DETAILED DESCRIPTION

[0025] To make the objectives, technical solutions, and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail below. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other implementations obtained by those of ordinary skill in the art without inventive effort are within the scope of protection of the present invention.

[0026] The terms "first," "second," and the like in the specification and claims of this application are used to distinguish similar objects, and are not used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of this application can be implemented in an order other than that illustrated or described herein, and that the objects distinguished by "first," "second," and the like are generally of the same type, and do not limit the number of objects; for example, the first object can be one or more. In addition, the term "and / or" in the specification and claims refers to at least one of the connected objects, and the character " / " generally indicates that the objects connected are in an "or" relationship.

[0027] The following is combined with Figures 1 to 11 , the sanitation vehicle provided in the embodiment of the present application is described in detail through specific embodiments and application scenarios.

[0028] Reference Figures 1 to 11 An embodiment of the present application discloses a sanitation vehicle, which includes a tank body 100 and a filter silo 200.

[0029] The tank body 100 is a basic component of the sanitation vehicle and can store garbage swept by the sanitation vehicle. Specifically, the sanitation vehicle further comprises a suction pipe 1100 connected with the tank body 100, a first end of the suction pipe 1100 is located outside the tank body 100, and a second end of the suction pipe 1100 is located inside the tank body 100. Under the action of a fan of the sanitation vehicle, the suction pipe 1100 can suck garbage existing in an external environment into the tank body 100 for collection.

[0030] In the embodiment of the present application, a partition plate 110 is arranged in the tank body 100, the partition plate 110 divides the tank body 100 into a first bin 120 and a second bin 130, the first bin 120 is located above the second bin 130, the first end of the suction pipe is located in the first bin 120, the first bin 120 is used for collecting garbage with a larger size, such as branches, leaves and garbage bags, and the second bin 130 is used for collecting dust. That is, in this paper, the first bin 120 is used for collecting garbage with a larger size, and the second bin 130 is used for collecting dust with a smaller size.

[0031] In the embodiment of the present application, the sanitation vehicle has a dry sweeping air duct and a wet sweeping air duct, the dry sweeping air duct and the wet sweeping air duct are connected with the first bin 120 respectively, a dry-wet switching device is arranged between the dry sweeping air duct and the wet sweeping air duct, the dry-wet switching device can switch the sweeping mode of the sanitation vehicle, in the dry sweeping mode, the dry sweeping air duct is conducted, and in the wet sweeping mode, the wet sweeping air duct is conducted. The first bin 120 is provided with a filter screen 1200, the filter screen 1200 is located at the connection position of the first bin 120, the dry sweeping air duct and the wet sweeping air duct, the filter screen 1200 can intercept garbage with a larger size, so as to keep it in the first bin 120, so as to realize garbage collection and avoid garbage with a larger size from entering the dry sweeping air duct or the wet sweeping air duct to affect the normal sweeping of the sanitation vehicle.

[0032] A filter cartridge 210 and a guide plate 220 are provided in the filter cartridge silo 200. The guide plate 220 is located below the filter cartridge 210. The guide plate 220 is inclined relative to the bottom wall of the tank body 100. The two oppositely arranged guide plates 220 form an ash hopper in the tank body 100, and the ash hopper is connected to the second bin 130. When the sanitation vehicle is performing dry sweeping operations, the dust carried by the dry sweeping airflow first enters the first bin 120 through the suction pipe, and then flows through the dry sweeping air duct through the filter screen 1200 and is intercepted by the filter cartridge 210 in the filter cartridge silo 200. Part of the dust settles on the guide plate 220 and slides down to the second bin 130 connected to the guide plate 220 under the action of gravity. When the sanitation vehicle is in dry sweeping mode, the airflow generated by the fan can enable the suction pipe 1100 to introduce external dust into the first bin 120, and the dust-laden airflow can pass through the filter 1200 into the filter cartridge bin 200. The filter cartridge bin 200 is used to remove dust from the dust-laden airflow. The air inlet of the filter cartridge bin 200 is located between the filter cartridge 210 and the guide plate 220. The dust accumulated on the guide plate 220 can be blown into the second bin 130, which can prevent dust from accumulating and adhering to the guide plate 220, thereby making it easy to discharge the dust in the filter cartridge bin 200.

[0033] In the sanitation vehicle of the embodiment of the present application, when the sanitation vehicle is in dry sweeping mode, dry dust-laden air flows into the filter cartridge silo 200 through the air inlet 230 between the filter cartridge 210 and the guide plate 220, which not only brings dust into the filter cartridge silo 200, but also blows the dust accumulated on the guide plate 220 toward the second silo 130, making it difficult for the dust to adhere to the guide plate 220, thereby making it easy for the dust in the filter cartridge silo 200 to be discharged into the second silo 130, thereby facilitating dust discharge by the sanitation vehicle.

[0034] In the embodiment of the present application, a water tank 300 is provided in the second bin 130, and the water tank 300 is used to store clean water to facilitate the cleaning operation of the sanitation vehicle. The two oppositely arranged water tanks 300 form an ash discharge channel 140 at the bottom of the second bin 130. The ash discharge channel 140 has a first end and a second end. The first end of the ash discharge channel 140 extends to the ash hopper, and the second end of the ash discharge channel 140 extends to the ash discharge port 150 of the second bin 130. The ash discharge port 150 is located at the rear end of the sanitation vehicle; The first end of the ash discharge channel 140 is connected to the lower end of the ash hopper, which can make the dust easily enriched in the ash discharge channel 140 and finally discharged from the ash discharge port 150. The water tank 300 occupies the space on both sides of the ash discharge channel 140, avoiding the dust falling through the ash hopper from being distributed in the entire second bin 130 and not easily discharged from the ash discharge port 150. At the same time, the layout of arranging the ash discharge channel 140 in the middle and the water tanks 300 on both sides can improve the compactness of the layout of the second bin 130.

[0035] In an embodiment of the present application, the ash discharge port 150 is provided with a first door body 400, which is rotatably connected to the tank body 100, and the rotation axis of the first door body 400 is perpendicular to the vertical direction; under such a setting, the first door body 400 can be in a vertical state or rest against the tank body 100 under the action of its own gravity. In the process of the sanitation vehicle dumping the accumulated ash, the tank body 100 rotates relative to the first door body 400 to make the first door body 400 in an open state, and the accumulated ash in the ash discharge channel 140 is discharged through the ash discharge port 150. That is to say, the first door body 400 can be opened or closed relative to the tank body 100 by relying on its own gravity, without the need to connect a separate driving mechanism, which simplifies the structure of the sanitation vehicle and is cleverly designed.

[0036] As can be seen from the above, the first door body 400 can be in a vertical state or a state against the tank body 100 by relying on its own gravity. Therefore, when the sanitation vehicle shakes, the first door body 400 may swing open, causing humid airflow or sewage in the external environment to enter the dust discharge channel 140 and cause the accumulated dust to become damp and sticky or agglomerated, which is not conducive to the smooth discharge of dust. This false triggering situation will also be detrimental to the cleaning work.

[0037] In a further technical solution, the first bin 120 has a garbage outlet 160, which is provided with a second door 500. When the second door 500 is in the open state, larger garbage in the first bin 120 can be discharged from the garbage outlet 160. In this embodiment of the present application, the second door 500 is connected to a first drive mechanism 600, which can drive the second door 500 to switch between an open state and a closed state. When the second door 500 is in the closed state, the second door 500 and the first door 400 are offset. In other words, when the second door 500 is closed, the first door 400 is also closed, and the second door 500 can compress and shield the first door 400, forming a double-layer door at the ash discharge port 150 of the tank body 100. This can prevent external moist airflow or sewage from splashing into the ash discharge channel 140, and prevent dust in the second bin 130 from getting wet and sticking or clumping.

[0038] In the embodiment of the present application, the first driving mechanism 600 can be a cylinder, the cylinder sleeve of the cylinder is hinged to the tank body 100, and the piston rod of the cylinder is hinged to the second door body 500 to drive the second door body 500 to open or close. Of course, in addition to using a cylinder, the first driving mechanism 600 can also be a pneumatic cylinder or an electric telescopic mechanism, etc., as long as it can drive the opening and closing of the second door body 500. The embodiment of the present application does not limit the specific form of the first driving mechanism 600.

[0039] The second door body 500 is provided with a first sealing gasket 700 on the side facing the first door body 400. The first sealing gasket 700 has a first sealing area and a second sealing area. When the second door body 500 is in a closed state, the garbage outlet 160 is located in the first sealing area, and the ash discharge port 150 is located in the second sealing area. In an optional embodiment, the first sealing gasket 700 is in a Japanese-shaped configuration, with the upper area of ​​the first sealing gasket 700 being the first sealing area and the lower area of ​​the first sealing gasket 700 being the second sealing area. With such a configuration, when the second door body 500 is in a closed state, the first sealing gasket 700 fits tightly with the tank body 100, ensuring both the sealing between the garbage outlet 160 and the ash discharge port 150 and the external environment, and the sealing between the garbage outlet 160 and the ash discharge port 150, thereby preventing the sewage in the first bin 120 from overflowing into the second bin 130 through the garbage outlet 160 and the ash discharge port 150.

[0040] In a further technical solution, the ash discharge port 150 is also provided with a second sealing gasket. When the first door body 400 is in a closed state, the first door body 400 and the second sealing gasket are sealed together to further enhance the sealing of the second bin 130. That is to say, during wet sweeping operations and the second door body 500 is closed, the ash discharge port 150 of the second bin 130 adopts a double-layer seal, which can effectively prevent external sewage or humid airflow from entering the second bin 130.

[0041] In the embodiment of the present application, the dry-wet switching device 800 includes a bracket 810, a third door 820, a fourth door 830, and a second drive mechanism 840. The bracket 810 is the basic component of the dry-wet switching device and can provide a mounting base for the third door 820, the fourth door 830, and the second drive mechanism 840. Specifically, the bracket 810 has a dry-sweep air duct and a wet-sweep air duct. The third door 820 is located in the wet-sweep air duct and is rotatably connected to the bracket 810, thereby switching between an open state and a closed state to open and close the wet-sweep air duct. The fourth door 830 is located in the dry-sweep air duct and can be specifically located at the air outlet of the filter cartridge silo 200. The fourth door 830 is rotatably connected to the bracket 810, thereby switching between an open state and a closed state to open and close the dry-sweep air duct.

[0042] In an embodiment of the present application, the third door body 820 rotates around the first axis relative to the bracket 810, and the second driving mechanism 840 is connected to the third door body 820. The second driving mechanism 840 can drive the third door body 820 to rotate around the first axis, thereby switching the third door body 820 between an open state and a closed state.

[0043] The fourth door body 830 rotates relative to the bracket 810 around a second axis, and the second axis intersects or is not in the same plane as the first axis. In an optional embodiment, the first axis is perpendicular to the second axis. The third door body 820 is provided with an extrusion member. When the third door body 820 is in a closed state, the extrusion member is separated from the fourth door body 830, and the fourth door body 830 can be in an open state under the negative pressure of the sanitation vehicle's fan; when the second drive mechanism 840 drives the third door body 820 to switch from a closed state to an open state, the opening direction of the third door body 820 interferes with the opening direction of the fourth door body 830, and the two cannot open together. At this time, the extrusion member and the fourth door body 830 are opposed, and the fourth door body 830 is pushed to switch from an open state to a closed state.

[0044] When the wet / dry sanitation vehicle is performing wet sweeping operations, the third door 820 located in the wet sweeping duct is opened, and the fourth door 830 located in the dry sweeping duct is closed. The moist airflow flows through the wet sweeping duct under the negative pressure of the fan. When the wet / dry sanitation vehicle is performing dry sweeping operations, the third door 820 located in the wet sweeping duct is closed, and the fourth door 830 located in the dry sweeping duct is opened. The dry airflow flows through the dry sweeping duct under the action of the fan and filters dust through the filter cartridges 210 within the filter silo 200. The opening and closing states of the third door 820 and the fourth door 830 are opposite, ensuring a tight seal between the dry and wet sweeping ducts during both dry and wet sweeping operations. This prevents moist airflow from entering the filter silo 200 and wetting the filter cartridges 210 during wet sweeping operations, which could reduce or even render the filter cartridges 210 ineffective, thereby extending the service life of the filter cartridges 210 within the filter silo 200.

[0045] In an embodiment of the present application, the third door body 820 has a first shaft 821, and the third door body 820 is connected to the bracket 810 for rotation through the first shaft 821. The second driving mechanism 840 includes a first driving member 841 and a first crank 842. The first crank 842 includes an axis 8421 and a handle 8422. The first driving member 841 is connected to the handle 8422, and the first axis 821 is connected to the axis 8421. Under such a setting, the first driving member 841 drives the first crank 842 to swing, which can drive the first shaft 821 to rotate; at the same time, the shaft portion 8421 of the first crank 842 can compensate for the axial length of the first shaft 821. In the axial direction of the first shaft 821, the length of the first shaft 821 can be less than or equal to the width of the third door body 820, so that when the third door body 820 is installed, the first shaft 821 will not easily interfere with the bracket 810 because its length is greater than the width of the third door body 820, thereby improving the convenience of installation of the third door body 820.

[0046] In the first shaft 821 and the shaft portion 8421, one is provided with a first limiting portion, and the other is provided with a second limiting portion. In the circumferential direction of the first shaft 821, the first limiting portion and the second limiting portion are limited and matched. Figure 1 The first limiting portion can be a first protrusion provided at the end of the first shaft 821, and a first recess is formed between the first protrusion and the first shaft 821. The second limiting portion can be a second protrusion provided at the shaft portion 8421, and a second recess is formed between the second protrusion and the shaft portion 8421. When the first shaft 821 and the shaft portion 8421 are connected to each other, the first protrusion and the second protrusion are staggered, the first protrusion is located in the second recess, and the second protrusion is located in the first recess. The first protrusion and the second protrusion can both be semi-cylindrical, which can ensure that the shaft portion 8421 and the first shaft 821 transmit torque evenly.

[0047] In a further technical solution, the dry-wet switching device also includes a locking member 870, the first limiting portion is provided with a first through hole, the second limiting portion is provided with a second through hole, and the locking member 870 is passed through the first through hole and the second through hole; in this case, based on the existence of the locking member 870, the locking member 870 can limit the relative movement of the first shaft 821 and the shaft portion 8421 in the axial direction, thereby preventing the first crank 842 from separating from the first shaft 821.

[0048] In an optional embodiment, the extrusion member includes a protrusion (not shown in the figure) provided on the third door body 820. During the process of switching the third door body 820 from a closed state to an open state, the protrusion slides with the fourth door body 830 and pushes the fourth door body 830 to switch from an open state to a closed state.

[0049] In another optional embodiment, the extrusion member includes a roller 850, the third door body 820 is fixedly provided with a mounting frame 860, the roller 850 is rotatably provided on the mounting frame 860, and the roller 850 is arranged adjacent to the fourth door body 830. During the process of switching the third door body 820 from a closed state to an open state, the roller 850 and the fourth door body 830 roll together; in this case, when the third door body 820 switches from a closed state to an open state, the roller 850 and the fourth door body 830 roll together, which can prevent the extrusion member and the fourth door body 830 from sliding relative to each other and scratching the fourth door body 830. At the same time, the rolling cooperation of the roller 850 and the fourth door body 830 can suppress the generation of noise.

[0050] The dry-wet switching device also includes a third sealing gasket 880 and a fourth sealing gasket 890. The third sealing gasket 880 is arranged on the bracket 810. When the third door body 820 is in a closed state, the third door body 820 and the third sealing gasket 880 are sealed together. Based on the existence of the third sealing gasket 880, when the third door body 820 is in a closed state, the third sealing gasket 880 can prevent the dry airflow in the dry sweep air duct from entering the wet sweep air duct through the assembly gap between the third door body 820 and the bracket 810, thereby preventing the dust-laden airflow from passing through the filtering effect of the filter cartridge 210.

[0051] The dry-wet switching device also includes a fourth sealing gasket 890, which is arranged on the bracket 810. When the fourth door body 830 is in a closed state, the fourth door body 830 and the fourth sealing gasket 890 are sealed together; under such a setting, when the fourth door body 830 is in a closed state, the fourth sealing gasket 890 can prevent the humid airflow in the wet sweeping air duct from entering the dry sweeping channel through the assembly gap between the fourth door body 830 and the bracket 810, thereby preventing the humid airflow from wetting the filter cartridge in the filter cartridge silo 200, causing the filter cartridge cleaning function to be reduced or ineffective.

[0052] In a further technical solution, the sanitation vehicle of the embodiment of the present application also includes a fifth door body 900 and a third drive mechanism 1000. The fifth door body 900 is arranged in the dry sweeping air duct. In the direction of airflow in the dry sweeping air duct, the fifth door body 900 is arranged at the front end of the filter silo 200. The fifth door body 900 has an open state and a closed state. The third drive mechanism 1000 is connected to the fifth door body 900. The third drive mechanism 1000 can drive the fifth door body 900 to switch between the open state and the closed state. Under such configuration, a fifth door body 900 is provided at the front end of the air inlet of the filter cartridge silo 200, and a fourth door body 830 is provided at the air outlet of the filter cartridge silo 200. When the sanitation vehicle performs wet sweeping operations, the second drive mechanism 840 drives the third door body 820 to open and the fourth door body 830 to close, and the third drive mechanism 1000 drives the fifth door body 900 to close, which can simultaneously play a sealing role at the air inlet and air outlet of the filter cartridge silo 200, preventing humid airflow from entering the filter cartridge silo 200 through the front end or rear end of the filter cartridge silo 200, further ensuring the sealing of the filter cartridge silo 200 during the wet sweeping operations of the sanitation vehicle, and preventing humid airflow from wetting the filter cartridge 210 in the filter cartridge silo 200.

[0053] Similarly, in the present embodiment, the third driving mechanism 1000 can include a second driving member 1010 and a second crank 1020, the second driving member 1010 is arranged on the support 810 and connected with the second crank 1020, the second crank 1020 is connected with the rotating shaft of the fifth door body 900, has the characteristics of compact structure, large power transmission and high reliability, the second driving member 1010 can be an oil cylinder, an air cylinder or an electric push rod, and the present embodiment does not limit the specific form of the second driving member 1010.
