[0030] See also Figure 1 and Figure 3 The blade assembly 13 includes a blade rack 131 and a blade plate 132. A slide groove 133 is provided in the middle of the blade rack 131, and the blade plate 132 is embedded in the slide groove 133. A card slot 134 is further provided on the inner side of the slide groove 133 above the blade plate 132. A buckle 135 is clamped in the card slot 134. The buckle 135 is an Ω-shaped elastic member, and square clamping blocks 136 matching the card slot 134 are fixedly connected at both ends. When the blade plate 132 is initially installed or subsequently replaced, the blade plate 132 can be inserted into the card slot 134 along the slide groove 133, and the buckle 135 can be embedded to prevent the blade plate 132 from falling out during operation, which greatly improves the convenience of installation and removal of the blade plate 132.

[0031] See also Figure 1 The outer top of the pill inlet pipe 7 is detachably fixedly connected with a pill inlet hopper 15 to facilitate the addition of sand pills.

[0032] See also Figure 1 A bearing 16 is sleeved between the main shaft body 9 and the shaft seat 8, and sealing rings 17 are nested and connected at both ends of the shaft seat 8, so that the rotation of the main shaft body 9 is more stable.
