Abstract
The invention discloses a shield machine screw conveyor gate, and belongs to the shield machine screw conveyor part. The gate is used for the deslagging at the middle position of a screw conveyor of a double helix shield machine. The opening and closing of a left gate and a right gate can be achieved through controlling the retraction and extension of two oil cylinders. The left and right gates can be opened by moving relatively to each other. The left and right gates move in the same plane. The control manner is simple. The connection and disconnection between two screw conveyors can be achieved through controlling the opening of the gates. A middle deslagging gate is arranged between two screw conveyors can upgrade the safety of the double helix shield machine. The shield machine screw conveyor gate belongs to the technical field of screw conveyors.

Right gate is provided with arc and opens mechanical position limitation block, and mechanical position limitation block is fixed with gate installation by hexagon socket head cap screw, safely may be used
Lean on, by controlling, two oil cylinders are flexible to be realized left gate, right gate opening and close, and left gate, right gate are the relative fortune in left and right
Dynamic enabling form, left gate, right gate are moved on the same plane, and control mode is simple.
Further, the oil cylinder two ends are connected with left gate, right gate, and by controlling, two oil cylinders are flexible to realize left lock
Door, right gate opening and closing, control mode are simple.
Further, the left gate, right gate height are consistent with conveying worm cylinder internal diameter, do not have gate concave slide groove not
Easily product is native, and gate opening is more smooth with closing.
Further, the gate both sides are respectively provided between twice packing_seal, packing_seal equipped with sealed briquette, sealed briquette
Inside is provided with grease channel and packing_seal is lubricated.
Compared with prior art, the beneficial effects of the invention are as follows：By controlling, two oil cylinders are flexible to realize left lock to the present invention
Door, right gate opening and closing, left gate, right gate are left and right relative motion enabling form, and left gate, right gate are same flat
Face is moved, and control mode is simple.Left gate, right gate both sides are respectively provided between twice packing_seal, packing_seal and are pressed equipped with sealing
Block, is provided with grease channel and packing_seal is lubricated inside sealed briquette.Left gate, right gate height and helical feed machine barrel
Internal footpath is consistent, and no gate concave slide groove is difficult product soil, and gate opening is more smooth with closing.
