As shown in fig. 1 to 4, a first exemplary embodiment of the present utility model provides a roller-tractor device including a bracket 1, a roller-tractor 2, a scraper 3, a sewage box 7, and a pre-tightening mechanism.

The rolling mop 2 is rotatably installed in the bracket 1, the motor drives the rolling mop 2 to work rotationally through a transmission assembly, the transmission assembly can be a belt or a gear set, for example, the motor is installed on the bracket 1 through a transmission box, and the belt or the gear set is located in the transmission box. The roller 2 includes a drum and a fleece covering the outer circumference of the drum. The scraper 3 is slidably mounted on the bracket 1 and its end is movable towards the roller 2. The sewage box 7 is disposed at the rear (i.e., the right as viewed in fig. 4) of the scraper 3 to receive sewage in the scraper 3 pressing the roller 2. The pretensioning mechanism is provided between the bracket 1 and the squeegee 3 so that the squeegee 3 applies a constant pressing force to the peripheral wall of the roller 2.

It can be seen that the roller-hauling device of the present exemplary embodiment enables the squeegee 3 to maintain the pressed state against the roller hauling 2 by utilizing the characteristic that the pretensioning mechanism holds the reset tendency by disposing the pretensioning mechanism between the bracket 1 and the squeegee 3. Therefore, in the use process, even if the rolling mop 2 is worn and the volume is reduced, the position of the scraping plate 3 can be adjusted through the reset of the pre-tightening mechanism, so that the rolling mop 2 is extruded, the sewage residue of the rolling mop 2 is reduced, and the cleaning effect is effectively improved.

In one embodiment, as shown in fig. 4, a pre-tightening mechanism such as a spring is provided pre-compressively between the bracket 1 and the squeegee 3, and since the bracket 1 is fixedly provided, the squeegee 3 is kept pressed down against the upper peripheral wall of the roller 2 by the elastic force of the pre-tightening mechanism, so that the squeegee 3 can be lowered to maintain the pressed state after the roller 2 becomes thinner due to wear. Wherein the upper peripheral wall of the roller 2 may be a peripheral wall located at the upper right of the roller 2 as shown, and the bracket 1 is provided with a water spraying member (not shown) at the upper left of the roller 2 to spray clear water to the roller. Therefore, when the roller mop 2 rotates, the roller mop 2 can generate downward thrust to the scraping plate 3, so that the extrusion force of the scraping plate 3 to the roller mop 2 is enhanced, and the water scraping effect is better.

In one embodiment, a pretensioning mechanism is pretensioned between the bracket 1 and the scraper 3, and the scraper 3 is pressed upwards against the lower peripheral wall of the roller 2 under the action of the elasticity of the pretensioning mechanism. Specifically, one end of a pretensioning mechanism such as a spring is fixedly connected to the bracket 1, and the other end is fixedly connected to the scraper 3 and is provided to extend from above the roller 2 to the lower peripheral wall of the roller 2. Depending on the use requirements, the scraper 3 can be arranged in pressure contact with the lower right peripheral wall of the illustrated roller 2. Similarly, when the roller 2 rotates, the roller 2 can generate downward thrust on the scraping plate 3, so that the extrusion force of the scraping plate 3 on the roller 2 is enhanced, and the water scraping effect is better.

It will be appreciated that the roller 2 can also act as a support for the squeegee 3 when the squeegee 3 is in a downward pressure contact against the upper peripheral wall of the roller 2, and that the support force applied to the squeegee 3 is provided by a pre-tensioned vertical spring structure when the squeegee 3 is in an upward pressure contact against the lower peripheral wall of the roller 2.

In the embodiment shown in fig. 4, the sewage box 7 is provided with a deflector on the side close to the roller 2, which deflector forms the scraper 3. Specifically, the cross section of the baffle in the thickness direction is triangular, in other words, the side of the baffle connected with the sewage box 7 is thinner than the side of the baffle pressed by the roller 2, thereby improving the water squeezing capability of the baffle and the decontamination effect. In addition, the top surface of guide plate is from rolling to dragging 2 to sewage box 7 downward sloping setting for from rolling to dragging 2 extruded sewage and can flow into sewage box 7 under the effect of self gravity, thereby can play automatic dirty effect of collection, and simple structure is favorable to reducing the manufacturing cost of scraper blade 3. The upper portion of the sewage box 7 is open, and the guide plate is connected with one side of the sewage box 7 which is open, and a filter screen with an open sealing cover is arranged on the sewage box 7 so as to filter granular dirt in sewage.

Therefore, the elastic piece 6 can stably stretch and retract vertically by utilizing the limiting function of the guide post 5 on the elastic piece 6. In addition, through the interlude cooperation of guide post 5 and uide bushing 4, can provide horizontal holding power for scraper blade 3 can be steadily along vertical crimping in the perisporium that rolls and drag 2, guarantees the water-scraping effect. The guide sleeve 4 can be positioned in the bracket 1 as shown in the figure, namely one end of the guide sleeve 4 is connected with the bracket 1, and the other end extends into the bracket; or can extend out of the bracket 1, namely one end of the guide sleeve 4 is connected with the bracket 1, and the other end extends out of the bracket.

It should be noted that, the elastic member 6 should set a proper pre-tightening elastic force according to the actual requirement, so as to avoid the problem that the scraper 3 is separated from the roller 2 due to too small elastic force, or the roller 2 is difficult to start due to too large elastic force, and the outer layer flannelette of the roller 2 is seriously sunken.

The guide post 5, the scraping plate 3 and the sewage box 7 are integrally formed, for example, an integral part formed with the guide post 5, the scraping plate 3 and the sewage box 7 can be prepared in a plastic injection molding, sheet metal stamping forming and other modes, so that the overall structural strength can be enhanced, and the water scraping effect and the sewage recovery rate can be improved.
