[0020] The technical solutions in the embodiments of this utility model will be clearly and completely described below.

[0021] like Figures 1-6As shown, a scraper shaft locking device includes a locking seat 1. A clamping opening 2 is machined on the side of the locking seat 1, and interlocking inclined surfaces 3 are machined on both sides of the clamping opening 2. A pin hole is machined in the middle of the clamping opening 2, and a locking pin 4 is disposed within the pin hole. A pin shaft hole 5 is machined at the pin head of the locking pin 4. Sleeve mounting holes are machined on both sides of the locking pin 4, and right-hand guide sleeves 6 and left-hand guide sleeves 7 are respectively disposed within the screw sleeve mounting holes. A locking hole is machined in the radial direction within the locking pin 4, and a guide screw 8 passes through the locking hole. A right-hand thread 9 and a left-hand thread 10 are machined on the guide screw 8, which are respectively connected to the right-hand guide sleeve 6 and the left-hand guide sleeve 7. To ensure stable movement of the right-hand guide sleeve 6 and the left-hand guide sleeve 7, guide grooves 11 are machined around their periphery. A set screw 12 is installed on the side of the screw sleeve mounting hole, and the end of the set screw 12 is engaged in the guide groove 11.
