[0038] The embodiment of the present application discloses a shape-holding bin structure of a mobile pallet of a coal and gangue sorting device.

[0039] Example 1

[0040] Reference Figure 1 , 2 4. A shape holding bin structure of a mobile support plate of a coal and gangue sorting device, comprising a bin body 1 for holding the bin and a receiving plate 3 for receiving materials, and a flat elliptical tube 2 for reciprocating movement is slidably arranged in the middle of the inner cavity of the bin body 1, and both sides of the flat elliptical tube 2 are movable through the middle of a limiting ring 13, and one of the two limiting rings 13 is fixedly connected to the middle of a first support plate 11, and the other of the limiting rings 13 is fixedly connected to the middle of a second support plate 12, and the first support plate 11 and the second support plate 12 are symmetrically arranged, and the first support plate 11 and the second support plate 12 not only have the same structure, but also have the same installation method.

[0041] Through the above-mentioned arrangement, the flat oval tube 2 passes through the limiting ring 13, which can make the flat oval tube 2 move back and forth more smoothly in the middle of the first support plate 11 and the second support plate 12, avoiding unnecessary loss caused by friction between the flat oval tube 2 and the first support plate 11 and the second support plate 12, thereby increasing the cost. On the contrary, the limiting ring 13 not only plays a better sliding role for the flat oval tube 2, but also can support and guide the flat oval tube 2. The first support plate 11 and the second support plate 12 have the same structure and the same installation method, which can simplify the installation and make the installation convenient and quick. The symmetrical arrangement of the first support plate 11 and the second support plate 12 can make the two limiting rings 13 and the flat oval tube 2 located on the same straight line, avoiding the flat oval tube 2 from shaking during reciprocating operation, thereby causing deformation of the flat oval tube 2, thereby increasing the use cost.

[0042] Reference Figure 3 , 4 , a group of longitudinal guide wheels 6 are slidably arranged on the upper surface of the flat oval tube 2, and a group of longitudinal guide wheels 6 are also slidably arranged on the lower surface of the flat oval tube 2, and each group of longitudinal guide wheels 6 is set as the number of longitudinal guide wheels 6 required, and the two groups of longitudinal guide wheels 6 at the upper and lower parts of the flat oval tube 2 are symmetrically arranged, and the cross bar inside the longitudinal guide wheel 6 is slidably connected to the inner wall of one side of the second cover plate 8, and the cross bar inside the longitudinal guide wheel 6 is slidably connected to the inner surface of the first cover plate 7 away from the second cover plate 8, and the second cover plate 8 and the first cover plate 7 are symmetrically arranged on both sides of the longitudinal guide wheel 6, and the first cover plate 7 and the second cover plate 8 have not only the same structure, but also the same installation method;

[0043] The lower inner surface of the second cover plate 8 and the first cover plate 7 is fixedly connected to the outer surface of one side of the bottom plate 10 by screws, and is fixedly connected to the cover plate fixing block 14 on the middle upper surface of the bottom plate 10, and one side surface of the cover plate fixing block 14 is fitted with the lower inner surface of the first cover plate 7 and the second cover plate 8, and the cover plate fixing block 14 is fixedly connected to the second cover plate 8 and the first cover plate 7 by screws, and the upper side of the second cover plate 8 and the first cover plate 7 away from the bottom plate 10 is fixedly connected to the side surface of the top plate 9 by screws, and an opening for the anti-pressure guide wheel to work is opened on the side of the top plate 9 away from the first support plate 11, and the top plate 9 and the bottom plate 10 are not only symmetrically arranged, but the middle lower surface of the top plate 9 is also fixedly connected to the upper surface of the cover plate fixing block 14.

[0044] Through the above-mentioned arrangement, the two groups of longitudinal guide wheels 6 arranged on the upper and lower surfaces of the flat elliptical tube 2 can not only guide the flat elliptical tube 2, but also provide longitudinal support force to the flat elliptical tube 2, reduce the possibility of longitudinal force deformation of the flat elliptical tube 2, and improve the service life of the flat elliptical tube 2. The two groups of longitudinal guide wheels 6 are symmetrically arranged so that the two groups of longitudinal guide wheels 6 are on the same straight line, which can make the force on each longitudinal guide wheel 6 more uniform. The longitudinal guide wheels 6 should be set according to the corresponding number of longitudinal guide wheels 6 according to the force evenly distributed on the upper and lower surfaces of the flat elliptical tube 2.

[0045] The second cover plate 8 is connected to the first cover plate 7 with the top plate 9 and the bottom plate 10 by screws, which facilitates disassembly and assembly. The first cover plate 7 and the second cover plate 8 are installed in the same way, and the top plate 9 and the bottom plate 10 are installed in the same way, which makes the installation more convenient and can be disassembled according to the damage of components in different positions according to my structure.

[0046] Reference Figure 3 , 4 , 5. Longitudinal shock absorbing mechanisms 5 are provided at both ends of the cross bar inside the longitudinal guide wheel 6, and the longitudinal shock absorbing mechanism 5 includes a second fixing plate 51 fixed to the one side surface of the first cover plate 7 by screws, and a longitudinal moving slot 57 for the movement of the cross bar inside the longitudinal guide wheel 6 is opened in the middle of the second fixing plate 51, and the upper surface of the inner cavity of the longitudinal moving slot 57 is fixedly connected to the upper end of the spring 55, and the lower part of the spring 55 abuts against the upper surface of the pressure plate 56, and the one side surface of the pressure plate 56 is fixedly connected to the one side surface of the lower part of the side baffle 52, and the side baffle 52 is located on the one side surface of the pressure plate 56 and is fixed with two sliding grooves 53, and the two sliding grooves 53 are symmetrically arranged, and the inner cavity surface of the sliding groove 53 is slidably connected to the outer surface of the sliding rod 54, and the one side surface of the sliding rod 54 is fixedly connected to the one side opening surface of the longitudinal moving slot 57.

[0047] Through the above arrangement, the longitudinal shock absorbing mechanism can squeeze the pressure plate 56 through the internal cross bar when the longitudinal guide wheel 6 is subjected to force, and transmit the force to the spring 55 through the pressure plate 56. The spring 55 is deformed by the force and shrinks, so that the cross bar inside the longitudinal guide wheel 6 can move in the longitudinal moving slot 57, unloading a part of the force, and then the longitudinal guide wheel 6 is pushed back to its original position by the rebound force of the spring 55. The side baffle 52 is fixedly connected to the pressure plate 56, and the slide groove 53 and the slide rod 54 slide with each other, which can prevent the deformed spring 55 from being separated from the longitudinal moving slot 57 and does not affect the movement of the pressure plate 56 and the longitudinal guide wheel 6.

[0049] Through the above-mentioned arrangement, the side guide mechanism 4 is arranged at the same position as the first cover plate 7 and the second cover plate 8, so that the plurality of side guide mechanisms 4 are all located on the same horizontal line and are evenly distributed on both sides of the flat oval tube 2, which can exert lateral force on the flat oval tube 2, so that the flat oval tube 2 can maintain a stable operation without lateral swing, causing deformation of the flat oval tube 2, thereby reducing the service life of the flat oval tube 2, and the rubber-coated side guide wheel 42 not only reduces the friction on the surface of the flat oval tube 2, but also has a good supporting effect on the flat oval tube 2.

[0050] The implementation principle of the shape holding bin structure of the mobile pallet of the coal and gangue sorting device in the embodiment of the present application is as follows: when the flat oval tube 2 reciprocates back and forth inside the device, the limit rings 13 of the device at both ends of the flat oval tube 2 will support and limit the head and tail of the flat oval tube 2, so that the flat oval tube 2 can remain horizontal during operation, and the longitudinal guide wheels 6 located at the upper and lower parts of the flat oval tube 2 inside the device will rotate automatically following the movement of the flat oval tube 2, providing support for the flat oval tube 2 while reducing friction through self-rotation, and the side guide mechanism 4 can provide support for the side of the flat oval tube 2, and the rubber-coated side guide wheels 42 in the side guide mechanism 4 can also rotate following the movement of the flat oval tube 2.
