[0021] The utility model provides a road sweeper sewage automatic discharge structure, including recycling box bracket 1 and recycling box 2, recycling box 2 is installed on recycling box bracket 1, and the bottom of recycling box 2 is connected with detachable sewage discharge pipe 3, is provided with ball valve 4 on sewage discharge pipe 3, and electric push rod 5 is installed at the bottom of recycling box 2, and the telescopic end of electric push rod 5 is installed with connecting piece 6, and connecting piece 6 is connected with the valve stem of ball valve 4.

[0022] Specifically, the sewage discharge pipe 3 includes a first sewage pipe 31 and a second sewage pipe 32. The first sewage pipe 31 is installed at the bottom of the recycling box 2, and the second sewage pipe 32 is installed on the recycling box bracket 1.

[0023] From the above description, it can be seen that when the recycling box is turned over, the first sewage pipe and the second sewage pipe can be separated, thereby avoiding the influence of the sewage pipe on the operation of the road sweeper.

[0024] Specifically, the second sewage pipe 32 is installed with a drainage conical bowl 33 at one end close to the first sewage pipe 31, and the first sewage pipe 31 is provided with a rubber sealing pad 34 at one end away from the recycling box 2, which cooperates with the inner wall of the drainage conical bowl 33.

[0025] From the above description, it can be seen that through the cooperation of the drainage conical bowl and the rubber sealing pad, an elastic sealing cooperation can be formed between the first sewage pipe and the second sewage pipe, so as to ensure stable sealing even if there is an error between the box body, the box bracket and the drainage components.

[0026] Specifically, the recycling box bracket 1 is installed with a mounting bracket 11 cooperating with the drainage conical bowl 33 through bolts, and the top of the drainage conical bowl 33 is provided with a mounting flange 35, and the drainage conical bowl 33 is installed on the mounting bracket 11 through the mounting flange 35.

[0027] Specifically, the second sewage pipe 32 is a bent pipe, and the angle of the bent pipe is 90-150 degrees.

[0028] From the above description, it can be seen that the downward structure of the second sewage pipe can facilitate the discharge of sewage.

[0029] Please refer to Figures 1-4 The embodiment one of the utility model is:

[0030] Please refer to Figure 1 and 2As shown: a sewage automatic discharge structure of a road sweeper, comprising a recycling tank bracket 1 and a recycling tank 2, the recycling tank 2 is installed on the recycling tank bracket 1, a detachable sewage discharge pipe 3 is communicated with the bottom of the recycling tank 2, a ball valve 4 is arranged on the sewage discharge pipe 3, an electric push rod 5 is installed at the bottom of the recycling tank 2, a connecting piece 6 is installed at the telescopic end of the electric push rod 5, the connecting piece 6 is connected with the valve rod of the ball valve 4, and the specific connection is that one end of the connecting piece 6 is connected with the valve rod of the ball valve 4 perpendicularly, the other end of the connecting piece 6 is connected with the electric push rod 5, and an angle less than 90 degrees is formed between the electric push rod 5 and the connecting piece 6, so that the telescopic movement of the electric push rod 5 can drive the connecting piece 6 to rotate and open the ball valve.

[0031] Please refer to Figure 3 and 4 As shown: the sewage discharge pipe 3 comprises a first sewage pipe 31 and a second sewage pipe 32, the first sewage pipe 31 is installed at the bottom of the recycling tank 2, and the ball valve 4 is installed on the first sewage pipe 31, the second sewage pipe 32 is installed on the recycling tank bracket 1, a drainage conical bowl 33 is installed at one end of the second sewage pipe 32 close to the first sewage pipe 31, a rubber sealing gasket 34 is arranged on the end of the first sewage pipe 31 away from the recycling tank 2 and matched with the inner wall of the drainage conical bowl 33, a mounting bracket 11 matched with the drainage conical bowl 33 is installed on the recycling tank bracket 1 through bolts, the top of the drainage conical bowl 33 is provided with a mounting flange 35, and the drainage conical bowl 33 is installed on the mounting bracket 11 through the mounting flange 35, when the recycling tank is turned over, the first sewage pipe and the second sewage pipe can be separated, so that the influence of the sewage pipe on the operation of the road sweeper can be avoided, and the elastic sealing cooperation between the first sewage pipe and the second sewage pipe can be formed through the cooperation of the drainage conical bowl and the rubber sealing gasket, so that stable sealing can be ensured even if there is an error between the tank body, the tank bracket and the drainage components;

[0032] At the same time, in order to facilitate the control and operation of the electric push rod 5, the control switch of the electric push rod 5 is connected through a circuit and arranged in the cab of the road sweeper.

[0033] The specific working process of the above embodiment is as follows:

[0034] When the sewage in the recycling tank 2 is discharged, the operator opens the switch of the electric push rod 5 in the cab, the electric push rod 5 pulls the valve rod of the ball valve 4 and the connecting piece 6 to rotate by a certain angle, so as to open the ball valve 4 and discharge the sewage in the recycling tank 2 through the sewage discharge pipe 3;

[0035] When the recycling tank 2 is turned over to clean the garbage inside, the recycling tank 2 turns over with the first sewage pipe 31, the ball valve 4 and the electric push rod 5, and is separated from the second sewage pipe 32, so as to reduce the length of the sewage discharge pipe 3 and avoid the influence of the long sewage discharge pipe 3 on the turning over of the recycling tank 2;

[0036] After the recycling box 2 falls back to the recycling box bracket 1, the rubber sealing gasket 34 at the end of the first sewage pipe 31 slowly contacts the drainage conical bowl 33 on the recycling box bracket 1, thereby forming a seal through the rubber sealing gasket 34, ensuring the sealing of the sewage discharge pipe 3 connection.

[0037] In this embodiment, the structure and working principle of the electric push rod 5 are prior art, and the present embodiment only uses it without improvement, and the telescopic principle is not described in detail here.
