Detailed description of the invention
Be further described the utility model below in conjunction with accompanying drawing, protection domain of the present utility model is not limited to the following stated:
As depicted in figs. 1 and 2, a kind of blast self-checking device, it comprises airduct 1, a lock airduct 2 is provided with in the middle part of described airduct 1, in described lock airduct 2, radial direction is provided with multiple lock wind sheet 3, the two ends of described lock wind sheet 3 are provided with branch sleeve 4, a rotating shaft 5 is set with in described branch sleeve 4, and branch sleeve 4 rotates together along with rotating shaft 5, described lock airduct 2 is arranged the sleeve pipe 6 installing rotating shaft 5, a seal cover 7 is all connected with in the end of sleeve pipe 6, wherein seal cover 7 is stretched out in the rotating shaft 5 of locking on the right side of airduct 2, and this rotating shaft 5 is all fixedly connected with a connecting piece 8, the other end of described brace 8 is all hinged with a plate 9, described connecting plate 9 lower end is positioned on a cam, described cam is connected with drive motors 10, described drive motors 10 is electrically connected with a controller, the discharge pipe of airduct 1 is provided with an arm 13, described arm 13 is connected with the termination of a tube connector 14, another termination of described tube connector 14 is connected with a Pressure testing instrument 15, described Pressure testing instrument 15 is electrically connected with controller, the blast recorded is passed to controller by Pressure testing instrument 15, controller controls drive motors 10 according to the size of blast and works, thus lock wind sheet 3 is rotated, thus the air quantity locking airduct 2 is changed, play the blast size of the discharge pipe regulating airduct 1.
In the present embodiment, be provided with a bearing 11 in described sleeve pipe 6, rotating shaft 5 is sleeved in bearing 11, arrange bearing 11 make between rotating shaft 5 and sleeve pipe 6 relatively rotate more light, frictional force diminishes, thus makes rotating shaft 5 wear extent little, extends the service life of rotating shaft 5.
In the present embodiment, described branch sleeve 4 is provided with internal spline, rotating shaft 5 is provided with the external splines coordinated with internal spline, by spline fitted, make between rotating shaft 5 and branch sleeve 4 easy to connect, and synchronism between the two can also be ensured.
