31 buckle, and motor 61 works and rotating bar 62 is driven to be rotated, and rotating bar 62 is by driving transport screw leaf 63 to be driven
Concrete moves up, while rotating bar 62 drives reverse acting spiral leaf 65 to rotate by transmission component 64,65 band of reverse acting spiral leaf
Dynamic concrete moves down, and in this way while being stirred to concrete, drives concrete to carry out moving up and down repeatedly, makes
The bubble for obtaining 3 bottom of mud cap can more quickly be moved to the top of mud cap 3 and squeeze out from venthole, improve coagulation
The stirring efficiency of soil.
Rotating bar 62 rotates and first gear 641 is driven to be rotated, and first gear 641 with second gear 643 by nibbling
It closes to drive multiple second gears 643 while rotate, then second gear 643 drives connector sleeve 644 to turn in the lower section of cup lid 31
It is dynamic, and then connector sleeve 644 drives reverse acting spiral leaf 65 to be rotated, while meeting between transport screw leaf 63 and reverse acting spiral leaf 65
There is a certain distance to guarantee that flowing up and down for concrete will not influence each other, the stirring efficiency of concrete is higher.
Rotating bar 62 is connected by multiple first connecting rods 621 with transport screw leaf 63, fixing-stable, and transport screw
There is certain gap between leaf 63 and rotating bar 62, transport screw leaf 63 can be upward by its concrete between rotating bar 62
Conveying, while first connecting rod 621 can play the effect of stirring to the concrete between transport screw leaf 63 and rotating bar 62,
More efficiently.Connecting plate 646 is fixed reverse acting spiral leaf 65 by multiple connecting plates 646 of lower section, multiple connecting plates
Stock inlet between 646 can facilitate the entrance of the concrete in outside, and multiple second connecting rods 647 can be to reverse acting spiral
Leaf 65 carries out stable fixation, while the second connecting rod 647 can play the effect centainly stirred, and stirring efficiency is higher.Even
During female connector 644 rotates, limit sleeve 645 is followed by connector sleeve 644 and is rotated, while limit sleeve 645 can be to connection
The top of set 644 is limited, to prevent limit sleeve 645 from shifting.
The outer ring surface of connector sleeve 644 is evenly arranged with multiple balls 6441, the lateral wall rolling of ball 6441 and connector sleeve 644
Dynamic connection, the inner sidewall of the outer ring surface and link slot 312 of ball 6441 are affixed, and when connector sleeve 644 rotates, ball 6441 can edge
The inner sidewall of link slot 312 rolled, it is more convenient to reduce friction of the connector sleeve 644 in rotation.
