Automatic poking device for on-site ammonium nitrate fuel oil explosive mixed loading truck and working method of automatic poking device

Abstract

The invention discloses an automatic poking device for an on-site ammonium nitrate fuel oil explosive mixed loading truck. The automatic poking device comprises a first sensor for detecting whether materials are conveyed in a spiral conveying assembly, a second sensor for detecting whether materials exist in a stock bin, and hydraulic rod poking assemblies; the first sensor is installed in the spiral conveying assembly of the on-site ammonium nitrate fuel oil explosive mixed loading truck; the second sensor is installed at the upper end of the interior of the stock bin; and the multiple groups of hydraulic rod material poking assemblies are installed on the two sides of the stock bin. According to the automatic poking device, materials in the stock bin are monitored; the situation that due to material caking, discharging is difficult, and the material conveying efficiency is reduced is avoided; meanwhile, automatic material poking is achieved through the hydraulic rod material poking assemblies; the influence of material caking on material conveying is avoided; and potential safety hazards and increase of the production load of operators caused by manual material poking are avoided.

Description

technical field [0001] The invention relates to the technical field of material conveying for an on-site ammonium oil explosive mixed loading vehicle, in particular to an automatic feeding device for an on-site ammonium oil explosive mixed loading vehicle and a working method thereof. Background technique [0002] The on-site mixed explosives vehicle is a large-scale special operation vehicle commonly used in the mine blasting process. Porous granular ammonium nitrate, one of the main raw materials for on-site mixed ammonium oil explosives, has the physical characteristics of easy moisture absorption and agglomeration. In the existing technology, the arched structure is mainly broken by manual pounding: after the operator finds the shed material, he wears protective equipment and reaches the roof of the car, and uses aluminum brazing made of non-flammable materials to pound the material from the top to the bottom bucket to form a material leakage funnel, so as to ensure the ...

[0002] The on-site mixed explosives vehicle is a large-scale special operation vehicle commonly used in the mine blasting process. Porous granular ammonium nitrate, one of the main raw materials for on-site mixed ammonium oil explosives, has the physical characteristics of easy moisture absorption and agglomeration. In the existing technology, the arched structure is mainly broken by manual pounding: after the operator finds the shed material, he wears protective equipment and reaches the roof of the car, and uses aluminum brazing made of non-flammable materials to pound the material from the top to the bottom bucket to form a material leakage funnel, so as to ensure the fluidity of porous granular ammonium nitrate, and then ensure the normal ratio and stable quality of mixed products. Although manual pounding can break the arch structure, but when the agglomeration is serious, it is necessary to The operator has been standing on the top to carry out the pounding operation, which is labor-intensive. When the vehicle is moving, it needs to go up and down the roof frequently, which not only delays production, but also poses a safety hazard of falling from the roof.
