Abstract
The utility model relates to an injection air-control mine explosive loading machine which comprises an explosive barrel, an explosive loading part and an air control part, wherein, the air control part is provided with an air control valve and a manual valve so that one person can realize a middle range control and a long range control. The utility model has the advantages of simple operation and high work efficiency. The utility model is designed with a bulkhead vibration device, and the pneumatic vibration exciter of the main body of the utility model is arranged on the outer side surface of the bottom part of the explosive barrel. So the phenomenon of dilating stock is effectively eliminated, and the inner space of the explosive barrel is not occupied. The supporting legs of the explosive barrel are in three-point support, and each touchdown end is a tapered contact so that the work stability of the complete machine is enhanced.
Description
The utility model relates to the mining explosive loader of injecting type gas control that in mining blasting, uses.
In mining blasting, use the medicine in bulk of good fluidity to replace small medicine coil (or cartridge bag), not only can improve the degree of packing in the big gun hole, and then improve blasting efficiency, and can improve the labour intensity and the safety of powder charge.Mining explosive loader is answered the use of medicine in bulk and is occurred.The injecting type explosive loader is suitable for loading big gun hole, small-bore, and present domestic like product has BQ-20A type explosive loader, and it has simple in structure, in light weight, adopts the back of the body to shoulder formula and carries mode, also has convenient carrying.But this explosive loader generally needs two people operation owing to adopt the release mode of nearby exitting to control opening, stopping of powder charge process, has inconvenient operation, ineffective problem; And near empty bucket the time, easily produce swollen material phenomenon, particularly outstanding to viscous explosive; Simultaneously, adopt three stand bar structure, and the form of structure of leg and the mode of contacting to earth be board-like, have poor rigidity, stability is low, easily problem of slip.External like product for solving swollen material problem, is equipped with vibrator in explosive barrel inside, but has reduced the internal capacity of explosive barrel, and easily forms new discharging " dead band ".
The purpose of this utility model just provides the mining explosive loader of a kind of injecting type gas control, adopt one man operation just can realize in, Long-distance Control, easy and simple to handle, high efficiency can be eliminated swollen material phenomenon effectively simultaneously, and improve the job stability of complete machine.
The technical solution of the utility model is: comprise explosive barrel, charge segment and pneumatic control section, wherein pneumatic control partly is positioned on the air inlet pipeline, and main valve is that Pneumatic valve is positioned on the main gas circuit, and hand control valve is connected with Pneumatic valve with main gas circuit by pneumatic pipeline.
According to technique scheme, because the utility model has Pneumatic valve and hand control valve in the pneumatic control partial design, opening of whole system, stop controlling by a switch on the hand control valve, hand control valve is opened, high pressure gas in the main gas circuit is through pneumatic pipeline, hand control valve is to Pneumatic valve, Pneumatic valve is opened, provide high pressure gas to charge segment, can realize powder charge, close hand control valve, Pneumatic valve ends, and charge segment does not have high pressure gas and supplies with, stop powder charge, easy to operate, reliably, can carry out, far distance controlled, thus overcome borehole distance explosive loader distance unfavorable factor far away and that constantly change and problem such as be inconvenient to control, realize powder charge, control has improved operating efficiency by one man operation.
The utility model has also designed hopper wall vibrator, be made of pneumatic vibrator, and be contained in the exterior lateral sides of explosive barrel bottom, and pneumatic vibrator exports on the gas circuit that is connected with Pneumatic valve choke valve is housed.At the bottom of can passing to vibration barrel, pneumatic vibrator, eliminating the explosive wall sticking phenomenon, thereby solves swollen material problem effectively until whole explosive barrel, and particularly suitable to viscous explosive.Because pneumatic vibrator is the lateral surface that is contained in the explosive barrel bottom, rather than inner, thus the inner space of explosive barrel do not occupied, thus not influencing the explosive payload of explosive barrel, new discharging " dead band " can not appear yet.Simultaneously, the big I of the excitation parameter of vibrator is regulated arbitrarily by choke valve according to actual needs, therefore, its functional reliability height, adverse effect is by controlled to greatest extent.
The supporting leg of explosive barrel of the present utility model is supported at three point, and the end that respectively contacts to earth is conical contact tip.This mode of contacting to earth is particularly suitable for the ground of uneven double band dust deposit on stope or the cubic metre of earth and stone building site, has improved the job stability of complete machine.
Therefore, the mining explosive loader novel structure of the injecting type gas control that the utility model provides, reasonable in design, have simple, convenient, high efficiency, complete machine good operating stability, and can eliminate characteristics such as swollen material phenomenon effectively.
Describe in detail below in conjunction with the embodiment accompanying drawing.
At first accompanying drawing is described:
Fig. 1 represents structure chart of the present utility model;
Fig. 2 represents the gas control schematic diagram.
Referring to Fig. 1, comprise explosive barrel, charge segment, pneumatic control part and bulkhead vibrating device.Wherein explosive barrel comprises explosive barrel top 1, has parts such as support 2, the explosive barrel bottom 3 of braces and ground chain 7, and top 1 be last round inferior pyramidal, and bottom 3 is taper, and both connect by flange.Frame 2 is supported at three point, and the end that respectively contacts to earth is conical contact tip.Charge segment mainly is made up of parts such as nozzle 9, discharge nozzle 8, suction medicine joint 6 and grug transportation tubes 5, and drug discharging tube 8 is connected the bottom of explosive barrel.When gases at high pressure during by nozzle 9 ejection, around it, produce negative pressure, the explosive in the explosive barrel is sucked medicine joints 6 by discharge nozzle 8, then through the grug transportation tube 5 big gun hole of packing into.The pneumatic control part mainly is made up of gas control shutoff valve, hand control valve and gas connection pipe road and joint thereof, and it is Pneumatic valve 10 that main valve is housed on source of the gas sebific duct 13, and hand control valve 12 is connected with Pneumatic valve 10 with source of the gas sebific duct 13 by gas control sebific duct 11.The gas control principle is referring to shown in Figure 2, open hand control valve 12, small part of gas in the source of the gas sebific duct 13 arrives Pneumatic valve 10 through gas control sebific duct 11, hand control valve 12, open it, main gas in the source of the gas sebific duct 13 promptly enters nozzle 9 and ejection through Pneumatic valve 10, close hand control valve 12, Pneumatic valve 10 ends, and whole device is not worked.P, P ' expression source of the gas among the figure, A, A ' expression work gas circuit, O, O ' represent exhaust opening, K represents the control mouth.Hopper wall vibrator mainly is to be made of pneumatic vibrator 4, and is contained in the exterior lateral sides of explosive barrel bottom 3, and pneumatic vibrator 4 exports on the tracheae that is connected with Pneumatic valve 10 choke valve 14 is housed.Pneumatic valve 10 is opened when carrying out powder charge, and pneumatic vibrator 4 is vibration simultaneously under the effect of air-flow, and the big I of vibration is adjusted by choke valve 14.Pneumatic valve 10 is closed, and pneumatic vibrator 4 quits work simultaneously.
