[0028] In specific implementation, the device is hung together with the towing vehicle head for moving the device during asphalt mixture paving by using two pull rings 2;

[0029] A certain amount of asphalt mixture is stored in the storage assembly 4 in the initial state, which can be suitable for small-range asphalt pavement paving. The storage assembly 4, the discharging assembly 5 and the vibrating device 7 are opened, so that the asphalt mixture in the storage assembly 4 enters the discharging assembly 5. Under the action of the operation of the discharging assembly 5, the asphalt mixture goes out of the discharging assembly 5 and is horizontally paved on the ground;

[0030] During paving, the device continuously moves forward, the flattening assembly 6 then flattens the paved asphalt mixture, and the vibrating device 7 then completes the vibration and rolling of the asphalt mixture;

[0031] When the paving of the asphalt mixture is stopped for a long time, if there is still remaining asphalt mixture in the storage assembly 4, the discharging channel of the storage assembly 4 is closed, and the storage assembly 4 is operated to heat the asphalt mixture therein, so that the asphalt mixture can be continuously used in the subsequent paving.

[0032] Specifically, in order to prevent the temperature of the asphalt mixture from being reduced and unable to be used when the paving of the asphalt mixture is stopped in low-temperature weather, refer to Figure 3The storage assembly 4 comprises a fixing frame 41 fixedly connected with the middle part of the upper end of the fixing plate 3, an inner surface of the upper fixing frame 41 is fixedly connected with a storage tank 42, an outer surface of the storage tank 42 is fixedly connected with a heating plate 43, a right part of the upper end of the storage tank 42 is fixedly connected with a feeding port 44 penetrating through the storage tank 42, an inner cavity of the storage tank 42 is provided with a stirring assembly, and a lower end of the storage tank 42 is fixedly connected with a discharging component 46 penetrating through the storage tank 42.

[0036] In the specific implementation, a proper amount of asphalt mixture is added into the storage tank 42 to provide raw materials for small-range asphalt pavement paving, and the discharging component 46 is opened to enable the asphalt mixture in the storage tank 42 to enter the discharging assembly 5.

[0037] When the construction personnel rest, eat or sudden rainfall causes the asphalt mixture to be unable to be paved, if a certain amount of asphalt mixture is still stored in the storage tank 42, the discharging component 46 is closed to prevent the asphalt mixture in the storage tank 42 from entering the discharging assembly 5.

[0038] The heating plate 43 is powered and a suitable heating temperature is set, so that the heating plate 43 can heat the asphalt mixture in the storage tank 42, prevent long-term shutdown, cause the temperature of the asphalt mixture to decrease, and cause waste, and avoid using asphalt mixture with unsuitable temperature for paving, so that the asphalt mixture cannot be rolled or rolled to the position, and the quality of the rolled asphalt pavement does not meet the requirements;

[0043] The motor two 52 is started to drive the spiral conveying rod 53 to rotate forward, and the asphalt mixture in the cylinder 51 is discharged from the discharge ports 54; the spiral conveying rod 53 rotates to convey the asphalt mixture entering the cylinder 51 from right to left, so that the asphalt mixture discharged from the cylinder 51 is evenly spread in the transverse direction, instead of being spread all at once, so that the asphalt mixture is piled up, and the subsequent vibration of the vibration device 7 on the asphalt mixture is affected;

[0044] When the device continuously spreads the asphalt mixture forward, the scraper 62 scrapes the asphalt mixture forward, so that the asphalt mixture is scraped flat;

[0045] At this time, the four springs 631 on the same side are compressed under the force, and the reaction force of the four springs 631 makes the force of the scraper 62 on the asphalt mixture greater, so as to further facilitate the subsequent vibration of the vibration device 7 on the asphalt mixture;

[0046] The spring assembly 63 is symmetrically arranged on the front and back sides, so that the scraper 62 can move forward or backward to scrape the asphalt mixture flat, thereby facilitating the paving work of the asphalt mixture by the worker;

[0047] The telescopic rod 632 can provide horizontal support for the spring 631, so that the scraper 62 does not shake when the spring 631 is deformed under the force

[0048] At the same time, the vibration device 7 is started to vibrate and compact the asphalt mixture scraped by the scraper 62.

[0049] It should be particularly noted that the specific installation mode of the storage tank 42, the motor one 451, the motor two 52 and the vibration device 7, the connection mode of the circuit and the control method all belong to conventional design, and the utility model will not be described in detail.

[0050] The working principle of the utility model is:

[0051] When the paving of the asphalt mixture is stopped for a long time and a certain amount of asphalt mixture is still stored in the storage tank 42, the discharge part 46 is closed, the heating plate 43 is powered on and a suitable heating temperature is set, so that the heating plate 43 heats and insulates the asphalt mixture in the storage tank 42, and the motor one 451 is started to drive the rotating rod 452 to rotate, so as to drive the three stirring plates 453 to rotate and stir the asphalt mixture in the storage tank 42;

[0052] When the asphalt mixture is spread, the device is hung with the towing vehicle by two pull rings 2, the discharging part 46 is opened, the asphalt mixture in the storage tank 42 enters the cylinder 51, the motor 52 is opened to drive the spiral conveying rod 53 to rotate in the positive direction, the asphalt mixture in the cylinder 51 is conveyed from right to left, and the asphalt mixture is uniformly spread out from the several discharging ports 54;

[0053] The scraper 62 then scrapes the asphalt mixture out of the cylinder 51 forward by the force of the continuous forward movement of the device, so as to scrape the asphalt mixture flat, and the vibration device 7 is opened to run and then vibrates and rolls the asphalt mixture.
