Description

Technical Field

[0001] The present application relates to the technical field of street cleaning, and in particular to a street cleaning vehicle. Background Art

[0002] The small push-type street cleaning vehicle is a convenient and practical cleaning equipment. It is mainly composed of a frame, a handle, a water tank, a cleaning device and other components. It is small in size and flexible in operation. It can be used for cleaning operations in places such as streets by pushing it by hand. It is suitable for narrow areas such as sidewalks, small streets, squares, and places that are difficult for large cleaning vehicles to reach. It is equipped with corresponding cleaning devices, such as high-pressure water guns, nozzles, etc., which can generate water flow with a certain pressure to effectively remove dust, stains, and debris on the ground. It has the advantages of high cleaning efficiency, good effect, and low noise, which can significantly improve the cleanliness of the streets and the quality of environmental sanitation. It is widely used in municipal sanitation, community properties, parks and other places; At present, a Chinese patent with the announcement number "CN117569245A" discloses a street cleaning vehicle, which includes a device capable of spraying water to clean the inclined grooves between floor tiles efficiently and comprehensively, reducing dust, and cleaning the floor tiles more thoroughly. The present invention includes a cart and a mounting plate, etc.; a cart is placed on the floor tiles, a rotatably connected iron cover that can be opened and closed is provided on the cart, and a mounting plate is provided inside the cart. First, the cart is manually pushed onto the floor tiles and the servo motor is started to push the cart, and the brush plate drives the swinging push rod and the reciprocating push rod to rotate, so that the swinging push rod and the reciprocating push rod are constantly in contact with the protrusion, and the brush plate is constantly swinging, and the reciprocating up and down tilting swing of the brush plate can make the bristles on the brush plate clean the inclined grooves between the floor tiles during the movement of the cart, thereby improving the efficiency of street cleaning; However, the above-mentioned small hand-push street cleaning vehicle still has certain defects and shortcomings during actual use. Specifically, the brush plate on the front side of the device is fixedly installed at the bottom of the device, and cannot be positioned during brushing and cleaning. Such a design will obviously cause the brush bar to be unable to completely cover the bottom area of ​​the device, which is likely to cause cleaning dead corners, reducing the comprehensiveness and thoroughness of cleaning. Moreover, during cleaning, the brush plate can only move slightly and cannot move significantly to stably brush the ground, which limits its cleaning effect and efficiency to a certain extent. At the same time, the bottom of the brush plate of the device cannot be sprayed with water during brushing, which makes it easy to have water spraying and brushing dead corners during water spraying and brushing cleaning, and cannot achieve all-round cleaning. In summary, this small hand-push street cleaning vehicle has certain defects and shortcomings during use, and therefore it is urgently needed to be improved. Summary of the invention

[0023] The implementation principle of a street cleaning vehicle in the embodiment of the present application is as follows: by setting a water storage mechanism 3, a driving mechanism 7 and a first cleaning mechanism 5 to cooperate with each other, the device can be operated by starting the driving motor 72 in actual use. The driving motor 72 can drive the first synchronous wheel 73 to rotate, that is, drive the first gear 52 at the bottom to rotate. It is worth noting that the first gear 52 and the toothed ring 54 at the bottom of the inner slip ring 53 of the annular rail 51 are in a meshing connection state. When the first gear 52 rotates, the toothed ring 54 can be driven to rotate, and the rotation of the toothed ring 54 can assist in driving the brush plate 55 to rotate. In this process, the brush plate 55 is closely attached to the ground, and the brush plate 55 is driven by the rotation of the toothed ring 54. The device can be moved by pushing the vehicle body and rolling on the ground with the assistance of the universal wheels 8 during use, so as to clean the ground by brushing. Meanwhile, during the cleaning process, the water pump 32 can be started to pump the water in the water tank 31 and transport it to the atomizing nozzle 36 through the main pipe 35. The water is sprayed from the inside to the outside through the atomizing nozzle 36, which can effectively avoid a large amount of dust during cleaning. At the same time, the inner side of the brush plate 55 can be sprayed with water and brushed. In general, this design can have a more efficient cleaning efficiency, greatly improve the overall cleaning comprehensiveness of the device, and effectively avoid the occurrence of cleaning dead corners. By setting the second cleaning mechanism 6, the device can be used to start the driving motor 72 to drive the first synchronous wheel 73 to rotate. After the first synchronous wheel 73 rotates, the second synchronous wheel 75 is driven to rotate through the synchronous belt 74. At this time, the second synchronous wheel 75 at the other end can be driven to rotate. The rotation of the second synchronous wheel 75 can drive the half gear 62 at its bottom to rotate. The half gear 62 and the first rack 65 are in a meshing connection state. The rotation of the half gear 62 can drive the movable frame 64 to slide toward one side. After the half gear 62 rotates one circle, it will be meshed and connected with another first rack 65. At this time, the half gear 62 and the other first rack 65 are meshed and connected, and then the movable frame 64 can be driven to slide toward the other side. In this way, during the cleaning process, when the driving motor 72 drives the brush plate 55 to rotate, the movable frame 64 can be synchronously driven to drive the two brush discs 664 to slide back and forth left and right. During the cleaning process, the top of the brush plate 55 is driven by the circular plate 661 The second gear 663 is displaced, and the second gear 663 is meshed with the second rack 662. During the linear displacement of the second gear 663, the second rack 662 can drive the second gear 663 to rotate. The rotation of the second gear 663 can drive the brush plate 664 at the bottom to rotate, and the brush plate 664 rotates itself during the left and right displacement process, which can more efficiently brush and clean the ground. This can not only improve the cleaning effect of the device on the ground, effectively avoid cleaning dead corners, but also further improve its efficiency in brushing and cleaning the ground. In addition, the setting of the left and right displacement of the first cleaning mechanism 5 can more comprehensively clean the ground covered by the bottom of the bottom base 1. At the same time, the setting of its driving mechanism 7 can adaptively drive the first cleaning mechanism 5 and the second cleaning mechanism 6 to clean in conjunction. On the whole, the ground can be cleaned more efficiently and energy-savingly, without the need to use multiple motors to assist in cleaning, which greatly reduces the overall cost of use.

[0024] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
