Detailed Description

The present invention will be further described with reference to fig. 1 to fig.

Horizontal elephant trunk power discharge apparatus includes tripper, discharge belt feeder. The discharging trolley comprises a driving wheel set 1, a driven wheel set 15, a frame 7, a guide rail 16 and a belt conveyor. The driving wheel set 1 comprises a driving chain wheel 4 and a driven chain wheel 2. The driving wheel set 1 and the driven wheel set 15 are arranged at the bottom of the frame 7 and are in sliding connection with the guide rail 16, and the driving chain wheel 4 is connected with the driven chain wheel 2 through the chain 3. The guide rail 16 for the trolley to run is erected on the frame of the discharge belt conveyor. The front half part of the frame 7 is a slope type feeding frame. The top of material loading frame fixed mounting has unloading cylinder 9, and the afterbody of frame 7 is the bin of unloading, and in the unloading bin, the feed inlet of discharge hopper 10 is connected with the discharge gate of unloading cylinder 9. A flat carrier roller 18 is fixedly arranged on the frame, a belt of the belt conveyor is sequentially wound on the feeding frame, the discharging roller 9 and the bend roller 17, and materials are conveyed to the discharging roller 9 through the belt conveyor.

The double-fork chute is used for solving the problems that the whole height and length of a frame of the unloading trolley are large, the overall dimensions of the frame in the length direction and the height direction are large, the weight is large, the power required by the walking of the unloading trolley is large, the power consumption is large and the like due to the fact that the unloading roller outlet of the original unloading trolley adopts the double-fork chute. Therefore, the original bifurcated elephant trunk is replaced by the horizontal elephant trunk, the horizontal elephant trunk 8 is of an inverted U-shaped hollow structure, the lower portion of the horizontal elephant trunk 8 is provided with a discharging opening, the top surface and two side surfaces of the horizontal elephant trunk 8 are provided with steel plates to form a guide chute, and the guide chute is connected with a flange on the lower side surface of the discharging hopper 10. The horizontal chute 8 is a channel for conveying materials to the outside, is a hanger (hanging beam) of a lower discharging belt conveyor, is a guide chute of the discharging belt conveyor, and has a three-purpose function.

In order to cooperate with the horizontal two directions of the horizontal chute to unload materials and expand the unloading range, two unloading belt conveyors are horizontally and symmetrically arranged at the bottom of the horizontal chute 8, and the running directions of the two unloading belt conveyors are opposite. The discharging belt conveyor is a broadband high-speed flat belt conveyor and is used for conveying materials conveyed by the discharging roller 9. In order to compress the whole height size of the whole device, a flat belt machine supporting frame and a material guide groove are not additionally designed and manufactured below a flat belt machine, and the flat belt machine is hung below a horizontal chute. In each belt conveyor, in order to convey materials away quickly and achieve the effects of no material accumulation and no material blockage, a driving device of the flat belt conveyor adopts a small-diameter high-rotating-speed electric roller.

When the device operates, materials enter the horizontal chute 8 through the discharge hopper 10, are dispersed at two ends of the horizontal chute 8, fall onto the two flat belts 11, and operate outwards on the belts through the rotation of the head electric roller 12 and the tail electric roller 13 until the materials at the head electric roller 12 are thrown out towards the outer sides of two sides, so that the whole process of material discharge is completed. The cycloidal pin gear speed reducer 5 drives the driving chain wheel 4, the driven chain wheel 2 and the driving wheel set 1 to realize the back-and-forth walking of the unloading vehicle and realize the double-side unloading while walking.

As can be seen from the above description, the device has the following advantages:

(1) the original branched chute with the inclined discharge trolley is designed into horizontal chutes on two sides, and then two discharge belt conveyors are used in a matched manner, so that the discharge range is wider. Because the horizontal elephant trunk has replaced the branching elephant trunk, can be so that the height of dummy car reduces to the focus of dummy car has been reduced, and make the dummy car operation more steady.

(2) The rotary unloading drop of the material between the unloading roller of the unloading trolley and the flat belt conveyor is small, the impact force of the material on the receiving part of the tail part of the flat belt conveyor belt is small, the abrasion on the flat belt conveyor belt is small, and the service life of the flat belt conveyor belt is prolonged.

(3) The flat belt machine head and the flat belt machine tail are both driven by small-diameter high-speed electric rollers, so that the belt speed is high, the fabric layer of the flat belt machine belt is very thin, the vertical force on a carrier roller is small, the material forms high-speed flat throwing motion at the head, the outward throwing distance is long, and the cross section of the horizontal chute is large due to the internal space, so that material accumulation and material blockage cannot be generated, the side wall abrasion is small, the maintenance workload is small, and the whole operation is stable, safe and reliable.

(4) The horizontal chute is used, so that the overall height and length of the discharge trolley are reduced, the material for manufacturing the trolley is saved, the manufacturing cost is reduced, and the utilization rate of a stockyard is greatly improved.

It should be understood that the detailed description of the utility model is merely illustrative of the utility model and is not intended to limit the utility model to the specific embodiments described. It will be appreciated by those skilled in the art that the present invention may be modified or substituted equally as well to achieve the same technical result; as long as the use requirements are met, the method is within the protection scope of the utility model.
