Through the threaded connection, the discharge pipe 4 can be conveniently disassembled from the stirring tank 2, so that the discharge pipe 4 can be conveniently cleaned. The shape of the discharge pipe 4 is that a vertically shaped tubular object at one end is connected with an inclined tubular object at one end, and the inside of the discharge pipe 4 is provided with a valve.

[0045] Working principle: in use, the motor 371 drives the gear one 372 to rotate, so that the gear one 372 drives the gear two 373 to rotate, and then the gear two 373 drives the sliding rod 361 to rotate, and then the sliding rod 361 drives the rotating sleeve 31 to rotate, so that the rotating sleeve 31 drives the rotating frame 33 to rotate, so that the rotating frame 33 mixes the concrete and the sand in the stirring tank 2 during rotation.

[0046] Since the slide bar 361 is located at the left position of the rotating sleeve 31 under the elastic force of the spring 362, the rotating frame 33 and the baffle 367 are in the position of being perpendicular to each other, and the inside of the rotating frame 33 has the hole for the material flow, so that the concrete and the sandstone can be mixed smoothly.

[0047] When the worker needs to take the material, the handle 376 is pushed to the right first, so that the handle 376 drives the slide block 375 to move from the circumferential part of the slide 374 to the horizontal part, and then drives the slide bar 361 to move to the right by extruding the inner wall of the slide 374.

[0048] When the slide bar 361 moves to the right relative to the rotating sleeve 31, the slide bar 361 drives the connecting rod 363 to move to the right, so that the connecting rod 363 drives the control block 364 to move to the right, so that the control ball 365 moves to the right under the drive of the control block 364. Since the control ball 365 is located in the spiral area of the control groove 368, when the control ball 365 rotates, the rotating shaft 366 rotates to the position that the control groove 368 and the control ball 365 match each other, so that the rotating shaft 366 rotates, thereby driving the baffle 367 to rotate.

[0049] When the baffle 367 rotates to the horizontal position with the rotating frame 33, the material cannot pass through the rotating frame 33.

[0050] At the same time, in the process that the worker pushes the handle 376 to the right, the slide bar 361 also drives the driving rod 386 to move to the right, so that the driving rod 386 drives the connecting ring 385 to move to the right, so that the connecting ring 385 drives the push block 384 to move to the right, so that the push block 384 pushes the blocking block 381, so that the inclined surface of the blocking block 381 is forced to move to the direction of entering the mixing tank 2.

[0051] At the same time, when the worker moves the handle 376, the gear two 373 and the gear one 372 are in different planes, so that the gear two 373 cannot rotate under the drive of the gear one 372, so that the worker first places the container for receiving the material at the lower end of the discharge pipe 4, opens the valve of the discharge pipe 4, and then rotates the handle 376 upward, so that the handle 376 drives the slide bar 361 to rotate, and the slide bar 361 drives the rotating sleeve 31 to rotate.

[0052] When the rotating sleeve 31 rotates, the rotating frame 33 closest to the blocking block 381 is in contact with the blocking block 381, so that the rotating frame 33 cannot move, and the other rotating frames 33 still rotate with the rotating sleeve 31, so that the material can leave the mixing tank 2 from the discharge pipe 4 under the drive of the other moving rotating frame 33.

[0053] When the discharging is completed, the worker closes the valve and releases the handle 376, at this time the slide rod 361 is reset under the drive of the spring 362, so that the gear two 373 returns to the position of engaging with the gear one 372, and when the handle 376 rotates to the position of engaging with the magnetic position of the positioning column 377, the handle 376 moves to the left under the action of the magnetic force, so as to be adsorbed by the positioning column 377, so that the sliding block 375 enters the annular area, thereby facilitating the worker to take next time.

[0054] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and not for limiting the present application, although the foregoing embodiments of the present application are described in detail, for those skilled in the art, it still can be modified, or part of the technical features of the equivalent replacement, within the spirit and principles of the present application, any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
