[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0027] In the embodiment, it is given by Figures 1-4 A cell scraping device for cell cultivation. The present utility model includes a bottom plate 1. A first motor 2 is fixedly connected to the bottom of the bottom plate 1. The outer side of the output shaft of the first motor 2 is fixedly connected with a protective box 3 rotatably connected to the bottom plate 1. A clamping device 4 is arranged inside the protective box 3. The outer side of the clamping device 4 is fixedly connected with two clamping plates 5 distributed symmetrically left and right. The top of the bottom plate 1 is fixedly connected with an L - shaped support plate 6. The bottom of the L - shaped support plate 6 is fixedly connected with a first electric push rod 7. The bottom of the first electric push rod 7 is fixedly connected with a mounting plate 8. The bottom of the mounting plate 8 is fixedly connected with a second electric push rod 9. The front side of the second electric push rod 9 is fixedly connected with a fixed frame 10 slidably connected to the mounting plate 8. A scraper 11 is arranged inside the fixed frame 10.

[0028] Among them, an annular groove is arranged inside the bottom plate 1. The bottom of the protective box 3 is fixedly connected with two arc plates 12 both of which are slidably connected to the annular groove.

[0029] In this embodiment, during the actual use process, when the first motor 2 drives the rotation of the protective box 3, the two arc plates 12 below the protective box 3 will also slide in the annular groove to stabilize the rotation direction of the protective box 3.

[0030] Among them, the clamping device 4 includes a second motor 41 fixedly connected to the outside of the protective box 3. A left - right screw rod 42 rotatably connected to the inside of the protective box 3 is fixedly connected to the outside of the output shaft of the second motor 41. The outside of the left - right screw rod 42 is threadedly connected with two transmission blocks 43 respectively fixedly connected to two clamping plates 5.

[0031] In this embodiment, during actual use, the second motor 41 has its own internal power supply. The start of the second motor 41 will drive the left - right screw rod 42 to rotate, and under the action of the thread, the two transmission blocks 43 will move in opposite directions, thereby driving the two clamping plates 5 to move.

[0032] Among them, the opposite sides of the two clamping plates 5 are both arc - shaped, and buffer pads 13 are arranged on the opposite surfaces of the two clamping plates 5.

[0033] In this embodiment, during actual use, the relative movement of the two clamping plates 5 will clamp and fix the culture dish, and the fixation will be made more stable under the action of the buffer pads 13.

[0034] Among them, a threaded hole is opened inside the fixed frame 10. A bolt knob 14 is threadedly connected to the inside of the threaded hole. A pressing plate 15 located inside the fixed frame 10 and in contact with the scraper 11 is rotatably connected to the outside of the bolt knob 14.

[0035] In this embodiment, during actual use, when the bolt knob 14 is turned, the pressing plate 15 will move inward and press the scraper 11, and fix the scraper 11 inside the fixed frame 10.

[0036] Among them, a chute is opened inside the mounting plate 8. A sliding plate 16 fixedly connected to the top of the fixed frame 10 is slidably connected to the chute.

[0037] In this embodiment, during actual use, when the second electric push rod 9 drives the fixed frame 10 to move, the sliding plate 16 will move in the chute, stabilizing the moving direction of the fixed frame 10.

[0038] Working principle:

[0039] First, place the petri dish between two clamping plates 5. Then, start the second motor 41 to clamp and fix it with the two clamping plates 5. Adjust the height of the scraper 11 through the first electric push rod 7 so that the scraping blade position of the scraper 11 can just scrape the bottom surface of the petri dish. Start the first motor 2 to drive the petri dish to rotate by the protective box 3. During the rotation, the scraper 11 will scrape the petri dish. By adjusting the extension length of the second electric push rod 9, the scraping radius of the scraper 11 can be adjusted so that the scraper 11 can scrape the petri dish sufficiently. The scraper 11 can be removed by turning the bolt knob 14 for manual scraping or cleaning the scraper 11.
