With debug.

Adding appropriate water and dry concrete mix to stirring in hopper 63, starting the driving mechanism stirring hopper 63 two ends, the concrete-agitating stirred in hopper 63 is become water-bearing concreae.

Actuating motor C99, pull the handle of 3-position-3-way hand-operated direction valve, make little oil pump 98 to elevating ram 46 fuel feeding, movable pulley A49 starts to raise, raised by wire rope A drive activity slide type rail system 53, movable pulley B80 is driven again to raise, slide pad system 50 is driven by wire rope B, swing span system 56 and stirring hopper 63 raise, when wheel is touched in oscillating deck 58 contact, swing span system 56 and stirring hopper 63 start 57 to rotate around the shaft, when rotating shaft 57 is higher than when touching wheel 81, the concrete stirred in hopper 63 flows out, fall into concrete hopper B26, when the plunger of elevating ram 46 is raised to the highest, the concrete stirred in hopper 63 is just all poured in concrete hopper B26.At this moment the handle of 3-position-3-way hand-operated direction valve is promoted, under the Action of Gravity Field stirring hopper 63, swing span system 56 and slide pad system 50, the plunger of elevating ram 46 starts to decline, fall the end always, restart to stir water-bearing concreae and---raise---batch turning---whereabouts---stirring water-bearing concreae

Simultaneously, actuating motor B25, motor B25 is by the lower steel liner plate 32 of reductor B35 rotor driven body B30, rotor B38 rotates together with upper steel liner plate 44, water-bearing concreae in concrete hopper B26 constantly falls into the material chamber B29 of rotor block by the blanking port B27 on pressing plate B43, when the material chamber B29 of the rotor block filling water-bearing concreae turns to the position of upper wind path 42, under the high pressure wind action of being in the wind in road 42, water-bearing concreae in the material chamber B29 of rotor block is blown into discharging elbow B39, high-pressure blast in lower wind path 37 blows water-bearing concreae again and enters conveying rubber pipe B70, if the joint number of conveying rubber pipe B70 is more, wind joint can be added in the middle of the access of centre, pressure-air enters conveying rubber pipe B70 through adding air port B87, further promotion water-bearing concreae advances, accelerating admixture from accelerating admixture adder 3 enters in conveying rubber pipe B70 through conveying rubber pipe A20 and accelerating admixture adapter D, spray with water-bearing concreae.

Simultaneously, actuating motor A15, motor A15 is rotated by reductor A16 rotor driven A23, in accelerating admixture hopper 11, accelerating admixture falls into the material chamber A10 of rotor A 23 through blanking port A12, when the material chamber A10 filling accelerating admixture turns to fresh air inlet A7 place, from the high-pressure blast of air compressor machine, through blast pipe A8 the accelerating admixture blowout in rotor material cavity A10, through discharging elbow A18, conveying rubber pipe A19 and accelerating admixture adapter D71 accelerating admixture added again in the water-bearing concreae in conveying rubber pipe B70.
