Problems solved by technology

[0002] The existing metering methods of porous granular ammonium oil explosive mixed trucks are all spiral metering, which belongs to the metering in the physical sense. The magnetic sensor measures the number of spiral rotations, and finally the system calculates the output of the material. The error is within 5% of the theoretical data. The error is relatively large, and the measurement is unstable, which affects the amount of charge at the blasting site and ultimately affects the quality of the blasting project. The screw conveying is unstable, and the material is likely to be a few kilograms more at the moment of the last stop in the conveying process, which brings great trouble to the blasting charge

Embodiment Construction

[0019] The high-precision porous granular ammonium explosive on-site mixed loading vehicle delivery metering system 15 of the present invention uses a belt conveyor. The belt conveyor is provided with a shell to form a fully enclosed belt conveyor. The material is all stainless steel (304 material) to improve the intrinsic safety. The side screw 9 of the metering system 15 and the on-site mixed loading vehicle 14 for porous granular ammonium explosives (hereinafter referred to as the mixed loading vehicle) is suspended on the left side of the mixed loading vehicle 14 (the vehicle is moving in the forward direction) through a suspension bracket 10 and steel pins. Ammonium nitrate and diesel fuel are mixed with the side screw 9 of the mixing truck 14 and then lifted to the discharge port 16 of the side screw 9 of the mixing truck and then transported to the metering system 15.

Abstract

The invention relates to a metering device of a multi-hole granular ammonium nitrate fuel oil mixture site mixed-loading vehicle, and belongs to material metering devices. A casing is arranged on a belt conveyor so as to form a fully closed belt conveyor, and the belt conveyor adopts skirt belts. At least two weighing sensors are mounted on carrier rollers of the fully closed belt conveyor, and the weighing sensors are respectively connected with a calculation display meter through signal lines. The metering device uses the belts to measure, materials can maintain a stable conveying state by using the belts to convey, convenience is brought for precise metering, all materials on the belts of the fully closed belt conveyor can be measured completely, and stability and accuracy of the materials during transportation are improved. A speed sensor can accurately measure the speed of material conveying by the belts, namely, the amount of the materials passing through a pressure sensor within unit time, and finally, an accurate metering result is obtained through meter calculation.

Description

Technical field: [0001] The invention relates to a high-precision porous granular ammonium explosive on-site mixed loading vehicle conveying and metering system, which belongs to a material metering device. Background technique: [0002] The existing measurement methods of the porous granular ammonium explosive mixed loading vehicle are all spiral measurement, which belongs to the physical meaning of the measurement. The principle is to measure the weight of the material pushed out by a spiral rotation in advance, and the weight is set on the spiral tail and the spiral bracket. The magnetic sensor measures the number of spiral rotations, and finally the system calculates the output of the material. The theoretical error data is within 5%, the error is large, and the measurement is unstable, which affects the charge at the blasting site and ultimately affects the quality of the blasting project. Spiral conveying is unstable, and the material is easy to add a few kilograms at the l...
