[0022] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0023] The utility model embodiment discloses an experimental device for evaluating the performance of a drill bit anti-mud balling cleaning agent.

[0025] The cleaning agent can be evenly sprayed on the outer surface of the mud bag 10 through the U-shaped spray plate 3, and then the vibration motor 7 is started. Then, the performance of the cleaning agent can be known by observing the shedding speed of the mud bag 10.
[0026] In order to make the cleaning agent spray more evenly, Figure 1-2 As shown, the driving mechanism includes a driving motor 11, a first bevel gear 12 and a second bevel gear 13. The driving motor 11 is fixedly connected to the lower surface of the base 1, the first bevel gear 12 is fixedly sleeved on the output end of the driving motor 11, and the second bevel gear 13 is fixedly sleeved on the outer surface of the tube body 2 and meshes with the first bevel gear 12.
[0027] The driving motor 11 is started to rotate the first bevel gear 12, and then the second bevel gear 13 is driven to rotate, so that the tube body 2 can rotate, that is, the U-shaped spray plate 3 can rotate, so that the detergent can be sprayed more evenly.
[0028] And in order to make the drill bit 9 can be fixed, as Figure 1-3 As shown, the fixing mechanism includes two fixing blocks 14, two screw rods 15 and two knobs 16.
