is gathered mechanization and developed to both direction: a direction is the small-sized facility of development, promptly develops light equipment of ascending a height and harvesting facility, as the hook of collecting seed, collect seed and shovel, the rake of collecting seed, the comb etc. of collecting seed; Another direction is the large-scale seed collecting equipment of development, as with the vehicle being the jib lifting cone collecting device on chassis, tree shaker, pneumatic pick device, and the seed collecting equipment that carries of helicopter or balloon etc., at home, the harvesting technique of forest tree seed is relatively backward for a long time, plucks based on manual, also has above-mentioned Chinese patent, as CN85201119, CN86204578 etc. also are hand toolss.In above-mentioned every relevant technologies, the picking device complex structure of scissors and cutting type is operated lightly inadequately, and is unsuitable for plucking growth orientation different cone; The fruit picking apparatus of other pattern because harvesting power is very little, all is unsuitable for plucking the coniferous tree cone, because the adhesion of the carpopodium of coniferous tree cone and fruit branch is much bigger; And several cones comb cleaning devices and picker are mounted on the large-scale equipment of gathering in the Russian Patent.

The purpose that the present utility model is created, be that cone with pinus sylvestris var. mongolica and Chinese pine is the main object of plucking, at the pull-off force of cone carpopodium and the characteristic of cutting resistance maximum, that is to say, overcome the greatest difficulty of plucking cone, a kind of light cone of specialized designs is plucked cutterhead, does not hinder elite stand and laborsaving when this cutterhead uses, and characteristics such as light, flexible operation are arranged.For reaching this purpose, need to solve following several critical technical problems.One will have blade on the instrument, plays certain dissection, reduces harvesting power.Its two, two blade oblique falls in the blade wedge angle carpopodium, to carry out sliding cutting and draw cut together.Its three, form a plurality of blade indent wedge angles, to improve the probability of cutting carpopodium, a plurality of cutters tooth are arranged promptly, the cutter tooth root is the indent wedge angle.Its four, the cutter tooth radial arrangement forms tooth-like cutterhead, to be suitable for plucking the different cone in growth orientation.Its five, front tooth part for the circle blunt, cutting edge begins from tooth rear portion 1/3, so that it does not hinder elite stand.

The utility model description of drawings:

Fig. 1 is a front view of the present utility model.

Fig. 2 is an end view of the present utility model.

The utility model cutterhead is an overall structure, in Fig. 1 and Fig. 2:

The spherical shape of 1-solid cutter;

The 2-cutting tool shape;

The knife edge part of 3-cutter tooth is rasped between two cutters tooth by the profiling emery wheel;

4-cutterhead center hole is used for mounting screw, and cutterhead is connected with the elongation rod member.

This picking cutter head for cone of conifer is characterized in that cutterhead 1 is a plurality of cutters tooth 2 compositions of a spheric, and the integral body of cutter tooth is as the criterion with center hole 4 and is radial arrangement to the four directions. The cutter tooth root is blade 3, occupies 1/3rd length of cutter tooth, is the main position of cutting cone carpopodium, and the anterior no blade of cutter tooth, play the guide effect before the cutting cone handle, do not injure elite stand, be a circular arc two adjacent cutter tooth junctions and have blade. There is a small sircle hole 4 at the cutterhead center, is used for installing and fixing when rod member is connected with extending. Can cooperate from ground or with the equipment of ascending a height during application and pluck acerose cone, be particularly suitable for plucking the cone of pinus sylvestris var. mongolica and Chinese pine.

Advantage of the present utility model: one, this cutterhead is the cutter tooth of radial structure, has the indent bidentate of a plurality of directions, flexibly the cone around the cutter plate.Its two, cutterhead becomes sphere shape, can make the seed collecting workman pluck cone from the diverse location on ground or the tree.Its three, circular arc and cone carpopodium size that blade is arranged in its root of tooth root position adapt, and control stick is vertical with sphere.When plucking cone, combination is then drawn, is cut in the upper and lower effect of lever handle., just can pull out a nail to horizontal effect as lever handle,, very easily cone be adopted down by leverage as the hammer of twitching one's mouth.So this picker is very laborsaving, do not injure elite stand again, to the Chinese pine cones of the most difficult harvesting (see figure 2) of yet handling very skillfully.Its four, cutterhead itself is very light, its weight be no more than 150 the gram.

Embodiment: pinus sylvestris var. mongolica and Chinese pine cones are plucked the making of cutterhead.

No. 45 steel sheet metals that cutterhead material: 2mm is thick.

Cutterhead shape: see Fig. 1,2.

The number of teeth: 8.

The straight warp of outside circle: 160mm.

The straight warp of angle between teeth transition circle: 5mm.

The straight warp of cutterhead center hole: 6mm.

Heat-treatment quenching: Rockwell hardness HRC50-55.

Cutterhead after Overheating Treatment is with small-sized saw sharpener sharpening.

Claims (3)

1, a kind of coniferous tree cone is plucked cutterhead, it is characterized in that: cutterhead 1 is that a plurality of cutters tooth 2 of a sphere shape are formed, and the integral body of cutter tooth is as the criterion with center 4 and is radial arrangement to the four directions, has blade 3 on the cutter tooth.

2, cutterhead according to claim 1 is characterized in that: blade is the tooth root position at cutter tooth, occupies 1/3 length of cutter tooth, and all the other positions do not have blade.

3, cutterhead according to claim 1 is characterized in that: two adjacent cutter tooth junctions are a circular arc, and have blade.
