Description

Technical Field

[0002] A grafted rootstock refers to the plant or plant part that bears the scion in grafting reproduction. The rootstock has a developed root system that can fix the plant, absorb water and nutrients from the soil, and provide the necessary material basis for the growth of the scion. When grafting Solanaceae vegetables, the rootstock and the branches of the Solanaceae need to be cut into an inclined shape, and the two inclined surfaces need to fit together perfectly. During use, the existing rootstock cutting device needs to cut the rootstock and the branches of the Solanaceae in sequence, which makes it impossible to keep the inclination angle of the cross-section consistent after cutting, and thus the two cross-sections cannot fit together perfectly, which makes it difficult to align the cambium, resulting in healing difficulties, affecting the conduction of nutrients and water, thereby reducing the survival rate of the grafted seedlings, and after the cutting is completed, the two cross-sections cannot fit together immediately, resulting in water loss and contamination of the cross-sections, reducing cell activity, and making it impossible for the cambium of the two branches to be better aligned and healed, affecting the success rate of the grafting.

DETAILED DESCRIPTION

[0028] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0029] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0031] Example 1 Reference Figure 1-Figure 5 , which is the first embodiment of the present invention, and this embodiment provides a grafted rootstock seedling cutting device. The grafted rootstock seedling cutting device includes a fixing assembly 100, including a fixing frame 101. The fixing frame 101 is U-shaped and is used to carry the entire device. A clamping plate 102 is arranged on the inner side of the fixing frame 101. The clamping plates 102 are arc-shaped, and there are four of them. Two clamping plates 102 are located in a group above and below the inner side of the fixing frame 101 respectively. In the initial state, the two clamping plates 102 are in an outwardly opened state. The clamping plates 102 are used to clamp and fix the rootstock and Solanaceae vegetable branches and trunks that need to be cut off to prevent the two from moving when cutting, and to enable the two to maintain a coaxial state.

[0032] A stabilizing frame 103 is provided on one side of the splint 102. There are two stabilizing frames 103, which are respectively located above and below the inner side of the fixed frame 101. The two splints 102 are arranged as a group on the stabilizing frame 103. The stabilizing frame 103 can move up and down inside the fixed frame 101. A positioning shaft 104 is fixed inside the splint 102. The number of the positioning shaft 104 is movably connected with the stabilizing frame 103, so as to support and position the splint 102.

[0033] When cutting, the rootstock and the branches of Solanaceae vegetables are placed between the two upper and lower groups of two clamps 102 respectively, and the two ends of the branches are brought into contact. At this time, the clamps 102 can be rotated inward and the branches are clamped and fixed by the clamps 102 to prevent the branches from moving during the cutting process, resulting in the ends of the two branches being unable to align, and the cross-sections of the two branches being misaligned when they are fitted, resulting in a situation where they cannot fit perfectly.

[0034] A first torsion spring 104-1 is fixed to the outside of the positioning shaft 104, and the other end of the first torsion spring 104-1 is fixed to the stabilizing frame 103. When the two branches are cut off and fixed, the first torsion spring 104-1 can drive the positioning shaft 104 and the clamping plate 102 to rotate in the opposite direction and separate the clamping plate 102 from the branches.

[0035] The cutting assembly 200 is arranged on the inner side of the fixed frame 101, and includes a cutting knife 201. The cutting knife 201 is inclined, and there are two of them. A connecting plate 202 is fixed on one side of the cutting knife 201. The two cutting knives 201 are respectively fixed on the upper and lower sides of the connecting plate 202. When the connecting plate 202 moves, it will drive the cutting knife 201 to approach the fixed rootstock and the branches of the Solanaceae vegetables, and cut the two through the cutting knife 201, and make the inclination angle of the cut surface of the two after cutting consistent, so that the two can fit together perfectly when they are fitted, and the cambium can be aligned, so that the two can heal quickly, thereby improving the survival rate of the grafted seedlings.

[0036] A fixed column 203 is fixed on one side of the connecting plate 202, and a rotating sleeve 204 is rotatably connected in the fixed frame 101. A spiral groove 203-1 and a sliding groove 203-2 are provided on the fixed column 203. There are two spiral grooves 203-1 and two sliding grooves 203-2, both of which are located on the outside of the fixed column 203. The sliding groove 203-2 is a straight line, and both ends are connected to the spiral groove 203-1 respectively. A fixed shaft 205 is inserted on the rotating sleeve 204.

[0037] When the rotating sleeve 204 rotates, it will drive the fixed shaft 205 to slide in the spiral groove 203-1. Through the cooperation of the two, the fixed column 203 can drive the connecting plate 202 and the cutting knife 201 to move, so that the cutting knife 201 can cut the branches. When the branches are cut off, the fixed shaft 205 will enter the sliding groove 203-2. At this time, the connecting plate 202 will drive the cutting knife 201 to move in the opposite direction, so that the cutting knife 201 is separated from the cut surface of the branch.

[0038] At the same time, the fixed column 203 moves in the opposite direction, and the fixed shaft 205 slides in the slide groove 203-2, so as not to hinder the resetting of the connecting plate 202 and the cutting knife 201. At this time, the fixed shaft 205 enters the spiral groove 203-1 again. When the rotating sleeve 204 rotates again, the connecting plate 202 and the cutting knife 201 can be moved again.

[0039] When the fixed shaft 205 enters the slide groove 203-2 from the spiral groove 203-1, a blocking bar 203-3 is fixed on the contact path between the two. The blocking bar 203-3 is located on one side of the spiral groove 203-1 and is inclined, so as not to hinder the fixed shaft 205 from moving toward the slide groove 203-2. The other side of the blocking bar 203-3 is in a vertical state. When the fixed column 203 moves in the opposite direction and makes the fixed shaft 205 move in the slide groove 203-2, the moving trajectory of the fixed shaft 205 can be limited so that it can only move in the slide groove 203-2, thereby preventing it from returning to the original path and entering the spiral groove 203-1.

[0040] The pulling assembly 300 is arranged on the inner side of the fixed frame 101, and includes a connecting rod 301 arranged on one side of the stabilizing frame 103. There are two connecting rods 301, which are respectively connected to the two stabilizing frames 103. The ends of the connecting rod 301 are hinged to the stabilizing frames 103 through hinge plates. The two connecting rods 301 are both inclined. The ends of the connecting rods 301 are rotatably connected to connecting columns 302. The connecting rods 301 are used to connect the ends of the two connecting rods 301. A positioning groove 101-1 is opened on the inner side of the fixed frame 101. The connecting column 302 slides in the positioning groove 101-1. The positioning groove 101-1 is used to limit the moving trajectory of the connecting column 302.

[0041] When the cutting knife 201 cuts off the branch and moves in the opposite direction to reset, the connecting column 302 will drive the two connecting rods 301 to move, and the ends of the two connecting rods 301 will drive the upper and lower stabilizing frames 103 to move closer, so that the splint 102 can drive the cut surfaces of the two branches closer and make the two cut surfaces fit together. At this time, the staff can directly fix the two branches together with tape, so as to minimize the time the cut surface is exposed to the air, reduce the possibility of water loss and contamination of the cut surface, maintain cell activity, and enable the cambium of the two branches to be better aligned and healed, thereby improving the success rate of grafting.

[0042] It should be noted that since the rootstock is fixed in the ground, it cannot be moved by the splint 102. Therefore, when the two splints 102 move the branches, the user needs to adaptively move the fixing frame 101 downward as a whole to ensure that the cross-sections of the two branches can fit together.

[0043] Example 2 Reference Figure 2-Figure 10 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0044] Specifically, the fixing assembly 100 also includes an extrusion piece 105, which includes a force-bearing block 105a fixed to one side of the splint 102. The number of the force-bearing blocks 105a corresponds to the splint 102. An extrusion block 105b is arranged on one side of the force-bearing block 105a. One side of the extrusion block 105b is arc-shaped and contacts with two force-bearing blocks 105a. A through groove is provided on one side of the stabilizing frame 103. When the stabilizing frame 103 moves up and down, the extrusion block 105b can slide relatively in the through groove. There are two extrusion blocks 105b, which are respectively located in the through grooves of the upper and lower stabilizing frames 103.

[0045] A fixing rod 105c is fixed to one side of the extrusion block 105b, a connecting frame 105d is sleeved on the outside of the fixing rod 105c, a first spring 105e is fixed to one end of the fixing rod 105c, a positioning rod 105f is fixed to the bottom of the connecting frame 105d, and the positioning rod 105f connects and fixes the upper and lower connecting frames 105d.

[0046] When the positioning rod 105f moves, it will drive the connecting frame 105d to move. The connecting frame 105d pushes the fixing rod 105c and the squeezing block 105b to move through the first spring 105e, and makes the squeezing block 105b squeeze the two force blocks 105a, so that the clamping plate 102 can be driven to rotate through the force blocks 105a, and then the clamping plate 102 can clamp and fix the branches.

[0047] When the clamping plate 102 completes clamping the branch and cannot continue to rotate, the positioning rod 105f and the connecting frame 105d are still moving, and the first spring 105e will be compressed without hindering the normal movement of the positioning rod 105f.

[0048] Specifically, the cutting assembly 200 includes a pushing member 206, which includes a rotating rod 206a sleeved on the outer side of the rotating sleeve 204, the rotating rod 206a is movably connected to the outer side of the rotating sleeve 204, a clamping block 206b is inserted on the rotating rod 206a, one side of the clamping block 206b is inclined, and a clamping slot 204-1 is opened on the rotating sleeve 204. There are multiple clamping slots 204-1, which are evenly distributed in a ring shape on the outer side of the rotating sleeve 204. Through the provision of multiple clamping slots 204-1, the rotating rod 206a can be rotated to any angle, and the clamping block 206b can be engaged with the clamping slot 204-1. The rotating rod 206a is connected to the rotating sleeve 204 through the cooperation of the two, so that when the rotating rod 206a is initially rotated, it will drive the rotating sleeve 204 to rotate, and when the rotating rod 206a is reversely rotated and reset, it will not drive the rotating sleeve 204 to rotate.

[0049] A mounting frame is fixed on one side of the rotating rod 206a, and the clamping block 206b is movably connected to the mounting frame. A seventh spring is fixed on one side of the clamping block 206b, and the seventh spring is used to apply a thrust to the clamping block 206b so that the clamping block 206b and the clamping slot 204-1 are more tightly engaged.

[0050] A movable sleeve 206c is sleeved on the outer side of the rotating rod 206a, and the movable sleeve 206c is movably connected to the outer side of the rotating rod 206a. A moving rod 206d is arranged on one side of the movable sleeve 206c. The moving rod 206d is hinged to the movable sleeve 206c through a hinge plate. The other end of the moving rod 206d passes through the outside of the fixed frame 101 and is fixed with a force-bearing rod 206e. A push column 206f is fixed on one side of the positioning rod 105f. The push column 206f is short in length and does not contact the force-bearing rod 206e in the initial state.

[0051] When the positioning rod 105f moves a certain distance and the clamping plate 102 completes clamping the branch, the push column 206f will contact the force-bearing rod 206e and push the force-bearing rod 206e to move, so that the force-bearing rod 206e drives the positioning rod 105f to move, so that the positioning rod 105f can drive the rotating rod 206a to rotate, and drive the rotating sleeve 204 to rotate through the rotating rod 206a.

[0052] Specifically, the pulling assembly 300 also includes a pulling member 303, which includes a support rod 303a fixed to one side of the connecting plate 202, a push block 303b is arranged at the end of the support rod 303a, the push block 303b is hollow, a stabilizing shaft is fixed to the inner side below, the stabilizing shaft is movably connected to the support rod 303a, and is used to support and position the push block 303b, a second torsion spring is fixed to the outer side of the stabilizing shaft, and the other end of the second torsion spring is fixed to the support rod 303a, a stop block 303c is arranged on one side of the push block 303b, and the stop block 303c is in contact with the push block 303b, and is used to limit the rotation of the push block 303b.

[0053] When the connecting plate 202 drives the cutting knife 201 to cut the stock, it will simultaneously drive the push block 303b to approach the connecting column 302 through the support rod 303a. When the push block 303b contacts the connecting column 302, it will rotate due to the reverse thrust of the connecting column 302. As the support rod 303a continues to move, the push block 303b will move to the other side of the connecting column 302 and be rotated to a vertical state through the second torsion spring.

[0054] When the connecting plate 202 moves back to its original position, the push block 303b will contact the connecting column 302 again. At this time, the push block 303b is restricted by the stop block 303c, so that the push block 303b cannot rotate, thereby driving the connecting column 302 to move, so that the connecting column 302 can drive the connecting rod 301 to move, and the splint 102 can drive the two branches closer.

[0055] A movable column 303d is fixed to one side of the stopper 303c, one end of the movable column 303d passes through the outside of the fixed frame 101 and is movably connected to the fixed frame 101, a fixed ring is fixed to the top of the support rod 303a, the movable column 303d is movably connected to the inside of the fixed ring, and the two fit tightly, so that when the push block 303b is subjected to a thrust, the stopper 303c will not move due to the thrust of the push block 303b, but can continue to limit the push block 303b.

[0056] When the branches are tied and fixed, the user can push the movable column 303d to drive the stopper 303c to move, so that the stopper 303c is separated from the push block 303b, thereby releasing the restriction on the push block 303b, and allowing the push block 303b to release the restriction on the connecting column 302, so that the connecting column 302 can move in the opposite direction and reset, and the upper and lower stabilizing frames 103 can be reset.

[0057] Specifically, a connecting sleeve 106 is fixed to one side of the fixed frame 101, and both ends of the positioning rod 105f pass through the connecting sleeve 106 and are movably connected to the connecting sleeve 106. A handle 107 is fixed to the bottom of the connecting sleeve 106, and the handle 107 is convenient for the user to hold and use. A movable column 108 is inserted in the connecting sleeve 106, and one end of the movable column 108 is fixed to the positioning rod 105f. During use, the user holds the handle 107 and then pushes the movable column 108 to drive the positioning rod 105f to move. With the movement of the positioning rod 105f, the branches can be clamped, fixed, cut, and the cut surfaces of the branches can be fitted together. The operation is convenient, thereby improving the efficiency of grafting.

[0058] The movable column 108 is tightly connected to the connecting sleeve 106. After use, the movable column 108 can be pulled out.

[0059] Specifically, a mounting rod 202-1 is fixed on one side of the connecting plate 202. There are four mounting rods 202-1, which are respectively fixed on the top and bottom of both sides of the connecting plate 202. Elastic ropes 202-2 are fixed on the ends of the mounting rods 202-1. There are two elastic ropes 202-2, and both ends are respectively fixed to the two mounting rods 202-1 on both sides. The elastic rope 202-2 is elastic. When the cutting knife 201 cuts the branches, the elastic rope 202-2 will contact the branches and bend due to the reverse thrust of the branches. When the branches are cut off, the elastic force of the elastic rope 202-2 can push the cut branches to move and make them fall downward, so that the cut surfaces of the rootstock and the branches of Solanaceae vegetables are exposed and the two can be fitted together. By setting the two elastic ropes 202-2, the rootstock and the branches of Solanaceae vegetables can be pushed away after the branches are cut off.

[0060] Example 3 Reference Figure 1-Figure 11 , which is the third embodiment of the present invention, and is based on the first two embodiments.

[0061] Specifically, a fixed sleeve 205-1 is fixed on one side of the rotating sleeve 204, and the fixed shaft 205 is movably connected with the fixed sleeve 205-1. When the fixed shaft 205 contacts the inclined surface of the baffle bar, it can move into the fixed sleeve 205-1 and pass over the baffle bar. A second spring 205-2 is fixed on one side of the fixed shaft 205, and the other end of the second spring 205-2 is fixed to the inner wall of the fixed sleeve 205-1. The second spring 205-2 is used to apply thrust to the fixed shaft 205, so that the fixed shaft 205 fits more tightly with the spiral groove 203-1 or the slide groove 203-2.

[0062] Specifically, a stabilizing column 103-1 is fixed on the stabilizing frame 103, and a stabilizing sleeve 103-2 is fixed on the inner side of the fixed frame 101. The stabilizing column 103-1 is movably connected with the stabilizing sleeve 103-2, and the two cooperate to support and position the stabilizing frame 103. A third spring 103-3 is fixed to the end of the stabilizing column 103-1, and the other end of the third spring 103-3 is fixed to the inner wall of the stabilizing sleeve 103-2. The third spring 103-3 is used to apply a pulling force to the stabilizing column 103-1, so that the stabilizing frame 103 can be reset after moving. There are four of the above structures, which are respectively located on both sides of the two stabilizing frames 103.

[0063] Specifically, a limiting column 202-3 is fixed on one side of the connecting plate 202, and the other end of the limiting column 202-3 passes through the outside of the fixed frame 101 and is movably connected to the fixed frame 101. There are two limiting columns 202-3, which are respectively fixed at both ends of one side of the connecting plate 202, and are used to limit the movement of the connecting plate 202 to prevent it from offset during movement.

[0064] A fourth spring 202-4 is fixed to one side of the connecting plate 202, and the other end of the fourth spring 202-4 is fixed to the connecting plate 202. When the cutting knife 201 cuts off the rootstock and branches of Solanaceae vegetables, and the fixed shaft 205 enters the slide groove 203-2, the fourth spring 202-4 can pull the connecting plate 202 to move in the opposite direction and reset.

[0065] The elastic force of the fourth spring 202-4 is greater than that of the third spring 103-3, thereby ensuring that when the connecting plate 202 moves in the reverse direction to reset, the push block 303b can drive the connecting column 302 to move and bring the two branches closer together.

[0066] Specifically, a support column 206e-1 is fixed on one side of the fixed frame 101, and the support column 206e-1 is movably connected to the load-bearing rod 206e. There are multiple support columns 206e-1, which are evenly distributed in a straight line on one side of the fixed frame 101, and are used to support and position the load-bearing rod 206e to prevent it from tilting during movement.

[0067] A fifth spring 206e-2 is fixed to one side of the force-bearing rod 206e, and the other end of the fifth spring 206e-2 is fixed to the fixed frame 101. When the push column 206f is separated from the force-bearing rod 206e, the fifth spring 206e-2 can push the force-bearing rod 206e and the moving rod 206d to reset, and make the rotating rod 206a rotate in the opposite direction to reset.

[0068] When in use, the rootstock and the branches of Solanaceae vegetables are respectively placed between the two clamps 102 of the upper and lower groups, and the ends of the two branches are made to contact. At this time, the movable column 108 is pushed to drive the positioning rod 105f to move. When the positioning rod 105f moves, it will drive the connecting frame 105d to move. The connecting frame 105d pushes the fixing rod 105c and the squeezing block 105b to move through the first spring 105e, and the squeezing block 105b squeezes the two force blocks 105a, so that the clamp 102 can be driven to rotate by the force block 105a, and the branches are clamped and fixed by the clamp 102, so as to avoid the movement of the branches during the cutting process, resulting in the inability to align the ends of the two branches, and then the cross-sections of the two branches will be misaligned when they are fitted, resulting in a situation where they cannot fit perfectly.

[0069] As the positioning rod 105f continues to move, the push column 206f will be driven to contact the force-bearing rod 206e, and push the force-bearing rod 206e to move, so that the force-bearing rod 206e drives the positioning rod 105f to move, so that the positioning rod 105f can drive the rotating rod 206a to rotate, and drive the rotating sleeve 204 to rotate through the rotating rod 206a. When the rotating sleeve 204 rotates, it will drive the fixed shaft 205 to slide in the spiral groove 203-1. Through the cooperation of the two, the fixed column 203 can drive the connecting plate 202 and the cutting knife 201 to move, so that the cutting knife 201 can cut the branches. When the branches are cut off, the fixed shaft 205 will enter the sliding groove 203-2. At this time, the connecting plate 202 will drive the cutting knife 201 to move in the opposite direction, so that the cutting knife 201 is separated from the cut surface of the branch.

[0070] When the cutting knife 201 cuts off the branch and moves in the opposite direction to reset, the connecting column 302 will drive the two connecting rods 301 to move, and the ends of the two connecting rods 301 will drive the upper and lower stabilizing frames 103 to move closer, so that the splint 102 can drive the cut surfaces of the two branches closer and make the two cut surfaces fit together. At this time, the staff can directly fix the two branches together with tape, so as to minimize the time the cut surface is exposed to the air, reduce the possibility of water loss and contamination of the cut surface, maintain cell activity, and enable the cambium of the two branches to be better aligned and healed, thereby improving the success rate of grafting.
