Description

Technical Field

[0001] The present invention relates to the technical field of grape grafting, and particularly relates to an adjustable grape rootstock grafting clamp. Background Art

[0002] Grafting is one of the methods of asexual propagation of seedlings, that is, taking a branch or bud from a plant of an excellent variety and connecting it to an appropriate part of another plant, so that the two are combined to generate a new plant. In the actual process of grape cultivation, in order to improve the taste and nutritional value of grapes, different varieties of grapes are often grafted; however, at present, when grafting grape seedlings, the cut surfaces of the branches to be grafted are spliced together, and then the interface is clamped with a clip. Since the strength of the clip is not easy to control, it is easy for the grafting part to break, and different sizes of clips are required for grape branches of different thicknesses, which is rather troublesome. Summary of the Invention

[0003] The purpose of the present invention is to provide a reasonably designed and easy-to-use adjustable grape rootstock grafting clamp for the defects and deficiencies of the prior art. It can perform corresponding clamping according to the size of the branch, and when clamping, it can also support the branch to avoid breakage at the grafting part, and improve the grafting efficiency and success rate.

[0004] To achieve the above object, the present invention adopts the following technical solutions: It includes a fixed cone, a mounting plate and a fixed block. A fixed block is arranged on the upper side of the fixed cone, and a mounting plate is arranged on the upper side of the fixed block. One side inside the mounting plate is embedded and fixed with a storage battery; It also includes: Reinforcing plates. There are two reinforcing plates, and they are symmetrically and movably inserted into the lower end of the fixed cone on the left and right. A pushing mechanism is arranged inside the fixed cone. The upper end of the pushing mechanism is in cooperation and contact with the fixed block, and the lower end of the pushing mechanism is arranged in cooperation with the reinforcing plate; A threaded tube. The threaded tube is fixed on the bottom wall of the fixed block, and the threaded tube is screwed into the upper end of the fixed cone through threads. A limiting mechanism is arranged inside the upper end of the fixed cone, and the limiting mechanism is arranged in cooperation with the fixed block; A connecting plate. The connecting plate is arranged on the upper side of the fixed block, and the connecting plate is connected to the mounting plate through a lifting mechanism; A mounting rod. The mounting rod is arranged inside the mounting plate. A rotating motor is arranged inside the mounting rod. The rotating motor is connected to the storage battery. After the output shaft of the rotating motor passes through the mounting rod, a rotating plate is fixed, and a clamping mechanism is arranged on the rotating plate; Through the above technical solution, the fixed cone is inserted into the soil on one side of the grape rootstock. The driving mechanism drives the reinforcement plate to move outward, so that the reinforcement plate is inserted into both sides inside the soil, increasing the stability of the fixed cone installed inside the soil. Then, the fixed block is installed on the fixed cone through the threaded pipe, and the limiting mechanism is used for limiting to prevent the threaded pipe from rotating. Then, according to the required height, the lifting mechanism drives the mounting plate to move to a suitable height, so that the clamping mechanism is located at the position where grafting is required. Then, according to the angle of the rootstock at the grafting position, the rotation motor is started. The rotation motor drives the rotating plate to rotate, and the rotating plate drives the clamping mechanism to rotate. Finally, the clamping mechanism can clamp the grafting position of the rootstock.

[0005] As a further improvement of the present invention, the driving mechanism includes: A push rod, which is arranged inside the fixed cone. The upper end of the push rod is in contact with the fixed block in a matching manner. The lower end of the push rod is fixed with a push inclined cone. The inclined sides on the left and right side walls of the push inclined cone are in contact with the two sides of the reinforcement plate in a matching manner; Sliding blocks, there are four sliding blocks, and they are symmetrically fixed in pairs on one side of the two side walls of the reinforcement plate. The sliding blocks are slidably arranged in the sliding grooves on the front and rear inner walls of the fixed cone. Several tension springs are equidistantly fixed on one side wall of the sliding blocks, and the other ends of the tension springs are fixed on the inner walls of the sliding grooves of the fixed cone; A push spring, which is sleeved on the middle end of the push rod. One end of the push spring is fixedly arranged on the inner bottom wall of the cylindrical groove inside the fixed cone. The other end of the push spring is fixed with a limiting ring. The limiting ring is movably arranged in the cylindrical groove inside the fixed cone, and the limiting ring is sleeved and fixed on the push rod; Through the above technical solution, when the fixed block is installed on the fixed cone, the push rod is pushed. The push rod compresses the push spring through the limiting ring. At the same time, the push rod drives the push inclined cone to move downward. The inclined surface of the push inclined cone pushes the two sides of the reinforcement plate, so that the reinforcement plate is inserted into the soil. At this time, the reinforcement plate stretches the tension springs through the sliding blocks on both sides. When the fixed cone needs to be taken out, the fixed block is removed. The elastic force of the push spring drives the limiting ring to move upward. The limiting ring drives the push rod to move upward. The push rod drives the push inclined cone to move upward, so that the push inclined cone is separated from the reinforcement plate. At this time, the reinforcement plate moves into the fixed cone under the pulling force of the tension spring, which is convenient for taking out.

[0006] As a further improvement of the present invention, a pressing frame is sleeved and fixed on the middle end of the fixed cone. The pressing frame is in contact with the soil in a matching manner; it can facilitate driving the fixed cone to move downward.

[0007] As a further improvement of the present invention, the limiting mechanism includes: An active frame, the active frame is movably arranged inside the upper end of a fixed cone, the active frame is arranged outside a threaded pipe, and limit springs are fixed at the four corners of the lower side wall of the active frame, and the lower ends of the limit springs are fixed on the inner wall of the fixed cone; Limit rods, there are four limit rods, and they are respectively fixed at the four corners of the upper side wall of the active frame, and the limit rods are movably inserted into the limit grooves at the four corners of the lower side wall of the fixed block; A toggle plate, the toggle plate is fixed on the outer wall of one side of the active frame, and after the toggle plate passes through the sliding groove on the side wall of the fixed cone, it is suspended outside the fixed cone; Through the above technical solution, when the fixed block is screwed onto the fixed cone, the active frame is pushed downward through the toggle plate, the active frame drives the limit rods to move downward, so that the limit springs are compressed. After the fixed block is screwed onto the fixed cone, the toggle plate is released, and the active frame moves upward under the elastic force of the limit springs and is inserted into the fixed block, so as to limit the fixed block and prevent the fixed block from rotating.

[0008] As a further improvement of the present invention, a baffle is fixed on the lower side wall of the toggle plate, and the baffle is movably inserted into the side wall of the fixed cone; Through the above technical solution, it is convenient to block the sliding groove on the side wall of the fixed cone.

[0009] As a further improvement of the present invention, the lifting mechanism includes: Telescopic connecting rods, there are four telescopic connecting rods, and they are arranged on the four side edges above the connecting plate. The two rod ends at the lower side of the telescopic connecting rods are rotatably connected with lifting blocks through hinge seats, and the lifting blocks are slidably arranged in the sliding grooves on the upper surface of the connecting plate; Rotating rods, there are eight rotating rods, and they are rotatably connected in pairs to the two rod ends on the upper side of the telescopic connecting rods through shaft rods, and the other ends of the rotating rods are connected to the mounting plate through hinge plates; First bidirectional lead screws, there are four first bidirectional lead screws, and they are embedded and rotatably connected in the four side edges of the connecting plate through bearings. The two ends of the first bidirectional lead screws are threadedly connected to the two lifting blocks at the lower end of the same telescopic connecting rod; Linkage bevel gear pairs, there are three linkage bevel gear pairs, and they are respectively embedded in the triangles of the connecting plate. Two bevel gears in the linkage bevel gear pairs are respectively sleeved and fixed on the ends of the adjacent first bidirectional lead screws; A lifting motor, the lifting motor is embedded and fixed in another corner of the connecting plate, the lifting motor is connected to one end of the adjacent first bidirectional lead screw, and the lifting motor is connected to the storage battery; Through the above technical solution, the lifting motor is started, and the lifting motor drives the first bidirectional lead screw connected thereto to rotate. The first bidirectional lead screw, with the cooperation of the linkage bevel gear pair, causes the other three first bidirectional lead screws to rotate synchronously. The first bidirectional lead screw drives the lifting block to move through the threads at both ends. The lifting block drives the rod at the lower end of the telescopic connecting rod to move, and the rod at the top end of the telescopic connecting rod drives the rotating rod to rotate. During the rotation of the rotating rod, the mounting rod is driven to move up and down.

[0010] As a further improvement of the present invention, the clamping mechanism includes: A second bidirectional lead screw, which is embedded and rotatably connected in the rotating plate through a bearing. The middle end of the second bidirectional lead screw is connected to a clamping motor through a bevel gear pair. The clamping motor is embedded and fixed in the rotating plate, and the clamping motor is connected to the storage battery; Moving plates, there are two moving plates, and they are symmetrically arranged on one side of the rotating plate front and back. The protrusions on one side of the moving plate are inserted into the sliding grooves on the side wall of the rotating plate, and the protrusions are threadedly connected to the second bidirectional lead screw; Insertion plates, there are two insertion plates, and they are respectively movably inserted into the moving plates. The inner wall of the insertion plate is connected to the inner wall of the moving plate through a connecting spring. After the outer wall of the insertion plate passes through the side wall of the moving plate, a connecting seat is fixed; Arc-shaped clamping plates, there are three arc-shaped clamping plates. One of them is fixed at the center of the side wall of the rotating plate away from the mounting plate, and the other two arc-shaped clamping plates are symmetrically arranged on one side of the rotating plate front and back. The protrusions on the outer arc surfaces of the two arc-shaped clamping plates are rotatably connected in the connecting seat through a shaft rod; Through the above technical solution, during clamping, the clamping motor is started. The clamping motor drives the second bidirectional lead screw to rotate through the bevel gear pair. The second bidirectional lead screw drives the moving plate to move. The moving plate drives the arc-shaped clamping plate to move through the insertion plate. After the two symmetrically arranged arc-shaped clamping plates front and back abut against the rootstock, the arc-shaped clamping plate can continue to move. The arc-shaped clamping plate rotates on the connecting seat through the protrusions on its outer arc surface. During the rotation, the connecting seat can drive the insertion plate to move outward, and the insertion plate stretches the connecting spring until the three arc-shaped clamping plates wrap around the outer wall of the rootstock at equal angles, thereby improving the clamping effect.

[0011] As a further improvement of the present invention, the mounting rod is movably arranged in the mounting plate. A plurality of limiting grooves are equidistantly arranged on the left and right sides of the outer ring wall of the mounting rod. Limiting strips are arranged on the front and rear sides of the mounting rod and are matched with the limiting grooves. A plurality of abutting springs are fixed on the side walls of the two limiting strips away from the mounting rod, and the other ends of the abutting springs are fixed on the inner wall of the mounting plate. A pushing strip is fixedly arranged on the upper side of the side wall of one of the limiting strips. The pushing strip is located above the mounting rod, and after one side of the pushing strip movably passes through the side wall of the mounting plate, it is located outside the mounting plate. A pushing frame is fixed on the lower side of the side wall of the other limiting strip. The pushing frame is arranged in a "Z" shape. The horizontal bar on the lower side of the pushing frame is located below the mounting rod, and the horizontal bar on the upper side of the pushing frame passes through the other side wall of the mounting plate and is located outside the mounting plate; Through the above technical solution, according to the position of the grafting rootstock, press the ends of the pushing strip and the pushing frame located outside the mounting plate with one hand at the same time, so that the limiting strip moves to the side away from the mounting rod until the limiting strip is separated from the limiting groove. At this time, the abutting spring is compressed, and then the rotating plate can be driven to move outward until the clamping mechanism reaches the appropriate position. Then release the pushing frame and the pushing strip, and under the elastic force of the abutting spring, the limiting strip is reset and inserted into the limiting groove, so as to limit the mounting rod.

[0012] As a further improvement of the present invention, a rotating rod is fixed on the lower surface of the connecting plate, and the rotating rod is rotatably connected in the fixed block through a bearing; Through the above technical solution, after the fixed cone is inserted into the soil, the position of the clamping mechanism can be adjusted.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The reinforcement plate is automatically unfolded after being inserted into the soil, significantly improving the stability of the device in soft soil; at the same time, double locking can be carried out to prevent loosening or deviation during the operation process and ensure the accuracy of the grafting operation; 2. The lifting mechanism is driven by a motor to drive a bidirectional lead screw and a linkage bevel gear pair to realize four-way synchronous lifting and accurately control the grafting height; 3. The clamping mechanism can automatically adapt to rootstocks with different diameters, and uniformly apply force through elastic deformation during the clamping process, which not only ensures firm fixation but also avoids damaging plant tissues, significantly improving the grafting survival rate; 4. The design of the quick adjustment mechanism of the limiting strip that can be operated by hand and the auxiliary positioning of the rotating rod reduce the operation complexity.

[0030] When using the present invention, the fixed cone 1 is inserted into the soil on one side of the grape rootstock. When the fixed block 3 is installed on the fixed cone 1, the movable frame 8-1 is pushed downward by the toggle plate 8-4, and the movable frame 8-1 drives the limit rod 8-3 to move downward, so that the limit spring 8-2 is compressed. The fixed block 3 is installed on the fixed cone 1 through the threaded tube 7 and the push rod 6-1 is pushed. The push rod 6-1 compresses the push spring 6-5 through the limit ring 6-6, and at the same time, the push rod 6-1 drives the push cone 6-2 downward. Move, push the inclined surface of the inclined cone 6-2 to push the reinforcement plates 5 on both sides, so that the reinforcement plates 5 are inserted into the soil, which increases the stability of the fixed cone 1 installed inside the soil. At this time, the reinforcement plate 5 stretches the tension spring 6-4 through the sliding blocks 6-3 on both sides. After the fixed block 3 is rotated onto the fixed cone 1, the toggle plate 8-4 is released, and the movable frame 8-1 moves upward under the elastic force of the limit spring 8-2 and is inserted into the fixed block 3, so that the fixed block 3 can be limited to prevent the fixed block 3 from rotating. Then, according to the required height, the lifting motor 10-6 is started, and the lifting motor 10-6 drives the connected No. 1 bidirectional screw rod 10-4 to rotate, and the No. 1 bidirectional screw rod 10-4 makes the other three No. 1 bidirectional screw rods 10-4 rotate synchronously with the cooperation of the linkage bevel gear pair 10-5, and the No. 1 bidirectional screw rod 10-4 drives the lifting block 10-2 to move through the threads at both ends, and the lifting block 10-2 drives the end rod at the lower end of the telescopic connecting rod 10-1 to move, and the end rod at the top of the telescopic connecting rod 10-1 drives the rotating rod 10-3 to rotate, and the rotating rod 10-3 drives the installation rod 11 to move up and down during the rotation process, so that the clamping mechanism 14 is located at the required grafting position, and then according to the angle of the rootstock at the grafting position, the rotating motor 12 is started, and the rotating motor 12 drives the rotating plate 13 to rotate, and the rotating plate 13 drives the clamping mechanism 14 to rotate; During clamping, according to the position of the grafting rootstock, one hand simultaneously presses the pushing bar 19 and one end of the pushing frame 20 located outside the mounting plate 2, so that the limiting bar 17 moves to the side away from the mounting rod 11 until the limiting bar 17 separates from the limiting groove 11-1. At this time, the abutting spring 18 is compressed, and then the rotating plate 13 can be driven to move outward until the clamping mechanism 14 reaches the appropriate position. Then release the pushing frame 20 and the pushing bar 19. Under the elastic force of the lower side of the abutting spring 18, the limiting bar 17 is reset and inserted into the limiting groove 11-1, so as to limit the mounting rod 11. Start the clamping motor 14-2, and the clamping motor 14-2 drives the second bidirectional lead screw 14-1 to rotate through the bevel gear pair. The second bidirectional lead screw 14-1 drives the moving plate 14-3 to move, and the moving plate 14-3 drives the arc-shaped clamping plate 14-6 to move through the inserting plate 14-4. After the two arc-shaped clamping plates 14-6 symmetrically arranged before and after abut against the rootstock, the arc-shaped clamping plate 14-6 can continue to move. The arc-shaped clamping plate 14-6 rotates on the connecting seat 14-5 through the protrusions on its outer arc surface. During the rotation process, the connecting seat 14-5 can drive the inserting plate 14-4 to move outward, and the inserting plate 14-4 stretches the connecting spring until the three arc-shaped clamping plates 14-6 wrap around the outer ring wall of the rootstock at equal angles, improving the clamping effect; When the fixing cone 1 needs to be taken out, loosen the limiting mechanism 8, unscrew the fixing block 3 and the threaded pipe 7. The elastic force of the pushing spring 6-5 drives the limiting ring 6-6 to move upward. The limiting ring 6-6 drives the pushing rod 6-1 to move upward, and the pushing rod 6-1 drives the pushing inclined cone 6-2 to move upward, so that the pushing inclined cone 6-2 separates from the reinforcing plate 5. At this time, the reinforcing plate 5 moves into the fixing cone 1 under the pulling force of the tension spring 6-4, which is convenient for taking off.

[0031] Compared with the prior art, the beneficial effects of the present specific embodiment are as follows: 1. Through the linkage design of the fixing cone 1, the reinforcing plate 5 and the pushing mechanism 6, the reinforcing plate 5 is automatically unfolded after being inserted into the soil, significantly improving the stability of the device in soft soil; at the same time, the threaded pipe 7 and the limiting mechanism 8 are used for double locking to prevent loosening or deviation during the operation process and ensure the accuracy of the grafting operation; 2. The lifting mechanism 10 drives the first bidirectional lead screw 10-4 and the linkage bevel gear pair 10-5 through the lifting motor 10-6 to realize four-way synchronous lifting and accurately control the grafting height; the rotating motor 12 cooperates with the telescopic mounting rod 11 to support 360° angle adjustment, meeting the grafting requirements of rootstocks with different growth angles and greatly improving the adaptability; 3. The three arc-shaped clamping plates 14-6 cooperate with the second bidirectional lead screw 14-1 and the connecting spring buffer system, which can automatically adapt to rootstocks with different diameters and apply force evenly through elastic deformation during the clamping process, ensuring firm fixation and avoiding damage to plant tissues, and significantly improving the grafting survival rate; 4. Designs such as the quick adjustment mechanism of the manually operable limit strip 17 and the auxiliary positioning of the rotating rod 21 reduce the operation complexity; the modular structure such as the detachable fixing block 3 is convenient for maintenance and transportation, which is especially suitable for the efficient operation requirements of outdoor orchards.

[0032] For those skilled in the art, they can modify the technical solutions recorded in the foregoing embodiments and perform equivalent replacements of some technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
