Description

Technical Field

[0001] The present invention relates to the technical field of nursery stock grafting, and particularly to a grafting device and a grafting method for landscaping nursery stocks. Background Art

[0002] With the acceleration of the urbanization process and people's emphasis on the ecological environment, landscaping has become increasingly prominent in urban construction. As the basic material for landscaping, the variety improvement and quality enhancement of nursery stocks have become the key to the development of the industry. As an efficient means of nursery stock propagation and improvement, grafting technology is widely used in landscaping, fruit tree cultivation, and forestry production.

[0003] Grafting is a technique that combines the tissues of two different plants and enables them to heal and grow into a new plant. The traditional grafting process includes steps such as incision making, grafting fixation, and binding. These steps require high technical skills from the operator. Moreover, when the operator makes the incision, it is easy to cause inconsistencies in the length, shape, etc. of the incisions on the two nursery stocks, resulting in the inability to accurately dock the two nursery stocks, affecting the grafting quality. At the same time, the efficiency of manual grafting is low, and it is difficult to achieve large-scale production. Summary of the Invention

The glue liquid in the glue storage space is discharged through the gap between the sealing edge and the bottom of the groove plate. A feeding pipe for supplying glue liquid into the glue storage space is provided on the support plate.

[0014] In some embodiments of the present invention, the conveying unit further includes a clamping unit for fixing the seedlings. The clamping unit includes a first arc plate and a second arc plate.

[0044] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0045] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the technical field to which this invention belongs. The terms used in the description of this invention are for the purpose of describing specific embodiments only and are not intended to limit the invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0046] As Figures 1 to 3 shown, a grafting device for landscaping nursery stock of the present invention includes two sets of conveying units 100 distributed relatively, a cutting unit 200 located between the two conveying units 100 and used for cutting two grafted nursery stocks, and a bandaging unit 300 used for hermetically bandaging two butt-jointed nursery stocks.

[0047] The two conveying units 100 are respectively used for conveying two grafted nursery stocks. The conveying unit 100 includes a moving table 101, a guiding groove 102 opened on the moving table 101, a sliding column 103 slidably located in the guiding groove 102, and a moving seat 104 installed at the end of the sliding column 103. The shape of the guiding groove 102 is Z-shaped. The nursery stock is fixed on the moving seat 104, and the moving seat 104 moves along the track of the guiding groove 102.

[0048] Wherein, the distance between the conveying unit 100 and the cutting unit 200 is adjustable.

[0049] In the present invention, the two sets of conveying units 100 can be distributed relatively in the horizontal direction or the vertical direction. When a relatively small nursery stock is grafted onto a relatively large nursery stock, the vertical distribution mode can be adopted, and the relatively large nursery stock is located on the lower conveying unit 100. When the volumes of the two nursery stocks are both small, the horizontal distribution form can be adopted. As Figure 1 shown, taking the horizontal direction as an example, the two sets of conveying units 100 are distributed left and right. It can realize the conveying work of the two sets of nursery stocks in the longitudinal direction, that is, the conveying unit 100 will convey the nursery stock backward to the position of the cutting unit 200, and then convey it to the position of the bandaging unit 300, thereby realizing the conveying work of the nursery stock between different workstations. The cutting unit 200 can perform cutting treatment on the end of the nursery stock to make the end of the nursery stock form a cut with a specified shape, which is convenient for subsequent grafting, and the shape of the cut can be Figure 10 the Z shape in Figure 11 the bow shape in Figure 12The tooth shape in [description], of course, in some embodiments, the incision can also be any shape such as an arc shape, a wedge shape, a V shape, etc. As long as it can achieve the purpose of increasing the contact area and improving the survival rate, it is within the protection scope of this case; the cutting unit 200 can adopt methods such as scissor cutting and extrusion cutting; the bandaging unit 300 can hermetically bandage the docking position of the two seedlings that have been cut and docked together, so as to avoid air leakage or damage to the incision position by bacteria and viruses. For the specific bandaging method of the bandaging unit 300, it can adopt methods such as film winding, docking and clamping with two arc-shaped sealing sleeves, or glue application. As long as it can achieve the insect protection effect, it is within the protection scope of this case;

[0050] It should be noted that the moving platform 101 on the conveying unit 100 is mainly used to support structures such as the sliding columns 103 and the moving seats 104 thereon. Since the cutting unit 200 needs to cut the seedlings and the two groups of seedlings need to be docked, the distance between the two groups of conveying units 100 needs to be adjustable, that is, the distance between the conveying unit 100 and the cutting unit 200 is adjustable, so as to be able to push the seedlings to the position of the cutting unit 200 or dock the two seedlings. Specifically, a bottom plate 119 can be set so that the two moving platforms 101 are both slidably installed on the bottom plate 119, and the cutting unit 200 and the bandaging unit 300 are both fixed on the bottom plate 119. A number of push-pull structures 120 are configured on each moving platform 101, and the push-pull structures 120 are fixed on the bottom plate 119. In this way, the push-pull structures 120 can be used to push the moving platform 101 to move, so as to adjust the position of the seedlings. Of course, other structures such as motors, threaded rods, and oil cylinders can also be used to provide power for the movement of the moving platform 101;

[0051] Since the shape of the guide groove 102 is Z-shaped, the two horizontal sides of the Z-shape can correspond to the cutting unit 200 and the bandaging unit 300, and the inclined side of the Z-shape can achieve the transition between the two horizontal sides. Due to the obstruction of the cutting unit 200, the distance between the two seedlings at the position of the cutting unit 200 is relatively far, while at the position of the bandaging unit 300, since the two seedlings need to be docked, the distance between the two seedlings is relatively close. The Z-shaped design of the guide groove 102 can meet the above requirements;

[0052] During use, two seedlings to be grafted are respectively fixed on two moving seats 104. The sliding column 103 is pushed to move along the trajectory of the guiding groove 102. When the two moving seats 104 move to the position of the cutting unit 200, the moving seat 104 is located on a horizontal side of the Z-shape where the guiding groove 102 is located. At this time, the distance between the two moving seats 104 is relatively far. The two moving platforms 101 are pushed to move closer to each other synchronously. The moving seat 104 moves and brings the end parts of the seedlings close to the cutting unit 200. The cutting unit 200 simultaneously cuts the end parts of the two seedlings on the left and right sides, so as to form incisions with the same shape and size at the end parts of the two seedlings. After the seedlings are cut, the two moving platforms 101 are reset. Then, the sliding column 103 is continuously pushed to move. When the moving seat 104 moves to the position of the bandaging unit 300, the moving seat 104 is located on the other horizontal side of the Z-shape where the guiding groove 102 is located. At this time, the distance between the two moving seats 104 is relatively close. The two moving platforms 101 are pushed to move closer to each other. The two seedlings are butted against each other. The bandaging unit 300 is used to seal and bandage the butting position of the seedlings, thus completing the grafting work of the seedlings. The seedlings can be taken down; after the seedlings are taken down, the moving seat 104 is reset and the next grafting work is carried out;

[0053] It can be seen that when the seedlings are conveyed, they only need to meet the movement at specific positions. Therefore, other methods such as a circulating conveyor belt can also be used to convey the seedlings, and it is coordinated with the adjustment work of the seedlings in the horizontal position. Of course, the number of the moving seats 104 can also be set to multiple, so as to realize the continuous conveying and grafting work of the seedlings, which can further improve the efficiency;

[0054] By adopting the cooperation mode of the conveying unit 100, the cutting unit 200 and the bandaging unit 300, the automatic conveying, cutting, grafting, bandaging and other work of the seedlings are realized, reducing the manual operation steps, significantly improving the grafting efficiency, and the device supports continuous operation, reducing the intermediate pause time, which is suitable for large-scale production; the cutting unit 200 can simultaneously cut two seedlings, ensuring that the incision shapes and sizes are consistent, and avoiding the problem of inconsistent incisions caused by technical differences in manual operation; by using the Z-shaped guiding groove 102, the seedlings can smoothly realize cutting and butting work at the cutting unit 200 and the bandaging unit 300, which is convenient for accurately controlling the position of the seedlings.

[0055] Optimized based on the above implementation, the cutting unit 200 cuts the seedlings by grinding.

[0056] When processing the cut of seedlings, if traditional methods such as extrusion cutting and scissor cutting are used, they will all exert a downward pressure on the seedlings, resulting in the seedlings being crushed by the force, which will cause the deformation of the end of the seedlings and damage them, affecting the subsequent docking work. By using the grinding method, the force deformation of the end of the seedlings can be reduced. While protecting the seedlings, the cut can be formed quickly and accurately, thus facilitating the accurate docking of the subsequent seedlings; The grinding method adopted by the cutting unit 200 can be any method such as high-speed rotation cutting of the blade and scraping of the edge of the wheel disc. As long as it can process the port of the seedling into a specified shape and protect the seedling from damage, it is within the protection scope of this case.

[0057] Optimized based on the above implementation, such as Figure 6 As shown, the cutting unit 200 includes a large grinding wheel 201 and a small grinding wheel 202, and the large grinding wheel 201 and the small grinding wheel 202 rotate coaxially in opposite directions.

[0058] In this case, the large grinding wheel 201 and the small grinding wheel 202 rotate coaxially, and there is a difference in the diameters of the large grinding wheel 201 and the small grinding wheel 202. In this way, when the end of the seedling moves laterally towards the outer walls of the large grinding wheel 201 and the small grinding wheel 202, both the large grinding wheel 201 and the small grinding wheel 202 can grind and cut the end of the seedling. And due to the diameter difference between the large grinding wheel 201 and the small grinding wheel 202, a cut with a specified shape can be formed at the end of the seedling. The shape of this cut is as Figure 10 shown. In this way, when two seedlings are docked, they can have a larger docking area and stronger connection firmness;

[0059] Since both the large grinding wheel 201 and the small grinding wheel 202 will grind and cut the end of the seedling, when the large grinding wheel 201 and the small grinding wheel 202 rotate in the same direction, the forces exerted by the large grinding wheel 201 and the small grinding wheel 202 on the end of the seedling will overlap, thus increasing the force on the end of the seedling. The seedling is prone to bending due to friction. When the large grinding wheel 201 and the small grinding wheel 202 rotate in opposite directions, their forces on the seedling can cancel each other out in part, thereby reducing the force on the seedling and facilitating the seedling to maintain a straight state;

[0060] It should be noted that to achieve the synchronous reverse rotation mode of the large grinding wheel 201 and the small grinding wheel 202, methods such as Figures 5 to 6In this way, the cutting unit 200 further includes a support base 203 and support columns 204 mounted on the large grinding wheel 201 and the small grinding wheel 202. The support columns 204 are fixed on the support base 203, and the large grinding wheel 201 and the small grinding wheel 202 rotate on the corresponding support columns 204. A part of the support column 204 is inserted into the corresponding large grinding wheel 201 or small grinding wheel 202. A connecting rod 205, a number of transmission wheels 206 and two connecting rings 207 are arranged between the two support columns 204. The connecting rod 205 connects the two support columns 204. A number of transmission wheels 206 are all rotatably mounted on the connecting rod 205. The two connecting rings 207 are respectively mounted on the inner walls of the large grinding wheel 201 and the small grinding wheel 202, and the transmission wheels 206 are located between the two connecting rings 207. The transmission wheels 206 are in transmission connection with the connecting rings 207. In this way, when the large grinding wheel 201 rotates, it will drive the small grinding wheel 202 to rotate through the two connecting rings 207 and a number of transmission wheels 206, and the large grinding wheel 201 and the small grinding wheel 202 rotate synchronously and in opposite directions. The support base 203 and the support columns 204 can be used to support the large grinding wheel 201 and the small grinding wheel 202. Of course, the small grinding wheel 202 can also be rotated to drive the large grinding wheel 201 to rotate; A sub-motor 210 and a driving wheel 211 can be arranged on the support base 203. By using the transmission connection relationship between the driving wheel 211 and the large grinding wheel 201 or the small grinding wheel 202, the sub-motor 210 drives the large grinding wheel 201 or the small grinding wheel 202 to rotate through the driving wheel 211; A transmission ring cooperating with the driving wheel 211 can also be arranged on the large grinding wheel 201 or the small grinding wheel 202 to achieve power transmission;

[0061] Since debris will be generated when the seedlings are cut, a number of inclined openings 208 can be opened on both the large grinding wheel 201 and the small grinding wheel 202, and the directions of the inclined openings 208 on the large grinding wheel 201 and the small grinding wheel 202 are opposite. A wind guide plate 209 is arranged on the support base 203. When the large grinding wheel 201 and the small grinding wheel 202 rotate, the inclined openings 208 can be used to push the air to flow. When the air blows to the wind guide plate 209, it diffuses to the outer periphery, so that the air flow blows to the seedlings and cleans the debris. Of course, the specific shape and installation position of the wind guide plate 209 can be determined according to the actual situation and are not limited here.

[0062] Optimized based on the above implementation, cutter teeth with a planing tooth shape are arranged on the outer walls of both the large grinding wheel 201 and the small grinding wheel 202.

[0063] When using the large grinding wheel 201 and the small grinding wheel 202 to grind the ends of the seedlings, if the circumferential outer walls of the large grinding wheel 201 and the small grinding wheel 202 are directly used, the grinding amount each time is less and the working efficiency is low. To improve the efficiency, planing teeth can be installed on the outer walls of both the large grinding wheel 201 and the small grinding wheel 202. By using the scraping effect of the planing teeth on the ends of the seedlings, the end cuts of the seedlings can be quickly formed.

[0064] Optimized based on the above implementation, the wrapping unit 300 wraps the grafted seedlings in a way of being wrapped with soft glue.

[0065] In the present invention, the soft glue can be applied to the seedling grafting position, and the soft glue will form a protective layer at the grafting position, thereby achieving a sealing effect. When the soft glue solidifies, the protective layer is shaped. This method can improve the sealing effect, simplify the wrapping method, and facilitate wrapping of irregular grafting positions;

[0066] In actual use, the soft glue can be silicone sealant, which has good elasticity and waterproofness, and can adapt to the growth and expansion of trees after curing, is non-toxic to plants, and has high safety; white glue, which is non-toxic, environmentally friendly, low in price, and easy to obtain, but it is relatively hard after curing and lacks elasticity, so it can be used for specific seedlings; rubber cement, which has good elasticity and waterproofness; cyanoacrylate glue, which has a fast curing speed and can quickly fix the grafting part; in some embodiments, a wax sealing method can also be selected, but this method will cause damage to the seedlings due to high temperature, so wax sealing can only be applicable to some seedlings.

[0067] Optimized based on the above implementation, as Figure 7 shown, the wrapping unit 300 includes a support plate 301, a groove plate 302 installed on the support plate 301, and a pressing plate 303 slidably located inside the groove plate 302. The pressing plate 303 and the groove plate 302 are connected by an elastic body 304. The pressing plate 303 and the groove plate 302 form a glue storage space. A sealing edge 305 is provided at the bottom of the side wall of the pressing plate 303 facing the glue storage space. The glue liquid in the glue storage space is discharged through the gap between the sealing edge 305 and the bottom of the groove plate 302. A feeding pipe 306 for supplying glue liquid into the glue storage space is provided on the support plate 301.

[0068] In the present invention, the support plate 301 is relatively fixed and used to support the structures thereon. The groove plate 302 and the pressing plate 303 form a trough-shaped structure with an opening facing downwards, and its opening is long strip-shaped. The elastic body 304 can provide an elastic thrust to the pressing plate 303, so that the sealing edge 305 is in close contact with the inner wall of the groove plate 302, and the glue storage space is sealed. When the glue liquid is introduced into the glue storage space through the feeding pipe 306, the glue liquid pressure will push the pressing plate 303 and the sealing edge 305 to move, and the glue liquid will be discharged downward through the gap between the sealing edge 305 and the side wall of the groove plate 302, and the discharged glue liquid is in a sheet shape, so that it is convenient for the glue liquid to adhere to the seedling grafting position; it should be noted that during wrapping, the seedlings can rotate, so that the sheet-shaped glue liquid adheres to the grafting position evenly and comprehensively; to prevent the glue liquid from dripping randomly, a brush or a smoothing structure can also be provided on the support plate 301 to evenly apply the glue liquid;

[0069] With the above structure, when the glue supply stops, the elastomer 304 can push the pressing plate 303 to reset, the sealing edge 305 fits against the side wall of the groove plate 302 again, and the glue storage space is sealed again.

[0070] Optimized based on the above implementation, such as Figures 8 to 9 As shown, the conveying unit 100 further includes a clamping unit for fixing the seedlings. The clamping unit includes a first arc plate 105 and a second arc plate 106. The first arc plate 105 and the second arc plate 106 form a cylinder, and at least part of the cylinder is connected to the moving seat 104. The cylinder rotates on the moving seat 104. The first arc plate 105 and the second arc plate 106 are slidably connected through a guide post 107. One end of either the first arc plate 105 or the second arc plate 106 is provided with a gear 108. A rack 109 that cooperates with the gear 108 is provided on the moving table 101, and the shape of the rack 109 is the same as the shape of the guide groove 102;

[0071] Among them, the diameters of the two gears 108 on the two conveying units 100 are not equal, and the cylinder is used to fix the seedlings.

[0072] In the present invention, the cylinder formed by the first arc plate 105 and the second arc plate 106 can fix the seedlings. That is, when fixing the seedlings, first open the first arc plate 105 or the second arc plate 106, put the seedlings into the cylinder, and then close the first arc plate 105 or the second arc plate 106, so as to realize the extrusion and fixing work of the seedlings. Multiple guide posts 107 can be provided, and they are mainly used to connect and guide the first arc plate 105 and the second arc plate 106; in some special cases, when the root of the seedling is relatively large, the root of the seedling can be exposed outside the gear 108, and a round hole is opened in the middle of the gear 108, so that the end of the seedling passes through the round hole and is inserted into the cylinder;

[0073] Since when the cutting unit 200 cuts two seedlings, the cut shapes of the two cut seedlings are the same and they are symmetric left and right, it is impossible to perform the docking work. One seedling needs to be relatively fixed, and the other seedling needs to be flipped 180°. Only in this way can the cuts of the two seedlings be staggered and corresponding, and the two seedlings can be normally docked. To achieve this purpose, the way that the moving seat 104 drives the gear 108 to move on the fixed rack 109 can be used, so that the gear 108 drives the cylinder and the seedlings therein to rotate, thereby realizing the work of adjusting the angle of the seedlings. Since the diameters of the two gears 108 are not equal, when the two moving seats 104 move synchronously, the rotation angles of the two seedlings are not equal, so that the relative positions of the two seedlings can be adjusted;

[0074] It should be noted that since the cylinder formed by the first arc plate 105 and the second arc plate 106 can rotate on the moving seat 104 and one of the first arc plate 105 or the second arc plate 106 needs to be able to open and move away from the moving seat 104, a plurality of guide columns 107 can be used to keep the first arc plate 105 and the second arc plate 106 in a connected relationship. When the first arc plate 105 and the second arc plate 106 are closed, they form a cylindrical shape and can rotate normally on the moving seat 104. When one of the first arc plate 105 or the second arc plate 106 moves outside the moving seat 104, it can be allowed to separate from the moving seat 104; specifically, one end of the guide column 107 is fixed on the second arc plate 106, and the other end of the guide column 107 is slidably installed on the first arc plate 105; to realize the opening and closing of the cylinder, two outer rings 111 can be sleeved outside the cylinder. Each outer ring 111 is rotatably connected to the second arc plate 106 through a connecting plate 112. The outer ring 111 is coaxial with the cylinder. A moving ring 113 is rotatably sleeved on the outer wall of the outer ring 111. Adjusting cylinders 114 are arranged on the front and rear side walls of the moving seat 104. The adjusting cylinders 114 are slidably installed on the moving seat 104, and the movable end of the adjusting cylinder 114 is connected to the outer wall of a sliding column 103, and the fixed end of the adjusting cylinder 114 is connected to the outer wall of the other moving ring 113. In this way, when the moving ring 113 expands and contracts, it can push the two moving rings 113 away from or close to each other. The moving ring 113 drives the second arc plate 106 to move away from or close to the moving seat 104 through the connecting plate 112 and the outer ring 111, thereby controlling the opening or closing of the cylinder. When the cylinder rotates, the second arc plate 106 will drive the outer ring 111 to rotate on the moving ring 113 through the connecting plate 112, so that it will not interfere with the rotation of the cylinder and is convenient for installing the adjusting cylinder 114 to avoid the adjusting cylinder 114 rotating with the cylinder; since the guiding function between the second arc plate 106 and the first arc plate 105 is realized through the guide column 107, the second arc plate 106 can only move smoothly, so the two connecting plates 112 are only allowed to move synchronously, thereby realizing the purpose of the adjusting cylinder 114 pushing the two moving rings 113 to move synchronously in the opposite direction, and the adjusting cylinder 114 is allowed to move on the moving seat 104.

[0075] Optimized based on the above implementation, the rack 109 slides on the moving table 101, and a power cylinder 110 for adjusting the position of the rack 109 is arranged on the moving table 101, and the two power cylinders 110 perform differential motion.

[0076] Since the seedlings need to be rotated at the bandaging unit 300 so that the glue can fully adhere to the grafting position of the seedlings, the gear 108 needs to be rotated. At this time, the movement of the rack 109 can be controlled by the telescopic movement of the power cylinder 110. The rack 109 pushes the gear 108 to rotate. If the two power cylinders 110 move at the same speed, the rotation speeds of the two seedlings will be inconsistent, which will cause the grafting position to be distorted and deformed. To avoid this phenomenon, the two power cylinders 110 need to perform differential movement to ensure that the two gears 108 rotate at the same angular velocity and the two seedlings rotate synchronously.

[0077] Optimized based on the above implementation, as Figure 4 shown, a power unit for providing power for the movement of the moving seat 104 is provided on the moving table 101. The power unit includes a main motor 115 installed on the moving table 101, a lead screw 116 installed on the output end of the main motor 115, and a moving sleeve 117 slidably installed on the moving table 101. The lead screw 116 passes through the moving sleeve 117 and is threadedly connected to each other. An insertion plate 118 is slidably inserted through the moving sleeve 117, and the insertion plate 118 is fixedly connected to the sliding column 103.

[0078] In the present invention, the sliding direction of the insertion plate 118 on the moving sleeve 117 is perpendicular to the length direction of the lead screw 116. The main motor 115 can push the moving sleeve 117 to move through the lead screw 116. The moving sleeve 117 pushes the sliding column 103 to move through the insertion plate 118, so that the sliding column 103 moves along the trajectory of the guiding groove 102. Since the distance between the sliding column 103 and the moving sleeve 117 will change, the insertion plate 118 needs to slide on the moving sleeve 117. In addition, to prevent the direction of the moving seat 104 from changing when it moves, the insertion plate 118 is needed to limit its direction.

[0079] A method for grafting landscaping seedlings includes the following steps:

[0080] Fix the two seedlings to be grafted on two groups of conveying units 100 respectively;

[0081] The two groups of conveying units 100 carry the seedlings and move to the position of the cutting unit 200;

[0082] The cutting unit 200 cuts the ends of the seedlings so that the ends of the seedlings form the incision shape required for grafting;

[0083] Use the two groups of cutting units 200 to move the seedlings to the position of the bandaging unit 300;

[0084] Dock the two cut seedlings and use the bandaging unit 300 to seal and bandage the docking position;

[0085] Remove the bandaged seedlings, and the grafting work of the seedlings can be completed.

[0086] Through automated, precise, and modular design, this method significantly improves the grafting efficiency, success rate, and survival rate of seedlings. Meanwhile, it reduces manual operations and seedling damage, has strong adaptability, is easy to operate, suitable for large-scale production, and has remarkable practicality and economy.
