The harvesting mechanism comprises a tobacco leaf isolation part and a leaf threshing part which is arranged below the tobacco leaf isolation part, wherein the tobacco leaf isolation part comprises a front combined connecting piece, a rear combined connecting piece (8), a horizontal rectangular guide plate (6), a triangular guide plate (1) and a guide rod (6a); the horizontal rectangular guide plate (6) is arranged between the front combined connecting piece and the rear combined connecting piece; the triangular guide plate (1) is arranged at an inward necking in the front end of the front combined connecting piece; and the guide rod (6a) is arranged on the horizontal rectangular guide plate. The harvesting mechanism has a simple structure, is lower in manufacturing cost and can be used for separately picking up lower leaves and middle leaves of the tobacco plants at different times without damaging the tobacco plants and the tobacco leaves which are not harvested.
Description
Technical field
The present invention relates to a kind of apparatus structure technical field of tobacco leaf of gathering.
Background technology
In leaf tobacco production process, can the harvesting of tobacco leaf be basic work, pluck timely and can affect quality of tobacco to a great extent.During tobacco leaf picking, because the maturity of cigarette strain each several part tobacco leaf is different with proterties, and the baking process of each several part tobacco leaf is different, therefore tobacco leaf gather be generally tobacco leaf is divided into inferior leads, middle leaf, upper leaf to carry out branch, timesharing gathers.Inferior leads is ripe at first, inferior leads of therefore first gathering, gather respectively more afterwards middle leaf and upper leaf.Abroad, the seed harvester of existing various semi-mechanization and mechanization comes into operation, and picking efficiency is higher, and can complete harvesting operation in time, but overseas equipment structure is more complicated, manufacturing cost is higher, and the tobacco leaf being difficult to adapt to China's vega is plucked.Domestic also once had some simple tobacco leaf picking machineries, automatically the gathering of tobacco leaf can be realized, collect and fill basket, have that harvest efficiency is high, net harvesting rate high, compared with external type, structure is simple, advantage of lower cost, but its picking methods and function singleness, not only can not take to different parts tobacco leaf the picking methods that adapts, also usually damage middle leaf when gathering inferior leads, gather middle leaf time damage upper leaf, serious to cigarette strain damage, substantially seldom use at present.Therefore the tobacco leaf picking of China also mainly relies on artificial harvesting, and picking efficiency is low, and tobacco grower's labour intensity is large, and is difficult to ensure the timely harvesting to a large amount of tobacco leaf.
Summary of the invention
The object of the invention is for above-mentioned the deficiencies in the prior art, provide a kind of structure simple, manufacturing cost is lower, can pluck the inferior leads of cigarette strain and middle leaf Divisional, timesharing, also can not damage cigarette strain and not adopt the mechanism that gathers of tobacco leaf.
Object of the present invention is achieved through the following technical solutions.

Embodiment
As shown in the figure, a kind of cigarette strain middle and lower part tobacco leaf picking mechanism, comprises tobacco leaf isolated part and is installed on and beat leaf part below tobacco leaf isolated part.The effect of tobacco leaf isolated part is that the tobacco leaf preventing top from not adopting is adopted by mistake and damaged, and includes front combined connection component and rear combined connection component 8, is installed on the horizontal rectangular guide plate 6 between front combined connection component and rear combined connection component, the triangle guide plate 1 being installed on the inside closing in of front combined connection component front end, the guide post 6a be installed on horizontal rectangular guide plate 6.Triangle guide plate 1 be a right-angle side outwardly, another right-angle side is installed on modification of right-angled triangle plate on horizontal hinge 13, and the bottom of triangle guide plate 1 is provided with bracing frame 15.Described front combined connection component comprises the inserted link sub-assembly be made up of horizontal internal thread pipe box 2c on inserted link of upright inserted link 2a and sidewall weld and the first locking nut 2d of piercing into horizontal internal thread pipe box 2c, insert the levelling lever 11 be made up of preceding thread section and rear smooth section in horizontal internal thread pipe box 2c, by threaded sleeve 14b be enclosed within levelling lever thread segment by threaded sleeve and the fixed head sub-assembly 14 that is welded on connecting plate 14a on threaded sleeve and forms to the clamping screw 14c of levelling lever 11 through threaded sleeve top, be sleeved on the horizontal hinge 13 of levelling lever 11 smooth section.Levelling lever 11 and fixed head sub-assembly 14 are linked together by clamping screw 14c and lock.The both sides hinge of horizontal hinge 13 is connected with triangle guide plate 1 and horizontal rectangular guide plate 6 respectively.Triangle guide plate 1, owing to being arranged on horizontal hinge, can swing up and down in the process being traveling in vega, avoids being pressed down when tobacco leaf enters flexible picking leaves blade position.Described rear combined connection component comprises the link plate 8a longitudinally offering one group of installing hole 8d, the connecting plate 8b being welded in link plate top, the attachment screw 8c be fitted on connecting plate.Horizontal rectangular guide plate 6 offers kidney-shaped installing hole 6c, and attachment screw 8c will link together with connecting plate 8b with horizontal rectangular guide plate 6 through kidney-shaped installing hole 6c.Attachment screw 8c can move left and right in kidney-shaped installing hole 6c, regulates the right position of link plate 8a with this.Guide post 6a is installed on inside horizontal rectangular guide plate 6.The both sides of horizontal rectangular guide plate 6, with flanging 6b, can prevent the strain of scratch cigarette.Beat leaf part and include the flexible picking leaves blade 5 being positioned at and being installed on below horizontal rectangular guide plate 6 on horizontal torsion pressing plate 4, the front end of horizontal torsion pressing plate 4 is connected with the vertical connecting 16 that upper end is socketed on levelling lever 11 by connecting axle 12 and spherical plain bearing rod end 3, and the rear end of horizontal torsion pressing plate 4 is connected with gerotor motor 9 by shaft coupling 7 and positioning sleeve 10.Gerotor motor 9 is installed on link plate 8a.By realizing the adjustment to flexible picking leaves blade 5 height and position in the installing hole 8d that gerotor motor is installed on differing heights on link plate, to adapt to gathering of differing heights position tobacco leaf.Flexible picking leaves blade 5 is the blade made of rubber or nylon of double-sided belt waveform cutter tooth.Inserted link sub-assembly, levelling lever 11, combined connection component 8 interoperation, can regulate the height of tobacco leaf isolated part, thus better protect immature tobacco leaf.Beat the spherical plain bearing rod end 3 of leaf part will beat leaf part and be connected with tobacco leaf isolated part, and the rotating part be made up of connecting axle 12, flexible picking leaves blade 5, horizontal torsion pressing plate 4, shaft coupling 7 when leaf is beaten in guarantee is rotatable.Gerotor motor 9 is by transmission of power to horizontal torsion pressing plate 4, and horizontal torsion pressing plate 4 rotates and drives flexible picking leaves blade 5 to rotate, and is laid by tobacco leaf.Flexible picking leaves blade damages tobacco rod or is interrupted by tobacco rod when can prevent from beating leaf.Gather tobacco leaf time, two groups of symmetrical mechanisms that gather are installed as shown in Figure 3, cigarette strain enters two along V2 velocity attitude and gathers in the middle of mechanism under the guiding of triangle guide plate 1, two gerotor motors drive flexible picking leaves blade to rotate and are laid by tobacco leaf, and tobacco leaf falls within conveying mechanism 17 and exports along V1 direction.
