Description

Technical Field

[0001] This invention relates to the technical field of box-type semi-trailers, and more particularly to an adjustable cargo box structure for box-type semi-trailers. Background Technology

[0002] During operation, freight vehicles require adequate ventilation and dust removal inside the cargo compartment to ensure the quality of transported goods. This is especially crucial when transporting agricultural products, food, precision equipment, and other goods with high air quality requirements. Currently, cargo compartment ventilation typically relies on fixed ventilation openings in the side walls for natural ventilation, while dust removal requires the installation of additional electric fans and spray systems.

[0003] Existing vehicle ventilation and dust removal devices have the following problems in practical applications: Reliance on external power sources results in high energy consumption: Existing ventilation and dust removal systems typically require independent electric fans and electric water pumps, consuming vehicle electricity and increasing operating costs. The energy consumption issue of continuously operating electric equipment is even more pronounced during long-distance transportation.

[0004] The filters are prone to clogging and difficult to clean: After long-term use, the filters in the ventilation vents are easily clogged by dust and debris, affecting ventilation efficiency. Existing systems usually require regular manual cleaning, but the timing and frequency of cleaning cannot be synchronized with actual usage. The problem is often only discovered when the filters are severely clogged, affecting the air quality inside the vehicle.

[0005] Spray dust suppression systems often use a one-way water supply, resulting in low utilization: Existing spray systems typically employ a one-way water pump, meaning the water used for spraying cannot be recycled. In bumpy vehicle environments, the one-way water supply may become unstable due to vibration, affecting the spraying effect.

[0006] Lack of linkage between ventilation and dust removal: In existing systems, ventilation and dust removal typically operate independently and require separate control, increasing operational complexity. Furthermore, they lack a purely mechanical linkage mechanism that automatically adjusts based on vehicle driving conditions.

[0007] Vehicle vibration energy is not utilized: During vehicle operation, vibrations are inevitable. This energy is usually absorbed or dissipated by the shock absorption system and is not effectively utilized for cabin environment control. Summary of the Invention

Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0009] In view of the problems existing in the adjustable cargo box structure of the existing box-type semi-trailer, the present invention is proposed.

[0010] Therefore, the purpose of this invention is to provide an adjustable cargo box structure for a box-type semi-trailer, which aims to improve dust removal and ventilation.

[0012] As a preferred embodiment of the adjustable cargo box structure of the box-type semi-trailer described in this invention, the ventilation component includes an air inlet, a filter plate is provided inside the air inlet, and a scraper is provided on one side of the air inlet.

[0013] As a preferred embodiment of the adjustable cargo box structure of the box-type semi-trailer described in this invention, wherein: an air inlet pipe is connected to one side of the air inlet, an exhaust pipe is connected to the bottom of the air inlet pipe, a one-way valve is provided inside the air inlet pipe, and an exhaust pipe is connected to one side of the air inlet pipe.

[0014] As a preferred embodiment of the adjustable cargo box structure of the box-type semi-trailer described in this invention, a movable piston is slidably arranged inside the exhaust pipe, and a compression ring is fixedly arranged on the outer surface of the bottom connecting rod of the movable piston.

[0015] As a preferred embodiment of the adjustable cargo box structure of the box-type semi-trailer described in this invention, a limit ring is slidably provided on the outer surface of the bottom connecting rod of the movable piston, a return spring is provided at the bottom of the limit ring, and a counterweight ball is fixedly provided at the bottom of the connecting rod.

[0016] As a preferred embodiment of the adjustable cargo box structure of the box-type semi-trailer described in this invention, the dust removal component includes a water squeezing box, the top of which is provided with a first water inlet hole, and the side of which is provided with a second water inlet hole.

[0017] As a preferred embodiment of the adjustable cargo box structure of the box-type semi-trailer described in this invention, the top of the squeezing box is provided with a first water outlet, and the bottom of the squeezing box is provided with a second water outlet.

[0018] As a preferred embodiment of the adjustable cargo box structure of the box-type semi-trailer described in this invention, a water-squeezing block is slidably arranged inside the water-squeezing box, a connecting rod is provided at the bottom of the water-squeezing block, and a first spring is sleeved on the outside of the connecting rod.

[0019] As a preferred embodiment of the adjustable cargo box structure of the box-type semi-trailer described in this invention, the first water outlet and the second water outlet are both connected to a first water outlet pipe, and the first water inlet and the second water inlet are both connected to a first water inlet pipe on one side.

[0020] As a preferred embodiment of the adjustable cargo box structure of the box-type semi-trailer described in this invention, the interior of the dewatering box is provided with a water-stopping component, the water-stopping component includes a fixed frame, the bottom of the fixed frame is slidably connected to a moving block, the top of the moving block is provided with a second spring, the top of the moving block is provided with a sealing rod, and the outer side of the sealing rod is sleeved and connected to the second spring.

[0021] The beneficial effects of this invention are: The ventilation and dust removal systems are driven entirely by the kinetic energy of vehicle movement, requiring zero external energy consumption. A moving piston, supported by a counterweight and a return spring, reciprocates with the vehicle's movement. When the piston moves downwards, it draws in air from the inlet and stores it; when it moves upwards, it discharges the stored air into the passenger compartment through the outlet pipe, thus refreshing and circulating the air inside the compartment. Simultaneously, a water-squeezing block reciprocates with the vehicle's movement, continuously squeezing water from the outlet pipe into the nozzles for spray dust removal. The entire ventilation and dust removal process is driven entirely by the kinetic energy generated by the vehicle's movement, requiring no external power source and achieving zero-energy operation.

[0022] The scraper and piston work in tandem to achieve self-cleaning of the air inlet: when the moving piston moves downward, it drives the compression ring and scraper to move downward synchronously, scraping away impurities blocking the air inlet; when the moving piston moves upward under the action of the return spring, the scraper moves upward again for a second scraping. The scraper continuously cleans the air inlet filter screen with the reciprocating motion of the piston, and the cleaning frequency is completely synchronized with the frequency of vehicle bumps. The stronger the bumps, the more frequent the cleaning, and the less likely the filter screen is to clog. No manual periodic cleaning is required.

[0023] The water-squeezing block features bidirectional water replenishment and dispensing, enabling continuous spraying: When the water-squeezing block moves downwards, the inlet pipe replenishes water to the top of the block through the first inlet hole, while water from the bottom of the block is squeezed into the outlet pipe through the second outlet hole for spraying; when the water-squeezing block moves upwards under the action of the spring, the inlet pipe replenishes water to the bottom of the block through the second inlet hole, while water from the top of the block is squeezed into the outlet pipe through the first outlet hole for spraying. Whether the water-squeezing block is moving upwards or downwards, water replenishment and dispensing can be achieved simultaneously, ensuring uninterrupted water supply and continuous spraying.

[0024] The system adaptively adjusts to withstand vehicle vibrations, increasing dust removal and ventilation as the ride becomes more bumpy: the more bumpy the vehicle travels, the higher the frequency and the greater the stroke of the moving piston and water-squeezing block, resulting in increased ventilation and spray volume. In conditions with significant bumps (such as construction zones or rural roads), dust levels inside the vehicle are typically higher, automatically enhancing ventilation and dust removal. Conversely, on smooth roads, ventilation and dust removal automatically decrease. This adaptive adjustment is entirely determined by the vehicle's vibration level and requires no electronic control.

[0025] Ventilation and dust removal are driven by the same source of vibration, working synergistically: both the moving piston and the water-squeezing block are driven by vehicle vibrations, naturally synchronizing the two functions. Ventilation introduces fresh outside air into the cabin, while the spray system settles airborne dust; both work together to improve the interior environment of the cabin.

Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.

[0039] Reference Figures 1-9 The present invention provides an embodiment, specifically an adjustable cargo box structure for a box-type semi-trailer.

[0040] Specifically: the carriage body 1, a ventilation component 2 is provided on one side of the carriage body 1, a dust removal component 3 is provided on one side of the ventilation component 2, at least one set of the ventilation component 2 and the dust removal component 3 is provided, a filter base plate 5 is provided at the bottom of the carriage body 1, and a shelf 4 is provided on top of the filter base plate 5, at least two sets of the shelf 4 are provided.

[0041] The ventilation component 2 includes an air inlet 21, inside which a filter plate is installed, and a scraper 22 is installed on one side of the air inlet 21. An air inlet pipe 23 is connected to one side of the air inlet 21, and an exhaust pipe 24 is connected to the bottom of the air inlet pipe 23. A one-way valve is installed inside the air inlet pipe 23, and an exhaust pipe 24 is connected to one side of the air inlet pipe 23. A movable piston 26 is slidably installed inside the exhaust pipe 24, and a compression ring 261 is fixedly installed on the outer surface of the bottom connecting rod of the movable piston 26. A limit ring 27 is slidably installed on the outer surface of the bottom connecting rod of the movable piston 26, and a return spring 28 is installed at the bottom of the limit ring 27. A counterweight ball 29 is fixedly installed at the bottom of the connecting rod. The dust removal component 3 includes a water squeezing box 31, with a first water inlet 311 at the top and a second water inlet 312 on one side of the water squeezing box 31. The squeezing box 31 has a first water outlet 313 at its top and a second water outlet 314 at its bottom. A squeezing block 32 is slidably disposed inside the squeezing box 31, with a connecting rod 321 at its bottom and a first spring 322 sleeved on the outside of the connecting rod 321. Both the first and second water outlets 313 and 314 are connected to a first water outlet pipe 33, and both the first and second water inlets 311 and 312 are connected to a first water inlet pipe 34 on one side. The squeezing box 31 also has a water-stopping component 35 inside, including a fixing frame 351. A moving block 352 is slidably connected to the bottom of the fixing frame 351, a second spring 353 is disposed on the top of the moving block 352, and a sealing rod 354 is disposed on the top of the moving block 352. The outer side of the sealing rod 354 is sleeved and connected to the second spring 353.

[0042] When goods need to be transported, different quantities and sizes of shelves 4 can be placed to meet different needs; When ventilation and dust removal are required during vehicle transportation, the moving piston 26 moves back and forth between the counterweight ball 29 and the return spring 28 due to vehicle bumps. When the moving piston 26 moves downward, air is drawn from the air inlet 21 into the air intake pipe 23 and the exhaust pipe 24 due to the change in internal pressure. At this time, a certain volume of air is stored inside. At the same time, the moving piston 26 and the compression ring 261 move downward synchronously, and the compression ring 261 is fixedly connected to the scraper 22, thereby driving the scraper 22 to scrape away the impurities blocked by the air inlet 21. When the moving piston 26 moves upward under the action of the return spring 28, the scraper 22 moves upward, thereby scraping away the impurities blocked by the air inlet 21 again. At the same time, the stored air is squeezed out by the moving piston 26 and discharged into the interior of the vehicle body 1 through the exhaust pipe 25, thereby discharging the original air through the bottom filter plate 5.

[0043] Similarly, when the squeezing block 32 moves downward, the water inlet pipe 34 replenishes water to the top of the squeezing block 32 through the first water inlet hole 311, while the water at the bottom is squeezed into the water outlet pipe 33 through the second water outlet hole 314, thereby spraying dust into the carriage body 1 through the nozzle. When the squeezing block 32 rises under the action of the first spring 322, the second water inlet hole 312 is no longer blocked by the squeezing block 32, so the water inlet pipe 34 replenishes water to the bottom of the squeezing block 32 through the second water inlet hole 312, and the squeezing block 32 squeezes the water above into the water outlet pipe 33 through the first water outlet hole 313 for spraying, thereby achieving the effect of continuous water replenishment and continuous water spraying. This invention fully utilizes the energy generated by vehicle operation, and the more bumpy the vehicle is, the more dust removal and ventilation are needed, and the stronger the dust removal and ventilation effect of this invention is.

[0044] Summary: During vehicle transportation, this device uses shelves 4 of varying quantities and sizes to meet different cargo requirements. When the vehicle travels on bumps, the moving piston 26 reciprocates under the action of the counterweight ball 29 and the return spring 28. When the moving piston 26 moves downward, it draws air from the air inlet 21 into the air intake pipe 23 and the exhaust pipe 24 for storage, while simultaneously driving the compression ring 261 and the scraper 22 downward to scrape away impurities blocked by the air inlet 21. When the moving piston 26 moves upward, the scraper 22 scrapes away impurities again, and the stored air is squeezed out and discharged into the carriage body 1 through the exhaust pipe 25, pushing the air out from the bottom filter plate 5. When the water-squeezing block 32 moves downward, the water inlet pipe 34 replenishes water above it through the first water inlet hole 311, and the water at the bottom is squeezed into the water outlet pipe 33 through the second water outlet hole 314 and sprayed through the nozzle to remove dust. When the water-squeezing block 32 moves upward under the action of the first spring 322, the water inlet pipe 34 replenishes water below it through the second water inlet hole 312, and the water above is squeezed into the water outlet pipe 33 through the first water outlet hole 313 to continue spraying, thus achieving continuous water replenishment and continuous water spraying. This invention fully utilizes the bump energy generated by vehicle operation; the stronger the bump, the stronger the dust removal and ventilation effect.
