Description

Technical Field

[0001] This utility model relates to the field of floor scrubbing equipment technology, and in particular to an improved structure for adjusting the water squeegee. Background Technology

[0002] A floor scrubber is a cleaning machine suitable for cleaning hard floors while simultaneously drying wastewater and removing it from the site. It boasts advantages such as environmental friendliness, energy efficiency, and high performance. Floor scrubbers are widely used in various sectors of society, especially in places with large hard floors such as train stations, docks, airports, workshops, warehouses, schools, hospitals, restaurants, and shopping malls.

[0003] A floor scrubber is a cleaning machine used to clean hard floors while simultaneously vacuuming up wastewater and removing it from the site. It offers advantages such as environmental friendliness, energy efficiency, and high performance. Floor scrubbers typically consist of a brush and a squeegee mounted on a frame. The brush cleans the floor, and the squeegee removes the wastewater.

[0004] Floor scrubbers clean wastewater from the floor using a squeegee fixed at the bottom. However, the squeegee's constant contact with the floor and the resulting friction can shorten its lifespan. While some squeegee designs have been improved, most remain quite complex. Utility Model Content

[0005] The present invention aims to provide an improved structure for adjusting the squeegee of a ride-on floor scrubber, which extends the service life of the squeegee and makes the adjustment operation simple.

[0006] To solve the above problems, this utility model provides an improved structure for adjusting the water squeegee of a ride-on floor scrubber, including a water squeegee and a water squeegee fixing plate. The feature is that it also includes a movable water squeegee plate. The water squeegee is fixedly connected to the water squeegee fixing plate via a water squeegee fixing screw. The movable water squeegee plate is movably connected to the upper surface of the water squeegee fixing plate via a water squeegee rotation mechanism. A water squeegee lifting mechanism is connected to the tail end of the movable water squeegee plate.

[0007] The improved structure for adjusting the water squeegee of a ride-on floor scrubber is characterized in that: the water squeegee rotation mechanism includes an adjusting screw, a fixing screw, an adjusting screw hole provided on the fixing screw, two fixed plate movable connecting blocks provided on the upper end of the water squeegee fixed plate, a movable hole provided on the water squeegee movable plate, a movable plate movable connecting block, and a U-shaped bracket provided on its edge.

[0008] The fixing screw is movably installed on the two bracket walls at the open end of the U-shaped bracket, and the adjusting screw is threaded through the adjusting screw hole and fixedly connected to the water scraper fixing plate at its tail end by a nut.

[0009] The upper front surface of the movable blade of the water scraper is provided with movable plate connecting blocks on both sides, which are movably connected to the movable plate connecting blocks of the fixed plate through screws, so that the movable blade of the water scraper is movably connected to the fixed plate of the water scraper. Adjusting the adjusting screw can make the fixed plate of the water scraper drive the water scraper to rotate longitudinally.

[0010] The improved structure for adjusting the water squeegee of a ride-on floor scrubber is characterized in that: a fixing screw hole is provided on the water squeegee fixing plate, the adjusting screw is threaded through the adjusting screw hole, and its tail end passes through the fixing screw hole and is fixed to the water squeegee fixing plate by a nut.

[0011] The improved structure for adjusting the water squeegee of a ride-on floor scrubber is characterized in that: the water squeegee lifting mechanism includes a lifting motor, a lifting bridge, and a lifting plate; the lifting plate is movably installed on the upper surface of the movable plate of the water squeegee, and the tail of the lifting plate is fixedly connected to the lifting bridge; the other end of the lifting bridge is movably connected to a gantry bracket via a mounting bracket; the lifting motor is installed above the lifting plate via the gantry bracket; the lifting and retracting end of the lifting motor is connected to a lifting block on the lifting plate via a spring; when the lifting motor performs lifting and retracting movements, the water squeegee moves up and down via the lifting plate.

[0012] The improved adjustable structure for a ride-on floor scrubber squeegee is characterized in that: the lifting mechanism is further provided with a turning buffer structure, which includes an arc-shaped waist hole at the front of the lifting plate, a turning buffer screw, a buffer rotating screw, a second buffer rotating hole at the rear of the movable squeegee plate, a turning buffer screw fixing hole in the middle, and a first buffer rotating hole at the rear of the lifting plate; one end of the turning buffer screw is fixed to the turning buffer screw fixing hole, and the other end is movably installed in the arc-shaped waist hole, allowing the lifting plate and the movable squeegee plate to be movably connected left and right; the first buffer rotating hole and the second buffer rotating hole are movably connected by the buffer rotating screw.

[0014] The improved structure for adjusting the water squeegee of a ride-on floor scrubber is characterized in that the water squeegee is also equipped with a wastewater suction port.

[0015] The improved structure for adjusting the water squeegee of a ride-on floor scrubber is characterized in that: each end of the water squeegee fixing plate is provided with a corresponding "L" fixing hole, and the water squeegee fixing screw fixes the water squeegee to the water squeegee fixing plate through the "L" fixing hole.

[0016] With the above structure, the squeegee mounting plate can be rotated longitudinally simply by adjusting the adjusting screw. Under the operator's visual supervision, the contact angle between the squeegee and the floor can be adjusted to a suitable angle, reducing squeegee wear. The turning buffer structure, composed of an arc-shaped waist hole, a buffer rotating screw, and a turning buffer screw, provides a buffer when the floor scrubber turns, reducing wear caused by sharp turns. Simultaneously, the squeegee lifting mechanism raises the squeegee away from the ground after the floor scrubber finishes its work, preventing squeegee wear. This triple protection extends the squeegee's service life. Furthermore, the turning buffer structure and the squeegee rotating mechanism are simple in design, easy to operate and implement.

[0020] The following detailed description, in conjunction with the accompanying drawings and specific embodiments, further illustrates an improved structure for adjusting the water scraper of a ride-on floor scrubber according to this utility model.

[0021] like Figure 1 , Figure 2 As shown, an improved structure for adjusting the squeegee of a ride-on floor scrubber includes a squeegee 1, a squeegee fixing plate 2, and a squeegee movable plate 3. The squeegee 1 is fixedly connected to the squeegee fixing plate 2 via a squeegee fixing screw 101. The squeegee movable plate 3 is movably connected to the upper surface of the squeegee fixing plate 2 via a squeegee rotation mechanism. A squeegee lifting mechanism is connected to the tail end of the squeegee movable plate 3.

[0022] The water wiper rotation mechanism includes an adjusting screw 402, a fixing screw 401, an adjusting screw hole 403 on the fixing screw 401, two movable connecting blocks 201 on the upper end of the water wiper fixed plate 2, a movable hole 301 on the movable water wiper plate 3, a movable connecting block 303 on the movable plate, and a U-shaped bracket 302 on its edge. The fixing screw 401 is movably installed on the two bracket walls at the open end of the U-shaped bracket 302. The adjusting screw 402 is threaded through the adjusting screw hole 403 and is fixedly connected to the water wiper fixed plate 2 at its tail end by a nut. The movable connecting block 303 on the movable plate is movably connected to the movable connecting block 201 on the fixed plate by a screw, so that the movable water wiper plate 3 is movably connected to the water wiper fixed plate 2 (i.e., the water wiper fixed plate 2 rotates up and down around the connection between the movable connecting block 303 on the movable plate and the movable connecting block 201 on the fixed plate). Figure 3Adjusting the adjusting screw 402 shortens the distance between the fixing screw 401 and the wiper fixing plate 2, causing the wiper fixing plate 2 to rotate upwards; conversely, adjusting the adjusting screw 402 lengthens the distance between the fixing screw 401 and the wiper fixing plate 2, causing the wiper fixing plate 2 to rotate downwards. By adjusting the adjusting screw 402, the wiper fixing plate 2 can drive the wiper 1 to rotate longitudinally.

[0023] The water scraper fixing plate 2 is provided with a fixing screw hole 202. The adjusting screw 402 is threaded through the adjusting screw hole 403, and its tail end passes through the fixing screw hole 202 and is fixed to the water scraper fixing plate 2 by a nut.

[0024] The water scraper lifting mechanism includes a lifting motor 501, a lifting bridge 502, and a lifting plate 503. The lifting plate 503 is movably mounted on the upper surface of the movable water scraper plate 3, and its tail end is fixedly connected to the lifting bridge 502. The other end of the lifting bridge 502 is movably connected to a gantry bracket 504 via a mounting bracket. The lifting motor 501 is mounted above the lifting plate 503 via the gantry bracket 504. The lifting and retracting end of the lifting motor 501 is connected to the lifting block 505 on the lifting plate 503 via a spring 506. When the lifting motor 501 moves up and down, the lifting plate 503, connected to the lifting and retracting end of the lifting motor 501 via the spring 506, drives the water scraper 1 to move up and down. When the lifting and retracting end of the lifting motor 501 retracts, the water scraper 1 moves away from the ground; when the lifting and retracting end of the lifting motor 501 extends, the water scraper 1 contacts the ground.

[0025] The lifting mechanism is also equipped with a turning buffer structure for the floor scrubber when turning. The turning buffer structure includes an arc-shaped waist hole 601 at the front of the lifting plate 503, a turning buffer screw 602, a buffer rotating screw 603, a second buffer rotating hole 304 at the tail of the squeegee movable plate 3, a turning buffer screw fixing hole 305 in the middle, and a first buffer rotating hole 507 at the tail of the lifting plate 503. One end of the turning buffer screw 602 is fixed to the turning buffer screw fixing hole 305, and the other end is movably installed in the arc-shaped waist hole 601, movably connecting the lifting plate 503 and the squeegee movable plate 3. The first buffer rotating hole 507 and the second buffer rotating hole 304 are movably connected by the buffer rotating screw 603. When the floor scrubber turns, under the combined action of the buffer rotating screw 603 and the turning buffer screw 602, the squeegee 1 receives a buffer during the turn, reducing wear caused by sharp turns.

[0026] An adjusting handwheel 7 is fixedly installed on the upper end of the adjusting screw 402. The outer wall of the adjusting handwheel 7 is provided with anti-slip texture for easy operation.

[0027] The squeegee 1 is also equipped with a wastewater suction port 102. During the cleaning process, the floor scrubber collects wastewater from the ground into the wastewater tank through the wastewater suction port 102.

[0028] The water scraper fixing plate 2 has corresponding "L" fixing holes at both ends. The water scraper fixing screw 101 fixes the water scraper 1 to the water scraper fixing plate 2 through the "L" fixing holes.

[0029] When the floor scrubber is working, first start the lifting mechanism. The lifting motor 501 extends, slowly lowering the squeegee 1. When the lifting motor 501 stops moving, the operator manually adjusts the adjusting screw 402 to rotate the squeegee down, maintaining an angle between 20° and 10° with the ground, ensuring that the squeegee 1 is in contact with the ground on the same line. This allows the squeegee 1 to properly collect wastewater from the floor into the wastewater tank while reducing friction between the squeegee 1 and the floor. The turning buffer structure provides a buffer when the floor scrubber turns, reducing wear caused by sharp turns.

[0030] When the floor scrubber is in operation, first manually adjust the adjusting screw 402 in the reverse direction to adjust the squeegee 1 to be parallel to the ground, and then start the lifting mechanism to lift the squeegee 1.

[0031] This prevents the squeegee 1 from rubbing against the floor when the floor scrubber is used after finishing work, thus extending the service life of the squeegee 1.

[0032] The preferred embodiments or specific implementations of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above-described embodiments and implementations. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the concept of the present invention.
