Description

Technical Field

[0001] This invention relates to the field of agricultural planting technology. Specifically, it is a jujube seedling cultivation device based on corn cobs. Background Technology

[0002] Grafting of jujube trees results in a more developed root system and stronger adaptability compared to cutting propagation, making it the basic form of jujube tree propagation currently. Field propagation is the main method, but seedlings taken from field nurseries usually cannot be grown with soil balls, resulting in a low survival rate in afforestation. Container propagation requires purchasing expensive substrates and then bagging the seedlings according to strict proportions, which is labor-intensive and costly.

[0003] Currently, jujube seedling cultivation mainly involves sowing jujube kernels to cultivate rootstocks before grafting. The price of jujube kernels has remained high in recent years, reaching 800-1000 yuan / kg. The breakage rate during the pitting and seed production process is close to 10%, highlighting the urgent need for new approaches to improve economic efficiency. Corn cobs are readily available and possess inherent looseness and water / fertilizer retention properties. Their rational processing and creative utilization represent a simple, low-cost, and practical seedling cultivation method that ensures high survival rates in afforestation.

[0004] This invention utilizes corn cobs, which are easy to obtain and inexpensive, to replace the more expensive container seedling substrate after segmentation. It also uses treated perforated jujube pits instead of jujube kernels to protect the expensive jujube seeds from damage. The invention also features a well-designed mechanical planting device that reduces costs and increases efficiency. Summary of the Invention

[0005] Therefore, the technical problem to be solved by the present invention is to provide a corn cob-based jujube seedling cultivation device for mass cultivation of jujube trees using corn cob as a culture medium.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0007] A jujube seedling cultivation device based on corn cobs includes a storage cylinder, which consists of a cylindrical wall and a bottom plate. The outer side of the cylinder wall is rotatably connected to a support frame with the rotation axis arranged obliquely. Multiple temporary storage slots for storing jujube pits are formed on the side of the bottom plate facing the cylinder wall. The middle of each storage slot is semi-cylindrical, while both ends are conical. The central axis of the storage slot intersects and is perpendicular to the axis of the storage cylinder. The storage slots are evenly spaced along the axis of the storage cylinder. Adsorption vents and material outlets are respectively provided on the outer side of the bottom plate at positions corresponding to the ends of the storage slots. The end of the storage slot connected to the material outlet corresponds to the rotation direction of the storage cylinder. A fan-shaped suction plate is provided on the outer side of the bottom plate corresponding to each adsorption vent. A fan-shaped discharge plate is provided at the corresponding position of the outlet. The fan-shaped discharge plate cooperates with the fan-shaped suction plate and covers the annular area of ​​the corresponding temporary storage tank. A discharge pipe that cooperates with the material discharge port is connected to the fan-shaped discharge plate. The lower end of the discharge pipe is connected to a planting mechanism for planting jujube pits. The planting mechanism includes a vertically arranged hollow planting rod. The planting rod is driven by a telescopic rod and performs vertical reciprocating motion. The upper end of the telescopic rod is fixedly connected to the support frame and the lower end is fixedly connected to the planting rod. A feed port connected to the protruding end of the discharge pipe is provided on the side of the planting rod. A pressing rod is vertically slidably connected inside the planting rod. The upper end of the pressing rod is connected to the upper end of the planting rod by a return spring. A limiting member is provided on the outside of the pressing rod to limit the pressing rod.

[0008] The technical solution of the present invention achieves the following beneficial technical effects:

[0009] This method is suitable for large-scale industrial seedling production. Using corn cobs as the culture medium during seedling cultivation not only helps maintain good temperature and humidity during seed germination, but also allows the corn cobs to function as fertilizer. After germination, the corn cobs are planted along with the seeds, providing nutrients without damaging the seed's fragile root system during transplanting. The roots can directly anchor themselves in the corn cob material. The nutrients from the corn cob are not absorbed all at once after transplanting, maintaining a sustained nutrient supply. During this process, the corn cob provides good support for the seedlings, resulting in more stable root systems compared to traditional transplanting. The loose, breathable structure of the corn cob also ensures good aeration for the roots, making the seedlings less susceptible to lodging in wind. Furthermore, corn cobs are readily available and inexpensive, providing fertilizer to the root system during the early growth stages, thereby improving seedling survival rates.

[0026] This embodiment will be described in detail with reference to the accompanying drawings.

[0027] In this embodiment, the seeds to be used for seedling cultivation are first screened. The seeds selected for seedling cultivation are plump and of good quality jujube seeds. Before sowing, the seeds are soaked and germinated. At the same time, the corn cobs to be used are pre-treated. The two ends of the corn cobs are removed and the middle section of the same length is made as the seedling substrate. The corn cobs need to be sterilized before use. Then, they are transported by conveyor belt and wait to be planted with seeds. During the transportation of the corn cobs by the conveyor belt, the corn cobs are kept vertical and their posture is stabilized by the conveyor belt to avoid shaking.

[0028] In the process of planting seeds into corn cobs, the seeds to be planted are first placed into storage cylinder 1. Storage cylinder 1 is a cylindrical structure with one end open. The middle part of storage cylinder 1 is a cylindrical wall 2, and the lower end is closed by a circular bottom plate 3. A conical structure is used as a baffle at the upper end of the cylindrical wall 2. Because the cylindrical wall 2 needs to be kept in an inclined position during use, the conical structure at the upper opening can prevent the seeds inside from being discharged outwards, while also accommodating more seeds. The conical structure is a structure that is smaller at the top and larger at the bottom, with the upper end open and the lower end connected to the cylindrical wall 2. A ring-shaped drive gear ring is provided on the outer side of the cylindrical wall 2. The outer side of the cylindrical wall 2 is rotatably connected to a support frame. The drive gear ring is driven by a drive motor fixedly connected to the support frame, so that the cylindrical wall 2 rotates at a uniform speed on the support frame.

[0029] On one side of the base plate 3 near the cylindrical wall 2, there are multiple annularly arranged transport components for transporting seeds. Each transport component includes multiple temporary storage slots 4 for temporarily storing jujube pits. The middle of the temporary storage slot 4 is a semi-cylindrical structure, and the two ends of the semi-cylindrical structure are conical structures with the tips pointing outwards. This allows the temporary storage slot 4 to better adapt to the structure of the jujube pit, thus better matching the structure of the jujube pit while accommodating it. The diameter of the cylindrical structure in the temporary storage slot 4 is between 1.2 and 1.5 times the diameter of the jujube pit, so that only one jujube pit can be transported at a time while accommodating and transporting the jujube pit. The storage cylinder 1 is inclined, with an inclination angle ranging from 20 to 45 degrees. Each temporary storage slot 4 is connected to an adsorption vent 5 for adsorbing jujube pits. By drawing air from the adsorption vent 5 on the outside, the position of the jujube pits entering the temporary storage slot 4 is fixed, so that the base plate 3 carries only one jujube pit as it rotates with the cylinder wall. Excess jujube pits fall back into the cylindrical wall 2 under the action of gravity.

[0030] The axis of the semi-cylindrical structure in the middle of the temporary storage tank 4 is intersected and perpendicular to the axis of the cylindrical wall 2. The ends of the temporary storage tank 4 where the cylindrical structures and conical mechanisms meet are respectively provided with an adsorption vent 5 and a material outlet 6 away from the cylindrical wall 2. The adsorption vent 5 and the material outlet 6 are respectively located at one end of the temporary storage tank 4. The material outlet 6 is located at one end of the temporary storage tank 4 in the direction of movement, and the outer side of the temporary storage tank 4 is provided with an arc-shaped guide plate. The adsorption vent 5 is located at the opposite end of the temporary storage tank 4 in the direction of movement. This ensures that when the date pit is in the temporary storage tank 4, one end of the date pit is located in the temporary storage tank 4 by the adsorption force generated by the adsorption vent 5. Then, as the temporary storage tank 4 moves, it will not fall off even when it moves to the upper end of the inclined surface of the bottom plate 3.

[0031] Multiple annularly arranged sealing rings 30 are provided on the outer surface of the base plate 3. The sealing rings 30 are located outside the adsorption vent 5 and the material outlet 6, respectively. A fan-shaped suction plate 7 is rotatably connected inside the sealing ring 30. The fan-shaped suction plate 7 and the sealing ring 30 are slidably engaged. The outer side of the fan-shaped suction plate 7 is fixedly connected to the support frame, so that the position of the fan-shaped suction plate 7 remains unchanged. An air pump is connected to the outer side of the fan-shaped suction plate 7, so that the fan-shaped suction plate 7 always generates suction force on the adsorption vent 5 within the coverage area, thereby preventing the date pits from falling off during movement.

[0032] The fan-shaped suction plate 7 has a fan-shaped structure with a coverage angle of 270 degrees. It covers the upper and lower ends of the obliquely arranged base plate 3 and the side that the temporary storage tank 4 passes through as it moves from top to bottom. The overall coverage angle is 270 degrees, meaning that suction is generated whenever the temporary storage tank 4 passes within the coverage area of ​​the fan-shaped suction plate 7. This suction force is used to adsorb the jujube pits located near the jujube pits within the temporary storage tank 4. Because the temporary storage tank 4's structure corresponds to the jujube pit, it will adsorb one end of the jujube pit during the adsorption process, while the main body of the jujube pit will... Located within the temporary storage tank 4, the outer edge of the temporary storage tank 4 guides the middle part of the jujube pit into the temporary storage tank 4. The jujube pit will also adjust its position when it comes into contact with other jujube pits during the movement. Only when the jujube pit is adjusted so that one end is adsorbed and the middle part is located in the temporary storage tank 4 can most of the volume of the jujube pit be hidden in the temporary storage tank 4. In this way, when other jujube pits come into contact with the adsorbed jujube pit, they will not push the adsorbed jujube pit. At this time, the positioning and attitude adjustment of the jujube pit during adsorption are completed, which facilitates the subsequent output of the jujube pit.

[0033] The fan-shaped discharge plate 8 corresponds to the notch of the fan-shaped suction plate 7. When the temporary storage tank 4 on the base plate 3 carries the jujube pit to the area of ​​the fan-shaped suction plate 7, it will pass through the area of ​​the fan-shaped discharge plate 8. The area of ​​the fan-shaped discharge plate 8 has no adsorption force on the jujube pit. At the same time, when the temporary storage tank 4 moves to the area of ​​the fan-shaped discharge plate 8, the material outlet 6 in the temporary storage tank 4 will be located at the downward angle. Before detaching from adsorption, the jujube pit is located at the upward angle in the temporary storage tank 4. After losing the adsorption force, the jujube pit will move towards the material outlet 6 under the action of gravity. The material outlet 6 is connected to the outside of the discharge pipe 9. When the temporary storage tank 4 moves to the area of ​​the fan-shaped discharge plate 8, the material outlet 6 is arranged vertically, and the discharge pipe 9 is arranged vertically and matches the position of the material outlet 6. At this time, the adsorption of the jujube pit is released, and the jujube pit will fall into the discharge pipe 9 under the action of gravity and be discharged. Then, it will be planted by the planting mechanism.

[0034] On the side of the base plate 3 facing the cylindrical wall 2, there is a protective plate with an arc-shaped structure that protrudes outward at the position corresponding to each material outlet 6. This allows the protective plate to guide the material during the rotation of the base plate 3, preventing the date pit from entering the material outlet 6.

[0035] There are multiple outlet tubes 9, corresponding to the number of annular transport components on the base plate 3. Each outlet tube 9 corresponds to one annular transport component, ensuring that the jujube pits output by each transport component can be planted. The planting mechanism includes a vertically arranged, hollow planting rod 10. A vertically arranged telescopic rod is provided on the outside of the planting rod 10. The lower end of the telescopic rod is fixedly connected to the support frame, and the upper end of the telescopic rod is fixedly connected to the planting rod 10, allowing the planting rod 10 to perform vertical reciprocating motion under the action of the telescopic rod. The telescopic rod can be driven by hydraulic, pneumatic, or electric means, as long as the planting rod 10 can achieve reciprocating motion in the up and down directions. The planting rod 10 has a feed inlet 11 on its side, and the extended end of the outlet tube 9 corresponds to the feed inlet 11, so that the jujube pits exported from the outlet tube 9 will enter the planting rod 10 through the feed inlet 11. A pressing rod 1 is vertically slidably connected to the upper end of the planting rod 10. 2. The upper end of the planting rod 10 is connected to the upper end of the pressing rod 12 by a return spring 13. The lower end of the pressing rod 12 extends into the planting rod 10. At the same time, the upper end of the planting rod 10 has a limiting frame 19 extending upward to limit the upward movement distance of the upper end of the pressing rod 12. In the initial state, the feed inlet 11 on the side of the planting rod 10 is engaged with the outlet of the discharge pipe 9. At this time, the pressing rod 12 extends upward under the action of the return spring 13 to contact the limiting frame 19. The lower end of the pressing rod 12 extends into the inside of the planting rod 10 and is located above the feed inlet 11, so that the pressing rod 12 will not block the date pit from entering the planting rod 10. The lower end of the planting rod 10 is rotatably connected to a sealing cover 22. The sealing cover 22 prevents the residue in the corn cob from entering the planting rod 10 when the planting rod 10 is pressed down. A limiting plate for engaging the pressing rod 12 is rotatably connected to the support frame on the outside of the planting rod 10.

[0036] Due to the inherent structure of the corn cob, its central part is relatively soft and located in the middle. Therefore, during the planting process, the seed is planted in the middle of the corn cob. The diameters of both the planting rod 10 and the sealing cap 22 are smaller than the soft cylindrical structure of the corn cob, making it easy to plant the seed. The sealing cap 22 is rotatably connected to the lower end of the planting rod 10, and the outer edge of the sealing cap 22 covers the outer edge of the lower end face of the planting rod 10. This allows the sealing cap 22 to contact the softer part of the corn cob first when the planting rod 10 is pressed down, preventing corn cob residue from entering the hollow part of the planting rod 10. One end of the upper surface of the sealing cover 22 is rotatably connected to the lower surface of the planting rod 10. A vertically arranged connecting groove is provided on the side of the planting rod 10 corresponding to the rotatable connection part of the sealing cover 22. An elastic rope 24 is threaded through the connecting groove 23. The lower end of the elastic rope 24 is fixedly connected to the side of the upper surface of the sealing cover 22 facing the axis of the planting rod 10. The other end of the elastic rope 24 passes upward through the connecting groove 23 and is fixedly connected to the support frame, so that the elastic rope 24 always tends to close the sealing cover 22 under the action of elasticity. In this way, no matter what position the planting rod 10 is in, the elastic rope 24 always has a closing driving force on the sealing cover 22.

[0037] The lower end of the limiting member 14 is rotatably connected to the support frame on the outside of the planting rod 10. A limiting block 15 is provided on the support frame near the planting rod 10 to limit the movement angle of the limiting member 14. A pressing spring 16 is provided on the support frame away from the limiting member 14 to press the limiting member 14. Through the combined action of the pressing spring 16 and the limiting block 15, the limiting member 14 remains vertical and can move its upper end away from the planting rod 10 under external force. The limiting member 14 has an n-shaped structure, and a first guide block 17 is fixedly connected to its upper end. The upper end of the first guide block 17... The first guide block 17 extends diagonally downwards towards the planting rod 10. When the limiting member 14 is vertical, the lower end face of the first guide block 17 is horizontal. A second guide block 18 is fixedly connected below the first guide block 17. The lower end face of the second guide block 18 extends diagonally upwards towards the planting rod 10. A gap exists between the first guide block 17 and the second guide block 18. A first mating block 20 that mates with the first guide block 17 is fixedly connected to the upper end of the pressing rod 12, while a second mating block 21 that mates with the second guide block 18 is fixedly connected to the upper end of the planting rod 10. As the pressing rod 12 moves downwards with the planting rod 10, it reaches the planting rod 10... When the planting rod is set to the desired position, the first mating block 20 will move past the first guide block 17 in the limiting plate. Then, the limiting plate will reset under the action of the pressing spring 16. At this time, the pressing rod 12 will not move upward due to the obstruction of the first guide block 17. However, when the planting rod 10 resets, it will move upward. At this time, the pressing rod 12 will not move because its upward movement is blocked. The seed inside the planting rod 10 will remain in its original position due to the obstruction at the lower end of the pressing rod 12, while the closing cover 22 at the lower end of the planting rod 10 will be forced open, leaving the seed in the corn cob. During the upward movement of the planting rod 10, the planting rod... The return spring 13 between the upper end of the planting rod 10 and the pressing rod 12 is compressed and stores force until the second mating block 21 at the upper end of the planting rod 10 moves to contact the second guide block 18. The second mating block 21 pushes the second guide block 18, causing the upper end of the limiting member 14 to move away from the planting rod 10. After the upper end of the limiting member 14 moves away from the planting rod 10, the first guide block 17 loses its limiting effect on the first mating block 20. The pressing rod 12 moves upward and resets under the action of the return spring 13, thus completing one planting action, and then waits for the next planting action.

[0038] A sealing plate 25 extending upward is provided on the upper end face of the sealing cover 22 and on the outer side of the rotating connection part. A sealing groove 26 for accommodating the sealing plate 25 is provided on the lower end face of the planting rod 10 at the position corresponding to the sealing plate 25. In this way, when the sealing cover 22 rotates, the sealing plate 25 will be hidden in the sealing groove 26. When the sealing cover 22 is not moving, the sealing plate 25 prevents residue from entering the rotating connection part, thus avoiding blockage of the rotating connection part.

[0039] There are two planting methods for the planting rod 10. The first method involves the planting rod 10 performing periodic vertical reciprocating motion and planting according to the rotation speed of the storage cylinder 1 and the corresponding number of temporary storage slots 4. Each time the planting rod 10 moves downward, a new corn cob is moved to the corresponding position of the planting rod 10 via a conveyor belt. This method uses a feedback-free movement, which is convenient to operate but has the disadvantage of not having feedback. If no seeds are adsorbed and transported in the temporary storage slots 4, the planting operation will continue, which may result in no planting. The second method involves setting a touch sensor on the upper surface of the closed cover 22 at the position corresponding to the planting rod 10. After the seeds enter the planting rod 10, they will fall onto the upper end of the closed cover 22. At this time, the touch sensor will detect the seeds falling and then move the planting rod 10 downward to plant. This method can prevent the planting from being empty. The disadvantage is that the electronic control is prone to damage. The appropriate planting method should be adopted according to the usage requirements.

[0040] Regardless of the planting method, the conveyor belt transports the corn cobs. The corn cobs must be trimmed, retaining only the middle end, and all corn cobs must be the same height. During the transport of the corn cobs by the conveyor belt, they must be clamped when they reach below the planting rod 10 to prevent the planting rod 10 from moving the corn cobs upwards simultaneously. A limiting plate can be installed on the outside of the conveyor belt to maintain the clamping action of the conveyor belt on the corn cobs by pressing the limiting plate, thus preventing the corn cobs from moving. Each conveyor belt moves intermittently, and the distance of each movement is the spacing between the clamped corn cobs. At the same time, the transport speed of each conveyor belt corresponds to the planting speed of the planting rod 10, and the planting speed of the planting rod 10 corresponds to the number of corresponding temporary storage tanks 4.

[0041] When using corn cobs, using only one end or just the bottom section is wasteful. Furthermore, manual cutting leads to high labor costs and waste of raw materials. Therefore, a corn cob is cut into two equal sections. Two parallel conveyor belts 28 clamp the top and bottom ends of the corn cob during transport, ensuring the bottom ends are on the same plane. After cutting, the corn cob retains two sections: one at the height of the cutting belt 31 between the bottom end and the two conveyor belts 28, and the other at the height between the two cutting belts 31. The excess portion at the top of the corn cob is discharged via a residue conveyor belt 33. A strip on the cutting belt 31, corresponding to the direction of corn cob movement... The side is equipped with cutting teeth 32 to cut the corn cob. The opening of the residue conveyor belt 33 corresponds to the upper end of the corn cob. At the same time, the movement direction of the cutting belt 31 when it contacts the corn cob corresponds to the movement direction of the residue conveyor belt 33, so that the excess part of the upper end of the corn cob can enter the residue conveyor belt 33. On the outer side of the residue conveyor belt 33, which corresponds to the movement direction of the cutting belt 31, there is a residue guide plate 34 for guiding the residue at the top of the corn cob into the residue conveyor belt 33. The residue guide plate 34 prevents excess corn cob residue from splashing and falling to the ground. By effectively utilizing the corn cob, two equal-length sections can be retained from one corn cob for planting, while the excess part is cut off and discharged, thereby effectively utilizing the corn cob while reducing material waste.

[0042] An opening mechanism for intercepting and removing the ends of jujube pits is connected to the outlet tube 9. This mechanism intercepts the jujube pits during transport and positions the lower end of the pit during interception. Then, pressing blocks 38 on the side press down on both ends of the pit, removing them and making the pit easier to germinate. A temporary storage shell 35 is connected to the outlet tube. The temporary storage shell 35 is a rectangular structure arranged at an angle. Temporary storage channels 36 are provided on the temporary storage shell 35 at positions corresponding to the outlet tube. The lower end of each temporary storage channel 36 is slidably connected to a vertically perpendicular... The intercepting plate 37 is arranged along the axis of channel 36. Under normal conditions, the intercepting plate 37 completely covers the temporary storage channel 36, so that the jujube pits are intercepted by the intercepting plate 37 when passing through the outlet tube. Since the lower end of the intercepted jujube pit is in contact with the upper end of the intercepting plate 37, the lower end of the jujube pit can be positioned. Then, the sharp points at both ends of the jujube pit can be removed by pressing block 38. After the sharp points are removed, water can directly contact the seed at both ends of the jujube pit, so that germination is faster. At the same time, the germinated embryo can extend more easily, thereby improving the survival rate. Then, the intercepting plate 37 is opened to allow the jujube pits with the sharp points removed to continue to be transported downwards.

[0043] The temporary storage housing 35 is provided with sliding grooves at the upper and lower ends of the temporary storage channel 36, respectively. A pressing block 38 is slidably connected in the sliding groove. The pressing block 38 is driven by a pressing motor to press the upper and lower ends of the date pit located in the temporary storage channel 36, thereby removing the sharp ends of the date pit. Because the two ends of the date pit are removed at the same time, even if one end is removed, the date pit will be blocked by the pressing block 38, so that the middle of the date pit will not move in height. This avoids displacement of the date pit after one end is removed, thus preventing the middle of the date pit from being displaced and the remaining end not being removed. When removing the two ends of the date pit, the end of the temporary storage housing 35 that is inclined upward is the end of the pressing block 38 that moves in the direction of movement. The side surface of the temporary storage housing 35 that is inclined downward is provided with a discharge port 39 at the position corresponding to the pressing block 38, so that the residue generated after pressing will be discharged from the discharge port 39.

[0044] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of the claims of this patent application.
