Technical Field
The invention relates to a road sweeper adopting a horizontal sweeping brush to sweep a road surface, in particular to a centrally-mounted rolling sweeping mechanism for the road sweeper, which is flexible in adjustment of multiple dimensions.
Background
Under the precondition of ensuring the sweeping effect of the sweeping machine, the energy conservation and noise reduction are realized, and the best sweeping effect is always the pursuing direction of the sweeping machine product with the minimum energy consumption and noise cost. The most important subsystem pneumatic system as a sweeping vehicle is a main energy consumption system and a noise source. If the best cleaning effect can be obtained by the minimum air flow, the energy consumption and noise of the pneumatic system are necessarily reduced correspondingly and greatly. In order to ensure enough cleaning width, the main stream products in the domestic market at present adopt a wide suction nozzle to cover the cleaning width, and the disadvantage of the wide suction nozzle is that the inlet air speed must be above a certain value to obtain good cleaning effect, and the required air quantity is high due to the large inlet area of the wide suction nozzle, so that the power requirement and the noise are large.
In order to solve the contradiction between the inlet area of the suction nozzle and the cleaning width, a horizontal rolling and sweeping mechanism is generated. The horizontal rolling broom can collect the garbage in the middle of the road to one side of the road, and a narrow suction nozzle is arranged at the garbage collection position to finish efficient cleaning. In order to obtain a good cleaning effect, the diameter of a rolling broom needs to be ensured to be enough, the position of a transmission shaft in a conventional fuel power chassis is lower, the design space of a rolling broom mechanism is limited, and in addition, the rolling broom mechanism of the existing like products in the market is lack of a self-adaptive function of always keeping parallel with the ground.

Detailed description of the preferred embodiments
The invention will be further described with reference to the following examples (drawings):
as shown in fig. 1 and 2, the central rolling and sweeping mechanism for the road sweeper comprises a rolling and sweeping fixed support (4), rolling and sweeping brushes (5) arranged below the rolling and sweeping fixed support (4) through a driving shaft and a driving motor (6), left and right lateral longitudinal pull rods (8) arranged at the top of the rolling and sweeping fixed support in a parallel manner through hinge shafts and extending forwards, transverse pull rods (2) connected at the front ends of the left and right lateral longitudinal pull rods in a hinged manner, V-shaped supporting rods (7) connected between the left and right lateral longitudinal pull rods (8) in a hinged manner, and a hydraulic cylinder (3) arranged between one lateral longitudinal pull rod of the left and right lateral longitudinal pull rods (8) and the rolling and sweeping fixed support (4); a T-shaped pull rod (1) is arranged at the middle part of the V-shaped support rod (7) in a manner parallel to the left and right lateral longitudinal pull rods (8) through a hinged rotating shaft which is longitudinally arranged, and the hinged rotating shaft is connected with the V-shaped support rod (7) in a hinged manner (see figures 6, 7 and 8); the front end of the T-shaped pull rod (1) is connected with a mounting support on the frame through a rotary hinge shaft, and the T-shaped pull rod (1) supports the front end of the whole rolling and sweeping mechanism and drives the rolling and sweeping mechanism to move forwards in the operation process; the rolling broom comprises a rolling broom fixing support (4), left and right lateral longitudinal pull rods (8) and transverse pull rods (2), wherein the rolling broom fixing support, the left and right lateral longitudinal pull rods and the transverse pull rods form a parallelogram mechanism together, and an included angle between the rolling broom axis and the vehicle running direction is adjusted through the hydraulic oil cylinder (3).
The rolling and sweeping mechanism of the invention has 10 rotating pairs except the hydraulic oil cylinder and the sweeping and brushing rotating shaft, wherein the rotating pair O 1 、O 2 、O 4 、O 5 、O 6 、O 7 、O 8 、O 9 Several parallel revolute pairs cooperate to complete eccentric swing of the parallelogram mechanism so as to realize the cleaning capability enhancement effect of the offset end; during the lifting and descending process of the rolling sweeping mechanism, O is surrounded 3 The rotating pair rotates to drag the rolling and sweeping mechanism to work during the sweeping operation, and one end of the rotating pair is supported and fixedActing; revolute pair O 8 The parallelism between the rolling sweeping mechanism and the ground can be leveled, and no matter in which direction the sweeping brush deflects, the brush wires can be always stuck to the ground without one end of the brush wires being tilted.
The height formed by the rolling broom fixing support (4) and the diameter of the sweeping brush is the lowest space required by the rolling broom mechanism, the space is fully utilized, no other height increasing devices are arranged above the rolling broom fixing support, and when the rolling broom mechanism is lifted and retracted, the phenomenon of interference with the middle transmission shaft can be effectively prevented.
As shown in FIG. 3, a 1 ＝c 1 The distance between the L line and the R line of the innermost boundary line covered by the suction nozzle is b, and the distance is the area which cannot be covered by the suction nozzle, and the cleaning is completed by completely depending on the rolling and sweeping mechanism.
Let r= (a) be assumed in the following expression 1 +b+c 1 )/2
The rolling sweeping mechanism of the invention swings left and right as eccentric, namely the deflection amount of one side is 2 times of that of the other side (see specifically fig. 4 or 5).
As shown in FIG. 4, when the rolling and sweeping mechanism deflects to the right, garbage will accumulate at the position shown on the right side of the rolling and sweeping mechanism, and the overlapping length of the rolling and sweeping brush and the covering surface of the suction nozzle is needed (a in the figure 2 Length shown) is increased to avoid garbage omission, while on the other side (c in the figure) 2 The length shown) can properly reduce the contact ratio of the rolling and sweeping mechanism and the coverage surface of the suction nozzle so as to reduce ineffective sweeping due to no garbage amount accumulation effect. The unequal left-right movement distance of the rolling sweeping mechanism during the rotary swing is realized by setting the eccentricity delta of the rotary center, and the specific implementation mode is as follows. The dimensions described in fig. 4 satisfy the following relation:
the position relation of the rolling and sweeping mechanism is a when the rolling and sweeping mechanism does not swing and rotate yet 1 And c 1 Equal, i.e. a 1 ＝c 1 The method comprises the steps of carrying out a first treatment on the surface of the And each parameter in the above expression satisfies:i.e. overlap length a of the side with larger garbage amount 2 Overlap length c for the side with less garbage 2 Is 2 times as large as the above.
Similarly, as shown in FIG. 5, when the roller broom deflects to the left, refuse will accumulate at the left illustrated position of the roller broom, alpha 2 ＝180°-α 1 Since each parameter satisfies the relation:
then c 3 ＝2a 3 The place with large left pollution can be effectively cleaned.
