[0003] Such as: Patent No. CN200520030056.8 Electro-hydraulic push-pull dredger, Patent No. CN200520133586.5 Fan jet loosening machine, Patent No. CN201220131035.5 Coal bunker loosening machine, Patent No. CN201220154822.1 A raw coal bunker clearing and dredging machine, Patent No. CN201220662309.3 A loosening machine for silo clearing engineering, patent number CN201220667770.8 A loosening machine control system, patent number CN201220583201.5 A coal drop pipe with a coal cleaning device, patent number CN201920622027.2 Jaw type loosening machine, these equipments are mainly used to clear the blockage after the silo is blocked, some have added a material breaking detection device, a timing device, realized the automatic loosening function of material breaking, timing loosening function, and some scrapers have a reciprocating straight line The movement will continuously remove the cohesive coal seam on the wall of the coal bunker, so as to effectively avoid the shrinkage or blockage of the coal bunker leak. The above-mentioned scheme can only achieve the effect of automatic loosening of material breaking or blind operation of the loosening equipment. The shortcomings of the above-mentioned various equipment are that the running speed of the loosening machine cannot be adjusted according to the running speed of the material, the running resistance is large, the equipment is easily damaged, the power consumption of the equipment is large, and the conveyor loosens after the material is cut off and blocked, which affects the normal production, or When there is no blockage, the material is loosened at regular intervals, manual loosening, no detection of the material running situation, blind loosening, resulting in loss of loosening equipment and energy, and failure to detect and deal with possible blockages before the blockage occurs

Abstract
The invention discloses a hydraulic loosening machine and an intelligent detection method thereof. The hydraulic loosening machine comprises a hydraulic station, an oil pipe, a loosening oil cylinder, a dredger and an electric control system, wherein the hydraulic station comprises a motor, an oil pump, an electromagnetic directional valve, a pressure gauge, an overflow valve, an oil tank, an oil pipe, an oil filter and a liquid level meter, the electric control system comprises a control switch and an indicator lamp, the electric control system further comprises a controller and a motor electric control governor, one end of the motor electric control governor is connected with the motor, the other end of the motor electric control governor is connected with the controller, and the controller is connected with the electromagnetic directional valve, the control switch and the indicator lamp. The operation speed of the loosening machine can be adjusted according to the operation speed of materials, the loosening resistance is reduced, the operation condition of the materials is detected by controlling the operation of the hydraulic loosening machine, whether loosening is carried out or not is judged according to the detection result, material blockage is prevented, and a large amount of time and electric energy consumed for clearing blockage are reduced. The hydraulic loosening machine has the advantages of intelligent detection function, long service life, low energy consumption and high economic benefit.
Description
Technical field [0001] The present invention relates to the technical field of hydraulic loosening machines, and specifically means a hydraulic loosening machine and its intelligent detection method. Background technique [0002] The loose machine is widely used in electricity, metallurgy, mine, coal, cement, chemical and other industries. At present, the unloading material of the loose material conveying material in electricity, steel, coal, chemical, cement and other industries is generally: square, rectangular, circular shape, most of which are superior, small, more down The smaller the cross-sectional area of the material flow trainer. When the material is unloaded, the material is flowing from the upper and lower flow of material, the friction of the material and the material, the friction of the material and the wall wall, and the pressure of the material and the wall of the warehouse, hindering the material. Flow, making the material easily bonded on the wall wall, the m...
