Description

Technical Field

[0001] This utility model belongs to the technical field of vacuum cleaner truck body, specifically a vacuum cleaner truck body structure and a vacuum cleaner truck. Background Technology

[0002] With increasing environmental awareness and stricter requirements for the quality of living environments, the importance of the sanitation industry is becoming increasingly prominent. As the core support of the sanitation industry, the sanitation equipment industry is ushering in unprecedented development opportunities. Sanitation equipment covers a wide range of fields, including not only various sanitation vehicles such as garbage trucks, water trucks, sweepers, and vacuum trucks, but also numerous sanitation devices such as garbage bins and garbage compression equipment.

[0003] In the vast system of sanitation equipment, vacuum trucks play an irreplaceable role as key equipment for urban road cleaning. Traditional vacuum trucks mainly rely on the coordinated work of a fan and a suction nozzle to suck garbage into the garbage bin through pipes, and filter dust using a filter assembly arranged in the air duct. Traditional bin designs usually separate the garbage bin and the dust bin. In actual operation, during dust removal, the filter assembly is back-blown by the air path, causing the dust to settle to the bottom of the filter assembly; during operation, garbage enters the garbage bin through the suction nozzle pipe. After the operation is completed, the garbage and dust are dumped together in the landfill. However, this traditional design and operation method has revealed a series of problems that urgently need to be solved in the long-term use of the equipment: 1. The problem of dust caking: Due to long-term dust accumulation, the dust at the bottom of the dust bin is very prone to caking. Once the material hardens, cleaning becomes extremely difficult, requiring a large amount of manpower and involving a tedious and complex process. This undoubtedly severely impacts the progress of normal sanitation operations and significantly reduces work efficiency. Secondly, the layered design of the garbage bins and dust bins complicates the manufacturing process, greatly increasing production difficulty and cost. When equipment malfunctions and requires repair, this complex layered structure causes numerous inconveniences for maintenance personnel, significantly increasing the difficulty and time required for repairs, and severely affecting the normal use of the equipment.

[0004] Currently, most industry solutions to the dust caking problem involve increasing the slope of the dust bin, hoping to use inertia to prevent dust caking. However, the actual results are not ideal, and this method can also lead to excessive lifting angles of the waste bin, thus creating safety hazards. Utility Model Content

[0005] To address the problems of dust buildup, difficulty in cleaning, and overall manufacturing and maintenance difficulties in traditional vacuum cleaner truck bodies, this utility model provides a vacuum cleaner truck body structure and a vacuum cleaner truck.

[0006] This utility model is achieved through the following technical solution:

[0007] A vacuum cleaner truck body structure includes a tiltable body, comprising a rear garbage bin, a front dust bin, and a fan compartment located on one side of the dust bin; the garbage bin and the upper part of the dust bin are connected by a first channel, and the first channel is provided with a garbage filter screen for filtering garbage; an air damper is hinged between the bottom of the dust bin and the garbage bin; a garbage bin door is provided at the rear of the garbage bin; a filter cartridge assembly for filtering dust is installed inside the dust bin, and the outlet end of the filter cartridge assembly is connected to the fan compartment, which is provided with an exhaust fan; a flexible support layer is laid at the bottom of the dust bin, and the bottom of the dust bin is provided with several first back-blowing ports that can blow up the support layer; when the body is performing horizontal vacuuming operations, the air damper is closed, and when the body is tilted backward to discharge garbage, the air damper is opened.

[0008] A further improvement of this utility model is that the upper part of the damper is hinged to the partition plate by several hinges, and the damper is located on the side close to the garbage bin, and can overlap and seal with the partition plate.

[0009] A further improvement of this utility model is that a handle is provided on the side of the air damper near the trash can.

[0010] A further improvement of this utility model is that the lower front side of the dust box is provided with several second back-blowing ports that can blow the dust on the upper part of the support layer backward.

[0011] A further improvement of this utility model is that a number of suction pipes are provided through the bottom of the trash can, and a baffle is provided inside the trash can above the suction pipes.

[0012] A further improvement of this utility model is that the suction pipe is set vertically, and its upper end has an inclined notch that is higher in the front and lower in the back.

[0013] A further improvement of this utility model is that the baffle is inclined with the front lower and the rear higher.

[0014] A further improvement of this utility model is that a guide plate is connected to the upper part of the side of the dust box near the first channel.

[0015] A further improvement of this utility model is that a filter chamber is formed at the top of the filter cartridge assembly, and the front of the filter chamber is connected to the fan compartment through a second channel in the left and right directions.

[0016] This utility model is achieved through the following technical solution:

[0017] A vacuum cleaner truck includes a frame and a vacuum cleaner truck body structure. The bottom rear side of the body is rotatably connected to the frame, and a lifting cylinder capable of lifting the body is connected and installed between the frame and the body.

[0018] As can be seen from the above technical solutions, the beneficial effects of this utility model are:

[0019] When the hopper is operating horizontally for dust collection, the damper closes under its own weight, blocking the ash discharge channel. The exhaust fan inside the blower compartment creates negative pressure, drawing garbage and dust into the garbage bin. Garbage is filtered through the garbage filter and remains inside the bin, while dust enters the dust bin and is filtered from bottom to top through the filter cartridge assembly, where it accumulates on the support layer at the bottom. When the hopper tilts backward to discharge garbage, the damper automatically opens under its own weight. Compressed air blows through the first back-blowing port, causing the dust to float. The dust can then enter the garbage bin through the ash discharge channel and be discharged with the garbage through the rear garbage bin door. This effectively prevents dust caking, eliminates the need for manual cleaning, reduces maintenance time and labor costs, and improves the convenience and efficiency of ash discharge, thus enhancing the efficiency and quality of sanitation operations. Furthermore, the hopper has a simple structure, a reasonable distribution of compartments, and is easy to manufacture. The front-to-back arrangement of the garbage bin and dust bin facilitates maintenance of internal components. Attached Figure Description

[0028] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0029] like Figure 1-6 As shown, this utility model discloses a vacuum cleaner truck body structure, including a flip-up body 1. The body 1 includes a rear garbage bin 2, a front right dust bin 4, and a front left fan compartment 7 (located to the left of the dust bin 4). The upper parts of the garbage bin 2 and the dust bin 4 are connected by a first channel 3, and a garbage filter screen 10 for filtering garbage is provided at one end of the first channel 3 near the garbage bin 2 (rear end). A dust discharge channel is provided between the bottom of the dust bin 4 and the garbage bin 2, and the dust discharge channel is sealed by a hinged damper 12. A garbage bin door 13 is provided at the rear of the garbage bin 2. A filter cartridge assembly 11 for filtering dust is installed inside the dust bin 4. The upper outlet end of the filter cartridge assembly 11 is connected to the fan compartment 7, and an exhaust fan is provided inside the fan compartment 7. There is a gap between the bottom surface of the dust bin 4 and the bottom of the filter cartridge assembly 11. A flexible support layer 17 (such as flexible cloth) is laid at the bottom of the gap, and a number of first back-blowing ports 18 that can blow the support layer 17 upward are provided at the bottom of the dust bin 4.

[0030] When the housing 1 is in horizontal dust collection operation, the damper 12 closes under its own weight, blocking the ash discharge channel. The exhaust fan in the fan chamber 7 generates negative pressure, and garbage and dust are sucked into the garbage bin 2. The garbage is filtered through the garbage filter screen 10 and remains in the garbage bin 2. The dust enters the dust bin 4 and is filtered from bottom to top through the filter cartridge assembly 11. The dust is retained on the support layer 17 at the bottom of the filter cartridge assembly 11. When the housing 1 is tilted backward to discharge garbage, the damper 12 can automatically open under its own weight. Compressed air blows (fluctuates) the support layer 17 through the first back-blowing port 18, causing the dust to float (it can also blow the support layer 17 at intervals when the housing 1 is horizontal). The dust can enter the garbage bin 2 through the ash discharge channel (damper 12) and be discharged with the garbage through the rear garbage bin door 13. This effectively avoids dust caking, eliminates the need for manual cleaning, reduces maintenance time and labor costs, improves the convenience and efficiency of ash discharge, and improves the efficiency and quality of sanitation operations. Furthermore, the structure of the container 1 is simple, the distribution of each compartment is reasonable, and it is easy to manufacture. The garbage bin 2 and the dust bin 4 are arranged in front and behind, which facilitates the maintenance and operation of the internal components.

[0031] The support layer 17 can be fixed to the bottom of the dust box 4 by the binding rope along the edge to prevent the support layer 17 from folding or shifting.

[0032] The dust bin 4 has several second back-blowing ports 19 located on its lower front side, capable of blowing dust from the upper part of the support layer 17 backwards. These second back-blowing ports 19, working in conjunction with the first back-blowing port 18 at the bottom, allow the dust to be more thoroughly agitated and lifted, effectively preventing dust accumulation and caking on the support layer 17. This further improves the dust cleaning efficiency of the dust bin 4, ensuring timely and thorough cleaning (entering the waste bin 2 through the damper 12), maintaining the vacuum cleaner's good suction performance. Because the second back-blowing ports 19 promptly blow the dust towards the discharge direction, the possibility of dust adhering to and accumulating on other components within the dust bin 4 is reduced, decreasing the risk of clogging components such as the filter cartridge. This helps maintain the normal working condition of components like the filter cartridge, extending their service life and reducing equipment maintenance costs and frequency.

[0033] The damper 12 is hinged to the partition (the vertical partition between the garbage bin 2 and the dust bin 4) via several hinges 121 at its upper part. The damper 12 is located on the side closer to the garbage bin 2 and can overlap and seal with the partition. When the body 1 is in a horizontal state, the damper 12 blocks the ash discharge channel under its own weight, effectively preventing garbage in the garbage bin 2 and dust in the dust bin 4 from leaking from the connection between the damper 12 and the partition during the operation of the vacuum truck, ensuring the effectiveness of garbage collection and dust filtration. When the body 1 is tilted backward, the damper 12 automatically opens under its own weight via multiple hinges 121, facilitating ash discharge without manual operation, thus achieving convenience and efficiency in use.

[0034] like Figure 5 As shown, the damper 12 has a handle 122 on the side (rear side) near the garbage bin 2. The damper 12 can be manually opened by the handle 122, which makes operation convenient (such as discharging ash when the bin 1 is in a horizontal state or replacing the support layer 17).

[0035] The bottom of the trash can 2 is equipped with several suction pipes 8, and a baffle 9 is installed inside the trash can 2 above the suction pipes 8. The suction pipes 8 are used to collect trash and dust, and the baffle 9 is used to block the spread of trash, reduce the speed and range of trash dispersion, and restrict the direction of trash flow, making the trash more rationally distributed inside the trash can 2. In addition, the baffle 9 can prevent trash from falling back into the suction pipes 8, thus avoiding blockage of the suction pipes 8.

[0036] Furthermore, the suction pipe 8 is vertically positioned with an sloping opening at its upper end, higher at the front and lower at the back. This design fully considers the movement trajectory of the garbage under suction. When the vacuum truck is operating, garbage on the ground is more easily drawn into the garbage bin 2 along the angle of the sloping opening by the airflow; it also effectively increases the outlet area at the upper end of the suction pipe 8, preventing blockages and improving the smoothness of garbage entering the garbage bin 2 through the suction pipe 8.

[0037] Furthermore, the baffle 9 is inclined at the front and high at the back. This corresponds to the inclined notch structure of the suction pipe 8, which can more effectively guide the garbage flow into the garbage bin 2, making the garbage more reasonably distributed in the garbage bin 2, reducing the direct contact between the garbage and the front garbage filter screen 10, preventing the garbage from piling up and clogging the garbage filter screen 10, and improving the filtration effect.

[0038] The dust bin 4 is equipped with a guide plate 14 on the upper part of the side near the first channel 3. This guide plate directs the dust-laden airflow into the bottom of the dust bin 4, helping to prevent turbulence within the dust bin 4 and ensuring that the airflow passes smoothly through the filter cartridge assembly 11 for filtration. It also prevents direct impact on the filter cartridge assembly 11, thus extending its service life. During the cleaning process, the guide plate 14 helps the back-blowing airflow to better act on the dust on the filter cartridge assembly 11 and the support layer 17. The guide plate 14 can guide the back-blowing airflow to more accurately blow towards the areas that need cleaning, making it easier for dust to fall off the filter cartridge assembly 11 and the support layer 17, further improving the cleaning effect and ensuring that the vacuum cleaner maintains good performance during continuous operation.

[0039] The filter cartridge assembly 11 has a filter chamber 5 on its upper part, and the front of the filter chamber 5 is connected to the fan chamber 7 through a second channel 6 in the left and right directions. The arrangement of each chamber is reasonable and compact, easy to form, and convenient for maintenance.

[0040] like Figure 6As shown, this utility model also discloses a vacuum cleaner cart, including a frame 15 and the aforementioned vacuum cleaner cart body structure. The rear bottom of the body 1 is rotatably connected to the frame 15, and a lifting cylinder 16 capable of lifting the body 1 is connected and installed between the frame 15 and the body 1. By extending and retracting the lifting cylinder 16, the body 1 can be tilted backward to discharge garbage, greatly simplifying the garbage discharge process, saving a lot of manpower and time, and improving garbage disposal efficiency; it is convenient, efficient, and reliable to use.

[0041] When the vacuum truck body 1 is operating horizontally, the damper 12 closes under its own weight, blocking the ash discharge channel. The exhaust fan in the blower compartment 7 generates negative pressure, drawing garbage and dust into the garbage bin 2. The garbage is filtered through the garbage filter screen 10 and remains in the garbage bin 2, while the dust enters the dust bin 4 and is filtered from bottom to top through the filter cartridge assembly 11. The dust is retained on the support layer 17 at the bottom of the filter cartridge assembly 11. When the body 1 is tilted backward to discharge garbage, the damper 12 can automatically open under its own weight. Compressed air blows (fluctuates) onto the support layer 17 through the first back-blowing port 18, causing the dust to float (it can also blow onto the support layer 17 at intervals when the body 1 is horizontal). The dust can enter the garbage bin 2 through the ash discharge channel (damper 12) and be discharged with the garbage through the rear garbage bin door 13. This effectively prevents dust from caking, eliminates the need for manual cleaning, reduces maintenance time and labor costs, improves the convenience and efficiency of ash discharge, and enhances the efficiency and quality of sanitation operations. Furthermore, the structure of the container 1 is simple, the distribution of each compartment is reasonable, and it is easy to manufacture. The garbage bin 2 and the dust bin 4 are arranged in front and behind, which facilitates the maintenance and operation of the internal components.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
