Description

Technical Field

[0001] This invention relates to a garbage sweeper cleaning device and a garbage sweeper, belonging to the technical field of road cleaning equipment. Background Technology

[0002] With the rapid advancement of urbanization and the continuous increase in urban road mileage, road sanitation has become one of the core indicators for measuring the level of urban civilization, placing higher demands on the cleaning efficiency, coverage, and practicality of road cleaning equipment. As a core piece of equipment integrating road sweeping, garbage collection, and transportation, garbage sweepers effectively reduce manual labor intensity and improve cleaning efficiency. They have been widely used in various scenarios such as urban main roads, residential roads, and industrial parks, becoming key equipment for maintaining urban environmental cleanliness.

[0003] However, the existing sweeping devices of garbage sweepers still have many shortcomings in practical applications, making it difficult to meet the needs of comprehensive, efficient, and stable sweeping. The specific defects are as follows:

[0004] Existing sweepers mostly employ a single sweeping mode, failing to thoroughly remove both hard and lightweight waste. Some equipment only uses mechanical brushes to sweep away hard waste such as pebbles and paper scraps, but the sweeping effect on lightweight waste such as dust, powder, and small debris is limited, especially in areas like roadside edges and road cracks, where lightweight waste easily remains, creating blind spots. Other equipment relies on airflow to sweep away lightweight waste but cannot effectively collect heavier hard waste, forcing the sweeping operation to be carried out in stages, resulting in low overall efficiency and making it difficult to achieve a thorough cleaning in one go. Summary of the Invention

[0005] This invention provides a garbage sweeper cleaning device and a garbage sweeper to solve the problem of incomplete cleaning coverage and obvious blind spots in the prior art.

[0006] This invention provides a garbage sweeper cleaning device and a garbage sweeper, which are installed on the garbage sweeper and include:

[0007] The front-mounted sweeping assembly is located at the front of the bottom of the garbage sweeper and is used to sweep and collect hard garbage on the road surface.

[0008] The rear-mounted air sweeping assembly is located behind the front-mounted sweeping assembly along the vehicle's travel direction, and is used to collect and transport lightweight waste remaining on the road surface by airflow.

[0009] The rear-mounted air scavenging assembly includes:

[0010] A directional sweeping device has at least one air inlet for directional blowing of air onto the road surface to blow lightweight waste to a predetermined collection path;

[0011] A waste conveying assembly, connected to the rear of the directional purging device, is used to receive and convey the waste that has been purged and concentrated.

[0012] The waste conveying assembly includes a conveying air pump and a conveying channel. The conveying air pump blows air into the conveying channel to form an airflow to propel the waste along the channel.

[0013] The bottom of the conveying channel is an open structure, with a flexible sealing gasket and a wear-resistant guide pad respectively provided on both sides of the bottom. The bottom of both the flexible sealing gasket and the wear-resistant guide pad are in contact with the ground, forming a basically sealed conveying cavity together with the conveying channel and the ground.

[0014] Preferably, the front cleaning assembly includes:

[0015] A circular sweeper is driven by a motor to rotate in a circular motion, with its brush head in contact with the ground.

[0016] A primary waste collection bin is located behind the rotary sweeper and is used to receive the waste swept in by the rotary sweeper;

[0017] The primary waste collection bin has a guide-type waste inlet on the side facing the circular sweeper, and the bottom of the guide-type waste inlet is inclined.

[0018] Preferably, the air inlet of the directional blowing device is connected to the garbage sweeper through an anti-collision structure;

[0019] The anti-collision structure includes:

[0020] Install the base rod and fix it to the garbage sweeper;

[0021] A crash bar is arranged parallel to the mounting base bar, and the air inlet is installed on the crash bar;

[0022] A hinged connecting rod, the two ends of which are respectively hinged to the mounting base rod and the anti-collision rod, so that the anti-collision rod can deflect relative to the mounting base rod;

[0023] A reset elastic element is disposed between the mounting base rod and the anti-collision rod, and is used to reset the anti-collision rod after it is deflected by an external force.

[0024] Preferably, there are two hinged links, located on both sides of the anti-collision bar, and the two hinged links are parallel to each other;

[0025] The reset elastic element is a spring.

[0026] Preferably, the flexible sealing gasket is made of flexible rubber material, and the wear-resistant guide pad is made of hard rubber material.

[0027] Preferably, the flexible sealing gasket and the wear-resistant guide pad extend along the length direction of the conveying channel.

[0028] Preferably, the waste conveying assembly further includes a lifting device, which is located at the end of the conveying channel away from the conveying air pump, for lifting the waste in the conveying channel and transferring it to the waste bin of the waste sweeper.

[0029] Preferably, the air outlet of the directional purging device is connected to the purging air pump.

[0030] Preferably, a garbage sweeper includes a garbage truck and a garbage sweeper cleaning device, wherein the garbage sweeper cleaning device is disposed at the bottom of the garbage truck.

[0031] The beneficial effects of this invention are:

[0032] This invention provides a garbage sweeper cleaning device and a garbage sweeper, which achieves dual cleaning of hard and light garbage through the cooperation of a front sweeping assembly and a rear air sweeping assembly. The front sweeping assembly effectively collects hard garbage such as stones through a rotary sweeper and a primary garbage collection bin, while the rear air sweeping assembly collects and transports light garbage such as floating dust and debris left on the roadside through a directional blowing device and a garbage conveying component. The dual cleaning mode significantly improves cleaning efficiency and quality, achieving a thorough cleaning effect in one go.

[0033] In response to the problem of blind spots in existing sweepers, the rear-mounted air sweeping assembly of this application effectively makes up for the lack of sweeping in areas such as roadside edges and road surface gaps by the front-mounted sweeping assembly. Through airflow collection and conveying technology, it ensures that lightweight garbage in these areas can also be thoroughly removed.

[0034] The rotary sweeper in the front cleaning assembly is driven by a motor to rotate in a circular motion. Its brush head contacts the ground and can effectively sweep hard garbage into the primary garbage collection bin. The primary garbage collection bin has a guide-type garbage inlet design with an inclined bottom, which facilitates the smooth entry of garbage and improves garbage collection efficiency.

[0035] The directional blowing device blows air directionally onto the road surface through at least one air outlet, blowing lightweight waste to a predetermined collection path; the waste conveying component generates airflow through a delivery pump and conveying channel, propelling the waste along the channel to the lifting device, and finally transferring it to the waste bin of the waste sweeper, ensuring efficient collection and transportation of lightweight waste;

[0036] The air inlet of the directional blowing device is connected to the garbage sweeper through the anti-collision structure. When the garbage truck encounters an obstacle during its journey, the anti-collision bar can deflect relative to the mounting base bar to prevent the air inlet from directly contacting the obstacle and being damaged. After the obstacle is removed, the reset elastic element resets the anti-collision bar to ensure that the air inlet always maintains the preset blowing angle.

[0037] The bottom of the conveying channel of the waste conveying component is open, with flexible sealing gaskets and wear-resistant guide pads on both sides. The flexible sealing gaskets are made of flexible rubber material, which can adapt to the undulations of the road surface and ensure the sealing effect. The wear-resistant guide pads are made of hard rubber material, which improves wear resistance. This makes the conveying channel and the ground form a basically sealed conveying cavity, which prevents waste from escaping during the conveying process due to poor sealing and improves the efficiency of waste conveying.

[0046] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0047] This invention provides a garbage sweeper cleaning device and a garbage sweeper, which includes a garbage truck 1. The bottom of the garbage truck 1 is provided with a front sweeping assembly 2 and a rear air sweeping assembly 3 for sweeping garbage. The front sweeping assembly 2 and the rear air sweeping assembly 3 are arranged sequentially along the vehicle's travel direction. The front sweeping assembly 2 includes a rotary sweeper 21 and a primary garbage collection box 22 that matches the rotary sweeper 21. The rotary sweeper 21 is located behind the primary garbage collection box 22. The primary garbage collection box 22 has a guide garbage inlet 221 for garbage to enter, facing the rotary sweeper 21. The bottom of the guide garbage inlet 221 is inclined. The rotary sweeper 21 is driven by a motor 001 to rotate in a circular motion.

[0048] The rear air sweeping assembly 3 includes a directional sweeping device 31 for sweeping garbage and a garbage conveying component 32 for conveying garbage. The directional sweeping device 31 includes multiple air ports 311. The multiple air ports 311 are connected to the garbage truck 1 through an anti-collision structure 312. The air ports 311 are connected to the sweeping air pump 002 for blowing air.

[0049] The anti-collision structure 312 includes a mounting base rod 3121 fixedly connected to the garbage truck 1, and an anti-collision rod 3122 arranged parallel to the mounting base rod 3121. The mounting base rod 3121 and the anti-collision rod 3122 are connected by a hinged connecting rod 3123. The hinged connecting rod 3123 is located on both sides of the anti-collision rod 3122, and the two hinged connecting rods 3123 are parallel to each other. The two ends of the hinged connecting rod 3123 are respectively hinged to the mounting base rod 3121 and the anti-collision rod 3122. A spring 3124 for resetting is provided between the mounting base rod 3121 and the anti-collision rod 3122.

[0050] The waste conveying assembly 32 includes a conveying air pump 321 and a conveying channel 322. The conveying air pump 321 is located at one end of the conveying channel 322 and blows air into the conveying channel 322. The end of the conveying channel 322 away from the conveying air pump 321 is provided with a matching lifting device 003.

[0051] The conveying channel 322 is designed with channel steel and has an open bottom. Flexible sealing gasket 3221 and wear-resistant guide gasket 3222 are respectively provided on both sides of the bottom of the conveying channel 322. The wear-resistant guide gasket 3222 is made of hard rubber, and the flexible sealing gasket 3221 is made of flexible rubber. The bottoms of the flexible sealing gasket 3221 and the wear-resistant guide gasket 3222 are both in contact with the ground, so that the conveying channel 322, the flexible sealing gasket 3221, the wear-resistant guide gasket 3222 and the ground form a sealed waste conveying channel.

[0052] In use, the garbage truck 1 is equipped with a driver's cab, and the garbage truck 1 has a garbage bin for storing garbage inside the truck body. The user operates the garbage truck 1 from the driver's cab to move the garbage truck 1 forward. The rotary sweeper 21 contacts the ground and rotates counterclockwise by the motor 001. During the rotation, the rotary sweeper 21 sweeps hard garbage such as stones on the road surface into the primary garbage collection bin 22 at the rear. The bottom of the guide-type garbage inlet 221 is inclined to facilitate garbage entry. A rear air sweeping assembly 3 is located behind the front sweeping assembly 2. The rear air sweeping assembly 3 includes a directional blowing device 31 and a garbage conveying component 32. The directional blowing device 31 then blows away the floating dust and debris remaining on the roadside. The directional blowing device 31 uses the air outlet 311 to bring the floating dust and debris closer to the roadside and prevents it from being blocked by the front sweeping assembly. The garbage swept by the sweeping assembly 2 is moved to the end away from the road edge. As the garbage truck 1 moves, the garbage enters the sealed cavity formed by the conveying channel 322, the flexible sealing gasket 3221, the wear-resistant guide pad 3222, and the ground. The conveying air pump 321 at one end of the conveying channel 322 starts working, blowing air into the conveying channel 322. This causes the garbage in the conveying channel 322 to move under the action of the airflow. The garbage moves to the side of the lifting device 003, which then conveys the garbage in the conveying channel 322 into the garbage bin in the garbage truck 1. This achieves the dual effect of physical collection of hard garbage and airflow collection of light garbage, covering the cleaning blind spots of the existing sweeping device. The flexible rubber pad can adapt to the undulations of the road surface to ensure the sealing effect, while the hard rubber pad improves the wear resistance. At the same time, the second air pump blows air into the sealed cavity, and the airflow forms a directional thrust to prevent garbage from escaping due to poor sealing, greatly improving the garbage conveying efficiency.

[0053] The bottom of the garbage truck 1 is equipped with an anti-collision structure 312 for mounting an air inlet 311. The anti-collision structure 312 includes a mounting base rod 3121 fixedly connected to the garbage truck 1 and an anti-collision rod 3122 for mounting the air inlet 311. The mounting base rod 3121 and the anti-collision rod 3122 are connected by a hinged connecting rod 3123. The two ends of the hinged connecting rod 3123 are respectively hinged to the mounting base rod 3121 and the anti-collision rod 3122. A spring 3124 is provided between the mounting base rod 3121 and the anti-collision rod 3122. When the garbage truck 1 moves the air inlet 311... When the vehicle encounters obstacles such as on the road, the anti-collision bar 3122 is compressed. Both ends of the anti-collision bar 3122 begin to deform around the hinge point with the hinge link 3123 to prevent the air outlet 311 from directly contacting the obstacle, thereby preventing the air outlet 311 from being damaged by collision. During the deformation of the anti-collision bar 3122 around the hinge point with the hinge link 3123, the spring 3124 begins to deform under force. When the anti-collision bar 3122 is no longer compressed, the spring 3124 drives the anti-collision bar 3122 to reset, ensuring that the air outlet 311 always maintains the preset blowing angle.

[0054] Compared with the existing design, the circular sweeper 21 contacts the ground and rotates counterclockwise by the motor 001. During the rotation, it can sweep hard garbage such as stones on the road surface into the garbage collection chamber 22 at the rear. It can effectively collect hard garbage physically, collect hard garbage more centrally and efficiently, and avoid garbage scattering everywhere during the sweeping process. The bottom of the first garbage inlet 221 is set at an inclination to facilitate garbage to enter the garbage collection chamber 22. The air blowing port 311 sweeps the floating dust and other garbage near the roadside that have not been swept by the first sweeping component 2 to the end away from the edge of the road, making up for the sweeping blind spots of the first sweeping component 2 and making the sweeping more comprehensive and thorough. The dual sweeping method can significantly improve the sweeping quality.

[0055] When the garbage truck 1, carrying the air inlet 311, encounters obstacles such as on the road, the anti-collision bar 3122 is compressed. The two ends of the anti-collision bar 3122 deform around the hinge point with the connecting rod 3123, preventing the air inlet 311 from directly contacting the obstacle and thus preventing collision damage. When the anti-collision bar 3122 is no longer compressed, the spring 3124 drives the anti-collision bar 3122 to reset, ensuring that the air inlet 311 always maintains the preset blowing angle. This anti-collision structure 312 effectively protects the air inlet 311, extends its service life, and ensures the normal operation of the air blowing assembly 31.

[0056] The bottom of the conveying channel 322 is open, and a first rubber pad 3221 and a second rubber pad 3222 are respectively provided on both sides of the bottom. The second rubber pad 3222 is made of hard rubber, and the first rubber pad 3221 is made of flexible rubber. The bottoms of the first rubber pad 3221 and the second rubber pad 3222 are both in contact with the ground, so that the conveying channel 322, the first rubber pad 3221, the second rubber pad 3222 and the ground form a sealed garbage conveying channel. The flexible sealing pad 3221 can adapt to the undulation of the road surface and ensure the sealing effect, while the second rubber pad 3222 improves the wear resistance and can prevent garbage from escaping during the conveying process due to poor sealing, thereby improving the garbage conveying efficiency.

[0057] Garbage enters the sealed cavity formed by the conveying channel 322, the first rubber pad 3221, the second rubber pad 3222, and the ground. The second air pump 321 blows air into the sealed cavity, and the airflow forms a directional thrust, causing the garbage in the conveying channel 322 to move under the action of the airflow. The garbage moves to the side of the lifting device 003, and the lifting device 003 transfers the garbage in the conveying channel 322 to the garbage bin in the garbage truck 1. The airflow conveying method has a relatively simple structure and can more effectively promote the movement of garbage, reduce the blockage of garbage during the conveying process, and further improve the garbage conveying efficiency.

[0058] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the invention, such designs should fall within the protection scope of the present invention.
