The specific embodiment
Below in conjunction with embodiment the present invention is done to specify further, but embodiment of the present invention is not limited thereto.
Fig. 1 shows the structural representation of the drilling fluid vibrating sieve that has the anti-cover plate that splashes according to an embodiment of the invention.With reference to an a kind of embodiment shown in Figure 1 with drilling fluid vibrating sieve of the anti-cover plate that splashes; Comprise base 1; Said base 1 top is provided with screen box 4; Be connected with inclination-angle regulating device 5 on the said screen box 4, said inclination-angle regulating device 5 is used for the inclination angle of screen box 4 is regulated, and the inclination angle scope that said inclination-angle regulating device 5 is regulated screen box 4 is for upwarping 6 ° to having a downwarp 3 °.Adjusting device 5 is that a kind of ratchet and pawl arrangement that utilizes drives the secondary and derotation bolt and nut pair of a pair of dextrorotation bolt and nut forward or backwards; Device is elongated or shortened; Raise or reduce screen box front end height; Make screen box rotate a kind of mechanical device of an angle around the rear end, this device is the part of vibrosieve.
Said screen box 4 both sides (about) being provided with fixed support 3, it connects firmly on base through welding, and said fixed support 3 is used for the connection to screen box 4, and said screen box 4 can be suspended on two fixed supports through spring among an embodiment therein.
Because the variation at screen box 4 inclination angles, the unsuitable left and right sides fixed support 3 that utilizes is settled the anti-metal cover board that splashes.Because it is movable with screen box 4 that the drilling fluid vibrating sieve of present embodiment is designed to left and right sides fixed support 3; On the fixed support 3 of activity, settle the anti-metal cover board that splashes again; 4 of cover plate and screen boxs have fixed gap like this; This gap does not change along with the variation at screen box inclination angle, and in order to address this problem, the inventor proceeds following design.
On the top rail 11 of said every side fixed support 3 pivoted arm beam 13 has been installed, said pivoted arm beam 13 1 ends and fixed support 3 are rotationally connected, and one of them embodiment can be that said pivoted arm beam 13 1 ends and fixed support 3 are realized being rotationally connected through first hinge 12; Said pivoted arm beam 13 other ends are connected with inclination-angle regulating device 5, and said inclination-angle regulating device 5 is under the situation of regulating screen box 4 inclination angles, and pivoted arm beam 13 rotates with screen box 4.Like this, when regulating screen box 4 inclination angles, pivoted arm beam 13 rotates with screen box 4, and the variation of relative displacement does not take place basically.
Fig. 2 is the cross-sectional view with reference to C-C shown in Figure 1.As shown in Figure 2, said two pivoted arm beams 13 are provided with rotating first cover plate 21, are connected with baffle plate 26 on said first cover plate 21, and said baffle plate 26 inserts in the screen box 4 and is used to stop mud.As shown in Figure 2, the mud of (illustrating regional A) can not be splashed to screen box outer (diagram area B) in the screen box.
Fig. 3 shows the structural representation that first cover plate according to an embodiment of the invention is connected with second cover plate.As shown in Figure 3, said first cover plate 21 is wider than screen box 4, covers on pivoted arm beam 13.Also be rotatably connected to second cover plate (minor flaps) 22 on said first cover plate (large cover) 21.The width of said second cover plate 22 is less than the inner width of screen box 4, and the inner width of being convenient to present embodiment is meant the distance of screen box 4 both sides inwalls.Said second cover plate, 22 cantilevers connect first cover plate, 21 end faces, and lid is gone in the screen box, avoids interfering with the motor cabinet installing plate 28 of screen box 4 both sides.At said first cover plate 21 and second cover plate 22 all is circular arc, and the end face that specifically refers to first cover plate 21 as shown in Figure 3 and second cover plate 22 is a cambered surface.
Fig. 4 shows first cover plate and the second cover plate rollover states sketch map according to an embodiment of the invention.The fixed support 3 that do not draw among Fig. 4, as shown in Figure 4, all be provided with handle 23 on said first cover plate 21 and second cover plate 22.Pull handle 23, the second cover plates (minor flaps) 22 can rotate around the 3rd hinge 25, thereby are turned on the large cover 21.
Fig. 5 shows first cover plate and the second cover plate rollover states sketch map in accordance with another embodiment of the present invention.The fixed support 3 that do not draw among Fig. 5, as shown in Figure 5, first cover plate (large cover) 21 can with second cover plate (minor flaps) 22 together, rotate around second hinge 24, overturn 90 °.Hydraulic pressure strut 27 is connected top rail 11 and first cover plate (large cover) between 21.Dug first cover plate (large cover) at 21 o'clock, hydraulic pressure strut 27 plays the power-assisted effect; Dig after first cover plate (large cover) 21, hydraulic pressure strut 27 works to prevent that its accident from falling down.
Said screen box 4 also is connected with mud box 2.Mud box 2 is used for supplying with the drilling fluid that needs processing to screen box.
