cavity 31, the guide block 27 can be driven to reciprocate back and forth along the sliding fit direction of the slide block 28 and the sliding chute 29, because the bottom surface of the discharging pipe 18 and the top surface of the guide block 27 are of the inclined structure with the same inclination, and when the guide block 27 is located at the foremost position, the lower side opening end of the discharging pipe 18 is just completely closed, so that the concrete flowing out from the discharging pipe 18 can flow outwards in an interrupted manner, and the concrete amount that flows out every time is the same, therefore the staff can limit the discharge amount through the structure, the staff is greatly convenient for the staff to control and limit the concrete discharge amount, the condition of insufficient use or waste is avoided, the practicability and convenience of the device are effectively improved, as mentioned above, the rotary disc 10, the stirring column 11 and the discharge amount limiting component 26 in the device are all driven by the same motor 14, therefore, a large amount of power resources can be saved, the cost is saved at the same time, when the concrete discharge amount reaches the preset value, the staff can screw the hand screwing disc 23 for 90 degrees, under the driving of the rotary column, the baffle 19 can return to the original position and make the sealing ring 20 on the outer wall of the baffle clamped with the annular groove 21, thus, the sealing of the discharge pipe 18 can be realized, and the concrete can be prevented from flowing outwards continuously, the precision of controlling concrete discharge amount is further improved, and the excessive concrete drawn out from the concrete storage tank can be temporarily accumulated in the transition cavity 7, and can not be solidified under the stirring of the stirring column 11, so that the waste is avoided.
The foregoing shows and describes the general principles, essential features, and advantages of the invention.
