Garbage self-dumping road sweeper and garbage self-dumping method

Abstract

The invention discloses a garbage self-dumping road sweeper and a garbage self-dumping method. The garbage self-dumping road sweeper comprises a drive-by-wire chassis, a fan assembly, a box assembly, a sweeping device, a dust suction device and an unmanned driving module. The box assembly comprises a garbage box body, a lifting oil cylinder and an automatic opening and closing mechanism, the fan assembly is arranged on the garbage box body, a rear door is arranged on the garbage box body, and the automatic opening and closing mechanism is arranged between the garbage box body and the rear door and used for driving the rear door to be opened or closed relative to the garbage box body; and the unmanned driving module is used for acquiring feedback data of the sweeping device, the garbage box body and the drive-by-wire chassis and controlling the sweeping device, the fan assembly, the lifting oil cylinder, the dust collection device and the drive-by-wire chassis to execute related instructions. The road sweeper travels to the garbage dumping point along the optimal path, garbage is automatically dumped by adjusting the posture of the road sweeper, manual operation is not needed in the garbage self-dumping process, and the sweeping operation efficiency is remarkably improved.

Description

technical field [0001] The invention relates to a garbage self-dumping road sweeper and a garbage self-dumping method, belonging to the technical field of sanitation vehicles. Background technique [0002] Outdoor mechanized cleaning of roads is an important symbol of sanitation modernization, and road sweepers are widely used in non-motorized lanes, sidewalks, squares and parks for cleaning operations due to their small size and flexible steering. [0003] At present, there are three main forms of garbage dumping for road sweepers on the market: 1. The operator gets off the car to open the locking mechanism and then returns to the cab to tip over the box; 1. The back door is sealed by its own weight and the negative pressure of the box body, and the back door opens when it is tipped over; 3. Use actuators such as cylinders, oil cylinders or electric push rods to control tipping. [0004] However, these several forms of road sweepers still have certain disadvantages, such a...

Problems solved by technology

[0004] However, these several forms of road sweepers still have certain disadvantages. They either need manual operation, which increases the operating cost of the machine, or the components have a complex structure, increased weight, and high production costs.

[0005] In the prior art, the patent application number is 201810929635.8, the application date is August 15, 2018, and the patent title is "An automatic garbage dumping device and its control method", which discloses an automatic garbage dumping device and its The control method, the device includes: car body, carriage, garbage can, first linkage mechanism, second linkage mechanism, bucket body driving device, etc., the bottom of the garbage can is provided with an opening and closing plate, and the opening and closing plate is connected to the rudder through the slider rocker mechanism. The steering gear is used to control the opening and closing of the opening and closing plate through the slider rocker mechanism; the car body is provided with a car body driving device, and the car body driving device is used to drive the car body to follow a preset path, but the patent The structure of the self-dumping device is relatively complicated, and its control method does not distinguish the situation of garbage dumping, nor does it give the equipment to choose the optimal path for driving, and it does not give how to adjust the pose of the equipment after reaching the garbage dumping point.
