2) scion tobacco seedlings feeding operation loads the band body region below scion cutting mechanism non-on scion tobacco seedlings conveyer belt Scion tobacco seedlings: i.e. by the matrix frame bottom of scion tobacco seedlings root and accordingly with the fixed frame grafting on body region；

3) scion cutting operation, control scion tobacco seedlings conveyer belt rotate and scion tobacco seedlings are moved under scion cutting mechanism Side, the mobile standard in place of scion tobacco seedlings are between the first, second scion fixture block of scion fixture for each tobacco seedlings, because The central point spacing of adjacent slide block and the central point spacing of adjacent fixed frame are identical on transmission belt, as long as so guaranteeing scion cigarette When tobacco seedlings at seedling conveyer belt upper extreme point are located between the fixture block of corresponding position scion fixture, the tobacco seedlings at other positions are all located at pair Between the fixture block that should locate scion fixture, the output end for then controlling scion pusher cylinder drives the first, second scion cutting rack pair To being moved to minimum spacing and the first, second scion fixture block opposite direction made to clamp scion tobacco seedlings stalk, while corresponding cutting this moment The level board docking of two bending plates forms the cabinet along cutting rack length direction open at both ends on frame, and the vertical band on bending plate exists The opening of the cabinet is blocked under gravity, so that case vivo environment keeps semi-closed state, and controlling water pump will sterilizing By feed liquor tube pump to atomizer, sterilized solution is atomized and is sprayed at the cabinet sterilized solution in liquid container by atomizer Interior, the output end for then controlling scion cylinder drives scion cutter mobile, and scion cutter contacts scion fixture in moving process Scion tobacco seedlings stalk at bottom surface simultaneously cuts off stalk, and the output end for then controlling scion cylinder drives scion cutter to reset, and cuts Process is cut since the sterilized solution after cabinet is atomization exists, prevents issuable germ growth or cross-infection phenomenon from occurring, It can be also infected with sterilized solution on scion tobacco seedlings stalk and scion fixture simultaneously, to maintain the sterilizing of certain state in subsequent job Effect；

Then control scion tobacco seedlings conveyer belt rotates backward, and the drive of scion tobacco seedlings conveyer belt only stays stalk and the tobacco seedlings of root to remove Below scion cutting mechanism, the related scion tobacco seedlings root of corresponding matrix frame, stem are removed from fixed frame and used it for anything else；If only When staying stalk and the tobacco seedlings of root as waste, collecting mechanism can be set below scion tobacco seedlings conveyer belt, it so can be with Control scion tobacco seedlings conveyer belt continues to rotate, and the drive of scion tobacco seedlings conveyer belt only stays the tobacco seedlings of stalk and root to be moved to conveyer belt Lower section, and fallen in collecting mechanism by gravity, the unification of staff's later period is collected the matrix frame in collecting mechanism, residual The tobacco seedlings rhizome and matrix stayed makees the processing such as fermented manure.

The operations such as cylinder, conveyer belt, transmission belt can also can specifically cut in above-mentioned scion cutting operation with manual control Cut frame, scion transmission belt, the size of scion tobacco seedlings conveyer belt, installation site and corresponding scion fixture, slide block and matrix After the quantity of frame, transmission speed and the displacement of each scion tobacco seedlings conveyer belt and scion transmission belt can be determined, and then pass through Process control or setting travel switch or/and delayer carry out automation control to conveyer belt, transmission belt and each cylinder, on It states process and principle description only is made to the course of work of the present invention.

After the output end of scion cylinder drives scion cutter to reset, scion fixture and folder on the first, second cutting rack Tobacco seedlings stalk in tool is mobile in the effect of scion transmission belt simultaneously and the work of stock cutter device is cooperated to carry out grafting operation, The grafting operation process is described in detail in lower section.

Stock cutter device:

1) output end of stock fixture feeding operation, first control stock pusher cylinder pushes the first, second stock cutting rack Minimum spacing, the i.e. maximum spacing of the first, second stock cutting rack spacing and the stock drive block of stock fixture are in the two It is identical, it is then that the ambilateral stock position limiting slide block of several stock clamps is sliding with the stock on the first, second stock cutting rack simultaneously Rail cooperation, the preferred operations during being somebody's turn to do are as follows: so that the stock of the stock fixture transmission mechanism on the first, second stock cutting rack Transmission belt slowly and is at the same speed driven, while manual operation cooperates stock fixture and stock sliding rail, when on stock transmission belt It, can be quickly by next anvil when slide block contacts the ambilateral drive block of stock clamp and stock fixture is driven to move along stock sliding rail Timber grab and stock sliding rail cooperate, and repeat operation until being covered with stock fixture on stock cutting rack, then control stock pushes away Cylinder of taking offence drives the first, second stock cutting rack to reset, due to the cooperation of stock sliding rail and stock position limiting slide block, so that stock clamp First, second stock fixture block of tool overcomes the adsorption capacity of magnet layer and separates；

2) stock tobacco seedlings feeding operation, will on stock tobacco seedlings conveyer belt be located at stock cutter device charging extreme direction and it is non-be in anvil Stock tobacco seedlings are loaded with body region below the wooden cutting mechanism: i.e. by the matrix frame bottom of stock tobacco seedlings root and corresponding band body portion Fixed frame grafting on position；

3) stock cutting operation, control stock tobacco seedlings conveyer belt rotate and stock tobacco seedlings are moved under stock cutting mechanism Side, the mobile standard in place of stock tobacco seedlings are between the first, second stock fixture block of stock fixture for each tobacco seedlings, because The central point spacing of adjacent slide block and the central point spacing of adjacent fixed frame are identical on transmission belt, as long as so guaranteeing stock cigarette When tobacco seedlings at seedling conveyer belt upper extreme point are located between the fixture block of corresponding position stock fixture, the tobacco seedlings at other positions are all located at pair Between the fixture block that should locate stock fixture, the output end for then controlling stock pusher cylinder drives the first, second stock cutting rack pair To being moved to minimum spacing and the first, second stock fixture block opposite direction made to clamp stock tobacco seedlings stalk, while stock fixture block bottom Notch take advantage of a situation and realize inserting with the fixture block of corresponding matrix frame top surface, while corresponding to the level board of two bending plates on cutting rack this moment Docking forms the cabinet along cutting rack length direction open at both ends, and the vertical band on bending plate blocks the case under the effect of gravity The opening of body so that case vivo environment keeps semi-closed state, and controls water pump and passes through the sterilized solution to sterilize in liquid container To atomizer, sterilized solution is atomized and is sprayed in the cabinet feed liquor tube pump by atomizer, then controls stock cylinder Output end drives stock cutter mobile, and stock cutter contacts the stock tobacco seedlings stalk at stock fixture top surface simultaneously in moving process Stalk is cut off, then control stock cylinder output end drive stock cutter reset, cutting process due to cabinet it is atomization after Sterilized solution exist, prevent that issuable germ from breeding or cross-infection phenomenon occurs, while stock tobacco seedlings stalk and anvil Also sterilized solution can be infected on timber grab, to maintain the sterilization effect of certain state in subsequent job；

Then the drive of control stock tobacco seedlings conveyer belt only stays stalk and the tobacco seedlings of root to continuously move to be transferred at device for grafting Operation is connect, which is described in detail in lower section.

The operations such as cylinder, conveyer belt, transmission belt can also can specifically cut in above-mentioned stock cutting operation with manual control Cut frame, stock transmission belt, the size of stock tobacco seedlings conveyer belt, installation site and corresponding stock fixture, slide block and matrix After the quantity of frame, transmission speed and the displacement of each stock tobacco seedlings conveyer belt and stock transmission belt can be determined, and then pass through Process control or setting travel switch or/and delayer carry out automation control to conveyer belt, transmission belt and each cylinder, on It states process and principle description only is made to the course of work of the present invention.

As waste by cutting tobacco seedlings stalk, falls or fall naturally on stock tobacco seedlings conveyer belt and in stock It is moved to realization below band body under the drive of tobacco seedlings conveyer belt to fall, therefore collection can be set below stock tobacco seedlings conveyer belt Mechanism so can uniformly collect the tobacco seedlings stalk fallen and make the processing such as fermented manure.

Fixture relies primarily on the curved slab in its channel steel to clamp tobacco seedlings, by the size design to fixture, can make it Size meets the outer diameter clamping demand of tobacco seedlings to be processed as far as possible, at the same in order to be realized as far as possible to the stable holdings of tobacco seedlings and It reduces extruding caused by the clamping to tobacco seedlings to injure, the present invention is pasted in the inner wall of curved slab is equipped with spongy layer, spongy layer tool There are good gas permeability and elasticity, spongy layer can not only reduce the hard squeeze operation power to tobacco seedlings, can also improve it To the friction holding power of tobacco seedlings, simultaneously because the outer diameter of tobacco seedlings can not be completely the same, so the appropriate deformation of spongy layer can be with Improve clamping adaptability of the fixture to more tobacco seedlings in range being in outer diameter numerical value change.

Finishing for complete work flow as scion cutter device and stock cutter device is on its cutting rack Corresponding fixture and fixture in tobacco seedlings position all remove cutting rack and participate in grafting operation subject to.Complete a job stream The cutting rack of scion cutter device and stock cutter device after journey resets under the effect of corresponding pusher cylinder, and carries out next A complete work flow carries out feeding and cutting again.

It should be noted simultaneously that modern industry can guarantee the operation of scion, stock pusher cylinder output end as far as possible Stationarity can guarantee that corresponding cutting rack only does horizontal opposite movement and ensures the fixture fixture block on cutting rack in sliding rail as far as possible Shaking will not be generated, in addition slide block and the contact of drive block on fixture block in turn ensure fixture block in the limit of a horizontal direction, So can guarantee that fixture fixture block will not be generated in and while clamping tobacco seedlings stalk mobile with cutting rack along sliding rail length direction Movement the contact surface of position limiting slide block or/and sliding rail on fixture block can be carried out at the roughness on surface certainly for insurance Reason rationally improves the contact friction force of position limiting slide block and sliding rail on the basis of not influencing transmission belt drive fixture block movement.

Operation is grafted to the last one step of workflow of the present invention below to be described:

Graft operation:

1) the stock fixture after stock cutter resets is sliding along stock under the action of stock transmission belt and stock tobacco seedlings conveyer belt Rail is mobile and sequentially removes stock cutting rack (stock fixture while driving and stock transmission belt by stock tobacco seedlings conveyer belt The limit of upper slide block makes so stock tobacco seedlings conveyer belt and stock transmission belt need same transmission speed to work in this process Obtaining stock fixture and its interior stock tobacco seedlings can steadily move), after stock fixture removes stock cutting rack, due to its bottom The fixture block inserting of notch and corresponding matrix frame supports so being realized by matrix frame to stock fixture.Wherein, stock is removed earliest to cut The transmission for stopping stock tobacco seedlings conveyer belt and stock transmission belt when the stock fixture of frame is moved at device for grafting is cut, is passed simultaneously The output end of cylinder of taking offence drives the two mobile composition squares of grafting channel steel opposite directions and hollow grafting frame, and by corresponding stock fixture Packet is in wherein sky portion；

2) in the above process, the scion fixture after scion cutter resets is moved simultaneously under the action of scion transmission belt along scion sliding rail Scion cutting rack is sequentially removed, when two grafting channel steel compositions graft framves and encase stock fixture, corresponding scion fixture is removed Scion cutting rack simultaneously enters grafting frame (scion transmission belt stops transmission this moment) from the notch of grafting top of the trellis, and by under self weight It falls until contact grafts the stock fixture in frame and realizes docking, since scion cutter and stock cutter are parallel, so stock Fixture may be implemented effectively to dock with the tobacco seedlings stalk in scion fixture.During being somebody's turn to do, due to stock, scion fixture and grafting Frame is in square, after determining the size of grafting frame and fixture, it can be ensured that grafting frame and fixture realize clearance fit, and meet Mobile nothing of the scion fixture inside grafting frame circumferentially rotates.It is limited by the grafting to grafting channel steel inner wall or/and scion fixture Position sliding block makees surface roughness processing, and the frictional force of Lai Tigao scion position limiting slide block and grafting frame reduces the whereabouts of grafting fixture Speed, it should be noted simultaneously that, the whereabouts displacement of scion fixture will not be excessively high, shows that the displacement is according to practical operation 10-15cm, so not will cause the contact with stock fixture of scion fixture generates excessive impact.

3) scion fixture and stock fixture realize the Grafting clip for adsorbing and being formed an entirety by the magnet layer of drive block Then tool controls drive cylinder output end and two grafting channel steels resets is driven to realize separation, stock tobacco seedlings conveyer belt, stock transmission belt And scion transmission belt continues to be driven, and drive cylinder and grafting channel steel is cooperated to repeat above-mentioned grafting operation, until cutter device Complete an entire flow operation；

4) the grafting fixture that scion fixture is formed after docking with stock fixture is worked in stock tobacco seedlings conveyer belt transmission process Personnel collect, i.e., separate corresponding matrix frame with fixed frame, will be clamped with the grafting fixture of tobacco seedlings after grafting and are placed in Certain time in culture environment, after tobacco seedlings wound healing completes final grafting, separating clamp takes out tobacco seedlings.

It should be noted that the control of cylinder, transmission belt, conveyer belt can pass through Numeric Control Technology in operation process of the present invention It realizes, such as PLC control device etc. realizes the control to above-mentioned driving mechanism, fully achieves factory operation.While tobacco seedlings The feeding of the feeding of feeding and corresponding fixture, especially tobacco seedlings may be by artificial more safe.

Compared with the prior art, the invention has the following advantages:

Factory operation is realized, the present invention assigns strength support and cut direction, position of the tobacco seedlings in cutting by fixture Restriction, it is ensured that there is identical notch as stock and scion tobacco seedlings and be effectively protected, while passing through each transmission The mutual coordinated of mechanism realizes the notch docking of the tobacco seedlings inside fixture, and using fixture to the cigarette after notch docking Seedling realizes support, may be implemented completely the tobacco seedlings of mass from cutting, docking, Wound healing overall operation.And cutter machine Sterilization treatment is fixed and introduced to toolization control, overall operation environment, reduces tobacco seedlings because of germ sense caused by grafting cutting Dye rate.
