Description

Technical Field

[0001] This invention relates to the field of engineering machinery, and more specifically, to a power trowel. Background Technology

[0002] A power trowel, also known as a finishing machine, primarily consists of a gasoline engine-driven trowel rotor. Trowels are mounted on the underside of a cross-shaped section in the center of the rotor. The trowels are tilted in the same direction as the rotor's rotation, which is driven by a V-belt from the gasoline engine. To operate, first start the engine, then grasp the control handles. Pushing both handles forward simultaneously moves the machine forward, while pulling them backward moves it backward. On average, it can finish 100-300 meters per hour. 2 Compared with manual polishing, it can improve work efficiency by more than 30 times.

[0003] Existing power trowels have the following problems:

[0004] 1. Ride-on power trowels typically use gasoline or diesel engines, resulting in high fuel costs and high daily maintenance costs for components such as air filters, oil filters, engine oil, and coolant tanks.

[0005] 2. Ordinary ride-on power trowels require operators to sit on the equipment for extended periods, which can easily lead to driver fatigue.

[0006] 3. There are safety hazards when using it manually on concrete floors (rooftops) in special situations. Summary of the Invention

When the first remote control stick swings left and right, the first remote control stick drives the first swing member to swing up and down. The first mating protrusion cooperates with the upper or lower hole wall of the first mating hole to lift or press down the first extension plate, so that the corresponding side of the polishing member is lifted or pressed down. When the first remote control stick swings back and forth, the first mating protrusion and the hole wall of the first mating hole do not interfere with each other. The second transmission assembly includes an extension member extending along the left and right direction of the machine frame. The device comprises a first rotating shaft, a transition plate at the end of the first rotating shaft, a second swing member connected to the first rotating shaft and capable of swinging up and down, and a second extension member mounted on the first gearbox. The second extension member includes a second extension plate connected to the first gearbox and extending to the left or right, and a second mating protrusion at the end of the second extension plate. The second swing member has a first pivot shaft in the middle, one end of the second swing member is connected to the first rotating shaft, and the other end of the second swing member is provided with a second mating post. The lower end of the second mating post is a second mating ball head, and the second mating ball head is provided with a second mating hole. The second mating protrusion extends into the second mating hole. The pivot end of the first swing member is connected to the transition plate. When the first remote control stick swings back and forth, the first remote control stick drives the first rotating shaft to pivot through the transition plate, and the second swing member swings up and down. The second mating protrusion cooperates with the upper or lower hole wall of the second mating hole to lift or press down the second extension plate, so that the corresponding side of the polishing member is lifted or pressed down. When the first remote control stick swings left and right, the first rotating shaft does not move with the first remote control stick.

[0017] In one embodiment, the power trowel includes a third transmission assembly, which includes a second rotating shaft extending along the left-right direction m of the machine frame and connected to a second remote control stick, a third swing member connected to the second rotating shaft and capable of swinging up and down, and a third extension member disposed on a second gearbox.

[0022] By applying the technical solution of this invention, when using a power trowel, the operator can output remote control information via a remote control according to the site conditions. After receiving the remote control information, the control device controls the first and second drive devices to perform corresponding actions, thereby achieving overall movement control of the power trowel. Therefore, by applying the technical solution of this invention, the operator does not need to sit on the power trowel, thus avoiding the problem of fatigue driving. Furthermore, when performing power troweling operations on concrete floors in special situations (such as rooftops), the safety hazard is eliminated because the operator is not on the power trowel. In addition, in this invention, the power supply device supplies power to the first drive device, the second drive device, and the control device, making the power trowel electrically driven. Therefore, it does not require expensive fuel, resulting in low daily maintenance costs.

[0037] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0038] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0039] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such terms can be used interchangeably where appropriate for the embodiments of the invention described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0040] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0041] like Figures 1 to 9 As shown, the power trowel of Embodiment 1 includes: a machine frame 10, two power troweling components 20, a first drive device 30, a second drive device 40, a control device 50, and a power supply device 110. The two power troweling components 20 are arranged at intervals along the left-right direction m of the machine frame 10. Each power troweling component 20 includes a reduction gearbox and a power trowel 22 pivotally disposed below the reduction gearbox. Both reduction gearboxes are swayably disposed along the front-back direction n and the left-right direction m of the machine frame 10. The first drive device 30 is drivenly connected to the two power trowels 22 to drive the power trowels 22 to rotate. The second drive device 40 is disposed on the machine frame 10 and is drivenly connected to the two reduction gearboxes to drive the two reduction gearboxes to oscillate. The control device 50 is disposed on the machine frame 10 and controls the operation of the first drive device 30 and the second drive device 40 according to received remote control information. The power supply device 110 supplies power to the first drive device 30, the second drive device 40, and the control device 50.

[0042] Applying the technical solution of Embodiment 1, when using the power trowel, the operator can output remote control information via a remote control according to the site conditions. After receiving the remote control information, the control device 50 controls the first drive device 30 and the second drive device 40 to perform corresponding actions, thereby achieving movement control of the entire power trowel. Therefore, applying the technical solution of Embodiment 1 eliminates the need for the operator to sit on the power trowel, thus avoiding the problem of fatigue driving. Furthermore, when performing power troweling operations on concrete floors in special situations (such as rooftops), the safety hazard is eliminated because the operator is not on the power trowel. In addition, in Embodiment 1, the power supply device 110 supplies power to the first drive device 30, the second drive device 40, and the control device 50, making the power trowel electrically driven. Therefore, it does not require expensive fuel, resulting in low daily maintenance costs.

[0043] The following describes in detail how the power trowel in Embodiment 1 moves forward, backward, left, and right. The left-side power trowel 22 always rotates counterclockwise, while the right-side power trowel 22 always rotates clockwise.

[0044] Forward: The second drive device 40 drives the left-side polishing component 22 to swing to the left, increasing the contact force between the right side of the polishing component 22 and the ground. At this time, the ground exerts a forward force on the polishing machine. Simultaneously, the second drive device 40 drives the right-side polishing component 22 to swing to the right, increasing the contact force between the left side of the polishing component 22 and the ground. At this time, the ground also exerts a forward force on the polishing machine, thus allowing the polishing machine to move forward.

[0045] Reverse: The second drive device 40 drives the left-side polishing component 22 to swing to the right, increasing the contact force between the left side of the polishing component 22 and the ground. At this time, the ground exerts a backward force on the polishing machine. The second drive device 40 also drives the right-side polishing component 22 to swing to the left, increasing the contact force between the right side of the polishing component 22 and the ground. At this time, the ground also exerts a backward force on the polishing machine, thus allowing the polishing machine to move backward.

[0046] Leftward movement: The second drive device 40 drives the left-side polishing component 22 to swing backward, increasing the contact force between the front side of the polishing component 22 and the ground. At this time, the ground exerts a force to the left on the polishing machine, allowing the polishing machine to move to the left.

[0047] Rightward movement: The second drive device 40 drives the left-side polishing component 22 to swing forward, increasing the contact force between the rear side of the polishing component 22 and the ground. At this time, the ground exerts a force to the right on the polishing machine, allowing the polishing machine to move to the right.

[0048] like Figures 1 to 4As shown, in Embodiment 1, the two reduction gearboxes are a first reduction gearbox 211 and a second reduction gearbox 212. The power trowel also includes a first remote control lever 60 and a second remote control lever 70. The first remote control lever 60 is drivenly connected to the first reduction gearbox 211. The second remote control lever 70 is drivenly connected to the second reduction gearbox 212. The second drive device 40 includes a first drive assembly 41 and a second drive assembly 42 that are independent of each other. The first drive assembly 41 drives the first reduction gearbox 211 to swing through the first remote control lever 60, and the second drive assembly 42 drives the second reduction gearbox 212 to swing through the second remote control lever 70. Since the first drive assembly 41 and the second drive assembly 42 are independent of each other, the swing amplitude of the first remote control stick 60 and the second remote control stick 70 can be adjusted independently. This allows the swing amplitude of the first reduction gearbox 211 and the second reduction gearbox 212, which are driven and swung by the first remote control stick 60 and the second remote control stick 70, to be adjusted independently. As a result, the forces that the troweling parts 22 on the left and right sides have in contact with the ground can be different, thereby enabling better control of the movement path of the troweling machine so that the forward direction of the troweling machine is not limited to the four directions of forward, backward, left, and right.

[0049] like Figures 1 to 4 As shown, in Embodiment 1, the first driving assembly 41 includes a first module 411, a second module 412, and a first mating structure 413 that are perpendicular to each other. The second module 412 is connected to the first slider 414 of the first module 411. The first mating structure 413 is disposed on the second slider 415 of the second module 412 and cooperates with the first remote control stick 60. The control device 50 controls the sliding of the first slider 414 and the second slider 415 according to the received remote control information. The above structure enables the first remote control stick 60 to swing in the front-back and left-right directions, thereby realizing the purpose of the left-side polishing component 22 swinging in the front-back and left-right directions. The above structure has the advantages of simple structure, low cost, and precise control.

[0050] like Figures 1 to 4As shown, in Embodiment 1, the second driving component 42 includes a third module 421 and a second mating structure 423 disposed on the third slider 422 of the third module 421. The second mating structure 423 cooperates with the second remote control stick 70, and the control device 50 controls the third slider 422 to slide according to the received remote control information. This structure allows the second remote control stick 70 to swing in the front-back direction, thereby enabling the right-side polishing component 22 to swing left and right. This structure has the advantages of simple structure, low cost, and precise control. Of course, in other embodiments not shown in the figure, the second driving component may also include a fourth module, with the relationship between the third and fourth modules being consistent with the relationship between the first and second modules. This allows the second remote control stick 70 to also swing in the front-back and left-right directions, thereby enabling the right-side polishing component 22 to swing back-back and left-right. This structure also has the advantages of simple structure, low cost, and precise control. However, although this embodiment offers more precise control, its cost is relatively higher than Embodiment 1.

[0051] like Figures 1 to 4 As shown, in Embodiment 1, the second drive device 40 further includes a module frame 43, which is mounted on the machine frame 10. The first module 411 and the third module 421 are connected to the module frame 43. This structure is simple and provides support for the first module 411, the second module 412, and the third module 421. Furthermore, because the support structure is a frame structure, the overall weight and cost of the power trowel are reduced.

[0052] like Figures 4 to 9 As shown, in Embodiment 1, the polishing machine further includes a first transmission assembly 80. The first transmission assembly 80 includes a first extension member 81 disposed on the first reduction gearbox 211 and a first swing member 82 that can swing up and down. The first extension member 81 is located on the front side of the first reduction gearbox 211, and the first swing member 82 is connected to the first remote control lever 60. When the first remote control lever 60 swings left and right, the first remote control lever 60 drives the first swing member 82 to swing up and down. The first extension member 81 presses down or lifts up with the first swing member 82 to press down or lift up the corresponding side of the polishing member 22 (i.e., to realize the back-and-forth swing of the left side of the polishing member 22). When the first remote control lever 60 swings back and forth, the first swing member 82 and the first extension member 81 do not affect each other. The above structure is simple and has high reliability. Of course, in other embodiments not shown in the figure, the first extension member 81 can also be located on the rear side of the first reduction gearbox 211.

[0053] like Figure 4 , Figure 5 and Figure 10As shown, in Embodiment 1, the first extension member 81 includes a first extension plate 811 connected to the first reduction gearbox 211 and extending forward, and a first mating post 812 vertically disposed on the first extension plate 811. The upper end of the first mating post 812 is a first mating ball head 813, which has a first mating hole. One end of the first swing member 82 is a pivot end connected to the first remote control lever 60, and the other end of the first swing member 82 has a first mating protrusion 821 extending into the first mating hole. The above structure is simple and highly reliable. Of course, in other embodiments not shown in the figure, the first extension plate 811 can also extend backward.

[0054] like Figures 4 to 7 As shown, in Embodiment 1, the polishing machine includes a second transmission assembly 90. The second transmission assembly 90 includes a first rotating shaft 91 extending along the left-right direction m of the machine frame 10 and connected to a first remote control lever 60, a second swing member 92 connected to the first rotating shaft 91 and capable of swinging up and down, and a second extension member 93 disposed on the first reduction gearbox 211. The second extension member 93 is located on the right side of the first reduction gearbox 211. When the first remote control lever 60 swings back and forth, the first remote control lever 60 drives the first rotating shaft 91 to pivot, and the second swing member 92 swings up and down. The second extension member 93 presses down or lifts up with the second swing member 92 to press down or lift up the corresponding side of the polishing member 22 (i.e., to realize the left-right swing of the left-side polishing member 22). When the first remote control lever 60 swings left and right, the first rotating shaft 91 does not move with the first remote control lever 60. Of course, in other embodiments not shown in the figure, the second extension member 93 may also be located on the left side of the first reduction gearbox 211.

[0055] like Figures 4 to 7 As shown, in Embodiment 1, the second extension member 93 includes a second extension plate 931 connected to the first reduction gearbox 211 and extending to the right, and a second mating protrusion 932 disposed at the end of the second extension plate 931. The second swing member 92 has a first pivot shaft 921 in the middle, one end of the second swing member 92 is connected to the first pivot shaft 91, and the other end of the second swing member 92 is laterally provided with a second mating post 922. The lower end of the second mating post 922 is a second mating ball head 923, and a second mating hole is provided on the second mating ball head 923. The second mating protrusion 932 extends into the second mating hole. The above structure is simple and has high reliability. Of course, in other embodiments not shown in the figure, the second extension plate 931 can also extend to the left.

[0056] like Figures 4 to 7As shown, in Embodiment 1, the power trowel includes a third transmission assembly 100. The third transmission assembly 100 includes a second rotating shaft 101 extending along the left-right direction m of the machine frame 10 and connected to a second remote control lever 70; a third swing member 102 connected to the second rotating shaft 101 and capable of vertical swinging; and a third extension member 103 disposed on the second reduction gearbox 212. The third extension member 103 is located on the left side of the second reduction gearbox 212. When the second remote control lever 70 swings back and forth, the second remote control lever 70 drives the second rotating shaft 101 to pivot, causing the third swing member 102 to swing up and down. The third extension member 103, along with the third swing member 102, presses down or lifts up, causing the corresponding side of the power trowel 22 to press down or lift up (i.e., realizing the left-right swinging of the right side of the power trowel 22). The above structure is simple and highly reliable. Of course, in other embodiments not shown in the figure, the third extension member 103 can also be located on the right side of the second reduction gearbox 212.

[0057] like Figures 4 to 7 As shown, in Embodiment 1, the third extension member 103 includes a third extension plate 104 connected to the second reduction gearbox 212 and extending to the left, and a third mating protrusion 105 disposed at the end of the third extension plate 104. The third swing member 102 has a second pivot shaft 108 in the middle. One end of the third swing member 102 is connected to the second pivot shaft 101, and the other end of the third swing member 102 is provided with a third mating post 106. The lower end of the third mating post 106 is a third mating ball head 107, and a third mating hole is provided on the third mating ball head 107. The third mating protrusion 105 extends into the third mating hole. The above structure is simple and has high reliability. Of course, in other embodiments not shown in the figure, the third extension plate 104 may also extend to the right.

[0058] like Figures 4 to 7 As shown, in Embodiment 1, the second transmission assembly 90 further includes a transition plate 94 disposed at the end of the first rotating shaft 91. The pivot end of the first swing member 82 is connected to the transition plate 94. When the first remote control 60 swings back and forth, the first remote control 60 drives the first rotating shaft 91 to pivot through the transition plate 94, and the second swing member 92 swings up and down.

[0059] The following is a detailed explanation of how a power trowel equipped with a first transmission assembly 80, a second transmission assembly 90, and a third transmission assembly 100 moves forward, backward, left, and right:

[0060] Forward: The operator remotely moves the first slider 414 of the first module 411 forward. At this time, the first remote control lever 60 swings forward, and the first rotating shaft 91 pivots accordingly. During the rotation, the first rotating shaft 91 drives the second mating post 922 of the second swing member 92 to press down. The upper wall of the second mating hole of the second mating head 923 abuts against the second mating protrusion 932, causing the second mating protrusion 932 to move down. The second mating protrusion 932 then drives the second extension plate 931 to press down, so that the left side of the left polishing member 22 is lifted and the right side is pressed down, thereby giving the left polishing member 22 a forward force from the ground, so that the left polishing member can move forward. Simultaneously, the operator remotely controls the third slider 422 of the third module 421 to move forward. At this time, the second remote control lever 70 swings forward, and the second rotating shaft 101 pivots accordingly. During the rotation, the second rotating shaft 101 drives the third mating post 106 of the third swing member 102 to press down. The upper wall of the third mating hole of the third mating ball head 107 abuts against the third mating protrusion 105, thereby driving the third mating protrusion 105 to press down. The third mating protrusion 105 then drives the third extension plate 104 to press down, so that the right side of the right-side polishing member 22 is lifted and the left side is pressed down, thereby giving the right-side polishing member 22 a forward force from the ground. In this way, the right-side polishing member can also move forward at the same time, ensuring that the entire polishing machine moves forward.

[0061] Reverse: The operator remotely moves the first slider 414 of the first module 411 backward. At this time, the first remote control lever 60 swings backward, and the first rotating shaft 91 pivots accordingly. During the rotation, the first rotating shaft 91 drives the second mating post 922 of the second swing member 92 to move upward. The lower wall of the second mating hole of the second mating head 923 abuts against the second mating protrusion 932, thereby driving the second mating protrusion 932 to move upward. The second mating protrusion 932 then drives the second extension plate 931 to lift, so that the right side of the left polishing member 22 is lifted and the left side is pressed down, thereby causing the ground to exert a backward force on the left polishing member 22, so that the left polishing member can move backward. Simultaneously, the operator remotely controls the third slider 422 of the third module 421 to move backward. At this time, the second remote control lever 70 swings backward, and the second rotating shaft 101 pivots accordingly. During the rotation, the second rotating shaft 101 drives the third mating post 106 of the third swinging member 102 to move upward. The lower wall of the third mating hole of the third mating ball head 107 abuts against the third mating protrusion 105, thereby driving the third mating protrusion 105 to move upward. The third mating protrusion 105 then drives the third extension plate 104 to lift, so that the left side of the right-side polishing member 22 is lifted and the right side is pressed down, thereby causing the ground to exert a backward force on the right-side polishing member 22. In this way, the right-side polishing member can also move backward at the same time, ensuring that the entire polishing machine moves backward.

[0062] Leftward movement: The operator remotely moves the second slider 415 of the second module 412 to the left. At this time, the first remote control lever 60 swings to the left, causing the first swinging member 82 to swing counterclockwise. The first mating protrusion 821 then presses down, pressing down on the lower wall of the first mating hole to press down the first extension plate 811. The downward pressure of the first extension plate 811 causes the rear side of the left-side polishing member 22 to lift and the front side to press down, thereby causing the ground to exert a leftward force on the left-side polishing member 22, enabling the polishing member 22 to move to the left.

[0063] Rightward movement: The operator remotely moves the second slider 415 of the second module 412 to the right. At this time, the first remote control lever 60 swings to the right, causing the first swinging member 82 to swing clockwise. The first mating protrusion 821 then rises, abutting against the upper wall of the first mating hole to lift the first extension plate 811. The lifting of the first extension plate 811 causes the front side of the left-side polishing member 22 to rise and the rear side to press down, thereby causing the ground to exert a rightward force on the left-side polishing member 22, enabling the polishing member 22 to move to the right.

[0064] It should be noted that, as Figure 7 As shown, in Embodiment 1, the second swing member 92 actually includes a first transmission rod and a first lever. The first end of the first transmission rod is connected to the first rotating shaft 91, the second end of the first transmission rod is connected to the first end of the first lever, and the second end of the first lever is connected to the second mating post 922. The pivot axis of the first lever is the first pivot axis 921. When the operator remotely moves the first slider 414 of the first module 411 forward, the first remote control 60 swings forward, and the first rotating shaft 91 pivots accordingly. During rotation, the first rotating shaft 91 drives the second end of the first transmission rod to lift, which in turn drives the first end of the first lever to lift, thereby causing the second end of the first lever to press down, ultimately achieving the purpose of pressing down the second mating post 922. When the operator remotely moves the first slider 414 of the first module 411 backward, the first remote control lever 60 swings backward, and the first rotating shaft 91 pivots accordingly. During the rotation, the first rotating shaft 91 drives the second end of the first transmission rod to press down, and the second end of the first transmission rod drives the first end of the first lever to press down, thereby lifting the second end of the first lever, and finally achieving the purpose of moving the second mating column 922 upward.

[0065] Similarly, as Figure 7As shown, in Embodiment 1, the third swing member 102 actually includes a second transmission rod and a second lever. The first end of the second transmission rod is connected to the second rotating shaft 101, the second end of the second transmission rod is connected to the first end of the second lever, and the second end of the second lever is connected to the third mating post 106. The pivot axis of the second lever is the second pivot axis 108. When the operator remotely moves the third slider 422 of the third module 421 forward, the second remote control 70 swings forward, and the second rotating shaft 101 pivots accordingly. During the rotation, the second rotating shaft 101 drives the second end of the second transmission rod to lift, and the second end of the second transmission rod drives the first end of the second lever to lift, thereby causing the second end of the second lever to press down, ultimately achieving the purpose of pressing down the third mating post 106. When the operator remotely moves the third slider 422 of the third module 421 backward, the second remote control lever 70 swings backward, and the second rotating shaft 101 pivots accordingly. During the rotation, the second rotating shaft 101 drives the second end of the second transmission rod to press down, and the second end of the second transmission rod drives the first end of the second lever to press down, thereby lifting the second end of the second lever, and finally achieving the purpose of moving the third mating column 106 upward.

[0066] like Figure 3 As shown, in Embodiment 1, the first driving device 30 includes a driver 31 and a drive motor 32. The driver 31 is electrically connected to the control device 50 to control the speed of the drive motor 32. The power trowel also includes a fourth transmission assembly 120, through which the drive motor transmits driving force to the two power trowels 22. This structure allows for more precise control of the power trowel by the operator; furthermore, using one drive motor to simultaneously drive two power trowels reduces production costs.

[0067] Specifically, in Embodiment 1, the fourth transmission assembly 120 includes a pulley, a belt, and a cross coupling. Power is transmitted to the cross coupling via the belt, and the cross coupling is connected to the first reduction gearbox 211 and the second reduction gearbox 212, ultimately realizing the power output of the polishing component 22.

[0068] Preferably, in Embodiment 1, the polishing component 22 includes a trowel and a trowel plate detachably disposed below the trowel.

[0069] like Figure 1 and Figure 3 As shown, in Embodiment 1, the power trowel further includes a protective frame 130, which covers the outside of the first drive device 30 and the power supply device 110. This structure provides protection for the first drive device 30, the control device 50, and the power supply device 110.

[0070] like Figure 1 , Figures 8 to 10As shown, in Embodiment 1, the power trowel further includes: a cross shaft 140, comprising a third pivot shaft 141 extending in the front-rear direction n and a fourth pivot shaft 142 extending in the left-right direction m. The fourth pivot shaft 142 is connected below the third pivot shaft 141. The third pivot shaft 141 is pivotally mounted on the machine frame 10. The gearbox has a lifting lug, and the gearbox is pivotally connected to the fourth pivot shaft 142 via the lifting lug. The above structure is simple and easy to implement.

[0071] The difference between the power trowel in Embodiment 2 and the power trowel in Embodiment 1 lies only in the swing direction of the gearbox. Specifically, in Embodiment 2, one of the two gearboxes is swingably arranged along the front-back direction n and the left-right direction m of the machine frame 10, and the other of the two gearboxes is swingably arranged along the left-right direction m of the machine frame 10.

[0073] The remote-controlled power trowel of the present invention reduces the use and maintenance costs of ordinary power trowels, improves construction efficiency, and makes applications possible in more special occasions.
