[0023] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0024] like Figures 1 to 3 As shown, the embodiment of the utility model provides a paving device for highway gravel cushion construction, comprising:

[0025] The material storage box 1 has a material inlet 16 and a material outlet 17 for feeding and discharging materials;

[0026] A feeding cylinder 11 is rotatably arranged at a discharge port 17 and is provided with a plurality of feeding troughs 12 for conveying sand and gravel;

[0027] The driver 8 is arranged at one side of the storage box 1 and is transmission-connected to the feed cylinder 11 , and is used to drive the feed cylinder 11 to rotate in the discharge port 17 , so that each feed slot 12 corresponds to the mouth of the discharge port 17 in turn, and delivers the gravel it carries out of the discharge port 17 .

[0028] In the embodiment of the present invention, the top of the material storage box 1 is a feeding port 16 for feeding, and the bottom is a discharging port 17 for discharging, and the feeding cylinder 11 closes the discharging port 17. When the gravel is put into the material storage box 1, it is intercepted by the feeding cylinder 11 and all stays in the material storage box 1. When the driver 8 drives the feeding cylinder 11 to rotate, the gravel in the material storage box 1 enters each feeding trough 12 of the feeding cylinder 11 one by one, and when the feeding cylinder 11 rotates, each feeding trough 12 circulates through the discharging port 17, and the gravel it carries is sent out of the discharging port 17 to be spread on the corresponding road surface area to achieve paving. Under the premise that the material storage box 1 moves forward, the gravel cushion layer can be spread on a large area of ​​road surface under the continuous rotation of the feeding cylinder 11. There is no need for manual operation using tools, which saves time and manpower. The feeding trough 12 continuously feeds material to the discharging port 17, and the amount of gravel sent out is more uniform and the thickness is more uniform. The driver 8 is a driving motor, and is connected to the feeding barrel 11 through a belt and a pulley.

[0029] Based on the above scheme, if Figure 3 As shown, a filter plate 14 is provided in the material storage box 1 for filtering the gravel passing through the material storage box 1. Under the action of the filter plate 14, after the gravel is put into the material storage box 1, it is intercepted by the filter plate 14. The gravel smaller than the aperture of the filter plate 14 can pass through the filter plate 14 and enter the discharge port 17, while the gravel larger than the aperture of the filter plate 14 stays above the filter plate 14, ensuring that the gravel particles used for paving are finer, thereby ensuring the quality of subsequent construction.

[0030] Specifically, the filter plate 14 is arranged in an inclined state on the storage box 1 and has a highest point and a lowest point. A through groove 15 corresponding to the lowest point is opened on the side of the storage box 1, and one side of the through groove 15 has a collecting box 3 connected to the storage box 1. The filter plate 14 is in an inclined state in the storage box 1. The gravel smaller than the aperture of the filter plate 14 is not affected by the inclination, but the gravel larger than the aperture of the filter plate 14 will be affected by the inclination and move from the highest point of the filter plate 14 to the lowest point, and enter the collecting box 3 through the through groove 15 for collection, so as to be processed and used again later. In addition, the permeability of the filter plate 14 is guaranteed, and the normal filtering effect is continuously guaranteed.

[0031] Moreover, a discharge box 9 is provided at the bottom of the collecting box 3, and the opening of the discharge box 9 is hinged with a baffle 10 for opening or closing the opening of the discharge box 9. The baffle 10 and the discharge box 9 can be connected in a fixed manner using a traditional lock. When the collecting box 3 collects a certain amount of larger gravel, the gravel collected in the collecting box 3 can be taken out by opening the baffle 10.

[0032] Specifically, a guide plate 13 is provided on the inner side of the storage box 1, and the end of the guide plate 13 extends to the side of the feeding barrel 11. The guide plate 13 is inclined on the inner side of the storage box 1. Since the diameter of the feeding barrel 11 is smaller than the width of the storage box 1, the guide plate 13 can guide all the screened gravel to the feeding barrel 11 to facilitate delivery to the discharge port 17.

[0033] Specifically, Figure 1 As shown, the storage box 1 is provided with a viewing panel 2, through which the conveying status of the gravel in the storage box 1 can be clearly seen.

[0034] Based on the above scheme, if Figure 2 As shown, the mobile frame 6 is also included. The bottom end of the storage box 1 is provided with a support frame 7, which is sleeved on the mobile frame 6 and is rotatably provided with a screw rod 5, which is threadedly connected to the mobile frame 6. When in use, the screw rod 5 can be rotated to make the screw rod 5 rise or fall on the mobile frame 6, thereby driving the support frame 7 connected to the screw rod 5 to move up and down, thereby adjusting the height of the storage box 1, and the device can be better paved when facing an uneven road surface, and the support frame 7 is sleeved on the mobile frame 6, and the support frame 7 can be limited by the mobile frame 6 to ensure the stability of the adjustment. The mobile frame 6 is composed of a frame body and a pulley, so that the frame body can rely on the pulley to drive the entire device to move, which is convenient for mobile operation. In order to facilitate operation, the screw rod 5 is fixed with a knob 4, and when the screw rod 5 is adjusted, the knob 4 can be turned.

[0035] In summary, the present device can close the discharge port 17 through the feeding barrel 11, and drive the feeding barrel 11 to rotate under the action of the driver 8, and let the various feeding troughs 12 of the feeding barrel 11 circulate through the discharge port 17 while rotating, and let the various feeding troughs 12 spread the gravel evenly on the road surface while the storage box 1 moves, which not only ensures the quality of spreading, but also saves manpower. In addition, the storage box 1 also realizes the filtering function under the action of the filter plate 14. The gravel smaller than the aperture of the filter plate 14 can directly enter the feeding trough 12 of the feeding barrel 11 through the filter plate 14, but the gravel larger than the aperture of the filter plate 14 will be affected by the inclination of the filter plate 14 and move from the high point of the filter plate 14 to the lowest point, and enter the collection box 3 through the through groove 15 for collection, which is convenient for the subsequent reprocessing of the intercepted gravel and ensures the normal permeability of the filter plate 14.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
