Description
Technical field
The present invention relates to a kind of accurate cutting type negative pressure concrete graded layer with scale and get powder device, can be used for having turning powder the concrete experiments of accuracy requirement.
Background technology
In the research of the rule of development that inside concrete is destroyed, need to adopt the concrete powder of the different degree of depth to be dissolved in water and carry out then pH value test, thereby draw the rule of development of inside concrete. So the relative position of getting the powder degree of depth and getting each time powder is had to very high requirement, but currently used concrete get powder equipment adopt rotate abrasive dust get powder device, take fully enough powder though can turn, but concrete is got to the control that powder position and the degree of depth can not be strict, and the impact that experimental result is produced is larger.
Summary of the invention
Get powder device and can only successively get powder at concrete surface in order to overcome existing concrete, but can not accurately determine the powder amount of getting each time, can not determine and turn the degree of depth of getting powder, Shortcomings aspect the regularity of distribution of the research deteriorated degree of depth of inside concrete and inside concrete, the invention provides a kind of novel concrete and get powder device, this gets powder device can not only successively successively get powder at concrete surface, and can easily control the powder amount of getting each time, and concrete is got the powder degree of depth.
The technical solution used in the present invention:
A kind of negative pressure concrete is accurately got powder device, it comprises box body, box body is provided with plexiglass tent, between box body and plexiglass tent, connect by hinge, be provided with the fixed mount of concrete test block in box body, fixed mount is provided with the screw rod for fixing test block, box body front is provided with lower graduation mark, right side, box body upper end is provided with screw, and box body upper end is also added with movable capping, is positioned at and reads lower quarter to locate to be relatively provided with high scale line above line in movable capping; The position that movable capping and box body slide is provided with chute, passes through rotating screw bolt relative sliding, and fix by screw rod and geometrical clamp between activity capping and box body, adopts welding between geometrical clamp and nut; In movable capping, graduation mark is interval with two plate washers and forms vertical track vertically, between two plate washers, and be provided with cutter seam parallel with two baffle plates.
Plexiglass tent upper surface is provided with hole, and hole is connected with negative pressure dust collector, between hole and negative pressure dust collector, is provided with screen pack.
Plexiglass tent side is provided with multidirectional passage, and multidirectional passage is connected with air blast.
The technique effect that the present invention obtains: the present invention can in the time getting powder, control easily get the powder degree of depth and every one deck get powder thickness, simple in structure, simultaneously get aspect powder convenient to operation.

Detailed description of the invention
Structure of the present invention is referring to Fig. 1-5, a kind of negative pressure concrete is accurately got powder device, it comprises box body 15, box body is provided with plexiglass tent 14, between box body and plexiglass tent, connect by hinge 2, in box body 15, be provided with the fixed mount 17 of concrete test block, fixed mount 17 is provided with the screw rod 13 for fixing test block, box body front is provided with lower graduation mark 8, right side, box body upper end is provided with screw 9, box body upper end is also added with movable capping 19, is positioned at and reads lower quarter to locate to be relatively provided with high scale line 3 above line in movable capping; The position that movable capping 19 and box body slide is provided with chute 16, passes through rotating screw bolt 10 relative slidings between activity capping 19 and box body 15, and fixing by screw rod 4 and geometrical clamp 11, adopts welding between geometrical clamp 11 and nut 12; In movable capping, graduation mark is interval with two plate washers 6,7 and forms vertical track vertically, between two plate washers, and be provided with cutter seam 18 parallel with two baffle plates.
Plexiglass tent 14 upper surfaces are provided with hole 1, and hole 1 is connected with negative pressure dust collector 21, between hole 1 and negative pressure dust collector 21, are provided with screen pack 5.
Plexiglass tent 14 sides are provided with multidirectional passage 20, and multidirectional passage 20 is connected with air blast 22.
Design of the present invention and use principle are as follows: the present invention is in the device of a surrounding sealing, the fixed mount of a built-in concrete test block; Adopt movable capping above, chute is set, can horizontally slip easily by rotating screw bolt, also can fix with bolt simultaneously; On lid, drive a very narrow cutter of crossing and stitch 18, can put into the blade of stonecutter, baffle plate 6,7 is set in stonecutter both sides simultaneously and forms a vertical track, ensure that stonecutter can only move forward and backward and can not move left and right in capping; And then on whole device, add the machine cloche 14 with circular opening, and prevent that the concrete powder cutting from being taken out of by blade, also can facilitate people's hand operated simultaneously. Cut the box of powder device and the front of lid adds respectively rule, facilitating reading. Putting into concrete test block covers slip lid and makes blade in concrete outward flange, and cover cloche and fix, energising, use hand propelled stonecutter, then unclamp slip lid, it is fixing again that rotating screw bolt is pressed scale slip slip lid, just can carry out the cutting of lower one deck, open simultaneously negative pressure dust collector 21 and air blast 22 just can clear up easily with collecting hood in powder, so just controlled successively get the every one deck of powder get powder thickness, also have the degree of depth apart from concrete surface. Thereby facilitate coagulation powder sample to obtain experiment, and then reach the object of the inner deteriorated rule of development of research concrete material.
