[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. This utility model uses a foot pedal axle as the core power drive and a unique transmission gear set to precisely distribute power to each working component. During the cleaning process, the garbage box rises continuously through the operation of the track conveyor mechanism and dumps the garbage into the collection box. There is no need to frequently interrupt the cleaning to dump the garbage, which reduces the frequency of dumping the garbage, ensures the continuity of the cleaning work, improves the overall work efficiency, and also reduces the labor intensity of cleaning personnel to dump the garbage back and forth.

[0028] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0029] As attached Figure 1 Appendix Figure 2 Appendix Figure 3 Appendix Figure 4 Appendix Figure 5 Appendix Figure 6 Appendix Figure 7 and attached Figure 8 As shown:

[0030] Example 1: This utility model provides an outdoor robotic sweeper, comprising:

[0031] The frame 1 has symmetrical mounting slots on its top. A pedal axle bracket 2 is mounted on one side of the bottom of the frame 1. A movable drive flywheel 3 is mounted on the pedal axle bracket 2. An adjustment bracket 17 is movably installed inside the frame 1 above the drive flywheel 3.

[0032] The transmission gear set 6 is mounted on the bottom of the frame 1 on the other side of the pedal axle frame 2. The transmission gear set 6 meshes with the power flywheel 3. The bottom of the frame 1 at the rear end of the transmission gear set 6 is equipped with a first gear 4. The other side of the bottom of the frame 1 is equipped with a wheel frame 15. The first gear 4 and the wheel frame 15 are connected by a chain 5.

[0033] Commutator 8 is installed at the bottom of the frame 1 on one side of the mounting slot. A polyurethane cleaning brush 9 is connected to the bottom of the commutator 8. A driven gear shaft 7 is installed between the commutators 8. A gear plate that meshes with the transmission gear set 6 is installed around the driven gear shaft 7.

[0034] Tracked conveyor 12 is mounted inside the mounting slot. A garbage box 13 is connected around the tracked conveyor 12. A drive roller 11 is installed inside the tracked conveyor 12. A second gear 10 is connected between two opposing drive rollers 11. The second gear 10 is connected to the drive gear set 6. A storage box 14 is installed at the rear end of the top of the frame 1.

[0035] As can be seen from the above, the power of the sweeper originates from the power flywheel 3 mounted on the foot pedal axle 2. When the operator steps on the foot pedal axle 2, the power flywheel 3 rotates accordingly, becoming the power source of the entire sweeper. During the rotation, the power flywheel 3 transmits power to the transmission gear set 6 through meshing with it. As a key power distribution component, the transmission gear set 6 further transmits the power to different working parts after receiving the power. On the one hand, it meshes with the gear plate on the driven gear shaft 7, enabling the driven gear shaft 7 to rotate; on the other hand, it is also connected to the second gear 10, thereby driving the second gear 10 to rotate, providing power support for subsequent sweeping and garbage collection work.

[0036] When the power is transmitted to the driven gear shaft 7 through the transmission gear set 6, the commutator 8 starts to function. The commutator 8 reverses the power transmitted from the driven gear shaft 7 and transmits the power to the polyurethane cleaning brush 9 in a suitable direction and manner, driving the polyurethane cleaning brush 9 to rotate at high speed. The high-speed rotating polyurethane cleaning brush 9 contacts the ground and can effectively sweep up dust, debris and other garbage on the ground, achieving the initial cleaning of the ground.

[0037] After the polyurethane cleaning brush 9 sweeps up the garbage, the second gear 10 rotates under the drive of the transmission gear set 6, which in turn drives the transmission roller 11 connected to it to rotate. The rotation of the transmission roller 11 causes the track conveyor mechanism 12 to start operating. As the track conveyor mechanism 12 rotates, the garbage box 13 also flips and moves continuously. When the garbage box 13 rises to the highest point, the garbage collected inside it begins to be poured into the storage box 14 installed at the rear end of the top of the frame 1 for storage due to gravity. In this way, through the cyclic operation of the track conveyor mechanism 12, the garbage box 13 can continuously collect and dump garbage, achieving efficient garbage treatment.

[0038] When it is necessary to control the movement of the sweeper, the adjusting frame 17 plays a role in pushing the power flywheel 3 to move. When the power flywheel 3 moves to the point where it separates from the transmission gear set 6 and connects with the first gear 4, the power transmission path changes. At this time, the rotational power of the power flywheel 3 is transmitted to the first gear 4. After the first gear 4 rotates, it drives the wheel frame 15 to rotate through the chain 5, thereby realizing the movement of the sweeper. In addition, by controlling the foot pedal frame 2 to drive the power flywheel 3 to rotate forward and backward, the rotation direction of the wheel frame 15 can be further controlled, realizing the forward and backward operation of the sweeper, so that the sweeper can flexibly carry out cleaning operations in different areas.

[0039] As attached Figure 1 Appendix Figure 2 Appendix Figure 3 Appendix Figure 4 Appendix Figure 5 Appendix Figure 6 Appendix Figure 7 and attached Figure 8 As shown:

[0040] Specifically, regarding the aforementioned transmission gear set 6, the transmission gear set 6 includes a gear carrier connected to the bottom of the frame 1, and four meshing transmission gears are rotatably mounted between the gear carriers.

[0041] The gear carrier and the transmission gear are connected by bearings.

[0042] As can be seen from the above, the position of the transmission gear is limited by connecting the bearing bracket to the frame 1, and the transmission gear realizes power transmission under the drive of the power flywheel 3.

[0043] As attached Figure 1 Appendix Figure 2 Appendix Figure 3 Appendix Figure 4 Appendix Figure 5 Appendix Figure 6 Appendix Figure 7 and attached Figure 8 As shown:

[0044] Specifically, regarding the driven gear shaft 7 mentioned above, the driven gear shaft 7 and the second gear 10 are respectively connected to the second and fourth transmission gears from left to right in the transmission gear set 6.

[0045] As can be seen from the above, by connecting with the second and fourth transmission gears from left to right on the transmission gear set 6, the direction of rotation of the driven gear shaft 7 and the second gear 10 can be controlled, thereby providing better power to the commutator 8 and the track conveyor mechanism 12.

[0046] As attached Figure 5 Appendix Figure 6 and attached Figure 7 As shown:

[0047] Specifically, regarding the aforementioned foot pedal axle bracket 2, the axle on the foot pedal axle bracket 2 is a prismatic axle, and the inside of the power flywheel 3 is provided with a prismatic hole that matches the prismatic axle.

[0048] The pedal axle frame 2 also includes two brackets connected to the frame 1. The brackets are located at both ends of the power flywheel 3 and are connected to the pedal axle frame 2 through bearings.

[0049] As can be seen from the above, the use of the prismatic shaft and prismatic hole can prevent the power flywheel 3 from spinning freely around the foot pedal axle bracket 2 during use, thereby improving the transmission effect of the foot pedal axle bracket 2 on the power flywheel 3.

[0050] As attached Figure 1 and attached Figure 2 As shown:

[0051] Specifically, regarding the aforementioned vehicle frame 1, a front wheel 16 is mounted on one side of the vehicle frame 1, and a steering wheel is connected to the top of the front wheel 16 through the vehicle frame 1. A seat is installed on the top of the vehicle frame 1 on the other side of the steering wheel.

[0052] As can be seen from the above, the front wheel 16 and the wheel frame 15 work together to support the device, so as to facilitate ground cleaning. The steering wheel can be used to adjust the angle of the front wheel 16 during driving to control the direction of travel, and the seat can be used to improve the comfort of the device.

[0053] As attached Figure 1 Appendix Figure 3 Appendix Figure 4 Appendix Figure 5 and attached Figure 6 As shown:

[0054] Example 2: This example is basically the same as the previous example, except that:

[0055] A handle 18 is rotatably mounted on the top of the frame 1 above the adjustment frame 17, and an adjustment block sleeved around the adjustment frame 17 is connected to the bottom of the handle 18.

[0056] As can be seen from the above, by adjusting the handle 18, the adjustment block at the bottom drives the adjustment frame 17 to move during the adjustment process, so that the user can adjust the adjustment frame 17 and make the operation more convenient.

Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of this utility model.
