Reducing roller brush sweeper
The radius that the present invention relates to refuse sweeping machinery, particularly round brush is changeable in running, so that brush is realized unenhanced and swept into total man worker, the full power of slag bucket or the refuse cleaning vehicle that partly manually drives.
At present, a lot of major urban arterial highways all use the bulky refuse road-sweeper.This large-scale cleaning vehicle is generally the full power formula, and is or/and motor is power, underway take motor, motor rotates disk broom or cylinder broom by mechanical device, ground is formed the cleaning of rolling, simultaneously, supporting negative pressure pumping equipment is collected the dust of having swept.This large-scale cleaning vehicle has complex structure, cost is high, price is high, the problem that power consumption is large.As a whole, the brush strut of the round brush of conventional garbage road-sweeper such as Chinese patent literature CN1746430 (to disk broom, cylinder broom should be arranged), CN1624245 (banded disc brush), the disclosed use of CN1776107 (bristle rotating cylinder) is fixed, and the relative ground of round brush is tangent line contact movement (shown in the accompanying drawing 1).
Summary of the invention
Round brush is scalable to change the reducing roller brush sweeper of round brush radius, control cleaning stroke when the purpose of this invention is to provide a kind of the cleaning.
The object of the present invention is achieved like this: a kind of reducing roller brush sweeper, comprise vehicle frame, and be installed in wheel and slag bucket on the vehicle frame, rotating shaft is erected on the vehicle frame, uniformly in the rotating shaft is fixed with a plurality of scalable round brush that are comprised of telescopic pole and brush.
On the above-mentioned vehicle frame guide rail is installed, is fixedly connected with the sliding pin of realizing the brush linear running section of sweeping the floor or the linear running section of sweeping the floor and the target phase that is diagonal up as the gathering sill with guide rail acts on mutually on each telescopic pole.
Above-mentioned slag bucket is arranged on the rear position of brush rotation; Be hinged with slag-guiding plate on the bead before the slag bucket; The control device that also has slag-guiding plate Intermittent Contact ground: linkage one end and slag-guiding plate are hinged, and the other end is positioned at the sphere of action that is installed in the cam in the rotating shaft.
The present invention does following design aspect frame for movement:
1, the brush strut of round brush can stretch, and the flexible change round brush radius by control brush strut can be realized round brush in rotary course:
(1), the operation of brush straightway is swept the floor;
(2), the operation of brush straightway is swept the floor and is swept into slag bucket by the given trace operation.
2, slag-guiding plate kiss the earth and lift built on stilts intermittently.
The linear running section of sweeping the floor of brush and upwards operation sweep into that the slag bucket section can be by guide finger and exclusive guideway be used for realizing.The inventor is by the simulation to the actual scarfing cinder process of sweeping the floor, and ingehious design goes out exclusive guideway; Under the situation of four scalable round brush, matching design goes out to have the cam of four flanges, and a circle is rotated in rotating shaft, and round brush is finished the motion of sweeping the floor for four times, corresponding four the intermittent kiss the earths of slag-guiding plate.Certainly, the number of round brush also can be three or other number.
Compared with prior art, the invention has the beneficial effects as follows:
1, is a kind of fully sweep the floor principle and implementation of innovation.Round brush by guide rail, is realized that brush is parallel to sweep the floor and sweep into the slag bucket action in rotation process, has greatly been improved the cleaning effect.
2, add overhead cam in identical rotating shaft, by linkage slag-guiding plate is intermittently contacted to earth, effectively prevent from shoveling the accumulation of rear rubbish and reduce wearing and tearing to slag-guiding plate.
3, mechanism is light and handy, rationally, and sweeping efficiency is high, and energy consumption is low, can be practically applicable to total man worker and drive, or full power (electronic or motor etc.) drives, or half power drives.
Domestic a lot of major urban arterial highways all use large-scale cleaning vehicle at present, and subsidiary road and some side street lanes are still hand sweeping.The present invention is small and exquisite flexibly, and applicable occasion is many, and institute's energy requirement is little, feasible process, simple, and low cost of manufacture, high efficiency has very large promotional value.

The specific embodiment
In the accompanying drawing, 1, brush; 2, telescopic pole; 3, sliding pin; 4, guide rail; 5, motor; 6, car cover; 7, handspike; 8, trailing wheel; 9, cam; 10, linkage; 11, slag-guiding plate; 12, front-wheel; 13, vehicle frame; 14, slag bucket; 15, slag bucket lid; 16, the brush straight line section of sweeping the floor; 17, sweep into the slag bucket target phase.
Shown in Fig. 5 is that the present invention is the specific design example of half power traction type.Among Fig. 5, wheel is comprised of two front-wheels 12 and two trailing wheels 8; Motor 5 is installed on the vehicle frame 13, and the output shaft of motor connects through shaft coupling with rotating shaft.Be provided with handspike 7 on the vehicle frame 13.
Referring to Fig. 4, this novel vehicle frame 13 that comprises is equipped with slag bucket 14 on the vehicle frame, and rotating shaft is erected on the vehicle frame 13, uniformly in the rotating shaft is fixed with a plurality of scalable round brush that are comprised of telescopic pole 2 and brush 1; Guide rail 4 is installed on the vehicle frame 13, is fixedly connected with on each strut and realizes the brush linear running section of sweeping the floor and the sliding pin 3 that rubbish is swept into the obliquely target phase of slag bucket 14 as acting on mutually with the gathering sill of guide rail 4; Slag bucket 14 is arranged on the rear position that brush rotates (rear of namely travelling); Slag-guiding plate 11 is hinged on the slag bucket 14 front beads, and linkage 10 1 ends and slag bucket are hinged, and the other end of linkage 10 is positioned at the sphere of action of the cam 9 that is installed in the rotating shaft.Scalable round brush is three or four (can be three, four or other number); The corresponding flange that is evenly equipped with three or four rounding ofves on the cam.Linkage 10 is three-link mechanism.Brush 1 is the rectangle brush.Be provided with slag bucket lid 15 on the slag bucket 14, be provided with car cover 6 on the vehicle frame.Two front-wheels 12 and two trailing wheels 8 are installed on the vehicle frame; Motor 5 is installed on the vehicle frame 13, and the output shaft of motor connects through shaft coupling with rotating shaft.
Above-mentioned telescopic pole can be inserted in the cylindrical shell by the built-in spring of cylindrical shell, round bar and consist of.The mounted angle of slag-guiding plate is less than 45 °.
Bead is curved to connect with the ground kiss before the slag-guiding plate, and the slag-guiding plate both sides can fill backplate.
In the round brush rotary course, by stretching of guide rail 4 control telescopic poles 2, the operation of realization brush straightway is swept the floor and on request rubbish is swept into slag bucket.Round brush in rotation, the rotation of band moving cam 9, cam rotarily drive linkage 10 motions, make slag-guiding plate 11 when sweeping into rubbish the end near ground, built on stilts At All Other Times.In this example: round brush is by driven by motor, and car body is by Manual-pushing.In addition, it can be designed to full power formula or full manual mode (namely manually by handle rotating shaft is rotated and realize cleaning) entirely.
Other embodiment explanation: only need the guide groove of guide rail is made respective design, can be under the mating reaction of sliding pin, make brush in a rotation period, realize a linear running section of sweeping the floor or realize a linear running section of sweeping the floor after add a purpose that bits is swept into the obliquely target phase of slag bucket.
Bits are swept into slag bucket except adopting the slag-guiding plate mode, also can adopt other suction.
