Technical solution problem of the present invention adopts following technical scheme:
The constructional feature of baffle type crawler hoister of the present invention is that load-transfer device is supported on drive roll, driven cylinder, lower compression roller and the last pressure roller on the frame that is provided with by hoisting depth, and driven cylinder is positioned at the feeding end of load-transfer device; " C " font bearing material baffle plate evenly is set on described load-transfer device at interval, and feeder hopper is positioned at the feeding end top of load-transfer device, and discharge bucket is positioned at the discharge end below of load-transfer device.
Constructional feature of the present invention also is:
Described load-transfer device is set to section and is " C " font structure.
Described bearing material plate washer is an arc.
The cylinder surface of described drive roll adopts the cylindrical frame structure.
On described drive roll, driven cylinder and last pressure roller, along the excircle of cylinder annular concave path is set respectively, corresponding to the position at annular concave path place, on described load-transfer device, be set to and the convex tendon of described recessed road with concavo-convex scarf.
The material toggling cylinder is set in the discharging opening of described feeder hopper, radially switch-plate evenly is set on the excircle of material toggling cylinder, between material toggling cylinder and driven cylinder messenger chain is set, described messenger chain makes on the material toggling cylinder bearing material baffle plate on the switch-plate and load-transfer device with mode synchrodrive one to one.
Exit position at discharge bucket is provided with level detector, with the detection signal of level detector output as gig control signal out of service.
Compared with the prior art, beneficial effect of the present invention is embodied in:
1, belt transmission of the present invention, mass transport is steady, does not have relative motion between material and load-transfer device, can avoid the damage to transported substance.
2, the present invention's load-transfer device is set to section and is " C " font, is particularly suited for the conveying of bulk cargo, can effectively improve transport efficiency.
3, easy and simple to handle, easy to maintenance, the low energy consumption of the present invention, low noise, use cost are low.
4, the present invention is provided with the material toggling cylinder and is can reduce putty effectively to strip and sheet material etc. in feeder hopper.
5, the present invention can be at the opening or stop of concrete discharging situation control delivery system, and system is reliable.

Number in the figure: pressure roller, 6 drive rolls, 7 bunchers, 8 load-transfer devices, 9 materials, 10 discharge buckets, 11 level detectors, 12 material toggling rollers, 13 bearing material baffle plates, 14 annular concave paths, 15 convex tendons on 1 frame, 2 driven cylinders, 3 feeder hoppers, 4 lower compression rollers, 5.
The present invention is further described below in conjunction with drawings and Examples.
The specific embodiment
Referring to Fig. 1, Fig. 1 a, Fig. 1 b and Fig. 2, on the frame 1 of pressing the hoisting depth setting, load-transfer device 8 is supported on drive roll 6, driven cylinder 2, lower compression roller 4 and the last pressure roller 5, and driven cylinder 2 is positioned at the feeding end of load-transfer device 8; Bearing material baffle plate 13 is set on load-transfer device 8 at interval, and feeder hopper 3 is positioned at the feeding end top of load-transfer device 8, and discharge bucket 10 is positioned at the discharge end below of load-transfer device 8, and drive roll 6 is to drive with buncher 7.
In concrete the enforcement, the corresponding structure setting also comprises:
In order to increase gearing friction power, alleviate cylinder weight, the cylinder surface of drive roll 6 is set to the cylindrical frame structure; In order to increase the charge amount, prevent that material from falling, bearing material plate washer 13 is set to arc.
In order to prevent belt deflection, can be on drive roll 6, driven cylinder 2 and last pressure roller 5, excircle along cylinder is provided with annular concave path 14 respectively, position corresponding to 14 places, recessed road, on load-transfer device 8, be set to and the convex tendon 15 of recessed road 14 with concavo-convex scarf, convex tendon 15 is set to the strip convex tendon along the length direction of whole load-transfer device 8.
Material toggling cylinder 12 is set in the discharging opening of feeder hopper 3, radially switch-plate evenly is set on the excircle of material toggling cylinder 12, between material toggling cylinder 12 and driven cylinder 2, messenger chain is set, messenger chain makes on the material toggling cylinder 12 the bearing material baffle plate on the switch-plate and load-transfer device 8 with mode synchrodrive one to one, and material 9 falls within on the load-transfer device 8 synchronously through switch-plate radially.
In order to increase lifting capacity, load-transfer device 8 is set to section is " C " font structure, so that it is suitable for the lifting to bulk materials such as sheet, bulks more, improve transport efficiency.
In concrete the enforcement, level detector 11 can be set in the exit position of discharge bucket 10, occur at the discharging opening place piling up as material, out of service by level detector 11 detections and automatic guidance gig, send out up to the material of piling up.
