Description

Technical Field

[0001] This utility model belongs to the field of seedling substrate disinfection technology, and in particular, a seedling substrate disinfection and sterilization device. Background Technology

[0002] The seedling substrate is made from peat moss produced in the primeval forests of Changbai Mountain in Northeast China, vermiculite from Lingshou County, and other additives in a certain proportion. This prevents harmful substances such as pathogens and insect eggs in the seedling substrate from reducing crop yield and quality. The seedling substrate must be disinfected before planting. Currently, steam sterilization is used for sterilization. However, when the current sterilization device sterilizes the seedling substrate, it spreads the substrate out for sterilization, causing the substrate inside the device to rotate for sterilization. This results in an unsatisfactory sterilization effect in the center of the seedling substrate, thus reducing the efficiency and effectiveness of the seedling substrate sterilization.

[0003] A Chinese patent (authorization announcement number CN221770906U) discloses a steam sterilization device for a substrate, which "includes a steam oven, and a number of steaming cages are arranged sequentially from bottom to top on the top of the steam oven. The top of the uppermost steaming cage is connected to a sealing cover that seals it. The sealing cover and the steaming cage are detachably connected, and two adjacent steaming cages are connected by a connecting component."

[0004] It is evident that the cited patent document has the problem of difficulty in disinfecting the seedling substrate in the central part of the plant. Utility Model Content

[0005] The purpose of this invention is to provide a seedling substrate disinfection and sterilization device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a seedling substrate disinfection and sterilization device, comprising a disinfection box, a rotating rod rotatably connected to the inner wall of the disinfection box via a pin shaft, two fixed rings fixedly sleeved on the periphery of the rotating rod, connecting rods connected to the periphery of each of the two fixed rings, and a turning block for turning the seedling substrate connected to the bottom end of the two connecting rods, a rack provided in the inner cavity of the disinfection box above the rotating rod, a gear meshing with the rack fixedly sleeved on the periphery of the rotating rod, a slide rail installed on the inner wall of the disinfection box, a slider slidably sleeved on the periphery of the slide rail installed on one side of the rack, and a drive component for driving the rack to move laterally installed through one side of the disinfection box.

[0007] Preferably, the drive assembly includes a drive motor, a turntable, a hinge rod, and a hinge seat, with the drive motor mounted on one side of the disinfection box.

[0008] Preferably, the output end of the drive motor extends into the inner cavity of the disinfection box, and one side of the turntable is connected and fixed to the output end of the drive motor.

[0009] Preferably, the hinge rod is rotatably connected to an eccentric position on one side of the turntable via a pin, the hinge seat is hinged to one end of the hinge rod, and one side of the hinge seat is mounted on one side of the rack.

[0010] Preferably, the top surface of the disinfection box is symmetrically connected to two pressure relief boxes, and the inner top surface of each of the two pressure relief boxes is connected to a spring.

[0011] Preferably, the free ends of both springs are connected to blocking blocks for sealing the gas, and both sides of the two pressure relief boxes are provided with pressure relief holes for releasing gas.

[0012] Preferably, one side of the disinfection box is connected to a steam pipe for conveying high-temperature steam to disinfect and sterilize the seedling substrate, and a steam generator is connected to the free end of the steam pipe.

[0013] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0014] This seedling substrate disinfection and sterilization device achieves the reciprocating rotation of gears by moving the rack laterally, which in turn drives the turning block to rotate around the rotating rod as the axis, thereby turning the seedling substrate. Compared with existing devices for disinfecting and sterilizing seedling substrate, this device can turn the seedling substrate, which can improve the disinfection effect of the seedling substrate in the inner center, thus improving the efficiency of disinfection and sterilization.

[0015] By setting up the drive components, the rack can be driven to make lateral reciprocating motion, which makes it easy for the turning block to rotate back and forth and turn the seedling substrate.

[0016] With the addition of pressure relief holes and plugs, the gas can be released to relieve pressure when the steam pressure inside the sterilization chamber is too high, thus preventing damage to the sterilization chamber caused by excessively high pressure. Attached Figure Description

[0024] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0025] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0026] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0027] like Figures 1 to 4 The device shown is a seedling substrate disinfection and sterilization device, including a disinfection box 1. The top surface of the disinfection box 1 is connected to an inlet pipe 18 for adding seedling substrate. The inner cavity of the inlet pipe 18 is filled with a sealing plug 19. Personnel can add seedling substrate into the disinfection box 1 through the inlet pipe 18 and seal the inlet pipe 18 through the sealing plug 19. The bottom surface of the disinfection box 1 is connected to a drain pipe with a solenoid valve. By opening the solenoid valve, the disinfected and sterilized seedling substrate can be discharged through the drain pipe.

[0028] One side of the disinfection box 1 is connected to a steam pipe 20 for conveying high-temperature steam to disinfect and sterilize the seedling substrate. The free end of the steam pipe 20 is connected to a steam generator. After the seedling substrate that needs to be disinfected and sterilized is added into the disinfection box 1, the high-temperature steam is conveyed to the steam pipe 20 through the external steam generator, and then conveyed into the disinfection box 1 through the steam pipe 20 to disinfect the seedling substrate with steam.

[0029] The inner wall of the disinfection box 1 is rotatably connected to a rotating rod 2 via a pin. Two fixing rings 3 are fixedly sleeved around the circumference of the rotating rod 2. Each of the two fixing rings 3 is connected to a connecting rod 4. The bottom ends of the two connecting rods 4 are connected to a turning block 5 for turning the seedling substrate. During steam disinfection, the operator rotates the rotating rod 2 in both directions, causing the rotating rod 2 to drive the two fixing rings 3 to rotate back and forth, thereby driving the two connecting rods 4 to rotate back and forth. This allows the turning block 5 to rotate back and forth around the rotating rod 2 as the axis, thus turning the seedling substrate and allowing the high-temperature steam to effectively act on the seedling substrate located in the center of the box.

[0030] A rack 6 is located above the rotating rod 2 within the inner cavity of the disinfection box 1. Gears 7, meshing with the rack 6, are fixedly sleeved around the periphery of the rotating rod 2. A drive assembly for driving the rack 6 to move laterally is installed through one side of the disinfection box 1. The drive assembly includes a drive motor 10, a turntable 11, a hinge rod 12, and a hinge seat 13. The drive motor 10 is mounted on one side of the disinfection box 1, and its output end extends into the inner cavity of the disinfection box 1. One side of the turntable 11 is fixedly connected to the output end of the drive motor 10. The hinge rod 12 is rotatably connected to the eccentric position of one side of the turntable 11 via a pin. The hinge seat 13 is hinged to one end of the hinge rod 12, and one side of the hinge seat 13 is mounted on one side of the rack 6. By turning on the drive motor 10, the turntable 11 can be rotated, thereby causing the hinge rod 12 to rotate. The hinge rod 12 is rotatably connected to the eccentric position of one side of the turntable 11 via a pin, and one end of the hinge rod 12 is hinged to the hinge seat 13. Therefore, when the turntable 11 drives the hinge rod 12 to rotate, the hinge rod 12 will drive the hinge seat 13 to move laterally back and forth, thereby driving the rack 6 to move laterally back and forth. Since the rack 6 and the gear 7 mesh with each other, the rack 6 will drive the gear 7 to rotate back and forth when it moves laterally back and forth, thereby driving the rotating rod 2 to rotate back and forth. Then, through the fixed ring 3 and the connecting rod 4, the turning block 5 will rotate back and forth, thereby turning the seedling substrate. This allows the high-temperature steam to act well on the seedling substrate in the inner center, avoiding the situation where the disinfection effect in the inner center of the seedling substrate is not ideal during steam disinfection, and improving the efficiency and effect of disinfection and sterilization of the seedling substrate.

[0031] The inner wall of the disinfection box 1 is equipped with a slide rail 8, and a slider 9 is installed on one side of the rack 6 and slidably sleeved around the slide rail 8. When the rack 6 moves laterally back and forth, it will drive the slider 9 to move around the slide rail 8, so that the slide rail 8 and the slider 9 can limit the movement trajectory of the rack 6 and prevent deviation.

[0032] The top surface of the disinfection box 1 is symmetrically connected to two pressure relief boxes 14. The inner top surface of each pressure relief box 14 is connected to a spring 15. The free end of each spring 15 is connected to a blocking block 16 for blocking gas. Both sides of the two pressure relief boxes 14 are provided with pressure relief holes 17 for venting gas. When the steam pressure inside the disinfection box 1 is too high, the excessive pressure will push the blocking block 16 upward, causing the blocking block 16 to move upward and squeeze the spring 15. The spring 15 will deform after being squeezed, buffering the force and achieving a damping effect. When the blocking block 16 moves upward above the pressure relief hole 17, the gas inside the disinfection box 1 can be discharged from the pressure relief hole 17, preventing the excessively high gas pressure inside the disinfection box 1 from damaging the disinfection box 1.

[0033] Working principle:

[0034] This seedling substrate disinfection and sterilization device adds the seedling substrate to be disinfected into the disinfection chamber 1 through the feed pipe 18. Then, a high-temperature steam generator, connected externally, delivers steam to the disinfection chamber 1 through the steam pipe 20 for steam disinfection of the seedling substrate. At this time, the drive motor 10 is turned on, which drives the hinge rod 12 to rotate via the turntable 11. Since the hinge rod 12 is rotatably connected to the turntable 11 at an eccentric position on one side via a pin, and one end of the hinge rod 12 is hinged to the hinge seat 13, when the turntable 11 drives the hinge rod 12 to rotate, the hinge rod 12 will drive the hinge... The seat 13 moves laterally back and forth, thereby driving the rack 6 to move laterally back and forth. Since the rack 6 meshes with the gear 7, the rack 6 will drive the gear 7 to rotate back and forth, which in turn drives the fixed ring 3 and the connecting rod 4 to rotate back and forth through the rotating rod 2. This allows the flipping block 5 to rotate back and forth around the rotating rod 2 as the axis, thereby flipping the seedling substrate. This allows the high-temperature steam to act effectively on the seedling substrate in the inner center, avoiding the situation where the disinfection effect in the inner center of the seedling substrate is not ideal during steam disinfection, and improving the efficiency and effect of disinfection and sterilization of the seedling substrate.
