Description

Technical Field

[0001] The invention relates to the technical field of high-speed suction sweeper vehicles, and in particular to an airflow circulation type high-speed suction sweeper vehicle. Background Art

[0002] Expressways and trunk roads have become the main form of human transportation and material transportation. Various household garbage generated during human transportation will be thrown on the road, and material transportation vehicles will inevitably spill the transported materials on the road during transportation. In addition, transportation vehicles may also have traffic accidents and mechanical failures, resulting in damaged parts scattered on the road.

[0003] These household garbage, transported materials and damaged vehicle parts scattered on the road will not only affect the smoothness of traffic, but also cause unnecessary damage to the road surface, especially have a huge impact on driving safety, and seriously threaten the personal safety, material safety and vehicle safety of operating vehicles. Therefore, timely cleaning of these road garbage is an important measure to ensure the operational efficiency and operational safety of highways and trunk roads and reduce casualties. However, due to the high speed of vehicles on highways and trunk roads, manual cleaning is no longer in line with the development level of modern productivity. First, manual cleaning and maintenance operations on highways and trunk roads where vehicles are traveling at high speeds are very likely to cause personal injury accidents. Second, the efficiency of manual cleaning and maintenance operations is too low, which affects the operational efficiency of highways and trunk roads. Third, the relevant management departments are facing the dual pressure of the increasing shortage of human labor resources and the continuous increase in human labor costs. Therefore, high-speed or fast suction sweepers that can meet the daily cleaning and maintenance operations of highways and trunk roads have become an urgent need.

[0004] In recent years, a number of high-speed vacuum sweepers have emerged, all claiming to have an operating speed of up to 60km / h or even higher to meet user needs. However, the actual effective operating speed of these high-speed vacuum sweepers is far less than 60km / h (the actual cleaning efficiency at this time is only about 50%, and the relevant standards require that it should not be less than 90%).

[0005] The above-mentioned high-speed suction sweeper has two main operating modes. The first is the mechanical pure sweeping mode, that is, the rear of this high-speed sweeper is equipped with a rotating roller brush in contact with the road surface, and a scraper conveyor belt is installed in front of the rotating roller brush to receive the garbage ejected by the roller brush and send it into the garbage bin in front of the scraper conveyor belt. Its structure and working principle determine that this sweeper can only pick up scattered granular garbage, and its ability to pick up fine dust is very poor. The second is the negative pressure suction sweeping mode, that is, this high-speed sweeper is equipped with a centrifugal fan and a garbage bin, and a suction cup buckled on the road surface. The suction cup is connected to the garbage bin through a flexible hose to form a closed channel. When the fan rotates, a negative pressure airflow can be generated in the suction cup, and the garbage under the suction cup is sucked into the negative pressure airflow channel. After entering the garbage bin, the garbage particles settle in the garbage bin by their own gravity, thereby completing the process of cleaning the road garbage. This type of high-speed sweeper has a very powerful fan, and usually uses an upper-mounted auxiliary engine to drive the fan and other operating devices, that is, a dual-engine power system. The use of a dual-engine power system will inevitably result in excessive power configuration of the entire vehicle, high fuel consumption, high noise, and high cost of use.

[0006] In summary, the existing high-speed vacuum sweepers all have the problem of insufficient cleaning rate. The fundamental reason is that the suction effect is not ideal during high-speed operation. The underlying reason is that the negative pressure airflow acts on the road garbage for too short a time, which is not enough to start the garbage from the road. Therefore, the direct way to solve this problem is to solve the problem of rapid start of garbage particles in a very short time. Summary of the invention

[0043] Example 1

[0044] This embodiment provides an air circulation high-speed suction sweeper, the purpose of which is to solve the problem that the high-speed suction sweeper adopts a dual-engine power system resulting in an excessively large vehicle power configuration. Figure 1-Figure 3 , the specific structure of this embodiment will be described in detail below.

[0045] An air circulation type high-speed vacuum sweeper comprises a chassis 1, a garbage box 2 arranged on the chassis 1, a power distribution component 3 arranged on the chassis 1 and a cleaning suction cup component 4 arranged at the rear end of the chassis 1.

The power output port of one power take-off transfer case 31 is connected to the fan 7 to drive the upper operating device of the high-speed suction and sweeping vehicle, and provide positive pressure airflow and negative pressure airflow for the airflow circulation box 6. The positive pressure airflow and the negative pressure airflow flow to the cleaning suction cup assembly 4, and the cleaning suction cup assembly 4 blows the road garbage through the positive pressure airflow to start the garbage particles, and then sucks the garbage particles into the garbage compartment through the negative pressure airflow, so as to achieve rapid and reliable suction and pickup of the garbage particles.

[0049] When necessary, other power output ports of the power take-off transfer case 31 can be connected to a water pump to drive the water pump to extract clean water from the clean water tank 5 and spray the water on the ground using a nozzle.

[0050] Specifically, the power take-off transfer case 31 is arranged on the frame of the chassis 1 through a mounting seat and is located behind the gearbox 8; the total power input port of the power take-off transfer case 31 is connected to the gearbox 8 through a front drive shaft 32; one of the power output ports of the power take-off transfer case 31 is connected to the rear drive axle 9 through a rear drive shaft 33.

[0051] In this embodiment, the power take-off transfer case 31 is installed in series on the frame of the chassis 1 located behind the gearbox 8 through a mounting seat. The total power input port of the power take-off transfer case 31 is connected to the output shaft of the gearbox 8 through a front drive shaft 32, so that all the power of the chassis engine can be taken out and distributed in different transmission forms. Among them, the power output port of at least one power take-off transfer case 31 is connected to the rear drive axle 9 through a rear drive shaft 33, so that the power of the chassis engine is transmitted to the rear wheels of the chassis 1, so as to drive the high-speed vacuum sweeper to move.

[0052] Optionally, a power output port of a power take-off transfer case 31 can drive the fan 7 to operate through a belt connection, and the fan 7 provides positive pressure airflow and negative pressure airflow for the airflow circulation box 6.

[0053] Optionally, a power output port of a power take-off transfer case 31 can be connected to a water pump via a belt to drive the water pump to operate, and the clean water inside the clean water tank 5 is extracted by the water pump.

[0054] Example 2

[0055] Based on Example 1, this embodiment provides an air circulation box 6 of an air circulation type high-speed suction and sweeping vehicle, the purpose of which is to form positive pressure airflow and negative pressure airflow in the air circulation box, referring to Figure 4-Figure 6 , the specific structure of this embodiment will be described in detail below.

[0056] A first partition plate 64 is provided inside the air circulation box 6 , and the first partition plate 64 partitions the inside of the air circulation box 6 into a fan compartment 61 and a garbage compartment 62 forming a negative pressure air flow channel inside.

[0057] Specifically, the negative pressure airflow outlet 610 of the garbage compartment 62 is connected to the air inlet of the fan 7; a vertical dust suction pipe 63 is arranged inside the garbage compartment 62, and the bottom of the vertical dust suction pipe 63 is connected to the cleaning suction cup assembly 4.

[0058] In this embodiment, the airflow circulation box 6 is divided into a fan compartment 61 and a garbage compartment 62 by a first partition plate 64 inside the airflow circulation box 6. The fan compartment 61 is used to place the fan 7. The fan 7 is connected to a power output port of the power take-off transfer case 31 through a belt passing through the airflow circulation box 6, thereby driving the fan 7.

[0059] The garbage bin 62 can be used as a negative pressure airflow channel. The negative pressure airflow outlet 610 of the garbage bin 62 is opened above the fan compartment 61 so as to be connected with the air inlet of the fan 7, so that the garbage bin 62 generates a negative pressure airflow. At the same time, a vertical dust suction pipe 63 is arranged inside the garbage bin 62. The negative pressure environment in the garbage bin 62 is transferred to the cleaning suction cup assembly 4 through the vertical dust suction pipe 63 to absorb the road garbage, thereby sucking the road garbage into the garbage bin 62.

[0060] Optionally, the bottom of the garbage bin 62 may be inclined. The inclined bottom of the garbage bin 62 makes it easy to pile the garbage sucked into the garbage bin 62 at the rear outlet of the garbage bin 62 for subsequent cleaning. At the same time, the inclined bottom of the garbage bin 62 can form a recycling space below the garbage bin 62, for example, filling it with clean water to form a subsidiary water tank, thereby increasing the overall clean water load capacity.

[0061] Specifically, a second partition plate 67 is provided on the upper part of the air circulation box 6, and a positive pressure air flow channel is formed between the second partition plate 67 and the top plate of the air circulation box 6; the positive pressure air flow inlet 68 of the positive pressure air flow channel is connected to the air outlet of the fan 7;

[0062] Positive pressure air flow risers 69 are provided on both sides of the rear end of the garbage compartment 62, one end of the positive pressure air flow riser 69 is connected to the positive pressure air flow channel, and the other end of the positive pressure air flow riser 69 passes through the bottom plate of the garbage compartment 62 and is connected to the cleaning suction cup assembly 4.

[0063] In this embodiment, a second partition 67 is provided above the air circulation box 6, and a positive-pressure airflow channel is formed between the second partition 67 and the top plate of the air circulation box 6 to receive the positive-pressure airflow blown out by the fan 7. The positive-pressure airflow inlet 68 of the positive-pressure airflow channel is opened above the fan compartment 61 so as to be connected with the air outlet of the fan 7, so that a positive-pressure airflow is formed in the positive-pressure airflow channel. At the same time, positive-pressure airflow risers 69 are opened on both sides of the rear end of the garbage compartment 62. The positive-pressure airflow risers 69 transfer the positive-pressure airflow in the positive-pressure airflow channel to the cleaning suction cup assembly 4 to back-blow the road garbage, so that the road garbage is lifted under the back-blow of the positive-pressure airflow, and is quickly started and forms a directional reflection to help the reliable suction and pickup of road garbage particles.

[0064] Specifically, a diverter plate 65 is provided on the lower surface of the second partition plate 67 located directly above the vertical dust suction pipe 63 , and a baffle plate 66 is provided between the vertical dust suction pipe 63 and the negative pressure air flow outlet 610 .

[0065] In this embodiment, a diverter plate 65 is provided on the lower surface of the second partition plate 67 . The cross section of the diverter plate 65 is triangular, so as to divert the garbage sucked up from the vertical dust suction pipe 63 and prevent the garbage sucked up from the vertical dust suction pipe 63 from directly hitting the second partition plate 67 .

[0066] A baffle 66 is provided between the vertical dust suction pipe 63 and the negative pressure air flow outlet 610 , and the baffle 66 prevents garbage from rushing toward the negative pressure air flow outlet 610 , so as to block the negative pressure air flow outlet 610 .

[0067] Optionally, a filter screen is provided at the negative pressure air flow outlet 610 , and the filter screen can prevent garbage from flowing toward the fan 7 and damaging the fan 7 .

[0068] Example 3

[0069] Based on embodiments 1 and 2, this embodiment provides a cleaning suction cup assembly 4 of an air circulation high-speed suction sweeper, the purpose of which is to quickly start the road garbage through the positive pressure airflow and quickly suck up the road garbage through the negative pressure airflow. Figure 7-10 , the specific structure of this embodiment will be described in detail below.

[0070] The cleaning suction cup assembly 4 includes a suction cup box 41 and a suction cup traction frame 42 .

[0071] One end of the suction cup traction frame 42 is mounted on a mounting seat of the chassis 1 frame, and the other end of the suction cup traction frame 42 is connected to the upper surface of the suction cup box 41 .

[0072] In this embodiment, the suction cup box 41 is installed on a preset mounting seat of the chassis 1 frame through the suction cup traction frame 42, and the suction cup box 41 can also be adjusted in angle through the suction cup traction frame 42.

[0073] Optionally, a sweeping disc may be installed on a mounting seat preset on the vehicle frame to gather garbage.

[0074] Optionally, a high-pressure water nozzle can be installed on a mounting seat preset on the frame to extract clean water from the clean water tank 5 to spray the ground and assist the sweeping plate in gathering garbage.

[0075] Optionally, a suspension rope is installed on the upper surface of the suction cup box 41, one end of the suspension rope is connected to the upper surface of the suction cup box 41, and the other end of the suspension rope is connected to the vehicle frame.

[0076] Specifically, the suction cup housing 41 includes a suction cup housing 411 with an opening at the bottom, a through groove 412 is provided in the middle of the upper surface of the suction cup housing 411, a middle partition plate 414 is provided in the through groove 412 through two sealing plates 413, and the middle partition plate 414 divides the interior of the suction cup housing 411 into a positive pressure back-blowing chamber 415 and a negative pressure dust suction chamber 416;

[0077] The positive-pressure back-blowing chamber 415 is connected to the positive-pressure airflow channel via the positive-pressure airflow connecting pipe 417 ; the negative-pressure dust suction chamber 416 is connected to the negative-pressure airflow channel via the negative-pressure airflow connecting pipe 418 .

[0078] In this embodiment, the bottom of the suction cup shell 411 is designed to be open, and a through groove 412 is opened on the upper surface. Inclined flanges are provided on both sides of the inner side of the through groove 412, and a sealing plate 413 is installed on the flange by bolts. The sealing plate 413 is made of flexible material, so that a closed gap is formed by the two sealing plates 413 to clamp and fix the middle partition 414, and the flexible sealing plate 413 can allow the middle partition 414 to swing at a certain angle and slide up and down, thereby providing the necessary degree of freedom for the adjustment of the middle partition 414.

[0079] The middle partition 414 is an arc-shaped plate or a flat plate, and its forward or backward tilt angle and height from the ground can be adjusted by two sealing plates 413 to obtain different forward or backward tilt angles and heights from the ground. The middle partition 414 is not only a space structure partition of the positive pressure back-blowing chamber 415 and the negative pressure dust suction chamber 416, but also an adjustment mechanism for obtaining an ideal suction-assisting effect according to different operating speeds and positive pressure back-blowing airflow speeds.

[0080] Furthermore, the interior of the suction cup housing 411 is partitioned into a positive-pressure back-blowing chamber 415 and a negative-pressure dust suction chamber 416 by the middle partition plate 414; the positive-pressure back-blowing chamber 415 and the negative-pressure dust suction chamber 416 are both a transversely long and narrow space.

[0081] The positive pressure airflow connecting pipe 417 above the positive pressure back-blowing chamber 415 is connected to the positive pressure airflow riser 69 of the positive pressure airflow channel through a corrugated hose, thereby guiding the positive pressure airflow generated by the fan 7 to the positive pressure back-blowing chamber 415 .

[0082] The negative pressure airflow connecting pipe 418 above the negative pressure dust suction chamber 416 is connected to the vertical dust suction pipe 63 of the negative pressure airflow channel through a corrugated hose, thereby guiding the negative pressure environment generated by the fan 7 in the garbage compartment 62 to the negative pressure dust suction chamber 416.

[0083] The present invention adopts a suction cup structure with positive pressure airflow and negative pressure airflow dual chambers integrated and arranged in parallel, so that the suction cup has positive pressure airflow and negative pressure airflow acting on the road garbage particles at the same time during operation. When positive pressure blowing is formed on the road garbage in the positive pressure back-blowing chamber 415, the positive pressure blowing blows toward the road garbage at a relatively high speed and a certain forward angle, and is reflected on the road surface, so that the road garbage starts quickly, and the road garbage will move forward and rise with the high-speed airflow, and enter the negative pressure dust suction chamber 416 at the same time, and rise into the garbage compartment 62 under the action of the negative pressure airflow, so as to realize the rapid and reliable suction and pickup of the road garbage particles, and improve the rapid suction and pickup ability of the suction cup.

[0084] Specifically, the rear wall plate of the suction cup shell 411 is provided with a blowing guide plate 43 through a rotating shaft, an adjusting nut seat 431 is provided on the outer wall of the blowing guide plate 43, and a fixing nut seat 432 is provided on the front wall plate of the suction cup shell 411. The fixing nut seat 432 and the adjusting nut seat 431 are connected by a swinging adjusting screw 433.

[0085] In this embodiment, the air blowing guide plate 43 is an arc-shaped plate or a flat plate, which is horizontally hinged on the rear wall plate of the suction cup housing 411 through a rotating shaft. The spacing between the fixed nut seat 432 and the adjusting nut seat 431 is adjusted by swinging the adjusting screw 433. The nuts of the fixed nut seat 432 and the adjusting nut seat 431 can rotate relative to the nut seat, thereby adjusting the backward angle of the air blowing guide plate 43. The change of this angle can change the reverse blowing angle. When the operating speed is different, the reverse blowing at different angles is required to maintain an appropriate reflection angle to obtain the best suction-assisting effect.

[0086] Specifically, the front wall plate of the suction cup shell 411 is provided with a suction cup windshield curtain 44 through a core shaft. The suction cup windshield curtain 44 includes a plurality of windshield sub-curtains 441 with the top sleeved on the core shaft. The windshield sub-curtains 441 include a first sub-curtain 442 and a second sub-curtain 443. The first sub-curtain 442 and the second sub-curtain 443 are relatively staggered.

[0087] In the present embodiment, the suction cup wind shield curtain 44 is composed of a plurality of wind shield sub-curtains 441 arranged across the entire width of the suction cup shell 411. Under normal operating conditions, each section of the wind shield sub-curtain 441 of the suction cup wind shield curtain 44 is in a drooping state or in an inwardly inclined state at a certain angle. When there are larger-sized garbage particles (such as beverage bottles, etc.) in front of the suction cup wind shield curtain 44, the wind shield sub-curtains 441 hit by the garbage particles can swing inward, thereby increasing the ground clearance of the corresponding position of the suction cup shell 411, allowing the garbage particles to enter the interior of the suction cup shell 411 and then be sucked up. When large-sized garbage enters the suction cup shell 411, the inward-swinging wind shield sub-curtain 441 automatically resets to maintain the original ground clearance, thereby preserving the normal air intake and wind speed of the suction cup shell 411.

[0088] Specifically, the suction cup traction frame 42 includes a fixed rod 421, one end of which is installed on a mounting seat of the chassis 1 frame; the other end of the fixed rod 421 is provided with a fixed support rod 422 and an angle adjustment screw 423 in sequence; the fixed support rod 422 is hinged to the upper surface of the suction cup shell 411 located at the positive pressure backblowing chamber 415; the angle adjustment screw 423 is hinged to the upper surface of the suction cup shell 411 located at the negative pressure dust suction chamber 416.

[0089] In this embodiment, the suction cup traction frame 42 follows the chassis 1 to move forward, and there are two front and rear hinge points between the suction cup traction frame 42 and the suction cup housing 411.

[0090] The position where the fixed support rod 422 is hinged to the upper surface of the suction cup housing 411 located at the positive pressure back-blowing chamber 415 is the front hinge point, which is a single-degree-of-freedom hinge and can only rotate coaxially.

[0091] The angle adjustment screw 423 is hinged to the upper surface of the suction cup shell 411 located at the negative pressure dust suction chamber 416 as a rear hinge point. The angle adjustment screw 423 is a double-headed reverse-threaded bolt. One end of the double-headed bolt is connected to the end of the fixed rod 421 through a hinge nut, and the other end of the double-headed bolt is connected to the hinge nut on the upper surface of the suction cup shell 411. The hinge nut can rotate relative to the fixed rod 421 and the suction cup shell 411 respectively. When the double-headed bolt is rotated, the suction cup shell 411 can be rotated around the front hinge point relative to the suction cup traction frame 42, thereby adjusting the ground angle of the suction cup shell 411 relative to the road surface.

[0092] Although the specific implementation of the invention is described in detail in conjunction with the drawings, it should not be understood as limiting the scope of protection of this patent. Within the scope described in the claims, various modifications and variations that can be made by those skilled in the art without creative work still fall within the scope of protection of this patent.
