Description
Technical field
The invention belongs to fields such as material loading, mining, driving, tunnel excavation, be specifically related to a kind of rolling rake material stowage and rolling rake material loader.
Background technology
The shipment of material such as adopt in order to solve big gun pick big gun, existing drive hoeing machine is made up of winch and entrucking groove, and the entrucking groove can be divided into dustpan mouth, rising chute and blowpit, and the rising chute plays guide effect to material.The dustpan mouth is then hinged with rising chute feed end, can it lifted or let-down ground through the adjustment lifting screw, and dustpan mouth front end is hinged with left baffle, can open or close.On the platform of rising chute rear end, winch is housed, winch is made up of motor, reduction box, reel, wire rope and scraper box etc.Directive wheel and slusher that the head rope of winch is walked around the blowpit rear end connect together, and tail rope is walked around the directive wheel of blowpit rear end, and fixedly rope sheave and the scraper box walked around on the face of meeting head on connect together again.Start winch, the scraper box that winch drives on the wire rope is taken off materials such as spoil or coal to blowpit through dustpan mouth, rising chute, is discharged into postorder transportation system from the discharge port of blowpit.
Take off the material machine adopts wire rope drive scraper box to get material more; Wire rope is the motion easy fracture in spoil; Wire cable rupture is prone to produce spark, and this is a danger close under coal mine, and therefore taking off the material machine does not meet the coal mine production safety requirement; But also do not have better substitute at present, is still using in a lot of collieries; Take off the material machine and only use a scraper box back and forth to take off charging, operating efficiency is very low; In addition, taking off needs fixedly rope sheave on the face of meeting head on of material machine, and wants manual work constantly to change the rope sheave position, causes very inconvenience of its use, and has reduced operating efficiency.
The star-wheel ground rotation of the crab claw of crab claw charger and star-wheel charger is parallel motion with respect to shovel plate and ground; Promptly get material from the side of material; Be prone to when the star-wheel that elevates above the soil, crab claw run into the earth bulge thing broken off with the fingers and thumb bad, so in the material shovel plane, get material, get the material scope little, act on little.
The hopper of taking off of the feeding device of rocking arm loader, armed lever loader and scoop loader is reciprocating type; Its inefficiency; Big, the armed lever length of taking up room is loaded difficulty in narrow, short tunnel big, takes off hopper and once feed transporter many and can not all transport, and takes off and expect to have lacked inefficiency; And charging is uneven, discontinuous, and is unfavorable to the postorder haulage device.
Rocking arm loader, armed lever loader and scoop loader and other various loaders are usually used in the loading of material, because its duty is reciprocating type, so efficiency of loading is low, power loading big, power consumption is big, and can not continuously and stably feeding.
Summary of the invention
The objective of the invention is to according to the mining driving; It is not of uniform size that institutes such as roadway excavation go out material piece grain; Weight does not wait; Material matter is different, unequal on-the-spot characteristics in ground and need give material and load, the rolling rake material loader that a kind of rolling rake material stowage is provided and implements this method in particular for coal mining, driving, tunnel excavation, material loading etc.
The present invention is that the technical scheme below adopting realizes: a kind of rolling rake material stowage; Wherein, this method makes full use of the characteristic of material gravity, and roller bearing and/or cylinder drive rake charging tooth spiral to be changeed; With the rake of rolling rake charge mechanism charging tooth from material top and/or upper lateral part insert; Continuously material is harrowed to material shovel and/or feeding unit, the rake that rolls of rolling rake charge mechanism is arranged at the front portion and/or the front upper of material shovel and/or feeding unit, and the material of rolling rake charge mechanism before to material shovel and/or feeding unit continuously measured clearly; Reduced the resistance that material shovel and/or feeding unit advance; Material shovel and/or conveying mechanism are advanced smoothly, and the reaction force of rake charging tooth quickens advancing of material shovel and/or feeding unit, and the support of rolling rake charge mechanism is arranged on material shovel and/or the feeding unit; The support of rolling rake charge mechanism makes to roll to harrow under the control of guiding mechanism and moves up and down; The material rake of the eminence that material shovel and/or feeding unit can't be touched needs bulk materials is brokenly used hammer tooth, axe tooth when broken, picks tooth and roll rake rake material and/or make and roll rake teeth and rotate at a high speed down, and super large piece material is broken broken and harrow to material shovel and/or feeding unit; The rolling rake charge mechanism matches with material, material shovel and/or feeding unit, need loaded material give the rapid Continuous transhipment.
The present invention also comprises a kind of rolling rake material loader of implementing said method, comprises material shovel and/or feeding unit, and material shovel and/or feeding unit comprise walking mechanism; Wherein, This rolling rake material loader also comprises the rolling rake charge mechanism, and the rolling rake charge mechanism comprises rolling harrows and support, and it is hinged to roll rake and support; Roll and harrow front portion and/or the front upper that is positioned at material shovel and/or feeding unit; Roll rake and comprise rake charging tooth, the length of rake charging tooth is not less than and needs 1/2nd of loaded material piece granularity, and support is arranged on material shovel and/or the feeding unit.
Described rolling rake charge mechanism comprises roller bearing tooth harrow loader.Roller bearing tooth harrow loader comprises roller bearing and/or cylinder, and the external surface of roller bearing or cylinder is provided with rake teeth.
