Description

Technical Field

[0001] The invention relates to the field of seedling cultivation, and 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 main source of natural rubber in the world, and their planting and cultivation are crucial to the development of the rubber industry. In order to ensure the breeding of high-quality rubber tree varieties, increase rubber production and enhance disease resistance, budding propagation technology is widely used. Budding is an asexual propagation method that grafts buds from excellent mother trees onto rootstocks to grow them into plants with excellent traits. This technology can maintain the excellent genetic characteristics of rubber trees, shorten the growth cycle, and increase the survival rate of seedlings. It is one of the key links in the modern rubber planting industry.

[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 chipped 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, thus 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 clamping device, a rotary cutting device, a lower hopper and a control device, the frame is the carrier of the entire bud extracting machine, the clamping device, the rotary connection 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 clamping device, and then the clamping pads are driven by the clamping electric cylinder to clamp 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 to extract the bud, and the cut bud falls from the rectangular groove to the lower hopper and slides out. Although the 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 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 the field. Summary of the invention

The collection box inclined baffle is located on the knife outlet side of the segmented chordal cutter, and the height of the collection box inclined baffle is higher than the cutting height of the segmented chordal cutter.

[0015] 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: S1. Start the control operating system and check whether the tree stem clamping rotating device, the segmented tangential cutting rotating device and the seedling bud collecting device are normal. If each device functions normally, proceed to the next step, otherwise, immediately perform maintenance; S2, select a rubber tree stem of suitable length, and clamp and fix it by two tree stem clamping rotating devices; S3, adjusting the height of the tree stem by a 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 performs tangential cutting on the surface of the tree stem, and the segmented vertical knife performs radial cutting on the surface of the tree stem.

[0017] 2. The present invention provides a rotary bud cutting method, in which the rotation axis of the tool is parallel to the axis of the tree trunk, and horizontal chord cutting can be achieved. At the same time, combined with the characteristics of the tree stem intermittently rotating circumferentially in 90° increments, it is used to meet the 360° full-circle cutting of the tree stem; at the same time, combined with the segmented bud cutting method, vertical segmented cutting can be achieved, 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.

[0018] 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 the present 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 the bud bag, and then the required seedling bud tree segment can be selected. This method can greatly improve the bud cutting production efficiency.

[0019] 4. The present invention introduces a height adjustment device to achieve precise adjustment of the height and position of the tree trunk, ensuring that the cutter is always in the best cutting state. The flexible adjustment mechanism is suitable for tree trunks of various specifications and can accurately set the cutting distance to ensure that each bud is completely cut.

DETAILED DESCRIPTION

[0021] The present invention is further described below in conjunction with the accompanying drawings and examples. In the following detailed description, certain exemplary embodiments of the present invention are described only by way of illustration. Needless to say, those of ordinary skill 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 protection of the claims.

[0022] like Figures 1 to 5 As shown, a rubber seedling bud grafting segmented rotary bud cutter comprises 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.

[0023] The operating platform 100 is placed horizontally and fixed on the ground to prevent the bud cutter from tipping over due to an unstable center of gravity.

[0024] The tree stem clamping and rotating device 200 is used to clamp and fix the tree stem, and drives the tree stem to intermittently rotate axially in increments of 90°, so as to meet the requirements of 360° full-circle cutting of the tree stem. The tree stem clamping and rotating device 200 includes height adjustment devices arranged at the left and right ends of the operating platform 100, and the telescopic end of the height adjustment device is 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 increments of 90°. The two tree stem clamping devices are arranged opposite to each other on the left and right sides and are used to horizontally clamp the two 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 diameter of the clamped tree stem is greatly different, the position of the tree stem after being clamped and the cutting tool will change accordingly. In order to ensure the requirement of four full-circle cuts intermittently in 90° increments, it is necessary to adjust the height of the tree stem so that the cutting position between the tool and the tree stem is accurate. At the same time, when cutting, since the tool is cutting in an arc around the center of the circle, the cutting line formed on the surface of the tree stem is an arc, which will cause the amount of tree cutting to be too large. Therefore, during the cutting process, the height adjustment device will correspondingly move downward a small amount and then gradually move upward a small amount in the vertical direction, that is, drive the tree stem to slightly adjust downward first and then slightly adjust upward, to change the cutting position between the tool and the tree stem, thereby minimizing the amount of tree cutting 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.

[0025] The height adjustment device includes a pneumatic telescopic cylinder 201, the cylinder end of the pneumatic telescopic cylinder 201 is fixedly mounted on the operating platform 100, and a pneumatic telescopic frame 202 is vertically fixed to the telescopic end of the pneumatic telescopic cylinder 201, and the tree stem clamping device and the tree stem rotating 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 the pneumatic telescopic cylinder 201 from shaking.

[0026] The tree stem clamping device includes a clamping jaw chuck 203, the outer fixed end of the clamping jaw chuck 203 is fixedly connected to a chuck rotating shaft 204, and the chuck rotating shaft 204 is installed on the pneumatic telescopic frame 202 through a bearing seat; the tree stem rotating device includes a motor mounting frame fixed to the pneumatic telescopic frame 202, and a tree stem driving motor 205 is installed on the motor mounting frame, and the power output end of the tree stem driving motor 205 is transmission-connected to the chuck rotating shaft 204 through a coupling. The clamping jaw chuck 203 is a prior art product and will not be described in detail here.

[0027] 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, so as to achieve a stable clamping of stems of different thicknesses. When the stem drive motor 205 is started, its output shaft drives the coupling and the clamping jaw chuck 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 adjustable position 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, etc., with a simple and compact structure, convenient disassembly and maintenance, and also ensures the safety and stability of the stem during high-speed rotation.

[0028] The segmented tangential cutting rotating 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 rotating device 200 as a whole to achieve a high-efficiency bud cutting machine. The segmented chord cutting rotating device 300 is located above the tree trunk clamping rotating device 200, and includes a segmented chord cutting knife 301 and a tool rotating device that drives the segmented chord cutting knife 301 to continuously rotate 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.

[0029] The tool rotating device includes a tool shaft 302. The top 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. Both 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 is in the same vertical plane as the axis of the tree stem to be clamped. 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, which not only ensures the efficiency and reliability of power transmission, but also compensates for the slight installation error 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 outputted by the tool driving motor 303 is transmitted to the tool rotating shaft 302, and then drives the segmented string cutter 301 to rotate at a preset speed to achieve the bud cutting operation on the tree stem.

[0030] See also Figure 6The 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 cutter rotating device, the mounting sleeve 301d is fixedly sleeved on the outside of the cutter 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 stem 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 stem 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 stem to be clamped, and the chord cutting blade and the segmented blade are both V-shaped blades.

[0031] The seedling bud collection device 400 is arranged 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, and 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 exit side of the segmented chord cutting knife 301, and 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 matching blocks and matching holes. The position and inclination 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.

[0032] 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 also be quickly disassembled to improve maintenance efficiency.

[0033] In addition, when the bud cutter is running, the buds cut from the tree stems 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.

[0034] The control operating system includes an emergency stop button, a tree 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 tree 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 tree 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 two corners of the operating platform 100 respectively, and their positions are convenient for staff to operate.

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. When the rotation contacts the surface of the trunk, the tangential cutting transverse knife 301a performs tangential cutting on the surface of the trunk.

8. A rubber seedling bud grafting segmented rotary bud cutting machine as claimed in claim 1, characterized in that: The seedling bud collection device includes a cut bud collection box located below the segmented chordal cutter, 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 outlet side of the segmented chordal cutter, and the height of the collection box inclined baffle is higher than the cutting height of the segmented chordal cutter.

9. A method for controlling rubber seedling bud grafting segmented rotary bud cutting, using a rubber seedling bud grafting segmented rotary bud cutting machine as claimed in any one of claims 1 to 8, characterized in that: The following steps are involved: S1. Start the control operating system and check whether the tree stem clamping rotating device, the segmented tangential cutting rotating device and the seedling bud collecting device are normal. If each device functions normally, proceed to the next step, otherwise, immediately perform maintenance; S2, select a rubber tree stem of suitable length, and clamp and fix it by two tree stem clamping rotating devices; S3, adjusting the height of the tree stem by a 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 performs tangential cutting on the surface of the tree stem, and the segmented vertical knife performs radial cutting on the surface of the tree stem. After the cutting is completed, the surface of the tree stem will be cut into multiple small segments, and the cut seedling bud tree segments will automatically fall into the seedling bud collecting device under the action of inertia and gravity, and the cutting is completed at one time; S5. The tree stem rotating device starts, drives the tree stem to rotate 90° and then stops. During this process, the segmented string cutter is driven by the tool rotating device to continue rotating. When it rotates back to the initial cutting position, the segmented string cutter cuts again. 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-circle cuts. All the cut tree segment seedling buds are collected in the seedling bud collection device. S6. Turn off the tree stem rotating device and the segmented chord cutting rotating 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.
