Technical Field
[0001] This utility model relates to the field of seedling equipment technology, specifically to a seedling substrate disinfection device. Background Technology
[0002] During the seedling cultivation process, seeds need to be sown on a substrate. However, there may be some pests and insect eggs in the substrate. In order to ensure the growth of seedlings, the substrate needs to be disinfected.
[0003] Chinese Patent Publication No. CN220778734U discloses a seedling cultivation substrate disinfection device, which includes a box body. Inside the box body, from top to bottom, are arranged a threaded rod, a filter plate, a spray pipe, and a rotating rod. A stirring rake is located at the bottom of the threaded rod. A stirring frame is located on one side of the box body, and a rotating shaft with multiple stirring blades is rotatably mounted inside the stirring frame. After the seedling substrate to be disinfected enters the box body, it is stirred and compacted by the stirring rake, filtered through the filter plate, and then passes onto a baffle. Disinfectant water is then sprayed from nozzles on the spray pipe for disinfection. The substrate falling onto the baffle is further agitated by the stirring rod, facilitating the penetration of disinfectant water into the substrate. This effectively improves the disinfection efficiency of large-scale substrates while reducing the workload of workers. Furthermore, the stirring rake, stirring rod, and spray nozzles work together to enhance the disinfection effect.
[0004] However, the disinfection device disclosed in the above patent still has certain shortcomings in actual use. Since it disinfects the substrate by penetrating disinfectant water into the substrate, this disinfection method carries the risk of chemical residues in the substrate, which is not conducive to the subsequent growth of seeds. Utility Model Content
[0005] The purpose of this invention is to provide a seedling substrate disinfection device to solve the problem mentioned in the background art, which uses disinfectant water to penetrate into the substrate for disinfection. This disinfection method carries the risk of chemical residues in the substrate, which is detrimental to the subsequent growth of seeds.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a seedling substrate disinfection device, comprising a disinfection box, ultraviolet germicidal lamps fixedly installed on the top walls of both inner cavities of the disinfection box, a horizontal plate fixedly installed on one side wall of the disinfection box, an ozone generator installed on the top wall of the horizontal plate, the output end of the ozone generator connected to a conveying box, a gas guide pipe connected between the conveying box and the top inner cavity of the disinfection box, a drive rod rotatably installed between the two side walls of the bottom inner cavity of the disinfection box, a plurality of stirring rods evenly fixedly installed on the surface of the drive rod, a motor whose output end is connected to one end of the drive rod fixed on one side wall of the disinfection box, and a quantitative dispensing mechanism provided at the bottom of the disinfection box.
[0007] Preferably, the quantitative dispensing mechanism includes a feeding box connected to the bottom cavity of the disinfection box, a connecting block is fixedly installed on one side bottom wall of the feeding box, a guide cylinder is fixedly connected to the bottom wall of the connecting block, and a guide hopper is connected between one end of the guide cylinder and the bottom opening of the feeding box.
[0008] Preferably, the quantitative discharge mechanism further includes a rotating rod rotatably installed in the inner cavity of the guide cylinder, one end of the rotating rod penetrating the side wall of the guide cylinder, and a spiral blade fixedly installed on the surface of the rotating rod in the inner cavity of the guide cylinder. Both one end of the drive rod and one end of the rotating rod are fixedly equipped with pulleys, and a belt is sleeved between adjacent pulleys.
[0009] Preferably, one end of the bottom wall of the guide cylinder is connected to a feeding hopper.
[0010] Preferably, a fixing ring is fixedly installed on both sides of the bottom wall of the horizontal plate, and an electric push rod is fixedly installed at the bottom end of the fixing ring. A through hole is opened on one side wall of the top of the feeding box, and a sealing plate adapted to the through hole is provided on one side of the feeding box. The side wall of the sealing plate is fixedly connected to the piston end of the electric push rod.
[0011] Preferably, the bottom of the disinfection box has a semi-circular cross-section, and a feeding cover is installed on the top wall of the middle part of the disinfection box.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] This invention utilizes ultraviolet (UV) germicidal lamps inside the disinfection chamber to destroy the bacterial structure in the substrate, thereby achieving sterilization. An ozone generator is installed outside the chamber, and ozone generated by the generator is introduced into the chamber via a delivery box and air duct for strong oxidative sterilization of the substrate. This combined UV and ozone sterilization method achieves more comprehensive and efficient disinfection while avoiding the risk of chemical residues, thus promoting subsequent seed growth.
[0014] This invention, by setting up a quantitative discharge mechanism, allows the substrate in the disinfection chamber to be sterilized. After the substrate is sterilized, the electric push rod drives the sealing plate to be pulled out of the feeding box through the through hole. This allows the substrate in the disinfection chamber to enter the guide cylinder through the feeding box and the guide hopper. Under the transmission action of the pulley and belt, the motor drives the drive rod to rotate, which in turn drives the rotating rod to rotate. When the rotating rod rotates, it drives the spiral blade to rotate, which in turn causes the spiral blade to discharge the substrate in the guide cylinder quantitatively from the feeding hopper. This avoids blockage during substrate discharge and achieves quantitative discharge. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4This utility model provides a technical solution: a seedling substrate disinfection device, including a disinfection box 1. Ultraviolet germicidal lamps 21 are fixed to the top walls of the left and right inner cavities of the disinfection box 1 by screws. A horizontal plate 3 is welded to the rear side wall of the disinfection box 1. An ozone generator 4 is installed on the top wall of the horizontal plate 3. A conveying box 5 is connected to the output end of the ozone generator 4. A gas guide pipe 6 connects the conveying box 5 and the top inner cavity of the disinfection box 1, the purpose of which is to allow the ozone generated by the ozone generator 4 to enter the disinfection box 1 through the conveying box 5 and the gas guide pipe 6 to disinfect the substrate. A drive rod 19 is rotatably mounted between the left and right side walls of the bottom inner cavity of the disinfection box 1 via bearings. The left end of the drive rod 19 penetrates the left side wall of the disinfection box 1. Multiple stirring rods 20 are evenly welded to the surface of the drive rod 19. The stirring rods 20 are all located in the inner cavity of the disinfection box 1, and their function is to agitate and stir the substrate in the disinfection box 1, so that the substrate can be fully irradiated by ultraviolet light and come into contact with ozone. The right side wall of the disinfection box 1 is fixed with a motor 7 whose output end is connected to the right end of the drive rod 19 via a coupling. The bottom of the disinfection box 1 is equipped with a quantitative discharge mechanism for discharging the substrate quantitatively after disinfection.
[0022] The quantitative dispensing mechanism includes a feeding box 13 connected to the bottom cavity of the disinfection box 1. A connecting block 23 is welded to the right bottom wall of the feeding box 13, and a guide cylinder 11 is welded to the bottom wall of the connecting block 23. A guide hopper 22 is connected between the left end of the guide cylinder 11 and the bottom opening of the feeding box 13. The purpose of this is to allow the substrate in the disinfection box 1 to enter the guide cylinder 11 through the feeding box 13 and the guide hopper 22. The quantitative dispensing mechanism also includes a rotating rod 16 rotatably mounted in the cavity of the guide cylinder 11 via a bearing. The left end of the rotating rod 16 penetrates the left side wall of the guide cylinder 11. A spiral blade 14 is welded to the surface of the rotating rod 16 in the cavity of the guide cylinder 11. Pulleys 17 are welded to the left end of the drive rod 19 and the left end of the rotating rod 16. A belt 18 is sleeved between adjacent pulleys 17. The purpose of this is to allow the rotating rod 16 to rotate together when the drive rod 19 rotates. The bottom wall of the guide cylinder 11 is connected to the discharge hopper 12 for discharging material. Fixing rings 8 are welded to the bottom walls of both sides of the horizontal plate 3. An electric push rod 9 is welded to the bottom end of the fixing rings 8. A through hole 15 is opened on the rear side wall of the top of the discharge box 13. A sealing plate 10, adapted to the through hole 15, is provided on the rear side of the discharge box 13. The purpose of this is to allow the sealing plate 10 to extend into the discharge box 13 through the through hole 15, thereby preventing the substrate in the disinfection box 1 from falling into the discharge box 13. The rear side wall of the sealing plate 10 is welded to the piston end of the electric push rod 9, so that the electric push rod 9 can move the sealing plate 10. The bottom of the disinfection box 1 has a semi-circular cross-section. A feeding cover 2 is installed on the top wall of the middle part of the disinfection box 1 for adding the substrate to be disinfected into the disinfection box 1.
[0023] In use, first open the feeding cover 2 and add the substrate to be disinfected into the disinfection box 1. Then close the feeding cover 2, turn on the motor 7, the ultraviolet germicidal lamp 21, and start the ozone generator 4. The ultraviolet germicidal lamp 21 is installed inside the disinfection box 1. Ultraviolet light destroys the body structure of bacteria in the substrate, thus achieving sterilization. The ozone generator 4 is installed outside the disinfection box 1. The ozone generated by the ozone generator 4 is introduced into the disinfection box 1 through the conveying box 5 and the air duct 6, providing strong oxidative sterilization of the substrate. This combined ultraviolet and ozone sterilization method achieves more comprehensive and efficient disinfection, avoiding the risk of chemical residues and promoting subsequent seed growth. As the motor 7 drives the drive rod 19 to rotate, the drive rod... 19 rotates and drives the stirring rod 20 to agitate the substrate in the disinfection box 1, so that it is fully exposed to ultraviolet light and ozone. After the substrate in the disinfection box 1 is sterilized, the electric push rod 9 drives the sealing plate 10 to be pulled out from the feeding box 13 through the through hole 15. The substrate in the disinfection box 1 then enters the feeding cylinder 11 through the feeding box 13 and the guide hopper 22. Under the transmission action of the pulley 17 and the belt 18, the motor 7 drives the drive rod 19 to rotate, which in turn drives the rotating rod 16 to rotate. When the rotating rod 16 rotates, it drives the spiral blade 14 to rotate, which in turn causes the spiral blade 14 to discharge the substrate in the feeding cylinder 11 quantitatively from the feeding hopper 12, thereby avoiding blockage during substrate discharge and achieving quantitative discharge.
