DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0021] In the description of the embodiments of the present application, it should be noted that the terms "upper", "lower", "left", "right", "inside", "outside", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, which is only for the convenience of describing the embodiments of the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application. The terms "first", "second", and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance. In addition, the terms "installation" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, or it can be a connection between the two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0022] During the cleaning process, the industrial vacuum cleaner heads face the ground and maintain a proper distance from the ground to suck the waste, dust, etc. on the ground into the collection tube. However, the suction power of the vacuum cleaner heads is limited, and some waste adhering to the ground may be difficult to be cleaned by the industrial vacuum cleaner, resulting in the cleaning effect being less than expected.

[0023] In view of the above reasons, an embodiment of the present application provides a suction and sweeping device, which can effectively peel and collect waste from the ground, has a good cleaning effect, and solves the technical problem in the prior art that the cleaning effect is not as good as expected.

[0024] like Figures 1 to 5 As shown, the suction and sweeping device provided in the embodiment of the present application includes a bracket 1, a fixing mechanism 2 and a cleaning mechanism 3. The cleaning mechanism 3 includes a first motor 31, a first transmission assembly 32 and a cleaning wheel 33.

[0025] The fixing mechanism 2 is mounted on the bracket 1 and is used to fix the dust collector head 9. The first transmission assembly 32 is mounted on the bracket 1, and its input end is connected to the rotating shaft of the first motor 31. Both ends of the cleaning wheel 33 are rotatably connected to the bracket 1 and are in transmission connection with the output end of the first transmission assembly 32, and are configured to rotate in the direction of the fixing mechanism 2 to clean the ground.

[0026] For example, Figure 2 and Figure 3 As shown, two bearing seats are provided on the bracket 1, and bearings are installed at both axial ends of the cleaning wheel 33, and the two bearings are respectively installed on the bearing seats, thereby realizing that both ends of the cleaning wheel 33 are rotatably connected to the bracket 1.

[0027] When the vacuum sweeping device provided in the embodiment of the present application is working, the first motor 31 transmits power to the cleaning wheel 33 through the first transmission assembly 32; the cleaning wheel 33 rotates on the bracket 1 to clean the ground, especially the waste adhered to the ground, and the cleaning wheel 33 cleans the waste to the position of the fixing mechanism 2, and the dust suction head 9 fixed on the fixing mechanism sucks the waste and dust swept by the cleaning wheel 33 into the collection barrel.

[0028] The cleaning wheel 33 in the embodiment of the present application effectively peels off the waste from the ground and pushes it to the location of the dust head 9, so that the suction and sweeping device has a better cleaning effect, solving the technical problem in the prior art that the cleaning effect is not as good as expected.

[0029] like Figure 1 and Figure 2 As shown, the cleaning wheel 33 in the embodiment of the present application is located in front of the fixing mechanism 2 in the moving direction.

[0030] When the suction and sweeping device moves forward driven by the traveling vehicle 10, the cleaning wheel 33 first contacts the waste and dust on the ground, and sweeps the waste and dust to the vicinity of the fixing mechanism 2, and the dust suction head 9 cleans the waste and dust, so that the suction and sweeping device has a better cleaning effect.

[0031] In other embodiments of the present application, the cleaning wheel 33 may also be arranged at the rear of the moving direction of the fixing mechanism 2. When the suction and sweeping device moves forward driven by the traveling vehicle 10, the dust collecting head 9 first cleans the waste and dust on the ground, and the waste and dust remaining on the ground are cleaned by the cleaning wheel 33 at the rear in the direction of the fixing mechanism 2, and then the dust collecting head 9 cleans the remaining waste and dust again.

[0032] Reference Figures 2 to 4 The first transmission assembly 32 includes a first reducer 321 , a first transmission wheel 322 and a second transmission wheel 323 .

[0033] The first reducer 321 is mounted on the bracket 1, and the input shaft of the reducer is connected to the rotating shaft of the first motor 31. The first transmission wheel 322 is mounted on the output shaft of the first reducer 321. The first motor 31 has a high output speed, and the first reducer 321 is used to reduce the power of the first motor 31 and transmit the reduced power to the first transmission wheel 322.

[0034] Exemplarily, the first reducer 321 is connected to the bracket 1 by bolts and nuts. Of course, the first reducer 321 can also be connected to the bracket 1 by welding, riveting, etc.

[0035] The second transmission wheel 323 is mounted on the shaft end of the cleaning wheel 33 and is in transmission connection with the first transmission wheel 322. The first transmission wheel 322 transmits power to the second transmission wheel 323, so that the second transmission wheel 323 drives the cleaning wheel 33 to rotate, thereby cleaning the ground.

[0036] Exemplarily, the first transmission wheel 322 and the second transmission wheel 323 can both be pulleys, and the belt 324 is wound around the first transmission wheel 322 and the second transmission wheel 323, so that the power of the first transmission wheel 322 is transmitted to the second transmission wheel 323 through the belt 324. Of course, the first transmission wheel 322 and the second transmission wheel 323 are not limited to pulleys, for example: the first transmission wheel 322 and the second transmission wheel 323 can also be sprockets, and chains are installed on the first transmission wheel 322 and the second transmission wheel 323, and the power of the first transmission wheel 322 is transmitted to the second transmission wheel 323 through the chain.

[0037] It should be noted that the specific structure of the first transmission assembly 32 is not limited to Figures 1 to 4 The structure shown is a limitation. In other embodiments of the present application, the first transmission assembly 32 may also be in other structural forms.

[0038] For example, the first transmission assembly 32 includes a first gear and a second gear, the first gear is installed on the rotating shaft of the first motor 31, the second gear is installed on the end of the cleaning wheel 33, the first gear is meshed with the second gear, and the number of teeth of the first gear is less than the number of teeth of the second gear.

[0039] The embodiment of the present application provides a specific structure of the fixing mechanism 2. Figure 1 and Figure 2 As shown, the fixing mechanism 2 includes a swinging member 21 and a driving mechanism 22. The swinging member 21 is provided with a slot 211, which is rotatably connected to the bracket 1 and forms a first rotation axis 6. The driving mechanism 22 is mounted on the bracket 1, and the output end of the driving mechanism 22 is connected to the swinging member 21, and is configured to drive the swinging member 21 to swing back and forth around the first rotation axis 6. The first rotation axis 6 is parallel to the ground and perpendicular to the moving direction of the bracket 1.

[0040] When the fixing mechanism 2 is working, the output end of the driving mechanism 22 drives the swinging member 21 to swing back and forth around the first rotation axis 6, and the dust head 9 installed on the swinging member 21 swings with the swinging member 21, and the direction of the dust head 9 reciprocates in the direction perpendicular to the ground and the forward direction of the fixing mechanism 2. When encountering large-sized waste, the dust head 9 installed on the swinging member 21 can suck in the waste when it swings to an angle, thereby preventing the large-sized waste from hindering the forward movement of the suction and sweeping device.

[0041] Further, continue to refer to Figure 1 and Figure 2The driving mechanism 22 includes a second motor 221, a second transmission assembly 222 and a connecting rod 223. The second transmission assembly 222 is mounted on the bracket 1, the input end of the second transmission assembly 222 is connected to the rotating shaft of the second motor 221, and the output end of the second transmission assembly 222 is connected to one end of the connecting rod 223 to drive the connecting rod 223 to reciprocate in its length direction. The end of the connecting rod 223 away from the second transmission assembly 222 is rotatably connected to the swing member 21, and forms a second rotation axis 7.

[0042] The rotating shaft of the second motor 221 transmits power to the input end of the second transmission assembly 222. The second transmission assembly 222 is used to convert the rotational motion of the second motor 221 into power to drive the connecting rod 223, and drive the connecting rod 223 to reciprocate in its own length direction through the output end. When the connecting rod 223 reciprocates in its own length direction, it drives the swing member 21 to swing around the first rotation axis 6.

[0043] The second transmission assembly 222 includes a second reducer 2221 and a turntable 2222. The second reducer 2221 is mounted on the bracket 1, and the input shaft of the second reducer 2221 is connected to the rotating shaft of the motor. The rotating shaft speed of the second motor 221 is relatively high, and the second reducer 2221 is used to reduce the power of the second motor 221 and transmit the reduced power to the turntable 2222. The turntable 2222 is coaxially mounted on the output shaft of the second reducer 2221, and the turntable 2222 rotates coaxially with the output end of the second reducer 2221.

[0044] The end of the connecting rod 223 away from the swing member 21 is eccentrically and rotationally connected to the rotating disk 2222. Specifically, the connecting rod 223 and the rotating disk 2222 are rotationally connected to form a third rotation axis 8, and the third rotation axis 8 is parallel to the rotation axis of the rotating disk 2222. When the rotating disk 2222 rotates, the end of the connecting rod 223 away from the swing member 21 rotates around the third rotation axis 8 and moves in the height direction. In this way, the connecting rod 223 can drive the swing member 212 to swing around the first rotation axis 64.

[0045] Exemplarily, the second reducer 2221 is connected to the bracket 1 through bolts and nuts. Of course, the second reducer 2221 can also be connected to the bracket 1 through welding, riveting, etc.

[0046] When the suction and sweeping device is working, the sweeping wheel 33 sweeps the ground, causing some dust on the ground to float up, in order to prevent excessive diffusion of dust and cause air pollution. The suction and sweeping device provided in the embodiment of the present application also includes a spray mechanism 4, such as Figure 5 shown.

[0047] The spray mechanism 4 is disposed above the bracket 1 and is configured to spray the bracket 1. When the suction and sweeping device provided in the embodiment of the present application is working, the spray mechanism 4 sprays mist water vapor to the bracket 1, so that the floating dust combines with the water droplets and falls down, thereby preventing dust from polluting the air.

[0048] The embodiment of the present application provides a specific structure of the spray mechanism 4. Figure 5 The spray mechanism 4 includes a water tank 41, a water pump and a spray pipe 42. The input end of the water pump is connected to the inner cavity of the water tank 41, and the output end of the water pump is connected to the spray pipe 42. The spray pipe 42 is arranged above the bracket 1.

[0049] The water pump is used to pump the water in the water tank 41 to the spray pipe 42, so that the water in the water tank 41 is sprayed out from the spray pipe 42 to form mist. Figure 5 In the embodiment, the water pump is installed in the water tank 41. Of course, the water pump can also be installed outside the water tank 41.

[0050] like Figure 3 and Figure 5 As shown, the vacuum sweeping device provided in the embodiment of the present application further includes a folding mechanism 5. The two ends of the folding mechanism 5 are respectively connected to the bracket 1 and the traveling vehicle 10, and are configured to fold the bracket 1 toward the traveling vehicle 10.

[0051] When the suction sweeping device needs to work, the folding mechanism 5 unfolds the suction sweeping device from the traveling vehicle 10, so that the suction sweeping device is close to the ground, and then the suction sweeping device cleans the ground. When the suction sweeping device is finished working, the folding mechanism 5 folds the suction sweeping device toward the traveling vehicle 10, reducing the space occupied by the suction sweeping device.

[0052] This application provides a specific structure of the folding mechanism 5. Figure 3 and Figure 5 The folding mechanism 5 includes a telescopic member 51 and a rotating member 52. The two ends of the telescopic member 51 are respectively rotatably connected to the bracket 1 and the traveling vehicle 10. The rotating member 52 is arranged on the bracket 1 and is rotatably connected to the traveling vehicle 10.

[0053] The telescopic member 51 is telescopic to rotate the suction and sweeping device relative to the traveling vehicle 10, thereby folding the suction and sweeping device toward the traveling vehicle 10 or unfolding the suction and sweeping device from the traveling vehicle 10. For example, the telescopic member 51 may be a hydraulic cylinder, a pneumatic cylinder, or the like.

[0054] The various embodiments in this specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referenced to each other. Each embodiment focuses on the differences from other embodiments.

[0055] The above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit the present application. Although the present application has been described in detail with reference to the aforementioned embodiments, a person of ordinary skill in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some or all of the technical features thereof may be replaced by equivalents.
