Embodiment
Below in conjunction with accompanying drawing, the technical solution of the utility model is described in detail.
As shown in Figure 3 and Figure 4, a kind of helical feed squeezing machine of the present utility model comprises step-down gear 1, dreg-accepting hopper 2, tank 3, spiral slot 4, residue outlet 5 and does not have a spiral 6.Step-down gear 1 is positioned at the end outside of spiral slot 4, and the other end of spiral slot 4 is fixedlyed connected with residue outlet 5, does not have axle spiral 6 and is positioned at spiral slot 4, and dreg-accepting hopper 2 is positioned at the top of spiral slot 4, and tank 3 is positioned at the bottom of spiral slot 4.Residue outlet 5 is the state of being inclined upwardly.The left end that does not have axle spiral 6 is provided with left side axle 61, and the right-hand member that does not have axle spiral 6 is provided with right axle 62, and the middle part of not having axle spiral 6 is no Spindle Status.Not having the left side axle 61 of axle spiral 6 or right axle 62 fixedlys connected with the output shaft of step-down gear 1.Left side axle 61 and right axle 62 occupy two pitches respectively in not having axle spiral 6 distance is good.Left side axle 61 and right axle 62 are oversize, and waste material can hinder the guiding to the grid slag on the other hand on the one hand.
