Description

Technical Field

[0001] This utility model relates to the field of agricultural planting equipment, and in particular to a portable transplanting root protection pot for chili seedling cultivation. Background Technology

[0002] In the process of transplanting chili seedlings, root-protecting pots are often used for planting and transporting seedlings to protect their root systems and improve survival rates. Root-protecting pots, as a common seedling container, are usually made of biodegradable or rigid materials and have a certain structural strength to maintain the integrity of the root ball. In practical applications, root-protecting pots need to balance portability, air permeability, water retention, and ease of demolding during transplanting. Existing root-protecting pots are mostly fixed structures with relatively uniform shapes and sizes. During transplanting, additional tools are often needed to assist in removing the pots or manually adjusting the root system, which increases the number of steps involved. Furthermore, some root-protecting pots lack effective carrying structures during transportation or handling, making them inconvenient to carry, especially in field operations, and affecting operational efficiency. Therefore, there is still room for improvement in the portability design and ease of transplanting of existing root-protecting pots. Utility Model Content

[0003] The purpose of this utility model is to provide a portable transplanting root protection pot for chili seedling cultivation, which solves the problems mentioned in the background art.

[0004] This utility model is implemented as follows: a portable transplanting root protection pot for chili seedling cultivation includes a main pot body, a side-opening and closing structure, a bottom detachment mechanism, and a carrying component, wherein:

[0005] The main pot is cylindrical and consists of two sections: the upper section is the seedling cavity and the lower section is the support base. The outer wall of the seedling cavity has longitudinally distributed ventilation slits, and the bottom of the support base has an annular flange with a stepped snap-fit ​​surface on the inner side for engaging with the bottom release mechanism. The inner wall of the seedling cavity is coated with a slow-release water-retaining coating, which is made of a mixture of natural cellulose and bentonite and has a thickness of 0.5 mm to 1.2 mm.

[0006] The lateral opening and closing structure is located on the outside of the seedling cavity of the main pot body. It includes a pair of symmetrically arranged arc-shaped movable plates, a hinge shaft, and a locking protrusion. The arc-shaped movable plates extend along the height direction of the main pot body, with their inner surfaces fitting against the outer wall of the seedling cavity and their outer surfaces having anti-slip textures. The hinge shaft is fixed at the connection between the top of the arc-shaped movable plate and the top of the supporting base, allowing the arc-shaped movable plate to rotate outward around the shaft. The locking protrusion is located in the middle of the inner side of the arc-shaped movable plate and engages with the corresponding groove on the outer wall of the main pot body to achieve positional fixation in the closed state.

[0007] The bottom detachment mechanism includes a bottom tray, lifting claws, and an elastic reset plate. The bottom tray is a circular flat plate with a diameter slightly smaller than the inner diameter of the support base, and its edge has four equidistant notches. The lifting claw is an L-shaped metal plate, one end of which is fixed to the bottom of the inner wall of the support base, and the other end extends upward and inserts into the notch of the bottom tray. The top of the claw has a sloping guide structure. The elastic reset plate is an arc-shaped spring steel plate, with both ends riveted to the inner wall of the support base and the bottom surface of the bottom tray, respectively. Under normal conditions, it lifts the bottom tray so that it is in contact with the stepped surface of the support base.

[0008] The carrying assembly includes a folding lifting rod, a pivot seat, and a limiting baffle. The folding lifting rod consists of two straight rods connected by a central pivot, with damping washers on both sides of the pivot. The pivot seat is a U-shaped bracket, fixed symmetrically to the outside of the main bowl support base, with its opening facing upwards to accommodate the end of the folding lifting rod. The limiting baffle is welded to the inside of the pivot seat to limit the unfolding angle of the folding lifting rod to 120 degrees, preventing excessive unfolding that could lead to structural failure.

[0009] Furthermore, a flexible sealing strip is provided on the inner side of the arc-shaped movable plate. The sealing strip is bonded along the length of the plate and is made of silicone. The cross-section is semi-circular and the height is consistent with the wall thickness of the main bowl. When the arc-shaped movable plate is closed, it fills the gap and reduces moisture evaporation.

[0010] Furthermore, the upper surface of the bottom tray is provided with radial drainage grooves, which are 0.8 mm deep and 1.5 mm wide, extending from the center to the edge, to guide excess water to the side wall and prevent water accumulation at the roots.

[0011] Furthermore, the inclined guide structure of the lifting claw has an inclination angle of fifteen degrees, which generates a downward component force when it contacts the edge of the bottom tray notch, making it easy to release the lock when external pressure is applied; the claw material is stainless steel, and the surface is passivated, making it corrosion-resistant and wear-resistant.

[0012] Furthermore, the elastic reset piece has a stress relief hole in the middle with a diameter of 3.5 mm, which is used to reduce metal fatigue caused by repeated bending and extend service life; the initial bending angle of the reset piece is 30 degrees, providing stable upward support force.

[0013] Furthermore, the two straight sections of the folding lifting rod are equipped with spherical grip heads at their ends, and the grip heads are covered with rubber sleeves. The surface of the rubber sleeves is pressed with diamond-shaped anti-slip textures to improve grip comfort. The straight rods have a hollow internal structure with a wall thickness of 1.2 millimeters, which reduces the overall weight.

[0014] Furthermore, the bottom of the pivot seat is provided with a reinforcing rib, which extends vertically, with a height of one-third of the height of the main bowl and a width twice the thickness of the pivot seat, thereby enhancing the structural rigidity during lifting.

[0015] Furthermore, the outer wall of the main bowl support base is provided with a positioning boss, which is located below the pivot seat and is used to abut against the lower section of the lifting rod when the folding lifting rod is retracted to prevent it from swinging freely.

[0016] Furthermore, the locking protrusion has a trapezoidal cross-section, wider at the top and narrower at the bottom, forming a wedge-shaped fit with the groove on the outer wall of the main bowl. In the closed state, it relies on gravity to self-lock; the top of the protrusion is provided with a finger groove for inserting a finger to release the lock.

[0017] Furthermore, the ventilation slit is a longitudinal strip, with a length accounting for 70% of the height of the seedling cavity and a width of 0.6 mm. The distance between adjacent slits is three times the width of the slit, which ensures air circulation while maintaining structural strength.

[0018] Furthermore, the slow-release water-retaining coating incorporates 5% by mass of humic acid particles with a particle size between 0.1 mm and 0.3 mm, which are uniformly dispersed within the coating to slowly release nutrients and regulate the water penetration rate.

[0019] Furthermore, the bottom tray has a circular through hole with a diameter of 10 mm in the center for inserting an auxiliary top rod to assist the root ball in detaching under special soil conditions; the edge of the through hole is covered with a plastic ring to prevent sharp edges from damaging the root system.

[0020] Furthermore, the outer side of the bottom annular flange of the support base is provided with anti-slip teeth, with a tooth height of 0.4 mm and a tooth pitch of 1.8 mm, which increases frictional resistance when placed on the ground and prevents slippage.

[0021] Furthermore, the hinge shaft adopts a double bearing structure, with the outer ring of the bearing fixed to the arc-shaped movable plate and the inner ring connected to the main pot body, ensuring smooth rotation and wear resistance; the bearing gap is filled with grease to adapt to the dusty environment in the field.

[0022] Furthermore, the damping washer of the carrying assembly is made of nitrile rubber with a Shore hardness of 70A, providing moderate resistance so that the folding lifting rod can stop at any angle, facilitating one-handed operation.

[0023] This utility model provides a portable transplanting pot for chili seedling cultivation, which has the following beneficial effects:

[0024] This root-protecting pot features a side-opening structure, allowing the curved movable plate to flip outwards during transplanting, directly exposing the sides of the root ball. Demolding is achieved without additional tools, minimizing manual intervention on the root system. The elastic reset plate in the bottom release mechanism works in conjunction with the lifting claws, automatically unlocking when the bottom tray is lightly pressed, ensuring a smooth and stable descent of the root ball and avoiding structural damage or root tearing caused by traditional knocking methods. The carrying component combines a folding lifting rod with a damping pivot, saving space when folded and providing an ergonomic grip angle when unfolded, significantly improving field transport efficiency. A breathable slit and a slow-release water-retaining coating work synergistically to maintain suitable humidity and gas exchange during transport, ensuring seedling survival. All components utilize physical connections and mechanical structures to achieve their functions, requiring no external energy source or complex control devices, resulting in low manufacturing costs, easy maintenance, and suitability for large-scale agricultural promotion.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figures 1 to 3 This utility model provides a portable transplanting root protection pot for chili seedling cultivation. The overall structure consists of four main parts: the main pot body 1, the side opening and closing structure, the bottom detachment mechanism, and the carrying component. The parts are physically coordinated and mechanically connected to form a complete functional system, which is suitable for field transportation, centralized seedling cultivation, and non-destructive transplanting operations.

[0032] The main pot 1 is cylindrical in shape and divided into upper and lower sections along its height. The upper section is the seedling cavity 2, and the lower section is the supporting base 3. A longitudinally spaced ventilation slit 4 is formed on the outer wall of the seedling cavity 2. The slit length accounts for 70% of the total height of the seedling cavity 2, the width is 0.6 mm, and the spacing between adjacent slits is 1.8 mm, maintaining structural strength while ensuring air circulation. The inner wall of the seedling cavity 2 is fully covered with a slow-release water-retaining coating 6. This coating is between 0.5 mm and 1.2 mm thick and is made of a mixture of natural cellulose and bentonite, uniformly incorporating 5% humic acid particles by mass, with particle sizes ranging from 0.1 mm to 0.3 mm, to slowly release nutrients and regulate the water penetration rate. The bottom of the support base 3 is provided with an annular flange 5, and the inner side of the flange forms a stepped snap-fit ​​surface for mating with the edge of the bottom tray 11; the outer side of the annular flange 5 is pressed with anti-slip teeth, with a tooth height of 0.4 mm and a tooth spacing of 1.8 mm, which increases frictional resistance when placed on the field ridge or seedbed to prevent accidental slippage.

[0033] A lateral opening and closing structure is arranged on the outside of the seedling cavity 2 of the main pot body 1, including a pair of arc-shaped movable plates 7, a hinge shaft 8, and a locking protrusion 9. The arc-shaped movable plates 7 extend along the height direction of the main pot body 1, with their inner surfaces fitting against the outer wall of the seedling cavity 2, and their outer surfaces pressed with anti-slip textures 10 for easy manual gripping and force application. The hinge shaft 8 is fixed at the connection between the top of the arc-shaped movable plates 7 and the top of the supporting base 3, and adopts a double bearing structure. The outer ring of the bearing is riveted to the arc-shaped movable plates 7, and the inner ring is welded to the main pot body 1. The bearing gap is filled with grease to adapt to the dusty environment of the field and ensure smooth rotation and wear resistance. The locking protrusion 9 is located in the middle of the inner side of the arc-shaped movable plates 7, with a trapezoidal cross-section, wider at the top and narrower at the bottom. It forms a wedge-shaped fit with the groove at the corresponding position on the outer wall of the main pot body 1, and self-locks by gravity when closed. The top of the locking protrusion 9 has a finger groove 25 for inserting a finger to apply lateral pushing force to release the lock. A flexible sealing strip 26, made of silicone, is bonded to the inner side of the arc-shaped movable plate 7 along its length. The strip has a semi-circular cross-section and its height is consistent with the wall thickness of the main bowl 1. In the closed state, it fills the gaps and reduces moisture evaporation loss.

[0034] The bottom disengagement mechanism includes a bottom tray 11, a lifting claw 12, and an elastic reset plate 13. The bottom tray 11 is a circular flat plate with a diameter slightly smaller than the inner diameter of the support base 3. Four notches 14 are evenly distributed along its edge, and the shape of the notches matches the end of the lifting claw 12. The lifting claw 12 is an L-shaped metal plate, one end of which is welded and fixed to the bottom of the inner wall of the support base 3, and the other end extends upward and inserts into the notch 14 of the bottom tray 11. The top of the claw is provided with a sloping guide structure 15 with an inclination angle of fifteen degrees. The material is stainless steel and has been passivated, making it corrosion-resistant and wear-resistant. When the bottom tray 11 is pressed downward from the outside, the sloping guide structure 15 contacts the edge of the notch 14, generating a downward component force, which causes the claw to disengage from the limit position. The elastic reset plate 13 is an arc-shaped spring steel sheet, with both ends riveted to the inner wall of the support base 3 and the bottom surface of the bottom tray 11, respectively. Its initial bending angle is 30 degrees, providing stable upward support under normal conditions, ensuring contact between the bottom tray 11 and the stepped surface of the support base 3. A stress relief hole 16 with a diameter of 3.5 mm is opened in the center of the elastic reset plate 13 to reduce the risk of metal fatigue caused by repeated bending. Radial drainage grooves 27 are pressed onto the upper surface of the bottom tray 11, with a depth of 0.8 mm and a width of 1.5 mm, extending from the center to the edge to guide excess water out along the sidewalls and prevent water accumulation at the roots. A circular through hole 28 with a diameter of 10 mm is provided in the center of the bottom tray 11, with the edge covered by a plastic ring, for inserting an auxiliary push rod to assist in the removal of the root ball, improving the demolding success rate under special heavy clay soil conditions.

[0035] The carrying assembly includes a folding lifting rod 17, a pivot seat 18, and a limiting stop 19. The folding lifting rod 17 consists of two straight rods connected by a central pivot. Damping washers 20 made of nitrile rubber with a Shore A hardness of 70A are fitted on both sides of the pivot, providing moderate rotational resistance so that the folding lifting rod 17 can stop at any unfolded angle for easy one-handed operation. The ends of the two straight rods of the folding lifting rod 17 are equipped with spherical grip heads 21, covered with rubber sleeves 22. The surface of the rubber sleeves 22 is pressed with diamond-shaped anti-slip texture to improve grip comfort and stability. The straight rods have a hollow internal structure with a wall thickness of 1.2 mm to reduce the overall weight. The pivot seat 18 is a U-shaped bracket, fixed symmetrically to the outside of the main bowl body 1 support base 3, with the opening facing upwards, to accommodate the ends of the folding lifting rod 17. A reinforcing rib plate 23 is welded to the bottom of the pivot seat 18. The rib plate extends vertically, with a height one-third of the height of the main bowl body 1 and a width twice the thickness of the pivot seat 18, enhancing the structural rigidity during the lifting process. A limiting baffle 19 is welded to the inner side of the pivot seat 18 to limit the unfolding angle of the folding lifting rod 17 to 120 degrees, preventing excessive unfolding that could lead to structural failure. The outer wall of the main bowl body 1 supporting the base 3 is provided with a positioning boss 24, located below the pivot seat 18. When the folding lifting rod 17 is retracted, its lower section abuts against the positioning boss 24 to prevent free swinging that could interfere with operation or transportation.

[0036] During the seedling stage, nutrient soil is filled into the seedling cavity 2, pepper seeds are sown, and routine seedling management is completed. The breathable slits 4 and the slow-release water-retaining coating 6 work synergistically to maintain suitable humidity and gas exchange in the root zone, ensuring healthy seedling growth. During transport, the folding handle 17 is extended to 120 degrees, and the user holds the spherical grip head 21 with both hands, lifting to move the entire root-protecting pot; the damping washer 20 ensures the stability of the handle angle and prevents wobbling; the anti-slip serrations and reinforcing ribs 23 together ensure structural stability during the lifting process. During transplanting, first insert your finger into the actuating groove 25 and push the locking protrusion 9 horizontally to release the lock. Then, flip the curved movable plate 7 outward to expose the side of the root ball. Next, gently press down on the bottom tray 11. The lifting claw 12, guided by the inclined guide structure 15, disengages from the notch 14, and the elastic reset piece 13 is compressed accordingly. After the bottom tray 11 loses its support, it falls smoothly into the planting hole along with the root ball. If the soil is heavy and has great resistance, an auxiliary push rod can be inserted through the circular through hole 28 to apply additional pushing force. After transplanting, the curved movable plate 7 can be closed again, and the locking protrusion 9 is embedded in the groove to complete self-locking. The root protection pot can be recycled, cleaned, and reused.

[0037] All components are made from engineering plastics or metals that are weather-resistant and cost-effective for agricultural environments. The main bowl body 1, the curved movable plate 7, and the bottom tray 11 are made of polypropylene injection molding; the hinge shaft 8, the lifting claw 12, and the elastic reset plate 13 are made of stainless steel by stamping or machining; and the flexible sealing strip 26, the rubber sleeve 22, and the damping washer 20 are made of silicone or nitrile rubber by molding. All connections are made by riveting, welding, or interference fit, allowing for assembly and disassembly without additional fasteners or tools. The entire structure does not rely on electricity or automated control; it functions entirely through physical construction and manual operation, making it suitable for large-scale agricultural promotion and use by grassroots farmers.

[0038] Under different soil types or climatic conditions, the thickness of the slow-release water-retaining coating 6, the density of the breathable slits 4, and the depth of the radial drainage channels 27 can be adjusted to meet different water management needs. After continuous use for several seasons, if the elastic reset plate 13 becomes fatigued and loose, this component can be replaced separately, while the rest of the structure can continue to serve, extending the overall service life. The folding lifting rod 17 fits snugly against the outer wall of the main pot body 1 when folded, without adding extra volume, making it easy to stack for storage and bulk transportation. The maximum opening angle of the arc-shaped movable plate 7 after flipping is limited by the design of the hinge pivot 8, avoiding excessive opening and closing that could damage the root system or compromise the integrity of the sealing strip. The fit tolerance between the lifting claw 12 and the notch 14 is controlled within ±0.1 mm, ensuring sensitive and reliable unlocking action. The ends of the radial drainage channels 27 extend to the edge of the bottom tray 11, forming a drainage channel with the gap between the radial drainage channels and the inner wall of the main pot body 1, preventing water accumulation.

[0039] This root-protecting pot allows for standardized filling and mechanized handling in factory-scale seedling nurseries, while supporting manual operation and flexible adjustments in smallholder fields, balancing large-scale efficiency with individualized adaptation. During transplanting, the root ball integrity is higher than in traditional paper or plastic pots, significantly improving the survival rate of chili seedlings, shortening the greening period, and increasing early yield. The modular design allows for independent replacement of damaged parts, reducing maintenance costs. All exposed sharp edges are chamfered or covered, complying with agricultural machinery safety regulations.

[0040] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
