Description

Technical Field

[0001] The utility model relates to a cleaning vehicle with a linkage between a sweeping disc and a suction nozzle, belonging to the technical field of garbage cleaning. Background Art

[0002] During the operation of a cleaning robot, the sweeping disc and the suction nozzle are two important modules, which are related to the quality and effect of cleaning. As the operation time increases, the bristles of the sweeping disc continuously rub against the ground, and the bristles will wear and become shorter. At this time, it is necessary to adjust the sweeping disc separately so that the sweeping disc presses down deeper on the ground for easier brushing. The suction nozzle is usually a cavity surrounded by rubber plates on all sides, and there is a gap of about 1 cm between the bottom end of the rubber plate and the ground.

[0003] The existing sweeping disc and suction nozzle mechanisms are mostly independent modules, and the suction nozzle and the sweeping disc each have a set of driving elements for separately lifting or lowering the suction nozzle and the sweeping disc, which makes the whole structure relatively complex and redundant, and the weight is relatively large.

[0004] An efficient cleaning vehicle disclosed in the Chinese utility model patent with the publication number of CN211547569U includes a vehicle-mounted chassis, a frame is installed on the vehicle-mounted chassis, a water tank and a dustbin are installed on the frame, first sweeping disc assemblies are respectively arranged on both sides of the lower part of the frame near the front of the vehicle, and two groups of second sweeping disc assemblies are arranged at the middle position corresponding to the rear of the first sweeping disc assemblies on the frame. The cleaning width that the cleaning vehicle can achieve is the area between the two groups of first sweeping disc assemblies, and a suction nozzle assembly is arranged at the rear corresponding to the second sweeping disc assemblies on the frame.

[0005] The above reference example conducts ground cleaning by setting a sweeping disc assembly for cleaning and a suction nozzle assembly for adsorption. However, the sweeping disc assembly and the suction nozzle assembly are independently arranged, and only separate lifting can be realized, and linkage lifting cannot be realized. Therefore, a separate lifting mechanism needs to be set, and the structure is complex and redundant. Therefore, improvement is urgently needed. Summary of the Utility Model

[0006] In order to overcome the above-mentioned disadvantages in the prior art, the utility model designs a cleaning vehicle with a linkage between a sweeping disc and a suction nozzle, which can realize the linkage lifting of the sweeping disc and the suction nozzle, and will not interfere with each other during work, simplifies the mechanism, and reduces the cost.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] A cleaning vehicle with a linked sweeping disc and suction nozzle, comprising a vehicle frame, a sweeping disc module and a suction nozzle module. A sweeping disc connecting rod is hinged to the bottom end of the vehicle frame. The sweeping disc module is installed at the free end of the sweeping disc connecting rod. A telescopic driving element is installed at the front end of the vehicle frame, and the telescopic end of the telescopic driving element is hinged to the sweeping disc connecting rod. The suction nozzle module is hinged to the vehicle frame through a connecting rod mechanism, and a flexible connecting piece for driving the suction nozzle module to lift is connected between the suction nozzle module and the sweeping disc connecting rod.

[0009] Further, the connecting rod mechanism includes a front suction nozzle swing arm and a rear suction nozzle swing arm. Both the front suction nozzle swing arm and the rear suction nozzle swing arm are hinged to the suction nozzle module at one end and to the vehicle frame at the other end.

[0010] Further, an extension rod is fixed to the bottom end of the vehicle frame, and the sweeping disc connecting rod is hinged to the extension rod through a sweeping disc rotating pin shaft.

[0011] Further, suction nozzle rotating pin shafts are rotatably connected to both ends of the front suction nozzle swing arm and both ends of the rear suction nozzle swing arm.

[0012] Further, the telescopic driving element is hinged to the middle of the sweeping disc connecting rod.

[0013] Further, the flexible connecting piece is a chain or a steel wire rope.

[0014] Compared with the prior art, the present utility model has the following characteristics and beneficial effects:

[0015] In the present utility model, the sweeping disc module and the suction nozzle module are connected by a chain. The separate adjustment of the sweeping disc module and the natural fall of the suction nozzle module are realized by using the slack state of the chain. At the same time, the tightening of the chain is driven by the lifting of the sweeping disc module, thereby driving the synchronous lifting of the suction nozzle module. And through a single telescopic driving element, the linkage or individual adjustment of the sweeping disc module and the suction nozzle module can be realized, effectively reducing the number of driving elements, simplifying the mechanism, reducing the cost, realizing the linkage lifting, and not interfering with each other during operation.

Detailed implementation manners

[0021] The present utility model will be described in more detail below in conjunction with embodiments.

[0022] As Figures 1 to 4 shown, the road sweeper with interlocked sweeping disk and suction nozzle of this embodiment includes a vehicle frame 8, a sweeping disk module 1 and a suction nozzle module 4. A sweeping disk connecting rod 101 is hinged to the bottom end of the vehicle frame 8, and the sweeping disk module 1 is installed at the free end of the sweeping disk connecting rod 101. A telescopic driving element 7 is installed at the front end of the vehicle frame 8, and the telescopic end of the telescopic driving element 7 is hinged to the sweeping disk connecting rod 101; the suction nozzle module 4 is hinged to the vehicle frame 8 through a link mechanism, and a flexible connecting member 3 for driving the suction nozzle module 4 to lift is connected between the suction nozzle module 4 and the sweeping disk connecting rod 101. In this embodiment, the flexible connecting member 3 is a chain.

[0023] It can be seen from the above description that the beneficial effects of the present utility model are as follows: by connecting the sweeping disk module 1 and the suction nozzle module 4 with a chain, the separate adjustment of the sweeping disk module 1 and the natural falling of the suction nozzle module 4 are realized by using the slack state of the chain. At the same time, the tightening of the chain is driven by the lifting of the sweeping disk module 1, thereby driving the synchronous lifting of the suction nozzle module 4, and the interlock or individual adjustment of the sweeping disk module 1 and the suction nozzle module 4 can be realized by one telescopic driving element 7, effectively reducing the number of driving elements, simplifying the mechanism, reducing the cost, realizing the synchronous lifting, and not interfering with each other during work.

[0024] Furthermore, the link mechanism includes a front swing arm 2 of the suction nozzle and a rear swing arm 5 of the suction nozzle. Both the front swing arm 2 of the suction nozzle and the rear swing arm 5 of the suction nozzle are hinged to the suction nozzle module 4 at one end and hinged to the vehicle frame 8 at the other end.

[0025] It can be seen from the above description that the front swing arm 2 of the suction nozzle, the rear swing arm 5 of the suction nozzle, the vehicle frame 8 and the suction nozzle module 4 enclose a four-bar linkage mechanism, which is convenient for realizing the parallel lifting of the suction nozzle module 4.

[0026] Furthermore, an extension rod 801 is fixed to the bottom end of the vehicle frame 8, and the sweeping disk connecting rod 101 is hinged to the extension rod 801 through a rotating pin shaft 6 of the sweeping disk.

[0027] Furthermore, rotating pin shafts 9 of the suction nozzle are rotatably connected to both ends of the front swing arm 2 of the suction nozzle and both ends of the rear swing arm 5 of the suction nozzle.

[0028] Furthermore, the telescopic driving element 7 is hinged to the middle of the sweeping disk connecting rod 101.

[0029] The working principle of the present utility model is as follows: As Figure 1 shown, when the sweeping disc module 1 is in the lowered state, the chain is in a relaxed state and will not interfere with the suction nozzle module 4. At this time, the suction nozzle module 4 naturally drops by relying on the link mechanism and its own gravity. If the bristles of the sweeping disc module 1 are worn and the sweeping disc module 1 needs to be pressed down for adjustment, the push rod of the telescopic driving element 7 is pushed out, so that the sweeping disc module 1 swings around the sweeping disc rotating pin shaft 6, and the sweeping disc module 1 can be further pressed down, and the whole process will not interfere with the suction nozzle module 4, and the separate downward pressing adjustment of the sweeping disc module 1 can be realized.

[0030] As Figure 2 shown, when the cleaning work is completed and the sweeping disc module 1 needs to be lifted, the push rod of the telescopic driving element 7 retracts, and the sweeping disc module 1 swings upward around the sweeping disc rotating pin shaft 6. The chain changes from the relaxed state to the tense state, and then pulls the suction nozzle module 4 to swing upward around the suction nozzle rotating pin shaft 9, so as to realize the linkage lifting of the sweeping disc module 1 and the suction nozzle module 4 and complete the recycling.

It is only for the convenience of describing the present utility model 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 should not be construed as a limitation to the present utility model.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements.
