Description

Technical Field

[0001] This utility model relates to the field of rice seedling cultivation technology, specifically a multi-point aeration device for rice seedling substrate fermentation. Background Technology

[0002] In the traditional rice seedling substrate fermentation process, insufficient turning leads to uneven aeration and low fermentation efficiency. Existing turning equipment is mostly a single mechanical turning method, lacking a multi-point aeration design. The aeration principle for seedling raw materials is to increase the contact time with air by turning, but traditional turning has a short contact time with air, which easily creates anaerobic zones. In addition, the problems of raw materials flying around and bottom material accumulation during turning are not effectively solved, affecting the fermentation quality.

[0003] Therefore, there is an urgent need for a multi-point aeration device for rice seedling substrate fermentation. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a multi-point aeration device for rice seedling substrate fermentation, which solves the problem of insufficient fermentation of seedling substrate. By adding a turning mechanism and a pushing mechanism to the traditional turning machine, the contact time between the substrate raw materials and air is increased, thus accelerating the fermentation efficiency.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a multi-point aeration device for rice seedling substrate fermentation, comprising a fermentation tank, a movable turning machine at the upper end of the fermentation tank, a drive motor at the front end of the turning machine, the drive motor being connected to a rotating rod via a transmission wheel set to drive the turning plates to rotate and turn the raw materials, a rotating rod and a fixed plate inside the turning machine, an air outlet on the fixed plate, a blower fixed to the outside of the fixed plate, the blower being matched with the air outlet, and multiple L-shaped turning plates with equal spacing fixed on the rotating rod, with perforations on the turning plates.

[0006] Furthermore, the lower end of the fixed plate is provided with a pushing mechanism, which includes an upper shovel plate and a lower shovel plate. The upper shovel plate has multiple perforations, and the lower shovel plate abuts against the bottom of the fermentation tank.

[0007] Furthermore, the fixed plate has an upper discharge hole and a lower discharge hole. The raw material scooped up by the upper shovel plate falls through the hole and is then scooped up again by the lower shovel plate and discharged from the lower discharge hole.

[0008] Furthermore, a rocker plate is fixed to the outer end of the lower discharge hole, and a strip hole is opened on the rocker plate to lift the raw material and increase the drop.

[0009] Furthermore, the blower slowly blows air into the turning machine through the air outlet to prevent raw materials from flying away.

[0010] Furthermore, the flaps are arranged in a spiral pattern.

[0011] This invention provides a multi-point aeration device for rice seedling substrate fermentation. Compared with the prior art, it has the following advantages:

[0012] This rice seedling substrate fermentation multi-point aeration device achieves multiple turning and lifting of raw materials through spirally distributed L-shaped flippers and multi-layer pushing mechanism. Combined with the slow air delivery by the blower, it significantly improves the uniformity of contact between raw materials and air. The synergistic effect of the upper shovel, lower shovel, and tilting plate increases the material drop, prolongs the aeration time, and avoids anaerobic fermentation. The perforated and strip-shaped hole design reduces raw material flying and improves fermentation efficiency and quality. Attached Figure Description

[0020] 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.

[0021] Please see Figures 1-6This utility model provides a technical solution: a multi-point aeration device for rice seedling substrate fermentation; specifically, it includes a fermentation tank 1, in which substrate raw materials are piled up for fermentation. A turning machine 2 is movable at the upper end of the fermentation tank 1, and a drive motor 3 is fixed at the front end of the turning machine 2. A transmission wheel set is fixed at the output end of the drive motor 3. A rotating rod 4 is rotatably installed inside the turning machine 2, and the rotating rod 4 is driven to rotate by the drive motor 3 and the transmission wheel set. This is a prior art technology. The technique will not be described in detail here; a fixed plate 7 is fixed inside the turning machine 2, and an air outlet 9 is opened at the upper end of the fixed plate 7. A blower 8 is fixedly connected to the outside of the fixed plate 7, and the output end of the blower 8 is fixedly connected to the air outlet 9. The blower 8 blows air into the interior of the turning machine 2. The blowing speed is slow to avoid the raw materials flying. A turning mechanism is set on the rotating rod 4. The turning mechanism turns the raw materials up. After being turned up, the blower 8 blows air to allow the raw materials to fully contact the air and improve the fermentation efficiency.

[0022] The turning mechanism includes a turning plate 5, which is L-shaped and inclined at the end. Multiple holes 6 are provided on the turning plate 5 and are evenly spaced. The turning plate 5 rotates by the rotation of the rotating rod 4, thereby turning the upper part of the raw material. Turning can bring it into contact with air, thereby improving the fermentation efficiency. At the same time, the turning plate 5 is spirally distributed on the rotating rod 4, which improves the turning efficiency.

[0023] A pushing mechanism is fixedly connected to the lower end of the fixed plate 7. The pushing mechanism includes an upper shovel plate 11 with perforations 12. The number of perforations 12 is multiple and they are staggered with equal spacing. When the turning machine 2 moves, it shovels the raw material at the bottom through the upper shovel plate 11. The shoveled raw material falls into the fermentation tank 1 through the perforations 12. There is a drop when the raw material falls from the upper shovel plate 11, which increases the contact time with the air. A lower shovel plate 14 is fixed at the lower end of the fixed plate 7. The lower shovel plate 14 is set against the lower end of the fermentation tank 1. The raw material falling through the upper shovel plate 11 is shoveled up again by the lower shovel plate 14. An upper discharge hole 10 and a lower discharge hole 13 are opened at the lower end of the fixed plate 7. The raw material shoveled by the upper shovel plate 11 falls into the lower end and is then shoveled up by the lower shovel plate 14 and discharged from the lower discharge hole 13, which increases the contact time with air.

[0024] A rocker plate 15 is fixed on the outer side of the lower discharge hole 13 of the fixed plate 7. The rocker plate 15 has multiple strip holes 16 with equal spacing. The raw material scooped up from the lower discharge hole 13 is lifted again by the rocker plate 15, and the lifted raw material increases the drop and comes into contact with the air.
