Abstract
The utility model provides a device which is applicable to belt conveyers to separate coal and waste rocks. By virtue of the device, coal and waste rocks can be separated from each other during transportation, so that the coal production quality is improved, and the washing workload is reduced. The device comprises a baffle hinged on a support and a baffle rotation power device which is used for driving the baffle to rotate and connected between the support and the baffle. When in the closed state, the baffle is positioned above the belt of the belt conveyer and is tilted to the belt moving direction (e.g. form an included angle of 30 degrees), so that waste rocks conveyed by the belt move along the baffle to leave the belt after being blocked by the baffle.
Description
Technical field
The utility model relates to a kind of coal and spoil disengagement gear, specifically, is to be applied on the belt transporter device that is separated with the coal that transports on the belt and spoil.
Background technology
According to statistics, coal road, half coal rock tunnel account for about 93% of China's coal-mine mine development end total amount, and its driving speed can directly influence normally taking over of mine production, simultaneously roadway maintenance and safety in production is also had a direct impact.The tunneling method of coal road and half coal rock tunnel has comprehensive mechanized driving method (be called for short and combine pick) and drill eye blasting drivage method (being called for short the big gun pick) usually.Though this several years China's coal-mine are combined the pick technology and obtained greatly developing, because the mine condition is limit, still adopt the big gun pick in a large number, the level of combining pick is also lower.Combining pick is exactly in the tunnel with the development machine driving, be equipped with equipment or systems such as reprinting transportation, dust removal by ventilation, supporting facility, assistant conveyance, measurement orientation, safety control, power supply, form a fully-mechanized digging machine tool equalization line, the driving system of form an efficient height, cooperatively interact, mechanization being produced.According to the difference of transportation device, the main type of fully-mechanized digging machine tool equalization line has: development machine-travelling apron operating line; Development machine-slat conveyer operating line; Development machine-shuttle car operating line; Development machine-mine car operating line.Preceding two kinds belong to continuous transportation, and transport capacity is big during with travelling apron, the production efficiency height; Can adapt to the condition that the tunnel slope change is big, length is short during with slat conveyer.Back two kind broken stowages, shuttle car and U.S.'s Joy's digger are used; Mine car uses at small mine or before conveyer fortune coal measures system does not build up.Big gun pick is exactly to drill and blast earlier, adopts rock rake to produce coal or spoil, after connect mine car and directly spoil transported.The mode that also has mine to adopt rock rake to match with travelling apron, and rock rake and belt feeder be split type, and belt feeder is placed on the subfacies that rock rake is steeved, and the coal on the rock rake is fallen on belt by leakage coal eye, and then it is transported.The big gun pick claims omnipotent driving technology again, and it can adapt to any geologic condition, has flexible, convenience, with low cost, and comformability is strong, can dig the advantages such as tunnel of Any shape, length.
In coal in China was produced, thin seam mining accounted for more than 50%, some thick coal-layer mining modernization mines, and along with the increasing of exploitation dynamics, the high seam reserves reduce gradually, will or turn to thin seam mining.In the crawlway developing, the big gun pick is even more important.The potentiality of big gun pick are very big, organize the rapid construction in big gun pick tunnel, and for keeping the normal relationn of excavation and recovering of mine, the stable and high yields of keeping mine is significant.
We know that in girdle alternate heading driving, coal is less, and spoil is more, in the big gun pick, generally coal and spoil are separated explosion, carry out the explosion and the shipment of coal earlier, carry out the explosion and the shipment of spoil again.Coal mix with rock transport by coal petrography loader, leather belt reshipment machine, belt transporter etc. after, coal does not separate with rock, causes that coal loads in mixture with spoil when loading, and reduces the quality of coal or the work capacity of increasing washing.
Summary of the invention
Of the present utility model provide a kind ofly be suitable on belt transporter using, the device so that coal is separated with spoil, coal is separated with spoil when transporting by this device, improved the quality of producing coal, reduced the work capacity of washing.
This coal and spoil disengagement gear comprise the baffle plate that is hinged on the support, and the baffle plate rotational power plant that drives the baffle plate rotation is connected between support and the baffle plate; When baffle plate was in closure state, baffle plate was positioned at the belt top of belt transporter, and baffle plate tilts (as becoming 30 ° of angles) with the belt moving direction and moves and from belt so that the spoil that transports on the belt is blocked afterwards along baffle plate by baffle plate.
After adding this coal and spoil disengagement gear on the belt transporter.When producing coal, baffle plate is opened and is allowed coal pass through together along the belt of belt transporter, thereby enters coal bunker.When going out spoil, handle baffle plate upset engine installation, baffle plate is in closure state, and spoil rushes down in the tunnel along baffle plate or in the mine car.This device realizes that coal separates when transporting with spoil, has avoided the loading in mixture in loading process because of coal and spoil, has improved the quality of coal, has reduced the work capacity of washing.
Above-mentioned coal and spoil disengagement gear, the baffle plate rotational power plant has varied, as adopting cylinder.
Above-mentioned coal and spoil disengagement gear, baffle plate become 0～30 ° of angle with the belt moving direction.
Description of drawings
Fig. 1 is the scheme drawing that coal and spoil disengagement gear are applied to belt transporter.
The specific embodiment
Referring to Fig. 1, coal and spoil disengagement gear 4 are installed in the middle part of belt transporter 3, and it comprises the baffle plate 42 that is hinged on the support 41, and it is hinged with support, baffle plate respectively to drive two baffle plate rotation cylinder 43 that baffle plate rotates.When baffle plate when normality (opening), baffle plate is positioned at the belt 31 sidepieces top of belt transporter, and parallel with belt.When baffle plate was in closure state, baffle plate was positioned at belt 31 tops of belt transporter, and baffle plate and belt 31 moving directions are inclined to 30 ° of angles, moved and from belt 31 along baffle plate so that the spoil that transports on the belt 31 is blocked the back by baffle plate.
In the big gun pick, coal and spoil are separated explosion, carry out the explosion and the shipment of coal earlier, again in the explosion of carrying out spoil and shipment.When producing coal, baffle plate is opened, and baffle plate is positioned at the belt sidepiece top of belt transporter, and baffle plate is parallel with the belt moving direction, allows coal pass through together along belt 31, thereby enters coal bunker.When going out spoil, handle baffle plate rotation cylinder 43, make flapper closure, baffle plate is positioned at the belt top of belt transporter, and baffle plate becomes 30 ° of angles with the belt moving direction.The spoil that transports on the belt is blocked the back by baffle plate and rushes down in the tunnel or in the mine car along baffle plate.
Present embodiment realizes that coal and spoil separate when transportation, avoided because of coal and spoil loading in mixture in loading process to reduce the quality of coal or the work capacity of increasing washing.
