Abstract
The invention relates to a large coal pre-crushing device of a fully-mechanized mining face. The large coal pre-crushing device comprises a transfer conveyor reinforcing groove (3) and is characterized by comprising a crushing top cover (1), the crushing top cover (1) is arranged on the transfer conveyor reinforcing groove (3), and a crushing shaft group (2) is arranged on the crushing top cover (1) and is in transmission connection with a power system by a transmission mechanism. The large coal pre-crushing device of the fully-mechanized mining face can be comprehensively arranged between a discharging hole of transfer conveyor and an intermediate groove at a landing segment of the transfer conveyor and is used for pre-crushing large coal of the full-mechanized mining face, the large coal is prevented from being clamped at an entrance of the intermediate groove at the landing segment of the transfer conveyor to cause plugging and stopping, and the large coal pre-crushing device is simple to install and operate, overcomes the defect of production influence, has high efficiency, is safe and reliable, and is suitable for a harsh working environment for a long time.
Description
Technical field
The present invention relates to a kind of fully-mechanized mining working coarse coal precrushing device.
Background technology
Fast development along with domestic big-and-middle-sized colliery, applying of fully mechanized coal winning technology, in the medium-thickness seam recovery process, the obscission that often has the bulk coal cinder, because bulk coal cinder size is larger, cause the conveying equipment can't normal transport, particularly in the haulage gate elevating conveyor section of landing porch, have a strong impact on normal safety in production and the efficient in colliery.At present; when high-seam working face coarse coal occurs and is stuck in the elevating conveyor section of landing intermediate channel porch; after all adopting shutdown, carry out fragmentation by means of instruments such as manpower, pneumatic pick, crowbars, have the problems such as labor strength is large, production efficiency is low, poor stability.
Summary of the invention
The purpose of this invention is to provide a kind of simple to operate, fully-mechanized mining working coarse coal precrushing device that efficient is high, safe and reliable.
A kind of fully-mechanized mining working coarse coal precrushing device, comprise the elevating conveyor strengthening groove, its special feature is: also comprise the broken top cover that is installed on the described elevating conveyor strengthening groove, at this fragmentation top cover the broken shaft group is installed, this broken shaft group is in transmission connection by transmission mechanism and dynamical system.
Wherein dynamical system comprises the electric machine support that is installed on the broken top cover, at this electric machine support motor is installed, and this motor is in transmission connection by driving-belt and broken shaft group, is rotated fragmentation thereby drive the broken shaft group.
The present invention is a kind of fully-mechanized mining working coarse coal precrushing device; can integral installation between elevating conveyor unloading port and the elevating conveyor section of landing intermediate channel; carry out precrushing for the fully-mechanized mining working coarse coal; prevent that coarse coal is stuck in the elevating conveyor section of landing intermediate channel entrance and results in blockage and shut down; fitting operation is simple, has overcome the defective that impact is produced, and efficient is high; safe and reliable, be applicable to long-term abominable working environment.
Description of drawings
Accompanying drawing 1 is structural representation of the present invention;
Accompanying drawing 2 is the top view of Fig. 1.
The specific embodiment
As shown in Figure 1, the present invention is a kind of fully-mechanized mining working coarse coal precrushing device, comprise elevating conveyor strengthening groove 3, also comprise the broken top cover 1 that is installed on the described elevating conveyor strengthening groove 3, in this fragmentation top cover 1 broken shaft group 2 is installed, this broken shaft group 2 is in transmission connection by transmission mechanism and dynamical system.
Wherein dynamical system comprises the electric machine support 4 that is installed on the broken top cover 1, at this electric machine support 4 motor 5 is installed, and this motor 5 is in transmission connection by driving-belt and broken shaft group 2, is rotated fragmentation thereby drive broken shaft group 2.
Apparatus of the present invention comprise motor 5, electric machine support 4, be installed in small belt pulley 6, joined v-belt 7 on motor 5 output shafts, be installed in big belt pulley 8 on the broken shaft group 2 etc. forms dynamical system, motor 5 is installed on the broken top cover 1 by electric machine support 4, and the broken shaft group 2 on being installed in broken top cover 1 is installed on the elevating conveyor strengthening groove 3 jointly by broken top cover 1.Apparatus of the present invention integral installation is carried out precrushing for the fully-mechanized mining working coarse coal between elevating conveyor unloading port and the elevating conveyor section of landing intermediate channel, prevent that coarse coal is stuck in the elevating conveyor section of landing intermediate channel entrance and results in blockage and shut down.It is power source that apparatus of the present invention adopt motor 5, the general exchange of mine motor of generally using with the colliery, so the characteristics such as it is simple to have a fitting operation, and production efficiency is high, and is safe and reliable.
