[0019] To clearly illustrate the technical features of this solution, the present invention will be described in detail below through specific embodiments and in conjunction with the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application; however, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0020] like Figures 1-2 As shown, in this embodiment, the donkey hide scraping machine includes a flattening component and a scraping component;

[0021] The flattening component comprises a lower fixed plate 1, both sides of which are connected with downwardly extending fixed side plates 2, and between the two fixed side plates 2, there are provided pressing rollers 3 at the front and rear positions respectively, leaving a working area between the front and rear pressing rollers 3, and the lower fixed plate 1 or the two fixed side plates 2 is connected with a traction member 4;

[0022] The fur scraping component comprises an upper fixed plate 5 provided above the lower fixed plate 1, the top of the upper fixed plate 5 is fixedly connected with a motor 6, the output shaft 7 of the motor 6 is sequentially movably penetrated through the upper fixed plate 5 and the lower fixed plate 1 and then extends to the working area to connect a scraper disc 8, the bottom of the scraper disc 8 is distributed with a plurality of radial scrapers 9 along the circumferential direction, a plurality of limiting columns 10 are fixedly connected with the output shaft 7 on the upper fixed plate 5, the lower end of each limiting column 10 is movably penetrated through the lower fixed plate 1 and then connected with a pressing disc 11, and a spring 12 is sleeved on the limiting column 10 between the pressing disc 11 and the lower fixed plate 1.

[0023] Working principle: in use, the animal fur is laid flat, the fur scraping machine is placed on the laid flat fur, the power is plugged in, the switch is turned on, the scraper disc 8 rotates under the driving of the motor 6, and then the radial scrapers 9 thereon realize fur scraping, and the pressing rollers 3 are moved by pulling the traction member 4, so that the continuous fur removing effect is achieved.
