Swing mechanism for front air outlet pipe of general cleaning truck

Abstract

This utility model relates to the field of sweeper technology, specifically a swing mechanism for the front exhaust duct of a sweeper. The linkage assembly includes a rocker arm, a connecting rod, a second rocker arm, and a second connecting rod. One end of the rocker arm is fixed to the output shaft of a motor. The first end of the connecting rod is rotatably connected to the end of the first rocker arm. The middle end of the second rocker arm is rotatably connected to the end of the first connecting rod. The first end of the second rocker arm is rotatably connected to a switch box. The end of the second rocker arm extends out of the switch box opening and is rotatably connected to the first end of the second connecting rod. The motor output shaft drives the first rocker arm to rotate, and the motion is transmitted to the second rocker arm via the first connecting rod, causing the second rocker arm to rotate around its axis within the switch box. The power is then transmitted to the swing assembly on the fixed base via the second connecting rod. Under the pushing and pulling action of the second connecting rod, the swing arm reciprocates around the fixed base, driving the top push-pull rod, bottom push-pull rod, and end collar fixed thereto to move synchronously. Ultimately, the air duct controlled by the collar automatically swings left and right, significantly improving the operational convenience and safety of the sweeper during operation.

Description

Technical Field

[0001] This utility model relates to the field of sweeper technology, specifically to a swing mechanism for the front exhaust pipe of a sweeper. Background Technology

[0002] A general sweeper is short for "ordinary road sweeper". It is a special sanitation vehicle and is mainly used for cleaning urban roads and other areas. Its core function is to replace traditional manual cleaning with mechanized methods, thereby improving efficiency and reducing labor intensity.

[0003] The utility model patent with the number CN223118967U provides a wet leaf sweeper, which is also a general sweeper. The wet leaf sweeper discloses that a duct swing device connected to the air outlet is installed on one side of the seat to control the blowing angle of the air outlet. However, the duct swing device is manually operated by pulling a collar to change the blowing angle of the air outlet. This is inconvenient for the user to operate while driving the vehicle and also increases the safety hazard of the driver holding the handlebars with one hand. Utility Model Content

[0004] The purpose of this utility model is to overcome the defects of the prior art and provide a swing mechanism for the front exhaust pipe of a sweeper to solve the problems mentioned in the background art.

[0005] A swing mechanism for the front exhaust pipe of a sweeper includes: Switch box; A motor that is fixedly installed inside a switch box; A connecting rod assembly fixed to the end of the motor output shaft, the connecting rod assembly including a rocker arm one, a connecting rod one, a rocker arm two, and a connecting rod two. The first end of the rocker arm is fixed to the motor output shaft, the first end of the connecting rod one is rotatably connected to the end of the rocker arm one, the middle end of the rocker arm two is rotatably connected to the end of the connecting rod one, the first end of the rocker arm two is rotatably connected to the switch box, and the end of the rocker arm two extends out of the switch box opening and is rotatably connected to the first end of the connecting rod two. A mounting bracket is installed on one side of the switch box; A rocking assembly is rotatably connected to a fixed base, the upper part of which is rotatably connected to the two ends of a connecting rod.

[0006] Preferably, the two ends of the rocker arm are connected to a shaft, and the shaft is connected to a bearing inside the switch box.

[0007] Preferably, the rocking assembly includes a rocking rod, a top push-pull rod, a bottom push-pull rod, and a collar. The rocking rod is rotatably connected to a fixed base, the top push-pull rod is fixed to the upper end of the rocking rod, the bottom push-pull rod is fixed to the lower part of the front end of the rocking rod, and the collar is fixed to the end of the bottom push-pull rod.

[0008] Preferably, the rocker arm is tilted forward.

[0009] Preferably, a rocker switch is installed on the upper part of the switch box, and the rocker switch is electrically connected to the motor.

[0010] Beneficial effects: The motor output shaft drives the rocker arm one to rotate, and the motion is transmitted to the rocker arm two through the connecting rod one. The rocker arm two rotates around its axis in the switch box, and then the power is transmitted to the rocker assembly on the fixed seat through the connecting rod two. Under the pushing and pulling action of the connecting rod two, the rocker arm swings back and forth around the fixed seat, driving the top push-pull rod, bottom push-pull rod and end collar fixed to it to move synchronously. Finally, the air duct controlled by the collar automatically swings back and forth, which significantly improves the operation convenience and safety of the sweeper during operation.

[0013] Please see Figures 1-3 A swing mechanism for the front exhaust pipe of a sweeper vehicle, comprising: Switch box 1 is located on one side of the sweeper seat and fixed to the side of the sweeper, making it convenient for the driver to operate while sitting in the seat. A rocker switch is installed on the upper part of switch box 1. The motor 5 is fixedly installed in the switch box 1. The rocker switch is electrically connected to the motor 5. The rocker switch is used to control the opening and closing of the motor 5. The motor 5 is powered by the high-capacity battery inside the sweeper. The motor 5 is a motor with a reduction mechanism. Depending on the cleanliness of the road surface and the speed of the sweeper, the motor speed is preferably controlled at 50-70 revolutions per minute. A connecting rod assembly 2 is fixed to the end of the output shaft of motor 5. The connecting rod assembly 2 includes a rocker arm 21, a connecting rod 22, a rocker arm 23, and a connecting rod 25. The first end of the rocker arm 21 is fixed to the output shaft of motor 5. The first end of the connecting rod 22 is rotatably connected to the end of the rocker arm 21. The middle end of the rocker arm 23 is rotatably connected to the end of the connecting rod 22. The first end of the rocker arm 23 is rotatably connected to the switch box 1. A shaft 24 is connected to the first end of the rocker arm 23, and the shaft 24 is connected to an internal bearing in the switch box 1. The end of the rocker arm 23 extends out of the opening of the switch box 1 and is rotatably connected to the beginning of the connecting rod 25. When the motor 5 starts, the output shaft of the motor 5 drives the rocker arm 21 to rotate one revolution. The rocker arm 21 will move backward from the beginning of the connecting rod 22 and then move forward to reset. In this way, the end of the connecting rod 22 will pull the middle end of the rocker arm 23 to swing back and forth, so that the beginning of the rocker arm 23 rotates around the shaft 24, while the end of the rocker arm 23 swings back and forth. In this way, the end of the rocker arm 23 can drive the beginning of the connecting rod 25 to move back and forth. A mounting base 3 is set on one side of the switch box 1. The mounting base 3 is also located on one side of the sweeper seat and fixed to the side of the sweeper. A sway assembly 4 is rotatably connected to the fixed base 3. The upper part of the sway assembly 4 is rotatably connected to the end of the connecting rod 25. The sway assembly 4 includes a sway rod 41, a top push-pull rod 42, a bottom push-pull rod 43, and a collar 44. The sway rod 41 is rotatably connected to the fixed base 3. The top push-pull rod 42 is fixed to the upper end of the sway rod 41. The bottom push-pull rod 43 is fixed to the lower part of the front end of the sway rod 41. The collar 44 is fixed to the end of the bottom push-pull rod 43. The sway rod 41 is tilted forward, forming an angle of 10-15 degrees with the fixed base 3. When the front end of the connecting rod 25 moves back and forth, the top push-pull rod 42 can be pushed and pulled at the end, which can make the sway rod 41 rotate. The sway rod 41 then drives the bottom push-pull rod 43 to swing left and right. The collar 44 is movably sleeved at the air outlet of the front air duct of the sweeper, which can drive the front air duct of the sweeper to swing left and right automatically. This significantly improves the operation convenience and safety of the sweeper during operation.
