Technical Field

[0001] This utility model relates to the technical field of algae cultivation devices, and in particular to a self-propelled scraping device for collecting microalgae biofilm. Background Technology

[0002] like Figure 1 The image shows an existing microalgae cultivation device, which includes a support frame and several layers of cultivation trays fixed on the support frame. One end of each cultivation tray has a hopper that communicates with the next cultivation tray. The cultivation tray is trough-shaped and filled with a layer of culture medium at the bottom for microalgae cultivation. As the number of microalgae increases, they can form a biofilm at the bottom of the cultivation tray. However, since the cultivation tray is at least 10 meters long, manually scraping each layer is extremely inconvenient and reduces production efficiency.

[0003] Therefore, there is an urgent need to design a device that can scrape the microalgae biofilm from the bottom of the culture tray to improve production efficiency. Utility Model Content

[0024] Please see Figures 1 to 6 This utility model provides a self-propelled scraping device for collecting microalgae biofilm, including a movable seat 3 and a track 1 fixed on a support. The movable seat 3 is provided with a drive component 2 that matches the track 1 and moves linearly on the track 1. Several rotatable disc brushes 4 are placed side by side at the bottom of the movable seat 3. Scrapers 5 in the same direction are provided on both sides of the disc brushes 4. The scrapers 5 are fixed on the movable seat 3. The scrapers 5 are used to push and scrape the microalgae biofilm at the bottom of the culture tray.

[0025] The disc brush 4 can wash the microalgae biofilm at the bottom of the culture tray, and the scraper 5 scrapes it twice to ensure that the microalgae biofilm is scraped clean, saving manpower, improving overall efficiency, and realizing the automation of scraping.

[0026] The aforementioned track 1 may include a rack 11 and a linear guide 12. The linear guide 12 is provided with two matching sliders 13, which are fixed on the movable seat 3. The drive assembly 2 is matched with the rack 11 and drives the movable seat 3 to move linearly.

[0027] The scraper 5 is preferably shaped like a bucket and has a cross-sectional shape that matches the inner wall of the culture tray, further ensuring the scraping of the microalgae biofilm.

[0028] As an embodiment of this utility model, the drive assembly 2 includes a mounting base 21 fixed on the movable base 3. A driving gear 23 and a driven gear 24 are rotatably disposed inside the mounting base 21. A pressure gear 25 is integrally disposed on the outer side of the driven gear 24, and the pressure gear 25 meshes with the rack 11. A sliding groove is provided on the outer side of the mounting base 21, through which the rack 11 slides. The pressure gear 25 is located above the rack 11. The driving gear 23 is driven to rotate by a motor 22, which is fixed on the movable base 3.

[0029] Through the cooperation of the pressure gear 25 and the rack 11, the moving seat 3 can be driven to move linearly on the track 1, which is more than 10 meters long.

[0030] The aforementioned motor 22 is preferably a dual-shaft geared motor, saving overall space. As an embodiment of this utility model, a pulley A41 is fixedly mounted on the top of the disc brush 4, such as... Figure 5 As shown, pulley A41 is rotatably mounted on movable seat 3; movable seat 3 is also rotatably mounted with bevel gear A42, and bevel gear B43 driven by motor 22 is meshed on bevel gear A42; pulley B44 is provided at the bottom of bevel gear A42; adjacent pulleys A41 are driven by belt A; pulley B44 is driven by belt B to pulley A41 near the inner wall of the culture tray, ensuring the rotation of disc brush 4.

[0031] Here, the motor 22 drives the active gear 23 with its drive shaft at one end, and drives the bevel gear B43 with its drive shaft at the other end, so that the disc brush 4 and the scraper 5 can run synchronously.

[0032] In addition, protective plates 26 can be provided above and below the sliding groove of the mounting base 21; the protective plates 26 are fixed to the outside of the mounting base 21. A bracket 27 can also be fixed to the movable base 3, and the bracket 27 is bolted to the end face of the motor 22 located on the side of the bevel gear B43 to ensure that the motor 22 is fixed stably. At the same time, a protective cover 28 can be fixed to the mounting base 21, which can cover the bevel gear A42, the bevel gear B43, and the head of the motor 22.

[0033] In use, the rack 11 and linear guide rail 12 are selected according to the length of the support and are bolted to it. The motor 22 drives the pressure gear 25 to move on the rack 11, and the two sliders 13 slide on the linear guide rail 12, providing auxiliary support and ensuring the overall stability of operation. When the scraper 5 at the front end of the moving seat 3 has not completely scraped off the microalgae biofilm, the disc brush 4 removes the microalgae biofilm from the bottom of the culture tray, and the scraper 5 at the rear end of the moving seat 3 scrapes the microalgae biofilm clean from the culture tray. Then, it is transported to the next layer of culture through the funnel on the culture tray, and so on. This invention is installed above each layer of culture tray, which greatly saves manpower and improves work efficiency. Photoelectric sensors can be set at both ends of the support to control the movement position of the moving seat 3, which is not shown in the figure. In addition, Figure 1 The hopper in the design does not interfere with this utility model, as required by the design; further details will not be provided.

[0034] This utility model can be summarized in other specific forms that do not depart from the spirit or main features of this utility model. Therefore, in all respects, the above embodiments of this utility model should only be considered as descriptions of this utility model and not as limitations thereof. The claims specify the scope of this utility model, while the above description does not specify the scope of this utility model. Therefore, any changes within the meaning and scope equivalent to the claims of this utility model should be considered as included within the scope of the claims of this utility model.
