Description
Technical field
The utility model belongs to metallurgical technology field, relates to a kind of belt head portion automatic sampler being applied to enrichment plant specifically.
Background technology
In the prior art, mine ore sample takes the mode of hand sampling usually.In actual mechanical process, sampling workman intercepts a certain amount of ore sample with sampling shovel at set intervals on belt transporter, then carries out mixing, division.
But because sampling operation frequency is higher, hand sampling mode can waste a large amount of manpowers, and easily there is potential safety hazard in hand sampling process.Meanwhile, in hand sampling operating process, the human elements such as sampling interval time, sampling operation standardized degree all directly can have influence on sampling result, and human element usually can cause ore sample not representative.
For avoiding human element to affect sampling result, alleviating labor strength, eliminating the potential safety hazard of hand sampling process simultaneously, in prior art, adopting automatic sampler to complete above sampling work.But the usual complicated structure of existing automatic sampler, cost is higher, is not easy to install.Therefore, be necessary to develop the more simple automatic sampler of a kind of structure.
Utility model content
The deficiency that the utility model exists to overcome prior art, provides a kind of structure more simple belt head portion automatic sampler.
The utility model is achieved through the following technical solutions: a kind of belt head portion automatic sampler, comprise raw ore belt transporter, electric drive hydraulic thruster above the side being arranged at raw ore belt transporter end, be arranged at the sampling bag immediately below electric drive hydraulic thruster and be obliquely installed the sampling elephant trunk between raw ore belt transporter end and sampling bag, hinged with a support in the middle part of the lower end of described sampling elephant trunk, described sampling bag is positioned at the side-lower of described raw ore belt transporter end, on the left-half of the described sampling elephant trunk position between described electric drive hydraulic thruster and described sampling bag, the left-half of described sampling elephant trunk and the piston rod to downward-extension of described electric drive hydraulic thruster hinged, the left port of sampling elephant trunk is just to described sampling bag, the right part of described sampling elephant trunk is positioned at the side of described raw ore belt transporter end, during non-sampling state, the piston rod of described electric drive hydraulic thruster stretches out downwards, and piston rod pushes away the left-half of sampling elephant trunk downwards, and the end of described raw ore belt transporter is left in the right part of sampling elephant trunk, during sampling state, the piston rod of described electric drive hydraulic thruster is upwards regained, and piston rod upwards mentions the left-half of sampling elephant trunk, and the right part of sampling elephant trunk touches the end of described raw ore belt transporter.
The piston rod side of described electric drive hydraulic thruster corresponds to the upper of sampling state lower piston rod recovery and bit positions is provided with magnetic limit switch, and piston rod corresponds to magnetic limit switch and is provided with magnet piece.
The beneficial effects of the utility model are: the utility model is applied to muck workshop section, the automatic sampling of raw ore belt of belt conveyor head ore can be realized, do not need manual intervention, hand sampling can be replaced preferably, completely avoid the impact of human element, improve raw ore sample representativeness.Meanwhile, the utility model also can work on long-time continuous stable ground, eliminates the potential safety hazard in hand sampling process, alleviates labor strength, for controlling impoverishment rate in mining, instructing selecting and purchasing to produce, provide failure-free data basis.The utility model structure is more simple, and compare other automatic samplers on market, its cost is lower.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
As Figure 1-3, a kind of belt head portion automatic sampler, comprise raw ore belt transporter 4, electric drive hydraulic thruster above the side being arranged at raw ore belt transporter 4 end, the sampling elephant trunk 2 being arranged at the sampling bag 3 immediately below electric drive hydraulic thruster and being obliquely installed between raw ore belt transporter 4 end and sampling bag 3, hinged with a support in the middle part of the lower end of sampling elephant trunk 2, sampling bag 3 is positioned at the side-lower of raw ore belt transporter 4 end, on the position of left-half between electric drive hydraulic thruster and sampling bag 3 of sampling elephant trunk 2, the piston rod 1 to downward-extension of the sampling left-half of elephant trunk 2 and electric drive hydraulic thruster is hinged, the left port of sampling elephant trunk 2 is just to sampling bag 3, the right part of sampling elephant trunk 2 is positioned at the side of raw ore belt transporter 4 end, during non-sampling state, the piston rod 1 of electric drive hydraulic thruster stretches out downwards, and piston rod 1 pushes away the left-half of sampling elephant trunk 2 downwards, and the end of raw ore belt transporter 4 is left in the right part of sampling elephant trunk 2, during sampling state, the piston rod 1 of electric drive hydraulic thruster is upwards regained, and piston rod 1 upwards mentions the left-half of sampling elephant trunk 2, and the right part of sampling elephant trunk 2 touches the end of raw ore belt transporter 4.
Electric drive hydraulic thruster is connected with Hydraulic Station by oil circuit, and electric drive hydraulic thruster take electrical motor as propulsion source, by double-direction gearpump pressure oil output, through the control of oil-way integrated block, to oil cylinder, realizes the crank motion of piston rod 1.
Piston rod 1 side of electric drive hydraulic thruster corresponds to the upper of sampling state lower piston rod 1 recovery and bit positions is provided with magnetic limit switch, and piston rod 1 corresponds to magnetic limit switch and is provided with magnet piece.
Belt head portion automatic sampler also comprises Intelligent timer, annunciator, manual switchover knob and sampling switch.
The control logic of the utility model belt head portion automatic sampler is:
1, the control system of the utility model and raw ore belt transporter 4 realizes chain, and raw ore belt transporter 4 runs, and the utility model starts simultaneously, enters automatic running state.
2, adjustment arranges Intelligent timer, and Intelligent timer is according to the start and stop of prior setup control Hydraulic Station.
