Description

Technical Field

[0001] This invention relates to the field of Camellia oleifera seedling cultivation technology, specifically to a reciprocating motion quantitative soil loading device for Camellia oleifera seedling cultivation. Background Technology

[0002] In the large-scale seedling production process of Camellia oleifera in southern China, substrate filling is the most labor-intensive basic process. At present, two types of filling equipment are commonly used in the industry. One type is a small manual soil filling funnel and a simple pot making machine, which relies on manual shoveling and single-cylinder feeding, and is only suitable for small-scale seedling cultivation by individual farmers. The other type is a general-purpose seedling substrate filling machine, which consists of a fixed material storage box, a single spiral mixing shaft, a fixed feeding port, and a single soil receiving station. It relies on a single motor to drive the spiral to transport nutrient soil, and the fixed material box directly drops the material downwards. It belongs to the general-purpose substrate filling tool in the forestry seedling field.

[0003] In traditional technology, the material box only has a mixing structure. When the nutrient soil gets wet, it is very easy for it to clump together. The soil layer can easily form an air gap in the middle of the material box. Mixing in only one direction cannot completely break up the matrix. Wet soil clumps will continue to stick to the side wall of the material box. Long-term accumulation will block the material discharge channel, requiring the machine to be stopped and manually shoveled to clean it, which greatly interrupts the production line operation. Relying solely on manual periodic tapping of the outer wall of the material box to remove the sticky soil is ineffective and labor-intensive. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the present invention aims to provide a reciprocating motion quantitative soil loading device for camellia seedling cultivation, which solves the problem that existing technologies cannot completely disperse the substrate by relying solely on unidirectional stirring, resulting in the continuous adhesion and caking of wet soil clumps on the side walls of the material box, long-term accumulation and blockage of the material discharge channel, requiring machine shutdown and manual soil removal.

[0017] 3. In this invention, by using a dual-station synchronous sliding material receiving and gravity self-starting unloading structure, the material receiving and sealing and material unloading switching are completed synchronously by a single power component.

This allows for precise control of the substrate capacity for each filling, ensuring that the soil volume in all camellia seedling bags is uniform and consistent. The unloading process is smooth and continuous, effectively improving the overall efficiency of batch seedling filling operations. Attached Figure Description

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0021] Example: Please refer to Figures 1-8 The present invention provides a technical solution: A reciprocating quantitative soil loading device for camellia seedling cultivation includes a base 1, a support column 2 fixedly connected to the top of the base 1, a workbench 3 fixedly connected to the top of the support column 2, a material box 4 fixedly connected to the top of the workbench 3, a frame 5 fixedly connected to the outside of the material box 4, a vertical shaft 6 rotatably connected to the middle of the inside of the frame 5, support rods 7 fixedly connected to the top and bottom of the vertical shaft 6, cylinders 8 fixedly connected to both ends between the two support rods 7, a collar 9 rotatably connected to the outside of the cylinder 8, and a mounting bracket fixedly connected to the outside of the collar 9. Mounting rod 10 is slidably connected to the outside of frame 5. One end of mounting rod 10 is rotatably connected to impact head 11, which is made of rubber. Mounting base 12 is fixedly connected between two support rods 7. A semi-circular frame 13 is rotatably connected to the inner wall of mounting base 12. One end of semi-circular frame 13 is fixedly connected to a rotating shaft 14, and one end of rotating shaft 14 is fixedly connected to an inclined block 15. In the early stage of operation, the staff continuously feeds the prepared and evenly proportioned camellia seedling special nutrient soil into the material box 4. The machine features centralized material storage. Base 1 serves as the main support, supported by multiple vertical pillars 2 that lift the worktable 3, providing ample operating space for the seedling bags below. Worktable 3 supports the material bin 4 and facilitates material flow. The material bin 4 is encased in a frame 5 to support the entire anti-blocking impact mechanism. A vertical shaft 6 acts as the central rotating component, synchronously driving two symmetrically arranged support rods 7 to oscillate in a circular motion. A cylinder 8 and a collar 9 form a self-adaptive, slightly deflectable hinge structure, effectively buffering vibrations generated by impacts. The outer mounting rod 10 is moved synchronously, and the rubber impact head 11 at the end of the rod continuously and periodically strikes the side wall of the material box 4. The soft impact shakes off the damp and clumps of substrate adhering to the inside of the box. The mounting seat 12 between the two sets of support rods 7 provides an arc-shaped rotation track for the semi-arc frame 13. The rotating shaft 14 receives the rotational torque output by the power component and drives the end tilting block 15 to rotate synchronously. This converts the circumferential power into the reciprocating swing power of the support rod 7, eliminating the phenomenon of nutrient soil accumulating on the wall and blocking the material discharge channel from the source.

[0022] Furthermore, in this embodiment, a first motor is fixedly connected to the outside of the frame 5. The output end of the first motor is fixedly connected to the other side of the tilting block 15. The output end of the first motor is rotatably connected to the inside of the frame 5. An extension side is fixedly connected to the end of the frame 5 near the material box 4. When the whole machine enters the filling operation stage, the first motor mounted on the outside of the frame 5 is started. The motor output shaft continuously outputs rotational power at a constant speed and directly connects to the tilting block 15 to realize torque transmission. As the tilting block 15 follows the circumferential rotation of the output shaft, it continuously pushes and pulls the rotating shaft 14, thereby driving the semi-arc frame 13 to reciprocate along the arc trajectory inside the mounting base 12. When the semi-arc frame 13 deflects, it synchronously pulls the support rods 7 on both sides of the vertical shaft 6 to complete the reciprocating swing cycle. The extension side of the frame 5 extending towards the material box 4 can limit the maximum swing stroke of the support rod 7, avoid excessive impact from the impact head 11 causing deformation and dent of the metal material box 4. At the same time, the extension side can disperse the knocking vibration, reduce the resonance noise generated during the operation of the whole machine, and stably maintain a continuous and uniform knocking effect on the box wall.

[0023] Furthermore, in this embodiment, the bottom of the material bin 4 has an open structure design, and the interior of the workbench 3 and the material bin 4 are interconnected. A connecting shaft 16 is rotatably connected to the top of the inner side of the material bin 4, and multiple rake teeth 17 are fixedly connected to the outside of the connecting shaft 16. The rake teeth 17 have a figure-eight structure design. A guide rod 18 is fixedly connected to one end of the connecting shaft 16 extending to the outside of the material bin 4. The bottom of the material bin 4 is completely open without a closed partition, and the stored nutrient soil can be transported vertically downward through the through channel inside the workbench 3 to the receiving station below without obstruction. A connecting shaft 16 is horizontally mounted on the upper part of the inner cavity. Multiple sets of figure-eight shaped rake teeth 17 are symmetrically arranged on the outside of the shaft. During the reciprocating swing, the rake teeth 17 can cover the entire storage area on the upper part of the material box 4, continuously stirring the surface layer of accumulated nutrient soil to break up the gaps and avoid the soil layer compaction forming a bridging blockage that prevents material from being discharged. The end of the connecting shaft 16 extending outward is fixed with a guide rod 18. The guide rod 18 bears the pushing and pulling force of the rear transmission component, converting the horizontal reciprocating power into the back-and-forth rotation and swing of the connecting shaft 16, continuously expanding the soil stirring coverage of the rake teeth 17.

[0024] Furthermore, in this embodiment, a synchronous shaft 19 is rotatably connected to the bottom of the inner side of the material box 4. A drive rod 20 is fixedly connected to one end of the synchronous shaft 19. A driven rod 21 is rotatably connected between the drive rod 20 and the guide rod 18. A first stirring blade 22 is fixedly connected to the outside of the synchronous shaft 19. The synchronous shaft 19 is horizontally mounted at the bottom of the inner cavity of the material box 4 as a bottom stirring bearing component. The drive rod 20 fixed at the end of the shaft moves in a circular motion in sync with the synchronous shaft 19. When the drive rod 20 rotates, it continuously pushes and pulls the driven rod 21, which is hinged in the middle. The driven rod 21 then transmits the cyclic pushing and pulling torque to the guide rod 18, so as to realize the synchronous linkage between the bottom stirring operation and the upper rake teeth 17 swinging. The first stirring blade 22, which is integrally assembled on the outside of the synchronous shaft 19, continuously rotates and stirs the bottom nutrient soil that is about to fall, breaks up small mud clumps and guides the loose soil to flow downward. The upper and lower stirring structures work in sync to ensure that the nutrient soil inside the material box 4 is not layered and compacted or has large clumps.

[0025] Furthermore, in this embodiment, an installation strip 23 is fixedly connected to the bottom left side of the material box 4. The synchronous shaft 19 extends to the left side inside the installation strip 23 and is rotatably connected to the installation strip 23. A first bevel gear 24 is rotatably connected to one side of the installation strip 23, and a sleeve 25 is rotatably connected to the right side inside the installation strip 23. The synchronous shaft 19 passes through the inside of the sleeve 25 and is rotatably connected to the sleeve 25. The long strip-shaped installation strip 23 fixed to the lower left side wall of the material box 4 serves as the bearing base for the entire reverse gear transmission mechanism. The left end of the synchronous shaft 19 extends into the inside of the installation strip 23 to complete the rotation positioning support. An assembly position is reserved on the outside of the installation strip 23 for installing the first bevel gear 24 for power input. A hollow structure sleeve 25 is coaxially mounted inside the installation strip 23. The synchronous shaft 19 passes through the central gap of the sleeve 25, and the two are independent of each other without rigid linkage. The two coaxial components rotate independently in opposite directions by relying on gear meshing. A bidirectional stirring layout is achieved in a small space, and the forward and reverse synchronous stirring action can be completed without the need to add two sets of independent drive motors.

[0026] Furthermore, in this embodiment, a second bevel gear 26 is fixedly connected to the left end of the synchronous shaft 19, and a third bevel gear 27 is fixedly connected to the left end of the sleeve 25. The first bevel gear 24 meshes with the second bevel gear 26 and the third bevel gear 27. A second motor is fixedly connected to the bottom of the outer side of the material box 4, and the output end of the second motor is fixedly connected to the first bevel gear 24. A second stirring blade 28 is fixedly connected to the outside of the sleeve 25. Both the first stirring blade 22 and the second stirring blade 28 have a spiral structure design. After starting the second motor mounted on the outer side of the bottom of the material box 4, the motor output shaft drives the first bevel gear 24 at a constant speed. As the rotation proceeds, the first bevel gear 24 simultaneously engages with the second bevel gear 26 on the left and the third bevel gear 27 on the right, causing the two driven bevel gears to rotate synchronously in completely opposite directions under the meshing force. The second bevel gear 26 drives the synchronous shaft 19 and the outer first stirring blade 22 to push the material in a forward spiral motion, while the third bevel gear 27 drives the sleeve 25 and the outer second stirring blade 28 to spirally comb the soil layer in a reverse spiral motion. The two sets of spiral blades cross and stir the nutrient soil in both directions, which can fully tear apart the moist and clumped substrate and increase the air circulation inside the soil, greatly improving the overall flowability of the nutrient soil and fundamentally reducing the probability of soil sticking to the pipe wall and clogging the discharge port.

[0027] Furthermore, in this embodiment, an extension plate is fixedly connected to the outside of the base 1, and a rectangular plate 29 is fixedly connected to the middle of the top of the base 1. Two receiving frames 30 are slidably connected to the top of the rectangular plate 29, and an arched block 31 is fixedly connected between the two receiving frames 30. An electric telescopic rod is fixedly connected to the extension plate, and the output end of the electric telescopic rod is fixedly connected to the arched block 31. An integrally formed extension plate extends outward from the side of the base 1, and installation points are reserved on the surface of the extension plate for horizontally fixing the electric telescopic rod. A rectangular plate 29 is horizontally laid in the middle of the base 1 as a quantitative receiving plate. The mechanism has two sets of identical receiving frames 30 arranged parallel above the rectangular plate 29 on the sliding guide rail. The two receiving frames 30 are rigidly connected by an arched block 31 to form a synchronous sliding assembly. When the electric telescopic rod extends or retracts, it directly pushes and pulls the arched block 31, causing the two sets of receiving frames 30 to move horizontally back and forth along the rectangular plate 29 synchronously. One set of receiving frames 30 moves to the bottom of the outlet of the workbench 3 to receive a quantitative amount of nutrient soil, while the other set moves synchronously to the unloading station to complete the filling of seedling bags with soil, realizing uninterrupted continuous cycle operation and greatly improving the efficiency of batch filling of soil for camellia seedlings.

[0028] Furthermore, in this embodiment, the top of the receiving frame 30 is interconnected with the interior of the workbench 3. The bottom of the receiving frame 30 is fixedly connected to a mounting ear, and a bent rod 32 is rotatably connected inside the mounting ear. The other end of the bent rod 32 is fixedly connected to a bottom sealing plate 33. Mounting ears are symmetrically welded to both sides of the bottom of each receiving frame 30. A pivot hole is opened inside the mounting ear to hinge the bent rod 32. The lower end of the bent rod 32 is horizontally fixed to the bottom sealing plate 33, forming an automatic opening and closing bottom door structure. When the receiving frame 30 is in the receiving position below the workbench 3, the rectangular plate 29 supports the bottom sealing plate 33, keeping it horizontally closed and completely receiving the quantitative nutrient soil falling from the material box 4. When the receiving frame 30 slides to the unloading area without bottom plate support, the weight of the nutrient soil inside the frame presses down on the bottom sealing plate 33, causing the bent rod 32 to automatically rotate downwards around the mounting ear, achieving an automatic unloading structure without additional electrical control, simplifying the overall electrical control logic of the machine. Furthermore, in this embodiment, both ends of the top of the rectangular plate 29 are fixedly connected to limit plates 34, and the receiving frame 30 is slidably connected between the two limit plates 34. The left and right ends of the rectangular plate 29 are vertically fixed to the limit plates 34, and the two limit plates 34 are parallel to each other to form a sliding constraint track. The two sets of receiving frames 30 are stuck between the two limit plates 34 and slide laterally throughout the process, which can prevent the receiving frames 30 from shifting left and right, getting stuck and derailing during the push and pull of the electric telescopic rod. When one set of receiving frames 30 slides to the unloading position, the upper surface of the other set of receiving frames 30 is close to the bottom discharge port of the workbench 3, completely blocking the material flow channel, accurately stopping the continuous falling of nutrient soil, strictly controlling the total amount of soil falling into the seedling bag at one time, and ensuring that the weight of the camellia seedling substrate in each bag is uniform.

[0029] Furthermore, in this embodiment, two square grooves 35 are provided inside the base 1. The square grooves 35 are adapted to the receiving frame 30, and the width inside the square grooves 35 is greater than the width of the bottom plate 33. Two square grooves 35 are provided in the middle of the base 1 corresponding to the feeding stroke of the two sets of receiving frames 30. The lateral dimension of the square grooves 35 matches the outer contour of the receiving frame 30. The reserved width inside the square grooves 35 is greater than the maximum width of the bottom plate 33 after it is unfolded. When the receiving frame 30 slides to the top of the square grooves 35, the bottom completely loses the support of the rectangular plate 29. The bottom plate 33 has sufficient space to flip downwards. The quantitative nutrient soil inside the frame can fall vertically into the camellia seedling bag placed below without obstruction. After feeding is completed, the electric telescopic rod pulls the receiving frame 30 back to reset, and the bottom plate 33 is lifted and closed again by the rectangular plate 29, and the feeding cycle begins again. In this embodiment, the specific implementation scenario is as follows: Workers first continuously add the prepared, balanced organic matter and loose medium-specific nutrient soil for camellia seedling cultivation into the material box 4 to complete centralized material storage. The base 1 serves as the integrated support base for the entire machine, relying on multiple vertical support columns 2 to lift the workbench 3 upwards. Sufficient operating space is reserved below the workbench 3 for placing seedling bags. The vertically connected cavity of the workbench 3 opens up the material flow channel between the material box 4 and the receiving mechanism below. The outer side of the material box 4 is entirely covered by a frame 5 to support the entire anti-blocking and anti-impact assembly of the box wall. A vertical axis 6 is vertically arranged at the center of the frame 5 as the rotation center for reciprocating swing. Two sets of support rods 7 are simultaneously assembled at the upper and lower ends of the vertical axis 6. The two ends of the support rods 7 form a slightly adaptive deflection through cylinders 8 and collars 9. The frame features a hinged structure with a mounting rod 10 fixed to the outside of the collar 9. A rubber impact head 11 is rotatably mounted at the end of the mounting rod 10. A mounting base 12 is positioned between the two sets of support rods 7. The inner cavity of the mounting base 12 allows the semi-circular frame 13 to rotate along an arc-shaped trajectory. One end of the semi-circular frame 13 is connected to a rotating shaft 14, with an inclined block 15 fixed at the end of the rotating shaft 14. During operation, the first motor mounted on the outside of the frame 5 is activated. The motor's output shaft, connected to the inclined block 15, outputs a uniform rotational torque, continuously pushing and pulling the rotating shaft 14 to cause the semi-circular frame 13 to reciprocate. This, in turn, pulls the vertical shaft 6 and the two side support rods 7 to swing cyclically, causing the mounting rod 10 and the impact head 11 to periodically strike the outer wall of the material box 4. The flexible rubber impact head 11 can dislodge clumps formed by the adhesion of damp nutrient soil. The frame 5 faces the material box 4. The extended side constrains the maximum swing amplitude of the support rod 7, avoiding excessive impact force that could deform the box and reducing overall resonance noise. The bottom of the material box 4 adopts a completely open structure. A connecting shaft 16 is horizontally mounted on the upper part of the inner cavity. Multiple sets of figure-eight rake teeth 17 are fixed to the outside of the connecting shaft 16. A guide rod 18 is installed at the end of the shaft extending outward. A synchronous shaft 19 is synchronously arranged at the bottom of the inner cavity of the material box 4. A drive rod 20 is fixed to the end of the synchronous shaft 19. A driven rod 21 is hinged between the drive rod 20 and the guide rod 18. A spiral structure first stirring blade 22 is integrally assembled on the outer wall of the synchronous shaft 19. A long strip mounting bar 23 is fixed to the lower left side wall of the material box 4. A first bevel gear 24 is rotatably mounted on the outside of the mounting bar 23. A hollow sleeve 25 is coaxially inserted inside. The synchronous shaft 19 is driven by the sleeve. The central gap of sleeve 25 allows independent passage without interference. A second bevel gear 26 is fixed to the left end of synchronous shaft 19, and a third bevel gear 27 is fixed to the left end of sleeve 25. A second motor is installed on the outer side of the bottom of the material box 4. The output shaft of the second motor is rigidly connected to the first bevel gear 24. A spiral structure second stirring blade 28 is fixed to the outer wall of sleeve 25. After the second motor is started, the first bevel gear 24 synchronously meshes, driving the second bevel gear 26 and the third bevel gear 27 to rotate in opposite directions. This drives synchronous shaft 19 (with the first stirring blade 22) and sleeve 25 (with the second stirring blade 28) to respectively perform bidirectional spiral stirring of the bottom nutrient soil, fully breaking up the clumps of substrate and improving soil flowability. During the rotation of synchronous shaft 19, the drive rod 20 performs circular motion, continuously pushing and pulling the guide rod 18 via driven rod 21.The linkage shaft 16 and the figure-eight rake teeth 17 sweep back and forth on the upper layer of the material box 4, breaking up the bridging gaps formed by the soil layer, allowing the loose and uniform nutrient soil to continuously pass through the workbench 3 and be conveyed downwards. The base 1 extends outwards from the side with an integrally formed extension plate, and the extension plate is horizontally fixed with an electric telescopic rod. A rectangular plate 29 is laid flat in the middle of the base 1 as a sliding guide rail. The two ends of the rectangular plate 29 are vertically fixed with limit plates 34. Two sets of identical material receiving frames 30 are slidably assembled between the two limit plates 34. The two material receiving frames 30 are rigidly connected by an arched block 31 to form a synchronous sliding assembly. When the electric telescopic rod extends and retracts, it pushes and pulls the arched block 31, causing the two sets of material receiving frames 30 to move synchronously horizontally between the limit plates 34. When one set of material receiving frames 30 moves to the bottom of the workbench 3 to receive the falling nutrient soil, the top of the other set of material receiving frames 30 is attached to the bottom surface of the workbench 3 to block the channel, accurately controlling the single-time soil loading capacity. The bottom of each material receiving frame 30 Symmetrical welding installation ears are used, with a hinged bending rod 32 inside the installation ear. The lower end of the bending rod 32 is fixed to the bottom plate 33. When the receiving frame 30 is in the receiving position, the rectangular plate 29 supports the bottom plate 33 to keep it closed and receive the soil. Two square grooves 35 are opened inside the base 1 corresponding to the movement trajectory of the two sets of receiving frames 30. The width of the square grooves 35 is larger than the size of the bottom plate 33 when it is fully unfolded. When the electric telescopic rod drives the receiving frame 30 filled with nutrient soil to slide directly above the square groove 35, the bottom plate 33 loses the support of the rectangular plate 29. The weight of the nutrient soil in the frame presses down on the bending rod 32, causing the bottom plate 33 to automatically flip downwards. The quantitative nutrient soil falls vertically into the pre-placed camellia seedling bags without obstruction, completing the soil filling. After the material is discharged, the electric telescopic rod pulls the receiving frame 30 in the opposite direction to reset it. The bottom plate 33 is then supported and closed again by the rectangular plate 29. The whole machine continuously cycles to complete the quantitative soil filling operation for continuous batch camellia seedling cultivation.
