Detailed implementation manners

[0032] The following is a further detailed description of the specific implementation manners of the present invention by describing the embodiments with reference to the accompanying drawings, aiming to help those skilled in the art have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention and to facilitate its implementation.

[0033] As Figure 1 And Figure 2 shown, the dust collection system of the road sweeper includes a chassis 1 and a rear roof 2 of the cab. A dust collection box 3 and a dust collecting box 4 are respectively provided at the top and bottom of the chassis 1. A filter barrel 5 is provided in the dust collection box 3. The dust collecting box 4 is communicated with the dust collection box 3. A dust suction system is provided between the rear roof 2 of the cab and the dust collection box 3. The dust collecting box 4 and the dust collection box 3 are installed on the chassis 1 through fixing bolts and quick buckles. The air suction fan cavity and the motor assembly of the dust suction fan 21 are sequentially installed on the rear roof 2 of the cab through fixing bolts. The flanging 36 at the bottom of the dust collection box 3 is provided with uniformly arranged fixing holes 37 to improve the stability of the dust collection box 3 fixed on the chassis 1.

[0034] As Figure 1 , Figure 2 and Figure 6 shown, the dust collection system includes a dust collection fan 21. A dust collection chamber 22 is provided inside the rear roof panel 2 of the cab. The dust collection chamber 22 is located above the dust collection box 3. The dust collection fan 21 is installed in the dust collection chamber 22. One end of the dust collection chamber 22 and a filter barrel 5 are connected by an air suction bellows 23. The dust collection chamber 22 is connected to the dust collection box 3 through the air suction bellows 23. When the dust collection fan 21 is started to achieve the suction function, a negative pressure is formed inside the dust collection box 3, and the garbage in the external environment can be smoothly swept by the brush head 11, and the road cleaning effect is more thorough. The heavier garbage will enter the dust collection bin 4 for convenient collection and treatment. Among them, the dust, due to its small weight, follows the air flow into the dust collection box 3 and adheres to the filter barrel 5, thereby avoiding secondary pollution caused by the dust being discharged along the air suction bellows 23. The dust collection fan 21 constitutes a separate air duct inside the vehicle through the air suction bellows 23, and the suction is smoother, without affecting the vehicle structure, which is convenient for production, installation and after-sales service. The dust collection fan 21 is installed on the roof, making full use of the internal structure space of the vehicle. The position of the filter barrel 5 is set at a high position of the dust collection box 3. Under the influence of gravity, the heavier garbage will fall into the integrated box, so that the garbage will not be sucked in. The high-position design enables the filter barrel 5 to always remain dry, without caking and blocking, and at the same time greatly increases the difficulty of the dust being discharged along the air suction bellows 23. Compared with the prior art, the filtering effect is more thorough, there is no secondary pollution, and the structure is reasonable and convenient for installation and maintenance. The filtering area of the filter barrel 5 reaches 8.5 ㎡, and it is equipped with two 365W fans. The filtering system efficiency is higher than that of the same type of products on the market, and it can well control the dust. The dust collection chamber 22 is arranged with filter cotton with a through diameter of 10 μm, which can effectively block the dust and prevent secondary pollution.

[0035] As shown in Figures 3 to Figure 5-2 shown, a dust shaking motor 51 is connected to a mounting plate 57. The mounting plate 57 is provided at one end of the filter barrel 5. The dust shaking motor 51 is provided on the mounting plate 57. The output end of the dust shaking motor 51 is connected to the filter barrel 5. A plurality of dust shaking blades 52 are provided in the dust collection box 3. The end of the dust shaking blade 52 contacts the filter barrel 5. The end of the dust shaking blade 52 is inserted into the gap of the filter paper on the surface of the filter barrel 5. When the filter barrel 5 needs to be cleaned, when the dust shaking motor 51 is started to drive the filter barrel 5 to rotate, the dust shaking blade 52 will play a continuous vibrating role, so that the dust attached to the filter barrel 5 is shaken off, and the dust enters the dust collection bin 4 under the action of gravity. The plurality of dust shaking blades 52 are arranged at a certain interval, improving the dust shaking effect and the cleaning efficiency of the filter barrel 5.

[0036] As Figures 5-1 to 7As shown, the output end of the dust-vibrating motor 51 is connected to a transmission block 54, a keyway 55 is provided on the transmission block 54, a connecting sleeve 56 is connected to the transmission block 54, and the filter barrel 5 includes a central shaft 53, which is threadedly connected to the connecting sleeve 56. The filter barrel 5 is installed on the dust-vibrating motor 51 assembly through the mounting flange 32, the transmission block 54 is connected to the connecting sleeve 56 through a flat key, and the dust-vibrating motor 51 transmits power to the filter barrel 5 through the flat key of the transmission block 54 and the thread of the connecting sleeve 56, wherein the rotational power direction of the dust-vibrating motor 51 is the reverse thread direction of the connecting sleeve 56, and will not cause the connection failure of the connecting sleeve 56. The dust-vibrating motor 51 is located outside the dust collecting box 3, which is convenient for installation and wiring harness connection. The dust-vibrating motor 51 transmits power through the transmission block 54 and the connecting sleeve 56, which is convenient for disassembly and maintenance.

[0037] like Figure 4 As shown, the dust collecting box 3 is provided with an external air duct quick connector 33, and the external air duct quick connector 33 is connected with a high-pressure dust blowing pipe 34, and the high-pressure dust blowing pipe 34 is located in the dust collecting box 3, and the open end of the high-pressure dust blowing pipe 34 faces the end of the dust-vibrating scraper 52. The dust collecting box 3 is connected to the dust blowing system through the quick connector, and the high-pressure dust blowing pipe 34 forms a plurality of dust blowing channels through two three-way interfaces 35 in sequence, so that each dust blowing channel is arranged near each dust-vibrating scraper 52. When the dust-vibrating motor 51 is working, the dust blowing system blows dust into the dust collecting box 3, and cooperates with the continuous vibration of the dust-vibrating scraper 52 to effectively improve the cleaning effect of the filter barrel 5.

[0038] like Figure 4 As shown, the end of the mounting plate 57 is connected to one end of the dust box 3 with a bakelite handle 58, and a handle 59 is provided on the mounting plate 57. Assembly method of the filter barrel 5: the filter barrel 5 is mounted on the dust-vibrating motor 51 assembly through the mounting flange 32. After the overall installation, it is inserted into the dust box 3 and fixed with the bakelite handle 58. The dust box 3 is equipped with an external air duct quick connector 33 and a dust-vibrating scraper 52 to ensure a good dust-vibrating effect.

[0039] like Figure 8 As shown, a water baffle 31 is provided in the dust box 3, and the water baffle 31 is located between the filter barrel 5 and the dust box 4, and the water baffle 31 is inclined. The filter barrel 5 is made of waterproof material, and the dust box 3 is equipped with a waterproof plate, which can effectively prevent water from entering the filter barrel 5. The double-layer protection ensures that the sweeper will not be blocked and fail when cleaning the filter barrel 5 on rainy days or when there is water on the ground. Compared with the existing technology, it has better applicability and is suitable for multiple scenes and complex environments.

[0040] like Figure 6As shown, a maintenance cover 25 is detachably connected to the top of the dust suction chamber 22, and the dust suction fans 21 are arranged in pairs, with a partition 26 arranged between the dust suction fans 21. The maintenance cover 25 is installed on the rear top plate 2 of the cab by multiple bolts to form a closure for the dust suction chamber 22. The synchronous use of the two dust suction fans 21 improves the air suction effect. A partition 26 is arranged between the two dust suction fans 21 so that the exhaust ports of the two dust suction fans 21 correspond to the two sides of the vehicle body respectively, thereby preventing the exhaust airflows of the two dust suction fans 21 from interfering with each other.

[0041] like Figure 5-1 and Figure 5-2 As shown, a cross guide plate 24 is provided at the bottom open end of the air suction bellows 23, and the bottom open end of the air suction bellows 23 and the cross guide plate 24 extend into the filter barrel 5. A cross guide plate 24 is provided at the bottom end of the air suction bellows 23, and the cross guide plate 24 extends into the filter barrel 5. The bottom end of the air suction bellows 23 extends into the filter barrel 5 to form a sealed connection. The cross guide plate 24 can play a guiding and positioning role when the filter barrel 5 is installed, ensuring the concentricity of the filter barrel 5 and facilitating installation. At the same time, the cross structure is designed to not affect the suction of the fan. Compared with similar products on the market, this mechanism has a more reasonable and reliable structure and is more convenient for customers to use.

[0042] A sweeper comprises the above-mentioned sweeper dust collection system.

[0043] There are three modes for cleaning the filter barrel 5:

[0044] 1. By designing a dust-vibrating scraper inside the dust collecting box 3, when the dust-vibrating motor 51 drives the filter barrel 5 to rotate, the dust-vibrating scraper will move the filter barrel 5 to achieve dust vibration.

[0045] 2. The dust collecting box 3 is equipped with an external dust blowing system. The external high-pressure air pipe is installed on the quick interface through the external air duct quick connector 33. In the first mode, dust is blown at the same time to achieve strong dust shaking, further improving the cleaning effect of the dust on the filter barrel 5.

[0046] 3. Remove the bakelite handle 58 and pull the handle 59 to remove the filter barrel 5 from the dust collecting box 3. During operation, the filter barrel 5 can be pulled out as a whole for deep cleaning without the help of tools.

[0047] The functional principle of the system is as follows: During cleaning, the motor assembly of the dust suction fan 21 operates. The high-speed rotating fan evacuates the cavity of the air suction fan to form a negative pressure. The air suction bellows 23 is hermetically connected to the dust collection box 3 to achieve the function of air suction through the air duct conversion. After the dust follows the airflow into the dust collection box 3, it adheres to the filter barrel 5 to achieve the function of dust filtration. The assembly of the dust shaking motor 51 rotates to drive the filter barrel 5 to rotate. Through the dust shaking blade 52, it scrapes on the filter barrel 5 to make the filter paper vibrate, shaking off the dust adhering to the filter paper. At the same time, an external high-pressure air duct is connected to blow dust on the filter barrel 5 to achieve a better dust blowing effect and realize the dust shaking of the filter barrel 5.

[0048] When the filter barrel 5 needs to be replaced, first remove the bakelite handle 58 and the plug of the dust shaking motor 51. The operator holds the two handles 59 with both hands and pulls outwards, and then separates the mounting flange 32 of the filter barrel 5. The installation is the reverse operation, realizing the quick disassembly function of the filter barrel 5.

[0049] The dust collection system of this sweeper has functions such as air suction, dust filtration, high-pressure dust shaking of the filter barrel 5, and quick disassembly of the filter barrel 5. It has the advantages of stable and reliable structure, easy operation, and simple maintenance. Compared with existing similar products on the market, the filter barrel 5 is not easily blocked and is also convenient to clean. The quick disassembly mechanism of the filter barrel 5 is easy to operate and more user-friendly. The effective life of the filter barrel 5 is extended by 2 - 3 times. The filtering effect is thorough and the efficiency is high, solving the problem of large dust emission; it can also adapt to the cleaning environment in rainy days or when the ground is wet. The design layout of the dust suction system is reasonable and the operation is reliable, which can effectively reduce the secondary pollution of dust.

[0050] The above has described the present invention exemplarily in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited by the above methods. As long as various non-substantive improvements are made by adopting the method concept and technical solution of the present invention; or without improvement, the above concept and technical solution of the present invention are directly applied to other occasions, all are within the protection scope of the present invention.
