Detailed ways

The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

As shown in FIGS. 1 to 7 , an embodiment of the present invention provides a side brush installation mechanism, including an installation frame 100 . The installation frame 100 is provided with a first installation block 110 and a second installation block 120 up and down in sequence. The first installation block 110 and the second mounting block 120 are provided with mounting holes, and the mounting holes are used for mounting the rotating shaft 210 of the side brush. At least one of the first mounting block 110 and the second mounting block 120 can move relative to the mounting frame 100 to adjust the inclination angle of the line connecting 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 in its preset position, it needs to maintain an inclination angle between the brush head and the ground, such as 5-10 degrees, or a higher degree, and the inclination angle is the angle between the side brush 200 and the ground. The preset angle of the ground. When adjusting the preset angle between the side brush 200 and the ground, the side brush mounting mechanism of this embodiment moves relative to the mounting frame 100 through the movable one or both of the first mounting block 110 and the second mounting block 120 . The two mounting blocks 120 can move relative to the mounting frame 100, so that the position of the mounting hole of the second mounting block 120 in the horizontal direction or the inclination of the axis of the mounting hole of the second mounting block 120 relative to the horizontal direction is changed. The inclination angle of the line connecting the mounting holes of the block 110 and the second mounting block 120 changes, so that the inclination angle of the side brush rotating shaft 210 installed at the mounting hole of the second mounting block 120 also changes, so as to adjust the side brush. 200 is the purpose of the tilt angle relative to the ground. When the side brush installation mechanism of this embodiment adjusts one installation block, the other installation block does not need to move, and the inactive installation block can be used as the main bearing member of the brush head at this time, so that the operator does not need to hold the side brush or move the side brush. The brush is disassembled from the installation mechanism, the structure is simple, the operation is convenient and convenient, and the adjustment efficiency is improved.

It can be understood that at least one of the first mounting block 110 and the second mounting block 120 can move relative to the mounting frame 100 , that is, the first mounting block 110 can move relative to the mounting frame 100 while the second mounting block 120 is fixed. Or, the second installation block 120 can move relative to the installation frame 100, and the first installation block 110 is fixed; or both the first installation block 110 and the second installation block 120 can move relative to the installation frame 100. Wherein, when the first mounting block 110 and the second mounting block 120 can move relative to the mounting frame 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, thereby making the connection between the two mounting holes. When the inclination angle changes, for example, when the first mounting block 110 does not move and the second mounting block 120 is in the first position, the mounting holes of the first mounting block 110 and the mounting holes of the second mounting block 120 are aligned up and down. The connection line between the installation hole of the first installation block 110 and the installation hole of the second installation block 120 is vertical, the rotating shaft 210 of the side brush installed in the installation hole is vertical, and the side brush installed on the rotating shaft 210 is vertical. The brush head is arranged approximately horizontally; the second mounting block 120 is moved horizontally to the right, so that the mounting hole of the second mounting block 120 and the mounting hole of the second first mounting block 110 are misaligned. The connection line between the installation hole and the installation hole of the second installation block 120 is inclined. At this time, the rotating shaft 210 of the side brush is inclined and the brush head of the side brush is inclined. Naturally, the movement of the first mounting block 110 and the second mounting block 120 relative to the mounting frame 100 may also be performed by changing the orientation of the mounting holes thereon by rotating. For example, both the first mounting block 110 and the second mounting block 120 may be horizontal In the first position, the mounting holes of the first mounting block 110 and the second mounting block 120 may be vertically facing each other. At this time, the rotating shaft 210 of the side brush is in a vertical state; when in the second position , the first mounting block 110 and the second mounting block 120 are rotated around the horizontal axis (the horizontal axis can be understood as an axis perpendicular to the axis of the mounting hole) toward the same direction and by the same angle. At this time, the mounting hole of the first mounting block 110 and the The axes of the mounting holes of the two mounting blocks 120 are still the same, but the axes of the mounting holes are inclined relative to the horizontal plane, the rotating shaft 210 of the side brush is inclined accordingly, and the angle of the brush head of the side brush is adjusted.

It should be noted that, when the movable one or both of the first mounting block 110 and the second mounting block 120 are moved or rotated in place, they should be able to be relatively fixed to the mounting frame 100 . In other words, at least one of the first mounting block 110 and the second mounting block 120 can move relative to the mounting rack 100 , that is, the first mounting block 110 and/or the second mounting block 120 have multiple mounting positions on the mounting rack 100 , and one or both of the multiple installation positions can be switched between the corresponding multiple installation positions, and in different installation positions, the rotating shaft 210 of the side brush can have different inclination angles.

In practical applications, the rotating shaft 210 of the side brush should be able to rotate relative to the first mounting block 110 and the second mounting block 120 to drive the brush head operation. In order to facilitate the installation of the rotating shaft 210, the first mounting block of the side brush mounting mechanism in this embodiment The corresponding mounting holes of the 110 and the second mounting block 120 are respectively mounted with bearings through the bearing seat, and the rotating shaft 210 is mounted in the bearings.
