Abstract
Depth encoder is a kind of measurement apparatus determining sampling head sampling depth, its feature: utilizes the rope traction being fixed on sampling head elevating mechanism to drive sensing chip to rotate, measures sampling head height coordinate by the inductive impulse of proximity switch.It is applicable to sampling depth during vehicle transport loose unpacked material automatic sampling control.Using for many years it was verified that present configuration is simple, energy consumption is low, easy to manufacture, easy to maintenance, reliable, precise control, and the sampling depth being adapted to various transporting bulk material vehicle is measured.
Description
Technical field
The sampling head using hydraulic jack lifting is gathering coal, fine granularity or powdery admittedly
In the compartment of body material sample during stochastical sampling, the degree of depth accurately controlling sampling head is needed to sit
Scale value, depth encoder is exclusively for automatically obtaining sampling depth point design accurately.
Background technology
In automatic sampling process, in order to make materials in carriage arbitrfary point have the sampling of equalization
Probability, it is necessary to accurately control the descending stroke of sampling head, generally uses and controls hoist cylinder
Fall time, as sampling depth offset variable, controls the descending stroke of sampling head, therefore
There is following problems: 1. when sampling head runs into bulk materials stopping decline, under sampling head
Fall does not reaches the position of preset, causes deep material to be adopted less than sample;2. identical
Under thrust, due to the different speed causing sampling head to decline of humidity, granularity and the density of material
Degree difference, sampling head variate-value fall time is difficult to determine.
Summary of the invention
The aiming to overcome that the deficiencies in the prior art of patent of the present invention and provide a kind of accurately
Control the depth encoder of the descending stroke of sampling head.
The purpose of patent of the present invention is achieved in that depth encoder uses a moment
Motor 6, its stator is fixed by screws on support 1, and its rotor of output shaft axle passes through key
Coupling with the axis hole of rope sheave 5, the axis hole other end of rope sheave 5 is by key and jackshaft 3
Connecing, jackshaft 3 is supported on bearing block 2 by bearing 10, and bearing block 2 passes through bolt
Being fixed on support 1, support 1 is bolted on the top of sampling head frame;Electricity
Magnet clutch 9 is coupled with jackshaft 3 by key;Bolt is passed through in electromagnetic clutch 9 end
On fixed bearing block 2;One end of steel wire rope 8 is fixed on the former of rope sheave 5, another
End is walked around rope sheave 5 and is connected with the motion of sampling head;Sensing chip 4 is solid by screw
It is scheduled on rope sheave 5 side;Proximity switch 7 is fixed on support 1.When sampling head declines,
Torque motor 6 and electromagnetic clutch 9 simultaneously electric, electromagnetic clutch 9 declutches, steel
Cord 8 traction sheave 5 and torque motor 6 rotate clockwise, and are revolved by sensing chip 4
Turn, proximity switch 7 output pulse signal;The control system of sampling head is close by controlling
Switch 7 output pulse signal quantity and reach to control the stroke of sampling head;When sampling head rises
Time, torque motor 6 and electromagnetic clutch 9 simultaneously electric, electromagnetic clutch 9 declutches,
Torque motor 6 rotates counterclockwise, and steel wire rope 8 is regained and is wrapped on rope sheave 5.
When sampling head stops lifting, electromagnetic clutch 9 and torque motor 6 power-off simultaneously,
The brake(-holder) block braking of electromagnetic clutch 9, rope sheave 5 stops operating.
Sampling is controlled owing to using above-mentioned offset variable technology to avoid employing time variable
Head decline exist deficiency, reached materials in carriage arbitrfary point have equalization sampling several
The purpose of rate, is proved by application practice for many years, uses depth encoder to control sampling
Head descending stroke, accurate positioning, respond well.
