Description

Technical Field

[0001] The present application relates to the field of floor cleaning equipment, and in particular to a floor scrubber capable of automatically adjusting the height of a scraping belt. Background Art

[0002] A floor scrubber is a cleaning device suitable for a variety of floors. Its main operating modes are hand-push and ride-on. The whole machine is driven by a battery DC. It efficiently cleans the floor through the front and rear brush plates and water-absorbing rakes. At the same time, the scraper belt scrapes away the water left on the bottom during the cleaning process.

[0003] With respect to the above-mentioned related technologies, the inventors believe that: when the scraper belt is scraping water, friction is generated between the scraper belt and the ground. As the use time increases, the bottom end of the scraper belt is worn, and a gap is generated between the bottom end of the scraper belt and the bottom surface, resulting in a reduction in the scraping effect of the scraper belt. Summary of the invention

[0004] In order to achieve automatic adjustment of the scraping belt height, thereby ensuring the scraping effect of the scraping belt, the present application provides a floor scrubber that automatically adjusts the scraping belt height.

[0005] The present application provides a floor scrubber with automatic adjustment of scraper belt height, which adopts the following technical solution:

[0006] A floor scrubber with automatic adjustment of scraper belt height comprises a floor scrubber body and a brush disc, the bottom of the floor scrubber body is fixedly connected to a disc cover, the brush disc is rotatably connected in the disc cover, connecting components are provided on opposite sides of the disc cover, and each connecting component is provided with a mounting component on the side facing away from the disc cover, a height adaptive component is connected between the connecting component and the mounting component, the mounting component can be lowered along the height adaptive component by its own weight, and the mounting component is connected to the scraper belt that contacts the ground; the height adaptive component comprises a sliding rod, a positioning plate is fixedly connected to the mounting component, the sliding rod is vertical and passes through the connecting component, the positioning plate and the mounting component at the same time, a limiting cap for preventing the mounting component from falling off the sliding rod is fixedly connected to the top of the sliding rod, the bottom end of the sliding rod passes through the positioning plate and is connected to a fastener, and the sliding rod is slidably connected to the mounting component, the connecting component and the positioning plate.

[0007] By adopting the above technical solution, as the scraper belt wears out over time, the mounting assembly can descend along the height adaptive assembly by its own weight until the scraper belt touches the ground again, thereby realizing automatic adjustment of the scraper belt height, ensuring the wiping effect, and extending the service life of the scraper belt.

DETAILED DESCRIPTION

[0035] The following is combined with Figure 1-8 This application is described in further detail.

[0036] The present application embodiment discloses a floor scrubber that automatically adjusts the scraper belt height. Figure 1 A floor scrubber with automatic adjustment of scraper belt height includes a floor scrubber body 1, a front wheel 101 is rotatably connected to one side of the wide side of the bottom surface of the floor scrubber body 1, and a mounting sleeve 102 is fixedly connected to the other side. The length direction of the mounting sleeve 102 is in the same direction as the width direction of the floor scrubber body 1.

[0037] Reference Figure 1The mounting sleeve 102 is provided with a mounting rod 1021, which is rotatably connected to the mounting sleeve 102 through a bearing. The rear wheels 103 are fixedly mounted on both ends of the mounting rod 1021, and the axis of the rear wheel 103 is coaxial with the axis of the mounting rod 1021, and the axis of the front wheel 101 and the axis of the rear wheel 103 are parallel to each other.

[0038] Reference Figure 1 The bottom surface of the floor scrubber body 1 is fixedly connected with a vertically arranged connecting column 104, and the connecting column 104 is located between the front wheel 101 and the rear wheel 103. The bottom of the connecting column 104 is connected with a disc cover 2, and a brush disc 105 is rotatably connected in the disc cover 2, and the brush disc 105 is arranged horizontally.

[0039] Reference Figure 1 and Figure 2 The disc cover 2 is in an inverted U shape, and includes a top plate 201 and a side plate 202. The top plate 201 is horizontally arranged and fixedly connected to the bottom surface of the connecting column 104, and the brush disc 105 is rotatably connected to the lower surface of the top plate 201. The side plate 202 is vertically arranged, and the axis of the rear wheel 103 is perpendicular to the side plate 202. Two side plates 202 are arranged along the direction of the axis of the rear wheel 103, and the top plate 201 is integrally formed between the tops of the two side plates 202.

[0040] Reference Figure 1 and Figure 2 The two side panels 202 are provided with connecting components 3 on the opposite sides thereof, and each connecting component 3 is provided with a mounting component 4 on the side thereof facing away from the disk cover 2, and a scraping belt 5 that contacts the ground is connected to the mounting component 4. A height adaptive component 6 is connected between the connecting component 3 and the mounting component 4, and the mounting component 4 can descend along the height adaptive component 6 by its own weight.

[0041] When the floor scrubber is working, the front wheel 101 and the rear wheel 103 cooperate with each other to drive the floor scrubber forward, and at the same time, the brush plate 105 rotates, and the scraper belt 5 is pressed against the ground to scrape water. As the time of the workpiece increases, the contact time of the scraper belt 5 with the ground increases, causing the bottom surface of the scraper belt 5 to wear and a gap to form between the bottom of the scraper belt 5 and the ground. At this time, the mounting component 4 descends along the height adaptive component 6 by its own weight until the scraper belt 5 touches the ground again, ensuring the scraping effect and realizing the automatic adjustment of the height of the scraper belt 5.

[0042] Reference Figure 1 and Figure 2The connecting assembly 3 includes a connecting frame 301 and a rotating shaft 302.

The long straight side of the right-angled triangular plate 702 is attached to the top surface of the plug-in plate 701, and the short straight side is perpendicular to the plug-in plate 701. The height of the right-angled triangular plate 702 gradually decreases along the direction away from the inner wall of the side plate 202.

[0048] Reference Figure 4 In order to improve the smoothness of the plug board 701 when plugging, the upper edge and the lower edge of the plug board 701 facing the side of the inner vertical plate 3011 are chamfered.

[0049] When the brush plate 105 needs to be repaired or replaced, the operator presses the plug-in piece 7 downward, and when the highest point of the top of the right-angled triangle plate 702 is lower than the groove top wall of the locking opening 2022, the inner vertical plate 3011 is pulled away from the side plate 202, and the plug-in piece 7 is removed from the locking opening 2022, and the connecting frame 301 can be rotated, which is convenient for operation. After the maintenance is completed, the operator pushes the inner vertical plate 3011 in the direction toward the side plate 202, so that the plug-in piece 7 is inserted into the locking opening 2022, and the connecting frame 301 is locked.

[0050] Reference Figure 2 The top of the inner vertical plate 3011 is integrally formed with a horizontally arranged guide plate 3016, which is located on the side of the top surface of the inner vertical plate 3011 away from the rotating shaft 302. The guide plate 3016 provides a guide for the opening and closing of the connecting frame 301, further improving the stability when opening and closing the connecting frame 301.

[0051] Reference Figure 1 and Figure 2 The mounting assembly 4 includes an extension plate 401, a bearing plate 402 and a pressing plate 403. The bearing plate 402 and the pressing plate 403 are both arranged vertically and parallel to the side plate 202. The extension plate 401 is arranged horizontally and fixedly connected to the top surface of the bearing plate 402. The extension plate 401 is located above the top surface of the first inner horizontal plate 3012. The scraper belt 5 is clamped between the bearing plate 402 and the pressing plate 403.

[0052] Reference Figure 2 and Figure 3 The height adaptive component 6 includes a sliding rod 601 , and a positioning plate 4021 is fixedly connected to the side wall of the supporting plate 402 facing the side plate 202 . The positioning plate 4021 is horizontally arranged and located below the second inner horizontal plate 3014 .

[0053] Reference Figure 5The sliding rod 601 is vertically arranged, and the sliding rod 601 sequentially passes through the extension plate 401, the first inner transverse plate 3012, the second inner transverse plate 3014 and the positioning plate 4021.

[0055] Reference Figure 3 and Figure 6 The second rod 8022 is integrally formed at the top of the first rod 8021. The end of the second rod 8022 away from the first rod 8021 is arranged away from the sliding rod 601 and tilted upward. The end of the second rod 8022 away from the first rod 8021 is rotatably connected to the supporting plate 402 through a bolt.

[0056] Reference Figure 6 A mounting post 803 is fixedly connected to the side of the inner vertical plate 3011 facing the linkage rod 802. The mounting post 803 is arranged perpendicular to the inner vertical plate 3011 and is located between the sliding rod 601 and the linkage rod 802. The tension spring 801 is stretched between the mounting post 803 and the bottom of the first rod 8021. One end of the tension spring 801 is hung on the mounting post 803, and the other end is hung on the first rod 8021. The first rod 8021 is provided with a mounting hole for hanging the tension spring 801.

[0057] The tension spring 801 applies tension to the first rod 8021, and the first rod 8021 rotates clockwise under the action of the tension, and then links the second rod 8022 to rotate counterclockwise. The second rod 8022 applies downward pressure to the side of the supporting plate 402 away from the rotating shaft 302, so that the bottom surface of the scraper belt 5 is completely pressed against the ground, further improving the wiping effect.

[0058] Reference Figure 1 and Figure 5In order to further improve the wiping effect of the scraper belt 5, the bottom of the carrier plate 402 is bent in a direction away from the side plate 202, and the end of the carrier plate 402 close to the rear wheel 103 is bent toward the brush plate 105 and is arranged in an arc shape. The height of the bottom surface of the carrier plate 402 is higher than the height of the bottom surface of the scraper belt 5, and the bottom surface of the scraper belt 5 contacts the ground.

[0059] Reference Figure 1 and Figure 7 In order to facilitate the installation of the scraper belt 5, the pressing plate 403 is detachably connected to the bearing plate 402, and a clamping assembly 9 is connected between the pressing plate 403 and the bearing plate 402.

[0060] Reference Figure 7 and Figure 8 The clamping assembly 9 includes a lock buckle 901 and a locking block 902. The lock buckle 901 includes a lock hook 9021 and a fastening member 9022. The lock hook 9021 is fixedly connected to the side wall of the carrier plate 402 near the wide side of the front wheel 101 (refer to Figure 1 A mounting plate 9023 is fixedly connected to the side of the pressure plate 403 facing away from the scraper belt 5 , and a handle 9024 is rotatably connected to the mounting plate 9023 . The fastening member 9022 is buckled on the locking hook 9021 and is rotatably connected to the handle 9024 .

[0061] Reference Figure 7 and Figure 8 The locking block 902 is fixedly connected to one end of the carrier plate 402 away from the lock buckle 901, and the locking block 902 is located on the side of the carrier plate 402 facing the pressing plate 403. The pressing plate 403 is provided with a slot 4031 for the locking block 902 to be inserted. The end of the pressing plate 403 away from the lock buckle 901 is integrally formed with a stopper 4032. The stopper 4032 is fitted with the side wall at the wide side of the carrier plate 402, thereby improving the stability of the pressing of the pressing plate 403.

[0062] During installation, the operator fits the scraper belt 5 against the carrier plate 402, and then presses the pressure plate 403 onto the scraper belt 5. At the same time, the locking block 902 is inserted into the slot 4031. Finally, the operator turns the handle 9024 until the fastening piece 9022 is connected to the locking hook 9021, thereby achieving quick installation of the scraper belt 5.

[0063] Reference Figure 1 A positioning block 11 is fixedly connected to one side of the bearing plate 402 facing the scraper belt 5, and a plurality of positioning blocks 11 are arranged along the length direction of the bearing plate 402. The positioning blocks 11 penetrate the scraper belt 5 and the pressing plate 403. The positioning blocks 11 provide positioning for the installation of the scraper belt 5, thereby improving the stability of the installation of the scraper belt 5.

[0064] Reference Figure 1The top surface of the extension plate 401 is rotatably connected with an anti-collision wheel 11, which is located on the side of the upper plane of the extension plate 401 close to the front wheel 101. When the floor scrubber body 1 contacts the wall, the anti-collision wheel 11 has a buffering and guiding function for the floor scrubber body 1, thereby preventing the floor scrubber from directly colliding with the wall and protecting the floor scrubber.

[0065] The implementation principle of a floor scrubber that automatically adjusts the height of the scraper belt 5 in the embodiment of the present application is as follows: when working, the scraper belt 5 is pressed against the ground to scrape water. At this time, under the support of the scraper belt 5, a gap is left between the lower surface of the extension plate 401 and the top surface of the first inner horizontal plate 3012.

[0066] When the bottom surface of the scraper belt 5 is worn, a gap is generated between the scraper belt 5 and the ground, and the mounting assembly 4 moves vertically downward along the guide of the sliding rod 601 by its own gravity until the scraper belt 5 on this side touches the ground. At the same time, the tension spring 801 applies a pulling force to the first rod 8021, and the first rod 8021 rotates clockwise under the action of the pulling force, and then the second rod 8022 rotates counterclockwise in conjunction, and the second rod 8022 applies a downward pressure to the side of the mounting assembly 4 away from the rotating shaft 302, so that the bottom surface of the scraper belt 5 is completely pressed against the ground.

[0067] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
