Specific embodiment
Illustrate specific embodiment of the present utility model with reference to the accompanying drawings and examples, but following embodiment only uses It is described in detail the utility model, does not limit the scope of the utility model in any way.
Embodiment 1: a kind of lifting scrapper conveyor is hinged on pillar 2 referring to Fig. 1-3, including hanger 1, pillar 2 and machine tail end And the scrapper conveyor main body 3 on hanger 1 is lifted on by rope, in Fig. 1, it is shown that scrapper conveyor main body 3 is according to ship storehouse 91 or 92 Different location two working conditions, in harbour, due to the difference of water level, ship storehouse is likely to be at the height in ship storehouse 91 or ship storehouse 92 Degree, it is therefore desirable to which scrapper conveyor main body can be gone up and down.In Fig. 1, hanger 1 is door shape column, and pillar 2 is used as hinged support, scrapper conveyor Main body 3, which is hung with hanger 1 by pulley, draws component 11 to connect, and pulley, which is hung, draws component 11 to include top sheave, lower sheave, wirerope, on Pulley is mounted on hanger 1, oblique pull column 32 is equipped in scrapper conveyor main body 3, the crosspoint of these oblique pull columns 32 is connected with downslide Wheel, wirerope one end is fixed on hanger, and pile warp lower sheave, lower sheave, the other end are fixed on hoist engine.Pass through hoist engine Folding and unfolding wirerope, to control the length of wirerope.
Referring to Fig. 1-3, scrapper conveyor main body 3 includes frame body 31, inverted trapezoidal chute 33, double center chain type conveying assembly 34, gathers materials Device 35, tensioning apparatus 36 and roller 37.
Tensioning apparatus 36 includes the fixing seat for being mounted on 3 machine tail end of scrapper conveyor main body and the fixed length being mounted in fixing seat Plate, along the length direction of fixed length plate, on fixed length plate on open up multiple threaded holes, threaded hole is equally offered in fixing seat, Behind the relative position of adjustment fixed length plate and fixing seat, fixing seat and the fixation of fixed length plate can be realized by adjusting scraper plate by bolt The effect of 3 length of owner's body.
The double center chain 341 of double center chain type conveying assembly 34 including belt scraping plate, be arranged in scrapper conveyor main body 3 machine tail end the Second double center chain wheel 343 of one double center chain wheel 342 and the head end that scrapper conveyor main body 3 is set;First double center chain wheel, 342 pivot It is connected to the end of the fixed length plate of tensioning apparatus 36, and is fixedly connected by tensioning apparatus 36 with scrapper conveyor main body 3, it is double in first The distance of slot bottom of the axis of sprocket wheel 342 away from inverted trapezoidal chute 33 >=first double center chain wheel 342 effective radius;Roller 37 is arranged It at the head end of scrapper conveyor main body 3, and is articulated on frame body 31, and roller 37 and the slot bottom distance > of inverted trapezoidal chute 33 are rolled The radius of cylinder 37, inverted trapezoidal chute 33 are extended with the conveying guiding face of arc in the top of roller 37;Second double center chain wheel 343 is set The inside of lower section in frame body 31, roller 37 is set, and is articulated on frame body 31, the second double center chain wheel 343 is defeated with power motor Shaft transmission connection.Such as Fig. 3, the double center chain 341 of belt scraping plate includes left loop chain 3411, right loop chain 3412, scraper plate 3413, Zuo Huanlian 3411 and right loop chain 3412 it is isometric, and be sleeved on the first double center chain wheel 342, the second double center chain wheel 343 and roller 37, inverted trapezoidal and slip On the anchor ring that slot 33 is formed, scraper plate 3413 is fixed with left loop chain 3411 and 3413 knot of right loop chain, and multiple scraper plates 3413 are equidistant Setting on left loop chain 3411.The effect of conveying guiding face is that the double center chain 341 of belt scraping plate is avoided to be detached from inverted trapezoidal chute It is overlapped on after 33 on roller 37, the reason is that, when scrapper conveyor main body 3 is faced upward, if not conveying guiding face, material may be from Gap between roller and inverted trapezoidal chute 33 is slid down, to cause chain-drive section stuck.
Material-gathering device 35 is articulated in the head end of frame body 31, and is equipped with the gap that tolerant material passes through with the surface of roller 37; Material-gathering device is selected as bottom end and gathers materials steel pipe with the rectangle of necking, is provided in the side for the steel pipe that gathers materials for accommodating opening for rack Mouthful.The rectangle of selection pivot joint is gathered materials steel pipe, is faced upward in scrapper conveyor main body 3 or during nutation, due to gravity, material-gathering device 35 The angle with frame body 31 can be adjusted, keeps the dropping place of material more accurate.
In use, with the tail drive-connecting shaft (i.e. the articulated shaft of scrapper conveyor main body 3 and column 1) of scrapper conveyor main body 3 for angle point, In the state of facing upward of scrapper conveyor main body 3, vertical angle≤18 ° of conveyor surface, in the nutation state of scrapper conveyor main body 3, conveying The lower angle of depression >=-25 ° in face.
As needed, transfer feed bin 4 can also be set up, transfer feed bin 4 is arranged in above the machine tail end of scrapper conveyor main body 3, So that scrapper conveyor main body 3 can accept the material fallen from transfer feed bin 4;In Fig. 1, transfer feed bin 4 and scrapper conveyor main body 3 it Between connected by transfer conveyer 5, transfer feed bin 4 is arranged in above the machine tail end of transfer conveyer 5, the machine of transfer conveyer 5 Head end is arranged in above the machine tail end of scrapper conveyor main body 3.Transfer feed bin 4 and transfer conveyer 5 are consolidated with what is be placed on the ground Determine frame to be bolted.
Referring to Fig. 1, the course of work is: according to the position in ship storehouse, by controlling hoist engine folding and unfolding wirerope, with sliding in adjustment Wheel is at a distance from lower sheave, during adjusting top sheave at a distance from lower sheave, since one end of scrapper conveyor main body 3 is hinged on On pillar 2, the adjustment to the elevation angle of scrapper conveyor main body 3 is completed, during 3 elevation angle of scrapper conveyor main body adjusts, material-gathering device 35 Because gravity voluntarily adjust with the angle of frame body 31, keep it to be overlapped with vertical line with the cylinder heart, after scrapper conveyor main body 3 is adjusted in place, Material is unloaded in transfer feed bin 4, can guarantee the lasting handling of material in this way, material is transported to by transfer conveyer 5 and is scraped In trigger main body 3.In scrapper conveyor main body 3, if meeting Laws of Mechanics when material conveying operation at this time in the position in ship storehouse 92, If in the position in ship storehouse 91, at this point, mainly making scraper plate 3413 drives material uplink, since conveyor surface is inverted trapezoidal chute, material It can't be stuck between loop chain and chute side wall.At head, conveying guiding face has been obstructed between inverted trapezoidal chute and roller Down suction, material will not be fallen between inverted trapezoidal chute and roller, cause the situation that machine is stuck.And the surface of roller is Smooth surface, material will not be stuck between loop chain and roller.
The utility model is described in detail above in conjunction with drawings and examples, still, the skill of technical field Art personnel, can also be to each specific in above-described embodiment it is understood that without departing from the purpose of the present invention Parameter changes, and forms multiple specific embodiments, is the common variation range of the utility model, no longer detailed one by one herein It states.
