Description

Technical Field

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

[0002] Chili seedling raising devices are facilities or equipment specifically designed for cultivating chili seedlings. In the seedling raising stage of chili cultivation, the precise filling of the seedling substrate into the filling trough of the seedling tray is the foundation for ensuring seedling quality. The uniformity of filling directly affects the germination rate of chili seeds and the uniformity of seedling growth.

[0003] Currently, most pepper seedling raising devices rely on manual operation or a simple tilting filling structure for substrate filling. When filling manually, operators use a scraper to manually scrape the substrate into the filling groove of the seedling tray. In batch operations, this is labor-intensive and inefficient. Utility Model Content

[0004] Based on the aforementioned technical problems of traditional chili seedling raising devices relying on manual labor or simple tilting structures for substrate filling, which result in high labor intensity and low efficiency, this utility model proposes a seedling raising device for chili cultivation.

[0005] This utility model discloses a seedling raising device for chili pepper cultivation, comprising a mounting frame and a second stepper motor. The mounting frame has discharge holes on both sides and storage boxes fixedly connected to both sides. Slide grooves are formed on both sides of the inner wall of the mounting frame. Two support plates are fixedly connected to both sides of the mounting frame. Slide rods are provided in the slide grooves, with both ends of the slide rods fixedly connected to the support plates. Support plates are fixedly connected to the tops of the two storage boxes. A ball screw is rotatably connected between the two support plates. A scraper is fixedly connected to the outer wall of the ball nut on the ball screw. The end of the slide rod passes through the scraper and is slidably connected to it. The second stepper motor is fixedly connected to the outer wall of the mounting frame, and its output end is fixedly connected to the end of the ball screw.

[0006] Preferably, the support plate has an L-shaped structure, and the two ends of the slide rod extend to the outer wall of the mounting frame and are located above the storage box.

[0007] Preferably, the mounting frame has inlet and outlet holes on both sides, and a conveyor frame is fixedly connected to each inlet and outlet hole. Conveyor rollers are rotatably connected to the inner wall of each conveyor frame, and a conveyor belt is sleeved on the outer wall of each of the two conveyor rollers.

[0008] Preferably, a first stepper motor is fixedly connected to one side wall of the conveyor frame, and the output end of the first stepper motor is fixedly connected to the conveyor roller.

[0009] Preferably, the outer wall of the conveyor belt is fixedly connected with multiple spacer strips at equal intervals, and a seedling tray is placed between two adjacent spacer strips.

[0010] Preferably, two fixed plates are fixedly connected to the top of one side of the conveyor frame, a rotating sleeve is rotatably connected between the two fixed plates, and multiple pressure rods are fixedly connected to the outer wall of the rotating sleeve.

[0011] Preferably, a third stepper motor is fixedly connected to the outer wall of the conveyor frame, and the output end of the third stepper motor is fixedly connected to the rotating sleeve.

[0012] The beneficial effects of this utility model, achieved through the above technical solution, are as follows:

[0013] 1. The second stepper motor drives the ball screw, which moves the scraper along the slide bar to automatically scrape in the substrate, replacing manual operation and fundamentally reducing labor intensity. The horizontal movement of the scraper completes the filling of the seedling tray. Combined with the continuous conveyor belt, it forms an assembly line operation, reducing labor intensity and improving batch filling efficiency, thus solving the problem of low efficiency of manual filling.

[0014] 2. The L-shaped support plate provides stable support for the slide bar, which extends above the storage box, ensuring that the scraper's movement range covers the entire seedling tray. At the same time, it facilitates the recovery of excess substrate through the discharge hole, improving substrate utilization.

[0015] 3. The spacers are evenly distributed on the conveyor belt to separate and position the seedling trays, prevent them from shifting during transport, ensure precise alignment between the seedling trays and the scraper when filling the substrate, and improve filling accuracy.

[0016] 4. The third stepper motor drives the rotating sleeve to rotate, which in turn drives the pressure rod to rotate. The pressure rod gently presses the substrate on the surface of the seedling tray, pressing a groove in each seedling tray hole, which makes it easier to place the pepper seeds in the groove later.

[0022] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] In this utility model, unless otherwise explicitly specified and limited, the term "fixed connection" should be interpreted broadly. For example, "fixed connection" can mean fixed installation, detachable connection, or integral connection; it can mean mechanical connection or electrical connection; it can mean direct connection. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0024] like Figures 1-3 As shown, a seedling raising device for chili pepper cultivation includes a mounting frame 1 and a second stepper motor 14. The mounting frame 1 has discharge holes 3 on both sides, and storage boxes 10 are fixedly connected to both sides of the mounting frame 1. Slide grooves 4 are provided on both sides of the inner wall of the mounting frame 1. Two support plates 11 are fixedly connected to both sides of the mounting frame 1. Slide rods 12 are provided in each slide groove 4, with both ends of the slide rods 12 fixedly connected to the support plates 11. Support plates 15 are fixedly connected to the tops of the two storage boxes 10. A ball screw 13 is rotatably connected between the two support plates 15. A scraper 20 is fixedly connected to the outer wall of the ball nut on the ball screw 13. The end of the slide rod 12 passes through the scraper 20 and is slidably connected to it. The second stepper motor 14 is fixedly connected to the outer wall of the mounting frame 1, and the output end of the second stepper motor 14 is fixedly connected to the end of the ball screw 13.

[0025] The slide bar 12 guides the scraper 20.

[0026] The second stepper motor 14 drives the ball screw 13 to move the scraper 20 along the slide bar 12, thereby realizing the automatic filling of the substrate, replacing manual scraper operation, reducing the labor intensity during batch operations, improving filling efficiency, and solving the problem of low efficiency of manual filling.

[0027] In this embodiment, as Figure 3 As shown, the support plate 11 has an L-shaped structure, and the two ends of the slide rod 12 extend to the outer wall of the mounting frame 1 and are located above the storage box 10.

[0028] The L-shaped support plate 11 provides stable support for the slide bar 12, which extends above the storage box 10, ensuring that the movement range of the scraper 20 covers the entire seedling tray, while facilitating the recovery of excess substrate through the discharge hole 3, thereby improving substrate utilization.

[0029] In this embodiment, as Figure 1 As shown, the mounting frame 1 has inlet and outlet holes 2 on both sides, and a conveyor frame 5 is fixedly connected to each inlet and outlet hole 2. The inner wall of the conveyor frame 5 is rotatably connected to a conveyor roller 6, and a conveyor belt 8 is sleeved on the outer wall of the two conveyor rollers 6.

[0030] One side of the conveyor frame 5 is fixedly connected to the first stepper motor 7, and the output end of the first stepper motor 7 is fixedly connected to the conveyor roller 6.

[0031] The seedling trays are continuously conveyed under the drive of the first step motor 7, and together with the scraper 20, they form an automated filling production line.

[0032] In this embodiment, as Figure 1 As shown, multiple spacer strips 9 are fixedly connected at equal intervals on the outer wall of the conveyor belt 8, and seedling trays are placed between two adjacent spacer strips 9.

[0033] The spacer strips 9 are evenly distributed on the conveyor belt 8 to separate and position the seedling trays, prevent the seedling trays from shifting during the conveying process, and ensure that the seedling trays and scraper 20 are accurately aligned when the substrate is filled, thereby improving the filling accuracy.

[0034] In this embodiment, as Figure 1 and Figure 4 As shown, two fixed plates 17 are fixedly connected to the top of the conveyor frame 5 on one side, and a rotating sleeve 18 is rotatably connected between the two fixed plates 17. Multiple pressure rods 19 are fixedly connected to the outer wall of the rotating sleeve 18.

[0035] A third stepper motor 16 is fixedly connected to the outer wall of the conveyor frame 5, and the output end of the third stepper motor 16 is fixedly connected to the rotating sleeve 18.

[0036] The third stepper motor 16 drives the rotating sleeve 18 to rotate, which in turn drives the pressure rod 19 to rotate. The pressure rod 19 lightly presses the substrate on the surface of the seedling tray, pressing a groove in each seedling tray hole, which makes it easier to place the pepper seeds in the groove later.

[0037] To achieve automated and coordinated synchronous operation of seedling tray conveying, substrate filling, and grooving, this device can be controlled by a control unit. The control unit is electrically connected to the first stepper motor 7, the second stepper motor 14, and the third stepper motor 16 via signal lines. Simultaneously, the control unit receives signals from sensors installed at key positions on the device to detect the position status of the seedling trays. A first position sensor, such as a photoelectric sensor, can be installed at the inlet below the scraper 20 on the mounting frame 1 to detect whether the seedling tray has reached the filling position. A second position sensor can be installed at the outlet of the mounting frame 1 to detect whether the seedling tray has left the filling position or reached the grooving position. A seedling tray positioning sensor can be installed at the beginning of the conveyor belt 8 or near the spacer 9 to detect whether a seedling tray is placed on the conveyor belt.

[0038] The control unit coordinates the start, stop, speed, and direction of the three stepper motors according to the preset program logic and the received sensor signals, ensuring that each action is performed in sequence and in coordination, as follows:

[0039] When the seedling tray positioning sensor detects that the seedling tray has been placed, the control unit starts the first step motor 7, which drives the conveyor belt 8 to transport the seedling tray into the mounting frame 1. When the first position sensor detects that the seedling tray has completely reached the substrate filling position, that is, directly below the scraper 20, the control unit sends a stop signal to the first step motor 7, so that the conveyor belt 8 stops precisely, ensuring that the seedling tray stays stably in the filling position.

[0040] After the conveyor belt 8 stops, the control unit immediately starts the second stepper motor 14. The second stepper motor 14 drives the ball screw 13 to rotate, causing the scraper 20 to complete one reciprocating stroke along the slide bar 12. During the movement of the scraper 20, the substrate above the storage box 10 or the pre-sprinkled substrate is evenly scraped into the filling groove of the seedling tray, and the excess substrate is recycled back to the storage box 10 through the discharge hole 3.

[0041] After the scraper 20 completes the set filling action, the control unit restarts the first stepper motor 7, driving the conveyor belt 8 to transport the seedling tray filled with substrate to the outside of the mounting frame 1. At the same time, the control unit stops the second stepper motor 14.

[0042] As the seedling tray continues to move on the conveyor belt 8, until the second position sensor detects that it has reached the pressing position, the control unit sends a signal to the first stepper motor 7 to stop it, and at the same time starts the third stepper motor 16.

[0043] The third stepper motor 16 drives the rotating sleeve 18 to rotate at a certain angle, which in turn drives the pressure rod 19 to rotate and press down, gently pressing the substrate on the surface of the seedling tray below, forming a groove in each hole.

[0044] After the pressure bar 19 completes the set pressing action, the control unit stops the third stepper motor 16 and restarts the first stepper motor 7 to completely transport the seedling tray that has completed pressing out of the device. At this time, the conveyor belt 8 can continue to run and wait for the next seedling tray to enter.

[0045] It is worth noting that the connection and control between the "control unit" and the first stepper motor 7, the second stepper motor 14 and the third stepper motor 16 are existing technologies, and such connection and control methods are not the actual technical problems that this application needs to solve, so they will not be elaborated on here.

[0046] When in use, first place the seedling tray between two adjacent spacers 9 on the conveyor belt 8. The first step motor 7 drives the conveyor roller 6 to rotate, which drives the conveyor belt 8 to transport the seedling tray through the inlet and outlet holes 2 into the mounting frame 1.

[0047] When the seedling tray reaches the substrate filling position, conveyor belt 8 stops running.

[0048] The seedling substrate is evenly sprinkled on the seedling tray inside the mounting frame 1. The second stepper motor 14 drives the ball screw 13 to rotate, so that the ball nut drives the scraper 20 to move horizontally along the slide bar 12. During the movement, the scraper 20 evenly scrapes the substrate into the filling groove of the seedling tray. The excess substrate is recycled into the storage box 10 through the discharge hole 3.

[0049] After filling is complete, the conveyor belt 8 continues to run, transporting the seedling trays to the outside of the mounting frame 1. During the transport process, the third stepper motor 16 drives the rotating sleeve 18 to rotate, which in turn drives the pressure rod 19 to rotate. The pressure rod 19 lightly presses the substrate on the surface of the seedling tray, pressing a groove in each seedling tray hole.

[0050] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
