Description

Technical Field

[0001] This utility model relates to the field of agricultural equipment technology, and in particular to a special cabinet for agricultural planting with a storage box. Background Technology

[0002] In agricultural planting, it is necessary to preserve and pre-treat plant seeds, which requires the use of specialized seed preservation cabinets. However, most current seed preservation cabinets have relatively simple structures and limited functions, making them unsuitable for seed preservation. During the initial treatment of plant seeds, timed sunlight exposure is required. The current practice involves removing the seeds and placing them under a fluorescent lamp for timed exposure. This repeated handling not only results in seed loss but is also inconvenient, time-consuming, and labor-intensive, hindering seed preservation.

[0003] For example, a Chinese patent document discloses an agricultural planting cabinet with storage boxes (publication number: CN207821450U). Although this patent allows the storage drawers inside storage cabinets one, two, three, and four to be pulled out so that the drawers face the fluorescent light panel at the bottom of the simulated fluorescent light device, and then the fluorescent light on / off button inside the switch is pressed, thus enabling the power supply to provide power to the fluorescent light panel, and under the normal illumination of the fluorescent light panel, it can simulate sunlight irradiation for the seeds. Therefore, the design is more reasonable. Depending on the type of seed, the irradiation intensity of the fluorescent light panel can be adjusted by pressing the light intensity adjustment button.

[0004] However, each time the storage cabinet is illuminated, it needs to be manually opened and closed, and then the next cabinet needs to be opened. The operator needs to be present throughout the process, making the overall operation quite cumbersome. Furthermore, since the storage cabinets are of different heights, but the fluorescent light panel is at a fixed height, the seeds inside the lower storage cabinets are farther away when being illuminated. Therefore, the power of the fluorescent light panel needs to be increased to compensate for the light attenuation caused by the distance by increasing the overall light intensity, which leads to a serious increase in energy consumption. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies. Currently, when irradiating seeds in storage cabinets, manual opening and closing is required, which is not only cumbersome but also results in high energy consumption due to high-power irradiation.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: An agricultural planting cabinet with a storage box includes a storage cabinet body, and an illumination height adjustment mechanism is provided on one side of the storage cabinet body; The irradiation height adjustment mechanism includes a column, one side of which is fixedly connected to one side of the storage cabinet. A movable groove is provided on the front of the column. A first servo motor is fixedly installed at the upper end of the column. A first lead screw is fixedly installed on the output shaft of the first servo motor through a coupling. One end of the first lead screw passes through the interior of the movable groove and is rotatably connected to the inner bottom wall of the movable groove through a bearing. A first threaded block is threadedly connected to the external thread of the first lead screw. The front of the storage cabinet is equipped with an automatic opening and closing mechanism.

[0007] Preferably, the outer side of the first threaded block is slidably connected to the inner wall of the moving groove, a connecting block is fixedly connected to the front side of the first threaded block, and slots arranged in a linear array are provided on the front side of the storage cabinet.

[0008] Preferably, a storage box is movably inserted into the inner wall of the slot, a handle is fixedly connected to the front of the storage box, and a humidity sensor is fixedly installed on one inner wall of the storage box.

[0009] Preferably, the automatic opening and closing mechanism includes a lifting platform, one side of which is fixedly connected to one end of the connecting block, a fluorescent lamp plate is fixedly installed at the lower end of the lifting platform, and a second servo motor is fixedly installed at the upper end of the lifting platform.

[0010] Preferably, the output shaft of the second servo motor is fixedly mounted with a second lead screw via a coupling, and a support block is rotatably connected to one end of the second lead screw via a bearing. The lower end of the support block is fixedly connected to the upper end of the lifting platform.

[0011] Preferably, the second lead screw is externally threaded with a second threaded block, the lower end of the second threaded block is fixedly connected with a movable bracket, the inner walls of both ends of the movable bracket are slidably fitted with symmetrically distributed guide rods, and the two ends of the guide rods are fixedly connected with symmetrically distributed fixing blocks.

[0012] Preferably, one end of each of the two fixed blocks is fixedly connected to one side of the lifting platform, and a servo electric cylinder is fixedly installed on the inner bottom wall of the movable support. One end of the piston rod of the servo electric cylinder passes through to the bottom of the movable support and is fixedly connected to an L-shaped insert plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are: In this invention, the distance between the fluorescent lamp plate and the storage box can be precisely adjusted through the irradiation height adjustment mechanism, the first servo motor and the first lead screw drive, to adapt to the lighting requirements of storage boxes of different heights and avoid excessive energy consumption due to distance differences. The automatic opening and closing mechanism relies on the second servo motor and servo electric cylinder to realize the automatic opening and closing of the storage box, replacing repeated manual operation. Through the linkage of the two mechanisms, not only is the intensity of manual labor greatly reduced, but also the energy consumption requirement is reduced. Furthermore, it can intelligently trigger irradiation according to the seed humidity, thus extending the seed storage time. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0017] To facilitate understanding of this utility model, a more comprehensive description of this utility model will be provided below with reference to relevant embodiments, and several embodiments of this utility model will be given. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of this utility model more thorough and complete.

[0018] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0020] Example like Figures 1-5 As shown, this utility model provides a technical solution: an agricultural planting cabinet with a storage box, including a storage cabinet body 1 and an irradiation height adjustment mechanism on one side of the storage cabinet body 1, which provides precise height adaptation and intelligent triggering guarantee for seed irradiation, and completely solves the energy consumption and efficiency problems of traditional fixed height design.

[0021] The core component column 2 is fixed to the storage cabinet 1. The movable groove 21 on its front provides a guide channel for the movement of the first threaded block 24. The first servo motor 22 installed at the upper end drives the first lead screw 23 to rotate through the coupling. With the help of the transmission characteristics of the lead screw and the threaded block, the first threaded block 24 can be smoothly raised and lowered along the inner wall of the movable groove 21.

[0022] The height of the fluorescent light panel 31 can be precisely adjusted according to the different heights of the storage boxes 27, such as the upper storage box 27 being 10cm from the top and the lower storage box 27 being 50cm from the top, so that the illumination distance is always kept within the optimal range. This avoids the problem in traditional fixed-height designs where the lower storage box 27 needs to increase its power due to its greater distance, while the upper storage box 27 is wasted due to its shorter distance. Long-term use can significantly reduce the energy consumption cost of agricultural production.

[0023] The connecting block 25 fixed on the front of the first threaded block 24 synchronously transmits the height adjustment action to the lifting platform 3, ensuring the consistency of linkage between the fluorescent light panel 31 and the height adjustment mechanism. The linear array slot 26 opened on the front of the storage cabinet 1 provides a stable insertion and removal space for the storage box 27. The handle 28 on the front of the storage box 27 not only facilitates manual emergency operation, but also meets the docking requirements of the L-shaped insert plate 310 of the automatic opening and closing mechanism.

[0024] The humidity sensor 29 installed on the inner wall of the storage box 27 can collect the humidity data of the seeds in the box in real time. When the monitored value exceeds the preset threshold, it automatically sends a signal to the PLC controller to trigger the irradiation process. There is no need for regular manual inspection, which reduces the cost of manual operation. At the same time, it avoids the seeds from getting damp and moldy due to human negligence, ensures the stability of the seed storage environment, and extends the seed storage period.

[0025] The automatic opening and closing mechanism on the front of the storage cabinet 1 enables unmanned automatic operation of the storage box 27, avoiding seed loss and significantly improving irradiation efficiency. The lifting platform 3, as the core load-bearing component, is fixed to the connecting block 25 on one side to ensure synchronous movement with the height adjustment mechanism. The fluorescent light panel 31 installed at the lower end uses an LED energy-saving light source, and the light intensity can be precisely adjusted according to the seed type via a PLC controller.

[0026] For example, the irradiation level is set to 3000 lux for light-sensitive vegetable seeds and 5000 lux for corn seeds with high light requirements. This ensures the irradiation effect while further reducing energy consumption. The second servo motor 32 installed at the top drives the second lead screw 33 to rotate through a coupling. The support block 34 fixes one end of the second lead screw 33 to prevent radial displacement when the lead screw rotates, thus ensuring transmission stability.

[0027] The second threaded block 35, which is externally threaded to the second lead screw 33, drives the movable bracket 36, which is fixed at the lower end, to move laterally along the guide rod 37. The guide rod 37 is fixed to the lifting platform 3 by the fixing blocks 38 at both ends, forming a stable lateral guide structure.

[0028] To ensure that the L-shaped insert plate 310 can be accurately aligned with the slot of the handle 28, and to avoid the problem of the storage box 27 being unable to be opened or damaged due to misalignment, the servo electric cylinder 39 installed on the inner bottom wall of the moving bracket 36 drives the L-shaped insert plate 310 to move up and down through the extension and retraction of the piston rod, thereby completing the quick engagement and disengagement with the handle 28, replacing the traditional manual operation of pulling out the storage box 27.

[0029] To avoid seed spillage due to shaking and collision during manual handling, and to meet the seed processing needs of large-scale agricultural planting.

[0030] In addition, the entire automatic opening and closing mechanism is precisely controlled by a PLC controller. The entire process, from "L-shaped insert plate 310 docking with handle 28 - snap-pull out storage box 27 - irradiate - push back storage box 27 L-shaped insert plate 310", requires no manual intervention and can realize batch continuous processing of multiple storage boxes 27. It is especially suitable for centralized seed preservation operations in large farms and seed breeding bases, promoting the automation and intelligent upgrading of agricultural planting.

[0031] It should be noted that the electrical components mentioned above are all existing mature technologies. Appropriate models and power can be selected based on the technical knowledge of those skilled in the art, and they are controlled by PLC controllers, which are existing mature technologies. Therefore, they will not be described in detail again.

[0032] The working process of this utility model: Step 1: Before use, the seed irradiation time is preset using an external PLC controller and time relay. At the same time, according to the different humidity tolerance of seeds, a humidity threshold is set in the PLC controller. When the humidity sensor 29 detects that the humidity of the seeds in the storage box 27 is greater than the threshold, the automatic irradiation process will be triggered. When the seeds need to be irradiated, the first servo motor 22 starts. The output shaft of the first servo motor 22 drives the first lead screw 23 to rotate through the coupling. Since the first threaded block 24 connected to the external thread of the first lead screw 23 is slidably connected to the inner wall of the moving groove 21, the rotation of the first lead screw 23 will cause the first threaded block 24 to move down along the inner wall of the moving groove 21. The connecting block 25 fixedly connected to the front of the first threaded block 24 will then drive the lifting platform 3 to descend until the lifting platform 3 is adjusted to the corresponding height of the storage box 27 to be irradiated. At this time, the first servo motor 22 stops working, completing the precise adjustment of the irradiation height and ensuring that the distance between the fluorescent light board 31 and the storage box 27 is appropriate, avoiding insufficient light intensity or waste of power due to improper distance. Step two, next, the second servo motor 32 starts, and the output shaft of the second servo motor 32 drives the second lead screw 33 to rotate forward through the coupling. The second threaded block 35, which is externally threaded to the second lead screw 33, will move along the axis of the second lead screw 33 when the second lead screw 33 rotates forward. The movable bracket 36, which is fixedly connected to the lower end of the second threaded block 35, then drives the L-shaped insert plate 310 to move above the front handle 28 of the storage box 27. At this time, the servo electric cylinder 39 is started, and its piston rod extends, driving the L-shaped insert plate 310 to move downward and insert into the inner wall of the handle 28. Subsequently, the second servo motor 32 drives the second lead screw 33 to reverse, and the second threaded block 35 moves in the opposite direction. Through the cooperation of the L-shaped insert plate 310 and the handle 28, the storage box 27 is pulled to the outside, realizing the automatic opening of the storage box 27. Step 3: After the storage box 27 is opened, the fluorescent light panel 31 is turned on. The light emitted by the fluorescent light panel 31 irradiates the seeds in the storage box 27. When the preset irradiation time is reached, the second servo motor 32 drives the second lead screw 33 to rotate forward again. The second threaded block 35 drives the moving bracket 36 and the L-shaped insert plate 310 to move in the opposite direction. With the help of the handle 28, the storage box 27 is pushed back to its original position, realizing the automatic closing of the storage box 27. Afterwards, the piston rod of the servo electric cylinder 39 retracts, driving the L-shaped insert plate 310 to reset, completing the irradiation process of a single seed in the storage box 27. In addition, when the humidity sensor 29 in a storage box 27 detects that the seed humidity is greater than the preset value, it will send a signal to the PLC controller. The PLC controller will trigger the above irradiation process to irradiate the seeds in the storage box 27, reduce the seed humidity, thereby increasing the seed storage time and ensuring seed quality.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
