[0021] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with the embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the present invention, and does not strictly limit the scope of protection specifically requested by the present invention.

[0022] like Figure 1 As shown, a gravel laying device for branch line railway construction comprises two rail units 1, and a gravel laying vehicle 2 is mounted on the two rail units 1. When the gravel laying vehicle 2 moves, gravel can be thrown between the two rail units 1 and on the sides of the two rail units 1, so that the gravel is laid between the two rail units 1 and on the sides of the two rail units 1;

[0023] At the same time, a stone pushing plate 3 is fixedly connected to the rear side of the gravel paving vehicle 2, and two gap grooves 4 are provided on the stone pushing plate 3. The two rail units 1 are respectively located inside the two gap grooves 4. At this time, when the gravel paving vehicle 2 drives the stone pushing plate 3 to move, the stone between the two rail units 1 and the sides of the two rail units 1 will be flattened by the stone pushing plate 3 to complete the paving of the stones. However, at the same time, since rail side grooves 14 are provided on both sides of the rail unit 1, some stones will remain inside the rail side grooves 14. In order to be able to clean the stones remaining inside the rail side grooves 14 more conveniently, a cleaning unit 5 that can be moved to the inside of the rail side grooves 14 is installed on the rear side of the stone pushing plate 3. When the gravel paving vehicle 2 drives the stone pushing plate 3 to move, the stones remaining inside the rail side grooves 14 will be cleaned by the cleaning unit 5.

[0024] like Figure 1-2As shown, the cleaning unit 5 includes a bracket plate 20 connected to the stone pushing plate 3, and a transmission motor 21 is fixedly connected to the bracket plate 20. The output end of the transmission motor 21 is fixedly connected to a vertically arranged rotating shaft 22, and a plurality of push plates 24 in a circular array are mounted on the circumference of the rotating shaft 22. At this time, when the transmission motor 21 is started, it will drive the rotating shaft 22 to rotate. When the rotating shaft 22 rotates, the plurality of push plates 24 will be rotated in turn into the interior of the rail side groove 14 to flatten the stones inside the rail side groove 14, thereby effectively cleaning the residual stones inside the rail side groove 14.

[0025] At the same time, if Figure 2 As shown, in order to reduce the jamming phenomenon of the push plate 24 inside the rail side groove 14, the push plate 24 and the rotating shaft 22 are connected by an elastic connecting member 23, and the elastic connecting member 23 can be a spring steel sheet. When the side edge of the push plate 24 and the stones inside the rail side groove 14 are against each other, the elastic connecting member 23 is deformed so that the rotating shaft 22 can still drive the push plate 24 to rotate, thereby reducing the jamming phenomenon of the push plate 24 inside the rail side groove 14.

[0026] Among them, Figure 1-3 As shown, the rail unit 1 includes a lower rail 13, a plurality of locking screws 7 are installed on both sides of the lower rail 13, the lower rail 13 is fixed to the foundation by the locking screws 7, a middle rail 12 is fixedly connected to the middle position of the upper side of the lower rail 13, and a top rail 11 is fixedly connected to the upper side of the middle rail 12;

[0027] In order to make it easier to install the gap groove 4 on the outside of the rail unit 1, the technical solution improves the structure of the gap groove 4, specifically, the gap groove 4 includes a middle groove 8 opened on the stone pushing plate 3, the width of the middle groove 8 is greater than the width of the top rail 11, a bottom groove 9 is opened on the stone pushing plate 3 and located at the lower side of the middle groove 8, the width of the bottom groove 9 is greater than the width of the lower rail 13, and screw grooves 10 are opened on the stone pushing plate 3 and located on both sides of the gap groove 4, which are located on the upper side of the bottom groove 9, and the width of the screw groove 10 is greater than the width of the upper part of the locking screw 7. At this time, through the structural setting of the gap groove 4, the gap groove 4 can be clamped on the outside of the rail unit 1 by moving the stone pushing plate 3 downward, and when the stone pushing plate 3 moves horizontally, it can push stones in a larger range.

[0028] At the same time, in order to maximize the cleaning of stones inside the rail side groove 14, a guide ring 25 is fixedly connected to the lower end of the rotating shaft 22. The radius of the guide ring 25 is greater than the distance between the locking screw 7 and the middle rail 12. At this time, when the guide ring 25 and the locking screw 7 meet, the locking screw 7 will apply kinetic energy to the cleaning unit 5 to move away from the middle rail 12 through the arc setting of the guide ring 25. The rear side of the stone pushing plate 3 is fixedly connected to the elastic bracket group 6 that is compatible with the guide ring 25. The bracket plate 20 is fixedly connected to the elastic bracket group 6, by the setting of the elastic bracket group 6, the cleaning unit 5 can move horizontally under the action of the guide ring 25. At this time, when the rail unit 1 is not provided with a locking screw 7 in an area, the push plate 24 can be directly moved to the inside of the rail side groove 14 for cleaning, thereby maximizing the cleaning of stones in the rail side groove 14. When the rail unit 1 is provided with a locking screw 7 in an area, the push plate 24 will move out from the inside of the rail side groove 14 under the action of the guide ring 25, thereby reducing the influence of the locking screw 7 on the push plate 24.

[0029] Among them, Figure 1-2 and Figure 4 As shown, the elastic bracket group 6 includes a guide member 15 fixedly connected to the stone pushing plate 3, and a slide plate 16 is slidably connected inside the guide member 15. The slide plate 16 and the bracket plate 20 are fixedly connected. When the slide plate 16 slides horizontally inside the guide member 15, it can drive the bracket plate 20 to move together. A first side plate 17 is fixedly connected to the guide member 15, and a second side plate 18 is fixedly connected to the end of the slide plate 16 away from the rail unit 1. A return spring 19 is installed between the first side plate 17 and the second side plate 18. Under the elastic action of the return spring 19, the bracket plate 20 will be pushed toward the direction close to the rail unit 1.

[0030] The working principle of the utility model is as follows: when the stone paving vehicle 2 drives the stone pushing plate 3 to move, the stone between the two rail units 1 and the sides of the two rail units 1 are flattened by the stone pushing plate 3 to complete the laying of the stone;

[0031] At the same time, when the stone push plate 3 moves, the stones remaining inside the groove 14 on the side of the rail will be cleaned through the cleaning unit 5;

[0032] In summary, the present technical solution can continuously perform two leveling processes on the laid stones through the stone pushing plate 3 and the cleaning unit 5. The first leveling process is to level the stones between the two rail units 1 and on the sides of the two rail units 1, and the second leveling process is to clean the stones remaining inside the groove 14 on the side of the rail, so that the laid stones can be leveled to a greater extent.

[0033] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
