At least one of the first mounting block 110 and the second mounting block 120 is movable relative to the mounting block 100 to adjust an inclination angle of a connecting line between the mounting hole of the first mounting block 110 and the mounting hole of the second mounting block 120.
As shown in fig. 3, when the brush head of the side brush 200 is at the predetermined position, the brush head needs to maintain an inclination angle, such as 5 to 10 degrees or more, with the ground, where the inclination angle is the predetermined angle between the side brush 200 and the ground. When the preset angle of the side brush 200 and the ground is adjusted, the side brush installation mechanism of this embodiment can move relative to the installation frame 100 through the movable one or both of the first installation block 110 and the second installation block 120, for example, the second installation block 120 can move relative to the installation frame 100, so that the position of the installation hole of the second installation block 120 in the horizontal direction or the inclination angle of the axis of the installation hole of the second installation block 120 relative to the horizontal direction can be changed, and at this time, the inclination angle of the connection line of the installation holes of the first installation block 110 and the second installation block 120 is changed, so that the inclination angle of the side brush rotating shaft 210 installed at the position of the installation hole of the second installation block 120 can also be changed, and the purpose of adjusting the inclination angle of the side brush 200 relative to the ground can be achieved. This embodiment limit brush installation mechanism is when adjusting an installation piece, and another installation piece need not move about, and the main load member of brush head this moment can be regarded as to the installation piece of inactive to do not need the handheld limit brush of operating personnel or dismantle the limit brush from installation mechanism, simple structure, and convenient operation is convenient, and the regulation efficiency improves.
It is understood that at least one of the first mounting block 110 and the second mounting block 120 is movable relative to the mounting block 100, i.e. the first mounting block 110 is movable relative to the mounting block 100 and the second mounting block 120 is stationary; alternatively, second mounting block 120 may be movable relative to mounting block 100, with first mounting block 110 stationary; or both the first mounting block 110 and the second mounting block 120 may be movable with respect to the mounting block 100. When the first mounting block 110 and the second mounting block 120 can move relative to the mounting block 100, the horizontal position of the mounting holes on the first mounting block 110 and the second mounting block 120 can be changed by moving in the horizontal direction, so that the inclination angle of the connecting line of the two mounting holes is changed, for example, when the first mounting block 110 is not moved, when the second mounting block 120 is at the first position, the mounting holes of the first mounting block 110 and the mounting holes of the second mounting block 120 are vertically aligned, at this time, the connecting line of the mounting holes of the first mounting block 110 and the mounting holes of the second mounting block 120 is vertical, the rotating shaft 210 of the side brush installed in the mounting holes is vertical, and the brush head of the side brush installed on the rotating shaft 210 is approximately horizontally arranged; the second mounting block 120 is horizontally moved to the right direction, so that the mounting hole of the second mounting block 120 is dislocated with the mounting hole of the second first mounting block 110, at the moment, the connecting line of the mounting hole of the first mounting block 110 and the mounting hole of the second mounting block 120 is in an inclined arrangement, at the moment, the rotating shaft 210 of the side brush is in an inclined arrangement, and the brush head of the side brush is also in an inclined arrangement. Naturally, the movement of the first mounting block 110 and the second mounting block 120 relative to the mounting block 100 may also be to change the orientation of the mounting holes thereon by rotating, for example, the first mounting block 110 and the second mounting block 120 may both rotate on a horizontal axis, and at the first position, the mounting holes of the first mounting block 110 and the second mounting block 120 may be in an up-down facing manner, and at this time, the rotating shaft 210 of the edge brush is in a vertical state; in the second position, the first mounting block 110 and the second mounting block 120 rotate in the same direction by the same angle around a horizontal axis (the horizontal axis can be understood as an axis perpendicular to the axis direction of the mounting hole), the axes of the mounting hole of the first mounting block 110 and the mounting hole of the second mounting block 120 are still consistent, but the axes of the mounting holes are inclined relative to the horizontal plane, the rotating shaft 210 of the side brush is correspondingly inclined, and the angle of the brush head of the side brush is adjusted.
It should be noted that one or both of the first and second mounting blocks 110, 120, which are movable, should be able to be fixed relative to the mounting block 100 when moved or rotated into position. In other words, at least one of the first mounting block 110 and the second mounting block 120 is movable relative to the mounting block 100, that is, the first mounting block 110 and/or the second mounting block 120 has a plurality of mounting positions on the mounting block 100, and one or both of the plurality of mounting positions can be switched between the corresponding plurality of mounting positions, and the rotating shaft 210 of the side brush can have different inclination angles in different mounting positions.

In correspondence to the side brush rotating shaft 210 in this embodiment, the side brush mounting mechanism is a form in which the second mounting block 120 is movable relative to the mounting block 100, and the first mounting block 110 is fixedly disposed. It will be appreciated that the second mounting block 120 is capable of rotating or moving to change the angle of inclination of the lower section 212 of the shaft 210 for the purpose of adjusting the angle of the brush head of the side brush.

Similarly, the installation angle of the first installation block 110 relative to the first installation plate 131 can be conveniently observed through the first side surface 111 of the first installation block 110.
In view of the movable manner of the second mounting block 120 of the side brush mounting mechanism of the present embodiment, the second mounting block 120 of the present embodiment is connected to the first mounting plate 131 through the second mounting plate 132, the plate surface of the second mounting plate 132 is perpendicular to the plate surface of the first mounting plate 131, and the first mounting block 110 and the second mounting block 120 are disposed on the same side of the second mounting plate 132, that is, the side surface of the first mounting plate 131 where the first mounting block 110 is disposed faces the side surface of the second mounting plate 132 where the second mounting block 120 is connected, in other words, the first mounting block 110 and the second mounting block 120 are disposed in the same area where the first mounting plate 131 and the second mounting plate 132 are cross-connected and divided into a plurality of areas.

In an alternative manner, the second mounting plate 132 may have a plurality of mounting positions on the first mounting plate 131, and the second mounting plate 132 can be switched among the plurality of mounting positions and can be fixed after being switched in place, and when the second mounting plate 132 is at different mounting positions, the angle of the second mounting plate 132 to the horizontal plane is different, so that the axial direction of the mounting hole of the second mounting block 120 is changed by switching the second mounting plate 132 at different mounting positions. For example, the mounting hole of the first mounting block 110 is vertically disposed, and when the mounting hole of the second mounting block 120 needs to be inclined to one side with respect to the first mounting hole, the plate surface of the second mounting plate 132 may be adjusted to be inclined to the horizontal plane. As shown in fig. 3, the second mounting plate 132 is inclined toward the first mounting block 110, and the brush head is formed in an inclined manner. Specifically, the detachable connection between the first mounting plate 131 and the second mounting plate 132 may be a snap connection, a bolt connection, or the like.
