Embodiment Construction

[0026] This embodiment is a weighing hopper device for fine materials, including a vehicle frame 2 , a hopper 4 , a flap 6 , and a blade-type swing cylinder 8 .

[0027] Such as figure 1 As shown, the vehicle frame 2 is a carrier, and the hopper 4 is located on the vehicle frame 2 and fastened with bolts. The air hammer 3 is installed symmetrically on the outer peripheral surface of the small diameter end of the cone section of the hopper 4 . The small-diameter end of the hopper 4 and the straight section are connected together by bolts through flanges. The two ends of the two rotating shafts 9 are respectively installed in two symmetrical through holes on the barrel of the straight barrel section of the hopper 4 through the bushings 7 . The two flaps in the flap valve 6 are located in the cylindrical body of the straight section of the cylindrical body 4, and are respectively sleeved on the rotating shaft 9. The centerlines of the two rotating shafts are parallel to each o...

Abstract

The invention discloses a fine material weighing hopper device. The fine material weighing hopper device is characterized in that an electric positioner drives two vane oscillating cylinders to rotate, two turning plates are further driven to rotate to reach horizontal positions to so as block fine materials, and the fine materials flow through lower middle through holes and can be automatically weighed by explosion-proof on-ground electronic scales; the turning plates are opened by certain angles after the fine materials are weighed, so that the fine materials can be discharged into a fine material conveying hopper, the discharging speed can be increased under the impact effect of an air hammer in a discharging procedure, and then the fine material conveying hopper is transported to the position corresponding to a next working procedure. The fine material weighing hopper device has the advantages that the turning plates are accurate and reliable in opening and closing actions, weighing errors are few, and the fine material weighing hopper device can be applied to weighing and feeding operation on similarly powdery materials; the fine materials can be automatically weighed and can be automatically fed into the fine material conveying hopper, so that the shortcoming of troublesome labor required by manual carrying and feeding can be overcome, an intermediate link for loading fine materials into cloth bags can be omitted, and a phenomenon of inaccuracy in weighing due to the fact that the fine materials are attached to the cloth bags can be completely eradicated.

Description

technical field [0001] The invention belongs to the technical field of solid rocket motors, and relates to a fine material weighing and unloading device. Background technique [0002] Fine oxidizer is one of the important components in solid motor propellant, which plays a vital role in the burning rate of the motor. After the fine oxidant is sieved and weighed, it needs to be transported to the propellant mixing process for mixing operation. [0003] The existing technology is to put the sieved fine oxidant into a cloth bag for weighing, and then pour the fine oxidant in the cloth bag into the fine material transport hopper, and then send the fine material transport hopper to the propellant mixing The process carries out the mixing operation of the propellant. [0004] The existing technical operation process is backward, and a part of the oxidant in the cloth bag always adheres to the cloth bag, and cannot be completely added into the fine material transport hopper. The...
