Description

Technical Field

[0001] This application relates to the technical field of road cleaning accessories, and particularly to a dust suction port applicable to a high-speed road sweeper. Background Art

[0002] With the continuous development of urban technology and economy, road sweepers have gradually replaced manual road cleaning operations. The dust suction port in a road sweeper plays an important role in garbage collection. However, most of the existing dust suction ports of road sweepers are circular. During the cleaning process, since the center position of the circular suction port is far from the edge, the air flow velocity at the center of the circular suction port is small and the negative pressure is insufficient. Therefore, dust and particulate garbage cannot be completely sucked clean. This problem is particularly obvious when the road sweeper is running at high speed, resulting in slow cleaning speed, low efficiency, time-consuming, energy-consuming, and poor cleaning effect of the road sweeper. Therefore, it is necessary to improve the structure of the dust suction port to optimize the garbage cleaning efficiency and cleaning effect. Summary of the Invention

[0003] In order to solve the problems of unreasonable design of the existing dust suction port, time-consuming and energy-consuming during cleaning, and poor cleaning effect, this application provides a dust suction port applicable to a high-speed road sweeper.

[0004] The dust suction port applicable to a high-speed road sweeper provided by this application adopts the following technical solutions:

[0005] A dust suction port applicable to a high-speed road sweeper, comprising:

[0006] A circular suction pipe, the top end of the circular suction pipe is used for fixedly communicating with the dust collection box of the road sweeper;

[0007] A suction port body, the suction port body is integrally connected to the bottom end of the circular suction pipe. The suction port body is provided with a front-section suction port at the side front, and the suction port body is provided with a rear-section suction port at the bottom. The rear-section suction port is set as a triangle with a gradually increasing width along the traveling direction of the road sweeper;

[0008] A plurality of rubber baffles are symmetrically arranged on both sides of the rear-section suction port of the suction port body. The rubber baffles are fixedly connected to the suction port body, and the included angle between a pair of symmetric rubber baffles is greater than the end included angle of the rear-section suction port.

[0009] Optionally, the distance between the horizontal plane at the bottom end of the suction port body and the ground is 5 mm - 15 mm.

[0010] Optionally, a steel shovel guide plate is fixedly connected to the bottom of the front-section suction port of the suction port body, and the included angle between the steel shovel guide plate and the ground is 30° - 70°.

[0011] Optionally, a rubber shovel guide plate is fixedly connected to the center of the rear-section suction port of the suction port body along the length direction, and the included angle between the rubber shovel guide plate and the ground is 30° - 70°.

[0012] Optionally, a mounting seat is fixedly connected above the front suction port of the suction port body, and the mounting seat is used for being hinged at the connection part with the road sweeper.

[0013] Optionally, four rubber baffles are symmetrically arranged on both sides of the rear suction port of the suction port body, and the distance between two rubber baffles on the same side of the rear suction port is 5-10 cm.

[0014] Optionally, inclined baffles are integrally and fixedly connected to both sides of the front suction port of the suction port body, and the inclined baffles are used for guiding and gathering the garbage to the front suction port.

[0015] In summary, the present application includes at least one of the following beneficial technical effects:

[0016] 1. High-efficiency dust suction and garbage gathering: The designed front suction port and rear suction port, through the cooperation of the steel shovel guide plate and the inclined baffle of the front suction port, effectively shovel up and guide the garbage in front into the suction port, improving the concentration and efficiency of dust suction. The rear suction port adopts a triangular design with a gradually increasing width, which can better adapt to the garbage that may be missed by the front suction port during the cleaning process and the uneven distribution of garbage. At the same time, the rubber baffles on both sides of the rear suction port guide and gather the missed garbage into the rear suction port, further improving the dust suction efficiency.

[0017] 2. Enhanced sealing and reduced air leakage: The rubber baffle not only plays a role in guiding and gathering the garbage, but also enhances the sealing of the dust suction port and reduces the air leakage phenomenon. This design helps to form a stronger negative pressure at the rear suction port, thereby improving the dust suction effect and ensuring that the garbage can be more thoroughly sucked into the dust suction port.

[0022] The following further describes the present application in conjunction with Figure 1 and Figure 2 the attached drawings.

[0023] An embodiment of the present application discloses a suction port applicable to a high-speed sweeper. Referring to Figure 1 and Figure 2 , a suction port applicable to a high-speed sweeper includes a circular suction pipe 1, a suction port body 2, a rubber baffle 3, a steel shovel guide plate 4, a rubber shovel guide plate 5, a mounting seat 6 and an inclined baffle 7.

[0024] Referring to Figure 1 and Figure 2 , the circular suction pipe 1 is vertically arranged, and the top end of the circular suction pipe 1 is used for fixedly communicating with the dust collection box of the sweeper, serving as the main channel for dust suction.

[0025] Referring to Figure 1 and Figure 2 , the suction port body 2 is integrally connected to the bottom end of the circular suction pipe 1 to form the main body part of the suction port. The distance between the horizontal plane at the bottom end of the suction port body 2 and the ground is designed to be 5 mm - 15 mm, ensuring that the suction port keeps appropriate contact with the ground, neither being too close to cause wear nor being too high to affect the dust suction effect.

[0026] Referring to Figure 1 and Figure 2 , the suction port body 2 is provided with a front-section suction port 21 at the front side for sucking the garbage near the front side of the sweeper; a rear-section suction port 22 is provided at the bottom, and the rear-section suction port 22 is designed as a triangle with a gradually increasing width along the traveling direction of the sweeper, so as to better adapt to the situation of garbage omission at the front-section suction port 21 and uneven garbage distribution during the sweeping process.

[0027] Referring to Figure 1 and Figure 2 , a steel shovel guide plate 4 is fixedly connected to the bottom of the front-section suction port 21, and the included angle between the steel shovel guide plate 4 and the ground is 30° - 70°, which is used to shovel up the garbage in front and guide it to the front-section suction port 21 to improve the dust suction efficiency. The steel shovel guide plate 4 has good hardness and rigidity, so as to avoid hard garbage from damaging the dust suction body or the steel shovel guide plate 4. The inclined baffles 7 are integrally and fixedly connected to both sides of the suction port body 2 at the front-section suction port 21, and these inclined baffles 7 are used to guide and gather the garbage to the front-section suction port 21 to improve the concentration and efficiency of dust suction.

[0028] Referring to Figure 1 andFigure 2 , on both sides of the rear suction port 22, a plurality of rubber baffles 3 are symmetrically arranged and fixedly connected to the suction port body 2. The included angle between these rubber baffles 3 is greater than the end included angle of the rear suction port 22, which can effectively guide and gather the garbage missed by the front suction port 21 into the rear suction port 22, thus avoiding the problem that the garbage cannot be completely sucked due to the long distance from the suction port. At the same time, it increases the sealing performance of the suction port, reduces air leakage, and enhances the negative pressure at the rear suction port 22.

[0029] Refer to Figure 1 and Figure 2 , at the center of the rear suction port 22 along the length direction, a rubber shovel guide plate 5 is fixedly connected. The included angle between the rubber shovel guide plate 5 and the ground is also 30° - 70°, which is used to further shovel up the garbage behind and guide it to the rear suction port 22. At the same time, its elasticity reduces the friction and wear with the ground.

[0030] Refer to Figure 1 and Figure 2 , on the suction port body 2 above the front suction port 21, a mounting seat 6 is fixedly connected. The mounting seat 6 is used for hinged connection at the connection with the sweeper, so that the suction port can be adjusted according to needs to adapt to different cleaning scenarios and ground conditions. When there are road spikes on the road, when the road spikes collide with the steel shovel guide plate 4, the suction port body 2 is instantly flipped by rotating the mounting seat 6, which plays a role in protecting the suction port body 2, thus solving the problem of cleaning road spikes.

[0031] The implementation principle of the suction port applicable to a high-speed sweeper in this application embodiment is as follows: The suction port applicable to a high-speed sweeper in this application embodiment is designed by fully considering various challenges faced by the sweeper in actual operation, such as uneven garbage distribution, uneven ground, road spikes and other obstacles. Through a series of ingenious structural designs, efficient and stable dust suction effects are achieved.

[0032] First of all, the circular suction pipe 1, as the main channel for dust suction, is vertically arranged and fixedly connected to the dust collection box of the sweeper, ensuring the smooth and efficient air flow during the dust suction process. The suction port body 2 is integrally connected to the bottom end of the circular suction pipe 1 to form a sturdy and durable suction port main body. The horizontal plane at the bottom end of the suction port body 2 is kept at a distance of 5 mm - 15 mm from the ground. This design not only avoids the wear caused by the direct contact between the suction port and the ground, but also ensures that the suction port can closely adhere to the ground to effectively suck in garbage.

[0033] The front suction port 21 and the rear suction port 22 on the suction port body 2 suck in garbage in different areas respectively. Through the cooperation of the steel shovel guide plate 4 and the inclined baffle 7, the front suction port 21 shovels up the garbage in front and guides it into the suction port, improving the concentration and efficiency of dust collection. The hardness and rigidity design of the steel shovel guide plate 4 ensure that it can effectively handle hard-textured garbage and avoid damaging the dust collection body or the steel shovel guide plate 4 itself.

[0034] The design of the rear suction port 22 is more flexible and efficient. Its triangular shape gradually increases in width along the traveling direction of the sweeper, enabling it to better adapt to the garbage that may be missed by the front suction port 21 during the cleaning process and the uneven distribution of garbage. The rubber baffles 3 on both sides of the rear suction port 22 not only play a role in guiding and gathering the garbage, but also enhance the sealing performance of the suction port, reducing air leakage, thereby enhancing the negative pressure at the rear suction port 22 and improving the dust collection effect. According to the flow formula: flow = flow velocity × area, the area of this triangular suction port is 76% of the area of the circular suction port. That is, at the same flow rate, the flow velocity of this triangular suction port is 130% of the flow velocity of the circular suction port. According to the actual measurement; when the flow rates are the same, the wind speed at the edge of the suction port is the highest, and the wind speed at the center of the circular suction port is the lowest, and this is also the place where the most dust and particulate garbage are located. The two triangular sides of the triangular suction port go from the front section to the rear section to the middle of the suction port, making the flow velocity of the entire suction port in a high-flow state.

[0035] The design of the rubber shovel guide plate 5 further improves the dust collection ability of the rear suction port 22. Its elastic material reduces the friction and wear with the ground, and at the same time, the included angle with the ground is designed to be 30° - 70°, enabling the shoveled garbage to be smoothly sucked into the rear suction port 22.

[0036] The design of the mounting seat 6 gives the suction port more flexibility. Through the hinge connection at the joint with the sweeper, the suction port can be adjusted according to needs to adapt to different cleaning scenarios and ground conditions. In particular, when encountering obstacles such as road spikes, when the road spikes collide with the steel shovel guide plate 4, the hinge design of the mounting seat 6 enables the suction port body 2 to instantly flip, thereby protecting the suction port body 2 from damage and solving the problem of cleaning road spikes.

[0037] In summary, the suction port applicable to a high-speed sweeper in the embodiments of the present application achieves efficient, stable, and flexible dust collection effects through reasonable design and optimization, providing a strong guarantee for the operation efficiency and cleaning quality of the sweeper.

[0038] The above are all preferred embodiments of the present application. The protection scope of the present application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
