[0033] Embodiment 1

[0034] like Figure 1-4 As shown, the utility model provides an automatic coal-flattening device for loading, comprising a suspension 1, a coal-flattening assembly installed on the inner side of the suspension 1, a linkage assembly arranged in the coal-flattening assembly, a lifting assembly installed on the rear side of the suspension 1, and a transmission assembly arranged in the lifting assembly.

[0035] The suspension 1 is arranged below the coal outlet, two guide beams 2 are symmetrically arranged along the front and rear center axis of the suspension 1, a guide groove 201 is opened in the guide beam 2 to communicate with the side of the guide beam 2 close to the front and rear center axis of the suspension 1, and two ends of the connecting guide block 5 can only slide in the guide groove 201 along the opening direction of the guide groove 201, and the flat coal motor 4 is connected by bolts on the front side of one guide beam 2, so that the output shaft of the flat coal motor 4 passes through the guide groove 201 from the front side of the guide beam 2, and the flat coal motor 4 is fixedly connected to the output shaft of the flat coal motor 4 and the flat coal motor 4 is threadedly connected to one end of the guide block 5 The screw 401 allows the coal-leveling motor 4 to be started through a positive and reverse cycle to drive the coal-leveling screw 401 to rotate when the coal is loaded, thereby driving the guide block 5 which is threadedly connected to the coal-leveling screw 401 and can only slide along the direction in which the guide groove 201 is opened to reciprocate, so that the guide block 5 can contact the top surface of the coal transport vehicle, thereby smoothing the coal accumulation that exceeds the bucket, and then pushing the smoothed coal to the empty space in the bucket, so that the bucket can be loaded with more coal, and the top of the accumulation can be prevented from exceeding the top of the bucket, thereby preventing the coal from leaking from the bucket during transportation.

[0036] By setting the coal-leveling screw 401 as a reciprocating screw, the guide block 5 can automatically enter the reverse thread when it moves to the end of the coal-leveling screw 401, so that there is no need to frequently start the coal-leveling motor 4 forward and reverse to drive the guide block 5 to reciprocate. By reducing the number of starts and stops of the coal-leveling motor 4, the service life of the coal-leveling motor 4 is improved.

[0037] Furthermore, by setting two coal-leveling screws 401, the two coal-leveling screws 401 are symmetrically arranged in the guide groove 201 along the front and rear center axes of the suspension 1, and the two coal-leveling screws 401 are respectively threadedly connected to the two ends of the guide block 5, and the two coal-leveling screws 401 are respectively fixedly connected to the sprockets 402, and a chain 403 is set between the sprockets 402, so that only a single coal-leveling motor 4 is required to drive the two coal-leveling screws 401 to rotate synchronously in the same direction, and then drive the guide block 5 to reciprocate from both ends of the guide block 5. By increasing the driving point, while improving the stability of the guide block 5 during movement, there is no need to set a plurality of driving sources, so that the production cost is also controlled.

[0038] Furthermore, by fixing a scraper 501 on the bottom surface of the guide block 5, whose lowest point is at least lower than the bottom surface of the guide beam 2, the scraper 501 can push the coal to a position lower than the top surface of the bucket after the guide beam 2 contacts the bucket of the coal transport vehicle. By increasing the distance between the top surface of the coal and the top surface of the bucket, the coal is less likely to scatter from the bucket during transportation.

[0039] Specifically, the scraper 501 is hollowed out, so that the mass of the scraper 501 is reduced without changing the flattening area of ​​the scraper 501, so that the friction resistance of the guide block 5 during reciprocating motion is lower, and the guide block 5 runs more smoothly.

[0040] Embodiment 2

[0041] Based on the first embodiment, specifically, Figure 1-4 As shown, a lifting motor 3 is connected to the rear side of the top surface of the suspension 1, and two lifting cavities are symmetrically opened in the rear column of the suspension 1. A connecting block 202 which can only slide along the opening direction of the lifting cavity and is fixedly connected to the rear door of the guide beam 2 is symmetrically arranged in the lifting cavity. A first lifting screw 301 and a second lifting screw 302 which are rotatably connected to the two connecting blocks 202 are arranged in the lifting cavity. The same rotating shaft 303 is arranged on the top surface of the first lifting screw 301 and the second lifting screw 302, and the output shaft of the lifting motor 3 is fixedly connected to the rotating shaft 303 on the top surface of the first lifting screw 301. A transmission belt 304 is set between the rotating shafts 303, so that starting the lifting motor 3 can drive the first lifting screw 301 and the second lifting screw 302 to rotate synchronously in the same direction, thereby driving the two connecting blocks 202 to slide along the opening direction of the lifting cavity, so as to adjust the height of the guide beam 2.

[0042] By arranging limit blocks 203 on both sides of the guide beam 2 near the front, and opening a sliding groove adapted to the limit blocks 203 in the column on the front of the suspension 1, when the guide beam 2 is raised or lowered, the force points can be dispersed to the connection between the connecting block 202 and the limit blocks 203 and the guide beam 2, thereby dispersing the force borne by the connection between the connecting block 202 and the guide beam 2 during the lifting process, making the guide beam 2 more stable during the lifting process, and also providing a certain protection for the connection between the connecting block 202 and the guide beam 2.

[0043] By fixing the mounting frame 102 on the rear side of the top surface of the suspension 1, the lifting motor 3 is installed on the inner top surface of the guide beam 2, ventilation holes are opened on the left and right sides of the mounting frame 102, and dustproof nets are set in the ventilation holes, so that the mounting frame 102 can protect the main body of the lifting motor 3 during the use of the device, and the ventilation holes opened thereon can improve the air circulation in the mounting frame 102 without hindering the protection of the lifting motor 3, thereby assisting the lifting motor 3 in dissipating heat, and the dustproof net set in the ventilation holes can prevent foreign matter from entering the mounting frame 102 without affecting the heat dissipation of the lifting motor 3, so that the interior of the mounting frame 102 is more tidy.

[0044] In addition, reference Figure 1By arranging side beams 101 on the top surface and side surfaces of the suspension 1, the connection relationship between the four columns of the suspension 1 is fixed, thereby improving the strength of the suspension 1, and thus making the lifting and lowering of the guide beam 2 more stable, and by arranging a reinforcing plate 204 at the center of the top surface of the guide beam 2, the two guide beams 2 are fixedly connected, thereby improving the strength of the guide beam 2.

[0045] Working principle:

[0046] When in use, first set the suspension 1 below the coal outlet, and then park the coal transport vehicle between the four columns of the suspension 1, and then start to discharge coal. When the coal accumulation extends out from the bucket of the coal transport vehicle, start the coal leveling motor 4 to drive the coal leveling screw 401 to rotate and drive the guide block 5 to reciprocate, so that the scraper 501 contacts the upper end of the coal accumulation and pushes the coal on it to the empty space in the bucket, thereby realizing the coal leveling operation of the transport vehicle.

[0047] If the height of the transport bucket of the coal transport vehicle is not in the same plane as the guide block 5, the lifting motor 3 can be started to drive the first lifting screw 301 and the second lifting screw 302 to rotate, so that the connecting block 202 descends, and then drives the guide beam 2 to descend until the scraper 501 reaches the transport bucket, and the adjustment operation is completed.

[0048] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
