Description

Technical Field

[0001] The present invention relates to the technical field of grafting, and specifically to a forest tree grafting binding device. Background Art

[0002] During the grafting process, binding is a crucial link to ensure survival: First, the binding needs to firmly fix the joint between the scion and the rootstock, prevent displacement or loosening, and ensure that the cambiums of both sides are in full contact to promote the growth of callus; Second, the binding material needs to have both breathability and waterproofness, which can not only reduce water loss and avoid drying of the cut, but also block the invasion of germs. Attention should be paid to the appropriate tightness during operation. If it is too tight, it will compress the tissue and hinder nutrient transport. If it is too loose, it cannot be effectively fixed. The traditional manual binding method usually uses a narrow grafting film for multi-loop spiral winding, and realizes the sealing of the joint between the rootstock and the scion through progressive wrapping. Compared with the single-layer covering method of the wide grafting film, it can effectively avoid the wrinkles and incomplete wrapping of the grafting film. However, during manual operation, it will be limited by the working space, and the effective exertion of the manual winding force cannot be guaranteed; In addition, the winding density is affected by the operator's experience, and there are individual differences in the stability of the microenvironment at the joint, which affects the grafting success rate. There is also an automatic grafting device for greenhouse nursery jujube trees with the application number CN202110935801.7. This patent document discloses a solution that uses an electric component to drive the film wrapping mechanism to operate. Specifically: the conveyor belt starts, drives the grafted jujube saplings to move forward, conveys the jujube saplings to directly below the film wrapping mechanism, and pre-winds the film on the reel. When grafting the grafted jujube saplings is required, the film is pulled out, one end of it is attached to the rootstock, then the reduction motor starts, drives the driving rod, the electric telescopic rod and the reel to rotate, continuously winds the film on the rootstock, then the electric telescopic rod slowly contracts, and the winding position of the film continuously moves up until the entire grafting position is completely wrapped, and then the film is cut off to complete the grafting. However, when using the technical solution in the above patent document, when using the film wrapping mechanism to perform the initial film winding operation outside the rootstock and the scion, one end of the film needs to be manually pulled out, and manual participation still cannot be completely replaced; due to the fixed winding angle of the winding mechanism, it is impossible to achieve the figure-eight winding trajectory imitating manual work, and there is a risk of wrinkles and incomplete wrapping caused by uneven film tension; In addition, the equipment is large in size and inconvenient to carry, and it is difficult to meet the flexible operation requirements of outdoor grafting scenarios. Therefore, the present application provides a forest tree grafting binding device. Summary of the Invention

[0003] In order to solve the deficiencies in the above-mentioned prior art, the purpose of the present invention is to provide a forest tree grafting binding device, which can overcome the defects that the wide-width grafting film is prone to produce wrinkles and is not tightly wrapped, quickly seal the joint part of the rootstock and scion, is not limited by the experience of operators, has good operation convenience, and a high grafting success rate.

[0004] The technical solution adopted by the present invention to solve its technical problems is as follows: A forest tree grafting binding device is provided, which includes a flexible binding pad and two docking seats. The two docking seats are respectively connected to both ends of the flexible binding pad. The two docking seats are inserted and connected to each other and coupled by magnetic adsorption. The flexible binding pad surrounds the outside of the rootstock. A grafting film is provided at the position of the flexible binding pad on the side of the rootstock and scion. A light-shielding cover made of flexible material is covered on the outside of the grafting film. The inner side of the light-shielding cover and the outer side of the grafting film form a sand storage cavity. Light-transmitting holes are provided on the light-shielding cover, and the positions of the light-transmitting holes correspond to the positions of the scions.

[0005] Further, film winding shafts are respectively fixedly installed at both ends of the flexible binding pad. The film winding shafts are rotatably installed on the docking seats. The end shafts of the film winding shafts penetrate through the docking seats and are inserted and connected to the torsion adjustment sleeves 9 on the docking seats and locked in position by fasteners.

[0006] In the present application, for the installation method of the light-shielding cover, an optional technical solution is: the edge of the light-shielding cover is adhesively and fixedly connected to the flexible binding pad.

[0007] In the present application, for the installation method of the light-shielding cover, an optional technical solution is: a plurality of straps are respectively fixedly installed on both sides of the light-shielding cover, and the other ends of the straps are connected to the docking seats.

[0008] Among them, for the method of adjusting the tightness of the straps, an optional technical solution is: open-ended sleeves are respectively fixedly installed at the upper and lower ends of the side of the docking seat. Two pistons on the stretching column are respectively inserted and slidably connected to the two open-ended sleeves. The pistons and the open-ended sleeves are locked in position by fasteners. The outer side of the stretching column is in abutting contact with the inner side of the end of the strap.

[0009] Among them, for the method of adjusting the tightness of the straps, another optional technical solution is: open-ended sleeves and closed sleeves are respectively fixedly installed at the upper and lower ends of the side of the docking seat. Two pistons on the stretching column are respectively inserted and slidably connected to the open-ended sleeve and the closed sleeve. A tension spring is fixedly installed between the piston and the open-ended sleeve; a conduit is fixedly and communicatively arranged at the end of the closed sleeve, and the other end of the conduit is connected to a water supply pump and a water tank through a hose.

[0010] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. For the tree grafting binding device of the present invention example, adjust the position of the flexible binding pad so that the middle part of the inner side of the flexible binding pad corresponds to the grafting position of the rootstock and the scion. Buckle the grafting film outside the grafting area, then bypass the rootstock and on the other side of the rootstock, magnetically dock the two docking seats together; since the flexible binding pad is only provided with a single layer and does not require multiple winding, the requirement for the operating space outside the rootstock is reduced, and the sealing operation of the combined part of the rootstock and the scion can be quickly implemented, which is not limited by the experience of the operator and has good operation convenience.

[0011] 2. For the tree grafting binding device of the present invention example, install a light-shielding cover outside the grafting film. Through the light-transmitting hole, inject sand materials with poor water absorption capacity such as quartz sand into the sand storage cavity, so that the fitting degree between the grafting film and the side parts of the rootstock and the scion is increased, and the problems of easy wrinkling and incomplete wrapping of the wide-width grafting film are overcome; since the light-transmitting hole is arranged at the upper end of the side part of the light-shielding cover, the sand material corresponds to the grafting area of the rootstock and the scion, and the bud on the scion is close to the position above the area and can receive the light transmitted through the light-transmitting hole, ensuring the normal growth of the bud and high grafting success rate; a light-transmitting plug is installed at the light-transmitting hole to prevent rainwater and dust from invading.

[0012] 3. For the tree grafting binding device of the present invention example, loosen the fastener and rotate the film winding shaft and then tighten the fastener to wind or loosen a section of the end of the flexible binding pad, so that the flexible binding pad matches trees with different diameters, and the device has good versatility.

[0013] 4. For the tree grafting binding device of the present invention example, manually adjust the position of the piston in the open sleeve and use a fastener for limitation to change the position of the stretching column, adjust the tightness of the binding belt, apply a pulling force to both sides of the light-shielding cover, so that the sand storage cavity between the inner side surface of the light-shielding cover and the outer side surface of the grafting film undergoes a tightening deformation, and the quartz sand is filled in a dense state in the sand storage cavity, making the grafting film fit more tightly with the rootstock and the scion and maintaining it, and increasing the anti-interference performance during the use of the device.

[0014] 5. For the tree grafting binding device of the present invention example, start the water supply pump and inject water into the conduit. Under the action of water pressure, the piston located at the lower side moves towards the direction close to the flexible binding pad, so that the light-shielding cover bulges again under the action of its own elastic performance, increasing the size of the sand storage cavity between the inner side surface of the light-shielding cover and the outer side surface of the grafting film, making the quartz sand in the sand storage cavity filled in a loose state, reducing the tightness of the contact position between the grafting film and the rootstock and the scion, and providing a growth space for the bud on the scion; in combination with the use of the conduit and the drip irrigation head, apply the water in the water tank to the side of the tree and slowly seep and diffuse along the tree trunk towards the base to provide the growth requirements for the growth of the tree and the bud on the scion.

[0023] Embodiment 1: As Figure 1 , Figure 2 and Figure 3 shown, this embodiment provides a forest tree grafting binding device, including a flexible binding pad 11 and two docking seats 15. The two docking seats 15 are respectively connected to both ends of the flexible binding pad 11. The two docking seats 15 are inserted and connected to each other and coupled by magnetic adsorption. The flexible binding pad 11 surrounds the outside of the rootstock 1. The flexible binding pad 11 is provided with a grafting film 12 at the position on the side of the rootstock 1 and the scion 2. The grafting film 12 uses a commercially available PE microporous film product. The outside of the grafting film 12 is covered with a light-shielding cover 21 made of a flexible material. The inner side surface of the light-shielding cover 21 and the outer side surface of the grafting film 12 form a sand storage cavity. The light-shielding cover 21 is provided with light-transmitting holes 22, and the positions of the light-transmitting holes 22 correspond to the positions of the scions 2.

[0024] The light-shielding cover 21 is used to shield the area other than the buds on the scion 2, so as to avoid the scion 2 from rotting due to the accumulation of more water inside the grafting film 12 caused by transpiration due to sunlight irradiation.

[0025] Among them, the way that the two docking seats 15 are magnetically adsorbed and connected to each other is as follows: a magnetic strip 18 is fixedly installed on the docking seat 15, and the magnetic strips 18 on the two docking seats 15 are coupled and connected by magnetic adsorption; or a power-off electromagnetic holding electromagnet is fixedly installed on one side of the docking seat 15, and an iron sheet is fixedly installed on the other side of the docking seat 15, and the power-off electromagnetic holding electromagnet and the iron sheet are coupled and connected by magnetic adsorption.

[0026] The specific details of using the forest tree grafting binding device of the present application are as follows: I. Preparation before use; According to the diameter size of the grafting position of the rootstock 1, a flexible binding pad 11 with a specified length is selected, and according to the plant type and growth air permeability requirements of the scion 2, a grafting film 12 with a specified thickness is selected.

[0027] II. Cover the outside of the rootstock 1 and the scion 2 with a film; First, cut a split on the rootstock 1, cut the lower end of the scion 2 into a wedge shape, keep the bud of the scion 2 facing upward, insert the scion 2 into the split on the rootstock 1, and ensure that the two are inserted tightly and fit together; After that, adjust the position of the flexible binding pad 11 so that the middle part of the inner side of the flexible binding pad 11 corresponds to the grafting position of the rootstock 1 and the scion 2. Buckle the grafting film 12 outside the grafting area, then bypass the rootstock 1 and on the other side of the rootstock 1, magnetically dock the two docking seats 15 together.

[0028] III. Closely fit the grafting film 12 with the grafting positions of the rootstock 1 and the scion 2; Install a light-shielding cover 21 on the outside of the grafting film 12. Through the light-transmitting hole 22, inject sand materials with poor water absorption capacity such as quartz sand into the sand storage cavity, so that the degree of fit between the grafting film 12 and the side parts of the rootstock 1 and the scion 2 is increased, overcoming the problems that the wide-width grafting film is prone to produce wrinkles and is not tightly wrapped.

[0029] In the above step II, since the flexible binding pad 11 is only provided with a single layer and does not need to be wound in multiple layers, the requirement for the operating space outside the rootstock 1 is reduced, and the joint part of the rootstock and the scion can be quickly sealed, without being limited by the experience of the operator, and the operation convenience is good.

[0030] In the above step III, since the light-transmitting hole 22 is provided at the upper end of the side part of the light-shielding cover 21, the sand material corresponds to the grafting area of the rootstock 1 and the scion 2, and the bud on the scion 2 is close to the upper position of the area, and can receive the light transmitted through the light-transmitting hole 22, ensuring the normal growth of the bud and having a high grafting success rate; a light-transmitting plug is installed at the light-transmitting hole 22 to prevent rainwater and sand and dust from entering.

[0031] In this embodiment, the edge of the sunshade 21 is bonded and fixed to the flexible binding pad 11, and the toughness of the flexible binding pad 11 is stronger than the ability of the grafting membrane 12 to resist deformation, so that the quartz sand in the sand storage chamber will not exert excessive pulling force on the grafting membrane 12, thereby ensuring the stable use of the equipment.

[0032] In this embodiment, the end of the flexible binding pad 11 is bonded and fixedly connected to the docking seat 15. When facing stock 1 with different diameters, the flexible binding pad 1 and the two docking seats 15 are replaced and used together.

[0033] Embodiment 2: The features of this embodiment that are the same as those of the first embodiment are not described in detail. The difference between this embodiment and the first embodiment is that: Figure 3 and Figure 4 As shown, in this embodiment, the two ends of the flexible binding pad 11 are respectively fixedly installed with a coating winding shaft 14, and the coating winding shaft 14 is rotatably installed on the docking seat 15. The rotating shaft at the end of the coating winding shaft 14 passes through the docking seat 15 and is plugged and connected to the torsion adjustment sleeve 19 on the docking seat 15 and is locked in position by a fastener; loosen the fastener and rotate the coating winding shaft 14 and then tighten the fastener to wrap or loosen the end of the flexible binding pad 11 for a certain length, so that the flexible binding pad 11 matches trees of different diameters, and the equipment has good versatility.

[0034] like Figure 4 and Figure 5 As shown, flexible pads 151 are fixedly installed at the upper and lower ends of the docking seat 15, respectively. The flexible pads 151 are in contact with the outer side of the rootstock 1. The flexible pads 151 are located in the upper area where the end of the flexible binding pad 11 is connected to the docking seat 15, so as to isolate dust and prevent dust from entering between the outer side of the rootstock 1 and the inner side of the flexible binding pad 11.

[0035] Embodiment three: The features of this embodiment that are the same as those of the first embodiment are not described in detail. The difference between this embodiment and the first embodiment is that: Figure 2 , Figure 3 and Figure 4 As shown, in this embodiment, a plurality of reinforcement strips 13 are respectively embedded at the upper and lower ends of the flexible binding pad 11. The reinforcement strips 13 are made of aluminum and copper. The reinforcement strips 13 are U-shaped as a whole. The plurality of reinforcement strips 13 on one side are staggered with each other. After the flexible binding pad 11 is surrounded on the outside of the stock 1, the reinforcement strips 13 are manually pressed so that the shape of the reinforcement strips 13 matches the shape of the outside of the stock 1, thereby increasing the sealing performance at the contact between the stock 1 and the flexible binding pad 11.

[0036] Embodiment 4: The features of this embodiment that are the same as those of Embodiment 1 will not be elaborated again. The differences between this embodiment and Embodiment 1 are as follows: In this embodiment, a plurality of straps 23 are fixedly installed on both sides of the light-shielding cover 21 respectively. The other ends of the straps 23 are connected to the docking seat 15. The straps 23 are made of elastic materials such as rubber, and use their own elastic deformation characteristics to maintain a taut state.

[0037] In this embodiment, open-ended sleeves 33 are fixedly installed at the upper and lower ends of the side of the docking seat 15 respectively. Two pistons 32 on the stretching column 31 are respectively inserted and slidably connected to the two open-ended sleeves 33. The positions of the pistons 32 and the open-ended sleeves 33 are locked by fasteners. The outer side of the stretching column 31 is in abutting contact with the inner side of the end of the strap 23.

[0038] Among them, a plurality of threaded holes are provided on the side of the open-ended sleeve 33. A fastener such as a stud is screwed into a specified threaded hole to limit the axial displacement of the piston 32. Since the outer side of the stretching column 31 is in abutting contact with the inner side of the end of the strap 23, the strap 23 made of elastic materials such as rubber always exerts a tightening force on the stretching column 31 and the piston 32.

[0039] Manually adjust the position of the piston 32 in the open-ended sleeve 33 and use a fastener to limit the position, change the position of the stretching column 31, adjust the tightness of the strap 23, apply a pulling force to both sides of the light-shielding cover 21, so that the storage cavity between the inner side of the light-shielding cover 21 and the outer side of the grafting film 12 undergoes a tightening deformation, and the quartz sand is filled in a dense state in the storage cavity, making the grafting film 12 fit more closely with the rootstock 1 and the scion 2 and maintaining it, increasing the anti-interference performance during the use of the equipment.

[0040] Embodiment Five: The features of this embodiment that are the same as those of Embodiment 1 will not be elaborated again. The differences between this embodiment and Embodiment 1 are as follows: As Figure 5 and Figure 6 shown, in this embodiment, open-ended sleeves 33 and closed sleeves 34 are fixedly installed at the upper and lower ends of the side of the docking seat 15 respectively. Two pistons 32 on the stretching column 31 are respectively inserted and slidably connected to the open-ended sleeve 33 and the closed sleeve 34. A tension spring 331 is fixedly installed between the piston 32 and the open-ended sleeve 33. The end of the closed sleeve 34 is fixedly connected and communicated with a conduit 35. The other end of the conduit 35 is connected to a water supply pump and a water tank through a hose. A positioning bracket 36 is detachably and fixedly installed on the docking seat 15. The end of the positioning bracket 36 is sleeved and connected to the outer side of the middle part of the conduit 35 to reinforce and support the conduit 35.

[0041] Under the action of the tension spring 331, the piston 32 located above the stretching column 31 always has a tendency to move away from the flexible binding pad 11, making the strap 23 taut, applying a pulling force to both sides of the light-shielding cover 21, and maintaining the tightened state of the light-shielding cover 21; When it is necessary to loosen the binding strap 23, start the water supply pump to inject water into the conduit 35. Under the action of water pressure, the piston 32 located on the lower side moves towards the direction close to the flexible binding pad 11, so that the light-shielding cover 21 bulges again under the action of its own elastic performance, increasing the size of the sand storage cavity between the inner side surface of the light-shielding cover 21 and the outer side surface of the grafting film 12, enabling the quartz sand in the sand storage cavity to be filled in a loose state, reducing the tightness of the contact position between the grafting film 12 and the rootstock 1 and the scion 2, and providing a growth space for the buds on the scion 2.

[0042] To improve the water replenishment efficiency of the device during the bud germination period of the scion 2, as Figure 6 shown, a plurality of drip irrigation heads 351 are arranged on the side of the conduit 35. By combining the use of the conduit 35 and the drip irrigation heads 351, the water in the water tank is applied to the side of the forest tree, slowly infiltrating and diffusing along the branches of the forest tree towards the base, providing the growth requirements for the growth of the forest tree and the buds on the scion 2.

[0043] The above description is only the preferred embodiment of the present application and the explanation of the applied technical principles. Those skilled in the art should understand that the scope of the invention involved in the present application is not limited to the technical solution formed by the specific combination of the above technical features, and should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the inventive concept.
