Description

Technical Field

[0001] This application relates to the field of sanitation vehicle technology, and in particular to a garbage bin and a sweeper truck. Background Technology

[0002] A sweeper truck is a specialized vehicle designed for cleaning city roads, squares, and other large areas. It integrates sweeping and washing functions, effectively removing garbage, dust, and stubborn stains, maintaining the cleanliness and aesthetics of public areas. The dry-cleaning sweeper truck combines dry sweeping (vacuuming) and wet cleaning (spraying and scrubbing) functions, allowing users to select the appropriate operating mode based on their needs.

[0003] The dry cleaning and sweeping vehicle can adopt a two-tiered garbage bin design. Large items and wet garbage are placed in the upper bin, while dry garbage such as dust is placed in the lower bin. Currently, the upper and lower bins are sealed with the same rear door, mainly relying on the sealing strips around the perimeter for tightness. However, the middle partition is prone to not closing tightly due to aging, residue accumulation, assembly errors, etc., causing wastewater from the upper bin to flow into the lower dry space, contaminating the garbage chamber and internal filters in the lower dry area.

[0058] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0059] refer to Figure 1 and Figure 2 This application discloses a trash can 100, which includes a can body 110, an upper rear door 120, a lower rear door 130, an upper locking mechanism 140, and a lower locking mechanism 150.

[0060] The container 110 has an upper waste chamber 111 and a lower waste chamber 112;

[0061] The upper rear door 120 and the lower rear door 130 are movably installed in the container 110. The upper rear door 120 is used to open or close the unloading port of the upper garbage chamber 111, and the lower rear door 130 is used to open or close the unloading port of the lower garbage chamber 112.

[0062] The upper locking mechanism 140 is used to press the upper rear door 120 against the housing 110;

[0063] The lower locking mechanism 150 is used to press the lower rear door 130 against the housing 110.

[0064] As described above, by providing movable upper rear door 120 and lower rear door 130 on the container 110, the upper rear door 120 and lower rear door 130 can be controlled independently to open or close the unloading ports of the upper and lower garbage chambers 112. At the same time, after the upper garbage chamber 111 and the lower garbage chamber 112 are closed, the upper locking mechanism 140 can close the upper rear door 120, and the lower locking mechanism 150 can close the lower rear door 130. This effectively closes and seals the upper and lower garbage chambers respectively, preventing garbage from the upper garbage chamber 111 from flowing into the lower garbage chamber 112.

[0065] In this embodiment, the upper rear door 120 and the lower rear door 130 can be closed by means of a locking hook.

[0066] Specifically, continue to refer to Figure 2 and Figure 3 The upper locking mechanism 140 includes an upper locking hook 141, which includes a connected upper hinge section 1411 and an upper hook body 1410. The upper locking hook 141 can be integrally formed, so that the upper hinge section 1411 and the upper hook body 1410 are integrally connected.

[0067] The upper hinge section 1411 is hinged to the upper rear door 120. When the upper hinge section 1411 drives the upper hook body 1410 to the locked position, the upper hook body 1410 can abut against the housing 110, thereby closing the upper rear door 120. When the upper hinge section 1411 drives the upper hook body 1410 to the unlocked position, the upper hook body 1410 can separate from the housing 110, thereby releasing the upper rear door 120 so that the upper rear door 120 can be opened.

[0068] The top of the upper rear door 120 is hinged to the housing 110. The upper rear door 120 is rotated backward and upward (counterclockwise as shown in the figure) to open the unloading port of the upper garbage chamber 111 to unload the garbage in the upper garbage chamber 111. After the garbage is unloaded, the upper rear door 120 is rotated forward and clockwise to reset and close the unloading port of the upper garbage chamber 111.

[0069] A locking element 142 is provided on the container 110. The shape of the locking element 142 is not specifically limited and can be a cylinder. The locking element 142 is located below the upper garbage chamber 111 and also in front of the upper rear door 120.

[0070] The upper hinge section 1411 is a rectangular block structure. The middle part of the upper hinge section 1411 is hinged to the lower part of the upper rear door 120 and is located behind the locking member 142. The upper hook body 1410 is connected to the end of the upper hinge section 1411 near the locking member 142. When the upper hinge section 1411 is in the locked position of the upper rear door 120, the upper hook body 1410 can hook the locking member 142 and abut against the front side of the locking member 142. In this way, the upper rear door 120 is closed by hooking the locking member 142 through the upper hook 141, ensuring that the upper garbage chamber 111 is sealed.

[0071] Optionally, the upper locking mechanism 140 may also include an upper rear door telescopic component 143, a sliding shaft 145, a sliding seat 144, and a linkage rod 146;

[0072] The upper rear door telescopic component 143 can be a hydraulic cylinder or an electric push rod or other components that can provide linear driving force. One end of the upper rear door telescopic component 143 is hinged to the housing 110 and is located above the upper rear door 120.

[0073] The sliding seat 144 is fixed to the middle rear side of the upper rear door 120 and is provided with a waist-shaped hole 1440. The length direction of the waist-shaped hole 1440 is parallel to the upper rear door 120.

[0074] The other end of the upper rear door telescopic component 143 is hinged to one end of the linkage rod 146 via a sliding shaft 145;

[0075] The slide shaft 145 passes through the waist-shaped hole 1440;

[0076] The other end of the linkage rod 146 is hinged to the end of the upper hinge section 1411 away from the locking member 142.

[0077] In this way, the extension and retraction of the upper rear door telescopic component 143 can drive the upper rear door 120 to rotate relative to the container 110, thereby opening or closing the unloading port of the upper garbage chamber 111. At the same time, the extension and retraction of the upper rear door telescopic component 143 will drive the sliding shaft 145 to slide in the waist-shaped hole 1440, thereby driving the linkage rod 146 to move up and down. In this way, the linkage rod 146 will drive the upper locking hook 141 to rotate through the lever action, so as to hook the locking member 142 or separate from the locking member 142. That is, when the upper rear door telescopic component 143 is shortened, the upper hinge section 1411 drives the upper hook body 1410 to separate, and then the upper rear door 120 opens counterclockwise to unload garbage. After unloading, the upper rear door telescopic component 143 extends, and the upper hinge section 1411 drives the upper rear door 120 to rotate counterclockwise to close the unloading port of the lower garbage chamber 112. Then the upper hook body 1410 hooks the locking member 142. In summary, the upper locking mechanism 140 serves multiple functions, including driving the upper rear door 120 to rotate to open or close the upper garbage chamber 111, driving the upper locking hook 141 to rotate to lock or release the upper rear door 120, thus achieving a linkage function and reducing costs.

[0078] The hinge point of the linkage rod 146 and the upper hinge section 1411 and the upper hook 1410 are located on both sides of the hinge point between the upper hinge section 1411 and the upper rear door 120. That is, the distance between the hinge point of the linkage rod 146 and the upper hinge section 1411 and the upper hook 1410 is greater than the distance between the hinge point of the upper hinge section 1411 and the upper rear door 120 and the upper hook 1410. Thus, when the upper rear door telescopic component 143 is shortened, the upper hook 1410 and the locking component 142 separate, and then the upper rear door 120 gradually opens to the rear and upward. When the upper rear door telescopic component 143 is extended, the upper rear door 120 gradually closes to the front and downward, and then the upper hook 1410 hooks the locking component 142.

[0079] It should also be noted that in some embodiments, a separate hydraulic cylinder can be installed on the upper rear door 120 to be hinged to the linkage rod 146, or the linkage rod 146 can be omitted and directly hinged to the upper hinge section 1411, as long as the upper locking hook 141 can be rotated relative to the upper rear door 120. In the case where a separate hydraulic cylinder is set to drive the upper locking hook 141 to rotate, the hydraulic cylinder can also be hinged to the upper hinge section 1411 at a position close to the upper hook body 1410.

[0080] The upper rear door 120 can also be slidably installed on the container 110. The upper garbage compartment 111 is opened or closed by sliding the upper rear door 120 up and down. Power is provided by a drive method such as a motor-driven gear rack structure or a lead screw mechanism.

[0081] In addition, the locking hook 141 can also be hinged to the container 110 and located below the upper garbage compartment 111. A separate hydraulic cylinder is provided and hinged to the locking hook 141 to drive the locking hook 141 to rotate. In this way, the upper hook body 1410 of the locking hook 141 can hook the bottom of the upper rear door 120 and abut against the rear side of the upper rear door 120, thereby closing the upper rear door 120.

[0082] Alternatively, the upper locking mechanism 140 can also be fitted with a pin or other fasteners to the upper rear door 120 and the housing 110 to press the upper rear door 120 onto the housing 110, thus allowing for manual locking or unlocking.

[0083] refer to Figure 2 and Figure 4 In this embodiment, the lower locking mechanism 150 includes a lower locking hook 151, which includes a connected lower hinge section 1511 and a lower hook body 1510.

[0084] The lower hinge section 1511 is hinged to the housing 110. When the lower hinge section 1511 drives the lower hook body 1510 to the locked position, the lower hook body 1510 can abut against the lower rear door 130, thereby closing the lower rear door 130. When the lower hinge section 1511 drives the lower hook body 1510 to the unlocked position, the lower hook body 1510 can separate from the lower rear door 130, thereby releasing the lower rear door 130 so that the lower rear door 130 can be opened.

[0085] The top of the lower rear door 130 is hinged to the container 110; the garbage container 100 also includes a lifting telescopic component 152, which can be a hydraulic cylinder. One end of the lifting telescopic component 152 is hinged to the container 110 and located in front of the lower rear door 130, and the other end of the lifting telescopic component 152 is hinged to the middle of the lower rear door 130. When the lifting telescopic component 152 extends, it can drive the lower rear door 130 to rotate backward and upward (i.e., counterclockwise in the figure) to open the discharge port of the lower garbage chamber 112 to unload the garbage. After unloading, the lifting telescopic component 152 shortens to drive the lower rear door 130 to rotate clockwise to reset and close the discharge port of the lower garbage chamber 112.

[0086] The lower hinge section 1511 is hinged to the housing 110. Specifically, the lower hinge section 1511 includes a lower drive part 1513 and a lower hinge part 1512 connected at an angle. The lower hinge part 1512 is hinged to the housing 110 and is located below the lower rear door 130. The lower drive part 1513 extends downward and the lower hinge part 1512 extends rearward. The lower hook body 1510 is connected to the rear end of the lower hinge part 1512.

[0087] The lower hinge section 1511 can drive the lower hinge part 1512 and the lower hook body 1510 to rotate, so that the lower hook body 1510 can switch between the locked position and the unlocked position.

[0088] When the lower hinge section 1511 drives the lower hook body 1510 to the locking position, that is, when the lower hook body 1510 is in the locking position, the lower hook body 1510 can hook the bottom of the lower rear door 130 and abut against the rear side of the lower rear door 130 to close the lower rear door 130.

[0089] To enable the rotation of the lower locking hook 151, the lower locking mechanism 150 also includes a lower locking telescopic member 153. The lower locking telescopic member 153 can be a hydraulic cylinder or other components capable of providing linear driving force, such as an electric push rod. One end of the lower locking telescopic member 153 is hinged to the housing 110, and the other end of the lower locking telescopic member 153 is hinged to the lower hinge portion 1512 of the lower hinge section 1511.

[0090] Optionally, one end of the lower locking telescopic member 153 is hinged to the housing 110 at a position in front of the lower rear door 130. The hinge point of the lower hinge section 1511 and the lower locking telescopic member 153 and the lower hook body 1510 are respectively located on both sides of the hinge point of the lower hinge section 1511 and the housing 110. The distance between the hinge point of the lower locking telescopic member 153 and the lower hinge section 1511 and the lower hook body 1510 is greater than the distance between the lower hinge section 1511 and the hinge point of the housing 110 or the lower rear door 130. In this way, when the lower locking telescopic member 153 extends, it will drive the lower hook body 1510 to hook the bottom of the lower rear door 130 and abut against the rear side of the lower rear door 130 through the lever action.

[0091] Alternatively, a lifting lug can be installed on the lower side of the upper garbage compartment 111 for hinged connection of the lower locking telescopic component 153 and the lifting telescopic component 152. In this case, the lifting telescopic component 152 is hinged to the rear side of the lower rear door 130. The lower locking telescopic component 153 can also be hinged in the area between the lower hook body 1510 and the lower hinge section 1511.

[0092] Alternatively, the lower locking mechanism 150 can also be fitted with a pin or other fasteners into the lower rear door 130 and the housing 110 to press the lower rear door 130 against the housing 110, thus allowing for manual locking or unlocking.

[0093] refer to Figure 5 The lower locking mechanism 150 is located in the middle of the left and right direction of the housing 110. Lifting telescopic components 152 are distributed on the left and right sides of the lower locking mechanism 150. In this way, when the lower rear door 130 is closed by the lower locking hook 151, the force on the left and right sides is relatively even. Moreover, the synchronous extension and retraction of the lifting telescopic components 152 on the left and right sides can ensure the stability of the lower rear door 130 during the opening and closing process.

[0094] To achieve separate storage of waste in the upper waste compartment 111 and the lower waste compartment 112, in this embodiment, the housing 110 is designed with two independent, non-interfering air ducts. Specifically, refer to... Figure 2 The housing 110 has a fan housing 114, a dust removal chamber 113, a dry cleaning duct 115, and a washing duct 116.

[0095] The dust removal chamber 113 is located in front of the upper garbage chamber 111 and the lower garbage chamber 112, and the fan receiving chamber 114 is located in front of the dust removal chamber 113.

[0096] The inlet of the sweeping duct 116 and the inlet of the dry sweeping duct 115 are both connected to the dust removal chamber 113. The dust removal chamber 113 has a first outlet 1130 connected to the fan receiving chamber 114 and a second outlet 1131 connected to the lower garbage chamber 112. The outlet of the sweeping duct 116 is connected to the fan receiving chamber 114.

[0097] The trash can 100 also includes a dust filter 180, a first dry sweeping damper 160, a second dry sweeping damper 161, and a washing and sweeping damper 163.

[0098] The dust removal filter element 180 can be a filter cartridge, which is fixed inside the dust removal chamber 113.

[0099] The first dry cleaning damper 160, the second dry cleaning damper 161, and the washing damper 163 are all movably connected to the housing 110. The first dry cleaning damper 160 is used to open or close the inlet of the dry cleaning duct 115. The second dry cleaning damper 161 is located between the dust removal chamber 113 and the fan housing chamber 114, and is used to open or close the first outlet 1130. The washing damper 163 is used to open or close the inlet of the washing duct 116.

[0100] In this way, different types of waste are layered and stored within the upper waste chamber 111 and lower waste chamber 112 formed within the housing 110. The dry sweeping mode and the washing mode can be switched by opening and closing the first dry sweeping damper 160, the second dry sweeping damper 161, and the washing damper 163. In dry sweeping mode, the first and second dry sweeping dampers 160 are open and the washing damper 163 is closed. Waste enters the upper waste chamber 111 through the suction nozzle and suction cylinder 170. Some waste settles in the upper waste chamber 111 due to gravity, while the remaining waste is carried by the airflow through the dry sweeping duct 115 to the dust collection chamber 113. The dust filter 180 filters out dust and waste from the airflow, leaving it in the dust collection chamber 113. In the lower garbage chamber 112, which is connected to the second outlet 1131 of the dust removal chamber 113, the airflow passes through the first outlet 1130 to the fan receiving chamber 114 to be discharged from the box 110, realizing the separate settling of garbage in the dry sweeping mode; in the washing and sweeping mode, the first dry sweeping air door 160 and the second dry sweeping air door 161 are closed and the washing and sweeping air door 163 is opened, so that the garbage and sewage entering the upper garbage chamber 111 settle in the upper garbage chamber 111 by gravity, and the airflow passes through the washing and sweeping air duct 116 to the fan receiving chamber 114 to be discharged from the box 110, realizing that the garbage in the washing and sweeping mode settles in the upper garbage chamber 111. In this way, the separate loading of large garbage, sewage and small garbage can be realized, which is convenient for subsequent garbage sorting and treatment.

[0101] In addition, separate dry sweeping air duct 115 and washing sweeping air duct 116 are set up to allow airflow in dry sweeping mode and washing sweeping mode respectively, which can avoid mutual interference between the two cleaning modes.

[0102] The second outlet 1131 is located at the lower part of the dust removal chamber 113, and the first outlet 1130 is located at the upper part of the dust removal chamber 113. The outlet of the dry cleaning duct 115 is connected to the middle of the dust removal chamber 113. In this way, the airflow carrying some garbage enters from the inlet of the dry cleaning duct 115 and flows downward. Then the airflow passes through the dust removal chamber 113 from bottom to top. Fine particles are blocked at the bottom of the dust removal filter element 180 and then fall and settle, so that fine particulate garbage settles in the dust removal chamber 113 and the lower garbage chamber 112.

[0103] The waste bin 100 also has a filter 190, which is located inside the upper waste chamber 111. The inlets of the dry sweeping air duct 115 and the washing air duct 116 are connected to the upper waste chamber 111 through the filter 190. In dry sweeping mode, the filter 190 can block large particles of waste in the airflow, allowing only fine waste to enter the dust collection chamber 113. This ensures that the waste settling in the dust collection chamber 113 and the lower waste chamber 112 consists of fine ash and other fine particles, facilitating subsequent unified processing of these fine particles. The clean airflow flows to the fan receiving chamber 114 and is finally discharged from the waste bin 100. In washing mode, the filter 190 filters out any remaining waste in the airflow, and the remaining clean airflow flows directly to the fan receiving chamber 114 and is finally discharged from the waste bin 100.

[0104] The filter screen 190 is located at the top of the upper garbage chamber 111. The height of the inlet of the dry sweeping air duct 115 and the height of the inlet of the washing air duct 116 are not lower than the filter screen 190. This can maximize the height of the airflow, so that more garbage will settle in the upper garbage chamber 111 under the action of gravity.

[0105] The working principle of the trash can 100 according to an embodiment of this application will be described by way of example below:

[0106] refer to Figure 6 During dry sweeping operations, the first dry sweeping damper 160 and the second dry sweeping damper 161 are open, while the sweeping damper 163 is closed. At this time, garbage enters the upper garbage chamber 111 through the suction cylinder 170. Some garbage settles into the upper garbage chamber 111 due to gravity, while some continues to pass through the filter screen 190 with the airflow. The filter screen 190 blocks some large particles of garbage, and the remaining fine garbage flows downwards into the dry sweeping duct 115 with the airflow. The airflow exiting the dry sweeping duct 115 then impacts the collision plate, causing some garbage to fall below the collision plate. The remaining garbage flows into the dust removal chamber 113 with the airflow. The airflow passes through the filter cylinder, filtering out dust and garbage, and then flows to the fan receiving chamber 114. At this time, large pieces of garbage remain in the upper garbage chamber 111, while fine dust remains in the dust removal chamber 113 and the lower garbage chamber 112. Clean air flows to the fan in the fan receiving chamber 114 and finally exits into the garbage bin 100.

[0107] refer to Figure 7When sweeping operations are performed, the first dry sweeping air door 160 is closed, while the sweeping air door 163 is open. At this time, the sweeper's spray bar uses high pressure to wash and reduce dust from the road surface garbage. The water-containing garbage enters the upper garbage chamber 111 through the suction pipe 170. Most of the garbage and sewage settle in the upper garbage chamber 111 by gravity. A small amount of garbage continues to pass through the filter screen 190 with the airflow. The filter screen 190 filters out the remaining garbage, and the clean airflow enters the sweeping air duct 116 and then flows to the fan receiving chamber 114. At this time, the garbage and sewage remain in the upper garbage chamber 111. The dust removal chamber 113 and the lower garbage chamber 112 are free of garbage and sewage. The clean air flows to the fan in the fan receiving chamber 114 and is finally discharged from the garbage bin 100.

[0108] This application also discloses a sweeper vehicle, which includes the garbage bin 100 described in the above embodiments.

[0109] In summary, this application discloses a garbage bin 100 and a sweeper truck. The upper and lower wet and dry zones of the garbage bin 100 each have independent rear doors that open and close, thus sealing the two cavities separately and preventing sewage from the upper zone from contaminating the lower dry zone. Furthermore, both rear doors can be automatically controlled, allowing the user to operate the opening and closing of the two rear doors from the driver's cab.

[0110] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
