Description

Technical Field

[0001] This invention relates to the field of floor grinding equipment technology, and more specifically, to a floor grinding robot. Background Technology

[0002] Floor grinding robots are automated devices that remove laitance from floor surfaces and grind uneven surfaces to a smooth finish. They are commonly used for flooring construction in facilities such as garages and factories. Floor grinding robots generate a large amount of dust during operation, and are usually equipped with vacuum cleaners. However, vacuum cleaner filters are prone to clogging during operation. If the dust on the filter is not cleaned promptly, it will reduce the filter's suction efficiency and may even damage the vacuum fan. Therefore, it is necessary to clean the dust from the filter surface regularly.

[0003] Currently, the filter element is usually vibrated by the operator manually pulling the lever on the bottom plate of the filter element back and forth to shake off the dust and remove the dust accumulated on the filter element, which results in low efficiency of the floor grinding robot. Summary of the Invention

[0004] The present invention aims to provide a floor grinding robot that can improve the efficiency of floor grinding robots.

[0005] The embodiments of the present invention can be implemented as follows: In a first aspect, the present invention provides a floor grinding robot, comprising: frame; A vacuum cleaner includes a housing, a filter element, a lever, and a drive element. The housing is disposed on a frame, and the filter element is disposed at the lower outlet of the housing. The filter element has a flexible sheet structure and has several protrusions at its bottom. The lever is disposed inside the housing and is opposite to the protrusions. The drive element is used to drive the lever to reciprocate horizontally, thereby driving the lever to abut against the protrusions in sequence. A dust bag is attached to the lower end of the housing for storing dust.

[0006] In an optional embodiment, the actuating element includes a sliding plate and an actuating block. The actuating block is disposed on the upper surface of the sliding plate, and the upper end of the actuating block that abuts against the filter element is an arc-shaped surface. The sliding plate is connected to the driving element, and the driving element is used to drive the sliding plate to reciprocate.

[0007] In an optional embodiment, the actuating block is a sphere; or, the actuating block is a hemisphere; or, the actuating block is a cylinder.

[0008] In an optional embodiment, the driving component includes a dust-vibrating motor, a driving rod, a guide shaft, and a connecting rod. The guide shaft is horizontally disposed in the housing and located below the filter element. The sliding plate is slidably sleeved on the guide shaft. The dust-vibrating motor is disposed in the housing. The driving rod is L-shaped. The vertical section of the driving rod is connected to the output shaft of the dust-vibrating motor, and the horizontal section of the driving rod is hinged to the connecting rod. The other end of the connecting rod is hinged to the toggle block. The dust-vibrating motor is used to drive the driving rod to rotate.

[0009] In an optional embodiment, two guide shafts are arranged in parallel on the frame, and the slide plate is simultaneously slidably sleeved on the two guide shafts.

[0010] In an optional embodiment, the floor grinding robot further includes a dust collection box and a rotating component. The dust collection box is located below the dust bag and has a working state and a storage state. In the working state, the dust collection box has its opening facing upward to accommodate and support the dust bag. In the storage state, the dust collection box has its opening facing the frame and is in contact with the frame. The dust collection box is rotatably mounted on the box body via the rotating component, which allows the dust collection box to flip and switch between the working state and the storage state.

[0011] In an optional embodiment, in the working state, at least a portion of the dust collection box abuts against the side of the frame to limit the position of the dust collection box.

[0012] In an optional embodiment, the rotating component includes a round shaft, an elastic part, and a fixing pin. The round shaft is horizontally disposed on the frame, and the dust collection box is rotatably disposed on the round shaft. The elastic part is connected between the frame and the dust collection box, and the elastic part causes the dust collection box to always have a tendency to rotate toward the working state. The fixing pin is used to pass through the dust collection box and the frame in the stored state, so as to place the dust collection box in the stored state on the frame.

[0013] In an optional embodiment, the floor grinding robot further includes a lever and a turntable bearing. The lever is hollow for threading cables and is L-shaped. The vertical section of the lever is rotatably mounted on the frame via the turntable bearing, and the horizontal section of the lever extends toward the rear of the floor grinding robot in the direction of travel.

[0014] In an optional embodiment, a limiting screw is provided at the bottom of the inner ring of the turntable bearing, and an arc-shaped groove is provided on the frame, with the limiting screw located in the arc-shaped groove to limit the rotation range of the lever.

[0015] The beneficial effects of the floor grinding robot provided in this embodiment of the invention include: The filter element has several protrusions at its lower end, along with a toggle and a drive. The drive drives the toggle to reciprocate, and the toggle then abuts against the protrusions at the lower end of the filter element in sequence. This causes the toggle to periodically strike the protrusions and vibrate the filter element within a small range, thus automatically shaking off the dust from the filter element. This eliminates the need for operators to manually vibrate the filter element for dust removal, and also eliminates the need to stop the machine for separate dust removal, thereby improving the efficiency of the floor grinding robot.

[0023] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0024] It should be noted that, where there is no conflict, the features in the embodiments of the present invention can be combined with each other.

[0025] Floor grinding robots are automated equipment used to remove laitance from the floor surface and grind uneven surfaces to a smooth finish. They are commonly used for floor construction in garages, factories, and other similar locations.

[0026] During floor grinding robot construction, a large amount of dust is generated. A vacuum cleaner is typically used to collect and store this dust. However, the vacuum cleaner's filter is prone to clogging during operation. If the dust on the filter is not cleaned promptly, it will reduce the filter's suction efficiency and may even damage the vacuum fan. Therefore, it is necessary to clean the dust surface of the filter regularly. Most vacuum cleaner filters on the market are cleaned by the operator manually pulling a lever on the filter's base plate to vibrate the filter and dislodge the dust. When the dust volume is large, the operator needs to pull the lever frequently, resulting in a heavy workload and reducing the automation level of the machine's operation.

[0027] Furthermore, floor grinding robots require a certain level of obstacle-crossing and hill-climbing capabilities, necessitating a large ground clearance at the robot's tail for easy relocation. When transporting the robot by truck, its overall height needs to be minimized to fit into the truck bed. The size of the vacuum cleaner mounted at the robot's tail significantly impacts the overall height. Currently, vacuum cleaners mounted behind grinding machines on the market are either positioned very high to ensure sufficient clearance between the vacuum cleaner's outlet and the dust collection box for changing bagged dust, making loading such machines into truck beds extremely inconvenient; or, in an attempt to reduce the overall height, the vacuum cleaner is positioned relatively low, but this compresses the clearance between the vacuum cleaner's outlet and the dust collection box, making bagged dust changing inconvenient, reducing manual efficiency, and affecting the robot's maneuverability, with the dust collection box easily bumping into the ground when climbing slopes or over obstacles.

[0028] Furthermore, existing floor grinding machines typically have their power cable tied to a handle at the rear of the machine, requiring manual pushing during operation. When the machine turns or rotates, manual assistance is applied to pull the power cable to prevent damage. However, floor grinding robots, which automatically move, turn, and rotate along a planned path while dragging their power cable, require the cable to be moved to the side of the robot to prevent damage and to avoid running over it. Without human assistance or a dedicated mechanism, the power cable cannot be automatically moved to the side of the robot, hindering the operation.

[0029] To address the aforementioned technical problems, this invention provides a floor grinding robot. The overall structure, working principle, and technical effects of the floor grinding robot provided by this invention are described in detail below with reference to embodiments and accompanying drawings.

[0030] Please refer to Figures 1-8The floor grinding robot provided by this invention includes a frame 100, a vacuum cleaner 200, and a dust bag 300. The frame 100 serves as the main frame of the floor grinding robot, providing a mounting carrier for it. The vacuum cleaner 200 includes a housing 210, a filter element 220, an actuating component 230, and a driving component 240. The housing 210 is mounted on the frame 100, and the filter element 220 is disposed within the housing 210 and located at the lower outlet of the housing 210. Specifically, the filter element 220 has a flexible sheet structure, and the bottom of the filter element 220 has several protrusions 221, making the bottom of the filter element 220 serrated. The actuating element 230 is disposed inside the housing 210 and opposite to the protrusion 221. The driving element 240 is used to drive the actuating element 230 to move horizontally, thereby driving the actuating element 230 to abut against a number of protrusions 221 in sequence. As the actuating element 230 moves, it abuts against a number of protrusions 221 in sequence, thereby impacting a number of protrusions 221 in sequence, causing the flexible filter element 220 to vibrate back and forth within a small range, thereby automatically shaking off the dust on the filter element 220.

[0031] By setting several protrusions at the lower end of the filter element 220, and setting a toggle member 230 and a drive member 240, the drive member 240 drives the toggle member 230 to reciprocate. The toggle member 230 then abuts against the several protrusions at the lower end of the filter element 220 in sequence, so that the toggle member 230 periodically impacts the protrusions 221 and causes the filter element 220 to vibrate within a small range. This achieves the effect of automatically shaking off the dust on the filter element 220, eliminating the need for operators to manually vibrate the filter element 220 for dust removal, and eliminating the need to stop the machine for separate dust removal operations, thus improving the efficiency of the floor grinding robot.

[0032] Please refer to Figure 2 and Figure 3 In some optional embodiments, the actuating member 230 includes a sliding plate 231 and an actuating block 232. The sliding plate 231 is located below the filter element 220, and the actuating block 232 is disposed on the upper surface of the sliding plate 231. The upper end of the actuating block 232 that abuts against the filter element 220 is an arc-shaped surface. The actuating block 232 is connected to the sliding plate 231, and the driving member 240 is used to drive the sliding plate 231 to reciprocate in the horizontal direction. Further, the actuating block 232 may be a sphere; or, in some optional embodiments, the actuating block 232 may also be a hemisphere; or, in other optional embodiments, the actuating block 232 may also be a cylinder, which is horizontally disposed on the sliding plate 231, and the axis of the cylinder is perpendicular to the line connecting the plurality of protrusions 221. In order to improve the vibration effect of the actuating block 232 on the filter element 220, in this embodiment, the actuating block 232 is provided at both ends of the slide plate 231, so that the actuating member 230 can simultaneously support the filter elements 220 on both sides of the housing 210, thereby driving the filter elements 220 on both sides to vibrate and improving the dust removal efficiency of the filter element 220.

[0033] By setting the upper end of the actuating block 232 to an arc shape, during the reciprocating motion of the actuating block 232, the protrusion 221 contacts and slides along the arc surface of the actuating block 232, resulting in a smooth movement. This causes the filter element 220 to vibrate within a small range while preventing excessive vibration and damage to the filter element 220. It is understood that the size of the actuating block 232 matches the protrusion 221 so that the actuating block 232 only contacts the protrusion 221 and not the filter element 220 body, thus preventing the actuating block 232 from directly impacting the filter element 220 and causing damage.

[0034] Please refer to Figure 2 and Figure 3 In some optional embodiments, the drive component 240 includes a dust-vibrating motor 241, a drive rod 242, a guide shaft 243, and a connecting rod 244. The guide shaft 243 is horizontally disposed on the housing 210 and located below the filter element 220. The slide plate 231 is slidably sleeved on the guide shaft 243. The dust-vibrating motor 241 is disposed inside the housing 210. The drive rod 242 is L-shaped. The vertical section of the drive rod 242 is detachably connected to the output shaft of the dust-vibrating motor 241 through a clamping block. The end of the horizontal section of the drive rod 242 is hinged to the connecting rod 244. The other end of the connecting rod 244 is hinged to the toggle block 232. The dust-vibrating motor 241 is used to drive the drive rod 242 to rotate. Furthermore, the slide plate 231 is hollow, and the drive rod 242 passes through the slide plate 231, so that the drive rod 242 and the connecting rod 244 form a crank rocker structure. When the drive rod 242 is driven to rotate, it drives the slide plate 231 to reciprocate through the connecting rod 244, so that the actuating block 232 reciprocates to move the filter element 220.

[0035] When the filter 220 of the vacuum cleaner 200 needs dust removal, the main shaft of the dust-removing motor 241 rotates, and the drive plate rotates synchronously with the main shaft of the dust-removing motor 241, driving the sliding plate 231 to slide back and forth along the guide shaft 243. The actuating block 232, fixed on the sliding plate 231, slides back and forth with the sliding plate 231. The top arc surface of the actuating block 232 contacts the protrusion 221 at the bottom of the filter 220. Under the action of the ball, the bottom of the filter 220 repeatedly opens and closes, thereby shaking off the dust on the surface of the filter 220. The entire process is powered by the dust-removing motor 241, and the machine's automated dust removal can be achieved by controlling the dust-removing motor 241.

[0036] Please refer to Figure 3 In some optional embodiments, to improve the stability of the slide plate 231 during movement, two guide shafts 243 are arranged in parallel on the frame 100, and the slide plate 231 is simultaneously slidably fitted onto the two guide shafts 243. By having the two guide shafts 243 simultaneously support and guide the slide plate 231, the stability of the slide plate 231's movement is improved.

[0037] Please refer to Figures 4-6In some alternative embodiments, the floor grinding robot also includes a dust collection box 400 and a rotating component 500. The dust collection box 400 is located below the dust bag 300 and has a working state and a storage state. Figure 4 In the working state, the dust collection box 400 has its opening facing upwards to accommodate and support the dust bag 300; combined with Figure 6 When the dust collection box 400 is in the storage state, its opening faces the frame 100 and is in contact with the frame 100. The dust collection box 400 is rotatably mounted on the box body 210 via a rotating component 500, which allows the dust collection box 400 to flip and switch between the working state and the storage state.

[0038] Furthermore, in this embodiment, please refer to Figure 4 and Figure 5 When the dust collection box 400 is in operation, at least part of its side abuts against the side of the frame 100 to limit and fix the dust collection box 400 in operation, so that the dust collection box 400 can only be flipped towards the storage position in operation.

[0039] Please refer to Figure 4 and Figure 5 In some alternative embodiments, the rotating component 500 includes a round shaft 510, an elastic portion 520, and a fixing pin 530. The round shaft 510 is horizontally disposed on the frame 100, and the top of one side of the dust collection box 400 is rotatably disposed on the round shaft 510. The elastic portion 520 connects the frame 100 and the dust collection box 400, and the elastic portion 520 ensures that the dust collection box 400 always tends to rotate towards the working state. In this embodiment, the elastic portion 520 includes a nitrogen spring. In other alternative embodiments, the elastic portion 520 can also be a spring or other structure capable of applying elastic force to the dust collection box 400. When the dust collection box 400 is flipped to the storage state, the fixing pin 530 can pass through both the dust collection box 400 and the frame 100 simultaneously, thereby fixing the dust collection box 400 to the frame 100 in the storage state.

[0040] Specifically, in this embodiment, the fixing pin 530 is a knob quick-release pin, which is fixed to the rear of the frame 100. Rotating the knob quick-release pin allows the pin inside to extend and retract flexibly. Meanwhile, the dust collection box 400 is provided with a round hole that matches the pin inside the knob quick-release pin. Furthermore, to facilitate the flipping of the dust collection box 400, handles for operators to hold are provided on both sides of the dust collection box 400, making it easier for operators to flip the dust collection box 400.

[0041] By rotating the dust collector 400 onto the frame 100, when the floor grinding robot needs sufficient space to bag dust during operation, the dust collector 400 is tilted down, rotating around the circular shaft 510 to its working state. The dust collector 400 is then limited by the frame 100, creating a significant distance between the bottom of the dust collector 400 and the dust outlet of the housing 210, facilitating bag replacement and dust filling. Simultaneously, the bottom of the dust collector 400 maintains a small distance from the floor surface. Since the floor surface is relatively flat during operation, the bottom of the dust collector 400 will not hit the ground, ensuring normal machine operation. The elastic part 520 continuously applies a downward force to the dust collector 400 during operation, keeping it stable and preventing it from shaking and affecting the work. When the floor grinding robot finishes its work and needs to be moved to another location, first unload the dust bag 300, then flip the dust collection box 400 up to its storage position and lock it in place using the fixing pin 530. At this time, the lowest surface of the dust collection box 400 can maintain a large distance from the floor surface, improving the robot's mobility and preventing it from hitting the ground when going uphill or over obstacles.

[0042] Please refer to Figure 7 and Figure 8 In some optional embodiments, the floor grinding robot also includes a lever 600 and a turntable bearing 610. The lever 600 is hollow for cable routing. The lever 600 is L-shaped, with its vertical section rotatably mounted on the frame 100 via the turntable bearing 610. The horizontal section of the lever 600 extends towards the rear of the floor grinding robot in the direction of travel. Furthermore, to facilitate cable routing, corrugated pipe joints are provided at both ends of the lever 600, and the corners of the lever 600 are rounded. After exiting the electrical box, the power cable passes sequentially through the corrugated pipe joint, the interior of the lever 600, and another corrugated pipe joint, extending to the outside of the lever 600 and connecting to an external power connector for fixation.

[0043] Please refer to Figure 8 Furthermore, in some optional embodiments, the outer ring of the turntable bearing 610 is fixed on the frame 100, the inner ring of the turntable bearing 610 is fixed on the lever 600, a limit screw 120 is fixed at the bottom of the inner ring of the turntable bearing 610, an arc groove 110 is provided at the mounting position of the turntable bearing 610 on the frame 100, and the limit screw 120 is located in the arc groove 110 of the frame 100 to limit the limit screw 120.

[0044] One end of the power cable is fixed to an external power connector. During grinding operations, the robot moves in a straight line, and the power cable exerts a positive pull on the lever 600. At this time, the lever 600 drags the power cable along with the robot in a straight line. When the robot turns or rotates, the power cable exerts an oblique pull on the lever 600. Because the lever 600 is fixed to the inner ring of the turntable bearing 610, and the outer ring of the turntable bearing 610 is fixed to the main frame 100, and the resistance of the inner ring of the turntable bearing 610 rotating around the outer ring is small, the lever 600 rotates together with the inner ring of the turntable bearing 610 in the opposite direction of the robot's turn under the oblique pull of the power cable. This causes the power cable inside the lever 600 to twist synchronously with the lever 600. This prevents excessive bending of the power cable and improves its lifespan. When the robot continues to turn or turn around, the limiting screw 120 on the lever 600 rotates to the limit position of the limiting groove and is limited. The lever 600 and the main frame 100 no longer move relative to each other. Because the lever 600 extends outside the robot's main frame 100, when the robot continues to turn, the lever 600 can move the power cable aside, preventing the robot wheels from running over the power cable, thus completing the cable-moving action. Since the power cable is fixed in the inner hole of the lever 600, and extends a certain length from the turntable bearing 610 before connecting to the electrical box, this length increases the flexibility of the power cable, resulting in less damage when the power cable twists within the limited rotation range of the lever 600. Secondly, because the rotational resistance of the turntable bearing 610 is small, the resistance of the lever 600 during rotation is also small, requiring less power and making it suitable for applications in floor grinding robots and other automated equipment.

[0045] In summary, the implementation principle of the floor grinding robot provided by the present invention is as follows: several protrusions are provided at the lower end of the filter element 220, and a toggle member 230 and a drive member 240 are provided. The drive member 240 drives the toggle member 230 to reciprocate. The toggle member 230 then abuts against the several protrusions at the lower end of the filter element 220 in sequence, so that the toggle member 230 periodically impacts the protrusions 221 and causes the filter element 220 to vibrate within a small range, thereby achieving the effect of automatically shaking off the dust on the filter element 220. There is no need for the operator to manually vibrate the filter element 220 for dust removal, thus improving the efficiency of the floor grinding robot. Dust removal operations can be performed without stopping the floor grinding robot, reducing downtime and improving efficiency.

Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
