Description

Technical Field

[0001] This utility model belongs to the field of mechanical technology and relates to a garbage can cleaning vehicle, and more particularly to a garbage can cleaning component of a garbage can cleaning vehicle. Background Technology

[0002] The current garbage can cleaning method involves sanitation workers collecting and transporting garbage cans from streets and residential areas to garbage transfer stations, dumping the garbage, and then manually cleaning the inner and outer walls of the garbage cans.

[0003] To reduce manpower, garbage can cleaning vehicles have been developed to achieve automatic garbage can cleaning. These vehicles typically include a cleaning chamber, a tilting mechanism for flipping the garbage can into the cleaning chamber, and cleaning components for cleaning the inner and outer walls of the garbage can. For example, a garbage can cleaning device (application number: 201620138759.0) disclosed in the Chinese Patent Database includes a closed housing, a tilting rear door assembly, a tilting structure, a hydraulic device, an electrical control device, at least one cleaning device, and related connecting components. The closed housing has a top cover door, where a top cover door opening / closing cylinder drives the top cover door via a top cover door opening / closing rotation shaft. One end of a single-sided cleaning moving cylinder is fixed to the top cover door. The tilting rear door assembly includes a clamping fixed seat assembly, a clamping movable seat assembly, and left and right clamping cylinders. The left and right clamping cylinders drive the clamping movable seat assembly. The clamping and fixing assembly moves up and down within the right and left guide rails. The flipping structure includes a rear door flipping cylinder, a power linkage, and an auxiliary linkage. The rear door flipping cylinder drives the power linkage and auxiliary linkage to rotate, while the power linkage drives the flipping rear door assembly to rotate around the rear door rotation axis, that is, rotating both the flipping rear door assembly and the trash can by 180° so that the trash can is inverted or in its initial state. The cleaning device includes an external cleaning device and an internal cleaning device, the number of which is adapted to the number of trash cans. The external cleaning device is used to clean the bottom and sides of the trash can, and the internal cleaning device is placed below the opening of the trash can. The external cleaning device includes a nozzle installed on the top, a single-sided cleaning pipeline and a nozzle connected thereto, and a double U-shaped three-sided rinsing pipeline and a nozzle connected thereto. The other end of the single-sided cleaning moving cylinder is connected to the single-sided cleaning pipeline and the nozzle connected thereto.

[0004] When the above-mentioned cleaning vehicle is in use, the double U-shaped three-sided flushing pipeline, the single-sided cleaning pipeline, and the external cleaning device are all driven up and down by hydraulic cylinders, and a specific telescopic sealing structure is required, which makes the overall structure more complex and affects the stability of operation. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a garbage bin cleaning component for a garbage bin cleaning vehicle that is simple in structure and stable in operation.

[0006] The objective of this utility model can be achieved through the following technical solution: a garbage bin cleaning component for a garbage bin cleaning vehicle. The cleaning vehicle includes a compartment with a cleaning chamber formed inside. A garbage bin inlet is located at the front of the cleaning chamber, and a drain outlet is located at the rear of the cleaning chamber. This cleaning component includes an outer cleaning component and an inner cleaning component, both disposed within the cleaning chamber. The inner and outer cleaning components are used to clean the inner and outer walls of the garbage bin, respectively. The outer cleaning component includes two outer cleaning pipes, each consisting of an inlet section and a drain section. One end of the inlet section extends out of the cleaning chamber. The features include: a fixed external cleaning pipeline with two pipelines arranged in a front-to-back configuration that do not obstruct the trash can inlet; an inverted U-shaped drainage section with one end connected to the other end of the inlet section and the other end of the drainage section closed; two drainage sections arranged side-by-side and located in front of and behind the internal cleaning assembly; an inverted U-shaped clearance cavity formed by the outer wall of the drainage section, the size of which is larger than the trash can inlet, with the trash can inlet facing the clearance cavity; and multiple external nozzles installed on each drainage section, with the spray coverage area formed by the multiple external nozzles covering the outer wall of the trash can.

[0007] Installing a sufficient number of external nozzles on the drainage section, with the spray coverage area formed by multiple external nozzles completely covering the outer wall of the trash can, means that in actual installation, only the external cleaning pipeline needs to be fixed in place. This has the advantages of simple structure and stable operation.

[0008] In the aforementioned trash can cleaning vehicle's trash can cleaning assembly, the aforementioned internal cleaning assembly includes brushes, an internal cleaning pipe and a frame, all of which are fixedly arranged. One end of the internal cleaning pipe extends out of the cleaning chamber, and the other end of the internal cleaning pipe is a straight drain section. The drain section is vertically arranged, and an internal nozzle is installed at the upper end of the drain section. The frame is equipped with a drive component and a hollow shaft. The hollow shaft is vertically rotatably mounted on the frame and is sleeved outside the drain section. The drive component is used to drive the hollow shaft to rotate. The brushes are strip-shaped and vertically arranged, and the length of the brushes matches the depth of the trash can. There are at least two brushes evenly distributed along the circumference of the hollow shaft. A connecting frame is fixed on the outer wall of the hollow shaft, and all brushes are mounted on the connecting frame.

[0009] When in use, the trash can is placed upside down on the internal cleaning assembly. Water entering the internal cleaning pipe is sprayed out from the internal nozzle to clean the bottom wall of the trash can and wet the brush bristles. The drive component drives the brush to rotate to clean the inner wall of the trash can.

[0010] The brush length is set to match the depth of the trash can, so that the inner wall of the trash can can be cleaned without moving the brush. In actual installation, only the internal cleaning pipeline needs to be fixed, which further simplifies the structure and improves the stability of operation.

[0011] In the aforementioned trash can cleaning vehicle's trash can cleaning assembly, the frame includes a horizontally positioned platform and multiple feet supporting the platform. A hollow shaft passes through the platform at its lower end, and the two are rotatably engaged. The drive component includes a motor positioned directly below the platform, connected to the lower end of the central shaft via a transmission structure. Positioning the motor directly below the platform effectively prevents water from splashing onto it, extending the motor's lifespan.

[0012] In the garbage bin cleaning component of the aforementioned garbage bin cleaning vehicle, the transmission structure includes a main gear fixed on the motor main shaft and a secondary gear fixed on the hollow shaft, and the main gear and the secondary gear mesh with each other, which has the advantages of simple structure and stable operation.

[0013] In the garbage can cleaning components of the aforementioned garbage can cleaning vehicle, an equipment cavity is also formed inside the vehicle compartment, and the equipment cavity and the cleaning cavity are not connected; a water pump is installed inside the equipment cavity, and a water distributor is installed at the outlet of the water pump. One end of the inner cleaning pipeline and the outer cleaning pipeline both extend into the equipment cavity and are connected to the outlet of the water distributor.

[0014] In the aforementioned garbage bin cleaning vehicle's garbage bin cleaning components, a closed water storage chamber is formed inside the vehicle compartment, and a water inlet is provided on the outer wall of the vehicle compartment to connect the water storage chamber to the outside. The water pump inlet is connected to the water storage chamber through a pipeline. The integrated water storage chamber inside the vehicle compartment provides the water required for cleaning, so that the cleaning vehicle does not need to rely on an external water source during use and can be adapted to more working conditions.

[0015] In the garbage can cleaning component of the garbage can cleaning vehicle mentioned above, multiple external nozzles are installed at both ends of each drainage section. The multiple external nozzles located at the same end of the drainage section are vertically and evenly distributed, and the spray nozzle of each external nozzle faces the inward cleaning component.

[0016] In the aforementioned trash can cleaning assembly of the trash can cleaning vehicle, the drainage section consists of a horizontal pipe and two vertical pipes for mounting external nozzles. Both ends of the horizontal pipe face downwards, while the other end of the water inlet section faces upwards. The upper ends of the two vertical pipes are rotatably inserted into both ends of the horizontal pipe, and both vertical pipes are sealed and fixedly connected to the horizontal pipe. The lower end of the vertical pipe corresponding to the water inlet section is rotatably inserted into the other end of the water inlet section, and the two are sealed and fixedly connected. The external nozzles are mounted on the vertical pipes. Both vertical pipes of the drainage section can rotate around a vertical axis to adjust the spray angle of the external nozzles, facilitating debugging.

[0017] Compared with existing technologies, the garbage bin cleaning components of this garbage bin cleaning vehicle have the following advantages: 1. Install a sufficient number of external nozzles on the drainage section, and ensure that the spray coverage area formed by multiple external nozzles completely covers the outer wall of the trash can. In this way, during actual installation, only the external cleaning pipeline needs to be fixed. This has the advantages of simple structure and stable operation.

[0018] 2. The brush length is set to match the depth of the trash can, so that the inner wall of the trash can can be cleaned without moving the brush. In actual installation, only the internal cleaning pipeline needs to be fixed, which further simplifies the structure and improves the stability of operation. Attached Figure Description

[0026] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0027] like Figure 1 As shown, in the garbage bin cleaning assembly of the garbage bin cleaning vehicle, the cleaning vehicle includes a compartment 1, within which a cleaning chamber 1a is formed. The compartment 1 has a garbage bin inlet 1b1 at the front of the cleaning chamber 1a, allowing garbage bins to extend into or out of the cleaning chamber 1a by tipping over. The compartment 1 also has a drain outlet 1c at the rear of the cleaning chamber 1a to discharge wastewater generated during cleaning. In the actual product, the bottom wall of the cleaning chamber 1a is inclined, and the drain outlet 1c is located at the lowest point of the bottom wall of the cleaning chamber 1a to quickly discharge wastewater.

[0028] The cleaning assembly includes an outer cleaning assembly and an inner cleaning assembly, both disposed within the cleaning chamber 1a, and the inner cleaning assembly and the outer cleaning assembly are used to clean the inner and outer walls of the trash can, respectively.

[0029] in, The external cleaning assembly includes two external cleaning pipes 2, which are fixedly installed. The two external cleaning pipes 2 are arranged one behind the other and neither obstructs the trash can inlet 1b1, ensuring that the trash can smoothly tip into or out of the cleaning chamber 1a. Figure 3 and Figure 4 As shown, the external cleaning pipeline 2 consists of an interconnected, tubular inlet section 2a and a drain section 2b. One end of the inlet section 2a extends out of the cleaning chamber 1a. The drain section 2b is U-shaped, with one end connected to the other end of the inlet section 2a, and the other end of the drain section 2b is closed. The two drain sections 2b are arranged side by side, located in front of and behind the internal cleaning assembly, respectively. The outer wall of the drain section 2b forms an U-shaped clearance cavity 2c. The horizontal axis of the clearance cavity 2c is parallel to the horizontal axis of the trash can inlet 1b1. The size of the clearance cavity 2c is larger than that of the trash can inlet 1b1, and the trash can inlet 1b1 is directly opposite the clearance cavity 2c. That is, at this time, the drain section 2b at the front does not block the trash can inlet 1b1. Each drain section 2b is equipped with multiple external nozzles 3, and the spray coverage area formed by the multiple external nozzles 3 covers the outer wall of the trash can. In the actual product, the side wall of the drainage section 2b is provided with the same number of threaded holes as the external nozzle 3, and the water inlet end of the external nozzle 3 is threaded into the threaded hole, so as to fix and connect the external nozzle 3 to the drainage section 2b.

[0030] Install a sufficient number of external nozzles 3 on the drainage section 2b, ensuring that the spray coverage area formed by the multiple external nozzles 3 completely covers the outer wall of the trash can. This simplifies installation by requiring only the external cleaning pipe 2 to be fixed in place, offering advantages such as simple structure and stable operation. Preferably, multiple external nozzles 3 are installed at both ends of each drainage section 2b, with the nozzles on the same end of the drainage section 2b arranged vertically and evenly, and each nozzle's spray nozzle facing the inner cleaning assembly.

[0031] Further explanation: The drainage section 2b consists of a horizontal pipe 2b1 and two vertical pipes 2b2 for installing the external nozzles 3. Both ends of the horizontal pipe 2b1 face downwards, while the other end of the inlet section 2a faces upwards. The upper ends of the two vertical pipes 2b2 are rotatably inserted into both ends of the horizontal pipe 2b1, and both vertical pipes 2b2 are sealed and fixedly connected to the horizontal pipe 2b1. Preferably, the vertical pipes 2b2 and the horizontal pipe 2b1 are welded together, and the outer wall of the vertical pipe 2b2 is sealed to the inner wall of the horizontal pipe 2b1 through a sealing ring. The lower end of the vertical pipe 2b2 corresponding to the inlet section 2a is rotatably inserted into the other end of the inlet section 2a, and the two are sealed and fixedly connected. Preferably, the vertical pipe 2b2 and the inlet section 2a are welded together, and the outer wall of the vertical pipe 2b2 is sealed to the inner wall of the inlet section 2a through a sealing ring. During actual installation, the spray angle of the outer nozzle 3 is adjusted by rotating the two vertical pipes 2b2. After the adjustment is completed, the two vertical pipes 2b2 are fixed, which has the advantage of convenient adjustment.

[0032] like Figure 1 , Figures 3 to 6 As shown, the internal cleaning assembly includes a brush 4, an internal cleaning pipe 5, and a frame 6, all fixedly arranged. One end of the internal cleaning pipe 5 extends out of the cleaning chamber 1a, and the other end is a straight drain section 5a, vertically arranged, with an internal nozzle 7 installed at its upper end. In the actual product, the internal nozzle 7 is vertically arranged, with its spray nozzle facing upwards, and its water inlet section 2a is threaded into the upper end of the drain section 5a. The frame 6 is equipped with a drive component and a hollow shaft 8. The hollow shaft 8 is vertically rotatably mounted on the frame 6, and is sleeved around the drain section 5a without contact between them. The drive component drives the hollow shaft 8 to rotate. The brush 4 is a pre-existing product; it is strip-shaped and vertically arranged, and its length matches the depth of the trash can. There are at least two brushes 4 and they are evenly distributed along the circumference of the hollow shaft 8. Each brush 4 includes a mounting plate and bristles disposed on one side of the mounting plate. A connecting frame 9 is fixed on the outer wall of the hollow shaft 8, and the brushes 4 are mounted on the connecting frame 9 through the mounting plate.

[0033] When in use, the trash can is placed upside down on the inner cleaning assembly. Water entering the inner cleaning pipe 5 is sprayed out from the inner nozzle 7 to clean the bottom wall of the trash can and wet the bristles of the brush 4. The driving component drives the brush 4 to rotate to clean the inner wall of the trash can.

[0034] The length of the brush 4 is set to match the depth of the trash can, so that the inner wall of the trash can can be cleaned without moving the brush 4. In actual installation, only the inner cleaning pipe 5 needs to be fixed, which further simplifies the structure and improves the stability of operation.

[0035] In this embodiment, It is preferred that both the external cleaning pipe 2 and the internal cleaning pipe 5 are made of stainless steel to ensure high hardness.

[0036] The frame 6 includes a horizontally arranged platform 6a and multiple feet supporting the platform 6a upwards. Preferably, there are four feet, which are respectively arranged around the platform 6a and fixed to the bottom wall of the cleaning chamber 1a. The platform 6a has a through hole for the lower end of the central shaft to pass through, and the hollow shaft 8 is rotatably engaged with the platform 6a. Specifically, a connecting cylinder 6b is vertically fixed on the platform 6a, and the connecting cylinder 6b is sleeved on the hollow shaft 8. A rolling bearing is provided between the hollow shaft 8 and the connecting cylinder 6b, and the inner and outer rings of the rolling bearing are respectively fixed to the hollow shaft 8 and the connecting cylinder 6b. Preferably, the hollow shaft 8 is sealed to the inner wall of the connecting cylinder 6b by an annular oil seal, and the rolling bearing is located below the annular oil seal.

[0037] The driving component includes a motor 10 positioned directly below the platform 6a, and the motor 10 is connected to the lower end of the central shaft via a transmission structure. Positioning the motor 10 directly below the platform 6a effectively prevents water from splashing onto it, extending its lifespan. Preferably, the motor 10 is fixed below the platform 6a by a base to further reduce the likelihood of water contact. The transmission structure includes a main gear 11 fixed to the motor 10's main shaft and a secondary gear fixed to the hollow shaft 8, with the main gear 11 and secondary gear meshing. This design offers advantages such as simple structure and stable operation. Of course, the transmission structure can also be a synchronous belt drive.

[0038] like Figure 1 , Figure 3 and Figure 4 As shown, the carriage 1 also contains an equipment cavity 1d, which is not connected to the cleaning cavity 1a. A water pump 12 is installed inside the equipment cavity 1d, and a water distributor 13 is installed at the outlet of the water pump 12. The water distributor 13 includes multiple outlets, with at least three outlets. One end of both the inner cleaning pipe 5 and the outer cleaning pipe 2 extends into the equipment cavity 1d and connects to the corresponding outlet of the water distributor 13. In the actual product, one end of both the inner cleaning pipe 5 and the outer cleaning pipe 2 is connected to the corresponding outlet of the water distributor 13 via a solenoid valve.

[0039] To further explain, the vehicle body 1 also has a closed water storage chamber 1e, and the outer wall of the vehicle body 1 is provided with a water inlet that connects the water storage chamber 1e to the outside. The inlet of the water pump 12 is connected to the water storage chamber 1e through a pipeline. The water storage chamber 1e is integrated into the vehicle body 1 to provide the water required for cleaning, so that the cleaning vehicle does not need to rely on an external water source when in use, and can be adapted to more working conditions.

[0040] In actual products, such as Figure 2As shown, a wastewater purification tank 14 is also installed outside the carriage 1, and the wastewater purification tank 14 is connected to the cleaning chamber 1a through the aforementioned drain outlet 1c. A three-way pipe 15 is installed at the inlet of the water storage chamber 1e. The three-way pipe 15 has three ends. The first end is connected to the water storage chamber 1e; the second end is equipped with a switch valve 16 for connecting to an external water supply source to supply water to the water storage chamber 1e; and a purification pipe 17 is provided on one side of the third end. One end of the purification pipe 17 is connected to the third end, and the other end of the purification pipe 17 is inserted into the wastewater purification tank. A filter 17a is installed in the middle of the purification pipe 17 to filter the sewage in the wastewater purification tank 14 and reintroduce it into the water storage chamber 1e to achieve water recycling.
