TECHNICAL FIELD
[0001] The utility model belongs to the technical field of cleaning vehicle accessories, and particularly relates to a protective structure of an exhaust pipe of a washing and sweeping vehicle. BACKGROUND
[0002] With the development of science and technology, various trades are gradually automated, which is not only high in efficiency but also can save a large amount of labor cost. The environmental sanitation work is an important part of city management, and with the popularization of washing and sweeping vehicles, a large number of workers are no longer needed to participate in cleaning. The existing washing and sweeping vehicle structure mainly adopts washing and sweeping discs arranged on both sides of the vehicle, the washing and sweeping discs can clean the road surface and sweep the garbage to the bottom of the vehicle, and then the dust suction mechanism is used to suck the garbage into the garbage can. The exhaust pipe is one of the essential components of the washing and sweeping vehicle, and is usually extended from the bottom of the vehicle to the rear. However, due to the limitation of the structure of the vehicle, the garbage in the rotating process of the washing and sweeping disc often collides with or sticks to the exhaust pipe. If the collision lasts for a long time, the exhaust pipe may be deformed or even leak. If the garbage sticks to the exhaust pipe, the high-temperature exhaust gas discharged from the exhaust pipe may ignite the garbage. In particular, in the environment with high temperature in summer, dry branches and leaves are easy to be ignited. Once ignited, the vehicle will be damaged, and even the safety of the driver will be threatened.
[0003] In view of the above, it is necessary to design a protective structure of an exhaust pipe of a washing and sweeping vehicle, which is simple in structure, low in cost and can effectively prevent the garbage from contacting the exhaust pipe. For this purpose, the applicant has made a beneficial design, and the technical scheme to be introduced below is generated in this background. CONTENT OF THE UTILITY MODEL

DETAILED DESCRIPTION
[0016] The specific embodiments of the utility model are described in detail below in combination with the drawings, but the description of the embodiments is not the limitation of the technical scheme, and any change in form but not in substance according to the concept of the utility model should be regarded as the protection scope of the utility model.
[0017] In the following description, the directional or positional concepts of up, down, left, right, front and back are all based on the position shown in the drawings, so they cannot be understood as the special limitation of the technical scheme provided by the utility model. Figure 1
[0018] Please refer to Figure 1 、 Figure 2 The utility model relates to a kind of protective structures of washing and sweeping vehicle exhaust pipe, including a vehicle beam 1, an exhaust pipe 2 being installed below vehicle beam 1 and a washing and sweeping device 3 being installed in one side of vehicle beam 1.
[0019] As the technical innovation point of the utility model is: the aforementioned vehicle beam 1 is detachably installed with a blocking plate 4, the aforementioned blocking plate 4 is located at the position between exhaust pipe 2 and washing and sweeping device 3, the upper edge of the aforementioned blocking plate 4 is connected with at least one mounting frame 41 fixed with vehicle beam 1, one end of the aforementioned mounting frame 41 is configured as detachable connection with vehicle beam 1, and the other end is configured as detachable connection with the upper edge of blocking plate 4.In the embodiment, the number of the aforementioned mounting frame 41 is a pair, the upper end of a pair of the aforementioned mounting frame 41 is fixed with vehicle beam 1 through a mounting frame fixing screw 42 respectively, the lower end of a pair of the aforementioned mounting frame 41 is respectively folded to one side of exhaust pipe 2 with an extension plate 411, the end of the aforementioned extension plate 411 is again folded downward with a blocking fixed plate 412, and the aforementioned blocking fixed plate 412 is fixed with blocking plate 4 through a blocking plate fixing screw 43.
[0020] Please refer to Figure 1 The exhaust pipe 2 is connected to the engine of the vehicle at one end for leading out the high temperature exhaust gas and is free at the other end for leading out the exhaust gas. A plurality of exhaust pipe clamps 21 are arranged at intervals along the length of the exhaust pipe 2 and are fixed to the bottom of the vehicle beam 1 by clamp fixing screws 211. The barrier plate 4 is made of stainless steel and is longer than the length of the exhaust pipe 2. The barrier plate 4 is arranged close to one side of the exhaust pipe 2 and away from the washing and sweeping device 3 and is arranged vertically to the horizontal base surface.
[0021] Further, the washing and sweeping device 3 comprises a main support 31 fixed to one side of the vehicle beam 1, a rotating frame 32 hingedly connected to the main support 31, a washing and sweeping disc mounting frame 33, a connecting beam 34 hingedly connected to the rotating frame 32 and the washing and sweeping disc mounting frame 33 at two ends respectively, a balance bar 35 hingedly connected to the rotating frame 32 and the washing and sweeping disc mounting frame 33 at two ends respectively, a driving motor 36 mounted on the washing and sweeping disc mounting frame 33 and a washing and sweeping disc 37 arranged below the washing and sweeping disc mounting frame 33 and drivingly connected to the driving motor 36. The rotating frame 32, the washing and sweeping disc mounting frame 33, the connecting beam 34 and the balance bar 35 form a four-bar linkage structure to ensure that the washing and sweeping disc mounting frame 33 keeps the washing and sweeping disc 37 in contact with the ground during the up and down displacement. The main support 31 is hingedly connected to the rotating frame 32 by a main support shaft 311 to enable the rotating frame 32 to rotate the washing and sweeping disc mounting frame 33, the connecting beam 34, the balance bar 35, the driving motor 36 and the washing and sweeping disc 37 together towards the vehicle beam 1.
[0022] Please continue to refer to Figure 1 and Figure 2In actual use, a cylinder (not shown in the figure) is connected to the connecting beam 34, which drags the connecting beam 34 to rotate around the main support 31. When the cylinder is pushed out, the connecting beam 34 and the rotating frame 32 rotate around the main support shaft 311, so that the washing and sweeping disc 37 extends to the outside of the vehicle away from the vehicle beam 1. At the same time, with the pushing of the cylinder, one end of the connecting beam 34 rotates downward around the rotating frame 32. The washing and sweeping disc 37 always keeps a downward state under the four-link structure formed by the rotating frame 32, the washing and sweeping disc mounting frame 33, the connecting beam 34 and the balance bar 35. When the cylinder extends to the limit position, the washing and sweeping disc 37 is in full contact with the ground. The driving motor 36 works to rotate the washing and sweeping disc 37 to realize the cleaning work on the ground. In the working process, the blocking plate 4 is away from the washing and sweeping disc 37 and does not affect the cleaning work. The garbage thrown out by the washing and sweeping disc 37 can be blocked by the blocking plate 4, and the garbage can be stably entered into the bottom of the vehicle beam 1 to be sucked away by the dust suction device. When the cleaning work is completed, the cylinder is retracted, so that the washing and sweeping disc 37 is lifted upward and rotates around the main support shaft 311 to rotate close to the vehicle beam 1. When the cylinder is retracted to the limit position, the washing and sweeping disc 37 is separated from the ground and is attached to the vehicle beam 1, so that the washing and sweeping disc 37 does not affect the normal driving of the vehicle.
[0023] In summary, the technical scheme provided by the utility model makes up for the defects in the prior art, successfully completes the invention task, and truly realizes the technical effects described in the technical effect column above.
