[0001] This utility model relates to the field of atmospheric pressure sterilizer technology, specifically to a culture medium feeding mechanism and an atmospheric pressure sterilization device. Background Technology

[0002] In the cultivation of morel mushrooms, mushroom substrate is required. The substrate is mainly composed of crop straw powder (such as corn stalks), sawdust, cotton hulls, bran humus, etc. Before cultivation, the substrate needs to be sterilized at normal pressure and high temperature, so a normal pressure and high temperature sterilization cabinet is used.

[0003] The atmospheric pressure high-temperature sterilization cabinet for morel mushroom spawn mainly consists of a stainless steel cabinet (including an insulation layer), a steam heating system (steam generator / boiler), a temperature control system (thermometer or sensor), a steam circulation system (air inlet and exhaust outlet), a drainage system (bottom drain outlet), and safety devices (safety valve and interlock device). In use, first evenly place the spawn into the cabinet to check for airtightness, then heat. Open the exhaust outlet to release cold air for 10-15 minutes, then close the exhaust outlet and maintain sterilization at 100℃ for 8-12 hours. After sterilization, allow it to cool naturally to below 60℃ before opening the cabinet door and removing the spawn.

[0004] However, during the material loading process, due to the height difference between the inner wall of the disinfection cabinet and the ground, a ramp is usually required to assist in pushing the material rack in. This method not only requires more effort to push the rack, making it inconvenient to put the rack into the disinfection cabinet, but also affects loading efficiency and increases labor intensity. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a culture medium feeding mechanism and an atmospheric pressure sterilization device, making it more labor-saving to feed materials onto the sterilization cabinet.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a culture medium feeding mechanism, including a ramp plate connected to a disinfection cabinet body, an opening groove on the bottom surface of the disinfection cabinet body, a threaded rod rotatably connected in the opening groove, one end of the threaded rod passing through the disinfection cabinet body and connected to a rotary motor, the rotary motor being fixed to the back of the disinfection cabinet body, a slider threadedly connected to the outer wall of the threaded rod, a pull plate structure connected to the top surface of the slider, and a stop bar rotatably connected to the end of the pull plate structure for limiting the material rack.

[0007] Furthermore, the pull plate structure includes a first plate, a second plate, and a third plate, wherein the first plate is rotatably connected to the slider, the second plate is rotatably connected to the first plate, and the third plate is rotatably connected to the second plate.

[0008] Furthermore, the top surface of the third plate is provided with an installation groove, and a rotating shaft is rotatably connected in the installation groove. One end of the stop rod is fixedly sleeved on the outside of the rotating shaft, and one end of the rotating shaft passes through the installation groove and is threadedly connected to a threaded ring. The inner wall of the threaded ring abuts against the outer wall of the end of the third plate.

[0009] Furthermore, a handle is fixedly connected to the outer wall of the threaded ring.

[0010] Furthermore, a slot is provided at the top of the slider, and a locking block is engaged in the slot. The first plate is rotatably connected to the locking block.

[0011] Furthermore, a limit rod is threadedly connected to the top of the card block, and one end of the limit rod passes through the card block and is threadedly connected to the slider.

[0012] An atmospheric pressure sterilization device includes a sterilization cabinet body and the aforementioned feeding mechanism.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This invention utilizes a rotary motor, threaded rod, slider, pull plate structure, and stop bar to enable the material rack to move synchronously with the stop bar and pull plate structure, allowing the material rack to slide into the disinfection cabinet body. This design optimizes the laborious traditional manual pushing of the material rack into a lightweight operation requiring only assistance in moving the rack uphill and into the cabinet, reducing worker fatigue. Simultaneously, the stability of the mechanical transmission improves the smoothness and safety of the loading process. The structure is simple, easy to operate, and highly practical.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] like Figures 1 to 5 As shown, a culture medium feeding mechanism includes a ramp 2 connected to a disinfection cabinet body 1. An opening groove 4 is provided on the bottom surface inside the disinfection cabinet body 1. A threaded rod 3 is rotatably connected in the opening groove 4. One end of the threaded rod 3 passes through the disinfection cabinet body 1 and is connected to a rotary motor 6. The rotary motor 6 is fixed to the back of the disinfection cabinet body 1. A slider 7 is threadedly connected to the outer wall of the threaded rod 3. A pull plate structure 5 is connected to the top surface of the slider 7. A stop bar 8 for limiting the material rack is rotatably connected to the end of the pull plate structure 5.

[0023] like Figures 1 to 5 As shown, when the culture medium feeding mechanism and atmospheric pressure sterilization device of this utility model are in use, when the material rack needs to be pushed into the sterilizer body 1, the material rack can be pushed to the slope plate 2, and then the rotary motor 6 is started. When the rotary motor 6 rotates, it drives the threaded rod 3 to rotate. When the threaded rod 3 rotates, it drives the slider 7 to move under the restriction of the opening slot 4, so that the slider 7 moves forward and drives the pull plate structure 5 to move to the slope plate 2 until it is located at the bottom of the material rack. Then, according to the position of the material rack, the stop rod 8 is rotated first so that the stop rod 8 blocks the outer wall of the material rack. Then, the rotary motor 6 flips, drives the threaded rod 3 to flip, drives the slider 7 to move backward, and drives the pull plate structure 5 to move backward. When the pull plate structure 5 moves backward, it drives the stop rod 8 to move backward. The stop rod 8 drives the material rack to move past the slope plate 2 into the sterilizer body 1.

[0024] Before the stop bar 8 moves, the worker should stand on the outside of the material rack and support the material rack to prevent it from moving left or right. In specific applications, the feeding mechanism can be two sets and set symmetrically, so that the stop bar 8 can be more stable when pulling the material rack into the disinfection cabinet body 1.

[0025] Through the design of the rotary motor 6, threaded rod 3, slider 7, pull plate structure 5, and stop bar 8, the material rack can move synchronously with the stop bar 8 and pull plate structure 5, thereby allowing the material rack to slide into the disinfection cabinet body 1. This design optimizes the laborious operation of manually pushing the material rack into a lightweight operation that only requires assisting the material rack to complete the uphill and cabinet entry, reducing the labor intensity of workers. At the same time, the stability of the mechanical transmission improves the smoothness and safety of the material loading process.

[0026] like Figure 2 and Figure 3 As shown, the pull plate structure 5 includes a first plate 51, a second plate 52 and a third plate 53. The first plate 51 is rotatably connected to the slider 7, the second plate 52 is rotatably connected to the first plate 51, and the third plate 53 is rotatably connected to the second plate 52.

[0027] Specifically, in order to ensure that the pull plate structure 5 moves more smoothly uphill into the disinfection cabinet body 1 along with the material rack, the pull plate structure 5 is set as a first plate 51, a second plate 52 and a third plate 53 that are hinged to each other. In this way, the pull plate structure 5 can be flexibly adjusted and pulled easily when passing the slope plate 2 and the bottom surface inside the disinfection cabinet body 1.

[0028] like Figure 3 and Figure 5 As shown, the top surface of the third plate 53 has an installation groove 9, and a rotating shaft 12 is rotatably connected in the installation groove 9. One end of the stop rod 8 is fixedly sleeved on the outside of the rotating shaft 12. One end of the rotating shaft 12 passes through the installation groove 9 and is threadedly connected to a threaded ring 13. The inner wall of the threaded ring 13 abuts against the outer wall of the end of the third plate 53.

[0029] Specifically, the stop bar 8 is set at a certain height to limit the material rack. The stop bar 8 can be rotated in the mounting groove 9, which facilitates the smooth entry of the third plate 53 into the bottom of the material rack, that is, between the wheels on both sides of the bottom of the material rack. After the third plate 53 passes through the material rack, the stop bar 8 can be rotated in the mounting groove 9 to drive the rotating shaft 12 to rotate. When the stop bar 8 is rotated vertically, the threaded ring 13 can be rotated to lock the outer end of the rotating shaft 12. Through friction, the vertical state of the stop bar 8 is locked.

[0030] like Figure 5 As shown, a handle 14 is fixedly connected to the outer wall of the threaded ring 13. The handle 14 facilitates the rotation of the threaded ring 13.

[0031] like Figure 3 and Figure 4 As shown, the top of the slider 7 has a slot 10, and a block 11 is engaged in the slot 10. The first plate 51 is rotatably connected to the block 11.

[0032] Specifically, in order to avoid the pull plate structure 5 and the stop bar 8 from affecting the normal disinfection of the disinfection cabinet body 1, the pull plate structure 5, together with the card block 11, can be separated from the card slot 10. The pull plate structure 5 and the stop bar 8 can be disassembled and stored separately. When it is necessary to load materials, they can be reassembled for use.

[0033] like Figure 4 As shown, a limiting rod 15 is threadedly connected to the top of the locking block 11. One end of the limiting rod 15 passes through the locking block 11 and is threadedly connected to the slider 7. Inserting the limiting rod 15 into the locking block 11 and then threading it to the slider 7 prevents the locking block 11 from detaching from the locking slot 10.

[0034] An atmospheric pressure sterilization device includes a sterilization cabinet body 1 and the aforementioned feeding mechanism.

[0035] The rotary motor 6 in the above structure is a forward and reverse rotating motor, which is a mature existing technology.

[0036] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
