The discharge port of third conveying section 4 docked with the feed inlet of the 4th conveying section 5 and can around common axis (axis is perpendicular
Histogram to) relative rotation, i.e. the 4th conveying section 5 can be rotated in the horizontal plane centered on the feed inlet of itself.Third conveying
The junction of the feed inlet of the discharge port and the 4th conveying section 5 of section 4 is known as node C29.
Discharging coaster 13 is connected on discharge port on 4th conveying section 5, discharging 13 position of coaster is known as node
D30.5th conveying section 6 is obliquely installed, the feed inlet of the 5th conveying section 6 be located at the discharging coaster 13 just under
Side, discharging coaster 13 can not connect with the feed inlet of the 5th conveying section 6, can also be connected by flexible connection structures such as corrugated flexible hoses
It connects, the discharge port of the 5th conveying section 6 is directed toward the conveying terminal of material, i.e. material transfer vehicle (tank car etc.).
In said structure, between the discharge port of the second conveying section 3 and the feed inlet of third conveying section 4, third conveying section 4
Discharge port and the 4th conveying section 5 feed inlet and discharge port on the 4th conveying section 5 and discharging coaster 13 between can adopt
It is attached with pivoting support structure.Pivoting support is a kind of large size bearing for being able to bear combined load, can be born simultaneously
Biggish axial direction, radial load and tilting moment.
Three slideways, respectively the first slideway 14, the second slideway and third slideway 12 are provided in the rack 8, the
The shape of one slideway 14 is one section of circular arc using the node A27 as the center of circle, and the node B28 is transported along the first slideway 14
Dynamic, second slideway includes 11 two sections of circle segment 10 and linear section, and the shape of the circle segment 10 is
Using the distal end of the first slideway 14 as one section of circular arc in the center of circle, the node C29 is moved along the second slideway, the third slideway
12 shape is straight line, and the node D30 is moved along third slideway 12.It is all provided on first slideway 14 and the second slideway
It is equipped with chain 15 and driving coaster 16, chain 15 operates under the drive of the motor, driving lower edge of the driving coaster 16 in chain 15
Place slideway movement, to be moved with node B28 and node C29.
The rack 8 is installed on one group of parallel guide rail 9, and the power that rack 8 is advanced on the rail 9 is provided by motor.
The present invention joins end to end the second conveying section 3, third conveying section 4 and the 4th conveying section 5, forms "the" shape
Telescoping mechanism.Position as shown in Figure 2 is the initial state before the stretching, extension of "the" shape telescoping mechanism, at this point, node B28 is located at the
The distalmost end of one slideway 14, node C29 are located at the left end of the circle segment 10 on the second slideway.
"the" shape telescoping mechanism is divided into two steps by the process that initial state extends to longest state：
Step 1, circle segment 10 of the node C30 on the second slideway of drive lower edge of the driving coaster 16 moves,
Reach position as shown in Figure 3；
Step 2, node B29 is moved in the first slideway of drive lower edge 14 of the driving coaster 16, is reached as shown in Figure 4
Position, complete stretching, extension.
It, can be in the circle segment 10 and linear section 11 on the second slideway in order to make two above-mentioned smooth linkings of step
Limit switch is arranged in joining place, triggers limit switch after the completion of step 1, then the motor of driving node C30 stops, driving node
The electric motor starting of B29.
It should be noted that driving coaster 16 on second slideway moved to by the circle segment 10 it is described
Linear section 11 during, when drive coaster 16 move to the joining place of circle segment 10 and linear section 11 when, driving slide
16 stop motion of vehicle, node C29 and driving coaster 16 are detached from.I.e. node C29 is in no beam during above-mentioned step 2
The free state tied up.This design can not only make step 1 and step 2 be connected more smooth, and can avoid node B28 and node
The driving force of C29 interferes.
Helical blade 21 is provided in the scraper bowl 1, the material entered in scraper bowl 1 is delivered to scraper bowl by helical blade 21
1 middle part, is then delivered in the first conveying section 2 by the screw conveyor shaft 23 on the first conveying section 2 again.The edge of helical blade 21
Settable dentalation, consequently facilitating being conveyed to material.
The scraper bowl 1 is retractable structure.Scraper bowl 1 is designed to stretching structure, there are two benefits：First is that scraper bowl 1 can
Adapt to container of different size；Second is that when the position of the stand of container car 7 and scraper bowl 1 is there are when small range dislocation,
The position of two telescopic covers 19 can be adjusted separately, realizes " the whole sidesway " of 1 position of scraper bowl, thus not having to move container car
It normally unloads in the case where 7.
When it is implemented, scraper bowl 1 can be designed to such as flowering structure：Including main casing 18, outer housing 17 and telescopic cover 19, outside
Shell 17 is fixedly connected on the outside of main casing 18, and the telescopic cover 19 is inserted into the folder between main casing 18 and outer housing 17
In layer.There are two telescopic cover 19 is total, two telescopic covers 19 are separately positioned on the both ends of main casing 18, flexible by Driven by Hydraulic Cylinder
Cover 19 is mobile, it can be achieved that scraper bowl 1 stretches.
In order to cooperate the flexible of scraper bowl 1, the installation axle of the helical blade 21 is also retractable structure, and installation axle is divided into
Three sections, it is referred to as A shaft part 20, B axle section 24 and C shaft part 25, wherein the middle part of B axle section 24 is mounted on shovel by intermediate support 26
In bucket 1, the both ends of B axle section 24 are each provided with a hexagonal prisms 22, are provided on the A shaft part 20 and C shaft part 25 and institute
The matched six-edged axis set of hexagonal prisms 22 stated, A shaft part 20 and C shaft part 25 are sleeved on two hexagonal prisms 22 by six-edged axis set respectively
On with realize helical blade 21 installation axle it is flexible, the other end of A shaft part 20 and C shaft part 25 pass through bearing be connected to it is described
Telescopic cover 19 on.The installation axle of helical blade 21 uses retractable structure, and the width of the length and scraper bowl 1 that can make installation axle becomes
Change and keeps synchronizing.
In addition, for the ease of parking, the parking aid such as also settable parking position line and laser lamp.For the ease of behaviour
Make, remote controler can be used in the movement such as complete machine walking, scraper bowl 1 are gone up and down, scraper bowl 1 is flexible, hydraulic start and stop and the start and stop of each motor
Operation.
Present invention employs the stretching structures being formed by connecting by multiple conveying sections, and before work, container car 7 is parked in shovel
Struggle against 1 side, and is generally corresponding to the position of scraper bowl 1 and the position of container rear door, while material transfer vehicle being parked in
Below the discharge port of 5th conveying section 6.When work, rack 8 moves on the rail 9, to drive scraper bowl 1 continuous in container
It advances, completes the car unloading operation of container car 7, in 1 moving process of rack 8 and scraper bowl, by adjusting node B28 and node C29
Position on corresponding slideway can be such that the relative position on node D30 and ground remains unchanged, to guarantee unloading for container car 7
Process and the entrucking process of material transfer vehicle are carried out continuously.As it can be seen that the present invention overcomes the prior art by continuous car unloading operation
In the problem of unloading entrucking low efficiency, by unique conveying mechanism of the scraper bowl 1 in conjunction with screw conveyor, overcome unhandy
Problem overcomes the problem of material is easily scattered by totally enclosed feeding mechanism.Therefore, the present invention practical valence with higher
Value.
