When preparing the pavement patching material: firstly, adhering modified asphalt with a certain thickness on the upper surface and the lower surface of a tire base fabric; then, rolling the base fabric adhered with the modified asphalt into an asphalt thin strip 5 by using a rolling component; during the operation of the rolling assembly, the conveying assembly drives the rolled thin asphalt strip 5 to move towards the cutting assembly. The spreading assembly spreads the crushed stone 6 onto the thin strip of asphalt 5 as the thin strip of asphalt 5 moves toward the cutting assembly. The thin asphalt strip 5 on which the crushed stones 6 are spread can be cut into pavement repair materials of a designated length when passing through the cutting assembly.
Therefore, the device has a simple structure and is convenient to operate, and the rolling assembly, the spreading assembly and the conveying assembly are associated by utilizing the conveying assembly, so that the continuous operation of the rolling procedure, the spreading procedure and the cutting procedure can be realized, and the rapid and continuous preparation of the pavement patching material is further realized.
As shown in fig. 2, the rolling component comprises an upper roller 1.1, a lower roller 1.2, a mounting frame and a driving piece, wherein the upper roller 1.1 and the lower roller 1.2 are both fixed on the mounting frame, the upper roller 1.1 is arranged above the lower roller 1.2, a rolling gap is formed between the upper roller 1.1 and the lower roller 1.2, and the height of the rolling gap is equal to the thickness of the thin asphalt strip 5; the driving piece is used for driving the upper roller 1.1 and the lower roller 1.2 to rotate reversely. Since the thickness of the base fabric adhered with the modified asphalt is larger than the height of the rolling gap between the roller and the lower roller 1.2, when the base fabric adhered with the modified asphalt passes through the rolling gap, the base fabric adhered with the modified asphalt is rolled into the thin asphalt strip 5 along with the reverse rotation of the upper roller 1.1 and the lower roller 1.2.
In consideration of the different thicknesses of pavement patching materials required by different pavement diseases, the height of the rolling gap is adjustable in order to further expand the application range of the device, wherein the height of the rolling gap is preferably 4 mm-1 cm.
It should be noted that there are various ways to achieve the adjustable height of the rolling gap, for example: in the first mode, a plurality of mounting holes are formed in the two sides of the mounting rack along the height direction of the mounting rack, and the mounting holes are used for inserting the rotating shaft for installing the roller 1.1. During the installation, the staff can be according to the mounting position of roller 1.1 in the height adjustment of required rolling clearance, that is to say, insert the pivot both ends of going up roller 1.1 and establish in the mounting hole of corresponding height to increase or reduce the interval between roller 1.1 and the lower roller 1.2. Mode two, the both sides of mounting bracket all are equipped with the slide rail that extends along its direction of height, go up the both ends of roller 1.1's pivot respectively through slider and the slide rail sliding connection who corresponds, the top of mounting bracket is equipped with the cylinder, and the piston rod and the slider of cylinder are connected, and the piston rod in the cylinder drives the slider through flexible and reciprocates, and then realizes the relative altitude mixture control of roller 1.2 down of roller 1.1.
In addition, the driving components for driving the upper roller 1.1 and the lower roller 1.2 to rotate reversely can also adopt various structural forms, such as:
form one, driving piece include roll motor, driving gear and with driving gear engaged with driven gear, on the driving gear was fixed in the pivot of last roller 1.1, driven gear was fixed in the pivot of lower roller 1.2, roll the motor and be connected with the pivot of last roller 1.1 for the pivot of drive roller 1.1 rotates. Therefore, when the base fabric adhered with the modified asphalt needs to be rolled, the rolling motor is started. Taking fig. 2 as an example, when the rolling motor drives the upper roller 1.1 to rotate counterclockwise, the driving gear fixed on the rotating shaft of the upper roller 1.1 rotates counterclockwise together with the upper roller. Because the driving gear is meshed with the driven gear, the driving gear can drive the driven gear to rotate clockwise, and the driven gear is fixed on the rotating shaft of the lower roller 1.2, so that the lower roller 1.2 can be driven to rotate clockwise. Therefore, the upper roller 1.1, the driving gear, the driven gear and the lower roller 1.2 move synchronously, the driving gear and the driven gear are used for driving the upper roller 1.1 and the lower roller 1.2 to rotate reversely, and the tire base cloth adhered with the modified asphalt is rolled.
Secondly, as shown in fig. 1, the driving member comprises a first rolling motor 1.3 and a second rolling motor 1.4, and the first rolling motor 1.3 is connected with the rotating shaft of the upper roller 1.1 and is used for driving the rotating shaft of the upper roller 1.1 to rotate; the second rolling motor 1.4 is connected with the rotating shaft of the lower roller 1.2 and is used for driving the rotating shaft of the lower roller 1.2 to rotate. Therefore, when the tire base cloth adhered with the modified asphalt needs to be rolled, the first rolling motor 1.3 and the second rolling motor 1.4 are started simultaneously, the first rolling motor 1.3 drives the upper roller 1.1 to rotate anticlockwise, and the second rolling motor 1.4 drives the lower roller 1.2 to rotate clockwise.
Of course, compared with the second mode, the first mode only needs one motor, and the synchronous rotation of the upper roller 1.1 and the lower roller 1.2 can be ensured.
As shown in fig. 1, conveying assembly includes action wheel 2.1, follows driving wheel 2.2, drive belt 2.3 and conveying motor 2.4, follows driving wheel 2.2 and closes on the subassembly setting that rolls, and action wheel 2.1 closes on the cutting unit setting, and action wheel 2.1 passes through drive belt 2.3 transmission with following driving wheel 2.2 to be connected, and conveying motor 2.4 is connected with action wheel 2.1 for drive action wheel 2.1 rotates. After the conveying motor 2.4 is started, when the pavement patching material is just prepared, a worker can manually pull and place the asphalt thin strip 5 which is rolled by the rolling assembly on the conveying belt 2.3. The belt 2.3 then pulls the thin strip 5 towards the cutting assembly by friction.
As shown in fig. 2, the spreading assembly comprises a storage hopper 3.1 and a valve, the storage hopper 3.1 is suspended above the conveying assembly, a discharge port is arranged on the bottom surface of the storage hopper 3.1, and the discharge port is provided with the valve. When the asphalt strip 5 reaches below the storage hopper 3.1, the operator can open the valve. At this point, the crushed stone 6 placed in the storage hopper 3.1 in advance is spilled through the discharge port onto the asphalt strip 5 below. Because the asphalt thin strip 5 is driven by the conveying assembly to continuously move towards the cutting assembly, the crushed stone 6 is spread on the part of the asphalt thin strip 5 passing through the storage hopper 3.1. Wherein, the gravel 6 can adopt graded gravel.
Of course, in order to reduce the discharge amount of the storage hopper 3.1 per unit time, the storage hopper 3.1 is gradually reduced from top to bottom. For example, the projection of the storage hopper 3.1 on a vertical plane may be in the shape of an inverted cone or an inverted pyramid. In addition, in order to avoid that part of the crushed stones 6 are stuck at the discharge port, the side wall of the storage hopper 3.1 is provided with a vibration motor. When the vibration motor is started, the storage hopper 3.1 can be driven to vibrate along with the vibration motor, and then the broken stones 6 in the storage hopper are driven to be discharged out of the discharge hole.
As shown in fig. 1, the cutting assembly includes a knife holder 4.1 and a knife switch 4.2, the knife switch 4.2 and the knife holder 4.1 are respectively disposed on the upper and lower sides of the asphalt thin strip 5, and one end of the knife switch 4.2 is rotatably connected to the knife holder 4.1. When the length of the asphalt thin strip 5 passing through the upper part of the cutter seat 4.1 reaches a specified length, a worker can pull down the gate blade 4.2 to cut off the asphalt thin strip 5, and the cut asphalt thin strip 5 is the pavement patching material.
