Abstract
The utility model provides a saddle-shaped tobacco leaf picking knife. The picking knife is an irregular saddle-shaped plate body (1) with a knife back on one side and a knife tooth (4) on the other side, wherein a mounting notch (2) is formed in the middle section of one side of the knife back; mounting holes (3) are formed in the two sides of the notch on the plate body; one side of the knife tooth is in a saddle shape with an arc-shaped notch (5) in the middle. The picking knife is made of a flexible material. The saddle-shaped tobacco leaf picking knife is simple in structure and is suitable for tobacco leaf picking conditions in China; particularly, the picking efficiency is high when the saddle-shaped tobacco leaf picking knife is used for picking lower leaves and middle leaves of tobacco plants; the damaging rate of the tobacco leaves is low and the net picking rate is high.
Description
Technical field
The utility model relates to the picking knife technical field of structures of tobacco leaf picking mechanical.。
Background technology
Tobacco leaf picking machine is a kind of equipment of the tobacco leaf of gathering, and it utilizes motor driven to drive harvesting blade movement to complete tobacco leaf picking work.For a long time; China's leaf tobacco production owing to being subject to, plant, large-scale degree is low and the restriction of tobacco grower's economic condition by fragmentary dispersion; the application of tobacco agriculture machinery is less; technical merit is lower; especially tobacco leaf picking mechanical technique is comparatively backward, and in production reality, seldom application machine equipment is plucked tobacco leaf, is all conventionally to rely on tobacco grower to gather by hand; labour intensity is large, production efficiency is low, has restricted the sustainable development of leaf tobacco production.Developed countries is as tobacco planting countries such as the U.S., Canada, Japan, and the tobacco leaf picking machine of existing various semi-mechanizations or mechanization comes into operation at present, and the efficiency of gathering is high, can complete in time the operation of gathering.But the picking knife of external various harvester does not meet Chinese tobacco plantation actual conditions, and the efficiency of gathering is low, and the tobacco leaf badly broken of harvesting, and complex structure, be difficult to effectively be applied.
Utility model content
The purpose of this utility model is for above-mentioned the deficiencies in the prior art, provide a kind of simple in structure, be suitable for China's tobacco leaf picking situation, the shape of a saddle tobacco leaf picking knife that especially picking efficiency is high in the time plucking cigarette strain bottom leaf and middle leaf, tobacco leaf breakage rate is low, pick up rate is high.
The purpose of this utility model is achieved through the following technical solutions.
Shape of a saddle tobacco leaf picking knife, this picking knife is that a side is that the knife back, opposite side are the irregular shape of a saddle plate bodys of cutter tooth, the knife back one side stage casing offers installation gap, and plate body is positioned at breach both sides and offers installing hole, and cutter tooth one side is the shape of a saddle that there is arc notch at middle part; Picking knife adopts flexible material to make.
Flexible material described in the utility model is natural rubber or silica gel.The total length of described plate body is 100～260mm, and overall width is 60～80mm, and thickness is 8～10mm.
The utility model is that applicant is according to China's tobacco leaf planting and the feature of gathering, by analytical calculation and lot of experiments, the picking knife obtaining for the mechanism design of gathering of tobacco leaf picking machine, it is simple and reasonable, easy to use, the material of making picking knife is flexible, not only can improve the efficiency of tobacco leaf picking, also can effectively reduce breakage rate, through applicant's evidence, when this picking knife is plucked cigarette strain bottom leaf and middle leaf, picking efficiency is high, tobacco leaf breakage rate is low, pick up rate is high, and easy to use, be convenient to maintenance, be specially adapted to the mechanism that gathers of automatic or semi-automatic tobacco leaf picking machine.
Further set forth content of the present utility model below in conjunction with Figure of description.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in the figure, this shape of a saddle tobacco leaf picking knife one side is that the knife back, opposite side are cutters tooth 4, and entirety is irregular shape of a saddle plate body 1.Offer installation gap 2 in the knife back one side stage casing, power transmission shaft termination can be goed deep in breach 2.Plate body is positioned at four installing holes 3 of breach both sides processing, by installing hole 3, plate body 1 is fixed on power transmission shaft.Cutter tooth one side is the shape of a saddle that there is arc notch 5 at middle part.When use, need two cover tobacco leaf picking knife is symmetrical to install, when symmetrical installation, two to overlap the distance that the distance two between the Fruit-Picking Area of tobacco leaf picking knife overlaps between picking knife cutters tooth 4 be 50～80mm.Picking knife adopts flexible material to make, and described flexible material is natural rubber or silica gel or other suitable flexible material.Quantity and installation interval at the picking knife installed in mechanism of gathering can be adjusted, to adapt to gathering of variety classes tobacco leaf.According to actual needs, on one side can be between 100～260mm by the total length of plate body 1, overall width is 60～80mm, thickness is 8～10mm.
The utility model is installed to automatic or automanual tobacco leaf picking machine by the installing hole 3 on plate body 1 and gathers on the power transmission shaft of mechanism, drives picking knife to be rotated by power transmission shaft.In the rotary movement of picking knife, cutter tooth 4 is contact tobacco leaf stem root constantly, stem root is applied to downward pressure tobacco leaf is fractureed, and then complete gathering of tobacco leaf.Meanwhile, picking knife is installed afterwards and cigarette strain is the angle of 5～10 °, makes picking knife in the time of work, can not pull cigarette strain.
Claims (3)
1. shape of a saddle tobacco leaf picking knife, it is characterized in that, this picking knife is that a side is that the knife back, opposite side are the irregular shape of a saddle plate bodys (1) of cutter tooth (4), the knife back one side stage casing offers installation gap (2), plate body is positioned at breach both sides and offers installing hole (3), and cutter tooth one side is the shape of a saddle that there are arc notch (5) at middle part; Picking knife adopts flexible material to make.
