Description

[Detailed description of the invention] According to vehicle safety standards, it is prohibited for automobile exhaust pipes to open downward, to the left, or to the right.

For this reason, exhaust pipes generally open toward the rear, or are raised up to create a chimney-like structure to improve the working environment. It was easy for workers to breathe in the exhaust gas, and if the exhaust pipe was opened in the forward direction, rain and wind would enter during driving, reducing engine performance and causing breakdowns, resulting in a very bad work environment.

In order to solve the above-mentioned drawbacks, the present invention aims to exhaust the exhaust gas forward when working at the rear of the vehicle, and to the rear when the vehicle is running, thereby eliminating deterioration of engine performance and other obstacles while working. It is designed to preserve the environment.

To explain the following with reference to figures, FIGS. 1 and 2 show an exhaust opening 2 of a conventional garbage collection vehicle 1, where 3 is a muffler and 4 is an engine.

The exhaust pipe is opened rearward from behind the rear wheel 5 to exhaust the exhaust gas, or the exhaust pipe is set up to discharge the gas rearward from the ceiling.

Reference numeral 6 is a garbage inlet, and since the worker 7 is putting in the garbage as shown in the figure, he is forced to inhale the exhaust gas, which is not good for his health.

Furthermore, when the exhaust pipe is raised, it is difficult to install and also causes problems in engine performance.

・Figure 3 is a basic diagram of the present invention as a solution to this problem.

This is designed to divide the opening of the exhaust pipe into two directions, toward the front shoulder, so that exhaust gas can be exhausted forward and backward.

In this diagram, the exhaust gas is discharged both forward and backward depending on the stop button of the garbage truck and the state of the vehicle, such as when the vehicle is running, so the impact on the worker and the vehicle can be minimized. can.

Figure 4 shows the details of the cross section of the exhaust pipe. This figure utilizes the aerodynamic Venturi effect, and the exhaust gas flows through the exhaust pipe 8, but the garbage truck is not running. At this time, the exhaust gas flows out in the main 1/CB direction due to the forward sloping curve of the rear end portion 8 of the exhaust pipe, and has little effect on the worker T.

When the garbage truck 1 starts running, the wind flows out as shown by arrow B and flows into the venturi exhaust pipe 9.

Since the venturi exhaust pipe 9 is narrow and constricted at the center, a suction effect occurs, and the exhaust gas is effectively exhausted from the exhaust pipe 8, and the ram pressure exerted at the front opening of the venturi exhaust pipe 9 is directed backward in the direction a. flows.

The exhaust pipe 8 and the venturi exhaust pipe 9 do not have to be on the same plane; the exhaust pipe 9 can be made slightly higher than the venturi exhaust pipe 9 to provide a step, thereby preventing rainwater etc. from entering the exhaust pipe 8. This exhaust pipe has a simple structure and is effective because it allows control of the exhaust direction without affecting the health of workers or the performance of the engine, etc.

Claims (1)

[Scope of utility model registration request] As shown in the figure, the rear end of the exhaust pipe 8 is tilted forward, which is the direction of travel of the vehicle, on the exhaust pipe of a garbage collection vehicle that has an inlet at the rear and is operated by a worker at the rear. After bending the venturi exhaust pipe 9, the narrow center part of the venturi exhaust pipe 9, which has three openings open at an angle of 90° so that ram pressure is applied in the direction of travel of the vehicle, and one opening opening at the rear, is inserted after the exhaust pipe 4. An exhaust pipe structure characterized in that the exhaust pipe is connected to the end and controls the direction of the exhaust flow when the vehicle is running and when it is stopped and working.
