Embodiment Construction

[0019] This embodiment is a device for online detection of the feeding speed of a primary hopper, including a mounting bracket 2, a supporting beam 12, a structured light scanner 11, a camera 10 and a connecting support plate. The installation bracket is fixed on the side of the primary hopper 13 through the installation base 16, anchor bolts 18 and connecting nuts 17, and a support beam 12 is installed on the upper side surface of the installation bracket 2 by connecting a support plate, and the support beam The centerline of the centerline is perpendicular to the centerline of the mounting bracket. Both the camera 10 and the structured light scanner 11 are fixed on the lower surface of the cantilever end of the support beam 12 through a mounting plate, and are respectively located at two ends of the mounting plate. The explosion-proof control box 1 is fixed on the outer surface of the mounting bracket. One end of the power line 7 and the data line 8 communicate with the cam...

Abstract

The invention discloses an online detection device for discharging speed of a primary hopper. A mounting bracket is fixedly arranged beside the primary hopper; a supporting cross beam is arranged on the surface of one side of the upper end of the mounting bracket through a connecting supporting plate, and the supporting cross beam can rotate by 180 degrees around the mounting bracket; a high-resolution camera and a structural light scanner are fixedly arranged on the lower surface of a cantilever end of the supporting cross beam through a mounting plate, and the high-resolution camera and thestructural light scanner are separately arranged at two ends of the mounting plate; an explosion-proof control box is fixedly arranged on the outer surface of the mounting bracket; and one end of a power line and one end of a data line communicate with the high-resolution camera and the structural light scanner, and the other end of the power line and the other end of the data line communicate with each port of the explosion-proof control box. By means of the device, automatic on-line detection of the primary hopper is achieved, the manual intervention is reduced, the discharging speed of theprimary hopper is accurately controlled, so that the medicine slurry is guaranteed to be poured in an optimal state and leveled in a combustion chamber, the air hole problem is avoided, and the stability of the product quality is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of solid rocket motor charging, and relates to an online detection device for a feeding speed of a primary hopper during the propellant pouring process. Background technique [0002] When pouring the large combustion chamber, the slurry is first turned over from the mixing pot to the primary hopper, then discharged from the primary hopper through the flower plate to the secondary hopper, and finally poured into the combustion chamber shell from the secondary hopper. The feeding speed refers to the single-hole flow rate from the primary hopper to the secondary hopper through the flower plate, which is a key parameter affecting the pouring quality of the combustion chamber. If the feeding speed is fast, the degassing effect is poor, on the contrary, it is beneficial to the degassing effect. On the surface, slow feeding speed is more conducive to complete degassing, but it will prolong the pouring cycle, chang...
