Referring to fig. 7 and 8, the brush head 40 includes a connecting member 41, a base 42, a first sub-brush head 43 and a second sub-brush head 44, wherein the connecting member 41 is fixedly mounted at one end of the rotating shaft 21; the connecting member 41 is substantially cylindrical, one end of which is sleeved on one end of the rotating shaft 21, and a screw or a bolt is inserted through the connecting member 41 to screw the side wall of the connecting member 41 into one end of the rotating shaft 21, so that the connecting member 41 is fixedly connected with the rotating shaft 21. The other end of the connecting member 41 is fixedly mounted on a surface of the base 42. The other surface of the base 42 is recessed inwards to form a receiving space 42, a connecting hole 422 is formed in the bottom surface of the receiving space 421, and a sliding groove 423 is formed in the side surface of the receiving space 421. The slide groove 423 is provided along the axial direction of the rotary shaft 21. The first sub-brush head 43 comprises a connecting portion 431, a first fixing portion 432 and first bristles 433, wherein the connecting portion 431 is cylindrical, one end of the connecting portion is fixedly connected with the first fixing portion 432, and the other end of the connecting portion is provided with a clamping block 4311.

A groove 4312 is arranged on an end face of the connecting portion 431, the groove 4312 is used for accommodating the protruding portion, the protruding portion can rotate in the groove 4312, and one end of the push rod 11 can be prevented from sliding out of the groove 4312. In other embodiments, in order to improve the fluency of the mutual rotation between the push rod 11 and the connecting portion 431, a bearing is provided between the groove 4312 and the push rod 11, and the protrusion is engaged with the bearing, so that the bearing can be prevented from sliding out of the push rod 11. The second sub-brush head 44 includes a second fixing portion 441 and second bristles 442, the second fixing portion 441 rotates in a circular shape, one surface of the second fixing portion 441 is fixedly mounted on one surface of the base 42, an inner side surface and an outer side surface of the second fixing portion 441 are both conical surfaces, and the inner side surface of the second fixing portion 441 corresponds to and is matched with the side surface of the first fixing portion 432. One end of the second brush 442 is fixed to the outer side surface of the second fixing portion 441. The second fixing portion 441 is made of an elastic material. The side surface of the first fixing portion 432 abuts against the inner side surface of the second fixing portion 441. When the first brush head 43 extends along the axis of the second brush head 44, the side surface of the first fixed portion 432 presses the inner side surface of the second fixed portion 441 outwards, and the second fixed portion 441 is made of elastic material such as rubber, and is elastically deformed under the pressing, and the second fixed portion 441 opens outwards, so that the bristles fixed to the second fixed portion 441 are scattered around, thereby increasing the cleaning range of the whole brush head assembly 100.
The other end of the first sub-brush head 43 is surrounded by the second sub-brush head 44, and the first sub-brush head 43 can move relative to the second sub-brush head 44 along the axis of the second sub-brush head 44 under the driving of the push rod 11 of the first driving device 10 (i.e. the first sub-brush head 43 can complete the telescopic action relative to the second sub-brush head 44). The second driving device 20 can drive the brush head 40 to rotate through the rotating shaft 21.
In the process of actually using the sweeper with the brush head assembly 100, when the sweeper detects that the ground of an area to be cleaned is smooth and flat and has no rubbish such as sand and soil which is difficult to clean, only the second sub-brush head 44 is in contact with the ground, and the second bristles 442 of the second sub-brush head 44 are longer and softer than the first bristles 433 of the first brush head 43, so that on one hand, the abrasion of the bristles can be reduced, the service life is prolonged, on the other hand, the resistance in rotation can be reduced, and more energy is saved. When the sweeper detects that the ground of an area to be cleaned is uneven or when garbage such as sand and soil difficult to clean exists, the first sub brush head 43 can be driven by the push rod 11 of the first driving device 10 to extend out along the axis of the second sub brush head 44, and the cleaning end of the first brush bristles 433 is basically equal to the cleaning end of the second brush bristles 442. Because the first bristles 433 are shorter and harder than the second bristles 442, when the first sub-brush head 43 and the second sub-brush head 44 work together, the sweeping force and intensity are higher, and thus, garbage such as sand and dust which is difficult to be cleaned can be swept cleanly.
Further, the side surface of the first fixing portion 432 presses the inner side surface of the second fixing portion 441 outwards, and the second fixing portion 441 is made of an elastic material and elastically deforms under the pressing, so that the second fixing portion 441 opens outwards, and the bristles fixed to the second fixing portion 441 are scattered around, thereby increasing the cleaning range of the entire brush head assembly 100. When the first sub-brush head 43 extends along the axis of the second sub-brush head 44, the side surface of the first fixed portion 432 presses the inner side surface of the second fixed portion 441 outwards, and the second fixed portion 441 is made of an elastic material and elastically deforms under the pressing, and the second fixed portion 441 opens outwards, so that the bristles fixed to the second fixed portion 441 spread outwards, thereby increasing the cleaning range of the whole brush head assembly 100. The inner side surface of the second fixing portion 441 is extruded outwards by the side surface of the first fixing portion 432, the second fixing portion 441 is made of an elastic material and is elastically deformed under extrusion, the second fixing portion 441 stretches outwards, so that bristles fixed on the second fixing portion 441 are dispersed around, and after the inclination of the second bristles 442 is larger, the cleaning range can be expanded in the horizontal direction, and a corner between a wall foot or a road edge and the ground can be cleaned more easily, so that the cleaning effect of the sweeper when the wall foot or the road edge is cleaned is better.
Compared with the prior art, the brush head provided by the utility model comprises a base, a connecting piece, a first sub brush head and a second sub brush head. The connecting piece is fixedly arranged on the base, one end of the first sub-brush head is arranged on the base and can move relative to the base along the rotation axis of the base, the second sub-brush head is fixedly arranged on the base, and the hardness of the bristles of the first sub-brush head is greater than that of the bristles of the second sub-brush head. By the mode, when the flat ground needs to be cleaned, only the second sub-brush head with the softer bristles is needed, so that the abrasion of the bristles is reduced, and the service life is prolonged; when the ground that the topography is comparatively complicated or unevenness needs to be cleaned, first son brush head is stretched out in by the base, with the contact of second son brush head common with ground, the brush hair of first son brush head is shorter and hard, can provide bigger dynamics of cleaning to promote and clean the effect.
Another embodiment of the utility model provides a sweeper truck, which is provided with the brush head assembly.
Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; within the idea of the utility model, also technical features in the above embodiments or in different embodiments may be combined, steps may be implemented in any order, and there are many other variations of the different aspects of the utility model as described above, which are not provided in detail for the sake of brevity; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
