Description

Technical Field

[0001] This utility model relates to the field of cultivation substrate production technology, specifically to an improved dragon fruit cultivation substrate. Background Technology

[0002] To ensure the safe growth of dragon fruit seedlings, a cultivation substrate is typically used instead of the soil required for seedling growth. The substrate provides the necessary support, water retention, fertilizer retention, and aeration. The selection and preparation of the cultivation substrate have a significant impact on crop growth and yield. During substrate preparation, sterilization is necessary to kill or remove any potential pathogens, insect eggs, and other harmful organisms. Common sterilization methods include high-temperature steam sterilization and chemical disinfection.

[0003] A cultivation substrate disinfection device disclosed in patent application CN217853917U includes a support frame, a bed board fixed on the support frame, at least one steam pipe longitudinally arranged on the bed board, several through holes spaced apart on the steam pipe, an inner mesh pipe installed inside the steam pipe, and the steam pipe connected to a steam source. High-temperature steam is delivered into the cultivation substrate using the steam pipe with several through holes and the inner mesh pipe. The steam pipe is supported on the bed board by U-shaped frames stacked opposite each other, allowing for comprehensive high-temperature disinfection, sterilization, and insect control of the cultivation substrate around the steam pipe. This not only provides excellent disinfection but also kills insect eggs and bacteria without leaving any drug residue. The mesh pipe inside the steam pipe effectively prevents the cultivation substrate from entering and causing blockages. Finally, a movable cover allows the high-temperature disinfection, sterilization, and insect control to continue for the required time under the cover, greatly improving the disinfection, sterilization, and insect control effects.

[0004] However, the following problems still exist:

[0005] When the above-mentioned high-temperature sterilization and disinfection device disinfects the cultivation substrate, it is necessary to manually pile the cultivation substrate on the bed board, which has low work efficiency and makes workers prone to fatigue. In addition, the manual stacking is prone to unevenness, which affects the sterilization efficiency.

[0006] Therefore, we propose an improved dragon fruit cultivation substrate to solve the above problems. Summary of the Invention

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0025] Please see Figure 1-6 An improved dragon fruit cultivation substrate includes a support frame 1 and a sterilization chamber 2. The sterilization chamber 2 is characterized by having an air jet plate 4 fixedly connected to its bottom surface, an air jet port 5 on the inner wall of the air jet plate 4, an air inlet pipe 6 connected to the bottom surface of the air jet plate 4, a drive motor 7 on one side of the sterilization chamber 2, a reciprocating screw 8 fixedly connected to the output end of the drive motor 7, and the other end of the reciprocating screw 8 rotatably connected to the side wall of the sterilization chamber 2. A reciprocating sleeve 9 is threadedly connected to the outer wall of the reciprocating screw 8, and a feeding device is connected to the side wall of the reciprocating sleeve 9. A heat preservation device is connected to one side of the feeding device.

[0026] As can be seen from the above structure, by setting up a sterilization chamber 2, a jet plate 4, an air inlet pipe 6, a drive motor 7, a reciprocating screw 8, a reciprocating sleeve 9, and a feeding device, when high-temperature sterilization of the cultivation substrate is required, the cultivation substrate is first placed into the feeding device, and then the drive motor 7 is started, so that the feeding device evenly spreads the cultivation substrate in the sterilization chamber 2. The heat preservation device can ensure the airtightness of the sterilization chamber 2. Then, high-temperature gas is sprayed out from the jet nozzle 5 of the jet plate 4 through the air inlet pipe 6 to sterilize the cultivation substrate at high temperature. After the sterilization of the cultivation substrate is completed, the drive motor 7 is started, so that the feeding device pushes the high-temperature sterilized cultivation substrate out of the sterilization chamber 2. At the same time, the cultivation substrate that has not been sterilized in the feeding device will be evenly spread in the sterilization chamber 2, which is convenient for the next sterilization. It is simple, practical and improves work efficiency.

[0027] Furthermore, the feeding device includes a storage bin 10 fixedly connected to the side wall of the reciprocating sleeve 9, and the bottom surface of the storage bin 10 is slidably connected to the side wall of the sterilization bin 2. An inclined pusher plate 11 is slidably connected to the side wall of the jet plate 4, and the upper surface of the inclined pusher plate 11 is fixedly connected to the bottom surface of the storage bin 10. Inclined discharge ports 12 are provided on the bottom surfaces of the storage bins 10 located on both sides of the inclined pusher plate 11, and the side walls of the inclined discharge ports 12 are provided with sealing mechanisms. Two discharge ports 16 are provided on the bottom surface of the sterilization bin 2, and strip-shaped grooves are provided on the side walls of the discharge ports 16. A discharge spring 17 is fixedly connected to the inner wall of the strip-shaped groove, and a T-shaped sealing plate 18 is fixedly connected to the other end of the discharge spring 17. The other end of the T-shaped sealing plate 18 penetrates the side wall of the strip-shaped groove and connects to the side wall of the strip-shaped groove. The wall is slidably connected, and the side wall of the T-shaped sealing plate 18 located on one side of the jet plate 4 abuts against the side wall of the discharge port 16. The side wall of the discharge port 16 located on one side of the jet plate 4 is fixedly connected to the inclined discharge plate 19, and a material box 20 is provided below the inclined discharge plate 19. By setting up the reciprocating sleeve 9, the storage bin 10, the inclined push plate 11, the inclined discharge port 12, the T-shaped sealing plate 18, the strip chute, the discharge spring 17 and the material box 20 for high-temperature sterilization of the cultivation substrate, the cultivation substrate is first put into the storage bin 10, and then the drive motor 7 is started to drive the reciprocating sleeve 9 to reciprocate. When the reciprocating sleeve 9 moves to the left, it will drive the storage bin 10 to move to the left, and at the same time open the sealing plate in the inclined discharge port 12 on the right side of the inclined push plate 11. The blocking mechanism allows the cultivation substrate to slide into the sterilization chamber 2 from the right-side inclined discharge port 12 when the storage hopper 10 moves to the left, ensuring even distribution without unevenness. The discharge spring 17 pushes the T-shaped sealing plate 18 against the side wall of the discharge port 16, sealing the cultivation substrate in the sterilization chamber 2 and preventing it from sliding out of the discharge port 16. This ensures the airtightness of the sterilization chamber 2 and improves sterilization efficiency. When the storage hopper 10 moves to the left side of the discharge port 16, the drive motor 7 stops, and the blocking mechanism closes to prevent further sliding of the cultivation substrate. High-temperature sterilization of the cultivation substrate can then begin. When the sterilization chamber 2 completes the sterilization of the cultivation substrate, the start-up mechanism is activated. The drive motor 7 drives the storage bin 10 to slide to the right, simultaneously opening the sealing mechanism on the left. The inclined pusher plate 11, fixedly connected to the bottom of the storage bin 10, pushes the sterilized cultivation substrate on the right, causing the cultivation substrate to push the T-shaped sealing plate 18 to squeeze the discharge spring 17 backward. The cultivation substrate then slides from the discharge port 16 on the right into the material box 20, making it convenient for workers to collect the cultivation substrate. When the inclined pusher plate 11 pushes the cultivation substrate out of the sterilization bin 2 from the discharge port 16 on the right, the sterilization bin 2 on the left side of the inclined pusher plate 11 will be filled with the cultivation substrate that has slid down from the storage bin 10, allowing the sterilization of the cultivation substrate to continue. This process is efficient, convenient, and ensures that the cultivation substrate is spread more evenly in the sterilization bin 2, improving sterilization efficiency.

[0028] Furthermore, the sealing mechanism includes a chute 21 formed on the side wall of the inclined discharge port 12, and a sealing plate 22 is slidably connected to the side wall of the chute 21. The other end of the sealing plate 22 passes through the side wall of the chute 21 and extends out of the chute 21. A U-shaped groove is formed on the upper surface of the sealing plate 22, and an inclined limiting groove 23 is formed on the bottom surface of the sealing plate 22. A limiting groove 24 is formed on the bottom surface of the chute 21 located on one side of the U-shaped groove. A limiting spring 25 is fixedly connected to the bottom surface of the limiting groove 24, and a limiting inclined block 26 is fixedly connected to the other end of the limiting spring 25. By setting the chute 21, sealing plate 22, U-shaped groove, inclined limiting groove 23, limiting groove 24, limiting spring 25, and limiting inclined block 26 to work together, when the sealing mechanism is opened, the U-shaped groove is pulled to drive the chute 21. The sealing plate 22 slides along the chute 21, allowing the cultivation substrate in the storage bin 10 to slide into the sterilization bin 2 through the inclined discharge port 12. When the inclined limiting groove 23 moves above the limiting inclined block 26, the limiting spring 25 pushes the limiting inclined block 26 to slide and connect with the inclined limiting groove 23, preventing the sealing plate 22 from being pulled out of the chute 21 and causing the cultivation substrate in the storage bin 10 to leak from the chute 21. When it is necessary to close the sealing mechanism, the sealing plate 22 is pushed. At this time, the inclined limiting groove 23 on the bottom surface of the sealing plate 22 pushes the inclined surface of the limiting inclined block 26, causing the limiting inclined block 26 to slide down along the limiting groove 24 and then slide into the chute 21 to seal the inclined discharge port 12, preventing the cultivation substrate in the storage bin 10 from continuing to slide down.

[0029] Furthermore, the heat preservation device includes cloth chambers 13 located at both ends of the sterilization chamber 2, with cloth shafts 14 fixedly connected to the inner walls of the cloth chambers 13, and heat preservation cloth 15 fixedly connected to the side walls of the cloth shafts 14. The other end of the heat preservation cloth 15 is fixedly connected to the side wall of the storage chamber 10. Through the coordinated use of the cloth chambers 13, cloth shafts 14, and heat preservation cloth 15, when the storage chamber 10 moves to the left, the heat preservation cloth 15 fixedly connected to the right side wall of the storage chamber 10 will be pulled out of the cloth chamber 13, thereby covering the upper surface of the sterilization chamber 2 to ensure the sterilization temperature of the sterilization chamber 2. The heat preservation cloth 15 located on the right side of the sterilization chamber 2 will be pushed into the cloth chamber 13 on the left side by the storage chamber 10, and will not be randomly piled up.

[0030] Furthermore, a roller 3 is rotatably connected to the inner wall of the fabric compartment 13 located below the insulation cloth 15, and the side wall of the roller 3 is in rolling connection with the bottom surface of the insulation cloth 15. The design of the roller 3 prevents the insulation cloth 15 from being damaged by friction with the side wall of the fabric compartment 13 when it slides out of the fabric compartment 13, thereby affecting the insulation effect of the insulation cloth 15.

[0031] Furthermore, a roller groove 27 is provided on the upper surface of the sterilization chamber 2 located below the storage chamber 10, and multiple sets of roller shafts 28 are fixedly connected to the bottom surface of the storage chamber 10. Rollers 29 are rotatably sleeved on the side wall of the roller shafts 28, and the bottom surface of the rollers 29 is in rolling connection with the bottom surface of the roller groove 27. By setting the roller groove 27, roller shafts 28 and rollers 29 to work together, the friction force generated by the friction between the storage chamber 10 and the side wall of the sterilization chamber 2 when the storage chamber 10 moves is reduced, which facilitates the movement of the storage chamber 10.
