The bottom of the slide way 21 is also communicated with a blocking groove 22 for blocking the blocking block 51. The section of the detent groove 22 is a sector of ninety degrees. When the stirring rod 5 is inserted into the insertion hole 20 and the latch 51 abuts against the end of the slide 21, the worker can rotate the stirring rod 5 laterally to rotate the latch 51 into the latch groove 22. When the fixture block 51 is positioned at one end of the clamping groove 22 far away from the slide rail 21, a threaded hole 24 is formed in the side wall of the outer periphery of the stirring rod 2 facing the clamping groove 22, the axis of the threaded hole 24 coincides with the center of the fixture block 51, and the axis of the threaded hole 24 is parallel to the axis of the stirring rod 5; a fastening screw 25 is also threadedly connected in the threaded hole 24.

When the staff is installing fixedly puddler 5 and puddler 2, can insert corresponding slide 21 with puddler 5 at first, when fixture block 51 and slide 21 end touched each other, horizontal rotatory puddler 5, make fixture block 51 slide in the screens groove 22, the staff can be through screwing up fastening screw 25 in screw hole 24, make fastening screw 25's tip contradict on the surface of fixture block 51, the pressure of applying for fixture block 51 through fastening screw 25 has increased the frictional force between fixture block 51 and the screens groove 22, thereby make puddler 5 can fix on puddler 2.

As shown in fig. 3 and 4, a positioning slot 23 engaged with the latch 51 is vertically formed on a side wall of the latch slot 22 away from the threaded hole 24. When the fastening screw 25 abuts against the latch 51 and continues to press the latch 51, the latch 51 slides into the positioning groove 23. And the clamping block 51 is pressed against the bottom surface of the positioning groove 23 by the fastening screw 25, and is clamped and fixed by two side walls of the positioning groove 23 on the one hand, so that the stirring rod 5 and the stirring rod 2 are fixed more stably.

As shown in fig. 5 and 6, when the mixing box is in operation, the mixed material may enter the inside of the chute 21 and block the chute 21 due to the exposed chute 21. In order to solve the problem, after the stirring rod 5 and the stirring rod 2 are fixed to each other, a sealing assembly 54 for sealing the sliding way 21 is further arranged in the sliding way 21, the sealing assembly 54 comprises an insertion rod 541 attached to the outer circumferential surface of the stirring rod 5, one side of the insertion rod 541, facing the stirring rod 5, is fixedly connected with a connecting rod 545 which penetrates through an anti-slip pad 542 and extends out of the insertion rod 541, a connecting hole 52 for accommodating the connecting rod 545 to be inserted is correspondingly formed in the stirring rod 5, one side of the insertion rod 541, to which the connecting rod 545 is fixedly connected, is in an arc shape attached to the circumferential surface of the stirring rod 5, so that the insertion rod 541 can be completely attached to the circumferential surface of the stirring rod 5, the axial direction of the insertion rod 541 is parallel to the axial direction of the stirring rod 5, and; a layer of rubber antiskid pad 542 is fixedly connected to the peripheral surface of the insertion rod 541; an end face of the inserted bar 541 far from the slide rail 21 is fixedly connected with a cover plate 543, the area of the cover plate 543 is larger than the port of the slide rail 21, so that the cover plate 543 can cover the slide rail 21 as a whole, and the cover plate 543 is set as an arc-shaped plate completely attached to the circumferential surface of the stirring rod 2, thereby reducing the gap of the cover plate 543 covering the circumferential surface of the stirring rod 2. In order to enhance the tightness of the mutual fastening between the sealing assembly 54 and the slideway 21, an elastic clamping strip 544 made of rubber is fixed on the circumferential surface of the anti-slip mat 542. A fixing groove 26 for accommodating the elastic clamping strip 544 is formed in the corresponding slide rail 21.

When the fixture block 51 on the stirring rod 5 slides into the fixture block groove 22 and is located below the threaded hole 24, the sealing assembly 54 is located right above the slide rail 21, and along with the fixture block 51 sliding into the positioning groove 23, the sealing assembly 54 also slides into the slide rail 21 and seals the slide rail 21, and at this time, the elastic clamping strip 544 is located in the fixing groove 26 in the slide rail 21 and is attached to the inner wall of the fixing groove 26, so that the tightness of the sealing assembly 54 for sealing the slide rail 21 is improved; the cover 543 covers the end of the chute 21 to reduce the possibility of impurities entering the chute 21 through the gap between the seal 54 and the chute 21.

As shown in FIG. 2, a stirring blade is fixed to the end of the stirring rod 5 away from the stirring rod 2, and the normal line of the stirring blade is inclined at an angle other than ninety degrees to the axis of the stirring shaft. When the stirring rod 2 rotates, the stirring blades can not only turn over the materials along the rotating direction, but also can play a certain effect of turning over the materials in the direction parallel to the axis of the stirring rod 2, so that the stirring efficiency of the concrete stirring box is improved.

The working process is as follows: when a worker installs the stirring rod 5 on the stirring rod 2, firstly, the connecting rod 545 on the sealing assembly 54 is inserted into the connecting hole 52 on the peripheral surface of the stirring rod 5, then the fixture block 51 slides into the slide rail 21, the stirring rod 5 is transversely rotated to enable the fixture block 51 to be clamped into the clamping groove 22, the fastening screw 25 is screwed into the threaded hole 24 to enable the fastening screw 25 to push the fixture block 51 into the positioning groove 23, at the moment, the sealing assembly 54 also enters the slide rail 21 together and closes the slide rail 21, the port of the slide rail 21 of the cover plate 543 is covered, and therefore the interior of the slide rail 21 can be sealed.

The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment without inventive contribution as required after reading the present specification, but all of them are protected by patent laws within the scope of the claims of the present invention.
