In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0025] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0027] like Figure 1 and Figure 2 The device for cleaning and collecting bulk materials in front of a paver track shown in the figure comprises: a cleaning device 1, a cleaning device support frame 3, a collecting box 6, a steel column 7 and a fixing device, wherein the steel column 7 is arranged on a crawler frame 8, and steel columns 7 are respectively arranged on both sides of the crawler frame 8, one end of the cleaning device support frame 3 arranged in pairs is connected to the cleaning device 1, and the other end of the cleaning device support frame 3 is connected to the steel column 7, and a fixing device is arranged at the connection between the cleaning device support frame 3 and the steel column 7, the collecting box 6 is located on either side of the cleaning device 1, and bolts are arranged at the connection between the collecting box 6 and the cleaning device 1.

[0028] The above-mentioned bulk material cleaning and collecting device in front of the paver track can promptly clean up the scattered materials that are prone to segregation and other unqualified materials through the cleaning device 1, so as to avoid unqualified quality acceptance and reduce the increased costs caused by rework and delays. At the same time, the bulk material is collected by the detachable collection box 6 connected by bolts. At the same time, the collected bulk material can be used for paving other roads and construction of other parts of the project, which is conducive to reuse.

[0029] like Figure 1 and Figure 2 As shown, in this embodiment, the device also includes a shielding device 2, which is located above the cleaning device 1. The horizontal angle between the shielding device 2 and the track frame 8 is 45°.

After the steel column 7 is placed in the U-shaped groove of the U-shaped fixing card 4 and the position is adjusted, the U-shaped fixing card 4 is tightened and fixed using the bolt 5. The detachable design helps to adjust the angle of the cleaning device support frame 3 and the cleaning device 1, thereby increasing the practicality of the device.

[0032] like Figure 1 and Figure 2 As shown, in this embodiment, the steel column 7 is welded to the crawler frame 8, and the cleaning device 1 is welded to the cleaning device support frame 3. The cleaning device support frame 3 is welded by square steel pipes. The cleaning device 1 is composed of two cleaning plates perpendicular to each other, and the cleaning plates are steel plates with a thickness of 5 mm. Welding helps to improve the stability of the connection. The welding structure has high rigidity and good integrity, which helps the device to collect bulk materials while ensuring the structural stability of the device.

[0033] like Figure 1 and Figure 2 As shown, in this embodiment, when in use, the paver moves forward, and at the same time, the steel column 7 is placed in the U-shaped groove of the U-shaped fixing card 4 and after adjusting the position, the U-shaped fixing card 4 is tightened and fixed with the bolt 5, and then the cleaning device 1 is used to collect the scattered bulk material, and the front end of the cleaning device 1 is in contact with the ground, and the bulk material is collected on the cleaning device 1, and then the bulk material is manually moved to the collection box 6, and the collection box 6 is removed from the cleaning device 1, and finally the bulk material collected in the collection box 6 is used for paving other roads and construction of other parts of the project; after the collection work is completed, the bolt 5 is loosened, the cleaning device support frame 3 is adjusted, and then the bolt 5 is tightened, and then the cleaning device 1 is raised to avoid affecting the normal operation of the paver.

[0034] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description.
