The working process of the invention is as follows:

firstly, it should be noted that the tobacco seedlings grafted by the oblique planes need to grow consistently, especially the diameter and height, as the stock and the scion, so as to improve the survival rate of the grafted tobacco seedlings. Simultaneously as the stage of growing seedlings of this application last step when emerging to the tobacco seedling, perhaps before the tobacco seedling grafting, need utilize the matrix frame to carry out the centre gripping hasp with the root system of every tobacco seedling and the matrix of taking certainly, on the basis of carrying out the support to the tobacco seedling, realize the protection to the tobacco seedling root system. The tobacco seedling cultivation device is characterized in that the magnet layer on the butt joint surface of the first frame body and the second frame body is used for adsorption, so that the hollow structure formed by the first frame body and the second frame body can be used for holding the tobacco seedling roots and attached substrates, the tobacco seedling stalks are exposed from the open top of the hollow structure, and as the modern tobacco seedling cultivation all adopts floating seedling cultivation, the root and substrate volume differences are small, and the standardized standard production of the first frame body and the second frame body is realized in a phase-changing manner.

Stock cutting device:

1) anvil wood anchor clamps material loading operation, the output that at first controls to promote the cylinder promotes first, second cutting frame to be in minimum interval to both, and first, second cutting frame interval is the same with the biggest interval of the drive block of anvil wood anchor clamps promptly, then cooperates the spacing slider of several anvil wood anchor clamps both sides with the slide rail on first, the second cutting frame simultaneously, and preferred operation in this process is: the driving belts of the clamp driving mechanisms on the first cutting frame and the second cutting frame are driven slowly and at the same speed, meanwhile, the anvil wood clamp is matched with the sliding rail through manual operation, when the poking block on the driving belts contacts with the driving blocks on two sides of the anvil wood clamp and drives the anvil wood clamp to move along the sliding rail, the next anvil wood clamp can be matched with the sliding rail quickly, the operation is repeated until the anvil wood clamp is fully distributed on the cutting frames, then the pushing cylinder is controlled to drive the first cutting frame and the second cutting frame to reset, and due to the matching of the sliding rail and the limiting sliding block, the first clamping block and the second clamping block of the anvil wood clamp are separated by overcoming the adsorption force of the magnet layer;

2) stock tobacco seedling material loading operation, with lie in cutting device feed end direction and the area body position that is not in the cutting mechanism below on the tobacco seedling conveyer belt and load the tobacco seedling: namely, the bottom of the substrate frame at the root of the tobacco seedling is spliced with the fixed frame on the corresponding belt body part;

3) the stock cutting operation, control the tobacco seedling conveyer belt to rotate and make the tobacco seedling move to the lower side of the cutting mechanism, the standard that the tobacco seedling moves in place is that each tobacco seedling is just between the first clamping block and the second clamping block of the stock clamp, because the distance between the central points of the adjacent poking blocks on the transmission belt is the same as that between the central points of the adjacent fixing frames, so as long as the tobacco seedling at the upper end point of the tobacco seedling conveyer belt is ensured to be positioned between the clamping blocks of the corresponding stock clamp, the tobacco seedlings at other positions are all positioned between the clamping blocks of the corresponding stock clamp, then the output end of the push cylinder is controlled to drive the first cutting frame and the second cutting frame to move oppositely to the minimum distance and make the first clamping block and the second clamping block clamp oppositely clamp the tobacco seedling stalk, meanwhile, the notch at the bottom of the clamping block is inserted and matched with the clamping block at the top surface of the corresponding matrix frame, then the output end of the cylinder is controlled to drive the cutter to move, the cutter contacts the tobacco seedling stalk at the top, then the output end of the control cylinder drives the cutter to reset;

then controlling the tobacco seedling conveying belt and the conveying belt to rotate at the same speed and driving the tobacco seedlings only with the stems and roots to completely move out of the cutting frame, and after the anvil wood clamp moves out of the cutting frame, because the bottom notches of the anvil wood clamp are inserted and matched with the clamping blocks corresponding to the matrix frame, the matrix frame supports the anvil wood clamp. And finally, conveying the corresponding tobacco seedlings in the matrix frame by using a tobacco seedling conveying belt, manually collecting the tobacco seedlings, and grafting the tobacco seedlings with the scions obtained by adopting a similar method. As the discarded object by the cutting tobacco seedling stem stalk, drop naturally or drop on the tobacco seedling conveyer belt and move to the area body below under the drive of tobacco seedling conveyer belt and realize dropping, consequently can set up in the tobacco seedling conveyer belt below and collect the mechanism, so can unify the tobacco seedling stem stalk of collecting the dropping and do treatments such as fermentation compost.

It should be noted that, in the operation process of the present invention, the control of the cylinder, the transmission belt and the conveyor belt can be realized by a numerical control technology, for example, a PLC control device or the like realizes the control of the driving mechanism, and completely realizes the factory operation. Meanwhile, the feeding of the tobacco seedlings and the feeding of the corresponding clamps, particularly the feeding of the tobacco seedlings, can be more stable by manpower.

The clamp mainly depends on a curved plate in a channel steel to clamp the tobacco seedlings, the size of the clamp can meet the requirement of clamping the outer diameter of the tobacco seedlings to be treated as much as possible through the size design of the clamp, and meanwhile, in order to realize stable clamping of the tobacco seedlings and reduce extrusion injury caused by clamping of the tobacco seedlings as much as possible, a sponge layer is stuck to the inner wall of the curved plate and has good air permeability and elasticity, the sponge layer can reduce the hard extrusion operating force of the tobacco seedlings and improve the friction holding force of the tobacco seedlings, and meanwhile, because the outer diameters of the tobacco seedlings cannot be completely consistent, the proper deformation of the sponge layer can improve the clamping adaptability of the clamp to a plurality of tobacco seedlings with the outer diameter numerical value changing within a range.

The completion of a complete operation process of the stock cutting device is based on that the corresponding clamp on the cutting frame and the tobacco seedling part in the clamp are all moved out of the cutting frame. And the cutting frame of the stock cutting device after completing one operation flow resets under the action of the corresponding pushing cylinder, and the next complete operation flow is carried out, namely, feeding and cutting are carried out again.

Meanwhile, the modern industry can ensure the operation stability of the output end of the pushing cylinder as far as possible, and can ensure that the cutting frame only moves horizontally and oppositely to ensure that the clamp clamping block in the slide rail on the cutting frame cannot shake, and the contact between the toggle block and the driving block on the clamping block also ensures that the clamping block is limited in the horizontal direction, so that the clamp clamping block can be ensured not to move along the length direction of the slide rail when moving along with the cutting frame and clamping tobacco seedling stalks, certainly for safety, the contact surface of the limiting slide block on the clamping block or/and the slide rail can be subjected to surface roughness treatment, and the contact friction force between the limiting slide block and the slide rail is reasonably improved on the basis of not influencing the movement of the driving clamping block by a driving belt.

Compared with the prior art, the invention has the following advantages: the invention realizes the industrial operation, ensures that the tobacco seedlings as stock have completely same cuts and effective protection by endowing the tobacco seedlings with strength support and limitation of cutting direction and position during cutting through the clamp, and can completely realize the batch tobacco seedling cutting operation by the mutual cooperative match of all transmission mechanisms. And the cutter is mechanically controlled, the whole working environment is fixed, sterile management can be introduced, and the germ infection rate of the tobacco seedlings caused by cutting is reduced.

The completion of a complete operation process of the stock cutting device is based on that the corresponding clamp on the cutting frame and the tobacco seedling part in the clamp are all moved out of the cutting frame. And the cutting frame of the stock cutting device after completing one operation flow resets under the action of the corresponding pushing cylinder, and the next complete operation flow is carried out, namely, feeding and cutting are carried out again.

Meanwhile, the modern industry can ensure the operation stability of the output end of the pushing cylinder as far as possible, and can ensure that the cutting frame only moves horizontally and oppositely to ensure that the clamp clamping block in the slide rail on the cutting frame cannot shake, and the contact between the toggle block and the driving block on the clamping block also ensures that the clamping block is limited in the horizontal direction, so that the clamp clamping block can be ensured not to move along the length direction of the slide rail when moving along with the cutting frame and clamping tobacco seedling stalks, certainly for safety, the contact surface of the limiting slide block on the clamping block or/and the slide rail can be subjected to surface roughness treatment, and the contact friction force between the limiting slide block and the slide rail is reasonably improved on the basis of not influencing the movement of the driving clamping block by a driving belt.
