[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. The present invention proposes a crushed stone paving and leveling device and method for railway construction. When it is necessary to control the switch of the stop cover and open the stop cover, the first gear rotates, and the first gear drives the first annular chute block and the belt to rotate synchronously. Under the action of the belt, the second annular chute ring rotates along the third round rod as a driven shaft. Due to the existence of the stop ring and the first stop plate, the second annular chute ring will not deviate from the track. At this time, under the action of the third gear, the first toothed long block drives the first I-shaped block to move along the third U-shaped block until the first I-shaped block is separated from the second U-shaped block. At the same time, under the action of the fifth gear, the second toothed long block synchronously drives the second I-shaped block to move along the fourth U-shaped block until the second I-shaped block is separated from the first U-shaped block. As one end of the placement box is lifted, under the action of the first round rod, the notch can be opened, and the gravel can pass through the notch and enter the railway gravel paving section via the discharge chute. When it is necessary to close the stop cover, the lifted end of the placement box is laid flat, and the first gear is rotated in the opposite direction until the second I-shaped block enters the first U-shaped block and engages with each other, and the first I-shaped block enters the second U-shaped block and engages with each other. At this time, the stop cover can be closed.

[0023] 2. The present invention proposes a gravel paving and leveling device and method for railway construction. When the placement box needs to be lifted, the motor is started to drive the cylinder to rotate, and the cylinder drives the rotating shaft to rotate, so that the iron chain is coiled on the outer surface of the rotating shaft. As the iron chain shortens, under the action of the fourth round rod and the second round groove, the iron chain end of the placement box will be lifted up. At this time, the second ring gear will rotate synchronously with the rotation of the rotating shaft. At this time, the second ring gear will drive the sixth gear to rotate, and because the sixth gear and the first gear are in the shape of a right-angle gear, the sixth gear is movably connected to the first gear. At this time, the first gear will rotate along with the rotation of the sixth gear, thereby controlling the switch of the gear cover through the first gear.

[0024] 3. The present invention proposes a crushed stone paving and leveling device and method for railway construction. When the cylinder needs to be fixed after it rotates, the connecting wire is coiled on the outer surface of the fixing column, and then the ring is set on the outer surface of the fixing column, and the connecting wire is in a taut state. Then the threaded rod is placed inside the threaded groove, and the disc is rotated so that the threaded rod and the threaded groove are fixed to each other. Under the action of the disc, the ring cannot be separated from the outer surface of the fixing column, and the fixing column can be prevented from continuing to rotate, that is, the cylinder can be prevented from continuing to rotate. Then the chain can be coiled on the outer surface of the fixing column, and the placement block is placed inside the placement groove, and the magnetism of the first electromagnetic plate and the second electromagnetic plate is changed so that they are oppositely attracted to each other. At this time, the placement block and the placement groove can be engaged and fixed with each other, and the chain can be in a taut state, which can further prevent the fixing column from rotating again, that is, prevent the cylinder from continuing to rotate. Under the dual action of the connecting wire and the chain, the cylinder can be braked, and the accidental rotation of the rod can be prevented from causing accidental scattering of crushed stone.

[0042] When it is necessary to control the switch of the gear cover 53, when it is necessary to open the gear cover 53, the first gear 55 rotates, and the first gear 55 drives the first annular slide block 541 and the belt 56 to rotate synchronously.

When it is necessary to close the stop cover 53, the lifted end of the placement box 51 is laid flat, and the first gear 55 is rotated in the opposite direction until the second I-shaped block 536 enters the first U-shaped block 511 and engages with each other, and the first I-shaped block 535 enters the second U-shaped block 512 and engages with each other. At this time, the stop cover 53 can be closed.

[0043] In order to solve the technical problem of controlling the lifting of the placement box 51 and the synchronous opening and closing of the stop cover 53, please refer to Figure 2 , Figure 4 and Figure 8 , providing the following technical solutions:

[0044] The rotating mechanism 6 includes an iron chain 61 arranged at the upper end of the placement box 51, an L-shaped block 62 arranged at the upper end of the main box body 1, and a vertical block 63 arranged at the upper end of the main box body 1. A rotating shaft 64 is arranged above the main box body 1, one end of the rotating shaft 64 is movably connected to the L-shaped block 62, and the other end of the rotating shaft 64 is movably penetrated inside the vertical block 63, and a stopper 641 is arranged on the outer surface of the rotating shaft 64. A rotating shaft 64 is arranged above the main box body 1, one end of the rotating shaft 64 is movably connected to the L-shaped block 62, and the other end of the rotating shaft 64 is movably penetrated inside the vertical block 63, and a stopper 641 is arranged on the outer surface of the rotating shaft 64. A second ring gear 642 is also provided on the surface, one end of the iron chain 61 is fixedly arranged between the stop block 641 and the second ring gear 642, a cylinder 643 is provided at one end of the rotating shaft 64, and the cylinder 643 is externally connected to the motor, and a sixth gear 65 is movably provided at one end of the L-shaped block 62, and the sixth gear 65 is movably connected to the second ring gear 642, and the sixth gear 65 and the first gear 55 are in the shape of a right-angle gear, and the sixth gear 65 is movably connected to the first gear 55, and fourth round rods 66 are provided on both sides of the placement box 51, and a second circular groove 67 is opened on the inner wall of the main box body 1, and the fourth round rod 66 is movably arranged inside the second circular groove 67.

[0045] When it is necessary to lift the placement box 51, the motor starts to drive the cylinder 643 to rotate, and the cylinder 643 drives the rotating shaft 64 to rotate, so that the iron chain 61 is coiled on the outer surface of the rotating shaft 64. As the iron chain 61 shortens, under the action of the fourth round rod 66 and the second round groove 67, the end of the iron chain 61 of the placement box 51 will be lifted up. At this time, as the rotating shaft 64 rotates, the second ring gear 642 will rotate synchronously. At this time, the second ring gear 642 will drive the sixth gear 65 to rotate, and because the sixth gear 65 and the first gear 55 are in the shape of a right-angle gear, the sixth gear 65 is movably connected to the first gear 55. At this time, the first gear 55 will rotate along with the rotation of the sixth gear 65, thereby controlling the switch of the gear cover 53 through the first gear 55.

[0046] In order to solve the technical problem of preventing the cylinder 643 from continuing to rotate, please refer to Figure 8 , Fig.12 and Fig.13 , providing the following technical solutions:

[0047] The control mechanism 7 includes a fixed column 71 opened on the outer surface of the cylinder 643, a threaded rod 72 arranged on one side of the fixed column 71 and a disc 73 arranged at one end of the threaded rod 72, a threaded groove 711 is opened at one end of the fixed column 71, and the threaded rod 72 corresponds to the threaded groove 711, a ring 74 is movably arranged on the outer surface of the fixed column 71, a connecting line 75 is arranged on the outer surface of the ring 74, and one end of the connecting line 75 is fixedly arranged on the upper end of the main box body 1, a chain 76 is arranged on one side of the vertical block 63, a placement block 761 is arranged at one end of the chain 76, and a first electromagnetic plate 7611 is arranged at one end of the placement block 761, a placement groove 77 is opened on one side of the vertical block 63, a second electromagnetic plate 771 is arranged on the inner wall of the placement groove 77, the placement groove 77 corresponds to the placement block 761, and the first electromagnetic plate 7611 corresponds to the second electromagnetic plate 771.

[0048] When the cylinder 643 needs to be fixed after it rotates, the connecting wire 75 is coiled around the outer surface of the fixing column 71, and then the ring 74 is sleeved on the outer surface of the fixing column 71, and the connecting wire 75 is in a taut state, and then the threaded rod 72 is placed inside the thread groove 711, and the disk 73 is rotated to fix the threaded rod 72 and the thread groove 711 to each other. Under the action of the disk 73, the ring 74 cannot be separated from the outer surface of the fixing column 71, and the fixing column 71 can be prevented from continuing to rotate, that is, the cylinder 643 can be prevented from continuing to rotate. Then the chain 76 can be coiled around the fixing column 71. On the outer surface of the fixed column 71, the placement block 761 is placed inside the placement groove 77, and the magnetism of the first electromagnetic plate 7611 and the second electromagnetic plate 771 is changed so that they attract each other with opposite polarities. At this time, the placement block 761 and the placement groove 77 can be engaged and fixed with each other, and the chain 76 is in a taut state, which can further prevent the fixed column 71 from rotating again, that is, prevent the cylinder 643 from continuing to rotate. Under the dual action of the connecting line 75 and the chain 76, the cylinder 643 can be braked, which can prevent the accidental rotation of the cylinder 643 from causing the accidental scattering of gravel.

[0049] Another technical solution proposed by the present invention is to provide an implementation method of a crushed stone paving and leveling device for railway construction, comprising the following steps:

[0050] Step 1: The iron chain 61 can be coiled around the outer surface of the rotating shaft 64 by rotating the cylinder 643 to lift one end of the placing box 51. At this time, the gravel is accumulated at the other end of the placing box 51, that is, at the notch 52;

[0051] Step 2: The second annular chute ring 57 is driven to rotate by the rotation of the belt 56, so that the first toothed long block 5351 and the second toothed long block 5361 move accordingly, so that the first I-shaped block 535 is separated from the second U-shaped block 512, and the second I-shaped block 536 is separated from the first U-shaped block 511;

[0052] Step 3: As one end of the placement box 51 is lifted, the stop cover 53 rotates accordingly, so that the slot 52 is opened, so that the crushed stone can pass through the slot 52 and enter the railway through the discharge chute 2;

[0053] Step 4: With the movement of the main box 1, the gravel passes through the gravel turning and laying device 3 and the gravel leveling device 4 in sequence. The gravel turning and laying device 3 lays the gravel evenly on the railway, and the gravel leveling device 4 rolls the gravel. At this point, all implementation steps are completed.

[0054] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0055] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
