Description

Technical Field

[0001] This invention relates to the field of troweling machines, and in particular to a ride-on troweling machine with slurry filling function. Background Technology

[0002] A floor trowel is a machine used to smooth floor surfaces made of concrete, cement, mortar, or other suitable mineral materials. It can perform both rough and fine finishing on concrete surfaces, resulting in smoother and flatter surfaces compared to those finished manually. This significantly improves the density and wear resistance of the concrete surface. Floor trowels are widely used for leveling, smoothing, and finishing concrete or other mineral material surfaces in high-standard factories, warehouses, parking lots, plazas, airports, and framed buildings.

[0003] However, the existing troweling machines have trowels mounted on trowels. When the troweling machine needs to finish the surface, the trowels must be manually removed. This requires lifting or hoisting the troweling machine to remove and install the trowels, which is not only time-consuming and labor-intensive but also poses a risk of injury to workers. Furthermore, when encountering uneven or pitted surfaces, operators typically use handheld shovels or shovels to fill the pits and pits with material and manually swing the shovel to level the area. This process is not only time-consuming and labor-intensive but also ineffective. When the troweling machine is used to smooth the surface, any protruding parts are stirred up and fall onto the trowels. The filling effect needs further optimization.

[0004] Therefore, we provide a ride-on trowel with slurry filling function to solve the technical problems existing in the prior art. Summary of the Invention

[0005] To address the technical problems existing in the prior art, the present invention provides a ride-on power trowel with slurry filling function, including a frame, and an engine, main water tank, seat, oil tank and control lever mounted on the frame. The frame is also connected to a power trowel assembly and a slurry filling assembly, and an adjusting roller is connected between the power trowel assembly and the filling assembly. The adjusting roller is rotatably connected to the frame.

[0006] The smoothing assembly includes a transmission part rotatably mounted on a frame. The transmission part has multiple connecting rods arranged in a circular array. Each connecting rod is connected to a smear. An internal gear located inside the transmission part is connected to each connecting rod. An active adjusting wheel and a driven adjusting wheel located inside the transmission part are coaxially mounted on the adjusting roller. An adjusting motor that is pulverized and driven by the active adjusting wheel is connected to the transmission part. The transmission part is connected to a smearing disc, and the smearing disc is provided with mating holes for accommodating the smear.

[0007] The smoothing assembly drives the active adjusting wheel and the adjusting roller through the worm gear on the adjusting motor, so that the driven adjusting wheel on the adjusting roller drives the internal gear to rotate, so that the connecting rod drives the squeegee to flip in the mating hole of the squeegee, so that a first opening or a second opening is formed between the squeegee and the squeegee.

[0008] The controller has three operating modes for the smoothing component: smoothing disc mode, smoothing sheet mode, and filling mode.

[0009] The smoothing component is initially in the smoothing disc mode, that is, the smoothing disc is set parallel to the smoothing disc, the smoothing disc does not flip in the mating hole, the bottom of the smoothing disc is basically flush with the bottom of the smoothing disc, and both are in contact with the base surface to be smoothed, so that the two cooperate to form a complete smoothing disc mode, thereby performing a smoothing operation on the base surface to be smoothed.

[0010] When the operator triggers the filling mode through the controller, the controller controls the adjusting motor to rotate forward, causing the worm gear to drive the adjusting roller on the worm wheel to rotate forward. The forward rotation of the adjusting roller causes the connecting rod to rotate in reverse, and the slurry plate flips in the mating hole. At the same time, the external gear on the connecting rod, in conjunction with the spur gear, synchronously drives the limiting block away from the bottom end of the transmission part, so that one end of the slurry plate is higher than the slurry plate, and a first opening is formed between the two. The other end of the slurry plate is almost flush with the slurry plate. The reducer is controlled to drive the transmission part to rotate in reverse, and the slurry pump is controlled to deliver slurry into the filling pipe. The slurry in the filling pipe is then sprayed out through the nozzle to the first opening. At this time, the slurry plate does not contact the base surface to be smoothed, while the slurry plate contacts the base surface to be smoothed. The sprayed slurry is guided by the inclined slurry plate to the lower end of the slurry plate and then smoothed out, thereby achieving the effect of flexibly and timely filling the areas on the base surface that need to be replenished with slurry.

[0011] When the operator triggers the smearing mode via the controller, the controller reverses the adjustment motor, causing the worm gear to drive the adjustment roller on the worm wheel to reverse as well. The reverse rotation of the adjustment roller causes the connecting rod to rotate forward, causing the smear to flip within the mating hole. Simultaneously, the external gear on the connecting rod engages with the spur gear, synchronously driving the limit block closer to the bottom of the transmission unit. This results in one end of the smear being lower than the smear disc, and the other end being higher than the smear disc, forming a second opening between them. The smear disc does not contact the surface to be smoothed; only the smear releases the surface from smoothing. By controlling the reducer to drive the transmission unit to rotate forward, the smear in the smoothing assembly performs the smoothing operation on the surface to be smoothed. This is the smoothing mode of the present invention. The versatility allows the trowel to flexibly switch between different working modes of the trowel pad and the trowel disc, eliminating the need for operators to manually disassemble and reassemble the trowel disc to switch between the two working modes. This saves operators time on disassembling and reassembling the trowel disc and reduces downtime for the trowel, bringing convenience to operators and further improving the working efficiency of the trowel. Moreover, the trowel is replenished by the filling tube in the filling component in conjunction with the nozzle to the first opening formed on the trowel disc. The replenished trowel is guided to the bottom of the trowel disc for rapid smoothing, with high filling efficiency and no spillage on the trowel disc. It also eliminates the need for operators to manually fill with a hand shovel, saving labor costs.

[0012] The slurry filling assembly includes a slurry tank and a slurry pump mounted on a frame. The slurry tank is connected to a delivery pipe via the slurry pump. The delivery pipe is connected to a connecting part, which is rotatably connected to one end of an adjusting roller. The other end of the adjusting roller is connected to a connecting cylinder inside a transmission unit. The connecting cylinder is connected to a filling pipe mounted on a trowel. The adjusting roller has a through hole communicating with the filling pipe and the delivery pipe. The slurry in the slurry tank of the slurry filling assembly flows through the through hole into the connecting cylinder. The slurry in the connecting cylinder is sprayed out through the nozzle of the filling pipe into a first opening. The sprayed slurry is guided by a trowel to the bottom of the trowel and then filled and smoothed.

[0013] Furthermore, the smoothing assembly also includes a reducer mounted on the frame, the reducer being connected to the engine via a transmission, the engine driving the transmission unit through the reducer, one end of the adjusting roller being rotatably connected to the frame and extending to the upper end of the frame, and connecting frames being provided on both the main water tank and the oil tank, the connecting frames being inserted into the T-slots, the connecting frames being connected to the conveying pipe, and the connecting frames being rotatably connected to the adjusting roller.

[0014] Furthermore, the smoothing component also includes a plurality of limiting blocks arranged in a circumferential array on the smoothing plate. The limiting blocks are provided with straight teeth and limiting grooves. The outer circumferential array of the transmission part has a plurality of connecting blocks. The transmission part is slidably inserted into the limiting groove of the limiting block through the connecting blocks.

[0015] Furthermore, an external gear located outside the transmission part is movably disposed on the connecting rod, and a clearance groove is provided on the connecting rod. The external gear is slidably connected to the connecting rod through the clearance groove, and the connecting rod is meshed with the spur tooth part on the limiting block through the external gear.

[0016] Furthermore, the shovel is also provided with a clearance hole corresponding to the bottom of the transmission part. When the connecting rod rotates, the external gear drives the limiting block on the spur gear part and the shovel to move along the axial direction of the transmission part.

[0017] Furthermore, the slurry filling assembly also includes a secondary water tank disposed on the slurry tank, the secondary water tank being connected to a water supply pump, the water supply pump being connected to the delivery pipe via a first check valve, and the slurry supply pump being connected to the delivery pipe via a second check valve.

[0018] Furthermore, the transmission part has multiple connecting holes arranged in a circumferential array, and one end of the connecting rod passes through the connecting hole and is placed inside the transmission part.

[0019] Furthermore, the nozzle of the filling tube is located at the side end of the mating hole, and there is a clearance area between the filling tube and the smear plate.

[0020] Furthermore, the output end of the regulating motor is connected to a worm gear, the active regulating wheel is configured as a worm wheel that cooperates with the worm gear, a storage battery is installed inside the transmission part, and the regulating motor is connected to the storage battery.

[0021] Furthermore, a controller is connected to the seat, and the engine, slurry pump, water pump, reducer, and regulating motor are signal-connected to the controller.

[0022] Compared with the prior art, the ride-on power trowel with slurry filling function provided by this invention has the following advantages:

[0023] 1. The smoothing component of this invention has three operating modes: smoothing disc mode, smoothing pad mode, and filling mode. These multiple operating modes are controlled by adjusting the connecting rod of the adjusting roller via a control motor. This allows the smoothing pad to rotate within the mating hole of the smoothing disc, enabling the smoothing component to flexibly switch between smoothing, filling, and smoothing modes. Compared to traditional smoothing machines that require machine downtime and manual disassembly and assembly of the smoothing disc, this invention eliminates the manual disassembly and assembly steps for switching between smoothing and smoothing modes, providing convenience for operators, saving downtime, and further improving the working efficiency of the smoothing machine.

[0024] 2. The smoothing component of the present invention is initially in the smoothing disc mode, that is, the smoothing disc is set parallel to the smoothing disc, the smoothing disc does not flip in the mating hole, the bottom of the smoothing disc is basically flush with the bottom of the smoothing disc, and both are in contact with the base surface to be smoothed, so that the two cooperate to form a complete smoothing disc mode, thereby performing a smoothing operation on the base surface to be smoothed.

[0025] 3. When the operator triggers the filling mode via the controller, the controller controls the adjusting motor to rotate forward, causing the worm gear to drive the adjusting roller on the worm wheel to rotate forward. The forward rotation of the adjusting roller causes the connecting rod to rotate in reverse, and the slurry plate flips within the mating hole. Simultaneously, the external gear on the connecting rod engages with the spur gear to synchronously drive the limiting block away from the bottom end of the transmission unit, thereby causing one end of the slurry plate to be higher than the slurry plate, forming the first opening between them. The other end of the slurry plate is nearly flush with the slurry plate. The reducer is then controlled to drive the transmission unit in reverse, and the slurry pump is controlled to deliver slurry into the filling pipe. The slurry in the filling pipe then... The grout is sprayed through the nozzle into the first opening. At this time, the smear does not contact the base surface to be smoothed, while the smear plate contacts the base surface. The sprayed grout is guided by the inclined smear to the lower end of the smear plate and then smoothed. This achieves the effect of flexibly and promptly filling the areas on the base surface that need grout replenishment. Compared with the traditional method of manually visually inspecting and then filling with tools, this structure is flexible, timely, and prevents grout above the base surface from being stirred up to the top of the smear plate, thus ensuring that the filled area is effectively filled.

[0026] 4. When the operator triggers the smear mode via the controller, the controller controls the adjusting motor to reverse, causing the worm gear to drive the adjusting roller on the worm wheel to reverse. The reverse rotation of the adjusting roller causes the connecting rod to rotate forward, and the smear flips within the mating hole. Simultaneously, the external gear on the connecting rod engages with the spur gear to synchronously drive the limiting block closer to the bottom of the transmission unit, so that one end of the smear is lower than the smear disc, and the other end of the smear is higher than the smear disc, forming a second opening between them. The smear disc does not contact the surface to be smoothed; only the smear releases the surface from smoothing. By controlling the reducer to drive the transmission unit to rotate forward, the smear in the smoothing assembly performs the smoothing operation on the surface to be smoothed, achieving automatic switching of the smear working mode. There is no need for manual disassembly of the smear disc to perform smearing operation on the surface to be smoothed. The smoothing working mode switching is fast and flexible.

[0027] 5. The present invention offers diverse smoothing modes, allowing the smoothing machine to flexibly switch between different working modes of the trowel or trowel plate. This eliminates the need for operators to manually disassemble and reassemble the trowel plate to switch between the two working modes, saving operators time and downtime, thus providing convenience and further improving the smoothing machine's efficiency. Furthermore, the filling tube in the filling component, in conjunction with the nozzle, replenishes the slurry to the first opening formed on the trowel plate, guiding the replenished slurry below the trowel plate for rapid smoothing. This ensures high filling efficiency and prevents slurry from being stirred up onto the trowel plate. It also eliminates the need for operators to manually fill the slurry with a hand shovel, saving labor costs.

[0028] 6. The operator controls the water pump through the controller to flush the delivery pipe, through hole, connecting cylinder and filling pipe, so as to avoid the residual slurry inside them adhering to the pipe wall and affecting the delivery effect. The water delivered is sprayed out through the nozzle to moisten the base surface to be smoothed, so that the relatively dry area to be smoothed can be smoothed well. Attached Figure Description

[0053] The technical solutions provided by the various embodiments of this application are described below with reference to the accompanying drawings.

[0054] See Figures 1 to 17 The present invention provides a ride-on power trowel with slurry filling function, including a frame 1, and an engine 2, a main water tank 3, a seat 5, an oil tank 6 and a control lever 7 mounted on the frame 1. The frame 1 is also connected to a power trowel assembly and a slurry filling assembly. An adjusting roller 18 is connected between the power trowel assembly and the filling assembly. The adjusting roller 18 is rotatably connected to the frame 1.

[0055] The smoothing assembly includes a transmission part 17 rotatably mounted on a frame 1. The transmission part 17 has a plurality of connecting rods 901 arranged in a circular array. The connecting rods 901 are connected to the smears 9. The connecting rods 901 are connected to the internal gears 903 located inside the transmission part 17. The adjusting roller 18 is coaxially mounted with an active adjusting wheel and a driven adjusting wheel 1802 located inside the transmission part 17. The transmission part 17 is connected to an adjusting motor 19 that is connected to the active adjusting wheel. The transmission part 17 is connected to a smearing disc 8. The smearing disc 8 is provided with a mating hole 801 for accommodating the smears 9.

[0056] The smoothing assembly drives the active adjusting wheel and the adjusting roller 18 through the worm gear on the adjusting motor 19, so that the driven adjusting wheel 1802 on the adjusting roller 18 drives the internal gear 903 to rotate, so that the connecting rod 901 drives the smear 9 to flip in the mating hole 801 of the smearing plate 8, so that a first opening 22 or a second opening 23 is formed between the smear 9 and the smearing plate 8.

[0057] The slurry filling assembly includes a slurry tank 12 and a slurry pump 13 mounted on the frame 1. The slurry tank 12 is connected to a delivery pipe 15 via the slurry pump 13. The delivery pipe 15 is connected to a connecting part 1501, which is rotatably connected to one end of an adjusting roller 18. The other end of the adjusting roller 18 is connected to a connecting cylinder 1702 inside the transmission part 17. The connecting cylinder 1702 is connected to a filling pipe 1703 mounted on a trowel 8. The adjusting roller 18 has a through hole 1801 that communicates with the filling pipe 1703 and the delivery pipe 15. The slurry in the slurry tank 12 in the slurry filling assembly flows through the through hole 1801 into the connecting cylinder 1702. The slurry in the connecting cylinder 1702 is sprayed out through the nozzle 1704 of the filling pipe 1703 into the first opening 22. The sprayed slurry is guided by the trowel 9 to the bottom of the trowel 8 and then filled and smoothed.

[0058] See Figure 2 and Figures 8 to 17 The controller 10 has three operating modes for the smoothing component: smoothing disc mode 8, smoothing pad mode 9, and filling mode.

[0059] See Figures 8 to 12 The initial state of the smoothing component is in the smoothing disk 8 mode, that is, the smoothing piece 9 is set parallel to the smoothing disk 8, the smoothing piece 9 does not flip in the mating hole 801, the bottom of the smoothing piece 9 is basically flush with the bottom of the smoothing disk 8, and both are in contact with the base surface to be smoothed, so that the two cooperate to form a complete smoothing disk 8 mode, thereby performing a smoothing operation on the base surface that needs to be smoothed.

[0060] See Figures 8 to 15When the operator triggers the filling mode via controller 10, controller 10 controls the adjusting motor 19 to rotate forward, causing the worm gear to drive the adjusting roller 18 on the worm wheel to rotate forward. The forward rotation of the adjusting roller 18 causes the connecting rod 901 to rotate in reverse, and the squeegee 9 flips within the mating hole 801. At the same time, the external gear 902 on the connecting rod 901, in conjunction with the spur gear 803, synchronously drives the limiting block 802 away from the bottom end of the transmission part 17, thereby causing one end of the squeegee 9 to be higher than the squeegee disc 8, and forming a first opening 22 between them. The other end is almost flush with the trowel plate 8. The speed reducer 16 drives the transmission part 17 to reverse and controls the grout pump 13 to deliver grout into the filling pipe 1703. The grout in the filling pipe 1703 is then sprayed out through the nozzle 1704 to the first opening 22. At this time, the trowel 9 does not contact the base surface to be smoothed, and the trowel plate 8 contacts the base surface to be smoothed. The sprayed grout is guided by the inclined trowel 9 to the lower end of the trowel plate 8 and then smoothed, thereby achieving the effect of flexibly and timely filling the areas on the base surface that need to be replenished with grout.

[0061] See Figures 8 to 17 When the operator triggers the smear 9 mode via controller 10, controller 10 controls the adjusting motor 19 to reverse, causing the worm gear to drive the adjusting roller 18 on the worm wheel to reverse. The reverse rotation of the adjusting roller 18 causes the connecting rod 901 to rotate forward, and the smear 9 flips within the mating hole 801. Simultaneously, the external gear 902 on the connecting rod 901 engages with the spur gear 803 to synchronously drive the limiting block 802 closer to the bottom of the transmission part 17, so that one end of the smear 9 is lower than the smear disk 8, and the other end of the smear 9 is higher than the smear disk 8, with a second opening 23 formed between them. The smear disk 8 does not contact the base surface to be smoothed; only the smear 9 releases the base surface from smoothing. By controlling the reducer 16 to drive the transmission part 17 to rotate forward, the smear 9 in the smoothing assembly moves towards the base surface to be smoothed. The surface is smoothed using the present invention, which offers diverse smoothing modes. The smoothing machine can flexibly switch between different working modes of the trowel 9 and the trowel disc 8 without the need for operators to manually disassemble and assemble the trowel disc 8 to switch between the two working modes. This saves operators the time spent disassembling and assembling the trowel disc 8 and the downtime of the smoothing machine, bringing convenience to operators and further improving the working efficiency of the smoothing machine. In addition, the filling tube 1703 in the filling component, together with the nozzle 1704, replenishes the slurry to the first opening 22 formed on the trowel disc 8. The replenished slurry is guided to the bottom of the trowel disc 8 for rapid smoothing. The filling efficiency is high, and there is no situation where it is stirred up and falls onto the trowel disc 8. It also eliminates the need for operators to manually fill the surface with a hand shovel, saving labor costs.

[0062] See Figures 4 to 7The smoothing assembly also includes a reducer 16 mounted on the frame 1. The reducer 16 is connected to the engine 2 via a transmission. The engine 2 drives the transmission unit 17 to operate via the reducer 16. One end of the adjusting roller 18 is rotatably connected to the frame 1 and extends to the upper end of the frame 1. Both the main water tank 3 and the oil tank 6 are equipped with connecting frames 1503. The connecting frames 1503 are inserted into the T-slots 1502. The connecting frames 1503 are connected to the conveying pipe 15 and are rotatably connected to the adjusting roller 18.

[0063] See Figures 8 to 12 The smoothing assembly also includes multiple limiting blocks 802 arranged in a circumferential array on the smoothing disk 8. The limiting blocks 802 are provided with straight teeth 803 and limiting grooves 804. The outer circumferential array of the transmission part 17 has multiple connecting blocks 1705. The transmission part 17 is slidably inserted into the limiting grooves 804 of the limiting blocks 802 through the connecting blocks 1705. An external gear 902 located outside the transmission part 17 is movably arranged on the connecting rod 901. The connecting rod 901 is provided with a clearance groove. The external gear 902 is slidably connected to the connecting rod 901 through the clearance groove. The connecting rod 901 is meshed with the straight teeth 803 on the limiting blocks 802 through the external gear 902.

[0064] See Figures 2 to 17 The slurry plate 8 also has a clearance hole corresponding to the bottom of the transmission part 17. When the connecting rod 901 rotates, the external gear 902 drives the limiting block 802 on the spur gear part 803 and the slurry plate 8 to move along the axial direction of the transmission part 17. The slurry filling assembly also includes a secondary water tank 11 set on the slurry tank 12. The secondary water tank 11 is connected to a water supply pump 14. The water supply pump 14 is connected to the delivery pipe 15 through a first one-way valve. The operator controls the water supply pump 14 to work through the controller 10, so that the delivery pipe 15, the through hole 1801, the connecting cylinder 1702 and the filling pipe 1703 are flushed, so as to avoid the residual slurry inside them from adhering to the pipe wall and affecting the delivery effect. In addition, the water delivered is sprayed out through the nozzle 1704 to apply a moistening effect to the base surface to be smoothed, so as to make it more... A dry area to be smoothed can achieve a good smoothing effect; the slurry pump 13 and the delivery pipe 15 are connected by a second one-way valve; the transmission part 17 has multiple connecting holes 1701 arranged in a circumferential array; one end of the connecting rod 901 passes through the connecting hole 1701 and is placed inside the transmission part 17; the nozzle 1704 of the filling tube 1703 is located at the side end of the mating hole 801; there is a clearance area between the filling tube 1703 and the smearing plate 8; the output end of the adjusting motor 19 is connected to a worm gear; the active adjusting wheel is set as a worm wheel that mates with the worm gear; a storage battery is installed inside the transmission part 17; the adjusting motor 19 is connected to the storage battery; a controller 10 is connected to the seat 5; the engine 2, the slurry pump 13, the water pump 14, the reducer 16, the adjusting motor 19 and the controller 10 are connected by signals.

[0065] This embodiment provides a ride-on power trowel with slurry filling function:

[0066] The controller 10 has three operating modes for the smoothing component: smoothing disc mode 8, smoothing pad mode 9, and filling mode.

[0067] The initial state of the smoothing component is in the smoothing disk 8 mode, that is, the smoothing piece 9 is set parallel to the smoothing disk 8, the smoothing piece 9 does not flip in the mating hole 801, the bottom of the smoothing piece 9 is basically flush with the bottom of the smoothing disk 8, and both are in contact with the base surface to be smoothed, so that the two cooperate to form a complete smoothing disk 8 mode, thereby performing a smoothing operation on the base surface to be smoothed.

[0068] When the operator triggers the filling mode via controller 10, controller 10 controls the adjusting motor 19 to rotate forward, causing the worm gear to drive the adjusting roller 18 on the worm wheel to rotate forward. The forward rotation of the adjusting roller 18 causes the connecting rod 901 to rotate in reverse, and the squeegee 9 flips within the mating hole 801. Simultaneously, the external gear 902 on the connecting rod 901 engages with the spur gear 803 to synchronously drive the limiting block 802 away from the bottom end of the transmission part 17, thereby causing one end of the squeegee 9 to be higher than the squeegee disc 8, and forming a first opening 22 between them. The other end is almost flush with the trowel plate 8. The reducer 16 drives the transmission part 17 to reverse and controls the grout pump 13 to deliver grout into the filling pipe 1703. The grout in the filling pipe 1703 is then sprayed out through the nozzle 1704 to the first opening 22. At this time, the trowel 9 does not contact the base surface to be smoothed, and the trowel plate 8 contacts the base surface to be smoothed. The sprayed grout is guided by the inclined trowel 9 to the lower end of the trowel plate 8 and then smoothed, thereby achieving the effect of flexibly and timely filling the places on the base surface that need to be replenished with grout.

[0069] When the operator triggers the smear 9 mode via controller 10, controller 10 controls the adjusting motor 19 to reverse, causing the worm gear to drive the adjusting roller 18 on the worm wheel to reverse. The reverse rotation of the adjusting roller 18 causes the connecting rod 901 to rotate forward, and the smear 9 flips within the mating hole 801. Simultaneously, the external gear 902 on the connecting rod 901 engages with the spur gear 803 to synchronously drive the limiting block 802 closer to the bottom of the transmission part 17, so that one end of the smear 9 is lower than the smear disk 8, and the other end of the smear 9 is higher than the smear disk 8, forming a second opening 23 between them. The smear disk 8 does not contact the base surface to be smoothed; only the smear 9 releases the base surface from smoothing. By controlling the reducer 16 to drive the transmission part 17 to rotate forward, the smear 9 in the smoothing assembly moves towards the surface to be smoothed. The present invention provides a variety of smoothing modes for the flat base surface, allowing the smoothing machine to flexibly switch between different working modes of the trowel 9 and the trowel 8. This eliminates the need for operators to manually disassemble and assemble the trowel 8 to switch between the two working modes, saving operators' time and downtime for the smoothing machine, thus providing convenience for operators and further improving the working efficiency of the smoothing machine. Furthermore, the filling tube 1703 in the filling component, in conjunction with the nozzle 1704, replenishes the slurry to the first opening 22 formed on the trowel 8, allowing the replenished slurry to be guided to the bottom of the trowel 8 for rapid smoothing. The filling efficiency is high, and there is no situation where the slurry falls onto the trowel 8. It also eliminates the need for operators to manually fill the slurry with a hand shovel.
