Description

Technical Field

[0001] The present invention relates to the technical field of agricultural planting, in particular to a jujube tree seedling raising device based on corn cobs. Background Art

[0002] Grafted jujube seedlings have more developed root systems and stronger adaptability than cuttings, and are currently the basic form of jujube seedling cultivation, mainly in the field. However, seedlings cannot usually be removed from field nurseries with soil balls, and the survival rate of afforestation is not high. Container seedling cultivation requires the purchase of more expensive substrates and then bagging them according to strict ratios, which is labor-intensive and costly.

[0003] Jujube seedling cultivation currently relies primarily on sowing jujube kernels to cultivate rootstocks, followed by grafting. The price of jujube kernels has remained high in recent years, reaching 800-1000 yuan per kilogram. The breakage rate during the pitting and seed production process is close to 10%, necessitating new approaches to improve economic efficiency. Corn cobs are readily available and inherently loose, retaining water and fertilizer. Proper processing and creative utilization of these materials offer a feasible, low-cost, and sustainable method for raising seedlings, ensuring high survival rates.

[0004] The present invention utilizes segmented corn cobs that are easy to obtain and low in cost to replace the high-cost container seedling medium, and uses processed perforated jujube pits instead of jujube kernels to protect the expensive jujube kernels from damage. The rationally designed mechanical planting device 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 corncob-based jujube tree seedling raising device which uses corncobs as a culture medium and carries out batch seedling raising of jujube trees.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0007] A jujube seedling raising device based on corn cobs includes a storage cylinder, which is divided into a cylindrical cylinder wall and a bottom plate. The outer side of the cylinder wall of the storage cylinder is rotatably connected to the support frame and the rotating shaft is arranged obliquely. A plurality of temporary storage grooves for storing jujube pits are provided on the side of the bottom plate facing the cylinder wall. The middle part of the temporary storage groove is semi-cylindrical and the two ends are conical. The middle axis of the temporary storage groove is staggered and arranged vertically with the axis of the storage cylinder. Each temporary groove is evenly spaced along the axis of the storage cylinder. An adsorption vent and a material outlet are respectively provided at the outer side surface of the bottom plate and the positions at the two ends of the temporary storage groove. One end of the temporary groove connected to the material outlet corresponds to the rotation direction of the storage cylinder. A fan-shaped suction disk is provided at the outer side of the bottom plate corresponding to each adsorption vent. The outer side of the bottom plate is connected to the material outlet. A fan-shaped guide plate is provided at the position corresponding to the outlet position, the fan-shaped guide plate cooperates with the fan-shaped suction plate and covers the annular area of the corresponding temporary storage tank movement, the fan-shaped guide plate is connected to a guide pipe that cooperates with the material guide outlet, and the lower end of the guide pipe is connected to a planting mechanism for planting the 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 guide pipe is provided on the side of the planting rod, a pressing rod is vertically slidably connected in the planting rod, the upper end of the pressing rod and the upper end of the planting rod are connected by a reset spring, and a limiting member for limiting the pressing rod is provided on the outside of the pressing rod.

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

[0009] This solution is suitable for batch industrial operations to carry out large-scale seedling cultivation. Corn cobs are used as culture substrates during the seedling cultivation process, which not only makes it easy to maintain good temperature and humidity during the seed germination process, but the corn cobs themselves can be used as fertilizers for cultivation. After the seeds germinate, the corn cobs are planted together with the seeds, which not only provides nutrition for the seeds, but also does not damage the fragile root system of the seeds during the transplanting process. The roots can be directly rooted in the corn cob material. The nutrients of the corn cobs will not be absorbed all at once in a short period of time after transplanting, and the nutrient supply can be maintained for a long time. During this process, the corn cobs can maintain good support to support the seedlings. Compared with traditional transplanting, the roots of the seedlings are more stable. At the same time, the loose and breathable structure of the corn cobs can also keep its roots well breathable. At the same time, the seedlings are not easy to fall over under the action of wind. At the same time, corn cobs are relatively simple and cheap to obtain. After planting, they can provide a certain amount of fertilizer to the root system and soil in the initial growth stage, thereby improving the survival rate of seedlings.

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

[0027] When using this embodiment, the seeds that need to be grown for seedlings are first screened, and the seeds for seedlings are selected from dates with full grains and good quality. Before sowing, the seeds are soaked and germinated, and the corn cobs to be used are pre-treated. The two ends of the corn cobs are removed and made into middle sections of the same length as seedling substrates. The corn cobs need to be sterilized before use, and then transported by a conveyor belt and wait for seeds to be implanted. During the transportation of the corn cobs by the conveyor belt, the corn cobs remain in a vertical state and their posture is stabilized by the conveyor belt to avoid shaking.

[0028] In the process of implanting seeds into corn cobs, the seeds to be planted are first placed in the storage tube 1. The storage tube 1 is a cylindrical structure with an open end. The middle part of the storage tube 1 is a cylindrical tube wall 2, and the lower end is closed by a circular bottom plate 3. A conical structure is used as a blocking piece at the upper end of the cylindrical tube wall 2. Because the cylindrical tube wall 2 needs to be kept in an inclined state when in use, the conical structure at the upper end opening can prevent the internal seeds from being discharged outward, and at the same time can accommodate more seeds. Its conical structure is a structure with a small top and a large bottom, with an open top and a lower end connected to the cylindrical tube wall 2. A ring-shaped driving gear ring is provided on the outside of the cylindrical tube wall 2. The outer side of the cylindrical tube wall 2 is rotatably connected to the support frame, and the driving gear ring is driven by a driving motor fixedly connected to the support frame, so that the cylindrical tube wall 2 can rotate at a uniform speed on the support frame.

[0029] On one side of the bottom plate 3 close to the cylindrical wall 2, there are provided with a plurality of transport components for transporting seeds in an annular arrangement, each transport component includes a plurality of temporary storage grooves 4 for temporarily storing jujube pits. The middle part of the temporary storage groove 4 is a semi-cylindrical structure, and the two ends of the semi-cylinder are conical structures with the tips facing outwards, so that the temporary storage groove 4 can better adapt to the structure of the jujube pit and thus better match the jujube pit structure while accommodating the jujube pit. The diameter of the cylindrical structure in the temporary storage groove 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, and the storage tube 1 is arranged inclined with an inclination angle ranging from twenty to forty-five degrees, and each temporary storage groove 4 is connected to an adsorption vent 5 for adsorbing jujube pits. By sucking air from the adsorption vent 5 on the outside, the position of the jujube pit entering the temporary storage groove 4 is fixed, so that when the bottom plate 3 rotates with the wall of the tube, it carries and only carries one jujube pit for movement, and the 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 staggered with the axis of the cylindrical barrel wall 2 and is arranged vertically. An adsorption vent 5 and a material outlet 6 are respectively provided at the end away from the cylindrical barrel wall 2 where the cylindrical structures at both ends of the temporary storage tank 4 are connected with the conical mechanism. The adsorption vent 5 and the material outlet 6 are respectively located at one end of the temporary storage tank 4, wherein the material outlet 6 is located at one end of the movement direction of the temporary storage tank 4 and an arc-shaped guide plate is provided on the outside of the temporary storage tank 4. The adsorption vent 5 is located at the end opposite to the movement direction of the temporary storage tank 4, so that when the jujube pit is in the temporary storage tank 4, one end of the jujube pit is located in the temporary storage tank 4 by the adsorption force generated by the adsorption vent 5, and then moves with the temporary storage tank 4. Even if the temporary storage tank 4 moves to the upper end of the inclined surface of the bottom plate 3, it will not fall.

[0031] A plurality of annular sealing rings 30 are provided on the outer surface of the bottom plate 3. The sealing rings 30 are respectively located on the outside of the adsorption vent 5 and the material outlet 6. A fan-shaped suction disk 7 is rotatably connected in the sealing ring 30. The fan-shaped suction disk 7 and the sealing ring 30 are slidably fitted together. The outer side of the fan-shaped suction disk 7 is fixedly connected to the support frame so that the position of the fan-shaped suction disk 7 remains unchanged. An air pump is connected to the outer side of the fan-shaped suction disk 7 so that the fan-shaped suction disk 7 always generates suction on the adsorption vent 5 within the coverage range, thereby preventing the jujube pits from falling during movement.

[0032] The fan-shaped air suction disc 7 is a fan-shaped structure, and its coverage angle range is 270 degrees. The coverage direction is the upper and lower ends of the obliquely arranged bottom plate 3 and the side through which the temporary storage tank 4 moves from the upper end to the lower end, and the overall coverage angle is 270 degrees, that is, when the temporary storage tank 4 passes through the coverage range of the fan-shaped air suction disc 7, suction will be generated, thereby adsorbing the jujube pits near the temporary storage tank 4, and the temporary storage tank 4 will adsorb one end of the jujube pit during the adsorption process, and the main body of the jujube pit will be sucked. Located in the temporary storage groove 4, the outer edge of the temporary storage groove 4 will guide the middle part of the jujube pit into the temporary storage groove 4, and the jujube pit will also adjust its position when it contacts with other jujube pits during the movement. Only when the posture of the jujube pit is adjusted so that one end is adsorbed and the middle part is located in the temporary storage groove 4 can most of the volume of the jujube pit be hidden in the temporary storage groove 4. In this way, when the rest of the jujube pits contact with the adsorbed jujube pit again, they will not have a pushing effect on the adsorbed jujube pit. At this time, the positioning of the jujube pit and the posture adjustment when the jujube pit is adsorbed are completed, which is convenient for the subsequent output of the jujube pit.

[0033] The fan-shaped guide plate 8 corresponds to the notch of the fan-shaped suction plate 7. When the temporary storage groove 4 on the bottom plate 3 carries the jujube pit and moves to the range of leaving the fan-shaped suction plate 7, it will pass through the fan-shaped guide plate 8 area. The fan-shaped guide plate 8 area has no adsorption force on the jujube pit. At the same time, when the temporary storage groove 4 moves to the fan-shaped guide plate 8 area, the material guide port 6 in the temporary storage groove 4 will be located at the obliquely downward end. Before leaving the adsorption, the jujube pit is located at the obliquely upward end of the temporary storage groove 4. After losing the adsorption force, the jujube pit will move to the material guide port 6 under the action of gravity, and the outer side of the material guide port 6 is connected to the guide pipe 9. When the temporary storage groove 4 moves to the fan-shaped guide plate 8 area, the material guide port 6 is arranged vertically, and the guide pipe 9 is arranged vertically and matched with the position of the material guide port 6. At this time, the adsorption effect on the jujube pit is released, and the jujube pit will fall into the guide pipe 9 under the action of gravity and be guided out, and then be planted through the planting mechanism.

[0034] On one side of the bottom plate 3 facing the cylindrical wall 2, a protective sheet with an arc-shaped structure and protruding outward is provided at the position corresponding to each material outlet 6, so that the protective sheet can guide the material during the rotation of the bottom plate 3 and prevent the date pits from entering the material outlet 6.

[0035] The export tubes 9 are multiple and correspond to the number of transport components of the annular structure on the bottom plate 3. Each export tube 9 corresponds to a transport component of the annular structure, so that the jujube kernels output by each transport component can be planted. The planting mechanism includes a vertically arranged and 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, so that the planting rod 10 can perform vertical reciprocating motion under the action of the telescopic rod. The telescopic rod can be driven by hydraulic pressure, pneumatic pressure or electric drive, as long as the planting rod 10 can achieve reciprocating motion in the upper and lower positions. A feeding port 11 is provided on the side of the planting rod 10, and the protruding end of the export tube 9 corresponds to the feeding port 11, so that the jujube kernels exported from the export tube 9 will enter the planting rod 10 from the feeding port 11, and the upper end of the planting rod 10 is vertically slidably connected with a pressing rod 1 The upper end of the planting rod 10 is connected to the upper end of the pressing rod 12 by a return spring 13, and 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 extends upward with a limit frame 19 for limiting the upward movement distance of the upper end of the pressing rod 12. In the initial state, the feeding port 11 on the side of the planting rod 10 cooperates with the outlet of the outlet pipe 9. At this time, the pressing rod 12 extends upward under the action of the return spring 13 to contact the limit frame 19, and the lower end of the pressing rod 12 extends to the inside of the planting rod 10 and is located above the feeding port 11, so that the pressing rod 12 will not block the jujube pit from entering the planting rod 10, and the lower end of the planting rod 10 is rotatably connected to the closing cover 22. The closing cover 22 prevents the residue in the corn cob from entering the planting rod 10 when the planting rod 10 is pressed downward. A limit plate for cooperating with the pressing rod 12 is rotatably connected to the support frame outside the planting rod 10.

[0036] Due to the structure of the corncob itself, its central part is relatively soft and located in the middle, so during the planting process, the seeds are planted in the middle of the corncob, and the diameters of the planting rod 10 and the closing cover 22 are smaller than the soft cylindrical structure of the corncob, so that the seeds can be planted conveniently. The closing cover 22 is rotatably connected to the lower end of the planting rod 10, and the outer edge of the closing cover 22 covers the outer edge of the lower end surface of the planting rod 10, so that when the planting rod 10 is pressed downward to enter the softer part in the middle of the corncob, the closing cover 22 can first contact the middle of the corncob, so that the residue of the corncob will not enter the hollow part of the planting rod 10. One end of the upper end surface of the closing cover 22 is rotatably connected to the lower end surface of the planting rod 10, and a vertically arranged connecting groove is provided at the side surface of the planting rod 10 corresponding to the rotating connection portion of the closing cover 22. An elastic rope 24 is passed through the connecting groove 23, and the lower end of the elastic rope 24 is fixedly connected to the side of the upper end surface of the closing cover 22 facing the axis of the planting rod 10. The other end of the elastic rope 24 passes through the connecting groove 23 upward and is fixedly connected to the support frame, so that the elastic rope 24 always has a tendency to close the closing cover 22 under the action of elastic force. In this way, no matter what position the planting rod 10 is in, the elastic rope 24 always has a driving force to close the closing cover 22.

[0037] The lower end of the limit member 14 is rotatably connected to the support frame outside the planting rod 10. A limit block 15 is provided on the side of the support frame close to the planting rod 10 to limit the movement angle of the limit member 14, and a pressing spring 16 is provided on the side of the support frame away from the limit member 14 to press the limit member 14. The limit member 14 is always kept vertical by the combined action of the pressing spring 16 and the limit block 15, and can move its upper end toward the side away from the planting rod 10 under the action of external force. The limit member 14 is an n-type structure, and the upper end of the limit member 14 is fixedly connected to the first guide block 17. The upper end of the first guide block 17 The surface is arranged to extend obliquely downward toward the planting rod 10, and the lower end surface of the first guide block 17 is a horizontal surface when the limiter 14 is vertical. A second guide block 18 is fixedly connected below the first guide block 17, and the lower end surface of the second guide block 18 is arranged to extend obliquely upward toward the planting rod 10. There is a gap between the first guide block 17 and the second guide block 18, and the upper end of the pressing rod 12 is fixedly connected to a first matching block 20 that cooperates with the first guide block 17, and the upper end of the planting rod 10 is fixedly connected to a second matching block 21 that cooperates with the second guide block 18. When the pressing rod 12 moves downward with the planting rod 10 to the planting rod When the planting rod 10 is in the set position, the first matching block 20 will move and pass over the first guide block 17 in the limit plate, and then the limit plate will be 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, but will move upward when the planting rod 10 is reset. At this time, the pressing rod 12 will not move because the upward movement is blocked. At this time, the seeds located in the planting rod 10 will remain in place under the obstruction of the lower end of the pressing rod 12, and the closing cover 22 at the lower end of the planting rod 10 is forced to open, so that the seeds remain 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 10 and the pressing rod 12 will be compressed and stored until the second matching block 21 at the upper end of the planting rod 10 moves to contact the second guide block 18, and the second matching block 21 pushes the second guide block 18, so that the upper end of the limiting member 14 moves toward the side away from the planting rod 10. After the upper end of the limiting member 14 moves toward the side away from the planting rod 10, the first guide block 17 loses its limiting effect on the first matching block 20, and the pressing rod 12 moves upward and resets under the action of the return spring 13, thereby completing one planting action, and then waiting for the next planting action.

[0038] A closure piece 25 extending upward is provided on the upper end surface of the closing cover 22 and located on the outer side of the rotating connection portion, and a closure groove 26 for accommodating the closure piece 25 is provided on the lower end surface of the planting rod 10 at a position corresponding to the position of the closure piece 25. In this way, when the closing cover 22 rotates, the closure piece 25 will be hidden in the closure groove 26. When the closing cover 22 does not move, the closure piece 25 blocks residue from entering the rotating connection portion, thereby preventing the rotating connection portion from being blocked.

[0039] There are two planting methods for the planting rod 10. The first is that the planting rod 10 performs regular vertical reciprocating motion and plants according to the rotation speed of the storage tube 1 and the corresponding number of temporary storage slots 4. Each time the planting rod 10 moves downward, the new corn cob is moved to the position corresponding to the planting rod 10 through the conveyor belt. This is a feedback-free movement method. The advantage is that it is easy to operate, and the disadvantage is that there is no feedback. If the seeds are not adsorbed and transported in the temporary storage slot 4, the planting operation is still carried out, which may easily lead to no planting. The second method is to set a touch sensor at the position corresponding to the planting rod 10 on the upper end surface of the closing cover 22. After the seeds enter the planting rod 10, they will fall on the upper end of the closing cover 22. At this time, the touch sensor will sense the seed falling. At this time, by moving the planting rod 10 downward and planting, there will be no vacancies in the planting. The disadvantage is that the electronic control is easy to be damaged. The corresponding method should be used for planting according to the needs of use.

[0040] Regardless of the planting method, the conveyor belt transports the corn cobs. The conveyed corn cobs are required to be cut off from the head and tail and only retain one end in the middle, and the height of each corn cob is the same. During the transportation of each corn cob through the conveyor belt, it must be kept clamped when it moves under the planting rod 10 to prevent the corn cob from being synchronously driven upward when the planting rod 10 moves upward. A limit plate can be provided on the outside of the conveyor belt to maintain the clamping action of the conveyor belt on the corn cob by pressing the limit plate to prevent the corn cob from moving. Each conveyor belt adopts intermittent movement, and the distance of each movement is the spacing between the clamped corn cobs. At the same time, the transportation 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 slots 4.

[0041] When using corn cobs, it is wasteful to use only one end of the corn cob or only a section of the lower end. At the same time, manual cutting is likely to result in high labor costs and waste of corn cob raw materials. Therefore, when using a corn cob, it is adopted to divide a corn cob into two sections of equal height for use. The upper and lower ends of the corn cob are clamped respectively during the conveying process by two parallel material conveyor belts 28. The lower ends of each corn cob are in the same plane. After the corn cob is cut, the remaining length is divided into two sections, namely the height of the cutting belt 31 between the lower end of the corn cob and the two material conveyor belts 28, and the height between the two cutting belts 31. The excess part at the upper end of the corn cob is discharged through the residue conveyor belt 33. A section on the cutting belt 31 corresponding to the movement direction of the corn cob is The side is provided with cutting teeth 32, which are used 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 in contact with 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. The outer side of the residue conveyor belt 33 corresponding to the movement direction of the cutting belt 31 is provided with 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 on the ground. By effectively utilizing the corn cob, two equal-length sections of a corn cob can be retained for planting, and the excess part can be cut and exported, thereby effectively utilizing the corn cob while reducing material waste.

[0042] An opening mechanism is connected to the outlet pipe 9 for intercepting the jujube pit and removing the two ends of the jujube pit. The opening mechanism intercepts the jujube pit during the transportation process and positions the lower end of the jujube pit when intercepting. Then, the upper and lower ends of the jujube pit are pressed by the pressing blocks 38 on the side. The upper and lower ends of the jujube pit are removed by the pressing force, making it easier for the jujube pit to germinate after the upper and lower ends are removed. A temporary storage shell 35 is connected to the outlet pipe. The temporary storage shell 35 is a rectangular parallelepiped structure and is arranged obliquely. Temporary storage channels 36 are respectively opened at the positions corresponding to the outlet pipe positions. The lower ends of the temporary channels 36 are slidably connected to the temporary storage channels 36. The interception piece 37 is arranged on the axis of the channel 36. Under normal circumstances, the interception piece 37 completely covers the temporary storage channel 36, so that the jujube pit will be intercepted by the interception piece 37 when passing through the outlet pipe. Since the lower end of the intercepted jujube pit is in contact with the upper end of the interception piece 37, the lower end of the jujube pit can be positioned, so that the tips of the upper and lower ends of the jujube pit can be removed by pressing the block 38. After the tips are removed, the upper and lower ends of the jujube pit can allow water to directly contact the seeds, so that germination is faster. At the same time, the germinated embryo can be more convenient to extend, thereby improving the survival rate. Then the interception piece 37 is controlled to open, so that the jujube pit with the tip removed continues to be transported downward.

[0043] The temporary storage shell 35 is provided with a slide groove at the corresponding positions of the upper and lower ends of the temporary storage channel 36, and a pressing block 38 is slidably connected in the slide groove. The outer side of the pressing block 38 is driven by a pressing motor to press the upper and lower ends of the jujube pit located in the temporary storage channel 36, so that the tips of the two ends of the jujube pit are removed. Because the two ends of the jujube pit are removed at the same time, even if one end has been removed, the jujube pit will be blocked by the pressing block 38, so that the middle part of the jujube pit will not move in height, thereby avoiding the displacement of the jujube pit after one end is removed, thereby avoiding the displacement of the middle part of the jujube pit while the remaining end is not removed. When removing the two ends of the jujube pit, the upward end of the temporary storage shell 35 is the end of the movement direction of the pressing block 38, and a discharge port 39 is provided on the downward side surface of the temporary storage shell 35 corresponding to the position of the pressing block 38, so that the residue produced after pressing will be discharged from the discharge port 39.

[0044] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the claims of this patent application.
