Description

Technical Field

[0001] The invention relates to the field of seedling cultivation, in particular to a rubber seedling bud grafting segmented rotary bud cutting machine and a bud cutting control method. Background Art

[0002] Rubber trees are the world's primary source of natural rubber, and their cultivation and development are crucial to the development of the rubber industry. To ensure the breeding of high-quality rubber tree varieties, increase rubber yields, and enhance disease resistance, budding is widely used. Budding is an asexual propagation method that involves grafting buds from high-quality mother trees onto rootstocks, allowing them to grow into plants with superior traits. This technique preserves the tree's superior genetic characteristics, shortens the growth cycle, and increases the survival rate of seedlings, making it a key component of modern rubber cultivation.

[0003] At present, the budding process of rubber seedlings mainly relies on manual operation. The cutting of buds is usually done manually using a budding knife or other hand-held tools. Common methods include T-shaped budding, sheet budding and chip budding. Although these traditional methods have been used for a long time, they still have many limitations. The quality of manually cut buds is greatly affected by the operator's technical level. The depth, angle and size of the cutting are difficult to maintain consistency, which can easily cause damage to the buds or irregular shapes, thereby affecting the success rate of grafting. In addition, manual operation is inefficient and labor-intensive, making it difficult to meet the needs of large-scale seedling cultivation. Especially in modern agricultural production, manual budding methods can no longer meet the requirements of the rubber planting industry for efficient and precise grafting.

[0004] In the prior art, CN 115777364 A discloses a rotary cutting type rubber seedling bud extracting machine and a bud extracting method, wherein the bud extracting machine part includes a frame, a pressing device, a rotary cutting device, a lower hopper and a control device. The frame is the carrier of the entire bud extracting machine, and the pressing device, the rotary connecting device and the lower hopper are all installed on the frame. The two ends of the bud extracting strip are placed on the support pads of the pressing device, and then the pressing pads are driven by the pressing electric cylinder to press the two ends of the bud strip. The rocker arm electric cylinder in the rotary cutting device is used to drive the rocker arm to swing, so that the cutter installed at the end of the rocker arm can move back and forth along the rectangular groove to cut the bud strip and extract the bud. The cut bud falls from the rectangular groove to the lower hopper and slides out. Although this device can replace manual bud removal, its bud removal efficiency is still very low. The specific analysis is as follows: 1. When the cutter rotates to remove buds, only one bud strip can be cut from the process of knife entry to knife exit, and its cutting efficiency is low; 2. Since the position of the cutter is fixed, and in order to ensure that the cut bud strip has a bud bag, the position of the bud bag needs to be manually adjusted before the tree stem is installed to ensure that the bud bag can be cut off smoothly. Each tree stem may have 4-5 bud bags in multiple different directions and positions, so it is necessary to manually adjust the position of the tree stem multiple times, which is cumbersome to operate and leads to low bud cutting efficiency.

[0005] Therefore, providing a bud cutting machine with high bud cutting efficiency has become a technical problem in this field. Summary of the Invention

[0012] A control operating system is provided, wherein the tree stem clamping and rotating device, the segmented tangential cutting and rotating device, and the seedling bud collecting device are all connected to the control operating system.

[0013] As a preferred technical solution, the height adjustment device includes a pneumatic telescopic cylinder, the cylinder end of the pneumatic telescopic cylinder is fixedly mounted on the operating platform, the telescopic end of the pneumatic telescopic cylinder is vertically fixed with a pneumatic telescopic frame, and the tree stem clamping device and the tree stem rotating device are connected to the pneumatic telescopic frame.

[0014] As an optimal technical solution, the tree trunk clamping device includes a clamping chuck, the external fixed end of the clamping chuck is fixedly connected to the chuck shaft, and the chuck shaft is installed on the pneumatic telescopic frame through a bearing seat; the tree trunk rotation device includes a motor mounting frame fixed on the pneumatic telescopic frame, and a tree trunk drive motor is installed on the motor mounting frame, and the power output end of the tree trunk drive motor is connected to the chuck shaft through a coupling.

[0015] As a preferred technical solution, the tool rotation device includes a tool shaft, the top end of the segmented chord cutter is fixed on the tool shaft, the tool shaft is located above the tree stem to be clamped and parallel to the axis of the tree stem, both ends of the tool shaft are rotatably mounted on the operating platform, and one end of the tool shaft is also connected to the power output end of the tool drive motor.

[0016] As a preferred technical solution, the rotation axis of the tool shaft and the axis of the tree stem to be clamped are in the same vertical plane.

[0017] As an optimal technical solution, the segmented chord cutting knife includes a cutter head mounting plate, the top of the cutter head mounting plate is provided with a mounting sleeve fixedly connected to the tool rotation device, the chord cutting horizontal knife is provided on one side of the bottom end of the cutter head mounting plate, the chord cutting horizontal knife is perpendicular to the cutter head mounting plate, and the chord cutting horizontal knife is extended toward the axial direction of the tree trunk to be clamped, the outer end side of the chord cutting horizontal knife is provided with a chord cutting blade that cuts into the surface of the tree trunk to be clamped, the segmented vertical knife is arranged perpendicular to the chord cutting horizontal knife, and the outer end of the segmented vertical knife is provided with a segmented blade that cuts into the surface of the tree trunk to be clamped.

[0018] As a preferred technical solution, the chord cutting edge and the segmented edge are both V-shaped edges.

[0019] As an optimal technical solution, the seedling bud collection device includes a cut bud collection box located below the segmented chord cutter, and a collection box inclined baffle is provided on one side of the cut bud collection box. The collection box inclined baffle is located on the knife-out side of the segmented chord cutter, and the height of the collection box inclined baffle is higher than the cutting height of the segmented chord cutter.

[0020] Another preferred technical solution is a rubber seedling bud grafting segmented rotary bud cutting control method, which uses the above-mentioned rubber seedling bud grafting segmented rotary bud cutting machine, comprising the following steps:

[0021] S1. Start the control system and check whether the tree stem clamping and rotating device, the segmented tangential cutting and rotating device, and the seedling bud collecting device are functioning properly. If the devices are functioning properly, proceed to the next step; otherwise, perform repairs immediately.

[0022] S2, select the rubber tree stem of appropriate length, clamp and fix it by two tree stem clamping rotating devices;

[0023] S3. Adjust the height of the tree stem by the height adjustment device to ensure the cutting distance between the tree stem and the segmented string cutter;

[0024] S4. The segmented tangential cutting rotating device is started, and the tool rotating device drives the segmented tangential cutting knife to rotate. When the rotation contacts the surface of the tree stem, the tangential cutting horizontal knife cuts the surface of the tree stem tangentially, and the segmented vertical knife cuts the surface of the tree stem radially.

[0026] S6. Turn off the tree stem rotation device and the segmented chord cutting rotation device, release the fixation of the tree stem, and take out the tree stem that has completed bud cutting; and return the height adjustment device to the initial position to prepare for the next bud cutting operation.

[0027] Due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0028] 1. The stem clamping and rotating device in the present invention is used to clamp and fix the stem, and drive the stem to intermittently rotate axially in 90° increments to meet the 360° full-circle cutting requirements of the stem; the segmented tangential cutting rotating device is used to cooperate with the tangential cutting and radial cutting of the stem surface, and cut multiple small segmented seedling bud tree segments in one time; through the integrated design of the stem clamping and rotating device and the segmented tangential cutting rotating device, automated and precise bud cutting of rubber seedling stems is achieved, effectively solving the problems of low efficiency, high labor intensity and uneven cutting of traditional manual bud cutting, and greatly improving the overall operating efficiency.

[0029] 2. The present invention provides a rotary bud cutting method, in which the tool rotation axis is parallel to the axis of the tree trunk, which can realize horizontal tangential cutting. At the same time, combined with the characteristics of the tree trunk intermittent circumferential rotation in 90° increments, it is used to meet the 360° full-circle cutting of the tree trunk; at the same time, combined with the segmented bud cutting method, vertical segmented cutting can be realized, which can not only cut off multiple sections of seedling bud tree segments at one time, but also ensure that the bud body is completely separated from the trunk, avoiding damage to the bud body due to excessive local pressure, and ensuring cutting accuracy and bud integrity.

[0030] 3. The equipment of the present invention performs full-circle cutting in a full-coverage manner. It no longer requires manual adjustment of the cutting position each time as in the prior art. In this equipment, after the tree stem is clamped once, full-circle segmented cutting is adopted, which can meet the requirement of cutting off all bud bags of the tree stem at one time. This full-coverage cutting method will inevitably cut off the seedling bud tree segment with bud bags, and then the required seedling bud tree segment can be selected. This method can greatly improve the bud cutting production efficiency.

[0031] 4. The present invention introduces a height adjustment device to achieve precise adjustment of the height and position of the tree stem, ensuring that the cutter is always in the best cutting state. The flexible adjustment mechanism is suitable for tree stems of various specifications and can accurately set the cutting spacing to ensure that each bud is completely cut. At the same time, during the cutting process, the height of the tree stem can also be adjusted, thereby minimizing the amount of tree cutting while ensuring the cutting needs of the seedling buds.

DETAILED DESCRIPTION

[0042] The present invention will be further described below with reference to the accompanying drawings and examples. In the following detailed description, certain exemplary embodiments of the present invention are described by way of illustration only. It is understood that those skilled in the art will recognize that the described embodiments may be modified in various ways without departing from the spirit and scope of the present invention. Therefore, the drawings and description are illustrative in nature and are not intended to limit the scope of the claims.

[0043] like Figures 1 to 5 As shown, a rubber seedling bud grafting segmented rotary bud cutting machine includes an operating platform 100, a tree stem clamping and rotating device 200, a segmented tangential cutting rotating device 300, a seedling bud collecting device 400 and a control operating system; wherein the operating platform 100 serves as a mounting base for other devices, the tree stem clamping and rotating device 200, the segmented tangential cutting rotating device 300, and the seedling bud collecting device 400 are directly or indirectly mounted on the operating platform 100, and the tree stem clamping and rotating device 200, the segmented tangential cutting rotating device 300, and the seedling bud collecting device 400 are all connected to the control operating system, and the control operating system is used to control each component to operate in an orderly manner.

[0044] The operating platform 100 is placed horizontally and fixed to the ground to prevent the bud cutter from tipping over due to an unstable center of gravity.

[0045] The tree stem clamping and rotating device 200 is used to clamp and secure a tree stem and drive the stem to intermittently rotate axially in 90° increments, enabling a full 360° circumferential cut of the stem. The tree stem clamping and rotating device 200 includes height adjustment devices located on the left and right ends of the operating platform 100. The telescopic ends of the height adjustment devices are upwardly mounted with a tree stem clamping device and a tree stem rotating device that drives the tree stem clamping device to intermittently rotate circumferentially in 90° increments. The two tree stem clamping devices are positioned opposite each other on the left and right sides to horizontally clamp the ends of the tree stem. The height adjustment device is used to adjust the height of the tree stem clamping device and the tree stem rotating device, that is, to adjust the height of the tree stem. When the diameters of the clamped tree stems vary greatly, the position of the tree stem in relation to the cutting tool after being clamped will change accordingly. In order to ensure the requirement of four full-circle cuts intermittently in 90° increments, the height of the tree stem needs to be adjusted so that the cutting position between the tool and the tree stem is accurate. At the same time, when cutting, since the tool cuts in an arc around the center of a circle, the cutting line formed on the surface of the tree stem is an arc, which will cause the amount of tree cut to be too large. Therefore, during the cutting process, the height adjustment device will correspondingly move downward a small amount and then upward a small amount, that is, drive the tree stem to first slightly adjust downward and then slightly adjust upward, to change the cutting position between the tool and the tree stem, thereby minimizing the amount of tree cut while ensuring the cutting requirements of the seedling buds. The tree stem clamping device is used to clamp and fix the tree stem, and the tree stem rotating device is used to drive the tree stem clamping device and the tree stem thereon to rotate intermittently at a certain angle.

[0046] The height adjustment device includes a pneumatic telescopic cylinder 201, the cylinder end of which is fixedly mounted on the operating platform 100. A pneumatic telescopic frame 202 is vertically fixed to the telescopic end of the pneumatic telescopic cylinder 201. The tree stem clamping device and the tree stem rotation device are connected to the pneumatic telescopic frame 202. The pneumatic telescopic cylinder 201 is fixed to the operating platform 100 by fixing ears, bolts, etc. to prevent it from shaking.

[0047] The tree trunk clamping device includes a clamping jaw chuck 203, the outer fixed end of which is fixedly connected to a chuck shaft 204. The chuck shaft 204 is mounted on the pneumatic telescopic frame 202 via a bearing seat. The tree trunk rotation device includes a motor mounting bracket fixed to the pneumatic telescopic frame 202, on which a tree trunk drive motor 205 is mounted. The power output end of the tree trunk drive motor 205 is transmission-connected to the chuck shaft 204 via a coupling. The clamping jaw chuck 203 is a prior art product and will not be described in detail here.

[0048] In addition, when performing the fixing operation of the rubber tree stem, the worker can first place the stem between the two clamping jaws 203, drive the clamping jaws to tighten, and thus achieve a firm clamping of the stems of different thicknesses. When the stem drive motor 205 is started, its output shaft drives the coupling and the clamping jaws 203 to rotate together, so that the stem clamped by the stem clamp undergoes a corresponding rotational movement, which is convenient for subsequent multi-angle or full-circle cutting of the stem. At the same time, the cooperation between the pneumatic telescopic frame 202 and the motor mounting frame, on the one hand, ensures the stable installation and position adjustment of the stem drive motor 205; on the other hand, when cooperating with the pneumatic telescopic frame 202 to rise and fall, the height and angle of the stem can be flexibly adjusted according to the actual length of the stem or the operation requirements, which greatly improves the bud cutting accuracy and operation efficiency. The various components of the above-mentioned device are connected by bolts, screws or welding, and the structure is simple and compact, and disassembly and maintenance are convenient, while also ensuring the safety and stability of the stem during high-speed rotation.

[0049] The segmented tangential cutting rotary device 300 is used to perform tangential cutting and radial cutting on the surface of the tree trunk, and cuts multiple small segmented seedling bud tree segments at one time. It is used in conjunction with the tree trunk clamping and rotating device 200 as a whole to realize a high-efficiency bud cutting machine. The segmented chord cutting rotation device 300 is located above the tree trunk clamping rotation device 200, and includes a segmented chord cutting knife 301 and a tool rotation device that drives the segmented chord cutting knife 301 to rotate continuously 360° circumferentially. The rotation axis of the segmented chord cutting knife 301 is parallel to the axis of the clamped tree trunk. The segmented chord cutting knife 301 is located above the clamped tree trunk, and the length of the segmented chord cutting knife 301 is less than the distance between the left and right tree trunk clamping devices. The bottom end blade of the segmented chord cutting knife 301 is provided with a chord cutting horizontal knife 301a that can perform chord cutting on the clamped tree trunk, and the outer end of the upper surface of the chord cutting horizontal knife 301a is arranged with multiple segmented vertical knives 301b along the length direction.

[0050] The tool rotation device includes a tool shaft 302. The top end of the segmented chord cutter 301 is fixed to the tool shaft 302 by bolts, ferrules, or other connection methods. The tool shaft 302 is located above the tree stem to be clamped and parallel to the axis of the tree stem. The two ends of the tool shaft 302 are rotatably mounted on the operating platform 100. One end of the tool shaft 302 is also connected to the power output end of the tool drive motor 303. The rotation axis of the tool shaft 302 and the axis of the tree stem to be clamped are in the same vertical plane. The output end of the tool drive motor 303 is connected to a coupling. The coupling can be an elastic coupling or a rigid coupling. It not only ensures the efficiency and reliability of power transmission, but also compensates for slight installation errors that may exist between the motor output shaft and the tool shaft 302 to a certain extent, thereby maintaining the smooth rotation of the bud cutter. During operation, the coupling output by the tool drive motor 303 is transmitted to the tool shaft 302, which then drives the segmented chord cutter 301 to rotate at a preset speed to achieve the bud cutting operation on the tree stem.

[0051] See also Figure 6 The segmented chord cutting knife 301 includes a cutter head mounting plate 301c, the top of the cutter head mounting plate 301c is provided with a mounting sleeve 301d fixedly connected to the tool rotating device, the mounting sleeve 301d is fixed to the outside of the tool rotating shaft 302, the chord cutting horizontal knife 301a is provided on one side of the bottom end of the cutter head mounting plate 301c, the chord cutting horizontal knife 301a is perpendicular to the cutter head mounting plate 301c, and the chord cutting horizontal knife 301a is extended toward the axial direction of the tree trunk to be clamped, the outer end side of the chord cutting horizontal knife 301a is provided with a chord cutting blade for cutting into the surface of the tree trunk to be clamped, the segmented vertical knife 301b is perpendicular to the chord cutting horizontal knife 301a, and the outer end of the segmented vertical knife 301b is provided with a segmented blade for cutting into the surface of the tree trunk to be clamped, and the chord cutting blade and the segmented blade are both V-shaped blades.

[0052] The seedling bud collection device 400 is provided below the segmented chord cutting rotating device 300 and is used to collect the cut tree segments. The seedling bud collection device 400 includes a cut bud collection box 401 located below the segmented chord cutting knife 301. A collection box inclined baffle 402 is provided on one side of the cut bud collection box 401. The collection box inclined baffle 402 is located on the knife-out side of the segmented chord cutting knife 301. The height of the collection box inclined baffle 402 is higher than the cutting height of the segmented chord cutting knife 301. The collection box inclined baffle 402 is detachably connected to the cut bud collection box 401 through a matching block and a matching hole. The position and tilt angle can be changed by replacing the collection box inclined baffle 402, so that the falling path of the bud body can be fine-tuned, thereby improving the collection accuracy.

[0053] The cut bud collection box 401 can be fixed to the operating platform 100 by bolts, so that the collection box remains stable when the rubber seedlings fall in at high speed, avoiding displacement or loosening of the box body due to vibration or external force. In addition, if the collection box needs to be cleaned or repaired later, it can be quickly disassembled to improve maintenance efficiency.

[0054] In addition, when the bud cutter is running, the buds cut from the tree trunk will fall into the bud cutting collection box 401 due to inertia or gravity. Since the collection box is located in the middle area of ​​the operating platform 100 and there is enough operating space around it, workers can easily take out the buds in the box after the bud cutting operation is completed, and classify or transplant them. The collection box inclined baffle 402 and the upper edge of the bud cutting collection box 401 can be connected by hinges, hinges or rotating shafts, so that the collection box inclined baffle 402 can be flipped or tilted within a certain range. If it is found that the bud deviates from the collection area during the bud cutting process, the angle or position of the collection box inclined baffle 402 can be appropriately adjusted to fine-tune the bud path, thereby improving the collection accuracy.

[0055] The control operating system includes an emergency stop button, a trunk motor control button, a tool motor control button, a pneumatic telescopic cylinder 201 control button and a distribution box. The four components of the emergency stop button, the trunk motor control button, the tool motor control button, the pneumatic telescopic cylinder 201 control button and the distribution box are uniformly placed on one side of the operating platform 100. The three components of the emergency stop button, the trunk motor control button, the tool motor control button and the pneumatic telescopic cylinder 201 control button are placed side by side, and they and the distribution box are placed at the two corners of the operating platform 100 respectively, and their position is convenient for staff operation.

[0057] S1. Start the control operating system and check whether the tree stem clamping and rotating device 200 and the segmented tangential cutting rotating device 300 are functioning normally. At the same time, confirm whether the blade of the segmented tangential cutting knife 301 is sharp and whether the installation position of the seedling bud collecting device 400 is correct. If all devices function normally, proceed to the next step. Otherwise, immediately find the cause of the fault and repair it;

[0060] S4. During the first cutting, the trunk rotating device does not move, the segmented tangential cutting rotating device 300 is started, and the tool rotating device drives the segmented tangential cutting knife 301 to rotate.

[0061] S5, the tree trunk rotating device starts, drives the tree trunk to rotate 90 degrees and then stops. During this process, the segmented string cutter 301 is driven by the tool rotating device to continue to rotate. The state during the rotation process is shown in FIG. Figure 7 In (d), after rotating to the initial cutting position, the segmented string cutter 301 performs cutting again. The cutting state is shown in FIG. Figure 7 In (e), the state of cutting out the knife again is shown in Figure 7 Middle (f); the tree stem rotating device drives the tree stem to rotate intermittently in 90° increments until the tree stem completes a 360° rotation, achieving four full-circumference cuts; all cut tree segment seedling buds are collected in the seedling bud collection device 400;

[0062] S6. Turn off the tree stem rotating device and the segmented chord cutting rotating device 300, release the fixation of the tree stem, take out the tree stem that has completed bud cutting, and return the height adjustment device to the initial position to prepare for the next bud cutting operation.

5. A method for controlling a rubber seedling budding segmented rotary bud cutting machine, using a rubber seedling budding segmented rotary bud cutting machine according to any one of claims 1 to 4, characterized in that: The following steps are involved: S1. Start the control system and check whether the tree stem clamping and rotating device, the segmented tangential cutting and rotating device, and the seedling bud collecting device are functioning properly. If the devices are functioning properly, proceed to the next step; otherwise, perform repairs immediately. S2, select the rubber tree stem of appropriate length, clamp and fix it by two tree stem clamping rotating devices; S3. Adjust the height of the tree stem by the height adjustment device to ensure the cutting distance between the tree stem and the segmented string cutter; S4. The segmented tangential cutting rotating device is started, and the tool rotating device drives the segmented tangential cutting knife to rotate. When the rotation contacts the surface of the tree stem, the tangential cutting horizontal knife cuts the surface of the tree stem tangentially, and the segmented vertical knife cuts the surface of the tree stem radially. After the cutting is completed, the surface of the tree stem will be cut into multiple small segments. The cut seedling bud tree segments automatically fall into the seedling bud collection device under the action of inertia and gravity, and the cutting is completed in one step; S5. The stem rotation device starts, driving the stem to rotate 90° and then stops. During this process, the segmented chord cutter is driven by the tool rotation device to continue rotating. When it rotates back to the initial cutting position, the segmented chord cutter cuts again. The stem rotation device drives the stem to rotate intermittently in 90° increments until the stem completes a 360° rotation, achieving four full-circle cuts. All cut tree buds are collected in the bud collection device. S6. Turn off the tree stem rotation device and the segmented chord cutting rotation device, release the fixation of the tree stem, and take out the tree stem that has completed bud cutting; and return the height adjustment device to the initial position to prepare for the next bud cutting operation.
