Description

Technical Field

[0001] The invention relates to the technical field of pepper planting, and in particular to a pepper shaping device and a shaping and cultivation method. Background Art

[0002] As an important economic tree species, Sichuan pepper plays a key role in industrial development in karst mountainous areas such as Zunyi City in Guizhou Province. To improve the quality and efficiency of low-yield pepper orchards, a demonstration base for the conversion of low-yield Sichuan pepper forests was established in Wuchuan Autonomous County, Zunyi City. A new high-quality Sichuan pepper variety, "Yinhongjiao," suitable for the local environment, was successfully approved. This variety boasts robust vigor, vigorous branching, and excellent yields. Its standardized tree shape (primarily adopting a natural open-heart shape) is crucial for ensuring high and stable yields. "Branch pulling," a core pruning technique, is crucial for regulating the angle of main branch opening, optimizing tree structure, and promoting flower bud differentiation and fruit quality.

[0003] However, the traditional pulling branch technology currently used in pepper cultivation has the following significant defects: (1) Interference with field management: Traditional methods rely mainly on ropes (such as wire, cloth strips, and plastic ropes) to pull branches. During operation, one end of the rope must be fixed to the main branch and the other end must be fixed to the ground (such as a wooden stake or stone). After pulling branches, the fixed points and ropes spread throughout the field greatly hinder subsequent routine agricultural operations such as spraying, tillage, and weeding, reducing overall operational efficiency.

[0004] (2) Poor stability and high maintenance cost: The rope material is very easy to loosen, fall off or even break under irrigation, rainfall or external force. To ensure the pulling effect, frequent inspection, re-binding and fixing are required, which significantly increases the labor intensity and subsequent maintenance costs.

[0005] (3) Prone to mechanical damage: During the branch pulling operation, due to improper force or insufficient branch toughness, branches often break or split, directly damaging the tree and affecting tree recovery and yield formation.

[0006] These defects restrict shaping effectiveness and production efficiency, increasing production costs and labor intensity while also directly impacting the establishment of Sichuan pepper tree shapes, the achievement of early high-yield goals, and the ease of orchard management. Therefore, there is an urgent need to develop a new Sichuan pepper branch pulling method and supporting device that minimizes interference, offers high stability, and effectively reduces mechanical damage, in order to overcome the shortcomings of existing technologies and meet the needs of standardized and refined development in the Sichuan pepper industry.

[0019] (4) High adaptability: The main and auxiliary support rods can be freely adjusted in length to accommodate main branches of different thicknesses, positions, and growth stages, as well as plants with different spacing. The sleeve can slide and rotate on the center ring, making it easy to accurately position the support mechanism on the main branches in all directions, adapting to the different directions of the natural growth of the red pepper.

[0020] (5) Good versatility and durability: The main support rod, auxiliary support rod and vertical rod adopt the same telescopic structure, and the locking device is also designed to be the same or optional type. The parts are highly versatile and easy to manufacture, maintain and replace. They can be reused for different plants or different years, reducing long-term investment costs.

[0021] In summary, the red pepper shaping device and method described in the present invention not only significantly improve the shaping effect (standardized tree shape and uniform lighting), effectively protect the health of the plants, but also greatly improve the convenience and efficiency of operation, promote the high quality and high yield of red peppers, and reduce labor costs and equipment losses.

Example 1

[0037] like Figure 1-Figure 7 As shown, this embodiment provides a red pepper shaping device, including a central ring 1 and at least two spreading mechanisms connected to the central ring 1. The main branches remaining in the red pepper are usually 3-4, and the corresponding spreading mechanisms are four. This embodiment takes four main branches and four spreading mechanisms as an example.

[0038] The center ring 1 is a smooth circular ring, and all the expansion mechanisms are concentrated on the center ring 1 through the sleeve 2 to form an integral frame.

[0039] Each expansion mechanism includes a sleeve 2 , a main support frame 3 and a secondary support frame 4 .

[0040] The sleeve 2 is sleeved on the center ring 1 and can slide and rotate along the center ring 1 (the rotation is for easy storage before installation), so that the expansion mechanism can be accurately positioned on the main branches in all directions to adapt to the different directions of natural growth of the red pepper. A locking screw 5 is threadedly connected to the sleeve 2 for locking the sleeve 2 on the center ring 1.

[0041] like Figure 4 and Figure 5 As shown, the main support frame 3 includes a main support rod 31, a first locking device 32 and a main support assembly 33. The main support rod 31 is a telescopic rod laterally fixed to the side wall of the sleeve 2, and its front end can be freely extended and retracted. A first cylindrical hole 311 is preset at the front end (inside) of the main support rod 31; the main support rod 31 can freely adjust the length to adapt to main branches of different thicknesses, different positions, different growth stages, and plants with different spacing. The first locking device 32 is installed on the main support rod 31 and can lock the front end of the main support rod 31 to limit its extension and retraction. The main support assembly 33 is installed on the front end of the main support rod 31, and its front end is a V-shaped or U-shaped structure that can be forked on the main branch of the red pepper; specifically, as Figure 6 As shown, the structure of the main support assembly 33 is as follows: the main support assembly 33 includes a nut 331, a main support leg 332, a buffer spring 335 and a pressure plate 333; the nut 331 is threadedly connected to the front end of the main support rod 31 (telescopic end), and a first center hole with a diameter smaller than the first cylindrical hole 311 and connected to the first cylindrical hole 311 is provided in the middle thereof; the main support leg 332 is movably sleeved in the first cylindrical hole 331 and the first center hole, and the front end of the main support leg 332 is located outside the nut 331 and is fixed with a V-shaped or U-shaped fork rod 334 that can be forked on the main branch of the red pepper, and the fork rod 334 is directly forked on the upper part of the straight section of the main branch, providing A stable support point, an elastic pad is fixed on the side of the fork rod 334 that contacts the main branch; the buffer spring 335 is sleeved in the first cylindrical hole 311 and its diameter is larger than the first center hole. The buffer spring 335 can absorb the impact force during operation and the slight displacement caused by the growth of the main branch or external force (such as wind), effectively avoiding the rigid support causing crushing, abrasion or ring cutting on the main branch epidermis, and protecting the health of the tree; the pressure plate 333 is movably arranged in the first cylindrical hole 311 and fixedly connected to the rear end of the main support leg 332. The pressure plate 333 is located between the buffer spring 335 and the nut 331 and its diameter is larger than the outer diameter of the buffer spring 335.

[0042] like Figure 4 and Figure 5As shown, the secondary support frame 4 includes a secondary support rod 41, a second locking device 42 and a secondary support assembly 43. The secondary support rod 41 is a telescopic rod that is obliquely fixed on the side wall of the sleeve 2 on the lower side of the main support rod 31. Its front end can be freely extended and retracted. A second cylindrical hole 411 is preset at the front end (inside) of the secondary support rod 41. The secondary support rod 41 can freely adjust its length to adapt to main branches of different thicknesses, different positions, and different growth stages, as well as plants with different spacings. The secondary support rod 41 cooperates with the main support rod 31 to act together on the lower and upper parts of the same straight section of the same main branch to achieve reliable and stable support. The second locking device 42 is installed on the secondary support rod 41 and can lock the front end of the secondary support rod 41 (telescopic end) to limit its movement; the secondary support assembly 43 is connected to the front end of the secondary support rod 41 through an elastic member, and its front end is a C-shaped structure that can be stuck on the main branch of the red pepper. Specifically, as shown Figure 7As shown, the structure of the auxiliary support assembly 43 is as follows: the elastic member is a buffer spring 2 436; the auxiliary support assembly 43 includes a nut 2 431, an auxiliary support foot 432, a pressure rod 433, a pressure plate 2 435 and a pressure plate 3 437; the nut 431 is threadedly connected to the front end of the auxiliary support rod 41, and a second center hole with a diameter smaller than the second cylindrical hole 411 and connected to the second cylindrical hole 411 is provided in the middle of the nut 431; the auxiliary support foot 432 is movably sleeved in the second cylindrical hole 411 and the second center hole, and the front end of the auxiliary support foot 432 is located outside the nut 2 431 and is fixed with an L-shaped pull rod 434 that can hook the main branch of the red pepper, and the L-shaped pull rod 434 is arc-shaped toward the pressure rod 433 and is provided with an elastic pad; the pressure rod 433 is L-shaped, and its vertical The segment (cylindrical) is slidably sleeved outside the auxiliary support foot 432 and is also movably sleeved in the second cylindrical hole 411 and the second center hole. The pressure rod 433 is arc-shaped on the side facing the L-shaped pull rod 434 and is provided with an elastic pad. The transverse section of the pressure rod 433 is located outside the nut 431 and cooperates with the L-shaped pull rod 434 to form a C-shaped slot. The slot is trumpet-shaped, which is convenient for inserting the main branch. The slot formed by the L-shaped pull rod 434 and the pressure rod 433 is used to hook the lower part of the main branch. The auxiliary support assembly 43 and the main support assembly 33 are fixed at two points in the upper and lower parts, which effectively prevents the main branch from rebounding or shifting after opening. At the same time, the main branch is pulled by the L-shaped pull rod 434 and the buffer spring 436, reducing the instantaneous stress of the main support rod 31 on the main branch during the process of opening the main branch, thereby reducing the risk of branch splitting or damage. The second pressure plate 435 is slidably mounted on the outside of the auxiliary support leg 432 and fixed on the rear end of the vertical section of the pressure rod 433 located in the second cylindrical hole 411. The diameter of the second pressure plate 435 is larger than the second center hole; the third pressure plate 437 is fixed on the rear end of the auxiliary support leg 432 located in the second cylindrical hole 411; the second buffer spring 436 is mounted on the outside of the auxiliary support leg 432 and located between the second pressure plate 435 and the third pressure plate 437. The diameter of the second buffer spring 436 is smaller than the diameter of the second pressure plate 435 and the third pressure plate 437. The second buffer spring 436 can absorb the impact force during operation and the slight displacement caused by the growth of the main branch or external force (such as wind), effectively avoiding the compression, abrasion or ring cutting of the main branch epidermis caused by rigid support, thereby protecting the health of the tree. Example 2

[0043] The difference between this embodiment and embodiment 1 is that: like Figure 1 and Figure 3 As shown, the red pepper shaping device also includes a horizontally arranged connecting rod 6 and a vertically arranged upright rod 7.

[0044] The ends of the connecting rod 6 are connected to the sleeves 2 of the two expansion mechanisms via locking screws 5. The top of the vertical rod 7 is fixedly connected to the bottom of the connecting rod 6, and the lower end of the vertical rod 7 is inserted into the soil layer next to the main trunk of the red pepper. The vertical rod 7 is a telescopic rod with an adjustable end that can be retracted and locked by a third locking device. The vertical rod 7 is inserted into the soil layer, providing a stable base support for the entire device, adapting to different trunk heights and terrains.

[0045] In this embodiment, a connecting rod 6 transversely connects the sleeves 2 of the two expansion mechanisms, and a vertical rod 7 vertically supports the connecting rod 6 and is inserted into the soil, greatly enhancing the rigidity and anti-lodging ability of the entire device, ensuring that the shaping effect can be maintained long-term under external forces such as wind and rain. The provision of the vertical rod 7 also improves the convenience of operating the expansion mechanism. After the vertical rod 7 supports the entire device, each expansion mechanism can be easily operated to perform the shaping operation.

[0046] like Figure 8 As shown, the main support rod 31, the secondary support rod 41 and the vertical rod 7 have the same structure, and are all composed of a fixed rod 9 and a telescopic rod 10. The fixed rod 9 is a hollow tube, and a guide groove 11 connected to the interior of the fixed rod 9 is provided along its length direction; the telescopic rod 10 is slidably mounted in the fixed rod 9 and one end of the telescopic rod 10 can slide out of the fixed rod 9. Example 3

[0047] The difference between this embodiment and embodiment 2 is that: like Figure 1 and Figure 3 As shown, an annular support plate 8 is fixed on the outside of the vertical pole 7, and the lower surface of the annular support plate 8 is in contact with the surface of the soil layer beside the main trunk of the red pepper.

[0048] The annular support plate 8 increases the contact area with the ground, significantly dispersing the pressure exerted by the pole 7 on the soil, effectively preventing the pole 7 from sinking. This ensures the long-term stability of the device height and main branch opening angle, reducing the need for frequent adjustments. With the annular support plate 8 providing the primary support, the pole 7 only needs to be shallowly inserted into the soil, or simply stabilized by the plate, to avoid direct damage to the root system caused by deep insertion of the pole 7. Example 4

[0049] The difference between this embodiment and embodiment 3 is that: The first locking device 32, the second locking device 42, and the third locking device are all locking bolts. The screws of these locking bolts extend into the guide slot 11 and threadably connect to the telescopic rod 10, thereby locking the telescopic rod 10 within the fixed rod 9. After adjusting the lengths of the main support rod 31, the secondary support rod 41, and the telescopic ends of the vertical rod 7, tightening the locking bolts secures the main support rod 31, the secondary support rod 41, and the vertical rod 7. However, the locking bolts are prone to rust and dust accumulation over time, making them difficult to tighten, which is detrimental to the subsequent use of the red pepper shaping device and also requires considerable effort to tighten. Example 5

[0050] This embodiment aims to overcome the differences of Example 4. The differences between this embodiment and Example 3 are: The first locking device 32, the second locking device 42 and the third locking device have the same structure and are all composed of locking mechanisms. Figure 8-10 As shown, the locking mechanism includes a lock plate 12, a movable box 14, a connecting bolt 16, a return spring 17 and a handle 18, all of which are made of stainless steel. The return spring 17 is enclosed in the movable box 14 to extend the service life in a humid environment.

[0051] The locking plate 12 is fixed on the fixing rod 9 along the length direction of the fixing rod 9, and a plurality of locking holes 13 are provided on the locking plate 12 along the length direction of the fixing rod 9. The locking holes 13 are evenly distributed on the locking plate 12 to form a scale-type positioning point to ensure that the telescopic amount of the telescopic rod 10 can be quantified.

[0052] The movable box 14 is arranged above the guide groove 11 and is hollow inside. A latch 15 is vertically fixed at a position above the lock plate 12 at the bottom of the movable box 14. The latch 15 can slide along the guide groove 11 with the movable box 14 to the top of any one of the lock holes 13 and then be inserted into the lock hole 13. The fitting clearance between the latch 15 and the lock hole 13 is ≤0.5mm. After the latch 15 is inserted into the lock hole 13, a mechanical hard connection is formed, which is more resistant to vibration than friction locking (such as bolt tightening), preventing loosening during field operations. The latch 15 also resists the axial thrust and radial torsion of the telescopic rod 10 to avoid slipping due to the tension of the main branch.

[0053] The connecting bolt 16 is vertically arranged in the movable box 14. After the screw portion thereof moves downward and penetrates the bottom of the movable box 14, it extends into the guide groove 11 and is fixedly connected to the telescopic rod 10 and can slide back and forth along the guide groove 11 with the telescopic rod 10.

[0054] The return spring 17 is located in the movable box 14 and is sleeved outside the screw of the connecting bolt 16. The diameter of the return spring 17 is smaller than the diameter of the head of the connecting bolt 16. It is used to press the movable box 14 onto the fixed rod 10 and keep the pin 15 inserted into the lock hole 13.

[0055] The handle 18 is fixed above the movable box 14. When the handle 18 is pulled up, the movable box 14 can be pulled up to overcome the elastic force of the return spring 17, so that the latch 15 leaves the lock hole 13. Then, the movable box 14 is rotated, and the latch 15 can be inserted into the guide groove 11 and slide back and forth along the guide groove 11 with the movable box 14.

[0056] The unlocking steps for the first, second, and third locking devices of this embodiment are as follows: Lifting the handle 18 causes the movable box 14 to overcome the force of the return spring 17, allowing the latch 15 to disengage the lock hole 13, thereby unlocking the device without the need for tools. After unlocking, simply rotating the movable box 14 so that the latch 15 engages the guide slot 11 allows the telescopic rod 10 to slide freely, achieving stepless length adjustment. This seamlessly integrates with the sliding adjustment, allowing the first, second, and third locking devices 32, 42, and 43 to slide without having to constantly lift the handle 18.

[0057] The relocking steps of the first locking device 32, the second locking device 42, and the third locking device of this embodiment are as follows: after the telescopic rod 10 is adjusted into position, if the latch 15 is not inserted into the guide groove 11 at this time, the latch 15 is aligned with the nearest lock hole 13 directly below it, and then the handle 18 is directly released, and the return spring 17 automatically presses down the movable box 14, and the latch 15 is automatically inserted into the nearest lock hole 13 instantly, thereby achieving locking. After the telescopic rod 10 is adjusted into position, if the latch 15 is inserted into the guide groove 11 at this time, the handle 18 is lifted, and the movable box 14 is moved upward to overcome the elastic force of the return spring 14, and the latch 15 is disengaged from the guide groove 11. The movable box 14 is then directly rotated to move the latch 15 back to the top of the lock plate 12, and the latch 15 is aligned with the nearest lock hole 13 directly below it. The handle 18 is then released, and the return spring 17 automatically presses down the movable box 14, and the latch 15 is automatically inserted into the nearest lock hole 13 instantly, thereby achieving locking.

[0058] This structure simplifies the complex "loosen-adjust-lock" process in Example 4 into three simple steps: "pull-slide-release," adapting to high-frequency adjustments. The latch 15 is mechanically locked in the keyhole 13, fundamentally resolving issues like thread slippage and rusting of the locking bolt, ensuring a long-lasting and stable shaping effect. Example 6

[0059] The shaping and cultivation method using the red pepper shaping device described in any one of Examples 1-5 comprises the following steps: S1. Loosen the locking screws 5 of all the expansion mechanisms to release the fixed constraints between the sleeve 2 and the center ring 1, so that the sleeve 2 can slide and rotate freely, reserving operating space for subsequent precise positioning of the main branch.

[0060] S2. Release the first locking device 32 and the second locking device 42 of all the expansion mechanisms, so that the front ends of the main support rod 31 and the auxiliary support rod 41 are in a free telescopic state, so that the front ends of the main support rod 31 and the auxiliary support rod 41 (telescopic rod 10) enter a stepless telescopic state to adapt to the diameters and spatial positions of different main branches.

[0061] S3. The adjustment process of one of the expansion mechanisms is as follows: S31. Stretch the front end of the secondary strut 41 of the expansion mechanism until the secondary strut 41 reaches an appropriate length, and preliminarily set the operating radius of the secondary support assembly 43 so that the length of the secondary strut 41 is approximately equal to the distance from the lower part of the main branch to the center ring, ensuring that the C-shaped slot can hook the main branch to avoid slipping due to oblique pulling.

[0062] S32. Slide the sleeve 2 along the center ring 1 so that the secondary support rod 41 of the expansion mechanism is aligned with the lower part of the straight section of a main branch, and then the secondary support component 43 with a C-shaped structure at the front end of the secondary support rod 41 is clamped on the corresponding main branch to form a secondary support point. During this process, the card slot of the C-shaped structure adaptively fits into the main branch to form a bottom anchor point to prevent the device from shifting when the main branch is pressed down.

[0063] S33. Then stretch the front end of the main support rod 31 of the spreading mechanism respectively, so that the main support component 33 (fork rod 334) with a V-shaped or U-shaped structure at the front end of the main support rod 31 is forked on the upper part of the straight section of the corresponding main branch, tighten the locking screws 5 of the two spreading mechanisms (freeze the position of the sleeve 2 to ensure that the spreading mechanism no longer slides or rotates during subsequent operations), form a main support point and preliminarily fix the position of the spreading mechanism. After the V-shaped or U-shaped fork rod 334 is forked into the upper part of the main branch, it forms an upper and lower double-point constraint with the secondary support point to form a stable force system.

[0064] S34. Initial opening of the main branches: Then push the front end of the main support rod 31 of the spreading mechanism forward. The main support rod 31 drives the fork rod 334 to press the corresponding main branch to open outward 30-35 degrees, and then lock the second locking device 42 (that is, lock the secondary support rod 41, fix the bottom fulcrum, and prevent the main branch from rebounding) to achieve the initial opening of the main branch. 30-35 degrees is the safety threshold for elastic deformation of the branch, which avoids opening 45 degrees at a time and causing the wood to tear.

[0065] S35. Fine-tune to the optimal angle: Continue to push forward the front end of the main support rod 31 of the expansion mechanism. The main support rod 31 continues to drive the fork rod 334 to press the corresponding main branch to open outward again by 5-10°, then lock the first locking device 32 (lock the main support rod 31 to complete rigid fixation and form an active force application point at the top), and add 5-10° to overcome branch creep rebound. The total angle reaches 35-45° (ideal fruiting branch angle). The reasonable opening angle improves the lighting and ventilation conditions in the inner cavity of the crown, which is beneficial to leaf photosynthesis, flower bud differentiation, fruit coloring and quality improvement, while reducing the incidence of diseases and insect pests; that is, the adjustment of an expansion mechanism and the shaping of a main branch are completed.

[0066] S4. Repeat steps S31-S35 of S3 to adjust other opening mechanisms and shape other main branches, ensure that the opening angles and force of all main branches are uniform, avoid crown deviation, and each opening mechanism corresponds to the main branch one by one, thus completing the adjustment of all opening mechanisms and the shaping of all main branches.

[0067] S5. When making adjustments, first adjust two of the expansion mechanisms synchronously, and then adjust the other main expansion mechanisms separately. Synchronously adjust the two points (expansion mechanisms) first to establish a preliminary stability benchmark (establish a basic stability framework) for the entire device, and then adjust the remaining main branches one by one. This method makes the operation more orderly and less likely to cause the device to become unstable.
