In this embodiment, the objects to be cleaned are garbage such as leaves.

[0035] When it is necessary to clean the leaves on the road, start the leaf suction machine with double suction ports, drive the impeller 310 to rotate, and generate suction to transport the objects to be cleaned near the suction port 331 to the dust bag 200 through the leaf suction head 330 and the connecting pipe 320, thereby completing the cleaning of the road. In addition, when it is necessary to clean the corners of the road and other locations that are difficult to clean, connect the auxiliary suction pipe 400 to the leaf suction head 330, and then align the auxiliary suction pipe 400 with the area to be cleaned, thereby completing the cleaning of the corners of the road and other locations that are difficult to clean, thereby increasing the range of leaf suction, and making the leaf suction machine with double suction ports more widely applicable. Furthermore, the present application is provided with two leaf suction assemblies 300, thereby improving the efficiency of leaf suction through the two leaf suction heads 330, reducing the operation time of the leaf suction operator, and improving work efficiency.

[0036] In this embodiment, the auxiliary suction pipe 400 is a hose, so that the auxiliary suction pipe 400 can be bent, so that the auxiliary suction pipe 400 is easy to align with the area that needs to be cleaned, making the use of the auxiliary suction pipe 400 more convenient.

[0037] In this embodiment, the number of the auxiliary suction pipe 400 is one. When it is necessary to clean the corners on the left side of the road, the auxiliary suction pipe 400 is connected to the leaf suction head 330 on the left side, and then the corners on the left side of the road are cleaned through the auxiliary suction pipe 400; when it is necessary to clean the corners on the left side of the road, the auxiliary suction pipe 400 is removed from the leaf suction head 330 on the left side and connected to the leaf suction head 330 on the right side, and then the corners on the right side of the road are cleaned through the auxiliary suction pipe 400. Only one auxiliary suction pipe 400 is used, which can save structure and cost. In other embodiments, the number of the auxiliary suction pipes 400 is two, one auxiliary suction pipe 400 is connected to the leaf suction head 330 on the left side, and the other auxiliary suction pipe 400 is connected to the leaf suction head 330 on the right side, so that the auxiliary suction pipe 400 does not need to be repeatedly disassembled.

[0038] refer to Figure 1The leaf suction machine with double suction ports also includes two switching switches 500, and the two switching switches 500 correspond to the two leaf suction heads 330 one by one. Each switching switch 500 is set on a corresponding leaf suction head 330, and the switching switch 500 has a main suction state and an auxiliary suction state. When the switching switch 500 is in the main suction state, the switching switch 500 blocks the auxiliary suction pipe 400, and the connecting pipe 320 is connected to the leaf suction head 330; when the switching switch 500 is in the auxiliary suction state, the switching switch 500 blocks the leaf suction head 330, and the connecting pipe 320 is connected to the auxiliary suction pipe 400.

[0039] refer to Figure 4 and Figure 5 The leaf suction head 330 has a leaf suction channel 332, which is connected to the connecting pipe 320, and the suction port 331 is connected to the leaf suction channel 332. The side wall of the leaf suction head 330 is provided with an auxiliary suction port 333 connected to the leaf suction channel 332, and the auxiliary suction port 333 is used to communicate with the auxiliary suction pipe 400. When the switching switch 500 is in the main suction state, the switching switch 500 blocks the auxiliary suction port 333 to block the auxiliary suction pipe 400, and the connecting pipe 320 is connected to the leaf suction head 330; when the switching switch 500 is in the auxiliary suction state, the switching switch 500 blocks the leaf suction channel 332, and the connecting pipe 320 is connected to the auxiliary suction pipe 400.

[0040] Specifically, when the switching switch 500 is in the main suction state, the road is cleaned through the leaf suction head 330. At this time, the switching switch 500 blocks the auxiliary suction port 333, so that the auxiliary suction pipe 400 is no longer connected to the leaf suction head 330. Therefore, the auxiliary suction pipe 400 cannot perform the leaf suction work, but at this time, the leaf suction channel 332 of the leaf suction head 330 and the connecting pipe 320 drive the impeller 310 in the connecting pipe 320 to rotate, which can generate suction to transport the objects to be cleaned near the suction port 331 through the leaf suction channel 332 and the connecting pipe 320 to the dust collecting bag 200. When the switching switch 500 is in the auxiliary suction state, the road corners are cleaned through the auxiliary suction pipe 400. At this time, the switching switch 500 blocks the leaf suction channel 332, so that the suction port 331 of the leaf suction head 330 is no longer connected with the connecting pipe 320. Therefore, the leaf suction head 330 can no longer perform the leaf suction work, but at this time, the auxiliary suction pipe 400 is connected with the connecting pipe 320 through the auxiliary suction port 333, thereby driving the impeller 310 in the connecting pipe 320 to rotate, which can generate suction to transport the objects to be cleaned near the auxiliary suction pipe 400 through the auxiliary suction pipe 400, the auxiliary suction port 333 and the connecting pipe 320 to the dust collecting bag 200.

[0041] refer to Figure 2 and Figure 5The switch 500 includes a baffle 510, a rotating shaft 520 and a gripping member 530. The rotating shaft 520 passes through the leaf suction head 330. One side of the baffle 510 is fixedly sleeved on the rotating shaft 520, and the baffle 510 is located in the leaf suction head 330. The gripping member 530 is fixedly connected to one or both ends of the rotating shaft 520 exposed to the leaf suction head 330. Rotating the gripping member 530 can drive the rotating shaft 520 and the baffle 510 to rotate, so that the baffle blocks the auxiliary suction port 333 or blocks the leaf suction channel 332. In this embodiment, the gripping member 530 is fixedly connected to both ends of the rotating shaft 520 at the same time, so that the connection of the gripping member 530 is more reliable.

[0042] Specifically, when the holding piece 530 is rotated to drive the rotating shaft 520 and the baffle 510 to rotate so that the baffle blocks the auxiliary suction port 333, the switching switch 500 is in the main suction state; when the holding piece 530 is rotated to drive the rotating shaft 520 and the baffle 510 to rotate so that the baffle blocks the suction leaf channel 332, the switching switch 500 is in the auxiliary suction state.

[0043] refer to Figure 2 and Figure 5 The switch 500 further includes a locking member 540, which is used to lock the holding member 530 relative to the leaf suction head 330, thereby locking the position of the baffle.

[0044] refer to Figure 2 and Figure 5 The switch 500 further includes a connecting piece 550 , which is fixedly connected to the holding piece 530 . The locking piece 540 can pass through the connecting piece 550 and be inserted into the side wall of the leaf suction head 330 , thereby pressing the connecting piece 550 against the side wall of the leaf suction head 330 .

[0045] refer to Figure 1 The leaf suction machine with double suction ports further comprises a driving member 600, and the driving member 600 is used to drive the impeller 310 to rotate. In this embodiment, the driving member 600 is an engine or a motor.

[0046] refer to Figure 1 and Figure 6, the number of the driving member 600 is one, and the driving member 600 drives the two impellers 310 to rotate simultaneously through two belts; specifically, the driving member 600 is connected with a first transmission shaft 610, and the impeller 310 is fixedly sleeved on the second transmission shaft 311. The first transmission shaft 610 and the second transmission shaft 311 are connected through belt transmission, so that the driving member 600 can drive the impeller 310 to rotate through the first transmission shaft 610, the belt and the second transmission shaft 311, wherein the number of the second transmission shaft 311 and the belt are both two, and the two second transmission shafts 311 and the two belts correspond to the impeller 310 one by one. The belt is not shown in the attached drawings, but the belt used is a common belt in the prior art, which can realize the transmission connection between the first transmission shaft 610 and the second transmission shaft 311.

[0047] In other embodiments, the number of driving members 600 is two, and the two driving members 600 correspond to the two impellers 310 one by one. The driving member 600 is directly connected to the corresponding impeller 310 to drive the corresponding impeller 310 to rotate, or the driving member 600 is connected to the corresponding impeller 310 through a belt to drive the corresponding impeller 310 to rotate.

[0048] refer to Figure 1 The double suction port leaf suction machine also includes an operating rod 700, which is connected to the auxiliary suction pipe 400. It is more convenient to move the auxiliary suction pipe 400 through the operating rod 700, and there is no need to directly hold the suction pipe by hand. Specifically, the operating rod 700 is connected to the end of the auxiliary suction pipe 400 away from the leaf suction head 330, that is, the operating rod 700 is connected to the suction port end of the auxiliary suction pipe 400.

[0049] refer to Figure 1 and Figure 3 The leaf suction machine with double suction ports also includes a fixing member 800 for fixing the operating rod 700. Specifically, when the auxiliary suction pipe 400 is not in use, the operating rod 700 is fixed, so that the auxiliary suction pipe 400 is also fixed together, thereby preventing the auxiliary suction pipe 400 from falling or causing interference. In this embodiment, the fixing member 800 is used to fix the operating rod 700 on the connecting pipe 320.

[0050] refer to Figure 1 and Figure 4 The dust bag 200 has mesh holes 210 on its side, and the air in the dust bag 200 can be discharged through the mesh holes 210. Specifically, when the leaves waiting to be cleaned are transported into the dust bag 200, the air will also be sucked into the dust bag 200. The mesh holes 210 are provided so that the excess air in the dust bag 200 can escape, but the leaves waiting to be cleaned are still retained in the dust bag 200, so as to prevent the dust bag 200 from being burst by the air.

[0051] refer to Figure 1A protective cover 900 is provided on the side of the dust bag 200, and the protective cover 900 covers the mesh 210. A vent 910 is provided at the bottom of the protective cover 900, and the air in the dust bag 200 can be discharged through the mesh 210 and the vent 910. Specifically, the provision of the protective cover 900, on the one hand, plays a role in protecting the mesh 210 to prevent external objects from scratching the mesh 210, and on the other hand, the vent 910 of the protective cover 900 faces downward, thereby preventing the air in the dust bag 200 from blowing to pedestrians.

[0052] In this embodiment, mesh holes 210 are provided on two opposite sides of the dust bag 200, and there are two protective covers 900. The two protective covers 900 are arranged on two opposite sides of the dust bag 200, and the two protective covers 900 cover the mesh holes 210 on the two side edges of the dust bag 200 respectively.

[0053] refer to Figure 1 The machine body 100 includes a frame 110, a first rotating wheel 120 and a second rotating wheel 130. The dust bag 200 is arranged at the rear of the frame 110.

The lifting assembly 1000 can be lifted and lowered along its own axis to adjust the distance between the first rotating wheel 120 and the frame 110, thereby adjusting the height of the leaf suction head 330. Specifically, when the lifting assembly 1000 rises along its own axis so that the distance between the first rotating wheel 120 and the frame 110 is farther, since the first rotating wheel 120 touches the ground, the height of the frame 110 and the leaf suction head 330 becomes higher, thereby avoiding the situation where the leaf suction head 330 contacts and rubs against the ground on uneven roads.

[0055] refer to Figure 1 and Figure 6 The lifting assembly 1000 includes a first pipe fitting 1010 and a second pipe fitting 1020 which are sleeved and connected. The first pipe fitting 1010 is arranged at the front of the frame 110, and the first rotating wheel 120 is rotatably arranged at the bottom of the second pipe fitting 1020. The second pipe fitting 1020 can be lifted and lowered relative to the first pipe fitting 1010 along its own axial direction, thereby adjusting the distance between the first rotating wheel 120 and the frame 110, and then adjusting the height of the suction leaf head 330.

[0056] In this embodiment, the number of the lifting assemblies 1000 is two, which correspond one to one with the two first rotating wheels 120 , and the corresponding relationship is the same as described above.

[0057] refer to Figure 1 The leaf sucking machine with double suction ports also includes a connecting member 1100, which is fixedly connected to the front of the frame 110. The connecting member 1100 is used to connect to a traction device, so that the leaf sucking machine with double suction ports can be driven to move by the traction device.

[0058] In this embodiment, the connector 1100 has different models to adapt to different types of towing equipment. Specifically, the connector 1100 can be connected to a logistics trailer or a ball head device.
