In order to prevent the control of the tippler from being separated from the opposite side of the tippler when the vehicle is tipped over 180 degrees, the overturning angle of the tippler is normally 165 degrees and maximally 175 degrees. In order to adapt to vehicle types with different widths and heights, the pressure head of the tippler is generally longer than the top side beam of the open wagon, so materials at the maximum dumping corner still cannot be dumped completely due to the length of the pressure head and the like, and certain materials are always stored. For years, in the field of car dumper, various coping schemes are developed, and the materials can not be completely unloaded.

According to the problem of aggregate at the pressure head caused by insufficient overturning angle of the conventional tippler, the tippler without material accumulation and the operation method are provided. The turnover angle of the tippler is larger than 180 degrees and larger than the repose angle of the material. The technical means adopted by the invention are as follows:
a tippler without material accumulation comprises a tippler carrier roller and a tippler rotor, wherein the tippler rotor can turn over and unload materials on the tippler carrier roller, the tippler rotor is internally connected with a tippler beam, a tippler counter beam, a tippler backup plate and a tippler platform, the tippler beam and the tippler counter beam are used for pressing and holding an upper side beam of an open wagon from top to bottom, the tippler backup plate is positioned on the tippler rotor and on the tippler side and used for supporting the side surface of the open wagon from the tippler side, and the tippler platform can support the open wagon through open wagon wheels; the side-to-side supporting device is connected to a rotor of the tippler and used for supporting the side face of the side-to-side of the open wagon from the side-to-side of the.
Furthermore, in the dumping process, the dumping angle B is not smaller than the repose angle a of the materials, and after dumping is finished, the overturning angle is larger than 180 degrees, and no residual materials exist.
An operation method of a tippler without material accumulation comprises the following steps:
3, moving the dumping side backup plate from the dumping side to the open wagon, and abutting against the dumping side surface of the open wagon; the overturning opposite side supporting device moves from the overturning opposite side to the open wagon and leans against the overturning opposite side of the open wagon;

All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 and 2 show the mechanism composition of a conventional tippler, which specifically comprises a tippler carrier roller and a tippler rotor, wherein a tipping side pressing beam 1 and a tipping pair side pressing beam 2 are positioned on the tippler rotor 4, and the two beams are used for pressing and holding an upper side beam of an open wagon 8 from top to bottom; the tipping side backup plate 3 is positioned on the tipping side of the tipper rotor 4 and is used for supporting the side surface of the open wagon from the tipping side; the tipper rotor 4 is positioned on the tipper carrier roller 7 and can rotate on the tipper carrier roller 7; the tippler platform 5 is a part of the tippler rotor 4 and supports the open wagon 8 through wheels 9; the tipping-side platform guard rail 6 is connected to the tippler platform 5 and is used for blocking the side surface of the wheel 9 of the open wagon 8 at the tipping-side in the tipping process and preventing the wheel 9 from being separated from the track on the tippler platform 5 from the side surface due to gravity in the tipping process; the tippler carrier roller 7 is a supporting device of the tippler rotor 4, and the tippler rotor 4 can overturn and unload materials on the supporting device.
The working principle of the existing car dumper is shown in the attached drawings 1 and 3:
after the materials 10 are conveyed by the open wagon 8 into the rotor 4 of the tippler, the open wagon stops on the platform 5 of the tippler, the dumping side pressing beam 1 and the dumping pair side pressing beam 2 are pressed on the tippler from the upper part, and the fixation in two directions in the vertical direction is realized through the platform 5; after the pressing is finished, the dumping side backup plate 3 moves from the dumping side to the vehicle and is abutted against the dumping side of the open wagon; after the 3 directions of the vehicle are fixed, the tippler rotor 4 rotates towards the tipping side and drives each part on the tippler rotor and the vehicle to rotate, when the tipping angle is larger than the angle a of repose of the materials 10 in the open wagon, the materials begin to be unloaded from the open wagon until the tippler rotor 4 turns to the maximum tipping angle A.
As shown in fig. 4, during the dumping process from 90 ° to the maximum dumping angle a, the wheels 9 of the vehicle 8 have a tendency to slide down, being stopped by the side platform guard rail on the dumping platform 5 of the dumper.
In order to prevent the vehicle from falling out of the side opposite the empty dump, the maximum dump angle a is generally not greater than 180 °.
As shown in fig. 5, due to the angle of repose a, there will be residual material 10 between the roll-over side bolster 1 and the open wagon 8.
It can be seen that: along with the increase of the turning angle, the residual materials are correspondingly reduced until the turning angle is larger than 180 degrees plus the material repose angle, and no residual materials exist.

As shown in the attached figures 6-7, the working principle of the no-material-accumulation car dumper is as follows:
after the open wagon 8 transports the materials 10 into the tipper rotor 4, the open wagon stops on the tipper platform 5, the tipper beam 1 and the tipper beam 2 press the tipper from above, and the platform 5 is used for realizing the fixation in two directions of the vertical direction; after the pressing is finished, the dumping side backup plate 3 moves from the dumping side to the open wagon 8 and abuts against the dumping side of the open wagon 8; meanwhile, the dumping opposite side supporting device 11 moves to the side face of the dumping opposite side vehicle, after the fixing of the vehicles in 4 directions of up-down and left-right is completed, the tipper rotor 4 rotates to the dumping side and drives each part on the tipper rotor, the vehicle 8 and the materials 10 to rotate, when the dumping angle is larger than the repose angle a of the materials 10 in the open wagon 8, the materials 10 start to be dumped from the open wagon 8, and before the tipper rotor 4 is turned to 180 degrees, the working process is the same as that of the conventional tipper shown in the attached figures 1 and 3; as shown in fig. 8 and 9, after the turning angle exceeds 180 °, the vehicle 8 is supported by the newly added supporting device 11 so as not to fall out from the turning-unloading side, the wheels 9 of the open wagon 8 are blocked by the newly added turning-unloading side platform guard rail 12 until the turning angle is 180 ° + the turning-unloading angle B, and turning-unloading is stopped, the larger the turning-unloading angle B is, the less accumulated material is, and if the turning-unloading angle B is not smaller than the repose angle a of the material, all the material existing between the pressing beam 1 and the vehicle 8 is unloaded without accumulated material.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
