Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

The utility model provides a concrete mixer, as shown in fig. 1, fig. 2, including frame 1, 1 upper end fixedly connected with opening ascending agitator 2 of frame, frame 1 is connected with the (mixing) shaft 3 that one end stretches into in agitator 2 in 2 lower extremes of agitator rotate along vertical direction, frame 1 is used for driving (mixing) shaft 3 pivoted agitator motor 4 in agitator downside still fixedly connected with, 3 lower extreme fixedly connected with driving disc 31 of (mixing) shaft, driving disc 31 passes through the output shaft of drive belt 32 with agitator motor 4. 2 back of the body both sides of agitator 2 are mutually along the equal fixedly connected with arc 5 of vertical direction, and 5 up end of arc have seted up standing groove 51 along self length direction, and equal sliding connection has striker plate arc 6 in every standing groove 51, when the mixer begins to stir, pulls up striker plate arc 6 from standing groove 51 to prevent that the material from splashing at will when the stirring, avoid polluting the production environment.

As shown in fig. 2, fig. 4 and fig. 6, fixing pieces 7 for fixing the arc-shaped baffle are installed at both ends of the bottom wall of the arc-shaped plate 5 and the bottom wall of the placing groove 51, each fixing piece 7 comprises a fixing rod 71 which is penetrated through and arranged at both ends of the bottom wall of the placing groove 51 along the vertical direction and is connected with the arc-shaped plate 5 in a rotating manner, the cross section of each fixing rod 71 is circular, fixing holes 61 for the fixing rods 71 to be clamped into are formed in both ends of the material blocking arc-shaped plate 6 along the vertical direction, the fixing rods 71 are clamped into one end fixedly connected with fixing blocks 711 of the material blocking arc. The retaining arc plate 6 is provided with a connecting hole 62 along the vertical direction on the side wall of the fixing hole 61 for the fixing block 711 to be clamped and slide, and the lower end of the retaining arc plate 6 is provided with a fixing groove 63 on the side wall of the connecting hole 62 for the fixing block 711 to be clamped. After the arc striker plate 6 is pulled up, the rotating handle 72 is held by a hand and rotated by 90 degrees, so that the fixing block 711 on the fixing rod 71 is clamped into the fixing groove 63 in the arc striker plate 6, and the arc striker plate 6 is fixed in the placing groove 51.

As shown in fig. 2 and 6, a fastening bolt 73 for tightly abutting against the lower end face of the arc plate 5 is connected to the rotating handle 72 through a thread, a fastening plate 74 for tightly abutting against the lower end face of the arc plate 5 is fixedly connected to the upper end of the fastening bolt 73, and an anti-slip groove 741 is integrally formed on one side of the fastening plate 74 facing the arc plate 5. After the fastening bolt 73 is screwed, the fastening plate 74 is tightly attached to the lower end face of the arc-shaped plate 5, and the anti-slip threads 741 can increase the roughness of the fastening plate 74, so that friction force is generated between one end of the fastening bolt 73 and the arc-shaped plate 5, and the rotating handle 72 is prevented from rotating freely.

As shown in fig. 2 and 6, the fixing rod 71 is sleeved with a buffer spring 8 between the striker plate 6 and the bottom wall of the placing groove 51.
