Description

Technical Field

[0001] This utility model belongs to the field of power trowel technology, specifically relating to a new energy-powered power trowel. Background Technology

[0002] A power trowel is a tool used for roughing and smoothing concrete surfaces. Machine-applied surfaces are smoother and flatter than those applied manually, significantly improving the density and wear resistance of the concrete surface. It also greatly increases work efficiency compared to manual labor. Power trowels are widely used for leveling, smoothing, and finishing concrete surfaces in high-standard factories, warehouses, parking lots, plazas, airports, and framed buildings.

[0003] Depending on the flatness of the ground, workers need to control the angle adjustment mechanism to change the tilt angle of the trowel relative to the ground, thereby smoothing the ground with the trowel. Common methods of controlling the angle adjustment mechanism usually require pressing down a lever to adjust the trowel's tilt angle. During this process, the user must control both the downward pressure and the movement of the power trowel, which places high demands on the operator and is inconvenient to operate. Utility Model Content

[0004] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a new energy-powered power trowel.

[0005] To achieve the above and other related objectives, this utility model provides a new energy power trowel, which includes a housing, a control lever mounted on the housing, a mounting cover mounted on the housing for housing a battery, a battery mounted inside the mounting cover, a motor mounted inside the housing and electrically connected to the battery, a reducer mounted inside the housing and connected to the output shaft of the motor, a crossbar mounted on the output shaft of the reducer, a blade holder mounted on the crossbar, a blade mounted on the blade holder, a carriage bolt mounted on the blade holder for adjusting the blade's inclination angle, a blade pressure plate that is movably sleeved outside the crossbar and abuts against the top of the carriage bolt, a bearing pressure plate that is movably sleeved outside the crossbar and located above the blade pressure plate, a first bearing disposed between the blade pressure plate and the bearing pressure plate, and a fork assembly disposed on the housing for pressing down the bearing pressure plate;

[0006] The fork assembly includes a fork and a vertical lead screw. The middle part of the fork is rotatably connected to the housing via a connecting pin. The first end of the fork abuts against the top surface of the bearing pressure plate. The second end of the fork is provided with a vertical threaded hole through which the lead screw passes and is screwed to the lead screw. The housing is provided with a vertical hole through which the lead screw passes. The lead screw is rotatably connected to the vertical hole via a second bearing. The top end of the lead screw is provided with a handwheel that drives the lead screw to rotate.

[0007] Optionally, the inner wall surface of the second bearing is fixedly connected to the lead screw, and the outer wall surface of the second bearing is fixedly connected to the inner wall surface of the vertical hole.

[0008] Optionally, the mounting cover has a mounting slot for inserting and connecting the battery, and the mounting cover has multiple heat dissipation holes.

[0009] Optionally, the battery has a handle on top.

[0010] Optionally, the joystick is a telescopic joystick, and the joystick is equipped with a control switch, a speed adjustment knob and a control handle.

[0011] Optionally, the fork includes a first clamping plate and a second clamping plate that are arranged opposite to each other and fixedly connected. A transition block is provided between the second ends of the first clamping plate and the second clamping plate and can be rotatably clamped between the first clamping plate and the second clamping plate. A vertical threaded hole is provided on the transition block. The two sides of the transition block are rotatably connected to the first clamping plate and the second clamping plate respectively through a rotating shaft.

[0012] As described above, the new energy-powered power trowel of this invention has the following beneficial effects: When using the new energy-powered power trowel of this invention, the battery is placed inside the mounting cover, and the battery provides power support for the operation of the trowel. Turning the handwheel drives the lead screw to rotate around the second bearing. The rotation of the lead screw causes the second end of the fork to move upward. At this time, the first end of the fork rotates downward around the connecting pin. The first end of the fork pushes the blade pressure plate and bearing pressure plate downward, and the bearing pressure plate pushes the carriage bolt downward, thereby causing the blade to tilt to the required angle. Starting the motor drives the reducer to rotate, the reducer's electric crossbar rotates, and the crossbar drives the blade holder and blade to rotate, achieving the smoothing of the concrete. After the work is completed, the battery can be removed and charged. Alternatively, when the battery power is low, the battery can be replaced to continue working. Attached Figure Description

[0020] like Figure 1-4As shown, this embodiment provides a new energy power trowel 10, which includes a housing 11, a control lever 12 mounted on the housing 11, a mounting cover 13 mounted on the housing 11 for housing a battery 14, a battery 14 mounted inside the mounting cover 13, a motor 15 mounted inside the housing 11 and electrically connected to the battery 14, a reducer 16 mounted inside the housing 11 and connected to the output shaft of the motor 15, a crossbar 17 mounted on the output shaft of the reducer 16, and a blade mounted on the crossbar 17. The tool holder 18, the blade 19 mounted on the tool holder 18, the carriage bolt 20 mounted on the tool holder 18 for adjusting the inclination angle of the blade 19, the blade pressure plate 21 which is movably sleeved on the cross 17 and abuts against the top of the carriage bolt 20, the bearing pressure plate 22 which is movably sleeved on the cross 17 and located above the blade pressure plate 21, the first bearing 23 disposed between the blade pressure plate 21 and the bearing pressure plate 22, and the fork assembly disposed on the housing 11 for pressing down the bearing pressure plate 22.

[0021] The fork assembly includes a fork 24 and a vertical lead screw 25. The middle part of the fork 24 is rotatably connected to the housing 11 via a connecting pin 26. The first end of the fork 24 abuts against the top surface of the bearing pressure plate 22. The second end of the fork 24 is provided with a vertical threaded hole 27 through which the lead screw 25 passes and is screwed to the lead screw 25. The housing 11 is provided with a vertical hole 28 through which the lead screw 25 passes. The lead screw 25 is rotatably connected to the vertical hole 28 via a second bearing 29. The top end of the lead screw 25 is provided with a handwheel 30 for driving the lead screw 25 to rotate.

[0022] When using the new energy-powered power trowel of this invention, the battery 14 is placed inside the mounting cover 13, providing power to the trowel 10. Turning the handwheel 30 drives the lead screw 25 to rotate around the second bearing 29. The rotation of the lead screw 25 causes the second end of the fork 24 to move upwards. At this time, the first end of the fork 24 rotates downwards around the connecting pin 26, pushing the blade pressure plate 21 and bearing pressure plate 22 downwards. The bearing pressure plate 22 then pushes the carriage bolt 20 downwards, thereby tilting the blade 19 to the desired angle. The starter motor 15 drives the reducer 16 to rotate, which in turn drives the electric crossbar 17 to rotate. The crossbar 17 drives the blade holder 18 and the blade 19 to rotate, thus smoothing the concrete. After the work is completed, the battery 14 can be removed and charged. Alternatively, if the battery 14 is low, it can be replaced to continue working.

[0023] Specifically, the inner wall of the second bearing 29 is fixedly connected to the lead screw 25, and the outer wall of the second bearing 29 is fixedly connected to the inner wall of the vertical hole 28.

[0025] Furthermore, the joystick 12 is a telescopic joystick, and the joystick 12 is equipped with a control switch 33, a speed adjustment knob 34 and a control handle 35.

[0026] In this embodiment, as Figure 4 As shown, the fork 24 includes a first clamping plate 36 and a second clamping plate 37 that are arranged opposite to each other and fixedly connected. A transition block 38 is provided between the second end of the first clamping plate 36 and the second end of the second clamping plate 37, which is rotatably clamped between the first clamping plate 36 and the second clamping plate 37.
