Description

Technical Field

[0001] This utility model belongs to the field of chili cultivation technology, and specifically relates to a chili seedling cultivation device. Background Technology

[0002] In the early stages of chili seed cultivation, a series of breeding pretreatments are required to effectively block pathogens carried by the seeds and reduce the risk of disease occurrence during the plant's growth period. The traditional breeding process mainly includes the following steps: The first step is seed disinfection. Because various pathogens easily adhere to the surface of chili seeds, they need to be disinfected with chemicals before germination to remove potential hazards: first, soak the seeds in a 0.1% potassium permanganate solution for 10 minutes to inactivate the viruses; then, soak them in a 0.1% copper sulfate solution for the same amount of time to completely kill any remaining viruses.

[0003] Next, the seeds will undergo soaking. After disinfection, the seeds are rinsed with clean water and placed in 55℃ hot water. During this time, the water is stirred continuously to ensure even heating. Once the water temperature naturally drops to around 30℃, the stirring is stopped, and the seeds are allowed to continue soaking for 5-6 hours. This process further kills any latent pathogens and softens the seed coat, creating conditions for subsequent germination.

[0004] Finally, there is the germination stage. After soaking, the seeds are removed and placed in a constant temperature incubator at 25-30℃ in the dark to germinate. During germination, the seeds should be turned over every 4-5 hours and rinsed with clean water once a day until they sprout.

[0005] However, in the process of connecting the above pretreatment steps, it is still necessary to manually retrieve the pepper seeds in a loose, soaking state and transfer them to the next treatment solution. This repeated retrieval and transfer process causes mechanical damage to the pepper seeds, even destroying the nascent embryos, ultimately leading to a decrease in seed germination rate and affecting subsequent cultivation results. Utility Model Content

[0006] The purpose of this invention is to provide a chili seedling cultivation device, thereby overcoming the problem of decreased germination rate caused by repeated harvesting during chili seedling cultivation. The specific technical solution is as follows: A chili seedling cultivation device includes multiple processing cylinders, a net cylinder, a lifting mechanism, a moving mechanism, and a driving mechanism. The multiple processing cylinders are arranged linearly, the net cylinder is positioned above the processing cylinders, and the lifting mechanism is connected to the net cylinder. The moving mechanism includes a guide rail, on which rollers are provided. A connecting plate and a connecting rod are connected to the rollers. The connecting plate is connected to the lifting mechanism, and the connecting rod is connected to the driving mechanism. A position detection component and an alarm are radially connected to the processing cylinder along the circular opening at the upper end of the processing cylinder. An extension rod is radially provided on the mesh cylinder along the circular opening at the upper end of the mesh cylinder. The extension rod is connected to the lifting mechanism. A trigger is connected to the extension rod. The trigger is located directly above the position detection component.

[0007] Preferably, two support rods are symmetrically connected to the mesh cylinder, and a base plate is connected to the upper end of the two support rods. The base plate is connected to the lifting mechanism.

[0008] Preferably, the lifting mechanism includes a lifting cylinder, the output end of which is connected to the mesh cylinder, and a first connecting block and a second connecting block are connected to the lifting cylinder, the first connecting block and the second connecting block being respectively connected to the connecting plate.

[0009] Preferably, the connecting plate includes two first connecting plates, and a second connecting plate is connected to the same side of the two first connecting plates. The lifting cylinder is disposed between the two first connecting plates, and the first connecting plates are used to connect with the first connecting block and the second connecting block.

[0010] Preferably, four guide rails are provided, wherein two of the guide rails are arranged in a rectangular pattern, two of the guide rails are distributed left and right in the upper row, and the other two guide rails are distributed left and right in the lower row. The guide rails in the upper and lower rows are aligned in the vertical direction. Rolling grooves are provided on the guide rails, and the rollers are disposed in the rolling grooves. One of the guide rails in the upper row is provided with a sliding groove, and the connecting rod on the roller extends out from the sliding groove.

[0011] Preferably, it also includes a mounting frame, the lifting mechanism, the moving mechanism and the driving mechanism are connected to the mounting frame, and the plurality of processing cylinders are disposed below the mounting frame.

[0012] Preferably, the drive mechanism includes a lead screw with a nut connected to it, one end of the lead screw being connected to a motor, and the other end of the lead screw being connected to a mounting base.

[0013] Compared to existing technologies, this invention uses multiple treatment cylinders: one containing potassium permanganate solution, one containing copper sulfate solution, one containing clean water, and one containing hot water. A moving mechanism moves a mesh cylinder on a guide rail. When the moving mechanism moves above the cylinder containing the potassium permanganate solution, a position detection component detects a signal and controls the mechanism to continue moving, stopping the mesh cylinder above the potassium permanganate cylinder. Then, a lifting mechanism is controlled to insert the mesh cylinder containing chili seeds into the treatment cylinder, completing the soaking process. After soaking in the potassium permanganate solution, the lifting mechanism removes the mesh cylinder containing the chili seeds from the potassium permanganate solution cylinder. The moving mechanism then continues moving the mesh cylinder. Similarly, when the mesh cylinder moves above the cylinder containing the copper sulfate solution, a position detection component detects a signal and controls the moving mechanism to continue moving, stopping the mesh cylinder above the copper sulfate cylinder. Then, a lifting mechanism is controlled to insert the mesh cylinder containing the chili seeds into the treatment cylinder, completing the copper sulfate solution soaking process. In this way, the net cylinder is sequentially inserted into treatment cylinders containing potassium permanganate solution, copper sulfate solution, clean water, and hot water, completing the seed pretreatment during the cultivation of chili seedlings. Throughout the entire transfer process, there is no need to repeatedly retrieve the chili seeds.

[0014] Compared with the prior art, the present invention has the following advantages: the pretreatment of chili seeds is completed by carrying the chili seeds in a net cylinder. The seeds are always placed in the net cylinder, eliminating the need for repeated manual retrieval, reducing mechanical damage to the chili seeds, effectively protecting the integrity of the seed embryo, and significantly improving the seed germination rate and subsequent seedling survival rate.

The embodiments of this utility model will now be described based on its overall structure.

[0021] Figure 1-4 These are, respectively, the front view, side view, top view, and rear view of the chili seedling cultivation device provided in this embodiment. Figure 5This is a plan view of the connection structure between the lifting and moving mechanisms of the chili seedling cultivation device. Figure 6 and Figure 7 This is a 3D diagram of the connection structure between the lifting and moving mechanisms of the chili seedling cultivation device. (See attached diagram.) Figures 1-7 A chili seedling cultivation device includes multiple processing cylinders 1, a net cylinder 2, a lifting mechanism 3, a moving mechanism 4, and a driving mechanism 5. The multiple processing cylinders 1 are arranged linearly, the net cylinder 2 is located above the processing cylinders 1, and the lifting mechanism 3 is connected to the net cylinder 2.

[0022] The moving mechanism 4 includes a guide rail 41, on which a roller 42 is provided. A connecting plate 43 and a connecting rod 44 are connected to the roller 42. The connecting plate 43 is connected to the lifting mechanism 3, and the connecting rod 44 is connected to the driving mechanism 5.

[0023] The processing cylinder 1 is radially connected to a position detection component 6 and an alarm 10 along the circular opening at the upper end of the processing cylinder 1. The mesh cylinder 2 is radially provided with an extension rod 7 along the circular opening at the upper end of the mesh cylinder 2. The extension rod 7 is connected to the lifting mechanism 3. A trigger 8 is connected to the extension rod 7. The trigger 8 is located directly above the position detection component 6.

[0024] In specific implementations, the position detection component 6 and the matching trigger 8 can be used in various combinations. For example, in this embodiment, the position detection component 6 can be a proximity switch, or a Hall effect proximity switch, with the trigger 8 being a magnetic trigger. When the magnetic trigger moves to the position of the Hall effect proximity switch, the magnetic field of the magnetic trigger acts on the Hall element, reversing the Hall voltage, and the switch outputs a signal accordingly. This embodiment is only an illustrative example of the position detection component 6 and the trigger 8; in other optional implementations, various choices are possible.

[0025] In the specific implementation plan, the alarm 10 is set as an audible and visual alarm.

[0026] The position detection component 6 is disposed radially along the circular opening at the upper end of the processing cylinder 1, and the trigger 8 is disposed radially along the circular opening at the upper end of the mesh cylinder 2. This ensures that when the mesh cylinder 2 moves above the processing cylinder 1, the trigger 8 triggers the position detection component 6 to detect the position, and the mesh cylinder 2 is directly above the processing cylinder 1, preventing significant displacement of the mesh cylinder 2. See Figure 5In a specific implementation, four guide rails 41 are provided. Two of the guide rails 41 are arranged in a rectangular pattern, with two guide rails 41 distributed horizontally in the upper row and the other two guide rails 41 distributed horizontally in the lower row. The upper and lower rows of guide rails 41 are aligned vertically. Each guide rail 41 is provided with a rolling groove 410, and a roller 42 is disposed within the rolling groove 410. One of the guide rails 41 in the upper row is provided with a sliding groove 411, and a connecting rod 44 on the roller 42 extends out of the sliding groove 411. When the connecting rod 44 extends out of the sliding groove 411, the connecting rod 44 does not contact the sliding groove 411.

[0027] See Figure 1 In a specific implementation, two support rods 21 are symmetrically connected to the mesh cylinder 2, and a base plate 22 is connected to the upper end of the two support rods 21. The base plate 22 is connected to the lifting mechanism 3. A mesh cover is connected to the lower end of the mesh cylinder 2. The mesh cylinder 2 is used to hold the chili seeds to be processed. When it is necessary to remove the processed chili seeds from the mesh cylinder 2, the mesh cover can be opened, which is simple, convenient and practical.

[0028] In a specific implementation plan, the lower end of the treatment cylinder 1 is connected to a liquid outlet pipe, and a valve is provided on the liquid outlet pipe to facilitate the replacement of the treatment liquid in the treatment cylinder 1.

[0029] See Figure 5 In a specific implementation, the lifting mechanism 3 includes a lifting cylinder 31, the output end of which is connected to the mesh cylinder 2. A first connecting block 32 and a second connecting block 33 are connected to the lifting cylinder 31, and the first connecting block 32 and the second connecting block 33 are respectively connected to the connecting plate 43.

[0030] See Figure 5 , Figure 6 and Figure 7 In a specific implementation, the connecting plate 43 includes two first connecting plates 431, and a second connecting plate 432 is connected to the same side of the two first connecting plates 431. The lifting cylinder 31 is disposed between the two first connecting plates 431, and the first connecting plate 431 is used to connect with the first connecting block 32 and the second connecting block 33.

[0031] In a specific implementation plan, a mounting frame 9 is also included, the lifting mechanism 3, the moving mechanism 4 and the driving mechanism 5 are connected to the mounting frame 9, and a plurality of processing cylinders 1 are arranged below the mounting frame 9.

[0032] In a specific implementation, the drive mechanism 5 is disposed on the side of the moving mechanism 4. The drive mechanism 5 includes a lead screw 51, a nut 52 connected to the lead screw 51, one end of the lead screw 51 connected to a motor 53, and the other end of the lead screw 51 connected to a mounting base 54. The nut 52 is connected to the connecting rod 44. The When the lead screw 51 rotates, the lead screw nut 51 can move in the horizontal direction, thereby driving the roller 42 to roll.

[0033] In a more preferred embodiment, the drive mechanism 5 is positioned above the moving mechanism 4, and the wire nut 52 is connected to the first connecting block 32 at the upper end of the lifting cylinder 31 via a connecting rod, for driving the lifting mechanism 3 and the mesh cylinder 2 to move.

[0034] The moving mechanism 4 is equipped with four rollers 42, symmetrically arranged at both ends of the lifting cylinder 31. This allows the load to be evenly distributed across the rollers 42, resulting in a more reasonable load distribution and reduced power loss. The rollers 42 and the guide rail 41 experience rolling friction, which significantly reduces power loss and improves the smoothness of the device's movement.

[0035] This embodiment also provides a method for using the chili seedling cultivation device, as detailed below: 1. The lifting cylinder 31, lead screw 51, position detection component 6, and alarm 10 in the device are connected to the actuator in the following specific ways: The actuator includes a PLC controller. The digital output port of the PLC is connected to the control terminal of the alarm through a relay. After the PLC receives the position detection signal, the control output port is turned on, triggering the alarm.

[0036] Position detection component 6 is configured as a proximity switch component. The proximity switch outputs a digital signal, and the signal line of the proximity switch component is connected to the digital input port of the PLC. The positive and negative terminals (brown / blue) of the component's power supply are connected to an external power source. When an object moves to the designated position, the component outputs a signal, which the PLC receives through the input port as a trigger condition for subsequent actions.

[0037] The lifting cylinder 31 is a single-lever double-acting cylinder, using a solenoid valve with a coil to control the airflow. Two self-locking push-button switches are provided to control the lifting and lowering functions respectively. The lifting cylinder 31 employs an independent control circuit.

[0038] For the motor with lead screw 51, the PLC's pulse output port is connected to the motor driver's pulse input port to control the lead screw's movement distance; the PLC's direction control port is connected to the driver's direction input port to control the lead screw's forward and reverse rotation (determining the object's movement direction). The PLC controls the motor's rotation by outputting pulse and direction signals, driving the lead screw to move the mesh cylinder to the designated position.

[0039] 2. The method of using the chili seedling cultivation device is as follows: Four treatment tanks are set up, each containing a potassium permanganate solution, a copper sulfate solution, clean water, and hot water at 55°C, respectively. The tank containing the hot water at 55°C is equipped with a temperature sensor.

[0040] Chili seeds requiring germination are placed into a mesh cylinder. The control device's screw rotates, moving the mesh cylinder along a guide rail. When the cylinder moves above the treatment cylinder containing potassium permanganate solution, a trigger activates the corresponding position detection component. This component sends a signal to the controller, activating an alarm. Based on this signal, the controller stops the screw motor. Then, an operator operates a lifting cylinder to lower the mesh cylinder into the treatment cylinder containing the potassium permanganate solution, beginning the soaking of the chili seeds. A soaking time warning is set; after 10 minutes, the operator operates the lifting cylinder to raise it.

[0041] The motor of the device continues to move, causing the mesh cylinder to continue moving. When it reaches above the processing cylinder containing copper sulfate solution, the trigger activates the corresponding position detection component. The position detection component transmits a signal to the controller, triggering an alarm. Based on this signal, the controller stops the lead screw motor. The operator then operates the lifting cylinder to lower it, allowing the mesh cylinder to descend into the processing cylinder containing the copper sulfate solution, beginning the soaking of the chili seeds. A soaking time warning is set; after 10 minutes of soaking, the operator operates the lifting cylinder to raise it.

[0042] The motor of the device continues to move, causing the mesh cylinder to continue moving. When it reaches above the treatment cylinder containing clean water, the trigger activates the corresponding position detection component. The position detection component transmits a signal to the controller, triggering an alarm. Based on this signal, the controller stops the lead screw motor. The operator then operates the lifting cylinder to lower it, allowing the mesh cylinder to descend into the treatment cylinder containing clean water. The operator begins washing the chili seeds inside the mesh cylinder, which remain inside. During the washing process, the water in the treatment cylinder can be replaced as needed. After washing, the operator operates the lifting cylinder to raise it.

[0043] Hot water at 55℃ is placed in the fourth processing cylinder. The motor of the device is started again, causing the mesh cylinder to continue moving. When it moves above the processing cylinder containing hot water, the trigger activates the corresponding position detection component. The position detection component transmits a signal to the controller, triggering an alarm. Based on this signal, the controller stops the lead screw motor. The operator operates the lifting cylinder to lower it, allowing the mesh cylinder to descend into the hot water processing cylinder for soaking. During this process, the operator stirs the chili seeds inside the mesh cylinder. Stirring is stopped when the water temperature naturally drops to around 30℃, allowing the seeds to continue soaking for 5-6 hours. After soaking, the mesh cylinder is raised from the processing cylinder to drain the water. The lower mesh cover is then opened, and the seeds are collected on a tray lined with cotton cloth. The seeds fall onto the cotton cloth, and the tray is then placed in a constant temperature chamber at 25-30℃ for germination in the dark.

These descriptions are not intended to limit the present invention to the precise forms disclosed, and it is obvious that many changes and variations can be made based on the above teachings.
